2026-08-13completion: add 'git history' subcommandsVincent Mailhol1-0/+30
Use the parse-options completion helpers for the git history subcommands and their options. All current history subcommands take a revision as their first positional argument, so complete that argument as a revision. Once the revision is present, leave any further positional arguments to subcommand-specific completion. This allows a subcommand to complete another kind of argument, such as the pathspec accepted by git history split or another revision if a future subcommand accepts one.

2026-08-13completion: 'git checkout' completes untracked paths as a last resortJunio C Hamano1-2/+19
We taught 'git checkout' to first try to complete revisions (unless '--' is present on the command line) and, failing that, to complete tracked paths. If this yields nothing, it lets the Bash default, which offers paths in $PWD, kick in. Teach it to complete untracked paths before giving up and letting the Bash default kick in. With this change, $ git -C another-directory checkout un<TAB> finds the 'untracked' file in another-directory and offers it as a completion candidate. Note that this is of somewhat dubious value, as an untracked path by definition does not exist in the index, so checking it out from the index would not work well. Even when used to check out the path from a different branch, it is still of dubious value because it is unlikely that a path tracked in another branch is lying untracked in the working tree, as switching from a branch with the path to a branch without it will normally remove the file in the working tree. A better behavior probably is to detect the tree-ish argument on the command line and offer paths with the given prefix as candidates, but there is no __git_complete_from_tree() helper readily usable, so mark this as #leftoverbits to wait for another day.

2026-08-13completion: complete tracked paths for "git checkout"Junio C Hamano1-0/+39
When completing arguments for "git checkout", _git_checkout() delegates to __git_complete_refs(), which only completes revision references. This is good, as mixing revisions and paths in a single list from which the user can choose is confusing. However, if no reference matches, or if "--" is given, _git_checkout() leaves COMPREPLY empty. Bash then falls back to the default filename completion in $PWD. This fails when "git -C <path>" is used, as $PWD is not the target repository. Update _git_checkout() to use __git_complete_index_file() when "--" is present, or when revision reference completion yields no matching candidates, so that tracked paths are offered as candidates.

2026-08-12completion: complete tracked paths for 'git diff'Junio C Hamano1-0/+40
When completing arguments for 'git diff', _git_diff() delegates to __git_complete_revlist_file(), which only completes revision references. This is good [*], as mixing both revisions and paths in a single list for the user to pick from is simply too confusing. If no reference matches, or if '--' is given, however, _git_diff() leaves COMPREPLY empty. Bash then falls back to default filename completion in $PWD. This fails when 'git -C <path>' is used because $PWD is not the target repository. Update _git_diff() to use __git_complete_index_file() when '--' is present, or when revision reference completion yields no matching candidates, so that tracked paths are offered as candidates. This changes behavior even in the case where '-C <there>' is not used. The new behavior omits untracked paths from suggestions when no revs match the prefix but matching tracked paths exist, which is more useful in the context of 'git diff'. When run outside the working tree of a repository, or when nothing matches from revisions or tracked paths, Bash still falls back to default filename completion in $PWD, so such a use case would be just like completing paths for any 'diff' command, rather than for 'git diff'.

2026-07-19Merge branch 'mm/test-grep-lint'Junio C Hamano1-13/+13
The test suite has been updated to use the 'test_grep' helper instead of bare 'grep' for test assertions, allowing file contents to be printed on failure for easier debugging. A new 'greplint' linter has been introduced to detect and prevent new bare 'grep' assertions from being added to the test suite. * mm/test-grep-lint: t: add greplint to detect bare grep assertions t: convert grep assertions to test_grep t: fix Lexer line count for $() inside double-quoted strings t: extract chainlint's parser into shared module t: fix grep assertions missing file arguments t/README: document test_grep helper
2026-07-06t: convert grep assertions to test_grepMichael Montalbo1-13/+13
Replace bare grep with test_grep in test assertions across the suite, including sourced test helpers (lib-*.sh, *-tests.sh). test_grep prints the contents of the file being searched on failure, making debugging easier than a bare grep which fails silently. Only assertion-style greps are converted: grep used as a filter in pipelines, command substitutions, conditionals, or with redirected I/O is left as-is with a "# lint-ok" annotation. Existing '! test_grep' calls are rewritten to 'test_grep !' so that the diagnostic output is preserved on failure. test_grep requires the file it reads to exist, so '! grep' assertions that inspect a file whose presence is conditional need care. In t5537 the '.git/shallow' file is still present after the repack (the client remains shallow), so the assertion is converted like any other. In t1400 the '.git/packed-refs' file exists only with the files backend, so its check is guarded with a REFFILES prerequisite; the backend-agnostic 'git show-ref' check that follows still runs under every backend. In t7450 'git~2' is the NTFS 8.3 short name of a '..git' file and only exists when 8.3 short-name generation is enabled, so its check is guarded with a 'test -f' on the path and uses test_grep inside the guard, the same shape as t1400 (a plain test_grep would BUG when the short name is absent). The conversion was generated using a grep-assertion linter (greplint.pl, added in the following commit) to identify bare grep calls at command position. To reproduce, from the t/ directory: # Step 1: annotate the two data-filter greps (grep produces # data, not a verdict) so the linter skips them. sed -i '/grep -vf before commits\.raw/s/$/ # 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 !

