Add 'gitglossary' definitions for "dereference" (as it used for both symrefs
and objects) and "peel". These terms are used in options and documentation
throughout Git, but they are not clearly defined anywhere and the behavior
they refer to depends heavily on context. Provide explicit definitions to
clarify existing documentation to users and help contributors to use the
most appropriate terminology possible in their additions to Git.
Update other definitions in the glossary that use the term "dereference" to
link to 'def_dereference'.

When performing revision queries with `--objects` and
`--use-bitmap-index`, the output may incorrectly contain objects which
are packed, even when the `--unpacked` option is given. This affects
traversals, but also other querying operations, like `--count`,
`--disk-usage`, etc.
Like in the previous commit, the fix is to exclude those objects from
the result set before they are shown to the user (or, in this case,
before the bitmap containing the result of the traversal is enumerated
and its objects listed).
This is performed by a new function in pack-bitmap.c, called
`filter_packed_objects_from_bitmap()`. Note that we do not have to
inspect individual bits in the result bitmap, since we know that the
first N (where N is the number of objects in the bitmap's pack/MIDX)
bits correspond to objects which packed by definition.
In other words, for an object to have a bitmap position (not in the
extended index), it must appear in either the bitmap's pack or one of
the packs in its MIDX.
This presents an appealing optimization to us, which is that we can
simply memset() the corresponding number of `eword_t`'s to zero,
provided that we handle any objects which spill into the next word (but
don't occupy all 64 bits of the word itself).
We only have to handle objects in the bitmap's extended index. These
objects may (or may not) appear in one or more pack(s). Since these
objects are known to not appear in either the bitmap's MIDX or pack,
they may be stored as loose, appear in other pack(s), or both.
Before returning a bitmap containing the result of the traversal back to
the caller, drop any bits from the extended index which appear in one or
more packs. This implements the correct behavior for rev-list operations
which use the bitmap index to compute their result.

In git-rev-list(1), we describe the `--unpacked` option as:
Only useful with `--objects`; print the object IDs that are not in
packs.
This is true of commits, which we discard via get_commit_action(), but
not of the objects they reach. So if we ask for an --objects traversal
with --unpacked, we may get arbitrarily many objects which are indeed
packed.
I am nearly certain this behavior dates back to the introduction of
`--unpacked` via 12d2a18780 ("git rev-list --unpacked" shows only
unpacked commits, 2005-07-03), but I couldn't get that revision of Git
to compile for me. At least as early as v2.0.0 this has been subtly
broken:
$ git.compile --version
git version 2.0.0
$ git.compile rev-list --objects --all --unpacked
72791fe96c93f9ec5c311b8bc966ab349b3b5bbe
05713d991c18bbeef7e154f99660005311b5004d v1.0
153ed8b7719c6f5a68ce7ffc43133e95a6ac0fdb
8e4020bb5a8d8c873b25de15933e75cc0fc275df one
9200b628cf9dc883a85a7abc8d6e6730baee589c two
3e6b46e1b7e3b91acce99f6a823104c28aae0b58 unpacked.t
There, only the first, third, and sixth entries are loose, with the
remaining set of objects belonging to at least one pack.
The implications for this are relatively benign: bare 'git repack'
invocations which invoke pack-objects with --unpacked are impacted, and
at worst we'll store a few extra objects that should have been excluded.
Arguably changing this behavior is a backwards-incompatible change,
since it alters the set of objects emitted from rev-list queries with
`--objects` and `--unpacked`. But I argue that this change is still
sensible, since the existing implementation deviates from
clearly-written documentation.
The fix here is straightforward: avoid showing any non-commit objects
which are contained in packs by discarding them within list-objects.c,
before they are shown to the user. Note that similar treatment for
`list-objects.c::show_commit()` is not needed, since that case is
already handled by `revision.c::get_commit_action()`.

The `upgrade_repository_format()` function has multiple exit paths,
which means that there is no common cleanup of acquired resources.
While this isn't much of a problem right now, we're about to fix a
memory leak that would require us to free the resource in every one of
those exit paths.
Refactor the code to have a common exit path so that the subsequent
memory leak fix becomes easier to implement.

