We were using the util pointer, which is a pointer to void, as an
unsigned char pointer. The pointer actually points to a struct
origin_data, which has a struct object_id as its first member, which in
turn has an unsigned char array as its first member, so this was valid.
Since we want to convert this to struct object_id, simply change the
pointer we're using.

We have several callers like
if (active_cache_changed && write_locked_index(...))
handle_error();
rollback_lock_file(...);
where the final rollback is needed because "!active_cache_changed"
shortcuts the if-expression. There are also a few variants of this,
including some if-else constructs that make it more clear when the
explicit rollback is really needed.
Teach `write_locked_index()` to take a new flag SKIP_IF_UNCHANGED and
simplify the callers. Leave the most complicated of the callers (in
builtin/update-index.c) unchanged. Rewriting it to use this new flag
would end up duplicating logic.
We could have made the new flag behave the other way round
("FORCE_WRITE"), but that could break existing users behind their backs.
Let's take the more conservative approach. We can still migrate existing
callers to use our new flag. Later we might even be able to flip the
default, possibly without entirely ignoring the risk to in-flight or
out-of-tree topics.

Change the behavior of git-commit back to what it was back in
d4bb43ee27 ("Invoke "git gc --auto" from commit, merge, am and
rebase.", 2007-09-05) when it was git-commit.sh.
Shortly afterwards in f5bbc3225c ("Port git commit to C.", 2007-11-08)
when it was ported to C, the "git gc --auto" invocation went away.
Since that unintended regression, git gc --auto only ran for git-am,
git-merge, git-fetch, and git-receive-pack. It was possible to
write a script that would "git commit" a lot of data locally, and gc
would never run.
One such repository that was locally committing generated zone file
changes had grown to a size of ~60GB before a daily cronjob was added
to "git gc", bringing it down to less than 1GB. This will make such
cases work without intervention.
I think fixing such pathological cases where the repository will grow
forever is a worthwhile trade-off for spending a couple of
milliseconds calling "git gc --auto" (in the common cases where it
doesn't do anything).

grep_source_init typically does three strdup()s, and in the threaded
case, the call from add_work() happens while holding grep_mutex.
We can thus reduce the time we hold grep_mutex by moving the
grep_source_init() call out of add_work(), and simply have add_work()
copy the initialized structure to the available slot in the todo
array.
This also simplifies the prototype of add_work(), since it no longer
needs to duplicate all the parameters of grep_source_init(). In the
callers of add_work(), we get to reduce the amount of code duplicated in
the threaded and non-threaded cases slightly (avoiding repeating the
long "GREP_SOURCE_OID, pathbuf.buf, path, oid" argument list); a
subsequent cleanup patch will make that even more so.

The "--show-all" revision option shows UNINTERESTING
commits. Some of these commits may be unparsed when we try
to show them (since we may or may not need to walk their
parents to fulfill the request).
Commit 3131b71301 (Add "--show-all" revision walker flag for
debugging, 2008-02-09) resolved this by just skipping
pretty-printing for commits without their object contents
cached, saying:
Because we now end up listing commits we may not even have been parsed
at all "show_log" and "show_commit" need to protect against commits
that don't have a commit buffer entry.
That was the easy fix to avoid the pretty-printer segfaulting,
but:
1. It doesn't work for all formats. E.g., --oneline
prints the oid for each such commit but not a trailing
newline, leading to jumbled output.
2. It only affects some commits, depending on whether we
happened to parse them or not (so if they were at the
tip of an UNINTERESTING starting point, or if we
happened to traverse over them, you'd see more data).
3. It unncessarily ties the decision to show the verbose
header to whether the commit buffer was cached. That
makes it harder to change the logic around caching
(e.g., if we could traverse without actually loading
the full commit objects).
These days it's safe to feed such a commit to the
pretty-print code. Since be5c9fb904 (logmsg_reencode: lazily
load missing commit buffers, 2013-01-26), we'll load it on
demand in such a case. So let's just always show the verbose
headers.
This does change the behavior of plumbing, but:
a. The --show-all option was explicitly introduced as a
debugging aid, and was never documented (and has rarely
even been mentioned on the list by git devs).
b. Avoiding the commits was already not deterministic due
to (2) above. So the caller might have seen full
headers for these commits anyway, and would need to be
prepared for it.

