packfile: actually set approximate_object_count_valid

(find_unique_abbrev: move logic out of get_short_sha1(), 2016-10-03), we
failed to actually set the "valid" flag, meaning we'd compute it fresh
on every call.
This turns out not to be _too_ bad, because we're only iterating through
the packed_git list, and not making any system calls. But since it may
get called for every abbreviated hash we output, even this can add up if
you have many packs.
Here are before-and-after timings for a new perf test which just asks
rev-list to abbreviate each commit hash (the test repo is linux.git,
with commit-graphs):
Test origin HEAD
----------------------------------------------------------------------------
5303.3: rev-list (1) 28.91(28.46+0.44) 29.03(28.65+0.38) +0.4%
5303.4: abbrev-commit (1) 1.18(1.06+0.11) 1.17(1.02+0.14) -0.8%
5303.7: rev-list (50) 28.95(28.56+0.38) 29.50(29.17+0.32) +1.9%

5303.15: load 10,000 packs 0.08(0.02+0.05) 0.08(0.02+0.06) +0.0%
It doesn't help at all when we have 1 pack (5303.4), but we get a 10%
speedup when there are 1000 packs (5303.12). That's a modest speedup for
a case that's already slow and we'd hope to avoid in general (note how
slow it is even after, because we have to look in each of those packs
for abbreviations). But it's a one-line change that clearly matches the
original intent, so it seems worth doing.
The included perf test may also be useful for keeping an eye on any
regressions in the overall abbreviation code.

Instead of writing a new commit-graph in every 'git maintenance run

commit-graph file.
This count is controlled by the maintenance.commit-graph.auto config

To compute the count, use a depth-first search starting at each ref, and
leaving markers using the SEEN flag. If this count reaches the limit,
then terminate early and start the task. Otherwise, this operation will
peel every ref and parse the commit it points to. If these are all in
the commit-graph, then this is typically a very fast operation. Users
with many refs might feel a slow-down, and hence could consider updating
their limit to be very small. A negative value will force the step to

maintenance: use pointers to check --auto
The 'git maintenance run' command has an '--auto' option. This is used
by other Git commands such as 'git commit' or 'git fetch' to check if
maintenance should be run after adding data to the repository.
Previously, this --auto option was only used to add the argument to the
'git gc' command as part of the 'gc' task. We will be expanding the
other tasks to perform a check to see if they should do work as part of
the --auto flag, when they are enabled by config.
First, update the 'gc' task to perform the auto check inside the
maintenance process. This prevents running an extra 'git gc --auto'
command when not needed. It also shows a model for other tasks.
Second, use the 'auto_condition' function pointer as a signal for
whether we enable the maintenance task under '--auto'. For instance, we
do not want to enable the 'fetch' task in '--auto' mode, so that
function pointer will remain NULL.
Now that we are not automatically calling 'git gc', a test in
t5514-fetch-multiple.sh must be changed to watch for 'git maintenance'
instead.
We continue to pass the '--auto' option to the 'git gc' command when
necessary, because of the gc.autoDetach config option changes behavior.
Likely, we will want to absorb the daemonizing behavior implied by
gc.autoDetach as a maintenance.autoDetach config option.

maintenance: take a lock on the objects directory
Performing maintenance on a Git repository involves writing data to the
.git directory, which is not safe to do with multiple writers attempting
the same operation. Ensure that only one 'git maintenance' process is
running at a time by holding a file-based lock. Simply the presence of
the .git/maintenance.lock file will prevent future maintenance. This
lock is never committed, since it does not represent meaningful data.
Instead, it is only a placeholder.
If the lock file already exists, then no maintenance tasks are
attempted. This will become very important later when we implement the

Here is where our array of maintenance_task pointers becomes critical.
We can sort the array of pointers based on the task order, but we do not
want to move the struct data itself in order to preserve the hashmap
references. We use the hashmap to match the --task=<task> arguments into
the task struct data.
Keep in mind that the 'enabled' member of the maintenance_task struct is
a placeholder for a future 'maintenance.<task>.enabled' config option.
Thus, we use the 'enabled' member to specify which tasks are run when
the user does not specify any --task=<task> arguments. The 'enabled'

maintenance: add commit-graph task
The first new task in the 'git maintenance' builtin is the
'commit-graph' task. This updates the commit-graph file
incrementally with the command
git commit-graph write --reachable --split
By writing an incremental commit-graph file using the "--split"
option we minimize the disruption from this operation. The default
behavior is to merge layers until the new "top" layer is less than
half the size of the layer below. This provides quick writes most
of the time, with the longer writes following a power law
distribution.
Most importantly, concurrent Git processes only look at the
commit-graph-chain file for a very short amount of time, so they
will verly likely not be holding a handle to the file when we try
to replace it. (This only matters on Windows.)
If a concurrent process reads the old commit-graph-chain file, but

maintenance: initialize task array
In anticipation of implementing multiple maintenance tasks inside the
'maintenance' builtin, use a list of structs to describe the work to be
done.
The struct maintenance_task stores the name of the task (as given by a
future command-line argument) along with a function pointer to its
implementation and a boolean for whether the step is enabled.
A list these structs are initialized with the full list of implemented
tasks along with a default order. For now, this list only contains the
"gc" task. This task is also the only task enabled by default.
The run subcommand will return a nonzero exit code if any task fails.
However, it will attempt all tasks in its loop before returning with the
failure. Also each failed task will print an error message.

