Teach fast-import to recursively copy files/directories
Fix git-p4 on Windows to not use the Posix sysconf function.
Correct trivial typo in fast-import documentation
Teach fast-import to recursively copy files/directories
Some source material (e.g. Subversion dump files) perform directory
renames by telling us the directory was copied, then deleted in the
same revision. This makes it difficult for a frontend to convert
such data formats to a fast-import stream, as all the frontend has
on hand is "Copy a/ to b/; Delete a/" with no details about what
files are in a/, unless the frontend also kept track of all files.
The new 'C' subcommand within a commit allows the frontend to make a
recursive copy of one path to another path within the branch, without
needing to keep track of the individual file paths. The metadata
copy is performed in memory efficiently, but is implemented as a
copy-immediately operation, rather than copy-on-write.
With this new 'C' subcommand frontends could obviously implement an
'R' (rename) on their own as a combination of 'C' and 'D' (delete),
but since we have already offered up 'R' in the past and it is a
trivial thing to keep implemented I'm not going to deprecate it.

git-svn: remove leading slashes from fetch lines in the generate config
We were previously sensitive to leading slashes in the fetch
lines and incorrectly writing them to the config if the user
used them (needlessly) in the command-line.
This fixes the issue and allows us to play nicely with legacy
configs that have leading slashes in fetch lines.
Thanks to Bradford Smith for figuring this out for me:

This script reads the existing commit log and .mailmap file,
and outputs author e-mail addresses that would map to more
than one names (most likely due to difference in the way they
are spelled, but some are due to ancient botched commits).
More permissive "git-rm --cached" behavior without -f.
In the previous behavior, "git-rm --cached" (without -f) had the same
restriction as "git-rm". This forced the user to use the -f flag in
situations which weren't actually dangerous, like:
$ git add foo # oops, I didn't want this
$ git rm --cached foo # back to initial situation
Previously, the index had to match the file *and* the HEAD. With
--cached, the index must now match the file *or* the HEAD. The behavior
without --cached is unchanged, but provides better error messages.

When I added the "--" case to the code scanning the arguments, I missed
the fact that since the switch statement uses -regexp, the "--" case
will match any argument containing "--", e.g. "--all". This fixes it
by taking out the -regexp (since we don't actually need regular
expression matching) and adjusting the match strings.
A side effect of this is that previously any argument starting with
"-d" would be taken to indicate date mode; now the argument has to be
exactly "-d" if you want date mode.

This adds an option (--window-memory=N) and configuration variable
(pack.windowMemory = N) to limit the memory size of the pack-objects
delta search window. This works by removing the oldest unpacked objects
whenever the total size goes above the limit. It will always leave
at least one object, though, so as not to completely eliminate the
possibility of computing deltas.
This is an extra limit on top of the normal window size (--window=N);
the window will not dynamically grow above the fixed number of entries
specified to fill the memory limit.
With this, repacking a repository with a mix of large and small objects
is possible even with a very large window.

Don't try to delta if target is much smaller than source
Add a new try_delta heuristic. Don't bother trying to make a delta if
the target object size is much smaller (currently 1/32) than the source,
as it's very likely not going to get a match. Even if it does, you will
have to read at least 32x the size of the new file to reassemble it,
which isn't such a good deal. This leads to a considerable performance
improvement when deltifying a mix of small and large files with a very
large window, because you don't have to wait for the large files to
percolate out of the window before things start going fast again.

apply delta depth bias to already deltified objects
We already apply a bias on the initial delta attempt with max_size being
a function of the base object depth. This has the effect of favoring
shallower deltas even if deeper deltas could be smaller, and therefore
creating a wider delta tree (see commits 4e8da195 and c3b06a69).
This principle should also be applied to all delta attempts for the same
object and not only the first attempt. With this the criteria for the
best delta is not only its size but also its depth, so that a shallower
delta might be selected even if it is larger than a deeper one. Even if
some deltas get larger, they allow for wider delta trees making the
depth limit less quickly reached and therefore better deltas can be
subsequently found, keeping the resulting pack size even smaller.
Runtime access to the pack should also benefit from shallower deltas.
Testing on different repositories showed slighter faster repacks,
smaller resulting packs, and a much nicer curve for delta depth
distribution with no more peak at the maximum depth level.
Improvements are even more significant with smaller depth limits.

