After a38edab7c8 (Makefile: generate doc versions via GIT-VERSION-GEN,
2024-12-06), we no longer inject GIT_DATE when building with
Asciidoctor.
Replace the <date/> tag in the XML to inject the value of GIT_DATE.
Unlike <refmiscinfo/> as handled in a recent commit, we have no reason
to expect that this tag might be missing, so there's no need for "maybe
remove, then add" and we can just outright replace the one that
Asciidoctor has generated based on the mtime of the source file.
Compared to pre-a38edab7c8, we now end up injecting this also in the
build of Git.3pm, which until now has been using the mtime of Git.pm.
That is arguably even a good change since it results in more
reproducible builds.

Commit a38edab7c8 (Makefile: generate doc versions via GIT-VERSION-GEN,
2024-12-06) stopped providing an attribute value "Git $(GIT_VERSION)" to
asciidoc/Asciidoctor over the command line. Instead, we now provide the
attribute to asciidoc through a generated asciidoc.conf, where the value
is generated as "Git @GIT_VERSION@".
In the similar mechanism for Asciidoctor, we forgot the "Git" prefix.
Restore it.

After the recent a38edab7c8 (Makefile: generate doc versions via
GIT-VERSION-GEN, 2024-12-06), building with Asciidoctor results in
manpages where the headers no longer contain "Git Manual" and the
footers no longer identify the built Git version.
Before a38edab7c8, we used to just provide a few attributes to
Asciidoctor (and asciidoc). Commit 7a30134358 (asciidoctor-extensions:
provide `<refmiscinfo/>`, 2019-09-16) noted that older versions of
Asciidoctor didn't propagate those attributes into the built XML files,
so we started injecting them ourselves from this script. With newer
versions of Asciidoctor, we'd end up with some harmless duplication
among the tags in the final XML.
Post-a38edab7c8, we don't provide these attributes and Asciidoctor
inserts empty-ish values. After our additions from 7a30134358, we get
<refmiscinfo class="source"> </refmiscinfo>
<refmiscinfo class="manual"> </refmiscinfo>
<refmiscinfo class="source">2.47.1.[...]</refmiscinfo>
<refmiscinfo class="manual">Git Manual</refmiscinfo>
When these are handled, it appears to be first come first served,
meaning that our additions have no effect and we regress as described in
the first paragraph.
Remove existing "source" or "manual" <refmiscinfo/> tags before adding
ours. I considered removing all <refmiscinfo/> to get a nice clean
slate, instead of just those two that we want to replace to be a bit
more precise. I opted for the latter. Maybe one day, Asciidoctor learns
to insert something useful there which `xmlto` can pick up and make good
use of -- let's not interfere.

Same as with the preceding commit, neither GIT_BUILT_FROM_COMMIT nor
GIT_DATE can be overridden via the environment. Especially the latter is
of importance given that we set it in our own "Documentation/doc-diff"

GIT-VERSION-GEN tries to derive the version that Git is being built from
via multiple different sources in the following order:
1. A file called "version" in the source tree's root directory, if it
exists.
2. The current commit in case Git is built from a Git repository.
3. Otherwise, we use a fallback version stored in a variable which is
bumped whenever a new Git version is getting tagged.
It used to be possible to override the version by overriding the
`GIT_VERSION` Makefile variable (e.g. `make GIT_VERSION=foo`). This
worked somewhat by chance, only: `GIT-VERSION-GEN` would write the
actual Git version into `GIT-VERSION-FILE`, not the overridden value,
but when including the file into our Makefile we would not override the
`GIT_VERSION` variable because it has already been set by the user. And
because our Makefile used the variable to propagate the version to our
build tools instead of using `GIT-VERSION-FILE` the resulting build
artifacts used the overridden version.
But that subtle mechanism broke with 4838deab65 (Makefile: refactor
GIT-VERSION-GEN to be reusable, 2024-12-06) and subsequent commits
because the version information is not propagated via the Makefile
variable anymore, but instead via the files that `GIT-VERSION-GEN`
started to write. And as the script never knew about the `GIT_VERSION`
environment variable in the first place it uses one of the values listed
above instead of the overridden value.
Fix this issue by making `GIT-VERSION-GEN` handle the case where
`GIT_VERSION` has been set via the environment.
Note that this requires us to introduce a new GIT_VERSION_OVERRIDE
variable that stores a potential user-provided value, either via the
environment or via "config.mak". Ideally we wouldn't need it and could
just continue to use GIT_VERSION for this. But unfortunately, Makefiles
will first include all sub-Makefiles before figuring out whether it
needs to re-make any of them [1]. Consequently, if there already is a
GIT-VERSION-FILE, we would have slurped in its value of GIT_VERSION
before we call GIT-VERSION-GEN, and because GIT-VERSION-GEN now uses
that value as an override it would mean that the first generated value
for GIT_VERSION will remain unchanged.
Furthermore we have to move the include for "GIT-VERSION-FILE" after the
includes for "config.mak" and related so that GIT_VERSION_OVERRIDE can
be set to the value provided by "config.mak".

