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.

When we process a user's name (as in user.name), we strip all
leading and trailing crud from it. Right now, we consider a dot
a crud character, and strip it off.
However, this is unsuitable for many personal names because humans
frequently have abbreviated suffixes, such as "Jr." or "Sr." at the end
of their names, and this corrupts them. Some other users may wish to
use an abbreviated name or initial, which will pose a problem especially
in cultures that write the family name first, followed by the personal
name.
Since the current approach causes lots of practical problems, let's
avoid it by no longer considering a dot to be crud.
Note that "." in the name forces the entire name to be quoted to
please mailers, but stripping "." only at the beginning and the end
does not help a name with "." in the middle (like "brian m. carlson")
so this change will not make it much worse. A name like "Given
Family, Jr." that did not have to be quoted now would need to be, in
order to be placed on the e-mail headers, though.
This is based on a weather-balloon patch by Jeff King sent in Aug 2021

Even though the cat-file command with `--batch-check` option does not
complain when `--use-mailmap` option is given, the latter option is
ignored. Compute the size of the object after replacing the idents and
report it instead.
In order to make `--batch-check` option honour the mailmap mechanism we
have to read the contents of the commit/tag object.
There were two ways to do it:
1. Make two calls to `oid_object_info_extended()`. If `--use-mailmap`
option is given, the first call will get us the type of the object
and second call will only be made if the object type is either a
commit or tag to get the contents of the object.
2. Make one call to `oid_object_info_extended()` to get the type of the
object. Then, if the object type is either of commit or tag, make a
call to `repo_read_object_file()` to read the contents of the object.
I benchmarked the following command with both the above approaches and
compared against the current implementation where `--use-mailmap`
option is ignored:
`git cat-file --use-mailmap --batch-all-objects --batch-check --buffer
--unordered`
The results can be summarized as follows:
Time (mean ± σ)
default 827.7 ms ± 104.8 ms
first approach 6.197 s ± 0.093 s
second approach 1.975 s ± 0.217 s
Since, the second approach is faster than the first one, I implemented
it in this patch.
The command git cat-file can now use the mailmap mechanism to replace
idents with canonical versions for commit and tag objects. There are
several options like `--batch`, `--batch-check` and `--batch-command`
that can be combined with `--use-mailmap`. But the documentation for
`--batch`, `--batch-check` and `--batch-command` doesn't say so. This
patch fixes that documentation.

Even though the cat-file command with `-s` option does not complain when
`--use-mailmap` option is given, the latter option is ignored. Compute
the size of the object after replacing the idents and report it instead.
In order to make `-s` option honour the mailmap mechanism we have to

`oid_object_info_extended()` to get the contents of the object and store
in `buf`. `buf` is later freed in the function.

git-cat-file is used by tools like GitLab to get commit tag contents
that are then displayed to users. This content which has author,
committer or tagger information, could benefit from passing through the
mailmap mechanism before being sent or displayed.
This patch adds --[no-]use-mailmap command line option to the git
cat-file command. It also adds --[no-]mailmap option as an alias to
--[no-]use-mailmap.
This patch also introduces new test cases to test the mailmap mechanism in
git cat-file command.

It does not make sense to make ".gitattributes", ".gitignore" and
".mailmap" symlinks, as they are supposed to be usable from the
object store (think: bare repositories where HEAD:.mailmap etc. are
used). When these files are symbolic links, we used to read the
contents of the files pointed by them by mistake, which has been
corrected.
* jk/open-dotgitx-with-nofollow:
mailmap: do not respect symlinks for in-tree .mailmap
exclude: do not respect symlinks for in-tree .gitignore
attr: do not respect symlinks for in-tree .gitattributes
exclude: add flags parameter to add_patterns()
attr: convert "macro_ok" into a flags field
add open_nofollow() helper
|

As with .gitattributes and .gitignore, we would like to make sure that
.mailmap files are handled consistently whether read from the a blob (as
is the default behavior in a bare repo) or from the filesystem.
Likewise, we would like to avoid reading out-of-tree files pointed to by
a symlink, which could have security implications in certain setups.
We can cover both by using open_nofollow() when opening the in-tree
files. We'll continue to follow links for mailmap.file, as well as when
reading .mailmap from the current directory when outside of a repository
entirely.

