fd499bcc9d git-svn: use "no warnings 'once'" to disable false-positives
Some variables coming from the Subversion's Perl bindings are used
in our code only once, so the interpreter warns us about it.  These
warnings are false-positives, because the variables themselves are
initialized in the binding's guts, that are made by SWIG.

Credits to Sam Vilain for his note about "no warnings 'once'".

9ff74e95da Don't checkout the full tree if avoidable
In most cases of branching, the tree is copied unmodified from the trunk
to the branch.  When that is done, we can simply start with the parent's
index and apply the changes on the branch as usual.

[ew: rewritten from Steven's original to use SVN::Client instead
     of the command-line svn client.

     Since SVN::Client connects separately, we'll share our
     authentication providers array between our usages of
     SVN::Client and SVN::Ra, too.  Bypassing the high-level
     SVN::Client library can avoid this, but the code will be
     much more complex.  Regardless, any implementation of this
     seems to require restarting a connection to the remote
     server.

     Also of note is that SVN 1.4 and later allows a more
     efficient diff_summary to be done instead of a full diff,
     but since this code is only to support SVN < 1.4.4, we'll
     ignore it for now.]

a51cdb0c04 git-svn: fix "Malformed network data" with svn:// servers
We have a workaround for the reparent function not working
correctly on the SVN native protocol servers.  This workaround
opens a new connection (SVN::Ra object) to the new
URL/directory.

Since libsvn appears limited to only supporting one connection
at a time, this workaround invalidates the Git::SVN::Ra object
that is $self inside gs_fetch_loop_common().  So we need to
restart that connection once all the fetching is done for each
loop iteration to be able to run get_log() successfully.

4dbfe2e9bd git-svn: always use --first-parent
This makes git-svn unconditionally invoke git-log with --first-parent when
it is trying to discover its upstream subversion branch and collecting the
commit ids which should be pushed to it with dcommit. The reason for always
using --first-parent is to make git-svn behave in a predictable way when the
ancestry chain contains merges with other git-svn branches.

Since git-svn now always uses 'git-log --first-parent' there is no longer
any need for the --first-parent option to git-svn, so this is removed.

05b4df3153 git-svn: add support for --first-parent
When git-svn uses git-log to find embedded 'git-svn-id'-lines in commit
messages, it can get confused when local history contains merges with
other git-svn branches. But if --first-parent is supplied to git-log,
working_head_info() will only see 'branch-local' commits and thus the
first commit containing a 'git-svn-id' line should refer to the correct
subversion branch.

751eb39590 git-svn: fix dcommit clobbering upstream when committing multiple changes
Although dcommit could detect if the first commit in the series
would conflict with the HEAD revision in SVN, it could not
detect conflicts in further commits it made.

Now we rebase each uncommitted change after each revision is
committed to SVN to ensure that we are up-to-date.  git-rebase
will bail out on conflict errors if our next change cannot be
applied and committed to SVN cleanly, preventing accidental
clobbering of changes on the SVN-side.

--no-rebase users will have trouble with this, and are thus
warned if they are committing more than one commit.  Fixing this
for (hopefully uncommon) --no-rebase users would be more complex
and will probably happen at a later date.

Thanks to David Watson for finding this and the original test.

29633bb91c git-svn: fix commiting renames over DAV with funky file names
Renaming files with non-URI friendly characters caused
breakage when committing to DAV repositories (over http(s)).

Even if I try leaving out the $self->{url} from the return value
of url_path(), a partial (without host), unescaped path name
does not work.

Filenames for DAV repos need to be URI-encoded before being
passed to the library.  Since this bug did not affect file://
and svn:// repos, the git-svn test library needed to be expanded
to include support for starting Apache with mod_dav_svn enabled.

This new test is not enabled by default, but can be enabled by
setting SVN_HTTPD_PORT to any available TCP/IP port on
127.0.0.1.

Additionally, for running this test, the following variables
(with defaults shown) can be changed for the suitable system.
The default values are set for Debian systems:

  SVN_HTTPD_MODULE_PATH=/usr/lib/apache2/modules
  SVN_HTTPD_PATH=/usr/sbin/apache2

7730fbe624 git-svn: fix blocking with svn:// servers after do_switch
We now explicitly disconnect before starting new SVN::Ra
connections.  SVN::Ra objects will automatically be disconnected
from the server on DESTROY.

SVN servers seem to have problems accepting multiple connections
from one client, and the SVN library has trouble being connected
to multiple servers at once.  This appears to cause opening the
second connection to block, and cause git-svn to be unusable
after using the do_switch() function.

git-svn opens another connection because a workaround is
necesary for the buggy reparent function handling on certain
versions of svn:// and svn+ssh:// servers.  Instead of using the
reparent function (analogous to chdir), it will reopen a new
connection to a different URL on the SVN server.

dc431666d3 git-svn: don't minimize-url when doing an init that tracks multiple paths
I didn't have a chance to test the off-by-default minimize-url
stuff enough before, but it's quite broken for people passing
the --trunk/-T, --tags/-t, --branches/-b switches to "init" or
"clone" commands.

Additionally, follow-parent functionality seems broken when we're
not connected to the root of the repository.

Default behavior for "traditional" git-svn users who only track
one directory (without needing follow-parent) should be
reasonable, as those users started using things before
minimize-url functionality existed.

Behavior for users more used to the git-svnimport-like command
line will also benefit from a more-flexible command-line than
svnimport given the assumption they're working with
non-restrictive read permissions on the repository.

I hope to properly fix these bugs when I get a chance to in the
next week or so, but I would like to get this stopgap measure of
reverting to the old behavior as soon as possible.

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.

0dc03d6a30 git-svn: clean up caching of SVN::Ra functions
This patch was originally intended to make the Perl GC more
sensitive to the SVN::Pool objects and not accidentally clean
them up when they shouldn't be (causing segfaults).  That didn't
work, but this patch makes the code a bit cleaner regardless

Put our caches for get_dir and check_path calls directly into
the SVN::Ra object so they auto-expire when it is destroyed.

dirents returned by get_dir() no longer needs the pool object
stored persistently along with the cache data, as they'll be
converted to native Perl hash references.

Since calling rev_proplist repeatedly per-revision is no longer
needed in git-svn, we do not cache calls to it.

After reading the leading contents from a symlink data obtained

slurped more than we asked for in stdio buffer, and the child

befc9adc0c git-svn: fix useSvmProps, hopefully for the last time
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).

d4eff2bda5 git-svn: make (multi-)fetch safer but slower
get_log with explicit paths is the safest way to get revisions
that change a particular path we're interested in.
Unfortunately that means we still have to run get_log multiple
times for each path we're interested in, and even more if
a path gets deleted.

The first argument of get_log() is an array reference, but we
shouldn't use more than one element in that array ref because
the non-existence of _one_ of those paths for a particular range
would cause an error for all paths in that range, so yes, we
need multiple get_log calls to be on the safe side...

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.

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
