c5c3486f38 transport-helper: recognize "expecting report" error from send-pack
When a transport helper pushes via send-pack, it passes --helper-status
to get a machine-readable status back for each ref. The previous commit
taught the send-pack code to hand back "error expecting report" if the
server did not send us the proper ref-status. And that's enough to cause
us to recognize that an error occurred for the ref and print something
sensible in our final status table.

But we do interpret these messages on the remote-helper side to turn
them back into REF_STATUS_* enum values.  Recognizing this token to turn
it back into REF_STATUS_EXPECTING_REPORT has two advantages:

  1. We now print exactly the same message in the human-readable (and
     machine-readable --porcelain) output for this situation whether the
     transport went through a helper (e.g., http) or not (e.g., ssh).

  2. If any code in the helper really cares about distinguishing
     EXPECT_REPORT from more generic error conditions, it could now do
     so. I didn't find any, so this is mostly future-proofing.

So this is mostly cosmetic for now, but it seems like the
least-surprising thing for the transport-helper code to be doing.

e4c9538a9c send-pack: complain about "expecting report" with --helper-status
When pushing to a server which erroneously omits the final ref-status
report, the client side should complain about the refs for which we
didn't receive the status (because we can't just assume they were
updated). This works over most transports like ssh, but for http we'll
print a very misleading "Everything up-to-date".

It works for ssh because send-pack internally sets the status of each
ref to REF_STATUS_EXPECTING_REPORT, and then if the server doesn't tell
us about a particular ref, it will stay at that value. When we print the
final status table, we'll see that we're still on EXPECTING_REPORT and
complain then.

But for http, we go through remote-curl, which invokes send-pack with
"--stateless-rpc --helper-status". The latter option causes send-pack to
return a machine-readable list of ref statuses to the remote helper. But
ever since its inception in de1a2fdd38 (Smart push over HTTP: client
side, 2009-10-30), the send-pack code has simply omitted mention of any
ref which ended up in EXPECTING_REPORT.

In the remote helper, we then take the absence of any status report
from send-pack to mean that the ref was not even something we tried to
send, and thus it prints "Everything up-to-date". Fortunately it does
detect the eventual non-zero exit from send-pack, and propagates that in
its own non-zero exit code. So at least a careful script invoking "git
push" would notice the failure.  But sending the misleading message on
stderr is certainly confusing for humans (not to mention the
machine-readable "push --porcelain" output, though again, any careful
script should be checking the exit code from push, too).

Nobody seems to have noticed because the server in this instance has to
be misbehaving: it has promised to support the ref-status capability
(otherwise the client will not set EXPECTING_REPORT at all), but didn't
send us any. If the connection were simply cut, then send-pack would
complain about getting EOF while trying to read the status. But if the
server actually sends a flush packet (i.e., saying "now you have all of
the ref statuses" without actually sending any), then the client ends up
in this confused situation.

The fix is simple: we should return an error message from "send-pack
--helper-status", just like we would for any other error per-ref error
condition (in the test I included, the server simply omits all ref
status responses, but a more insidious version of this would skip only
some of them).

5e311edfd3 t1092: run "rebase --apply" without "-q" in testing
We run a few operations and make sure they produce identical results
with and without sparse-index; the version we merged to the "next"
branch used the "-q" option to work around a breakage caused by a
version used at Microsoft with some unreleased changes, but since
we would want to make sure the commands produce identical results,
including reports given to the output that lists which commits were
picked, use of "-q" loses too much interesting information.

Let's drop "-q" from the command invocation and revisit the issue
when the problematic changes are upstreamed.

a897ab7ed1 gc: perform incremental repack when implictly enabled
builtin/gc.c has two ways of checking if multi-pack-index is enabled:
- git_config_get_bool() in incremental_repack_auto_condition()
- the_repository->settings.core_multi_pack_index in
  maintenance_task_incremental_repack()

The two implementations have existed since the incremental-repack task
was introduced in e841a79a13 (maintenance: add incremental-repack auto
condition, 2020-09-25). These two values can diverge because
prepare_repo_settings() enables the feature in the_repository->settings
by default.

In the case where core.multiPackIndex is not set in the config, the auto
condition would fail, causing the incremental-repack task to not be
run. Because we always want to consider the default values, we should
always use the_repository->settings.

