License Grants and Conditions +-------------------------------- + +2.1. Grants + +Each Contributor hereby grants You a world-wide, royalty-free, +non-exclusive license: + +(a) under intellectual property rights (other than patent or trademark) + Licensable by such Contributor to use, reproduce, make available, + modify, display, perform, distribute, and otherwise exploit its + Contributions, either on an unmodified basis, with Modifications, or + as part of a Larger Work; and + +(b) under Patent Claims of such Contributor to make, use, sell, offer + for sale, have made, import, and otherwise transfer either its + Contributions or its Contributor Version. + +2.2. Effective Date + +The licenses granted in Section 2.1 with respect to any Contribution +become effective for each Contribution on the date the Contributor first +distributes such Contribution. + +2.3. Limitations on Grant Scope + +The licenses granted in this Section 2 are the only rights granted under +this License. No additional rights or licenses will be implied from the +distribution or licensing of Covered Software under this License. +Notwithstanding Section 2.1(b) above, no patent license is granted by a +Contributor: + +(a) for any code that a Contributor has removed from Covered Software; + or + +(b) for infringements caused by: (i) Your and any other third party's + modifications of Covered Software, or (ii) the combination of its + Contributions with other software (except as part of its Contributor + Version); or + +(c) under Patent Claims infringed by Covered Software in the absence of + its Contributions. + +This License does not grant any rights in the trademarks, service marks, +or logos of any Contributor (except as may be necessary to comply with +the notice requirements in Section 3.4). + +2.4. Subsequent Licenses + +No Contributor makes additional grants as a result of Your choice to +distribute the Covered Software under a subsequent version of this +License (see Section 10.2) or under the terms of a Secondary License (if +permitted under the terms of Section 3.3). + +2.5. Representation + +Each Contributor represents that the Contributor believes its +Contributions are its original creation(s) or it has sufficient rights +to grant the rights to its Contributions conveyed by this License. + +2.6. Fair Use + +This License is not intended to limit any rights You have under +applicable copyright doctrines of fair use, fair dealing, or other +equivalents. + +2.7. Conditions + +Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted +in Section 2.1. + +3. Responsibilities +------------------- + +3.1. Distribution of Source Form + +All distribution of Covered Software in Source Code Form, including any +Modifications that You create or to which You contribute, must be under +the terms of this License. You must inform recipients that the Source +Code Form of the Covered Software is governed by the terms of this +License, and how they can obtain a copy of this License. You may not +attempt to alter or restrict the recipients' rights in the Source Code +Form. + +3.2. Distribution of Executable Form + +If You distribute Covered Software in Executable Form then: + +(a) such Covered Software must also be made available in Source Code + Form, as described in Section 3.1, and You must inform recipients of + the Executable Form how they can obtain a copy of such Source Code + Form by reasonable means in a timely manner, at a charge no more + than the cost of distribution to the recipient; and + +(b) You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter + the recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + +You may create and distribute a Larger Work under terms of Your choice, +provided that You also comply with the requirements of this License for +the Covered Software. If the Larger Work is a combination of Covered +Software with a work governed by one or more Secondary Licenses, and the +Covered Software is not Incompatible With Secondary Licenses, this +License permits You to additionally distribute such Covered Software +under the terms of such Secondary License(s), so that the recipient of +the Larger Work may, at their option, further distribute the Covered +Software under the terms of either this License or such Secondary +License(s). + +3.4. Notices + +You may not remove or alter the substance of any license notices +(including copyright notices, patent notices, disclaimers of warranty, +or limitations of liability) contained within the Source Code Form of +the Covered Software, except that You may alter any license notices to +the extent required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + +You may choose to offer, and to charge a fee for, warranty, support, +indemnity or liability obligations to one or more recipients of Covered +Software. However, You may do so only on Your own behalf, and not on +behalf of any Contributor. You must make it absolutely clear that any +such warranty, support, indemnity, or liability obligation is offered by +You alone, and You hereby agree to indemnify every Contributor for any +liability incurred by such Contributor as a result of warranty, support, +indemnity or liability terms You offer. You may include additional +disclaimers of warranty and limitations of liability specific to any +jurisdiction. + +4. Inability to Comply Due to Statute or Regulation +--------------------------------------------------- + +If it is impossible for You to comply with any of the terms of this +License with respect to some or all of the Covered Software due to +statute, judicial order, or regulation then You must: (a) comply with +the terms of this License to the maximum extent possible; and (b) +describe the limitations and the code they affect. Such description must +be placed in a text file included with all distributions of the Covered +Software under this License. Except to the extent prohibited by statute +or regulation, such