2018-04-03socket: __poll_chkElizabeth Myers1-0/+13
2018-04-03math: implement most of glibc's __*_finite functionsElizabeth Myers1-2/+1090
These are supposed to be specialisations for speed, but these are just faked. Some warnings were added too, if they return infinite values. As a side effect of this change, scalbl is also now implemented. As noted, not all functions are implemented; the big two blockers are an implementation of j0l and y0l; I imagine Bessel functions aren't too widely used, so I doubt that many things will want them. Someone (not it) can implement them later.
2018-04-03GCOMPAT__assert_with_reason: omit format parameterElizabeth Myers1-2/+2
__VA_ARGS__ expects one or more arguments; this is a cheesy hack to allow passing only a format string (which is often all you need for small asserts).
2018-03-16build: allow building with libucontext supportWilliam Pitcock1-0/+4
2018-02-23gnulib: use GCOMPAT__assert_with_reason() instead of bare assert()William Pitcock1-2/+10

2018-01-15readlink: Intercept readlink("/proc/self/exe")Samuel Holland1-0/+85
This allows programs run through gcompat to fork and re-exec themselves. It fixes readlink("/proc/self/exe") to return the executable's absolute path, instead of musl's path. Signed-off-by: Samuel Holland <samuel@sholland.org>
2018-01-15utmp: Implement the reentrant utmp function from LSBSamuel Holland1-0/+14
This takes advantage of the (lack of a) musl implementation for simplicity. Signed-off-by: Samuel Holland <samuel@sholland.org>
2018-01-15unistd: Implement LSB functions plus moreSamuel Holland1-0/+172
On musl pread and pread64 are the same thing. Signed-off-by: Samuel Holland <samuel@sholland.org>

2018-01-15signal: Add a signal function from LSBSamuel Holland1-0/+11
The other unimplemented signal function in LSB is sigreturn, with is not really implementable. Signed-off-by: Samuel Holland <samuel@sholland.org>
2018-01-15netdb: Add protocol and service functions from LSBSamuel Holland1-0/+79

2018-01-15version: Minor improvementsSamuel Holland1-5/+17
* Document functions and sort by name. * Explicitly include stddef.h. Signed-off-by: Samuel Holland <samuel@sholland.org>
2018-01-15string: Clean up, fix bugs, implement LSB plus moreSamuel Holland1-38/+199
* Add all checked string functions from LSB, plus those found in use in other applications. Document those functions from LSB as such. * Use a consistent structure and paramater names for all functions. * Fix multiple off-by-one errors. * Use a less hacky and more optimized rawmemchr. * Sort functions by name. Signed-off-by: Samuel Holland <samuel@sholland.org>
2018-01-15stdlib: Implement most LSB functions plus moreSamuel Holland2-18/+107
* Fix prototype of __realpath_chk. * Add all strto* functions from LSB, plus the ones thata were previously incorrectly in string.c The main missing LSB functions are the reentrant random functions, which should not be used anyway. Signed-off-by: Samuel Holland <samuel@sholland.org>
2018-01-15stdio: Clean up, add all of LSB stdio plus moreSamuel Holland2-81/+232
* Add all (non-wchar) stdio functions from LSB, plus those found in use in other applications. Document those functions from LSB as such. * Use a consistent structure and paramater names for all functions. * flag == 0 means FORTIFY_SOURCE=1, so the implemented checks should be unconditional. * Add all possible checks without parsing the format string. * Move functions from wchar.h to their own appropriately-named file. Signed-off-by: Samuel Holland <samuel@sholland.org>
2018-01-15resource: Minor improvementsSamuel Holland1-4/+5
* Make function pointer static. * Only initialize function pointer once. Signed-off-by: Samuel Holland <samuel@sholland.org>
2018-01-15resolv: Clean up, avoid NULL derefSamuel Holland1-8/+16
* Make comment style consistent with the rest of the project, and remove outdated header name. * Remove "static inline" from functions (this is no longer a header). * Check statp for NULL in res_ninit like in res_nclose. Signed-off-by: Samuel Holland <samuel@sholland.org>
2018-01-15grp: Implement fgetgrent_r/getgrent_rSamuel Holland1-0/+98
Like fgetpwent_r/getpwent_r, these require a deep copy of the structure into the caller-provided buffer. This is nontrivial for the array of strings member. getgrent_r is required by LSB. [NOTE: I'm not too happy with the macro, but it works. Any suggestions?] Signed-off-by: Samuel Holland <samuel@sholland.org>