Standardize on using the_repository->settings.core_multi_pack_index to
check if multi-pack-index is enabled.

f30e4d854b fsck: verify commit graph when implicitly enabled
Change fsck to check the "core_commit_graph" variable set in

Add tests to "t5318-commit-graph.sh" to verify that fsck checks the
commit-graph as expected for the 3 values of core.commitGraph. Also,
disable GIT_TEST_COMMIT_GRAPH in t/t0410-partial-clone.sh because some

1c720357ce tests: stop using top-level "README" and "COPYING" files
In 459b8d22e5 (tests: do not borrow from COPYING and README from the
real source, 2015-02-15) tests that used "lib-diff.sh" (called
"diff-lib.sh" then) were made to stop relying on the top-level COPYING
file, but we still had other tests that referenced it.

Let's move them over to use the "COPYING_test_data" utility function
introduced in the preceding commit, and in the case of the one test
that needed the "README" file use a ROT 13 version of that "COPYING"
test data. That test added in afd222967c (Extend testing git-mv for
renaming of subdirectories, 2006-07-26) just needs more test data that's not the same as the "COPYING" test data, so a ROT 13 version will do.

This change removes the last references to ../{README,COPYING} in the
test suite.

15b808da74 "lib-diff" tests: make "README" and "COPYING" test data smaller
Follow-up the change in 459b8d22e5 (tests: do not borrow from COPYING
and README from the real source, 2015-02-15) by not shipping a full
copy of older versions of the top-level "COPYING" and "README" files.

The tests that use them just need the small blurb at the top of
"COPYING" as test data, or mock data that's dissimilar. Let's provide
that with a "COPYING_test_data" function instead.

We're not replacing this with some other generic test
data (e.g. "lorum ipsum") because these tests require test file header
to be the old "COPYING" file. See e.g. "t4003-diff-rename-1.sh" which
changes the file, and then does full "test_cmp" comparisons on the
resulting "git diff" output.

This change only changes tests that used the "lib-diff.sh" library,
but splits up what they need into a new "lib-diff-data.sh". A
subsequent commit will change related tests that were missed in
459b8d22e5.

For the test in "t4008-diff-break-rewrite.sh" the "README" file can go
away in favor of echoing the line "some dissimilar content" to a file
in the one test that needed it.

The point of that test is to start with files "A" and "B", and then
have A be more similar to the state of "B" than to its old version (by
copying over the content from the "COPYING" file). Just comparing the
pre-image of "some dissimilar content" and later a munged version of
the "COPYING" output serves that purpose.

While we're at it get rid of a stray "echo $tree" debugging line added
in 15d061b435 ([PATCH] Fix the way diffcore-rename records unremoved
source., 2005-05-27), and stop calling "hash-object" to get the hash
of an object we've just added to the index. We can instead extract
that information from the index itself with "rev-parse".

095d112f8c commit-graph: don't consider "replace" objects with "verify"
Extend the code added in d6538246d3 (commit-graph: not compatible
with replace objects, 2018-08-20) which ignored replace objects in the
"write" command to ignore it in the "verify" command too.

We can just move this assignment to the cmd_commit_graph(), it
dispatches to "write" and "verify", and we're unlikely to ever get a
sub-command that would like to consider replace refs.

This will make tests added in eddc1f556c (mktag tests: test
update-ref and reachable fsck, 2021-06-17) pass in combination with
the "GIT_TEST_COMMIT_GRAPH" mode added in 859fdc0c3c (commit-graph:
define GIT_TEST_COMMIT_GRAPH, 2018-08-29), except that mode is
currently broken (but is being fixed concurrently). See the discussion
starting at [1].

a046aa38ca commit-graph tests: fix another graph_git_two_modes() helper
In 135a712375 (commit-graph: add --split option to builtin,
2019-06-18) this function was copy/pasted to the split commit-graph
tests, as in the preceding commit we need to fix this to use
&&-chaining, so it won't be hiding errors.

Unlike its sister function in "t5318-commit-graph.sh", which we got
lucky with, this one was hiding a real test failure. A tests added in
c523035cbd (commit-graph: allow cross-alternate chains, 2019-06-18)
has never worked as intended. Unlike most other graph_git_behavior
uses in this file it clones the repository into a sub-directory, so
we'll need to refer to "commits/6" as "origin/commits/6".

It's not easy to simply move the "graph_git_behavior" to the test
above it, since it itself spawns a "test_expect_success". Let's
instead add support to "graph_git_behavior()" and
"graph_git_two_modes()" to pass a "-C" argument to git.

