The revision traversal machinery typically processes and returns all
children before any parent. fast-export needs to operate in the
reverse fashion, handling parents before any of their children in
order to build up the history starting from the root commit(s). This
would be a clear case where we could just use the revision traversal
machinery's "reverse" option to achieve this desired affect.
However, this wasn't what the code did. It added its own array for
queuing. The obvious hand-rolled solution would be to just push all
the commits into the array and then traverse afterwards, but it didn't
quite do that either. It instead attempted to process anything it
could as soon as it could, and once it could, check whether it could
process anything that had been queued. As far as I can tell, this was
an effort to save a little memory in the case of multiple root commits
since it could process some commits before queueing all of them. This
involved some helper functions named has_unshown_parent() and
handle_tail(). For typical invocations of fast-export, this
alternative essentially amounted to a hand-rolled method of reversing
the commits -- it was a bunch of work to duplicate the revision
traversal machinery's "reverse" option.
This hand-rolled reversing mechanism is actually somewhat difficult to
reason about. It takes some time to figure out how it ensures in
normal cases that it will actually process all traversed commits
(rather than just dropping some and not printing anything for them).
And it turns out there are some cases where the code does drop commits
without handling them, and not even printing an error or warning for
the user. Due to the has_unshown_parent() checks, some commits could
be left in the array at the end of the "while...get_revision()" loop
which would be unprocessed. This could be triggered for example with
git fast-export main -- --first-parent
or non-sensical traversal rules such as
git fast-export main -- --grep=Merge --invert-grep
While most traversals that don't include all parents should likely
trigger errors in fast-export (or at least require being used in
combination with --reference-excluded-parents), the --first-parent
traversal is at least reasonable and it'd be nice if it didn't just drop
commits. It'd also be nice for future readers of the code to have a
simpler "reverse traversal" mechanism. Use the "reverse" option of the
revision traversal machinery to achieve both.
Even for the non-sensical traversal flags like the --grep one above,
this would be an improvement. For example, in that case, the code
previously would have silently truncated history to only those commits
that do not have an ancestor containing "Merge" in their commit message.
After this code change, that case would include all commits without
"Merge" in their commit message -- but any commit that previously had a
"Merge"-mentioning parent would lose that parent
(likely resulting in many new root commits). While the new behavior is
still odd, it is at least understandable given that
--reference-excluded-parents is not the default.

It can be helpful when creating a new branch to use the existing
tracking configuration from the branch point. However, there is
currently not a method to automatically do so.
Teach git-{branch,checkout,switch} an "inherit" argument to the
"--track" option. When this is set, creating a new branch will cause the
tracking configuration to default to the configuration of the branch
point, if set.
For example, if branch "main" tracks "origin/main", and we run
`git checkout --track=inherit -b feature main`, then branch "feature"
will track "origin/main". Thus, `git status` will show us how far
ahead/behind we are from origin, and `git pull` will pull from origin.
This is particularly useful when creating branches across many
submodules, such as with `git submodule foreach ...` (or if running with
a patch such as [1], which we use at $job), as it avoids having to
manually set tracking info for each submodule.
Since we've added an argument to "--track", also add "--track=direct" as
another way to explicitly get the original "--track" behavior ("--track"
without an argument still works as well).
Finally, teach branch.autoSetupMerge a new "inherit" option. When this
is set, "--track=inherit" becomes the default behavior.

When a series of patches for a topic-B depends on having topic-A,
the workflow to prepare the topic-B branch would look like this:
$ git checkout -b topic-B main
$ git merge --no-ff --no-edit topic-A
$ git am <mbox-for-topic-B
When topic-A gets updated, recreating the first merge and rebasing
the rest of the topic-B, all on detached HEAD, is a useful
technique. After updating topic-A with its new round of patches:
$ git checkout topic-B
$ prev=$(git rev-parse 'HEAD^{/^Merge branch .topic-A. into}')
$ git checkout --detach $prev^1
$ git merge --no-ff --no-edit topic-A
$ git rebase --onto HEAD $prev @{-1}^0
$ git checkout -B @{-1}
This will
(0) check out the current topic-B.
(1) find the previous merge of topic-A into topic-B.
(2) detach the HEAD to the parent of the previous merge.
(3) merge the updated topic-A to it.
(4) reapply the patches to rebuild the rest of topic-B.
(5) update topic-B with the result.
without contaminating the reflog of topic-B too much. topic-B@{1}
is the "logically previous" state before topic-A got updated, for
example. At (4), comparison (e.g. range-diff) between HEAD and
@{-1} is a meaningful way to sanity check the result, and the same
can be done at (5) by comparing topic-B and topic-B@{1}.
But there is one glitch. The merge into the detached HEAD done in
the step (3) above gives us "Merge branch 'topic-A' into HEAD", and
does not say "into topic-B".
Teach the "--into-name=<branch>" option to "git merge" and its
underlying "git fmt-merge-message", to pretend as if we were merging
into <branch>, no matter what branch we are actually merging into,
when they prepare the merge message. The pretend name honors the
usual "into <target>" suppression mechanism, which can be seen in
the tests added here.

