cf3983d1ff log: fix indentation for --graph --show-signature
The git log --graph --show-signature command incorrectly indents the gpg
information about signed commits and merged signed tags. It does not
follow the level of indentation of the current commit.

45067fc973 t7300: repair filesystem permissions with test_when_finished
We create a directory that cannot be removed, confirm that
it cannot be removed, and then fix it like:

  chmod 0 foo &&
  test_must_fail git clean -d -f &&
  chmod 755 foo

If the middle step fails but leaves the directory (e.g., the
bug is that clean does not notice the failure), this
pollutes the test repo with an unremovable directory. Not
only does this cause further tests to fail, but it means
that "rm -rf" fails on the whole trash directory, and the
user has to intervene manually to even re-run the test script.

We can bump the "chmod 755" recovery to a test_when_finished
block to be sure that it always runs.

80b47854ca sha1_file: avoid overrunning alternate object base string
While checking if a new alternate object database is a duplicate make
sure that old and new base paths have the same length before comparing
them with memcmp.  This avoids overrunning the buffer of the existing
entry if the new one is longer and it stops rejecting foobar/ after
foo/ was already added.

79bc4ef368 filter-branch: eliminate duplicate mapped parents
When multiple parents of a merge commit get mapped to the same
commit, filter-branch used to pass all instances of the parent
commit to the parent and commit filters and to "git commit-tree" or
"git_commit_non_empty_tree".

This can often happen when extracting a small project from a large
repository; merges can join history with no commits on any branch
which affect the paths being retained.  Once the intermediate
commits have been filtered out, all the immediate parents of the
merge commit can end up being mapped to the same commit - either the
original merge-base or an ancestor of it.

"git commit-tree" would display an error but write the commit with
the normalized parents in any case.  "git_commit_non_empty_tree"
would fail to notice that the commit being made was in fact a
non-merge commit and would retain it even if a further pass with
"--prune-empty" would discard the commit as empty.

Ensure that duplicate parents are pruned before the parent filter to
make "--prune-empty" idempotent, removing all empty non-merge
commits in a singe pass.

958b2eb26c move "%G" format test from t7510 to t6006
The final test in t7510 checks that "--format" placeholders
that look similar to GPG placeholders (but that we don't
actually understand) are passed through. That test was
placed in t7510, since the other GPG placeholder tests are
there. However, it does not have a GPG prerequisite, because
it is not actually checking any signed commits.

This causes the test to erroneously fail when gpg is not
installed on a system, however. Not because we need signed
commits, but because we need _any_ commit to run "git log".
If we don't have gpg installed, t7510 doesn't create any
commits at all.

We can fix this by moving the test into t6006. This is
arguably a better place anyway, because it is where we test
most of the other placeholders (we do not test GPG
placeholders there because of the infrastructure needed to
make signed commits).

If the user asks for --format=%G with nothing else, we
correctly realize that "%G" is not a valid placeholder (it
should be "%G?", "%GK", etc). But we still tell the
strbuf_expand code that we consumed 2 characters, causing it
to jump over the trailing NUL and output garbage.

This also fixes the case where "%GX" would be consumed (and
produce no output). In other cases, we pass unrecognized
placeholders through to the final string.

7b1732c116 t7510: use consistent &&-chains in loop
We check multiple commits in a loop. Because we want to
break out of the loop if any single iteration fails, we use
a subshell/exit like:

  (
	for i in $stuff
	do
		do-something $i || exit 1
	done
  )

However, we are inconsistent in our loop body. Some commands
get their own "|| exit 1", and others try to chain to the
next command with "&&", like:

  X &&
  Y || exit 1
  Z || exit 1

This is a little hard to read and follow, because X and Y
are treated differently for no good reason. But much worse,
the second loop follows a similar pattern and gets it wrong.
"Y" is expected to fail, so we use "&& exit 1", giving us:

  X &&
  Y && exit 1
  Z || exit 1

That gets the test for X wrong (we do not exit unless both X
fails and Y unexpectedly succeeds, but we would want to exit
if _either_ is wrong). We can write this clearly and
correctly by consistently using "&&", followed by a single
"|| exit 1", and negating Y with "!" (as we would in a
normal &&-chain). Like:

  X &&
  ! Y &&
  Z || exit 1

If git rebase --merge encountered a conflict, --skip would not work if the
next commit also conflicted.  The msgnum file would never be updated with
the new patch number, so no patch would actually be skipped, resulting in an
inescapable loop.

Update the msgnum file's value as the first thing in call_merge.  This also
avoids an "Already applied" message when skipping a commit.  There is no
visible change for the other contexts in which call_merge is invoked, as the
msgnum file's value remains unchanged in those situations.

97c1364be6 t0008: do not depend on 'echo' handling backslashes specially
The original used to pass with /bin/dash but not with /bin/bash set
to $SHELL_PATH.  The former turns "\\" into "\", but the latter does
not.

218aa3a616 reuse cached commit buffer when parsing signatures
When we call show_signature or show_mergetag, we read the
commit object fresh via read_sha1_file and reparse its
headers. However, in most cases we already have the object
data available, attached to the "struct commit". This is
partially laziness in dealing with the memory allocation
issues, but partially defensive programming, in that we
would always want to verify a clean version of the buffer
(not one that might have been munged by other users of the
commit).

However, we do not currently ever munge the commit buffer,
and not using the already-available buffer carries a fairly
big performance penalty when we are looking at a large
number of commits. Here are timings on linux.git:

  [baseline, no signatures]
  $ time git log >/dev/null
  real    0m4.902s
  user    0m4.784s
  sys     0m0.120s

  [before]
  $ time git log --show-signature >/dev/null
  real    0m14.735s
  user    0m9.964s
  sys     0m0.944s

  [after]
  $ time git log --show-signature >/dev/null
  real    0m9.981s
  user    0m5.260s
  sys     0m0.936s

Note that our user CPU time drops almost in half, close to
the non-signature case, but we do still spend more
wall-clock and system time, presumably from dealing with
gpg.

An alternative to this is to note that most commits do not
have signatures (less than 1% in this repo), yet we pay the
re-parsing cost for every commit just to find out if it has
a mergetag or signature. If we checked that when parsing the
commit initially, we could avoid re-examining most commits
later on. Even if we did pursue that direction, however,
this would still speed up the cases where we _do_ have
signatures. So it's probably worth doing either way.

8597ea3afe commit: record buffer length in cache
Most callsites which use the commit buffer try to use the
cached version attached to the commit, rather than
re-reading from disk. Unfortunately, that interface provides
only a pointer to the NUL-terminated buffer, with no
indication of the original length.

For the most part, this doesn't matter. People do not put
NULs in their commit messages, and the log code is happy to
treat it all as a NUL-terminated string. However, some code
paths do care. For example, when checking signatures, we
want to be very careful that we verify all the bytes to
avoid malicious trickery.

This patch just adds an optional "size" out-pointer to
get_commit_buffer and friends. The existing callers all pass
NULL (there did not seem to be any obvious sites where we
could avoid an immediate strlen() call, though perhaps with
some further refactoring we could).
