b972ea59e4 git-gui: Always use -v option to push.
Right now `git-push -v` is actually not that verbose; it merely adds
the URL it is pushing to.  This can be informative if you are pushing
to a configured remote, as you may not actually remember what URL that
remote is connected to.  That detail can be important if the push
fails and you attempt to communicate the errors to a 3rd party to help
you resolve the issue.

86a2af6087 git-gui: Remove no longer used pull from remote code.
Because we aren't going to support single click pulling of changes from
an existing remote anytime in the near future, I'm moving the code which
used to perform that action.  Hopefully we'll be able to do something
like it in the near-future, but also support local branches just as
easily.

1d6a978752 git-gui: Added arbitrary branch pushing support.
Because its common for some users to push topic branches to a remote
repository for review and merging by other parties, users need an
easy way to push one or more branches to a remote repository without
needing to edit their .git/config file anytime their set of active
branches changes.

We now provide a basic 'Push...' menu action in the Push menu which
opens a dialog allowing the user to select from their set of local
branches (refs/heads, minus tracking branches).  The user can designate
which repository to send the changes to by selecting from an already
configured remote or by entering any valid Git URL.

156b29211a git-gui: Always use lsearch -exact, to prevent globbing.
Anytime we are using lsearch we are doing [lsearch -sorted] and we
are applying it to file paths (or file path like things).  Its valid
for these to contain special glob characters, but when that happens
we do not want globbing to occur.  Instead we really need exact
match semantics.  Always supplying -exact to lsearch will ensure that
is the case.

5f8b70b1dc git-gui: Maintain the same file list for diff during refresh.
I just noticed that a file was always jumping to compare against HEAD
and the index during a refresh, even if the diff viewer was comparing
the index against the working directory prior to the refresh.  The
bug turned out to be caused by a foreach loop going through all file
list names searching for the path.  Since $ui_index was the first one
searched and the file was contained in that file list the loop broke
out, leaving $w set to $ui_index when it had been set by the caller
to $ui_workdir.  Silly bug caused by using a parameter as a loop
index.

e1b161161d diffcore-pickaxe: fix infinite loop on zero-length needle
The "contains" algorithm runs into an infinite loop if the needle string
has zero length. The loop could be modified to handle this, but it makes
more sense to simply have an empty needle return no matches. Thus, a
command like
  git log -S
produces no output.

We place the check at the top of the function so that we get the same
results with or without --pickaxe-regex. Note that until now,
  git log -S --pickaxe-regex
would match everything, not nothing.

Arguably, an empty pickaxe string should simply produce an error
message; however, this is still a useful assertion to add to the
algorithm at this layer of the code.

cb280e1075 Allow non-developer to clone, checkout and fetch more easily.
The code that uses committer_info() in reflog can barf and die
whenever it is asked to update a ref.  And I do not think
calling ignore_missing_committer_name() upfront like recent
receive-pack did in the aplication is a reasonable workaround.

What the patch does.

 - git_committer_info() takes one parameter.  It used to be "if
   this is true, then die() if the name is not available due to
   bad GECOS, otherwise issue a warning once but leave the name
   empty".  The reason was because we wanted to prevent bad
   commits from being made by git-commit-tree (and its
   callers).  The value 0 is only used by "git var -l".

   Now it takes -1, 0 or 1.  When set to -1, it does not
   complain but uses the pw->pw_name when name is not
   available.  Existing 0 and 1 values mean the same thing as
   they used to mean before.  0 means issue warnings and leave
   it empty, 1 means barf and die.

 - ignore_missing_committer_name() and its existing caller
   (receive-pack, to set the reflog) have been removed.

 - git-format-patch, to come up with the phoney message ID when
   asked to thread, now passes -1 to git_committer_info().  This
   codepath uses only the e-mail part, ignoring the name.  It
   used to barf and die.  The other call in the same program
   when asked to add signed-off-by line based on committer
   identity still passes 1 to make sure it barfs instead of
   adding a bogus s-o-b line.

 - log_ref_write in refs.c, to come up with the name to record
   who initiated the ref update in the reflog, passes -1.  It
   used to barf and die.

The last change means that git-update-ref, git-branch, and
commit walker backends can now be used in a repository with
reflog by somebody who does not have the user identity required
to make a commit.  They all used to barf and die.

I've run tests and all of them seem to pass, and also tried "git
clone" as a user whose GECOS is empty -- git clone works again
now (it was broken when reflog was enabled by default).

But this definitely needs extra sets of eyeballs.

