We could instead have just removed the following bitfields
from the struct:
unsigned use_thin_pack : 1;
unsigned use_ofs_delta : 1;
unsigned no_progress : 1;
unsigned use_include_tag : 1;
but using them makes it possible to remove a number of static

This is a behavior change, as we accidentally used to let values
in those bitfields propagate from one v2 "fetch" command to
another for ssh/git/file connections (but not for http). That's
fixing a bug, but one nobody is likely to see, because it would
imply the client sending different capabilities for each request.

done inside of commit-graph.c.

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stat-unmatch; the stat information was out of date, but there's no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.

In the case of git switch, after we complete the argument, there is

completion: improve handling of -c/-C and -b/-B in switch/checkout
A previous commit added several test cases highlighting the subpar
completion logic for -c/-C and -b/-B when completing git switch and git
checkout.
In order to distinguish completing the argument vs the start-point for
this option, we now use the wordlist to determine the previous full word
on the command line.
If it's -c or -C (-b/-B for checkout), then we know that we are
completing the argument for the branch name.
Given that a user who already knows the branch name they want to
complete will simply not use completion, it makes sense to complete the
small subset of local branches when completing the argument for -c/-C.
In all other cases, if -c/-C are on the command line but are not the
most recent option, then we must be completing a start-point, and should
allow completing against all references.

completion: improve handling of --track in switch/checkout
Current completion for the --track option of git switch and git checkout
is sub par. In addition to the DWIM logic of a bare branch name, --track
has DWIM logic to convert specified remote/branch names into a local
branch tracking that remote. For example
$git switch --track origin/master
This will create a local branch name master, that tracks the master
branch of the origin remote.
In fact, git switch --track on its own will not accept other forms of
references. These must instead be specified manually via the -c/-C/-b/-B
options.
Introduce __git_remote_heads() and the "remote-heads" mode for
__git_complete_refs. Use this when the --track option is provided while
completing in _git_switch and _git_checkout. Just as in the --detach
case, we never enable DWIM mode for --track, because it doesn't make
sense.
It should be noted that completion support is still a bit sub par when
it comes to handling -c/-C and --orphan. This will be resolved in
a future change.

completion: improve completion for git switch with no options
Add a new --mode option to __git_complete_refs, which allows changing
the behavior to call __git_heads instead of __git_refs.
By passing --mode=heads, __git_complete_refs will only output local
branches. This enables using "--mode=heads --dwim" to enable listing
local branches and the remote unique branch names for DWIM.
Refactor completion support to use the new mode option, rather than
calling __git_heads directly. This has the advantage that we can now
correctly allow local branches along with suitable DWIM refs, rather
than only allowing DWIM when we complete all references.
Choose what mode it uses when calling __git_complete_refs. If -d or
--detach have been provided, then simply complete all refs, but
*without* the DWIM option as these DWIM names won't work properly in
--detach mode.
Otherwise, call __git_complete_refs with the default dwim_opt value and
use the new "heads" mode.
In this way, the basic support for completing just "git switch <TAB>"
will result in only local branches and remote unique names for DWIM.

completion: improve handling of DWIM mode for switch/checkout
A new helper, __git_find_last_on_cmdline is introduced, similar to the
already existing __git_find_on_cmdline, but which operates in reverse,

Use this in a new __git_checkout_default_dwim_mode() function that will
determine when to enable listing of DWIM remote branches.
The __git_find_last_on_cmdline() function is used to determine which
--guess or --no-guess is in effect. If either one is provided, then we
unconditionally enable or disable the DWIM mode based on the last
provided option.
If neither --guess nor --no-guess is provided, then we check for
--no-track, and finally for GIT_COMPLETION_CHECKOUT_NO_GUESS=1.
This function is then used in _git_switch and _git_checkout to improve
the handling for when we enable listing of these DWIM remote branches.
This new logic is more robust, as we will correctly identify superseded
options, and ensure that both _git_switch and _git_checkout enable DWIM
in similar ways.
We can now update a few tests to indicate they pass. A few of the tests
previously added to highlight issues with the old DWIM logic still fail.

