4de656263a upload-pack: look up "want" lines via commit-graph
During packfile negotiation the client will send "want" and "want-ref"
lines to the server to tell it which objects it is interested in. The
server-side parses each of those and looks them up to see whether it
actually has requested objects. This lookup is performed by calling
`parse_object()` directly, which thus hits the object database. In the
general case though most of the objects the client requests will be
commits. We can thus try to look up the object via the commit-graph
opportunistically, which is much faster than doing the same via the
object database.

Refactor parsing of both "want" and "want-ref" lines to do so.

The following benchmark is executed in a repository with a huge number
of references. It uses cached request from git-fetch(1) as input to
git-upload-pack(1) that contains about 876,000 "want" lines:

    Benchmark 1: HEAD~
      Time (mean ± σ):      7.113 s ±  0.028 s    [User: 6.900 s, System: 0.662 s]
      Range (min … max):    7.072 s …  7.168 s    10 runs

    Benchmark 2: HEAD
      Time (mean ± σ):      6.622 s ±  0.061 s    [User: 6.452 s, System: 0.650 s]
      Range (min … max):    6.535 s …  6.727 s    10 runs

    Summary
      'HEAD' ran
        1.07 ± 0.01 times faster than 'HEAD~'

71f26798f2 test-lib: add "fast_unwind_on_malloc=0" to LSAN_OPTIONS
Add "fast_unwind_on_malloc=0" to LSAN_OPTIONS to get more meaningful
stack traces from LSAN. This isn't required under ASAN which will emit
traces such as this one for a leak in "t/t0006-date.sh":

    $ ASAN_OPTIONS=detect_leaks=1 ./t0006-date.sh -vixd

    SUMMARY: AddressSanitizer: 3 byte(s) leaked in 1 allocation(s).

Whereas LSAN would emit this instead:

    [...]
    Direct leak of 3 byte(s) in 1 object(s) allocated from:
        #0 0x4323b8 in malloc (t/helper/test-tool+0x4323b8)

    SUMMARY: LeakSanitizer: 3 byte(s) leaked in 1 allocation(s).

Now we'll instead git this sensible stack trace under
LSAN. I.e. almost the same one (but starting with "malloc", as is
usual for LSAN) as under ASAN:

    Direct leak of 3 byte(s) in 1 object(s) allocated from:

    SUMMARY: LeakSanitizer: 3 byte(s) leaked in 1 allocation(s).

As the option name suggests this does make things slower, e.g. for
t0001-init.sh we're around 10% slower:

    $ hyperfine -L v 0,1 'LSAN_OPTIONS=fast_unwind_on_malloc={v} make T=t0001-init.sh' -r 3
    Benchmark 1: LSAN_OPTIONS=fast_unwind_on_malloc=0 make T=t0001-init.sh
      Time (mean ± σ):      2.135 s ±  0.015 s    [User: 1.951 s, System: 0.554 s]
      Range (min … max):    2.122 s …  2.152 s    3 runs

    Benchmark 2: LSAN_OPTIONS=fast_unwind_on_malloc=1 make T=t0001-init.sh
      Time (mean ± σ):      1.981 s ±  0.055 s    [User: 1.769 s, System: 0.488 s]
      Range (min … max):    1.941 s …  2.044 s    3 runs

    Summary
      'LSAN_OPTIONS=fast_unwind_on_malloc=1 make T=t0001-init.sh' ran
        1.08 ± 0.03 times faster than 'LSAN_OPTIONS=fast_unwind_on_malloc=0 make T=t0001-init.sh'

I think that's more than worth it to get the more meaningful stack
traces, we can always provide LSAN_OPTIONS=fast_unwind_on_malloc=0 for
one-off "fast" runs.

b9638d7286 test-lib: make $GIT_BUILD_DIR an absolute path
Change the GIT_BUILD_DIR from a path like "/path/to/build/t/.." to
"/path/to/build". The "TEST_DIRECTORY" here is already made an
absolute path a few lines above this.

We could simply do $(cd "$TEST_DIRECTORY"/.." && pwd) here, but as
noted in the preceding commit the "$TEST_DIRECTORY" can't be anything
except the path containing this test-lib.sh file at this point, so we
can more cheaply and equally strip the "/t" off the end.

This change will be helpful to LSAN_OPTIONS which will want to strip
the build directory path from filenames, which we couldn't do if we
had a "/.." in there.

9dbf20e7f6 test-lib: correct and assert TEST_DIRECTORY overriding
Correct a misleading comment added by me in 62f539043c (test-lib:
Allow overriding of TEST_DIRECTORY, 2010-08-19), and add an assertion
that TEST_DIRECTORY cannot point to any directory except the "t"
directory in the top-level of git.git.

