of this section header grew by two characters but we didn't adjust the

The description of `git diff` goes through several different invocations
(numbering added by me):
1. git diff [<options>] [--] [<path>...]
2. git diff [<options>] --no-index [--] <path> <path>
3. git diff [<options>] --cached [<commit>] [--] [<path>...]
4. git diff [<options>] <commit> [--] [<path>...]
5. git diff [<options>] <commit> <commit> [--] [<path>...]
6. git diff [<options>] <commit>..<commit> [--] [<path>...]
7. git diff [<options>] <commit> <commit>... <commit> [--] [<path>...]
8. git diff [<options>] <commit>...<commit> [--] [<path>...]
It then goes on to say that "all of the <commit> in the above
description, except in the last two forms that use '..' notations, can
be any <tree>". The "last two" actually refers to 6 and 8. This got out
of sync in commit b7e10b2ca2 ("Documentation: usage for diff combined
commits", 2020-06-12) which added item 7 to the mix.
As a further complication, after b7e10b2ca2 we also have some potential
confusion around "the '..' notation". The "..[.]" in items 6 and 8 are
part of the rev notation, whereas the "..." in item 7 is manpage
language for "one or more".
Move item 6 down, i.e., to between 7 and 8, to restore the ordering.
Because 6 refers to 5 ("synonymous to the previous form") we need to
tweak the language a bit.
An added bonus of this commit is that we're trying to steer users away
from `git diff <commit>..<commit>` and moving it further down probably
doesn't hurt.

Commit b7e10b2ca2 ("Documentation: usage for diff combined commits",
2020-06-12) modified the synopsis by adding an optional "[<commit>...]"
to
'git diff' [<options>] <commit> <commit> [--] [<path>...]
to effectively add
'git diff' [<options>] <commit> <commit>... <commit> [--] [<path>...]
as another valid invocation. Which makes sense.
Further down, in the description, it left the existing entry for
'git diff' [<options>] <commit> <commit> [--] [<path>...]
intact and added a new entry on
'git diff' [<options>] <commit> [<commit>...] <commit> [--] [<path>...]
where it says that "[t]his form is to view the results of a merge
commit" and details how "the first listed commit must be the merge
itself". But one possible instantiation of this form is `git diff
<commit> <commit>` for which the added text doesn't really apply.
Remove the brackets so that we lose this overlap between the two
descriptions. We can still use the more compact representation in the
synopsis.

The fetch.writeCommitGraph feature makes fetches write out a commit
graph file for the newly downloaded pack on fetch. This improves the
performance of various commands that would perform a revision walk and
eventually ought to be the default for everyone. To prepare for that
future, it's enabled by default for users that set
feature.experimental=true to experience such future defaults.
Alas, for --unshallow fetches from a shallow clone it runs into a
snag: by the time Git has fetched the new objects and is writing a
commit graph, it has performed a revision walk and r->parsed_objects
contains information about the shallow boundary from *before* the
fetch. The commit graph writing code is careful to avoid writing a
commit graph file in shallow repositories, but the new state is not
shallow, and the result is that from that point on, commands like "git
log" make use of a newly written commit graph file representing a
fictional history with the old shallow boundary.
We could fix this by making the commit graph writing code more careful
to avoid writing a commit graph that could have used any grafts or
shallow state, but it is possible that there are other pieces of
mutated state that fetch's commit graph writing code may be relying
on. So disable it in the feature.experimental configuration.
Google developers have been running in this configuration (by setting
fetch.writeCommitGraph=false in the system config) to work around this
bug since it was discovered in April. Once the fix lands, we'll
enable fetch.writeCommitGraph=true again to give it some early testing
before rolling out to a wider audience.
In other words:
- this patch only affects behavior with feature.experimental=true
- it makes feature.experimental match the configuration Google has
been using for the last few months, meaning it would leave users in
a better tested state than without it
- this should improve testing for other features guarded by
feature.experimental, by making feature.experimental safer to use

After you anonymize a repository, it can be hard to find which commits
correspond between the original and the result, and thus hard to
reproduce commands that triggered bugs in the original.
Let's make it possible to seed the anonymization map. This lets users
either:
- mark names to be retained as-is, if they don't consider them secret
(in which case their original commands would just work)
- map names to new values, which lets them adapt the reproduction
recipe to the new names without revealing the originals
The implementation is fairly straight-forward. We already store each
anonymized token in a hashmap (so that the same token appearing twice is
converted to the same result). We can just introduce a new "seed"
hashmap which is consulted first.
This does make a few more promises to the user about how we'll anonymize
things (e.g., token-splitting pathnames). But it's unlikely that we'd
want to change those rules, even if the actual anonymization of a single
token changes. And it makes things much easier for the user, who can
unblind only a directory name without having to specify each path within
it.
One alternative to this approach would be to anonymize as we see fit,
and then dump the whole refname and pathname mappings to a file. This
does work, but it's a bit awkward to use (you have to manually dig the
items you care about out of the mapping).

