Counters can be dynamically defined, incremented, +** decremented, set, and deleted under application program +** control. +** +** The Counter Feature is intended to be used as instrumentation, +** not as operational data. If you need a counter for operational +** data, use native integral types. +** +** Counters are 32bit unsigned intergers. On overflow, a counter +** will wrap. No exception is recognized or reported. +** +** A counter can be dynamically created using a two level naming +** convention. A "handle" is returned when the counter is +** created. The counter can subsequently be addressed by its +** handle. An API is provided to get an existing counter's handle +** given the names with which it was originally created. +** Similarly, a counter's name can be retrieved given its handle. +** +** The counter naming convention is a two-level hierarchy. The +** QName is the higher level of the hierarchy; RName is the +** lower level. RNames can be thought of as existing within a +** QName. The same RName can exist within multiple QNames. QNames +** are unique. The NSPR Counter is not a near-zero overhead +** feature. Application designers should be aware of +** serialization issues when using the Counter API. Creating a +** counter locks a large asset, potentially causing a stall. This +** suggest that applications should create counters at component +** initialization, for example, and not create and destroy them +** willy-nilly. ... You have been warned. +** +** Incrementing and Adding to counters uses atomic operations. +** The performance of these operations will vary from platform +** to platform. On platforms where atomic operations are not +** supported the overhead may be substantial. +** +** When traversing the counter database with FindNext functions, +** the instantaneous values of any given counter is that at the +** moment of extraction. The state of the entire counter database +** may not be viewed as atomic. +** +** The counter interface may be disabled (No-Op'd) at compile +** time. When DEBUG is defined at compile time, the Counter +** Feature is compiled into NSPR and applications invoking it. +** When DEBUG is not defined, the counter macros compile to +** nothing. To force the Counter Feature to be compiled into an +** optimized build, define FORCE_NSPR_COUNTERS at compile time +** for both NSPR and the application intending to use it. +** +** Application designers should use the macro form of the Counter +** Feature methods to minimize performance impact in optimized +** builds. The macros normally compile to nothing on optimized +** builds. +** +** Application designers should be aware of the effects of +** debug and optimized build differences when using result of the +** Counter Feature macros in expressions. +** +** The Counter Feature is thread-safe and SMP safe. +** +** /lth. 09-Jun-1998. +*/ + +#include "prtypes.h" + +#ifdef VBOX_WITH_XPCOM_NAMESPACE_CLEANUP +#define PR_CreateCounter VBoxNsprPR_CreateCounter +#define PR_DestroyCounter VBoxNsprPR_DestroyCounter +#define PR_GetCounterHandleFromName VBoxNsprPR_GetCounterHandleFromName +#define PR_GetCounterNameFromHandle VBoxNsprPR_GetCounterNameFromHandle +#define PR_IncrementCounter VBoxNsprPR_IncrementCounter +#define PR_DecrementCounter VBoxNsprPR_DecrementCounter +#define PR_AddToCounter VBoxNsprPR_AddToCounter +#define PR_SubtractFromCounter VBoxNsprPR_SubtractFromCounter +#define PR_GetCounter VBoxNsprPR_GetCounter +#define PR_SetCounter VBoxNsprPR_SetCounter +#define PR_FindNextCounterQname VBoxNsprPR_FindNextCounterQname +#define PR_FindNextCounterRname VBoxNsprPR_FindNextCounterRname +#endif /* VBOX_WITH_XPCOM_NAMESPACE_CLEANUP */ + +PR_BEGIN_EXTERN_C + +/* +** Opaque counter handle type. +** ... don't even think of looking in here. +** +*/ +typedef void * PRCounterHandle; + +#define PRCOUNTER_NAME_MAX 31 +#define PRCOUNTER_DESC_MAX 255 + + + +/* ----------------------------------------------------------------------- +** FUNCTION: PR_DEFINE_COUNTER() -- Define a PRCounterHandle +** +** DESCRIPTION: PR_DEFINE_COUNTER() is used to define a counter +** handle. +** +*/ +#define PR_DEFINE_COUNTER(name) PRCounterHandle name + +/* ----------------------------------------------------------------------- +** FUNCTION: PR_INIT_COUNTER_HANDLE() -- Set the value of a PRCounterHandle +** +** DESCRIPTION: +** PR_INIT_COUNTER_HANDLE() sets the value of a PRCounterHandle +** to value. +** +*/ +#if defined(DEBUG) || defined(FORCE_NSPR_COUNTERS) +#define PR_INIT_COUNTER_HANDLE(handle,value)\ + (handle) = (PRCounterHandle)(value) +#else +#define PR_INIT_COUNTER_HANDLE(handle,value) +#endif + +/* ----------------------------------------------------------------------- +** FUNCTION: PR_CreateCounter() -- Create a counter +** +** DESCRIPTION: PR_CreateCounter() creates a counter object and +** initializes it to zero. +** +** The macro form takes as its first argument the name of the +** PRCounterHandle to receive the handle returned from +** PR_CreateCounter(). +** +** INPUTS: +** qName: The QName for the counter object.

Typically, +** the high order 24 bits are an identifier of which error table the +** error code is from, and the low order 8 bits are a sequential error +** number within the table. NSPR supports error tables whose first +** error code is not a multiple of 256, such error code assignments +** should be avoided when possible. +** +** Error table 0 is defined to match the UNIX system call error table +** (sys_errlist); this allows errno values to be used directly in the +** library. Other error table numbers are typically formed by +** compacting together the first four characters of the error table +** name. The mapping between characters in the name and numeric +** values in the error code are defined in a system-independent +** fashion, so that two systems that can pass integral values between +** them can reliably pass error codes without loss of meaning; this +** should work even if the character sets used are not the +** same. (However, if this is to be done, error table 0 should be +** avoided, since the local system call error tables may differ.) +** +** Libraries defining error codes need only provide a table mapping +** error code numbers to names and default English descriptions, +** calling a routine to install the table, making it ``known'' to NSPR +** library. Once installed, a table may not be removed. Any error +** code the library generates can be converted to the corresponding +** error message. There is also a default format for error codes +** accidentally returned before making the table known, which is of +** the form "unknown code foo 32", where "foo" would be the name of +** the table. +** +** Normally, the error code conversion routine only supports the +** languages "i-default" and "en", returning the error-table-provided +** English description for both languages. The application may +** provide a localization plugin, allowing support for additional +** languages. +** +**/ + +/**********************************************************************/ +/************************* TYPES AND CONSTANTS ************************/ +/**********************************************************************/ + +/* + * PRLanguageCode -- + * + * NSPR represents a language code as a non-negative integer. + * Languages 0 is always "i-default" the language you get without + * explicit negotiation.

After +** creating the LogModule, you can write to the log using the PR_LOG() +** macro. +** +** Initialization of the log service is handled by NSPR initialization. +** +** At execution time, you must enable the log service. To enable the +** log service, set the environment variable: NSPR_LOG_MODULES +** variable. +** +** NSPR_LOG_MODULES variable has the form: +** +** :[, :]* +** +** Where: +** is the name passed to PR_NewLogModule(). +** is a numeric constant, e.g. 5. This value is the maximum +** value of a log event, enumerated by PRLogModuleLevel, that you want +** written to the log. +** +** For example: to record all events of greater value than or equal to +** PR_LOG_ERROR for a LogModule names "gizmo", say: +** +** set NSPR_LOG_MODULES=gizmo:2 +** +** Note that you must specify the numeric value of PR_LOG_ERROR. +** +** Special LogModule names are provided for controlling NSPR's log +** service at execution time. These controls should be set in the +** NSPR_LOG_MODULES environment variable at execution time to affect +** NSPR's log service for your application. +** +** The special LogModule "all" enables all LogModules. To enable all +** LogModule calls to PR_LOG(), say: +** +** set NSPR_LOG_MODULES=all:5 +** +** The special LogModule name "sync" tells the NSPR log service to do +** unbuffered logging. +** +** The special LogModule name "bufsize:" tells NSPR to set the +** log buffer to . +** +** The environment variable NSPR_LOG_FILE specifies the log file to use +** unless the default of "stderr" is acceptable. For MS Windows +** systems, NSPR_LOG_FILE can be set to a special value: "WinDebug" +** (case sensitive). This value causes PR_LOG() output to be written +** using the Windows API OutputDebugString(). OutputDebugString() +** writes to the debugger window; some people find this helpful. +** +** +** To put log messages in your programs, use the PR_LOG macro: +** +** PR_LOG(, , (, *)); +** +** Where is the address of a PRLogModuleInfo structure, and +** is one of the levels defined by the enumeration: +** PRLogModuleLevel. is a printf() style of argument list.

NSPR Named Shared Memory is modeled on +** similar constructs in Unix and Windows operating systems. Shared +** memory allows multiple processes to access one or more common shared +** memory regions, using it as an inter-process communication channel. +** +** Notes on Platform Independence: +** NSPR Named Shared Memory is built on the native services offered +** by most platforms. The NSPR Named Shared Memory API tries to +** provide a least common denominator interface so that it works +** across all supported platforms. To ensure that it works everywhere, +** some platform considerations must be accomodated and the protocol +** for using NSPR Shared Memory API must be observed. +** +** Protocol: +** Multiple shared memories can be created using NSPR's Shared Memory +** feature. For each named shared memory, as defined by the name +** given in the PR_OpenSharedMemory() call, a protocol for using the +** shared memory API is required to ensure desired behavior. Failing +** to follow the protocol may yield unpredictable results. +** +** PR_OpenSharedMemory() will create the shared memory segment, if it +** does not already exist, or open a connection that the existing +** shared memory segment if it already exists. +** +** PR_AttachSharedMemory() should be called following +** PR_OpenSharedMemory() to map the memory segment to an address in +** the application's address space. +** +** PR_AttachSharedMemory() may be called to re-map a shared memory +** segment after detaching the same PRSharedMemory object. Be +** sure to detach it when done. +** +** PR_DetachSharedMemory() should be called to un-map the shared +** memory segment from the application's address space. +** +** PR_CloseSharedMemory() should be called when no further use of the +** PRSharedMemory object is required within a process. Following a +** call to PR_CloseSharedMemory() the PRSharedMemory object is +** invalid and cannot be reused. +** +** PR_DeleteSharedMemory() should be called before process +** termination. After calling PR_DeleteSharedMemory() any further use +** of the shared memory associated with the name may cause +** unpredictable results. +** +** Files: +** The name passed to PR_OpenSharedMemory() should be a valid filename +** for a unix platform. PR_OpenSharedMemory() creates file using the +** name passed in. Some platforms may mangle the name before creating +** the file and the shared memory. +** +** The unix implementation may use SysV IPC shared memory, Posix +** shared memory, or memory mapped files; the filename may used to +** define the namespace. On Windows, the name is significant, but +** there is no file associated with name. +** +** No assumptions about the persistence of data in the named file +** should be made. Depending on platform, the shared memory may be +** mapped onto system paging space and be discarded at process +** termination. +** +** All names provided to PR_OpenSharedMemory() should be valid +** filename syntax or name syntax for shared memory for the target +** platform. Referenced directories should have permissions +** appropriate for writing. +** +** Limits: +** Different platforms have limits on both the number and size of +** shared memory resources. The default system limits on some +** platforms may be smaller than your requirements. These limits may +** be adjusted on some platforms either via boot-time options or by +** setting the size of the system paging space to accomodate more +** and/or larger shared memory segment(s). +** +** Security: +** On unix platforms, depending on implementation, contents of the +** backing store for the shared memory can be exposed via the file +** system. Set permissions and or access controls at create and attach +** time to ensure you get the desired security. +** +** On windows platforms, no special security measures are provided. +** +** Example: +** The test case pr/tests/nameshm1.c provides an example of use as +** well as testing the operation of NSPR's Named Shared Memory. +** +** lth. 18-Aug-1999. +*/ + +#ifndef prshm_h___ +#define prshm_h___ + +#include "prtypes.h" +#include "prio.h" + +#ifdef VBOX_WITH_XPCOM_NAMESPACE_CLEANUP +#define PR_OpenSharedMemory VBoxNsprPR_OpenSharedMemory +#define PR_AttachSharedMemory VBoxNsprPR_AttachSharedMemory +#define PR_DetachSharedMemory VBoxNsprPR_DetachSharedMemory +#define PR_CloseSharedMemory VBoxNsprPR_CloseSharedMemory +#define PR_DeleteSharedMemory VBoxNsprPR_DeleteSharedMemory +#endif /* VBOX_WITH_XPCOM_NAMESPACE_CLEANUP */ + +PR_BEGIN_EXTERN_C + +/* +** Declare opaque type PRSharedMemory. +*/ +typedef struct PRSharedMemory PRSharedMemory; + +/* +** FUNCTION: PR_OpenSharedMemory() +** +** DESCRIPTION: +** PR_OpenSharedMemory() creates a new shared-memory segment or +** associates a previously created memory segment with name. +** +** When parameter create is (PR_SHM_EXCL | PR_SHM_CREATE) and the +** shared memory already exists, the function returns NULL with the +** error set to PR_FILE_EXISTS_ERROR. +** +** When parameter create is PR_SHM_CREATE and the shared memory +** already exists, a handle to that memory segment is returned.

The anonymous file-mapped shared memory provides an inheritable +** shared memory, as in: the child process inherits the shared memory. +** Compare the file-mapped anonymous shared memory to to a named shared +** memory described in prshm.h. The intent is to provide a shared +** memory that is accessable only by parent and child processes. ... +** It's a security thing. +** +** Depending on the underlying platform, the file-mapped shared memory +** may be backed by a file. ... surprise! ... On some platforms, no +** real file backs the shared memory. On platforms where the shared +** memory is backed by a file, the file's name in the filesystem is +** visible to other processes for only the duration of the creation of +** the file, hopefully a very short time. This restricts processess +** that do not inherit the shared memory from opening the file and +** reading or writing its contents. Further, when all processes +** using an anonymous shared memory terminate, the backing file is +** deleted. ... If you are not paranoid, you're not paying attention. +** +** The file-mapped shared memory requires a protocol for the parent +** process and child process to share the memory. NSPR provides two +** protocols. Use one or the other; don't mix and match. +** +** In the first protocol, the job of passing the inheritable shared +** memory is done via helper-functions with PR_CreateProcess(). In the +** second protocol, the parent process is responsible for creating the +** child process; the parent and child are mutually responsible for +** passing a FileMap string.

When implementing an +** application program an engineer may insert a "Trace" function +** call, passing arguments to be traced. The "Trace" function +** combines the user trace data with identifying data and +** writes this data in time ordered sequence into a circular +** in-memory buffer; when the buffer fills, it wraps. +** +** Functions are provided to set and/or re-configure the size of +** the trace buffer, control what events are recorded in the +** buffer, enable and disable tracing based on specific user +** supplied data and other control functions. Methods are provided +** to record the trace entries in the in-memory trace buffer to +** a file. +** +** Tracing may cause a performance degredation to the application +** depending on the number and placement of calls to the tracing +** facility. When tracing is compiled in and all tracing is +** disabled via the runtime controls, the overhead should be +** minimal. ... Famous last words, eh? +** +** When DEBUG is defined at compile time, the Trace Facility is +** compiled as part of NSPR and any application using NSPR's +** header files will have tracing compiled in. When DEBUG is not +** defined, the Trace Facility is not compiled into NSPR nor +** exported in its header files.

