* implement a64l and l64a (legacy xsi stuff)Rich Felker2012-03-011-0/+26
|
* add all missing wchar functions except floating point parsersRich Felker2012-03-0112-0/+98
| | | | | these are mostly untested and adapted directly from corresponding byte string functions and similar.
* support null buffer argument to getcwd, auto-allocating behaviorRich Felker2012-03-011-1/+6
| | | | | | | this is a popular extension some programs depend on, and by using a temporary buffer and strdup rather than malloc prior to the syscall, i've avoided the dependency on free and thus minimized the bloat cost of supporting this feature.
* add memory.h, bogus legacy alias for string.hRich Felker2012-03-011-0/+1
|
* search internal headers firstRich Felker2012-03-011-1/+1
| | | | this is necessitated by the ugly <syscall.h> just added
* use c++-friendly initializers for pthread initializer definitionsRich Felker2012-02-291-3/+3
| | | | these will also avoid obnoxious warnings with gcc -Wbraces.
* add <syscall.h> as an alias for <sys/syscall.h>Rich Felker2012-02-291-0/+1
| | | | apparently some broken stuff (libstdc++) needs this.
* implement wcsftime functionRich Felker2012-02-281-0/+32
|
* release notes for 0.8.6 v0.8.6Rich Felker2012-02-281-0/+7
|
* fix pthread_cleanup_pop(1) crash in non-thread-capable, static-linked programsRich Felker2012-02-282-2/+2
|
* update release notes for 0.8.5 v0.8.5Rich Felker2012-02-271-0/+35

* work around "signal loses thread pointer" issue with "approach 2"Rich Felker2012-02-272-2/+8
| | | | | | | | | | | | this was discussed on the mailing list and no consensus on the preferred solution was reached, so in anticipation of a release, i'm just committing a minimally-invasive solution that avoids the problem by ensuring that multi-threaded-capable programs will always have initialized the thread pointer before any signal handler can run. in the long term we may switch to initializing the thread pointer at program start time whenever the program has the potential to access any per-thread data.
* use __attribute__((const)) on arm __pthread_self functionRich Felker2012-02-251-1/+3
|
* replace prototype for basename in string.h with non-prototype declarationRich Felker2012-02-241-1/+1
| | | | | | | | GNU programs may expect the GNU version of basename, which has a different prototype (argument is const-qualified) and prototype it themselves too. of course if they're expecting the GNU behavior for the function, they'll still run into problems, but at least this eliminates some compile-time failures.
* new attempt at working around the gcc 3 visibility bugRich Felker2012-02-243-0/+11
| | | | | since gcc is failing to generate the necessary ".hidden" directive in the output asm, generate it explicitly with an __asm__ statement...
* remove useless attribute visibility from definitionsRich Felker2012-02-242-2/+2
| | | | | | this was a failed attempt at working around the gcc 3 visibility bug affecting x86_64. subsequent patch will address it with an ugly but working hack.
* cleanup and work around visibility bug in gcc 3 that affects x86_64Rich Felker2012-02-234-12/+15
| | | | | | | | | | | | | | in gcc 3, the visibility attribute must be placed on both the declaration and on the definition. if it's omitted from the definition, the compiler fails to emit the ".hidden" directive in the assembly, and the linker will either generate textrels (if supported, such as on i386) or refuse to link (on targets where certain types of textrels are forbidden or impossible without further assumptions about memory layout, such as on x86_64). this patch also unifies the decision about when to use visibility into libc.h and makes the visibility in the utf-8 state machine tables based on libc.h rather than a duplicate test.
* fix (hopefully) PTRACE_TRACEME (command 0) argument handlingRich Felker2012-02-231-2/+2
|
* fix for previous incorrect fix of cancellation in dns lookupsRich Felker2012-02-231-3/+4
| | | | | uninitialized file descriptor was being closed on return, causing stdin to be closed in many cases.
* fix get_current_dir_name behaviorRich Felker2012-02-171-2/+6
|
* remove -std=gnu99 from musl-gcc wrapperRich Felker2012-02-171-1/+1
| | | | | while probably desirable, changing the default language variant is outside the scope of the wrapper's responsibility.
* two fixes for "make install" handling of shared libsRich Felker2012-02-171-1/+2
| | | | | | | | 1. don't try to install (and thus build) shared libs when they were disabled in config.mak 2. ensure that the path for the dynamic linker exists before attempting to install it.
* add get_current_dir_name functionRich Felker2012-02-172-0/+13
|
* add float_t and double_t to math.hRich Felker2012-02-154-0/+11
|
* fix default nameserver when resolv.conf doesn't existRich Felker2012-02-111-1/+2
|
* fix illegal goto out of cleanup context in dns lookupsRich Felker2012-02-111-3/+3
|
* small fix for new pthread cleanup stuffRich Felker2012-02-092-1/+1
| | | | | | | even if pthread_create/exit code is not linked, run flag needs to be checked and cleanup function potentially run on pop. thus, move the code to the module that's always linked when pthread_cleanup_push/pop is used.