The git-p4 script reports file sizes in various log messages.
Previously, in each case the script would print them as the number of
bytes divided by 1048576 i.e. the size in mebibytes, rounded down to an

format_size_human_readable, which takes a number of bytes (or any other
quantity), and computes the appropriate prefix to use: none, Ki, Mi, Gi,
Ti, Pi, Ei, Zi, Yi.

Certain invocations of "git apply --3way" will attempt threeway and
fail due to missing objects, even though git is able to fall back on
apply_fragments and apply the patch successfully with a return value
of 0. To fix, return early from try_threeway() in the following
cases:
- When the patch is a rename and no lines have changed. In this
case, "git diff" doesn't record the blob info, so 3way is neither
possible nor necessary.
- When the patch is an addition and there is no add/add conflict,
i.e. direct_to_threeway is false. In this case, threeway will
fail since the preimage is not in cache, but isn't necessary
anyway since there is no conflict.

While testing some ideas in 'git repack', I ran it with '--quiet' and
discovered that some progress output was still shown. Specifically, the
output for writing the multi-pack-index showed the progress.
The 'show_progress' variable in cmd_repack() is initialized with
isatty(2) and is not modified at all by the '--quiet' flag. The
'--quiet' flag modifies the po_args.quiet option which is translated
into a '--quiet' flag for the 'git pack-objects' child process. However,
'show_progress' is used to directly send progress information to the
multi-pack-index writing logic which does not use a child process.
The fix here is to modify 'show_progress' to be false if po_opts.quiet
is true, and isatty(2) otherwise. This new expectation simplifies a
later condition that checks both.
Update the documentation to make it clear that '-q' will disable all
progress in addition to ensuring the 'git pack-objects' child process
will receive the flag.
Use 'test_terminal' to check that this works to get around the isatty(2)
check.

Historically, we needed a single packfile in order to have reachability
bitmaps. This introduced logic that when 'git repack' had a '-b' option
that we should stop sending the '--honor-pack-keep' option to the 'git
pack-objects' child process, ensuring that we create a packfile
containing all reachable objects.
In the world of multi-pack-index bitmaps, we no longer need to repack
all objects into a single pack to have valid bitmaps. Thus, we should
continue sending the '--honor-pack-keep' flag to 'git pack-objects'.
The fix is very simple: only disable the flag when writing bitmaps but
also _not_ writing the multi-pack-index.
This opens the door to new repacking strategies that might want to keep
some historical set of objects in a stable pack-file while only
repacking more recent objects.
To test, create a new 'test_subcommand_inexact' helper that is more
flexible than 'test_subcommand'. This allows us to look for the
--honor-pack-keep flag without over-indexing on the exact set of
arguments.

The option --invert-grep is documented to filter out commits whose

header matches (--author, --committer), which is not intended.
Move the handling of that option to grep.c, as only the code there can
distinguish between matches in the header from those in the message
body. If --invert-grep is given then enable extended expressions (not
the regex type, we just need git grep's --not to work), negate the body
patterns and check if any of them match by piggy-backing on the
collect_hits mechanism of grep_source_1().
Collecting the matches in struct grep_opt is a bit iffy, but with
"last_shown" we have a precedent for writing state information to that
struct.