We're setting up the Git directory twice in the `test-tool bloom`
helper, once at the beginning of `cmd_bloom()` and once in the local
subcommand implementation `get_bloom_filter_for_commit()`. This can lead
to memory leaks as we'll overwrite variables of `the_repository` with
newly allocated data structures. On top of that it's simply unnecessary.
Fix this by only setting up the Git directory once.

The perl script introduced by 86b008ee61 (t: add library for munging
chunk-format files, 2023-10-09) uses pack("Q") and unpack("Q") to read
and write 64-bit values ("quadwords" in perl parlance) from the on-disk
chunk files. However, some builds of perl may not support 64-bit
integers at all, and throw an exception here. While some 32-bit
platforms may still support 64-bit integers in perl (such as our linux32
CI environment), others reportedly don't (the NonStop 32-bit builds).
We can work around this by treating the 64-bit values as two 32-bit
values. We can't ever combine them into a single 64-bit value, but in
practice this is OK. These are representing file offsets, and our files
are much smaller than 4GB. So the upper half of the 64-bit value will
always be 0.
We can just introduce a few helper functions which perform the
translation and double-check our assumptions.

In April, GitHub announced that the `macos-13` pool is available:
https://github.blog/changelog/2023-04-24-github-actions-macos-13-is-now-available/.
It is only a matter of time until the `macos-12` pool is going away,
therefore we should switch now, without pressure of a looming deadline.
Since the `macos-13` runners no longer include Python2, we also drop
specifically testing with Python2 and switch uniformly to Python3, see
https://github.com/actions/runner-images/blob/HEAD/images/macos/macos-13-Readme.md
for details about the software available on the `macos-13` pool's
runners.
Also, on macOS 13, Homebrew seems to install a `gcc@9` package that no
longer comes with a regular `unistd.h` (there seems only to be a
`ssp/unistd.h`), and hence builds would fail with:
In file included from base85.c:1:
git-compat-util.h:223:10: fatal error: unistd.h: No such file or directory
223 | #include <unistd.h>
| ^~~~~~~~~~
compilation terminated.
The reason why we install GCC v9.x explicitly is historical, and back in
the days it was because it was the _newest_ version available via
Homebrew: 176441bfb58 (ci: build Git with GCC 9 in the 'osx-gcc' build
job, 2019-11-27).
To reinstate the spirit of that commit _and_ to fix that build failure,
let's switch to the now-newest GCC version: v13.x.

They are equivalents and the former still exists, so as long as the
only change this commit makes are to rewrite test_i18ngrep to
test_grep, there won't be any new bug, even if there still are
callers of test_i18ngrep remaining in the tree, or when merged to
other topics that add new uses of test_i18ngrep.
This patch was produced more or less with
git grep -l -e 'test_i18ngrep ' 't/t[0-9][0-9][0-9][0-9]-*.sh' |
xargs perl -p -i -e 's/test_i18ngrep /test_grep /'
and a good way to sanity check the result yourself is to run the
above in a checkout of c4603c1c (test framework: further deprecate
test_i18ngrep, 2023-10-31) and compare the resulting working tree
contents with the result of applying this patch to the same commit.
You'll see that test_i18ngrep in a few t/lib-*.sh files corrected,
in addition to the manual reproduction.

There seems to be some internal stack overflow detection in MSVC's
`malloc()` machinery that seems to be independent of the `stack reserve`
and `heap reserve` sizes specified in the executable (editable via
`EDITBIN /STACK:<n> <exe>` and `EDITBIN /HEAP:<n> <exe>`).
In the newly test cases added by `jk/tree-name-and-depth-limit`, this
stack overflow detection is unfortunately triggered before Git can print
out the error message about too-deep trees and exit gracefully. Instead,
it exits with `STATUS_STACK_OVERFLOW`. This corresponds to the numeric
value -1073741571, something the MSYS2 runtime we sadly need to use to
run Git's test suite cannot handle and which it internally maps to the
exit code 127. Git's test suite, in turn, mistakes this to mean that the
command was not found, and fails both test cases.

