The set of aliases used for the pine --dump-aliases test do not
perfectly mesh with the way the pine address book is defined. While
technically all valid, there are some oddities including bob's name
being partially split so that the actual address is returned as
"Bobbyton <bob@example.com>". A strict reading of the pine documentation
indicates that the address should either be of the form
"address@domain" or a comma separated list of address, name/address
pairs, or other aliases enclosed by ().
The parsing implementation in git-send-email is not as strict, but it
makes sense to ensure the test data used is. Although the --dump-aliases
test does not make use of the address data, it is helpful to avoid
giving future developers the wrong impression of the file format.
Also add an alias which translates to multiple addresses using the ()
format.

The .mailrc alias file format documents that multiple addresses are
separated by spaces. The alias file used in the t9001 --dump-aliases
mailrc test have addresses which include both a name and email. These
are unquoted, so git send-email will parse this as an alias that
translates to multiple independent addresses.
The existing test does not care about this, as --dump-aliases only dumps
the alias and not the address. However, it is incorrect for a future
where --dump-aliases could also dump the mail addresses.
Fix the test to quote the aliases properly, so that they translate to a
single address.

All the Perforce tests are free of memory leaks. This went unnoticed
because most folks do not have p4 and p4d installed on their computers.
Consequently, given that the prerequisites for running those tests
aren't fulfilled, `TEST_PASSES_SANITIZE_LEAK=check` won't notice that
those tests are indeed memory leak free.
Mark those tests accordingly.

Update our Perforce version from r21.2 to r23.2. Note that the updated
version is not the newest version. Instead, it is the last version where
the way that Perforce is being distributed remains the same as in r21.2.
Newer releases stopped distributing p4 and p4d executables as well as
the macOS archives directly and would thus require more work.

Some of the tests in t98xx modify the Perforce depot in ways that the
tool wouldn't normally allow. This is done to test behaviour of git-p4
in certain edge cases that we have observed in the wild, but which
should in theory not be possible.
Naturally, modifying the depot on disk directly is quite intimate with
the tool and thus prone to breakage when Perforce updates the way that
data is stored. And indeed, those tests are broken nowadays with r23 of
Perforce. While a file revision was previously stored as a plain file
"depot/file,v", it is now stored in a directory "depot/file,d" with
compression.
Adapt those tests to handle both old- and new-style depot layouts.

When Git adds a file requiring encoding conversion and tracing of encoding
conversion is not requested via the GIT_TRACE_WORKING_TREE_ENCODING
environment variable, the `trace_encoding()` function still allocates &
prepares "human readable" copies of the file contents before and after
conversion to show in the trace. This results in a high memory footprint
and increased runtime without providing any user-visible benefit.
This fix introduces an early exit from the `trace_encoding()` function
when tracing is not requested, preventing unnecessary memory allocation
and processing.

Our coding guide is inconsistent with how it uses spaces inside of
initializers (`struct foo bar = { something }`). While we mostly carry
the space between open and closing braces and the initialized members,
in one case we don't.
Fix this one instance such that we consistently carry the space. This is
also consistent with how clang-format formats such initializers.

We semi-regularly have discussions around whether a function shall be
named `S_release()`, `S_clear()` or `S_free()`. Indeed, it may not be
obvious which of these is preferable as we never really defined what
each of these variants means exactly.
Carve out a space where we can add idiomatic names for common functions
in our coding guidelines and define each of those functions. Like this,
we can get to a shared understanding of their respective semantics and
can easily point towards our style guide in future discussions such that
our codebase becomes more consistent over time.
Note that the intent is not to rename all functions which violate these
semantics right away. Rather, the intent is to slowly converge towards a
common style over time.

We nowadays have a proper mishmash of struct-related functions that are
called `<verb>_<struct>` (e.g. `clear_prio_queue()`) versus functions
that are called `<struct>_<verb>` (e.g. `strbuf_clear()`). While the
former style may be easier to tie into a spoken conversation, most of
our communication happens in text anyway. Furthermore, prefixing
functions with the name of the structure they operate on makes it way
easier to group them together, see which functions are related, and will
also help folks who are using code completion.
Let's thus settle on one style, namely the one where functions start
with the name of the structure they operate on.

