Brian Gesiak 4f4074077f rebase: allow "-" short-hand for the previous branch
Teach rebase the same shorthand as checkout and merge to name the
branch to rebase the current branch on; that is, that "-" means "the
branch we were previously on".

John Keeping bb3f45838b rebase: fix fork-point with zero arguments
When no arguments are specified, $switch_to is empty so we end up
passing the empty string to "git merge-base --fork-point", which causes
an error.  git-rebase carries on at this point, but in fact we have
failed to apply the fork-point operation.

It turns out that the test in t3400 that was meant to test this didn't
actually need the fork-point behaviour, so enhance it to make sure that
the fork-point is applied correctly.  The modified test fails without
the change to git-rebase.sh in this patch.

John Keeping ad8261d212 rebase: use reflog to find common base with upstream
Commit 15a147e (rebase: use @{upstream} if no upstream specified,
2011-02-09) says:

	Make it default to 'git rebase @{upstream}'. That is also what
	'git pull [--rebase]' defaults to, so it only makes sense that
	'git rebase' defaults to the same thing.

but that isn't actually the case.  Since commit d44e712 (pull: support
rebased upstream + fetch + pull --rebase, 2009-07-19), pull has actually
chosen the most recent reflog entry which is an ancestor of the current
branch if it can find one.

Add a '--fork-point' argument to git-rebase that can be used to trigger
this behaviour.  This option is turned on by default if no non-option
arguments are specified on the command line, otherwise we treat an
upstream specified on the command-line literally.

2013-04-26 15:28:34 -07:00
Phil Hord ea70980030 rebase: find orig_head unambiguously
When we 'git rebase $upstream', git uses 'rev-parse --verify
$current_branch' to find ORIG_HEAD.  But if $current_branch
is ambiguous, 'rev-parse --verify' emits a warning and returns
a SHA1 anyway.  When the wrong ambiguous choice is used,
git-rebase fails non-gracefully:  it emits a warning about
failing to lock $current_branch, an error about being unable to
checkout $current_branch again, and it might even decide the
rebase is a fast-forward when it is not.

In the 'rebase $upstream' case, we already know the unambiguous
spelling of $current_branch is "HEAD".  Fix git-rebase to find
$orig_head unambiguously.

Add a test in t3400-rebase.sh which creates an ambiguous branch
name and rebases it implicitly with 'git rebase $other'.

The current message is too long and at too low a level for anybody
to understand it if they don't know about the configuration format
already.

The text about setting up a remote is superfluous and doesn't help
understand or recover from the error that has happened.  Show the
usage more prominently and explain how to set up the tracking
information. If there is only one remote, that name is used instead
of the generic <remote>.

Also simplify the message we print on detached HEAD to remove
unnecessary information which is better left for the documentation.

Junio C Hamano 2c733fb24c parse_date(): '@' prefix forces git-timestamp
The only place that the issue this series addresses was observed
where we read "cat-file commit" output and put it in GIT_AUTHOR_DATE
in order to replay a commit with an ancient timestamp.

With the previous patch alone, "git commit --date='20100917 +0900'"
can be misinterpreted to mean an ancient timestamp, not September in
year 2010.  Guard this codepath by requring an extra '@' in front of
the raw git timestamp on the parsing side. This of course needs to
be compensated by updating get_author_ident_from_commit and the code
for "git commit --amend" to prepend '@' to the string read from the
existing commit in the GIT_AUTHOR_DATE environment variable.

Martin von Zweigbergk 15a147e618 rebase: use @{upstream} if no upstream specified
'git rebase' without arguments is currently not supported. Make it
default to 'git rebase @{upstream}'. That is also what 'git pull
[--rebase]' defaults to, so it only makes sense that 'git rebase'
defaults to the same thing.

Defaulting to @{upstream} will make it possible to run e.g. 'git
rebase -i' without arguments, which is probably a quite common use
case. It also improves the scenario where you have multiple branches
that rebase against a remote-tracking branch, where you currently have
to choose between the extra network delay of 'git pull' or the
slightly awkward keys to enter 'git rebase @{u}'.

The error reporting when no upstream is configured for the current
branch or when no branch is checked out is reused from git-pull.sh. A
function is extracted into git-parse-remote.sh for this purpose.

Matthieu Moy e6c111b4c0 unpack_trees: group error messages by type
When an error is encountered, it calls add_rejected_file() which either
- directly displays the error message and stops if in plumbing mode
  (i.e. if show_all_errors is not initialized at 1)
- or stores it so that it will be displayed at the end with display_error_msgs(),

Storing the files by error type permits to have a list of files for
which there is the same error instead of having a serie of almost
identical errors.

As each bind_overlap error combines a file and an old file, a list cannot be
done, therefore, theses errors are not stored but directly displayed.

Junio C Hamano 840b3ca758 rebase: protect against diff.renames configuration
We currently do not disable diff.renames configuration while rebase
internally runs "format-patch" to feed "am -3".

The end user configuration for "diff" should not affect the result
produced by the higher level command that is related to "diff" only
because internally it is implemented in terms of it.

