2021-10-21git-sh-setup: remove "sane_grep", it's not needed anymoreLibravatar Ævar Arnfjörð Bjarmason1-4/+0
Remove the sane_grep() shell function in git-sh-setup. The two reasons for why it existed don't apply anymore: 1. It was added due to GNU grep supporting GREP_OPTIONS. See e1622bfcbad (Protect scripted Porcelains from GREP_OPTIONS insanity, 2009-11-23). Newer versions of GNU grep ignore that, but even on older versions its existence won't matter, none of these sane_grep() uses care about grep's output, they're merely using it to check if a string exists in a file or stream. We also don't care about the "LC_ALL=C" that "sane_grep" was using, these greps for fixed or ASCII strings will behave the same under any locale. 2. The SANE_TEXT_GREP added in 71b401032b9 (sane_grep: pass "-a" if grep accepts it, 2016-03-08) isn't needed either, none of these grep uses deal with binary data.

2021-10-21git-sh-setup: remove unused sane_egrep() functionLibravatar Ævar Arnfjörð Bjarmason1-4/+0
The is_zero_oid() function in git-submodule.sh has not been used since e83e3333b57 (submodule: port submodule subcommand 'summary' from shell to C, 2020-08-13), so we can remove it, and the sane_egrep() function, dead is_zero_oid() was the only function which still referenced it. Unlike some other functions in git-sh-setup.sh, this function has not been documented in git-sh-setup(1), so per [1] it should be OK to remove it. I'm still unclear about the future of some of the other functions[2], but any questions in that area should not apply here. 1. https://lore.kernel.org/git/xmqqr1dtgnn8.fsf@gitster.g/ 1. https://lore.kernel.org/git/87tuiwjfvi.fsf@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Remove the "pull with rebase" message previously used by the git-pull.sh script, which was removed in 49eb8d39c78 (Remove contrib/examples/*, 2018-03-25). Even if some out-of-tree user copy/pasted the old git-pull.sh code, and relied on passing it a "pull with rebase" argument, we'll fall back on the "*" case here, they just won't get the "pull with rebase" part of their message translated. I don't think it's likely that anyone out-of-tree relied on that, but I'm being conservative here per the discussion that can be found upthread of [1]. 1. https://lore.kernel.org/git/87tuiwjfvi.fsf@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-03-07stash: optionally use the scripted version againLibravatar Johannes Schindelin1-0/+1
We recently converted the `git stash` command from Unix shell scripts to builtins. Let's end users a way out when they discover a bug in the builtin command: `stash.useBuiltin`. As the file name `git-stash` is already in use, let's rename the scripted backend to `git-legacy-stash`. To make the test suite pass with `stash.useBuiltin=false`, this commit also backports rudimentary support for `-q` (but only *just* enough to appease the test suite), and adds a super-ugly hack to force exit code 129 for `git stash -h`.

2016-06-19sh-setup: enclose setting of ${VAR=default} in double-quotesLibravatar LE Manh Cuong1-3/+3
We often make sure an environment variable is set to something, either set by the user (in which case we do not molest it) or set it to our default value (otherwise), with : ${VAR=default value} i.e. running the no-op command ":" with ${VAR} as its parameters (or the default value we supply), relying on that ":" is a no-op. This pattern, even though it is no-op from correctness point of view, still can be expensive if the existing value in VAR has shell glob (because they will be expanded against filesystem entities) and IFS whitespaces (because the value need to be split into multiple parameters). Our invocation of ":" command does not care if the parameter given to it is after the value in VAR goes through these processing. Enclosing the whole thing in double-quote, i.e. : "${VAR=default value}" avoids paying the unnecessary cost, so let's do so.

Positional arguments, such as $0, $1, etc, need to be stored on shell variables for use in translatable strings, according to gettext manual [1]. Add git-sh-setup.sh to LOCALIZED_SH variable in Makefile to enable extraction of string marked for translation by xgettext. Source git-sh-i18n in git-sh-setup.sh for gettext support. git-sh-setup.sh is a shell library to be sourced by other shell scripts. In order to avoid other scripts from sourcing git-sh-i18n twice, remove line that sources it from them. Not sourcing git-sh-i18n in any script that uses gettext would lead to failure due to, for instance, gettextln not being found.

2014-05-07pager: remove 'S' from $LESS by defaultLibravatar Matthieu Moy1-1/+1
By default, Git used to set $LESS to -FRSX if $LESS was not set by the user. The FRX flags actually make sense for Git (F and X because sometimes the output Git pipes to less is short, and R because Git pipes colored output). The S flag (chop long lines), on the other hand, is not related to Git and is a matter of user preference. Git should not decide for the user to change LESS's default. More specifically, the S flag harms users who review untrusted code within a pager, since a patch looking like: -old code; +new good code; [... lots of tabs ...] malicious code; would appear identical to: -old code; +new good code; Users who prefer the old behavior can still set the $LESS environment variable to -FRSX explicitly, or set core.pager to 'less -S'. The documentation in config.txt is made a bit longer to keep both an example setting the 'S' flag (needed to recover the old behavior) and an example showing how to unset a flag set by Git.