It differs from the general model in that a +** single "real" stack segment is used for execution of all +** threads. The context of the suspended threads is preserved +** in the md.context [and related members] of the PRThread +** structure. The stack context of the suspended thread is +** preserved in a "shadow stack" object. +** +** _MD_RESTORE_CONTEXT() implements most of the thread switching +** for NSPR's implementation of Win16 theads. +** +** Operations Notes: +** +** Function PR_NewStack() in prustack.c allocates a new +** PRThreadStack, PRStack, PRSegment, and a "shadow" stack +** for a thread. These structures are wired together to +** form the basis of Win16 threads. The thread and shadow +** stack structures are created as part of PR_CreateThread(). +** +** Note! Some special "magic" is applied to the "primordial" +** thread. The physical layout of the PRThread, PRThreadStack, +** shadow stack, ... is somewhat different. Watch yourself when +** mucking around with it. ... See _PR_MD_FINAL_INIT() for most +** of the special treatment of the primordial thread. +** +** Function _PR_MD_INIT_STACK() initializes the value of +** PRThreadStack member md.cxByteCount to zero; there +** is no context to be restored for a thread's initial +** dispatch. The value of member md.stackTop is set to +** point to the highest usable address on the shadow stack. +** This point corresponds to _pr_top_of_task_stack on the +** system's operating stack. +** +** _pr_top_of_task_stack points to a place on the system stack +** considered to be "close to the top". Stack context is preserved +** relative to this point. +** +** Reminder: In x86 architecture, the stack grows "down". +** That is: the stack pointer (SP register) is decremented +** to push objects onto the stack or when a call is made. +** +** Function _PR_MD_WAIT() invokes macro _MD_SWITCH_CONTEXT(); +** this causes the hardware registers to be preserved in a +** CATCHBUF structure using function Catch() [see _win16.h], +** then calls PR_Schedule() to select a new thread for dispatch. +** PR_Schedule() calls _MD_RESTORE_CONTEXT() to cause the thread +** being suspended's stack to be preserved, to restore the +** stack of the to-be-dispactched thread, and to restore the +** to-be-dispactched thread's hardware registers. +** +** At the moment _PR_MD_RESTORE_CONTEXT() is called, the stack +** pointer (SP) is less than the reference pointer +** _pr_top_of_task_stack. The distance difference between the SP and +** _pr_top_of_task_stack is the amount of stack that must be preserved. +** This value, cxByteCount, is calculated then preserved in the +** PRThreadStack.md.cxByteCount for later use (size of stack +** context to restore) when this thread is dispatched again. +** +** A C language for() loop is used to copy, byte-by-byte, the +** stack data being preserved starting at the "address of t" +** [Note: 't' is the argument passed to _PR_MD_RESTORE_CONTEXT()] +** for the length of cxByteCount. +** +** variables pSource and pTarget are the calculated source and +** destination pointers for the stack copy operation. These +** variables are static scope because they cannot be instantiated +** on the stack itself, since the stack is clobbered by restoring +** the to-be-dispatched thread's stack context. +** +** After preserving the suspended thread's stack and architectural +** context, the to-be-dispatched thread's stack context is copied +** from its shadow stack to the system operational stack. The copy +** is done in a small fragment of in-line assembly language. Note: +** In NSPR 1.0, a while() loop was used to do the copy; when compiled +** with the MS C 1.52c compiler, the short while loop used no +** stack variables. The Watcom compiler, specified for use on NSPR 2.0, +** uses stack variables to implement the same while loop. This is +** a no-no! The copy operation clobbers these variables making the +** results of the copy ... unpredictable ... So, a short piece of +** inline assembly language is used to effect the copy. +** +** Following the restoration of the to-be-dispatched thread's +** stack context, another short inline piece of assemble language +** is used to set the SP register to correspond to what it was +** when the to-be-dispatched thread was suspended. This value +** uses the thread's stack->md.cxByteCount as a negative offset +** from _pr_top_of_task_stack as the new value of SP. +** +** Finally, Function Throw() is called to restore the architectural +** context of the to-be-dispatched thread. +** +** At this point, the newly dispatched thread appears to resume +** execution following the _PR_MD_SWITCH_CONTEXT() macro. +** +** OK, this ain't rocket-science, but it can confuse you easily. +** If you have to work on this stuff, please take the time to +** draw, on paper, the structures (PRThread, PRThreadStack, +** PRSegment, the "shadow stack", the system stack and the related +** global variables).

Because of 3., we don't need a large table of powers of 10 + * for ten-to-e (just some small tables, e.g. of 10^k + * for 0 <= k <= 22). + */ + +/* + * #define IEEE_8087 for IEEE-arithmetic machines where the least + * significant byte has the lowest address. + * #define IEEE_MC68k for IEEE-arithmetic machines where the most + * significant byte has the lowest address. + * #define IEEE_ARM for IEEE-arithmetic machines where the two words + * in a double are stored in big endian order but the two shorts + * in a word are still stored in little endian order. + * #define Long int on machines with 32-bit ints and 64-bit longs. + * #define IBM for IBM mainframe-style floating-point arithmetic. + * #define VAX for VAX-style floating-point arithmetic (D_floating). + * #define No_leftright to omit left-right logic in fast floating-point + * computation of dtoa. + * #define Honor_FLT_ROUNDS if FLT_ROUNDS can assume the values 2 or 3 + * and strtod and dtoa should round accordingly. + * #define Check_FLT_ROUNDS if FLT_ROUNDS can assume the values 2 or 3 + * and Honor_FLT_ROUNDS is not #defined. + * #define RND_PRODQUOT to use rnd_prod and rnd_quot (assembly routines + * that use extended-precision instructions to compute rounded + * products and quotients) with IBM. + * #define ROUND_BIASED for IEEE-format with biased rounding. + * #define Inaccurate_Divide for IEEE-format with correctly rounded + * products but inaccurate quotients, e.g., for Intel i860. + * #define NO_LONG_LONG on machines that do not have a "long long" + * integer type (of >= 64 bits). On such machines, you can + * #define Just_16 to store 16 bits per 32-bit Long when doing + * high-precision integer arithmetic. Whether this speeds things + * up or slows things down depends on the machine and the number + * being converted. If long long is available and the name is + * something other than "long long", #define Llong to be the name, + * and if "unsigned Llong" does not work as an unsigned version of + * Llong, #define #ULLong to be the corresponding unsigned type. + * #define KR_headers for old-style C function headers. + * #define Bad_float_h if your system lacks a float.h or if it does not + * define some or all of DBL_DIG, DBL_MAX_10_EXP, DBL_MAX_EXP, + * FLT_RADIX, FLT_ROUNDS, and DBL_MAX. + * #define MALLOC your_malloc, where your_malloc(n) acts like malloc(n) + * if memory is available and otherwise does something you deem + * appropriate. If MALLOC is undefined, malloc will be invoked + * directly -- and assumed always to succeed. + * #define Omit_Private_Memory to omit logic (added Jan. 1998) for making + * memory allocations from a private pool of memory when possible. + * When used, the private pool is PRIVATE_MEM bytes long: 2304 bytes, + * unless #defined to be a different length. This default length + * suffices to get rid of MALLOC calls except for unusual cases, + * such as decimal-to-binary conversion of a very long string of + * digits. The longest string dtoa can return is about 751 bytes + * long. For conversions by strtod of strings of 800 digits and + * all dtoa conversions in single-threaded executions with 8-byte + * pointers, PRIVATE_MEM >= 7400 appears to suffice; with 4-byte + * pointers, PRIVATE_MEM >= 7112 appears adequate. + * #define INFNAN_CHECK on IEEE systems to cause strtod to check for + * Infinity and NaN (case insensitively). On some systems (e.g., + * some HP systems), it may be necessary to #define NAN_WORD0 + * appropriately -- to the most significant word of a quiet NaN. + * (On HP Series 700/800 machines, -DNAN_WORD0=0x7ff40000 works.) + * When INFNAN_CHECK is #defined and No_Hex_NaN is not #defined, + * strtod also accepts (case insensitively) strings of the form + * NaN(x), where x is a string of hexadecimal digits and spaces; + * if there is only one string of hexadecimal digits, it is taken + * for the 52 fraction bits of the resulting NaN; if there are two + * or more strings of hex digits, the first is for the high 20 bits, + * the second and subsequent for the low 32 bits, with intervening + * white space ignored; but if this results in none of the 52 + * fraction bits being on (an IEEE Infinity symbol), then NAN_WORD0 + * and NAN_WORD1 are used instead. + * #define MULTIPLE_THREADS if the system offers preemptively scheduled + * multiple threads. In this case, you must provide (or suitably + * #define) two locks, acquired by ACQUIRE_DTOA_LOCK(n) and freed + * by FREE_DTOA_LOCK(n) for n = 0 or 1. (The second lock, accessed + * in pow5mult, ensures lazy evaluation of only one copy of high + * powers of 5; omitting this lock would introduce a small + * probability of wasting memory, but would otherwise be harmless.) + * You must also invoke freedtoa(s) to free the value s returned by + * dtoa. You may do so whether or not MULTIPLE_THREADS is #defined. + * #define NO_IEEE_Scale to disable new (Feb. 1997) logic in strtod that + * avoids underflows on inputs whose result does not underflow. + * If you #define NO_IEEE_Scale on a machine that uses IEEE-format + * floating-point numbers and flushes underflows to zero rather + * than implementing gradual underflow, then you must also #define + * Sudden_Underflow. + * #define YES_ALIAS to permit aliasing certain double values with + * arrays of ULongs. This leads to slightly better code with + * some compilers and was always used prior to 19990916, but it + * is not strictly legal and can cause trouble with aggressively + * optimizing compilers (e.g., gcc 2.95.1 under -O2). + * #define USE_LOCALE to use the current locale's decimal_point value. + * #define SET_INEXACT if IEEE arithmetic is being used and extra + * computation should be done to set the inexact flag when the + * result is inexact and avoid setting inexact when the result + * is exact. In this case, dtoa.c must be compiled in + * an environment, perhaps provided by #include "dtoa.c" in a + * suitable wrapper, that defines two functions, + * int get_inexact(void); + * void clear_inexact(void); + * such that get_inexact() returns a nonzero value if the + * inexact bit is already set, and clear_inexact() sets the + * inexact bit to 0.

Either _PR_NTHREAD +is defined, in which case the PR_CreateThread() call always creates a +native kernel thread, or _PR_NTHREAD is not defined and PR_CreateThread() +always creates user level threads within the single, original process. This +source code is reflected in two directories, nspr20/pr/src/threads/native, and +nspr20/pr/src/threads/user. Although the PR_CreateThread() function has +a paramter to specify the "scope" of a thread, this parameter is not yet +used- except on solaris where it uses it to specify bound vs unbound threads. + +Phase 2 - next week + +The next step is to provide a combination of user and native threads. The +idea, of course, is to have some small number of native threads and each of +those threads be able to run user level threads. The number of native +threads created will most likely be proportional to the number of CPUs in +the system. For this reason, the specific set of native threads which are +used to run the user-level threads will be called "CPU" threads. + +The user level threads which will be run on the CPU threads are able to +run on any of the CPU threads available, and over the course of a user-level +thread's lifetime, it may drift from one CPU thread to another. All +user-level threads will compete for processing time via a single run queue. + +Creation of a CPU thread will be primarily controlled by NSPR itself or by +the user running a function PR_Concurrency(). The details of PR_Concurrency() +have not yet been worked out; but the idea is that the user can specify to +NSPR how many CPU threads are desired. + +In this system, user-level threads are created by using PR_CreateThread() and +specifying the PR_LOCAL_SCOPE option. LOCAL_SCOPE indicates that the thread +will be under the control of the "local" scheduler. Creating threads with +GLOBAL_SCOPE, on the other hand will create a thread which is under the +control of the system's scheduler. In otherwords, this creates a native thread +which is not a CPU thread; it runs a single thread task and never has more +than one task to run. LOCAL_SCOPE is much like creating a Solaris unbound +thread, while GLOBAL_SCOPE is similar to creating a Solaris bound thread. + +To implement this architecture, the source code will still maintain the "user" +and "native" directories which is has today. However a third directory +"combined" will also exist. To compile a version of NSPR which only creates +native threads, the user can define _PR_NTHREAD. For exclusive user-level +threads, do not define _PR_NTHREAD. To get the combined threads, define +_PR_NTHREAD and _PR_USE_CPUS. + + +Phase 3 - later than next week + +The goal is to eliminate the 3 directories. Once these three models are in +place, the remaining work will be to eliminate the native and user thread +directories for all platforms, so that the entire thread model is contained +within what is today called the "combined" model. This new and glorious +source code will attempt to make the "combined" model on any platforms which +provide the necessary underlying native threading, but will also be +capable of using exclusive user-level threads on systems which don't have +native threads. + diff --git a/src/libs/xpcom18a4/nsprpub/pr/src/threads/combined/prucpu.c b/src/libs/xpcom18a4/nsprpub/pr/src/threads/combined/prucpu.c new file mode 100644 index 00000000..a3938b1f --- /dev/null +++ b/src/libs/xpcom18a4/nsprpub/pr/src/threads/combined/prucpu.c @@ -0,0 +1,440 @@ +/* -*- Mode: C++; tab-width: 4; indent-tabs-mode: nil; c-basic-offset: 2 -*- */ +/* ***** BEGIN LICENSE BLOCK ***** + * Version: MPL 1.1/GPL 2.0/LGPL 2.1 + * + * The contents of this file are subject to the Mozilla Public License Version + * 1.1 (the "License"); you may not use this file except in compliance with + * the License.

The basic test operates as a single +** process. The process exercises all the API elements of the facility. +** This test also attempts to write to all locations in the shared +** memory. +** +** The second test is a client-server test. The client-server test +** creates a new instance of nameshm1, passing the -C argument to the +** new process; this creates the client-side process. The server-side +** (the instance of nameshm1 created from the command line) and the +** client-side interact via inter-process semaphores to verify that the +** shared memory segment can be read and written by both sides in a +** synchronized maner. +** +** Note: Because this test runs in two processes, the log files created +** by the test are not in chronological sequence; makes it hard to read. +** As a temporary circumvention, I changed the definition(s) of the +** _PUT_LOG() macro in prlog.c to force a flushall(), or equivalent. +** This causes the log entries to be emitted in true chronological +** order. +** +** Synopsis: nameshm1 [options] [name] +** +** Options: +** -d Enables debug trace via PR_LOG() +** -v Enables verbose mode debug trace via PR_LOG() +** -w Causes the basic test to attempt to write to the segment +** mapped as read-only. When this option is specified, the +** test should crash with a seg-fault; this is a destructive +** test and is considered successful when it seg-faults. +** +** -C Causes nameshm1 to start as the client-side of a +** client-server pair of processes. Only the instance +** of nameshm1 operating as the server-side process should +** specify the -C option when creating the client-side process; +** the -C option should not be specified at the command line. +** The client-side uses the shared memory segment created by +** the server-side to communicate with the server-side +** process. +** +** -p Specify the number of iterations the client-server tests +** should perform. Default: 1000. +** +** -s Size, in KBytes (1024), of the shared memory segment. +** Default: (10 * 1024) +** +** -i Number of client-side iterations. Default: 3 +** +** name specifies the name of the shared memory segment to be used. +** Default: /tmp/xxxNSPRshm +** +** +** See also: prshm.h +** +** /lth.

