We started unconditionally testing with CGIPassAuth directive but
it is unavailable in older Apache that ships with CentOS 7 that has
about a year of shelf-life still left. The test has conditionally
been disabled when running with an ancient Apache. This was a fix

When "git send-email" that uses the validate hook is fed a message

t9001: mark the script as no longer leak checker clean
send-email: clear the $message_id after validation
We may allocate a message-id string via gen_message_id(), but we never
free it, causing a small leak. This can be demonstrated by running t9001
with a leak-checking build. The offending test is the one touched by
3ece9bf0f9 (send-email: clear the $message_id after validation,
2023-05-17), but the leak is much older than that. The test was simply
unlucky enough to trigger the leaking code path for the first time.
We can fix this by freeing the string at the end of the function. We can
also re-mark the test script as leak-free, effectively reverting
20bd08aefb (t9001: mark the script as no longer leak checker clean,

Commit 988aad99b4 (t5563: add tests for basic and anoymous HTTP access,
2023-02-27) added tests that require Apache to support the CGIPassAuth
directive, which was added in Apache 2.4.13. This is fairly old (~8
years), but recent enough that we still encounter it in the wild (e.g.,
RHEL/CentOS 7, which is not EOL until June 2024).
We can live with skipping the new tests on such a platform. But
unfortunately, since the directive is used unconditionally in our
apache.conf, it means the web server fails to start entirely, and we
cannot run other HTTP tests at all (e.g., the basic ones in t5551).
We can fix that by making the config conditional, and only triggering it
for t5563. That solves the problem for t5551 (which then ignores the
directive entirely). For t5563, we'd see apache complain in start_httpd;
with the default setting of GIT_TEST_HTTPD, we'd then skip the whole
script.
But that leaves one small problem: people may set GIT_TEST_HTTPD=1
explicitly, which instructs the tests to fail (rather than skip) when we
can't start the webserver (to avoid accidentally missing some tests).
This could be worked around by having the user manually set
GIT_SKIP_TESTS on a platform with an older Apache. But we can be a bit
friendlier by doing the version check ourselves and setting an
appropriate prereq. We'll use the (lack of) prereq to then skip the rest
of t5563. In theory we could use the prereq to skip individual tests, but
in practice this whole script depends on it.

The index is read in 'cmd_diff_tree' at two points:
1. The first index read was added in fd66bcc31f (diff-tree: read the
index so attribute checks work in bare repositories, 2017-12-06) to deal
with reading '.gitattributes' content. 77efbb366a (attr: be careful
about sparse directories, 2021-09-08) established that, in a sparse
index, we do _not_ try to load a '.gitattributes' file from within a
sparse directory.
2. The second index access point is involved in rename detection,
specifically when reading from stdin.This was initially added in
f0c6b2a2fd ([PATCH] Optimize diff-tree -[CM]--stdin, 2005-05-27), where
'setup' was set to 'DIFF_SETUP_USE_SIZE_CACHE |DIFF_SETUP_USE_CACHE'.
That assignment was later modified to drop the'DIFF_SETUP_USE_CACHE' in
ff7fe37b05 (diff.c: move read_index() code back to the caller,
2018-08-13).However, 'DIFF_SETUP_USE_SIZE_CACHE' seems to be unused as
of 6e0b8ed6d3 (diff.c: do not use a separate "size cache"., 2007-05-07)
and nothing about 'detect_rename' otherwise indicates index usage.
Hence we can just set the requires-full-index to false for "diff-tree".
Add tests that verify that 'git diff-tree' behaves correctly when the
sparse index is enabled and test to ensure the index is not expanded.
The `p2000` tests demonstrate a ~98% execution time reduction for
'git diff-tree' using a sparse index:

Recently git-send-email started parsing the same message twice, once
to validate _all_ the message before sending even the first one, and
then after the validation hook is happy and each message gets sent,
to read the contents to find out where to send to etc.
Unfortunately, the effect of reading the messages for validation
lingered even after the validation is done. Namely $message_id gets
assigned if exists in the input files but the variable is global,
and it is not cleared before pre_process_file runs. This causes
reading a message without a message-id followed by reading a message
with a message-id to misbehave---the sub reports as if the message
had the same id as the previously written one.
Clear the variable before starting to read the headers in
pre_process_file.

When cloning an empty repository, protocol versions 0 and 1 currently
offer nothing but the header and flush packets for the /info/refs
endpoint. This means that no capabilities are provided, so the client
side doesn't know what capabilities are present.
However, this does pose a problem when working with SHA-256
repositories, since we use the capabilities to know the remote side's
object format (hash algorithm). As of 8b214c2e9d ("clone: propagate
object-format when cloning from void", 2023-04-05), this has been fixed
for protocol v2, since there we always read the hash algorithm from the
remote.
Fortunately, the push version of the protocol already indicates a clue
for how to solve this. When the /info/refs endpoint is accessed for a
push and the remote is empty, we include a dummy "capabilities^{}" ref
pointing to the all-zeros object ID. The protocol documentation already
indicates this should _always_ be sent, even for fetches and clones, so
let's just do that, which means we'll properly announce the hash
algorithm as part of the capabilities. This just works with the
existing code because we share the same ref code for fetches and clones,
and libgit2, JGit, and dulwich do as well.
There is one minor issue to fix, though. If we called send_ref with
namespaces, we would return NULL with the capabilities entry, which
would cause a crash. Instead, let's refactor out a function to print
just the ref itself without stripping the namespace and use it for our
special capabilities entry.
Add several sets of tests for HTTP as well as for local clones. The
behavior can be slightly different for HTTP versus a local or SSH clone
because of the stateless-rpc functionality, so it's worth testing both.

