reftable: file format documentation
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.)

sparse-checkout: avoid staging deletions of all files
sparse-checkout's purpose is to update the working tree to have it
reflect a subset of the tracked files. As such, it shouldn't be
switching branches, making commits, downloading or uploading data, or
staging or unstaging changes. Other than updating the worktree, the
only thing sparse-checkout should touch is the SKIP_WORKTREE bit of the
index. In particular, this sets up a nice invariant: running
sparse-checkout will never change the status of any file in `git status`
(reflecting the fact that we only set the SKIP_WORKTREE bit if the file
is safe to delete, i.e. if the file is unmodified).
Traditionally, we did a _really_ bad job with this goal. The
predecessor to sparse-checkout involved manual editing of
.git/info/sparse-checkout and running `git read-tree -mu HEAD`. That
command would stage and unstage changes and overwrite dirty changes in
the working tree.
The initial implementation of the sparse-checkout command was no better;
it simply invoked `git read-tree -mu HEAD` as a subprocess and had the
same caveats, though this issue came up repeatedly in review comments
and workarounds for the problems were put in place before the feature
was merged[1, 2, 3, 4, 5, 6; especially see 4 & 6].

However, these workarounds, in addition to disabling the feature in a
number of important cases, also missed one special case. I'll get back
to it later.
In the 2.27.0 cycle, the disabling of the feature was lifted by finally
replacing the internal equivalent of `git read-tree -mu HEAD` with
something that did what we wanted: the new update_sparsity() function in
unpack-trees.c that only ever updates SKIP_WORKTREE bits in the index
and updates the working tree to match. This new function handles all
the cases that were problematic for the old implementation, except that
it breaks the same special case that avoided the workarounds of the old
implementation, but broke it in a different way.
So...that brings us to the special case: a git clone performed with
--no-checkout. As per the meaning of the flag, --no-checkout does not
check out any branch, with the implication that you aren't on one and
need to switch to one after the clone. Implementationally, HEAD is
still set (so in some sense you are partially on a branch), but
* the index is "unborn" (non-existent)
* there are no files in the working tree (other than .git/)
* the next time git switch (or git checkout) is run it will run
unpack_trees with `initial_checkout` flag set to true.
It is not until you run, e.g. `git switch <somebranch>` that the index
will be written and files in the working tree populated.
With this special --no-checkout case, the traditional `read-tree -mu
HEAD` behavior would have done the equivalent of acting like checkout --
switch to the default branch (HEAD), write out an index that matches
HEAD, and update the working tree to match. This special case slipped
through the avoid-making-changes checks in the original sparse-checkout
command and thus continued there.
After update_sparsity() was introduced and used (see commit
f56f31af03
("sparse-checkout: use new update_sparsity() function", 2020-03-27)),
the behavior for the --no-checkout case changed: Due to git's
auto-vivification of an empty in-memory index (see do_read_index() and
note that `must_exist` is false), and due to sparse-checkout's
update_working_directory() code to always write out the index after it
was done, we got a new bug. That made it so that sparse-checkout would
switch the repository from a clone with an "unborn" index (i.e. still
needing an initial_checkout), to one that had a recorded index with no
entries. Thus, instead of all the files appearing deleted in `git
status` being known to git as a special artifact of not yet being on a
branch, our recording of an empty index made it suddenly look to git as
though it was definitely on a branch with ALL files staged for deletion!
A subsequent checkout or switch then had to contend with the fact that
it wasn't on an initial_checkout but had a bunch of staged deletions.
Make sure that sparse-checkout changes nothing in the index other than
the SKIP_WORKTREE bit; in particular, when the index is unborn we do not
have any branch checked out so there is no sparsification or
de-sparsification work to do. Simply return from
update_working_directory() early.