We also need to add a "test -d fork" here, because otherwise we'll
fail on e.g.:

    GIT_SKIP_TESTS=t5324.13 ./t5324-split-commit-graph.sh

The graph_git_two_modes() helper added in 177722b344 (commit:
integrate commit graph with commit parsing, 2018-04-10) didn't
&&-chain its "git commit-graph" invocations, which as can be seen with
SANITIZE=leak will happily mark tests as passing if both of these
commands die, since test_cmp() will be comparing two empty files.

5d22e18965 test-lib.sh: try to re-chmod & retry on failed trash removal
Try to re-chmod the trash directory on startup if we fail to "rm -rf"
it. This fixes problems where the test leaves the trash directory
behind in a bad permission state for whatever reason.

This fixes an interaction between [1] where t0004-unwritable.sh was
made to use "test_when_finished" for cleanup, and [2] which added the
"--immediate" mode. If a test in this file failed when running with
"--immediate" we wouldn't run the "test_when_finished" block, which
re-chmods the ".git/objects" directory (see [1]).

This can be demonstrated as e.g. (output snipped for less verbosity):

    $ ./t0004-unwritable.sh --run=3 --immediate
    ok 1 # skip setup (--run)
    ok 2 # skip write-tree should notice unwritable repository (--run)
    not ok 3 - commit should notice unwritable repository
    [...]
    $ ./t0004-unwritable.sh --run=3 --immediate
    rm: cannot remove '[...]/trash directory.t0004-unwritable/.git/objects/info': Permission denied
    FATAL: Cannot prepare test area
    [...]

Instead of some version of reverting [1] let's make the test-lib.sh
resilient to this edge-case, it will happen due to [1], but also
e.g. if the relevant "test-lib.sh" process is kill -9'd during the
test run. We should try harder to recover in this case. If we fail to
remove the test directory let's retry after (re-)chmod-ing it.

This doesn't need to be guarded by something that's equivalent to
"POSIXPERM" since if we don't support "chmod" we were about to fail
anyway.

Let's also discard any error output from (a possibly nonexisting)
"chmod", we'll fail on the subsequent "rm -rf" anyway, likewise for
the first "rm -rf" invocation, we don't want to get the "cannot
remove" output if we can get around it with the "chmod", but we do
want any error output from the second "rm -rf", in case that doesn't
fix the issue.

The lack of &&-chaining between the "chmod" and "rm -rf" is
intentional, if we fail the first "rm -rf", can't chmod, but then
succeed the second time around that's what we were hoping for. We just
want to nuke the directory, not carry forward every possible error
code or error message.

234383cd40 test-lib.sh: use "Bail out!" syntax on bad SANITIZE=leak use
Improve the "GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode added in
956d2e4639 (tests: add a test mode for SANITIZE=leak, run it in CI,
2021-09-23) to use a TAP "Bail out!" message when exiting. This will
cause the test run to exit immediately under a TAP consumer like
"prove(1)".

See 614fe01521 (test-lib: bail out when "-v" used under "prove",
2016-10-22) for the initial introduction of "Bail out!" to the
--verbose being amended here.

Before this compiling with "SANITIZE=" and running the tests with
"prove(1)" would cause all the tests to be run to the end (output
trimmed for fewer columns):

    $ GIT_TEST_PASSING_SANITIZE_LEAK=true make
    rm -f -r 'test-results'
    *** prove ***
    t0000-basic.sh ......... Dubious, test returned 1 (wstat 256, 0x100)
    No subtests run
    t0001-init.sh .......... Dubious, test returned 1 (wstat 256, 0x100)
    No subtests run
    [...output where we list every single t[0-9]*.sh file as failing snipped]

Whereas now we'll fail early, like this ("->" line wrapping added):

    $ GIT_TEST_PASSING_SANITIZE_LEAK=true make
    [...]

    t0000-basic.sh ..................................... Bailout called.  Further testing stopped:
    -> GIT_TEST_PASSING_SANITIZE_LEAK=true has no effect except when compiled with SANITIZE=leak
    FAILED--Further testing stopped: GIT_TEST_PASSING_SANITIZE_LEAK=true has no effect except
    -> when compiled with SANITIZE=leak
    make: *** [Makefile:53: prove] Error 1

This change also adds a red color to the "Bailout called" line, as
we're now using "say_color error". That improves existing output in
the case of e.g.:

    $ prove -j8 t[0-9]*.sh :: -v
    Bailout called.  Further testing stopped:  verbose mode forbidden under TAP harness; try --verbose-log
    FAILED--Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log

We don't need to have a "Bail out! " prefix when we're not running
under a TAP consumer (i.e. if test -n "$HARNESS_ACTIVE"), but let's
not make the output conditional on that. Showing it under e.g.:

    $ GIT_TEST_PASSING_SANITIZE_LEAK=true ./t0095-bloom.sh
    Bail out! GIT_TEST_PASSING_SANITIZE_LEAK=true has no effect except when compiled with SANITIZE=leak

Doesn't harm anything, and I don't think the (small) complexity of
only adding this if we're under "$HARNESS_ACTIVE" is worth it.

Mark some tests that match "*{mktree,commit,diff,grep,rm,merge,hunk}*"
as passing when git is compiled with SANITIZE=leak. They'll now be
listed as running under the "GIT_TEST_PASSING_SANITIZE_LEAK=true" test

These were picked because we still have a lot of failures in adjacent
areas, and we didn't have much if any coverage of e.g. grep and diff
before this change, we could still whitelist a lot more tests, but
let's stop for now.

without writing instead to make the run as dry as possible.

Use this opportunity to also make the hash_flags variable unsigned,

4ef91a2d79 commit: fix duplication regression in permission error output
Fix a regression in the error output emitted when .git/objects can't
be written to. Before 9c4d6c0297 (cache-tree: Write updated
cache-tree after commit, 2014-07-13) we'd emit only one "insufficient
permission" error, now we'll do so again.

The cause is rather straightforward, we've got WRITE_TREE_SILENT for
the use-case of wanting to prepare an index silently, quieting any
permission etc. error output. Then when we attempt to update to
that (possibly broken) index we'll run into the same errors again.

But with 9c4d6c0297 the gap between the cache-tree API and the object
store wasn't closed in terms of asking write_object_file() to be
silent. I.e. post-9c4d6c0297b the first call is to prepare_index(),
and after that we'll call prepare_to_commit(). We only want verbose
error output from the latter.

So let's add and use that facility with a corresponding HASH_SILENT
flag, its only user is cache-tree.c's update_one(), which will set it
if its "WRITE_TREE_SILENT" flag is set.

119b26d6b9 unwritable tests: assert exact error output
In preparation for fixing a regression where we started emitting some
of these error messages twice, let's assert what the output from "git
commit" and friends is now in the case of permission errors.

As noted in [1] using test_expect_failure to mark up a TODO test has
some unexpected edge cases, e.g. we don't want to break --run=3 by
skipping the "test_lazy_prereq" here. This pattern allows us to test
just the test_cmp (and the "cat", which shouldn't fail) with the added
"test_expect_failure", we'll flip that to a "test_expect_success" in
the next commit.

new file t/perf/config and using it as the system config file for perf
tests.  Future tests intended to measure gc performance can override
the setting locally or call "git gc" explicitly.

This fixes a breakage in p2000 caused by gc automatically emptying the
reflog due its fake dates from 2005 being older than 90 days.

5c5b29b459 cat-file: disable refs/replace with --batch-all-objects
When we're enumerating all objects in the object database, it doesn't
make sense to respect refs/replace. The point of this option is to
enumerate all of the objects in the database at a low level. By
definition we'd already show the replacement object's contents (under
its real oid), and showing those contents under another oid is almost
certainly working against what the user is trying to do.

Note that you could make the same argument for something like:

  git show-index <foo.idx |
  awk '{print $2}' |
  git cat-file --batch

but there we can't know in cat-file exactly what the user intended,
because we don't know the source of the input. They could be trying to
do low-level debugging, or they could be doing something more high-level
(e.g., imagine a porcelain built around cat-file for its object
accesses). So in those cases, we'll have to rely on the user specifying
"git --no-replace-objects" to tell us what to do.

One _could_ make an argument that "cat-file --batch" is sufficiently
low-level plumbing that it should not respect replace-objects at all
(and the caller should do any replacement if they want it).  But we have
been doing so for some time. The history is a little tangled:

  - looking back as far as v1.6.6, we would not respect replace refs for
    --batch-check, but would for --batch (because the former used
    sha1_object_info(), and the replace mechanism only affected actual
    object reads)

  - this discrepancy was made even weirder by 98e2092b50 (cat-file:
    teach --batch to stream blob objects, 2013-07-10), where we always
    output the header using the --batch-check code, and then printed the
    object separately. This could lead to "cat-file --batch" dying (when
    it notices the size or type changed for a non-blob object) or even
    producing bogus output (in streaming mode, we didn't notice that we
    wrote the wrong number of bytes).