Some of the callsites of GIT-VERSION-GEN generate the target file with a
"+" suffix first and then move the file into place when the new contents
are different compared to the old contents. This allows us to avoid a
needless rebuild by not updating timestamps of the target file when its
contents will remain unchanged anyway.
In fact though, this exact logic is already handled in GIT-VERSION-GEN,
so doing this manually is pointless. This is a leftover from an earlier
version of 4838deab65 (Makefile: refactor GIT-VERSION-GEN to be
reusable, 2024-12-06), where the script didn't handle that logic for us.

It is possible to configure a Git build without Perl when disabling both
our test suite and all Perl-based features. In Meson, this can be
achieved with `meson setup -Dperl=disabled -Dtests=false`.
It was reported by a user that this breaks the Meson build because
gitweb gets built even if Perl was not discovered in such a build:
$ meson setup .. -Dtests=false -Dperl=disabled
...
../gitweb/meson.build:2:43: ERROR: Unable to get the path of a not-found external program
Fix this issue by introducing a new feature-option that allows the user
to configure whether or not to build Gitweb. The feature is set to
'auto' by default and will be disabled automatically in case Perl was
not found on the system.

The path-walk API currently uses a stack-based approach to recursing
through the list of paths within the repository. This guarantees that
after a tree path is explored, all paths contained within that tree path
will be explored before continuing to explore siblings of that tree
path.
The initial motivation of this depth-first approach was to minimize
memory pressure while exploring the repository. A breadth-first approach
would have too many "active" paths being stored in the paths_to_lists
map.
We can take this approach one step further by making sure that blob
paths are visited before tree paths. This allows the API to free the
memory for these blob objects before continuing to perform the
depth-first search. This modifies the order in which we visit siblings,
but does not change the fact that we are performing depth-first search.
To achieve this goal, use a priority queue with a custom sorting method.
The sort needs to handle tags, blobs, and trees (commits are handled
slightly differently). When objects share a type, we can sort by path
name. This will keep children of the latest path to leave the stack be
preferred over the rest of the paths in the stack, since they agree in
prefix up to and including a directory separator. When the types are
different, we can prefer tags over other types and blobs over trees.
This causes significant adjustments to t6601-path-walk.sh to rearrange
the order of the visited paths.

When the input rev_info has UNINTERESTING starting points, we want to be
sure that the UNINTERESTING flag is passed appropriately through the
objects. To match how this is done in places such as 'git pack-objects', we
use the mark_edges_uninteresting() method.
This method has an option for using the "sparse" walk, which is similar in
spirit to the path-walk API's walk. To be sure to keep it independent, add a
new 'prune_all_uninteresting' option to the path_walk_info struct.
To check how the UNINTERSTING flag is spread through our objects, extend the
'test-tool path-walk' command to output whether or not an object has that
flag. This changes our tests significantly, including the removal of some
objects that were previously visited due to the incomplete implementation.

