Reduce dependency on `the_repository` in add-patch.c file. * sp/add-patch-with-fewer-the-repository: add-patch: use repository instance from add_i_state instead of the_repository
2026-03-17add-patch: use repository instance from add_i_state instead of the_repositoryShreyansh Paliwal
Functions parse_diff(), edit_hunk_manually() and patch_update_file() use the_repository even though a repository instance is already available via struct add_i_state s which is defined in struct add_p_state *s. Use 's->s.r' instead of the_repository to avoid relying on global state. All callers pass a valid add_p_state and this does not change any behavior. This aligns with the ongoing effort to reduce usage of the_repository global state.

2026-03-03add-patch: allow disabling editing of hunksPatrick Steinhardt
The "add-patch" mode allows the user to edit hunks to apply custom changes. This is incompatible with a new `git history split` command that we're about to introduce in a subsequent commit, so we need a way to disable this mode. Add a new flag to disable editing hunks.

2026-03-03add-patch: add support for in-memory index patchingPatrick Steinhardt
With `run_add_p()` callers have the ability to apply changes from a specific revision to a repository's index. This infra supports several different modes, like for example applying changes to the index, working tree or both. One feature that is missing though is the ability to apply changes to an in-memory index different from the repository's index. Add a new function `run_add_p_index()` to plug this gap. This new function will be used in a subsequent commit. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2026-03-03add-patch: remove dependency on "add-interactive" subsystemPatrick Steinhardt
With the preceding commit we have split out interactive configuration that is used by both "git add -p" and "git add -i". But we still initialize that configuration in the "add -p" subsystem by calling `init_add_i_state()`, even though we only do so to initialize the interactive configuration as well as a repository pointer. Stop doing so and instead store and initialize the interactive configuration in `struct add_p_state` directly.

2026-03-03add-patch: split out `struct interactive_options`Patrick Steinhardt
The `struct add_p_opt` is reused both by our infra for "git add -p" and "git add -i". Users of `run_add_i()` for example are expected to pass `struct add_p_opt`. This is somewhat confusing and raises the question of which options apply to what part of the stack. But things are even more confusing than that: while callers are expected to pass in `struct add_p_opt`, these options ultimately get used to initialize a `struct add_i_state` that is used by both subsystems. So we are basically going full circle here. Refactor the code and split out a new `struct interactive_options` that hosts common options used by both. These options are then applied to a `struct interactive_config` that hosts common configuration. This refactoring doesn't yet fully detangle the two subsystems from one another, as we still end up calling `init_add_i_state()` in the "git add -p" subsystem. This will be fixed in a subsequent commit. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2026-02-17add-patch: allow interfile navigation when selecting hunksAbraham Samuel Adekunle
After deciding on all hunks in a file, the interactive session advances automatically to the next file if there is another, or the process ends. Now using the `--no-auto-advance` flag with `--patch`, the process does not advance automatically. A user can choose to go to the next file by pressing '>' or the previous file by pressing '<', before or after deciding on all hunks in the current file. After all hunks have been decided in a file, the user can still rework with the file by applying the options available in the permit set for that hunk, and after all the decisions, the user presses 'q' to submit. After all hunks have been decided, the user can press '?' which will show the hunk selection summary in the help patch remainder text including the total hunks, number of hunks marked for use and number of hunks marked for skip. This feature is enabled by passing the `--no-auto-advance` flag to `--patch` option of the subcommands add, stash, reset, and checkout.

When the flag `--no-auto-advance` is used with `--patch`, if the user has decided `USE` on a hunk in a file, goes to another file, and then returns to this file and changes the previous decision on the hunk to `SKIP`, because the patch has already been applied, the last decision is not registered and the now SKIPPED hunk is still applied. Move the logic for applying patches into a function so that we can reuse this logic to implement the all or non application of the patches after the user is done with the hunk selection.

The function `patch_update_file()` takes the add_p_state struct pointer and the current `struct file_diff` pointer and returns an int. When using the `--no-auto-advance` flag, we want to be able to request the next or previous file from the caller. Modify the function signature to instead take the index of the current `file_diff` and the `add_p_state` struct pointer so that we can compute the `file_diff` from the index while also having access to the file index.

2026-02-05global: constify some pointers that are not written toCollin Funk
The recent glibc 2.43 release had the following change listed in its NEWS file: For ISO C23, the functions bsearch, memchr, strchr, strpbrk, strrchr, strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr that return pointers into their input arrays now have definitions as macros that return a pointer to a const-qualified type when the input argument is a pointer to a const-qualified type. When compiling with GCC 15, which defaults to -std=gnu23, this causes many warnings like this: merge-ort.c: In function ‘apply_directory_rename_modifications’: merge-ort.c:2734:36: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] 2734 | char *last_slash = strrchr(cur_path, '/'); | ^~~~~~~ This patch fixes the more obvious ones by making them const when we do not write to the returned pointer.

