We try to delete the non-existing tag "anothertag", but for the
verifications, we check that the tag "myhead" doesn't exist. "myhead"
isn't used in this test except for this checking. Comparing to the test
two tests earlier, it looks like a copy-paste mistake.
Perhaps it's overkill to check that `git tag -d` didn't decide to
*create* a tag. But since we're trying to be this careful, let's
actually check the correct tag. While we're doing this, let's use a more
descriptive tag name instead -- "nonexistingtag" should be obvious.

Unlike previous conversions to C, where we started with a built-in
helper, we start this conversion by adding an interception in the
`run_add_interactive()` function when the new opt-in
`add.interactive.useBuiltin` config knob is turned on (or the
corresponding environment variable `GIT_TEST_ADD_I_USE_BUILTIN`), and
calling the new internal API function `run_add_i()` that is implemented
directly in libgit.a.
At this point, the built-in version of `git add -i` only states that it
cannot do anything yet. In subsequent patches/patch series, the
`run_add_i()` function will gain more and more functionality, until it
is feature complete. The whole arc of the conversion can be found in the
PRs #170-175 at https://github.com/gitgitgadget/git.
The "--helper approach" can unfortunately not be used here: on Windows
we face the very specific problem that a `system()` call in
Perl seems to close `stdin` in the parent process when the spawned
process consumes even one character from `stdin`. Which prevents us from
implementing the main loop in C and still trying to hand off to the Perl
script.
The very real downside of the approach we have to take here is that the
test suite won't pass with `GIT_TEST_ADD_I_USE_BUILTIN=true` until the
conversion is complete (the `--helper` approach would have let it pass,
even at each of the incremental conversion steps).

In 'do_apply_stash()' we refresh the index in the end. Since
34933d0eff ("stash: make sure to write refreshed cache", 2019-09-11),
we also write that refreshed index when --quiet is given to 'git stash
apply'.
However if '--index' is not given to 'git stash apply', we also
discard the index in the else clause just before. We need to do so
because we use an external 'git update-index --add --stdin', which
leads to an out of date in-core index.
Later we call 'refresh_and_write_cache', which now leads to writing
the discarded index, which means we essentially write an empty index
file. This is obviously not correct, or the behaviour the user
wanted. We should not modify the users index without being asked to
do so.
Make sure to re-read the index after discarding the current in-core
index, to avoid dealing with outdated information. Instead we could
also drop the 'discard_cache()' + 'read_cache()', however that would
make it easy to fall into the same trap as 34933d0eff did, so it's
better to avoid that.
We can also drop the 'refresh_and_write_cache' completely in the quiet
case. Previously in legacy stash we relied on 'git status' to refresh
the index after calling 'git read-tree' when '--index' was passed to
'git apply'. However the 'reset_tree()' call that replaced 'git
read-tree' always passes options that are equivalent to '-m', making
the refresh of the index unnecessary.

With './t1234-foo.sh -r 5,6' we can run only specific test cases in a

Avoid this unnecessary prereq evaluation by checking the list of test

so prereqs necessary for tests skipped that way were not evaluated.

