contrib/git-svn: fix a harmless warning on rebuild (with old repos)
It's only for repositories that were imported with very early
versions of git-svn. Unfortunately, some of those repos are out
in the wild already, so fix this warning.

'svn info' doesn't work with URLs in svn <= 1.1. Now we
only run svn info in local directories.
As a side effect, this should also work better for 'init' off
directories that are no longer in the latest revision of the
repository.
svn checkout -r<revision> arguments are fixed.
Newer versions of svn (1.2.x) seem to need URL@REV as well as
-rREV to checkout a particular revision...
Add an example in the manpage of how to track directory that has
been moved since its initial revision.
A huge thanks to Yann Dirson for the bug reporting and testing
my original patch. Thanks also to Junio C Hamano for suggesting
a safer way to use git-rev-parse.

revision.c:make_parents_uninteresting() is exponential with the number
of merges in the tree. That's fine -- unless some other part of git
already has pulled the whole commit tree into memory ...
diff-delta: bound hash list length to avoid O(m*n) behavior
The diff-delta code can exhibit O(m*n) behavior with some patological
data set where most hash entries end up in the same hash bucket.
To prevent this, a limit is imposed to the number of entries that can
exist in the same hash bucket.
Because of the above the code is a tiny bit more expensive on average,
even if some small optimizations were added as well to atenuate the
overhead. But the problematic samples used to diagnoze the issue are now
orders of magnitude less expensive to process with only a slight loss in
compression.

Since I've started using the "merge.summary" flag in my repo, my merge

within merges.

This brings http-push functionality more in line with the ssh/git version,
by borrowing bits from send-pack and rev-list to process refspecs and
revision history in more standard ways. Also, the status of remote objects
is determined using PROPFIND requests for the object directory rather than
HEAD requests for each object - while it may be less efficient for small
numbers of objects, this approach is able to get the status of all remote
loose objects in a maximum of 256 requests.
The form "diff -u -U 0" shows the default 3-line contexts,
because -u and -U 0 contradicts with each other; "diff -U 0" (or
its longhand "diff --unified=0") is what we meant.
Tweak asciidoc output to work with broken docbook-xsl
docbook-xsl v1.68 incorrectly converts "<screen>" from docbook to
manpage by not rendering it verbatim. v1.69 handles it correctly, but
not many current popular distributions ship with it.
asciidoc by default converts "listingblock" to "<screen>". This change
causes asciidoc in git to convert "listingblock" to "<literallayout>", which
both old and new docbook-xsl handle correctly.
The difference can be seen in any manpage which includes a multi-line
example, such as git-branch.
[jc: the original patch was an disaster for html backends, so I made
it apply only to docbook backends. ]
This rewrites the result check code a bit. The earlier one
using awk was splitting columns at any whitespace, which
confused lines attributed incorrectly to the merge made by the
default author "A U Thor <author@example.com>" with lines
attributed to author "A".
The latest test by Ryan to add the "starting from older commit"
test is also included, with another older commit test.
Mark Wooding noticed there was a type mismatch warning in git.c; this
patch does things slightly differently (mostly tightening const) and
was what I was holding onto, waiting for the setup-revisions change
to be merged into the master branch.
Documentation/Makefile: Some `git-*.txt' files aren't manpages.
In particular, git-tools.txt isn't a manpage, and my Asciidoc gets upset
by it. The simplest fix is to Remove articles from the list of manpages

Add --temp and --stage=all options to checkout-index.
Sometimes it is convient for a Porcelain to be able to checkout all
unmerged files in all stages so that an external merge tool can be
executed by the Porcelain or the end-user. Using git-unpack-file
on each stage individually incurs a rather high penalty due to the
need to fork for each file version obtained. git-checkout-index -a
--stage=all will now do the same thing, but faster.

When amending a commit only to update the commit log message, git-status
would rightly say "Nothing to commit." Do not let this prevent commit to
be made.
I am very sorry to do this, but without this funky octopus, "git
log --no-merges master..next" will show commits already merged
into "master" forever.
There are some commits on the next branch (which is never to be
rewound) that are reverts of other commits on the next branch.
They are to revert the finer grained delta experiments that
turned out to have undesirable performance effects. Also there
are some other commits that were first done as a merge into
"next" (a pull request based on next) and then cherry picked
into master. Since they are not going to be merged into
"master" ever, they will stay forever in "log master..next".
Yuck.
So this commit records the fact that the commits currently shown
by "git log --no-merges master..next" to be merged into "master"
are already in the master, either because they really are (in
the case of git-cvsserver bits, which needed cherry-picking into
"master"), or because they are fully reverted in "next" (in the
case of finer-grained delta bits).
This shows what git thinks are missing from master. It
shows chain of commits that are already merged and chain of
commits whose net effect should amount to a no-op.
Look at each commits and make sure they are either unwanted
or already merged by cherry-picking.
(2) Record the tip of branches that I do not want. In this
case, the following were unwanted:

Commits are blocked. Naively, git-cvsserver assumes non-malicious users. Please
review the code before setting this up on an internet-accessible server.
NOTE: the <nobody> user above will need write access to the .git directory

put in an update hook to avoid this problem, so that it is maintained by
users with write access.
cvsserver: nested directory creation fixups for Eclipse clients
To create nested directories without (or before) sending file entries
is rather tricky. Most clients just work. Eclipse, however, expects
a very specific sequence of events. With this patch, cvsserver meets
those expectations.
Note: we may want to reuse prepdir() in req_update -- should move it
outside of req_co. Right now prepdir() is tied to how req_co() works.
contrib/git-svn: fix a copied-tree bug in an overzealous assertion
I thought passing --stop-on-copy to svn would save us from all
the trouble svn-arch-mirror had with directory (project) copies.
I was wrong, there was one thing I overlooked.
If a tree was moved from /foo/trunk to /bar/foo/trunk with no
other changes in r10, but the last change was done in r5, the
Last Changed Rev (from svn info) in /bar/foo/trunk will still be
r5, even though the copy in the repository didn't exist until
r10.
Now, if we ever detect that the Last Changed Rev isn't what
we're expecting, we'll run svn diff and only croak if there are
differences between them.

