The git worktree repair command failed to rewrite the .git file of
a working tree from a relative path to an absolute path when the
command was run in the working tree itself. The
read_gitfile_gently() function was modified to also return whether
the path originally recorded in the file was absolute, and this new
capability is used to correctly detect such mismatches.
* yn/worktree-repair-relative:
worktree repair: detect relative path in .git file correctly
The zsh completion script (in 'contrib/') has been updated to
correctly locate the Git command after global options like '-C' by
properly skipping them, similar to how the bash completion does.
* ll/zsh-complete-git-potty-options:
completion: zsh: support completion after "git -C <path>"
The application of the edited patch in 'git add -e' has been
refactored to use the internal apply API directly, avoiding the need
to spawn a 'git apply' subprocess.

builtin/add.c: replace run_command() with direct apply_all_patches() call
The pack-objects command has been updated to record the total bytes
written to pack files in trace2 output, allowing performance
analysis of different compression settings by comparing the
resulting pack sizes.

The mechanism to generate a packfile corresponding to the result of
a fetch/push has been made pluggable through a set of object
database callback functions, removing hardcoded references to
'pack-objects' and enabling alternative ODBs to serve packfiles
themselves.

The 'git receive-pack' command has been updated to use a new ODB
transaction interface for writing incoming packfiles, making it more
backend-agnostic.

The threshold for geometric repacking to trigger based on loose
object count has been adjusted to match that of 'git gc --auto',
preventing over-aggressive repacking during concurrent writes.
* ps/odb-geometric-repack-loose-threshold:
odb/files: be less aggressive with geometric repacking
The trailer parsing machinery has been updated to avoid mistaking
lines that begin with a URL (e.g., 'https://...') as trailer lines.
This prevents intended textual URLs from being mangled or mistakenly
treated as metadata keys.
* kh/trailers-no-urls:
trailers: stop recognizing URLs as trailers
The object database layer has been simplified by eagerly loading
alternate object directories upon initialization, instead of
deferring it to the first object lookup. This eliminates the need
for scattered lazy-loading calls throughout the codebase and paves
the way for integrating alternates with the pluggable backends.
* ps/odb-eagerly-load-alternates:
odb: drop `alternates_db` field
odb: drop `loaded_alternates` field
odb: eagerly initialize alternates
odb: decouple source path comparisons from `the_repository`

The command line completion (in contrib/) has been taught to handle
the experimental 'git history' command.
* vm/complete-history:
completion: complete 'git history split' pathspecs
completion: complete 'git history --update-refs' values
completion: complete 'git history --empty' values
completion: add 'git history' subcommands
The object database (odb) API has been refactored to distinguish
between missing objects and corrupt ones by returning more
descriptive error statuses. Both the packed and loose backends now
faithfully propagate error details using a generic strbuf error
mechanism, removing backend-specific leakage from central lookup
paths.
* ps/odb-generic-corrupt-objects:
odb: handle `OBJECT_INFO_DIE_IF_CORRUPT` generically
odb/source: allow `read_object_info()` to bubble up error messages
odb/source: let callers discern missing and corrupt objects
odb/source: introduce error status when reading objects
odb/source-packed: flag known-bad objects as corrupt and not missing
The DWIM logic in 'git worktree add' sometimes tried to infer a
remote-tracking branch when an explicit '-b' or '-B' option was
given to create a new branch, causing the explicit branch name to
be ignored, which has been corrected.
* yn/worktree-add-no-dwim-with-b:
worktree add: shouldn't dwim if -b or -B is given
The instructions for deprecated commands emitted by
you_still_use_that() have been reworded to clarify that the removal
decision is final and to provide more assertive guidance on finding
a replacement.
* jc/you-still-use-that:
you_still_use_that(): reword the instructions
'git worktree add' did not prevent DWIM behavior when '-b' or '-B' was
specified, which has been corrected.
* yn/worktree-ambiguous-remote-advice:
worktree add: treat multiple matches with --guess-remote as an error
worktree add: improve message for ambiguous remote branch name
checkout: improve message for ambiguous remote branch name
checkout: extract function to display advice for ambiguous remotes
The reftable code has been optimized to avoid an unnecessary
stat/reload of the stack when an addition already holds the
list_file lock, reducing the number of newfstatat syscalls from
linear to constant when writing refs.
* kn/reftable-optimize-reloading:
reftable/stack: avoid reloading the stack when already locked
reftable/stack: move list lock to `struct reftable_stack`

A heap-use-after-free bug in the object name parsing code when
reporting failures with a relative path to a sparse directory has
been corrected.
* sk/object-name-use-after-free:
object-name: avoid use-after-free in get_oid_with_context_1()
The documentation for 'git format-rev' has been updated to use the
[synopsis] block definition on code blocks to properly highlight
placeholders, and a quoting inconsistency in the running text has
been fixed.
* kh/format-rev-doc-synopsis:
doc: format-rev: use [synopsis] on code block
doc: format-rev: quote subject placeholder before and after
Given a state in which the cross-references between the worktree and
the repository (specifically worktree/id/gitdir in the main repository
and the .git file in the worktree) are recorded using absolute paths,
setting 'worktree.useRelativePaths=true' and running 'git worktree
repair' within the main worktree converts them to relative paths.
Conversely, given a state in which the cross-references are recorded
using relative paths, one would expect that setting
'worktree.useRelativePaths=false' and running 'git worktree repair'
would convert them to absolute paths. However, they remain as relative
paths.
This is because we incorrectly use read_gitfile_gently(), which always
returns an absolute path. To fix this, introduce read_gitfile_raw(),
which reads the path from the .git file without resolving it to an
absolute path.
Because read_gitfile_raw() does not validate the path with
is_git_directory(), repair_gitfile() performs this validation to
preserve the existing behavior.

there is recourse other than adopting the new workflow. Clarify
that the message is there merely to help them find a replacement

When 'git worktree add <path>' is invoked without <commit-ish> and
with the --guess-remote option (or when worktree.guessRemote is set to
true), it tries to find a remote-tracking branch matching the basename
of <path>.
Currently, the behavior when multiple matches are found is the same as
when no match is found: it falls back to creating a branch from
HEAD. This has been the behavior since 71d6682d8c (worktree: add
--guess-remote option to add subcommand, 2017-11-29), when the option
was first introduced.
However, if the specified <path> matches any remote-tracking branch,
we infer that the user intended to use one of the remote-tracking
branches as the start-point rather than HEAD. So we abort the creation
of the branch and worktree when there are multiple matches, and
instruct the user to choose the start-point.

When the user runs 'git worktree add ../foo-dir bar-topic' without
specifying a remote, and there is no local branch named bar-topic, we
try to guess which remote branch bar-topic refers to, then create a
new branch named bar-topic that tracks the remote branch.
If multiple remotes have a branch named bar-topic, we silently gave
up, leaving the variable 'branch' intact. We then entered the
conditional clause 'if (!opts.orphan &&
!lookup_commit_reference_by_name(branch))' and triggered an "invalid
reference" error. This error message did not provide enough
information to resolve the ambiguity.
When multiple matching branches are found, display a hint and a
descriptive error message and die immediately.

When the user runs 'git checkout bar-topic' without specifying a
remote, and there is no local branch named bar-topic, we try to guess
which remote branch bar-topic refers to, then create a new branch
named bar-topic that tracks the remote branch.
If multiple remotes have a branch named bar-topic, we cannot determine
a single remote.
To make it easier to resolve the ambiguity, provide the names of the
matching remotes for the specified branch name.
To achieve that, add an optional feature to the
`unique_tracking_name()` function that allows the matching remote
names to be exposed to the caller.
