2012-06-08fix signedness errors in stdint.h constant macrosRich Felker-2/+2
the types of these expressions must match the integer promotions. unsigned 8- and 16-bit values promote to signed int, not unsigned int.
2012-06-07fix sysinfo, try 2. it seems to work this time.Rich Felker-10/+10
2012-06-07sysinfo struct was utter nonsense; no idea where it came from.Rich Felker-4/+3
this broke the busybox "free" utility (memory reporting) and possibly other things like uptime.
2012-06-04_GNU_SOURCE is supposed to imply _LARGEFILE64_SOURCERich Felker-15/+15
this is ugly and stupid, but now that the *64 symbol names exist, a lot of broken GNU software detects them in configure, then either breaks during build due to missing off64_t definition, or attempts to compile without function declarations/prototypes. "fixing" it here is easier than telling everyone to add yet another feature test macro to their builds.
2012-06-02declare environ in unistd.h when _GNU_SOURCE feature test macro is usedRich Felker-0/+1
lots of broken programs expect this, and it's gotten to the point of being a troubleshooting FAQ topic. best to just fix it.
2012-05-28there is no such GNU function fpurge, only __fpurge.Rich Felker-1/+0
no idea where I got the idea fpurge should exist...
2012-05-28add prototype for BSD/GNU stdio *_unlocked extension functionsRich Felker-2/+12
also fix up distinction of what is GNU-only and what's GNU+BSD
2012-05-28remove duplicate lfs64 cruft in stdio.hRich Felker-2/+0
2012-05-28math: fix nextafter definition in tgmath.hnsz-1/+1
2012-05-23debloat jmp_buf in _GNU_SOURCE modeRich Felker-3/+0
i originally made it the same size as the bloated GNU version, which contains space for saved signal mask, but this makes some structures containing jmp_buf become much larger for no benefit. we will never use the signal mask field with plain setjmp; sigsetjmp serves that purpose.
2012-05-22remove everything related to forkallRich Felker-1/+0
i made a best attempt, but the intended semantics of this function are fundamentally contradictory. there is no consistent way to handle ownership of locks when forking a multi-threaded process. the code could have worked by accident for programs that only used normal mutexes and nothing else (since they don't actually store or care about their owner), but that's about it. broken-by-design interfaces that aren't even in glibc (only solaris) don't belong in musl.
2012-05-22some feature test fixes for unistd.hRich Felker-16/+16
2012-05-22_GNU_SOURCE implies all BSD features except ones GNU rejectsRich Felker-1/+1
2012-05-22various header cleanups, some related to _BSD_SOURCE additionRich Felker-17/+9
there is no reason to avoid multiple identical macro definitions; this is perfectly legal C, and even with the maximal warning options enabled, gcc does not issue any warning for it.
2012-05-22bsd_signal is a legacy (removed) XSI function, not needed in _BSD_SOURCERich Felker-4/+1
its only purpose was for use on non-BSD systems that implement sysv semantics for signal() by default.
2012-05-22support _BSD_SOURCE feature test macroRich Felker-41/+126
patch by Isaac Dunham. matched closely (maybe not exact) to glibc's idea of what _BSD_SOURCE should make visible.
2012-05-20move getpass decl to the right placeRich Felker-1/+1
2012-05-14useless lastlog path just to make some stuff happyRich Felker-0/+1
2012-05-14missing limit LOGIN_NAME_MAXRich Felker-0/+1
2012-05-12use __h_errno_location for h_errnoRich Felker-1/+5
we do not bother making h_errno thread-local since the only interfaces that use it are inherently non-thread-safe. but still use the potentially-thread-local ABI to access it just to avoid lock-in.
2012-05-12susv4 removed gethostbyname, etc. legacy cruft.Rich Felker-9/+7
2012-05-12namespace cleanup - NI_* is NOT reserved by netdb.hRich Felker-3/+2
2012-05-12some gnu junk in netdb.hRich Felker-0/+8
2012-05-12fix missing va_list for vsyslogRich Felker-2/+2
2012-05-13search: add tdestroy (gnu extension)nsz-0/+2
2012-05-11add missing IN6_ARE_ADDR_EQUALRich Felker-0/+5
written to avoid multiple conditional jumps and avoid ugly repetitive lines in the header file.
2012-05-10add one more bogus legacy headerRich Felker-0/+9
this one is for program(s|ers) who haven't heard of uint16_t and uint32_t (which are obviously the correct types for use in such situations, as they're the argument/return types for ntohs/htons and ntohl/htonl).
