Not that this makes practical performance difference; the kernel tree
for example has 200 or so directories that have subdirectory, and the
largest ones have 57 of them (fs and drivers). With a test to apply
600 patches with git-apply and git-write-tree, this did not make more
than one per-cent of a difference, but it is a good cleanup.

This patch partly changes the background color for remote refs.
It makes it easy to quickly distinguish remote refs from local
developer branches.
I ignore remote HEADs, as these really should be drawn as
aliases to other heads. But there is no simple way to
detect that HEADs really are aliases for other refs via
"git-ls-remote".

This allows the user to change the name of the view, whether it is
permanent, and the list of files/directories for the view.
Signed-off-by: Paul Mackerras <paulus@samba.org>
With this the user can now mark a view as "permanent" and it will
appear in the list every time gitk is started (until it is deleted).
Also tidied up the view definition window, and changed the view
menu to use radiobuttons for the view selections so there is some
feedback as to which is the current view.

This has been an unfortunate sideway in the git API evolution.
We use git-repo-config for all the other .git/config interaction
so let's also use git-repo-config -l for the variable listing.

This adds git-repo-config --list (or git-repo-config -l) support,
similar to what git-var -l does now (to be phased out so that we
have a single sane interface to the config file instead of fragmented
and confused API).

This patch splits the diff-delta interface into index creation and delta
generation. A wrapper is provided to preserve the diff-delta() call.
This will allow for an optimization in pack-objects.c where the source
object could be fixed and a full window of objects tentatively tried
against
that same source object without recomputing the source index each time.
This patch only restructure things, plus a couple cleanups for good
measure. There is no performance change yet.

This patch adds a Documentation/config.txt file included by git-repo-config
and currently aggregating hopefully all the available git plumbing / core
porcelain configuration variables, as well as briefly describing the format.
It also updates an outdated bit of the example in git-repo-config(1).

Currently, if git-rev-parse encounters an argument that is neither a
recognizable revision name nor the name of an existing file or
directory, and it hasn't encountered a "--" argument, it prints an
error message saying "No such file or directory". This can be
confusing for users, including users of programs such as gitk that
use git-rev-parse, who may then think that they can't ask about the
history of files that no longer exist.
This makes it print a better error message, one that points out the
ambiguity and tells the user what to do to fix it.

We reused the cache-tree data without verifying the tree object
still exists. Recompute in cache_tree_update() an otherwise
valid cache-tree entry when the tree object disappeared.
This is not usually a problem, but theoretically without this
fix things can break when the user does something like this:
- read-index from a side branch
- write-tree the result
- remove the side branch with "git branch -D"
- remove the unreachable objects with "git prune"
- write-tree what is in the index.

This updates git-apply to maintain cache-tree information. With
this and the previous write-tree patch, repeated "apply --index"
followed by "write-tree" on a huge tree will hopefully become
faster.
Signed-off-by: Junio C Hamano <junkio@cox.net>
The updated write-tree reads from $GIT_DIR/index.aux to pick up
subtree objects information, updates the cache-tree with the
index, and updates index.aux file after writing a tree out of
the index file.
Until update-index and other programs that modify the index are
updated to maintain index.aux file, the index.aux file written
by the last write-tree will become stale immediately after they
update the index, which will result in the whole tree
recomputation just like the original write-tree.
The idea is to convert those commands to invalidate cache-tree
whenever they touch the index entries, and write updated
index.aux out. After the index is updated with them, write-tree
will be able to reuse the parts of the cache-tree that have not
been touched.
Signed-off-by: Junio C Hamano <junkio@cox.net>
The cache_tree data structure is to cache tree object names that
would result from the current index file.
The idea is to have an optional file to record each tree object
name that corresponds to a directory path in the cache when we
run write_cache(), and read it back when we run read_cache().
During various index manupulations, we selectively invalidate
the parts so that the next write-tree can bypass regenerating
tree objects for unchanged parts of the directory hierarchy.
We could perhaps make the cache-tree data an optional part of
the index file, but that would involve the index format updates,
so unless we need it for performance reasons, the current plan
is to use a separate file, $GIT_DIR/index.aux to store this
information and link it with the index file with the checksum
that is already used for index file integrity check.

read_cache_1() and write_cache_1() takes an extra parameter
*sha1 that returns the checksum of the index file when non-NULL.

This uses git-rev-parse --no-revs --no-flags to give us just the
file and directory names on the command line, so that we can create
the "Command line" view if any were specified. All other arguments
just get passed to git-rev-list (without a pass through git-rev-parse).

This is a fix for a problem reported by Jim Radford where an argument
list somewhere overflows on repositories with lots of tags. In fact
it's now unnecessary to use git-rev-parse since git-rev-list can take
all the arguments that git-rev-parse can. This is inspired by but not
the same as the solutions suggested by Jim Radford and Linus Torvalds.

"diff-index -m" does not mean "do not ignore merges", but means
"pretend missing files match the index".
The previous round tried to address this, but failed because
setup_revisions() ate "-m" flag before the caller had a chance

Signed-off-by: Junio C Hamano <junkio@cox.net>
This is the first installment to libify diff brothers.
The updated diff-files uses revision.c::setup_revisions()
infrastructure to parse its command line arguments, which means
the pathname arguments are checked more strictly than before.
The tests are adjusted to separate possibly missing paths from
the rest of arguments with double-dashes, to show the kosher
way.
As Linus pointed out, renaming diff.c to diff-lib.c was simply
stupid, so I am renaming it back. The new diff-lib.c is to
contain pieces extracted from diff brothers.