NSPR was asserting in ntio.c +** after PR_AcceptRead() had timed out. I/O performed subsequent to the +** call to PR_AcceptRead() could complete on a CPU other than the one +** on which it was started. The assert in ntio.c detected this, then +** asserted. +** +** Design: +** This test will fail with an assert in ntio.c if the problem it was +** designed to catch occurs. It returns 0 otherwise. +** +** The main() thread initializes and tears things down. A file is +** opened for writing; this file will be written to by AcceptThread() +** and JitterThread(). Main() creates a socket for reading, listens +** and binds the socket. +** +** ConnectThread() connects to the socket created by main, then polls +** the "state" variable. When state is AllDone, ConnectThread() exits. +** +** AcceptThread() calls PR_AcceptRead() on the socket. He fully expects +** it to time out. After the timeout, AccpetThread() interacts with +** JitterThread() via a common condition variable and the state +** variable. The two threads ping-pong back and forth, each thread +** writes the the file opened by main. This should provoke the +** condition reported by NES (if we didn't fix it). +** +** The failure is not solid. It may fail within a few ping-pongs between +** AcceptThread() and JitterThread() or may take a while. The default +** iteration count, jitter, is set by DEFAULT_JITTER.

The server initially creates +** a number of worker threads. Then, with the server running, a number of +** clients are created which start requesting service from the server. +** +** +** Modification History: +** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag. +** The debug mode will print all of the printfs associated with this test. +** The regress mode will be the default mode. Since the regress tool limits +** the output to a one line status:PASS or FAIL,all of the printf statements +** have been handled with an if (debug_mode) statement. +** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to +** recognize the return code from tha main program. +***********************************************************************/ + +/*********************************************************************** +** Includes +***********************************************************************/ +/* Used to get the command line option */ +#include "plgetopt.h" + +#include "nspr.h" +#include "pprthred.h" + +#include + +#define PORT 15004 +#define THREAD_STACKSIZE 0 + +static int _iterations = 1000;

All the functions that take a timeout argument + * are tested: PR_Sleep, socket I/O (PR_Accept is taken as a + * representative), PR_Poll, PR_WaitCondVar, PR_Wait, and + * PR_CWait. A thread of each thread scope (local, global, and + * global bound) is created to call each of these functions. + * The test should be started at the specified number of seconds + * (called the lead time) before a Y2K rollover test date. The + * timeout values for these threads will span over the rollover + * date by at least the specified number of seconds. For + * example, if the lead time is 5 seconds, the test should + * be started at time (D - 5), where D is a rollover date, and + * the threads will time out at or after time (D + 5). The + * timeout values for the threads are spaced one second apart. + * + * When a thread times out, it calls PR_IntervalNow() to verify + * that it did wait for the specified time. In addition, it + * calls a platform-native function to verify the actual elapsed + * time again, to rule out the possibility that PR_IntervalNow() + * is broken. We allow the actual elapsed time to deviate from + * the specified timeout by a certain tolerance (in milliseconds). + */ + +#include "nspr.h" +#include "plgetopt.h" + +#include +#include +#include +#if defined(XP_UNIX) +#include /* for gettimeofday */ +#endif +#if defined(WIN32) +#include +#include /* for _ftime */ +#endif + +#define DEFAULT_LEAD_TIME_SECS 5 +#define DEFAULT_TOLERANCE_MSECS 500 + +static PRBool debug_mode = PR_FALSE;

Python XPCOM Advanced Topics

+ +

This document contains a series of tidbits that don't fit +anywhere else. As the Python XPCOM Package documentation matures, most of +these topics will have another home.

+ +

XPCOM Services

+

An XPCOM service is simply a singleton registered by name.  Python has +full support for both using and implementing XPCOM services.  To use a +service, use xpcom.components.services just like the JavaScript +counterpart.  There is nothing special about implementing a service in +Python; see the standard XPCOM documentation on services for more information.

+ +

nsIVariant

+ +

There is (almost) full support for nsIVariant.  Any nsIVariant +parameters will automatically be translated to and from regular Python objects +giving, in effect, a multi-type parameter.  This should be automatic, so +there is not much else to say!  Note that if you really want, you can +create and pass your own nsIVariant object instead of a regular Python +object, thereby allowing explicit control over the type of variant created.

+ +

nsISupports Primitives.

+ +

There is a set of interfaces described in nsISupportsPrimitives.idl, which I +term collectively the nsISupports Primitives Interfaces.  These +are a set of interfaces a component can support to allow automatic conversion to +and from many basic types.  For example, an interface can define that it +supports the nsISupportsCString interface, and this could be used by any +program that wishes to get a string representation of the object.  If an +interface wishes to expose itself as a "boolean value", it may choose +to support the nsISupportsPRBool interface.

+

When you call an XPCOM object (i.e., you have an XPCOM interface you are +calling), you can use +the builtin functions str(), int(), long() etc., on the +object.  In the +case of str(), if the object does not support the nsISupportsCString +or nsISupportsString interfaces, the default string str() for the +object will be returned (i.e., what is normally returned for most XPCOM objects - +support for these interface is not very common!).  In the case of the numeric functions, a ValueError +exception will be raised if the objects do not support any interface that can be +used for the conversion. ValueError is used instead of TypeError, +as the type itself (i.e., an XPCOM object) can sometimes be used in this context - +hence it is the specific value of the object that is the problem.

+

The use of repr() on an XPCOM interface object prevents support +attempts for these interfaces, and allows you to see the +"real" object, rather than what the object wants you to see!

+

When you implement an XPCOM object, you have two choices for implementation +of these interfaces:

+
    +
  • You can explicitly handle these interfaces like any other interface.  + In this case, you have full control.  However, if you + implement only one of these standard interfaces, then you are only + overriding the default behavior for that specific interface - all other + interfaces not explicitly listed in your class will still get the behavior + described below.
    +
    • +
  • If your class does not define support for these interfaces, the framework + will use standard Python class semantics to implement them - i.e., if your + class provides a __str__ method, it will be used to implement nsISupportsCString + and nsISupportsString, if you provide __int__, __long__, + __float__ etc., methods, they will be used to implement the numeric + interfaces.  If your class defines no such special methods, then the + QueryInterface() for those interfaces fails (rather than the QI succeeding + and the operation to fetch the data failing).
    • +
+
+

This allows for an interesting feature that would not normally be +possible.  Consider Python code that does a str() on an  XPCOM +interface, and where the XPCOM interface itself is implemented in Python and +provides a __str__ method.  The str() on the original +interface queries for the nsISupportsCString interface.  The +Python implemented object responds to this interface and delegates to the __str__ +method. At the end of all this, str() returns the same result +as if the objects were native Python objects with no XPCOM layer in between.

+ +
+ +

Enumerators

+ +

The primary enumerator used by XPCOM is nsISimpleEnumerator. +Although the Python XPCOM package has full support for nsIEnumerator, +since this interface is not "scriptable", you should avoided using it in interfaces +you design.

+ +

When you use nsISimpleEnumerator from Python, the following enhancements +are available:

+
    +
  • The GetNext() method takes an optional IID as a parameter. If + this is specified, the returned object will be of this interface.  This + prevents the manual QueryInterface() generally required from other + languages.
    • +
  • There is a FetchBlock(num, [iid]) method, which fetches the + specified number of elements in one operation and returns a Python + list. This can be useful for large enumerator sets, so the loop + iterating the elements runs at full C++ speed.
    • +
+

nsIEnumerator has similar enhancements.

+

When implementing a Python XPCOM object, the Python class xpcom.server.enumerator.SimpleEnumerator() +can be used.  You can pass a standard Python sequence (list, etc), and it +will be correctly wrapped in an nsISimpleEnumerator interface.

+

Files

+

The Python XPCOM package provides an xpcom.file module.  This implements +a Python-like file object on top of the XPCOM/Mozilla stream interfaces.  +When run from within the Mozilla environment, this allows you to open almost any +URL supported by Mozilla (including "chrome://" etc.,).

+

See this module for more information, including test code.

+

XPCOM Object Identity

+

XPCOM has defined rules for object identity and for how objects must behave +in their QueryInterface() implementations.  The Python XPCOM framework +manages this for you; your code can return new Python instances etc., when +responding to new interfaces, and the framework itself will ensure the XPCOM +semantics are followed.  Critically, the framework provides no mechanism +for breaking these rules.

+

Policies

+

The Python XPCOM framework has the concept of "policies" that +define how XPCOM semantics are mapped to Python objects.  It is the policy +that implements delegation of QueryInterface(), translates property +references into direct property references, and failing that, "get_name" +and "set_name" calls, decides how to handle exceptions in the +component, and so on.

+

The default policy is very flexible and suitable for most purposes. +Indeed, the Komodo project has never had to implement a custom policy. +However, you should be aware the feature exists should you wish to do some +bizarre things, such as using Python as a bridge between XPCOM and some other +component technology.

Python XPCOM Package Architecture

+

Architecture

+

Much of the design for the Python XPCOM Package has been borrowed from the Python MS-COM +extensions in win32com. Most of the major limitations and drawbacks in the win32com +design have been addressed, mainly "auto-wrapping" of +interface objects, which is not supported by win32com.

+

Like win32com, this architecture includes the concept of client COM and server +COM.

+

Client COM:

+
    +
  • calls other interfaces
    • +
  • is supported by PyInterfaces implemented in C++, which assists +in making the COM calls
    • +
  • is supported by PyGateways, which assists in receiving +external COM calls and dispatching them to the correct Python object
    • +
  • is supported in the xpcom/client package
    • +
+

Server COM:

+
    +
  • implements interfaces for use by other XPCOM applications or components
    • +
  • is +supported in the xpcom/server package
    • +
+

The XPConnect framework is very powerful, and far exceeds what COM's +IDispatch can offer.  Thus, we are able to get by with far fewer interfaces +supported in the C++ level, and defer most things to the Python code that uses +XPConnect.  As a result, the requirement for a huge number of interfaces to +exist in the .pyd does not exist.  There are, however, a number of +interfaces that do require native C++ support: these are interfaces +required to "boot" the XPConnect support (i.e., the interfaces that are +used to get information about interfaces), and also two gateways that need to +work without interface information available. This last requirement is +due to the XPCOM shutdown-ordering - it may be a bug, but is not an unreasonable +amount of code anyway.

+

Auto-wrapping of COM objects is supported by both client COM and +server COM. For client COM, auto-wrapping means that the +Python programmer always sees Python "component" objects, rather than +raw C++ interface objects; to the user, it all appears to "just +work".  This is a major source of frustration in the win32com +framework.

+

For server COM, auto-wrapping means that you can +pass Python instances wherever a COM object is expected. If the Python +instance supports COM interfaces, by virtue of having a _com_interfaces_ +attribute that lists the interface requested, it will be automatically wrapped +in the correct COM object. 

+

Error Handling: The C++ framework has good error handling support, +and uses the XPCOM console service to log debug messages, Python exceptions and +tracebacks.  win32com does not have good exception/traceback support +at the C++ level, mainly because COM does not define a service like +the console where debug messages can go.  This does mean that in Mozilla +release builds, these debug messages are likely to be lost, but the --console +command line option to a release Mozilla will get them back.  Therefore, +the other error-support utilities, such as the error callbacks made on the +policy object, may be used.

+

Component Loader, Modules and Factories:  XPCOM has the concept +of a component loader - a module used to load all components of a +particular type.  For example, the moz.jsloader.1 component loads all +the JavaScript components. Similarly, the moz.pyloader.1 +component loads all Python components.  However, unlike +JavaScript, the Python component loader is actually implemented in Python +itself! Since the Python component loader can not be used to load +itself, this component has some special code, pyloader.dll, to boot-strap itself.

+

This means is that all XPCOM components, including the Python loader itself and all +XPCOM module and factory interfaces, are implemented in +Python. There are no components or interfaces implemented purely in C++ +in this entire package!

Building, Configuring and Testing Python XPCOM Package

+

This document attempts to explain how to build, configure and test the +Python XPCOM Package. This document assumes you have already successfully +built +Mozilla from source and your environment is currently set up for such a build - +see the Mozilla build documentation +for more information.

+

PyXPCOM can be built on Windows using either the nmake makefile.win +process, or the configure; gmake process used by Linux.

+

configure; gmake Instructions

+

Preparing for the build

+
    +
  • Apply the patch in bugzilla + bug 129216. (If this bug is marked as "FIXED", it probably + means there is no need to apply the patch and that these docs are out of + date)
    • +
  • On Linux, you must have Python built for dynamic linking.  ActivePython + 2.1 is one such build.
    • +
  • On Windows, you must have a Python source tree installed and built.  + Patches gratefully accepted that allow an installed Python to be used (it + should not be hard!)
    • +
  • Ensure the Python interpreter you wish to use is on your path, such that + "python" will execute it correctly.  The configure process + uses this to locate the Python support files.
    • +
+

Building

+
    +
  • From the top-level Mozilla directory, execute ./configure + --enable-extensions=python/xpcom. As per the Mozilla build + instructions, you may add this option to your .mozconfig file.  + If you wish to enable debugging, just enable it as you would normally for + Mozilla; PyXPCOM will pick up the same settings.
    + (On Windows you will need to execute sh ./configure ... if running + from a Command Prompt.  See the Mozilla + win32 specific gmake build instructions for more details.
    • +
  • Build the Mozilla tree as normal; PyXPCOM will automatically be + built.  Alternatively, change to the top-level PyXPCOM directory and + execute gmake in that directory.
    • +
+

PyXPCOM outside Mozilla

+

When you are using PyXPCOM from inside mozilla, no additional configuration +options should be necessary.  However, if you wish to use PyXPCOM from +stand-alone Python (ie, so you can write simple Python scripts that can be +executed normally and use XPCOM), then additional environment variables must be +setup.

+
    +
  • PYTHONPATH - PYTHONPATH needs to + be set appropriately. You must manually ensure that the mozilla/dist/bin/python + directory (which is where PyXPCOM was installed during the build process) is + listed.  Note that when PyXPCOM is used from within Mozilla (or any + other xpcom process), this path will automatically be added to sys.path.  + It is only when Python directly uses xpcom that this step is necessary.
    + If anything is wrong here you should get a normal ImportError.
    • +
+
+

Note that on Windows, the PYTHONPATH is generally maintained in the + Registry; however, you can set this variable at a DOS prompt, and it will still be +added to the core PYTHONPATH. +

+
    +
  • PATH, LD_LIBRARY_PATH, etc - On Windows, you + must ensure that the Mozilla bin directory is listed on your PATH, or that + you execute your scripts with the Mozilla bin directory as the current + directory.
    + On Linux, you must set your PATH and LD_LIBRARY_PATH variables + appropriately.  However, you may find it simpler and easier to use the run-mozilla.sh + script in the Mozilla bin directory.  For example, changing to the + Mozilla bin directory and executing:
    + ./run-mozilla.sh python ~/src/mozilla/extensions/python/xpcom/test/regrtest.py
    + should setup a correct environment and execute the PyXPCOM test suite.
    • +
+

Testing your Setup

+

The Python XPCOM Package has a complete test suite.

+

In the rest of this section, we walk through some simpler tests a step at a time, +to help diagnose any problems.

+

Note: We recommend you do all your testing outside of mozilla.exe; it is far simpler to test all of +this using the PyXPCOM package stand-alone.

+

Note: On Windows, if you use a debug build of Mozilla (i.e., in dist\WIN32_D.OBJ\bin), + you must use python_d.exe; if you use a release build (i.e., in + a dist\WIN32_O.OBJ\bin directory), you must use python.exe.  +makefile.stupid.win handles this automatically.

