Ævar Arnfjörð Bjarmason	4998e93fa6	range-diff: plug memory leak in common invocation Create a public release_patch() version of the private free_patch() function added in `13b5af22f3` (apply: move libified code from builtin/apply.c to apply.{c,h}, 2016-04-22). Unlike the existing function this one doesn't free() the "struct patch" itself, so we can use it for variables on the stack. Use it in range-diff.c to fix a memory leak in common range-diff invocations, e.g.: git -P range-diff origin/master origin/next origin/seen Would emit several errors when compiled with SANITIZE=leak, but now runs cleanly.

René Scharfe	4e9a325253	apply: use strsets to track symlinks Symlink changes are tracked in a string_list, with the util pointer value indicating whether a symlink is kept or removed. Using fake pointer values requires awkward casts. Use one strset for each type of change instead to simplify and shorten the code.

Jerry Zhang	324eb77ee7	git-apply: add --allow-empty flag Some users or scripts will pipe "git diff" output to "git apply" when replaying diffs or commits. In these cases, they will rely on the return value of "git apply" to know whether the diff was applied successfully. However, for empty commits, "git apply" will fail. This complicates scripts since they have to either buffer the diff and check its length, or run diff again with "exit-code", essentially doing the diff twice. Add the "--allow-empty" flag to "git apply" which allows it to handle both empty diffs and empty commits created by "git format-patch --always" by doing nothing and returning 0. Add tests for both with and without --allow-empty. Signed-off-by: Jerry Zhang <jerry@skydio.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	3 years ago

Thomas Gummerer	ef283b3699	apply: make parse_git_diff_header public Make 'parse_git_header()' (renamed to 'parse_git_diff_header()') a "public" function in apply.h, so we can re-use it in range-diff in a subsequent commit. We're renaming the function to make it clearer in other parts of the codebase that we're talking about a diff header and not just any header.

Nguyễn Thái Ngọc Duy	82ea77eca7	apply.c: make init_apply_state() take a struct repository We're moving away from the_index in this code. "struct index_state *" could be added to struct apply_state. But let's aim long term and put struct repository here instead so that we could even avoid more global states in the future. The index will be available via apply_state->repo->index.

Martin Ågren	d13cd4c927	apply: remove `newfd` from `struct apply_state` Similar to a previous patch, we do not need to use `newfd` to signal that we have a lockfile to clean up. We can just unconditionally call `rollback_lock_file`. If we do not hold the lock, it will be a no-op. Where we check `newfd` to decide whether we need to take the lock, we can instead use `is_lock_file_locked()`.

Martin Ågren	6d058c8826	apply: move lockfile into `apply_state` We have two users of `struct apply_state` and the related functionality in apply.c. Each user sets up its `apply_state` by handing over a pointer to its static `lock_file`. (Before `076aa2cbd` (tempfile: auto-allocate tempfiles on heap, 2017-09-05), we could never free lockfiles, so making them static was a reasonable approach.) Other than that, they never directly access their `lock_file`s, which are instead handled by the functionality in apply.c. To make life easier for the caller and to make it less tempting for a future caller to mess with the lock, make apply.c fully responsible for setting up the `lock_file`. As mentioned above, it is now safe to free a `lock_file`, so we can make the `struct apply_state` contain an actual `struct lock_file` instead of a pointer to one. The user in builtin/apply.c is rather simple. For builtin/am.c, we might worry that the lock state is actually meant to be inherited across calls. But the lock is only taken as `apply_all_patches()` executes, and code inspection shows that it will always be released. Alternatively, we can observe that the lock itself is never queried directly. When we decide whether we should lock, we check a related variable `newfd`. That variable is not inherited, so from the point of view of apply.c, the state machine really is reset with each call to `init_apply_state()`. (It would be a bug if `newfd` and the lock status were not in sync. The duplication of information in `newfd` and the lock will be addressed in the next patch.)

René Scharfe	881529c846	apply: remove prefix_length member from apply_state Use a NULL-and-NUL check to see if we have a prefix and consistently use C string functions on it instead of storing its length in a member of struct apply_state.

Christian Couder	5b0b57fd91	apply: learn to use a different index file Sometimes we want to apply in a different index file.

Christian Couder	7e1bad24e3	apply: refactor `git apply` option parsing Parsing `git apply` options can be useful to other commands that want to call the libified apply functionality, because this way they can easily pass some options from their own command line to the libified apply functionality. This will be used by `git am` in a following patch. To make this possible, let's refactor the `git apply` option parsing code into a new libified apply_parse_options() function. Doing that makes it possible to remove some functions definitions from "apply.h" and make them static in "apply.c".

Christian Couder	45b78d8ba3	apply: change error_routine when silent To avoid printing anything when applying with `state->apply_verbosity == verbosity_silent`, let's save the existing warn and error routines before applying, and let's replace them with a routine that does nothing. Then after applying, let's restore the saved routines. Note that, as we need to restore the saved routines in all cases, we cannot return early any more in apply_all_patches().

Christian Couder	a46160d27e	apply: make it possible to silently apply This changes 'int apply_verbosely' into 'enum apply_verbosity', and changes the possible values of the variable from a bool to a tristate. The previous 'false' state is changed into 'verbosity_normal'. The previous 'true' state is changed into 'verbosity_verbose'. The new added state is 'verbosity_silent'. It should prevent anything to be printed on both stderr and stdout. This is needed because `git am` wants to first call apply functionality silently, if it can then fall back on 3-way merge in case of error. Printing on stdout, and calls to warning() or error() are not taken care of in this patch, as that will be done in following patches.
