When a user checks out the upstream branch of HEAD, the upstream branch
not being a local branch, and then runs "git status", like this:
git clone $URL client
cd client
git checkout @{u}
git status
no status is printed, but instead an error message:
fatal: HEAD does not point to a branch
(This error message when running "git branch" persists even after
checking out other things - it only stops after checking out a branch.)
This is because "git status" reads the reflog when determining the "HEAD
detached" message, and thus attempts to DWIM "@{u}", but that doesn't
work because HEAD no longer points to a branch.
Therefore, when calculating the status of a worktree, tolerate dangling
marks. This is done by adding an additional parameter to
dwim_ref() and repo_dwim_ref().

In preparation for a future patch adding a boolean parameter to
repo_interpret_branch_name(), which might be easily confused with an
existing unsigned int parameter, refactor repo_interpret_branch_name()
to take an option struct instead of the unsigned int parameter.
The static function interpret_branch_mark() is also updated to take the
option struct in preparation for that future patch, since it will also
make use of the to-be-introduced boolean parameter.

887952b8c6 ("fetch: optionally allow disabling FETCH_HEAD update",
2020-08-18) introduced the ability to disable writing to FETCH_HEAD
during fetch, but did not suppress the "<source> -> FETCH_HEAD" message
when this ability is used. This message is misleading in this case,
because FETCH_HEAD is not written. Also, because "fetch" is used to
lazy-fetch missing objects in a partial clone, this significantly
clutters up the output in that case since the objects to be fetched are
potentially numerous.
Therefore, suppress this message when --no-write-fetch-head is passed
(but not when --dry-run is set).

In the common case where users have _not_ pushed a `ci-config` branch to
configure which branches should be included in the GitHub workflow runs,
there is a big fat ugly annotation about a failure in the run's log:
X Check failure on line 1 in .github
@github-actions github-actions / ci-config
.github#L1
Process completed with exit code 128.
The reason is that the `ci-config` job tries to clone that `ci-config`
branch, and even if it is configured to continue on error, the
annotation is displayed, and it is distracting.
Let's just handle this on the shell script level, so that the job's step
is not marked as a failure.

The section added in e76eec35540f (ci: allow per-branch config for
GitHub Actions, 2020-05-07) contains a `&&`-chain that connects several
commands. The first command is actually so long that it stretches over
multiple lines, and as per usual, the continuation lines are indented one
more level than the first.
However, the subsequent commands in the `&&`-chain were also indented
one more level than the first command, which was almost certainly
unintended.

This patch fixes a bug where xrealloc(ptr, 0) can double-free and
corrupt the heap on some platforms (including at least glibc).
The C99 standard says of malloc (section 7.20.3):
If the size of the space requested is zero, the behavior is
implementation-defined: either a null pointer is returned, or the
behavior is as if the size were some nonzero value, except that the
returned pointer shall not be used to access an object.
So we might get NULL back, or we might get an actual pointer (but we're
not allowed to look at its contents). To simplify our code, our
xmalloc() handles a NULL return by converting it into a single-byte
allocation. That way callers get consistent behavior. This was done way
back in 4e7a2eccc2 (?alloc: do not return NULL when asked for zero
bytes, 2005-12-29).
We also gave xcalloc() and xrealloc() the same treatment. And according
to C99, that is fine; the text above is in a paragraph that applies to
all three. But what happens to the memory we passed to realloc() in such
a case? I.e., if we do:
ret = realloc(ptr, 0);
and "ptr" is non-NULL, but we get NULL back, is "ptr" still valid? C99
doesn't cover this case specifically, but says (section 7.20.3.4):
The realloc function deallocates the old object pointed to by ptr and
returns a pointer to a new object that has the size specified by size.
So "ptr" is now deallocated, and we must only look at "ret". And since
"ret" is NULL, that means we have no allocated object at all. But that's
not quite the whole story. It also says:
If memory for the new object cannot be allocated, the old object is
not deallocated and its value is unchanged.
[...]
The realloc function returns a pointer to the new object (which may
have the same value as a pointer to the old object), or a null pointer
if the new object could not be allocated.
So if we see a NULL return with a non-zero size, we can expect that the
original object _is_ still valid. But with a non-zero size, it's
ambiguous. The NULL return might mean a failure (in which case the
object is valid), or it might mean that we successfully allocated
nothing, and used NULL to represent that.
The glibc manpage for realloc() explicitly says:
[...]if size is equal to zero, and ptr is not NULL, then the call is
equivalent to free(ptr).
Likewise, this StackOverflow answer:
https://stackoverflow.com/a/2135302
claims that C89 gave similar guidance (but I don't have a copy to verify
it). A comment on this answer:
https://stackoverflow.com/a/2022410
claims that Microsoft's CRT behaves the same.
But our current "retry with 1 byte" code passes the original pointer
again. So on glibc, we effectively free() the pointer and then try to
realloc() it again, which is undefined behavior.
The simplest fix here is to just pass "ret" (which we know to be NULL)
to the follow-up realloc(). But that means that a system which _doesn't_
free the original pointer would leak it. It's not clear if any such
systems exist, and that interpretation of the standard seems unlikely
(I'd expect a system that doesn't deallocate to simply return the
original pointer in this case). But it's easy enough to err on the safe
side, and just never pass a zero size to realloc() at all.