This makes gitk more consistent with git rev-list and git log in its

now gitk displays an error message and quits, rather than treating it
as a revision and getting an error in the underlying git log. Now
gitk always passes "--" to git log even if no filenames are being
specified.
It also makes gitk display errors in invoking git log in a window
rather than on stderr, and makes gitk stop looking for a -d flag
when it sees a "--" argument.
Teach read-tree 2-way merge to ignore intermediate symlinks
Earlier in 16a4c61, we taught "read-tree -m -u" not to be
confused when switching from a branch that has a path frotz/filfre
to another branch that has a symlink frotz that points at xyzzy/
directory. The fix was incomplete in that it was still confused
when coming back (i.e. switching from a branch with frotz -> xyzzy/
to another branch with frotz/filfre).
This fix is rather expensive in that for a path that is created
we would need to see if any of the leading component of that
path exists as a symbolic link in the filesystem (in which case,
we know that path itself does not exist, and the fact we already
decided to check it out tells us that in the index we already
know that symbolic link is going away as there is no D/F
conflict).

branch --track: code cleanup and saner handling of local branches
This patch cleans up some complicated code, and replaces it with a
cleaner version, using code from remote.[ch], which got extended a
little in the process. This also enables us to fix two cases:
The earlier "fix" to setup tracking only when the original ref started
with "refs/remotes" is wrong. You are absolutely allowed to use a
separate layout for your tracking branches. The correct fix, of course,
is to set up tracking information only when there is a matching
remote.<nick>.fetch line containing a colon.
Another corner case was not handled properly. If two remotes write to

Support wholesale directory renames in fast-import
Some source material (e.g. Subversion dump files) perform directory
renames without telling us exactly which files in that subdirectory
were moved. This makes it hard for a frontend to convert such data
formats to a fast-import stream, as all the frontend has on hand

The new 'R' subcommand within a commit allows the frontend to

gitk: Use git log and add support for --left-right
This is based on patches from Linus Torvalds and Junio Hamano, so the
ideas here are theirs.
This makes gitk use "git log -z --pretty=raw" instead of "git rev-list"
to generate the list of commits, and also makes it grok the "<" and ">"
markers that git log (and git rev-list) output with the --left-right
flag to indicate which side of a symmetric diff a commit is reachable
from. Left-side commits are drawn with a triangle pointing leftwards
instead of a circle, and right-side commits are drawn with a triangle
pointing rightwards. The commitlisted list is used to store the
left/right information as well as the information about whether each
commit is on the boundary.
In commit 66e46f37de3ed3211a8ae0e8fc09c063bc3a1e08 I changed gitk to
store ids in rowrangelist and idrowranges rather than row numbers,
but I missed two places in the layouttail procedure. This resulted
in occasional errors such as the "can't read "commitrow(0,8572)":
no such element in array" error reported by Mark Levedahl. This fixes
it by using the id rather than the row number.
[PATCH] gitk: Fix for tree view ending in nested directories
Unroll the prefix stack when assigning treeheights when leaving
proc treeview. Previously, when the ls-tree output ended in
multiple nested directories (for instance in a repository with a
single file "foo/bar/baz"), $treeheight("foo/bar/") was assigned
twice, and $treeheight("foo/") was never assigned. This led to
an error when expanding the "foo" directory in the gitk treeview.

git-gui: Perform our own magic shbang detection on Windows
If we cannot locate a .exe for a git tool that we want to run than
it may just be a Bourne shell script as these are popular in Git.
In such a case the first line of the file will say "#!/bin/sh" so
a UNIX kernel knows what program to start to parse and run that.
But Windows doesn't support shbang lines, and neither does the Tcl
that comes with Cygwin.
We can pass control off to the git wrapper as that is a real Cygwin
program and can therefore start the Bourne shell script, but that is
at least two fork+exec calls to get the program running. One to do
the fork+exec of the git wrapper and another to start the Bourne shell
script. If the program is run multiple times it is rather expensive
as the magic shbang detection won't be cached across executions.
On MinGW/MSYS we don't have the luxury of such magic detection. The
MSYS team has taught some of this magic to the git wrapper, but again
its slower than it needs to be as the git wrapper must still go and
run the Bourne shell after it is called.
We now attempt to guess the shbang line on Windows by reading the
first line of the file and building our own command line path from
it. Currently we support Bourne shell (sh), Perl and Python. That
is the entire set of shbang lines that appear in git.git today.