Similar to de121ffe5 (tag: respect `pager.tag` in list-mode only,
2017-08-02), use the DELAY_PAGER_CONFIG-mechanism to only respect
`pager.config` when we are listing or "get"ing config.
We have several getters and some are guaranteed to give at most one line
of output. Paging all getters including those could be convenient from a
documentation point-of-view. The downside would be that a misconfigured
or not so modern pager might wait for user interaction before
terminating. Let's instead respect the config for precisely those
getters which may produce more than one line of output.
`--get-urlmatch` may or may not produce multiple lines of output,
depending on the exact usage. Let's not try to recognize the two modes,
but instead make `--get-urlmatch` always respect the config. Analyzing
the detailed usage might be trivial enough here, but could establish a
precedent that we will never be able to enforce throughout the codebase
and that will just open a can of worms.
This fixes the failing test added in the previous commit. Also adapt the
test for whether `git config foo.bar bar` and `git config --get foo.bar`
respects `pager.config`.

Long time ago at fab47d05 ("merge: force edit and no-ff mode when
merging a tag object", 2011-11-07), "git merge" was made to always
create a merge commit when merging a tag, even when the side branch
being merged is a descendant of the current branch.
This default is good for merges made by upstream maintainers to
integrate work signed by downstream contributors, but will leave
pointless no-ff merges when downstream contributors pull a newer
release tag to make their long-running topic branches catch up with
the upstream. When there is no local work left on the topic, such a
merge should simply fast-forward to the commit pointed at by the
release tag.
Update the default (again) for "git merge" that merges a tag object
to (1) --no-ff (i.e. create a merge commit even when side branch
fast forwards) if the tag being merged is not at its expected place
in refs/tags/ hierarchy and (2) --ff (i.e. allow fast-forward update
when able) otherwise.

Although "git worktree add" learned to run the 'post-checkout' hook in
ade546be47 (worktree: invoke post-checkout hook, 2017-12-07), it
neglected to change to the directory of the newly-created worktree
before running the hook. Instead, the hook runs within the directory
from which the "git worktree add" command itself was invoked, which
effectively neuters the hook since it knows nothing about the new
worktree directory.
Further, ade546be47 failed to sanitize the environment before running
the hook, which means that user-assigned values of GIT_DIR and
GIT_WORK_TREE could mislead the hook about the location of the new
worktree. In the case of "git worktree add" being run from a bare
repository, the GIT_DIR="." assigned by Git itself leaks into the hook's
environment and breaks Git commands; this is so even when the working
directory is correctly changed to the new worktree before the hook runs
since ".", relative to the new worktree directory, does not point at the
bare repository.
Fix these problems by (1) changing to the new worktree's directory
before running the hook, and (2) sanitizing the environment of GIT_DIR
and GIT_WORK_TREE so hooks can't be confused by misleading values.
Enhance the t2025 'post-checkout' tests to verify that the hook is
indeed run within the correct directory and that Git commands invoked by
the hook compute Git-dir and top-level worktree locations correctly.
While at it, also add two new tests: (1) verify that the hook is run
within the correct directory even when the new worktree is created from
a sibling worktree (as opposed to the main worktree); (2) verify that
the hook is provided with correct context when the new worktree is
created from a bare repository (test provided by Lars Schneider).
Implementation Notes:
Rather than sanitizing the environment of GIT_DIR and GIT_WORK_TREE, an
alternative would be to set them explicitly, as is already done for
other Git commands run internally by "git worktree add". This patch opts
instead to sanitize the environment in order to clearly document that
the worktree is fully functional by the time the hook is run, thus does
not require special environmental overrides.
The hook is run manually, rather than via run_hook_le(), since it needs
to change the working directory to that of the worktree, and
run_hook_le() does not provide such functionality. As this is a one-off
case, adding 'run_hook' overloads which allow the directory to be set
does not seem warranted at this time.

