Commit 6b1db43109 ("clean: teach clean -d to preserve ignored paths",
2017-05-23) added the following code block (among others) to git-clean:
if (remove_directories)
dir.flags |= DIR_SHOW_IGNORED_TOO | DIR_KEEP_UNTRACKED_CONTENTS;
The reason for these flags is well documented in the commit message, but
isn't obvious just from looking at the code. Add some explanations to
the code to make it clearer.
Further, it appears git-2.26 did not correctly handle this combination
of flags from git-clean. With both these flags and without
DIR_SHOW_IGNORED_TOO_MODE_MATCHING set, git is supposed to recurse into
all untracked AND ignored directories. git-2.26.0 clearly was not doing
that. I don't know the full reasons for that or whether git < 2.27.0
had additional unknown bugs because of that misbehavior, because I don't
feel it's worth digging into. As per the huge changes and craziness
documented in commit 8d92fb2927 ("dir: replace exponential algorithm
with a linear one", 2020-04-01), the old algorithm was a mess and was
thrown out. What I can say is that git-2.27.0 correctly recurses into
untracked AND ignored directories with that combination.
However, in clean's case we don't need to recurse into ignored
directories; that is just a waste of time. Thus, when git-2.27.0
started correctly handling those flags, we got a performance regression
report. Rather than relying on other bugs in fill_directory()'s former
logic to provide the behavior of skipping ignored directories, make use
of the DIR_SHOW_IGNORED_TOO_MODE_MATCHING value specifically added in
commit eec0f7f2b7 ("status: add option to show ignored files
differently", 2017-10-30) for this purpose.

I spent a long time trying to figure out how and whether the code worked
with different values of ignore, ignore_only, and remove_directories.
After lots of time setting up lots of testcases, sifting through lots of
print statements, and walking through the debugger, I finally realized
that one piece of code related to how it was all setup was found in
clean.c rather than dir.c. Make a change that would have made it easier
for me to do the extra testing by putting this handling in one spot.

dir.h documented quite clearly that DIR_SHOW_IGNORED and
DIR_SHOW_IGNORED_TOO are mutually exclusive, with a big comment to this
effect by the definition of both enum values. However, a command like
git clean -fx $DIR
would set both values for dir.flags. I _think_ it happened to work
because:
* As dir.h points out, DIR_KEEP_UNTRACKED_CONTENTS only takes effect
if DIR_SHOW_IGNORED_TOO is set.
* As coded, I believe DIR_SHOW_IGNORED would just happen to take
precedence over DIR_SHOW_IGNORED_TOO in the code as currently
constructed.
Which is a long way of saying "we just got lucky".
Fix clean.c to avoid setting these mutually exclusive values at the same
time, and add a check to dir.c that will throw a BUG() to prevent anyone
else from making this mistake.

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.

When git diff is given a symmetric difference A...B, it chooses
some merge base from the two specified commits (as documented).
This fails, however, if there is *no* merge base: instead, you
see the differences between A and B, which is certainly not what
is expected.
Moreover, if additional revisions are specified on the command
line ("git diff A...B C"), the results get a bit weird:
* If there is a symmetric difference merge base, this is used
as the left side of the diff. The last final ref is used as
the right side.
* If there is no merge base, the symmetric status is completely
lost. We will produce a combined diff instead.
Similar weirdness occurs if you use, e.g., "git diff C A...B D".
Likewise, using multiple two-dot ranges, or tossing extra
revision specifiers into the command line with two-dot ranges,
or mixing two and three dot ranges, all produce nonsense.
To avoid all this, add a routine to catch the range cases and
verify that that the arguments make sense. As a side effect,
produce a warning showing *which* merge base is being used when
there are multiple choices; die if there is no merge base.

Teach upload-pack to send part of its packfile response as URIs.
An administrator may configure a repository with one or more
"uploadpack.blobpackfileuri" lines, each line containing an OID, a pack
hash, and a URI. A client may configure fetch.uriprotocols to be a
comma-separated list of protocols that it is willing to use to fetch
additional packfiles - this list will be sent to the server. Whenever an
object with one of those OIDs would appear in the packfile transmitted
by upload-pack, the server may exclude that object, and instead send the
URI. The client will then download the packs referred to by those URIs
before performing the connectivity check.

Whenever a fetch results in a packfile being downloaded, a .keep file is
generated, so that the packfile can be preserved (from, say, a running
"git repack") until refs are written referring to the contents of the
packfile.
In a subsequent patch, a successful fetch using protocol v2 may result
in more than one .keep file being generated. Therefore, teach
fetch_pack() and the transport mechanism to support multiple .keep
files.
Implementation notes:
- builtin/fetch-pack.c normally does not generate .keep files, and thus
is unaffected by this or future changes. However, it has an
undocumented "--lock-pack" feature, used by remote-curl.c when
implementing the "fetch" remote helper command. In keeping with the
remote helper protocol, only one "lock" line will ever be written;
the rest will result in warnings to stderr. However, in practice,
warnings will never be written because the remote-curl.c "fetch" is
only used for protocol v0/v1 (which will not generate multiple .keep
files). (Protocol v2 uses the "stateless-connect" command, not the
"fetch" command.)
- connected.c has an optimization in that connectivity checks on a ref
need not be done if the target object is in a pack known to be
self-contained and connected. If there are multiple packfiles, this
optimization can no longer be done.

finish_http_pack_request() does multiple tasks, including some
housekeeping on a struct packed_git - (1) closing its index, (2)
removing it from a list, and (3) installing it. These concerns are
independent of fetching a pack through HTTP: they are there only because
(1) the calling code opens the pack's index before deciding to fetch it,
(2) the calling code maintains a list of packfiles that can be fetched,
and (3) the calling code fetches it in order to make use of its objects
in the same process.
In preparation for a subsequent commit, which adds a feature that does
not need any of this housekeeping, remove (1), (2), and (3) from
finish_http_pack_request(). (2) and (3) are now done by a helper
function, and (1) is the responsibility of the caller (in this patch,
done closer to the point where the pack index is opened).

When Git fetches a pack using dumb HTTP, (among other things) it invokes
index-pack on a ".pack.temp" packfile, specifying the filename as an
argument.
A future commit will require the aforementioned invocation of index-pack
to also generate a "keep" file. To use this, we either have to use
index-pack's naming convention (because --keep requires the pack's
filename to end with ".pack") or to pass the pack through stdin. Of the
two, it is simpler to pass the pack through stdin.
Thus, teach http to pass --stdin to index-pack. As a bonus, the code is
now simpler.

"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'

same additional validation of the destination directory as done by "git

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.)
