It seems that git prune changed behaviour with respect to revisions added
from command line, probably when it became a builtin. Currently, it prints
a short usage and exits: instead, it should take those revisions into
account and not prune them. So add a couple of test to point this out.
We'll be fixing this by switching to parse_options(), so add tests to
detect bogus command line parameters as well, to keep ourselves from
introducing regressions.

git-p4: Use P4EDITOR environment variable when set

git-p4: Optimize the fetching of data from perforce.
We tightened the refspec validation code in an earlier commit ef00d15
(Tighten refspec processing, 2008-03-17) per my suggestion, but the
suggestion was misguided to begin with and it broke this usage:
$ git push origin HEAD~12:master
The syntax of push refspecs and fetch refspecs are similar in that they
are both colon separated LHS and RHS (possibly prefixed with a + to
force), but the similarity ends there. For example, LHS in a push refspec
can be anything that evaluates to a valid object name at runtime (except
when colon and RHS is missing, or it is a glob), while it must be a
valid-looking refname in a fetch refspec. To validate them correctly, the
caller needs to be able to say which kind of refspecs they are. It is
unreasonable to keep a single interface that cannot tell which kind it is
dealing with, and ask it to behave sensibly.
This commit separates the parsing of the two into different functions, and
clarifies the code to implement the parsing proper (i.e. splitting into
two parts, making sure both sides are wildcard or neither side is).
This happens to also allow pushing a commit named with the esoteric "look
for that string" syntax:

Make revision limiting more robust against occasional bad commit dates
The revision limiter uses the commit date to decide when it has seen
enough commits to finalize the revision list, but that can get confused
if there are incorrect dates far in the past on some commits.
This makes the logic a bit more robust by
- we always walk an extra SLOP commits from the source list even if we
decide that the source list is probably all done (unless the source is
entirely empty, of course, because then we really can't do anything at
all)
- we keep track of the date of the last commit we added to the
destination list (this will *generally* be the oldest entry we've seen
so far)
- we compare that with the youngest entry (the first one) of the source
list, and if the destination is older than the source, we know we want
to look at the source.
which causes occasional date mishaps to be handled cleanly.

Fix possible Solaris problem in 'checkout_entry()'
Currently when checking out an entry "path", we try to unlink(2) it first

error return from this unlink because there may not even be any file

However if you are root on Solaris, you can unlink(2) a directory
successfully and corrupt your filesystem.
This moves the code around and check the directory first, and then

When your test creates an unwritable directory that test framework cannot
clean out by "rm -fr trash", later tests cannot start in a fresh state
they expect to. Detect this and error out early.
When a merge result creates a new file, and when our side already has a
file in the path, taking the merge result may clobber the untracked file.
However, the logic to detect this situation was totally the wrong way. We
should complain when the file exists, not when the file does not exist.
In commit 34110cd4e394e3f92c01a4709689b384c34645d8 ("Make 'unpack_trees()'
have a separate source and destination index") I introduced a really
stupid bug in that it would always add merged entries with the CE_UPDATE
flag set. That caused us to always re-write the file, even when it was
already up-to-date in the source index.
Not only is that really stupid from a performance angle, but more
importantly it's actively wrong: if we have dirty state in the tree when
we merge, overwriting it with the result of the merge will incorrectly
overwrite that dirty state.
This trivially fixes the problem - simply don't set the CE_UPDATE flag
when the merge result matches the old state.

format-patch: generate MIME header as needed even when there is format.header
Earlier, the callchain from pretty_print_commit() down to pp_title_line()
had an unwarranted assumption that the presense of "after_subject"
parameter, means the caller has already output MIME headers for
attachments. The parameter's primary purpose is to give extra header
lines the caller wants to place after pp_title_line() generates the
"Subject: " line.
This assumption does not hold when the user used the format.header
configuration variable to pass extra headers, and caused a message with
non-ASCII character to lack proper MIME headers (e.g. 8-bit CTE header).
The earlier logic also failed to suppress duplicated MIME headers when
"format-patch -s --attach" is asked for and the signer's name demanded
8-bit clean transport.
This patch fixes the logic by introducing a separate need_8bit_cte
parameter passed down the callchain. This can have one of these values:
-1 : we've already done MIME crap and we do not want to add extra header
to say this is 8bit in pp_title_line();
0 : we haven't done MIME and we have not seen anything that is 8bit yet;
1 : we haven't done MIME and we have seen something that is 8bit;
pp_title_line() must add MIME header.
It adds two tests by Jeff King who independently diagnosed this issue.

