Leon Michalak 2b3ae04011 add-patch: add diff.context command line overrides
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.

This mimics commands such as diff and log, which allow for both context
file configuration and command line overrides.

Patrick Steinhardt 9ce196e86b config: drop `git_config()` wrapper
In 036876a106 (config: hide functions using `the_repository` by
default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.

Follow through with that intent and remove `git_config()`. All callsites
are adjusted so that they use `repo_config(the_repository, ...)`
instead. While some callsites might already have a repository available,
this mechanical conversion is the exact same as the current situation
and thus cannot cause any regression. Those sites should eventually be
cleaned up in a later patch series.

brian m. carlson bc303718cc builtin/stash: provide a way to import stashes from a ref
Now that we have a way to export stashes to a ref, let's provide a way
to import them from such a ref back to the stash.  This works much the
way the export code does, except that we strip off the first parent
chain commit and then store each resulting commit back to the stash.

We don't clear the stash first and instead add the specified stashes to
the top of the stash.  This is because users may want to export just a
few stashes, such as to share a small amount of work in progress with a
colleague, and it would be undesirable for the receiving user to lose
all of their data.  For users who do want to replace the stash, it's
easy to do to: simply run "git stash clear" first.

We specifically rely on the fact that we'll produce identical stash
commits on both sides in our tests.  This provides a cheap,
straightforward check for our tests and also makes it easy for users to
see if they already have the same data in both repositories.

brian m. carlson 27c0be9a3f builtin/stash: provide a way to export stashes to a ref
A common user problem is how to sync in-progress work to another
machine.  Users currently must use some sort of transfer of the working
tree, which poses security risks and also necessarily causes the index
to become dirty.  The experience is suboptimal and frustrating for
users.

A reasonable idea is to use the stash for this purpose, but the stash is
stored in the reflog, not in a ref, and as such it cannot be pushed or
pulled.  This also means that it cannot be saved into a bundle or
preserved elsewhere, which is a problem when using throwaway development
environments.

In addition, users often want to replicate stashes across machines, such
as when they must use multiple machines or when they use throwaway dev
environments, such as those based on the Devcontainer spec, where they
might otherwise lose various in-progress work.

Let's solve this problem by allowing the user to export the stash to a
ref (or, to just write it into the repository and print the hash, à la
git commit-tree).  Introduce git stash export, which writes a chain of
commits where the first parent is always a chain to the previous stash,
or to a single, empty commit (for the final item) and the second is the
stash commit normally written to the reflog.

Iterate over each stash from top to bottom, looking up the data for each
one, and then create the chain from the single empty commit back up in
reverse order.  Generate a predictable empty commit so our behavior is
reproducible.  Create a useful commit message, preserving the author and
committer information, to help users identify stash commits when viewing
them as normal commits.

If the user has specified specific stashes they'd like to export
instead, use those instead of iterating over all of the stashes.

As part of this, specifically request quiet behavior when looking up the
OID for a revision because we will eventually hit a revision that
doesn't exist and we don't want to die when that occurs.

When exporting stashes, be sure to verify that they look like valid
stashes and don't contain invalid data.  This will help avoid failures
on import or problems due to attempting to export invalid refs that are
not stashes.

K Jayatheerth ffb36c64f2 stash: fix incorrect branch name in stash message
When creating a stash, Git uses the current branch name
of the superproject to construct the stash commit message.
However, in repositories with submodules,
the message may mistakenly display the submodule branch name instead.

This is because `refs_resolve_ref_unsafe()` returns a pointer to a static buffer.
Subsequent calls to the same function overwrite the buffer,
corrupting the originally fetched `branch_name` used for the stash message.

Use `xstrdup()` to duplicate the branch name immediately after resolving it,
so that later buffer overwrites do not affect the stash message.

