2008-01-08 Ralf Wildenhues

* tests/tools.at (Syntax of the shell scripts): Likewise.
* tests/m4sh.at (LINENO): Quote $0.
Fix testsuite program wrapper for whitespace in `pwd`.
The problem here is that the usual mantra is that command
variables can contain arguments, thus we cannot just escape
$AUTOCONF, $AUTOM4TE etc. The compromise is to put the
$top_builddir/tests directory early in $PATH, so that the
wrappers are found by their plain name.
* tests/wrapper.as: Put $testdir early in $PATH.
(AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
Proper config.status --file/--header and $srcdir escaping.
* lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
characters in $ac_file_inputs.

Fix Autotest for whitespace in `pwd`.
* lib/autotest/general.m4 (AT_INIT)
:
Quote $at_group_dir.
* tests/autotest.at (whitespace in absolute testdir): New test.
* lib/autom4te.in: Quote @datadir@.
Proper file name escaping in Autoconf programs and Perl modules.
This includes escaping of characters special to the shell
as well as special to Perl, e.g., leading `<' or `>'.
For example, when $file starts with `>', `open ">$file"'
wrongly tries to append to a different file.
* bin/autoconf.as: Fix quoting for autom4te options.

from coreutils, written by Jim Meyering.

2007-11-23 Ralf Wildenhues
* lib/autotest/general.m4 (AT_INIT): For awk line number
extraction script, ensure `$at_group' has a defined value
even for the empty set, and properly quote its usage inside
the awk script.
2007-11-22 Ralf Wildenhues
* doc/autoconf.texi (Shell Functions): New chapter. Document

Fix quoting.
2007-11-19 Ralf Wildenhues
Fix IRIX testsuite debugging failures: $0 in functions.
* lib/autotest/general.m4 (AT_INIT) :
Do not use $0 inside a function, as IRIX sh will set that to the

2007-11-19 Paolo Bonzini
and Ralf Wildenhues
* lib/autotest/general.m4 (at_func_test): Use cached line numbers
to extract test scripts.
(AT_INIT): Extract and cache test script line numbers.
2007-11-19 Ralf Wildenhues
* lib/autotest/general.m4: Revert 2007-11-15 patch and
subsequent fixups; the awk -> here-document conversion trashes
performance too much with AIX sh.
2007-11-18 Ralf Wildenhues
* tests/local.at: Do not test m4, perl with AT_TESTED.
Diagnose and guard against write errors dealing with config.status.
The general idea is this: all write failures from `configure'
writing `config.status' are indicated by $ac_write_error, which
is only checked at the end. This is safe because config.status
code is not executed before the file is complete. Other write
failures, be they inside config.status, or in sub shell/awk
scripts spawned from configure or config.status, typically need
earlier checking, as their results are used right afterwards.
* lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
before writing config.status, check afterwards.
(_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
(_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
Set `ac_write_error' for write failures to config.status. Barf
upon write failures to temporary files.
Adjust note about closing and reopening the here-document.
(_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
(_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
reopening the here-document.
* tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
Ensure `ac_write_error' does not escape into config.status.
Also, add a couple of code paths not yet exercised in the test
suite: a config file with input from stdin, and a config header
output to stdout.
Suggestion for catching write errors by Bruno Haible.
2007-11-17 Ralf Wildenhues
Avoid error with Tru64 awk and testsuite lines with many words.
* lib/autotest/general.m4 (AT_INIT): In the awk script that
reads the testsuite, set the field separator to an unusual value,
in order to not run over the limit of 199 fields. Tru64 4.0D awk
even splits the input if $i, i>0, was never accessed in the script.
Revert 2007-10-17 change.
* TODO: Multiline args in config files and headers mean something
different and are not fixed, see
Report by Stepan Kasal.
* doc/autoconf.texi (Generic Programs): Fix typo.
2007-11-16 Stepan Kasal
AC_*_TOOL does not canonicalize the prefix

Report by Bruno Haible.
Indentation fixups.
* lib/autotest/general.m4 (AT_INIT) : Fix
indentation.
(_AT_CHECK): Use less indentation, to save space.
2007-11-15 Ralf Wildenhues
Add witness macro for @top_build_prefix@ substitution.