3f7fd924a9 git-gui: Remove Pull menu and cleanup Branch/Fetch/Push menus.
The Pull menu as it stands right now is a really horrible idea.  Most
users will have too many branches show up in this menu, and what with
the new globbing syntax for fetch entries we were offering up possible
merging that just isn't really valid.  So this menu is dead and will
be rewritten to support better merge capabilities.

The Branch menu shouldn't include a separator entry if there are no
branches, it just looks too damn weird.  This can happen in an initial
repository before any branches have been created and before the first
commit.

The Fetch and Push menus should just be organized around their own
menus rather than being given the menu to populate.

23effa79f7 git-gui: Force focus to the diff viewer on mouse click.
Apparently a "feature" of Tcl/Tk on Mac OS X is that a disabled text
widget cannot receive focus or receive a selection within it.  This
makes the diff viewer almost useless on that platform as you cannot
select individual parts of the buffer.

Now we force focus into the diff viewer when its clicked on with

work within the viewer just like it does on other less sane systems,

4e55d19a13 git-gui: Cleanup end-of-line whitespace in commit messages.
When committing changes its useless to have trailing whitespace on the
end of a line within the commit message itself; this serves no purpose
beyond wasting space in the repository.  But it happens a lot on my
Mac OS X system if I copy text out of a Terminal.app window and paste
it into git-gui.

We now clip any trailing whitespace from the commit buffer when loading
it from a file, when saving it out to our backup file, or when making
the actual commit object.

I also fixed a bug where we lost the commit message buffer if you quit
without editing the text region.  This can happen if you quit and restart
git-gui frequently in the middle of an editing session.

535514f1f3 New files in git weren't being downloaded during CVS update
If a repository was checked out via git-cvsserver and then later a new
file is added to the git repository via some other method; a CVS update
wasn't fetching the new file.

It would be reported as a new file as
 A some/dir/newfile.c
but would never appear in the directory.

The problem seems to be that git-cvsserver was treating these two cases
identically, as "A" type results.

1. New file in repository
2. New file locally

In fact, traditionally, case 1 is treated as a "U" result, and case 2
only is treated as an "A" result.  "A", should just report that the file
is added locally and then skip that file during an update as there is
(of course) nothing to send.

In both these cases there is no working revision, so the checking for
"is there no working revision" will return true.  The test for case 2
needs refining to say "if there is no working revision and no upstream
revision".  This patch does just that, leaving case 1 to be handled by
the normal "U" handler.

I've also updated the log message to more accurately describe the
operation.  i.e. that "A" means that content is scheduled for addition;
not that it actually has been added.

30b14ed390 git-gui: Elide CRs appearing in diff output from display.
If we are displaying a diff for a DOS-style (CRLF) formatted file then
the Tk text widget would normally show the CR at the end of every line;
in most fonts this will come out as a square box.  Rather than showing
this character we'll tag it with a tag which forces the character to
be elided away, so its not displayed.  However since the character is
still within the text buffer we can still obtain it and supply it over
to `git apply` when staging or unstaging an individual hunk, ensuring
that the file contents is always fully preserved as-is.

a25c518933 git-gui: Allow staging/unstaging individual diff hunks.
Just like `git-add --interactive` we can now stage and unstage individual
hunks within a file, rather than the entire file at once.  This works
on the basic idea of scanning backwards from the mouse position to
find the hunk header, then going forwards to find the end of the hunk.
Everything in that is sent to `git apply --cached`, prefixed by the
diff header lines.

We ignore whitespace errors while applying a hunk, as we expect the
user's pre-commit hook to catch any possible problems. This matches
our existing behavior with regards to adding an entire file with
no whitespace error checking.

Applying hunks means that we now have to capture and save the diff header
lines, rather than chucking them.  Not really a big deal, we just needed
a new global to hang onto that current header information.  We probably
could have recreated it on demand during apply_hunk but that would mean
we need to implement all of the funny rules about how to encode weird
path names (e.g. ones containing LF) into a diff header so that the
`git apply` process would understand what we are asking it to do.  Much
simpler to just store this small amount of data in a global and replay
it when needed.

I'm making absolutely no attempt to correct the line numbers on the
remaining hunk headers after one hunk has been applied.  This may
cause some hunks to fail, as the position information would not be
correct.  Users can always refresh the current diff before applying a
failing hunk to work around the issue.  Perhaps if we ever implement
hunk splitting we could also fix the remaining hunk headers.

Applying hunks directly means that we need to process the diff data in
binary, rather than using the system encoding and an automatic linefeed
translation.  This ensures that CRLF formatted files will be able to be
fed directly to `git apply` without failures.  Unfortunately it also means
we will see CRs show up in the GUI as ugly little boxes at the end of
each line in a CRLF file.

