3f1451326a Adjust stat width calculations to take --graph output into account
The recent change to compute the width of diff --stat did not take into
consideration the output from --graph. The consequence is that when both
options are used, e.g. in 'log --stat --graph', the lines are too long.

Adjust stat width calculations to take --graph output into account.

17c82211ec Be more specific if upstream branch is not tracked
If the branch configured as upstream didn't have a local tracking
branch, git said "Upstream branch not found". We can be more helpful,
and separate the cases when upstream is not configured, and when it is
configured, but the upstream branch is not tracked in a local branch.

The following configuration leads to the second scenario:

    [remote "origin"]
    	    url = ...
            fetch = refs/heads/master
    [branch "master"]
            remote = origin
            merge = refs/heads/master

'git pull' will work on master, but master@{upstream} is not defined.

9884e67f9d Provide branch name in error message when using @{u}
When using @{u} or @{upstream} it is common to omit the branch name,
implying current branch. If the upstream is not configured, the error
message was "No upstream branch found for ''".

When resolving '@{u}', branch_get() is called, which almost always
returns a description of a branch. This allows us to use a branch name
in the error message, even if the user said something like '@{u}'.

The only case when branch_get() returns NULL is when HEAD points to so
something which is not a branch. Of course this also means that no
upstream is configured, but it is better to directly say that HEAD
does not point to a branch.

1b4aee94aa t1507: add tests to document @{upstream} behaviour
In preparation for future changes, add tests which show error messages
with @{upstream} in various conditions:

- test branch@{u} with . as remote
- check error message for branch@{u} on a branch with
  * no upstream,
  * on a branch with a configured upstream which doesn't have a
    remote-tracking branch
- check error message for branch@{u} when branch 'branch' does not
  exist
- check error message for @{u} without the branch name

Right now the messages are very similar, but various cases can and
will be distinguished.

Note: test_i18ncmp is not used, because currently error output is not
internationalized. test_cmp will be switched to test_i18ncmp in a later
patch, when error messages are internationalized.

6d5b93f29f cherry-pick: do not expect file arguments
If a commit-ish passed to cherry-pick or revert happens to have a file
of the same name, git complains that the argument is ambiguous and
advises to use '--'. To make things worse, the '--' argument is removed
by parse_options, und so passing '--' has no effect.

Instead, always interpret cherry-pick/revert arguments as revisions.

2565b43bd2 properly keep track of current working directory
Various failure modes in the repository detection code path currently
quote the wrong directory in their error message. The working directory
is changed iteratively to the parent directory until a git repository is
found. If the working directory cannot be changed to the parent
directory for some reason, the detection gives up and prints an error
message. The error message should report the current working directory.

Instead of continually updating the 'cwd' variable, which is actually
used to remember the original working directory, the 'offset' variable
is used to keep track of the current working directory. At the point
where the affected error handling code is called, 'offset' already
points to the end of the parent of the working directory, rather than
the current working directory.

Fix this by explicitly using a variable 'offset_parent' and update
'offset' concurrently with the call to chdir.

In a similar fashion, the function get_device_or_die() would print the
original working directory in case of a failure, rather than the current
working directory. Fix this as well by making use of the 'offset'
variable.

Lastly, replace the phrase 'mount parent' with 'mount point'. The former
appears to be a typo.

d57e490af3 fast-import doc: cat-blob and ls responses need to be consumed quickly
If fast-import's command pipe and the frontend's cat-blob/ls response
pipe are both filled, there can be a deadlock.  Luckily all existing
frontends consume any pending cat-blob/ls responses completely before
writing the next command.

Document the requirements so future frontend authors and users can be
spared from the problem, too.  It is not always easy to catch that
kind of bug by testing.

To set the scene, add some words of explanation to help the novice
understand that "cat-blob" and "ls" output are meant for consumption
by the frontend.

a6801adc52 submodules: recursive fetch also checks new tags for submodule commits
Since 88a21979c (fetch/pull: recurse into submodules when necessary) all
fetched commits are examined if they contain submodule changes (unless
configuration or command line options inhibit that). If a newly recorded
submodule commit is not present in the submodule, a fetch is run inside
it to download that commit.