In [1], we have improved our clang-format configuration to also specify
the style for how to indent preprocessor directives. But while we have
settled the question of where to put the indentation, either before or
after the hash sign, we didn't specify exactly how to indent.
With the current configuration, clang-format uses tabs to indent each
level of nested preprocessor directives, which is in fact unintentional
and never done in our codebase. Instead, we use a mixture of indenting
by either one or two spaces, where using a single space is somewhat more
common.
Adapt our clang-format configuration accordingly by specifying an
indentation width of one space.

With "git notes add -C $blob", the given blob contents are to be made
into a note without involving an editor. But when "--allow-empty" is
given, the editor is invoked, which can cause problems for
non-interactive callers[1].
This behaviour started with 90bc19b3ae (notes.c: introduce
'--separator=<paragraph-break>' option, 2023-05-27), which changed
editor invocation logic to check for a zero length note_data buffer.
Restore the original behaviour of "git note" that takes the contents
given via the "-m", "-C", "-F" options without invoking an editor, by
checking for any prior parameter callbacks, indicated by a non-zero
note_data.msg_nr. Remove the now-unneeded note_data.given flag.
Add a test for this regression by checking whether GIT_EDITOR is
invoked alongside "git notes add -C $empty_blob --allow-empty"

The behavior of a one-shot environment variable assignment of the form
"VAR=val cmd" is unspecified according to POSIX when "cmd" is a shell
function. Indeed the behavior differs between shell implementations and
even different versions of the same shell, thus should be avoided.
As such, check-non-portable-shell.pl warns when it detects such usage.
However, a limitation of the check is that it only detects such
invocations when variable assignment (i.e. `VAR=val`) is the first thing
on the line. Thus, it can easily be fooled by an invocation such as:
echo X | VAR=val shell-func
Address this shortcoming by loosening the check so that the variable
assignment can be recognized even when not at the beginning of the line.

Most problems reported by check-non-portable-shell are accompanied by
advice suggesting how the test author can repair the problem. For
instance:
error: egrep/fgrep obsolescent (use grep -E/-F)
However, when one-shot variable assignment is detected when calling a
shell function (i.e. `VAR=val shell-func`), the problem is reported, but
no advice is given. The lack of advice is particularly egregious since
neither the problem nor the workaround are likely well-known by
newcomers to the project writing tests for the first time. Address this
shortcoming by recommending the use of `test_env` which is tailor made
for this specific use-case.

When a0a630192d (t/check-non-portable-shell: detect "FOO=bar
shell_func", 2018-07-13) added the check for one-shot environment
variable assignment for shell functions, the primary reason given for
avoiding them was that, under some shells, the assignment outlives the
invocation of the shell function, thus could potentially negatively
impact subsequent commands in the same test, as well as subsequent
tests.
However, it has recently become apparent that this is not the only
potential problem with one-shot assignments and shell functions. Another
problem is that some shells do not actually export the variable to
commands which the function invokes[1]. More significantly, however, the
behavior of one-shot assignments with shell functions is not specified
by POSIX[2].
Given this new understanding, the presented error message ("assignment
extends beyond 'shell_func'") is too specific and potentially
misleading. Address this by emitting a less specific error message.
(Note that the wording "is not portable" is chosen over the more
specific "behavior not specified by POSIX" for consistency with almost
all other error message issued by this "lint" script.)