2012-05-10move vsyslog out of SYSLOG_NAMES conditionalRich Felker-2/+4
2012-05-10fix missing parens in bit op macros (param.h)Rich Felker-1/+1
2012-05-10and another bug in setbit, etc. macros..Rich Felker-1/+1
2012-05-10fix typo in sys/param.h that broke setbit, etc. macrosRich Felker-1/+1
this is all junk, but some programs use it.
2012-05-09omit declaration of basename wrongly interpreted as prototype in C++Rich Felker-0/+2
the non-prototype declaration of basename in string.h is an ugly compromise to avoid breaking 2 types of broken software: 1. programs which assume basename is declared in string.h and thus would suffer from dangerous pointer-truncation if an implicit declaration were used. 2. programs which include string.h with _GNU_SOURCE defined but then declare their own prototype for basename using the incorrect GNU signature for the function (which would clash with a correct prototype). however, since C++ does not have non-prototype declarations and interprets them as prototypes for a function with no arguments, we must omit it when compiling C++ code. thankfully, all known broken apps that suffer from the above issues are written in C, not C++.
2012-05-06some extra legacy header stuffRich Felker-0/+32
2012-05-06take byte order from gcc if gcc has defined itRich Felker-0/+4
this only works with gcc 4.6 and later, but it allows us to support non-default endianness on archs like arm, mips, ppc, etc. that can do both without having separate header sets for both variants, and it saves one #include even on fixed-endianness archs like x86.
2012-05-06add isastream (obsolete STREAMS junk)Rich Felker-1/+2
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).
2012-05-05fix definitions of FP_ILOGB constantsRich Felker-2/+2
two issues: (1) the type was wrong (unsigned instead of signed int), and (2) the value of FP_ILOGBNAN should be INT_MIN rather than INT_MAX to match the ABI. this is also much more useful since INT_MAX corresponds to a valid input (infinity). the standard would allow us to set FP_ILOGB0 to -INT_MAX instead of INT_MIN, which would give us distinct values for ilogb(0) and ilogb(NAN), but the benefit seems way too small to justify ignoring the ABI. note that the macro is just a "portable" (to any twos complement system where signed and unsigned int have the same width) way to write INT_MIN without needing limits.h. it's valid to use this method since these macros are not required to work in #if directives.
2012-05-04add *64 junk for sys/*.h headersRich Felker-0/+50
2012-05-04add support for ugly *64 functions with _LARGEFILE64_SOURCERich Felker-0/+68
musl does not support legacy 32-bit-off_t whatsoever. off_t is always 64 bit, and correct programs that use off_t and the standard functions will just work out of the box. (on glibc, they would require -D_FILE_OFFSET_BITS=64 to work.) however, some programs instead define _LARGEFILE64_SOURCE and use alternate versions of all the standard types and functions with "64" appended to their names. we do not want code to actually get linked against these functions (it's ugly and inconsistent), so macros are used instead of prototypes with weak aliases in the library itself. eventually the weak aliases may be added at the library level for the sake of using code that was originally built against glibc, but the macros will still be the desired solution in the headers.
2012-05-03uglify headers for the sake of junk that compiles with gcc -std=c89/-ansiRich Felker-6/+24
2012-05-03add additional compatibility union member for ipv6 addressesRich Felker-0/+2
in6_* is in the reserved namespace, so this is valid
2012-05-01remove minimal linux kernel headersRich Felker-621/+0
these were at best of limited usefulness (for bootstrapping new systems, mainly) and at worst caused real kernel headers to get overwritten when upgrading libc. in case they're needed by anyone, the exact same files are now available in a new git repository: git://git.etalabs.net/mini-lkh
2012-05-01support alternate glibc name pow10 for exp10Rich Felker-0/+3
2012-04-30first try at writing an efficient and "correct" exp10Rich Felker-0/+4
this is a nonstandard function so it's not clear what conditions it should satisfy. my intent is that it be fast and exact for positive integral exponents when the result fits in the destination type, and fast and correctly rounded for small negative integral exponents. otherwise we aim for at most 1ulp error; it seems to differ from pow by at most 1ulp and it's often 2-5 times faster than pow.
2012-04-29add linux-specific unshare syscall wrapperRich Felker-0/+1
2012-04-22implement getusershell, etc. legacy functionsRich Felker-0/+3
I actually wrote these a month ago but forgot to integrate them. ugly, probably-harmful-to-use functions, but some legacy apps want them...
2012-04-22getdtablesize is not standard; move it to its correct spot in unistd.hRich Felker-1/+1
