553589f782 git-svn: Make following parents atomic
find_parent_branch generates branch@rev type branches when one has to
look back through SVN history to properly get the history for a branch
copied from somewhere not already being tracked by git-svn.  If in the
process of fetching this history, git-svn is interrupted, then when one
fetches again, it will use whatever was last fetched as the parent
commit and fail to fetch any more history which it didn't get to before
being terminated.  This is especially troubling in that different
git-svn copies of the same SVN repository can end up with different
commit sha1s, incorrectly showing the history as divergent and
precluding easy collaboration using git push and fetch.

To fix this, when we initialise the Git::SVN object $gs to search for
and perhaps fetch history, we check if there are any commits in SVN in
the range between the current revision $gs is at, and the top revision
for which we were asked to fill history.  If there are commits we're
missing in that range, we continue the fetch from the current revision
to the top, properly getting all history before using it as the parent
for the branch we're trying to create.

f69e836fab Fix tests breaking when checkout path contains shell metacharacters
This fixes the remainder of the issues where the test script itself is at
fault for failing when the git checkout path contains whitespace or other
shell metacharacters.

The majority of git svn tests used the idiom

  test_expect_success "title" "test script using $svnrepo"

These were changed to have the test script in single-quotes:

  test_expect_success "title" 'test script using "$svnrepo"'

which unfortunately makes the patch appear larger than it really is.

One consequence of this change is that in the verbose test output the
value of $svnrepo (and in some cases other variables, too) is no
longer expanded, i.e. previously we saw

  * expecting success:
	test script using /path/to/git/t/trash/svnrepo

but now it is:

  * expecting success:
	test script using "$svnrepo"

ffab62681c git-svn: handle changed svn command-line syntax
Previously, if you passed a revision and a path to svn cp, it meant to look
back at that revision and select that path.  New behaviour is to get the
path then go back to the revision (like other commands that accept @REV
or -rREV do).  The more consistent syntax is not supported by the old
tools, so we have to try both in turn.

4a1bb4c3f8 git-svn: don't attempt to minimize URLs by default
For tracking branches and tags, git-svn prefers to connect
to the root of the repository or at least the level that
houses branches and tags as well as trunk.  However, users
that are accustomed to tracking a single directory have
no use for this feature.

As pointed out by Junio, users may not have permissions to
connect to connect to a higher-level path in the repository.

While the current minimize_url() function detects lack of
permissions to certain paths _after_ successful logins, it
cannot effectively determine if it is trying to access a
login-only portion of a repo when the user expects to
connect to a part where anonymous access is allowed.

For people used to the git-svnimport switches of
--trunk, --tags, --branches, they'll already pass the
repository root (or root+subdirectory), so minimize URL
isn't of too much use to them, either.

For people *not* used to git-svnimport, git-svn also
supports:

 git svn init --minimize-url \
  --trunk http://repository-root/foo/trunk \
  --branches http://repository-root/foo/branches \
  --tags http://repository-root/foo/tags

And this is where the new --minimize-url command-line switch
comes in to allow for this behavior to continue working.

ccb6b6f5b5 t910*: s/repo-config/config/g; poke around possible race conditions
Some of the repo-config => config renaming missed the git-svn
tests; so I'm just renaming them to be consisten with the
rest of the modern git.

Also, some of the newer tests didn't have 'poke' in them
to workaround race conditions on fast machines.  This adds
places where they can _possibly_ occur; but I don't have
fast enough hardware to trigger them.

b9dffd8cad git-svn: --follow-parent tracks multi-parent paths
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).

Add a test for this, too, of course.

d8115c5104 git-svn: don't write to the config file from --follow-parent

8a603774de git-svn: fix several fetch bugs related to repeated invocations
We no longer delete the top-level directory even if it got
deleted from the upstream repository.  In gs_do_update; we
double-check that the path we're tracking exists at both
endpoints before proceeding.  We have also added additional
protection against fetching revisions out-of-order.

To simplify our internal interfaces, I've disabled passing the
'recursive' flag to the gs_do_{switch,update} wrapper functions
since we always want it in git-svn.  We also pass the
entire Git::SVN object rather than just the path because it
helped me debug.

