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.

Fix a bug in the matching routine powering -S<rx> --pickaxe-regex so
that we won't abort early on content that has NULs in it.
We've had a hard requirement on REG_STARTEND since 2f8952250a8 (regex:
add regexec_buf() that can work on a non NUL-terminated string,
2016-09-21), but this sanity check dates back to d01d8c67828 (Support
for pickaxe matching regular expressions, 2006-03-29).
It wasn't needed anymore, and as the now-passing test shows, actively
getting in our way. Since we always require REG_STARTEND support we do
not need to stop at NULs. If we are dealing with a haystack with NUL
in it. The needle may be behind that NUL.

Assert early in diffcore_pickaxe() that we've got a needle to work
with under -G and -S.
This code is redundant to the check -G and -S get from
parse-options.c's get_arg(), which I'm adding a test for.
This check dates back to e1b161161d (diffcore-pickaxe: fix infinite
loop on zero-length needle, 2007-01-25) when "git log -S" could send
this code into an infinite loop.
It was then later refactored in 8fa4b09fb1 (pickaxe: hoist empty
needle check, 2012-10-28) into its current form, but it seemingly
wasn't noticed that in the meantime a move to the parse-options.c API
in dea007fb4c (diff: parse separate options like -S foo, 2010-08-05)
had made it redundant.
Let's retain some of the paranoia here with a BUG(), but there's no
need to be checking this in the pickaxe_match() inner loop.

Neither the --pickaxe-all documentation nor --find-object's has ever
suggested that you can combine the two. See f506b8e8b5 (git log/diff:
add -G<regexp> that greps in the patch text, 2010-08-23) and
15af58c1ad (diffcore: add a pickaxe option to find a specific blob,
2018-01-04).
But we've silently tolerated it, which makes the logic in
diffcore_pickaxe() harder to reason about. Let's assert that we won't
have the two combined.

When the -G and --pickaxe-regex options are combined we simply ignore
the --pickaxe-regex option. Let's die instead as suggested by our
documentation, since -G is always a regex.
When --pickaxe-regex was added in d01d8c6782 (Support for pickaxe
matching regular expressions, 2006-03-29) only the -S option
existed. Then when -G was added in f506b8e8b5 (git log/diff: add
-G<regexp> that greps in the patch text, 2010-08-23) neither the
documentation for --pickaxe-regex was updated accordingly, nor was
something like this assertion added.
Since 5bc3f0b567 (diffcore-pickaxe doc: document -S and -G properly,
2013-05-31) we've claimed that --pickaxe-regex should only be used
with -S, but have silently tolerated combining it with -G, let's die
instead.

Add a missing test for --no-pickaxe-regex. This has been an error ever
since before the -S or -G options were added, or since
7ae0b0cb65f (git-log (internal): more options., 2006-03-01).
The reason for adding this test is that Junio suggested in [1] in
response to a later test addition in this series that it might be good
to support --no-pickaxe-regex in combination with -G. This would allow
for fixed-string searching with -G, similr to grep's --fixed-strings
mode.
I agree that that would make sense if anyone would like to implement
it, but since it dies right now let's first add this test to assert
the existing long-standing behavior. We can always add support for
--[no-]pickaxe-regex in combination with -G at some later date.

In diffgrep_consume() we generate a diff, and then advance past the
"+" or "-" at the start of the line for matching. This has been done
ever since the code was added in f506b8e8b5f (git log/diff: add
-G<regexp> that greps in the patch text, 2010-08-23).
If we match "line" instead of "line + 1" no tests fail, i.e. we've got
zero coverage for whether any of our searches match the beginning of
the line or not. Let's add a test for this.

Refactor the existing tests added in e0e7cb8080c (log -G: ignore
binary files, 2018-12-14) to use the --append option I added in
3373518cc8b (test-lib functions: add an --append option to
test_commit, 2021-01-12) and the --printf option added as part of an
in-flight topic of mine this commit depends on.
While I'm at it change some of the setup of the test to use a more
sensible pattern, e.g. setting up a temporary repo instead of creating
an orphan branch.
Since the -G and -S options will behave the same way with truncated
and removed content also change the "git rm" to emptying data.bin,
that's just catering to how test_commit works. The resulting test is
shorter.
See also f5d79bf7dd6 (tests: refactor a few tests to use "test_commit
--append", 2021-01-12) for prior similar refactoring.

The -G<regex> option of log looks for the differences whose patch text
contains added/removed lines that match regex.
Currently -G looks also into patches of binary files (which
according to [1]) is binary as well.
This has a couple of issues:
- It makes the pickaxe search slow. In a proprietary repository of the
author with only ~5500 commits and a total .git size of ~300MB
searching takes ~13 seconds
$time git log -Gwave > /dev/null
real 0m13,241s
user 0m12,596s
sys 0m0,644s
whereas when we ignore binary files with this patch it takes ~4s
$time ~/devel/git/git log -Gwave > /dev/null
real 0m3,713s
user 0m3,608s
sys 0m0,105s
which is a speedup of more than fourfold.
- The internally used algorithm for generating patch text is based on
xdiff and its states in [1]
> The output format of the binary patch file is proprietary
> (and binary) and it is basically a collection of copy and insert
> commands [..]
which means that the current format could change once the internal
algorithm is changed as the format is not standardized. In addition
the git binary patch format used for preparing patches for git apply
is *different* from the xdiff format as can be seen by comparing

which seems unexpected.
To resolve these issues this patch makes -G<regex> ignore binary files
by default. Textconv filters are supported and also -a/--text for
getting the old and broken behaviour back.
The -S<block of text> option of log looks for differences that changes
the number of occurrences of the specified block of text (i.e.
addition/deletion) in a file. As we want to keep the current behaviour,
add a test to ensure it stays that way.

Reduce code duplication by introducing test_log_icase() that runs the

"git log -S<string>" is a useful way to find the last commit in the
codebase that touched the <string>. As it was designed to be used by a
porcelain script to dig the history starting from a block of text that
appear in the starting commit, it never had to look for anything but an
exact match.
When used by an end user who wants to look for the last commit that
removed a string (e.g. name of a variable) that he vaguely remembers,
however, it is useful to support case insensitive match.
When given the "--regexp-ignore-case" (or "-i") option, which originally
was designed to affect case sensitivity of the search done in the commit
log part, e.g. "log --grep", the matches made with -S/-G pickaxe search is
done case insensitively now.
