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/`(.*?)`/\$($1)/g' \
tests/du/long-from-unreadable tests/init.cfg
Exempt lines with '$' 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 $(TESTS).
(TESTS): Add over 300 entries.
[patch by Paul Eggert]
* tests/chmod/c-option: When double-quoting part of a word, prefer
to double-quote the whole word. This is a bit easier to read (at
least for me), and in some cases it avoids a shell bug with Tru64
4.0 sh reported by Nelson H. F. Beebe. For example, instead of
"$abs_srcdir"/../setgid-check we now write
"$abs_srcdir/../setgid-check".