These tests use "! test_path_is_dir" or "! test_path_is_file" to
ensure that the path is not recursively checked out or "submodule

Use "test_path_is_missing" to assert that the path does not exist,
instead of negating test_path_is_* helpers; they are designed to be

In this test, a path (some_dir) that is originally a directory is to
be removed and then to be replaced with a file of the same name.
The expectation is that the path becomes a file at the end.
However, "! test_path_is_dir some_dir" is used to catch a breakage
that leaves the path as a directory.
But as with all the "test_path_is..." helpers, this use of the
helper makes it loud when the expectation (i.e. it is a directory)
is met, and otherwise is silent when it is not---this does not help
debugging.
Be more explicit and state that we expect the path to become a file.

As a way to assert the path 'foo' is missing, "! test_path_exists
foo" is a poor way to do so, as the helper is designed to complain

For regular, non-`--rebase-merges` runs, there is very little work to do
for the parser when determining the total number of commands in a rebase
script: it is simply the number of lines after stripping the commented
lines and then trimming the trailing empty line, if any.
The `--rebase-merges` mode complicates things by introducing empty lines
and comments in the middle of the script. These should _not_ be counted
as commands, and indeed, when an interactive rebase is interrupted and
subsequently resumed, the total number of commands can magically shrink,
sometimes dramatically.
The reason for this strange behavior is that empty lines _are_ counted
in `edit_todo_list()` (but not the comments, as they are stripped via
`strbuf_stripspace(..., 1)`, which is a bug.
Let's fix this so that the correct total number is shown from the
get-go, by carefully adjusting it according to what's in the rebase
script. Extra care needs to be taken in case the user edits the script:
the number of commands might be different after the user edited than
beforehand.
Note: Even though commented lines are skipped in `edit_todo_list()`, we
still need to handle `TODO_COMMENT` items by decrementing the
already-incremented `total_nr` again: empty lines are also marked as
`TODO_COMMENT`.

Allow users to be more selective over which refs to pack by adding an

The existing options allow some measure of selectivity. By default
git-pack-refs packs all tags. --all can be used to include all refs,
and the previous commit added the ability to exclude certain refs with
--exclude.
While these knobs give the user some selection over which refs to pack,
it could be useful to give more control. For instance, a repository may
have a set of branches that are rarely updated and would benefit from
being packed. --include would allow the user to easily include a set of

The 'git merge-tree' command handles creating root trees for merges
without using the worktree. This is a critical operation in many Git
hosts, as they typically store bare repositories.
This builtin does not load the default Git config, which can have
several important ramifications.
In particular, one config that is loaded by default is
core.useReplaceRefs. This is typically disabled in Git hosts due to
the ability to spoof commits in strange ways.
Since this config is not loaded specifically during merge-tree, users
were previously able to use refs/replace/ references to make pull
requests that looked valid but introduced malicious content. The
resulting merge commit would have the correct commit history, but the
malicious content would exist in the root tree of the merge.
The fix is simple: load the default Git config in cmd_merge_tree().
This may also fix other behaviors that are effected by reading default
config. The only possible downside is a little extra computation time
spent reading config. The config parsing is placed after basic argument
parsing so it does not slow down usage errors.

Introduce a new machine-parseable "porcelain" output format that is
supposed to fix this shortcoming. This output format is intended to
provide information about every reference that is about to be updated,
the old object ID that the reference has been pointing to and the new
object ID it will be updated to. Furthermore, the output format provides
the same flags as the human-readable format to indicate basic conditions
for each reference update like whether it was a fast-forward update, a
branch deletion, a rejected update or others.
The output format is quite simple:
```
<flag> <old-object-id> <new-object-id> <local-reference>\n
```
We assume two conditions which are generally true:
- The old and new object IDs have fixed known widths and cannot
contain spaces.
- References cannot contain newlines.
With these assumptions, the output format becomes unambiguously
parseable. Furthermore, given that this output is designed to be
consumed by scripts, the machine-readable data is printed to stdout
instead of stderr like the human-readable output is. This is mostly done
so that other data printed to stderr, like error messages or progress
meters, don't interfere with the parseable data.
A notable ommission here is that the output format does not include the
remote from which a reference was fetched, which might be important
information especially in the context of multi-remote fetches. But as
such a format would require us to print the remote for every single
reference update due to parallelizable fetches it feels wasteful for the
most likely usecase, which is when fetching from a single remote.
In a similar spirit, a second restriction is that this cannot be used
with `--recurse-submodules`. This is because any reference updates would
be ambiguous without also printing the repository in which the update
happens.
Considering that both multi-remote and submodule fetches are user-facing
features, using them in conjunction with `--porcelain` that is intended
for scripting purposes is likely not going to be useful in the majority
of cases. With that in mind these restrictions feel acceptable. If
usecases for either of these come up in the future though it is easy
enough to add a new "porcelain-v2" format that adds this information.

`store_updated_refs()` parses the remote reference for two purposes:
- It gets used as a note when writing FETCH_HEAD.
- It is passed through to `display_ref_update()` to display
updated references in the following format:
```
* branch master -> master
```
In most cases, the parsed remote reference is the prettified reference
name and can thus be used for both cases. But if the remote reference is
HEAD, the parsed remote reference becomes empty. This is intended when
we write the FETCH_HEAD, where we skip writing the note in that case.
But when displaying the updated references this leads to inconsistent
output where the left-hand side of reference updates is missing in some
cases:
```
$ git fetch origin HEAD HEAD:explicit-head :implicit-head main
From https://github.com/git/git
* branch HEAD -> FETCH_HEAD
* [new ref] -> explicit-head
* [new ref] -> implicit-head
* branch main -> FETCH_HEAD
```
This behaviour has existed ever since the table-based output has been
introduced for git-fetch(1) via 165f390250 (git-fetch: more terse fetch
output, 2007-11-03) and was never explicitly documented either in the
commit message or in any of our tests. So while it may not be a bug per
se, it feels like a weird inconsistency and not like it was a concious
design decision.
The logic of how we compute the remote reference name that we ultimately
pass to `display_ref_update()` is not easy to follow. There are three
different cases here:
- When the remote reference name is "HEAD" we set the remote
reference name to the empty string. This is the case that causes
the left-hand side to go missing, where we would indeed want to
print "HEAD" instead of the empty string. This is what
`prettify_refname()` would return.
- When the remote reference name has a well-known prefix then we
strip this prefix. This matches what `prettify_refname()` does.
- Otherwise, we keep the fully qualified reference name. This also
matches what `prettify_refname()` does.
As the return value of `prettify_refname()` would do the correct thing
for us in all three cases, we can thus fix the inconsistency by passing
through the full remote reference name to `display_ref_update()`, which
learns to call `prettify_refname()`. At the same time, this also
simplifies the code a bit.
Note that this patch also changes formatting of the block that computes
the "kind" (which is the category like "branch" or "tag") and "what"
(which is the prettified reference name like "master" or "v1.0")
variables. This is done on purpose so that it is part of the diff,
hopefully making the change easier to comprehend.