2026-04-22t9902: fix use of `read` with `set -e`Patrick Steinhardt1-4/+2
In t9902 we're using the `read` builtin to read some values into a variable. This is done by using `-d ""`, which cause us to read until the end of the heredoc. As the read is terminated by EOF, the command will end up returning a non-zero error code. This hasn't been an issue until now as we didn't run with `set -e`, but that'll change in a subsequent commit. Prepare for this change by not using read at all, as we can simply store the multi-line value directly.

To align the name of the configuration variable and the name of the command line option, either one should change name. By changing the name of the option we get the added benefit of having --cover-<TAB> expand to --cover-letter without ambiguity. If the user gives the --cover-letter-format option it would be reasonable to expect that the user wants to generate the cover letter despite not giving --cover-letter.

2026-03-06format-patch: add ability to use alt cover formatMirko Faina1-0/+1
Often when sending patch series there's a need to clarify to the reviewer what's the purpose of said series, since it might be difficult to understand it from reading the commits messages one by one. "git format-patch" provides the useful "--cover-letter" flag to declare if we want it to generate a template for us to use. By default it will generate a "git shortlog" of the changes, which developers find less useful than they'd like, mainly because the shortlog groups commits by author, and gives no obvious chronological order. Give format-patch the ability to specify an alternative format spec through the "--cover-letter-format" option. This option either takes "shortlog", which is the current format, or a format spec prefixed with "log:". Example: git format-patch --cover-letter \ --cover-letter-format="log:[%(count)/%(total)] %s (%an)" HEAD~3 [1/3] this is a commit summary (Mirko Faina) [2/3] this is another commit summary (Mirko Faina) ...

However, the `--no-auto-advance` option does not auto advance, thereby allowing users the option to rework with files.

2026-01-12submodule: introduce extensions.submodulePathConfigAdrian Ratiu1-0/+1
The idea of this extension is to abstract away the submodule gitdir path implementation: everyone is expected to use the config and not worry about how the path is computed internally, either in git or other implementations. With this extension enabled, the submodule.<name>.gitdir repo config becomes the single source of truth for all submodule gitdir paths. The submodule.<name>.gitdir config is added automatically for all new submodules when this extension is enabled. Git will throw an error if the extension is enabled and a config is missing, advising users how to migrate. Migration is manual for now.

This patch compliments the previous commit, where builtins that use add-patch infrastructure now respect diff.context and diff.interHunkContext file configurations. In particular, this patch helps users who don't want to set persistent context configurations or just want a way to override them on a one-time basis, by allowing the relevant builtins to accept corresponding command line options that override the file configurations.

2024-02-12completion: add and use __git_compute_second_level_config_vars_for_sectionPhilippe Blain1-1/+1
In a previous commit we removed some hardcoded config variable names from function __git_complete_config_variable_name in the completion script by introducing a new function, __git_compute_first_level_config_vars_for_section. The remaining hardcoded config variables are "second level" configuration variables, meaning 'branch.<name>.upstream', 'remote.<name>.url', etc. where <name> is a user-defined name. Making use of the new existing --config flag to 'git help', add a new function, __git_compute_second_level_config_vars_for_section. This function takes as argument a config section name and computes the corresponding second-level config variables, i.e. those that contain a '<' which indicates the start of a placeholder. Note that as in __git_compute_first_level_config_vars_for_section added previsouly, we use indirect expansion instead of associative arrays to stay compatible with Bash 3 on which macOS is stuck for licensing reasons. As explained in the previous commit, we use the existing pattern in the completion script of using global variables to cache the list of variables for each section. Use this new function and the variables it defines in __git_complete_config_variable_name to remove hardcoded config variables, and add a test to verify the new function. Use a single 'case' for all sections with second-level variables names, since the code for each of them is now exactly the same.

