The following lines were not covered in a recent line-coverage test
against Git:
builtin/commit-graph.c
5b6653e5 244) progress = start_delayed_progress(
5b6653e5 268) stop_progress(&progress);
These statements are executed when both '--stdin-commits' and
'--progress' are passed. Introduce a trio of tests that exercise various
combinations of these options to ensure that these lines are covered.
More importantly, this is exercising a (somewhat) previously-ignored
feature of '--stdin-commits', which is that it respects '--progress'.
Prior to 5b6653e523 (builtin/commit-graph.c: dereference tags in
builtin, 2020-05-13), dereferencing input from '--stdin-commits' was
done inside of commit-graph.c.
Now that an additional progress meter may be generated from outside of
commit-graph.c, add a corresponding test to make sure that it also
respects '--[no]-progress'.
The other location that generates progress meter output (from d335ce8f24
(commit-graph.c: show progress of finding reachable commits,
2020-05-13)) is already covered by any test that passes '--reachable'.

A handful of tests in t5318 use 'test_line_count = 0 ...' to make sure
that some command does not write any output. While correct, it is more
idiomatic to use 'test_must_be_empty' instead. Switch the former
invocations to use the latter instead.

Portability fix for tests added recently.

f1e3df3169 (t: increase test coverage of signature verification output,
2020-03-04) adds GPG dependent tests to t4202 and t6200 that were found
problematic with at least OpenBSD 6.7.
Using an escaped '|' for alternations works only in some implementations
of grep (e.g. GNU and busybox).
It is not part of POSIX[1] and not supported by some BSD, macOS, and
possibly other POSIX compatible implementations.
Use `grep -E`, and write it using extended regular expression.

95acf11a3d ("diff: restrict when prefetching occurs", 2020-04-07) taught
diff to prefetch blobs in a more limited set of situations. These
limited situations include when the output format requires blob data,
and when inexact rename detection is needed.
There is an existing test case that tests inexact rename detection, but
it also uses an output format that requires blob data, resulting in the
inexact-rename-detection-only code not being tested. Update this test to
use the raw output format, which does not require blob data.
Thanks to Derrick Stolee for noticing this lapse in code coverage and
for doing the preliminary analysis [1].

Rather than teaching only one operation, like 'git fetch', how to write
down throughput to traces, we can learn about a wide range of user
operations that may seem slow by adding tooling to the progress library
itself. Operations which display progress are likely to be slow-running
and the kind of thing we want to monitor for performance anyways. By
showing object counts and data transfer size, we should be able to
make some derived measurements to ensure operations are scaling the way
we expect.

As diff_tree_oid() computes a diff, it will terminate early if the
total number of changed paths is strictly larger than max_changes.
This includes the directories that changed, not just the file paths.
However, only the file paths are reflected in the resulting diff
queue's "nr" value.
Use the "num_changes" from diffopt to check if the diff terminated
early. This is incredibly important, as it can result in incorrect
filters! For example, the first commit in the Linux kernel repo
reports only 471 changes, but since these are nested inside several
directories they expand to 513 "real" changes, and in fact the
total list of changes is not reported. Thus, the computed filter
for this commit is incorrect.
Demonstrate the subtle difference by using one fewer file change
in the 'get bloom filter for commit with 513 changes' test. Before,
this edited 513 files inside "bigDir" which hit this inequality.
However, dropping the file count by one demonstrates how the
previous inequality was incorrect but the new one is correct.

When computing a changed-path Bloom filter, we need to take the
files that changed from the diff computation and extract the parent
directories. That way, a directory pathspec such as "Documentation"
could match commits that change "Documentation/git.txt".
However, the current code does a poor job of this process. The paths
are added to a hashmap, but we do not check if an entry already
exists with that path. This can create many duplicate entries and
cause the filter to have a much larger length than it should. This
means that the filter is more sparse than intended, which helps the
false positive rate, but wastes a lot of space.
Properly use hashmap_get() before hashmap_add(). Also be sure to
include a comparison function so these can be matched correctly.
This has an effect on a test in t0095-bloom.sh. This makes sense,
there are ten changes inside "smallDir" so the total number of
paths in the filter should be 11. This would result in 11 * 10 bits
required, and with 8 bits per byte, this results in 14 bytes.

Tree entries are sorted in path order, meaning that directory names get
a slash ('/') appended implicitly. Git fsck checks if trees contains
consecutive duplicates, but due to that ordering there can be
non-consecutive duplicates as well if one of them is a directory and the
other one isn't. Such a tree cannot be fully checked out.
Find these duplicates by recording candidate file names on a stack and
check candidate directory names against that stack to find matches.