When running `git fetch --no-recurse-submodules`, the exectation is that
we don't fetch any submodules. And while this works for fetches of a
single remote, it doesn't when fetching multiple remotes at once. The
result is that we do recurse into submodules even though the user has
explicitly asked us not to.
This is because while we pass on `--recurse-submodules={yes,on-demand}`
if specified by the user, we don't pass on `--no-recurse-submodules` to
the subprocess spawned to perform the submodule fetch.
Fix this by also forwarding this flag as expected.

We have a small helper function called "verbose", with the idea that you
can write:
verbose foo
to get a message to stderr when the "foo" command fails, even if it does
not produce any output itself. This goes back to 8ad1652418 (t5304: use
helper to report failure of "test foo = bar", 2014-10-10). It does work,
but overall it has not been a big success for two reasons:
1. Test writers have to remember to put it there (and the resulting
test code is longer as a result).
2. It doesn't handle the opposite case (we expect "foo" to fail, but
it succeeds), leading to inconsistencies in tests (which you can
see in many hunks of this patch, e.g. ones involving "has_cr").
Most importantly, we added a136f6d8ff (test-lib.sh: support -x option
for shell-tracing, 2014-10-10) at the same time, and it does roughly the
same thing. The output is not quite as succinct as "verbose", and you
have to watch out for stray shell-traces ending up in stderr. But it
solves both of the problems above, and has clearly become the preferred
tool.
Let's consider the "verbose" function a failed experiment and remove the
last few callers (which are all many years old, and have been dwindling
as we remove them from scripts we touch for other reasons). It will be
one less thing for new test writers to see and wonder if they should be
using themselves.

main point of the test), but it doesn't hurt to be careful.
In all but one case here we're piping "ls-files --stage" to cut off the

When reachability bitmap coverage exists in a repository, Git will use a
different (and hopefully faster) traversal to compute revision walks.
Consider a set of positive and negative tips (which we'll refer to with
their standard bitmap parlance by "wants", and "haves"). In order to
figure out what objects exist between the tips, the existing traversal
in `prepare_bitmap_walk()` does something like:
1. Consider if we can even compute the set of objects with bitmaps,
and fall back to the usual traversal if we cannot. For example,
pathspec limiting traversals can't be computed using bitmaps (since
they don't know which objects are at which paths). The same is true
of certain kinds of non-trivial object filters.
2. If we can compute the traversal with bitmaps, partition the
(dereferenced) tips into two object lists, "haves", and "wants",
based on whether or not the objects have the UNINTERESTING flag,
respectively.
3. Fall back to the ordinary object traversal if either (a) there are
more than zero haves, none of which are in the bitmapped pack or
MIDX, or (b) there are no wants.
4. Construct a reachability bitmap for the "haves" side by walking
from the revision tips down to any existing bitmaps, OR-ing in any
bitmaps as they are found.
5. Then do the same for the "wants" side, stopping at any objects that
appear in the "haves" bitmap.
6. Filter the results if any object filter (that can be easily
computed with bitmaps alone) was given, and then return back to the
caller.
When there is good bitmap coverage relative to the traversal tips, this
walk is often significantly faster than an ordinary object traversal
because it can visit far fewer objects.
But in certain cases, it can be significantly *slower* than the usual
object traversal. Why? Because we need to compute complete bitmaps on
either side of the walk. If either one (or both) of the sides require
walking many (or all!) objects before they get to an existing bitmap,
the extra bitmap machinery is mostly or all overhead.
One of the benefits, however, is that even if the walk is slower, bitmap
traversals are guaranteed to provide an *exact* answer. Unlike the
traditional object traversal algorithm, which can over-count the results
by not opening trees for older commits, the bitmap walk builds an exact
reachability bitmap for either side, meaning the results are never
over-counted.
But producing non-exact results is OK for our traversal here (both in
the bitmap case and not), as long as the results are over-counted, not
under.
Relaxing the bitmap traversal to allow it to produce over-counted
results gives us the opportunity to make some significant improvements.
Instead of the above, the new algorithm only has to walk from the
*boundary* down to the nearest bitmap, instead of from each of the
UNINTERESTING tips.
The boundary-based approach still has degenerate cases, but we'll show
in a moment that it is often a significant improvement.
The new algorithm works as follows:
1. Build a (partial) bitmap of the haves side by first OR-ing any
bitmap(s) that already exist for UNINTERESTING commits between the
haves and the boundary.
2. For each commit along the boundary, add it as a fill-in traversal
tip (where the traversal terminates once an existing bitmap is
found), and perform fill-in traversal.
3. Build up a complete bitmap of the wants side as usual, stopping any
time we intersect the (partial) haves side.
4. Return the results.
And is more-or-less equivalent to using the *old* algorithm with this
invocation:
$ git rev-list --objects --use-bitmap-index $WANTS --not \
$(git rev-list --objects --boundary $WANTS --not $HAVES |
perl -lne 'print $1 if /^-(.*)/')
The new result performs significantly better in many cases, particularly
when the distance from the boundary commit(s) to an existing bitmap is
shorter than the distance from (all of) the have tips to the nearest
bitmapped commit.
Note that when using the old bitmap traversal algorithm, the results can
be *slower* than without bitmaps! Under the new algorithm, the result is
computed faster with bitmaps than without (at the cost of over-counting
the true number of objects in a similar fashion as the non-bitmap
traversal):
# (Computing the number of tagged objects not on any branches
# without bitmaps).
$ time git rev-list --count --objects --tags --not --branches
20
real 0m1.388s
user 0m1.092s
sys 0m0.296s
# (Computing the same query using the old bitmap traversal).
$ time git rev-list --count --objects --tags --not --branches --use-bitmap-index

user 0m21.628s
sys 0m1.076s
# (this commit)