Damn, this series has had more subtle issues than I ever expected.
'git stash' creates its saved working tree object with:
# state of the working tree
w_tree=$( (
rm -f "$TMP-index" &&
cp -p ${GIT_INDEX_FILE-"$GIT_DIR/index"} "$TMP-index" &&
GIT_INDEX_FILE="$TMP-index" &&
export GIT_INDEX_FILE &&
git read-tree -m $i_tree &&
git add -u &&
git write-tree &&
rm -f "$TMP-index"
) ) ||
die "Cannot save the current worktree state"
which creates a new index file with the updates, and writes the tree from
that.
We have this logic where we compare the timestamp of the index with the
timestamp of the files and we then write them out "smudged" if they are
the same, and it basically depends on the fact that the date on the index
file is compared with the date encoded in the stat information itself.
And what is going on is:
- we create a new index file with that "cp". We are careful to preserve
the timestamps by using "-p", so this one should be all ok.
- then we *update* that index by resetting it to the tree with git
read-tree, but now we do *not* preserve the timestamp on this new copy
any more, even though we copy over all the timestamps on the files that
are indexed from the stat information!
Now, we always had that problem when re-writing the index, but we had this
clever workaround in the writing part: if the source had racily clean
entries, then when we wrote those out (and thus can't depend on the index
fiel timestamp showing that they are racily clean any more!), we would
smudge them when writing.
IOW, we handle this issue by having write_index() do this:
for (i = 0; i < entries; i++) {
...
if (is_racy_timestamp(istate, ce))
ce_smudge_racily_clean_entry(ce);
..
when writing out entries. And that all took care of it, because now when
we wrote the new index, we'd change the timestamp on the index, yes, but
we'd smudge the entries we wrote out, so now the resulting index would
still show that file as not-up-to-date any more.
But with commit 34110cd4e394e3f92c01a4709689b384c34645d8 ("Make
'unpack_trees()' have a separate source and destination index"), this
logic no longer triggers, because we now write out the "result" index, and
that one never got its timestamp updated from the source index, so it had
lost all that "is_racy_timestamp()" information!
This trivial patch fixes it. It looks trivial, and it's a simple fix, but
boy did it take me way too much thinking and explaining to myself to
explain why there was a problem in the first place!
The trivial fix is to just copy the index timestamp from the source index
into the result index. But we only do this if we *have* a source index, of
course, and if we will even bother to use the result.

The Apple menu is actually not the menu with the Apple corporate
logo, but the menu next to it, which shows the name of the
application and is typically called the application menu. Most users
of git-gui see this menu titled as "Git Gui". The actual label of
this menu comes from our Info.plist file and cannot be specified

I think it would make more sense for rev~ to have the same guarantees that
rev^ has, namely to always return a commit. I would also suggest that not
giving a number would have the same effect of defaulting to 1, not 0.
Right now it's a bit illogical, but at least it's an _undocumented_
illogical behaviour.
This patch makes '^' and '~' act the same for the default count (i.e. both
default to 1), and also have the same behaviour for a count of zero.

web--browse: use custom commands defined at config time
Currently "git web--browse" is restricted to a set of commands defined
in the script. You can subvert the "browser.<tool>.path" to force "git

whose invocation syntax does not match one of the current tools then
you would have to write a wrapper script for it.
This patch adds a git config variable "browser.<tool>.cmd" which
allows a more flexible browser choice.
If you run "git web--browse" with -t/--tool, -b/--browser or the
"web.browser" config variable set to an unrecognized tool then "git
web--browse" will query the "browser.<tool>.cmd" config variable. If
this variable exists, then "git web--browse" will treat the specified
tool as a custom command and will use a shell eval to run the command
with the URLs added as extra parameters.

File mode changes should be handled similarly to changes of content.

conflict.