I verified manually that `traverse_trees_cur_depth` was 562 when that
happened, which is far below the 2048 that were already accepted into
Git as a hard limit.
Despite many attempts to figure out which of the internals trigger this
`STATUS_STACK_OVERFLOW` and how to maybe increase certain sizes to avoid
running into this issue and let Git behave the same way as under Linux,
I failed to find any build-time/runtime knob we could turn to that
effect.
Note: even switching to using a different allocator (I used mimalloc
because that's what Git for Windows uses for its GCC builds) does not
help, as the zlib code used to unpack compressed pack entries _still_
uses the regular `malloc()`. And runs into the same issue.
Note also: switching to using a different allocator _also_ for zlib code
seems _also_ not to help. I tried that, and it still exited with
`STATUS_STACK_OVERFLOW` that seems to have been triggered by a
`mi_assert_internal()`, i.e. an internal assertion of mimalloc...
So the best bet to work around this for now seems to just lower the
maximum allowed tree depth _even further_ for MSVC builds.

git merge-file knows how to merge files on the file system already. It
would be helpful, however, to allow it to also merge single blobs.
Teach it an `--object-id` option which means that its arguments are
object IDs and not files to allow it to do so.
We handle the empty blob specially since read_mmblob doesn't read it
directly and otherwise users cannot specify an empty ancestor.

`git merge-file` takes three positional arguments. Each of them is
documented as `<foo-file>`. In preparation for teaching this command to
alternatively take three object IDs, make these placeholders a bit more
generic by dropping the "-file" parts. Instead, clarify early that the
three arguments are filenames. Even after the next commit, we can afford
to present this file-centric view up front and in the general
discussion, since it will remain the default one.

Back in 32f3c541e3 (multi-pack-index: write pack names in chunk,
2018-07-12) the MIDX's "Packfile Names" (or "PNAM", for short) chunk was
described as containing an array of string entries. e0d1bcf825 notes
that this is the only chunk in the MIDX format's specification that is
not guaranteed to be 4-byte aligned, and so should be placed last.
This isn't quite accurate: the entries within the PNAM chunk are not
guaranteed to be 4-byte aligned since they are arbitrary strings, but
the chunk itself is 4-byte aligned since the ending is padded with NUL
bytes.
That padding has always been there since 32f3c541e3 via
midx.c::write_midx_pack_names(), which ended with:
i = MIDX_CHUNK_ALIGNMENT - (written % MIDX_CHUNK_ALIGNMENT)
if (i < MIDX_CHUNK_ALIGNMENT) {
unsigned char padding[MIDX_CHUNK_ALIGNMENT];
memset(padding, 0, sizeof(padding))
hashwrite(f, padding, i);
written += i;
}
In fact, 32f3c541e3's log message itself describes the chunk in its
first paragraph with:
Since filenames are not well structured, add padding to keep good
alignment in later chunks.
So these have always been externally aligned. Correct the corresponding
part of our documentation to reflect that.

e0d1bcf825 (multi-pack-index: add format details, 2018-07-12) describes
the MIDX's "PNAM" chunk as having entries which are "null-terminated
strings".
This is a typo, as strings are terminated with a NUL character, which is
a distinct concept from "NULL" or "null", which we typically reserve for
the void pointer to address 0.
Correct the documentation accordingly.

Convert tests that use `test_path_is_file` and `test_path_is_missing` to
instead use a set of helpers `test_ref_exists` and `test_ref_missing`.

While we have multiple ways to show the value of a given reference, we
do not have any way to check whether a reference exists at all. While
commands like git-rev-parse(1) or git-show-ref(1) can be used to check
for reference existence in case the reference resolves to something
sane, neither of them can be used to check for existence in some other
scenarios where the reference does not resolve cleanly:
- References which have an invalid name cannot be resolved.
- References to nonexistent objects cannot be resolved.
- Dangling symrefs can be resolved via git-symbolic-ref(1), but this
requires the caller to special case existence checks depending on
whether or not a reference is symbolic or direct.
Furthermore, git-rev-list(1) and other commands do not let the caller
distinguish easily between an actually missing reference and a generic
error.
Taken together, this seems like sufficient motivation to introduce a
separate plumbing command to explicitly check for the existence of a
reference without trying to resolve its contents.
This new command comes in the form of `git show-ref --exists`. This
new mode will exit successfully when the reference exists, with a
specific exit code of 2 when it does not exist, or with 1 when there
has been a generic error.
Note that the only way to properly implement this command is by using
the internal `refs_read_raw_ref()` function. While the public function
`refs_resolve_ref_unsafe()` can be made to behave in the same way by
passing various flags, it does not provide any way to obtain the errno
with which the reference backend failed when reading the reference. As
such, it becomes impossible for us to distinguish generic errors from
the explicit case where the reference wasn't found.