RCS keywords are strings that are replaced with information from
Perforce. Examples include $Date$, $Author$, $File$, $Change$ etc.
Perforce resolves these by expanding them with their expanded values
when files are synced, but Git's data model requires these expanded
values to be converted back into their unexpanded form.
Previously, git-p4.py would implement this behaviour through the use of
regular expressions. However, the regular expression substitution was
applied using decoded strings i.e. the content of incoming commit diffs
was first decoded from bytes into UTF-8, processed with regular
expressions, then converted back to bytes.
Not only is this behaviour inefficient, but it is also a cause of a
common issue caused by text files containing invalid UTF-8 data. For
files created in Windows, CP1252 Smart Quote Characters (0x93 and 0x94)
are seen fairly frequently. These codes are invalid in UTF-8, so if the
script encountered any file containing them, on Python 2 the symbols
will be corrupted, and on Python 3 the script will fail with an
exception.
This patch replaces this decoding/encoding with bytes object regular
expressions, so that the substitution is performed directly upon the
source data with no conversions.
A test for smart quote handling has been added to the
t9810-git-p4-rcs.sh test suite.

That we emitted the usage for just "push" in the case of the
subcommand not being explicitly specified was an unintentional
side-effect of how it was implemented. When it was converted to C in
d553f538b8 (stash: convert push to builtin, 2019-02-25) the pattern
of having per-subcommand usage information was rightly continued. The
"git-stash.sh" shellscript did not have that, and always printed the
equivalent of "git_stash_usage".
But in doing so the case of push being implicit and explicit was
conflated. A variable was added to track this in 8c3713cede (stash:
eliminate crude option parsing, 2020-02-17), but it did not update the
usage output accordingly.
This still leaves e.g. "git stash push -h" emitting the
"git_stash_usage" output, instead of "git_stash_push_usage". That
should be fixed, but is a much deeper misbehavior in parse_options()
not being aware of subcommands at all. I.e. in how
PARSE_OPT_KEEP_UNKNOWN and PARSE_OPT_NO_INTERNAL_HELP combine in
commands such as "git stash".
Perhaps PARSE_OPT_KEEP_UNKNOWN should imply
PARSE_OPT_NO_INTERNAL_HELP, or better yet parse_options() should be
extended to fully handle these subcommand cases that we handle
manually in "git stash", "git commit-graph", "git multi-pack-index"
etc. All of those musings would be a much bigger change than this
isolated fix though, so let's leave that for some other time.

cache writes requires 8 pipe reads and 8 pipe writes from
git-upload-pack, and 8 pipe reads from Gitaly (our Git RPC service).
If we increase the size of the buffer to the maximum Git packet size,
we need only 1 pipe read and 1 pipe write in git-upload-pack, and 1
pipe read in Gitaly to transfer the same amount of data. In benchmarks
with a pure fetch and 100% cache hit rate workload we are seeing CPU
utilization reductions of over 30%.

The previous commits marked `sparse-checkout init` as deprecated; we
can just use `set` instead here and pass it no paths.

As noted in the previous commit, using separate `init` and `set` steps
with sparse-checkout result in a number of issues. The previous commits
made `set` able to handle the work of both commands, and enabled reapply
to tweak the {cone,sparse-index} settings. Update the documentation to
reflect this, and mark `init` as deprecated.

Folks may want to switch to or from cone mode, or to or from a
sparse-index without changing their sparsity paths. Allow them to do so
using the reapply command.

The previously suggested workflow:
git sparse-checkout init ...
git sparse-checkout set ...
Suffered from three problems:
1) It would delete nearly all files in the first step, then
restore them in the second. That was poor performance and
forced unnecessary rebuilds.
2) The two-step process resulted in two progress bars, which
was suboptimal from a UI point of view for wrappers that
invoked both of these commands but only exposed a single
command to their end users.
3) With cone mode, the first step would delete nearly all
ignored files everywhere, because everything was considered
to be outside of the specified sparsity paths. (The user was
not allowed to specify any sparsity paths in the `init` step.)
Avoid these problems by teaching `set` to understand the extra
parameters that `init` takes and performing any necessary initialization
if not already in a sparse checkout.

`init` has some code for handling updates to either cone mode or
the sparse-index setting. We would like to be able to reuse this
elsewhere, namely in `set` and `reapply`. Split this function out,
and make it slightly more general so it can handle being called from
the new callers.

We intentionally added --stdin as an option to `sparse-checkout set`,
but didn't intend for --no-stdin to be permitted as well.