2024-02-12completion: add and use __git_compute_first_level_config_vars_for_sectionPhilippe Blain1-1/+1
The function __git_complete_config_variable_name in the Bash completion script hardcodes several config variable names. These variables are those in config sections where user-defined names can appear, such as "branch.<name>". These sections are treated first by the case statement, and the two last "catch all" cases are used for other sections, making use of the __git_compute_config_vars and __git_compute_config_sections function, which omit listing any variables containing wildcards or placeholders. Having hardcoded config variables introduces the risk of the completion code becoming out of sync with the actual config variables accepted by Git. To avoid these hardcoded config variables, introduce a new function, __git_compute_first_level_config_vars_for_section, making use of the existing __git_config_vars variable. This function takes as argument a config section name and computes the matching "first level" config variables for that section, i.e. those _not_ containing any placeholder, like 'branch.autoSetupMerge, 'remote.pushDefault', etc. Use this function and the variables it defines in the 'branch.*', 'remote.*' and 'submodule.*' switches of the case statement instead of hardcoding the corresponding config variables. Note that we use indirect expansion to create a variable for each section, instead of using a single associative array indexed by section names, because associative arrays are not supported in Bash 3, on which macOS is stuck for licensing reasons. Use the existing pattern in the completion script of using global variables to cache the list of config variables for each section. The rationale for such caching is explained in eaa4e6ee2a (Speed up bash completion loading, 2009-11-17), and the current approach to using and defining them via 'test -n' is explained in cf0ff02a38 (completion: work around zsh option propagation bug, 2012-02-02). Adjust the name of one of the tests added in the previous commit, reflecting that it now also tests the new function.

2024-02-12completion: complete 'submodule.*' config variablesPhilippe Blain1-0/+29
In the Bash completion script, function __git_complete_config_variable_name completes config variables and has special logic to deal with config variables involving user-defined names, like branch.<name>.* and remote.<name>.*. This special logic is missing for submodule-related config variables. Add the appropriate branches to the case statement, making use of the in-tree '.gitmodules' to list relevant submodules. Add corresponding tests in t9902-completion.sh, making sure we complete both first level submodule config variables as well as second level variables involving submodule names.

2024-02-06completion: bisect: recognize but do not complete view subcommandBritton Leo Kerin1-0/+24
The "view" alias for the visualize subcommand is neither completed nor recognized. It's undesirable to complete it because it's first letters are the same as for visualize, making completion less rather than more efficient without adding much in the way of interface discovery. However, it needs to be recognized in order to enable log option completion for it. Recognize but do not complete the view command by creating and using separate lists of completable_subcommands and all_subcommands. Add tests.

2024-02-06completion: bisect: complete log opts for visualize subcommandBritton Leo Kerin1-0/+15
Arguments passed to the "visualize" subcommand of git-bisect(1) get forwarded to git-log(1). It thus supports the same options as git-log(1) would, but our Bash completion script does not know to handle this. Make completion of porcelain git-log options and option arguments to the visualize subcommand work by calling __git_complete_log_opts when the start of an option to the subcommand is seen (visualize doesn't support any options besides the git-log options).

2024-02-06completion: bisect: complete custom terms and related optionsBritton Leo Kerin1-0/+15
git bisect supports the use of custom terms via the --term-(new|bad) and --term-(old|good) options, but the completion code doesn't know about these options or the new subcommands they define. Add support for these options and the custom subcommands by checking for BISECT_TERMS and adding them to the list of subcommands. Add tests.

2024-02-06completion: tests: always use 'master' for default initial branch nameBritton Leo Kerin1-0/+5
The default initial branch name can normally be configured using the GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME environment variable. However, when testing e.g. <rev> completion it's convenient to know the exact initial branch name that will be used. To achieve that without too much trouble it is considered sufficient to force the default initial branch name to 'master' for all of t9902-completion.sh.
