0bed5eaa0e git-svn: enable follow-parent functionality by default
--no-follow-parent disables and reverts it back to the old
default behavior of not following parents (if you don't care for
full history).

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
Having 'fetch' entries in the config file created from

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.

706587fc6d git-svn: add support for metadata in .git/config
Of course, we handle metadata migrations from previous versions
and we have added unit tests.

The new .git/config remotes resemble non-SVN remotes.  Below
is an example with comments:

[svn-remote "git-svn"]
	; like non-svn remotes, we have one URL per-remote
	url = http://foo.bar.org/svn

	; 'fetch' keys are done in the same way as non-svn
	; remotes, too.  With the left-hand-side of the ':'
	; being the remote (SVN) repository path relative to the
	; above 'url' key; and the right-hand-side being a
	; remote ref in git (refs/remotes/*).
	; An empty left-hand-side means that it will fetch
	; the entire contents of the 'url' key.
	; old-style (migrated from previous versions of git-svn)
	; are like this:
	fetch = :refs/remotes/git-svn

	; this is created by a current version of git-svn
	; using the multi-init command with an explicit
	; url (specified above).  This allows multi-init
	; to reuse SVN::Ra connections.
	fetch = trunk:refs/remotes/trunk
	fetch = branches/a:refs/remotes/a
	fetch = branches/b:refs/remotes/b
	fetch = tags/0.1:refs/remotes/tags/0.1
	fetch = tags/0.2:refs/remotes/tags/0.2
	fetch = tags/0.3:refs/remotes/tags/0.3

[svn-remote "alt"]
	; this is another old-style remote migrated over
	; to the new config format
	url = http://foo.bar.org/alt

3e8a5db966 git-apply: guess correct -p<n> value for non-git patches.
This enhances the third point in the previous commit.  When
applying a non-git patch that begins like this:

	--- 2.6.orig/mm/slab.c
	+++ 2.6/mm/slab.c
	@@ -N,M +L,K @@@
	...

and if you are in 'mm' subdirectory, we notice that -p2 is the
right option to use to apply the patch in file slab.c in the
current directory (i.e. mm/slab.c)

The guess function also knows about this pattern, where you
would need to use -p0 if applying from the top-level:

	--- mm/slab.c
	+++ mm/slab.c
	@@ -N,M +L,K @@@
	...

9987d7c58a git-apply: notice "diff --git" patch again
Earlier one that tried to be too consistent with GNU patch by
not stripping the leading path when we _know_ we are in a
subdirectory and the patch is relative to the toplevel was a
mistake.  This fixes it.

 - No change to behaviour when it is run from the toplevel of
   the repository.

 - When run from a subdirectory to apply a git-generated patch,
   it uses the right -p<n> value automatically, with or without
   --index nor --cached option.

 - When run from a subdirectory to apply a randomly generated
   patch, it wants the right -p<n> value to be given by the
   user.

The second one is a pure improvement to correct inconsistency
between --index and non --index case, compared with 1.5.0.  The
third point could be further improved to guess what the right
value for -p<n> should be by looking at the patch, but should be
a topic of a separate patch.

56185f49d0 git-apply: require -p<n> when working in a subdirectory.
git-apply running inside a subdirectory, with or without --index,
used to always assume that the patch is formatted in such a way
to apply with -p1 from the toplevel, but it is more useful and
consistent with the use of "GNU patch -p1" if it defaulted to
assume that its input is meant to apply at the level it is
invoked in.

This changes the behaviour.  It used to be that the patch
generated this way would apply without any trick:

	edit Documentation/Makefile
	git diff >patch.file
	cd Documentation
	git apply ../patch.file

You need to give an explicit -p2 to git-apply now.  On the other
hand, if you got a patch from somebody else who did not follow
"patch is to apply from the top with -p1" convention, the input
patch would start with:

	diff -u Makefile.old Makefile
	--- Makefile.old
	+++ Makefile

and in such a case, you can apply it with:

	git apply -p0 patch.file

The bug probably meant that 'git apply', not moving up to the

ea5e370aa9 fast-import: Support reusing 'from' and brown paper bag fix reset.
It was suggested on the mailing list that being able to use `from`
in any commit to reset the current branch is useful in some types of
importers, such as a darcs importer.

We originally did not permit resetting an existing branch with a
new `from` command during a `commit` command, but this restriction
was only to help debug the hacked up cvs2svn that Jon Smirl was
developing in parallel with git-fast-import.  It is probably more
of a problem to disallow it than to allow it.  So now we permit a
`from` during any `commit`.

While making the changes required to permit multiple `from`
commands on the same branch, I discovered we no longer needed the
last_commit field to be set to 0 during a reset, so that was removed.
(Reset was originally setting the field to 0 to signal cmd_from()
that it was OK to execute on the branch.)

While poking around in this section of fast-import I also realized
the `reset` command was not working as intended if the corresponding
`from` command was omitted (as allowed by the BNF grammar and the
code).  If `from` was omitted we cleared out the tree but we left
the tree SHA-1 and parent commit SHA-1 intact.  This is not what
the user intended in this case.  Instead they would be trying to
reset the branch to have no parent and to have no tree, making the
branch look new-born during the next commit.  We now clear these
SHA-1 values during `reset`, ensuring the branch looks new-born if
`from` does not get supplied.

New test cases for these were also added.

Most users don't need the pack boundary information that fast-import

Those users who do want this information probably want it captured

So dumping the boundary commits to a log file makes more sense then
printing them to standard output.

563b43ee45 Avoid ActiveState Perl IO in t800[12]
Use sed instead, it comes with cygwin and there is almost no chance of
someone installing a sed with default CRLF lineendings by accident.

825769a8fe Teach fast-import how to clear the internal branch content.
Some frontends may not be able to (easily) keep track of which files
are included in the branch, and which aren't.  Performing this
tracking can be tedious and error prone for the frontend to do,
especially if its foreign data source cannot supply the changed
path list on a per-commit basis.

fast-import now allows a frontend to request that a branch's tree
be wiped clean (reset to the empty tree) at the start of a commit,
allowing the frontend to feed in all paths which belong on the branch.

This is ideal for a tar-file importer frontend, for example, as
the frontend just needs to reformat the tar data stream into a gfi
data stream, which may be something a few Perl regexps can take
care of. :)

7073e69e38 Don't do non-fastforward updates in fast-import.
If fast-import is being used to update an existing branch of
a repository, the user may not want to lose commits if another
process updates the same ref at the same time.  For example, the
user might be using fast-import to make just one or two commits
against a live branch.

We now perform a fast-forward check during the ref updating process.
If updating a branch would cause commits in that branch to be lost,
we skip over it and display the new SHA1 to standard error.

This new default behavior can be overridden with `--force`, like
git-push and git-fetch.
