cddb42d2c5 rebase -i -p: document shortcomings
The rebase --preserve-merges facility presents a list of commits
in its instruction sheet and uses a separate table to keep
track of their parents.  Unfortunately, in practice this means
that with -p after most attempts to rearrange patches, some
commits have the "wrong" parent and the resulting history is
rarely what the caller expected.

Yes, it would be nice to fix that.  But first, add a warning to the
manual to help the uninitiated understand what is going on.

b499549401 Teach rebase the --no-ff option.
For git-rebase.sh, --no-ff is a synonym for --force-rebase.

For git-rebase--interactive.sh, --no-ff cherry-picks all the commits in
the rebased branch, instead of fast-forwarding over any unchanged commits.

--no-ff offers an alternative way to deal with reverted merges.  Instead of
"reverting the revert" you can use "rebase --no-ff" to recreate the branch
with entirely new commits (they're new because at the very least the
committer time is different).  This obviates the need to revert the
reversion, as you can re-merge the new topic branch directly.  Added an
addendum to revert-a-faulty-merge.txt describing the situation and how to
use --no-ff to handle it.

2ec33cdd19 rebase--interactive: don't require what's rebased to be a branch
git rebase allows you to specify a non-branch commit-ish as the "branch"
argument, which leaves HEAD detached when it's finished.  This is
occasionally useful, and this patch brings the same functionality to git

6bdcd0d2fc rebase -i: Retain user-edited commit messages after squash/fixup conflicts
When a squash/fixup fails due to a conflict, the user is required to
edit the commit message.  Previously, if further squash/fixup commands
followed the conflicting squash/fixup, this user-edited message was
discarded and a new automatically-generated commit message was
suggested.

Change the handling of conflicts within squash/fixup command series:
Whenever the user is required to intervene, consider the resulting
commit to be a new basis for the following squash/fixups and use its
commit message in later suggested combined commit messages.

So avoid passing an empty parameter to "git commit".

Attempting to rebase three-commit series (two regular changes, followed by
one commit that changes what commit is bound for a submodule path) to
squash the first two results in a failure; not just the first two commits
squashed, but the change to the submodule is also included in the result.

This failure causes the subsequent step to "pick" the change that actually
changes the submodule to be applied, because there is no change left to be
applied.

In case there is no commit to apply (for example because you rebase to

Do this by introducing a new command, "noop", which is substituted for

5352a82bab t3404: test two "preserve merges with -p" cases
There are two cases for preserving merges:

  1. The merge base is outside the trunk that is to be rebased.
     Then commits of those other parents must not be picked.

  2. The merge base is inside the trunk that is to be rebased.
     Then all the commits related to that merge must be picked
     and the merge must be redone.

The "preserve merges with -p" test case tested for case 1 only.
This patch adds case 2.

f69e836fab Fix tests breaking when checkout path contains shell metacharacters
This fixes the remainder of the issues where the test script itself is at
fault for failing when the git checkout path contains whitespace or other
shell metacharacters.

The majority of git svn tests used the idiom

  test_expect_success "title" "test script using $svnrepo"

These were changed to have the test script in single-quotes:

  test_expect_success "title" 'test script using "$svnrepo"'

which unfortunately makes the patch appear larger than it really is.

One consequence of this change is that in the verbose test output the
value of $svnrepo (and in some cases other variables, too) is no
longer expanded, i.e. previously we saw

  * expecting success:
	test script using /path/to/git/t/trash/svnrepo

but now it is:

  * expecting success:
	test script using "$svnrepo"

82ebb0b6ec add test_cmp function for test scripts
Many scripts compare actual and expected output using
"diff -u". This is nicer than "cmp" because the output shows
how the two differ. However, not all versions of diff
understand -u, leading to unnecessary test failure.

This adds a test_cmp function to the test scripts and
switches all "diff -u" invocations to use it. The function
uses the contents of "$GIT_TEST_CMP" to compare its
arguments; the default is "diff -u".

On systems with a less-capable diff, you can do:

  GIT_TEST_CMP=cmp make test

aadbe44f88 grep portability fix: don't use "-e" or "-q"
System V versions of grep (such as Solaris /usr/bin/grep)
don't understand either of these options. git's usage of
"grep -e pattern" fell into one of two categories:

 1. equivalent to "grep pattern". -e is only useful here if
    the pattern begins with a "-", but all of the patterns
    are hardcoded and do not begin with a dash.

 2. stripping comments and blank lines with

      grep -v -e "^$" -e "^#"

    We can fortunately do this in the affirmative as

      grep '^[^#]'

Uses of "-q" can be replaced with redirection to /dev/null.
In many tests, however, "grep -q" is used as "if this string
is in the expected output, we are OK". In this case, it is
fine to just remove the "-q" entirely; it simply makes the
"verbose" mode of the test slightly more verbose.

7cf7f54a65 use build-time SHELL_PATH in test scripts
The top-level Makefile now creates a GIT-BUILD-OPTIONS file
which stores any options selected by the make process that
may be of use to further parts of the build process.
Specifically, we store the SHELL_PATH so that it can be used
by tests to construct shell scripts on the fly.

The format of the GIT-BUILD-OPTIONS file is Bourne shell,
and it is sourced by test-lib.sh; all tests can rely on just
having $SHELL_PATH correctly set in the environment.

The GIT-BUILD-OPTIONS file is written every time the
toplevel 'make' is invoked. Since the only users right now
are the test scripts, there's no drawback to updating its
timestamp. If something build-related depends on this, we
can do a trick similar to the one used by GIT-CFLAGS.

that the user would call "git commit --amend" herself.

But we can be nice and do that for the user.

1d25c8cf82 rebase -i: fix squashing corner case
When squashing, rebase -i did not prevent fast forwards.  This could
happen when picking some other commit than the first one, and then
squashing the first commit.  So do not allow fast forwards when
squashing.

77b258f436 t3404: fix "fake-editor"
Here-text to create fake-editor did not use <<\EOF but <<EOF,
but there was no point doing so, as it quoted all the variables
anyway.  Simplify it.

Also futureproof the special mode to edit COMMIT_EDITMSG file;
it is interested in editing the COMMIT_EDITMSG file in any
GIT_DIR; GIT_DIR may be given as an absolute path.