The synopsis treats the `--verify` and the implicit mode the same. They
are slightly different though:
- They accept different sets of flags.
- The implicit mode accepts patterns while the `--verify` mode
accepts references.
Split up the synopsis for these two modes such that we can disambiguate
those differences.
While at it, drop "--quiet" from the pattern mode's synopsis. It does
not make a lot of sense to list patterns, but squelch the listing output
itself. The description for "--quiet" is adapted accordingly.

The git-show-ref(1) command has three different modes, of which one is
implicit and the other two can be chosen explicitly by passing a flag.
But while these modes are standalone and cause us to execute completely
separate code paths, we gladly accept the case where a user asks for
both `--exclude-existing` and `--verify` at the same time even though it
is not obvious what will happen. Spoiler: we ignore `--verify` and
execute the `--exclude-existing` mode.
Let's explicitly detect this invalid usage and die in case both modes
were requested.

Refactor options for the `--exclude-existing` subcommand to be contained

While not immediately obvious, git-show-ref(1) actually implements three
different subcommands:
- `git show-ref <patterns>` can be used to list references that
match a specific pattern.
- `git show-ref --verify <refs>` can be used to list references.
These are _not_ patterns.
- `git show-ref --exclude-existing` can be used as a filter that
reads references from standard input, performing some conversions
on each of them.
Let's make this more explicit in the code by splitting up the three
subcommands into separate functions. This also allows us to address the
confusingly named `patterns` variable, which may hold either patterns or
reference names.

The `pattern` variable is a global variable that tracks either the
reference names (not patterns!) for the `--verify` mode or the patterns
for the non-verify mode. This is a bit confusing due to the slightly
different meanings.
Convert the variable to be local. While this does not yet fix the double
meaning of the variable, this change allows us to address it in a
subsequent patch more easily by explicitly splitting up the different
subcommands of git-show-ref(1).
Note that we introduce a `struct show_ref_data` to pass the patterns to
`show_ref()`. While this is overengineered now, we will extend this
structure in a subsequent patch.

The `--missing` object option in rev-list currently works only with
missing blobs/trees. For missing commits the revision walker fails with
a fatal error.
Let's extend the functionality of `--missing` option to also support
commit objects. This is done by adding a `missing_objects` field to
`rev_info`. This field is an `oidset` to which we'll add the missing
commits as we encounter them. The revision walker will now continue the
traversal and call `show_commit()` even for missing commits. In rev-list
we can then check if the commit is a missing commit and call the
existing code for parsing `--missing` objects.
A scenario where this option would be used is to find the boundary
objects between different object directories. Consider a repository with
a main object directory (GIT_OBJECT_DIRECTORY) and one or more alternate
object directories (GIT_ALTERNATE_OBJECT_DIRECTORIES). In such a
repository, using the `--missing=print` option while disabling the
alternate object directory allows us to find the boundary objects
between the main and alternate object directory.