description must be sufficiently detailed for a +recipient of ordinary skill to be able to understand it. + +5. Termination +-------------- + +5.1. The rights granted under this License will terminate automatically +if You fail to comply with any of its terms. However, if You become +compliant, then the rights granted under this License from a particular +Contributor are reinstated (a) provisionally, unless and until such +Contributor explicitly and finally terminates Your grants, and (b) on an +ongoing basis, if such Contributor fails to notify You of the +non-compliance by some reasonable means prior to 60 days after You have +come back into compliance. Moreover, Your grants from a particular +Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the +first time You have received notice of non-compliance with this License +from such Contributor, and You become compliant prior to 30 days after +Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent +infringement claim (excluding declaratory judgment actions, +counter-claims, and cross-claims) alleging that a Contributor Version +directly or indirectly infringes any patent, then the rights granted to +You by any and all Contributors for the Covered Software under Section +2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all +end user license agreements (excluding distributors and resellers) which +have been validly granted by You or Your distributors under this License +prior to termination shall survive termination. + +************************************************************************ +* * +* 6. Disclaimer of Warranty * +* ------------------------- * +* * +* Covered Software is provided under this License on an "as is" * +* basis, without warranty of any kind, either expressed, implied, or * +* statutory, including, without limitation, warranties that the * +* Covered Software is free of defects, merchantable, fit for a * +* particular purpose or non-infringing. The entire risk as to the * +* quality and performance of the Covered Software is with You. * +* Should any Covered Software prove defective in any respect, You * +* (not any Contributor) assume the cost of any necessary servicing, * +* repair, or correction. This disclaimer of warranty constitutes an * +* essential part of this License. No use of any Covered Software is * +* authorized under this License except under this disclaimer. * +* * +************************************************************************ + +************************************************************************ +* * +* 7. Limitation of Liability * +* -------------------------- * +* * +* Under no circumstances and under no legal theory, whether tort * +* (including negligence), contract, or otherwise, shall any * +* Contributor, or anyone who distributes Covered Software as * +* permitted above, be liable to You for any direct, indirect, * +* special, incidental, or consequential damages of any character * +* including, without limitation, damages for lost profits, loss of * +* goodwill, work stoppage, computer failure or malfunction, or any * +* and all other commercial damages or losses, even if such party * +* shall have been informed of the possibility of such damages. This * +* limitation of liability shall not apply to liability for death or * +* personal injury resulting from such party's negligence to the * +* extent applicable law prohibits such limitation. Some * +* jurisdictions do not allow the exclusion or limitation of * +* incidental or consequential damages, so this exclusion and * +* limitation may not apply to You. * +* * +************************************************************************ + +8. Litigation +------------- + +Any litigation relating to this License may be brought only in the +courts of a jurisdiction where the defendant maintains its principal +place of business and such litigation shall be governed by laws of that +jurisdiction, without reference to its conflict-of-law provisions. +Nothing in this Section shall prevent a party's ability to bring +cross-claims or counter-claims. + +9. Miscellaneous +---------------- + +This License represents the complete agreement concerning the subject +matter hereof. If any provision of this License is held to be +unenforceable, such provision shall be reformed only to the extent +necessary to make it enforceable. Any law or regulation which provides +that the language of a contract shall be construed against the drafter +shall not be used to construe this License against a Contributor. + +10. Versions of the License +--------------------------- + +10.1. New Versions + +Mozilla Foundation is the license steward. Except as provided in Section +10.3, no one other than the license steward has the right to modify or +publish new versions of this License. Each version will be given a +distinguishing version number. + +10.2. Effect of New Versions + +You may distribute the Covered Software under the terms of the version +of the License under which You originally received the Covered Software, +or under the terms of any subsequent version published by the license +steward. + +10.3. Modified Versions + +If you create software not governed by this License, and you want to +create a new license for such software, you may create and use a +modified version of this License if you rename the license and remove +any references to the name of the license steward (except to note that +such modified license differs from this License). + +10.4. Distributing Source Code Form that is Incompatible With Secondary +Licenses + +If You choose to distribute Source Code Form that is Incompatible With +Secondary Licenses under the terms of this version of the License, the +notice described in Exhibit B of this License must be attached. + +Exhibit A - Source Code Form License Notice +------------------------------------------- + + This Source Code Form is subject to the terms of the Mozilla Public + License, v. 2.0.