+

To test your setup:

+
    +
  1. Start Python, and check
    + >>> import xpcom
    + works. If not, check your PYTHONPATH - the + main PyXPCOM package can not be located.  Also check your PATH, + and if you are on Linux, remember that executing ./run-mozilla.sh python is + the easiest way.
    2. +
  2. Check
    + >>> import xpcom._xpcom
    + +works. If not, then most likely your Mozilla + directory is not on your path, or something is wrong with _xpcom(_d).pyd/_xpcommodule.so.
    3. + +
  3. Next run a simple test: test/test_misc.py. With a Windows debug build, the command may look like:
    + C:\Anywhere> python_d \src\python\xpcom\test\test_misc.py
    +     or on Linux
    + /home/user/src/mozilla/dist/bin$ python /home/user/src/python/xpcom/test/test_misc.py
    4. +
+

If you can't get this going, you won't get much further! (You may see a few +errors - that is OK, as long as it appears something worked!).  If +everything looks OK, the +next step is to register our test component and run our full test suite.

+

Registering the Loader and Test Component

+

First register the generic Python loader. For instructions, see the architecture +document. Do this only once, regardless of how many +Python components you have.  Then install the test component itself, and +finally you can test it!

+

Registering the Python Loader and Component

+

To register the Python Loader and Component:

+
    +
  1. Ensure the build process has put pyloader.dll (or modpyloader.so + for Unix), and the files py_test_component.py and py_test_component.idl into + the Mozilla bin/components directory.  If not, copy the files + there manually.
    2. +
  2. Run regxpcom (or ./run-mozilla.sh ./regxpcom if appropriate). regxpcom is a standard Mozilla + executable, found in the bin directory, that detects the new DLL and + .py + files and registers them accordingly.  You should + see a few messages that include the following:
    3. +
+
+ 
Registering: PythonComponentLoader
+Registered 1 Python components in pyloader.dll
+nsNativeComponentLoader: autoregistering succeeded
+Auto-registering all Python components in F:\src\mozilla\dist\WIN32_D.OBJ\bin\components
+Registering: PythonTestComponent
+Registered 1 Python components in py_test_component.py
+
+

If so (or you see no message at all), you are ready to run the test suite.

+

Note: If you execute this same step a second time, you will not +see any of the above mentioned messages. XPCOM knows that nothing has +changed since you last ran regxpcom, so nothing is registered.  If +you do not see these messages the first time you run it, there is the +possibility that some other process, possibly the build process, has already +executed this step.

+

Running the Test Suite

+

Before running the test suite, you should change to the mozilla/xpcom/sample +directory and build it.  This will build and install a sample component +which is used by the test suite.  If you do not have this component +available, some of the Python tests will fail.

+ +

To run the test suite, run xpcom/test/regrtest.py.  This runs the +tests and ensures that the test output is as expected.  If all tests +pass, you have a fully functioning Python XPCOM package.  Enjoy!

Python XPCOM Package Tutorial

+

This is a quick introduction to the Python XPCOM Package. We assume that you have a good understanding of Python and XPCOM, +and have experience both using and implementing XPCOM objects in some other +language (e.g., C++ or JavaScript). We do not attempt to +provide a tutorial to XPCOM or Python itself, only to using Python and + XPCOM.

+

This tutorial contains the following sections:

+ +

For anything not covered here, try the advanced +documentation, and if that fails, use the source, Luke!

+

Using XPCOM object and interfaces.

+

The techniques for using XPCOM in Python have been borrowed from JavaScript - +thus, the model described here should be quite familiar to existing JavaScript +XPCOM programmers.

+

xpcom.components module

+

When using an XPCOM object, the primary module used is the xpcom.components + module.  Using this module, you can get a Python object that supports any +scriptable XPCOM interface. Once you have this Python object, you can +simply call XPCOM methods on the object, as normal.

+

The xpcom.components module defines the following public +members:

+ + + + + + + + + + + + + +
NameDescription
classesA mapping (dictionary-like object) used to get XPCOM + "classes".  These are indexed by XPCOM contract ID, just + like the JavaScript object of the same name.   +

Example:

+ 
cls = components.classes["@mozilla.org/sample;1"]
+ob = cls.createInstance() # Now have an nsISupports
+
interfacesAn object that exposes all XPCOM interface IDs (IIDs).  + Like the JavaScript object of the same name, this object uses + "dot" notation, as demonstrated below. +

Example:

+ 
ob = cls.createInstance(components.interfaces.nsISample) 
+# Now have an nsISample
+
+

For many people, this is all you need to know. Consider the Mozilla Sample Component.  The Mozilla Sample +Component has a contract ID of @mozilla.org/sample;1, +and implements the nsISample interface.

+

Thus, a complete Python program that uses this component is shown below.

+
from xpcom import components
+cls = components.classes["@mozilla.org/sample;1"]
+ob = cls.createInstance() # no need to specify an IID for most components
+# nsISample defines a "value" property - let's use it!
+ob.value = "new value"
+if ob.value != "new value":
+    print "Eeek - what happened?"
+

And that is it - a complete Python program that uses XPCOM.

+

Implementing XPCOM Objects and Interfaces.

+

Implementing XPCOM objects is almost as simple as using them. The +basic strategy is this:

+
    +
  1. Create a standard Python source file, with a standard Python class.
    2. +
  2. Add some special attributes to your class for use by the Python XPCOM + framework. This controls the XPCOM behavior of your object.
    3. +
  3. Implement the XPCOM properties and methods of your classes as normal.
    4. +
  4. Put the Python source file in the Mozilla components directory.
    5. +
  5. Run regxpcom.
    6. +
+

Your component is now ready to be used.

+

Attributes

+

There are two classes of attributes: those used at runtime to define the object +behavior and those used at registration time to control object +registration.  Not all objects require registration, thus not all +Python XPCOM objects will have registration-related attributes.

+ + + + + + + + + + + + + + + + + + + + + + + + + +
AttributeDescription
_com_interfaces_The interface IDs (IIDs) supported by the component.  + For simplicity, this may be either a single IID, or a list of IIDs.  + There is no need to specify base interfaces, as all parent interfaces are + automatically supported. Thus, it is never necessary to nominate + nsISupports in the list of interfaces. +

This attribute is required. Objects without such an attribute are + deemed unsuitable for use as a XPCOM object.

_reg_contractid_The contract ID of the component.  Required if the + component requires registration (i.e., exists in the components directory).
_reg_clsid_The Class ID (CLSID) of the component, as a string in the + standard "{XXX-XXX-XXX-XXX}" format. Required if the + component requires registration (i.e., exists in the components directory).
_reg_registrar_Nominates a function that is called at registration + time. The default is for no extra function to be called. This can + be useful if a component has special registration requirements and needs + to hook into the registration process.
_reg_desc_The description of the XPCOM object. This may be used by + browsers or other such objects.  If not specified, the contract ID + is used.
+

Properties

+

A Python class can support XPCOM properties in one of two ways.  Either +a standard Python property of the same name can exist - our sample +component demonstrates this with the boolean_value property.  +Alternatively, the class can provide the get_propertyName(self) and set_propertyName(self, +value) functions (with propertyName changed to the appropriate value for the +property), and these functions will be called instead.

+

Example:  The Python XPCOM Test Component

+

As an example, examine the Python XPCOM Test Component.  This +code can be found in py_test_component.py.

+
from xpcom import components
+
+class PythonTestComponent:
+    _com_interfaces_ = components.interfaces.nsIPythonTestInterface
+    _reg_clsid_ = "{7EE4BDC6-CB53-42c1-A9E4-616B8E012ABA}"
+    _reg_contractid_ = "Python.TestComponent"
+    def __init__(self):
+        self.boolean_value = 1
+        ...
+    def do_boolean(self, p1, p2):
+        ret = p1 ^ p2
+        return ret, not ret, ret
+...
+

Note: This component only specifies the mandatory attributes - _com_interfaces, +_reg_clsid_ and _reg_contractid_.

+

This sample code demonstrates supporting the boolean_value attribute, +supported implicitly, as it is defined in the IDL and exists as a real Python +attribute of that name, and a method called do_boolean.

+

Tip: The xpcom/xpt.py Script

+

The xpcom/xpt.py script is a useful script that can generate the skeleton of a class for +any XPCOM interface.  Just specify the interface name on the command-line, +and paste the output into your source file.

+

This is the output of running this program over the nsISample +interface (i.e., assuming we wanted to implement a component that supported this +interface):

+
class nsISample:
+    _com_interfaces_ = xpcom.components.interfaces.nsISample
+    # If this object needs to be registered, the following 2 are also needed.
+    # _reg_clsid_ = {a new clsid generated for this object}
+    # _reg_contractid_ = "The.Object.Name"
+
+    def get_value( self ):
+        # Result: string
+        pass
+    def set_value( self, param0 ):
+        # Result: void - None
+        # In: param0: string
+        pass
+    def writeValue( self, param0 ):
+        # Result: void - None
+        # In: param0: string
+        pass
+    def poke( self, param0 ):
+        # Result: void - None
+        # In: param0: string
+        pass
+

Note: The types of the parameters and the function itself are included in +the comments. You need to implement the functions +themselves.  Another advantage of this script is that the hidden +parameters are handled for you; the comments indicate when parameters +have been hidden.

+

Parameters and Types

+

This section briefly describes the XPCOM type support in +Python.

+

All XPCOM interfaces define parameters of a specific type.  There is +currently no concept of a variant, or union of all types. Thus, the +conversion rules are very straightforward, and generally surprise free: for +any given XPCOM method, there is only one possible type for a given parameter.

+

Type Conversion Rules:

+ + +

Interface Flattening

+

Most people can ignore this information - Python XPCOM objects just +work.  However, if you are familiar with xpcom from C++ and the concept of QueryInterface, +you may like to read this.

+

Most components support the concept of "interface +flattening".  Such objects can report the interfaces they support, +allowing languages such as Python and Javascript avoid using QueryInterface.  +When you are using an XPCOM object from Python, you can just call methods and +reference properties without regard for the interface that implements it.

+

When multiple interfaces share the same method or property name, you can use +the name of the interface as a differentiator.  Thus, ob.nsIFoo.close() +will call close on ob's nsIFoo interface, while ob.nsIBar.close() +will use the nsIBar interface.  ob.close() is not defined.

Python XPCOM Package

+ +

Mozilla CVS Version - Last updated May 2002

+

This is the readme for the Python interface to XPCOM.

+

XPCOM is an acronym for "Cross Platform COM".  It has +come out of the Mozilla project, which +maintains the main XPCOM +project pages.  The Python XPCOM package is a set of Python bindings to +XPCOM, allowing a Python programmer to both use and implement XPCOM +interfaces.  If you don't know what Python +is, then none of this probably interests you at all!

+

This readme has links to the following information:

+ +

Note: This package requires Python 1.6 or later; we recommend using +the latest +official Python version.  This package works +very well with the latest ActivePython, +and does not require any external modules or packages beyond what is provided in +the core Python release for each platform.

+

About the Python XPCOM Package

+

The Python XPCOM Package was developed by ActiveState +Tool Corporation, and came out of their Komodo +project.  The Python XPCOM package is released under the Mozilla +Public License (MPL)

+

Please see the credits file for a list of +contributors.

+

Known Bugs/Issues

+
    +
  • No attempt is made to recurse sub-directories of the main +"components" directory.  This is because we may decide on some +smart scheme for recursion (similar to Python packages), and don't want people +to rely on simple recursive searches.
    • +
  • No unregistration support at all. The main Python Component Loader supports + unregistration, but the actual Python objects themselves do not support unregistration. It is unclear if the Component Loader + unregistration process needs to manually remove each component it is responsible +for.
    • +
  • All Python-implemented components unconditionally support +weak-references.  There is no way to disable this feature for any or all +components.  It is unclear if there is a need to prevent this, but it is +documented here just in case!

Release History

+

Version 0.90 - January 2001

+
    +
  • First public release.
    • +
+

Version 0.91 - January 2001

+
    +
  • Fix a seg fault on Linux when PYTHONPATH is not set.
    • +
  • Changes to allow building with stand-alone XPCOM.
    • +
+ +

Version 0.92 - May 2001

+

Implement interface flattening.  You should (almost) never need to use QueryInterface()!  +We are still 100% backwards compatible, so usage of QI still works - just is +generally not necessary.

+ +

Version 0.93 - May 2002

+ +

Implement nsIVariant and all new string types.  Complete move to +autoconf build system.

Building the Python XPCOM package.

+ +

This file describes how to build the Python XPCOM C++ sources.

+

There are the following steps

+ +

Testing etc is described in the main readme.

+

Configuring environment variables

+

MOZ_SRC 

+

Windows: Run the standard MOZENV.BAT used to build Mozilla.  This +sets MOZ_SRC

+

Unix: Set MOZ_SRC to point to the base source directory - assumes +"mozilla" sub-directory with mozilla directory tree under that. eg: assuming +/home/user/src/mozilla/dist/..."

+
export MOZ_SRC=/home/user/src
+

PYTHON_SRC

+

Windows: Set PYTHON_SRC to point to the base Python source directory.  +eg: assuming c:\src\python\PCBuild\...

set PYTHON_SRC=c:\src\python
+

Unix: Set PYTHON_SRC to point to the base of an "installed" Python +tree. eg:

export PYTHON_SRC=/usr/local/ActivePython-1.6
+

Building the sources

+

You must ensure some environment variables are setup.  The section on configuring +environment variables explains how.

+

There are 2 build processes to run All C++ sources are in the xpcom\src + directory.:

+

Windows

+
    +
  • Execute "compile.py" in this directory. This will take Setup.in, create an MSDev project, and build + ..\_xpcom.pyd and ..\_xpcom_d.pyd"
    • +
  • Change to the loader directory.
    • +
  • Run nmake -f makefile.win. This will create pyloader.dll, and + automatically copy it to the Mozilla build directory.
    • + +
+

Finally, run the tests, + where we also test everything imports correctly.

+

Linux

+

NOTE: Do not attempt to use "Setup.in" to create a Makefile 

+
    +
  • Run "make" in this directory.  This will create ../_xpcommodule.so
    • +
  • Run "make" in the loader directory. This will create libpyloader.so, + and copy it to the Mozilla directory.
    • + +
+

Finally, running the tests, + where we also test everything imports correctly.

