t/t91XX-svn: start removing use of "git-" from these tests
Subversion tests use too many "git-foo" form, so I am converting them
in two steps.
This first step replaces literal strings "remotes/git-svn" and "git-svn-id"
by introducing $remotes_git_svn and $git_svn_id constants defined as shell
variables. This will reduce the number of false hits from "git grep".

git-svn: fix handling of even funkier branch names
Apparently do_switch() tolerates the lack of escaping in less
funky branch names. For the really strange and scary ones, we
need to escape them properly. It strangely maintains compatible
with the existing handling of branch names with spaces and
exclamation marks.

The previous tests all expected the results from SVN and Git to be
identical, and expected both to return success. This cannot be
guaranteed: SVN changed the message style between 1.4 and 1.5, and
in 1.5, sets a failure exit code.
Change the tests to verify that 'git svn info <item>' sets a failure
exit code, and that its output contains the file name. This should
hopefully catch all other errors.

Not checking the error code of a function used to transform and
send data makes me nervous. It currently returns "undef" on
success; so die if we get any result other than "undef" because
it's likely something went wrong somewhere. I really wish this
function returned an MD5 like send_stream (or better yet, SHA1)
for verification.
Mention the fact that 'git annotate' is only for backward compatibility.
When somebody is reading git-blame.txt (or git-annotate.txt) for the first
time, the message we would like to send is:
(1) Here is why you would want to use this command, what it can do
(perhaps more than what you would have expected from "$scm blame"),
and how you tell it to do what it does.
This is obvious.
(2) You might have heard of the command with the other name. There is no
difference between the two, except they differ in their default
output formats.
This is essential to answer: "git has both? how are they different?"
(3) We tend to encourage blame over annotate for new scripts and new
people, but there is no reason to choose one over the other.
This is not as important as (2), but would be useful to avoid
repeated questions about "when will we start deprecating this?"
As long as we describe (2) on git-annotate page clearly enough, people who
read git-blame page first and get curious can refer to git-annotate page.
While at it, subtly hint (3) without being overly explicit.
There is no reason to have a separate variable cmd_is_annotate;
OUTPUT_ANNOTATE_COMPAT option is supposed to produce the compatibility
output, and we should produce the same output even when the command was
not invoked as "annotate" but as "blame -c".
* jc/maint-log-grep:
log --author/--committer: really match only with name part
diff --cumulative is a sub-option of --dirstat
bash completion: Hide more plumbing commands
log --author/--committer: really match only with name part
When we tried to find commits done by AUTHOR, the first implementation
tried to pattern match a line with "^author .*AUTHOR", which later was
enhanced to strip leading caret and look for "^author AUTHOR" when the
search pattern was anchored at the left end (i.e. --author="^AUTHOR").
This had a few problems:
* When looking for fixed strings (e.g. "git log -F --author=x --grep=y"),
the regexp internally used "^author .*x" would never match anything;
* To match at the end (e.g. "git log --author='google.com>$'"), the
generated regexp has to also match the trailing timestamp part the
commit header lines have. Also, in order to determine if the '$' at
the end means "match at the end of the line" or just a literal dollar
sign (probably backslash-quoted), we would need to parse the regexp
ourselves.
An earlier alternative tried to make sure that a line matches "^author "
(to limit by field name) and the user supplied pattern at the same time.
While it solved the -F problem by introducing a special override for
matching the "^author ", it did not solve the trailing timestamp nor tail
match problem. It also would have matched every commit if --author=author
was asked for, not because the author's email part had this string, but
because every commit header line that talks about the author begins with
that field name, regardleses of who wrote it.
Instead of piling more hacks on top of hacks, this rethinks the grep
machinery that is used to look for strings in the commit header, and makes
sure that (1) field name matches literally at the beginning of the line,
followed by a SP, and (2) the user supplied pattern is matched against the
remainder of the line, excluding the trailing timestamp data.
git-gui: Fix diff parsing for lines starting with "--" or "++"
Languages like Lua and SQL use "--" to mark a line as commented out.
If this appears at column 0 and is part of the pre-image we may see
"--- foo" in the diff, indicating that the line whose content is
"-- foo" has been removed from the new version.
git-gui was incorrectly parsing "--- foo" as the old file name
in the file header, causing it to generate a bad patch file when
the user tried to stage or unstage a hunk or the selected line.
We need to keep track of where we are in the parsing so that we do
not misread a deletion or addition record as part of the header.

