2025-09-17git: allow alias-shadowing deprecated builtinsKristoffer Haugsbakk1-0/+17
git-whatchanged(1) is deprecated and you need to pass `--i-still-use-this` in order to force it to work as before. There are two affected users, or usages: 1. people who use the command in scripts; and 2. people who are used to using it interactively. For (1) the replacement is straightforward.[1] But people in (2) might like the name or be really used to typing it.[3] An obvious first thought is to suggest aliasing `whatchanged` to the git-log(1) equivalent.[1] But this doesn’t work and is awkward since you cannot shadow builtins via aliases. Now you are left in an uncomfortable limbo; your alias won’t work until the command is removed for good. Let’s lift this limitation by allowing *deprecated* builtins to be shadowed by aliases. The only observed demand for aliasing has been for git-whatchanged(1), not for git-pack-redundant(1). But let’s be consistent and treat all deprecated commands the same. [1]: git log --raw --no-merges With a minor caveat: you get different outputs if you happen to have empty commits (no changes)[2] [2]: https://lore.kernel.org/git/20250825085428.GA367101@coredump.intra.peff.net/ [3]: https://lore.kernel.org/git/BL3P221MB0449288C8B0FA448A227FD48833AA@BL3P221MB0449.NAMP221.PROD.OUTLOOK.COM/ Based-on-patch-by: Jeff King <peff@peff.net> Signed-off-by: Kristoffer Haugsbakk <code@khaugsbakk.name> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2025-09-17git: move seen-alias bookkeeping into handle_alias(...)Kristoffer Haugsbakk1-23/+25
We are about to complicate the command handling by allowing *deprecated* builtins to be shadowed by aliases. We need to organize the code in order to facilitate that.[1] The code in the `while(1)` speculatively adds commands to the list before finding out if it’s an alias. Let’s instead move it inside `handle_alias(...)`—where it conceptually belongs anyway—and in turn only run this logic when we have found an alias.[2] [1]: We will do that with an additional call to `handle_alias(1)` inside the loop. *Not* moving this code leaves a blind spot; we will miss alias looping crafted via deprecated builtin names [2]: Also rename the list to a more descriptive name Based-on-patch-by: Jeff King <peff@peff.net> Signed-off-by: Kristoffer Haugsbakk <code@khaugsbakk.name> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2025-09-17git: add `deprecated` category to --list-cmdsKristoffer Haugsbakk1-8/+18
With 145 builtin commands (according to `git --list-cmds=builtins`), users are probably not keeping on top of which ones (if any) are deprecated. Let’s expand the experimental `--list-cmds`[1] to allow users and programs to query for this information. We will also use this in an upcoming commit to implement `is_deprecated_command`. [1]: Using something which is experimental to query for deprecations is perhaps not the most ideal approach, but it is simple to implement and better than having to scan the documentation Acked-by: Patrick Steinhardt <ps@pks.im> Helped-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Kristoffer Haugsbakk <code@khaugsbakk.name> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2025-08-17repo: declare the repo commandLucas Seiki Oshiro1-0/+1
Currently, `git rev-parse` covers a wide range of functionality not directly related to parsing revisions, as its name suggests. Over time, many features like parsing datestrings, options, paths, and others were added to it because there wasn't a more appropriate command to place them. Create a new Git command called `repo`. `git repo` will be the main command for obtaining the information about a repository (such as metadata and metrics). Also declare a subcommand for `repo` called `info`. `git repo info` will bring the functionality of retrieving repository-related information currently returned by `rev-parse`. Add the required documentation and build changes to enable usage of this subcommand.

2025-08-08builtin: also setup gently for --help-allD. Ben Knoble1-1/+1
Git experts often check the help summary of a command to make sure they spell options right when suggesting advice to colleagues. Further, they might check hidden options when responding to queries about deprecated options like git-rebase(1)'s "preserve merges" option. But some commands don't support "--help-all" outside of a git directory. Running (for example) git rebase --help-all outside a directory fails in "setup_git_directory", erroring with the localized form of fatal: not a git repository (or any of the parent directories): .git Like 99caeed05d (Let 'git <command> -h' show usage without a git dir, 2009-11-09), we want to show the "--help-all" output even without a git dir. Make "--help-all" where we expect "-h" to mean "setup_git_directory_gently", and interpose early in the natural place ("show_usage_with_options_if_asked"). Do the same for usage callers with show_usage_if_asked. The exception is merge-recursive, whose help block doesn't use newer APIs. Best-viewed-with: --ignore-space-change Signed-off-by: D.