0fd49d0a7d git-gui: Display database stats (count-objects -v) on demand.
Its nice to know how many loose objects and roughly how much disk space
they are taking up, so that you can guestimate about when might be a
good time to run 'Compress Database'.  The same is true of packfiles,
especially once the automatic keep-pack code in git-fetch starts to
be more widely used.

We now offer the output of count-objects -v in a nice little dialog
hung off the Repository menu.  Our labels are slightly more verbose
than those of `count-objects -v`, so users will hopefully be able
to make better sense of what we are showing them here.

We probably should also offer pack file size information, and data
about *.idx files which exist which lack corresponding *.pack files
(a situation caused by the HTTP fetch client).  But in the latter
case we should only offer the data once we have way to let the user
clean up old and inactive index files.

59885273c3 git-gui: Handle commit encoding better.
Git prefers that all log messages are encoding in UTF-8.  So now when
git-gui generates the commit message it converts the commit message
text from the internal Tcl Unicode representation into a UTF-8 file.
The file is then fed as stdin to git-commit-tree.  I had to start
using a file here rather than feeding the message in with << as
<< uses the system encoding, which we may not want.

When we reload a commit message via git-cat-file we are getting the
raw byte stream, with no encoding performed by Git itself.  So unless
the new 'encoding' header appears in the message we should probably
assume it is utf-8 encoded; but if the header is present we need to
use whatever it claims.

51a989ba5a git-gui: Honor system encoding for filenames.
Since git operates on filenames using the operating system encoding
any data we are receiving from it by way of a pipe, or sending to it
by way of a pipe must be formatted in that encoding.  This should
be the same as the Tcl system encoding, as its the encoding that
applications should be using to converse with the operating system.

Sadly this does not fix the gitweb/test file in git.git on Macs;
that's due to something really broken happening in the filesystem.

0565246a7c git-gui: Remove spurious newline in untracked file display.
This newline is stupid; it doesn't get put here unless the file
is very large, and then its just sort of out of place.

d3596fd948 git-gui: When possible show the type of an untracked file.
Users may want to know what a file is before they add it to the
repository, especially if its a binary file.  So when possible
invoke 'file' on the path and try to get its output.  Since
this is strictly advice to the user we won't bother to report
any failures from our attempt to run `file`.

Since some file commands also output the path name they were
given we look for that case and strip it off the front of the
returned output before placing it into the diff viewer.

19b41e4559 git-gui: Limit display of large untracked files.
Our internal diff viewer displays untracked files to help users see if
they should become tracked, or not.  It is not meant as a full file
viewer that handles any sort of input.  Consequently it is rather
unreasonable for users to expect us to show them very large files.
Some users may click on a very big file (and not know its very big)
then get surprised when Tk takes a long time to load the content and
render it, especially if their memory is tight and their OS starts to
swap processes out.

Instead we now limit the amount of data we load to the first 128 KiB
of any untracked file.  If the file is larger than 128 KiB we display
a warning message at the top of our diff viewer to notify the user
that we are not going to load the entire thing.  Users should be able
to recognize a file just by its first 128 KiB and determine if it
should be added to the repository or not.

Since we are loading 128 KiB we may as well scan it to see if the
file is binary.  So I've removed the "first 8000 bytes" rule and
just allowed git-gui to scan the entire data chunk that it read in.
This is probably faster anyway if Tcl's [string range] command winds
up making a copy of the data.

464c9ffee4 git-gui: Don't show content of untracked binary files.
A binary file can be very large, and showing the complete content of
one is horribly ugly and confusing.  So we now use the same rule that
core Git uses; if there is a NUL byte (\0) within the first 8000 bytes
of the file we assume it is binary and refuse to show the content.

Given that we have loaded the entire content of the file into memory
we probably could just afford to search the whole thing, but we also
probably should not load multi-megabyte binary files either.

124355d32c git-gui: Always start a rescan on an empty diff.
If we got an empty diff its probably because the modification time of
the file was changed but the file content hasn't been changed.  Typically
this happens because an outside program modified the file and git-gui
was told to not run 'update-index --refresh', as the user generally
trusts file modification timestamps.  But we can also get an empty diff
when a program undos a file change and still updates the modification
timestamp upon saving, but has undone the file back to the same as what
is in the index or in PARENT.

So even if gui.trustmtime is false we should still run a rescan on
an empty diff.  This change also lets us cleanup the dialog message
that we show when this case occurs, as its no longer got anything to
do with Trust File Modification Timestamps.

e54a1bd122 git-gui: Ignore 'No newline at end of file' marker line.
If one or both versions of the file don't have a newline at the end
of the file we get a line telling us so in the diff output.  This
shouldn't be tagged, nor should it generate a warning about not
being tagged.