Phillip Wood 468817bab2 stash: allow "git stash [<options>] --patch <pathspec>" to assume push
The support for assuming "push" when "-p" is given introduced in
9e140909f6 (stash: allow pathspecs in the no verb form, 2017-02-28) is
very narrow, neither "git stash -m <message> -p <pathspec>" nor "git
stash --patch <pathspec>" imply "push" and die instead. Relax this by
passing PARSE_OPT_STOP_AT_NON_OPTION when push is being assumed and then
setting "force_assume" if "--patch" was present. This means "git stash
<pathspec> -p" still dies so that it does not assume the user meant
"push" if they mistype a subcommand name but "git stash -m <message> -p
<pathspec>" will now succeed. The test added in the last commit is
adjusted to check that push is still assumed when "--patch" comes after
other options on the command-line.

Phillip Wood e6659b77df stash: allow "git stash -p <pathspec>" to assume push again
Historically "git stash [<options>]" was assumed to mean "git stash save
[<options>]". Since 1ada5020b3 (stash: use stash_push for no verb form,
2017-02-28) it is assumed to mean "git stash push [<options>]". As the
push subcommand supports pathspecs, 9e140909f6 (stash: allow pathspecs
in the no verb form, 2017-02-28) allowed "git stash -p <pathspec>" to
mean "git stash push -p <pathspec>". This was broken in 8c3713cede
(stash: eliminate crude option parsing, 2020-02-17) which failed to
account for "push" being added to the start of argv in cmd_stash()
before it calls push_stash() and kept looking in argv[0] for "-p" after
moving the code to push_stash().

Fix this by regression by checking argv[1] instead of argv[0] and add a
couple of tests to prevent future regressions.

In 9b1cb5070f (builtin: add a repository parameter for builtin
functions, 2024-09-13) the repository was passed down to all builtin

without depending on the global `the_repository` variable.

other subsystems and cleanup usage of global variables like
'the_repository' and 'the_hash_algo'.

Jeff King 1a60f2066a drop trailing newline from warning/error/die messages
Our error reporting routines append a trailing newline, and the strings
we pass to them should not include them (otherwise we get an extra blank
line after the message).

These cases were all found by looking at the results of:

  git grep -P '[^_](error|error_errno|warning|die|die_errno)\(.*\\n"[,)]' '*.c'

Note that we _do_ sometimes include a newline in the middle of such
messages, to create multiline output (hence our grep matching "," or ")"
after we see the newline, so we know we're at the end of the string).

It's possible that one or more of these cases could intentionally be
including a blank line at the end, but having looked at them all
manually, I think these are all just mistakes.

    $ git stash push --keep-index --include-untracked
    error: pathspec ':/' did not match any file(s) known to git

This error comes from `git checkout --no-overlay $i_tree -- :/`, which
we execute to reset the working tree to the state in our index. As the
tree generated from the index is empty in our case, ':/' does not match
any files and thus causes git-checkout(1) to error out.

Fix the issue by skipping the checkout when the index tree is empty. As
explained in the in-code comment, this should be the correct thing to do
as there is nothing that we'd have to reset in the first place.

Junio C Hamano 4460e052e0 remerge-diff: clean up temporary objdir at a central place
After running a diff between two things, or a series of diffs while
walking the history, the diff computation is concluded by a call to
diff_result_code() to extract the exit status of the diff machinery.

The function can work on "struct diffopt", but all the callers
historically and currently pass "struct diffopt" that is embedded in
the "struct rev_info" that is used to hold the remerge_diff bit and
the remerge_objdir variable that points at the temporary object
directory in use.

Redefine diff_result_code() to take the whole "struct rev_info" to
give it an access to these members related to remerge-diff, so that
it can get rid of the temporary object directory for any and all
callers that used the feature.  We can lose the equivalent code to
do so from the code paths for individual commands, diff-tree, diff,
and log.

Antonin Delpeuch 9c93ba4d0a merge-recursive: honor diff.algorithm
The documentation claims that "recursive defaults to the diff.algorithm
config setting", but this is currently not the case. This fixes it,
ensuring that diff.algorithm is used when -Xdiff-algorithm is not
supplied. This affects the following porcelain commands: "merge",
"rebase", "cherry-pick", "pull", "stash", "log", "am" and "checkout".
It also affects the "merge-tree" ancillary interrogator.