19
real 0m1.518s
user 0m1.234s
sys 0m0.284s
The new algorithm is still slower than not using bitmaps at all, but it
is nearly a 15-fold improvement over the existing traversal.
In a more realistic setting (using my local copy of git.git), I can
observe a similar (if more modest) speed-up:
$ argv="--count --objects --branches --not --tags"
hyperfine \
-n 'no bitmaps' "git.compile rev-list $argv" \
-n 'existing traversal' "git.compile rev-list --use-bitmap-index $argv" \
-n 'boundary traversal' "git.compile -c pack.useBitmapBoundaryTraversal=true rev-list --use-bitmap-index $argv"

Range (min … max): 166.1 ms … 169.2 ms 17 runs
Summary
'no bitmaps' ran
1.34 ± 0.02 times faster than 'boundary traversal'
2.96 ± 0.05 times faster than 'existing traversal'
Here, the new algorithm is also still slower than not using bitmaps, but
represents a more than 2-fold improvement over the existing traversal in
a more modest example.
Since this algorithm was originally written (nearly a year and a half
ago, at the time of writing), the bitmap lookup table shipped, making
the new algorithm's result more competitive. A few other future
directions for improving bitmap traversal times beyond not using bitmaps
at all:
- Decrease the cost to decompress and OR together many bitmaps
together (particularly when enumerating the uninteresting side of
the walk). Here we could explore more efficient bitmap storage
techniques, like Roaring+Run and/or use SIMD instructions to speed
up ORing them together.
- Store pseudo-merge bitmaps, which could allow us to OR together
fewer "summary" bitmaps (which would also help with the above).

To ensure compatibility, we cannot rename '--all' to another name

Sergey Organov noticed and reported "--patch --no-patch --raw"
behaves differently from just "--raw". It turns out that there are
a few interesting bugs in the implementation and documentation.
* First, the documentation for "--no-patch" was unclear that it
could be read to mean "--no-patch" countermands an earlier
"--patch" but not other things. The intention of "--no-patch"
ever since it was introduced at d09cd15d (diff: allow --no-patch
as synonym for -s, 2013-07-16) was to serve as a synonym for
"-s", so "--raw --patch --no-patch" should have produced no
output, but it can be (mis)read to allow showing only "--raw"
output.
* Then the interaction between "-s" and other format options were
poorly implemented. Modern versions of Git uses one bit each to
represent formatting options like "--patch", "--stat" in a single
output_format word, but for historical reasons, "-s" also is
represented as another bit in the same word. This allows two
interesting bugs to happen, and we have both X-<.
(1) After setting a format bit, then setting NO_OUTPUT with "-s",
the code to process another "--<format>" option drops the
NO_OUTPUT bit to allow output to be shown again. However,
the code to handle "-s" only set NO_OUTPUT without unsetting
format bits set earlier, so the earlier format bit got
revealed upon seeing the second "--<format>" option. This is
the problem Sergey observed.
(2) After setting NO_OUTPUT with "-s", code to process
"--<format>" option can forget to unset NO_OUTPUT, leaving
the command still silent.
It is tempting to change the meaning of "--no-patch" to mean
"disable only the patch format output" and reimplement "-s" as "not
showing anything", but it would be an end-user visible change in
behavior. Let's fix the interactions of these bits to first make
"-s" work as intended.
The fix is conceptually very simple.
* Whenever we set DIFF_FORMAT_FOO because we saw the "--foo"
option (e.g. DIFF_FORMAT_RAW is set when the "--raw" option is
given), we make sure we drop DIFF_FORMAT_NO_OUTPUT. We forgot to
do so in some of the options and caused (2) above.
* When processing "-s" option, we should not just set
DIFF_FORMAT_NO_OUTPUT bit, but clear other DIFF_FORMAT_* bits.
We didn't do so and retained format bits set by options
previously seen, causing (1) above.
It is even more tempting to lose NO_OUTPUT bit and instead take
output_format word being 0 as its replacement, but that would break
the mechanism "git show" uses to default to "--patch" output, where
the distinction between telling the command to be silent with "-s"
and having no output format specified on the command line matters,
and an explicit output format given on the command line should not
be "combined" with the default "--patch" format.
So, while we cannot lose the NO_OUTPUT bit, as a follow-up work, we
may want to replace it with OPTION_GIVEN bit, and
* make "--patch", "--raw", etc. set DIFF_FORMAT_$format bit and
DIFF_FORMAT_OPTION_GIVEN bit on for each format. "--no-raw",
etc. will set off DIFF_FORMAT_$format bit but still record the
fact that we saw an option from the command line by setting
DIFF_FORMAT_OPTION_GIVEN bit.
* make "-s" (and its synonym "--no-patch") clear all other bits
and set only the DIFF_FORMAT_OPTION_GIVEN bit on.
which I suspect would make the code much cleaner without breaking
any end-user expectations.
Once that is in place, transitioning "--no-patch" to mean the
counterpart of "--patch", just like "--no-raw" only defeats an
earlier "--raw", would be quite simple at the code level. The
social cost of migrating the end-user expectations might be too
great for it to be worth, but at least the "GIVEN" bit clean-up
alone may be worth it.

not freed after the processing ends. Unfortunately, the member that
points at the array, .files, is incremented as the gather_dirstat()
function recursively walks it, and this needs to be plugged by
remembering the beginning of the array before gather_dirstat() mucks
with it and freeing it after we are done.
We can mark t4047 as leak-free. t4000, which is marked as
leak-free, now can exercise dirstat in it, which will happen next.

