* version-etc: new yearPaul Eggert2014-12-311-1/+1
| | | | | | * doc/gnulib.texi: * lib/version-etc.c (COPYRIGHT_YEAR): Update copyright date. * all files: Run 'make update-copyright'.
* maint: update copyrightEric Blake2014-01-011-1/+1
| | | | | | I ran 'make update-copyright'. Signed-off-by: Eric Blake <eblake@redhat.com>
* unsetenv etc.: port to Solaris 11 + GNU EmacsPaul Eggert2013-02-111-2/+2
| | | | | | | | | | | * lib/canonicalize-lgpl.c, lib/getaddrinfo.c, lib/getdelim.c: * lib/glob.c, lib/random_r.c, lib/setenv.c, lib/tsearch.c: * lib/unsetenv.c (_GL_ARG_NONNULL): Define before including <config.h>. GNU Emacs's <config.h> includes <stdlib.h> (which is not a great idea but is too painful to fix right now), and without this gnulib change <stdlib.h> was defining _GL_ARG_NONNULL incorrectly when compiling unsetenv.c on Solaris 11. Fix the problem for unsetenv.c, and fix other similar occurrences.

* setenv, unsetenv: work around various bugsEric Blake2009-11-161-1/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX requires setenv(NULL,"",0), setenv("a=b","",0), unsetenv(NULL), and unsetenv("a=b") to fail with EINVAL, but many BSD implementations lack validation. The gnulib replacement for void unsetenv did not do validation, and the replacement for setenv was out of sync with glibc. Also, some BSD implementations of setenv("a","==",1) eat the leading '='. See also some recent Austin Group interpretations on environ: http://austingroupbugs.net/view.php?id=167 http://austingroupbugs.net/view.php?id=185 * lib/setenv.c (setenv) [!HAVE_SETENV]: Resync from glibc. (setenv) [HAVE_SETENV]: Work around bugs. * lib/unsetenv.c (unsetenv) [HAVE_UNSETENV]: Work around bugs. * m4/setenv.m4 (gl_FUNC_SETENV_SEPARATE, gl_FUNC_UNSETENV): Check for bugs. (gl_FUNC_SETENV): Write in terms of gl_FUNC_SETENV_SEPARATE. * m4/environ.m4 (gl_ENVIRON): Avoid expand-before-require. * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Update defaults. * modules/stdlib (Makefile.am): Update substitutions. * lib/stdlib.in.h (setenv, unsetenv): Update prototypes. * doc/posix-functions/setenv.texi (setenv): Document the bugs. * doc/posix-functions/unsetenv.texi (unsetenv): Likewise. * modules/setenv-tests: New test. * modules/unsetenv-tests: Likewise. * tests/test-setenv.c: New file. * tests/test-unsetenv.c: Likewise.
