2007-11-16Port to Solaris 'make' and use a Posixish shell on Solaris.Jim Meyering
* bootstrap.conf (gnulib_modules): Add gnu-make, posix-shell. * build-aux/check.mk (SHELL): Set to $(PREFERABLY_POSIX_SHELL), so that commands can assume Posix syntax. (ENABLE_HARD_ERRORS, TEST_LOGS): Don't use GNU Make's "?=" syntax. (SH_E_WORKAROUND): New macro. (am__check_pre, $(TEST_SUITE_LOG)): Use it. (am__check_pre): Fail if "mkdir" fails. Use $(SHELL) rather than relying on the "#!/bin/sh" in the file, so that tests can use Posix syntax. (am__check_pre, am__tty_colors): Use $$src rather than $$<, to support the Posix-make $(TEST_LOGS) rule. (%.log: %.test, %.log: %$(EXEEXT)): Remove unused inference rules that rely on a GNU Make extension and cause Solaris 'make' to fail. (SUFFIXES): New macro, so that we can use Posix style inference rules. (%.log: %): Use this rule only if GNU_MAKE. Set $$src so that macros can use $$src rather than $$<. (CHECK-FORCE, DEPENDENCY, $(TEST_LOGS)): New macros and rules, which rely only on Posix 'make' semantics, and are used only with non-GNU 'make' implementations. $(TEST_LOGS) invokes 'make' recursively (and a bit inefficiently) to simulate the GNU 'make' rules. (.log.html): Renamed from "%.html: %.log", so that it relies only on Posix 'make' semantics. (check-clean, .PHONY): Do not depend on check-clean-local, since Solaris 'make' complains about nonexistent rules like that. * src/Makefile.am (SUFFIXES): Remove; no longer needed. (groups): Use a specific rule rather than an inference rule that is only instantiated once. The inference-rule approach does not work with Solaris 'make', which gets confused by the "groups: Makefile" line. It's not clear from the Posix spec that Solaris 'make' is buggy here, so instead of worrying about it, rewrite the makefile so that it clearly conforms to Posix. * tests/check.mk (TESTS_ENVIRONMENT): Export PACKAGE_BUGREPORT. GNU 'make' does this automatically for us, but Solaris 'make' doesn't. 2007-11-15 Paul Eggert <eggert@cs.ucla.edu>
2007-11-14Use gnulib's stpncpy module, now required by install.cJim Meyering

2007-11-14Enable gnulib-tool's --with-tests option.Jim Meyering
* bootstrap: After all is done, transform the generated gnulib-tests/gnulib.mk. * bootstrap.conf (gnulib_tool_option_extras): Set it here. * gnulib-tests/Makefile.am: New file. * Makefile.am (SUBDIRS): Add gnulib-tests. * configure.ac (AC_CONFIG_FILES): Add gnulib-tests/Makefile. * m4/jm-macros.m4 (coreutils_MACROS) [ARGMATCH_DIE_DECL]: Omit the "extern " prefix to "void usage ()", so that the macro string value can be used to construct a function definition in gnulib's test-argmatch.c.

2007-07-06setuidgid: set all groups, not just the primary one; mgetgroups: new moduleJim Meyering
I wanted to use the xgetgroups function from id.c, so factored it out and made it into a non-exiting function (hence the "m" prefix rather than "x"). * src/setuidgid.c (main): Use mgetgroups. Include "mgetgroups.h". * src/id.c (xgetgroups): Remove function. Include "mgetgroups.h". (print_group_list): Use mgetgroups, not xgetgroups. * gl/modules/mgetgroups: New module. * gl/lib/mgetgroups.c: New file. mgetgroups is derived from id.c's xgetgroups function. * bootstrap.conf (gnulib_modules): Add mgetgroups. * gl/m4/mgetgroups.m4: New file. * gl/lib/mgetgroups.h: New file.

* bootstrap.conf (gnulib_modules): Don't avoid size_max and xsize modules. While I dislike xsize-style overflow avoidance, maintaining a forked version of e.g., vasnprintf.c was too much work. * lib/printf-parse.c, lib/vasnprintf.c, lib/unicodeio.c: Remove local copies, so we now get these files from gnulib.
2007-04-25* bootstrap.conf (gnulib_modules): Add autobuild.Jim Meyering

2007-03-25Avoid the need for euidaccess and/or lstat on every directory entryPaul Eggert
with 'rm -r dir' (without -f), if we are root, or if we are removing a directory tree that is full of symbolic links. * bootstrap.conf (gnulib_modules): Add write-any-file. * src/copy.c: Include write-any-file.h. (UNWRITABLE): Remove macro, replacing with.... (writable_destination): New function, which uses can_write_any_file to avoid the need for euidaccess when we are privileged. (overwrite_prompt, abandon_move): Use it. * src/remove.c: Include write-any-file.h. (D_TYPE): New macro. (DT_UNKNOWN, DT_DIR, DT_LNK) [!HAVE_STRUCT_DIRENT_D_TYPE]: New macros.

(remove_entry): New arg DIRENT_TYPE_ARG. All callers changed.
2007-03-12Make bootstrap.conf a tiny bit more generic.Jim Meyering

2007-01-29Modify "ls" to sort its data faster, using the new gnulib mpsortPaul Eggert
module rather than qsort. This is particularly a win in environments where strcoll is slow, since mpsort typically calls strcoll less often than qsort does. * bootstrap.conf (gnulib_modules): Add mpsort. * src/ls.c: Include mpsort.h. (sorted_file, sorted_file_alloc): New vars, for a new vector of pointers to the file info, for speed.

(avoid_trashing_input, merge): Change FILES parameter like mergefps and call create_temp instead of create_temp_file. (sort): Call create_temp instead of create_temp_file. Use reap_some. (avoid_trashing_input, merge, sort, main): Adapt to mergefps.

* src/tail.c: Include isapipe.h. (IS_PIPE_LIKE_FILE_TYPE): Remove. (IS_TAILABLE_FILE_TYPE): Just list both FIFOs and sockets as tailable, since this seems to be portable. (main): Use isapipe, to fix a bug on MacOS X reported by Bruno Haible in <http://lists.gnu.org/archive/html/bug-coreutils/2006-08/msg00304.html>.