This assertion is in effect not new, since we'd already die if that
wasn't the case[1], but it and the updated commentary help to make
that clearer.

The existing comments were also on the wrong arms of the
"if". I.e. the "allow tests to override this" was on the "test -z"
arm. That came about due to a combination of 62f539043c and
85176d7251 (test-lib.sh: convert $TEST_DIRECTORY to an absolute path,
2013-11-17).

Those earlier comments could be read as allowing the "$TEST_DIRECTORY"
to be some path outside of t/. As explained in the updated comment
that's impossible, rather it was meant for *tests* that ran outside of
t/, i.e. the "t0000-basic.sh" tests that use "lib-subtest.sh".

Those tests have a different working directory, but they set the
"TEST_DIRECTORY" to the same path for bootstrapping. The comments now
reflect that, and further comment on why we have a hard dependency on
this.

66c1a56870 test-lib: add GIT_SAN_OPTIONS, inherit [AL]SAN_OPTIONS
Change our ASAN_OPTIONS and LSAN_OPTIONS to set defaults for those
variables, rather than punting out entirely if we already have them in
the environment.

We want to take any user-provided settings over our own, but we can do
that by prepending our defaults to the variable. The libsanitizer
options parsing has "last option wins" semantics.

It's now possible to do e.g.:

    LSAN_OPTIONS=report_objects=1 ./t0006-date.sh

And not have the "report_objects=1" setting overwrite our sensible
default of "abort_on_error=1", but by prepending to the list we ensure
that:

    LSAN_OPTIONS=report_objects=1:abort_on_error=0 ./t0006-date.sh

Will take the desired "abort_on_error=0" over our default.

See b0f4c9087e (t: support clang/gcc AddressSanitizer, 2014-12-08)
for the original pattern being altered here, and
85b81b35ff (test-lib: set LSAN_OPTIONS to abort by default,
2017-09-05) for when LSAN_OPTIONS was added in addition to the
then-existing ASAN_OPTIONS.

317956d912 untracked-cache: write index when populating empty untracked cache
It is expected that an empty/unpopulated untracked cache structure can
be written to the index - by update-index, or by a "git status" call
that sees the untracked cache should be enabled and is not, but is
running with options that make the untracked cache non-applicable in
that run (eg a pathspec).

Currently, if that happens, then subsequent "git status" calls end up
populating the untracked cache, but not writing the index (not saving
their work) - so the performance outcome is almost identical to the
cache being altogether disabled.

This continues until the index gets written with the untracked cache
populated, for some *other* reason, such as a working tree change.

Detect the condition where an empty untracked cache exists in the
index and we will collect the list of untracked paths, and queue an
index write under that condition, so that the collected untracked
paths can be written out to the untracked cache extension in the
index.

This change depends on previous fixes to t7519 for the "ignore .git
changes when invalidating UNTR" test case to pass - before this fix,
the test never actually did anything as it was not set up correctly.

37482b4080 t7519: populate untracked cache before test
In its current state, the t7519 test dealing with untracked cache
assumes that "git update-index --untracked-cache" will *populate* the
untracked cache. This is not correct - it will only add an empty
untracked cache structure to the index.

If we're going to compare two git status runs with something
interesting happening in-between, we need to ensure that the index is
in a stable/steady state *before* that first run.

Achieve this by adding another prior "git status" run.

At this stage this change does nothing, because there is a bug,
addressed in the next patch, whereby once the empty untracked cache
structure is added by the update-index invocation, the untracked cache
gets updated in every subsequent "git status" call, but the index with
these updates does not get written down.

That bug actually invalidates this entire test case - but we're fixing
that next.

a67d178be4 t7519: avoid file to index mtime race for untracked cache
In t7519 there is a test that writes files to disk, and immediately
writes the index with the untracked cache. Because of
mtime-comparison logic that uses a 1-second resolution, this means
the cached entries are not trusted/used under some circumstances
(see read-cache.c#is_racy_stat()).

Untracked cache tests in t7063 use a 1-second delay to avoid this
issue, but we don't want to introduce arbitrary slowdowns, so instead
use test-tool chmtime to backdate the files slightly. The t7063
delays are a #leftoverbit, to be worked on in a separate series.

This change doesn't actually affect the outcome of the test, but does
enhance its validity, and becomes relevant after later changes.

2587df669b rerere-train: two fixes to the use of "git show -s"
The script uses "git show -s" to display the title of the merge
commit being studied, without explicitly disabling the pager, which
is not a safe thing to do in a script.