Python Component Sample + +

+
+Last modified + +

+ +

XPConnect allows JavaScript +to transparantly access and manipulate XPCOM objects; + +

Big Deal, I hear you say! But it also works for Python!!! + +

+This sample demonstrates accessing a XPCOM object through XPConnect. +The JavaScript executed when this page loads creates an instance +of the Python object by +using the Components object, then accesses it through +the nsISample interface by calling QueryInterface: +
+

+netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
+var sample = Components.classes["component://mozilla/sample/sample-world"].createInstance();
+sample = sample.QueryInterface(Components.interfaces.nsISample);
+
+ +

+The buttons on the form are connected to JavaScript event handlers which +call the methods defined in Python + + +

Compiling the idl + +

The XPIDL compiler (xpidl on Unix, xpidl.exe on Windows, and a CodeWarrior plugin on Mac) +is compiled at build time (except on Mac) thus +you will have to build mozilla in order to test this out. If you +have already built mozilla then the compiler will be located at mozilla\dist\WIN32_D.OBJ\bin\xpidl.exe. + +

Once you have the XPIDL compiler enter the following command at your +prompt: +
D:\whereever\xpcom\test\test_component>d:\mozilla\dist\WIN32_D.OBJ\bin\xpidl -I +d:\mozilla\dist\idl -m typelib py_test_component.idl. You must then copy the generated .xpt file +to the mozilla component directory. + +

The -I d:\mozilla\dist\idl points the compiler to the folder +containing the other idl files, needed because nsISample.idl inherits from +nsISupports.idl. The -m typelib instruction tells the compiler +to build the .XPT typelib file.. + +

+For more information on compilation see the xpidl +compiler page. + +

All + of the compile-time options default to reasonable values for use on + most unix platforms. Compile -DWIN32 for reasonable defaults on windows. + You might later want to step through various compile options. + +* Why use this malloc? + + This is not the fastest, most space-conserving, most portable, or + most tunable malloc ever written. However it is among the fastest + while also being among the most space-conserving, portable and tunable. + Consistent balance across these factors results in a good general-purpose + allocator for malloc-intensive programs. + + The main properties of the algorithms are: + * For large (>= 512 bytes) requests, it is a pure best-fit allocator, + with ties normally decided via FIFO (i.e. least recently used). + * For small (<= 64 bytes by default) requests, it is a caching + allocator, that maintains pools of quickly recycled chunks. + * In between, and for combinations of large and small requests, it does + the best it can trying to meet both goals at once. + + Compared to 2.6.X versions, this version is generally faster, + especially for programs that allocate and free many small chunks. + + For a longer but slightly out of date high-level description, see + http://gee.cs.oswego.edu/dl/html/malloc.html + + You may already by default be using a c library containing a malloc + that is somehow based on some version of this malloc (for example in + linux). You might still want to use the one in this file in order to + customize settings or to avoid overheads associated with library + versions. + +* Synopsis of public routines + + (Much fuller descriptions are contained in the program documentation below.) + + malloc(size_t n); + Return a pointer to a newly allocated chunk of at least n bytes, or null + if no space is available. + free(Void_t* p); + Release the chunk of memory pointed to by p, or no effect if p is null. + realloc(Void_t* p, size_t n); + Return a pointer to a chunk of size n that contains the same data + as does chunk p up to the minimum of (n, p's size) bytes, or null + if no space is available. The returned pointer may or may not be + the same as p. If p is null, equivalent to malloc. Unless the + #define REALLOC_ZERO_BYTES_FREES below is set, realloc with a + size argument of zero (re)allocates a minimum-sized chunk. + memalign(size_t alignment, size_t n); + Return a pointer to a newly allocated chunk of n bytes, aligned + in accord with the alignment argument, which must be a power of + two. + valloc(size_t n); + Equivalent to memalign(pagesize, n), where pagesize is the page + size of the system (or as near to this as can be figured out from + all the includes/defines below.) + pvalloc(size_t n); + Equivalent to valloc(minimum-page-that-holds(n)), that is, + round up n to nearest pagesize. + calloc(size_t unit, size_t quantity); + Returns a pointer to quantity * unit bytes, with all locations + set to zero. + cfree(Void_t* p); + Equivalent to free(p). + malloc_trim(size_t pad); + Release all but pad bytes of freed top-most memory back + to the system. Return 1 if successful, else 0. + malloc_usable_size(Void_t* p); + Report the number usable allocated bytes associated with allocated + chunk p. This may or may not report more bytes than were requested, + due to alignment and minimum size constraints. + malloc_stats(); + Prints brief summary statistics on stderr. + mallinfo() + Returns (by copy) a struct containing various summary statistics. + mallopt(int parameter_number, int parameter_value) + Changes one of the tunable parameters described below. Returns + 1 if successful in changing the parameter, else 0. + +* Vital statistics: + + Assumed pointer representation: 4 or 8 bytes + (Thanks to Wolfram Gloger for contributing most of the + changes supporting dual 4/8.) + + Assumed size_t representation: 4 or 8 bytes + Note that size_t is allowed to be 4 bytes even if pointers are 8. + You can adjust this by defining INTERNAL_SIZE_T + + Alignment: 2 * sizeof(size_t) + (i.e., 8 byte alignment with 4byte size_t). This suffices for + nearly all current machines and C compilers. However, you can + define MALLOC_ALIGNMENT to be wider than this if necessary. + + Minimum overhead per allocated chunk: 4 or 8 bytes + Each malloced chunk has a hidden word of overhead holding size + and status information. + + Minimum allocated size: 4-byte ptrs: 16 bytes (including 4 overhead) + 8-byte ptrs: 24/32 bytes (including, 4/8 overhead) + + When a chunk is freed, 12 (for 4byte ptrs) or 20 (for 8 byte + ptrs but 4 byte size) or 24 (for 8/8) additional bytes are + needed; 4 (8) for a trailing size field and 8 (16) bytes for + free list pointers. Thus, the minimum allocatable size is + 16/24/32 bytes. + + Even a request for zero bytes (i.e., malloc(0)) returns a + pointer to something of the minimum allocatable size. + + The maximum overhead wastage (i.e., number of extra bytes + allocated than were requested in malloc) is less than or equal + to the minimum size, except for requests >= mmap_threshold that + are serviced via mmap(), where the worst case wastage is 2 * + sizeof(size_t) bytes plus the remainder from a system page (the + minimal mmap unit); typically 4096 bytes. + + Maximum allocated size: 4-byte size_t: 2^31 minus about two pages + 8-byte size_t: 2^63 minus about two pages + + It is assumed that (possibly signed) size_t values suffice + to represent chunk sizes. `Possibly signed' is due to the fact + that `size_t' may be defined on a system as either a signed or + an unsigned type. The ISO C standard says that it must be + unsigned, but a few systems are known not to adhere to this. + Additionally, even when size_t is unsigned, sbrk (which is by + default used to obtain memory from system) accepts signed + arguments, and may not be able to handle size_t-wide arguments + with negative sign bit. To be conservative, values that would + appear as negative after accounting for overhead and alignment + are rejected. + + Requests for sizes outside this range will perform an optional + failure action and then return null. (Requests may also + also fail because a system is out of memory.) + + Thread-safety: NOT thread-safe unless USE_MALLOC_LOCK defined + + When USE_MALLOC_LOCK is defined, wrappers are created to + surround every public call with either a pthread mutex or + a win32 critical section (depending on WIN32). This is not + especially fast, and can be a major bottleneck in programs with + many threads. It is designed only to provide minimal protection + in concurrent environments, and to provide a basis for + extensions. If you are using malloc in a concurrent program, + you would be far better off obtaining ptmalloc, which is + derived from a version of this malloc, and is well-tuned for + concurrent programs. (See http://www.malloc.de) + + Compliance: I believe it is compliant with the 1997 Single Unix Specification + + (See http://www.opennc.org). Probably other standards as well. + +* Limitations + + Here are some features that are NOT currently supported + + * No automated mechanism for fully checking that all accesses + to malloced memory stay within their bounds. However, there + are several add-ons and adaptations of this or other mallocs + available that do this. + * No support for compaction. + +* Synopsis of compile-time options: + + People have reported using previous versions of this malloc on all + versions of Unix, sometimes by tweaking some of the defines + below.

How should I represent files at run time? +// A. Use nsFileSpec. Using char* will lose information on some platforms. +// +// Q. Then what are nsFilePath and nsFileURL for? +// A. Only when you need a char* parameter for legacy code. +// +// Q. How should I represent files in a persistent way (eg, in a disk file)? +// A. Use nsPersistentFileDescriptor. Convert to and from nsFileSpec at run time. +// +// This suite provides the following services: +// +// 1. Encapsulates all platform-specific file details, so that files can be +// described correctly without any platform #ifdefs +// +// 2. Type safety. This will fix the problems that used to occur because people +// confused file paths. They used to use const char*, which could mean three +// or four different things. Bugs were introduced as people coded, right up +// to the moment Communicator 4.5 shipped. +// +// 3. Used in conjunction with nsFileStream.h (q.v.), this supports all the power +// and readability of the ansi stream syntax. +// +// Basic example: +// +// nsFilePath myPath("/Development/iotest.txt"); +// +// nsOutputFileStream testStream(nsFileSpec(myPath)); +// testStream << "Hello World" << nsEndl; +// +// 4. Handy methods for manipulating file specifiers safely, e.g. MakeUnique(), +// SetLeafName(), Exists(). +// +// 5.

xptcall Porting Guide

+ +

Overview

+ +
+ + xptcall is a +library that supports both invoking methods on arbitrary xpcom objects and +implementing classes whose objects can impersonate any xpcom interface. It does +this using platform specific assembly language code. This code needs to be +ported to all platforms that want to support xptcall (and thus mozilla). + +
+ +

+ +

Theory of operation

+ +
+ +There are really two pieces of functionality: invoke and stubs... + +

+ +The invoke functionality requires the implementation of the +following on each platform (from xptcall/public/xptcall.h): + +

+XPTC_PUBLIC_API(nsresult)
+XPTC_InvokeByIndex(nsISupports* that, PRUint32 methodIndex,
+                   PRUint32 paramCount, nsXPTCVariant* params);
+
+ +Calling code is expected to supply an array of nsXPTCVariant +structs. These are discriminated unions describing the type and value of each +parameter of the target function. The platform specific code then builds a call +frame and invokes the method indicated by the index methodIndex on +the xpcom interface that. + +

+ +Here are examples of this implementation for +Win32 +and +Linux x86, NetBSD x86, and FreeBSD. + +Both of these implementations use the basic strategy of: figure out how much +stack space is needed for the params, make the space in a new frame, copy the +params to that space, invoke the method, cleanup and return. C++ is used where +appropriate, Assembly language is used where necessary. Inline assembly language is used here, +but it is equally valid to use separate assembly language source files. Porters +can decide how best to do this for their platforms. + +

+ +The stubs functionality is more complex. The goal here is a class +whose vtbl can look like the vtbl of any arbitrary xpcom interface. Objects of +this class can then be built to impersonate any xpcom object. The base interface +for this is (from xptcall/public/xptcall.h): + +

+class nsXPTCStubBase : public nsISupports
+{
+public:
+    // Include generated vtbl stub declarations.
+    // These are virtual and *also* implemented by this class..
+#include "xptcstubsdecl.inc"
+
+    // The following methods must be provided by inheritor of this class.
+
+    // return a refcounted pointer to the InterfaceInfo for this object
+    // NOTE: on some platforms this MUST not fail or we crash!
+    NS_IMETHOD GetInterfaceInfo(nsIInterfaceInfo** info) = 0;
+
+    // call this method and return result
+    NS_IMETHOD CallMethod(PRUint16 methodIndex,
+                          const nsXPTMethodInfo* info,
+                          nsXPTCMiniVariant* params) = 0;
+};
+
+ +Code that wishes to make use of this stubs functionality (such as +XPConnect) implement a class +which inherits from nsXPTCStubBase and implements the +GetInterfaceInfo and CallMethod to let the +platform specific code know how to get interface information and how to dispatch methods +once their parameters have been pulled out of the platform specific calling +frame. + +

+ +Porters of this functionality implement the platform specific code for the +stub methods that fill the vtbl for this class. The idea here is that the +class has a vtbl full of a large number of generic stubs. All instances of this +class share that vtbl and the same stubs. The stubs forward calls to a platform +specific method that uses the interface information supplied by +the overridden GetInterfaceInfo to extract the parameters and build +an array of platform independent nsXPTCMiniVariant structs which +are in turn passed on to the overridden CallMethod. The +platform dependent code is responsible for doing any cleanup and returning. + +

+ +The stub methods are declared in xptcall/public/xptcstubsdecl.inc. +These are '#included' into the declaration of nsXPTCStubBase. A +similar include file (xptcall/public/xptcstubsdef.inc) +is expanded using platform specific macros to define the stub functions. These +'.inc' files are checked into cvs. However, they can be regenerated as necessary +(i.e. to change the number of stubs or to change their specific declaration) +using the Perl script xptcall/public/genstubs.pl. + +

+ +Here are examples of this implementation for Win32 +and Linux x86, NetBSD x86, and FreeBSD. +Both of these examples use inline assembly language. That is just how I +decided to do it. You can do it as you choose. + +

+ +The Win32 version is somewhat tighter because the __declspec(naked) feature +allows for very small stubs. However, the __stdcall requires the callee to clean +up the stack, so it is imperative that the interface information scheme allow +the code to determine the correct stack pointer fixup for return without fail, +else the process will crash. + +

+ +I opted to use inline assembler for the gcc Linux x86 port. I ended up with +larger stubs than I would have preferred rather than battle the compiler over +what would happen to the stack before my asm code began running. + +

+ +I believe that the non-assembly parts of these files can be copied and reused +with minimal (but not zero) platform specific tweaks. Feel free to copy and +paste as necessary. Please remember that safety and reliability are more +important than speed optimizations. This code is primarily used to connect XPCOM +components with JavaScript; function call overhead is a tiny part of the +time involved. + +

+ +I put together +xptcall/src/md/test + as a place to evolve the basic functionality as a port is coming together. +Not all of the functionality is exercised, but it is a place to get started. +xptcall/tests + has an api level test for XPTC_InvokeByIndex, but no tests for +the stubs functionality. Such a test ought to be written, but this has not +yet been done. + +

+ +A full 'test' at this point requires building the client and running the +XPConnect test called TestXPC in +mozilla/js/src/xpconnect/tests +. + +

+ +Getting these ports done is very important. Please let me know if you are interested in doing one. +I'll answer any questions as I get them. + +

+ + +Porting Status + + +

+Enclosed is xptcall for alpha/nt target.. +

+It is a variation of the IRIS port (only targeted for win32). +

+Notice the last 2 files (the change to mozilla\xpcom\build\makefile.win and +mozilla\xpcom\build) are needed because I was unable to figure how to do a +"declspecexport" from the assembler ASAXP ... if some knows how to do that then +those last 2 files won't be needed. +

+I have had someone look over this code at bridge.com (the entry point to +compaq/gem compiler team) and this code was given the OK. I consider it "done". +

+This code lives in the files where the name includes 'alpha' in the win32 directory.

+I am attaching a patch which contains my Linux Alpha xptcall code. +It passes TestXPTCInvoke and TestXPC on my machine which runs +kernel 2.2.7, glibc 2.1.1, and egcs 1.1.2. I have not tested it +with older GNU compilers such as gcc 2.8.x. From looking at the +Linux x86 code, I gather that the vtable layout is a little different +for those compilers and the code will need minor modifications +in order to work properly. +

+I am not sure how much of the code can be used for OpenVMS Alpha +and/or Digital UNIX. Currently the code is dependent on the g++ +name mangling convention and a few GNU extensions so I'm not sure +how useful it will be for the other systems. Hopefully the +comments in the code are detailed enough to help people attempting +a port. +

XPConnect Sample + +

+Ariel Blackenroth <arielb@rice.edu> +
+Michael Ang <mang@subcarrier.org> +
+Last modified + +

+ +

In the spirit of "worse is better" this somewhat rough guide is being +released to the world. It will be expanded upon and improved. + +

XPConnect allows JavaScript +to transparantly access and manipulate XPCOM objects; this communication +between JavaScript and +native code is done by having their interfaces defined in the XPIDL interface +definition language. See the Roadmap +for documentation on XPCOM, XPConnect, XPTCall and XPIDL for more information. + +

Overview + +

+This sample demonstrates accessing a XPCOM object through XPConnect. +The JavaScript executed when this page loads creates an instance +of the object by +using the Components object, then accesses it through +the nsISample interface by calling QueryInterface: +
+

+netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
+var sample = Components.classes["@mozilla.org/sample;1"].createInstance();
+sample = sample.QueryInterface(Components.interfaces.nsISample);
+
+ +

+The buttons on the form are connected to JavaScript event handlers which +call the methods defined in C++. + + +

nsISample.idl +

This is the interface declaration for the XPCOM object. It defines +two functions, their parameters, and one attribute. It also defines +the interface's id. The idl file is compiled by the xpidl compiler +into a C++ header, nsISample.h and a .xpt file which is a binary representation +of the interface used at runtime. +
attribute string value; +
void writeValue(in string aPrefix); +
void poke(in string aValue); +

nsSample.cpp +

This contains the implementation of nsISample.idl. SampleImpl +inherits from nsISample.h, the header dynamically created by the xpidl +compiler. The attribute Value has been expanded into a get and set +and the return values have been modified to NS_IMETHOD, a success status +for the method. The macro NS_DECL_ISUPPORTS, defined in mozilla/xpcom/public/nsISupportsUtils.h +defines the inherited methods from nsISupports.h. +
NS_IMPL_ISUPPORTS1(SampleImpl, nsISample) +
In the constructor, the macro NS_INIT_REFCNT is called which sets the +reference count to 0.