2025-07-25git: show alias info only with lone -hRené Scharfe1-1/+1
Builtin commands show usage information on stdout if called with -h as their only option, usage.c::show_usage_if_asked() makes sure of that. Aliases show alias information on stderr if called with -h as the first option since a9a60b94cc (git.c: handle_alias: prepend alias info when first argument is -h, 2018-10-09). This is surprising when using aliases for commands that take -h as a normal argument among others, like git grep. Tighten the condition and show the alias information only if -h is the only option given, to be consistent with builtins. It's probably still is a good idea to write to stderr, as an alias command doesn't have to be a builtin and could instead produce output with just -h that might be spoiled by an extra alias info line.

2025-03-03builtin: introduce diff-pairs commandJustin Tobler1-0/+1
Through git-diff(1), a single diff can be generated from a pair of blob revisions directly. Unfortunately, there is not a mechanism to compute batches of specific file pair diffs in a single process. Such a feature is particularly useful on the server-side where diffing between a large set of changes is not feasible all at once due to timeout concerns. To facilitate this, introduce git-diff-pairs(1) which acts as a backend passing its NUL-terminated raw diff format input from stdin through diff machinery to produce various forms of output such as patch or raw. The raw format was originally designed as an interchange format and represents the contents of the diff_queued_diff list making it possible to break the diff pipeline into separate stages. For example, git-diff-tree(1) can be used as a frontend to compute file pairs to queue and feed its raw output to git-diff-pairs(1) to compute patches. With this, batches of diffs can be progressively generated without having to recompute renames or retrieve object context. Something like the following: git diff-tree -r -z -M $old $new | git diff-pairs -p -z should generate the same output as `git diff-tree -p -M`. Furthermore, each line of raw diff formatted input can also be individually fed to a separate git-diff-pairs(1) process and still produce the same output.

2024-11-21help: fix leaking return value from `help_unknown_cmd()`Patrick Steinhardt1-1/+3
While `help_unknown_cmd()` would usually die on an unknown command, it instead returns an autocorrected command when "help.autocorrect" is set. But while the function is declared to return a string constant, it actually returns an allocated string in that case. Callers thus aren't aware that they have to free the string, leading to a memory leak. Fix the function return type to be non-constant and free the returned value at its only callsite. Note that we cannot simply take ownership of `main_cmds.names[0]->name` and then eventually free it. This is because the `struct cmdname` is using a flex array to allocate the name, so the name pointer points into the middle of the structure and thus cannot be freed.

2024-11-21git: refactor builtin handling to use a `struct strvec`Patrick Steinhardt1-35/+31

2024-11-21git: refactor alias handling to use a `struct strvec`Patrick Steinhardt1-26/+32
In `handle_alias()` we use both `argcp` and `argv` as in-out parameters. Callers mostly pass through the static array from `main()`, but once we handle an alias we replace it with an allocated array that may contain some allocated strings. Callers do not handle this scenario at all and thus leak memory. We could in theory handle the lifetime of `argv` in a hacky fashion by letting callers free it in case they see that an alias was handled. But while that would likely work, we still wouldn't be able to easily handle the lifetime of strings referenced by `argv`. Refactor the code to instead use a `struct strvec`, which effectively removes the need for us to manually track lifetimes.

The current code in run_builtin() passes in a repository to the builtin based on whether cmd_struct's option flag has RUN_SETUP. This is incorrect, however, since some builtins that only have RUN_SETUP_GENTLY can potentially take a repository. setup_git_directory_gently() tells us whether or not a command is being run inside of a repository. Use the output of setup_git_directory_gently() to help determine whether or not there is a repository to pass to the builtin. If not, then we just pass NULL. As part of this patch, we need to modify add to check for a NULL repo before calling repo_git_config(), since add -h can be run outside of a repository.

In `handle_builtin()` we may end up creating an ad-hoc argv array in case we see that the command line contains the "--help" parameter. In this case we observe two memory leaks though: - We leak the `struct strvec` itself because we directly exit after calling `run_builtin()`, without bothering about any cleanups. - Even if we free'd that vector we'd end up leaking some of its strings because `run_builtin()` will modify the array.