When trying to find a .mailmap file, we will always look for it in the
current directory. This makes sense in a repository with a working tree,
since we'd always go to the toplevel directory at startup. But for a
bare repository, it can be confusing. With an option like --git-dir (or
$GIT_DIR in the environment), we don't chdir at all, and we'd read
.mailmap from whatever directory you happened to be in before starting
Git.
(Note that --git-dir without specifying a working tree historically
means "the current directory is the root of the working tree", but most
bare repositories will have core.bare set these days, meaning they will
realize there is no working tree at all).
The documentation for gitmailmap(5) says:
If the file `.mailmap` exists at the toplevel of the repository[...]
which likewise reinforces the notion that we are looking in the working
tree.
This patch prevents us from looking for such a file when we're in a bare
repository. This does break something that used to work:
cd bare.git
git cat-file blob HEAD:.mailmap >.mailmap
git shortlog
But that was never advertised in the documentation. And these days we
have mailmap.blob (which defaults to HEAD:.mailmap) to do the same thing
in a much cleaner way.
However, there's one more interesting case: we might not have a
repository at all! The git-shortlog command can be run with git-log
output fed on its stdin, and it will apply the mailmap. In that case, it
probably does make sense to read .mailmap from the current directory.
This patch will continue to do so.
That leads to one even weirder case: if you run git-shortlog to process
stdin, the input _could_ be from a different repository entirely. Should
we respect the in-tree .mailmap then? Probably yes. Whatever the source
of the input, if shortlog is running in a repository, the documentation
claims that we'd read the .mailmap from its top-level (and of course
it's reasonably likely that it _is_ from the same repo, and the user
just preferred to run git-log and git-shortlog separately for whatever
reason).
The included test covers these cases, and we now document the "no repo"
case explicitly.
We also add a test that confirms we find a top-level ".mailmap" even
when we start in a subdirectory of the working tree. This worked both
before and after this commit, but we never tested it explicitly (it
works because we always chdir to the top-level of the working tree if
there is one).

In the "git blame --porcelain" output, lines that ends with three
integers may not be the line that shows a commit object with line
numbers and block length (the contents from the blamed file or the
summary field can have a line that happens to match). Also, the
names of the author may have more than three SP separated tokens
("git blame -L242,+1 cf6de18aabf7 Documentation/SubmittingPatches"
gives an example). The existing "grep -E | cut" pipeline is a bit
too loose on these two points.
While they can be assumed on the test data, it is not so hard to
use the right pattern from the documented format, so let's do so.

Change the mailmap documentation added in 0925ce4d49 (Add map_user()
and clear_mailmap() to mailmap, 2009-02-08) to continue discussing the
Jane/Joe example. I think this makes things a lot less confusing as
we're building up more complex examples using one set of data which
covers all the things we'd like to discuss.
Also add tests to assert that what our documentation says is what's
actually happening. This is mostly (or entirely) covered by existing
tests which I'm not deleting, but having these tests for the synopsis
makes it easier to follow-along while reading the tests & docs.

That we silently ignore missing mailmap.file or mailmap.blob values is
intentional. See 938a60d64f (mailmap: clean up read_mailmap error

Change a test that used a custom fuzzing function since
bfdfa3d414 (t4203 (mailmap): stop hardcoding commit ids and dates,
2010-10-15) to just use the "blame --porcelain" output instead.
We could use the same pattern as 0ba9c9a0fb (t8008: rely on
rev-parse'd HEAD instead of sha1 value, 2017-07-26) does to do this,
but there wouldn't be any point. We're not trying to test "blame"
output here in general, just that "blame" pays attention to the
mailmap.
So it's sufficient to get the blamed line(s) and authors from the
output, which is much easier with the "--porcelain" option.
It would still be possible for there to be a bug in "blame" such that
it uses the mailmap for its "--porcelain" output, but not the regular
output. Let's test for that simply by checking if specifying the
mailmap changes the output.

