Replace bare grep with test_grep in test assertions across the
suite, including sourced test helpers (lib-*.sh, *-tests.sh).
test_grep prints the contents of the file being searched on
failure, making debugging easier than a bare grep which fails
silently.
Only assertion-style greps are converted: grep used as a filter
in pipelines, command substitutions, conditionals, or with
redirected I/O is left as-is with a "# lint-ok" annotation.
Existing '! test_grep' calls are rewritten to 'test_grep !' so
that the diagnostic output is preserved on failure.
test_grep requires the file it reads to exist, so '! grep'
assertions that inspect a file whose presence is conditional need
care. In t5537 the '.git/shallow' file is still present after the
repack (the client remains shallow), so the assertion is
converted like any other. In t1400 the '.git/packed-refs' file
exists only with the files backend, so its check is guarded with a
REFFILES prerequisite; the backend-agnostic 'git show-ref' check
that follows still runs under every backend. In t7450 'git~2' is
the NTFS 8.3 short name of a '..git' file and only exists
when 8.3 short-name generation is enabled, so its check is guarded
with a 'test -f' on the path and uses test_grep inside the guard,
the same shape as t1400 (a plain test_grep would BUG when the
short name is absent).
The conversion was generated using a grep-assertion linter
(greplint.pl, added in the following commit) to identify bare
grep calls at command position. To reproduce, from the t/
directory:
# Step 1: annotate the two data-filter greps (grep produces
# data, not a verdict) so the linter skips them.
sed -i '/grep -vf before commits\.raw/s/$/ # lint-ok: data filter/' \
t5326-multi-pack-bitmaps.sh
sed -i '/grep -E "^\[0-9a-f\].*|| :/s/$/ # lint-ok: data filter/' \
t5702-protocol-v2.sh
# Step 1b: two '! grep' assertions need more than a mechanical
# conversion; handle them by hand before the linter-driven steps
# below so it leaves them alone.
#
# t1400: '.git/packed-refs' is absent under reftable, so guard the
# check with REFFILES (a plain test_grep would BUG on the missing
# file):
#
# git update-ref -d HEAD $B &&
# - ! grep "$m" .git/packed-refs &&
# + if test_have_prereq REFFILES
# + then
# + test_grep ! "$m" .git/packed-refs
# + fi &&
# test_must_fail git show-ref --verify -q $m
#
# t7450: git~2 is an NTFS 8.3 short name that exists only when
# short-name generation is enabled, so guard the check on its
# presence with 'test -f' and note in a comment why the path can
# be absent (a plain test_grep would BUG when it is):
#
# - ! grep gitdir squatting-clone/d/a/git~2
# + if test -f squatting-clone/d/a/git~2
# + then
# + test_grep ! gitdir squatting-clone/d/a/git~2
# + fi
# Step 2: reorder pre-existing '! test_grep' to 'test_grep !'
# (must come before steps 3-4 so greplint does not see them)
sed -i 's/! test_grep/test_grep !/' t0031-lockfile-pid.sh
sed -i 's/! test_grep/test_grep !/' t5300-pack-object.sh
sed -i 's/! test_grep/test_grep !/' t5319-multi-pack-index.sh
# Step 3: convert '! grep' -> 'test_grep !'

Now that the default value for TEST_PASSES_SANITIZE_LEAK is `true` there
is no longer a need to have that variable declared in all of our tests.
Drop it.

Mark all but one tests that match "*gettext*" as passing when git is compiled
with SANITIZE=leak. They'll now be listed as running under the
"GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode (the "linux-leaks" CI
target).
In the case of "t0202-gettext-perl.sh" this isn't very meaningful as
most of the work is on the Perl side, but let's mark it anyway.

Change the skeleton implementation of i18n in Git to one that can show
localized strings to users for our C, Shell and Perl programs using
either GNU libintl or the Solaris gettext implementation.
This new internationalization support is enabled by default. If
gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, Git falls back on its current behavior of
showing interface messages in English. When using the autoconf script
we'll auto-detect if the gettext libraries are installed and act
appropriately.
This change is somewhat large because as well as adding a C, Shell and
Perl i18n interface we're adding a lot of tests for them, and for
those tests to work we need a skeleton PO file to actually test
translations. A minimal Icelandic translation is included for this
purpose. Icelandic includes multi-byte characters which makes it easy
to test various edge cases, and it's a language I happen to
understand.
The rest of the commit message goes into detail about various
sub-parts of this commit.
= Installation
Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git itself.
= Perl
Perl code that's to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by default.
Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.
Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.
I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.
See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for
a further elaboration on this topic.
= Shell
Shell code that's to be localized should use the git-sh-i18n
library. It's basically just a wrapper for the system's gettext.sh.
If gettext.sh isn't available we'll fall back on gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.
If neither are present we'll use a dumb printf(1) fall-through
wrapper.
= About libcharset.h and langinfo.h
We use libcharset to query the character set of the current locale if
it's available. I.e. we'll use it instead of nl_langinfo if
HAVE_LIBCHARSET_H is set.
The GNU gettext manual recommends using langinfo.h's
nl_langinfo(CODESET) to acquire the current character set, but on
systems that have libcharset.h's locale_charset() using the latter is
either saner, or the only option on those systems.
GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either,
but MinGW and some others need to use libcharset.h's locale_charset()
instead.
=Credits
This patch is based on work by Jeff Epler <jepler@unpythonic.net> who
did the initial Makefile / C work, and a lot of comments from the Git
mailing list, including Jonathan Nieder, Jakub Narebski, Johannes
Sixt, Erik Faye-Lund, Peter Krefting, Junio C Hamano, Thomas Rast and
others.
