| * | fix major breakage in pthread_once (it was always deadlocking) | Rich Felker | 2011-03-08 | 1 | -8/+7 |
| | | | | | | | the issue was a break statement that was breaking only from the switch, not the enclosing for loop, and a failure to set the final success state. | ||||
| * | fix and optimize non-default-type mutex behavior | Rich Felker | 2011-03-08 | 4 | -25/+19 |
| | | | | | | | | | | problem 1: mutex type from the attribute was being ignored by pthread_mutex_init, so recursive/errorchecking mutexes were never being used at all. problem 2: ownership of recursive mutexes was not being enforced at unlock time. | ||||
| * | implement pthread_mutexattr_[gs]etpshared functions | Rich Felker | 2011-03-08 | 2 | -0/+16 |

| * | fix off-by-one error in sem_(timed)wait (using old sem value instead of new) | Rich Felker | 2011-03-07 | 1 | -1/+1 |
| | | |||||
| * | use the selected clock from the condattr for pthread_cond_timedwait | Rich Felker | 2011-03-07 | 3 | -1/+3 |
| | | |||||
| * | add prototypes for pthread_condattr_* and pthread_rwlockattr_* | Rich Felker | 2011-03-07 | 1 | -0/+12 |
| | | |||||
| * | implement pthread_rwlockattr_* (essentially no-ops) | Rich Felker | 2011-03-07 | 4 | -0/+28 |
| | | |||||
| * | implement pthread_condattr_* interfaces | Rich Felker | 2011-03-07 | 6 | -0/+45 |
| | | | | | | note that, while the attributes are stored, they are not used in pthread_cond_init yet. | ||||
| * | reject invalid attribute settings | Rich Felker | 2011-03-07 | 2 | -0/+2 |
| | | | | | | note that this is a pedantic conformance issue and waste of code. it only affects broken code or code that is probing for conformance. | ||||
| * | implement barrier attribute functions (essentially no-ops) | Rich Felker | 2011-03-07 | 4 | -0/+27 |
| | | |||||
| * | enforce stack size min in pthread_attr_setstacksize | Rich Felker | 2011-03-04 | 1 | -1/+1 |

| | | |||||
| * | implement POSIX shared memory | Rich Felker | 2011-03-03 | 2 | -0/+42 |
| | | |||||
| * | use -L/...../ -lgcc instead of /...../libgcc.a in musl-gcc wrapper | Rich Felker | 2011-03-01 | 1 | -1/+2 |
| | | | | | | | this should avoid warnings about unused libs when not linking, and might fix some other obscure issues too. i might replace this approach with a completely different one soon though. | ||||
| * | depends on settimeofday which needs _GNU_SOURCE feature test | Rich Felker | 2011-03-01 | 1 | -0/+1 |
| | | |||||
| * | implement futimens and utimensat | Rich Felker | 2011-02-27 | 3 | -0/+16 |