the object database directly.
As the commit graph is mostly intended as a sort of cache to speed up
parsing of commits we do not want to have diverging behaviour in a
repository with and a repository without commit graphs, no matter
whether they are stale or not. As commits are otherwise immutable, the
only thing that we really need to care about is thus the presence or
absence of a commit.
To address potentially stale commit data that may exist in the graph,
our `lookup_commit_in_graph()` function will check for the commit's
existence in both the commit graph, but also in the object database. So
even if we were able to look up the commit's data in the graph, we would
still pretend as if the commit didn't exist if it is missing in the
object database.
We don't have the same safety net in `parse_commit_in_graph_one()`
though. This function is mostly used internally in "commit-graph.c"
itself to validate the commit graph, and this usage is fine. We do
expose its functionality via `parse_commit_in_graph()` though, which
gets called by `repo_parse_commit_internal()`, and that function is in
turn used in many places in our codebase.
For all I can see this function is never used to directly turn an object
ID into a commit object without additional safety checks before or after
this lookup. What it is being used for though is to walk history via the
parent chain of commits. So when commits in the parent chain of a graph
walk are missing it is possible that we wouldn't notice if that missing
commit was part of the commit graph. Thus, a query like `git rev-parse
HEAD~2` can succeed even if the intermittent commit is missing.
It's unclear whether there are additional ways in which such stale
commit graphs can lead to problems. In any case, it feels like this is a
bigger bug waiting to happen when we gain additional direct or indirect
callers of `repo_parse_commit_internal()`. So let's fix the inconsistent
behaviour by checking for object existence via the object database, as
well.
This check of course comes with a performance penalty. The following
benchmarks have been executed in a clone of linux.git with stable tags
added:
Benchmark 1: git -c core.commitGraph=true rev-list --topo-order --all (git = master)
Time (mean ± σ): 2.913 s ± 0.018 s [User: 2.363 s, System: 0.548 s]
Range (min … max): 2.894 s … 2.950 s 10 runs
Benchmark 2: git -c core.commitGraph=true rev-list --topo-order --all (git = pks-commit-graph-inconsistency)
Time (mean ± σ): 3.834 s ± 0.052 s [User: 3.276 s, System: 0.556 s]
Range (min … max): 3.780 s … 3.961 s 10 runs
Benchmark 3: git -c core.commitGraph=false rev-list --topo-order --all (git = master)
Time (mean ± σ): 13.841 s ± 0.084 s [User: 13.152 s, System: 0.687 s]
Range (min … max): 13.714 s … 13.995 s 10 runs
Benchmark 4: git -c core.commitGraph=false rev-list --topo-order --all (git = pks-commit-graph-inconsistency)
Time (mean ± σ): 13.762 s ± 0.116 s [User: 13.094 s, System: 0.667 s]
Range (min … max): 13.645 s … 14.038 s 10 runs
Summary
git -c core.commitGraph=true rev-list --topo-order --all (git = master) ran
1.32 ± 0.02 times faster than git -c core.commitGraph=true rev-list --topo-order --all (git = pks-commit-graph-inconsistency)
4.72 ± 0.05 times faster than git -c core.commitGraph=false rev-list --topo-order --all (git = pks-commit-graph-inconsistency)
4.75 ± 0.04 times faster than git -c core.commitGraph=false rev-list --topo-order --all (git = master)
We look at a ~30% regression in general, but in general we're still a
whole lot faster than without the commit graph. To counteract this, the
new check can be turned off with the `GIT_COMMIT_GRAPH_PARANOIA` envvar.

Our `lookup_commit_in_graph()` helper tries to look up commits from the
commit graph and, if it doesn't exist there, falls back to parsing it
from the object database instead. This is intended to speed up the
lookup of any such commit that exists in the database. There is an edge
case though where the commit exists in the graph, but not in the object
database. To avoid returning such stale commits the helper function thus
double checks that any such commit parsed from the graph also exists in
the object database. This makes the function safe to use even when
commit graphs aren't updated regularly.
We're about to introduce the same pattern into other parts of our code
base though, namely `repo_parse_commit_internal()`. Here the extra
sanity check is a bit of a tougher sell: `lookup_commit_in_graph()` was
a newly introduced helper, and as such there was no performance hit by
adding this sanity check. If we added `repo_parse_commit_internal()`
with that sanity check right from the beginning as well, this would
probably never have been an issue to begin with. But by retrofitting it
with this sanity check now we do add a performance regression to
preexisting code, and thus there is a desire to avoid this or at least
give an escape hatch.
In practice, there is no inherent reason why either of those functions
should have the sanity check whereas the other one does not: either both
of them are able to detect this issue or none of them should be. This
also means that the default of whether we do the check should likely be
the same for both. To err on the side of caution, we thus rather want to
make `repo_parse_commit_internal()` stricter than to loosen the checks
that we already have in `lookup_commit_in_graph()`.
The escape hatch is added in the form of a new GIT_COMMIT_GRAPH_PARANOIA
environment variable that mirrors GIT_REF_PARANOIA. If enabled, which is
the default, we will double check that commits looked up in the commit
graph via `lookup_commit_in_graph()` also exist in the object database.
This same check will also be added in `repo_parse_commit_internal()`.