show-branch --topics: omit more uninteresting commits.
When inspecting contents of topic branches for yet-to-be-merged
commits, a commit that is in the release/master branch is
uninteresting. Previous round still showed them, especially,
the ones before a topic branch that was forked from the
release/master later than other topic branches.
git-mv needs to be run from the base directory so that
the check if a file is under revision also covers files

In a new repository, the initial fetch creates a master branch
if one does not exist so HEAD has something to point to.
It now creates a master at the end of the initial fetch run,
pointing to the latest revision. Previously it pointed to the
first revision imported, which is generally less useful.

contrib/git-svn: add -b/--branch switch for branch detection
I've said I don't like branches in Subversion, and I still don't.
This is a bit more flexible, though, as the argument for -b is any
arbitrary git head/tag reference.
This makes some things easier:
* Importing git history into a brand new SVN branch.
* Tracking multiple SVN branches via GIT_SVN_ID, even from multiple
repositories.
* Adding tags from SVN (still need to use GIT_SVN_ID, though).
* Even merge tracking is supported, if and only the heads end up with
100% equivalent tree objects. This is more stricter but more robust
and foolproof than parsing commit messages, imho.

If git-update-index --index-info -z is used only the first
record given to the process will actually be updated as
the -z option is ignored until after all index records
have been read and processed. This meant that multiple
null terminated records were seen as a single record which
was lacking a trailing LF, however since the first record
ended in a null the C string handling functions ignored the
trailing garbage. So --index-info should be required to be
the last command line option, much as --stdin is required
to be the last command line option. Because --index-info
implies --stdin this isn't an issue as the user shouldn't
be passing --stdin when also passing --index-info.

A recent Eclipse compat fix broke checkouts with -d. Fix it so that the server

cvsserver: checkout faster by sending files in a sensible order
Just by sending the files in an ordered fashion, clients can process them
much faster. And we can optimize our check of whether we created this
directory already -- faster.
Timings for a checkout on a commandline cvs client for a project with
~13K files totalling ~100MB:
An earlier commit 8098a178b26dc7a158d129a092a5b78da6d12b72
accidentally lost race protection from git-commit command.
This commit reinstates it. When something else updates HEAD
pointer while you were editing your commit message, the command
would notice and abort the commit.
The new flag is used to amend the tip of the current branch. Prepare
the tree object you would want to replace the latest commit as usual
(this includes the usual -i/-o and explicit paths), and the commit log
editor is seeded with the commit message from the tip of the current
branch. The commit you create replaces the current tip -- if it was a
merge, it will have the parents of the current tip as parents -- so the
current top commit is discarded.
It is a rough equivalent for:
$ git reset --soft HEAD^
$ ... do something else to come up with the right tree ...
$ git commit -c ORIG_HEAD

This adds a new flag, --topics, to help managing topic
branches. When you have topic branches forked some time ago
from your primary line of development, show-branch would show
many "uninteresting" things that happend on the primary line of
development when trying to see what are still not merged from
the topic branches.
With this flag, the first ref given to show-branch is taken as
the primary branch, and the rest are taken as the topic
branches. Output from the command is modified so that commits
only on the primary branch are not shown. In other words,
GIT-VERSION-GEN: squelch unneeded error from "cat version"
Now this is really a corner case, but if you have the git source
tree from somewhere other than the official tarball, you do not
have version file. And if git-describe does not work for you
(maybe you do not have git yet), we spilled an error message
from "cat version".
setup_revisions(): handle -n<n> and -<n> internally.
This moves the handling of max-count shorthand from the internal
implementation of "git log" to setup_revisions() so other users
of setup_revisions() can use it.
Here is an updated version of git-blame. The main changes compared to
the first version are:
* Use the new revision.h interface to do the revision walking
* Do the right thing in a lot of more cases than before. In particular
parallel development tracks are hopefully handled sanely.
* Lots of clean-up
I think git-blame is correct in this case. This patterns occur in
several other places, git-annotate seems to sometimes assign lines to
merge commits when the lines actually changed in some other commit
which precedes the merge.

contrib/git-svn: use refs/remotes/git-svn instead of git-svn-HEAD
After reading a lengthy discussion on the list, I've come to the
conclusion that creating a 'remotes' directory in refs isn't
such a bad idea.
You can still branch from it by specifying remotes/git-svn (not
needing the leading 'refs/'), and the documentation has been
updated to reflect that.
The 'git-svn' part of the ref can of course be set to whatever
you want by using the GIT_SVN_ID environment variable, as
before.
I'm using refs/remotes/git-svn, and not going with something
like refs/remotes/git-svn/HEAD as it's redundant for Subversion
where there's zero distinction between branches and directories.
Run git-svn rebuild --upgrade to upgrade your repository to use
the new head. git-svn-HEAD must be manually deleted for safety
reasons.
Side note: if you ever (and I hope you never) want to run
git-update-refs on a 'remotes/' ref, make sure you have the
'refs/' prefix as you don't want to be clobbering your
'remotes/' in $GIT_DIR (where remote URLs are stored).