+Note that the methods in the C++ bindings use InterCaps style, while the IDL +and JavaScript versions should use interCaps naming. The JavaScript binding +matches the case of the IDL, except QueryInterface. +

nsSampleFactory.cpp +

This is the class which builds the instance of the nsSample class. +The COM framework uses factories to create instance of implementations +rather than having the implementations instatiate themselves in order to +increase portability of code. This factory inherits from nsFactory, +which is also an XPCOM object. To gain more knowledge of factories +see the generic +factory document or the Modularization techniques document. +

nsSample.js +

This file implements the nsISample interface, and associated factory glue, +in JavaScript. + +

Compiling the idl + +

The XPIDL compiler (xpidl on Unix, xpidl.exe on Windows, and a CodeWarrior plugin on Mac) +is compiled at build time (except on Mac) thus +you will have to build mozilla in order to test this out. If you +have already built mozilla then the compiler will be located at mozilla\dist\WIN32_D.OBJ\bin\xpidl.exe. + +

Once you have the XPIDL compiler enter the following command at your +prompt: +
D:\mozilla\xpcom\sample>d:\mozilla\dist\WIN32_D.OBJ\bin\xpidl -I +d:\mozilla\dist\idl -m header nsISample.idl + +

The -I d:\mozilla\dist\idl points the compiler to the folder +containing the other idl files, needed because nsISample.idl inherits from +nsISupports.idl. The -m header instruction tells the compiler +to build the C++ header. To build the .xpt file substitute -m +typelib. + +

+For more information on compilation see the xpidl +compiler page. + +

Building the Sample + +

To build the Sample just enter +
d:\mozilla\xpcom\sample>nmake /f makefile.win + +

In order to do this you need to have your environment variables set +correctly. See the Build +page for more information. + +

Running the sample +

Using Mozilla, load +resource://res/samples/xpconnect-sample.html (i.e. what +you're reading now). Pay attention +to the console when clicking "write". Notice that the value +printed is calculated in C++ code defined in nsSample.cpp. + + + + +

+ + + + + + + + +

+ +

+JavaScript and form source: + + +

+<script>
+/* to use nsSample.js version, use "@mozilla.org/jssample;1" */
+netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
+var sample = Components.classes["@mozilla.org/sample;1"].createInstance();
+sample = sample.QueryInterface(Components.interfaces.nsISample);
+dump("sample = " + sample + "\n");
+
+function get()
+{
+  netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");  var field = document.getElementById('Value');
+  field.value = sample.value;
+}
+
+function set()
+{
+  netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");  var field = document.getElementById('Value');
+  sample.value = field.value;
+}
+
+function poke()
+{
+  netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");  var field = document.getElementById('Value');
+  sample.poke(field.value);
+}
+
+function sampleWrite()
+{
+  netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
+  sample.writeValue("here is what I'm writing: ");
+}
+</script>

+
+ is there any string doc? +
+
+ Yes, you're soaking in it! +
+ + + + +
+ I have a string, how do I get a pointer to the characters? +
+
+ You want to avoid this situation. + In your own interfaces, prefer string types over raw pointers. + Any interface that wants to process a string using a single pointer is making two expensive assumptions. + First, that the string is stored in one contiguous hunk; and + second, that the string is zero-terminated. + If this isn't the case, + then to get a pointer, storage must be allocated and the entire string must be copied to it and zero-terminated. + You may not be able to avoid needing a pointer when interacting with system calls. +
+
+ Some string classes guarantee that they are `flat'. + That is, that their data is stored in one contiguous zero-terminated hunk. + This does not imply that there are no embedded nulls. Caveat emptor. + All strings that explicitly promise flatness + inherit from the class nsAFlatString + or nsAFlatCString + and can produce a constant pointer to their data with the get() member function. + Even strings that don't explicitly promise to be flat + may happen to be flat. + The helper function PromiseFlatString will produce + a const dependent string that is guaranteed to be flat. + If you use this on a string that already happens to be flat, + the result is simply a reference through to that string. + Otherwise, + PromiseFlatString does the work to allocate, copy, terminate, and manage + a temporary flat string. + Since the result of PromiseFlatString is a temporary, + you must be careful not to get and hold a pointer to its data for longer than the temporary itself lives. +
+
+
+
+  /* I have a string, how do I get a pointer to the characters? */
+
+extern void EvilNarrowOSFunction( const char* );    // evil OS routines that want a pointers
+extern void EvilWideOSFunction( const PRUnichar* );
+
+void func( const nsAString& aString, const nsACString& aCString )
+  {
+    EvilWideOSFunction( NS_LITERAL_STRING("Hello, World!").get() );
+      // literal strings are flat already (as are |nsString|s, et al), just use |.get()|
+
+    EvilWideOSFunction( PromiseFlatString(aString).get() );
+      // for strings that don't explicitly guarantee flatness, use |PromiseFlatString|
+
+
+      // beware holding the pointer for longer than the life of the promise
+    const PRUnichar* wp = PromiseFlatString(aString).get(); // BAD! |wp| dangles
+    EvilWideOSFunction(wp);
+
+      // if you really need to use the pointer from |PromiseFlatString| in more than one expression...
+    const nsAFlatString& flat = PromiseFlatString(aString);
+    EvilWideOSFunction(flat.get());
+    SomeOtherFunction(flat.get());
+
+      // similarly for |char| strings
+    EvilNarrowOSFunction( PromiseFlatCString(aCString).get() );
+  }
+
+
+
+ + + + +
+ How do I get a particular character out of a string? +
+
+ Flat strings provide operator[] and CharAt(). + All strings provide First(), Last(), and access with iterators. + Don't promise a string flat just to do character indexing. + Prefer, instead, to get an iterator and advance it to the position you care about. +
+
+
+
+  /* How do I get a particular character out of a string? */
+
+PRUnichar Get5thCharacterOf( const nsAString& aString )
+  {
+    if ( aString.Length() >= 5 )
+      {
+        nsAString::const_iterator iter;
+        aString.BeginReading(iter); // make |iter| point to the beginning of |aString|
+        iter.advance(5);
+        return *iter;
+      }
+
+    return PRUnichar(0);
+  }
+
+
+
+
+ Using iterators isn't as bad as the example above makes it feel. + The typical use is for advancing through a string, examining many characters. +

+ How do I convert from one encoding to another? +
+
+
+ + + + +
+ How do I create a string? +
+
+
+ + + +
+ What is the best way to return a string? +
+
+

+ There are several reasonable ways to produce a string result from a function. + If you are already holding the answer as a sharable string, + you can simply return that string (pass-by-value). + Otherwise, + the most efficient and flexible way to return a string is + to assign your result into a non-const reference parameter. + Don't bother to create a sharable string from scratch with your generated result. +

+

+ Why? + The two things you want to minimize in string manipulation are, + in order of importance, + heap allocation, and + moving characters around. +

+
+
+
+
+  /* What is the best way to return a string? */
+
+class foo
+  {
+    public:
+      // ...
+      void GetShortName( nsAString& aResult ) const;
+      nsCommonString GetFullName() const;
+      
+    private:
+      nsCommonString    mFullName;
+
+      const PRUnichar*  mShortName;

+    aResult = DependentString(mShortName, mShortNameLength);
+  }
+
+
+
+ + +
+ How do I printf a string, e.g., for debugging. +
+
+ If your string is already narrow, you just have to worry about making it flat, and then getting a pointer. +
+
+ If your string happens to be wide, + you'll need to convert it before you can printf something reasonable. + If it's just for debugging, + you probably wouldn't care if something odd was printed in the case of a Unicode character that didn't have + an ASCII equivalent. (If you have a UTF-8 terminal, the result is + perfectly legible and nothing odd is printed.) + The simplest thing in this case is to make a temporary conversion using NS_ConvertUTF16toUTF8. + The result is conveniently flat already, so getting the pointer is simple. + Remember not to hold onto the pointer you get out of this beyond the lifetime of temporary. +
+
+
+
+  /* How do I |printf| a string? */
+
+
+void PrintSomeStrings( const nsAString& aString, const PRUnichar* aKey, const nsACString& aCString )
+  {
+      // |printf|ing a narrow string is easy
+    printf("%s\n", PromiseFlatCString(aCString).get());     // GOOD
+
+      // the simplest way to get a |printf|-able |const char*| out of a string
+    printf("%s\n", NS_ConvertUTF16toUTF8(aKey).get());       // GOOD
+
+      // works just as well with an formal wide string type...
+    printf("%s\n", NS_ConvertUTF16toUTF8(aString).get());
+
+
+      // But don't hold onto the pointer longer than the lifetime of the temporary!
+    const char* cstring = NS_ConvertUTF16toUTF8(aKey).get(); // BAD! |cstring| is dangling
+    printf("%s\n", cstring);

Encoding Wars + +

This message is all about strings and the various encodings that might +be used to interpret their contents, the ramifications of that, and +where we're heading. The point of this message is to say what we're +currently thinking, and get feedback. I apologize in advance for the +rambling, and for the fact that this message may accidentally mix +discussion of how things are and how they will be. + +

There are many different possible encodings. Three in common use in +the Mozilla source base are: ASCII, UTF-16, and UTF-8. In ASCII, every + +character fits in 7-bits and is typically stored in an 8-bit byte. We +usually represent ASCII strings with nsCStrings, nsXPIDLCStrings, +or char string literals. In UTF-16, characters occupy one 16-bit code unit ( + +BMPcharacters) +or two 16-bit code units +( +non-BMP characters). +We usually represent UTF-16 strings as nsStrings, etc., i.e., two-byte +or `wide' strings. UTF-8 is a multi-byte encoding. A character might +occupy one, two, three, or four bytes. It is easiest to store and +manipulate such a string within a single-byte or `narrow' string +implementation. + +

None of our current string implementations know the encoding of the +data they hold at any given moment. An nsCString might legitimately +hold data encoded in ASCII, UTF-8 or even EBCDIC for that matter. + +

Operations that convert from one encoding to another, or operations +that are encoding sensitive (e.g., to_upper), rightly belong in +i18n. The fact that our current string interfaces automatically and +implicitly convert between wide and narrow strings is actually the +source of many errors in two particular categories: (1) unintended +extra work, (2) mistaken re-encoding, e.g., accidentally `converting' +a UTF-8 string to UTF-16 by pretending the UTF-8 string is ASCII and then +padding with '\0's. + +

We've known these were bad for a long time, and have been trying to +find the right way to fix them. The current thinking is to just byte +the bullet and eliminate implicit conversions. That has interesting +ramifications. + +

+
+void foo( const nsString&  aUTF16string );
+
+foo("hello"); // works!  constructs a temporary |nsString| by
+              // converting the ASCII literal with padding.
+              // Note: this requires an allocation
+
+
+ +

Though we've always hated this form since it requires a heap +allocation. In current code, we recommend + +

+
+foo( nsAutoString("hello") );
+
+
+ +

which still copy/converts, but at least it probably doesn't need to do +a heap allocation. In the best of all worlds, no conversion, copying, +or allocation would be necessary. To do that, you would need to be +able to directly specify a UTF-16 string, e.g., with the L"hello" +notation, and wrap that in an interface that just held a pointer. +E.g., something like + +

+
+void foo( const nsAReadableString&  aUTF16string );
+
+foo( nsLiteralString(L"hello") );
+
+
+ +

There are problems with this example, however. The L notation +specifically makes objects that are arrays of wchar_t, which under +GCC is a 4-byte element. This leads to incompatibility with JS, and +the annoyance of possibly bloated storage (I'm sort of minimizing the +situation here. It's worse that I make it sound). More about tricks +to get around this in a bit, but first, let me talk about what to do +in the meantime while we're just getting rid of implicit constructors. + Initially to get around this problem (what problem? The problem that +foo("hello") stopped compiling on my machine when I threw the +switch) I made a routine called NS_ConvertToString which looked like +this + +

+
+inline
+nsAutoString
+NS_ConvertToString( const char* anASCIIstring )
+  {
+    nsAutoString aUCS2string;
+    aUCS2string.AssignWithConversion(anASCIIstring);
+    return aUCS2string;
+  }
+
+
+ +

Which lets me write + +

+
+foo( NS_ConvertToString("hello") );
+
+
+ +

This was OK, but in discussion there were concerns about performance +on machines that didn't inline well, and issues about naming. In +that meeting we came up with an alternate naming strategy that we +think has room for growth and an implementation more likely to be +efficient on every platform. The implementation is to define a new +class that derives from nsAutoString, but allows construction from a +char* + +

+
+class NS_ConvertASCIItoUTF16 : public nsAutoString
+  {
+    public:
+      NS_ConvertASCIItoUTF16( const char* );
+      // ...
+  };
+
+
+ +

Which gives identical (though renamed) notation for calling foo: + +

+
+foo( NS_ConvertASCIItoUTF16("hello") );
+
+
+ +

It looks like a function call to an explicit encoding conversion. It +acts like a function call to an explicit encoding conversion. It is +a function call to an explicit encoding conversion. We think that +this naming pattern has room for growth. In the meeting, we concluded +that the best representation for encoding conversions is a family of +functions, and NS_ConvertASCIItoUTF16 fits right in. We think that +XPCOM probably can't live without the ASCII to UTF-16 conversion (though +as explicit as possible) but that all others rightly belong in i18n +land. + +

You can probably deduce from the clues in NS_ConvertToString, above, +that constructors weren't the only thing that became explicit. +Assignment, appending, comparison, et al, got renamed so that when +assigning, appending, or comparing to a value in a different encoding +the `WithConversion' form must be used. E.g., + +

+
+nsString aUTF16string;
+nsCString anASCIIstring;
+// ...
+
+aUTF16string += anASCIIstring;  // Currently legal, but not for long
+aUTF16string.Append(anASCIIstring); // same
+
+aUTF16string.AppendWithConversion(anASCIIstring); // the new way
+
+if ( aUTF16string == anASCIIstring ) // Sorry, this is going away too
+  // ...
+
+if ( aUTF16string.EqualsWithConversion(anASCIIstring) )
+  // ...
+
+
+ +

