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.

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

It also updates an outdated bit of the example in git-repo-config(1).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.

This uses git-rev-parse --no-revs --no-flags to give us just the

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

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.

git-log produces no output
fix pack-object buffer size
mailinfo: decode underscore used in "Q" encoding properly.
Reintroduce svn pools to solve the memory leak.
pack-objects: do not stop at object that is "too small"
git-commit --amend: two fixes.
get_tree_entry(): make it available from tree-walk
sha1_name.c: no need to include diff.h; tree-walk.h will do.
sha1_name.c: prepare to make get_tree_entry() reusable from others.
get_sha1() shorthands for blob/tree objects
pre-commit hook: complain about conflict markers.
git-merge: a bit more readable user guidance.
diff: move diff.c to diff-lib.c to make room.
git log: don't do merge diffs by default
Allow "git repack" users to specify repacking window/depth
Document git-clone --reference
Fix filename scaling for binary files
Fix uninteresting tags in new revision parsing
Conflicts:
Adjusted the addition of fmt-patch to match the recent split
from git.c to builtin.log.c.
Right now it split it into "builtin-log.c" for log-related commands
("log", "show" and "whatchanged"), and "builtin-help.c" for the
informational commands (usage printing and "help" and "version").
This just makes things easier to read, I find.

Because we sort the delta window by name-hash and then size,

When running "git commit --amend" only to fix the commit log
message without any content change, we mistakenly showed the
git-status output that says "nothing to commit" without
commenting it out.
If you have already run update-index but you want to amend the
top commit, "git commit --amend --only" without any paths should
have worked, because --only means "starting from the base
commit, update-index these paths only to prepare the index to
commit, and perform the commit". However, we refused -o without
paths.

This is an attempt to address the issue raised on #git channel
recently by Carl Worth.
After a conflicted automerge, "git diff" shows a combined diff
to give you how the tentative automerge result differs from
what came from each branch. During a complex merge, it is
tempting to be able to resolve a few paths at a time, mark
them "I've dealt with them" with git-update-index to unclutter
the next "git diff" output, and keep going. However, when the
final result does not compile or otherwise found to be a
mismerge, the workflow to fix the mismerged paths suddenly
changes to "git diff HEAD -- path" (to get a diff from our
HEAD before merging) and "git diff MERGE_HEAD -- path" (to get
a diff from theirs), and it cannot show the combined anymore.
With git-unresolve <paths>..., the versions from our branch and
their branch for specified blobs are placed in stage #2 and
stage #3, without touching the working tree files. This gives
you the combined diff back for easier review, along with
"diff --ours" and "diff --theirs".
One thing it does not do is to place the base in stage #1; this
means "diff --base" would behave differently between the run
immediately after a conflicted three-way merge, and the run
after an update-index by mistake followed by a git-unresolve.
We could theoretically run merge-base between HEAD and
MERGE_HEAD to find which tree to place in stage #1, but
reviewing "diff --base" is not that useful so....