The --stdin tests setup the "contact" file in the main setup, let's
instead set it up in the test that uses it.
Also refactor the first test so it's obvious that the point of it is
that "check-mailmap" will spew its input as-is when given no
argument. For that one we can just use the "expect" file as-is.
Also add tests for how other "--stdin" cases are handled, e.g. one
where we actually do a mapping.
For the rest of --stdin testing we just assume we're going to get the
same output. We could follow-up and make sure everything's
round-tripped through both --stdin and the file/blob backends, but I
don't think there's much point in that.

Refactor the mailmap tests to:
* Setup "actual" test files in the body of "test_expect_success"
* Don't have X of "test_expect_success X Y" be an unquoted string.
* Not to carry over test config between tests, and instead use
"test_config".
* Replace various "echo" a line-at-a-time patterns with here-docs.
* Change a case of "log.mailmap=False" to use the lower-case
"false". Both work, but this ends up in git-config's boolean
parsing and these atypical values are tested for elsewhere. Let's
use the lower-case to not draw the reader's attention to this
abnormality.
* Remove commentary asserting that things work a given way in favor
of simply testing for it, i.e. in the case of a .mailmap file
outside of the repository.

In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:
$ git checkout HEAD -- \
t/t0027-auto-crlf.sh t/t0060-path-utils.sh \
t/t1011-read-tree-sparse-checkout.sh \
t/t1305-config-include.sh t/t1309-early-config.sh \

t/t9302-fast-import-unpack-limit.sh
We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:
$ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' t/t980[0167]*.sh t/t9811*.sh

Displaying only the author's username saves a lot of columns on the screen.
Existing 'e/E' (as in "%ae" and "%aE") placeholders would show the

Using 'test_must_be_empty' is shorter and more idiomatic than
>empty &&
test_cmp empty out
as it saves the creation of an empty file. Furthermore, sometimes the
expected empty file doesn't have such a descriptive name like 'empty',
and its creation is far away from the place where it's finally used
for comparison (e.g. in 't7600-merge.sh', where two expected empty
files are created in the 'setup' test, but are used only about 500
lines later).
These cases were found by instrumenting 'test_cmp' to error out the
test script when it's used to compare empty files, and then converted
manually.
Note that even after this patch there still remain a lot of cases
where we use 'test_cmp' to check empty files:
- Sometimes the expected output is not hard-coded in the test, but
'test_cmp' is used to ensure that two similar git commands produce
the same output, and that output happens to be empty, e.g. the
test 'submodule update --merge - ignores --merge for new
submodules' in 't7406-submodule-update.sh'.
- Repetitive common tasks, including preparing the expected results
and running 'test_cmp', are often extracted into a helper
function, and some of this helper's callsites expect no output.
- For the same reason as above, the whole 'test_expect_success'
block is within a helper function, e.g. in 't3070-wildmatch.sh'.
- Or 'test_cmp' is invoked in a loop, e.g. the test 'cvs update
(-p)' in 't9400-git-cvsserver-server.sh'.

