| * | overhaul clone syscall wrapping•••several things are changed. first, i have removed the old __uniclone
function signature and replaced it with the "standard" linux
__clone/clone signature. this was necessary to expose clone to
applications anyway, and it makes it easier to port __clone to new
archs, since it's now testable independently of pthread_create.
secondly, i have removed all references to the ugly ldt descriptor
structure (i386 only) from the c code and pthread structure. in places
where it is needed, it is now created on the stack just when it's
needed, in assembly code. thus, the i386 __clone function takes the
desired thread pointer as its argument, rather than an ldt descriptor
pointer, just like on all other sane archs. this should not affect
applications since there is really no way an application can use clone
with threads/tls in a way that doesn't horribly conflict with and
clobber the underlying implementation's use. applications are expected
to use clone only for creating actual processes, possibly with new
namespace features and whatnot.

| * | implement ptrace syscall wrapper (untested) | Rich Felker | 2011-09-15 | 1 | -1/+1 |
| * | fix return types for aio_read and aio_write again•••previous fix was backwards and propagated the wrong type rather than
the right one...
| Rich Felker | 2011-09-13 | 1 | -2/+2 |
| * | fix various errors in function signatures/prototypes found by nsz | Rich Felker | 2011-09-13 | 4 | -8/+8 |
| * | fix prototypes for aio_read and aio_write | Rich Felker | 2011-09-13 | 1 | -2/+2 |
| * | implement gnu sigisemptyset | Rich Felker | 2011-09-12 | 1 | -0/+1 |
| * | add prototypes for GNU *_unlocked stdio functions•••actually these are just weak aliases for the normal locking versions
right now, and they will probably stay that way since making them
lock-free without slowing down the normal versions would require
significant code duplication for no benefit.
| Rich Felker | 2011-09-11 | 1 | -0/+4 |
| * | add dummied strverscmp (obnoxious GNU function)•••programs that use this tend to horribly botch international text
support, so it's questionable whether we want to support it even in
the long term... for now, it's just a dummy that calls strcmp.
| Rich Felker | 2011-09-11 | 1 | -0/+1 |
| * | declare alloca in stdlib.h when _GNU_SOURCE is defined | Rich Felker | 2011-09-11 | 1 | -0/+1 |
| * | implement POSIX asynchronous io•••some features are not yet supported, and only minimal testing has been
performed. should be considered experimental at this point.
| Rich Felker | 2011-09-09 | 1 | -0/+60 |
| * | implement fmemopen•••testing so far has been minimal. may need further work.
| Rich Felker | 2011-09-03 | 1 | -0/+1 |
| * | implement open_wmemstream•••not heavily tested, but it seems to be correct, including the odd
behavior that seeking is in terms of wide character count. this
precludes any simple buffering, so we just make the stream unbuffered.
| Rich Felker | 2011-09-03 | 1 | -0/+1 |
| * | implement open_memstream•••this is the first attempt, and may have bugs. only minimal testing has
been performed.

| * | fix missing prototypes/wrong signature for psiginfo, psignal | Rich Felker | 2011-09-02 | 1 | -0/+3 |
| * | fix broken FD_* macros on 64-bit targets•••1 is too small if int is 32-bit but unsigned long is 64-bit. be
explicit and use 1UL.
| Rich Felker | 2011-08-27 | 1 | -3/+3 |
| * | macro for pthread_equal•••no sense bloating apps with a function call for an equality comparison...
| Rich Felker | 2011-08-14 | 1 | -0/+2 |
| * | implement forkall•••this is a "nonstandard" function that was "rejected" by POSIX, but
nonetheless had its behavior documented in the POSIX rationale for
fork. it's present on solaris and possibly some other systems, and
duplicates the whole calling process, not just a single thread. glibc
does not have this function. it should not be used in programs
intending to be portable, but may be useful for testing,
checkpointing, etc. and it's an interesting (and quite small) example
of the usefulness of the __synccall framework originally written to
work around deficiencies in linux's setuid syscall.
| Rich Felker | 2011-08-12 | 1 | -0/+1 |
| * | consistency: use struct __ucontext instead of ucontext_t in prototypes•••this is necessary to avoid build errors if feature test macros are not
properly defined when including ucontext.h
| Rich Felker | 2011-07-31 | 1 | -1/+1 |
| * | add missing signalfd flags | Rich Felker | 2011-07-09 | 1 | -0/+3 |
| * | fill in junk in stropts.h•••STREAMS are utterly useless as far as I can tell, but some software
was apparently broken by the presence of stropts.h but lack of macros
it's supposed to define...
| Rich Felker | 2011-06-30 | 1 | -1/+123 |
| * | add and consolidate nasty stdio_ext junk•••hopefully this resolves the rest of the issues with hideously
nonportable hacks in programs that use gnulib.
| Rich Felker | 2011-06-30 | 1 | -0/+27 |
| * | implement the nonstandard GNU function fpurge•••this is a really ugly and backwards function, but its presence will
prevent lots of broken gnulib software from trying to define its own
version of fpurge and thereby failing to build or worse.
| Rich Felker | 2011-06-30 | 1 | -0/+1 |
| * | avoid errors in ucontext.h when no feature test macros are defined | Rich Felker | 2011-06-29 | 1 | -3/+5 |