Options a and d stage and unstage all undecided hunks towards the bottom of the array of hunks, respectively, and then roll over to the very first hunk.

2025-10-06add-patch: let options y, n, j, and e roll over to next undecidedRené Scharfe
The options y, n, and e mark the current hunk as decided. If there's another undecided hunk towards the bottom of the hunk array they go there. If there isn't, but there is another undecided hunk towards the top then they go to the very first hunk, no matter if it has already been decided on. The option j does basically the same move. Technically it is not allowed if there's no undecided hunk towards the bottom, but the variable "permitted" is never reset, so this permission is retained from the very first hunk. That may a bug, but this behavior is at least consistent with y, n, and e and arguably more useful than refusing to move. Improve the roll-over behavior of these four options by moving to the first undecided hunk instead of hunk 1, consistent with what they do when not rolling over. Also adjust the error message for j, as it will only be shown if there's no other undecided hunk in either direction.

The variable "permitted" is not reset after moving to a different hunk, so it only accumulates permission and doesn't necessarily reflect those of the current hunk. This may be a bug, but is actually useful with the option J, which can be used at the last hunk to roll over to the first hunk. Make this particular behavior official.

2025-09-25add-patch: update hunk splitability after editingPhillip Wood
If, when the user edits a hunk, they change deletion lines into context lines or vice versa, then the number of hunks that the edited hunk can be split into may differ from the unedited hunk. This means that so we should recalculate `hunk->splittable_into` after the hunk has been edited. In practice users are unlikely to hit this bug as it is doubtful that a user who has edited a hunk will split it afterwards.

2025-09-25add -p: mark split hunks as undecidedPhillip Wood
When a hunk is split, each of the new hunks inherits whether it is selected or not from the original hunk. If a selected hunk is split all of the new hunks are marked as "selected" and the user is only prompted with the first of the split hunks. The user is not asked whether or not they wish to select the rest of the new hunks. This means that if they wish to deselect any of the new hunks apart from the first one they have to navigate back to the hunk they want to deselect before they can deselect it. This is unfortunate as the user is presumably splitting the original hunk because they only want to select some sub-set of it. Instead mark all the new hunks as "undecided" so that the user is prompted whether they wish to select each one in turn. In the case where the user only wants to change the selection of the first of the split hunks they will now have to do more work re-selecting the remaining split hunks. However, changing the selection of any of the other newly created hunks is now much simpler as the user no-longer has to navigate back to them in order to change their selected state.

2025-09-08add-interactive: respect color.diff for diff coloringJeff King
The old perl git-add--interactive.perl script used the color.diff config option to decide whether to color diffs (and if not set, it fell back to the value of color.ui via git-config's --get-colorbool option). When we switched to the builtin version, this was lost: we respect only color.ui. So for example: git -c color.diff=false add -p would color the diff, even when it should not. The culprit is this line in add-interactive.c's parse_diff(): if (want_color_fd(1, -1)) That "-1" means "no config has been set", which causes it to fall back to the color.ui setting. We should instead be passing the value of color.diff. But the problem is that we never even parse that config option! Instead the builtin interactive code parses only the value of color.interactive, which is used for prompts and other messages. One could perhaps argue that this should cover interactive diff coloring, too, but historically it did not. The perl script treated color.interactive and color.diff separately. So we should grab the values for both, keeping separate fields in our add_i_state variable, rather than a single use_color field. We also load individual color slots (e.g., color.interactive.prompt), leaving them as the empty string when color is disabled. This happens via the init_color() helper in add-interactive, which checks that use_color field. Now that there are two such fields, we need to pass the appropriate one for each color. The colors are mostly easy to divide up; color.interactive.* follows color.interactive, and color.diff.* follows color.diff. But the "reset" color is tricky. It is used for both types of coloring, but the two can be configured independently. So we introduce two separate reset colors, and use each in the appropriate spot. There are two new tests. The first enables interactive prompt colors but disables color.diff. We should see a colored prompt but not a colored diff, showing that we are now respecting color.diff (and not color.interactive or color.ui). The second does the opposite. We disable color.interactive but turn on color.diff with a custom fragment color. When we split a hunk, the interactive code has to re-color the hunk header, which lets us check that we correctly loaded the color.diff.frag config based on color.diff, not color.interactive.

Make the print command trigger the pager when invoked using a capital 'P', to make it easier for the user to review long hunks. Note that if the PAGER ends unexpectedly before we've been able to send the payload, perhaps because the user is not interested in the whole thing, we might receive a SIGPIPE, which would abruptly and unexpectedly terminate the interactive session for the user. Therefore, we need to ignore a possible SIGPIPE signal. Add a test for this, in addition to the test for normal operation. For the SIGPIPE test, we need to make sure that we completely fill the operating system's buffer, otherwise we might not trigger the SIGPIPE signal. The normal size of this buffer in different OSs varies from a few KBs to 1MB. Use a payload large enough to guarantee that we exceed this limit.