2024-06-14global: introduce `USE_THE_REPOSITORY_VARIABLE` macroPatrick Steinhardt1-0/+2
Use of the `the_repository` variable is deprecated nowadays, and we slowly but steadily convert the codebase to not use it anymore. Instead, callers should be passing down the repository to work on via parameters. It is hard though to prove that a given code unit does not use this variable anymore. The most trivial case, merely demonstrating that there is no direct use of `the_repository`, is already a bit of a pain during code reviews as the reviewer needs to manually verify claims made by the patch author. The bigger problem though is that we have many interfaces that implicitly rely on `the_repository`. Introduce a new `USE_THE_REPOSITORY_VARIABLE` macro that allows code units to opt into usage of `the_repository`. The intent of this macro is to demonstrate that a certain code unit does not use this variable anymore, and to keep it from new dependencies on it in future changes, be it explicit or implicit For now, the macro only guards `the_repository` itself as well as `the_hash_algo`. There are many more known interfaces where we have an implicit dependency on `the_repository`, but those are not guarded at the current point in time. Over time though, we should start to add guards as required (or even better, just remove them). Define the macro as required in our code units. As expected, most of our code still relies on the global variable. Nearly all of our builtins rely on the variable as there is no way yet to pass `the_repository` to their entry point. For now, declare the macro in "biultin.h" to keep the required changes at least a little bit more contained.

Introduce a new command that allows the user to migrate a repository between ref storage formats. This new command is implemented as part of a new git-refs(1) executable. This is due to two reasons: - There is no good place to put the migration logic in existing commands. git-maintenance(1) felt unwieldy, and git-pack-refs(1) is not the correct place to put it, either. - I had it in my mind to create a new low-level command for accessing refs for quite a while already. git-refs(1) is that command and can over time grow more functionality relating to refs. This should help discoverability by consolidating low-level access to refs into a single executable. As mentioned in the preceding commit that introduces the ref storage format migration logic, the new `git refs migrate` command still has a bunch of restrictions. These restrictions are documented accordingly. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-05-03advice: add --no-advice global optionJames Liu1-2/+7
Advice hints must be disabled individually by setting the relevant advice.* variables to false in the Git configuration. For server-side and scripted usages of Git where hints can be a hindrance, it can be cumbersome to maintain configuration to ensure all advice hints are disabled in perpetuity. This is a particular concern in tests, where new or changed hints can result in failed assertions. Add a --no-advice global option to disable all advice hints from being displayed.

Also do not model how the request is not propagated to subprocesses we spawn (e.g. "git clone --local" that spawns a new process to work in the origin repository, while the original one working in the newly created one) by the "--no-replace-objects" option, as this "do not lazily fetch from the promisor" is more about a per-request debugging aid, not "this repository's promisor should not be relied upon" property specific to a repository.

Sometimes, especially during tests of low level machinery, it is handy to have a way to disable lazy fetching of objects. This allows us to say, for example, "git cat-file -e <object-name>", to see if the object is locally available. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2023-11-26replay: introduce new builtinElijah Newren1-0/+1
For now, this is just a rename from `t/helper/test-fast-rebase.c` into `builtin/replay.c` with minimal changes to make it build appropriately. Let's add a stub documentation and a stub test script though. Subsequent commits will flesh out the capabilities of the new command and make it a more standard regular builtin.

2023-06-21read-cache*.h: move declarations for read-cache.c functions from cache.hElijah Newren1-0/+1
For the functions defined in read-cache.c, move their declarations from cache.h to a new header, read-cache-ll.h. Also move some related inline functions from cache.h to read-cache.h. The purpose of the read-cache-ll.h/read-cache.h split is that about 70% of the sites don't need the inline functions and the extra headers they include.

2023-06-12repository: create disable_replace_refs()Derrick Stolee1-1/+1
Several builtins depend on being able to disable the replace references so we actually operate on each object individually. These currently do so by directly mutating the 'read_replace_refs' global. A future change will move this global into a different place, so it will be necessary to change all of these lines. However, we can simplify that transition by abstracting the purpose of these global assignments with a method call. We will need to keep this read_replace_refs global forever, as we want to make sure that we never use replace refs throughout the life of the process if this method is called. Future changes may present a repository-scoped version of the variable to represent that repository's core.useReplaceRefs config value, but a zero-valued read_replace_refs will always override such a setting.

2023-05-06attr: teach "--attr-source=<tree>" global option to "git"John Cai1-0/+16
Earlier, 47cfc9bd (attr: add flag `--source` to work with tree-ish, 2023-01-14) taught "git check-attr" the "--source=<tree>" option to allow it to read attribute files from a tree-ish, but did so only for the command. Just like "check-attr" users wanted a way to use attributes from a tree-ish and not from the working tree files, users of other commands (like "git diff") would benefit from the same. Undo most of the UI change the commit made, while keeping the internal logic to read attributes from a given tree-ish. Expose the internal logic via a new "--attr-source=<tree>" command line option given to "git", so that it can be used with any git command that runs as part of the main git process. Additionally, add an environment variable GIT_ATTR_SOURCE that is set when --attr-source is passed in, so that subprocesses use the same value for the attributes source tree.

Dozens of files made use of trace and trace2 functions, without explicitly including trace.h or trace2.h. This made it more difficult to find which files could remove a dependence on cache.h.