As an attempt to come up with a useful mechanism to ensure that
certain messages are left untranslated [*], we earlier wrote
GIT_TEST_GETTEXT_POISON off as a failed experiment.
But the output from the test helper was easier to use while
debugging failed tests, compared to the same test writtein with the
plain-vanilla "grep". Especially when a test that expects a certain
string to appear in the output (e.g. "this test must fail with this
message") fails, "grep message output" would just silently fail and
in a &&-chained sequence of commands, it is hard to tell which step
failed. test_i18ngrep explicitly said "we wanted to see a line that
match this pattern but did not see a hit in this file".
What we have as test_i18ngrep in our tree still retains this verbose
output (even though we got rid of the "poison" support). Let's
rename it to test_grep (because it is no longer about i18n at all)
and then make test_i18ngrep a thin wrapper around it. Existing
callers of test_i18ngrep can be mechanically rewritten to instead
use test_grep over time, but it does not have to be done in this
commit.
[Footnote]
* The idea was that human-facing messages are often translated, but
there are messages that should never be translated. We use
"grep" only for the latter kind of messages, and then run tests
in "poison" mode that spew garbage for translatable messages. If
such a test run fails, it means these messages tested with "grep"
were marked for translation by mistake. test_i18ngrep was to be
used for other messages that are to be translated, and was to
always "succeed" when runing under the "poison" mode.

33d7bdd645 (builtin/reflog.c: use parse-options api for expire, delete
subcommands, 2022-01-06) broke the option --single-worktree of git
reflog expire and added a non-printable short flag for it, presumably by
accident. While before it set the variable "all_worktrees" to 0, now it
sets it to 1, its default value. --no-single-worktree is required now
to set it to 0.
Fix it by replacing the variable with one that has the opposite meaning,
to avoid the negation and its potential for confusion. The new variable
"single_worktree" directly captures whether --single-worktree was given.
Also remove the unprintable short flag SOH (start of heading) because it
is undocumented, hard to use and is likely to have been added by mistake
in connection with the negation bug above.

Let the parse-options code detect and handle the use of options that are
incompatible with --show-current-patch. This requires exposing the
distinction between the "raw" and "diff" sub-modes. Do that by
splitting the mode RESUME_SHOW_PATCH into RESUME_SHOW_PATCH_RAW and
RESUME_SHOW_PATCH_DIFF and stop tracking sub-modes in a separate struct.
The result is a simpler callback function and more precise error
messages. The original reports a spurious argument or a NULL pointer:
$ git am --show-current-patch --show-current-patch=diff
error: options '--show-current-patch=diff' and '--show-current-patch=raw' cannot be used together
$ git am --show-current-patch=diff --show-current-patch
error: options '--show-current-patch=(null)' and '--show-current-patch=diff' cannot be used together
With this patch we get the more precise:
$ git am --show-current-patch --show-current-patch=diff
error: --show-current-patch=diff is incompatible with --show-current-patch
$ git am --show-current-patch=diff --show-current-patch
error: --show-current-patch is incompatible with --show-current-patch=diff