For that matter, I have a feeling that format-patch should not even look
at diff.renames, but we seem to have been doing this for a long time so
there is no easy way to fix this thinko.

In any case, here is a much straightforward fix for "rebase".

Jay Soffian 43c23251f9 am: use get_author_ident_from_commit instead of mailinfo when rebasing
In certain situations, commit authorship can consist of an invalid
e-mail address. For example, this is the case when working with git svn
repos where the author email has had the svn repo UUID appended such as:

 author@example.com <author@example.com@deadbeef-dead-beef-dead-beefdeadbeef>

Given such an address, mailinfo extracts the authorship incorrectly as
it assumes a valid domain. However, when rebasing the original
authorship should be preserved irrespective of its validity as an email
address.

Using get_author_ident_from_commit instead of mailinfo when rebasing
preserves the original authorship.

Johannes Sixt 1f553918a8 test-lib: Introduce test_chmod and use it instead of update-index --chmod
This function replaces sequences of 'chmod +x' and 'git update-index
--chmod=+x' in the test suite, whose purpose is to help filesystems
that need core.filemode=false. Two places where only 'chmod +x' was used
we also use this new function.

The function calls 'git update-index --chmod' without checking
core.filemode (unlike some of the call sites did). We do this because the
call sites *expect* that the executable bit ends up in the index (ie. it
is not the purpose of the call sites to *test* whether git treats
'chmod +x' and 'update-index --chmod=+x' correctly). Therefore, on
filesystems with core.filemode=true the 'git update-index --chmod' is a
no-op.

The function uses --add with update-index to help one call site in
t6031-merge-recursive. It makes no difference for the other callers.

Johannes Sixt 2559bff32c t3400-rebase: Move detached HEAD check earlier
Short story: There is a section in t3400 that tests fundamental rebase
properties.  3ec7371f (Add two extra tests for git rebase, 2009-02-09)
added a check that rebase works on a detached HEAD, but the test was put
near the end of the file.  This moves it to a more suitable place.

Long story: The test that preceded the one in question tests that a
rebased commit degrades from a content change with mode change to a
mere mode change.  But on Windows, where we have core.filemode=false,
the original commit did not record the mode change, and so the rebase
operation did not rebase anything.  This caused the subsequent detached
HEAD test to fail.

Junio C Hamano 41ac414ea2 Sane use of test_expect_failure
Originally, test_expect_failure was designed to be the opposite
of test_expect_success, but this was a bad decision.  Most tests
run a series of commands that leads to the single command that
needs to be tested, like this:

    test_expect_{success,failure} 'test title' '
	setup1 &&
        setup2 &&
        setup3 &&
        what is to be tested
    '

And expecting a failure exit from the whole sequence misses the
point of writing tests.  Your setup$N that are supposed to
succeed may have failed without even reaching what you are
trying to test.  The only valid use of test_expect_failure is to
check a trivial single command that is expected to fail, which
is a minority in tests of Porcelain-ish commands.

This large-ish patch rewrites all uses of test_expect_failure to
use test_expect_success and rewrites the condition of what is
tested, like this:

    test_expect_success 'test title' '
	setup1 &&
        setup2 &&
        setup3 &&
        ! this command should fail
    '

test_expect_failure is redefined to serve as a reminder that
that test *should* succeed but due to a known breakage in git it
currently does not pass.  So if git-foo command should create a
file 'bar' but you discovered a bug that it doesn't, you can
write a test like this:

    test_expect_failure 'git-foo should create bar' '
        rm -f bar &&
        git foo &&
        test -f bar
    '

This construct acts similar to test_expect_success, but instead
of reporting "ok/FAIL" like test_expect_success does, the
outcome is reported as "FIXED/still broken".

Johannes Schindelin ece7b74903 apply --index-info: fall back to current index for mode changes
"git diff" does not record index lines for pure mode changes (i.e. no
lines changed).  Therefore, apply --index-info would call out a bogus
error.

Instead, fall back to reading the info from the current index.

Incidentally, this fixes an error where git-rebase would not rebase a
commit including a pure mode change, and changes requiring a threeway
merge.

Noticed and later tested by Chris Shoemaker.

Johannes Sixt 1308c17b3e Allow rebase to run if upstream is completely merged
Consider this history:

  o--o-...-B          <- origin
      \     \
       x--x--M--x--x  <- master

In this situation, rebase considers master fully up-to-date and would
not do anything. However, if there were additional commits on origin,
the rebase would run and move the commits x on top of origin.

Here we change rebase to short-circuit out only if the history since origin
is strictly linear. Consequently, the above as well as a history like this
would be linearized:

  o--o               <- origin
      \
       x--x
        \  \
         x--M--x--x  <- master

Amos Waterland 294c695d8c git rebase loses author name/email if given bad email address
If GIT_AUTHOR_EMAIL is of a certain form, `git rebase master' will blow
away the author name and email when fast-forward merging commits.  I
have not tracked it down, but here is a testcase that demonstrates the
behavior.