In fde97d8ac6 (Update documentation to remove incorrect GIT_DIFF_OPTS
example., 2006-11-27), the description of the 'GIT_EXTERNAL_DIFF'
variable was moved from 'diff-format.txt' to 'git.txt', and the
documentation was updated to remove a 'diff(1)' invocation since Git did
not use an external diff program anymore by default.
However, the description of 'GIT_EXTERNAL_DIFF' still mentions "instead
of the diff invocation described above", which is confusing.
Correct that outdated sentence.
Also, link to git(1) in 'diff-generate-patch.txt' when GIT_DIFF_OPTS and
GIT_EXTERNAL_DIFF are mentioned, so that users can easily know what
these variables are about.

The intention of `git init --separate-work-dir=<path>` is to move the
.git/ directory to a location outside of the main worktree. When used
within a linked worktree, however, rather than moving the .git/
directory as intended, it instead incorrectly moves the worktree's
.git/worktrees/<id> directory to <path>, thus disconnecting the linked
worktree from its parent repository and breaking the worktree in the
process since its local .git file no longer points at a location at
which it can find the object database. Fix this broken behavior.
An intentional side-effect of this change is that it also closes a
loophole not caught by ccf236a23a (init: disallow --separate-git-dir
with bare repository, 2020-08-09) in which the check to prevent
--separate-git-dir being used in conjunction with a bare repository was
unable to detect the invalid combination when invoked from within a
linked worktree. Therefore, add a test to verify that this loophole is
closed, as well.

A linked worktree's .git file is a "gitfile" pointing at the
.git/worktrees/<id> directory within the repository. When `git init
--separate-git-dir=<path>` is used on an existing repository to relocate
the repository's .git/ directory to a different location, it neglects to
update the .git files of linked worktrees, thus breaking the worktrees
by making it impossible for them to locate the repository. Fix this by
teaching --separate-git-dir to repair the .git file of each linked
worktree to point at the new repository location.

The .git/worktrees/<id>/gitdir file points at the location of a linked
worktree's .git file. Its content must be of the form
/path/to/worktree/.git (from which the location of the worktree itself
can be derived by stripping the "/.git" suffix). If the gitdir file is
deleted or becomes corrupted or outdated, then Git will be unable to
find the linked worktree. An easy way for the gitdir file to become
outdated is for the user to move the worktree manually (without using
"git worktree move"). Although it is possible to manually update the
gitdir file to reflect the new linked worktree location, doing so
requires a level of knowledge about worktree internals beyond what a
user should be expected to know offhand.
Therefore, teach "git worktree repair" how to repair broken or outdated
.git/worktrees/<id>/gitdir files automatically. (For this to work, the
command must either be invoked from within the worktree whose gitdir
file requires repair, or from within the main or any linked worktree by
providing the path of the broken worktree as an argument to "git
worktree repair".)

The .git file in a linked worktree is a "gitfile" which points back to
the .git/worktrees/<id> entry in the main worktree or bare repository.
If a worktree's .git file is deleted or becomes corrupted or outdated,
then the linked worktree won't know how to find the repository or any of
its own administrative files (such as 'index', 'HEAD', etc.). An easy
way for the .git file to become outdated is for the user to move the

within a worktree which has not become disconnected from the repository
-- such as one which was created after the repository was moved.)

When a repository has an alternate object directory configured, callers
can traverse through each alternate's MIDX by walking the '->next'
pointer.
But, when 'prepare_multi_pack_index_one()' loads multiple MIDXs, it
places the new ones at the front of this pointer chain, not at the end.
This can be confusing for callers such as 'git repack -ad', causing test
failures like in t7700.6 with 'GIT_TEST_MULTI_PACK_INDEX=1'.
The occurs when dropping a pack known to the local MIDX with alternates
configured that have their own MIDX. Since the alternate's MIDX is
returned via 'get_multi_pack_index()', 'midx_contains_pack()' returns
true (which is correct, since it traverses through the '->next' pointer
to find the MIDX in the chain that does contain the requested object).
But, we call 'clear_midx_file()' on 'the_repository', which drops the
MIDX at the path of the first MIDX in the chain, which (in the case of
t7700.6 is the one in the alternate).
This patch addresses that by:
- placing the local MIDX first in the chain when calling
'prepare_multi_pack_index_one()', and
- introducing a new 'get_local_multi_pack_index()', which explicitly
returns the repository-local MIDX, if any.
Don't impose an additional order on the MIDX's '->next' pointer beyond
that the first item in the chain must be local if one exists so that we
avoid a quadratic insertion.
Likewise, use 'get_local_multi_pack_index()' in
'remove_redundant_pack()' to fix the formerly broken t7700.6 when run
with 'GIT_TEST_MULTI_PACK_INDEX=1'.
Finally, note that the MIDX ordering invariant is only preserved by the
insertion order in 'prepare_packed_git()', which traverses through the
ODB's '->next' pointer, meaning we visit the local object store first.
This fragility makes this an undesirable long-term solution if more
callers are added, but it is acceptable for now since this is the only
caller.

However, the exit status of the hook is used as the exit status of
the 'checkout' command and is observable by anybody who spawned the

The FETCH_HEAD is now always read from the filesystem regardless of
the ref backend in use, as its format is much richer than the
normal refs, and written directly by "git fetch" as a plain file..
* hn/refs-fetch-head-is-special:
refs: read FETCH_HEAD and MERGE_HEAD generically
refs: move gitdir into base ref_store
refs: fix comment about submodule ref_stores
refs: split off reading loose ref data in separate function
