7ffa35b047 git-svn: use SVN::Ra::get_dir2 when possible
This avoids the following failure with normal "get_dir" on newer
versions of SVN (tested with SVN 1.8.8-1ubuntu3.1):

  Incorrect parameters given: Could not convert '%ld' into a number

get_dir2 also has the potential to be more efficient by requesting
less data.

835e3ddeff git-svn: prepare SVN::Ra config pieces once
Memoizing these initialization functions saves some memory for
long fetches which require scanning many unwanted revisions
before any wanted revisions happen.

aee7d04c12 git-svn: save a little memory as fetch progresses
There is no reason to keep entries in the %revs hash after we're
done processing a revision, so allow entries become freed as
processing continues.

6725ecaba7 git-svn: remove unnecessary DESTROY override
This override was probably never necessary, but most likely a no-op
as it does not appear to do anything in SVN::Ra itself.

dfa72fdb96 git-svn: reload RA every log-window-size
Despite attempting to use local memory pools everywhere we can,
(including our call to SVN::Ra::do_update and all subsequent reporter
calls), there does not appear to be a way to force the Git::SVN::Fetcher
callbacks to use a pool other than the per-SVN::Ra pool.
Git::SVN::Fetcher ends up using the main RA pool which grows
monotonically in size for the lifetime of the RA object.

Thus the only way to free that memory appears to be to destroy and
recreate the RA connection for at every --log-window-size interval.

This reduces memory usage over the course of fetching 10K revisions
using a test repository created with the script at the end of this
commit message.

As reported by time(1) on my x86-64 system:

	before: 54024k
	 after: 28680k

Unfortunately, there remains some yet-to-be-tracked-down slow memory
growth which would be evident as the `nr' parameter increases in
the repository generation script:
-----------------------------8<------------------------------
set -e
tmp=$(mktemp -d svntestrepo-XXXXXXXX)
svnadmin create "$tmp"
repo=file://"$(cd $tmp && pwd)"
svn co "$repo" "$tmp/wd"
cd "$tmp/wd"
if ! test -f a
then
	> a
	svn add a
	svn commit -m 'A'
fi

nr=10000
while test $nr -gt 0
do
	echo $nr > a
	svn commit -q -m A
	nr=$((nr - 1))
done
echo "repository created in $repo"
-----------------------------8<------------------------------

73ffac3b38 git-svn: fix termination issues for remote svn connections
git-svn used in combination with serf to talk to svn repository
served over HTTPS dumps core on termination.

This is caused by a bug in serf, and the most recent serf release
1.3.1 still exhibits the problem; a fix for the bug exists (see
https://code.google.com/p/serf/source/detail?r=2146).

Until the bug is fixed, work around the issue within the git perl
module Ra.pm by freeing the private copy of the remote access object
on termination, which seems to be sufficient to prevent the error
from happening.

Note: Since subversion-1.8.0 and later do require serf-1.2.1 or
later, this issue typically shows up when upgrading to a recent
version of subversion.

Credits go to Jonathan Lambrechts for proposing a fix to Ra.pm,
Evgeny Kotkov and Ivan Zhakov for fixing the issue in serf and
pointing me to that fix.

d301f18160 Git::SVN::*: add missing "NAME" section to perldoc
lexgrog(1) relies on the NAME section to find a manpage's subject's
name and description for easy access later using "man -k".  Add the
section it expects.

Noticed using lintian.

705b49cb81 git-svn: canonicalize newly-minted URLs
Go through all the spots that use the new add_path_to_url() to
make a new URL and canonicalize them.

* copyfrom_path has to be canonicalized else find_parent_branch
  will get confused

* due to the `canonicalize_url($full_url) ne $full_url)` line of
  logic in gs_do_switch(), $full_url is left alone until after.

At this point SVN 1.7 passes except for 3 tests in
t9100-git-svn-basic.sh that look like an SVN bug to do with
symlinks.

d2fd119c4f git-svn: introduce add_path_to_url function
Remove the ad-hoc versions.

This is mostly to normalize the process and ensure the URLs produced
don't have double slashes or anything.

Also provides a place to fix the corner case where a file path
contains a percent sign.

9c27a57b2d git-svn: replace URL escapes with canonicalization
The old hand-rolled URL escape functions were inferior to
canonicalization functions.

Continuing to move towards getting everything canonicalizing the same way.

* Git::SVN->init_remote_config and Git::SVN::Ra->minimize_url both
  have to canonicalize the same way else init_remote_config
  will incorrectly think they're different URLs causing
  t9107-git-svn-migrate.sh to fail.

565e56c2cc Git::SVN{,::Ra}: canonicalize earlier
This canonicalizes paths and urls as early as possible so we don't
have to remember to do it at the point of use.  It will fix a swath
of SVN 1.7 problems in one go.

Its ok to double canonicalize things.

SVN 1.7 still fails, still not worrying about that.

9f7ad1479d git-svn: make Git::SVN::RA a separate file
This slices off another 600 or so lines from the frighteningly long
git-svn.perl script.

The Git::SVN::Ra interface is similar enough to SVN::Ra that it is
probably safe to ignore most of its implementation on first reading.
(Documenting or moving functions that do not fit that pattern is left
as an exercise to the interested reader.)
