This fixes the Tk error "wrong # coordinates: expected 0 or 4, got 2"
that sometimes occurred when reloading. The problem was that we didn't
unset the variables containing the canvas item id numbers for the
displayed rows when we cleared the canvases. Thus make_secsel would
think it had something to do when it didn't.
Thanks to Michele Ballabio for finding a way to trigger the bug
reliably.
builtin-apply: do not declare patch is creation when we do not know it
When we see no context nor deleted line in the patch, we used to declare
that the patch creates a new file. But some people create an empty file
and then apply a patch to it. Similarly, a patch that delete everything
is not a deletion patch either.
This commit corrects these two issues. Together with the previous commit,
it allows a diff between an empty file and a line-ful file to be treated
as both creation patch and "add stuff to an existing empty file",
depending on the context. A new test t4126 demonstrates the fix.
t0050: Fix merge test on case sensitive file systems
On a case sensitive filesystem, "git reset --hard" might refuse to
overwrite a file whose name differs only by case, even if
core.ignorecase is set. It is not clear which circumstances cause this
behavior. This commit simply works around the problem by removing
the case changing file before running "git reset --hard".

A patch from a foreign SCM (or plain "diff" output) often have both
preimage and postimage filename on ---/+++ lines even for a patch that
creates a new file. However, when there is a filename for preimage, we
used to insist the file to exist (either in the work tree and/or in the
index). When we cannot be sure by parsing the patch that it is not a
creation patch, we shouldn't complain when if there is no such a file.
This commit fixes the logic.
Refactor the code that validates the preimage file into a separate
function while we are at it, as it is getting rather big.

cvsexportcommit: introduce -W for shared working trees (between Git and CVS)
If you have a CVS checkout, it is easy to import the CVS history by
calling "git cvsimport". However, interacting with the CVS repository
using "git cvsexportcommit" was cumbersome, since that script assumes
separate working directories for Git and CVS.
Now, you can call cvsexportcommit with the -W option. This will
automatically discover the GIT_DIR, and it will check out the parent
commit before exporting the commit.
The intended workflow is this:
$ CVSROOT=$URL cvs co module
$ cd module
$ git cvsimport

dirty submodules, since they are not updated by those actions anyway.

let pack-objects do the writing of unreachable objects as loose objects
Commit ccc1297226b184c40459e9d373cc9eebfb7bd898 changed the behavior
of 'git repack -A' so unreachable objects are stored as loose objects.
However it did so in a naive and inn efficient way by making packs
about to be deleted inaccessible and feeding their content through
'git unpack-objects'. While this works, there are major flaws with
this approach:
- It is unacceptably sloooooooooooooow.
In the Linux kernel repository with no actual unreachable objects,
doing 'git repack -A -d' before:
real 2m33.220s
user 2m21.675s
sys 0m3.510s
And with this change:
real 0m36.849s
user 0m24.365s
sys 0m1.950s
For reference, here's the timing for 'git repack -a -d':
real 0m35.816s
user 0m22.571s
sys 0m2.011s
This is explained by the fact that 'git unpack-objects' was used to
unpack _every_ objects even if (almost) 100% of them were thrown away.
- There is a black out period.
Between the removal of the .idx file for the redundant pack and the
completion of its unpacking, the unreachable objects become completely
unaccessible. This is not a big issue as we're talking about unreachable
objects, but some consistency is always good.
- There is no way to easily set a sensible mtime for the newly created
unreachable loose objects.
So, while having a command called "pack-objects" to perform object
unpacking looks really odd, this is probably the best compromize to be
able to solve the above issues in an efficient way.

filter-branch tries to restore "old" copies of some
environment variables by using the construct:
unset var
test -z "$old_var" || var="$old_var" && export var
This is just wrong. AND-list and OR-list operators && and || have equal
precedence and they bind left to right. The second term, var="$old"
assignment always succeeds, so we always end up exporting var.
On bash and dash, exporting an unset variable has no effect. However, on
some shells (such as FreeBSD's /bin/sh), the shell exports the empty
value.
This manifested itself in this case as git-filter-branch setting
GIT_INDEX_FILE to the empty string, which in turn caused its call to
git-read-tree to fail, leaving the working tree pointing at the original
HEAD instead of the rewritten one.
To fix this, we change the short-circuit logic to better match the intent:
test -z "$old_var" || {
var="$old_var" && export var
}