| | | |||||
| * | cleanup utf-8 multibyte code, use visibility if possible | Rich Felker | 2011-02-27 | 3 | -84/+5 |
| | | | | | | | | | | | | | | this code was written independently of musl, with support for a the backwards, nonstandard "31-bit unicode" some libraries/apps might want. unfortunately the extra code (inside #ifdef) makes the source harder to read and makes code that should be simple look complex, so i'm removing it. anyone who wants to use the old code can find it in the history or from elsewhere. also, change the visibility of the __fsmu8 state machine table to hidden, if supported. this should improve performance slightly in shared-library builds. | ||||
| * | fix missing prototype for strsignal | Rich Felker | 2011-02-26 | 2 | -0/+2 |
| | | |||||
| * | various changes in preparation for dynamic linking support | Rich Felker | 2011-02-24 | 4 | -8/+24 |
| | | | | | | | | | | | | | | | | | | prefer using visibility=hidden for __libc internal data, rather than an accessor function, if the compiler has visibility. optimize with -O3 for PIC targets (shared library). without heavy inlining, reloading the GOT register in small functions kills performance. 20-30% size increase for a single libc.so is not a big deal, compared to comparaible size increase in every static binaries. use -Bsymbolic-functions, not -Bsymbolic. global variables are subject to COPY relocations, and thus binding their addresses in the library at link time will cause library functions to read the wrong (original) copies instead of the copies made in the main program's bss section. add entry point, _start, for dynamic linker. | ||||
| * | apply feature test protection to memccpy | Rich Felker | 2011-02-24 | 1 | -1/+4 |
| | | |||||
| * | add implementation of memccpy function | Rich Felker | 2011-02-24 | 1 | -0/+32 |
| | | |||||
| * | fix backwards conditional in stpncpy | Rich Felker | 2011-02-24 | 1 | -1/+1 |
| | | | | | | | this only made the function unnecessarily slow on systems with unaligned access, but would of course crash on systems that can't do unaligned accesses (none of which have ports yet). | ||||
| * | rewind must clear the error indicator in addition to seeking | Rich Felker | 2011-02-22 | 1 | -2/+5 |
| | | |||||
| * | change errno to static linkage (improves PIC code generation) | Rich Felker | 2011-02-21 | 1 | -4/+2 |
| | | |||||
| * | cleanup comment cruft in startup code | Rich Felker | 2011-02-21 | 1 | -1/+0 |
| | | |||||
| * | make startup code PIE-compatible | Rich Felker | 2011-02-21 | 1 | -2/+4 |
| | | |||||
| * | remove sample utf-8 code that's not part of the standard library | Rich Felker | 2011-02-21 | 1 | -47/+0 |
| | | |||||
| * | use an accessor function for __libc data pointer when compiled as PIC | Rich Felker | 2011-02-20 | 2 | -4/+19 |
| | | | | | | | | | | | | | | | prior to this change, a large portion of libc was unusable prior to relocation by the dynamic linker, due to dependence on the global data in the __libc structure and the need to obtain its address through the GOT. with this patch, the accessor function __libc_loc is now able to obtain the address of __libc via PC-relative addressing without using the GOT. this means the majority of libc functionality is now accessible right away. naturally, the above statements all depend on having an architecture where PC-relative addressing and jumps/calls are feasible, and a compiler that generates the appropriate code. | ||||
| * | avoid referencing address of extern function from vdprintf | Rich Felker | 2011-02-20 | 1 | -1/+6 |
| | | | | | | | | | this change is in preparation for upcoming PIC/shared library support. the intent is to avoid going through the GOT, mainly so that dprintf is operable immediately, prior to processing of relocations. having dprintf accessible from the dynamic linker will make writing and debugging the dynamic linker much easier. | ||||
| * | shave off 2 bytes from crt1.o _start | Rich Felker | 2011-02-20 | 1 | -2/+2 |
| | | |||||
| * | cleanup asprintf stuff | Rich Felker | 2011-02-20 | 2 | -2/+2 |
| | | |||||
| * | prototypes for GNU asprintf/vasprintf | Rich Felker | 2011-02-20 | 1 | -0/+2 |
| | | |||||
| * | fix %n specifier, again. this time it was storing the wrong value. | Rich Felker | 2011-02-20 | 1 | -7/+7 |
| | | |||||
| * | include sys/sysmacros.h from sys/types.h when _GNU_SOURCE is defined | Rich Felker | 2011-02-20 | 1 | -0/+1 |
| | | |||||
| * | fix typo in inotify structure | Rich Felker | 2011-02-20 | 1 | -1/+1 |
| | | |||||
| * | make malloc(0) return unique pointers rather than NULL | Rich Felker | 2011-02-20 | 2 | -6/+10 |
| | | | | | | | | this change is made with some reluctance, but i think it's for the best. correct programs must handle either behavior, so there is little advantage to having malloc(0) return NULL. and i managed to actually make the malloc code slightly smaller with this change. | ||||
| * | fix simple_malloc malloc(0) behavior not to return non-unique pointers | Rich Felker | 2011-02-20 | 1 | -0/+1 |
| | | |||||
| * | fix simple_malloc size restrictions | Rich Felker | 2011-02-20 | 1 | -5/+6 |
| | | | | | | | do not allow allocations that overflow ptrdiff_t; fix some overflow checks that were not quite right but didn't matter due to address layout implementation. | ||||
| * | fix null pointer dereference introduced in last sigprocmask commit | Rich Felker | 2011-02-20 | 1 | -1/+1 |
| | | |||||
| * | make real symbols for the legacy (nonstandardized) utmp functions | Rich Felker | 2011-02-20 | 2 | -6/+23 |
| | | | | | | | | this is needed in the long term for ABI compatibility anyway, and in the immediate, it helps with building broken programs like GNU screen that try to prototype the functions themselves rather than using the header. | ||||
| * | resolve some header namespace non-issues | Rich Felker | 2011-02-20 | 2 | -3/+0 |
| | | | | | | after re-reading 2.2.2 of POSIX 2008, all of these are in the correct reserved namespaces and do not need protection. | ||||
| * | move the GNU siginfo renaming so it doesn't lead to mismatching names | Rich Felker | 2011-02-20 | 1 | -1/+4 |
| | | |||||
| * | fill in some missing siginfo stuff in signal.h | Rich Felker | 2011-02-20 | 2 | -10/+112 |
