gitk: Let git-rev-list do the argument list parsing
commit-tree: allow generic object name for the tree as well.
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:
When we updated ls-tree recursive output to omit the tree nodes, 246cc52f388cae8ca99e5a12b8458c9bfa467765 adjusted the old test
so that we do not expect to see trees in its output. Later,
with 0f8f45cb4a7e664b396f73c25891da46b953b8b8, 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.
Makefile: remove and create libgit.a from scratch.
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.
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".

gitk: Implement "permanent" views (stored in ~/.gitk)
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.
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.

Deprecate usage of git-var -l for getting config vars list
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).
rev-parse: better error message for ambiguous arguments
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.
Invalidate cache-tree entries for touched paths in git-apply.
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.
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.
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.
gitk: Use git-rev-parse only to identify file/dir names on cmd line
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).
gitk: Let git-rev-list do the argument list parsing
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.
make update-index --chmod work with multiple files and --stdin
The patch makes "--chmod=-x" and "--chmod=+x" act like "--add"
and "--remove" to affect the behaviour of the command for the
rest of the path parameters, not just the following one.
The second installment to libify diff brothers. The pathname
arguments are checked more strictly than before because we now
use the revision.c::setup_revisions() infrastructure.
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.
I hacked it up to teach it the git extended diff headers, made
it not to read the whole patch in the array.
Also, the original program, when arguments are given, ran "diff"
with the given arguments and showed the output from it. Of
course, I changed it to run "git diff" ;-).

Adjusted the addition of fmt-patch to match the recent split

Split up builtin commands into separate files from git.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.

Quoted-Printable (RFC 2045) and the "Q" encoding (RFC 2047) are
subtly different; the latter is used on the mail header and an
underscore needs to be decoded to 0x20.
pack-objects: do not stop at object that is "too small"
Because we sort the delta window by name-hash and then size,
hitting an object that is too small to consider as a delta base
for the current object does not mean we do not have better
candidate in the window beyond it.
Noticed by Shawn Pearce, analyzed by Nico, Linus and me.
When moving backwards or forwards through the history list, this
automatically switches the view so that each point that we jump to
is shown in the same view that it was originally displayed in.
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.
I tried the code with pack-objects.c::try_delta(), and was
somewhat dissapointed. The current type-path based heuristics
already limits the delta attempts to similar objects anyway, so
it is not a good place to apply it.
The Net never forgets, so we can resurrect it if we wanted to
later.
When a verbatim rename or copy is detected, we did not show
anything on the "diff --stat" for the filepair. This makes it
to show the rename information.

git log: don't do merge diffs by default
Allow "git repack" users to specify repacking window/depth
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....
* lt/xsha1:
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
Several <<< or === or >>> characters at the beginning of a line
is very likely to be leftover conflict markers from a failed
automerge the user resolved incorrectly, so detect them.
As usual, this can be defeated with "git commit --no-verify" if
you really do want to have those files, just like changes that
introduce trailing whitespaces.
We said "fix up by hand" after failed automerge, which was a big
"Huh? Now what?". Be a bit more explicit without being too
verbose. Suggested by Carl Worth.
I personally prefer "ignore_merges" to be on by default, because quite
often the merge diff is distracting and not interesting. That's true both
with "-p" and with "--stat" output.
If you want output from merges, you can trivially use the "-m", "-c" or
"--cc" flags to tell that you're interested in merges, which also tells
the diff generator what kind of diff to do (for --stat, any of the three
will do, of course, but they differ for plain patches or for
--patch-with-stat).
This trivial patch just removes the two lines that tells "git log" not to
ignore merges. It will still show the commit log message, of course, due
to the "always_show_header" part.

Allow "git repack" users to specify repacking window/depth
.. but don't even bother documenting it. I don't think any normal person
is supposed to ever really care, but it simplifies testing when you want
to use the "git repack" wrapper rather than forcing you to use the core
programs (which already do support the window/depth arguments, of course).