Only a single PARSE_OPT_CMDMODE option can be specified for the same
variable at the same time. This is enforced by get_value(), but the
error messages are imprecise in three ways:
1. If a non-PARSE_OPT_CMDMODE option changes the value variable of a
PARSE_OPT_CMDMODE option then an ominously vague message is shown:
$ t/helper/test-tool parse-options --set23 --mode1
error: option `mode1' : incompatible with something else
Worse: If the order of options is reversed then no error is reported at
all:
$ t/helper/test-tool parse-options --mode1 --set23
boolean: 0
integer: 23
magnitude: 0
timestamp: 0
string: (not set)
abbrev: 7
verbose: -1
quiet: 0
dry run: no
file: (not set)
Fortunately this can currently only happen in the test helper; actual
Git commands don't share the same variable for the value of options with
and without the flag PARSE_OPT_CMDMODE.
2. If there are multiple options with the same value (synonyms), then
the one that is defined first is shown rather than the one actually
given on the command line, which is confusing:
$ git am --resolved --quit
error: option `quit' is incompatible with --continue
3. Arguments of PARSE_OPT_CMDMODE options are not handled by the
parse-option machinery. This is left to the callback function. We
currently only have a single affected option, --show-current-patch of
git am. Errors for it can show an argument that was not actually given
on the command line:
$ git am --show-current-patch --show-current-patch=diff
error: options '--show-current-patch=diff' and '--show-current-patch=raw' cannot be used together
The options --show-current-patch and --show-current-patch=raw are
synonyms, but the error accuses the user of input they did not actually
made. Or it can awkwardly print a NULL pointer:
$ git am --show-current-patch=diff --show-current-patch
error: options '--show-current-patch=(null)' and '--show-current-patch=diff' cannot be used together
The reasons for these shortcomings is that the current code checks
incompatibility only when encountering a PARSE_OPT_CMDMODE option at the
command line, and that it searches the previous incompatible option by
value.
Fix the first two points by checking all PARSE_OPT_CMDMODE variables
after parsing each option and by storing all relevant details if their
value changed. Do that whether or not the changing options has the flag
PARSE_OPT_CMDMODE set. Report an incompatibility only if two options
change the variable to different values and at least one of them is a
PARSE_OPT_CMDMODE option. This changes the output of the first three
examples above to:
$ t/helper/test-tool parse-options --set23 --mode1
error: --mode1 is incompatible with --set23
$ t/helper/test-tool parse-options --mode1 --set23
error: --set23 is incompatible with --mode1
$ git am --resolved --quit
error: --quit is incompatible with --resolved
Store the argument of PARSE_OPT_CMDMODE options of type OPTION_CALLBACK
as well to allow taking over the responsibility for compatibility
checking from the callback function. The next patch will use this
capability to fix the messages for git am --show-current-patch.
Use a linked list for storing the PARSE_OPT_CMDMODE variables. This
somewhat outdated data structure is simple and suffices, as the number
of elements per command is currently only zero or one. We do support
multiple different command modes variables per command, but I don't
expect that we'd ever use a significant number of them. Once we do we
can switch to a hashmap.
Since we no longer need to search the conflicting option, the all_opts
parameter of get_value() is no longer used. Remove it.
Extend the tests to check for both conflicting option names, but don't
insist on a particular order.

The description of the `git bisect run` command syntax at the beginning
of the manpage is `git bisect run <cmd>...`, which isn't quite clear
about what `<cmd>` is or what the `...` mean; one could think that it is
the whole (quoted) command line with all arguments in a single string,
or that it supports multiple commands, or that it doesn't accept
commands with arguments at all.
Change to `git bisect run <cmd> [<arg>...]` to clarify the syntax,
in both the manpage and the `git bisect -h` command output.
Additionally, change `--term-{new,bad}` et al to `--term-(new|bad)`
for consistency with the synopsis syntax conventions.

support for `--preserve-merges`") and commit 10cdb9f38a ("rebase: rename
the two primary rebase backends"). The latter commit also renamed
imply_interactive() to imply_merge().

If the user writes a message via --compose, send-email will pick up
various headers like "From", "Subject", etc and use them for other
patches as if they were specified on the command-line. But we don't
handle "To", "Cc", or "Bcc" this way; we just tell the user "those
aren't interpeted yet" and ignore them.
But it seems like an obvious thing to want, especially as the same
feature exists when the cover letter is generated separately by
format-patch. There it is gated behind the --to-cover option, but I
don't think we'd need the same control here; since we generate the
--compose template ourselves based on the existing input, if the user
leaves the lines unchanged then the behavior remains the same.
So let's fill in the implementation; like those other headers we already
handle, we just need to assign to the initial_* variables. The only
difference in this case is that they are arrays, so we'll feed them
through parse_address_line() to split them (just like we would when
reading a single string via prompting).

