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.

Currently, the vc-git-checkout function uses `git checkout' to fetch a
file from the git repository to the working copy. However, it is
completely ignoring the input argument that specifies the destination

git pack-refs
because while the first "pack-refs" does the right thing, the second

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

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
button 1. This works around the feature and allows selection to
work within the viewer just like it does on other less sane systems,
like Microsoft Windows.

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.

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.

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.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
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.

If the user selects a different branch from the Branch menu, or asks
us to create a new branch and immediately checkout that branch we
now perform the update of the working directory by way of a 2 way
read-tree invocation.
This emulates the behavior of `git checkout branch` or the behavior
of `git checkout -b branch initrev`. We don't however support the
-m style behavior, where a switch can occur with file level merging
performed by merge-recursive. Support for this is planned for a
future update.

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.

This makes git-fetch over git native protocol to automatically
decide to keep the downloaded pack if the fetch results in more
than 100 objects, just like receive-pack invoked by git-push

the downloaded pack as before.

configuration. We might want to introduce transfer.unpacklimit

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.

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

applications should be using to converse with the operating system.

Users may want to know what a file is before they add it to the

this is strictly advice to the user we won't bother to report
any failures from our attempt to run `file`.

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.

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.

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.
