2012-02-07fix typo in inotify.hRich Felker1-1/+1
2012-02-07protect against cancellation in dlopenRich Felker1-2/+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 Felker1-3/+3
2012-02-07declare basename in string.h when _GNU_SOURCE is definedRich Felker1-0/+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 Felker1-4/+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 Felker10-0/+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 Felker14-13/+37
2012-02-06add more of the locale_t interfaces, all dummied out to ignore the localeRich Felker19-0/+113
2012-02-06x86_64 vfork implementationRich Felker1-0/+12
untested; should work.
2012-02-06run ctors/dtors for shared objects loaded with dlopenRich Felker1-0/+1
2012-02-06add support for init/finit (constructors and destructors)Rich Felker10-7/+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 Felker4-0/+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 Felker1-1/+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 Felker1-1/+1
2012-02-02make stdio open, read, and write operations cancellation pointsRich Felker3-5/+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 Felker4-6/+35
these changes are a prerequisite to making stdio cancellable.
2012-02-01apparently gnu caddr_t is supposed to be char *, not unsigned longRich Felker1-1/+1
this type should never be used anyway, but some old junk uses it..
2012-02-01fix utmp.h mess, try 2Rich Felker1-1/+1
2012-01-31fix previous utmp.h junk commitRich Felker1-1/+1
2012-01-31add some missing junk in utmp.hRich Felker1-0/+4
2012-01-29add fgetpwent (nonstandard function)Rich Felker2-0/+14
based on patch by Jeremy Huntwork
2012-01-28add linux setfs[ug]id syscall wrappersRich Felker3-0/+36
patch by Jeremy Huntwork
2012-01-26remove useless "extern" keywords in headersRich Felker3-3/+3
2012-01-25fix typo in FPE_FLTUND definition, signal.hRich Felker1-1/+1
2012-01-24add MIN/MAX macros to sys/param.hRich Felker1-0/+5
this is a nonstandard junk header anyway, so just do what apps expect..
2012-01-24add legacy futimes and lutimes functionsRich Felker3-0/+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 Felker1-2/+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 Felker1-1/+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 Felker1-1/+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 Felker1-3/+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 Felker1-80/+66
2012-01-23update release notes for 0.8.4v0.8.4Rich Felker1-3/+5
2012-01-22fix cancellation failure in single-threaded programsRich Felker1-1/+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 Felker1-1/+2
patch by sh4rm4
2012-01-22update WHATSNEW in preparation for 0.8.4 (not finished)Rich Felker1-0/+30
2012-01-20use prlimit syscall for getrlimit/setrlimitRich Felker2-4/+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 Felker3-0/+18
2012-01-20fix dynamic linker not to depend on DYNAMIC ptr in 0th entry of GOTRich Felker1-3/+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 Felker1-0/+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 Felker1-1/+2
this only affects non-ascii symbol names, which are probably not in use anyway..
2011-12-23fix broken reboot wrapper (syscall needs extra silly magic arguments...)Rich Felker1-1/+1
2011-11-16fix issue with excessive mremap syscalls on reallocRich Felker1-4/+2
CHUNK_SIZE macro was defined incorrectly and shaving off at least one significant bit in the size of mmapped chunks, resulting in the test for oldlen==newlen always failing and incurring a syscall. fortunately i don't think this issue caused any other observable behavior; the definition worked correctly for all non-mmapped chunks where its correctness matters more, since their lengths are always multiples of the alignment.
2011-11-10fix __cplusplus extern "C" closing brace in pty.h (typo?)Rich Felker1-1/+1
2011-11-10fix signed overflows at most-negative values in ato(i|l|ll)Rich Felker3-6/+9
patch by Pascal Cuoq (with minor tweaks to comments)
2011-11-10fix all missing instances of __cplusplus checks/extern "C" in headersRich Felker21-1/+166
patch by Arvid Picciani (aep)
2011-10-26report sem value overflows in sem_postRich Felker1-0/+4
this is not required by the standard, but it's nicer than corrupting the state and rather inexpensive.
2011-10-17add some missing GNU FNM_* extensions to the headerRich Felker1-1/+3
note that none of these are implemented, and programs depending on them may break... patch by sh4rm4
2011-10-17fix some details in ugly stuff that doesn't belong in libcRich Felker2-6/+8
patches by sh4rm4, presumably needed to make gdb or some similar junk happy...
2011-10-15don't define wchar_t on c++Rich Felker3-0/+6
it's a keyword in c++ (wtf). i'm not sure this is the cleanest solution; it might be better to avoid ever defining __NEED_wchar_t on c++. but in any case, this works for now.
2011-10-14support vfork on i386Rich Felker1-0/+14
