When using do_switch:
We only need to ensure the index is clean and set to that of the
parent tree) we rely on being able to reconstruct full files
with deltas transferred over the network.
When using do_update:
We may safely unlink the index if we are fetching an entire
new tree with do_update. Having an old index (from a
previously deleted/abandoned directory) around can cause
irrelevant files to be mistakenly kept.

Clearing the pool of the previous SVN::Ra connection we have
seems to to fix mysterious connection dropping errors when
reconnecting to different paths of svn:// repositories hosted by
rubyforge.org.
Note: I'm not sure *why* this fixes things things,
but it does for me.

Several bugs caused this to fail:
* GIT_DIR was set incorrectly after entering the target directory
* Avoid double chdir-ing when clone is called with an explicit path
* create target subdirectory *before* running git-init when using
the multi-init path

If we are run inside a subdirectory of a working tree, we'll
chdir to the top first before touching anything. This also
prevents the accidental creation of .git directories inside
subdirectories since they need metadata.

This allows the user to run git-svn show-ignore on there
current HEAD without needing to remember which branch/ref they
branched from with -i. Also, find_by_url should correctly
handle cases where the URL passed to it is not valid.

Since the options that affect the way metadata is handled in
git-svn, should be consistently set/unset throughout history
imported by git-svn; it makes sense to allow the user to set
certain options from the command-line that will write to the
config file when initially creating the repository.
Also, fix some formatting issues while we're updating
documentation.

svm:mirror is not useful at all for us. Parts of the old unit
test were broken and based on my misunderstanding of the
svm:mirror property.
When we read svm:source; make sure we correctly handle the '!'
in it: it is used to separate the path of the repository root
from the virtual path within the repository. We don't need
to make that distinction, honestly!
We also ensure that subdirectories are also mirrored with the
correct URL if we're using useSvmProps.
We have a new test that uses dumped repo that was really
created using SVN::Mirror to avoid ambiguities and
mis-understandings about the svm: properties.
Note: trailing whitespace in the svm.dump file is unfortunately
a reality and required by SVN; so please ignore it when applying
this patch.
Also, ensure that the -R/--remote/--svn-remote flag is always
in effect if explicitly passed via the command-line. This
allows us to track logically different mirrors sharing the
same URL (probably common with SVN::Mirror/SVK users).

This is similar to useSvmProps, but far simpler in

This feature allows users to create repositories from alternate
URLs. For example, an administrator could run git-svn on the
server locally (accessing via file://) but wish to distribute
the repository with a public http:// or svn:// URL in the
metadata so users of it will see the public URL.

Having it named as 'config' prevents us from tracking a
ref named 'config', which is a huge mistake.
On the non-technical side, the word 'config' implies that
a user can freely modify it; but that's not the case

This works similarly to 'svn update' or 'git pull' except that
it preserves linear history with 'git rebase' instead of 'git
merge' for ease of dcommit-ing with git-svn.
While we're at it, put the working_head_info() logic
into its own function and allow --fetch-all/--all for
dcommit and rebase (which will fetch all refs in the
current [svn-remote] instead of just the working one).
Note that the '-a' switch (short for --fetch-all/--all) has been
removed as it conflicts with the non-svn 'git fetch'

On newly-created repositories, 'refs/heads/master' does not
point to anything. This can be confusing to new users; so we
update 'master' to point to the last imported ref after fetching
is done.
Once 'master' is valid; we assume HEAD points to it; and if
the repository is not bare, then checkout the files if the
working tree is clean and unused.

This allows users to use SVM (SVN::Mirror) to mirror a remote
repository to use dcommit to commit to the repository that SVM
was mirroring. When dcommit is used in this manner, the automatic
fetch + rebase/reset does not happen; in which case the user will
have to manually invoke svm/svk, run 'git svn fetch', and finally
'git rebase'.

multi-init is now just an alias that requires -T/-t/-b;

multi-fetch is deprecated, "fetch -a" is easier to type
By default, fetch will fetch everything from its default
[svn-remote]; if fetch [--all|-a] is specified, then it will
fetch from all svn remotes. Refspecs on the command-line
(like git-fetch) are not supported.
Also, enable -r/--revision arguments for fetch so
users can shoot themselves in the foot^W^W^W^W^W
skip some history and do the equivalent of a shallow
clone/fetch they're not interested in.

