gitk: Let git-rev-list do the argument list parsing
We use get_sha1() for -p (parent) objects, but still used
get_sha1_hex() for the tree. Just to be consistent, allow
extended SHA1 expression for the tree object name.
Note that this is not to encourage funky things like this:
git-commit-tree HEAD^{tree} -p HEAD

When we updated ls-tree recursive output to omit the tree nodes,
246cc52f38 adjusted the old test
so that we do not expect to see trees in its output. Later,
with 0f8f45cb4a, we added back the
ability to show both with -t option, but we forgot to update the
test as well.

The patch format shows complete rewrite as deletion of all old lines
followed by addition of all new lines. Count lines consistenly with
that when doing diffstat.

Foolishly I renamed diff.o around which caused an old diff.o
taken out of libgit.a and got linked into resulting binary and
exhibited mysterious breakage for many people. This borrows
from the kernel Makefile (scripts/Makefile.build) to first remove
the target and then recreate.
Signed-off-by: Junio C Hamano <junkio@cox.net>
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.

The set_reuse_addr() error case was the only error case in
socklist() where we returned rather than continued. Not sure
why. Either we must free the socklist, or continue. This patch
continues on error.

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.
Signed-off-by: Petr Baudis <pasky@suse.cz>
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 was useful in diagnosing the corrupt index.aux format
problem. But do not bother building or installing it by
default.

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 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
