* strerror_r: fix OpenBSD behavior on 0Eric Blake2011-06-211-14/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OpenBSD treats strerror_r(0,,) as a success, but with a message "Undefined error: 0"; while this is distinct from strerror_r(-1,,) returning "Unknown error: -1", it does not imply success. Meanwhile, if buf is short enough for ERANGE, then we can't use strstr to look for "Unknown" or "Undefined" in the resulting message, like we had been doing for strerror(). Fix this by shifting the burden - now the strerror-override code guarantees that 0 will have an override when needed. * lib/strerror-override.c (strerror_override): Also override 0 when needed. * lib/strerror-override.h (strerror_override): Likewise. * lib/strerror.c (strerror): Simplify, now that 0 override is done earlier. * lib/strerror_r.c (strerror_r): Likewise. * m4/strerror.m4 (gl_FUNC_STRERROR): Split detection of 0 behavior... (gl_FUNC_STRERROR_0): ...into new macro. * m4/strerror_r.m4 (gl_FUNC_STRERROR_R): Replace strerror_r if 0 is overridden. (gl_FUNC_STRERROR_R_WORKS): Avoid extra tests if 0 is broken. * modules/strerror-override (Files): Add strerror.m4. (configure.ac): Also provide override for 0 when needed. * doc/posix-functions/strerror.texi (strerror): Document this. * doc/posix-functions/perror.texi (perror): Likewise.

* strerror_r-posix: fix on MacOSEric Blake2011-06-081-3/+7
| | | | | | | | | | | | | | | | | | | | | MacOS X 10.5 strerror(0) is "Unknown error: 0", which is not distinguished from "Unknown error: -1" for out-of-range. Worse, strerror_r(0,,) is "Undefined error: 0", although strerror_r for all other out-of-range values matches strerror. * m4/strerror.m4 (gl_FUNC_STRERROR): Flush out MacOS bug. * m4/strerror_r.m4 (gl_FUNC_STRERROR_R_WORKS): Likewise, and fix logic bug. * lib/strerror_r.c (strerror_r): Fix the bug. * lib/strerror.c (strerror): Likewise. * doc/posix-functions/strerror_r.texi (strerror_r): Document the problem. * doc/posix-functions/strerror.texi (strerror): Likewise. * doc/posix-functions/perror.texi (perror): Likewise. * tests/test-strerror.c (main): Enhance test. * tests/test-strerror_r.c (main): Likewise.

* strerror: work around FreeBSD bugEric Blake2011-06-061-1/+13
| | | | | | | | | | Breaking strerror away from strerror_r re-exposed the FreeBSD strerror(0) bug. * lib/strerror.c (strerror): Special case 0. Reported by Bruno Haible. Signed-off-by: Eric Blake <eblake@redhat.com>
* strerror: drop strerror_r dependencyEric Blake2011-06-011-1/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the errno module is responsible for introducing replacement errno values, it should also be responsible for translating those new values into strings. And by moving the replacements into a file managed by the errno, we can then break the dependency between strerror and strerror_r, so that strerror no longer drags in multi-threading modules required by strerror_r. Tested on glibc with: gl_cv_header_errno_h_complete=no gl_cv_func_working_strerror=no \ gl_cv_func_strerror_r_works=no ./gnulib-tool --with-tests \ --test strerror strerror_r-posix * lib/strerror_r.c (strerror_r): Move gnulib replacement strings... * lib/strerror-override.c (strerror_override): ...to new file. * lib/strerror-override.h: Add prototype. * lib/strerror-impl.h: Delete. * lib/strerror.c (strerror): New implementation. * modules/errno (Files): Add new files. (configure.ac): Compile new file as appropriate. * modules/strerror (Files): Drop unused file. (Depends-on): Drop strerror_r-posix. * MODULES.html.sh: Document strerror_r-posix.

* relocatable-prog-wrapper: Assume strerror() exists.Bruno Haible2011-05-211-11/+7

(gl_FUNC_STRERROR): Inline it here. Don't define REPLACE_STRERROR as a C macro.
* perror: Avoid clobbering the strerror buffer when possible.Bruno Haible2011-05-191-21/+1
| | | | | | | | | | | * lib/strerror-impl.h: New file, extracted from lib/strerror.c. * lib/strerror.c: Include it. * modules/strerror (Files): Add lib/strerror-impl.h. * lib/perror.c: Include <stdlib.h>, intprops.h, verify.h. (my_strerror): New function, defined through lib/strerror-impl.h. (perror): Use it instead of strerror. * modules/perror (Files): Add lib/strerror-impl.h. (Depends-on): Remove strerror.

| | | | | | | | | * lib/strerror_r.c (strerror_r): Merge the three implementations. Handle gnulib defined errno values here. When strerror() returns NULL or an empty string, return EINVAL. * lib/strerror.c (strerror): Always call strerror_r. Don't handle gnulib defined errno values here. * modules/strerror (Depends-on): Add verify, strerror_r-posix.

| | | | | | | | | | | | | | | | | * lib/strerror.c: Include <string.h> always, to test interface, and to remove the need for the dummy.
