musl - musl - an implementation of the standard library for Linux-based systems

Age	Commit message (Collapse)	Author	Lines
2012-05-06	add isastream (obsolete STREAMS junk)	Rich Felker	-0/+7
	apparently some packages see stropts.h and want to be able to use this. the implementation checks that the file descriptor is valid by using fcntl/F_GETFD so it can report an error if not (as specified).
2012-05-03	implement stub versions of sched_*	Rich Felker	-10/+0
	these actually work, but for now they prohibit actually setting priority levels and report min/max priority as 0.
2012-04-24	ditch the priority inheritance locks; use malloc's version of lock	Rich Felker	-9/+9
	i did some testing trying to switch malloc to use the new internal lock with priority inheritance, and my malloc contention test got 20-100 times slower. if priority inheritance futexes are this slow, it's simply too high a price to pay for avoiding priority inversion. maybe we can consider them somewhere down the road once the kernel folks get their act together on this (and perferably don't link it to glibc's inefficient lock API)... as such, i've switch __lock to use malloc's implementation of lightweight locks, and updated all the users of the code to use an array with a waiter count for their locks. this should give optimal performance in the vast majority of cases, and it's simple. malloc is still using its own internal copy of the lock code because it seems to yield measurably better performance with -O3 when it's inlined (20% or more difference in the contention stress test).
2012-04-22	implement getusershell, etc. legacy functions	Rich Felker	-0/+33
	I actually wrote these a month ago but forgot to integrate them. ugly, probably-harmful-to-use functions, but some legacy apps want them...
2012-04-22	add getresuid and getresgid syscall wrappers	Rich Felker	-0/+16

2012-04-16	wordexp must set the we_offs entries of we_wordv to null pointers	Rich Felker	-0/+4

2012-04-16	fix crash in wordfree if we_offs is not initialized by the caller	Rich Felker	-0/+2
	I'm not sure if it's legal for wordexp to modify this field, but this is the only easy/straightforward fix, and applications should not care. if it's an issue, i can work out a different (but more complex) solution later.
2012-03-01	implement a64l and l64a (legacy xsi stuff)	Rich Felker	-0/+26

2012-02-23	fix (hopefully) PTRACE_TRACEME (command 0) argument handling	Rich Felker	-2/+2

2012-02-17	fix get_current_dir_name behavior	Rich Felker	-2/+6

2012-02-17	add get_current_dir_name function	Rich Felker	-0/+12

2012-01-24	add legacy futimes and lutimes functions	Rich Felker	-0/+26
	based on patch by sh4rm4. these functions are deprecated; futimens and utimensat should be used instead in new programs.
2012-01-20	use prlimit syscall for getrlimit/setrlimit	Rich Felker	-4/+14
	this allows the full range of 64-bit limit arguments even on 32-bit systems. fallback to the old syscalls on old kernels that don't support prlimit.
2012-01-20	add prlimit syscall wrapper	Rich Felker	-0/+8

2012-01-18	alias basename to glibc name for it, to meet abi goals	Rich Felker	-0/+3
	note that regardless of the name used, basename is always conformant. it never takes on the bogus gnu behavior, unlike glibc where basename is nonconformant when declared manually without including libgen.h.
2011-09-16	fix ptrace (maybe)	Rich Felker	-1/+8

2011-09-15	implement ptrace syscall wrapper (untested)	Rich Felker	-0/+18

2011-09-13	remove some stray trailing space characters	Rich Felker	-1/+1

2011-07-30	fix some bugs in setxid and update setrlimit to use __synccall	Rich Felker	-2/+27
	setrlimit is supposed to be per-process, not per-thread, but again linux gets it wrong. work around this in userspace. not only is it needed for correctness; setxid also depends on the resource limits for all threads being the same to avoid situations where temporarily unlimiting the limit succeeds in some threads but fails in others.
2011-07-22	check for fd exhaustion in forkpty	Rich Felker	-2/+15
	we cannot report failure after forking, so the idea is to ensure prior to fork that fd 0,1,2 exist. this will prevent dup2 from possibly hitting a resource limit and failing in the child process. fcntl rather than dup2 is used prior to forking to avoid race conditions.
2011-07-22	incorrect check for open failure in openpty function	Rich Felker	-1/+1
	-1, not 0, indicates failure
2011-06-25	wordexp cannot use we_offs unless WRDE_DOOFFS flag is set	Rich Felker	-1/+2
	previously, a potentially-indeterminate value from we_offs was being used, resulting in wrong we_wordc and subsequent crashes in the caller.
2011-06-18	fix memory leak on failure in realpath	Rich Felker	-4/+4

2011-05-29	add useless, obsolescent function ulimit	Rich Felker	-0/+19

2011-04-20	properly create new session/controlling terminal in forkpty	Rich Felker	-1/+4

2011-04-20	implement (nonstandard) forkpty	Rich Felker	-0/+22

2011-04-19	block cancellation in wordexp, handle more errors	Rich Felker	-2/+17

2011-04-19	avoid malloc of potentially-large string in wordexp	Rich Felker	-10/+28

2011-04-18	protect ftw and nftw against cancellation	Rich Felker	-1/+6

2011-04-18	protect syslog against cancellation	Rich Felker	-5/+19
	these functions are allowed to be cancellation points, but then we would have to install cleanup handlers to avoid termination with locks held.
2011-04-17	minimal realpath implementation using /proc	Rich Felker	-0/+43
	clean and simple, but fails when the caller does not have permissions to open the file for reading or when /proc is not available. i may replace this with a full implementation later, possibly leaving this version as an optimization to use when it works.
2011-04-15	remove stupid debug code in wordexp	Rich Felker	-1/+0

2011-04-15	implement wordexp. first try, may be buggy. intended to be safe.	Rich Felker	-0/+128

2011-04-13	simplify syslog, add vsyslog interface (nonstandard)	Rich Felker	-31/+36
	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...
2011-04-13	remove useless SIGPIPE protection from syslog	Rich Felker	-9/+0
	per the standard, SIGPIPE is not generated for SOCK_DGRAM.
2011-04-13	fix syslog (corrected SIGPIPE blocking, and using dgram instead of stream)	Rich Felker	-10/+8
	it actually appears the hacks to block SIGPIPE are probably not necessary, and potentially harmful. if i can confirm this, i'll remove them.
2011-04-13	implement getgrouplist (for initgroups), formerly dummied-outv0.7.8	Rich Felker	-4/+16

2011-04-13	add ptsname_r (nonstandard) and split ptsname (standard) to separate file	Rich Felker	-11/+16
	this eliminates the ugly static buffer in programs that use ptsname_r.
2011-04-12	move bswap functions to static inline in byteswap.h	Rich Felker	-16/+0

2011-04-12	fix broken bswap_32	Rich Felker	-1/+1

2011-04-11	remove ugly warning-suppression hack from crypt - this invokes UB!	Rich Felker	-1/+1

2011-03-25	fix all implicit conversion between signed/unsigned pointers	Rich Felker	-2/+2
	sadly the C language does not specify any such implicit conversion, so this is not a matter of just fixing warnings (as gcc treats it) but actual errors. i would like to revisit a number of these changes and possibly revise the types used to reduce the number of casts required.
2011-03-20	global cleanup to use the new syscall interface	Rich Felker	-20/+8

2011-02-16	fix compile failure: legacy cuserid needs to define feature test	Rich Felker	-0/+1

2011-02-15	fix getrlimit handling on 32-bit systems, and ease porting to 64-bit	Rich Felker	-3/+3

2011-02-12	initial check-in, version 0.5.0v0.5.0	Rich Felker	-0/+3194