The rev_info that is specified for a path-walk traversal may specify
visiting tag refs (both lightweight and annotated) and also may specify
indexed objects (blobs and trees). Update the path-walk API to walk
these objects as well.
When walking tags, we need to peel the annotated objects until reaching
a non-tag object. If we reach a commit, then we can add it to the
pending objects to make sure we visit in the commit walk portion. If we
reach a tree, then we will assume that it is a root tree. If we reach a
blob, then we have no good path name and so add it to a new list of
"tagged blobs".
When the rev_info includes the "--indexed-objects" flag, then the
pending set includes blobs and trees found in the cache entries and
cache-tree. The cache entries are usually blobs, though they could be
trees in the case of a sparse index. The cache-tree stores
previously-hashed tree objects but these are cleared out when staging
objects below those paths. We add tests that demonstrate this.
The indexed objects come with a non-NULL 'path' value in the pending
item. This allows us to prepopulate the 'path_to_lists' strmap with
lists for these paths.
The tricky thing about this walk is that we will want to combine the
indexed objects walk with the commit walk, especially in the future case
of walking objects during a command like 'git repack'.
Whenever possible, we want the objects from the index to be grouped with
similar objects in history. We don't want to miss any paths that appear
only in the index and not in the commit history.
Thus, we need to be careful to let the path stack be populated initially
with only the root tree path (and possibly tags and tagged blobs) and go
through the normal depth-first search. Afterwards, if there are other
paths that are remaining in the paths_to_lists strmap, we should then
iterate through the stack and visit those objects recursively.

We add the ability to filter the object types in the path-walk API so
the callback function is called fewer times.
This adds the ability to ask for the commits in a list, as well. We
re-use the empty string for this set of objects because these are passed
directly to the callback function instead of being part of the
'path_stack'.
Future changes will add the ability to visit annotated tags.

Add some tests based on the current behavior, doing interesting checks
for different sets of branches, ranges, and the --boundary option. This
sets a baseline for the behavior and we can extend it as new options are
introduced.
Store and output a 'batch_nr' value so we can demonstrate that the paths are
grouped together in a batch and not following some other ordering. This
allows us to test the depth-first behavior of the path-walk API. However, we
purposefully do not test the order of the objects in the batch, so the
output is compared to the expected output through a sort.
It is important to mention that the behavior of the API will change soon as
we start to handle UNINTERESTING objects differently, but these tests will
demonstrate the change in behavior.

In anticipation of a few planned applications, introduce the most basic form
of a path-walk API. It currently assumes that there are no UNINTERESTING
objects, and does not include any complicated filters. It calls a function
pointer on groups of tree and blob objects as grouped by path. This only
includes objects the first time they are discovered, so an object that
appears at multiple paths will not be included in two batches.
These batches are collected in 'struct type_and_oid_list' objects, which
store an object type and an oid_array of objects.
The data structures are documented in 'struct path_walk_context', but in
summary the most important are:
* 'paths_to_lists' is a strmap that connects a path to a
type_and_oid_list for that path. To avoid conflicts in path names,
we make sure that tree paths end in "/" (except the root path with
is an empty string) and blob paths do not end in "/".
* 'path_stack' is a string list that is added to in an append-only
way. This stores the stack of our depth-first search on the heap
instead of using recursion.
* 'path_stack_pushed' is a strmap that stores path names that were
already added to 'path_stack', to avoid repeating paths in the
stack. Mostly, this saves us from quadratic lookups from doing
unsorted checks into the string_list.
The coupling of 'path_stack' and 'path_stack_pushed' is protected by the
push_to_stack() method. Call this instead of inserting into these
structures directly.
The walk_objects_by_path() method initializes these structures and
starts walking commits from the given rev_info struct. The commits are
used to find the list of root trees which populate the start of our
depth-first search.
The core of our depth-first search is in a while loop that continues
while we have not indicated an early exit and our 'path_stack' still has
entries in it. The loop body pops a path off of the stack and "visits"
the path via the walk_path() method.
The walk_path() method gets the list of OIDs from the 'path_to_lists'
strmap and executes the callback method on that list with the given path
and type. If the OIDs correspond to tree objects, then iterate over all
trees in the list and run add_children() to add the child objects to
their own lists, adding new entries to the stack if necessary.
In testing, this depth-first search approach was the one that used the
least memory while iterating over the object lists. There is still a
chance that repositories with too-wide path patterns could cause memory
pressure issues. Limiting the stack size could be done in the future by
limiting how many objects are being considered in-progress, or by
visiting blob paths earlier than trees.
There are many future adaptations that could be made, but they are left for
future updates when consumers are ready to take advantage of those features.

