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.

61aeeefd29 git-svn: fix handling of even funkier branch names
Apparently do_switch() tolerates the lack of escaping in less

need to escape them properly.  It strangely maintains compatible

711521e246 git-svn: fix dcommit to urls with embedded usernames
Don't rely on the extracted URL from working_head_info since that has the
username removed.  Instead use the $gs->full_url method (as before with
ba24e74 (git-svn: add ability to specify --commit-url for dcommit,
2008-08-07)) to give us the URL to commit to if --commit-url is not
specified.

Aditionally, since we clean usernames from URLs, checking the URL after
rebase can fail because it doesn't match the URL we used to commit; so
unconditionally provide a username-free URL for checking the result of the
refetch.

510b0945d0 git-svn: Reduce temp file usage when dealing with non-links
Currently, in sub 'close_file', git-svn creates a temporary file and
copies the contents of the blob to be written into it. This is useful
for symlinks because svn stores symlinks in the form:

link $FILE_PATH

Git creates a blob only out of '$FILE_PATH' and uses file mode to
indicate that the blob should be interpreted as a symlink.

As git-hash-object is invoked with --stdin-paths, a duplicate of the
link from svn must be created that leaves off the first five bytes,
i.e. 'link '. However, this is wholly unnecessary for normal blobs,
though, as we already have a temp file with their contents. Copying
the entire file gains nothing, and effectively requires a file to be
written twice before making it into the object db.

This patch corrects that issue, holding onto the substr-like
duplication for symlinks, but skipping it altogether for normal blobs
by reusing the existing temp file.

0b19138ba3 git-svn: Make it incrementally faster by minimizing temp files
Currently, git-svn would create a temp file on four occasions:
1. Reading a blob out of the object db
2. Creating a delta from svn
3. Hashing and writing a blob into the object db
4. Reading a blob out of the object db (in another place in code)

Any time git-svn did the above, it would dutifully create and then
delete said temp file.  Unfortunately, this means that between 2-4
temporary files are created/deleted per file 'add/modify'-ed in
svn (O(n)).  This causes significant overhead and helps the inode
counter to spin beautifully.

By its nature, git-svn is a serial beast.  Thus, reusing a temp file
does not pose significant problems.  "truncate and seek" takes much
less time than "unlink and create".  This patch centralizes the
tempfile creation and holds onto the tempfile until they are deleted
on exit.  This significantly reduces file overhead, now requiring
at most three (3) temp files per run (O(1)).

570d35c26d git-svn: Allow deep branch names by supporting multi-globs
Some repositories use a deep branching strategy, such as:

    branches/1.0/1.0.rc1
    branches/1.0/1.0.rc2
    branches/1.0/1.0.rtm
    branches/1.0/1.0.gold

Only allowing a single glob stiffles this.

This change allows for a single glob 'set' to accept this deep
branching strategy.

The ref glob depth must match the branch glob depth.  When using
the -b or -t options for init or clone, this is automatically
done.

For example, using the above branches:

  svn-remote.svn.branches = branches/*/*:refs/remote/*/*

gives the following branch names:

  1.0/1.0.rc1
  1.0/1.0.rc2
  1.0/1.0.rtm
  1.0/1.0.gold

ba24e7457a git-svn: add ability to specify --commit-url for dcommit
This allows one to use public svn:// URLs for fetch and
svn+ssh:// URLs for committing (without using the complicated
rewriteRoot option, reimporting or git-filter-branch).

Using this can also help avoid unnecessary server
authentication/encryption overhead on busy SVN servers.

Along with the new --revision option, this can also be allowed
to override the branch detection in dcommit, too.  This is
potentially dangerous and not recommended!  (And also purposely
undocumented, but the loaded gun is there in case somebody
wants to make it safe).