For example, when the pager is set to "less" with "-SF" options (-S
tells the pager not to fold lines but allow horizontal scrolling to
show the overly long lines, -F tells the pager not to wait if the
output in its entirety is shown on a single page), and the title of
the merge commit is longer than the width of the terminal, the pager
will wait until the end-user tells it to quit after showing the
single line.

Explicitly disable the pager with this "git show" invocation to fix
this.

The command uses the "--pretty=format:..." format, which adds LF in
between each pair of commits it outputs, which means that the label
for the merge being learned from will be followed by the next
message on the same line.  "--pretty=tformat:..." is what we should
instead, which adds LF after each commit, or a more modern way to
spell it, i.e. "--format=...".  This existing breakage becomes
easier to see, now we no longer use the pager.

instead of "tree_type".

The "cat-file" caller is not on the codepath that
handles"--allow-unknown", so the type_from_string() there is safe. Its
use of type_from_string() doesn't functionally differ from that of the
pre-image.

0ff7b4f976 object API: rename hash_object_file_literally() to write_*()
Before 0c3db67cc8 (hash-object --literally: fix buffer overrun with

here called write_sha1_file() to both hash and write a loose
object. Before that we'd use hash_sha1_file() to if "-w" wasn't
provided, and otherwise call write_sha1_file().

Now we'll always call the same function for both writing. Let's rename
it from hash_*_literally() to write_*_literally(). Even though the
write_*() might not actually write if HASH_WRITE_OBJECT isn't in
"flags", having it be more similar to write_object_file_flags() than
hash_object_file(), but carrying a name that would suggest that it's a
variant of the latter is confusing.

0f156dbb04 object-file API: split up and simplify check_object_signature()
Split up the check_object_signature() function into that non-streaming
version (it accepts an already filled "buf"), and a new
stream_object_signature() which will retrieve the object from storage,
and hash it on-the-fly.

All of the callers of check_object_signature() were effectively
calling two different functions, if we go by cyclomatic
complexity. I.e. they'd either take the early "if (map)" branch and
return early, or not. This has been the case since the "if (map)"
condition was added in 090ea12671 (parse_object: avoid putting whole
blob in core, 2012-03-07).

We can then further simplify the resulting check_object_signature()
function since only one caller wanted to pass a non-NULL "buf" and a
non-NULL "real_oidp". That "read_loose_object()" codepath used by "git
fsck" can instead use hash_object_file() followed by oideq().

This avoids the back & forth fragility where the callers of

themselves via type_name(). We do have to now do that conversion
ourselves before calling write_object_file_prepare(), but those
codepaths will be similarly adjusted in subsequent commits.

b04cdea46c object-file API: add a format_object_header() function
Add a convenience function to wrap the xsnprintf() command that
generates loose object headers. This code was copy/pasted in various
parts of the codebase, let's define it in one place and re-use it from
there.

All except one caller of it had a valid "enum object_type" for us,
it's only write_object_file_prepare() which might need to deal with
"git hash-object --literally" and a potential garbage type. Let's have
the primary API use an "enum object_type", and define a *_literally()
function that can take an arbitrary "const char *" for the type.

See [1] for the discussion that prompted this patch, i.e. new code in
object-file.c that wanted to copy/paste the xsnprintf() invocation.

In the case of fast-import.c the callers unfortunately need to cast
back & forth between "unsigned char *" and "char *", since
format_object_header() ad encode_in_pack_object_header() take
different signedness.

bbea0ddeb9 object-file.c: split up declaration of unrelated variables
Split up the declaration of the "ret" and "re_allocated"
variables. It's not our usual style to group variable declarations
simply because they share a type, we'd only prefer to do so when the
two are closely related (e.g. "int i, j"). This change makes a
subsequent and meaningful change's diff smaller.

Change the "struct userdiff_driver" assignmentns to use designated

macros to avoid churn, but have them defined in terms of designated

For the "driver_true" and "driver_false" let's have the compiler
implicitly initialize most of the fields, but let's leave a redundant
".binary = 0" for "driver_true" to make it obvious that it's the
opposite of the the ".binary = 1" for "driver_false".

ceaf037f61 stash: strip "refs/heads/" with skip_prefix
When generating a message for a stash, "git stash" only records the
part of the branch name to the right of the last "/". e.g. if HEAD is at
"foo/bar/baz", "git stash" generates a message prefixed with "WIP on
baz:" instead of "WIP on foo/bar/baz:".

Fix this by using skip_prefix() to skip "refs/heads/" instead of looking
for the last instance of "/".

the user is unlikely to have configured the limit (their host did).
Also demonstrate the human-readable message in a test.