completion: perform DWIM logic directly in __git_complete_refs
__git_complete_refs is the main function used for completing references.
It is primarily used as a wrapper around __git_refs, and is easier to
extend since its arguments are option-like.
One major downside of __git_complete_refs and __git_refs currently, is
the lack of ability to complete only a subset of refs such as branches
(refs/heads) or tags (refs/tags).
Normally, a caller might just decide to use __git_heads() or
__git_tags(). However, in the case of git-switch, it is useful to
complete both branches *and* DWIM remote branch names.
Due to the complexity and implementation of __git_refs, it is not easy
to extend it to support listing only a subset of references.
Instead, we can extend __git_complete_refs to do this. For this to be
done, we must first ensure that "--dwim" support is not tied to calling
__git_refs.
Instead of passing $dwim into __git_refs, we can implement
a __gitcomp_direct_append function which can append to COMPREPLY after
a call to __gitcomp_direct.
If --dwim is passed to __git_complete_refs, use __gitcomp_direct_append
to add the output of __git_dwim_remote_heads to the completion list.
In this way, --dwim support is now independent of calling __git_refs.
A future change will add an additional option to control what set of
references __git_complete_refs will output.

The __git_complete_refs uses the "--track" option to specify when to

themselves have '--track' as an argument. Additionally, the completion

Use the option '--dwim' instead, indicating this is about enabling or

track_opt to dwim_opt to further reduce the confusion when reading the

completion: add tests showing subpar DWIM logic for switch/checkout
When provided with a single argument that is the name of a remote branch
that does not yet exist locally, both git switch and git checkout can
interpret this as a request to create a local branch that tracks that
remote branch. We call this behavior "Do What I Mean", or DWIM for
short.
To aid in using this DWIM, it makes sense for completion to list these
unique remote branch names when completing possible arguments for git
switch and git checkout. Indeed, both _git_checkout and _git_switch
implement support for completing such DWIM branch names.
In other words, in addition to the usual completions provided for git
switch, this "DWIM" logic means completion will include the names of
branches on remotes that are unique and thus there can be no ambiguity
of which remote to track when creating the local branch.
However, the DWIM logic is not always active. Many options, such as
--no-guess, --no-track, and --track disable this DWIM logic, as they
cause git switch and git checkout to behave in different modes.
Additionally, some completion users do not wish to have tab completion
include these remote names by default, and thus introduced
GIT_COMPLETION_CHECKOUT_NO_GUESS as an optional way to configure the
completion support to disable this feature of completion support.
For this reason, _git_checkout and _git_switch have many rules about
when to enable or disable completing of these remote refs. The two
commands follow similar but not identical rules.
Set aside the question of command modes that do not accept this DWIM
logic (--track, -c, --orphan, --detach) for now. Thinking just about the
main mode of git checkout and git switch, the following guidelines will
help explain the basic rules we ought to support when deciding whether
to list the remote branches for DWIM in completion.
1. if --guess is enabled, we should list DWIM remote branch names, even
if something else would disable it
2. if --no-guess, --no-track or GIT_COMPLETION_CHECKOUT_NO_GUESS=1,
then we should disable listing DWIM remote branch names.
3. Since the '--guess' option is a boolean option, a later --guess
should override --no-guess, and a later --no-guess should override
--guess.
Putting all of these together, add some tests that highlight the
expected behavior of this DWIM logic.

When provided with no options, git switch only allows switching between
branches. The one exception to this is the "Do What I Mean" logic that
allows a unique remote branch name to be interpreted as a request to
create a branch of the same name that is tracking that remote branch.
Unfortunately, the logic for the completion of git switch results in
completing not just branch names, but also pseudorefs like HEAD, tags,
and fully specified <remote>/<branch> references.
For example, we currently complete the following:
$git switch <TAB>
HEAD
branch-in-other
master
master-in-other
matching-branch
matching-tag
other/branch-in-other
other/master-in-other
Indeed, if one were to attempt to use git switch with some of these
provided options, git will reject the request:
$git switch HEAD
fatal: a branch is expected, got 'HEAD
$git switch matching-tag
fatal: a branch is expected, got tag 'matching-tag'
$git switch other/branch-in-other
fatal: a branch is expected, got remote branch 'other/branch-in-other'
Ideally, git switch without options ought to complete only words which
will be accepted. Without options, this means to list local branch names
and the unique remote branch names without their remote name pre-pended.
$git switch <TAB>
branch-in-other
master
master-in-other

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.

gitfaq: avoid validation error with older asciidoc

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.

checkout: improve error messages for -b with extra argument
When we try to create a branch "foo" based on "origin/master" and give

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

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

This harms any subcommand that can take the "-p" option---even when the