When `remote.<name>.branch` is not configured, `git submodule update`
currently falls back to using the branch name `master`. A much better
idea, however, is to use the remote `HEAD`: on all Git servers running
reasonably recent Git versions, the symref `HEAD` points to the main
branch.
Note: t7419 demonstrates that there _might_ be use cases out there that
_expect_ `git submodule update --remote` to update submodules to the
remote `master` branch even if the remote `HEAD` points to another
branch. Arguably, this patch makes the behavior more intuitive, but
there is a slight possibility that this might cause regressions in
obscure setups.
Even so, it should be okay to fix this behavior without anything like a
longer transition period:
- The `git submodule update --remote` command is not really common.
- Current Git's behavior when running this command is outright
confusing, unless the remote repository's current branch _is_ `master`
(in which case the proposed behavior matches the old behavior).
- If a user encounters a regression due to the changed behavior, the fix
is actually trivial: setting `submodule.<name>.branch` to `master`
will reinstate the old behavior.

The low-level reference transactions used to update references are
currently completely opaque to the user. While certainly desirable in
most usecases, there are some which might want to hook into the
transaction to observe all queued reference updates as well as observing
the abortion or commit of a prepared transaction.
One such usecase would be to have a set of replicas of a given Git
repository, where we perform Git operations on all of the repositories
at once and expect the outcome to be the same in all of them. While
there exist hooks already for a certain subset of Git commands that
could be used to implement a voting mechanism for this, many others
currently don't have any mechanism for this.
The above scenario is the motivation for the new "reference-transaction"
hook that reaches directly into Git's reference transaction mechanism.
The hook receives as parameter the current state the transaction was
moved to ("prepared", "committed" or "aborted") and gets via its
standard input all queued reference updates. While the exit code gets
ignored in the "committed" and "aborted" states, a non-zero exit code in
the "prepared" state will cause the transaction to be aborted
prematurely.
Given the usecase described above, a voting mechanism can now be
implemented via this hook: as soon as it gets called, it will take all
of stdin and use it to cast a vote to a central service. When all
replicas of the repository agree, the hook will exit with zero,
otherwise it will abort the transaction by returning non-zero. The most
important upside is that this will catch _all_ commands writing
references at once, allowing to implement strong consistency for
reference updates via a single mechanism.
In order to test the impact on the case where we don't have any
"reference-transaction" hook installed in the repository, this commit
introduce two new performance tests for git-update-refs(1). Run against
an empty repository, it produces the following results:
Test origin/master HEAD
--------------------------------------------------------------------
1400.2: update-ref 2.70(2.10+0.71) 2.71(2.10+0.73) +0.4%
1400.3: update-ref --stdin 0.21(0.09+0.11) 0.21(0.07+0.14) +0.0%
The performance test p1400.2 creates, updates and deletes a branch a
thousand times, thus averaging runtime of git-update-refs over 3000
invocations. p1400.3 instead calls `git-update-refs --stdin` three times
and queues a thousand creations, updates and deletes respectively.
As expected, p1400.3 consistently shows no noticeable impact, as for
each batch of updates there's a single call to access(3P) for the
negative hook lookup. On the other hand, for p1400.2, one can see an
impact caused by this patchset. But doing five runs of the performance
tests where each one was run with GIT_PERF_REPEAT_COUNT=10, the overhead
ranged from -1.5% to +1.1%. These inconsistent performance numbers can
be explained by the overhead of spawning 3000 processes. This shows that
the overhead of assembling the hook path and executing access(3P) once
to check if it's there is mostly outweighed by the operating system's
overhead.

