* tests: port test-fdutimensat.c to Solaris 8Paul Eggert2010-12-242-1/+13
| | | | | | | | * tests/test-fdutimensat.c (do_fdutimens): Don't assume fdutimensat works with a nonnegative fd and AT_SYMLINK_NOFOLLOW. On Solaris 8, it fails with errno == ENOSYS, because there is no futimens (so it can't use the fd), and there is no lutimens (so it can't implement AT_SYMLINK_NOFOLLOW on symlinks).
* vsnprintf: make more consistent with snprintf; doc fixesPaul Eggert2010-12-236-15/+33
| | | | | | | | | | | * doc/posix-functions/snprintf.texi (snprintf): The workaround for the byte count return problem was promoted from the snprintf-posix to the snprintf module. * doc/posix-functions/vsnprintf.texi (vsnprintf): Likewise. * m4/vsnprintf.m4 (gl_FUNC_VSNPRINTF): Also check gl_SNPRINTF_RETVAL_C99, for consistency with gl_FUNC_SNPRINTF. * tests/test-snprintf.c (main): Check the byte count returned. * tests/test-vsnprintf.c (main): Likewise.

| | | | | | * modules/sigpipe (License): Relax license. Signed-off-by: Eric Blake <eblake@redhat.com>
* doc: document Solaris printf bug with large float precisionsPaul Eggert2010-12-2211-0/+70
| | | | | | | | | | | | | | | | | | | | | * doc/posix-functions/dprintf.texi (dprintf): * doc/posix-functions/fprintf.texi (fprintf): * doc/posix-functions/printf.texi (printf): * doc/posix-functions/snprintf.texi (snprintf): * doc/posix-functions/sprintf.texi (sprintf): * doc/posix-functions/vdprintf.texi (vdprintf): * doc/posix-functions/vfprintf.texi (vfprintf): * doc/posix-functions/vprintf.texi (vprintf): * doc/posix-functions/vsnprintf.texi (vsnprintf): * doc/posix-functions/vsprintf.texi (vsprintf): Mention that these functions mishandle large floating point precisions on Solaris 10. The same bug is also present in Solaris 8, and I assume earlier. This causes "cd gnulib-tests; make check" to fail on Solaris 8 (and I assume, later) when building the latest coreutils, in test-vasprintf-posix's call to my_asprintf (&result, "%.4000f %d", 1.0, 99). I have not checked the wide flavors (e.g., wprintf) so this patch just updates the documentation for the narrow ones.

| | | | | | | | * doc/posix-functions/ttyname_r.texi: Mention the OSF/1 bug. * m4/ttyname_r.m4 (gl_FUNC_TTYNAME_R): Detect the OSF/1 bug. Say "no" instead of "guessing no" when the OSF/1 bug or the Solaris bug is present. * lib/ttyname_r.c (ttyname_r): Update comments.
