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 + + For a longer but slightly out of date high-level description, see + http://gee.cs.oswego.edu/dl/html/malloc.html + + You may already by default be using a c library containing a malloc + that is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.

This malloc does NOT call MORECORE(0) + until at least one call with positive arguments is made, so + the initial value returned is not important. + + * Even though consecutive calls to MORECORE need not return contiguous + addresses, it must be OK for malloc'ed chunks to span multiple + regions in those cases where they do happen to be contiguous. + + * MORECORE need not handle negative arguments -- it may instead + just return MORECORE_FAILURE when given negative arguments. + Negative arguments are always multiples of pagesize.

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: ");
+}

+
+ 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 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;

+  }
+
+
+
+ + +
+ 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.