When printing progress, the refname is printed out to make
it less confusing when multi-fetch is running.

ce2a0f2f9d git-svn: stop using path names as refnames with --follow-parent
Using path names as refnames breaks horribly if a user is
tracking one large, toplevel directory, and a lower-level
directory is followed from another project is a parent
of another ref, as it will cause refnames such as:
'refs/remotes/trunk/path/to/stuff', which will conflict
with a refname of 'refs/remotes/trunk'.

Now we just append @$revno to the end of it the current
refname.  And if we have followed back to a grandparent, then
we'll strip any existing '@$parent_revno' strings before
appending our own '@$revno' string to it.

2b27f6c884 git-svn: correctly handle do_{switch,update} in deep directories
The do_update or do_switch functions in SVN only allow for a
single path component; so 'path/to/deep/dir' would be
interpreted as 'path'.

SVN 1.4.x has a reparent function that can let us change the
session to use a higher-level root of the repository, so we can
use that for do_switch (which still doesn't seem to work in SVN
1.4.3 (a fix was attempted, but they missed the rest of the
typemap changes needed in trunk...)).

On the do_update side, we can use set_path on higher level
directories and set them to a newer revision so they don't get
updated.  We can't do this with do_switch, either, because the
relative path we're tracking can change (directory moving into
a child of itself).

Because of these changes, we need to double check that our Fetch
editor is correctly performing stripping on any prefixed paths
from update, otherwise we'll just die() because that would be
a bug.

Added a test case which helped me notice and fix problems with
do_switch, too.

3ebe8df7f6 git-svn: fix segfaults from accessing svn_log_changed_path_t
svn_log_changed_path_t structs were being used out of scope
outside of svn_ra_get_log (because I wanted to eventually be
able to use git-svn with only a single connection to the
repository).  So now we dup them into a hash.

This was fixed while making --follow-parent fetches more
efficient.  I've moved parsing of the command-line --revision
argument outside of the Git::SVN module so Git::SVN::fetch() can
be used in more places (such as find_parent_branch).

e5a0b240fc git-svn: correctly track revisions made to deleted branches
git-svn has never been able to handle deleted branches very well
because svn_ra_get_log() is all-or-nothing, meaning that if the
max revision passed to it does not contain the path we're
tracking, we miss all the revisions in the repository.

Branches fetched using --follow-parent still do this
sub-optimally (will be fixed soon).  --follow-parent will soon
become the default, so we will assume that when using get_log();

We will also avoid tracking revprops for revisions with no
path-related changes since otherwise we just end up pulling
logs to paths we don't care about.

Also added a test for this to t9104-git-svn-follow-parent.sh and
correctly commit the log message in the preceeding test (which
conflicted with a filename).

7f578c55af git-svn: --follow-parent now works on sub-directories of larger branches
This means that tracking the path of:

  /another-larger/trunk/thunk/bump/thud inside a repository

would follow:

  /larger-parent/trunk/thunk/bump/thud

even if the svn log output looks like this:
  --------------------------------------------
  Changed paths:
     A /another-larger (from /larger-parent:5)
  --------------------------------------------

Note: the usage of get_log() in git-svn still makes a
an assumption that shouldn't be made with regard to
revisions existing for a particular path.

7b3fab877d Work around Subversion race in git-svn tests.
Some of the git-svn tests can fail on fast machines due to a race in
Subversion: if a file is modified in the same second it was checked out
(or in for that matter), Subversion will not consider it modified. This
works around the problem by increasing the timestamp by one second
before each commit.

e66191f483 git-svn: fix tests to work with older svn
Some of the recent changes and shortcuts to the tests broke
things for people using older versions of svn:

t9104-git-svn-follow-parent.sh:
  v1.2.3 (from SuSE 10.0 as reported by riddochc on #git
  (thanks!)) required an extra 'svn up'.  I was also able to
  reproduce this with v1.1.4 (Debian Sarge).

lib-git-svn.sh:
  SVN::Repos bindings in versions up to and including 1.1.4
  (Sarge again) do not pass fs-config options to the underlying
  library.  BerkeleyDB repositories also seem completely broken
  on all my Sarge machines; so not using FSFS does not seem to
  be an option for most people.