2007-11-13 Jim Meyering
Clean up the rule to create "expr".
* tests/Makefile.am (expr): Don't redirect directly to target.
Redirect just once, not for each echo statement.

Don't worry about preprocessor when testing long long.
See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html

(AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
These no longer check for preprocessor flaws.
* lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
Do not check for preprocessor flaws.
2007-11-13 Jim Meyering
Adapt dependencies, now that a version change doesn't modify configure.ac
* GNUmakefile: Remove "make clean" kludge.
* lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not

Don't redirect directly to target.
Use $@, not literal "version.m4".

Add -v option to autoreconf invocation.
Remove the autoreconf-provided INSTALL, so that we regenerate it.
* GNUmakefile (dummy): Remove INSTALL.
Remove racy commands to build scripts in bin/ and tests/.
* man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
are guaranteed to be built, remove the rules that tried to build
them. Before, with a parallel build, these rules could lead to
two processes writing tests/wrapper.in concurrently.
Build in man/ only *after* building in bin/ and tests/.
* Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
in both bin/ and tests/.
Accommodate non-srcdir build-from-checkout.
* build-aux/git-version-gen: Require an additional parameter: $srcdir.
Use git's --git-dir=$srcdir/.git option.
Add quotes, in case tarball_version_file contains shell meta-characters.
* GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
* configure.ac: Pass "." to git-version-gen.
Avoid spurious test failures due to version skew.

writable again for the `stderr' file, and ignore errors due to
the attempt to write configure.lineno.
Report by Patrick Welche.
2007-11-10 Jim Meyering
Generate package.m4 in build-dir, not srcdir.
* tests/Makefile.am (package.m4): Adjust target.
Don't redirect directly to $@.
(CLEANFILES): Add package.m4.
($(TESTSUITE)): Depend on just-built package.m4, not the one
in $(srcdir).
When running $(AUTOTEST), search "." before searching $(srcdir).
Avoid a race condition that would make parallel "distclean" fail.
* tests/Makefile.am (distclean-generic): Replace the default,
automake-provided rule with an identical one, but with an additional
dependency on distclean-local. Simply adding the dependency would
cause automake not to emit the rule at all.
* BUGS: Building with -jN works, now.
Distribute git-version-gen.
* Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
since GNUmakefile is distributed, and requires it for dist* rules.
Remove two more generated files from version control.
* INSTALL: Remove generated file.
* lib/autoscan/autoscan.list: Remove generated file.
2007-11-09 Paul Eggert
* GNUmakefile (PATH): Remove stray apostrophes; they become
part of PATH, which isn't wanted here.
2007-11-09 Ralf Wildenhues
New config files output variable `top_build_prefix'.

function, to parametrize arithmetic with expr vs. the shell.
Use it where possible.
Suggestion by Benoit Sigoure.
2007-11-03 Benoit Sigoure
Adjust the documentation of autotest WRT atlocal.
* doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
when using Automake, to write a rule to produce atlocal, since it's

distributed, not atconfig.in.

so that we use just-built tools when they're available.
Suggestions from Ralf Wildenhues.
2007-10-28 Jim Meyering
Make inter-release --version output more useful.
Now, each unofficial build has a version "number" like 2.61a-19-58dd,
which indicates that it is built using the 19th change set
(in _some_ repository) following the "v2.61a" tag, and that 58dd
is a prefix of the commit SHA1.
* build-aux/git-version-gen: New file.
* configure.ac: Run it to set the version.
(AM_INIT_AUTOMAKE): Don't check NEWS here.
* Makefile.am (dist-hook): Arrange so that .version appears only
in distribution tarballs, never in a checked-out repository.
* .gitignore: Add .version here, too. Just in case.
* tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
not configure.ac, now that the version number changes automatically.
Ensure that $(VERSION) is up to date for dist-related targets.
* GNUmakefile: Arrange to rerun autoconf, if the version reported by
git-version-gen doesn't match $(VERSION), but only for dist targets.