2024-07-20add-patch: use normalize_marker() when recounting edited hunkPhillip Wood
After the user has edited a hunk the number of lines in the pre- and post- image lines is recounted the hunk header can be updated before passing the hunk to "git apply". The recounting code correctly handles empty context lines where the leading ' ' is omitted by treating '\n' and '\r' as context lines. Update this code to use normalize_marker() so that the handling of empty context lines is consistent with the rest of the hunk parsing code. There is a small change in behavior as normalize_marker() only treats "\r\n" as an empty context line rather than any line starting with '\r'. This should not matter in practice as Macs have used Unix line endings since MacOs 10 was released in 2001 and if it transpires that someone is still using an earlier version of MacOs where lines end with '\r' then we will need to change the handling of '\r' in normalize_marker() anyway.

2024-07-20add-patch: handle splitting hunks with diff.suppressBlankEmptyPhillip Wood
When "add -p" parses diffs, it looks for context lines starting with a single space. But when diff.suppressBlankEmpty is in effect, an empty context line will omit the space, giving us a true empty line. This confuses the parser, which is unable to split based on such a line. It's tempting to say that we should just make sure that we generate a diff without that option. However, although we do not parse hunks that the user has manually edited with parse_diff() we do allow the user to split such hunks. As POSIX calls the decision of whether to print the space here "implementation-defined" we need to handle edited hunks where empty context lines omit the space. So let's handle both cases: a context line either starts with a space or consists of a totally empty line by normalizing the first character to a space when we parse them. Normalizing the first character rather than changing the code to check for a space or newline will hopefully future proof against introducing similar bugs if the code is changed.

Varargs functions that are unannotated as printf-like or execl-like have been annotated as such. * jc/varargs-attributes: __attribute__: add a few missing format attributes __attribute__: mark some functions with LAST_ARG_MUST_BE_NULL __attribute__: remove redundant attribute declaration for git_die_config() __attribute__: trace2_region_enter_printf() is like "printf"
2024-06-14global: introduce `USE_THE_REPOSITORY_VARIABLE` macroPatrick Steinhardt
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.

The `empty_tree_oid_hex()` function use `the_repository` to derive the hash function that shall be used. Require callers to pass in the hash algorithm to get rid of this implicit dependency. While at it, remove the unused `empty_blob_oid_hex()` function. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2024-05-22add-patch: enforce only one-letter response to promptsJunio C Hamano
In a "git add -p" session, especially when we are not using the single-key mode, we may see 'qa' as a response to a prompt (1/2) Stage this hunk [y,n,q,a,d,j,J,g,/,e,p,?]? and then just do the 'q' thing (i.e. quit the session), ignoring everything other than the first byte. If 'q' and 'a' are next to each other on the user's keyboard, there is a plausible chance that we see 'qa' when the user who wanted to say 'a' fat-fingered and we ended up doing the 'q' thing instead. As we didn't think of a good reason during the review discussion why we want to accept excess letters only to ignore them, it appears to be a safe change to simply reject input that is longer than just one byte. The two exceptions are the 'g' command that takes a hunk number, and the '/' command that takes a regular expression. They have to be accompanied by their operands (this makes me wonder how users who set the interactive.singlekey configuration feed these operands---it turns out that we notice there is no operand and give them another chance to type the operand separately, without using single key input this time), so we accept a string that is more than one byte long. Keep the "use only the first byte, downcased" behaviour when we ask yes/no question, though. Neither on Qwerty or on Dvorak, 'y' and 'n' are not close to each other.

2024-05-08Merge branch 'rj/add-p-typo-reaction'Junio C Hamano
When the user responds to a prompt given by "git add -p" with an unsupported command, list of available commands were given, which was too much if the user knew what they wanted to type but merely made a typo. Now the user gets a much shorter error message. * rj/add-p-typo-reaction: add-patch: response to unknown command add-patch: do not show UI messages on stderr
2024-04-30add-patch: response to unknown commandRubén Justo
When the user gives an unknown command to the "add -p" prompt, the list of accepted commands with their explanation is given. This is the same output they get when they say '?'. However, the unknown command may be due to a user input error rather than the user not knowing the valid command. To reduce the likelihood of user confusion and error repetition, instead of displaying the list of accepted commands, display a short error message with the unknown command received, as feedback to the user. Include a reminder about the current command '?' in the new message, to guide the user if they want help.

There is no need to show some UI messages on stderr, and yet doing so may produce some undesirable results, such as messages appearing in an unexpected order.