If a filesystem-level corruption occurs in a .bitmap file, Git can react
poorly. This could take the form of a run-time error due to failing to
parse an EWAH bitmap or be more subtle such as returning the wrong set
of objects to a fetch or clone.
A natural first response to either of these kinds of errors is to run
'git fsck' to see if any files are corrupt. This currently ignores all
.bitmap files.
Add checks to 'git fsck' for all .bitmap files that are currently
associated with a multi-pack-index or pack file. Verify their checksums
using the hashfile API.
We iterate through all multi-pack-indexes and pack-files to be sure to
check all .bitmap files, not just the one that would be read by the
process. For example, a multi-pack-index bitmap overrules a pack-bitmap.
However, if the multi-pack-index is removed, the pack-bitmap may be
selected instead. Be thorough to include every file that could become
active in such a way. This includes checking files in alternates.
There is potential that we could extend this effort to check the
structure of the reachability bitmaps themselves, but it is very
expensive to do so. At minimum, it's as expensive as generating the
bitmaps in the first place, and that's assuming that we don't use the
trivial algorithm of verifying each bitmap individually. The trivial
algorithm will result in quadratic behavior (number of objects times
number of bitmapped commits) while the bitmap building operation
constructs a lattice of commits to build bitmaps incrementally and then
generate the final bitmaps from a subset of those commits.
If we were to extend 'git fsck' to check .bitmap file contents more
closely like this, then we would likely want to hide it behind an option
that signals the user is more willing to do expensive operations such as
this.
For testing, set up a repository with a pack-bitmap _and_ a
multi-pack-index bitmap. This requires some file movement to avoid
deleting the pack-bitmap during the repack that creates the
multi-pack-index bitmap. We can then verify that 'git fsck' is checking
all files, not just the "active" bitmap.

safe.bareRepository=explicit is a safer default mode of operation, since
it guards against the embedded bare repository attack [1]. Most end
users don't use bare repositories directly, so they should be able to
set safe.bareRepository=explicit, with the expectation that they can
reenable bare repositories by specifying GIT_DIR or --git-dir.
However, the user might use a tool that invokes Git on bare repositories
without setting GIT_DIR (e.g. "go mod" will clone bare repositories
[2]), so even if a user wanted to use safe.bareRepository=explicit, it
wouldn't be feasible until their tools learned to set GIT_DIR.
To make this transition easier, add a trace message to note when we
attempt to set up a bare repository without setting GIT_DIR. This allows
users and tool developers to audit which of their tools are problematic
and report/fix the issue. When they are sufficiently confident, they
would switch over to "safe.bareRepository=explicit".
Note that this uses trace2_data_string(), which isn't supported by the
"normal" GIT_TRACE2 target, only _EVENT or _PERF.

Add a test ensuring that the "wwwauth[]" field cannot be used to
inject malicious data into the credential helper stream.
Many of the credential helpers in contrib/credential read the
newline-delimited protocol stream one line at a time by repeatedly
calling fgets() into a fixed-size buffer.
This assumes that each line is no more than 1024 characters long, since
each iteration of the loop assumes that it is parsing starting at the
beginning of a new line in the stream. However, similar to a5bb10fd5e
(config: avoid fixed-sized buffer when renaming/deleting a section,
2023-04-06), if a line is longer than 1024 characters, a malicious actor
can embed another command within an existing line, bypassing the usual
checks introduced in 9a6bbee800 (credential: avoid writing values with
newlines, 2020-03-11).
As with the problem fixed in that commit, specially crafted input can
cause the helper to return the credential for the wrong host, letting an
attacker trick the victim into sending credentials for one host to
another.
Luckily, all parts of the credential helper protocol that are available
in a tagged release of Git are immune to this attack:
- "protocol" is restricted to known values, and is thus immune.
- "host" is immune because curl will reject hostnames that have a '='
character in them, which would be required to carry out this attack.
- "username" is immune, because the buffer characters to fill out the
first `fgets()` call would pollute the `username` field, causing the
credential helper to return nothing (because it would match a
username if present, and the username of the credential to be stolen
is likely not 1024 characters).
- "password" is immune because providing a password instructs
credential helpers to avoid filling credentials in the first place.
- "path" is similar to username; if present, it is not likely to match
any credential the victim is storing. It's also not enabled by
default; the victim would have to set credential.useHTTPPath
explicitly.
However, the new "wwwauth[]" field introduced via 5f2117b24f
(credential: add WWW-Authenticate header to cred requests, 2023-02-27)
can be used to inject data into the credential helper stream. For
example, running:
{
printf 'HTTP/1.1 401\r\n'
printf 'WWW-Authenticate: basic realm='
perl -e 'print "a" x 1024'
printf 'host=victim.com\r\n'
} | nc -Nlp 8080
in one terminal, and then:
git clone http://localhost:8080
in another would result in a line like:
wwwauth[]=basic realm=aaa[...]aaahost=victim.com
being sent to the credential helper. If we tweak that "1024" to align
our output with the helper's buffer size and the rest of the data on the
line, it can cause the helper to see "host=victim.com" on its own line,
allowing motivated attackers to exfiltrate credentials belonging to
"victim.com".
The below test demonstrates these failures and provides us with a test
to ensure that our fix is correct. That said, it has a couple of
shortcomings:
- it's in t0303, since that's the only mechanism we have for testing
random helpers. But that means nobody is going to run it under
normal circumstances.
- to get the attack right, it has to line up the stuffed name with the
buffer size, so we depend on the exact buffer size. I parameterized
it so it could be used to test other helpers, but in practice it's
not likely for anybody to do that.
Still, it's the best we can do, and will help us confirm the presence of
the problem (and our fixes) in the new few patches.

