coreutils/src/group-list.c, branch v7.2

simplify mgetgroups() and avoid -Wsign-compare warnings

2009-01-16T11:06:09Z

* gl/lib/mgetgroups.c: Avoid -Wsign-compare warning by using unsigned types for the parameters of the new function realloc_groupbuf(). mgetgroups() was refactored to use this function rather than explicitly allocating and copying from automatic storage itself. * src/group-list.c: Use int rather than size_t as variable is used in signed comparisons. * src/id.c: ditto.

group-list: avoid compiler warning

2008-10-24T17:44:48Z

* src/group-list.c (print_group_list) [!HAVE_GETGROUPS]: Always return value.

Include only if used.

2008-03-16T18:04:29Z

* src/group-list.c: Don't include . * src/printf.c: Likewise.

groups: don't test printf and putchar calls for failure

They are unnecessary, since we use gnulib's closeout module. * src/group-list.c (print_group): Remove explicit error tests. * src/groups.c (main): Likewise. (write_error): Remove function.

Replace groups.sh with groups.c.

2008-02-13T13:37:22Z

* src/groups.c (main): New file, replacing groups.sh. * src/group-list.c, src/group-list.h: New files, factored out of id.c, implementing the functionality that "id" and "groups" have in common. * src/id.c (print_full_info): Avoid a segfault when trying to print an error message if getgroups fails. (print_group_list): Move to group-list.c. (print_group): Likewise. * man/Makefile.am: When building groups.1, obtain the help text from src/groups.c, not src/groups.sh. (noinst_HEADERS): Add group-list.h. (group): Remove rule. (dist_man_MANS): Remove groups.1. * doc/coreutils.texi (groups: Print group names a user is in): Explain why "groups" and "groups $(id -un)" give different results in existing login sessions after you change the group database. (id: Print user identity): Likewise for "id". * po/POTFILES.in: Add src/group-list.c and src/groups.c. * NEWS: mention this. * AUTHORS: Update.
