| * | fix broken fcntl locks on x86_64 | Rich Felker | 2011-04-14 | 1 | -3/+3 |
| * | make tmpfile slightly more efficient (use unlink syscall instead of remove) | Rich Felker | 2011-04-14 | 1 | -1/+1 |
| * | fix typo in legacy FAPPEND definition | Rich Felker | 2011-04-14 | 1 | -1/+1 |
| * | add useless type fd_mask. it's in the reserved namespace. | Rich Felker | 2011-04-14 | 1 | -0/+2 |
| * | change sem_trywait algorithm so it never has to call __wake | Rich Felker | 2011-04-14 | 1 | -3/+2 |
| * | cheap trick to further optimize locking normal mutexes | Rich Felker | 2011-04-14 | 2 | -2/+2 |
| * | use a separate signal from SIGCANCEL for SIGEV_THREAD timers•••otherwise we cannot support an application's desire to use
asynchronous cancellation within the callback function. this change
also slightly debloats pthread_create.c.
| Rich Felker | 2011-04-14 | 6 | -11/+29 |
| * | simplify cancellation point handling•••we take advantage of the fact that unless self->cancelpt is 1,
cancellation cannot happen. so just increment it by 2 to temporarily
block cancellation. this drops pthread_create.o well under 1k.
| Rich Felker | 2011-04-13 | 2 | -16/+5 |
| * | simplify syslog, add vsyslog interface (nonstandard)•••with datagram sockets, depending on fprintf not to flush the output
early was very fragile; the new version simply uses a small fixed-size
buffer. it could be updated to dynamic-allocate large buffers if
needed, but i can't envision any admin being happy about finding
64kb-long lines in their syslog...
| Rich Felker | 2011-04-13 | 1 | -31/+36 |
| * | remove useless SIGPIPE protection from syslog•••per the standard, SIGPIPE is not generated for SOCK_DGRAM.
| Rich Felker | 2011-04-13 | 1 | -9/+0 |
| * | fix syslog (corrected SIGPIPE blocking, and using dgram instead of stream)•••it actually appears the hacks to block SIGPIPE are probably not
necessary, and potentially harmful. if i can confirm this, i'll remove
them.
| Rich Felker | 2011-04-13 | 1 | -10/+8 |
| * | numerous fixes to sysv ipc•••some of these definitions were just plain wrong, others based on
outdated ancient "non-64" versions of the kernel interface.
as much as possible has now been moved out of bits/*
these changes break abi (the old abi for these functions was wrong),
but since they were not working anyway it can hardly matter.
| Rich Felker | 2011-04-13 | 12 | -66/+96 |
| * | add syslog.h cruft for syslogd to use... | Rich Felker | 2011-04-13 | 1 | -0/+45 |
| * | add profile for getmntent_r | Rich Felker | 2011-04-13 | 1 | -0/+1 |
| * | add syscall wrapper for flock•••it should be noted that flock does not mix well with standard fcntl
locking, but nonetheless some applications will attempt to use flock
instead of fcntl if both exist. options to configure or small patches
may be needed. debian maintainers have plenty of experience with this
unfortunate situation...
| Rich Felker | 2011-04-13 | 1 | -0/+7 |
| * | fix bug whereby getopt_long allowed mismatch in last char of option name | Rich Felker | 2011-04-13 | 1 | -1/+1 |
| * | fix typos on RLIM_NLIMITS, remove _GNU_SOURCE test for it•••RLIM_* is in the reserved namespace for this header
| Rich Felker | 2011-04-13 | 1 | -3/+1 |
| * | fix and cleanup suseconds_t/timeval stuff (broken on 64-bit)•••trash in the upper 32 bits was making the kernel sleep forever in
select on 64-bit systems.
| Rich Felker | 2011-04-13 | 3 | -10/+2 |
| * | implement getgrouplist (for initgroups), formerly dummied-out | Rich Felker | 2011-04-13 | 1 | -4/+16 |
| * | fix prototypes/signature for setgroups, etc. | Rich Felker | 2011-04-13 | 3 | -2/+8 |
| * | fix incorrect GNU sighandler_t typedef | Rich Felker | 2011-04-13 | 1 | -1/+1 |
| * | implement memrchr (nonstandard) and optimize strrchr in terms of it | Rich Felker | 2011-04-13 | 3 | -4/+16 |
| * | add ptsname_r (nonstandard) and split ptsname (standard) to separate file•••this eliminates the ugly static buffer in programs that use ptsname_r.
| Rich Felker | 2011-04-13 | 3 | -11/+17 |
| * | speed up threaded fork•••after fork, we have a new process and the pid is equal to the tid of
the new main thread. there is no need to make two separate syscalls to
obtain the same number.