The behavior of a one-shot environment variable assignment of the form
"VAR=val cmd" is unspecified according to POSIX when "cmd" is a shell
function. Indeed the behavior differs between shell implementations and
even different versions of the same shell. One such problematic behavior
is that, with some shells, the assignment will outlive the invocation of
the function, thus may potentially impact subsequent commands in the
test, as well as subsequent tests. A common way to work around the
problem is to wrap a subshell around the one-shot assignment, thus
ensuring that the assignment is short-lived.
In this test, the subshell is employed precisely for this purpose; other
side-effects of the subshell, such as losing the effect of `test_tick`
which is invoked by `test_commit`, are immaterial.
These days, we can take advantage of `test_commit --author` to more
clearly convey that the test is interested only in overriding the author
of the commit.

The documentation to "git rebase" says that the line numbers (in the
rebased change) may not exactly be the same as the line numbers the
change gets replayed on top of the new base, but uses a wrong noun
"fuzz". It should have said "offset".
They are both terms of art. "fuzz" is about context lines not
exactly matching. "offset" is about the difference in the location
that a change was taken from the original and the change gets
replayed on the target. "offset" is often inevitable and part of
normal life. "fuzz" on the other hand is often a sign of trouble
(and indeed "Git" refuses to apply a change with "fuzz", except
there are options to be fuzzy about whitespaces).

Make the print command trigger the pager when invoked using a capital
'P', to make it easier for the user to review long hunks.
Note that if the PAGER ends unexpectedly before we've been able to send
the payload, perhaps because the user is not interested in the whole
thing, we might receive a SIGPIPE, which would abruptly and unexpectedly
terminate the interactive session for the user.
Therefore, we need to ignore a possible SIGPIPE signal. Add a test for
this, in addition to the test for normal operation.
For the SIGPIPE test, we need to make sure that we completely fill the
operating system's buffer, otherwise we might not trigger the SIGPIPE
signal. The normal size of this buffer in different OSs varies from a
few KBs to 1MB. Use a payload large enough to guarantee that we exceed
this limit.

Since f67b45f862 (Introduce trivial new pager.c helper infrastructure,
2006-02-28) we have the machinery to send our output to a pager.
That machinery, once set up, does not allow us to regain the original
stdio streams.
In the interactive commands (i.e.: add -p) we want to use the pager for
some output, while maintaining the interaction with the user.
Modify the pager machinery so that we can use `setup_pager()` and, once
we've finished sending the desired output for the pager, wait for the
pager termination using a new function `wait_for_pager()`. Make this
function reset the pager machinery before returning.
One specific point to note is that we avoid forking the pager in
`setup_pager()` if the configured pager is an empty string [*1*] or
simply "cat" [*2*]. In these cases, `setup_pager()` does nothing and
therefore `wait_for_pager()` should not be called.
We could modify `setup_pager()` to return an indication of these
situations, so we could avoid calling `wait_for_pager()`.
However, let's avoid transferring that responsibility to the caller and
instead treat the call to `wait_for_pager()` as a no-op when we know we
haven't forked the pager.

We send errors to the pager since 61b80509e3 (sending errors to stdout
under $PAGER, 2008-02-16).
In a8335024c2 (pager: do not dup2 stderr if it is already redirected,
2008-12-15) an exception was introduced to avoid redirecting stderr if
it is not connected to a terminal.
In such exceptional cases, the close(STDERR_FILENO) we're doing in
close_pager_fds, is unnecessary.
Furthermore, in a subsequent commit we're going to introduce changes
that will involve using close_pager_fds multiple times.

sensible.

The previous step introduced docinfo.html to be used to tweak the
CSS used by the asciidoctor, that by default renders <code> inside
<pre> as a block element, breaking the SYNOPSIS section of a few
pages that adopted a new convention we use since Git 2.45.
But in this project, HTML files are all generated. We do not force
any human to write HTML by hand, which is an unusual and cruel
punishment. "*.html" is in the .gitignore file, and "make clean"
removes them. Having a tracked .html file makes "make clean" make
the tree dirty by removing the tracked docinfo.html file.
Let's do an obvious, minimum and stupid workaround to generate that
file at runtime instead. The mark-up is being rethought in a major
way for the next development cycle, and the CSS workaround we added
in the previous step may have to adjusted, possibly in a large way,
anyway.