This reverts commit b6049542b97e7b135e0e82bf996084d461224d32.
Prior to that commit, we read the results of the user editing the
"--compose" message in a loop, picking out parts we cared about, and
streaming the result out to a ".final" file. That commit split the
reading/interpreting into two phases; we'd now read into a hash, and
then pick things out of the hash.
The goal was making the code more readable. And in some ways it did,
because the ugly regexes are confined to the reading phase. But it also
introduced several bugs, because now the two phases need to match each
other. In particular:
- we pick out headers like "Subject: foo" with a case-insensitive
regex, and then use the user-provided header name as the key in a
case-sensitive hash. So if the user wrote "subject: foo", we'd no
longer recognize it as a subject.
- the namespace for the hash keys conflates header names with meta
information like "body". If you put "body: foo" in your message, it
would be misinterpreted as the actual message body (nobody is likely
to do that in practice, but it seems like an unnecessary danger).
- the handling for to/cc/bcc is totally broken. The behavior before
that commit is to recognize and skip those headers, with a note to
the user that they are not yet handled. Not great, but OK. But
after the patch, the reading side now splits the addresses into a
perl array-ref. But the interpreting side doesn't handle this at
all, and blindly prints the stringified array-ref value. This leads
to garbage like:
(mbox) Adding to: ARRAY (0x555b4345c428) from line 'To: ARRAY(0x555b4345c428)'
error: unable to extract a valid address from: ARRAY (0x555b4345c428)
What to do with this address? ([q]uit|[d]rop|[e]dit):
Probably not a huge deal, since nobody should even try to use those
headers in the first place (since they were not implemented). But
the new behavior is worse, and indicative of the sorts of problems
that come from having the two layers.
The revert had a few conflicts, due to later work in this area from
15dc3b9161 (send-email: rename variable for clarity, 2018-03-04) and
d11c943c78 (send-email: support separate Reply-To address, 2018-03-04).
I've ported the changes from those commits over as part of the conflict
resolution.
The new tests show the bugs. Note the use of GIT_SEND_EMAIL_NOTTY in the
second one. Without it, the test is happy to reach outside the test
harness to the developer's actual terminal (when run with the buggy
state before this patch).

The documentation for git-send-email lists the headers handled specially
by --compose in a way that implies that this is the complete set of
headers that are special. But one more was added by d11c943c78
(send-email: support separate Reply-To address, 2018-03-04) and never
documented.
Let's add it, and reword the documentation slightly to avoid having to
specify the list of headers twice (as it is growing and will continue to
do so as we add new features).
If you read the code, you may notice that we also handle MIME-Version
specially, in that we'll avoid over-writing user-provided MIME headers.
I don't think this is worth mentioning, as it's what you'd expect to
happen (as opposed to the other headers, which are picked up to be used
in later emails). And certainly this feature existed when the
documentation was expanded in 01d3861217 (git-send-email.txt: describe
--compose better, 2009-03-16), and we chose not to mention it then.

Die gracefully when `git grep --no-index` is run outside of a Git
repository and the path is outside the directory tree.
If you are not in a Git repository and say:
git grep --no-index search ..
You trigger a `BUG`:
BUG: environment.c:213: git environment hasn't been setup
Aborted (core dumped)
Because `..` is a valid path which is treated as a pathspec. Then
`pathspec` figures out that it is not in the current directory tree. The
`BUG` is triggered when `pathspec` tries to advise the user about how the
path is not in the current (non-existing) repository.

git-p4.py would attempt to put a symlink in LFS if its file extension
matched git-p4.largeFileExtensions.
Git LFS doesn't store symlinks because smudge/clean filters don't handle
symlinks. They never get passed to the filter process nor the
smudge/clean filters, nor could that occur without a change to the
protocol or command-line interface. Unless Git learned how to send them
to the filters, Git LFS would have a hard time using them in any useful
way.
Git LFS's goal is to move large files out of the repository history, and
symlinks are functionally limited to 4 KiB or a similar size on most
systems.

Some tests in t7601 use "test -f" and "test ! -f" to see if a path
exists or is missing.
Use test_path_is_file and test_path_is_missing helper functions to
clarify these tests a bit better. This especially matters for the
"missing" case because "test ! -f F" will be happy if "F" exists as a
directory, but the intent of the test is that "F" should not exist, even
as a directory. The updated code expresses this better.

`git am` passes the value given to its `--whitespace` option through
to the underlying `git apply`, and the value is called <action> over
there. Fix the documentation for the command that calls the value
<option> to say <action> instead.
Note that the option help given by `git am -h` already calls the
value <action>, so there is no need to make a matching change there.
