Eric Blake 83b1d641 2011-04-27T16:23:45 hash, mgetgroups: drop xalloc dependency Rely on the new xalloc-oversized module to avoid requiring xalloc-die for functions documented as returning NULL on potential allocation overflow. * lib/hash.c (includes): Adjust includes. * lib/mgetgroups.c (includes): Likewise. (xgetgroups): Move... * lib/xgetgroups.c: ...to new file. * modules/xgetgroups: New file, split from... * modules/mgetgroups: ...here. (Depends-on): Add xalloc-oversized. * modules/hash (Depends-on): Likewise. * modules/hash-tests (Depends-on): Drop xalloc. (test_hash_LDADD): Drop unused library. * tests/test-hash.c (main): Break xalloc dependency. (includes): Drop unused include. Signed-off-by: Eric Blake <eblake@redhat.com>
Jim Meyering d60f3b0c 2011-01-01T20:17:23 maint: update almost all copyright ranges to include 2011 Run the new "make update-copyright" rule.
Jim Meyering b2e2010c 2010-01-01T10:31:12 update nearly all FSF copyright year lists to include 2010 Use the same procedure as for 2009, outlined in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/20081
Eric Blake 3e035a5d 2009-12-04T08:26:23 mgetgroups: add xgetgroups, and avoid ENOSYS failures ENOSYS implies that there are no supplemental groups, so we can treat it the same as a return of 0 from getgroups rather than exposing failure to the user. This in turn fixes a crash in coreutils' id, which freed an uninitialized pointer. * lib/mgetgroups.h (xgetgroups): New prototype. * lib/mgetgroups.c (xgetgroups): New wrapper. (mgetgroups): Handle ENOSYS. * modules/mgetgroups (Depends-on): Add realloc. Reported by Scott Harrison <scott.gnu.2009@scottrix.co.uk>. Signed-off-by: Eric Blake <ebb9@byu.net>
Eric Blake 8c4c7e9f 2009-11-12T11:31:52 mgetgroups: new module, taken from coreutils Wrapper function that makes using getgroups/getugroups easier to use. As part of the move from coreutils, convert GETGROUPS_T to gid_t, and allow mgetgroups(NULL,getegid(),&list) as a way to ensure that the effective gid is in the list. * modules/mgetgroups: New file. * lib/mgetgroups.h: Likewise. * lib/mgetgroups.c (mgetgroups): Likewise. * m4/mgetgroups.m4 (gl_MGETGROUPS): Likewise. * MODULES.html.sh (Users and groups): Mention it.
