The original intention of 72909be (Add diff-option --ext-diff, 2007-06-30)
was to optionally allow the use of external diff viewer in "git log"
family (while keeping them disabled by default). It exposed the "allow
external diff" bit to the UI, but forgot to adjust the "git diff" codepath
that was set up to always allow use of the external diff viewer.

error: unable to create temporary sha1 filename ./objects/15: File exists
mkstemp can fail for many reasons, one of which, ENOENT, can occur if
the directory for the temp file doesn't exist. create_tmpfile tried to
handle this case by always trying to mkdir the directory, even if it
already existed. This caused errno to be clobbered, so one cannot tell
why mkstemp really failed, and it truncated the buffer to just the
directory name, resulting in the strange error message shown above.
Note that in both occasions that I've seen this failure, it has not been
due to a missing directory, or bad permissions, but some other, unknown
mkstemp failure mode that did not occur when I ran git again. This code
could perhaps be made more robust by retrying mkstemp, in case it was a
transient failure.

While static commands are already useful, some tools need
additional parameters to reach maximum usability. This
commit adds support for passing them one revision name
parameter, and one arbitrary string. With this addition,
the tools menu becomes flexible enough to implement basic
rebase support:

[guitool "Rebase/Continue"]

[guitool "Rebase/Start..."]
cmd = git rebase $ARGS $REVISION $CUR_BRANCH
title = Start Rebase
prompt = Rebase Current Branch
argprompt = Flags
revprompt = New Base
revunmerged = yes

not included in the Add dialog to avoid clutter. Also, the

Due to the emphasis on scriptability in the git

This problem can be mitigated by providing basic

The interface is powerful enough to allow calling

git-gui: Fix the after callback execution in rescan.
The rescan function receives a callback command
as its parameter, which is supposed to be executed
after the scan finishes. It is generally used to
update status. However, rescan may initiate a
loading of a diff, which always calls ui_ready after
completion. If the after handler is called before
that, ui_ready will override the new status.
This commit ensures that the after callback is
properly threaded through the diff machinery.
Since it uncovered the fact that force_first_diff
actually didn't work due to an undeclared global
variable, and the desired effects appeared only
because of the race condition between the diff
system and the rescan callback, I also reimplement
this function to make it behave as originally
intended.

The space between the commit and the source attribute is not easily
machine-parseable: if we combine --source with --parents and give a SHA1
as a starting point, it's unnecessarily hard to see where the list of
parents ends and the source decoration begins.
Example:
git show --parents --source $(git rev-list HEAD)
which is admittedly contrived, but can easily happen in scripting.
So use a <tab> instead of a space as the source separator.
The other decorations didn't have this issue, because they were surrounded
by parenthesis, so it's obvious that they aren't parent SHA1's.
It so happens that _visually_ this makes no difference for "git log
--source", since "commit <40-char SHA1>" is 47 characters, so both a space
and a <tab> will end up showing as a single commit. Of course, with
'--pretty=oneline' or '--parents' or '--abbrev-commit' you'll see the
difference.

Teach ls-files --with-tree=<tree> to work with options other than -c
Originally --with-tree=<tree> was designed for the sole purpose of
checking if a given pathspec makes sense as a parameter to git-commit
using it in conjunction with --error-unmatch. It had logic to avoid
showing the same entry (one came from the original index, another from the
overlayed tree) twice so that it works with -c (i.e. "show-cached"), but
otherwise it was not designed to work with the flags such as -m, -d, etc.
This teaches the same logic to cover the codepath for -m and -d.

SVN itself always stores log messages in the repository as
UTF-8. git always stores/retrieves everything as raw binary
data with no transformations whatsoever.
To interact with SVN, we need to encode log messages as UTF-8
before sending them to SVN, as SVN cannot do it for us. When
retrieving log messages from SVN, we also need to (attempt to)
reencode the UTF-8 log message back to the user-specified commit
encoding.
Note, handling i18n.logoutputencoding for "git svn log" also
needs to be done in a future change.
Also, this change only deals with the encoding of commit
messages and nothing else (path names, blob content, ...).

