ebdf7b9522 git-svn: avoid network timeouts for long-running fetches
Long-running fetches run inside children to avoid memory leaks.
When we refork, the connection in the parent can be idle for a
long time; attempting to reuse it in the next child can result
in timeouts.

6173c197c9 git-svn: avoid fetching files twice in the same revision
SVN is not entirely consistent in returning log information and
sometimes returns file information when adding subdirectories,
and sometimes it does not (only returning information about the
directory that was added).  This caused git-svn to occasionally
add a file to the list of files to be fetched twice.  Now we
change the data structure to be hash to avoid repeated fetches.

As of now (in master), this only affects repositories fetched
without deltas enabled (file://, and when manually overriden
with GIT_SVN_DELTA_FETCH=0); so this bug mainly affects users of
1.4.4.1 and maint.

Thanks to Florian Weimer for reporting this bug.

1ca7558dd8 git-svn: fix multi-init
After the bugfix to connect to repositories where the user has
limited read permissions, multi-init was broken due to our
SVN::Ra connection being limited to working in a subdirectory;
so we now create a new Ra connection for init-ing branches
and another for tags

Along with that fix, allow the user to use the command-line
option flags for multi-init (--revision being the most notable;
but also --no-auth-cache, --config-dir, --username (for passing
to SVN), and --shared/--template for passing to git-init-db

0864e3ba12 git-svn: fix output reporting from the delta fetcher
There was nothing printed in the code originally because I left
out a pair of parentheses.  Nevertheless, the affected code has
been replaced with a more efficient version that respects the -q
flag as well as requiring less bandwidth.

We save some bandwidth by not requesting changed paths
information when calling get_log() since we're using the delta
fetcher.

747fa12cef git-svn: correctly access repos when only given partial read permissions
Sometimes users are given only read access to a subtree inside a
repository, and git-svn could not read log information (and thus
fetch commits) when connecting a session to the root of the
repository.  We now start an SVN::Ra session with the full URL
of what we're tracking, and not the repository root as before.

This change was made much easier with a cleanup of
repo_path_split() usage as well as improving the accounting of
authentication batons.

45bf473a7b git-svn: fix dcommit losing changes when out-of-date from svn
There was a bug in dcommit (and commit-diff) which caused deltas
to be generated against the latest version of the changed file
in a repository, and not the revision we are diffing (the tree)
against locally.

This bug can cause recent changes to the svn repository to be
silently clobbered by git-svn if our repository is out-of-date.

Thanks to Steven Grimm for noticing the bug.

The (few) people using the commit-diff command are now required
to use the -r/--revision argument.  dcommit usage is unchanged.

f7197dff15 git-svn: reduce memory usage for large commits
apply_textdelta and send_stream can use a separate pool from the
rest of the editor interface, so we'll use a separate SVN::Pool
for them and clear the pool after each file is sent to SVN.

This drastically reduces memory usage per-changeset committed,
and makes large commits (and initial imports) of several
thousand files possible.

83e9940a5e git-svn: add a message encouraging use of SVN::* libraries
I'm using svn 1.4.0-4 in Debian unstable and apparently there's
a regression on the SVN side that prevents a symlink from
becoming a regular file (which git supports, of course).

It's not a noticeable regression for most people, but this broke
the full-svn-tests target in t/Makefile for me.

The SVN::* Perl libraries seem to have matured and improved over
the past year, and git-svn has supported them for several months
now, so with that I encourage all users to start using the
SVN::* Perl libraries with git-svn.

74a31a100a git-svn: log command fixes
Change the --verbose flag to more closely match svn.  I was
somehow under the impression that --summary included --raw diff
output, but I was wrong.  We now pass -r --raw --name-status as
arguments if passed -v/--verbose.

-r (recursive) is passed by default, since users usually want
it, and accepting it causes difficulty with the -r<revision>
option used by svn users.  A --non-recursive switch has been
added to disable this.

Of course, --summary, --raw, -p and any other git-log options
can still be passed directly (without --name-status).

Also, several warnings about referencing undefined variables
have been fixed.

f7bae37f9a Allow 'svn fetch' on '(no date)' revisions in Subversion.
Added --ignore-nodate to allow 'git svn fetch' to import revisions
from Subversion which have '(no date)' listed as the date of the
revision.  By default 'git svn fetch' will crash with an error
when encountering such a revision.  The user may restart the fetch
operation by adding --ignore-nodate if they want to continue tracking
that repository.

I'm not entirely sure why a centralized version control system such
as Subversion permits revisions to be created with absolutely no
date/time associated with it but it apparently is possible as one
of the Subversion repositories that I'm tracking with 'git svn'
created such a revision on '(no date)' and by '(no user)'.

Updated from the original patch to workaround some SVN bug

Somehow connecting to a repository with the full url makes the
returned SVN::Ra object act strangely and break things, so now
we just drop the SVN::Ra object that we made our initial

17a10f3709 git-svn: correctly kill keyword expansion without munging EOLs
This bugfix applies to users of the svn command-line client only.

We no longer muck with newlines when killing keyword expansion.
This tended to generate unintended diffs in commits because svn
revert -R would destroy the manual EOL changes we were doing. Of
course, we didn't need the EOL munging in the first place, as
svn seems to do it for us even in the text-base files.

Now we set the mtime and atime the files changed by keyword
expansion killing to avoid triggering a change on svn revert,
which svn still seems to want to do.