611921654f git-svn: Abort with an error if 'fetch' parameter is invalid.
Previously, if a config entry looked like this:

         svn-remote.svn.fetch=:refs/heads/whatever

git-svn would silently do nothing if you asked it to "git svn fetch", and
give a strange error if asked to "git svn dcommit".  What it really wants is
a line that looks like this:

	svn-remote.svn.fetch=:refs/remotes/whatever

So we should simply abort if we get the wrong thing.

On the other hand, there's actually no good reason for git-svn to enforce
using the refs/remotes namespace, but the code seems to have hardcoded this
in several places and I'm not brave enough to try to fix it all right now.

29c70e0b3e git-svn: avoid filling up the disk with temp files.
Commit ffe256f9ba ("git-svn: Speed up fetch")
introduced changes that create a temporary file for each object fetched by
svn.  These files should be deleted automatically, but perl apparently
doesn't do this until the process exits (or perhaps when its garbage
collector runs).

This means that on a large fetch, especially with lots of branches, we
sometimes fill up /tmp completely, which prevents the next temp file from
being written completely.  This is aggravated by the fact that a new temp
file is created for each updated file, even if that update produces a file
identical to one already in git.  Thus, it can happen even if there's lots
of disk space to store the finished repository.

We weren't adequately checking for write errors, so this would result in an
invalid file getting committed, which caused git-svn to fail later with an
invalid checksum.

This patch adds a check to syswrite() so similar problems don't lead to
corruption in the future.  It also unlink()'s each temp file explicitly
when we're done with it, so the disk doesn't need to fill up.

74b1e12357 git-svn: make rebuild respect rewriteRoot option
Suppose someone fetches git-svn-ified commits from another repo and then
attempts to use 'git-svn init --rewrite-root=foo bar'. Using git svn rebase
after that will fail badly:

 * For each commit tried by working_head_info, rebuild is called indirectly.
 * rebuild will iterate over all commits and skip all of them because the
   URL does not match. Because of that no rev_map file is generated at all.
 * Thus, rebuild will run once for every commit. This takes ages.
 * In the end there still isn't any rev_map file and thus working_head_info
   fails.

Addressing this behaviour fixes an apparently not too uncommon problem with
providing git-svn mirrors of Subversion repositories. Some repositories are
accessed using different URLs depending on whether the user has push
privileges or not. In the latter case, an anonymous URL is often used that
differs from the push URL. Providing a mirror that is usable in both cases
becomes a lot more possible with this change.

328eb9b32f git-svn: don't append extra newlines at the end of commit messages.
In git, all commits end in exactly one newline character.  In svn, commits
end in zero or more newlines.  Thus, when importing commits from svn into
git, git-svn always appends two extra newlines to ensure that the
git-svn-id: line is separated from the main commit message by at least one
blank line.

Combined with the terminating newline that's always present in svn commits
produced by git, you usually end up with two blank lines instead of one
between the commit message and git-svn-id: line, which is undesirable.

Instead, let's remove all trailing whitespace from the git commit on the way
through to svn.

b7166cce8c git-svn fails in prop_walk if $self->{path} is not empty
If url://repo/trunk is the current Git branch, prop_walk strips trunk
from the path name. That is useful as, for example "git svn show-ignore"
should not return results like

    trunk/foo

but

    foo

if svn:ignore for trunk includes foo.

The problem now is that prop_walk strips trunk from the path and then
calls itself recursively. But now trunk is missing in the path and
get_dir fails, because it is called for a non existing path.

The attached patch fixed the problem, by adding the previously stipped
$self->{path} in the recursive call. I tested it with my current
git-svn repository for the commands show-ignore and show-external.

d1a8d0ea5f git-svn: fix cloning of HTTP URLs with '+' in their path
With this, git svn clone -s http://svn.gnome.org/svn/gtk+
is successful.

Also modified the funky rename test for this, which _does_
include escaped '+' signs for HTTP URLs.  SVN seems to accept
either "+" or "%2B" in filenames and directories (just not the
main URL), so I'll leave it alone for now.

c4c66b2669 git-svn: Make create-ignore use git add -f
When having a svn:ignore that ignores the .gitignore file the -f
option to git add must be used to avoid git complaining about adding
an ignored file and hence stop the process of creating .gitignores.