This change refactors the initialization of merge options to introduce
two functions, "init_merge_ui_options" and "init_merge_basic_options"
instead of just one "init_merge_options". This design follows the
approach used in diff.c, providing initialization methods for
porcelain and plumbing commands respectively. Thanks to that, the
"replay" and "merge-recursive" plumbing commands remain unaffected by
diff.algorithm.

Patrick Steinhardt 63c9bd372e commit: fix leaking parents when calling `commit_tree_extended()`
When creating commits via `commit_tree_extended()`, the caller passes in
a string list of parents. This call implicitly transfers ownership of
that list to the function, which is quite surprising to begin with. But
to make matters worse, `commit_tree_extended()` doesn't even bother to
free the list of parents in error cases. The result is a memory leak,
and one that the caller cannot fix by themselves because they do not
know whether parts of the string list have already been released.

Refactor the code such that callers can keep ownership of the list of
parents, which is getting indicated by parameter being a constant
pointer now. Free the lists at the calling site and add a common exit
path to those sites as required.

Adam Johnson 5fb7686409 stash: fix "--staged" with binary files
"git stash --staged" errors out when given binary files, after saving the
stash.

This behaviour dates back to the addition of the feature in 41a28eb6c1
(stash: implement '--staged' option for 'push' and 'save', 2021-10-18).
Adding the "--binary" option of "diff-tree" fixes this. The "diff-tree" call
in stash_patch() also omits "--binary", but that is fine since binary files
cannot be selected interactively.

Patrick Steinhardt d2058cb2f0 builtin/stash: report failure to write to index
The git-stash(1) command needs to write to the index for many of its
operations. When the index is locked by a concurrent writer it will thus
fail to operate, which is expected. What is not expected though is that
we do not print any error message at all in this case. The user can thus
easily miss the fact that the command didn't do what they expected it to
do and would be left wondering why that is.

Fix this bug and report failures to write to the index. Add tests for
the subcommands which hit the respective code paths.

While at it, unify error messages when writing to the index fails. The
chosen error message is already used in "builtin/stash.c".

Elijah Newren eea0e59ffb treewide: remove unnecessary includes in source files
Each of these were checked with
   gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE}
to ensure that removing the direct inclusion of the header actually
resulted in that header no longer being included at all (i.e. that
no other header pulled it in transitively).

...except for a few cases where we verified that although the header
was brought in transitively, nothing from it was directly used in
that source file.  These cases were:
  * builtin/credential-cache.c
  * builtin/pull.c
  * builtin/send-pack.c

Feeding "git stash store" with a random commit that was not created

  stash: be careful what we store
2023-10-23 13:56:37 -07:00
Junio C Hamano d9b6634589 stash: be careful what we store
"git stash store" is meant to store what "git stash create"
produces, as these two are implementation details of the end-user
facing "git stash save" command.  Even though it is clearly
documented as such, users would try silly things like "git stash
store HEAD" to render their stash unusable.

Worse yet, because "git stash drop" does not allow such a stash
entry to be removed, "git stash clear" would be the only way to
recover from such a mishap.  Reuse the logic that allows "drop" to
refrain from working on such a stash entry to teach "store" to avoid
storing an object that is not a stash entry in the first place.

Eric W. Biederman efed687edc tree-walk: init_tree_desc take an oid to get the hash algorithm
To make it possible for git ls-tree to display the tree encoded
in the hash algorithm of the oid specified to git ls-tree, update
init_tree_desc to take as a parameter the oid of the tree object.

Update all callers of init_tree_desc and init_tree_desc_gently
to pass the oid of the tree object.

Use the oid of the tree object to discover the hash algorithm
of the oid and store that hash algorithm in struct tree_desc.

Use the hash algorithm in decode_tree_entry and
update_tree_entry_internal to handle reading a tree object encoded in
a hash algorithm that differs from the repositories hash algorithm.