For 'clang-format', setting 'RemoveBracesLLVM' to 'true', adds a check
to ensure we avoid curly braces for single-statement bodies in
conditional blocks.
However, the option does come with two warnings [1]:
This option will be renamed and expanded to support other styles.
and
Setting this option to true could lead to incorrect code formatting
due to clang-format’s lack of complete semantic information. As
such, extra care should be taken to review code changes made by
this option.
The latter seems to be of concern. While we want to experiment with the
rule, adding it to the in-tree '.clang-format' could affect end-users.
Let's only add it to the CI jobs for now. With time, we can evaluate
its efficacy and decide if we want to add it to '.clang-format' or
retract it entirely. We do so, by adding the existing rules in
'.clang-format' and this rule to a temp file outside the working tree,
which is then used by 'git clang-format'. This ensures we don't murk
with files in-tree.

The 'check-whitespace' CI script exits gracefully if no base commit is
provided or if an invalid revision is provided. This is not good because
if a particular CI provides an incorrect base_commit, it would fail
successfully.
This is exactly the case with the GitLab CI. The CI is using the
"$CI_MERGE_REQUEST_TARGET_BRANCH_SHA" variable to get the base commit
SHA, but variable is only defined for _merged_ pipelines. So it is empty
for regular pipelines [1]. This should've failed the check-whitespace
job.
Let's fallback to 'CI_MERGE_REQUEST_DIFF_BASE_SHA' if
"CI_MERGE_REQUEST_TARGET_BRANCH_SHA" isn't available in GitLab CI,
similar to the previous commit. Let's also add a check for incorrect
base_commit in the 'check-whitespace.sh' script. While here, fix a small

We don't run style checks on our CI, even though we have a
'.clang-format' setup in the repository. Let's add one, the job will
validate only against the new commits added and will only run on merge
requests. Since we're introducing it for the first time, let's allow
this job to fail, so we can validate if this is useful and eventually
enforce it.
For GitHub, we allow the job to pass by adding 'continue-on-error: true'
to the workflow. This means the job would show as passed, even if the
style check failed. To know the status of the job, users have to
manually check the logs.
For GitLab, we allow the job to pass by adding 'allow_failure: true', to
the job. Unlike GitHub, here the job will show as failed with a yellow
warning symbol, but the pipeline would still show as passed.
Also for GitLab, we use the 'CI_MERGE_REQUEST_TARGET_BRANCH_SHA'
variable by default to obtain the base SHA of the merged pipeline (which
is only available for merged pipelines [1]). Otherwise we use the
'CI_MERGE_REQUEST_DIFF_BASE_SHA' variable.

sense to formalize them:

The spacing around colons is currently not standardized and as such we
have the following practices in our code base:
- Spacing around the colon `int bf : 1`: 146 instances
- No spacing around the colon `int bf:1`: 148 instances
- Spacing before the colon `int bf :1`: 6 instances
- Spacing after the colon `int bf: 1`: 12 instances
Let's formalize this by picking the most followed pattern and add the
corresponding style to '.clang-format'.

We do not have a rule around the indentation of preprocessor directives.
This was also discussed on the list [1], noting how there is often
inconsistency in the styling. While there was discussion, there was no
conclusion around what is the preferred style here. One style being
indenting after the hash:
#if FOO
# if BAR
# include <foo>
# endif
#endif
The other being before the hash:
#if FOO
#if BAR
#include <foo>
#endif
#endif
Let's pick the former and add 'IndentPPDirectives: AfterHash' value to
our '.clang-format'. There is no clear reason to pick one over the
other, but it would definitely be nicer to be consistent.