  - that persisted until 1f7117ef7a (sha1_file: perform object
    replacement in sha1_object_info_extended(), 2013-12-11), which then
    respected replace refs for both forms.

So it has worked reliably this way for over 7 years, and we should make
sure it continues to do so. That could also be an argument that
--batch-all-objects should not change behavior (which this patch is
doing), but I really consider the current behavior to be an unintended
bug. It's a side effect of how the code is implemented (feeding the oids
back into oid_object_info() rather than looking at what we found while
reading the loose and packed object storage).

The implementation is straight-forward: we just disable the global
read_replace_refs flag when we're in --batch-all-objects mode. It would
perhaps be a little cleaner to change the flag we pass to
oid_object_info_extended(), but that's not enough. We also read objects
via read_object_file() and stream_blob_to_fd(). The former could switch
to its _extended() form, but the streaming code has no mechanism for
disabling replace refs. Setting the global flag works, and as a bonus,
it's impossible to have any "oops, we're sometimes replacing the object
and sometimes not" bugs in the output (like the ones caused by
98e2092b50 above).

The tests here cover the regular-input and --batch-all-objects cases,
for both --batch-check and --batch. There is a test in t6050 that covers
the regular-input case with --batch already, but this new one goes much
further in actually verifying the output (plus covering --batch-check
explicitly). This is perhaps a little overkill and the tests would be
simpler just covering --batch-check, but I wanted to make sure we're
checking that --batch output is consistent between the header and the
content. The global-flag technique used here makes that easy to get
right, but this is future-proofing us against regressions.

6a5c337922 pretty: colorize pattern matches in commit messages
The "git log" command limits its output to the commits that contain strings
matched by a pattern when the "--grep=<pattern>" option is used, but unlike
output from "git grep -e <pattern>", the matches are not highlighted,
making them harder to spot.

Teach the pretty-printer code to highlight matches from the
"--grep=<pattern>", "--author=<pattern>" and "--committer=<pattern>"
options (to view the last one, you may have to ask for --pretty=fuller).

Also, it must be noted that we are effectively greping the content twice
(because it would be a hassle to rework the existing matching code to do
a /g match and then pass it all down to the coloring code), however it only
slows down "git log --author=^H" on this repository by around 1-2%
(compared to v2.33.0), so it should be a small enough slow down to justify
the addition of the feature.

350b87cd65 userdiff-cpp: tighten word regex
Generally, word regex can be written such that they match tokens
liberally and need not model the actual syntax because it can be assumed
that the regex will only be applied to syntactically correct text.

The regex for cpp (C/C++) is too liberal, though. It regards these
sequences as single tokens:

   1+2
   1.5-e+2+f

and the following amalgams as one token:

   .l      as in str.length
   .f      as in str.find
   .e      as in str.erase

Tighten the regex in the following way:

- Accept + and - only in one position in the exponent. + and - are no
  longer regarded as the sign of a number and are treated by the
  catcher-all that is not visible in the driver's regex.

- Accept a leading decimal point only when it is followed by a digit.

For readability, factor hex- and binary numbers into an own term.

As a drive-by, this fixes that floating point numbers such as 12E5
(with upper-case E) were split into two tokens.

1cf93847c1 t4034/cpp: actually test that operator tokens are not split
8d96e7288f (t4034: bulk verify builtin word regex sanity, 2010-12-18)
added many tests with the intent to verify that operators consisting of
more than one symbol are kept together. These are tested by probing a
transition from, e.g., a!=b to x!=y, which results in the word-diff

  [-a-]{+x+}!=[-b-]{+y+}

But that proves only that the letters and operators are separate tokens.
To prove that != is an unseparable token, we have to probe a transition
from, e.g., a=b to a!=b having a word-diff

  a[-=-]{+!=+}b

that proves that the ! is not separate from the =.

In the post-image, add to or remove from operators a character that
turns it into another valid operator.

Change the identifiers used around operators such that the diff
algorithm does not have an incentive to match, e.g., a<b in one spot
in the pre-image with a<b elsewhere in the post-image.

Adjust the expected output to match the new differences. Notice that
there are some undesirable tokenizations around e, ., and -.  This will
be addressed in a later change.
