The rough structure of run_rewrite_hook() comes from
run_receive_hook() in receive-pack.
We introduce a --no-post-rewrite option and use it to avoid the hook
when called from git-rebase -i 'edit'. The next patch will add full
support in git-rebase, and we only want to invoke the hook once.

This defines the behaviour of the post-rewrite hook support, which
will be implemented in the following patches.
We deliberately do not document how often the hook will be invoked per
rewriting command, but the interface is designed to keep that at
"once". This would currently not matter too much, since both rebase
and filter-branch are shellscripts and spawn many processes anyway.
However, when a fast sequencer in C is implemented, it will be
beneficial to only have to run the hook once.

git submodule summary: Handle HEAD as argument when on an unborn branch
When calling "git submodule summary HEAD" on an unborn branch the output
was empty even when it shouldn't have been ("git submodule summary"
without the HEAD argument prints the expected output since commit
"submodule summary: do not fail before the first commit").
This also fixes "git status" to emit the "Submodule changes to be
committed" section on an unborn branch when used with the
status.submodulesummary config option.

Given that "git show" always shows some diff and does not walk the history
by default, it is natural to expect "git show --first-parent" to show the
difference between the given commit and its first parent. It also would
be natural, given that "--cc" is the default, "git show -m" to show
pairwise difference from each of the parents.
We however always defaulted to --cc and there was no way to turn it off.
Traditionally, "show" defaulted to "show --cc" (dense combined patch), but
asking for combined patch with "show -c" didn't turn the patch output
format on; the placement of this logic in setup_revisions() dates back to cd2bdc5 (Common option parsing for "git log --diff" and friends,
2006-04-14).
This unfortunately cannot be done as a trivial change of "if dense
combined is asked, default to patch format" done in setup_revisions() to
"if any combined is asked, default to patch format", as "diff-tree -c"
needs to default to raw, while "diff-tree --cc" needs to default to patch,
and they share the codepath. These command specific defaults are now
handled in the new "tweak" callback that can be customized by individual
command implementations.
So far the last parameter to setup_revisions() was to specify the default
ref when the command line did not give any (typically "HEAD"). This changes
it to take a pointer to a structure so that we can add other information without
touching too many codepaths in later patches.
There's no way to override the sendemail.to, sendemail.cc, and
sendemail.bcc config settings. Add options allowing the user to tell
git to ignore the config settings and take whatever is on the command
line.

format-patch: add --no-cc, --no-to, and --no-add-headers
These new options allow users to override their config settings for

only make git ignore the config settings and any previous command line

In the next patch we'll need to clear the header lists if the user
specifies --no-add-headers or --no-to or --no-cc. This actually cuts

git status: Show detailed dirty status of submodules in long format
Since 1.7.0 there are three reasons a submodule is considered modified
against the work tree: It contains new commits, modified content or
untracked content. Lets show all reasons in the long format of git status,
so the user can better asses the nature of the modification. This change
does not affect the short and porcelain formats.
Two new members are added to "struct wt_status_change_data" to store the
information gathered by run_diff_files(). wt-status.c uses the new flag
DIFF_OPT_DIRTY_SUBMODULES to tell diff-lib.c it wants to get detailed
dirty information about submodules.
A hint line for submodules is printed in the dirty header when dirty
submodules are present.

grep: Colorize filename, line number, and separator
Colorize the filename, line number, and separator in git grep output, as
GNU grep does. The colors are customizable through color.grep.<slot>.
The default is to only color the separator (in cyan), since this gives
the biggest legibility increase without overwhelming the user with
colors. GNU grep also defaults cyan for the separator, but defaults to
magenta for the filename and to green for the line number, as well.
There is one difference from GNU grep: When a binary file matches
without -a, GNU grep does not color the <file> in "Binary file <file>
matches", but we do.
Like GNU grep, if --null is given, the null separators are not colored.
For config.txt, use a a sub-list to describe the slots, rather than
a single paragraph with parentheses, since this is much more readable.
Remove the cast to int for `rm_eo - rm_so` since it is not necessary.

