Supposing that both the base and result sizes were both full size 64-bit
values, their encoding would occupy only 9.2 bytes each. Therefore
inflating 64 bytes is way overkill. Limit it to 20 bytes instead which
should be plenty enough for a couple years to come.

The "union delta_base" is a strange beast. It is a 20-byte
binary blob key to search a binary searchable deltas[] array,
each element of which uses it to represent its base object with
either a full 20-byte SHA-1 or an offset in the pack. Which
representation is used is determined by another field of the
deltas[] array element, obj->type, so there is no room for
confusion, as long as we make sure we compare the keys for the
same type only with appropriate length. The code compared the
full union with memcmp().
When storing the in-pack offset, the union was first cleared
before storing an unsigned long, so comparison worked fine.
On 64-bit architectures, however, the union typically is 24-byte
long; the code did not clear the remaining 4-byte alignment
padding when storing a full 20-byte SHA-1 representation. Using
memcmp() to compare the whole union was wrong.
This fixes the comparison to look at the first 20-bytes of the
union, regardless of the architecture. As long as ulong is
smaller than 20-bytes this works fine.

Jim Mayering noticed that xdiff library took insanely long time
when comparing files with many identical lines.
This was because the hash function used in the library is broken
on 64-bit architectures and caused too many collisions.

In a busy project, reverting a commit almost always results
in a conflict between one or more files (depending on the
commit being reverted). It is useful to record this
conflict in the commit-to-be message of the resulting commit
(after the resolve). The process now becomes:
git-revert <SHA-1>
<git complains and prints failed automatic>
<user manually resolves>
git-update-index <resolved files>
git-commit -s
And the commit message is now a merge of the revert commit
message and the conflict commit message, giving the user a
chance to edit it or add more information:

This reverts commit 16854571aa.
Git as recent as v1.1.6 do not understand version 3 delta.
v1.2.0 is Ok and I personally would say it is old enough, but
the improvement between version 2 and version 3 delta is not
bit enough to justify breaking older clients.
We should resurrect this later, but when we do so we shold
make it conditional.

the repository argument for git-clone should be relative to $PWD
instead of the given target directory. The old behavior gave us
surprising success and you need a few minute to know why it worked.
GIT_DIR is already exported so no need to cd into $D. And this makes
$PWD for git-fetch-pack, which is the actual command to take the given
repository dir, the same as git-clone.

apply_textdelta and send_stream can use a separate pool from the
rest of the editor interface, so we'll use a separate SVN::Pool
for them and clear the pool after each file is sent to SVN.
This drastically reduces memory usage per-changeset committed,
and makes large commits (and initial imports) of several
thousand files possible.

Once a get_commit_editor has been called from an SVN session, RA
layer operations are not allowed (well, unless you're using
file:// or http(s)://). So we'll pass an alternate SVN::Ra
object to our editor object for running 'check-path'.
This should fix commits over svnserve (svn:// without ssh, too).

When configuration variable `repack.UseDeltaBaseOffset` is set
for the repository, the command passes `--delta-base-offset`
option to `git-pack-objects`; this typically results in slightly
smaller packs, but the generated packs are incompatible with
versions of git older than (and including) v1.4.3.
We will make it default to true sometime in the future, but not

I'm using svn 1.4.0-4 in Debian unstable and apparently there's
a regression on the SVN side that prevents a symlink from
becoming a regular file (which git supports, of course).
It's not a noticeable regression for most people, but this broke
the full-svn-tests target in t/Makefile for me.
The SVN::* Perl libraries seem to have matured and improved over
the past year, and git-svn has supported them for several months
now, so with that I encourage all users to start using the
SVN::* Perl libraries with git-svn.

I was running git show on various commits found by fsck-objects
when I found this bug. Since find_unique_abbrev() cannot find
an abbreviation for an object not in the database, it will
return NULL, which is bad to run strlen() on. So instead, we'll
just display the unabbreviated sha1 that we referenced in the
commit.
I'm not sure that this is the best 'fix' for it because the
commit I was trying to show was broken, but I don't think a
program should segfault even if the user tries to do something
stupid.

Change the --verbose flag to more closely match svn. I was
somehow under the impression that --summary included --raw diff
output, but I was wrong. We now pass -r --raw --name-status as
arguments if passed -v/--verbose.
-r (recursive) is passed by default, since users usually want
it, and accepting it causes difficulty with the -r<revision>
option used by svn users. A --non-recursive switch has been
added to disable this.
Of course, --summary, --raw, -p and any other git-log options
can still be passed directly (without --name-status).
Also, several warnings about referencing undefined variables
have been fixed.