diff: discard blob data from stat-unmatched pairs
When performing a tree-level diff against the working tree, we may find
that our index stat information is dirty, so we queue a filepair to be
examined later. If the actual content hasn't changed, we call this a
stat-unmatch; the stat information was out of date, but there's no
actual diff. Normally diffcore_std() would detect and remove these
identical filepairs via diffcore_skip_stat_unmatch(). However, when
"--quiet" is used, we want to stop the diff as soon as we see any
changes, so we check for stat-unmatches immediately in diff_change().
That check may require us to actually load the file contents into the
pair of diff_filespecs. If we find that the pair isn't a stat-unmatch,
then no big deal; we'd likely load the contents later anyway to generate
a patch, do rename detection, etc, so we want to hold on to it. But if
it is a stat-unmatch, then we have no more use for that data; the whole
point is that we're going discard the pair. However, we never free the
allocated diff_filespec data.
In most cases, keeping that data isn't a problem. We don't expect a lot
of stat-unmatch entries, and since we're using --quiet, we'd quit as
soon as we saw such a real change anyway. However, there are extreme
cases where it makes a big difference:
1. We'd generally mmap() the working tree half of the pair. And since
the OS may limit the total number of maps, we can run afoul of this
in large repositories. E.g.:
$ cd linux
$ git ls-files | wc -l
67959
$ sysctl vm.max_map_count
vm.max_map_count = 65530
$ git ls-files | xargs touch ;# everything is stat-dirty!
$ git diff --quiet
fatal: mmap failed: Cannot allocate memory
It should be unusual to have so many files stat-dirty, but it's
possible if you've just run a script like "sed -i" or similar.
After this patch, the above correctly exits with code 0.
2. Even if you don't hit mmap limits, the index half of the pair will
have been pulled from the object database into heap memory. Again
in a clone of linux.git, running:
$ git ls-files | head -n 10000 | xargs touch
$ git diff --quiet
peaks at 145MB heap before this patch, and 94MB after.
This patch solves the problem by freeing any diff_filespec data we
picked up during the "--quiet" stat-unmatch check in diff_changes.
Nobody is going to need that data later, so there's no point holding on
to it. There are a few things to note:
- we could skip queueing the pair entirely, which could in theory save
a little work. But there's not much to save, as we need a
diff_filepair to feed to diff_filespec_check_stat_unmatch() anyway.
And since we cache the result of the stat-unmatch checks, a later
call to diffcore_skip_stat_unmatch() call will quickly skip over
them. The diffcore code also counts up the number of stat-unmatched
pairs as it removes them. It's doubtful any callers would care about
that in combination with --quiet, but we'd have to reimplement the
logic here to be on the safe side. So it's not really worth the
trouble.
- I didn't write a test, because we always produce the correct output
unless we run up against system mmap limits, which are both
unportable and expensive to test against. Measuring peak heap
would be interesting, but our perf suite isn't yet capable of that.
- note that diff without "--quiet" does not suffer from the same
problem. In diffcore_skip_stat_unmatch(), we detect the stat-unmatch
entries and drop them immediately, so we're not carrying their data
around.
- you _can_ still trigger the mmap limit problem if you truly have
that many files with actual changes. But it's rather unlikely. The
stat-unmatch check avoids loading the file contents if the sizes
don't match, so you'd need a pretty trivial change in every single
file. Likewise, inexact rename detection might load the data for
many files all at once. But you'd need not just 64k changes, but
that many deletions and additions. The most likely candidate is
perhaps break-detection, which would load the data for all pairs and
keep it around for the content-level diff. But again, you'd need 64k
actually changed files in the first place.
So it's still possible to trigger this case, but it seems like "I
accidentally made all my files stat-dirty" is the most likely case
in the real world.

fast-import: add new --date-format=raw-permissive format
There are multiple repositories in the wild with random, invalid
timezones. Most notably is a commit from rails.git with a timezone of
"+051800"[1]. A few searches will find other repos with that same
invalid timezone as well. Further, Peff reports that GitHub relaxed
their fsck checks in August 2011 to accept any timezone value[2], and
there have been multiple reports to filter-repo about fast-import
crashing while trying to import their existing repositories since they
had timezone values such as "-
7349423" and "-
43455309"[3].
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
new script. For them, the check may help them avoid accidentally
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
be imported.

checkout -p: handle new files correctly
The original patch selection code was written for `git add -p`, and the
fundamental unit on which it works is a hunk.
We hacked around that to handle deletions back in
24ab81ae4d
(add-interactive: handle deletion of empty files, 2009-10-27). But `git
add -p` would never see a new file, since we only consider the set of
tracked files in the index.
However, since the same machinery was used for `git checkout -p` &
friends, we can see new files.
Handle this case specifically, adding a new prompt for it that is
modeled after the `deleted file` case.
This also fixes the problem where added _empty_ files could not be
staged via `git checkout -p`.

sparse: allow '{ 0 }' to be used without warnings
In standard C, '{ 0 }' can be used as an universal zero-initializer.
However, Sparse complains if this is used on a type where the first
member (possibly nested) is a pointer since Sparse purposely wants
to warn when '0' is used to initialize a pointer type.
Legitimaly, it's desirable to be able to use '{ 0 }' as an idiom
without these warnings [1,2]. To allow this, an option have now
been added to Sparse:
537e3e2dae univ-init: conditionally accept { 0 } without warnings
So, add this option to the SPARSE_FLAGS variable.
Note: The option have just been added to Sparse. So, to benefit
now from this patch it's needed to use the latest Sparse
source from kernel.org. The option will simply be ignored
by older versions of Sparse.

