When a user does not tell "git pull" to use rebase or merge, the
command gives a loud message telling a user to choose between
rebase or merge but creates a merge anyway, forcing users who would

no reason to stop or force the user to choose between rebase or
merge if the history fast-forwards.

On `git maintenance start`, we add a few entries to the user's cron
table. We wrap our entries using two magic markers, "# BEGIN GIT
MAINTENANCE SCHEDULE" and "# END GIT MAINTENANCE SCHEDULE". At a later
`git maintenance stop`, we will go through the table and remove these
lines. Or rather, we will remove the "BEGIN" marker, the "END" marker
and everything between them.
Alas, we have a bug in how we detect the "END" marker: we don't. As we
loop through all the lines of the crontab, if we are in the "old
region", i.e., the region we're aiming to remove, we make an early
`continue` and don't get as far as checking for the "END" marker. Thus,
once we've seen our "BEGIN", we remove everything until the end of the
file.
Rewrite the logic for identifying these markers. There are four cases
that are mutually exclusive: The current line starts a region or it ends
it, or it's firmly within the region, or it's outside of it (and should
be printed).

This fixes a segmentation fault.
The bug is caused by dereferencing `new_branch_info->commit` when it is
`NULL`, which is the case when the tree-ish argument is actually a tree,
not a commit-ish. This was introduced in 5602b500c3c (builtin/checkout:

that the special tree-ish `HEAD...` is handled correctly.

`git worktree repair` knows how to repair the two-way links between the
repository and a worktree as long as a link in one or the other
direction is sound. For instance, if a linked worktree is moved (without
using `git worktree move`), repair is possible because the worktree
still knows the location of the repository even though the repository no
longer knows where the worktree is. Similarly, if the repository is
moved, repair is possible since the repository still knows the locations
of the worktrees even though the worktrees no longer know where the
repository is.
However, if both the repository and the worktrees are moved, then links
are severed in both directions, and no repair is possible. This is the
case even when the new worktree locations are specified as arguments to
`git worktree repair`. The reason for this limitation is twofold. First,
when `repair` consults the worktree's gitfile (/path/to/worktree/.git)
to determine the corresponding <repo>/worktrees/<id>/gitdir file to fix,
<repo> is the old path to the repository, thus it is unable to fix the
`gitdir` file at its new location since it doesn't know where it is.
Second, when `repair` consults <repo>/worktrees/<id>/gitdir to find the
location of the worktree's gitfile (/path/to/worktree/.git), the path
recorded in `gitdir` is the old location of the worktree's gitfile, thus
it is unable to repair the gitfile since it doesn't know where it is.
Fix these shortcomings by teaching `repair` to attempt to infer the new
location of the <repo>/worktrees/<id>/gitdir file when the location
recorded in the worktree's gitfile has become stale but the file is
otherwise well-formed. The inference is intentionally simple-minded.
For each worktree path specified as an argument, `git worktree repair`
manually reads the ".git" gitfile at that location and, if it is
well-formed, extracts the <id>. It then searches for a corresponding
<id> in <repo>/worktrees/ and, if found, concludes that there is a
reasonable match and updates <repo>/worktrees/<id>/gitdir to point at
the specified worktree path. In order for <repo> to be known, `git
worktree repair` must be run in the main worktree or bare repository.
`git worktree repair` first attempts to repair each incoming
/path/to/worktree/.git gitfile to point at the repository, and then
attempts to repair outgoing <repo>/worktrees/<id>/gitdir files to point
at the worktrees. This sequence was chosen arbitrarily when originally
implemented since the order of fixes is immaterial as long as one side
of the two-way link between the repository and a worktree is sound.
However, for this new repair technique to work, the order must be
reversed. This is because the new inference mechanism, when it is
successful, allows the outgoing <repo>/worktrees/<id>/gitdir file to be
repaired, thus fixing one side of the two-way link. Once that side is
fixed, the other side can be fixed by the existing repair mechanism,
hence the order of repairs is now significant.
Two safeguards are employed to avoid hijacking a worktree from a
different repository if the user accidentally specifies a foreign
worktree as an argument. The first, as described above, is that it
requires an <id> match between the repository and the worktree. That
itself is not foolproof for preventing hijack, so the second safeguard
is that the inference will only kick in if the worktree's
/path/to/worktree/.git gitfile does not point at a repository.

Remove this unreachable code. It was found by SunCC, it's found by a
non-fatal warning emitted by SunCC. It's one of the things it's more
vehement about than GCC & Clang.
It complains about a lot of other similarly unreachable code, e.g. a
BUG(...) without a "return", and a "return 0" after a long if/else,
both of whom have "return" statements. Those are also genuine
redundancies to a compiler, but arguably make the code a bit easier to
read & less fragile to maintain.
These return/break cases are just unnecessary however, and as seen
here the surrounding code just did a plain "return" without a "break"
already.

