git-read-tree: fix "--reset" handling
Update tutorial a bit for scripted helpers.
Trivial git script fixups
Fix permissions, and add trivial "reset" and "add" scripts.
The "reset" script just resets the index back to head, while the "add"
script is just a crutch for people used to do "cvs add".

then allow you to use arguments like "v2.6.12-rc5.." or similar
human-readable ranges.
It's really quite stupid: "a..b" will be converted into "a" and "^b" if
"a" and "b" are valid object pointers. And the "--default" case will be
used if nothing but flags have been seen, so that you can default to a
certain argument if there are no other ranges.

[PATCH] read-tree: fix too strong index requirement #5ALT
This fixes too strong index requirement 3-way merge enforces in
one case: the same file is added in both branches.
In this case, the original code insisted that if the index file
has that path, it must match our branch and be up-to-date.
However in this particular case, it only has to match it, and
can be dirty. We just need to make sure that we keep the
work-tree copy instead of checking out the merge result.
The resolution of such a path, however, cannot be left to
outside script, because we will not keep the original stage0
entries for unmerged paths when read-tree finishes, and at that
point, the knowledge of "if we resolve it to match the new file
added in both branches, the merge succeeds and the work tree
would not lose information, but we should _not_ update the work
tree from the resulting index file" is lost. For this reason,
the now code needs to resolve this case (#5ALT) internally.
This affects some existing tests in the test suite, but all in
positive ways. In t1000 (3-way test), this #5ALT case now gets
one stage0 entry, instead of an identical stage2 and stage3
entry pair, for such a path, and one test that checked for merge
failure (because the test assumed the "stricter-than-necessary"
behaviour) does not have to fail anymore. In t1005 (emu23
test), two tests that involves a case where the work tree
already had a change introduced in the upstream (aka "merged
head"), the merge succeeds instead of failing.

[PATCH] read-tree --emu23.
This new flag causes two-way fast forward to internally use the
three-way merge mechanism. This behaviour is intended to offer
a better fast forward semantics when used in a dirty work tree.
The new test t1005 is parallel to the existing t1001 "pure
2-way" tests, but some parts that are commented out would fail.
These failures are due to three-way merge enforcing too strict
index requirements for cases that could succeed. This problem
will be addressed by later patches.
Without even changing three-way mechanism, the --emu23 two-way
fast forward already gives the user an easier-to-handle merge
result when a file that "merged head" updates has local
modifications. This is demonstrated as "case 16" test in t1005.

This is a halfway between debugging aid and a helper to write an

consists of a list of "status" letters, and limits the diff

- A broken pair (aka "complete rewrite"), does not match D
(deleted) or N (created). Use B to look for them.
- The letter "A" in the diff-filter string does not match
anything itself, but causes the entire diff that contains
selected patches to be output (this behaviour is similar to
that of --pickaxe-all for the -S option).
For example,
$ git-rev-list HEAD |

[PATCH] Tidy up some rev-list-related stuff
This patch tidies up the git-rev-list documentation and epoch.c, which
are in severe clash with the unwritten coding style now, and quite
unreadable.
It also fixes up compile failures with older compilers due to variable
declarations after code.
The patch mostly wraps lines before or on the 80th column, removes
plenty of superfluous empty lines and changes comments from // to /* */.

Leave merge failures in the filesystem
This changes how we handle merges: if a automated merge
fails, we will leave the index as a clean entry pointing
to the original branch, and leave the actual file _dirty_
the way the "merge" program left it.
You can then just do "git-diff-files -p" to see what the
merge conflicts did, fix them up, and commit the end result.
NOTE NOTE NOTE! Do _not_ use "git commit" to commit such
a merge. It won't set the parents right. I'll need to fix
that. In the meantime, you'd need to merge using
git-commit-tree $(git-write) -p HEAD -p MERGE_HEAD
or something like that by hand.