The read_mailmap_buf function reads each line of the mailmap
using strchrnul, like:
const char *end = strchrnul(buf, '\n');
unsigned long linelen = end - buf + 1;
But that's off-by-one when we actually hit the NUL byte; our
line does not have a terminator, and so is only "end - buf"
bytes long. As a result, when we subtract the linelen from
the total len, we end up with (unsigned long)-1 bytes left
in the buffer, and we start reading random junk from memory.
We could fix it with:
unsigned long linelen = end - buf + !!*end;
but let's take a step back for a moment. It's questionable
in the first place for a function that takes a buffer and
length to be using strchrnul. But it works because we only
have one caller (and are only likely to ever have this one),
which is handing us data from read_sha1_file. Which means
that it's always NUL-terminated.
Instead of tightening the assumptions to make the
buffer/length pair work for a caller that doesn't actually
exist, let's let loosen the assumptions to what the real
caller has: a modifiable, NUL-terminated string.
This makes the code simpler and shorter (because we don't
have to correlate strchrnul with the length calculation),
correct (because the code with the off-by-one just goes
away), and more efficient (we can drop the extra allocation
we needed to create NUL-terminated strings for each line,
and just terminate in place).

"git commit --author=$name" sets the author to one whose name
matches the given string from existing commits, when $name is not in
the "Name <e-mail>" format. However, it does not honor the mailmap
to use the canonical name for the author found this way.
Fix it by telling the logic to find a matching existing author to
honor the mailmap, and use the name and email after applying the
mailmap.

The email addresses in the records read from the .mailmap file are
downcased very early, and then used to match against e-mail
addresses in the input. Because we do use case insensitive version
of string list to manage these entries, there is no need to do this,
and worse yet, downcasing the rewritten/canonical e-mail read from
the .mailmap file loses information.
Stop doing that, and also make the string list used to keep multiple
names for an mailmap entry case insensitive (the code that uses the
list, lookup_prefix(), expects a case insensitive match).

The email addresses read from .mailmap are downcased before being
inserted into the mailmap data structure, which undesirably loses
information. It is impossible, for instance, to map <first.last@host>
to <First.Last@host>. Demonstrate this problem.

In parse_name_and_email() function, there is this line:
*name = (nstart < nend ? nstart : NULL);
When the function is given a buffer "A <A@example.org> <old@x.z>",
nstart scans from the beginning of the buffer, skipping whitespaces
(there isn't any, so nstart points at the buffer), while nend starts
from one byte before the first '<' and skips whitespaces backwards
and stops at the first non-whitespace (i.e. it hits "A" at the
beginning of the buffer). nstart == nend in this case for a
single-letter name, and an off-by-one error makes it fail to pick up
the name, which makes the entry equivalent to
<A@example.org> <old@x.z>
without the name.

Currently you can use mailmap to display log authors and committers
but you can't use the mailmap to find commits with mapped values.
This commit allows you to run:
git log --use-mailmap --author mapped_name_or_email
git log --use-mailmap --committer mapped_name_or_email
Of course it only works if the --use-mailmap option is used.
The new name and email are copied only when necessary.

The motivation for mailmap.blob is to let users of bare
repositories use the mailmap feature, as they would not have
a checkout containing the .mailmap file. We can make it even
easier for them by just looking in HEAD:.mailmap by default.
We can't know for sure that this is where they would keep a
mailmap, of course, but it is the best guess (and it matches
the non-bare behavior, which reads from HEAD:.mailmap in the
working tree). If it's missing, git will silently ignore the
setting.
We do not do the same magic in the non-bare case, because:
1. In the common case, HEAD:.mailmap will be the same as
the .mailmap in the working tree, which is a no-op.
2. In the uncommon case, the user has modified .mailmap
but not yet committed it, and would expect the working
tree version to take precedence.

In a bare repository, there isn't a simple way to respect an
in-tree mailmap without extracting it to a temporary file.
This patch provides a config variable, similar to
mailmap.file, which reads the mailmap from a blob in the

The "shortlog" command defaults to HEAD only when its standard input is
connected to a terminal; otherwise it acts in the traditional "filter"
mode to read and summarize the "git log" output.
Two new tests added to t4203 assumed that the command always default to
HEAD, but when the standard input is closed (or connected to /dev/null),
it output empty, which is a summary of its empty input, causing the test
to break.
