2012-02-17remove -std=gnu99 from musl-gcc wrapperRich Felker-1/+1
while probably desirable, changing the default language variant is outside the scope of the wrapper's responsibility.
2012-02-17two fixes for "make install" handling of shared libsRich Felker-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.
2012-02-17add get_current_dir_name functionRich Felker-0/+13
2012-02-15add float_t and double_t to math.hRich Felker-0/+11
2012-02-11fix default nameserver when resolv.conf doesn't existRich Felker-1/+2
2012-02-11fix illegal goto out of cleanup context in dns lookupsRich Felker-3/+3
2012-02-09small fix for new pthread cleanup stuffRich Felker-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.
2012-02-09replace bad cancellation cleanup abi with a sane oneRich Felker-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.
2012-02-09document iswspace and remove wrongly-included zwsp characterRich Felker-1/+5
2012-02-09fix typo in iswspace space list tableRich Felker-1/+1
2012-02-07fix typo in inotify.hRich Felker-1/+1
2012-02-07protect against cancellation in dlopenRich Felker-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.
2012-02-07reduce some wasted space in dso structureRich Felker-3/+3
2012-02-07declare basename in string.h when _GNU_SOURCE is definedRich Felker-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...
2012-02-07revert hacks for types of stdint.h integer constant macrosRich Felker-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.
2012-02-06more locale_t interfaces (string stuff) and header updatesRich Felker-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).
2012-02-06fix some omissions and mistakes in locale_t interface definitionsRich Felker-13/+37
2012-02-06add more of the locale_t interfaces, all dummied out to ignore the localeRich Felker-0/+113
2012-02-06x86_64 vfork implementationRich Felker-0/+12
untested; should work.
2012-02-06run ctors/dtors for shared objects loaded with dlopenRich Felker-0/+1
2012-02-06add support for init/finit (constructors and destructors)Rich Felker-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.
2012-02-06add deprecated (removed from posix) [efg]cvt() functionsRich Felker-0/+55
these have not been heavily tested, but they should work as described in the old standards. probably broken for non-finite values...
2012-02-03include dummied-out dlopen and dlsym functions for static binariesRich Felker-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...
2012-02-02improve gcc wrapper to support -nostdlib, -nostartfilesRich Felker-1/+1
2012-02-02make stdio open, read, and write operations cancellation pointsRich Felker-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.
2012-02-01make passwd/group functions safe against cancellation in stdioRich Felker-6/+35
these changes are a prerequisite to making stdio cancellable.
2012-02-01apparently gnu caddr_t is supposed to be char *, not unsigned longRich Felker-1/+1
this type should never be used anyway, but some old junk uses it..
2012-02-01fix utmp.h mess, try 2Rich Felker-1/+1
2012-01-31fix previous utmp.h junk commitRich Felker-1/+1
2012-01-31add some missing junk in utmp.hRich Felker-0/+4
2012-01-29add fgetpwent (nonstandard function)Rich Felker-0/+14
based on patch by Jeremy Huntwork
2012-01-28add linux setfs[ug]id syscall wrappersRich Felker-0/+36
patch by Jeremy Huntwork
2012-01-26remove useless "extern" keywords in headersRich Felker-3/+3
2012-01-25fix typo in FPE_FLTUND definition, signal.hRich Felker-1/+1
2012-01-24add MIN/MAX macros to sys/param.hRich Felker-0/+5
this is a nonstandard junk header anyway, so just do what apps expect..
2012-01-24add legacy futimes and lutimes functionsRich Felker-0/+28
based on patch by sh4rm4. these functions are deprecated; futimens and utimensat should be used instead in new programs.
2012-01-24make gcc wrapper support -shared correctlyRich Felker-2/+7
it was previously attempting to link start files as part of shared objects. this is definitely wrong and depending on the platform and linker could range from just adding extraneous junk to introducing textrels to making linking fail entirely.
2012-01-23make glob mark symlinks-to-directories with the GLOB_MARK flagRich Felker-1/+1
POSIX is unclear on whether it should, but all historical implementations seem to behave this way, and it seems more useful to applications.
2012-01-23fix broken copy relocations from dynamic linker cleanupRich Felker-1/+4
this issue affected programs which use global variables exported by non-libc libraries.
2012-01-23dynamic linker support for PIE binaries (position-independent main program)Rich Felker-3/+6
even with this change, PIE will not work yet due to deficiencies in the crt1.o startup code.
2012-01-23cleanup dynamic linker, removing some code duplicationRich Felker-80/+66
2012-01-23update release notes for 0.8.4v0.8.4Rich Felker-3/+5
2012-01-22fix cancellation failure in single-threaded programsRich Felker-1/+1
even a single-threaded program can be cancellable, e.g. if it's called pthread_cancel(pthread_self()). the correct predicate to check is not whether multiple threads have been invoked, but whether pthread_self has been invoked.
2012-01-22support GLOB_PERIOD flag (GNU extension) to glob functionRich Felker-1/+2
patch by sh4rm4
2012-01-22update WHATSNEW in preparation for 0.8.4 (not finished)Rich Felker-0/+30
2012-01-20use prlimit syscall for getrlimit/setrlimitRich Felker-4/+14
this allows the full range of 64-bit limit arguments even on 32-bit systems. fallback to the old syscalls on old kernels that don't support prlimit.
2012-01-20add prlimit syscall wrapperRich Felker-0/+18
2012-01-20fix dynamic linker not to depend on DYNAMIC ptr in 0th entry of GOTRich Felker-3/+12
this fixes an issue using gold instead of gnu ld for linking. it also should eliminate the need of the startup code to even load/pass the got address to the dynamic linker. based on patch submitted by sh4rm4 with minor cosmetic changes. further cleanup will follow.
2012-01-18alias basename to glibc name for it, to meet abi goalsRich Felker-0/+3
note that regardless of the name used, basename is always conformant. it never takes on the bogus gnu behavior, unlike glibc where basename is nonconformant when declared manually without including libgen.h.
2012-01-17fix char signedness bug in dynlinker hash functionRich Felker-1/+2
this only affects non-ascii symbol names, which are probably not in use anyway..