On systems with lv configured as the preferred pager (i.e., DEFAULT_PAGER=lv at build time, or PAGER=lv exported in the environment) git commands that use color show control codes instead of color in the pager: $ git diff ^[[1mdiff --git a/.mailfilter b/.mailfilter^[[m ^[[1mindex aa4f0b2..17e113e 100644^[[m ^[[1m--- a/.mailfilter^[[m ^[[1m+++ b/.mailfilter^[[m ^[[36m@@ -1,11 +1,58 @@^[[m "less" avoids this problem because git uses the LESS environment variable to pass the -R option ('output ANSI color escapes in raw form') by default. Use the LV environment variable to pass 'lv' the -c option ('allow ANSI escape sequences for text decoration / color') to fix it for lv, too. Noticed when the default value for color.ui flipped to 'auto' in v1.8.4-rc0~36^2~1 (2013-06-10).

2013-11-26remove #!interpreter line from shell librariesLibravatar Jonathan Nieder1-6/+3
In a shell snippet meant to be sourced by other shell scripts, an opening #! line does more harm than good. The harm: - When the shell library is sourced, the interpreter and options from the #! line are not used. Specifying a particular shell can confuse the reader into thinking it is safe for the shell library to rely on idiosyncrasies of that shell. - Using #! instead of a plain comment drops a helpful visual clue that this is a shell library and not a self-contained script. - Tools such as lintian can use a #! line to tell when an installation script has failed by forgetting to set a script executable. This check does not work if shell libraries also start with a #! line. The good: - Text editors notice the #! line and use it for syntax highlighting if you try to edit the installed scripts (without ".sh" suffix) in place. The use of the #! for file type detection is not needed because Git's shell libraries are meant to be edited in source form (with ".sh" suffix). Replace the opening #! lines with comments. This involves tweaking the test harness's valgrind support to find shell libraries by looking for "# " in the first line instead of "#!" (see v1.7.6-rc3~7, 2011-06-17). Suggested by Russ Allbery through lintian. Thanks to Jeff King and Clemens Buchacher for further analysis. Tested by searching for non-executable scripts with #! line: find . -name .git -prune -o -type f -not -executable | while read file do read line <"$file" case $line in '#!'*) echo "$file" ;; esac done The only remaining scripts found are templates for shell scripts (unimplemented.sh, wrap-for-bin.sh) and sample input used in tests (t/t4034/perl/{pre,post}).

2013-06-19setup_reflog_action: document the rules for using GIT_REFLOG_ACTIONLibravatar Junio C Hamano1-0/+34
The set_reflog_action helper (in git-sh-setup) is designed to be used once at the very top of a program, like this in "git am", for example: set_reflog_action am The helper function sets the given string to GIT_REFLOG_ACTION only when GIT_REFLOG_ACTION is not yet set. Thanks to this, "git am", when run as the top-level program, will use "am" in GIT_REFLOG_ACTION and the reflog entries made by whatever it does will record the updates of refs done by "am". Because of the conditional assignment, when "git am" is run as a subprogram (i.e. an implementation detail) of "git rebase" that already sets GIT_REFLOG_ACTION to its own name, the call in "git am" to the helper function at the beginning will *not* have any effect. So "git rebase" can do this: set_reflog_action rebase ... do its own preparation, like checking out "onto" commit ... decide to do "format-patch" to "am" pipeline git format-patch --stdout >mbox git am mbox and the reflog entries made inside "git am" invocation will say "rebase", not "am". Calls to "git" commands that update refs would use GIT_REFLOG_ACTION to record who did that update. Most such calls in scripted Porcelains do not define custom reflog message and rely on GIT_REFLOG_ACTION to contain its (or its caller's, when it is called as a subprogram) name. If a scripted Porcelain wants to record a custom reflog message for a single invocation of "git" command (e.g. when "git rebase" uses "git checkout" to detach HEAD at the commit a series is to be replayed on), it needs to set GIT_REFLOG_ACTION to the custom message and export it while calling the "git" command, but such an assignment must be restricted to that single "git" invocation and should not be left behind to affect later codepath. Document the rules to avoid future confusion. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-03-13mergetools/p4merge: create a base if none availableLibravatar Kevin Bracey1-0/+12
Originally, with no base, Git gave P4Merge $LOCAL as a dummy base: p4merge "$LOCAL" "$LOCAL" "$REMOTE" "$MERGED" Commit 0a0ec7bd changed this to: p4merge "empty file" "$LOCAL" "$REMOTE" "$MERGED" to avoid the problem of being unable to save in some circumstances with similar inputs. Unfortunately this approach produces much worse results on differing inputs. P4Merge really regards the blank file as the base, and once you have just a couple of differences between the two branches you end up with one a massive full-file conflict. The 3-way diff is not readable, and you have to invoke "difftool MERGE_HEAD HEAD" manually to get a useful view. The original approach appears to have invoked special 2-way merge behaviour in P4Merge that occurs only if the base filename is "" or equal to the left input. You get a good visual comparison, and it does not auto-resolve differences. (Normally if one branch matched the base, it would autoresolve to the other branch). But there appears to be no way of getting this 2-way behaviour and being able to reliably save. Having base==left appears to be triggering other assumptions. There are tricks the user can use to force the save icon on, but it's not intuitive. So we now follow a suggestion given in the original patch's discussion: generate a virtual base, consisting of the lines common to the two branches. This is the same as the technique used in resolve and octopus merges, so we relocate that code to a shared function. Note that if there are no differences at the same location, this technique can lead to automatic resolution without conflict, combining everything from the 2 files. As with the other merges using this technique, we assume the user will inspect the result before saving.