[PATCH] three --merge-order bug fixes
This patch fixes three bugs in --merge-order support
* mark_ancestors_uninteresting was unnecessarily exponential which
caused a problem when a commit with no parents was merged near the
head of something like the linux kernel
* removed a spurious statement from find_base which wasn't
apparently causing problems now, but wasn't correct either.
* removed an unnecessarily strict check from find_base_for_list
that causes a problem if git-rev-list commit ^parent-of-commit
is specified.
* added some unit tests which were accidentally omitted from
original merge-order patch
The fix to mark_ancestors_uninteresting isn't an optimal fix - a full
graph scan will still be performed in this case even though it is
not strictly required. However, a full graph scan is linear
and still no worse than git-rev-list HEAD which runs in less than 2
seconds on a warm cache.

This patch linearises the GIT commit history graph into merge order

The linearisation produced by this patch is superior in an objective sense
to that produced by the existing git-rev-list implementation in that
the linearisation produced is guaranteed to have the minimum number of
discontinuities, where a discontinuity is defined as an adjacent pair of
commits in the output list which are not related in a direct child-parent
relationship.

A test script, t/t6000-rev-list.sh, includes a test which demonstrates
that the linearisation produced by --merge-order has less discontinuities
than the linearisation produced by git-rev-list without the --merge-order
flag specified. To see this, do the following:
cd t
./t6000-rev-list.sh

cat actual-default-order

The existing behaviour of git-rev-list is preserved, by default. To obtain
the modified behaviour, specify --merge-order or --merge-order --show-breaks

repository and has reasonable performance on both - ~50-100% slower than the original algorithm.

Add a "-u" flag to update the tree as a result of a merge.
Right now this code is way too anal about things, and fails merges it
shouldn't, but let me fix up the different cases and this will allow for
much smoother merging even in the presense of dirty data in the working
tree.
Make fiel checkout function available to the git library
The merge stuff will want it soon, and we don't want to
duplicate all the work..

git-read-tree: fix up three-way merge tests
When we collapse three entries, we need to check all of the
collapsed entries against the old pre-merge state.

git-read-tree: be a lot more careful about merging dirty trees
We don't want to overwrite state that we haven't committed yet
when merging, so it's better to make git-read-tree fail than
end up with a merge tree that ends up not having the dirty changes.
Update git-resolve-script to fail cleanly when git-read-tree fails.

[PATCH] Make git-update-cache --force-remove regular
Make the --force-remove flag behave same as --add, --remove and
--replace. This means I can do
git-update-cache --force-remove -- file1.c file2.c
which is probably saner and also makes it easier to use in cg-rm.

[PATCH] rename git-rpush and git-rpull to git-ssh-push and git-ssh-pull
In preparation for 1.0 release, this makes the command names
consistent with others in git-*-pull family.

diff 'rename' format change.
Clearly even Junio felt git "rename" header lines should say "from/to"
instead of "old/new", since he wrote the documentation that way.
This way it also matches "copy".
git-apply will accept both versions, at least for a while.

git-apply: consider it an error to apply no changes
A "--stat" or a "--check" will just be quiet, but if
you try to apply something with no changes, that's an
error.

[PATCH] Documentation: describe diff tweaking.
This adds documentation for the diffcore mechanism and explains
how numeric parameters to -B/-C/-M options affect the output,
which was left "black magic" so far.
The documentation is not connected to any of the other asciidoc
nodes yet. Awaiting for suggestions, fixes and help from other
people.

git-apply: fix rename header parsing
It's not "rename from" and "rename to", it's "rename old" and "rename new".
Which is illogical and doesn't match the "copy from/to" case, but that's
life. Maybe Junio will fix it up one of these days.

[PATCH] pull: gracefully recover from delta retrieval failure.
This addresses a concern raised by Jason McMullan in the mailing
list discussion. After retrieving and storing a potentially
deltified object, pull logic tries to check and fulfil its delta
dependency. When the pull procedure is killed at this point,
however, there was no easy way to recover by re-running pull,
since next run would have found that we already have that
deltified object and happily reported success, without really
checking its delta dependency is satisfied.
This patch introduces --recover option to git-*-pull family
which causes them to re-validate dependency of deltified objects
we are fetching. A new test t5100-delta-pull.sh covers such a
failure mode.