The comment in parse_commit_date() claims that parse_timestamp() will
not walk past the end of the buffer we've been given, since it will hit
the newline at "eol" and stop. This is usually true, when dateptr
contains actual numbers to parse. But with a line like:
committer name <email> \n
with just whitespace, and no numbers, parse_timestamp() will consume
that newline as part of the leading whitespace, and we may walk past our
"tail" pointer (which itself is set from the "size" parameter passed in
to parse_commit_buffer()).
In practice this can't cause us to walk off the end of an array, because
we always add an extra NUL byte to the end of objects we load from disk
(as a defense against exactly this kind of bug). However, you can see
the behavior in action when "committer" is the final header (which it
usually is, unless there's an encoding) and the subject line can be
parsed as an integer. We walk right past the newline on the committer
line, as well as the "\n\n" separator, and mistake the subject for the
timestamp.
We can solve this by trimming the whitespace ourselves, making sure that
it has some non-whitespace to parse. Note that we need to be a bit
careful about the definition of "whitespace" here, as our isspace()
doesn't match exotic characters like vertical tab or formfeed. We can
work around that by checking for an actual number (see the in-code
comment). This is slightly more restrictive than the current code, but
in practice the results are either the same (we reject "foo" as "0", but
so would parse_timestamp()) or extremely unlikely even for broken
commits (parse_timestamp() would allow "\v123" as "123", but we'll now
make it "0").
I did also allow "-" here, which may be controversial, as we don't
currently support negative timestamps. My reasoning was two-fold. One,
the design of parse_timestamp() is such that we should be able to easily
switch it to handling signed values, and this otherwise creates a
hard-to-find gotcha that anybody doing that work would get tripped up
on. And two, the status quo is that we currently parse them, though the
result of course ends up as a very large unsigned value (which is likely
to just get clamped to "0" for display anyway, since our date routines
can't handle it).
The new test checks the commit parser (via "--until") for both vanilla
spaces and the vertical-tab case. I also added a test to check these
against the pretty-print formatter, which uses split_ident_line(). It's
not subject to the same bug, because it already insists that there be
one or more digits in the timestamp.

To find the committer timestamp, we parse left-to-right looking for the
closing ">" of the email, and then expect the timestamp right after
that. But we've seen some broken cases in the wild where this fails, but
we _could_ find the timestamp with a little extra work. E.g.:
Name <Name<email>> 123456789 -0500
This means that features that rely on the committer timestamp, like
--since or --until, will treat the commit as happening at time 0 (i.e.,
1970).
This is doubly confusing because the pretty-print parser learned to
handle these in 03818a4a94 (split_ident: parse timestamp from end of
line, 2013-10-14). So printing them via "git show", etc, makes
everything look normal, but --until, etc are still broken (despite the
fact that that commit explicitly mentioned --until!).
So let's use the same trick as 03818a4a94: find the end of the line, and
parse back to the final ">". In theory we could use split_ident_line()
here, but it's actually a bit more strict. In particular, it requires a
valid time-zone token, too. That should be present, of course, but we
wouldn't want to break --until for cases that are working currently.
We might want to teach split_ident_line() to become more lenient there,
but it would require checking its many callers (since right now they can
assume that if date_start is non-NULL, so is tz_start).
So for now we'll just reimplement the same trick in the commit parser.
The test is in t4212, which already covers similar cases, courtesy of
03818a4a94. We'll just adjust the broken commit to munge both the author
and committer timestamps. Note that we could match (author|committer)
here, but alternation can't be used portably in sed. Since we wouldn't
expect to see ">" except as part of an ident line, we can just match
that character on any line.

Apply similar treatment as in the previous commit to remove usage of
`strtok()` from the "oidmap" test helper.
Each of the different commands that the "json-writer" helper accepts
pops the next space-delimited token from the current line and interprets
it as a string, integer, or double (with the exception of the very first
token, which is the command itself).
To accommodate this, split the line in place by the space character, and
pass the corresponding string_list to each of the specialized `get_s()`,
`get_i()`, and `get_d()` functions.
`get_i()` and `get_d()` are thin wrappers around `get_s()` that convert
their result into the appropriate type by either calling `strtol()` or
`strtod()`, respectively. In `get_s()`, we mark the token as "consumed"
by incrementing the `consumed_nr` counter, indicating how many tokens we
have read up to that point.
Because each of these functions needs the string-list parts, the number
of tokens consumed, and the line number, these three are wrapped up in
to a struct representing the line state.

Enhance `string_list_split_in_place()` to accept multiple characters as
delimiters instead of a single character.
Instead of using `strchr(2)` to locate the first occurrence of the given
delimiter character, `string_list_split_in_place_multi()` uses
`strcspn(2)` to move past the initial segment of characters comprised of
any characters in the delimiting set.
When only a single delimiting character is provided, `strpbrk(2)` (which
is implemented with `strcspn(2)`) has equivalent performance to
`strchr(2)`. Modern `strcspn(2)` implementations treat an empty
delimiter or the singleton delimiter as a special case and fall back to
calling strchrnul(). Both glibc[1] and musl[2] implement `strcspn(2)`
this way.
This change is one step to removing `strtok(2)` from the tree. Note that
`string_list_split_in_place()` is not a strict replacement for
`strtok()`, since it will happily turn sequential delimiter characters
into empty entries in the resulting string_list. For example:
string_list_split_in_place(&xs, "foo:;:bar:;:baz", ":;", -1)
would yield a string list of:
["foo", "", "", "bar", "", "", "baz"]
Callers that wish to emulate the behavior of strtok(2) more directly
should call `string_list_remove_empty_items()` after splitting.
To avoid regressions for the new multi-character delimter cases, update
t0063 in this patch as well.