* replace bad cancellation cleanup abi with a sane oneRich Felker2012-02-097-115/+32
| | | | | | | | | | | | | | | | | | | | | | the old abi was intended to duplicate glibc's abi at the expense of being ugly and slow, but it turns out glib was not even using that abi except on non-gcc-compatible compilers (which it doesn't even support) and was instead using an exceptions-in-c/unwind-based approach whose abi we could not duplicate anyway without nasty dwarf2/unwind integration. the new abi is copied from a very old glibc abi, which seems to still be supported/present in current glibc. it avoids all unwinding, whether by sjlj or exceptions, and merely maintains a linked list of cleanup functions to be called from the context of pthread_exit. i've made some care to ensure that longjmp out of a cleanup function should work, even though it is not required to. this change breaks abi compatibility with programs which were using pthread cancellation, which is unfortunate, but that's why i'm making the change now rather than later. considering that most pthread features have not been usable until recently anyway, i don't see it as a major issue at this point.
* document iswspace and remove wrongly-included zwsp characterRich Felker2012-02-091-1/+5
|
* fix typo in iswspace space list tableRich Felker2012-02-091-1/+1
|
* fix typo in inotify.hRich Felker2012-02-071-1/+1
|
* protect against cancellation in dlopenRich Felker2012-02-071-2/+5
| | | | | | | i'm not sure that it's "correct" for dlopen to block cancellation when calling constructors for libraries it loads, but it sure seems like the right thing. in any case, dlopen itself needs cancellation blocked.
* reduce some wasted space in dso structureRich Felker2012-02-071-3/+3
|
* declare basename in string.h when _GNU_SOURCE is definedRich Felker2012-02-071-0/+1
| | | | | | note that it still will have the standards-conformant behavior, not the GNU behavior. but at least this prevents broken code from ending up with truncated pointers due to implicit declarations...
* revert hacks for types of stdint.h integer constant macrosRich Felker2012-02-071-4/+4
| | | | | | | | | | | | | per 7.18.4: Each invocation of one of these macros shall expand to an integer constant expression suitable for use in #if preprocessing directives. The type of the expression shall have the same type as would an expression of the corresponding type converted according to the integer promotions. The value of the expression shall be that of the argument. the key phrase is "converted according to the integer promotions". thus there is no intent or allowance that the expression have smaller-than-int types.
* more locale_t interfaces (string stuff) and header updatesRich Felker2012-02-0610-0/+63
| | | | | | this should be everything except for some functions where the non-_l version isn't even implemented yet (mainly some non-ISO-C wcs* functions).
* fix some omissions and mistakes in locale_t interface definitionsRich Felker2012-02-0614-13/+37
|
* add more of the locale_t interfaces, all dummied out to ignore the localeRich Felker2012-02-0619-0/+113
|
* x86_64 vfork implementationRich Felker2012-02-061-0/+12
| | | | untested; should work.
* run ctors/dtors for shared objects loaded with dlopenRich Felker2012-02-061-0/+1
|
* add support for init/finit (constructors and destructors)Rich Felker2012-02-0610-7/+75
| | | | | | | | | | this is mainly in hopes of supporting c++ (not yet possible for other reasons) but will also help applications/libraries which use (and more often, abuse) the gcc __attribute__((__constructor__)) feature in "C" code. x86_64 and arm versions of the new startup asm are untested and may have minor problems.
* add deprecated (removed from posix) [efg]cvt() functionsRich Felker2012-02-064-0/+55
| | | | | these have not been heavily tested, but they should work as described in the old standards. probably broken for non-finite values...
* include dummied-out dlopen and dlsym functions for static binariesRich Felker2012-02-031-1/+10
| | | | | | | | | these don't work (or do anything at all) but at least make it possible to static link programs that insist on "having" dynamic loading support...as long as they don't actually need to use it. adding real support for dlopen/dlsym with static linking is going to be significantly more difficult...
* improve gcc wrapper to support -nostdlib, -nostartfilesRich Felker2012-02-021-1/+1
|
* make stdio open, read, and write operations cancellation pointsRich Felker2012-02-023-5/+28
| | | | | | | | | | it should be noted that only the actual underlying buffer flush and fill operations are cancellable, not reads from or writes to the buffer. this behavior is compatible with POSIX, which makes all cancellation points in stdio optional, and it achieves the goal of allowing cancellation of a thread that's "stuck" on IO (due to a non-responsive socket/pipe peer, slow/stuck hardware, etc.) without imposing any measurable performance cost.
* make passwd/group functions safe against cancellation in stdioRich Felker2012-02-014-6/+35
| | | | these changes are a prerequisite to making stdio cancellable.
* apparently gnu caddr_t is supposed to be char *, not unsigned longRich Felker2012-02-011-1/+1
| | | | this type should never be used anyway, but some old junk uses it..
* fix utmp.h mess, try 2Rich Felker2012-02-011-1/+1
|
* fix previous utmp.h junk commitRich Felker2012-01-311-1/+1
|
* add some missing junk in utmp.hRich Felker2012-01-311-0/+4