git-gui: Make F5 reselect a diff, if an untracked file is selected.
If an untracked file is selected, F5 and other manual rescan synonyms

file clicked is untracked itself.
The objective is to make it easier to ignore untracked files showing

- Rescan auto-selects the first conflicting file, or if none
a modified tracked file, if nothing was selected previously.
- Resolving a conflict auto-selects the nearest conflicting
file, or nothing if everything is resolved.
- Staging the last remaining hunk auto-selects the nearest
modified staged file.

files, because git-gui did not provide any tools to resolve
them from within the GUI. But now that we have added mergetool
capabilities, it is more likely to cause accidental and

Currently the code looks for line break characters in order to prepend
"remote: " to every line received as many lines can be sent in a single
chunk. However the opposite might happen too, i.e. a single message
line split amongst multiple chunks. This patch adds support for the
later case to avoid displays like:
Previous HEAD position was 1234abcd... commit subject line
when leaving a detached HEAD for another commit. Ths C
version attempted to implement this, but got the condition
wrong such that the behavior never triggered.
This patch simplifies the conditions for showing the message
to the ones used by the shell version: any time we are
leaving a detached HEAD and the new and old commits are not
the same (this suppresses it for the "git checkout -b new"
case recommended when you enter the detached state).

This patch turns ref markers for tags and heads into links to
appropriate views for the ref name, depending on current context.
For annotated tags, we link to the tag view, unless that's the current
view, in which case we switch to shortlog. For other refs, we prefer the
current view if it's history or (short)log, and default to shortlog
otherwise.
Appropriate changes are made in the CSS to prevent ref markers from
being annoyingly blue and underlined, unless hovered. A visual
indication of the target view difference is also implemented by making
annotated tags show up in italic.

Bring local clone's origin URL in line with that of a remote clone
On a local clone, "git clone" would use the fully DWIMmed path as the origin
URL in the resulting repo. This was slightly inconsistent with the case of a
remote clone where the _given_ URL was used as the origin URL (because the
DWIMming was done remotely, and was therefore not available to "git clone").
This behaviour caused problems when cloning a local non-bare repo with
relative submodule URLs, because these submodule URLs would then be resolved
against the DWIMmed URL (e.g. "/repo/.git") instead of the given URL (e.g.
"/repo").
This patch teaches "git clone" to use the _given_ URL - instead of the
DWIMmed path - as the origin URL. This causes relative submodule URLs to be
resolved correctly, as long the _given_ URL indicates the correct directory
against which the submodule URLs should be resolved.
The patch also updates a testcase that contained the old-style origin URLs.

git commit --author=$name: look $name up in existing commits
This allows "git commit --author=$name" to accept a name that is not in
the required "A U Thor <author@example.xz>" format, and use that to look
up an author name that matches from existing commits.
When using this feature, it is the user's responsibility to give a name
that uniquely matches the name s/he wants, as the logic returns the name
from the first matching commit.
When the tracked contents have CRLF line endings, colored diff output
shows "^M" at the end of output lines, which is distracting, even though
the pager we use by default ("less") knows to hide them.
The problem is that "less" hides a carriage-return only at the end of the
line, immediately before a line feed. The colored diff output does not
take this into account, and emits four element sequence for each line:
- force this color;
- the line up to but not including the terminating line feed;
- reset color
- line feed.
By including the carriage return at the end of the line in the second
item, we are breaking the smart our pager has in order not to show "^M".
This can be fixed by changing the sequence to:
- force this color;
- the line up to but not including the terminating end-of-line;
- reset color
- end-of-line.
where end-of-line is either a single linefeed or a CRLF pair. When the
output is not colored, "force this color" and "reset color" sequences are
both empty, so we won't have this problem with or without this patch.

The description of crlf attribute incorrectly said that "-crlf" means

that is not the same thing.
We also have supported attribute macros and via that mechanism a handy

This is a tricky piece of code.
We still incorrectly enforce "match_beginning" for -U0 matches.

$ echo a >victim
$ git add victim
$ echo b >>victim
$ git diff -U0 >patch

The change inserts a new line before the second line, but we insist it to
be applied at the beginning. As the result, the code refuses to apply it
at the original offset, and we end up adding the line at the beginning.
Updates to the test script are by Clemens Buchacher.