Checking new refs was done in an else branch where it wasn't executed for
tags. This normally isn't a problem because tags are only fetched with
the branches they live on, then checking the new commits in the fetched
branches for submodule commits will also process all tags. But when a
specific tag is fetched (or the refspec contains refs/tags/) commits only
reachable by tags won't be searched for submodule commits, which is a bug.

Fix that by moving the code outside the if/else construct to handle new
tags just like any other ref. The performance impact of adding tags that
most of the time lie on a branch which is checked anyway for new submodule
commit should be minimal, as since 6859de4 (fetch: avoid quadratic loop
checking for updated submodules) all ref-tips are collected first and then
fed to a single rev-list.

6f4c347ca1 http: use newer curl options for setting credentials
We give the username and password to curl by sticking them
in a buffer of the form "user:pass" and handing the result
to CURLOPT_USERPWD. Since curl 7.19.1, there is a split
mechanism, where you can specify each element individually.

This has the advantage that a username can contain a ":"
character. It also is less code for us, since we can hand
our strings over to curl directly. And since curl 7.17.0 and
higher promise to copy the strings for us, we we don't even
have to worry about memory ownership issues.

Unfortunately, we have to keep the ugly code for old curl
around, but as it is now nicely #if'd out, we can easily get
rid of it when we decide that 7.19.1 is "old enough".

aa0834a04e http: clean up leak in init_curl_http_auth
When we have a credential to give to curl, we must copy it
into a "user:pass" buffer and then hand the buffer to curl.
Old versions of curl did not copy the buffer, and we were
expected to keep it valid. Newer versions of curl will copy
the buffer.

Our solution was to use a strbuf and detach it, giving
ownership of the resulting buffer to curl. However, this
meant that we were leaking the buffer on newer versions of
curl, since curl was just copying it and throwing away the
string we passed. Furthermore, when we replaced a
credential (e.g., because our original one was rejected), we
were also leaking on both old and new versions of curl.

This got even worse in the last patch, which started
replacing the credential (and thus leaking) on every http
request.

Instead, let's use a static buffer to make the ownership
more clear and less leaky.  We already keep a static "struct
credential", so we are only handling a single credential at
a time, anyway.

51ef7a6e80 gitweb: Refinement highlightning in combined diffs
The highlightning of combined diffs is currently disabled.  This is
because output from a combined diff is much harder to highlight because
it is not obvious which removed and added lines should be compared.

Current code requires that the number of added lines is equal to the
number of removed lines and only skips first +/- character, treating
second +/- as a line content, Thus, it is not possible to simply use
existing algorithm unchanged for combined diffs.

Let's start with a simple case: only highlight changes that come from
one parent, i.e. when every removed line has a corresponding added line
for the same parent.  This way the highlightning cannot get wrong. For
example, following diffs would be highlighted:

	- removed line for first parent
	+ added line for first parent
	  context line
	 -removed line for second parent
	 +added line for second parent

or

	- removed line for first parent
	 -removed line for second parent
	+ added line for first parent
	 +added line for second parent

but following output will not:

	- removed line for first parent
	 -removed line for second parent
	 +added line for second parent
	++added line for both parents

In other words, we require that pattern of '-'-es in pre-image matches
pattern of '+'-es in post-image.

Further changes may introduce more intelligent approach that better
handles combined diffs.

5fb6ddf67a gitweb: Highlight interesting parts of diff
Reading diff output is sometimes very hard, even if it's colored,
especially if lines differ only in few characters.  This is often true
when a commit fixes a typo or renames some variables or functions.

This commit teaches gitweb to highlight characters that are different
between old and new line with a light green/red background.  This should
work in the similar manner as in Trac or GitHub.

The algorithm that compares lines is based on contrib/diff-highlight.
Basically, it works by determining common prefix/suffix of corresponding
lines and highlightning only the middle part of lines.  For more
information, see contrib/diff-highlight/README.

Combined diffs are not supported but a following commit will change it.

Since we need to pass esc_html()'ed or esc_html_hl_regions()'ed lines to
format_diff_lines(), so it was taught to accept preformatted lines
passed as a reference.

f4a8102650 gitweb: Push formatting diff lines to print_diff_chunk()
Now lines are formatted closer to place where we actually use HTML
formatted output.