We know that the version subcommand of git is special. It does not
currently have an executable link installed into $gitexecdir and we

So we forward any invocations to it directly to the git wrapper, as
it is a builtin within that executable.

for a rewritten commit can end up having duplicates. Instead of

information actually gets rewritten.
git-gui: Assume unfound commands are known by git wrapper
If we cannot locate a command in $gitexecdir on our own then it may
just be because we are supposed to run it by `git $name` rather than
by `git-$name`. Many commands are now builtins, more are likely to
go in that direction, and we may see the hardlinks in $gitexecdir go
away in future versions of git.

all of the heavy lifting; we have two proper Tcl lists ($cmd and

git-gui: Always use absolute path to all git executables
Rather than making the C library search for git every time we want
to execute it we now search for the main git wrapper at startup, do
symlink resolution, and then always use the absolute path that we
found to execute the binary later on. This should save us some
cycles, especially on stat challenged systems like Cygwin/Win32.
While I was working on this change I also converted all of our
existing pipes ([open "| git ..."]) to use two new pipe wrapper
functions. These functions take additional options like --nice
and --stderr which instructs Tcl to take special action, like
running the underlying git program through `nice` (if available)
or redirect stderr to stdout for capture in Tcl.

are in fact working, and give them a reasonable idea of when we may
finish.
We now do obtain that progress meter from read-tree -v and include
it in our main window's status bar. This allows users to see how
many files we have checked out, how many remain, and what percentage
of the operation is completed. It should help to keep users from
getting bored during a large checkout operation.

git-gui: Change the main window progress bar to use status_bar
Now that we have a fancy status bar mega-widget we can reuse that
within our main window. This opens the door for implementating
future improvements like a progress bar.

git-gui: Extract blame viewer status bar into mega-widget
Our blame viewer has had a very fancy progress bar at the bottom of
the window that shows the current status of the blame engine, which
includes the number of lines completed as both a text and a graphical
meter. I want to reuse this meter system in other places, such as
during a branch switch where read-tree -v can give us a progress
meter for any long-running operation.
This change extracts the code and refactors it as a widget that we
can take advantage of in locations other than in the blame viewer.

git-gui: Allow double-click in checkout dialog to start checkout
If the user double clicks a branch in the checkout dialog then they
probably want to start the checkout process on that branch. I found
myself doing this without realizing it, and of course it did nothing
as there was no action bound to the listbox's Double-Button-1 event
handler. Since I did it without thinking, others will probably also
try, and expect the same behavior.

If we have specifications listed in our revision picker mega-widget
then we should default the selection within that widget to the first
ref available. This way the user does not need to use the spacebar
to activate the selection of a ref within the box; instead they can
navigate up/down with the arrow keys and be done with it.

git-gui: Unabbreviate commit SHA-1s prior to display
If the end-user feeds us an abbreviated SHA-1 on the command line for
`git gui browser` or `git gui blame` we now unabbreviate the value
through `git rev-parse` so that the title section of the blame or
browser window shows the user the complete SHA-1 as Git determined
it to be.
If the abbreviated value was ambiguous we now complain with the
standard error message(s) as reported by git-rev-parse --verify,
so that the user can understand what might be wrong and correct
their command line.

git-gui: Refactor branch switch to support detached head
This is a major rewrite of the way we perform switching between
branches and the subsequent update of the working directory. Like
core Git we now use a single code path to perform all changes: our
new checkout_op class. We also use it for branch creation/update
as it integrates the tracking branch fetch process along with a
very basic merge (fast-forward and reset only currently).
Because some users have literally hundreds of local branches we
use the standard revision picker (with its branch filtering tool)
to select the local branch, rather than keeping all of the local
branches in the Branch menu. The branch menu listing out all of
the available branches is simply not sane for those types of huge
repositories.
Users can now checkout a detached head by ticking off the option
in the checkout dialog. This option is off by default for the
obvious reason, but it can be easily enabled for any local branch
by simply checking it. We also detach the head if any non local
branch was selected, or if a revision expression was entered.

It seems that not everybody expects a difference between keeping a "pick"
line, and deleting it. So be a bit more explicit about that, with all
capitals to get the attention.

rebase -i: remember the settings of -v, -s and -p when interrupted
After interruption, be that an edit, or a conflicting commit, reset
the variables VERBOSE, STRATEGY and PRESERVE_MERGES, so that the
user does not have to respecify them with "rebase --continue".

rebase -i: actually show the diffstat when being verbose
The "while" loop in the function do_rest is not supposed to ever be
exited. Instead, the function do_one checks if there is nothing left,
and cleans up and exits if that is the case. So the diffstat code
belongs there.
