| * | 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.

| * | 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...

| * | 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.

| * | 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.

| * | 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...

| * | fix ipv6 address printing: 2001 appeared as 201, etc. | Rich Felker | 2011-04-08 | 1 | -3/+5 |
| * | fix broken dns response parsing code that made most ipv6 lookups fail | Rich Felker | 2011-04-08 | 1 | -4/+6 |
| * | return the requested string as the "canonical name" for numeric addresses•••previously NULL was returned in ai_canonname, resulting in crashes in
some callers. this behavior was incorrect. note however that the new
behavior differs from glibc, which performs reverse dns lookups. POSIX
is very clear that a reverse DNS lookup must not be performed for
numeric addresses.

| * | fixed crash in new rsyscall (failure to set sa_flags for signal handler) | Rich Felker | 2011-04-06 | 1 | -0/+2 |
| * | consistency: change all remaining syscalls to use SYS_ rather than __NR_ prefix | Rich Felker | 2011-04-06 | 38 | -40/+40 |
| * | move rsyscall out of pthread_create module•••this is something of a tradeoff, as now set*id() functions, rather
than pthread_create, are what pull in the code overhead for dealing
with linux's refusal to implement proper POSIX thread-vs-process
semantics. my motivations are:
1. it's cleaner this way, especially cleaner to optimize out the
rsyscall locking overhead from pthread_create when it's not needed.
2. it's expected that only a tiny number of core system programs will
ever use set*id() functions, whereas many programs may want to use
threads, and making thread overhead tiny is an incentive for "light"
programs to try threads.

| * | fix prototype for strsep | Rich Felker | 2011-04-06 | 2 | -1/+2 |
| * | fix completely bogus loop condition in getmntent_r•••somehow this worked on my simple fstab, but horribly broke in general,
leading to use of uninitialized offset array and crashes.
| Rich Felker | 2011-04-06 | 1 | -1/+1 |
| * | major semaphore improvements (performance and correctness)•••1. make sem_[timed]wait interruptible by signals, per POSIX
2. keep a waiter count in order to avoid unnecessary futex wake syscalls
| Rich Felker | 2011-04-06 | 5 | -21/+37 |
| * | fix signal-based timers with null sigevent argument•••since timer_create is no longer allocating a structure for the timer_t
and simply using the kernel timer id, it was impossible to specify the
timer_t as the argument to the signal handler. the solution is to pass
the null sigevent pointer on to the kernel, rather than filling it in
userspace, so that the kernel does the right thing. however, that
precludes the clever timerid-versus-threadid encoding we were doing.
instead, just assume timerids are below 1M and thread pointers are
above 1M. (in perspective: timerids are sequentially allocated and
seem limited to 32k, and thread pointers are at roughly 3G.)

| * | fix incorrect (and conflicting on LP64 archs) types for sysv ipc msgq functions | Rich Felker | 2011-04-06 | 2 | -2/+2 |
| * | fix (hopefully) statvfs breakage on x86_64 that resulted from fixing i386... | Rich Felker | 2011-04-05 | 2 | -2/+10 |
| * | document more changes | Rich Felker | 2011-04-05 | 1 | -0/+2 |
| * | new framework to inhibit thread cancellation when needed•••with these small changes, libc functions which need to call functions
which are cancellation points, but which themselves must not be
cancellation points, can use the CANCELPT_INHIBIT and CANCELPT_RESUME
macros to temporarily inhibit all cancellation.
| Rich Felker | 2011-04-05 | 3 | -5/+17 |
| * | add ip6 pktinfo stuff for x86_64•••these defs should probably all be moved out of bits and unified...