This means that we put raw lines in the @chunk accumulator, rather than
formatted lines.  Because we still need to know class (type) of line
when accumulating data to post-process and print, process_diff_line()
subroutine was retired and replaced by diff_line_class() used in
git_patchset_body() and new restructured format_diff_line() used in
print_diff_chunk().

As a side effect, we have to pass \%from and \%to down to callstack.

This is a preparation patch for diff refinement highlightning. It's not
meant to change gitweb output.

If print_diff_chunk() was left as is, the new function
print_inline_diff_lines() could reorder diff lines.  It first prints all
context lines, then all removed lines and finally all added lines.  If
the diff output consisted of mixed added and removed lines, gitweb would
reorder these lines.  This is true for combined diff output, for
example:

	 - removed line for first parent
	 + added line for first parent
	  -removed line for second parent
	 ++added line for both parents

would be rendered as:

	- removed line for first parent
	 -removed line for second parent
	+ added line for first parent
	++added line for both parents

To prevent gitweb from reordering lines, print_diff_chunk() calls
print_diff_lines() as soon as it detects that both added and removed
lines are present and there was a class change, and at the end of chunk.

d21102c9ff gitweb: Extract print_sidebyside_diff_lines()
Currently, print_sidebyside_diff_chunk() does two things: it
accumulates diff lines and prints them.  Accumulation may be used to
perform additional operations on diff lines, so it makes sense to split
these two things.  Thus, whole code that formats and prints diff lines
in the 'side-by-side' manner is moved out of print_sidebyside_diff_chunk()
to a separate subroutine and two conditions that control printing
diff liens are merged.

Thanks to that, we can easily (in later patches) replace call to that
subroutine with a call to more generic print_diff_lines() that will
control whether 'inline' or 'side-by-side' diff should be printed.

As a side effect, context lines are printed just before printing added
and removed lines, and at the end of chunk (previously, they were
printed immediately on the class change).  However, this doesn't change
gitweb output.

The outcome of this patch is that print_sidebyside_diff_chunk() is now
much shorter and easier to read.

While at it, drop the '# assume that it is change' comment.  According
to Jakub Narębski:

	What I meant here when I was writing it that they are lines that
	changed between two versions, like '!' in original (not unified)
	context format.

	We can omit this comment.

9768a9d884 gitweb: Pass esc_html_hl_regions() options to esc_html()
With this change, esc_html_hl_regions() accepts options and passes them
down to esc_html().  This may be needed if a caller wants to pass
-nbsp=>1 to esc_html().

The idea and implementation example of this change was described in
337da8d2 (gitweb: Introduce esc_html_match_hl and esc_html_hl_regions,
2012-02-27).  While other suggestions may be more useful in some cases,
there is no need to implement them at the moment.  The
esc_html_hl_regions() interface may be changed later if it's needed.

cbbea3dfc1 gitweb: esc_html_hl_regions(): Don't create empty <span> elements
If $end is equal to or less than $begin, esc_html_hl_regions()
generates an empty <span> element.  It normally shouldn't be visible in
the web browser, but it doesn't look good when looking at page source.
It also minimally increases generated page size for no special reason.

ce61fb968f gitweb: Use descriptive names in esc_html_hl_regions()
The $s->[0] and $s->[1] variables look a bit cryptic.  Let's rename them
to $begin and $end so that it's clear what they do.

df478b744c git-cherry-pick: add allow-empty option
git cherry-pick fails when picking a non-ff commit that is empty.  The advice
given with the failure is that a git-commit --allow-empty should be issued to
explicitly add the empty commit during the cherry pick.  This option allows a
user to specify before hand that they want to keep the empty commit.  This
eliminates the need to issue both a cherry pick and a commit operation.

059a500d25 blame: accept --need-minimal
Between v1.7.1 and v1.7.2, 582aa00bdf switched the default "diff"
invocation not to use XDF_NEED_MINIMAL, but this breaks "git blame"
rather badly.

Allow the command line option to ask for an extra careful matching.

36e6c803a1 Kick off post 1.7.10 cycle
I tentatively named the release notes "1.7.11" but this may have to
be renamed to "1.8" or some other name later.  Let's see how well
we would do during this cycle.
