gettext: avoid using gettext if the locale dir is not present

2023-04-17T19:15:39Z

In cc5e1bf99247 (gettext: avoid initialization if the locale dir is not present, 2018-04-21) Git was taught to avoid a costly gettext start-up when there are not even any localized messages to work with. But we still called `gettext()` and `ngettext()` functions. Which caused a problem in Git for Windows when the libgettext that is consumed from the MSYS2 project stopped using a runtime prefix in https://github.com/msys2/MINGW-packages/pull/10461 Due to that change, we now use an unintialized gettext machinery that might get auto-initialized _using an unintended locale directory_: `C:\mingw64\share\locale`. Let's record the fact when the gettext initialization was skipped, and skip calling the gettext functions accordingly. This addresses CVE-2023-25815. Signed-off-by: Johannes Schindelin

grep: fix multibyte regex handling under macOS

2022-08-26T18:45:52Z

The commit 29de20504e (Makefile: fix default regex settings on Darwin, 2013-05-11) fixed t0070-fundamental.sh under Darwin (macOS) by adopting Git's regex library. However, this library is compiled with NO_MBSUPPORT, which causes git-grep to work incorrectly on multibyte (e.g. UTF-8) files. Current macOS versions pass t0070-fundamental.sh with the native macOS regex library, which also supports multibyte characters. Adjust the Makefile to use the native regex library, and call setlocale(3) to set CTYPE according to the user's preference. The setlocale call is required on all platforms, but in platforms supporting gettext(3), setlocale was called as a side-effect of initializing gettext. Therefore, move the CTYPE setlocale call from gettext.c to common-main.c and the corresponding locale.h include into git-compat-util.h. Thanks to the global initialization of CTYPE setlocale, the test-tool regex command now works correctly with supported multibyte regexes, and is used to set the MB_REGEX test prerequisite by assessing a platform's support for them.

tests: remove support for GIT_TEST_GETTEXT_POISON

2021-01-21T23:50:01Z

This removes the ability to inject "poison" gettext() messages via the GIT_TEST_GETTEXT_POISON special test setup. I initially added this as a compile-time option in bb946bba761 (i18n: add GETTEXT_POISON to simulate unfriendly translator, 2011-02-22), and most recently modified to be toggleable at runtime in 6cdccfce1e0 (i18n: make GETTEXT_POISON a runtime option, 2018-11-08).. The reason for its removal is that the trade-off of maintaining it v.s. what it's getting us has long since flipped. When gettext was integrated in 5e9637c6297 (i18n: add infrastructure for translating Git with gettext, 2011-11-18) there was understandable concern on the Git ML that in marking messages for translation en-masse we'd inadvertently mark plumbing messages. The GETTEXT_POISON facility was a way to smoke those out via our test suite. Nowadays however we're done (or almost entirely done) with any marking of messages for translation. New messages are usually marked by their authors, who'll know whether it makes sense to translate them or not. If not any errors in marking the messages are much more likely to be spotted in review than in the the initial deluge of i18n patches in the 2011-2012 era. So let's just remove this. This leaves the test suite in a state where we still have a lot of test_i18n, C_LOCALE_OUTPUT etc. uses. Subsequent commits will remove those too. The change to t/lib-rebase.sh is a selective revert of the relevant part of f2d17068fd (i18n: rebase-interactive: mark comments of squash for translation, 2016-06-17), and the comment in t/t3406-rebase-message.sh is from c7108bf9ed (i18n: rebase: mark messages for translation, 2012-07-25).

gettext.c: remove/reword a mostly-useless comment

2021-01-11T21:07:33Z

Mostly remove the comment I added 5e9637c6297 (i18n: add infrastructure for translating Git with gettext, 2011-11-18). Since then we had a fix in 9c0495d23e6 (gettext.c: detect the vsnprintf bug at runtime, 2013-12-01) so we're not running with the "set back to C locale" hack on any modern system. So having more than 1/4 of the file taken up by a digression about a glibc bug that mostly doesn't happen to anyone anymore is just a needless distraction. Shorten the comment to make a brief mention of the bug, and where to find more info by looking at the git history for this now-removed comment.

Merge branch 'ab/test-env'

2019-07-25T20:59:20Z

Many GIT_TEST_* environment variables control various aspects of how our tests are run, but a few followed "non-empty is true, empty or unset is false" while others followed the usual "there are a few ways to spell true, like yes, on, etc., and also ways to spell false, like no, off, etc." convention. * ab/test-env: env--helper: mark a file-local symbol as static tests: make GIT_TEST_FAIL_PREREQS a boolean tests: replace test_tristate with "git env--helper" tests README: re-flow a previously changed paragraph tests: make GIT_TEST_GETTEXT_POISON a boolean t6040 test: stop using global "script" variable config.c: refactor die_bad_number() to not call gettext() early env--helper: new undocumented builtin wrapping git_env_*() config tests: simplify include cycle test
