The unnecessary include in the header transitively pulled in some
other headers actually needed by source files, though. Have those
source files explicitly include the headers they need.

Use the commit color instead of the HEAD color for the arrow or custom
symbol in "HEAD -> branch" decorations, for visual consistency with the
prefix, separator and suffix symbols, which are also colored with the
commit color.
This change was triggered by the possibility that one could choose to
use the same symbol for the pointer and the separator options in
%(decorate), in which case they ought to be the same color.
A related precedent is 'ls -l', where the arrow for symlinks gets the
default color rather than that of the symlink name.
Amend test t4207-log-decoration-colors.sh accordingly.

Add pointer and tag options to %(decorate) format, to allow to override

used to mark tags.

Wrap "tag:" prefixes and the arrows in "HEAD -> branch" decorations in
their own color sequences. Otherwise, if --graph is used, tag names or
arrows can end up uncolored when %w width formatting breaks a line just
before them. This is because --graph resets the color after doing its
drawing at the start of a line.

Rename the format_decorations_extended function to format_decorations
and drop the format_decorations wrapper macro. Pass the prefix, suffix
and separator strings as a single 'struct format_decorations' pointer
argument instead of separate arguments. Use default values defined in
the function when either the struct pointer or any of the struct fields
are NULL. This is to ease extension with additional options.

The vast majority of files including object-store.h did not need dir.h
nor khash.h. Split the header into two files, and let most just depend
upon object-store-ll.h, while letting the two callers that need it
depend on the full object-store.h.
After this patch:
$ git grep -h include..object-store | sort | uniq -c

129 #include "object-store-ll.h"

The include of wildmatch.h in git-compat-util.h was added in cebcab189aa
(Makefile: add USE_WILDMATCH to use wildmatch as fnmatch, 2013-01-01) as
a way to be able to compile-time force any calls to fnmatch() to instead
invoke wildmatch(). The defines and inline function were removed in
70a8fc999d9 (stop using fnmatch (either native or compat), 2014-02-15),
and this include in git-compat-util.h has been unnecessary ever since.
Remove the include from git-compat-util.h, but add it to the .c files
that had omitted the direct #include they needed.

The 'read_replace_objects' constant is initialized by git_default_config
(if core.useReplaceRefs is disabled) and within setup_git_env (if
GIT_NO_REPLACE_OBJECTS) is set. To ensure that this variable cannot be
set accidentally in other places, wrap it in a replace_refs_enabled()
method.
Since we still assign this global in config.c, we are not able to remove
the global scope of this variable and make it a static within
replace-object.c. This will happen in a later change which will also
prevent the variable from being read before it is initialized.
Centralizing read access to the variable is an important first step.

We used to write "Message-Id:" and "Message-ID:" pretty much
interchangeably, and the header name is defined to be case
insensitive by the RFCs, but the canonical form "Message-ID:" is
used throughout the RFC documents, so let's imitate it ourselves.

git-compat-util: add UNUSED macro
|
|
As reported in [1] the "UNUSED(var)" macro introduced in
2174b8c75de (Merge branch 'jk/unused-annotation' into next,
2022-08-24) breaks coccinelle's parsing of our sources in files where
it occurs.
Let's instead partially go with the approach suggested in [2] of
making this not take an argument. As noted in [1] "coccinelle" will
ignore such tokens in argument lists that it doesn't know about, and
it's less of a surprise to syntax highlighters.
This undoes the "help us notice when a parameter marked as unused is
actually use" part of 9b240347543 (git-compat-util: add UNUSED macro,
2022-08-19), a subsequent commit will further tweak the macro to
implement a replacement for that functionality.

This function has never used its "commit" parameter since it was added
in db757e8b8d (show, log: provide a --remerge-diff capability,
2022-02-02).
This makes sense; we already have separate parameters for the parents
(which lets us redo the merge) and the oid of the result tree (which we
can then diff against the remerge result).
Let's drop the unused parameter in the name of clarity.

The add_ref_decoration() method uses an if/else-if chain to determine if
a ref matches a known ref namespace that has a special decoration
category. That decoration type is later used to assign a color when
writing to stdout.
The newly-added ref_namespaces array contains all namespaces, along
with information about their decoration type. Check this array instead
of this if/else-if chain. This reduces our dependency on string literals
being embedded in the decoration logic.

The ref_namespaces array is a new centralized location for information

"diff-tree --stdin" has been broken for about a year, but 2.36
release broke it even worse by breaking running the command with
<pathspec>, which in turn broke "gitk" and got noticed. This has
been corrected by aligning its behaviour to that of "log".
* jc/diff-tree-stdin-fix:
2.36 gitk/diff-tree --stdin regression fix
|
|
This only surfaced as a regression after 2.36 release, but the
breakage was already there with us for at least a year.
The diff_free() call is to be used after we completely finished with
a diffopt structure. After "git diff A B" finishes producing
output, calling it before process exit is fine. But there are
commands that prepares diff_options struct once, compares two sets
of paths, releases resources that were used to do the comparison,
then reuses the same diff_option struct to go on to compare the next
two sets of paths, like "git log -p".
After "git log -p" finishes showing a single commit, calling it
before it goes on to the next commit is NOT fine. There is a
mechanism, the .no_free member in diff_options struct, to help "git
log" to avoid calling diff_free() after showing each commit and
instead call it just one. When the mechanism was introduced in
e900d494 (diff: add an API for deferred freeing, 2021-02-11),
however, we forgot to do the same to "diff-tree --stdin", which *is*
a moral equivalent to "git log".
During 2.36 release cycle, we started clearing the pathspec in
diff_free(), so programs like gitk that runs
git diff-tree --stdin -- <pathspec>
downstream of a pipe, processing one commit after another, started
showing irrelevant comparison outside the given <pathspec> from the
second commit. The same commit, by forgetting to teach the .no_free
mechanism, broke "diff-tree --stdin -I<regexp>" and nobody noticed
it for over a year, presumably because it is so seldom used an
option.
But <pathspec> is a different story. The breakage was very
prominently visible and was reported immediately after 2.36 was
released.
Fix this breakage by mimicking how "git log" utilizes the .no_free
member so that "diff-tree --stdin" behaves more similarly to "log".
Protect the fix with a few new tests.

Change the hash_object_file() function to take an "enum

Since a preceding commit all of its callers are passing either
"{commit,tree,blob,tag}_type", or the result of a call to type_name(),
the parse_object() caller that would pass NULL is now using
stream_object_signature().

The --remerge-diff option will need to create new blobs and trees
representing the "automatic merge" state. If one is traversing a
long project history, one can easily get hundreds of thousands of
loose objects generated during `log --remerge-diff`. However, none of
those loose objects are needed after we have completed our diff
operation; they can be summarily deleted.
Add a new helper function to tmp_objdir to discard all the contained
objects, and call it after each merge is handled.