maintenance: replace run_auto_gc()
The run_auto_gc() method is used in several places to trigger a check
for repo maintenance after some Git commands, such as 'git commit' or
'git fetch'.
To allow for extra customization of this maintenance activity, replace
the 'git gc --auto [--quiet]' call with one to 'git maintenance run
--auto [--quiet]'. As we extend the maintenance builtin with other
steps, users will be able to select different maintenance activities.
Rename run_auto_gc() to run_auto_maintenance() to be clearer what is
happening on this call, and to expose all callers in the current diff.
Rewrite the method to use a struct child_process to simplify the calls
slightly.
Since 'git fetch' already allows disabling the 'git gc --auto'
subprocess, add an equivalent option with a different name to be more
descriptive of the new behavior: '--[no-]maintenance'. Update the
documentation to include these options at the same time.

maintenance: create basic maintenance runner
The 'gc' builtin is our current entrypoint for automatically maintaining
a repository. This one tool does many operations, such as repacking the
repository, packing refs, and rewriting the commit-graph file. The name
implies it performs "garbage collection" which means several different
things, and some users may not want to use this operation that rewrites
the entire object database.
Create a new 'maintenance' builtin that will become a more general-
purpose command. To start, it will only support the 'run' subcommand,
but will later expand to add subcommands for scheduling maintenance in
the background.
For now, the 'maintenance' builtin is a thin shim over the 'gc' builtin.
In fact, the only option is the '--auto' toggle, which is handed
directly to the 'gc' builtin. The current change is isolated to this
simple operation to prevent more interesting logic from being lost in
all of the boilerplate of adding a new builtin.
Use existing builtin/gc.c file because we want to share code between the
two builtins. It is possible that we will have 'maintenance' replace the
'gc' builtin entirely at some point, leaving 'git gc' as an alias for
some specific arguments to 'git maintenance run'.
Create a new test_subcommand helper that allows us to test if a certain
subcommand was run. It requires storing the GIT_TRACE2_EVENT logs in a
file. A negation mode is available that will be used in later tests.

there was, the result is quoted already so it is OK, too.
(2) if the input string did not get escaped, and the result has SP

Instead we can scan the path upfront to see if the input has SP in

input had bytes that quote_c_style_counted() uses backslash quoting,

intent-to-add paths are now show as new files rather than changes to

implement patch editing correctly. The perl version simply forbade
editing and the C version opened the editor with the full diff rather
that just the hunk which meant that the user had to edit the hunk
header manually to get it to work.
The root cause of the problem is that added files store the diff header
with the hunk data rather than separating the two as we do for other
changes. Changing added files to store the diff header separately
fixes the editing problem at the expense of having to special case
empty additions as they no longer have any hunks associated with them,

index-pack: make quantum of work smaller
Currently, when index-pack resolves deltas, it does not split up delta
trees into threads: each delta base root (an object that is not a
REF_DELTA or OFS_DELTA) can go into its own thread, but all deltas on
that root (direct or indirect) are processed in the same thread.
This is a problem when a repository contains a large text file (thus,
delta-able) that is modified many times - delta resolution time during
fetching is dominated by processing the deltas corresponding to that
text file.
This patch contains a solution to that. When cloning using
git -c core.deltabasecachelimit=1g clone \
https://fuchsia.googlesource.com/third_party/vulkan-cts
on my laptop, clone time improved from 3m2s to 2m5s (using 3 threads,
which is the default).
The solution is to have a global work stack. This stack contains delta
bases (objects, whether appearing directly in the packfile or generated
by delta resolution, that themselves have delta children) that need to
be processed; whenever a thread needs work, it peeks at the top of the
stack and processes its next unprocessed child. If a thread finds the
stack empty, it will look for more delta base roots to push on the stack
instead.
The main weakness of having a global work stack is that more time is
spent in the mutex, but profiling has shown that most time is spent in
the resolution of the deltas themselves, so this shouldn't be an issue
in practice. In any case, experimentation (as described in the clone
command above) shows that this patch is a net improvement.