Maybe this option could be made the default in the long run, with
another --no-ff option to disable this default behavior, but that

t3417: Add test cases for "rebase --whitespace=fix"
The command "git rebase --whitespace=fix HEAD~<N>" is supposed to
only clean up trailing whitespace, and the expectation is that it
cannot fail.
Unfortunately, if one commit adds a blank line at the end of a file
and a subsequent commit adds more non-blank lines after the blank
line, "git apply" (used indirectly by "git rebase") will fail to apply
the patch of the second commit.

apply: Allow blank context lines to match beyond EOF
"git apply --whitespace=fix" will not always succeed when used
on a series of patches in the following circumstances:
* One patch adds a blank line at the end of a file. (Since
--whitespace=fix is used, the blank line will *not* be added.)
* The next patch adds non-blank lines after the blank line
introduced in the first patch. That patch will not apply
because the blank line that is expected to be found at end
of the file is no longer there.
A patch series that starts by deleting lines at the end
will fail in a similar way.
Fix this problem by allowing a blank context line at the beginning
of a hunk to match if parts of it falls beyond end of the file.
We still require that at least one non-blank context line match
before the end of the file.
If the --ignore-space-change option is given (as well as the
--whitespace=fix option), blank context lines falling beyond the end
of the file will be copied unchanged to the target file (i.e. they
will have the same line terminators and extra spaces will not be
removed).
Signed-off-by: Björn Gustavsson <bgustavsson@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
In the next commit, we will make it possible for blank context
lines to match beyond the end of the file. That means that a hunk
with a preimage that has more lines than present in the file may
be possible to successfully apply. Therefore, we must remove
the quick rejection test in find_pos().
find_pos() will already work correctly without the quick
rejection test, but that might not be obvious. Therefore,
comment the test for handling out-of-range line numbers in
find_pos() and cast the "line" variable to the same (unsigned)
type as img->nr.
What are performance implications of removing the quick
rejection test?
It can only help "git apply" to reject a patch faster. For example,
if I have a file with one million lines and a patch that removes
slightly more than 50 percent of the lines and try to apply that
patch twice, the second attempt will fail slightly faster
with the test than without (based on actual measurements).
However, there is the pathological case of a patch with many
more context lines than the default three, and applying that patch
using "git apply -C1". Without the rejection test, the running
time will be roughly proportional to the number of context lines
times the size of the file. That could be handled by writing
a more complicated rejection test (it would have to count the
number of blanks at the end of the preimage), but I don't find
that worth doing until there is a real-world use case that
would benfit from it.
It would be possible to keep the quick rejection test if
--whitespace=fix is not given, but I don't like that from
a testing point of view.

reset: disallow using --keep when there are unmerged entries
The use case for --keep option is to remove previous commits unrelated
to the current changes in the working tree. So in this use case we are
not supposed to have unmerged entries. This is why it seems safer to
just disallow using --keep when there are unmerged entries.
And this patch changes the error message when --keep was disallowed and
there were some unmerged entries from:
error: Entry 'file1' would be overwritten by merge. Cannot merge.
fatal: Could not reset index file to revision 'HEAD^'.
to:
fatal: Cannot do a keep reset in the middle of a merge.
which is nicer.

These tests have been broken since they were introduced in commits ca2cedb (git-submodule: add support for --rebase., 2009-04-24) and 42b4917 (git-submodule: add support for --merge., 2009-06-03).
'git submodule init' expects the submodules to exist in the index.
In this case, the submodules don't exist and therefore looking for
the submodules will always fail. To make matters worse, git submodule
fails visibly to the user by saying:
error: pathspec 'rebasing' did not match any file(s) known to git.
Did you forget to 'git add'?
but doesn't return an error code. This allows the test to fail silently.
Fix it by adding the submodules first.

Revert "git-svn: always initialize with core.autocrlf=false"
git-svn rebase used to have issues with CRLF conversion. Since these issues
have been fixed, we can safely revert the work-around that disables CRLF
conversion.
Before commit d3c9634e, performing a "git svn rebase" that fetched a
change containing CRLFs corrupted the git-svn meta-data. This was
worked around in d3c9634e by setting core.autocrlf to "false" in the
per-repo config when initing the clone. However, if the config
variable was later changed, the corruption would still occur.
This patch tries to fix it while allowing core.autocrlf to be
enabled, by disabling filters when when hashing.
git-svn is currently the only call-site for hash_and_insert_object
(apart from the test-suite), so changing it should be safe.