Perforce allows you commit files and directories with the same name,
so you could have files //depot/foo and //depot/foo/bar both checked
in. A p4 sync of a repository in this state fails. Deleting one of
the files recovers the repository.
When this happens we want git-p4 to recover in the same way as
perforce.
Note that Perforce has this change in their 2017.1 version:
Bugs fixed in 2017.1
#1489051 (Job #2170) **
Submitting a file with the same name as an existing depot
directory path (or vice versa) will now be rejected.
so people hopefully will not creating damaged Perforce repos
anymore, but "git p4" needs to be able to interact with already
corrupt ones.

When selecting a batch of pack-files to repack in the "git
multi-pack-index repack" command, Git should respect the
repack.packKeptObjects config option. When false, this option says that
the pack-files with an associated ".keep" file should not be repacked.
This config value is "false" by default.
There are two cases for selecting a batch of objects. The first is the
case where the input batch-size is zero, which specifies "repack
everything". The second is with a non-zero batch size, which selects
pack-files using a greedy selection criteria. Both of these cases are
updated and tested.

When rearranging the todo list so that the fixups/squashes are reordered
just after the commits they intend to fix up, we use two arrays to
maintain that list: `next` and `tail`.
The idea is that `next[i]`, if set to a non-negative value, contains the
index of the item that should be rearranged just after the `i`th item.
To avoid having to walk the entire `next` chain when appending another
fixup/squash, we also store the end of the `next` chain in `tail[i]`.
The logic we currently use to update these array items is based on the
assumption that given a fixup/squash item at index `i`, we just found
the index `i2` indicating the first item in that fixup chain.
However, as reported by Paul Ganssle, that need not be true: the special
form `fixup! <commit-hash>` is allowed to point to _another_ fixup
commit in the middle of the fixup chain.
Example:
* 0192a To fixup
* 02f12 fixup! To fixup
* 03763 fixup! To fixup
* 04ecb fixup! 02f12
Note how the fourth commit targets the second commit, which is already a
fixup that targets the first commit.
Previously, we would update `next` and `tail` under our assumption that
every `fixup!` commit would find the start of the `fixup!`/`squash!`
chain. This would lead to a segmentation fault because we would actually
end up with a `next[i]` pointing to a `fixup!` but the corresponding
`tail[i]` pointing nowhere, which would the lead to a segmentation
fault.
Let's fix this by _inserting_, rather than _appending_, the item. In
other words, if we make a given line successor of another line, we do
not simply forget any previously set successor of the latter, but make
it a successor of the former.
In the above example, at the point when we insert 04ecb just after
02f12, 03763 would already be recorded as a successor of 04ecb, and we
now "squeeze in" 04ecb.
To complete the idea, we now no longer assume that `next[i]` pointing to
a line means that `last[i]` points to a line, too. Instead, we extend
the concept of `last` to cover also partial `fixup!`/`squash!` chains,
i.e. chains starting in the middle of a larger such chain.
In the above example, after processing all lines, `last[0]`
(corresponding to 0192a) would point to 03763, which indeed is the end
of the overall `fixup!` chain, and `last[1]` (corresponding to 02f12)
would point to 04ecb (which is the last `fixup!` targeting 02f12, but it
has 03763 as successor, i.e. it is not the end of overall `fixup!`
chain).

Because of the request/response model of protocol v2, the
upload_pack_v2() function is sometimes called twice in the same
process, while 'struct list_objects_filter_options filter_options'
was declared as static at the beginning of 'upload-pack.c'.
This made the check in list_objects_filter_die_if_populated(), which
is called by process_args(), fail the second time upload_pack_v2() is
called, as filter_options had already been populated the first time.
To fix that, filter_options is not static any more. It's now owned
directly by upload_pack(). It's now also part of 'struct
upload_pack_data', so that it's owned indirectly by upload_pack_v2().
In the long term, the goal is to also have upload_pack() use
'struct upload_pack_data', so adding filter_options to this struct
makes more sense than to have it owned directly by upload_pack_v2().
This fixes the first of the 2 bugs documented by d0badf8797
(partial-clone: demonstrate bugs in partial fetch, 2020-02-21).

Occasionally a failure a user is seeing may be related to a specific
hook which is being run, perhaps without the user realizing. While the
contents of hooks can be sensitive - containing user data or process
information specific to the user's organization - simply knowing that a
hook is being run at a certain stage can help us to understand whether
something is going wrong.
Without a definitive list of hook names within the code, we compile our
own list from the documentation. This is likely prone to bitrot, but
designing a single source of truth for acceptable hooks is too much
overhead for this small change to the bugreport tool.
