Exempt init.sh because it runs before we're assured to have a
shell that groks $(...). Exempt *.mk because "$" would have to
be doubled, and besides, any `...` expression in a .mk file is
almost certainly evaluated before init.sh is run. Finally, also
exempt the perl-based tests, because perl's `...` cannot be
converted to $(...). Do that by running this command:
git grep -l '`.*`' tests \
| grep -Ev 'init\.sh|\.mk$' | xargs grep -Lw perl \
| xargs perl -pi -e 's/`(.*?)`/\$($1)/g'
One minor fix-up change was required after that, due to how
quoting differs:
diff --git a/tests/chmod/equals b/tests/chmod/equals
- expected_perms=$(eval 'echo \$expected_'$dest)
+ expected_perms=$(eval 'echo $expected_'$dest)
Another was to make these required quoting adjustments:
diff --git a/tests/misc/stty b/tests/misc/stty
...
- rev=$(eval echo "\\\$REV_$opt")
+ rev=$(eval echo "\$REV_$opt")
...
- rev1=$(eval echo "\\\$REV_$opt1")
- rev2=$(eval echo "\\\$REV_$opt2")
+ rev1=$(eval echo "\$REV_$opt1")
+ rev2=$(eval echo "\$REV_$opt2")
Also, transform two files that were needlessly excluded above:
(both use perl, but are mostly bourne shell)
perl -pi -e 's/`(.*?)`/\$($1)/g' \
tests/du/long-from-unreadable tests/init.cfg
Relax initial regexp to match more instances, but add a
filter to avoid some invalid conversions. Run this:
git grep -l "\`[^']*'" tests | xargs perl -pi -e '$q=q"'\''";' \
-e '$q="$q\\$q$q"; /(= ?\`|\`expr|\`echo|\Q$q\E)/ and next;' \
-e ' s/\`([^'\''"]*?'\'')/'\''$1/g'
The last disjunct in the above (...) filter is to exempt
any line that contains this string: '\''
With quoting like that, converting a ` to ' is likely to cause trouble,
so we'll handle those manually. Here are three examples where
the exemption is required:
*': `link-to-dir/'\'': hard link not allowed for directory'*) ;;
printf 'creating file `%s'\''\n' $f
'mv: inter-device move failed: `%s'\'' to `%s'\'';'\
Exempt lines with '$' or '=', since those are prone to improper
conversion. Run this:
git grep -l "\`[^']*'" tests \
|xargs perl -pi -e '/[=\$]/ and next;s/\`([^'\''"]*?'\'')/'\''$1/g'
Initially, I did this,
git grep -l srcdir/test-lib.sh|xargs perl -p0i -e '~180-byte script'
but that line would have been much longer than the maximum permitted
by coreutils' commit hook, and wasn't readable besides, so here's a
more readable version:
lhs=$(printf '%s\\n' \
'if test "$VERBOSE" = yes; then' \
' set -x' \
' touch --version' \
'fi' \
'' \
'. $srcdir/test-lib.sh' \
| sed 's/\$/\\\$/g;s/touch/(\\w+)/')
rhs=$(printf '%s\\n' \
'. "${srcdir=.}/init.sh"; path_prepend_ ../src' \
'test "$VERBOSE" = yes && FIXME --version' \
| sed 's/\$/\\\$/g;s/FIXME/\$1/')
git grep -l srcdir/test-lib.sh|xargs perl -p0i -e "s,$lhs,$rhs,"
Run this command to remove the factored-out "fail=0" lines.
perl -ni -e '/^fail=0$/ or print' $(g grep -l '^fail=0$')
* tests/test-lib.sh: Initialize fail=0 here, not in 300+ scripts.
* tests/...: nearly all bourne shell scripts
Suggested by Eric Blake.
* tests/test-lib.sh (Exit): New function by Ralf Wildenhues in automake
http://git.sv.gnu.org/gitweb/?p=automake.git;a=commitdiff;h=20594c08f63
* tests/**: Convert all uses:
This restrictive change converted the vast majority:
git grep -l '^(exit \$fail); exit \$fail$' \
| xargs perl -pi -e 's/'^\(exit \$fail\); exit \$fail$/Exit \$fail/'
And this did the rest, plus a few undesirable ones, so I manually
backed out the changes to ChangeLog-* and build-aux/check.mk:
git grep -l -E '\(exit [^)]+\); exit ' \
| xargs perl -pi -e 's/\(exit (.+?)\); exit \1/Exit $1/'
One side-effect of this change is that "make check" now works even if
you put "." early in your shell's search PATH (don't do that!).
Remove all test-related Makefile.am files, except those generated
by mk-script. Instead, tests/Makefile.am now lists not only the
tests directly under tests/, but also those in tests/*/ that are
not generated by mk-script, e.g., cp/abuse, cp/acl, mv/i-1, etc.
A lot of these changes are like this:
-. $srcdir/../lang-default
+. $top_srcdir/tests/lang-default
-. $srcdir/../test-lib.sh
+. $top_srcdir/tests/test-lib.sh
* configure.ac (AC_CONFIG_FILES): Remove corresponding Makefiles.
* tests/check.mk (vc_exe_in_TESTS): Relax syntax requirements.
* tests/rwx-to-mode: Remove file. Rewritten as...
* tests/test-lib.sh (rwx_to_mode_): ...this new function.
* tests/Makefile.am (EXTRA_DIST): Remove rwx-to-mode.
(SUBDIRS): Remove each dir with a removed Makefile.am.
(EXTRA_DIST): Add $(TESTS).
(TESTS): Add over 300 entries.
* tests/chgrp/basic: Don't let failure by chgrp to set the
group of a symlink make this test fail. Do give a diagnostic.
In the chgrp-no-change-ctime test, add darwin7.9.0 as another
known-failing system.
When failing on some other system, print $host_triplet, too.

due to a known problem, merely warn about it.
Rewrite to avoid testing output of chgrp --verbose and chgrp -c.
Instead, use stat to test file system for desired results, directly.
* tests/chgrp/Makefile.am (TESTS_ENVIRONMENT): Set host_triplet.
`(exit N); exit N'. Otherwise, those many tests could exit with
improper exit status when exiting via e.g., a trapped interrupt.

symlinks, even on hosts where that's not supported.
Test that if -R is specified without -H or L, -h is assumed.
Test that chown() is not optimized away.
group changed, since chgrp now changes unconditionally. This
complicates the sed script a bit. Do not specify --dereference,
since it's the default (and we want to test this). Adjust output
to match the fact that chgrp no longer optimizes the case of
changing a file's group to the same value as before.
Do `set +x' before starting the subshell
from which we invoke chgrp. Otherwise, the output from the
VERBOSE=yes-induced `set -x' would result in spurious differences.