The new command `git rebase --show-current-patch` is useful for seeing
the commit related to the current rebase state. Some however may find
the "git show" command behind it too limiting. You may want to
increase context lines, do a diff that ignores whitespaces...
For these advanced use cases, the user can execute any command they
want with the new pseudo ref REBASE_HEAD.
This also helps show where the stopped commit is from, which is hard
to see from the previous patch which implements --show-current-patch.

less .git/rebase-*/patch
which could turn out to be a lot longer to type if you are in a

"git worktree remove" basically consists of two things
- delete $GIT_WORK_TREE
- delete $GIT_DIR (which is $SUPER_GIT_DIR/worktrees/something)
If $GIT_WORK_TREE is already gone for some reason, we should be able
to finish the job by deleting $GIT_DIR.
Two notes:
- $GIT_WORK_TREE _can_ be missing if the worktree is locked. In that
case we must not delete $GIT_DIR because the real $GIT_WORK_TREE may
be in a usb stick somewhere. This is already handled because we
check for lock first.
- validate_worktree() is still called because it may do more checks in
future (and it already does something else, like checking main
worktree, but that's irrelevant in this case)

This command allows to delete a worktree. Like 'move' you cannot
remove the main worktree, or one with submodules inside [1].
For deleting $GIT_WORK_TREE, Untracked files or any staged entries are
considered precious and therefore prevent removal by default. Ignored
files are not precious.
When it comes to deleting $GIT_DIR, there's no "clean" check because
there should not be any valuable data in there, except:
- HEAD reflog. There is nothing we can do about this until somebody
steps up and implements the ref graveyard.
- Detached HEAD. Technically it can still be recovered. Although it
may be nice to warn about orphan commits like 'git checkout' does.
[1] We do 'git status' with --ignore-submodules=all for safety
anyway. But this needs a closer look by submodule people before we
can allow deletion. For example, if a submodule is totally clean,
but its repo not absorbed to the main .git dir, then deleting
worktree also deletes the valuable .submodule repo too.

This command allows to relocate linked worktrees. Main worktree cannot
(yet) be moved.
There are two options to move the main worktree, but both have
complications, so it's not implemented yet. Anyway the options are:
- convert the main worktree to a linked one and move it away, leave
the git repository where it is. The repo essentially becomes bare
after this move.
- move the repository with the main worktree. The tricky part is make
sure all file descriptors to the repository are closed, or it may
fail on Windows.

In check_ignore(), the first pathspec item determines the dtype for any
subsequent ones. That means that a pathspec matching a regular file can
prevent following pathspecs from matching directories, which makes no
sense. Fix that by determining the dtype for each pathspec separately,

Prior to 644eb60bd0 (builtin/describe.c: describe a blob,
2017-11-15), we noticed and complained about missing
objects, since they were not valid commits:
$ git describe 0000000000000000000000000000000000000000
fatal: 0000000000000000000000000000000000000000 is not a valid 'commit' object
After that commit, we feed any non-commit to lookup_blob(),
and complain only if it returns NULL. But the lookup_*
functions do not actually look at the on-disk object
database at all. They return an entry from the in-memory
object hash if present (and if it matches the requested
type), and otherwise auto-create a "struct object" of the
requested type.
A missing object would hit that latter case: we create a
bogus blob struct, walk all of history looking for it, and
then exit successfully having produced no output.
One reason nobody may have noticed this is that some related
cases do still work OK:
1. If we ask for a tree by sha1, then the call to
lookup_commit_referecne_gently() would have parsed it,
and we would have its true type in the in-memory object
hash.
2. If we ask for a name that doesn't exist but isn't a
40-hex sha1, then get_oid() would complain before we
even look at the objects at all.
We can fix this by replacing the lookup_blob() call with a
check of the true type via sha1_object_info(). This is not
quite as efficient as we could possibly make this check. We
know in most cases that the object was already parsed in the
earlier commit lookup, so we could call lookup_object(),
which does auto-create, and check the resulting struct's
type (or NULL). However it's not worth the fragility nor
code complexity to save a single object lookup.
The new tests cover this case, as well as that of a
tree-by-sha1 (which does work as described above, but was
not explicitly tested).

Make the new --prune-tags option work properly when git-fetch is
invoked with a <url> parameter instead of a <remote name>
parameter.
This change is split off from the introduction of --prune-tags due to
the relative complexity of munging the incoming argv, which is easier
to review as a separate change.