6aa9ba14a0 git-svn: Add --add-author-from option.
This option adds a From: line (based on the commit's author information)
at the beginning of the body of the commit log message when sending to
svn, if a From: or Signed-off-by: header does not exist.

This, combined with --use-log-author, can retain the author field of commits
through a round trip from git to svn and back.

abfa533dea git-svn: Same default as cvsimport when using --use-log-author
When using git-cvsimport, the author is inferred from the cvs commit,
e.g. cvs commit logname is foobaruser, then the author field in git
results in:

Author: foobaruser <foobaruser>

Which is not perfect, but perfectly acceptable given the circumstances.

The default git-svn import however, results in:

Author: foobaruser <foobaruser@acf43c95-373e-0410-b603-e72c3f656dc1>

When using mixes of imports, from CVS and SVN into the same git
repository, you'd like to harmonise the imports to the format cvsimport
uses.
git-svn supports an experimental option --use-log-author which currently
results in the same logentry as without that option when no From: or
Signed-off-by: is found in the logentry ($email currently ends up empty,
and hence is generated again).

This patches harmonises the result with cvsimport, and makes
git-svn --use-log-author produce:

Author: foobaruser <foobaruser>

59b0c24daa git-svn: detect and fail gracefully when dcommitting to a void
The command

  git svn clone (URL of an empty SVN repo here)

works, creates an empty git repository. I can perform the initial
commit there, but then, "git svn dcommit" says :

Use of uninitialized value in concatenation (.) or string at .../git-svn line 414.
Committing to  ...
Unable to determine upstream SVN information from HEAD history

I guess a correct management of the initial commit in git-svn would be
hard to implement, but at least, the error message can be improved.
First step is something like the patch below, and better would be for
"git svn clone" to warn that it won't be able to do much with the
cloned repo.

9231f500c3 git-svn bug with blank commits and author file
When trying to import from svn using an author file, git-svn bails out
if it encounters a blank author. The attached patch changes this
behavior and allow using the author file with blanks authors.

I came across this bug while importing from a cvs2svn repo where the
initial revision (1) has a blank author. This doesn't break the behavior
of bailing out when an unknown author is encountered.

b6309ac2b8 Force the medium pretty format on calls to git log
If a user has customized format.pretty in config, git-svn rebase fails with:

	Unable to determine upstream SVN information from working tree history

because the command expects to read the commit log in the default format.

This fixes the command to explicitly ask for the format it wants to read
from.

f61cc48d28 git-svn: fix following renamed paths when tracking a single path
When using git-svn to follow only a single (empty) path per
svn-remote (i.e. not using --stdlayout), following the history
of a renamed path was broken in
c586879cdf.

This reverts the regression for the single (emtpy) path per
svn-remote case.

To avoid breaking the tests in a committed revision, this is an
addendum to a patch originally submitted by

  Santhosh Kumar Mani <santhoshmani@gmail.com>:
  > git-svn: add test for renamed directory fetch
  >
  > This test tries to fetch a directory which had renames in the
  > history from a SVN repository.

  [ew: unneccesary dependency on the starting an HTTP server
   removed from Santhosh's original test.]

git-svn project names are percent-escaped ever since f5530b8
(git-svn: support for funky branch and project names over HTTP(S),

Unfortunately this breaks the scenario where the user hands git-svn an
already-escaped URI.  Fix the regexp to skip over what looks like
existing percent escapes, and test this scenario.

ed0b9d4309 git-svn: don't blindly append '*' to branch/tags config
Previously, git-svn would blindly append '*' even if it was specified by
the user during initialization (for certain SVN setups, it is
necessary).

Now, the following command will work correctly:

  git svn init -T trunk/docutils \
               -t 'tags/*/docutils' \
               -b 'branches/*/docutils' \
               svn://svn.berlios.de/docutils