Yes, it's long and annoying. Just like the extra work you were +implicitly asking to have done, perhaps incorrectly. There are other +reasons to rename these functions. When nsString and nsCString +defined a ton of, e.g., Appends each there was no problem, because +nobody wanted to override Append. Now, with strings inheriting from +abstract base classes we immediately run into the problem that +overriding and overloading don't mix very well in C++. Because of a +feature of C++ called name hiding, it is problematic to override only +a single signature of a name overloaded in a base class. The base +nsAWritableString provides several Appends, all for objects of +(hopefully) the same encoding. nsString can't easily add a bunch of +new Appends (the converting ones) without running face first into +the name hiding problem. The discussion of the fix for this is mostly +unrelated to encoding issues, so I'll defer it to another post. + +

In hindsight, after the meeting, it seemed clear that all the +`WithConversion' forms would be better named + +

+
+xxxConvertingASCIItoUTF16
+xxxConvertingUTF16toASCII
+
+
+ +

however, the real goal (probably) is to move most such conversions +into i18n. Just bringing attention to the previously implicit +conversions is a good first step. Renaming these conversions as just +suggested is probably the right thing to do, though it sort of +validates them, which I'm not sure we really want. This is a decision +we need to discuss further. + +

Now, back to the string literal problem above. One possible solution +is to use a macro. Imagine + +

+
+NS_LITERAL_STRING("Hello")
+
+
+ +

which on a machine where the L trick works, turns into + +

+
+nsLiteralString(L"Hello")
+
+
+ +

but on a machine where there is trouble, turns into something less +appealing, but more likely to work, like + +

+
+NS_ConvertASCIItoUTF16("Hello")
+
+
+ +

Another solution is to add a compilation step that fixes L strings +on bad platforms to be non-L strings, but padded with \0s. E.g., +L"Hello" gets preprocessed into "\000H\000e\000l\000l\000o\000". +This solution is more annoying to the developer, where the prior +solution is more annoying during the runtime. + +

Before we go to too much trouble on this specific feature, we will +probably want to do more measurement to see just how much and how +often we are converting constant literal strings, and why. + + +

I'm currently ripping through the tree fixing things to use the +`WithConversion' forms where appropriate. I was also converting +things to use NS_ConvertToString where appropriate; unless I get +talked out of it, I want to switch midstream to +NS_ConvertASCIItoUTF16, then go back and fix up the +NS_ConvertToString instances later. I've set things up so I can +check in as I go. After all these conversions have been done, I'll be +able to throw the switch (what switch? NEW_STRING_APIS) which will +make nsString inherit from nsAWritableString, etc. and allow us to +start exploiting these other opportunities (e.g., for literal strings, +shared strings, etc. See +http://bugzilla.mozilla.org/show_bug.cgi?id=28221 for details and +reasoning.) + +

I guess I'm expecting comments on: + +

    +
  • how really annoying this whole topic is +
  • how bad L"xxx" is +
  • whether to move forward with NS_ConvertASCIItoUTF16 +
  • whether we should move to xxxConvertingASCIItoUTF16 etc instead + of `WithConverting' +
  • arguments about where encoding conversions should live +
  • arguments about whether going between 1 and 2 byte storage is an + encoding conversion +
  • questions about stuff I didn't mention or didn't explain well +
  • pointing out stuff I'm just plain wrong about, or things I forgot +
  • etc +
+ +

So as not to jumble the discussion, I'll be separately posting other +requests for comments about specific features of the design of the new +string hierarchy. + +

I hope this helps keep everybody filled in on what we're thinking and +able to point out what we're forgetting or screwing up :-) + + + + + +

+

Yes, we're aware that turning off wchar_t support makes wchar_t be +a synonym for unsigned short under Metrowerks. We know that the +current version of VC++ also makes these types equivalent. In theory, +though, the types are distinct even when they are the same size and +shape. By using real wchar_t support, we are forced to recognize +the distinction and navigate it appropriately with reinterpret_cast +(via NS_REINTERPRET_CAST). The win here is that we aren't caught by +compiler changes that suddenly make some set of compilers compliant +and therefore break our code. We will add an autoconf test that lets +UNIX compilers opt in to our string scheme when they have an +appropriately shaped wchar_t. If these happen to be compliant +compilers, all will be well. If they don't, the casts don't hurt, +because they are type correct. We are writing our code to meet the +standard as we move forward. + +

The win for us is realized by the following macros + +

+
+#ifdef HAVE_CPP_2BYTE_WCHAR_T
+  #define NS_LITERAL_STRING(s)  nsLiteralString(L##s, \
+                      (sizeof(L##s)/sizeof(wchar_t))-1)
+#else
+  #define NS_LITERAL_STRING(s)  NS_ConvertASCIItoUTF16(s, \
+                       sizeof(s)-1)
+#endif
+
+
+ +

An nsLiteralString points directly to the literal characters. No +copying, no conversion, and the length calculation happens at compile +time. This has turned out to be as large a savings as 15% of code +space and 8% of data space, net, in our string test harness It's +faster as well, again by eliminating the copying, conversion, and +length calculation. We don't know yet what those numbers translate +into in our real code base, but we have high hopes. + +

I don't want to be in the position to ask you to change your code. I +don't think it's appropriate for me to do so. The AIM application +that is your client is our client as well. They need to resolve this +difference between us in whatever way they think best. That may mean +asking you if changing your apis is the right thing to do. Or it may +mean applying the casts. Our code-base and yours, Justin, are more +like cousins. I don't think you should have to change just to conform +to us. You may think my arguments for using real wchar_t have +merit, and adopt similar usage just because you agree; but I think the +only obligation you have is to follow the technical solution you think +is right for your code. + +

If you decide to make this api change, it will mean shipping a new +binary (on Mac) for your library to clients who want to switch over to +the new api (since the name mangling will be different, and therefore, +the link requirements will change). + +

It is ``EqualsWithConversion'' because it admits the possibility of an +encoding specific transformation, in this case to provide +case-insensitive comparison.

since an nsString is a sequence of 2-byte wide characters, and the +routines that implicitly convert 1-byte sequences (like the literal +sequence you specified, "http:...") are now gone. + +

+ +

SetString was a synonym for Assign or assignment with +operator=(), it too went away. The equivalent is the second +example I gave above, that is, the one with AssignWithConversion. + +

Assign still exists. AssignWithConversion takes on that +functionality for assignments that require encoding transformations +(e.g., from ASCII to UTF16). SetString is gone, since it was always +a synonym for Assign. + +

What would you prefer? That extracting a character not in the string +always return CharT(0)? Can't do it for two reasons: (1) 0 may be +a valid character in a particular encoding, so it can't be used in +general as a ``no character at that position'' marker; and (2) I can't +control what an individual string implementation does when asked to +get an out-of-bounds fragment, it's explicitly undefined. That means +the result of CharAt is explicitly undefined for indexes outside the +defined contents of the string. As a debugging convenience, I have +made this assert, but it has always been the case that retrieving such +a character had undefined results ... even in [the old] code. + +

OK, you might say, well at least let me ask for a character that is +only off the end by one. E.g., Last of an empty string. Reason (1) +from above still applies. How bad is it to say, for the case you gave + +

+
+PRBool needsDelim = PR_FALSE;

In general, you probably want to opt out of a whole lot of work when +the source string is empty. It is slightly less convenient, but it +doesn't tie us to a bunch of implementation specific mojo. + + +

+ +

This is an annoying property of auto strings, e.g., that they always +have an allocated buffer. I'm happy to fix this bug, however, be +aware that GetUnicode and GetBuffer are artifacts of [the old] +implementation that we don't want to support. They are not part of +the abstract interface.

People who require a +contiguous hunk of characters in the future, and are unwilling to +switch over to chunky-iterators, may be forced to copy the string to +their own buffer. There will be an implementation of narrow character +string that guarantees contiguous allocation and a zero-terminator, +much as nsCString does now, for compatibility with platform uses, +but this won't be the default string class. + + + + + +

You got it right... it's nsWritingIterator for whichever +character type you care about, either char or PRUnichar. You +_can_ use this iterator like a character pointer ... that is, you can +dereference it, assign into its dereference, etc. It is more +efficient, though, to directly address a particular range of +characters around where it points by asking it for its actual +character pointer with get, and knowing that there are +size_forward() characters available ahead of that pointer and +size_backward() characters available behind it. After examining +those characters by hand, you can advance the iterator beyond the +characters you have examined (and possibly into the next chunk, should +one exist) by adding into it (with +=) the count of the characters you +have processed. + +

Here are three examples of running through a string and modifying some +of the characters in it. All use nsWritingIterators. + + +

+
+  // inefficient, but works in a pinch:
+  //  iterators can hide all details of chunks by acting like

+nsWritingIterator<PRUnichar> done_with_string = S.EndWriting();
+
+  // for each character in the string |S|
+while ( s != done_with_string )
+  {
+      // if the character is lower case, capitalize it
+    if ( 'a' <= *s && *s <= 'z' )
+      *s = *s -'a' + 'A';
+  }
+
+
+
+
+  // efficient
+  //  iterators provide a mechanism by which you can process
+  //  a chunk-at-a-time
+
+nsWritingIterator<PRUnichar> iter = S.BeginWriting();
+nsWritingIterator<PRUnichar> done_with_string = S.EndWriting();
+
+  // for each chunk of the string
+while ( iter != done_with_string )
+  {
+    size_t N = iter.size_forward();  // # of chars in this chunk
+    PRUnichar* s = iter.get();
+    PRUnichar* done_with_chunk = s + N;
+
+      // for each character in this chunk
+    for ( ; s < done_with_chunk; ++s )
+      {
+         // if the character is lower case, capitalize it
+       if ( 'a' <= *s && *s <= 'z' )
+          *s = *s - 'a' + 'A';
+      } 
+
+      // advance the iterator past characters

+    s += N;
+  }
+
+
+
+  // elegant

I'll explain things in a little more detail than you need, then so +that some of the stuff you see in these headers will make more sense. +I'll also answer your questions out of order. + +

First: the string hierarchy looks like this + +http://ScottCollins.net/Journal/discussion/string_hierarchy.gif + +

The two most important headers are: + +http://lxr.mozilla.org/seamonkey/source/xpcom/ds/nsAReadableString.h +http://lxr.mozilla.org/seamonkey/source/xpcom/ds/nsAWritableString.h + +

These abstract classes, nsAReadable[C]String, and +nsAWritable[C]String are typically what you will want to use in the +interfaces of new code. If you write a piece of code that takes a +string for input, consider, e.g., + +

+
+void consumes_a_string( const nsAReadableString&  aInput );
+
+
+ +

If you write a piece of code that modifies a string, consider + +

+
+void modifies_a_string( nsAWritableString&  aResult );
+
+
+ + +

When creating your own classes, member strings will typically be +nsStrings. When you can't avoid creating a short string that you +need only temporarily during a function, you will typically use +nsAutoString. When someone passes you a raw pointer, or a raw +pointer and a length, representing a buffer of characters that you may +examine, but won't own, you can treat it like a string by wrapping it +in an nsLiteralString, e.g., + +

You will use nsLiteralString around quoted constant strings as well, +though typically through the NS_LITERAL_STRING macro, to avoid doing +a length calculation + +

+
+NS_LITERAL_STRING("x")
+
+
+ +

expands to + +

+
+nsLiteralString(L"x", (sizeof(L"x")/sizeof(PRUnichar) - 1))
+
+
+ +

if L notation works as needed on your platform. + +Those are the basics. Now onto your questions: + + +

+ + +

L"abc " makes a an object that is a const wchar_t[5], and none of +the string code knows about wchar_t. The main reason is that +wchar_t is not necessarily the right size (it can be 4 bytes under +gcc). If you wrap these constant expressions in NS_LITERAL_STRING, +as described above, you should get the right thing, e.g., + +

+
+str1 += NS_LITERAL_STRING("abc ") + str2 + NS_LITERAL_STRING("def");
+
+
+ + + + +

This one, I have a quick and easy explanation for. If function was +declared like this + +

+
+function( const nsAReadableString&  )
+
+
+ +

then, no problem, since a nsPromiseConcatenation (which was the +result of adding those two things together) is a readable string. +No other objects need to be created; no copying needs to be performed. + +

In all cases, we want the creation of nsStrings et al, to be +explicit, since creation is unbelievably expensive, requiring heap +allocation, locks, copying, etc. + +

I hope this answers both your posts, + + + + + +

Unfortunately, NS_LITERAL_STRINGs definition is not particularly +amenable to this use. Instead, you would have to say something like +this: + +

+
+const nsAReadableString&
+foo()
+  {
+#ifdef HAVE_CPP_2BYTE_WCHAR_T

+        static_foo.AssignWithConversion("x", 1);
+        initialized = PR_TRUE;
+      }
+#endif
+    return static_foo;
+  }
+
+
+ + + + +

I don't know what errors you are getting; but it probably doesn't work +because a reference isn't an assignable type. This is just a guess. +You may need to use + +

+
+map
+
+
+ +

If you actually want the map to manage ownership of the keys, then +you'll want to use a concrete type, e.g., + +

+
+map
+
+
+ +

or perhaps + +

+
+map
+
+
+ +

Or maybe there's something else wrong. Send me the error messages. +If you end up using a pointer, then of course you'll have to supply a +comparison function to the map template. You won't be satisfied +with the default comparison of pointers :-) Sorry I couldn't answer +this one more completely. + + +

+ +

The problem with this scenario is that an nsAReadableString doesn't +promise that all its data is contiguous, nor that it is +zero-terminated, which is what I suspect you want in this case. If +the function you want to call can take {pointer, length} tuples, and +can consume the string in hunks without zero termination ... then you +can use copy_string to pump the string into your function, see + + http://ScottCollins.net/Journal/discussion/string_iterators.html + +

If not, and you absolutely have to have a contiguous zero-terminated +buffer, then there is a new facility (part of the DOMAPI branch) that +does what you need. It's not checked in on the trunk; it should +be in early next week. It is nsPromiseFlatString. This class +promises a contiguous zero-terminated buffer; and has an operator +PRUnichar* to produce a pointer to that buffer automatically. If the +underlying class is one that happens to be a single fragment and +zero-terminated, then, like nsPromiseSubstring and +nsPromiseConcatenation, this class merely holds a reference into the +original data. If, however, the underlying string is multi-fragment +or not zero-terminated, then nsPromiseFlatString allocates a +contiguous buffer of appropriate size and copies the fragmented string +data to it. So given + +

+
+void ReadBuffer( PRUnichar* );
+
+
+ +

You can call this as efficiently as possible with an arbitrary string +like so + +

+
+ReadBuffer( nsPromiseFlatString(aString) );
+
+
+ + +

If the function you are calling needs to take ownership of the buffer +you hand it, then you will probably call ToNewUnicode like so + +

+
+void ConsumeBuffer( PRUnichar* );
+
+ConsumeBuffer( ToNewUnicode(aString) );
+
+
+ +

The global function ToNewUnicode is declared in "nsReadableUtils.h", +and was only recently added to the build. It is currently being used +in the DOMAPI branch. It is part of the build, but the file +"dlldeps.c" in XPCOM may need to be modified to ensure it is exported +on your platform if you are building the tip. + +Needless to say, you want to avoid functions that require bare +pointers for several reasons: (a) they typically assume +zero-termination, which is not guaranteed by the normal encodings; (b) +they require contiguous allocation, which may not be possible; (c) +they scan for the end of the string, at linear cost (if the encoding +makes it possible at all), when the length could be known in advance. +If you have to do it, the above mechanisms work, but be aware of the +cost and the potential need to copy. + + +

+ +

nsAReadableString is an abstract type. So you can't have a concrete +instance of it. All strings in the hierarchy are readable strings. +If you just want a reference to a readable string, you can say, e.g., + +

+
+struct foo
+  {
+    const nsAReadableString&  mString;
+    // ...
+
+    foo( const nsAReadableString&  aString ) : mString(aString) { }
+  };
+
+
+ +

...similarly with pointers; but I suspect you are looking for +something more concrete. An nsString is a nsAReadableString, and +is the typical thing you want as a member variable. An nsAutoString +is also an nsAReadableString and is typically what you would use for +a short (in length) temporary (in lifetime) local variable, as I +mentioned in my previous post. + + +

+ +

Yes, though remember, an nsLiteralString assumes the lifetime of the +underlying data is under someone else's control. If the called +function gives you a buffer that you need to delete, you will have +to manage that yourself. Currently, people often use nsXPIDLString +to handle that. XPIDL strings are not part of the hierarchy. They +are only used as a sort of string-auto_ptr. However, I'm +integrating their functionality into nsString. There is no problem +in wrapping the same pointer in both as two separate local variables, +one to give you the readable interface, and one to manage the +lifetime. + +

If it's OK with you, I'd like to post this reply (including your +quoted questions) to n.p.m.xpcom and also put a copy near the string +iterator discussion I provided a link to above, so that other people +with similar questions can see these answers. + +

Hope this helps, + + + + + +

The general case is that a string does not promise to have contiguous +data. A specific case is that, for some implementations, it does. +You couldn't do it the other way around, because a segmented string +couldn't satisfy all the promises of a flat string. However, through +the use of chunky iterators, operating on strings that happen to be +flat is very efficient. In fact, nsPromiseFlatString is trivial in +the non-segmented case. In addition, I'll be adding an abstract flat +class into the hierarchy, which will present additional interface ... +in your local routines where you actually have declared a concrete +string instance that happens to be flat, the compiler will give you +the benefit of using the flat specific routines (e.g., a substring +object over a flat string is simpler than the general purpose +substring). I need to be cautious about this, though, since I don't +automatically want people propagating the flat type through their +interfaces.