Now that repack -A will leave unreferenced objects unpacked, there is
no reason to use the -a option to repack (which will discard unreferenced
objects). The unpacked unreferenced objects will not be repacked by a
subsequent repack, and will eventually be pruned by git-gc based on the
gc.pruneExpire config option.
repack: modify behavior of -A option to leave unreferenced objects unpacked
The previous behavior of the -A option was to retain any previously
packed objects which had become unreferenced, and place them into the newly
created pack file. Since git-gc, when run automatically with the --auto
option, calls repack with the -A option, this had the effect of retaining
unreferenced packed objects indefinitely. To avoid this scenario, the
user was required to run git-gc with the little known --prune option or
to manually run repack with the -a option.
This patch changes the behavior of the -A option so that unreferenced
objects that exist in any pack file being replaced, will be unpacked into
the repository. The unreferenced loose objects can then be garbage collected
by git-gc (i.e. git-prune) based on the gc.pruneExpire setting.
Also add new tests for checking whether unreferenced objects which were
previously packed are properly left in the repository unpacked after
repacking.

gitk: Show current row number and total number of rows
This adds a couple of fields in the bar just below the upper panes
that show the row number of the currently selected commit, and how
many rows are displayed in total. The latter increments as commits
are read in, and thus functions to show that progress is being made.
This therefore also removes the code that showed progress using a
green oscillating bar in the progress bar window (which some people
disliked).
This is the base for making symlink detection in the middle fo a pathname
saner and (much) more efficient.
Under various loads, we want to verify that the full path leading up to a
filename is a real directory tree, and that when we successfully do an
'lstat()' on a filename, we don't get a false positive due to a symlink in
the middle of the path that git should have seen as a symlink, not as a
normal path component.
The 'has_symlink_leading_path()' function already did this, and cached
a single level of symlink information, but didn't cache the _lack_ of a
symlink, so the normal behaviour was actually the wrong way around, and we
ended up doing an 'lstat()' on each path component to check that it was a
real directory.
This caches the last detected full directory and symlink entries, and
speeds up especially deep directory structures a lot by avoiding to
lstat() all the directories leading up to each entry in the index.
[ This can - and should - probably be extended upon so that we eventually
never do a bare 'lstat()' on any path entries at *all* when checking the
index, but always check the full path carefully. Right now we do not
generally check the whole path for all our normal quick index
revalidation.
We should also make sure that we're careful about all the invalidation,
ie when we remove a link and replace it by a directory we should
invalidate the symlink cache if it matches (and vice versa for the
directory cache).
But regardless, the basic function needs to be sane to do that. The old
'has_symlink_leading_path()' was not capable enough - or indeed the code
readable enough - to really do that sanely. So I'm pushing this as not
just an optimization, but as a base for further work. ]

if (file_exists(p->path))
add_file_to_cache(p->path, 0);
where both "file_exists()" and "add_file_to_cache()" needed to do a
lstat() on the path to do their work.
This cuts down 'lstat()' calls for the partial commit case by two
for each path we know about (because we do this twice per path).
Just move the lstat() to the caller instead (that's all that
"file_exists()" really does), and pass the stat information down to the
add_to_cache() function.
This essentially makes 'add_to_index()' the core function that adds a path
to the index, getting the index pointer, the pathname and the stat
information as arguments. There are then shorthand helper functions that
use this core function:
- 'add_to_cache()' is just 'add_to_index()' with the default index
- 'add_file_to_cache/index()' is the same, but does the lstat() call
itself, so you can pass just the pathname if you don't already have the
stat information available.
So old users of the 'add_file_to_xyzzy()' are essentially left unchanged,
and this just exposes the more generic helper function that can take
existing stat information into account.

This goes back to the method of doing updates where we translate the
revisions we're given to SHA1 ids and then remove the ones we've asked
for before or that we've already come across. This speeds up updates
enormously in most cases since it means git log doesn't have to traverse
large parts of the tree. We used to do this, but it had bugs, and commit 468bcaedbb1589f16955e63b6bfba01c2f53e433 (gitk: Don't filter view
arguments through git rev-parse) went to the slower method to avoid the
bugs.
In order to do this properly, we have to parse the command line and
understand all the flag arguments. So this adds a parser that checks
all the flag arguments. If there are any we don't know about, we
disable the optimization and just pass the whole lot to git log
(except for -d/--date-order, which we remove from the list).
With this we can then use git rev-parse on the non-flag arguments to
work out exactly what SHA1 ids are included and excluded in the list,
which then enables us to ask for just the new ones when updating.
One wrinkle is that we have to turn symmetric diff arguments (of the
form a...b) back into symmetric diff form so that --left-right still
works, as git rev parse turns a...b into a b ^merge_base(a,b).