referencing HEAD to fail. Avoid this side-effect by switching back to
master after the test finishes.
This has gone undetected, as the next affected test expects failure -
but it currently fails for the wrong reason.
Verbose output of the next test referencing HEAD,
"--merged is incompatible with --no-merged":
fatal: malformed object name HEAD
Which this commit corrects to:
error: option `no-merged' is incompatible with --merged

format-patch: use 'origin' as start of current-series-range when known
When formatting a patch series over `origin..HEAD`, one would expect
that range to be used as the current-series-range when computing a
range-diff between the previous and current versions of a patch series.
However, infer_range_diff_ranges() ignores `origin..HEAD` when
--range-diff=<prev> specifies a single revision rather than a range, and
instead unexpectedly computes the current-series-range based upon
<prev>. Address this anomaly by unconditionally using `origin..HEAD` as
the current-series-range regardless of <prev> as long as `origin` is
known, and only fall back to basing current-series-range on <prev> when
`origin` is not known.

diff-lib: tighten show_interdiff()'s interface
To compute and show an interdiff, show_interdiff() needs only the two
OID's to compare and a diffopts, yet it expects callers to supply an
entire rev_info. The demand for rev_info is not only overkill, but also
places unnecessary burden on potential future callers which might not
otherwise have a rev_info at hand. Address this by tightening its
signature to require only the items it needs instead of a full rev_info.

diff: move show_interdiff() from its own file to diff-lib
show_interdiff() is a relatively small function and not likely to grow

compare them" functions meant to be re-used but not so low-level as to

add -i: use the built-in version when feature.experimental is set
We have had parallel implementations of "add -i/-p" since 2.25 and

We have found and fixed a handful of corner case bugs in the

add--interactive.perl: specify --no-color explicitly
Our color tests of "git add -p" do something a bit different from how a
normal user would behave: we pretend there's a pager in use, so that Git
thinks it's OK to write color to a non-tty stdout. This comes from
8539b46534 (t3701: avoid depending on the TTY prerequisite, 2019-12-06),
which allows us to avoid a lot of complicated mock-tty code.
However, those environment variables also make their way down to
sub-processes of add--interactive, including the "diff-files" we run to
generate the patches. As a result, it thinks it should output color,
too. So in t3701.50, for example, the machine-readable version of the
diff we get unexpectedly has color in it. We fail to parse it as a diff
and think there are zero hunks.
The test does still pass, though, because even with zero hunks we'll
dump the diff header (and we consider those unparseable bits to be part
of the header!), and so the output still has the expected color codes in
it. We don't notice that the command was totally broken and failed to
apply anything.
And in fact we're not really testing what we think we are about the
color, either. While add--interactive does correctly show the version we
got from running "diff-files --color", we'd also pass the test if we had
accidentally shown the machine-readable version, too, since it
(erroneously) has color codes in it.
One could argue that the test isn't very realistic; it's setting up this
"pretend there's a pager" situation to get around the tty restrictions
of the test environment. So one option would be to move back towards
using a real tty. But the behavior of add--interactive really is
user-visible here. If a user, for whatever reason, did run "git
--paginate add --patch" (perhaps because their pager is really a filter
or something), the command would totally fail to do anything useful.
Since we know that we don't want color in this output, let's just make
add--interactive more defensive, and say "--no-color" explicitly. It
doesn't hurt anything in the common case, but it fixes this odd case and
lets our test function properly again.
Note that the C builtin run_add_p() already passes --no-color, so it
doesn't need a similar fix. That will eventually replace this perl code
anyway, but the test change here will be valuable for ensuring that.

add-patch: fix inverted return code of repo_read_index()
After applying hunks to a file with "add -p", the C patch_update_file()
function tries to refresh the index (just like the perl version does).
We can only refresh the index if we're able to read it in, so we first
check the return value of repo_read_index(). But unlike many functions,
where "0" is success, that function is documented to return the number
of entries in the index. Hence we should be checking for success with a
non-negative return value.
Neither the tests nor any users seem to have noticed this, probably due
to a combination of:
- this affects only the C version, which is not yet the default
- following it up with any porcelain command like "git diff" or "git
commit" would refresh the index automatically.
But you can see the problem by running the plumbing "git diff-files"
immediately after "add -p" stages all hunks. Running the new test with
GIT_TEST_ADD_I_USE_BUILTIN=1 fails without the matching code change.

git-worktree.txt: discuss branch-based vs. throwaway worktrees
By default, `git worktree add` creates a new worktree associated with a
particular branch (which may have been created automatically if not
specified explicitly on the command-line). It is also convenient to
create throwaway worktrees not associated with any branch, which can be
handy when making experimental changes or doing testing. However, the
latter use-case may not be obvious to newcomers since the high-level
description of worktrees talks only about checking out "more than one
branch at a time". Therefore, enhance the description to to discuss both
use-cases.
A secondary goal of highlighting the distinction between branch-based
and throwaway worktrees is to help newcomers understand that the
simplest form `git worktree add <path>` automatically creates a new
branch. Stating this early in the description, may help newcomers avoid
creating branches without realizing they are doing so, and later
wondering why `git branch --list` shows branches the user did not
intentionally create.