Add a --prune-tags option to git-fetch, along with fetch.pruneTags
config option and a -P shorthand (-p is --prune). This allows for
doing any of:
git fetch -p -P
git fetch --prune --prune-tags
git fetch -p -P origin
git fetch --prune --prune-tags origin
Or simply:
git config fetch.prune true &&
git config fetch.pruneTags true &&
git fetch
Instead of the much more verbose:
git fetch --prune origin 'refs/tags/*:refs/tags/*' '+refs/heads/*:refs/remotes/origin/*'
Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches *and* tags deleted
regularly, and have our local references to reflect upstream.
At work we create deployment tags in the repo for each rollout, and
there's *lots* of those, so they're archived within weeks for
performance reasons.
Without this change it's hard to centrally configure such repos in
/etc/gitconfig (on servers that are only used for working with
them). You need to set fetch.prune=true globally, and then for each
repo:
git -C {} config --replace-all remote.origin.fetch "refs/tags/*:refs/tags/*" "^\+*refs/tags/\*:refs/tags/\*$"
Now I can simply set fetch.pruneTags=true in /etc/gitconfig as well,
and users running "git pull" will automatically get the pruning
semantics I want.
Even though "git remote" has corresponding "prune" and "update
--prune" subcommands I'm intentionally not adding a corresponding
prune-tags or "update --prune --prune-tags" mode to that command.
It's advertised (as noted in my recent "git remote doc: correct
dangerous lies about what prune does") as only modifying remote
tracking references, whereas any --prune-tags option is always going
to modify what from the user's perspective is a local copy of the tag,
since there's no such thing as a remote tracking tag.
Ideally add_prune_tags_to_fetch_refspec() would be something that
would use ALLOC_GROW() to grow the 'fetch` member of the 'remote'
struct. Instead I'm realloc-ing remote->fetch and adding the
tag_refspec to the end.
The reason is that parse_{fetch,push}_refspec which allocate the
refspec (ultimately remote->fetch) struct are called many places that
don't have access to a 'remote' struct. It would be hard to change all
their callsites to be amenable to carry around the bookkeeping
variables required for dynamic allocation.
All the other callers of the API first incrementally construct the
string version of the refspec in remote->fetch_refspec via
add_fetch_refspec(), before finally calling parse_fetch_refspec() via
some variation of remote_get().
It's less of a pain to deal with the one special case that needs to
modify already constructed refspecs than to chase down and change all
the other callsites. The API I'm adding is intentionally not
generalized because if we add more of these we'd probably want to
re-visit how this is done.

fetch config" (87po6ahx87.fsf@evledraar.gmail.com;

Access the "remote" variable passed to the fetch_one() directly rather
than through the gtransport wrapper struct constructed in this
function for other purposes.
This makes the code more readable, as it's now obvious that the remote
struct doesn't somehow get munged by the prepare_transport() function
above, which takes the "remote" struct as an argument and constructs
the "gtransport" struct, containing among other things the "remote"
struct.
A subsequent change will copy this pattern to access a new
remote->prune_tags field, but without the use of the gtransport
variable. It's useful once that change lands to see that the two
pieces of code behave exactly the same.
This pattern of accessing the container struct was added in
737c5a9cde ("fetch: make --prune configurable", 2013-07-13) when this

Stop redundantly NULL-ing the last element of the refs structure,

This code dates back to b888d61c83 ("Make fetch a builtin",

The motivation for this change was to make a subsequent change which
would also modify the refs variable smaller, since it won't have to
copy this redundant "NULL the last + 1 item" pattern.
We may not end up keeping that change, but as this pattern is still

The command line parser of "git blame" is prepared to take an
ancient odd argument order "blame <path> <rev>" in addition to the
usual "blame [<rev>] <path>". It has at least two negative
ramifications:
- In order to tell these two apart, it checks if the last command
line argument names a path in the working tree, using
file_exists(). However, "blame <rev> <path>" is a request to
explain each and every line in the contents of <path> stored in
revision <rev> and does not need to have a working tree version
of the file. A check with file_exists() is simply wrong.
- To coerce that mistaken file_exists() check to work, the code
calls setup_work_tree() before doing so, because the path it has
is relative to the top-level of the project tree. However,
"blame <rev> <path>" MUST be usable even in a bare repository,
and there is no reason for letting setup_work_tree() complain
and die with "This operation must be run in a work tree".
To correct the former, switch to check if the last token is a
revision (and if so, parse arguments using "blame <path> <rev>"
rule). Correct the latter by getting rid of setup_work_tree() and
file_exists() check--the only case the call to this function matters
is when we are running "blame <path>" (i.e. no starting revision and
asking to blame the working tree file at <path>, digging through the
HEAD revision), but there is a call in setup_scoreboard() just
before it calls fake_working_tree_commit().

