Rich Felker	e74664016b	fix some minor issues in cancellation handling patch signals were wrongly left masked, and cancellability state was not switched to disabled, during the execution of cleanup handlers.	15 years ago
Rich Felker	feee98903c	overhaul pthread cancellation this patch improves the correctness, simplicity, and size of cancellation-related code. modulo any small errors, it should now be completely conformant, safe, and resource-leak free. the notion of entering and exiting cancellation-point context has been completely eliminated and replaced with alternative syscall assembly code for cancellable syscalls. the assembly is responsible for setting up execution context information (stack pointer and address of the syscall instruction) which the cancellation signal handler can use to determine whether the interrupted code was in a cancellable state. these changes eliminate race conditions in the previous generation of cancellation handling code (whereby a cancellation request received just prior to the syscall would not be processed, leaving the syscall to block, potentially indefinitely), and remedy an issue where non-cancellable syscalls made from signal handlers became cancellable if the signal handler interrupted a cancellation point. x86_64 asm is untested and may need a second try to get it right.	15 years ago
Rich Felker	90f09a0dde	remove stupid debug code in wordexp	15 years ago
Rich Felker	d251c2645c	implement wordexp. first try, may be buggy. intended to be safe.	15 years ago
Rich Felker	69cf09c821	avoid setting errno when checking for tty setting errno here is completely valid, but some programs, notably busybox printf, assume that errno will not be set during output and treat this as an error condition. in any case, skipping it slightly reduces code size and saves time.	15 years ago
Rich Felker	088ae5995a	document some changes in the upcoming release	15 years ago
Rich Felker	a3aa89d826	fix O_SYNC definition, cleanup fcntl.h	15 years ago
Rich Felker	0a84e72c42	fix FAPPEND typo on x86_64 (previously only fixed on i386)	15 years ago
Rich Felker	c2b18f3531	fcntl.h: move macros that do not vary between archs out of bits	15 years ago
Rich Felker	ace973637f	fix broken fcntl locks on x86_64	15 years ago
Rich Felker	b172dc8b58	make tmpfile slightly more efficient (use unlink syscall instead of remove)	15 years ago
Rich Felker	9b96220e5a	fix typo in legacy FAPPEND definition	15 years ago
Rich Felker	33a3f202d1	add useless type fd_mask. it's in the reserved namespace.	15 years ago
Rich Felker	e983aea0ae	change sem_trywait algorithm so it never has to call __wake	15 years ago
Rich Felker	ec2e50d0d7	cheap trick to further optimize locking normal mutexes	15 years ago
Rich Felker	016a5dc192	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.	15 years ago
Rich Felker	9beb6330c0	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.	15 years ago
Rich Felker	19c1830eaa	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...	15 years ago
Rich Felker	a77411a50d	remove useless SIGPIPE protection from syslog per the standard, SIGPIPE is not generated for SOCK_DGRAM.	15 years ago
Rich Felker	a444ee3410	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.	15 years ago
Rich Felker	07e865cc5a	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.	15 years ago
Rich Felker	b5b43b6d62	add syslog.h cruft for syslogd to use...	15 years ago
Rich Felker	b778a2ba69	add profile for getmntent_r	15 years ago
Rich Felker	55b123b5ed	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...	15 years ago
Rich Felker	6f0259a4fc	fix bug whereby getopt_long allowed mismatch in last char of option name	15 years ago
Rich Felker	45a3219944	fix typos on RLIM_NLIMITS, remove _GNU_SOURCE test for it RLIM_* is in the reserved namespace for this header	15 years ago
Rich Felker	cac7d837cc	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.	15 years ago
Rich Felker	91e836fda7	implement getgrouplist (for initgroups), formerly dummied-out	15 years ago
Rich Felker	3f44f298e4	fix prototypes/signature for setgroups, etc.	15 years ago
Rich Felker	0f5b43550c	fix incorrect GNU sighandler_t typedef	15 years ago
Rich Felker	6597f9ac13	implement memrchr (nonstandard) and optimize strrchr in terms of it	15 years ago
Rich Felker	750b738e53	add ptsname_r (nonstandard) and split ptsname (standard) to separate file this eliminates the ugly static buffer in programs that use ptsname_r.	15 years ago
Rich Felker	e2915eeeea	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.	15 years ago
Rich Felker	0913560a3f	more changes for upcoming 0.7.8	15 years ago
Rich Felker	c89862660b	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.	15 years ago
Rich Felker	c546be175c	move bswap functions to static inline in byteswap.h	15 years ago
Rich Felker	4f4ba4c02f	fix broken bswap_32	15 years ago
Rich Felker	0729fd9fd9	utmpx.h is no longer under standards, so expose ut_exit structure	15 years ago
Rich Felker	7ecab79f58	add some traditional aliases to stat.h	15 years ago
Rich Felker	e514228043	fix printf("%.9g", 1.1) and similar not dropping trailing zeros	15 years ago
Rich Felker	209f2bbd95	add missing rlimit macros	15 years ago
Rich Felker	43b2e9bf26	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.	15 years ago
Rich Felker	28bde3b787	cleanup types stuff in headers, fix missing u_int*_t in sys/types.h	15 years ago
Rich Felker	dae17a1aaf	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...	15 years ago
Rich Felker	52458cfa8c	fix fputwc return value	15 years ago
Rich Felker	0161244784	remove ugly warning-suppression hack from crypt - this invokes UB!	15 years ago
Rich Felker	5eaa22132b	update README since we now DO have a mailing list	15 years ago
Rich Felker	2555fe1b6d	add some ugly legacy type names in sys/types.h (u_char etc.)	15 years ago
Rich Felker	691b20bec0	add legacy BSD-style timer*() macros in sys/time.h	15 years ago
Rich Felker	4a19634f07	add missing UTIME_* macros in sys/stat.h	15 years ago