This patch fixes an extreme slowdown in pack-objects when you have more
than 1023 packs. See below for numbers.
Since 43fa44fa3b (pack-objects: move in_pack out of struct object_entry,
2018-04-14), we use a complicated system to save some per-object memory.
Each object_entry structs gets a 10-bit field to store the index of the
pack it's in. We map those indices into pointers using
packing_data->in_pack_by_idx, which we initialize at the start of the
program. If we have 2^10 or more packs, then we instead create an array
of pack pointers, one per object. This is packing_data->in_pack.
So far so good. But there's one other tricky case: if a new pack arrives
after we've initialized in_pack_by_idx, it won't have an index yet. We
solve that by calling oe_map_new_pack(), which just switches on the fly
to the less-optimal in_pack mechanism, allocating the array and
back-filling it for already-seen objects.
But that logic kicks in even when we've switched to it already (whether
because we really did see a new pack, or because we had too many packs
in the first place). The result doesn't produce a wrong outcome, but
it's very slow. What happens is this:
- imagine you have a repo with 500k objects and 2000 packs that you
want to repack.
- before looking at any objects, we call prepare_in_pack_by_idx(). It
starts allocating an index for each pack. On the 1024th pack, it
sees there are too many, so it bails, leaving in_pack_by_idx as
NULL.
- while actually adding objects to the packing list, we call
oe_set_in_pack(), which checks whether the pack already has an
index. If it's one of the packs after the first 1023, then it
doesn't have one, and we'll call oe_map_new_pack().
But there's no useful work for that function to do. We're already
using in_pack, so it just uselessly walks over the complete list of
objects, trying to backfill in_pack.
And we end up doing this for almost 1000 packs (each of which may be
triggered by more than one object). And each time it triggers, we
may iterate over up to 500k objects. So in the absolute worst case,
this is quadratic in the number of objects.
The solution is simple: we don't need to bother checking whether the
pack has an index if we've already converted to using in_pack, since by
definition we're not going to use it. So we can just push the "does the
pack have a valid index" check down into that half of the conditional,
where we know we're going to use it.
The current test in p5303 sadly doesn't notice this problem, since it
maxes out at 1000 packs. If we add a new test to it at 2000 packs, it
does show the improvement:
Test HEAD^ HEAD
----------------------------------------------------------------------
5303.12: repack (2000) 26.72(39.68+0.67) 15.70(28.70+0.66) -41.2%
However, these many-pack test cases are rather expensive to run, so
adding larger and larger numbers isn't appealing. Instead, we can show
it off more easily by using GIT_TEST_FULL_IN_PACK_ARRAY, which forces us
into the absolute worst case: no pack has an index, so we'll trigger
oe_map_new_pack() pointlessly for every single object, making it truly
quadratic.
Here are the numbers (on git.git) with the included change to p5303:
Test HEAD^ HEAD
----------------------------------------------------------------------
5303.3: rev-list (1) 2.05(1.98+0.06) 2.06(1.99+0.06) +0.5%
5303.4: repack (1) 33.45(33.46+0.19) 2.75(2.73+0.22) -91.8%
5303.6: rev-list (50) 2.07(2.01+0.06) 2.06(2.01+0.05) -0.5%
5303.7: repack (50) 34.21(35.18+0.16) 3.49(4.50+0.12) -89.8%
5303.9: rev-list (1000) 2.87(2.78+0.08) 2.88(2.80+0.07) +0.3%
5303.10: repack (1000) 41.26(51.30+0.47) 10.75(20.75+0.44) -73.9%
Again, those improvements aren't realistic for the 1-pack case (because
in the real world, the full-array solution doesn't kick in), but it's
more useful to be testing the more-complicated code path.
While we're looking at this issue, we'll tweak one more thing: in
oe_map_new_pack(), we call REALLOC_ARRAY(pack->in_pack). But we'd never
expect to get here unless we're back-filling it for the first time, in
which case it would be NULL. So let's switch that to ALLOC_ARRAY() for
clarity, and add a BUG() to document the expectation. Unfortunately this
code isn't well-covered in the test suite because it's inherently racy
(it only kicks in if somebody else adds a new pack while we're in the
middle of repacking).

When running Git commands quickly -- such as in a shell script or the
test suite -- the Git commands frequently complete and start again
during the same second. The example fsmonitor hooks to integrate with
Watchman truncate the nanosecond times to seconds. In principle, this is
fine, as Watchman claims to use inclusive comparisons [1]. The result
should only be an over-representation of the changed paths since the
last Git command.
However, Watchman's own documentation claims "Using a timestamp is prone
to race conditions in understanding the complete state of the file tree"
[2]. All of their documented examples use a "clockspec" that looks like
'c:123:234'. Git should eventually learn how to store this type of
string to provide a stronger integration, but that will be a more
invasive change.
When using GIT_TEST_FSMONITOR="$(pwd)/t7519/fsmonitor-watchman", scripts
such as t7519-wtstatus.sh fail due to these race conditions. In fact,
running any test script with GIT_TEST_FSMONITOR pointing at
t/t7519/fsmonitor-wathcman will cause failures in the test_commit
function. The 'git add "$indir$file"' command fails due to not enough
time between the creation of '$file' and the 'git add' command.
For now, subtract one second from the timestamp we pass to Watchman.
This will make our window large enough to avoid these race conditions.
Increasing the window causes tests like t7519-wtstatus.sh to pass.
When the integration was introduced in def437671 (fsmonitor: add a
sample integration script for Watchman, 2018-09-22), the query included
an expression that would ignore files created and deleted in that
window. The performance reason for this change was to ignore temporary
files created by a build between Git commands. However, this causes
failures in script scenarios where Git is creating or deleting files
quickly.
When using GIT_TEST_FSMONITOR as before, t2203-add-intent.sh fails
due to this add-and-delete race condition.
By removing the "expression" from the Watchman query, we remove this
race condition. It will lead to some performance degradation in the case
of users creating and deleting temporary files inside their working
directory between Git commands. However, that is a cost we need to pay
to be correct.

When calling `git stash` while changes were staged for files that are
marked with the `skip-worktree` bit (e.g. files that are excluded in a
sparse checkout), the files are recorded as _deleted_ instead.
The reason is that `git stash` tries to construct the tree reflecting
the worktree essentially by copying the index to a temporary one and
then updating the files from the worktree. Crucially, it calls `git
diff-index` to update also those files that are in the HEAD but have
been unstaged in the index.
However, when the temporary index is updated via `git update-index --add
--remove`, skip-worktree entries mark the files as deleted by mistake.
Let's use the newly-introduced `--ignore-skip-worktree-entries` option
of `git update-index` to prevent exactly this from happening.
Note that the regression test case deliberately avoids replicating the
scenario described above and instead tries to recreate just the symptom.