reset --hard currently uses its own logic for printing the first line of
the commit message in its output. Instead of just using the first line,
use the pretty machinery to create the output.
In addition to the easier to follow code, this makes the output more
consistent with other commands that print the title of the commit, such
as 'git commit --oneline' or 'git checkout', which both use
'pp_commit_easy()' with the CMIT_FMT_ONELINE modifier.
It is a slight change of the output if the second line of the commit
message is not a blank line, i.e. if the commit message is
foo
bar
previously we would print "HEAD is now at 000000 foo", while after
this change we print "HEAD is now at 000000 foo bar", same as 'git log
--oneline' shows "000000 foo bar".
So this does make the output more consistent with other commands, and
'reset' is a porcelain command, so nobody should be parsing the output
in scripts.
The current behaviour dates back to 0e5a7faa3a ("Make "git reset" a
builtin.", 2007-09-11), so I assume (without digging into the old
codebase too much) that the logic was implemented because there was
no convenience function such as 'pp_commit_easy' that would do this
already.

not a useful abstraction anymore.

Port the submodule subcommand 'sync' from shell to C using the same
mechanism as that used for porting submodule subcommand 'status'.
Hence, here the function cmd_sync() is ported from shell to C.
This is done by introducing four functions: module_sync(),
sync_submodule(), sync_submodule_cb() and print_default_remote().
The function print_default_remote() is introduced for getting
the default remote as stdout.

Currently the check whether to perform pickaxing is done via checking
`diffopt->pickaxe`, which contains the command line argument that we
want to pickaxe for. Soon we'll introduce a new type of pickaxing, that
will not store anything in the `.pickaxe` field, so let's migrate the
check to be dependent on pickaxe_opts.
It is not enough to just replace the check for pickaxe by pickaxe_opts,
because flags might be set, but pickaxing was not requested ('-i').
To cope with that, introduce a mask to check only for the bits indicating
the modes of operation.

Once upon a time, git-clone would refuse to write into a
directory that it did not itself create. The cleanup
routines for a failed clone could therefore just remove the
git and worktree dirs completely.
In 55892d2398 (Allow cloning to an existing empty directory,
2009-01-11), we learned to write into an existing directory.
Which means that doing:
mkdir foo
git clone will-fail foo
ends up deleting foo. This isn't a huge catastrophe, since
by definition foo must be empty. But it's somewhat
confusing; we should leave the filesystem as we found it.
Because we know that the only directory we'll write into is
an empty one, we can handle this case by just passing the
KEEP_TOPLEVEL flag to our recursive delete (if we could
write into populated directories, we'd have to keep track of
what we wrote and what we did not, which would be much
harder).
Note that we need to handle the work-tree and git-dir
separately, though, as only one might exist (and the new
tests in t5600 cover all cases).

Two parts of git-clone's setup logic check whether a
directory exists, and they both call stat directly with the
same scratch "struct stat" buffer. Let's pull that into a
helper, which has a few advantages:
- it makes the purpose of the stat calls more obvious
- it makes it clear that we don't care about the
information in "buf" remaining valid
- if we later decide to make the check more robust (e.g.,
complaining about non-directories), we can do it in one
place
Note that we could just use file_exists() for this, which
has identical code. But we specifically care about
directories, so this future-proofs us against that function
later getting more picky about seeing actual files.

The leak_pending flag is so awkward to use that multiple comments had to
be added around each occurrence. We only use it for remembering the
commits whose marks we have to clear after checking if the old HEAD is
detached. This is easy, though: We need to do that for the old commit,
the new one -- and for all refs.
Don't bother tracking exactly which commits need their flags cleared,
just nuke all we have in-core. This change is safe because refs can
point at anything, so other program parts can't depend on any kept flags
anyway. And since all refs are loaded we have to basically deal with
all commits anyway, so performance should not be negatively impacted.