When the user exports a non-default IFS without HT, scripts that rely on being able to parse "ls-files -s | while read a b c..." start to fail. Protect them from such a misconfiguration. * jc/maint-protect-sh-from-ifs: sh-setup: protect from exported IFS
2012-08-08sh-setup: protect from exported IFSLibravatar Junio C Hamano1-0/+4
Many scripted Porcelains rely on being able to split words at the default $IFS characters, i.e. SP, HT and LF. If the user exports a non-default IFS to the environment, what they read from plumbing commands such as ls-files that use HT to delimit fields may not be split in the way we expect. Protect outselves by resetting it, just like we do so against CDPATH exported to the environment. Noticed by Andrew Dranse <adranse@oanda.com>. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-05-16git-sh-setup: define workaround wrappers before they are usedLibravatar Junio C Hamano1-20/+21
Recently we tweaked this scriptlet to let mingw port redefine "pwd" to always return Windows-style path, but the code to do so came after the first use of "pwd" to set up $GIT_DIR shell variable. Move the block to define these workaround wrappers, so that everything everything that executes when the scriptlet is dot-sourced uses the replacements.

2012-02-03parse_date(): '@' prefix forces git-timestampLibravatar Junio C Hamano1-1/+1
The only place that the issue this series addresses was observed where we read "cat-file commit" output and put it in GIT_AUTHOR_DATE in order to replay a commit with an ancient timestamp. With the previous patch alone, "git commit --date='20100917 +0900'" can be misinterpreted to mean an ancient timestamp, not September in year 2010. Guard this codepath by requring an extra '@' in front of the raw git timestamp on the parsing side. This of course needs to be compensated by updating get_author_ident_from_commit and the code for "git commit --amend" to prepend '@' to the string read from the existing commit in the GIT_AUTHOR_DATE environment variable.

2011-10-05use -h for synopsis and --help for manpage consistentlyLibravatar Clemens Buchacher1-1/+1
A few scripted Porcelain implementations pretend as if the routine to show their own help messages are triggered upon "git cmd --help", but a command line parser of "git" will hijack such a request and shows the manpage for the cmd subcommand. Leaving the code to handle such input is simply misleading. Signed-off-by: Clemens Buchacher <drizzd@aon.at> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-05-24require-work-tree wants more than what its name saysLibravatar Junio C Hamano1-0/+7
Somebody tried "git pull" from a random place completely outside the work tree, while exporting GIT_DIR and GIT_WORK_TREE that are set to correct places, e.g. GIT_WORK_TREE=$HOME/git.git GIT_DIR=$GIT_WORK_TREE/.git export GIT_WORK_TREE GIT_DIR cd /tmp git pull At the beginning of git-pull, we check "require-work-tree" and then "cd-to-toplevel". I _think_ the original intention when I wrote the command was "we MUST have a work tree, our $(cwd) might not be at the top-level directory of it", and no stronger than that. That check is a very sensible thing to do before doing cd-to-toplevel. We check that the place we would want to go exists, and then go there. But the implementation of require_work_tree we have today is quite different. I don't have energy to dig the history, but currently it says: test "$(git rev-parse --is-inside-work-tree 2>/dev/null)" = true || die "fatal: $0 cannot be used without a working tree." Which is completely bogus. Even though we may happen to be just outside of it right now, we may have a working tree that we can cd_to_toplevel back to. Add a function "require_work_tree_exists" that implements the check this function originally intended (this is so that third-party scripts that rely on the current behaviour do not have to get broken). For now, update _no_ in-tree scripts, not even "git pull", as nobody on the list seems to really care about the above corner case workflow that triggered this. Scripts can be updated after vetting that they do want the "we want to make sure the place we are going to go actually exists" semantics. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-10-28Porcelain scripts: Rewrite cryptic "needs update" error messageLibravatar Ramkumar Ramachandra1-0/+29
Although Git interally has the facility to differentiate between porcelain and plubmbing commands and appropriately print errors, several shell scripts invoke plubming commands triggering cryptic plumbing errors to be displayed on a porcelain interface. This patch replaces the "needs update" message in git-pull and git-rebase, when `git update-index` is run, with a more friendly message.