date/time: do not get confused by fractional seconds
The date/time parsing code was confused if the input time HH:MM:SS is
followed by fractional seconds. Since we do not record anything finer
grained than seconds, we could just drop fractional part, but there is a
twist.
We have taught people that not just spaces but dot can be used as word
separators when spelling things like:
$ git log --since 2.days
$ git show @{12:34:56.7.days.ago}
and we shouldn't mistake "7" in the latter example as a fraction and
discard it.
The rules are:
- valid days of month/mday are always single or double digits.
- valid years are either two or four digits
No, we don't support the year 600 _anyway_, since our encoding is based
on the UNIX epoch, and the day we worry about the year 10,000 is far
away and we can raise the limit to five digits when we get closer.
- Other numbers (eg "600 days ago") can have any number of digits, but
they cannot start with a zero. Again, the only exception is for
two-digit numbers, since that is fairly common for dates ("Dec 01" is
not unheard of)
So that means that any milli- or micro-second would be thrown out just
because the number of digits shows that it cannot be an interesting date.
A milli- or micro-second can obviously be a perfectly fine number
according to the rules above, as long as it doesn't start with a '0'. So
if we have
12:34:56.123
then that '123' gets parsed as a number, and we remember it. But because
it's bigger than 31, we'll never use it as such _unless_ there is
something after it to trigger that use.
So you can say "12:34:56.123.days.ago", and because of the "days", that
123 will actually be meaninful now.

gitk: Fix linehtag undefined error with file highlighting
Occasionally gitk will throw a Tcl error complaining that linehtag(n)
is undefined when. It happens when the commit list is still growing
(e.g. when updating the commit list) and gitk is set to highlight
commits that affect certain file(s). What happens is that the changes
to the commit list set need_redisplay to indicate that the display
needs to be redrawn. That causes the next call to drawcommits to call
clear_display, which unsets iddrawn and thus ensures that readfhighlight
won't call bolden on any rows that have moved. However, it is possible
for readfhighlight to be called after the commit list has changed but
before drawcommits has run, meaning that readfhighlight will potentially
think that rows have been drawn when they haven't, because of the
change in the id -> row mapping (and the fact that iddrawn is indexed
by id but line[hnd]tag are indexed by row number).
This fixes it (and also optimizes things a little) by making bolden
and bolden_name check need_redisplay before doing anything. If
need_redisplay is set, then there is no point doing anything because
the whole display is about to get cleared and redrawn, and it avoids
looking up line[hn]tag using stale row numbers.
This commit fixes two problems with commit encodings:
1) git-log actually uses i18n.logoutputencoding to generate
its output, and falls back to i18n.commitencoding only
when that option is not set. Thus, gitk should use its
value to read the results, if available.
2) The readcommit function did not process encodings at all.
This led to randomly appearing misconverted commits if
the commit encoding differed from the current locale.
Now commit messages should be displayed correctly, except
when logoutputencoding is set to an encoding that cannot
represent charecters in the message. For example, it is
impossible to convert Japanese characters from Shift-JIS
to CP-1251 (although the reverse conversion works).
The reason for using git log to read the commit and then getting
Tcl to convert its output is that is essentially what happens in
the normal path through getcommitlines, hence there is less chance
for unintended differences in how commits are processed in
getcommitlines and do_readcommit.

Earlier commit 5521883 (checkout: do not lose staged removal, 2008-09-07)
tightened the rule to prevent switching branches from losing local
changes, so that staged removal of paths can be protected, while
attempting to keep a loophole to still allow a special case of switching
out of an un-checked-out state.
However, the loophole was made a bit too tight, and did not allow
switching from one branch (in an un-checked-out state) to check out
another branch.
The change to builtin-checkout.c in this commit loosens it to allow this,
by not insisting the original commit and the new commit to be the same.
It also introduces a new function, is_index_unborn (and an associated
macro, is_cache_unborn), to check if the repository is truly in an
un-checked-out state more reliably, by making sure that $GIT_INDEX_FILE
did not exist when populating the in-core index structure. A few places
the earlier commit 5521883 added the check for the initial checkout
condition are updated to use this function.
When the "-v" option is given, we put diff of what is to be committed into
the commit template, and then strip it back out again after the user has
edited it.
We used to look for the diff by searching for the "diff --git a/"
header. With diff.mnemonicprefix set in the configuration, however, this
pattern does not match. The pattern is loosened to cover this case.
Also, if the user puts their own diff in the message (e.g., as a sample
output), then we will accidentally trigger the pattern, removing part of
their output.
We can avoid doing this stripping altogether if the user didn't use "-v"
in the first place, so we know that any match we find will be a false
positive.
