980b482d28 ("rebase tests: mark tests specific to the am-backend with
--am", 2020-02-15) sought to prepare tests testing the "apply" backend
in preparation for 2ac0d6273f ("rebase: change the default backend
from "am" to "merge"", 2020-02-15). However some tests seem to have
been missed leading to us testing the "merge" backend twice. This
patch fixes some cases that I noticed while adding tests to these
files, I have not audited all the other rebase test files. I've
reworded a couple of the test descriptions to make it clear which
backend they are testing.

Setting GIT_AUTHOR_* when committing with --amend will only change the
author if we also pass --reset-author. This commit is used in some
tests that ensure the author ident does not change when rebasing.
Creating this commit without changing the authorship meant that the
test would not catch regressions that caused rebase to discard the
original authorship information.

It is useful for performance monitoring and debugging purposes to know
the wire protocol used for remote operations. This may differ from the
version set in local configuration due to differences in version and/or
configuration between the server and the client. Therefore, log the
negotiated wire protocol version via trace2, for both clients and
servers.

We parse through binary hunks by looping through the buffer with code
like:
llen = linelen(buffer, size);
...do something with the line...
buffer += llen;
size -= llen;
However, before we enter the loop, there is one call that increments
"buffer" but forgets to decrement "size". As a result, our "size" is off
by the length of that line, and subsequent calls to linelen() may look
past the end of the buffer for a newline.
The fix is easy: we just need to decrement size as we do elsewhere.
This bug goes all the way back to 0660626caf (binary diff: further
updates., 2006-05-05). Presumably nobody noticed because it only
triggers if the patch is corrupted, and even then we are often "saved"
by luck. We use a strbuf to store the incoming patch, so we overallocate
there, plus we add a 16-byte run of NULs as slop for memory comparisons.
So if this happened accidentally, the common case is that we'd just read
a few uninitialized bytes from the end of the strbuf before producing
the expected "this patch is corrupted" error complaint.
However, it is possible to carefully construct a case which reads off
the end of the buffer. The included test does so. It will pass both
before and after this patch when run normally, but using a tool like
ASan shows that we get an out-of-bounds read before this patch, but not
after.

As we iterate through the buffer containing git-log output, parsing
lines, we use an "int" to store the size of an individual line. This
should be a size_t, as we have no guarantee that there is not a
malicious 2GB+ commit-message line in the output.
Overflowing this integer probably doesn't do anything _too_ terrible. We
are not using the value to size a buffer, so the worst case is probably
an out-of-bounds read from before the array. But it's easy enough to
fix.
Note that we have to use ssize_t here, since we also store the length
result from parse_git_diff_header(), which may return a negative value
for error. That function actually returns an int itself, which has a
similar overflow problem, but I'll leave that for another day. Much
of the apply.c code uses ints and should be converted as a whole; in the
meantime, a negative return from parse_git_diff_header() will be
interpreted as an error, and we'll bail (so we can't handle such a case,
but given that it's likely to be malicious anyway, the important thing
is we don't have any memory errors).

When parsing our buffer of output from git-log, we have a
find_end_of_line() helper that finds the next newline, and gives us the
number of bytes to move past it, or the size of the whole remaining
buffer if there is no newline.
But trying to handle both those cases leads to some oddities:
- we try to overwrite the newline with NUL in the caller, by writing
over line[len-1]. This is at best redundant, since the helper will
already have done so if it saw a newline. But if it didn't see a
newline, it's actively wrong; we'll overwrite the byte at the end of
the (unterminated) line.
We could solve this just dropping the extra NUL assignment in the
caller and just letting the helper do the right thing. But...
- if we see a "diff --git" line, we'll restore the newline on top of
the NUL byte, so we can pass the string to parse_git_diff_header().
But if there was no newline in the first place, we can't do this.
There's no place to put it (the current code writes a newline
over whatever byte we obliterated earlier). The best we can do is
feed the complete remainder of the buffer to the function (which is,
in fact, a string, by virtue of being a strbuf).
To solve this, the caller needs to know whether we actually found a
newline or not. We could modify find_end_of_line() to return that
information, but we can further observe that it has only one caller.
So let's just inline it in that caller.
Nobody seems to have noticed this case, probably because git-log would
never produce input that doesn't end with a newline. Arguably we could
just return an error as soon as we see that the output does not end in a
newline. But the code to do so actually ends up _longer_, mostly because
of the cleanup we have to do in handling the error.

The "offset" variable was was introduced in 44b67cb62b (range-diff:
split lines manually, 2019-07-11), but it has never done anything
useful. We use it to count up the number of bytes we've consumed, but we
never look at the result. It was probably copied accidentally from an
almost-identical loop in apply.c:find_header() (and the point of that
commit was to make use of the parse_git_diff_header() function which
underlies both).
Because the variable was set but not used, most compilers didn't seem to
notice, but the upcoming clang-14 does complain about it, via its
-Wunused-but-set-variable warning.

This reverts commit f5bfcc823b, which
made "git log -m" imply "--patch" by default. The logic was that
"-m", which makes diff generation for merges perform a diff against
each parent, has no use unless I am viewing the diff, so we could save
the user some typing by turning on display of the resulting diff
automatically. That wasn't expected to adversely affect scripts
because scripts would either be using a command like "git diff-tree"
that already emits diffs by default or would be combining -m with a
diff generation option such as --name-status. By saving typing for
interactive use without adversely affecting scripts in the wild, it
would be a pure improvement.
The problem is that although diff generation options are only relevant
for the displayed diff, a script author can imagine them affecting
path limiting. For example, I might run
git log -w --format=%H -- README
hoping to list commits that edited README, excluding whitespace-only
changes. In fact, a whitespace-only change is not TREESAME so the use
of -w here has no effect (since we don't apply these diff generation
flags to the diff_options struct rev_info::pruning used for this
purpose), but the documentation suggests that it should work
Suppose you specified foo as the <paths>. We shall call
commits that modify foo !TREESAME, and the rest TREESAME. (In
a diff filtered for foo, they look different and equal,
respectively.)
and a script author who has not tested whitespace-only changes
wouldn't notice.
Similarly, a script author could include
git log -m --first-parent --format=%H -- README
to filter the first-parent history for commits that modified README.
The -m is a no-op but it reflects the script author's intent. For
example, until 1e20a407fe (stash list: stop passing "-m" to "git
log", 2021-05-21), "git stash list" did this.
As a result, we can't safely change "-m" to imply "-p" without fear of
breaking such scripts. Restore the previous behavior.
Noticed because Rust's src/bootstrap/bootstrap.py made use of this
same construct: https://github.com/rust-lang/rust/pull/87513. That
script has been updated to omit the unnecessary "-m" option, but we
can expect other scripts in the wild to have similar expectations.

commonly expected will trigger warnings with pedantic on both
clang[-Wextra-semi] and gcc[-Wpedantic], because that macro has already
a semicolon and is meant to be invoked without one.
while fixing the macro would be a worthy solution (specially considering
this is a common recurring problem), remove the extra ';' for now to

gcc version 10.2.1 20210110 (Debian 10.2.1-6)