similar to the way blame handles working tree contents when blaming

This is slightly confusing since this data isn't the working copy and
while it is technically "not committed yet", its also coming from an
external file. Replace this author name with "External file

key-value pairs outside of the supplied GIT_CONFIG_COUNT when trying to
produce a value for config key "pair.one".
These tests also validate that "git config" doesn't complain about
mismatched environment variables to standard error. This is validated
by redirecting the standard error to a file called "error" and asserting
that it is empty. However, two of these tests incorrectly redirect to
standard output while calling the file "error", and test 'git config
ignores pairs exceeding count' doesn't validate standard error at all.
Fix these tests by redirecting standard error to file "error" and
asserting its emptiness.

hash.h depends upon and includes repository.h, due to the definition and
use of the_hash_algo (defined as the_repository->hash_algo). However,
most headers trying to include hash.h are only interested in the layout
of the structs like object_id. Move the parts of hash.h that do not
depend upon repository.h into a new file hash-ll.h (the "low level"
parts of hash.h), and adjust other files to use this new header where
the convenience inline functions aren't needed.
This allows hash.h and object.h to be fairly small, minimal headers. It
also exposes a lot of hidden dependencies on both path.h (which was
brought in by repository.h) and repository.h (which was previously
implicitly brought in by object.h), so also adjust other files to be
more explicit about what they depend upon.

Git authentication with OAuth access token is supported by every popular
Git host including GitHub, GitLab and BitBucket [1][2][3]. Credential
helpers Git Credential Manager (GCM) and git-credential-oauth generate
OAuth credentials [4][5]. Following RFC 6749, the application prints a
link for the user to authorize access in browser. A loopback redirect
communicates the response including access token to the application.
For security, RFC 6749 recommends that OAuth response also includes
expiry date and refresh token [6]. After expiry, applications can use
the refresh token to generate a new access token without user
reauthorization in browser. GitLab and BitBucket set the expiry at two
hours [2][3]. (GitHub doesn't populate expiry or refresh token.)
However the Git credential protocol has no attribute to store the OAuth
refresh token (unrecognised attributes are silently discarded). This
means that the user has to regularly reauthorize the helper in browser.
On a browserless system, this is particularly intrusive, requiring a
second device.
Introduce a new attribute oauth_refresh_token. This is especially
useful when a storage helper and a read-only OAuth helper are configured
together. Recall that `credential fill` calls each helper until it has a
non-expired password.
```
[credential]
helper = storage # eg. cache or osxkeychain
helper = oauth
```
The OAuth helper can use the stored refresh token forwarded by
`credential fill` to generate a fresh access token without opening the
browser. See
https://github.com/hickford/git-credential-oauth/pull/3/files
for an implementation tested with this patch.
Add support for the new attribute to credential-cache. Eventually, I
hope to see support in other popular storage helpers.
Alternatives considered: ask helpers to store all unrecognised
attributes. This seems excessively complex for no obvious gain.
Helpers would also need extra information to distinguish between
confidential and non-confidential attributes.
Workarounds: GCM abuses the helper get/store/erase contract to store the
refresh token during credential *get* as the password for a fictitious
host [7] (I wrote this hack). This workaround is only feasible for a
monolithic helper with its own storage.

In check_signature(), we initialize the trust_level field to "-1", with
the idea that if gpg does not return a trust level at all (if there is
no signature, or if the signature is made by an unknown key), we'll
use that value. But this has two problems:
1. Since the field is an enum, it's up to the compiler to decide what
underlying storage to use, and it only has to fit the values we've
declared. So we may not be able to store "-1" at all. And indeed,
on my system (linux with gcc), the resulting enum is an unsigned
32-bit value, and -1 becomes 4294967295.
The difference may seem academic (and you even get "-1" if you pass
it to printf("%d")), but it means that code like this:
status |= sigc->trust_level < configured_min_trust_level;
does not necessarily behave as expected. This turns out not to be a
bug in practice, though, because we keep the "-1" only when gpg did
not report a signature from a known key, in which case the line
above:
status |= sigc->result != 'G';
would always set status to non-zero anyway. So only a 'G' signature
with no parsed trust level would cause a problem, which doesn't
seem likely to trigger (outside of unexpected gpg behavior).
2. When using the "%GT" format placeholder, we pass the value to
gpg_trust_level_to_str(), which complains that the value is out of
range with a BUG(). This behavior was introduced by 803978da49
(gpg-interface: add function for converting trust level to string,
2022-07-11). Before that, we just did a switch() on the enum, and
anything that wasn't matched would end up as the empty string.
Curiously, solving this by naively doing:
if (level < 0)
return "";
in that function isn't sufficient. Because of (1) above, the
compiler can (and does in my case) actually remove that conditional
as dead code!
We can solve both by representing this state as an enum value. We could
do this by adding a new "unknown" value. But this really seems to match
the existing "undefined" level well. GPG describes this as "Not enough
information for calculation".
We have tests in t7510 that trigger this case (verifying a signature
from a key that we don't have, and then checking various %G
placeholders), but they didn't notice the BUG() because we didn't look
at %GT for that case! Let's make sure we check all %G placeholders for
each case in the formatting tests.
The interesting ones here are "show unknown signature with custom
format" and "show lack of signature with custom format", both of which
would BUG() before, and now turn %GT into "undefined". Prior to
803978da49 they would have turned it into the empty string, but I think
saying "undefined" consistently is a reasonable outcome, and probably
makes life easier for anyone parsing the output (and any such parser had
to be ready to see "undefined" already).
The other modified tests produce the same output before and after this
patch, but now we're consistently checking both %G? and %GT in all of
them.