| Rich Felker | 2011-04-12 | 1 | -2/+1 |
| * | more changes for upcoming 0.7.8 | Rich Felker | 2011-04-12 | 1 | -1/+12 |
| * | optimize ntohl etc. in terms of bswap functions•••we can do this without violating the namespace now that they are
macros/inline functions rather than extern functions. the motivation
is that gcc was generating giant, slow, horrible code for the old
functions, and now generates a single byte-swapping instruction.
| Rich Felker | 2011-04-12 | 4 | -20/+12 |
| * | move bswap functions to static inline in byteswap.h | Rich Felker | 2011-04-12 | 3 | -16/+25 |
| * | fix broken bswap_32 | Rich Felker | 2011-04-12 | 1 | -1/+1 |
| * | utmpx.h is no longer under standards, so expose ut_exit structure | Rich Felker | 2011-04-12 | 1 | -3/+3 |
| * | add some traditional aliases to stat.h | Rich Felker | 2011-04-12 | 1 | -0/+6 |
| * | fix printf("%.9g", 1.1) and similar not dropping trailing zeros | Rich Felker | 2011-04-12 | 1 | -1/+3 |
| * | add missing rlimit macros | Rich Felker | 2011-04-12 | 1 | -0/+8 |
| * | more types cleanup•••the basic idea is that the only things in alltypes.h should be types
that either vary from system to system (in practice, not just in
theoretical la-la land - this is the implementation so we choose what
constraints we want to impose on ports) or which are needed by
multiple system headers.
| Rich Felker | 2011-04-11 | 3 | -18/+3 |
| * | cleanup types stuff in headers, fix missing u_int*_t in sys/types.h | Rich Felker | 2011-04-11 | 4 | -29/+19 |
| * | fix errno handling in scandir:•••1. saved errno was not being restored, illegally clearing errno to 0.
2. no need to backup and save errno around free; it will not touch
except perhaps when the program has already invoked UB...
| Rich Felker | 2011-04-11 | 1 | -2/+1 |
| * | fix fputwc return value | Rich Felker | 2011-04-11 | 1 | -1/+1 |
| * | remove ugly warning-suppression hack from crypt - this invokes UB! | Rich Felker | 2011-04-11 | 1 | -1/+1 |
| * | update README since we now DO have a mailing list | Rich Felker | 2011-04-11 | 1 | -4/+4 |
| * | add some ugly legacy type names in sys/types.h (u_char etc.) | Rich Felker | 2011-04-10 | 1 | -0/+8 |
| * | add legacy BSD-style timer*() macros in sys/time.h | Rich Felker | 2011-04-10 | 1 | -0/+10 |
| * | add missing UTIME_* macros in sys/stat.h | Rich Felker | 2011-04-10 | 1 | -0/+3 |
| * | add missing float.h macros•••actually FLT_ROUNDS needs to expand to a static inline function that
obtains the current rounding mode and returns it, but that will be
added later with fenv.h stuff.
| Rich Felker | 2011-04-10 | 2 | -0/+6 |
| * | run pthread tsd destructors when a timer thread pretends to exit | Rich Felker | 2011-04-09 | 1 | -0/+6 |
| * | greatly improve SIGEV_THREAD timers•••calling pthread_exit from, or pthread_cancel on, the timer callback
thread will no longer destroy the timer.
| Rich Felker | 2011-04-09 | 3 | -15/+21 |
| * | prepare notes for 0.7.8 release | Rich Felker | 2011-04-09 | 1 | -0/+18 |
| * | work around a nasty bug in linux readv syscall•••according to posix, readv "shall be equivalent to read(), except..."
that it places the data into the buffers specified by the iov array.
however on linux, when reading from a terminal, each iov element
behaves almost like a separate read. this means that if the first iov
exactly satisfied the request (e.g. a length-one read of '\n') and the
second iov is nonzero length, the syscall will block again after
getting the blank line from the terminal until another line is read.
simply put, entering a single blank line becomes impossible.
the solution, fortunately, is simple. whenever the buffer size is
nonzero, reduce the length of the requested read by one byte and let
the last byte go through the buffer. this way, readv will already be
in the second (and last) iov, and won't re-block on the second iov.

| * | better fix sysconf pthread stack min | Rich Felker | 2011-04-08 | 1 | -1/+1 |
| * | consistency with pthread stack min in limits.h | Rich Felker | 2011-04-08 | 1 | -1/+1 |
| * | fix broken sigsetjmp on x86_64 | Rich Felker | 2011-04-08 | 1 | -7/+9 |
| * | workaround broken msghdr struct on 64bit linux•••POSIX clearly specifies the type of msg_iovlen and msg_controllen, and
Linux ignores it and makes them both size_t instead. to work around
this we add padding (instead of just using the wrong types like glibc
does), but we also need to patch-up the struct before passing it to
the kernel in case the caller did not zero-fill it.
if i could trust the kernel to just ignore the upper 32 bits, this
would not be necessary, but i don't think it will ignore them...