While `git update-index` mostly ignores paths referring to index entries
whose skip-worktree bit is set, in b4d1690df1 (Teach Git to respect

entirely obvious, the `--remove` option was made special: it _does_
remove index entries even if their skip-worktree bit is set.
Seeing as this behavior has been in place for a decade now, it does not
make sense to change it.
However, in preparation for fixing a bug in `git stash` where it
pretends that skip-worktree entries have actually been removed, we need
a mode where `git update-index` leaves all skip-worktree entries alone,
even if the `--remove` option was passed.

"worktree add" internally calls "reset --hard", but if
submodule.recurse is set, reset tries to recurse into
initialized submodules, which makes start_command try to
cd into non-existing submodule paths and die.
Fix that by making sure that the call to reset in "worktree add"
does not recurse.

Ever since worktrees were introduced, the `git_path()` function _really_
needed to be called e.g. to get at the path to `logs/HEAD` (`HEAD` is
specific to the worktree, and therefore so is its reflog). However, the
wrong path is returned for `logs/HEAD.lock`.
This does not matter as long as the Git executable is doing the asking,
as the path for that `logs/HEAD.lock` file is constructed from
`git_path("logs/HEAD")` by appending the `.lock` suffix.
However, Git GUI just learned to use `--git-path` instead of appending
relative paths to what `git rev-parse --git-dir` returns (and as a
consequence not only using the correct hooks directory, but also using
the correct paths in worktrees other than the main one). While it does
not seem as if Git GUI in particular is asking for `logs/HEAD.lock`,
let's be safe rather than sorry.
Side note: Git GUI _does_ ask for `index.lock`, but that is already
resolved correctly, due to `update_common_dir()` preferring to leave
unknown paths in the (worktree-specific) git directory.

Without this, you cannot use `--run=<...>` to skip that part, and a run
with `--run=0` (which is a common way to determine the test case number
corresponding to a given test case title).

Commit 90cf590f53 (fsck: optionally show more helpful info for broken
links, 2016-07-17) added a system for decorating objects with names. The
code is split across builtin/fsck.c (which gives the initial names) and
fsck.c (which adds to the names as it traverses the object graph). This
leads to some duplication, where both sites have near-identical
describe_object() functions (the difference being that the one in
builtin/fsck.c uses a circular array of buffers to allow multiple calls
in a single printf).
Let's provide a unified object_name API for fsck. That lets us drop the
duplication, as well as making the interface boundaries more clear
(which will let us refactor the implementation more in a future patch).
We'll leave describe_object() in builtin/fsck.c as a thin wrapper around
the new API, as it relies on a static global to make its many callers a
bit shorter.
We'll also convert the bare add_decoration() calls in builtin/fsck.c to
put_object_name(). This fixes two minor bugs:
1. We leak many small strings. add_decoration() has a last-one-wins
approach: it updates the decoration to the new string and returns
the old one. But we ignore the return value, leaking the old
string. This is quite common to trigger, since we look at reflogs:
the tip of any ref will be described both by looking at the actual
ref, as well as the latest reflog entry. So we'd always end up
leaking one of those strings.
2. The last-one-wins approach gives us lousy names. For instance, we
first look at all of the refs, and then all of the reflogs. So
rather than seeing "refs/heads/master", we're likely to overwrite
it with "HEAD@{12345678}". We're generally better off using the
first name we find.
And indeed, the test in t1450 expects this ugly HEAD@{} name. After
this patch, we've switched to using fsck_put_object_name()'s
first-one-wins semantics, and we output the more human-friendly
"refs/tags/julius" (and the test is updated accordingly).

If we can't parse a commit, then parse_commit() will return an error
code. But it _also_ sets the "parsed" flag, which tells us not to bother
trying to re-parse the object. That means that subsequent parses have no
idea that the information in the struct may be bogus. I.e., doing this:
parse_commit(commit);
...
if (parse_commit(commit) < 0)
die("commit is broken");
will never trigger the die(). The second parse_commit() will see the
"parsed" flag and quietly return success.
There are two obvious ways to fix this:
1. Stop setting "parsed" until we've successfully parsed.
2. Keep a second "corrupt" flag to indicate that we saw an error (and
when the parsed flag is set, return 0/-1 depending on the corrupt
flag).
This patch does option 1. The obvious downside versus option 2 is that
we might continually re-parse a broken object. But in practice,
corruption like this is rare, and we typically die() or return an error
in the caller. So it's OK not to worry about optimizing for corruption.
And it's much simpler: we don't need to use an extra bit in the object
struct, and callers which check the "parsed" flag don't need to learn
about the corrupt bit, too.
There's no new test here, because this case is already covered in t5318.
Note that we do need to update the expected message there, because we
now detect the problem in the return from "parse_commit()", and not with
a separate check for a NULL tree. In fact, we can now ditch that
explicit tree check entirely, as we're covered robustly by this change
(and the previous recent change to treat a NULL tree as a parse error).
We'll also give tags the same treatment. I don't know offhand of any
cases where the problem can be triggered (it implies somebody ignoring a
parse error earlier in the process), but consistently returning an error
should cause the least surprise.