Back in 5b92477f89 (builtin/gc.c: conditionally avoid pruning objects
via loose, 2022-05-20), `git gc` learned the `--cruft` option and
`gc.cruftPacks` configuration to opt-in to writing cruft packs when
collecting or pruning unreachable objects.
Cruft packs were introduced with the merge in a50036da1a (Merge branch
'tb/cruft-packs', 2022-06-03). They address the problem of "loose object
explosions", where Git will write out many individual loose objects when
there is a large number of unreachable objects that have not yet aged
past `--prune=<date>`.
Instead of keeping track of those unreachable yet recent objects via
their loose object file's mtime, cruft packs collect all unreachable
objects into a single pack with a corresponding `*.mtimes` file that
acts as a table to store the mtimes of all unreachable objects. This
prevents the need to store unreachable objects as loose as they age out
of the repository, and avoids the problem of loose object explosions.
Beyond avoiding loose object explosions, cruft packs also act as a more
efficient mechanism to store unreachable objects as they age out of a
repository. This is because pairs of similar unreachable objects serve
as delta bases for one another.
In 5b92477f89, the feature was introduced as experimental. Since then,
GitHub has been running these patches in every repository generating
hundreds of millions of cruft packs along the way. The feature is
battle-tested, and avoids many pathological cases such as above. Users
who either run `git gc` manually, or via `git maintenance` can benefit
from having cruft packs.
As such, enable cruft pack generation to take place by default (by
making `gc.cruftPacks` have the default of "true" rather than "false).

In a similar fashion as previous commits, adjust the fast-import tests
to prepare for "git gc" generating a cruft pack by default.
This adjustment is slightly different, however. Instead of relying on us
writing out the objects loose, and then calling `git prune` to remove
them, t9300 needs to be prepared to drop objects that would be moved
into cruft packs.
To do this, we can combine the `git gc` invocation with `git prune` into
one `git gc --prune`, which handles pruning both loose objects, and
objects that would otherwise be written to a cruft pack.
Likely this pattern of "git gc && git prune" started all the way back in
03db4525d3 (Support gitlinks in fast-import., 2008-07-19), which
happened after deprecating `git gc --prune` in 9e7d501990 (builtin-gc.c:
deprecate --prune, it now really has no effect, 2008-05-09).
After `--prune` was un-deprecated in 58e9d9d472 (gc: make --prune useful
again by accepting an optional parameter, 2009-02-14), this script got a
handful of new "git gc && git prune" instances via via 4cedb78cb5
(fast-import: add input format tests, 2011-08-11). These could have been
`git gc --prune`, but weren't (likely taking after 03db4525d3).

Then, in c695592850 (config: let feature.experimental imply

to ensure that `feature.experimental` correctly implied enabling cruft
pack generation (or not).
These tests are similar and could be consolidated. Do so in this patch

In a similar spirit as previous commits, prepare for `gc --cruft`
becoming the default by ensuring that the tests in t6501 explicitly
cover the case of freshening loose objects not using cruft packs.
We could run this test twice, once with `--cruft` and once with
`--no-cruft`, but doing so is unnecessary, since we already test object
rescuing, freshening, and dealing with corrupt parts of the unreachable
object graph extensively via t5329.

Many of the tests in t5304 run `git gc`, and rely on its behavior that
unreachable-but-recent objects are written out loose. This is sensible,
since t5304 deals specifically with this kind of pruning.
If left unattended, however, this test would break when the default
behavior of a bare "git gc" is adjusted to generate a cruft pack by
default.
Ensure that these tests continue to work as-is (and continue to provide
coverage of loose object pruning) by passing `--no-cruft` explicitly.

When cruft packs were implemented, we never adjusted the code for `git
gc`'s `--keep-largest-pack` and `gc.bigPackThreshold` to ignore cruft
packs. This option and configuration option share a common
implementation, but including cruft packs is wrong in both cases:
- Running `git gc --keep-largest-pack` in a repository where the
largest pack is the cruft pack itself will make it impossible for
`git gc` to prune objects, since the cruft pack itself is kept.
- The same is true for `gc.bigPackThreshold`, if the size of the cruft
pack exceeds the limit set by the caller.
In the future, it is possible that `gc.bigPackThreshold` could be used
to write a separate cruft pack containing any new unreachable objects
that entered the repository since the last time a cruft pack was
written.
There are some complexities to doing so, mainly around handling
pruning objects that are in an existing cruft pack that is above the
threshold (which would either need to be rewritten, or else delay
pruning). Rewriting a substantially similar cruft pack isn't ideal, but
it is significantly better than the status-quo.
If users have large cruft packs that they don't want to rewrite, they
can mark them as `*.keep` packs. But in general, if a repository has a
cruft pack that is so large it is slowing down GC's, it should probably
be pruned anyway.
In the meantime, ignore cruft packs in the common implementation for
both of these options, and add a pair of tests to prevent any future
regressions here.

While parsing a .rev file, we check the header information to be sure it
makes sense. This happens before doing any additional validation such as
a checksum or value check. In order to differentiate between a bad
header and a non-existent file, we need to update the API for loading a
reverse index.
Make load_pack_revindex_from_disk() non-static and specify that a
positive value means "the file does not exist" while other errors during
parsing are negative values. Since an invalid header prevents setting up
the structures we would use for further validations, we can stop at that
point.
The place where we can distinguish between a missing file and a corrupt
file is inside load_revindex_from_disk(), which is used both by pack
rev-indexes and multi-pack-index rev-indexes. Some tests in t5326
demonstrate that it is critical to take some conditions to allow
positive error signals.
Add tests that check the three header values.

The 'fsck' builtin checks many of Git's on-disk data structures, but
does not currently validate the pack rev-index files (a .rev file to
pair with a .pack and .idx file).
Before doing a more-involved check process, create the scaffolding
within builtin/fsck.c to have a new error type and add that error type
when the API method verify_pack_revindex() returns an error. That method
does nothing currently, but we will add checks to it in later changes.
For now, check that 'git fsck' succeeds without any errors in the normal
case. Future checks will be paired with tests that corrupt the .rev file
appropriately.