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.

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.

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" + +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.

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 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. When SET_INEXACT is #defined, strtod + * also does extra computations to set the underflow and overflow + * flags when appropriate (i.e., when the result is tiny and + * inexact or when it is a numeric value rounded to +-infinity). + * #define NO_ERRNO if strtod should not assign errno = ERANGE when + * the result overflows to +-Infinity or underflows to 0. + * #define NO_HEX_FP to omit recognition of hexadecimal floating-point + * values by strtod. + * #define NO_STRTOD_BIGCOMP (on IEEE-arithmetic systems only for now) + * to disable logic for "fast" testing of very long input strings + * to strtod. This testing proceeds by initially truncating the + * input string, then if necessary comparing the whole string with + * a decimal expansion to decide close cases. This logic is only + * used for input more than STRTOD_DIGLIM digits long (default 40). + */ + +#ifndef Long +#define Long long +#endif +#ifndef ULong +typedef unsigned Long ULong; +#endif + +#ifdef DEBUG +#include "stdio.h" +#define Bug(x) {fprintf(stderr, "%s\n", x);

We remove common factors of powers of 2 from relevant + * quantities. + * 5. When converting floating-point integers less than 1e16, + * we use floating-point arithmetic rather than resorting + * to multiple-precision integers. + * 6. When asked to produce fewer than 15 digits, we first try + * to get by with floating-point arithmetic; we resort to + * multiple-precision integer arithmetic only if we cannot + * guarantee that the floating-point calculation has given + * the correctly rounded result.

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. Similarly, if you + * want something other than the system's free() to be called to + * recycle memory acquired from MALLOC, #define FREE to be the + * name of the alternate routine. (FREE or free is only called in + * pathological cases, e.g., in a dtoa call after a dtoa return in + * mode 3 with thousands of digits requested.) + * #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 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. When SET_INEXACT is #defined, strtod + * also does extra computations to set the underflow and overflow + * flags when appropriate (i.e., when the result is tiny and + * inexact or when it is a numeric value rounded to +-infinity). + * #define NO_ERRNO if strtod should not assign errno = ERANGE when + * the result overflows to +-Infinity or underflows to 0. + */ + +#ifndef Long +#define Long long +#endif +#ifndef ULong +typedef unsigned Long ULong;

We scale relevant + * quantities using O(log2(k)) rather than O(k) multiplications. + * 2. For some modes > 2 (corresponding to ecvt and fcvt), we don't + * try to generate digits strictly left to right. Instead, we + * compute with fewer bits and propagate the carry if necessary + * when rounding the final digit up. This is often faster. + * 3. Under the assumption that input will be rounded nearest, + * mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22. + * That is, we allow equality in stopping tests when the + * round-nearest rule will give the same floating-point value + * as would satisfaction of the stopping test with strict + * inequality. + * 4. We remove common factors of powers of 2 from relevant + * quantities. + * 5.

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/nsprpub/pr/src/threads/combined/prucpu.c b/nsprpub/pr/src/threads/combined/prucpu.c new file mode 100644 index 0000000000..25ffcce862 --- /dev/null +++ b/nsprpub/pr/src/threads/combined/prucpu.c @@ -0,0 +1,424 @@ +/* -*- Mode: C++; tab-width: 4; indent-tabs-mode: nil; c-basic-offset: 2 -*- */ +/* This Source Code Form is subject to the terms of the Mozilla Public + * License, v. 2.0.

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.

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.

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.

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) +#if defined(WINCE) +#include +#else +#include +#include /* for _ftime */ +#endif +#endif + +#define DEFAULT_LEAD_TIME_SECS 5 +#define DEFAULT_TOLERANCE_MSECS 500 + +static PRBool debug_mode = PR_FALSE;