The alloc and nr fields of a prio-queue tell us how much memory is
allocated and used in the array. So the natural type for them is size_t,
which prevents overflow on 64-bit systems where "int" is still 32 bits.
This is unlikely to happen in practice, as we typically use it for
storing commits, and having 2^31 of those is rather a lot. But it's good
to keep our generic data structures as flexible as possible. And as we
start to enforce -Wsign-compare, it means that callers need to use
"int", too, and the problem proliferates. Let's fix it at the source.
The changes here can be put into a few groups:
1. Changing the alloc/nr fields in the struct to size_t. This requires
swapping out int for size_t in negotiator/skipping.c, as well as
in prio_queue_get(), because those all iterate over the array.
Building with -Wsign-compare complains about these.
2. Other code that assigns or passes around indexes into the array
(e.g., the swap() and compare() functions) won't trigger
-Wsign-compare because we are simply truncating the values. These
are caught by -Wconversion, but I've adjusted them here to
future-proof us.
3. In prio_queue_reverse() we compute "queue->nr - 1" without checking
if anything is in the queue, which underflows now that nr is
unsigned. We can fix that by returning early when the queue is
empty (there is nothing to reverse).
4. The insertion_ctr variable is currently unsigned, but can likewise
grow (it is actually worse, because adding and removing an element
many times will keep increasing the counter, even though "nr" does
not). I've bumped that to size_t here, as well.
But -Wconversion notes that computing the "cmp" result by
subtracting the counters and assigning to "int" is a potential
problem. And that's true even before this patch, since we use an
unsigned counter (imagine comparing "2^32-1" and "0", which should
be a high positive value, but instead is "-1" as a signed int).
Since we only care about the sign (and not the magnitude) of the
result, we could fix this by swapping out the subtraction for a
ternary comparison. Probably the performance impact would be
negligible, since we just called into a custom compare function and
branched on its result anyway. But it's easy enough to do a
branchless version by subtracting the comparison results.

Commit 44f9fd6496 (pack-bitmap.c: check preferred pack validity when
opening MIDX bitmap, 2022-05-24) prevents a race condition whereby the
preferred pack disappears between opening the MIDX bitmap and attempting
verbatim reuse out of its packs.
That commit forces open_midx_bitmap_1() to ensure the validity of the
MIDX's preferred pack, meaning that we have an open file handle on the
*.pack, ensuring that we can reuse bytes out of verbatim later on in the
process[^1].
But 44f9fd6496 was not extended to cover multi-pack reuse, meaning that
this same race condition exists for non-preferred packs during verbatim
reuse. Work around that race in the same way by only marking valid packs
as reuse-able. For packs that aren't reusable, skip over them but
include the number of objects they have to ensure we allocate a large
enough 'reuse' bitmap (e.g. if a pack in the middle of the MIDX
disappeared but we still want to reuse later packs).
Since we're ensuring the validity of these packs within the verbatim
reuse code, we no longer have to special-case the preferred pack and
open it within the open_midx_bitmap_1() function.
An alternative approach to the one taken here would be to open all
MIDX'd packs from within open_midx_bitmap_1(). But that would be both
slower and make the bitmaps less useful, since we can still perform some
pack reuse among the packs that still exist when the *.bitmap is opened.
After applying this patch, we can simulate the new behavior after
instrumenting Git like so:
diff --git a/packfile.c b/packfile.c
index 9560f0a33c..aedce72524 100644

Note that we could relax the single-pack version of this which was most
recently addressed in dc1daacdcc (pack-bitmap: check pack validity when
opening bitmap, 2021-07-23), but only partially. Because we still need
to know the object count in the pack, we'd still have to open the pack's
*.idx, so the savings there are marginal.
Note likewise that we add a new "if (!packs_nr)" early return in the
pack reuse code to avoid a potentially expensive allocation on the
'reuse' bitmap in the case that no packs are available for reuse.
[^1]: Unless we run out of open file handles. If that happens and we are
forced to close the only open file handle of a file that has been
removed from underneath us, there is nothing we can do.

When the `vcxproj` target was introduced in `config.mak.uname` to allow
building Git with the Visual C toolchain, the `git remote-ext` command
was always executed in its dashed form. Therefore, it was impossible to
pass the test suite unless that command existed in its dashed form, and
we had to special-case this.
Later, when the `vcxproj` target got out of fashion because Visual
Studio gained native support for CMake builds, this special-casing was
copied without questioning it.
But as of 675df192c5f (transport-helper: do not run git-remote-ext etc.
in dashed form, 2020-08-26), the reason for this special-casing no
longer exists. So let's just drop it.