It was reported that t1460-refs-migrate.sh fails when using Cygwin with
errors like the following:
error: could not link file '.git/ref_migration.sr9pEF/reftable' to '.git/reftable': Permission denied
As some debugging surfaced, the root cause of this is that some files of
the newly-initialized ref store are still open when the target format is
the "reftable" format, and Cygwin refuses to rename open files.
Fix this issue by closing the new ref store before renaming its files
into place. This is a slight change in behaviour compared to before,
where we kept the new ref store open and then updated the repository's
ref store to point to it.
While we could re-open the new ref store after we have moved files
around, this is ultimately unnecessary. We know that the only user of
`repo_migrate_ref_storage_format()` is the git-refs(1) command, and it
won't access the ref store after it has been migrated anyway. So
reinitializing the ref store would be a waste of time. Regardless of
that it is still sensible to leave the repository in a consistent state.
But instead of reinitializing the ref store, we can simply unset the
repo's ref store altogether and let `get_main_ref_store()` lazily
initialize the new ref store as required.

Over the years, we accumulated the community wisdom to avoid the
common "one-short export" construct for shell functions, but seem to
have lost on which exact platform it is known to fail. Now during
an investigation on a breakage for a recent topic, we found one
example of failing shell. Let's document that.
This does *not* mean that we can freely start using the construct
once Ubuntu 20.04 is retired. But it does mean that we cannot use
the construct until Ubuntu 20.04 is fully retired from the machines
that matter. Moreover, posix explicitly says that the behaviour for
the construct is unspecified.

The second line of the synopsis, starting with [--dry-run] has a
dangling closing paren in the second optional group. Probably added by
mistake, so remove it.

Since 76880f0510c (doc: git-clone: apply new documentation formatting
guidelines, 2024-03-29), the synopsis of `git clone`'s manual page is
rendered differently than before; Its parent commit did the same for
`git init`.
The result looks quite nice. When rendered with AsciiDoc, that is. When
rendered using AsciiDoctor and displayed in a graphical web browser such
as Firefox, Chrome, Edge, etc, the result is quite unpleasant to my eye,
reading something like this:
SYNOPSIS
git clone
[
--template=
<template-directory>]
[
-l
] [
-s
] [
--no-hardlinks
] [
-q
] [
[... continuing like this ...]
The reason is that AsciiDoctor's default style sheet contains this (see
https://github.com/asciidoctor/asciidoctor/blob/854923b15533/src/stylesheets/asciidoctor.css#L519-L521
for context):
pre > code {
display: block;
}
It is this `display: block` that forces the parts that are enclosed in
`<code>` tags (such as the `git clone` or the `--template=` part) to be
rendered on their own line.
Side note: This seems not to affect console web browsers like `lynx` or
`w3m`, most likely because most style sheet directions cannot be
respected in text terminals and therefore they seem to punt on style
sheets altogether.
To fix this, let's apply the method recommended by AsciiDoctor in
https://docs.asciidoctor.org/asciidoctor/latest/html-backend/default-stylesheet/#customize-docinfo
to partially override AsciiDoctor's default style sheet so that the
`<code>` sections of the synopsis are no longer each rendered on their
own, individual lines.
This fixes https://github.com/git-for-windows/git/issues/5063.
Even on the Git home page, where AsciiDoctor's default stylesheet is
_not_ used, this change resulted in some unpleasant rendering where not
only the font is changed for the `<code>` sections of the synopsis, but
padding and a different background color make the visual impression
quite uneven. This has been addressed in the meantime, via
https://github.com/git/git-scm.com/commit/a492d0565512.

After the user has edited a hunk the number of lines in the pre- and
post- image lines is recounted the hunk header can be updated before
passing the hunk to "git apply". The recounting code correctly handles
empty context lines where the leading ' ' is omitted by treating '\n'
and '\r' as context lines.
Update this code to use normalize_marker() so that the handling of empty
context lines is consistent with the rest of the hunk parsing
code. There is a small change in behavior as normalize_marker() only
treats "\r\n" as an empty context line rather than any line starting
with '\r'. This should not matter in practice as Macs have used Unix
line endings since MacOs 10 was released in 2001 and if it transpires
that someone is still using an earlier version of MacOs where lines end
with '\r' then we will need to change the handling of '\r' in
normalize_marker() anyway.