Not all code paths want to show that advice, though. In particular, the

via the `INIT_DB_QUIET` flag.

git rev-parse has several options which print various paths. Some of
these paths are printed relative to the current working directory, and
some are absolute.
Normally, this is not a problem, but there are times when one wants
paths entirely in one format or another. This can be done trivially if
the paths are canonical, but canonicalizing paths is not possible on
some shell scripting environments which lack realpath(1) and also in Go,
which lacks functions that properly canonicalize paths on Windows.
To help out the scripter, let's provide an option which turns most of
the paths printed by git rev-parse to be either relative to the current
working directory or absolute and canonical. Document which options are
affected and which are not so that users are not confused.
This approach is cleaner and tidier than providing duplicates of
existing options which are either relative or absolute.
Note that if the user needs both forms, it is possible to pass an
additional option in the middle of the command line which changes the
behavior of subsequent operations.

The on-disk bitmap format has a flag to mark a bitmap to be "reused".
This is a rather curious feature, and works like this:
- a run of pack-objects would decide to mark the last 80% of the
bitmaps it generates with the reuse flag
- the next time we generate bitmaps, we'd see those reuse flags from
the last run, and mark those commits as special:
- we'd be more likely to select those commits to get bitmaps in
the new output
- when generating the bitmap for a selected commit, we'd reuse the
old bitmap as-is (rearranging the bits to match the new pack, of
course)
However, neither of these behaviors particularly makes sense.
Just because a commit happened to be bitmapped last time does not make
it a good candidate for having a bitmap this time. In particular, we may
choose bitmaps based on how recent they are in history, or whether a ref
tip points to them, and those things will change. We're better off
re-considering fresh which commits are good candidates.
Reusing the existing bitmap _is_ a reasonable thing to do to save
computation. But only reusing exact bitmaps is a weak form of this. If
we have an old bitmap for A and now want a new bitmap for its child, we
should be able to compute that only by looking at trees and that are new
to the child. But this code would consider only exact reuse (which is
perhaps why it was eager to select those commits in the first place).
Furthermore, the recent switch to the reverse-edge algorithm for
generating bitmaps dropped this optimization entirely (and yet still
performs better).
So let's do a few cleanups:
- drop the whole "reusing bitmaps" phase of generating bitmaps. It's
not helping anything, and is mostly unused code (or worse, code that
is using CPU but not doing anything useful)
- drop the use of the on-disk reuse flag to select commits to bitmap
- stop setting the on-disk reuse flag in bitmaps we generate (since
nothing respects it anymore)
We will keep a few innards of the reuse code, which will help us
implement a more capable version of the "reuse" optimization:
- simplify rebuild_existing_bitmaps() into a function that only builds
the mapping of bits between the old and new orders, but doesn't
actually convert any bitmaps
- make rebuild_bitmap() public; we'll call it lazily to convert bitmaps
as we traverse (using the mapping created above)

If 'git clone' couldn't execute 'transport_fetch_refs()' (e.g., because
of an error on the remote's side in 'git upload-pack'), then it will
silently ignore it.
Even though this has been the case at least since clone was ported to C
(way back in 8434c2f1af (Build in clone, 2008-04-27)), 'git fetch'
doesn't ignore these and reports any failures it sees.
That suggests that ignoring the return value in 'git clone' is simply an
oversight that should be corrected. That's exactly what this patch does.
(Noticing and fixing this is no coincidence, we'll want it in the next
patch in order to demonstrate a regression in 'git upload-pack' via a
'git clone'.)
There's no additional logging here, but that matches how 'git fetch'
handles the same case. An assumption there is that whichever part of
transport_fetch_refs() fails will complain loudly, so any additional
logging here is redundant.