stateless-connect: send response end packet
Currently, remote-curl acts as a proxy and blindly forwards packets
between an HTTP server and fetch-pack. In the case of a stateless RPC
connection where the connection is terminated before the transaction is
complete, remote-curl will blindly forward the packets before waiting on
more input from fetch-pack. Meanwhile, fetch-pack will read the
transaction and continue reading, expecting more input to continue the
transaction. This results in a deadlock between the two processes.
This can be seen in the following command which does not terminate:
$ git -c protocol.version=2 clone https://github.com/git/git.git --shallow-since=
20151012
Cloning into 'git'...
whereas the v1 version does terminate as expected:
$ git -c protocol.version=1 clone https://github.com/git/git.git --shallow-since=
20151012
Cloning into 'git'...
fatal: the remote end hung up unexpectedly
Instead of blindly forwarding packets, make remote-curl insert a
response end packet after proxying the responses from the remote server
when using stateless_connect(). On the RPC client side, ensure that each
response ends as described.
A separate control packet is chosen because we need to be able to
differentiate between what the remote server sends and remote-curl's
control packets. By ensuring in the remote-curl code that a server
cannot send response end packets, we prevent a malicious server from
being able to perform a denial of service attack in which they spoof a
response end packet and cause the described deadlock to happen.

remote-curl: error on incomplete packet
Currently, remote-curl acts as a proxy and blindly forwards packets
between an HTTP server and fetch-pack. In the case of a stateless RPC
connection where the connection is terminated with a partially written
packet, remote-curl will blindly send the partially written packet
before waiting on more input from fetch-pack. Meanwhile, fetch-pack will
read the partial packet and continue reading, expecting more input. This
results in a deadlock between the two processes.
For a stateless connection, inspect packets before sending them and
error out if a packet line packet is incomplete.

t5608: avoid say() and use "skip_all" instead for consistency
Printing a message directly to stdout could affect TAP processing
and is not really needed, as there is a standard way to skip all
tests that could be used instead, while printing an equivalent
message.
While at it; update the message to better reflect that since
a85efb5985 (t5608-clone-2gb.sh: turn GIT_TEST_CLONE_2GB into a bool,
2019-11-22), the enabling variable should be a recognized boolean
(ex: true, false, 1, 0) and get rid of the prerequisite that used
to guard all the tests, since "skip_all" is just much faster and
idempotent.

checkout: improve error messages for -b with extra argument
When we try to create a branch "foo" based on "origin/master" and give
git commit -b an extra unsupported argument "bar", it confusingly
reports:
$ git checkout -b foo origin/master bar
fatal: 'bar' is not a commit and a branch 'foo' cannot be created from it
$ git checkout --track -b foo origin/master bar
fatal: 'bar' is not a commit and a branch 'foo' cannot be created from it
That's wrong, because it very well understands that "origin/master" is
supposed to be the start point for the new branch and not "bar". Check
if we got a commit and show more fitting messages in that case instead:
$ git checkout -b foo origin/master bar
fatal: Cannot update paths and switch to branch 'foo' at the same time.
$ git checkout --track -b foo origin/master bar
fatal: '--track' cannot be used with updating paths

checkout: add tests for -b and --track
Test git checkout -b with and without --track and demonstrate unexpected
error messages when it's given an extra (i.e. unsupported) path
argument. In both cases it reports:
$ git checkout -b foo origin/master bar
fatal: 'bar' is not a commit and a branch 'foo' cannot be created from it
The problem is that the start point we gave for the new branch is
"origin/master" and "bar" is just some extra argument -- it could even
be a valid commit, which would make the message even more confusing. We
have more fitting error messages in git commit, but get confused; use
the text of the rights ones in the tests.

06f5608c14 (bisect--helper: `bisect_start` shell function partially in C,

in a segfault under a bad syntax call for start with custom terms.
Detect if there are enough arguments left in the command line to use for
--term-{old,good,new,bad} and abort with the same syntax error the original

completion: don't override given stash subcommand with -p
df70b190 (completion: make stash -p and alias for stash push -p,
2018-04-20) wanted to make sure "git stash -p <TAB>" offers the same
completion as "git stash push -p <TAB>", but it did so by forcing the
$subcommand to be "push" whenever then "-p" option is found on the
command line.
This harms any subcommand that can take the "-p" option---even when the
subcommand is explicitly given, e.g. "git stash show -p", the code added
by the change would overwrite the $subcommand the user gave us.
Fix it by making sure that the defaulting to "push" happens only when
there is no $subcommand given yet.

Do that by factoring out the test code into a function to allow for more
concise notation in the form of parameters indicating names of trees
(with trailing slash) and blobs (without trailing slash) in no

case as a second function call.