Similar in spirit to the recent dcommit change, we now
look at 'HEAD' by default to look for a GIT_SVN_ID
so the user won't have to pass -i <GIT_SVN_ID> argument.
We are also more tolerant of of people passing bare remote names
as a result (just $GIT_SVN_ID without the -i)

* dcommit no longer requires the correct -i/GIT_SVN_ID option
passed to it. Since you're committing from HEAD (or another
commit that is a parent of HEAD), you'll be able to find
a commit with metadata information containing the SVN URL
that your HEAD was descended from anyways.
* I don't think dcommit ever worked for people using the
noMetadata option; so I don't think relying on metadata
is an issue.
* useSvmProps users shouldn't commit to SVN::Mirror created
repositories anyways, right?
* Users of globbing should automatically be able to commit
to paths that are not explicitly set in .git/config

multi-init did not write a svn-remote.<remote>.url config
entry without a --trunk argument.
Also, The svm:mirror property is used by SVN::Mirror to track
the path of the repository that we are mirroring. We need to
append that to the source (which is (presumably) just the URL of
the repository root).
Lastly, we now look harder for svm:(source|mirror|uuid) properties
in sub and parent directories. Since our relative path could
be tweaked.

We need a separate .rev_db file for each repository we're
tracking. This allows us to track the same logical path off
multiple mirrors. We preserve a symlink to the old .rev_db
(no-UUID) if we're (auto-)migrating from an old version to
preserve backwards compatibility.
Also, get rid of the uuid() wrapper since we cache UUID in our
private config, and the SVN::Ra::get_uuid() function memoizes
the return value per-connection.

Make sure we flush our userspace buffers and and fsync(2)
.rev_db information to disk if we use these options because
we really don't want to lose this information.
Also, disallow --use-svm-props and --no-metadata from the
command-line because history will be inconsistent if they're
only used occasionally. If a user wants to use these options,
they must be set in the config so they're always on.

Available options are currently:
svn-remote.<remote>.{noMetadata,useSvmProps,followParent}
These boolean switches will override options set globally in
[svn], and even override options set on the command-line (this
should probably change in the future, however).
Note that the noMetadata and useSvmProps options conflict. It's
both technically and logically impossible to use them together.

Several bugs were found and fixed while getting this to work:
* Remember the 'R'(eplace) case of actions and treat it like we
would an 'A'(dd) case.
* Fix a small case of follow-parent missing a parent if a
subdirectory was modified in the revision where the parent was
copied.
* dirents returned by get_dir sometimes expire if the data
structure is too big and the pool is destroyed, so we
cache get_dir (along with check_path and get_revprops)
temporarily along with its pool.

I incorrectly used $path/? and $path/* to strip off leading
directories, but places where $path = 'branches/0.17' would
incorrectly strip changes to 'branches/0.17.1' as well.
For globs, we require that our '*' is its own path component
(surrounded by '/' or nothing). Enforce this when --prefix= is
passed to us, too.

We don't need them anymore, all the rough points of

The only improvement in the future will probably be
--follow-parent-harder, which will track subdirectories and
follow individual file history (so annotate/blame can be
complete); but that is still a ways off.

These checks were needed before git-svn got smarter about
match_paths() and using path information returned by get_log().
We also have extra checking against fetching revisions
out-of-order these days; so we don't have to worry about that as
much. We also check for tree deletions in match_paths() and
skip those as well.

We can have a branch that was deleted, then re-added under the
same name but copied from another path, in which case we'll have
multiple parents (we don't want to break the original ref, nor
lose copypath info).

This is similar to the way git proper handles refs, except we
use the keys 'branches' and 'tags' to distinguish when we want
to use wildcards.
The left-hand side of the ':' contains the remote path, and must
have one asterisk ('*') in it for the branch name. The asterisk
may be in any component of the path as long as is it on its own
directory level.
The right-hand side contains the refname and must have the
asterisk as the last path component.
branches = branches/*:refs/remotes/*
tags = tags/*:refs/remotes/tags/*