sparse-checkouts are built on the patterns in the
$GIT_DIR/info/sparse-checkout file, where commands have modified
behavior for paths that do not match those patterns. The differences in
behavior, as far as the bugs concerned here, fall into three different
categories (with git subcommands that fall into each category listed):
* commands that only look at files matching the patterns:
* status
* diff
* clean
* update-index
* commands that remove files from the working tree that do not match
the patterns, and restore files that do match them:
* read-tree
* switch
* checkout
* reset (--hard)
* commands that omit writing files to the working tree that do not
match the patterns, unless those files are not clean:
* merge
* rebase
* cherry-pick
* revert
There are some caveats above, e.g. a plain `git diff` ignores files
outside the sparsity patterns but will show diffs for paths outside the
sparsity patterns when revision arguments are passed. (Technically,
diff is treating the sparse paths as matching HEAD.) So, there is some
internal inconsistency among these commands. There are also additional
commands that should behave differently in the face of sparse-checkouts,
as the sparse-checkout documentation alludes to, but the above is
sufficient for me to explain how `git stash` is affected.
What is relevant here is that logically 'stash' should behave like a
merge; it three-way merges the changes the user had in progress at stash
creation time, the HEAD at the time the stash was created, and the
current HEAD, in order to get the stashed changes applied to the current
branch. However, this simplistic view doesn't quite work in practice,
because stash tweaks it a bit due to two factors: (1) flags like
--keep-index and --include-untracked (why we used two different verbs,
'keep' and 'include', is a rant for another day) modify what should be
staged at the end and include more things that should be quasi-merged,
(2) stash generally wants changes to NOT be staged. It only provides
exceptions when (a) some of the changes had conflicts and thus we want
to use stages to denote the clean merges and higher order stages to
mark the conflicts, or (b) if there is a brand new file we don't want
it to become untracked.
stash has traditionally gotten this special behavior by first doing a
merge, and then when it's clean, applying a pipeline of commands to
modify the result. This series of commands for
unstaging-non-newly-added-files came from the following commands:
git diff-index --cached --name-only --diff-filter=A $CTREE >"$a"
git read-tree --reset $CTREE
git update-index --add --stdin <"$a"
rm -f "$a"
Looking back at the different types of special sparsity handling listed
at the beginning of this message, you may note that we have at least one
of each type covered here: merge, diff-index, and read-tree. The weird
mix-and-match led to 3 different bugs:
(1) If a path merged cleanly and it didn't match the sparsity patterns,
the merge backend would know to avoid writing it to the working tree and
keep the SKIP_WORKTREE bit, simply only updating it in the index.
Unfortunately, the subsequent commands would essentially undo the
changes in the index and thus simply toss the changes altogether since
there was nothing left in the working tree. This means the stash is
only partially applied.
(2) If a path existed in the worktree before `git stash apply` despite
having the SKIP_WORKTREE bit set, then the `git read-tree --reset` would
print an error message of the form
error: Entry 'modified' not uptodate. Cannot merge.
and cause stash to abort early.
(3) If there was a brand new file added by the stash, then the
diff-index command would save that pathname to the temporary file, the
read-tree --reset would remove it from the index, and the update-index
command would barf due to no such file being present in the working
copy; it would print a message of the form:
error: NEWFILE: does not exist and --remove not passed
fatal: Unable to process path NEWFILE
and then cause stash to abort early.
Basically, the whole idea of unstage-unless-brand-new requires special
care when you are dealing with a sparse-checkout. Fix these problems
by applying the following simple rule:
When we unstage files, if they have the SKIP_WORKTREE bit set,
clear that bit and write the file out to the working directory.
(*) If there's already a file present in the way, rename it first.
This fixes all three problems in t7012.13 and allows us to mark it as
passing.

When stash was converted from shell to a builtin, it merely
transliterated the forking of various git commands from shell to a C
program that would fork the same commands. Some of those were converted
over to actual library calls, but much of the pipeline-of-commands
design still remains. Fix some of this by replacing the portion
corresponding to
git diff-index --cached --name-only --diff-filter=A $CTREE >"$a"
git read-tree --reset $CTREE
git update-index --add --stdin <"$a"
rm -f "$a"
into a library function that does the same thing. (The read-tree
--reset was already partially converted over to a library call, but as
an independent piece.) Note here that this came after a merge operation
was performed. The merge machinery always stages anything that cleanly
merges, and the above code only runs if there are no conflicts. Its
purpose is to make it so that when there are no conflicts, all the
changes from the stash are unstaged. However, that causes brand new
files from the stash to become untracked, so the code above first saves
those files off and then re-adds them afterwards.
We replace the whole series of commands with a simple function that will
unstage files that are not newly added. This doesn't fix any bugs in
the usage of these commands, it simply matches the existing behavior but
makes it into a single atomic operation that we can then operate on as a
whole. A subsequent commit will take advantage of this to fix issues
with these commands in sparse-checkouts.
This conversion incidentally fixes t3906.1, because the separate
update-index process would die with the following error messages:
error: uninitialized_sub: is a directory - add files inside instead
fatal: Unable to process path uninitialized_sub
The unstaging of the directory as a submodule meant it was no longer
tracked, and thus as an uninitialized directory it could not be added
back using `git update-index --add`, thus resulting in this error and
early abort. Most of the submodule tests in 3906 continue to fail after
this change, this change was just enough to push the first of those
tests to success.

To generate its filename, the 'git bugreport' builtin asks the system
for the current time with 'localtime()'. Since this uses a shared
buffer, it is not thread-safe.
Even though 'git bugreport' is not multi-threaded, using localtime() can
trigger some static analysis tools to complain, and a quick
$ git grep -oh 'localtime\(_.\)\?' -- **/*.c | sort | uniq -c
shows that the only usage of the thread-unsafe 'localtime' is in a piece
of documentation.
So, convert this instance to use the thread-safe version for
consistency, and to appease some analysis tools.

Multiple "credential-store" backends can race to lock the same
file, causing everybody else but one to fail---reattempt locking
with some timeout to reduce the rate of the failure.