| * | move all limits that don't vary out of bits/limits.h, into main limits.h | Rich Felker | 2011-06-25 | 1 | -0/+22 |
| * | copy-paste error in prctl.h | Rich Felker | 2011-06-18 | 1 | -1/+1 |
| * | fix some struct padding to match LSB/glibc ABI where it may be helpful | Rich Felker | 2011-06-16 | 2 | -2/+5 |
| * | duplicate re_nsub in LSB/glibc ABI compatible location | Rich Felker | 2011-06-16 | 1 | -1/+2 |
| * | add netpacket/packet.h•••looks like busybox is going to want it, and apparently some other
low-level network software does too...
| Rich Felker | 2011-06-09 | 1 | -0/+44 |
| * | isgreater etc. relation macros for math.h | Rich Felker | 2011-06-08 | 1 | -0/+18 |
| * | define MQ_PRIO_MAX | Rich Felker | 2011-06-07 | 1 | -0/+1 |
| * | add support for POSIX message queues, except mq_notify | Rich Felker | 2011-06-07 | 1 | -0/+34 |
| * | use __attribute__((const)) for errno and pthread_self if __GNUC__ is defined•••this is not too ugly and should result in significant code size and
performance improvements for many programs.
| Rich Felker | 2011-06-06 | 2 | -0/+6 |
| * | fix handling of d_name in struct dirent•••basically there are 3 choices for how to implement this variable-size
string member:
1. C99 flexible array member: breaks using dirent.h with pre-C99 compiler.
2. old way: length-1 string: generates array bounds warnings in caller.
3. new way: length-NAME_MAX string. no problems, simplifies all code.
of course the usable part in the pointer returned by readdir might be
shorter than NAME_MAX+1 bytes, but that is allowed by the standard and
doesn't hurt anything.

| * | missing prototypes for mbsnrtowcs and wcsnrtombs | Rich Felker | 2011-05-30 | 1 | -0/+6 |
| * | implement pthread_[sg]etconcurrency.•••there is a resource limit of 0 bits to store the concurrency level
requested. thus any positive level exceeds a resource limit, resulting
in EAGAIN. :-)
| Rich Felker | 2011-05-30 | 1 | -0/+3 |
| * | initial implementation of posix_spawn•••file actions are not yet implemented, but everything else should be
mostly complete and roughly correct.
| Rich Felker | 2011-05-28 | 1 | -0/+67 |
| * | eventfd syscall wrapper and read/write wrappers | Rich Felker | 2011-05-08 | 1 | -0/+25 |
| * | add SA_NOMASK alias for SA_NODEFER with _GNU_SOURCE | Rich Felker | 2011-05-05 | 1 | -0/+1 |
| * | use compiler builtins for variadic macros when available•••this slightly cuts down on the degree musl "fights with" gcc, but more
importantly, it fixes a critical bug when gcc inlines a variadic
function and optimizes out the variadic arguments due to noticing that
they were "not used" (by __builtin_va_arg).
we leave the old code in place if __GNUC__ >= 3 is false; it seems
like it might be necessary at least for tinycc support and perhaps if
anyone ever gets around to fixing gcc 2.95.3 enough to make it work..
| Rich Felker | 2011-04-27 | 1 | -0/+7 |
| * | correct variadic prototypes for execl* family•••the old versions worked, but conflicted with programs which declared
their own prototypes and generated warnings with some versions of gcc.
| Rich Felker | 2011-04-27 | 1 | -3/+3 |
| * | function signature fix: add const qualifier to mempcpy src arg | Rich Felker | 2011-04-26 | 1 | -1/+1 |