A specific string implementation could promise this, but in general, a +writable could not. After all, a writable doesn't even guarantee +contiguous storage. To some degree, this is what +nsPromiseFlatString is for. However, this is a readable promise +only. It will also be the case that ns[C]Strings, in the very near +future will be able to just assume ownership of an arbitrary buffer +allocated on the free store with the XPCOM allocators ... getting one +to give up its buffer, on the other hand, presents some problems. Do +you have a lot of places where the system writes into your string +buffer space? Or do you have a lot of system routines that return you +new buffers? I can imagine using nsPromiseFlatString for this, but +what happens when the OS alters the underlying data?

ToInteger is actually a bad interface. It's only good if your +entire string is the number; this encourages you to edit your string +until it is one, or perhaps copy the numeric part to another string. +Better if you just sscanf a string (don't know if I can provide +that in the general case, but I'm thinking about it), or else use +regular C++ extractors (which wouldn't be too hard for me to +provide), or else I could give you a ToInteger that works on a pair +of iterators, extracting the integer from the digits between them. + +> +> 5) There should be a global define for an interface to a readonly +> empty string. + +

You can see from the line of code that you're on, that this should +have been fine. nsMemory::Alloc would be asked to allocate a 1 byte +object. But it failed trying to allocate that. Which suggests that +the allocator was busy and non-reentrant and the debugger tried to +misuse it. Yes? + +

Of course, this doesn't solve your problem. Perhaps we need to go +back to the idea of a function that returns a pointer to the first +hunk of the string. + +

+
+const char*
+debug_string( const nsAReadableCString& aCString )
+  {
+    nsReadingIterator<char> iter;
+    aCString.BeginReading(iter);
+    return aCString.IsEmpty() ? "" : iter.get();
+  }
+
+
+ +

This code should work regardless of what the allocator is doing. The +downsides are (a) it only returns the first hunk of the string, in the +case of a multi-fragment string; and (b) that hunk might not be +zero-terminated. + +

Hope this helps, + + + + + +

These are + abstract classes (interfaces), containing only virtual functions + corresponding to the FROZEN nsA[C]String classes. They exist to provide + the new non-abstract nsA[C]String classes with a mechanism to maintain + backwards binary compatability. + + From a binary point-of-view, the new nsA[C]String classes appear to have a + vtable pointer to the vtable of nsObsoleteA[C]StringThunk. + nsObsoleteA[C]StringThunk is a subclass of nsObsoleteA[C]String that serves + as a simple bridge between the virtual functions that make up the FROZEN + nsA[C]String contract and the new ns[C]Substring, which is now our only + subclass of nsA[C]String. + + The methods on the new nsA[C]String are now all non-virtual. This reduces + codesize at the callsite, and reduces the number of memory dereferences and + jumps required to invoke a method on nsA[C]String. The result is improved + performance and reduced codesize. However, to maintain binary + compatibility, each method on nsA[C]String must check the value of its + vtable to determine if it corresponds to the built-in implementation of + nsObsoleteA[C]String (i.e., the address of the canonical vtable). If it + does, then the vtable can be ignored, and the nsA[C]String object (i.e., + |this|) can be cast to ns[C]Substring directly. In which case, the + nsA[C]String methods can be satisfied by invoking the corresponding methods + directly on ns[C]Substring. If the vtable address does not correspond to + the built-in implementation, then the virtual functions on + nsObsoleteA[C]String must be invoked instead. + + So, if a nsA[C]String reference corresponds to an external implementation + (such as the old nsEmbed[C]String that shipped with previous versions of + Mozilla), then methods invoked on that nsA[C]String will still act like + virtual function calls. This ensures binary compatibility while avoiding + virtual function calls in most cases. + + Finally, nsObsoleteA[C]String (i.e., the FROZEN nsA[C]String vtable) is + now a DEPRECATED interface. See nsStringAPI.h and nsEmbedString.h for + the new preferred way to access nsA[C]String references in an external + component or Gecko embedding application. + */ + +#ifndef nsStringFwd_h___ +#include "nsStringFwd.h" +#endif + +#ifndef nscore_h___ +#include "nscore.h" +#endif + + // declare nsObsoleteAString +#include "string-template-def-unichar.h" +#include "nsTObsoleteAString.h" +#include "string-template-undef.h" + + // declare nsObsoleteACString +#include "string-template-def-char.h" +#include "nsTObsoleteAString.h" +#include "string-template-undef.h" + +#endif // !defined(nsObsoleteAString_h___) diff --git a/src/libs/xpcom18a4/xpcom/string/public/nsPrintfCString.h b/src/libs/xpcom18a4/xpcom/string/public/nsPrintfCString.h new file mode 100644 index 00000000..3f3d04d3 --- /dev/null +++ b/src/libs/xpcom18a4/xpcom/string/public/nsPrintfCString.h @@ -0,0 +1,87 @@ +/* -*- Mode: C++; tab-width: 2; indent-tabs-mode: nil; c-basic-offset: 2 -*- */ +/* ***** BEGIN LICENSE BLOCK ***** + * Version: MPL 1.1/GPL 2.0/LGPL 2.1 + * + * The contents of this file are subject to the Mozilla Public License Version + * 1.1 (the "License"); you may not use this file except in compliance with + * the License.

Write your own code to + * use |nsA[C]String&|s for parameters. Write your string proccessing + * algorithms to exploit iterators. If you do this, you will benefit from + * being able to chain operations without copying or allocating and your code + * will be significantly more efficient.

But a function that + * takes a character pointer always has the potential to force allocation and + * copying. + * + * + * How to use it: + * + * A |nsPromiseFlat[C]String| doesn't necessarily own the characters it + * promises. You must never use it to promise characters out of a string + * with a shorter lifespan. The typical use will be something like this: + * + * SomeOSFunction( PromiseFlatCString(aCString).get() ); // GOOD + * + * Here's a BAD use: + * + * const char* buffer = PromiseFlatCString(aCString).get(); + * SomeOSFunction(buffer); // BAD!! |buffer| is a dangling pointer + * + * The only way to make one is with the function |PromiseFlat[C]String|, + * which produce a |const| instance. ``What if I need to keep a promise + * around for a little while?'' you might ask. In that case, you can keep a + * reference, like so + * + * const nsPromiseFlatString& flat = PromiseFlatString(aString); + * // this reference holds the anonymous temporary alive, but remember, + * // it must _still_ have a lifetime shorter than that of |aString| + * + * SomeOSFunction(flat.get()); + * SomeOtherOSFunction(flat.get()); + * + * + * How does it work? + * + * A |nsPromiseFlat[C]String| is just a wrapper for another string.

All event structures you +define must include a PLEvent struct as their first field: + + typedef struct MyEventType { + PLEvent e; + // arguments follow... + int x; + char* y; + } MyEventType; + +It is also essential that you establish a model of ownership for each +argument passed in an event record, i.e. whether particular arguments +will be deleted by the event destruction callback, or whether they +only loaned to the event handler callback, and guaranteed to persist +until the time at which the handler is called. + +Sending Events +-------------- + +Events are initialized by PL_InitEvent and can be sent via +PL_PostEvent or PL_PostSynchronousEvent. Events can also have an +owner. The owner of an event can revoke all the events in a given +event-queue by calling PL_RevokeEvents. An owner might want +to do this if, for instance, it is being destroyed, and handling the +events after the owner's destruction would cause an error (e.g. an +MWContext). + +Since the act of initializing and posting an event must be coordinated +with it's possible revocation, it is essential that the event-queue's +monitor be entered surrounding the code that constructs, initializes +and posts the event: + + void postMyEvent(MyOwner* owner, int x, char* y) + { + MyEventType* event; + + PL_ENTER_EVENT_QUEUE_MONITOR(myQueue); + + // construct + event = PR_NEW(MyEventType); + if (event == NULL) goto done; + + // initialize + PL_InitEvent(event, owner, + (PLHandleEventProc)handleMyEvent, + (PLDestroyEventProc)destroyMyEvent); + event->x = x; + event->y = strdup(y); + + // post + PL_PostEvent(myQueue, &event->e); + + done: + PL_EXIT_EVENT_QUEUE_MONITOR(myQueue); + } + +If you don't call PL_InitEvent and PL_PostEvent within the +event-queue's monitor, you'll get a big red assert. + +Handling Events +--------------- + +To handle an event you must write a callback that is passed the event +record you defined containing the event's arguments: + + void* handleMyEvent(MyEventType* event) + { + doit(event->x, event->y); + return NULL; // you could return a value for a sync event + } + +Similarly for the destruction callback: + + void destroyMyEvent(MyEventType* event) + { + free(event->y); // created by strdup + free(event); + } + +Processing Events in Your Event Loop +------------------------------------ + +If your main loop only processes events delivered to the event queue, +things are rather simple. You just get the next event (which may +block), and then handle it: + + while (1) { + event = PL_GetEvent(myQueue); + PL_HandleEvent(event); + } + +However, if other things must be waited on, you'll need to obtain a +file-descriptor that represents your event queue, and hand it to select: + + fd = PL_GetEventQueueSelectFD(myQueue); + ...add fd to select set... + while (select(...)) { + if (...fd...) { + PL_ProcessPendingEvents(myQueue); + } + ... + } + +Of course, with Motif and Windows it's more complicated than that, and +on Mac it's completely different, but you get the picture. + +Revoking Events +--------------- +If at any time an owner of events is about to be destroyed, you must +take steps to ensure that no one tries to use the event queue after +the owner is gone (or a crash may result). You can do this by either +processing all the events in the queue before destroying the owner: + + { + ... + PL_ENTER_EVENT_QUEUE_MONITOR(myQueue); + PL_ProcessPendingEvents(myQueue); + DestroyMyOwner(owner); + PL_EXIT_EVENT_QUEUE_MONITOR(myQueue); + ... + } + +or by revoking the events that are in the queue for that owner. This +removes them from the queue and calls their destruction callback: + + { + ... + PL_ENTER_EVENT_QUEUE_MONITOR(myQueue); + PL_RevokeEvents(myQueue, owner); + DestroyMyOwner(owner); + PL_EXIT_EVENT_QUEUE_MONITOR(myQueue); + ... + } + +In either case it is essential that you be in the event-queue's monitor +to ensure that all events are removed from the queue for that owner, +and to ensure that no more events will be delivered for that owner. +**********************************************************************/ + +#ifndef plevent_h___ +#define plevent_h___ + +#include "prtypes.h" +#include "prclist.h" +#include "prthread.h" +#include "prlock.h" +#include "prcvar.h" +#include "prmon.h" + +/* For HWND */ +#if defined(XP_WIN32) +#include +#elif defined(XP_OS2) +#define INCL_DOSMISC +#define INCL_DOSPROCESS +#define INCL_DOSERRORS +#include +#endif + +#ifdef VBOX_WITH_XPCOM_NAMESPACE_CLEANUP +#define PL_DestroyEvent VBoxNsplPL_DestroyEvent +#define PL_HandleEvent VBoxNsplPL_HandleEvent +#define PL_InitEvent VBoxNsplPL_InitEvent +#define PL_CreateEventQueue VBoxNsplPL_CreateEventQueue +#define PL_CreateMonitoredEventQueue VBoxNsplPL_CreateMonitoredEventQueue +#define PL_CreateNativeEventQueue VBoxNsplPL_CreateNativeEventQueue +#define PL_DequeueEvent VBoxNsplPL_DequeueEvent +#define PL_DestroyEventQueue VBoxNsplPL_DestroyEventQueue +#define PL_EventAvailable VBoxNsplPL_EventAvailable +#define PL_EventLoop VBoxNsplPL_EventLoop +#define PL_GetEvent VBoxNsplPL_GetEvent +#define PL_GetEventOwner VBoxNsplPL_GetEventOwner +#define PL_GetEventQueueMonitor VBoxNsplPL_GetEventQueueMonitor +#define PL_GetEventQueueSelectFD VBoxNsplPL_GetEventQueueSelectFD +#define PL_MapEvents VBoxNsplPL_MapEvents +#define PL_PostEvent VBoxNsplPL_PostEvent +#define PL_PostSynchronousEvent VBoxNsplPL_PostSynchronousEvent +#define PL_ProcessEventsBeforeID VBoxNsplPL_ProcessEventsBeforeID +#define PL_ProcessPendingEvents VBoxNsplPL_ProcessPendingEvents +#define PL_RegisterEventIDFunc VBoxNsplPL_RegisterEventIDFunc +#define PL_RevokeEvents VBoxNsplPL_RevokeEvents +#define PL_UnregisterEventIDFunc VBoxNsplPL_UnregisterEventIDFunc +#define PL_WaitForEvent VBoxNsplPL_WaitForEvent +#define PL_IsQueueNative VBoxNsplPL_IsQueueNative +#define PL_IsQueueOnCurrentThread VBoxNsplPL_IsQueueOnCurrentThread +#define PL_FavorPerformanceHint VBoxNsplPL_FavorPerformanceHint +#endif /* VBOX_WITH_XPCOM_NAMESPACE_CLEANUP */ + +PR_BEGIN_EXTERN_C + +/* Typedefs */ + +typedef struct PLEvent PLEvent; +typedef struct PLEventQueue PLEventQueue; + +/******************************************************************************* + * Event Queue Operations + ******************************************************************************/ + +/* +** Creates a new event queue.
