Sam Clegg	92eaf255a1	Ensure argv is null terminated. This matches the behavior of populate __environ. See #27	6 years ago
Dan Gohman	6cddc9250b	Implement truncate(2). This adds a simple implementation of truncate in terms of open and ftruncate.	6 years ago
Dan Gohman	256081f628	Move the mode_t macros into their own header. This allows them to be defined by <fcntl.h> as well, as specified by POSIX. This fixes a part of src/api/fcntl.c.	6 years ago
Dan Gohman	861f0d2ec8	Define O_TTY_INIT. Define it to 0, as several popular operating systems ignore this flag. This fixes a part of src/api/fcntl.c.	6 years ago
Dan Gohman	a077330632	Update to libpreopen 8835639f27fc42d32096d59d294a0bbb857dc368. This replaces our custom `unlink` wrapper with an upstream one. We still end up replacing the entire body with local changes, but this makes it easier to see what those changes are. The other change here is a fix to ignore repeated '/'s in paths.	6 years ago
Dan Gohman	60cba39d11	Move the SEEK_* macros into their own header and use it from fcntl.h. POSIX requires fcntl.h to define the SEEK_* macros, so this satisfies that requirement. Also, this allows <stdio.h> to avoid including as much unnecessary content. This fixes one issue with src/api/fcntl.c.	6 years ago
Dan Gohman	1db93d1169	Switch from the cloudlibc inet_pton etc. to the musl versions. These functions aren't specific to the underlying system call interface, so they don't need to be in the "bottom half". This also fixes src/functional/inet_pton.c and src/regression/inet_pton-empty-last-field.c in musl's libc-test.	6 years ago
Dan Gohman	46ce01276f	Don't declare dup in unistd.h. Dup isn't defined in libc.a, so don't declare it.	6 years ago
Dan Gohman	382b944a2e	Rename __wasilibc_rmfileat to __wasilibc_unlinkat. The POSIX terminology is that directories are "removed" while files are "unlinked".	6 years ago
Dan Gohman	124f6a4d0a	Add __restrict qualifiers to the fstatat declaration. This makes it consistent with its definition.	6 years ago
Dan Gohman	07858345bc	Ensure that `environ` is always initialized. Initialize `environ` even if there are no environment variables, so that it alwasy points to a NULL-terminated array even if that array just contains the NULL. This fixes src/functional/env.c.	6 years ago
Dan Gohman	c87e877f88	Move abort.c out of libc-bottom-half and into basics.	6 years ago
vms	d987aad467	use ENOMEM instead of EINVAL, set EINVAL if length == 0	6 years ago
vms	30e5a1fd1f	move to __builtin_add_overflow	6 years ago
vms	ccfe4bda30	code deduplication	6 years ago
vms	4a8d1c7cf5	fix comment to correspond existing coding style	6 years ago
vms	20c48b57c7	fix mmap overflow and some other stuff	6 years ago
Dan Gohman	51969495ee	Define TIME_UTC to be 1. TIME_UTC is the only time base defined by the relevant standards. This change doesn't preclude adding other time bases in the future.	6 years ago
Dan Gohman	1bdb356bef	Define CLOCKS_PER_SEC to have type clock_t. The C standard requires CLOCKS_PER_SEC to have type clock_t.	6 years ago
Dan Gohman	cf366c06d1	Optimize lseek in the `tell` case. `lseek(x, 0, SEEK_CUR)` has no effect other than to return the current file offset. The patch here uses a macro with `__builtin_constant_p` to recognize this case and rewrite it to a library call that uses `fd_tell` rather than `fd_seek`, so that programs that don't need actual seeking don't end up importing `fd_seek`. This is also the first usage of `__wasi_fd_tell` in WASI libc, so this adds it to undefined-symbols.txt.	6 years ago
Dan Gohman	401012952d	Declare getentropy in <sys/random.h> Some systems, such as Darwin, only declare getentropy in <sys/random.h>, so declare it there on WASI too for compatibility. Also, give getentropy the underscore-prefix/weak-symbol treatment, as it's not a standard-reserved identifier.	6 years ago
Dan Gohman	1cbedc6d7e	Implement FD_SET, FD_CLR, etc. Previously, FD_SET and friends were missing their actual definitions. This provides definitions, entirely within the system headers in a way that doesn't need instantiated out-of-line definitions.	6 years ago
Dan Gohman	538937e2c8	Remove capsicum.h; WASI libc doesn't support that API, even internally.	6 years ago
Dan Gohman	49f1a57cb8	Declare getrusage. It's defined publicly in libc, so publicly declare it too.	6 years ago
Dan Gohman	1cc98f27f5	Update to cloudlibc 8835639f27fc42d32096d59d294a0bbb857dc368. There's no functional change here; the only change is the patch I submitted upstream, so we can remove some local changes.	6 years ago
Dan Gohman	65107e782f	Rename README to README.md.	6 years ago
Dan Gohman	e18d69c801	Remove socket.c, which was a stub that always failed with ENOSYS.	6 years ago
Dan Gohman	ab594e4d51	Use the same indentation style as surrounding code.	6 years ago
Dan Gohman	7ba6adfc61	Fix miscellaneous lint warnings.	6 years ago
Dan Gohman	685d014446	Provide a public interface to preopened directory lookups. (#10 ) * Provide a public interface to preopened directory lookups. For users of especially non-C compilers, provide an API for looking up preopened directories. This is used internally in WASI libc to translate from eg. `open` to `openat`, but it can now also be used by user code.	6 years ago
Dan Gohman	320054e84f	WASI libc prototype implementation. This incoporates pieces from musl-libc, cloudlibc, cloudabi, libpreopen, and dlmalloc, as well as a significant amount of new code.	6 years ago