Ignoring the sparse-checkout feature momentarily, if one has a submodule and
creates local branches within it with unpushed changes and maybe adds some
untracked files to it, then we would want to avoid accidentally removing such
a submodule. So, for example with git.git, if you run
git checkout v2.13.0
then the sha1collisiondetection/ submodule is NOT removed even though it
did not exist as a submodule until v2.14.0. Similarly, if you only had
v2.13.0 checked out previously and ran
git checkout v2.14.0
the sha1collisiondetection/ submodule would NOT be automatically
initialized despite being part of v2.14.0. In both cases, git requires
submodules to be initialized or deinitialized separately. Further, we
also have special handling for submodules in other commands such as
clean, which requires two --force flags to delete untracked submodules,
and some commands have a --recurse-submodules flag.
sparse-checkout is very similar to checkout, as evidenced by the similar
name -- it adds and removes files from the working copy. However, for
the same avoid-data-loss reasons we do not want to remove a submodule
from the working copy with checkout, we do not want to do it with
sparse-checkout either. So submodules need to be separately initialized
or deinitialized; changing sparse-checkout rules should not
automatically trigger the removal or vivification of submodules.
I believe the previous wording in git-sparse-checkout.txt about
submodules was only about this particular issue. Unfortunately, the
previous wording could be interpreted to imply that submodules should be
considered active regardless of sparsity patterns. Update the wording
to avoid making such an implication. It may be helpful to consider two
example situations where the differences in wording become important:
In the future, we want users to be able to run commands like
git clone --sparse=moduleA --recurse-submodules $REPO_URL
and have sparsity paths automatically set up and have submodules *within
the sparsity paths* be automatically initialized. We do not want all
submodules in any path to be automatically initialized with that
command.
Similarly, we want to be able to do things like
git -c sparse.restrictCmds grep --recurse-submodules $REV $PATTERN
and search through $REV for $PATTERN within the recorded sparsity
patterns. We want it to recurse into submodules within those sparsity
patterns, but do not want to recurse into directories that do not match
the sparsity patterns in search of a possible submodule.

"git worktree add" takes special care to avoid creating a new worktree
at a location already registered to an existing worktree even if that
worktree is missing (which can happen, for instance, if the worktree
resides on removable media). "git worktree move", however, is not so
careful when validating the destination location and will happily move
the source worktree atop the location of a missing worktree. This leads
to the anomalous situation of multiple worktrees being associated with
the same path, which is expressly forbidden by design. For example:
$ git clone foo.git
$ cd foo
$ git worktree add ../bar
$ git worktree add ../baz
$ rm -rf ../bar
$ git worktree move ../baz ../bar
$ git worktree list
.../foo beefd00f [master]
.../bar beefd00f [bar]
.../bar beefd00f [baz]
$ git worktree remove ../bar
fatal: validation failed, cannot remove working tree:
'.../bar' does not point back to '.git/worktrees/bar'
Fix this shortcoming by enhancing "git worktree move" to perform the
same additional validation of the destination directory as done by "git
worktree add".
While at it, add a test to verify that "git worktree move" won't move a
worktree atop an existing (non-worktree) path -- a restriction which has
always been in place but was never tested.

Shawn Pearce explains:
Some repositories contain a lot of references (e.g. android at 866k,
rails at 31k). The reftable format provides:
- Near constant time lookup for any single reference, even when the
repository is cold and not in process or kernel cache.
- Near constant time verification if a SHA-1 is referred to by at least
one reference (for allow-tip-sha1-in-want).
- Efficient lookup of an entire namespace, such as `refs/tags/`.
- Support atomic push `O(size_of_update)` operations.
- Combine reflog storage with ref storage.
This file format spec was originally written in July, 2017 by Shawn
Pearce. Some refinements since then were made by Shawn and by Han-Wen
Nienhuys based on experiences implementing and experimenting with the
format. (All of this was in the context of our work at Google and
Google is happy to contribute the result to the Git project.)

invalid timezone as well. Further, Peff reports that GitHub relaxed

crashing while trying to import their existing repositories since they

The existing check on timezone values inside fast-import may prove
useful for people who are crafting fast-import input by hand or with a

recording invalid dates. (Note that this check is rather simplistic and
there are still several forms of invalid dates that fast-import does not
check for: dates in the future, timezone values with minutes that are
not divisible by 15, and timezone values with minutes that are 60 or
greater.) While this simple check may have some value for those users,
other users or tools will want to import existing repositories as-is.
Provide a --date-format=raw-permissive format that will not error out on
these otherwise invalid timezones so that such existing repositories can

To set the default hash algorithm you can set the `GIT_DEFAULT_HASH`
environment variable. In the documentation this variable is named
`GIT_DEFAULT_HASH_ALGORITHM`, which is incorrect.

The explanation of the `--show-pulls` option added in commit 8d049e182e
("revision: --show-pulls adds helpful merges", 2020-04-10) consists of
several paragraphs and we use "+" throughout to tie them together in one
long chain of list continuations. Only thing is, we're not in any kind
of list, so these pluses end up being rendered literally.
The preceding few paragraphs describe `--ancestry-path` and there we
*do* have a list, since we've started one with `--ancestry-path::`. In
fact, we have several such lists for all the various history-simplifying
options we're discussing earlier in this file.
Thus, we're missing a list both from a consistency point of view and
from a practical rendering standpoint.
Let's start a list for `--show-pulls` where we start actually discussing
the option, and keep the paragraphs preceding it out of that list. That
is, drop all those pluses before the new list we're adding here.
