a004fb923d If deriving SVN_SSH from GIT_SSH on msys, also add quotes
In contrast to GIT_SSH, SVN_SSH requires quotes for paths that contain
spaces. As GIT_SSH will not work if it contains quotes, it is safe to
assume it never contains quotes. Also, adding quotes to SVN_SSH for paths
that do not contain spaces does no harm. So we always add quotes when
deriving SVN_SSH from GIT_SSH on msys.

This fixes msysGit issue 385, see
http://code.google.com/p/msysgit/issues/detail?id=385

075762085c git-svn: allow subset of branches/tags to be specified in glob spec
For very large projects it is useful to be able to clone a subset of the
upstream SVN repo's branches. Allow for this by letting the left-side of
the branches and tags glob specs contain a brace-delineated comma-separated
list of names. e.g.:

	branches = branches/{red,green}/src:refs/remotes/branches/*

3e18ce1ac3 git-svn: allow UUID to be manually remapped via rewriteUUID
In certain situations it may be necessary to manually remap an svn
repostitory UUID. For example:

                  o--- [git-svn clone]
                 /
[origin svn repo]
                 \
                  o--- [svnsync clone]

Imagine that only "git-svn clone" and "svnsync clone" are made available
to external users. Furthur, "git-svn clone" contains only trunk, and for
reasons unknown, "svnsync clone" is missing the revision properties that
normally provide the origin svn repo's UUID.

A git user who has cloned the "git-svn clone" repo now wishes to use
git-svn to pull in the missing branches from the "synsync clone" repo.
In order for git-svn to get the history correct for those branches,
it needs to know the origin svn repo's UUID. Hence rewriteUUID.

1cef6500a9 git-svn: ignore changeless commits when checking for a cherry-pick
Update git-svn to ignore commits that do not change the tree when it is
deciding if an svn merge ticket represents a real branch merge or just a
cherry-pick.

Consider the following integration model in the svn repository:

   F---G  branch1
  /     \
 D  tag1 \   E  tag2
/         \ /
A---B      C  trunk

branch1 is merged to trunk in commit C.

With this patch, git-svn will correctly identify branch1 as a proper merge
parent, instead of incorrectly ignoring it as a cherry-pick.

7a955a5365 git-svn: detect cherry-picks correctly.
The old function was incorrect; in some instances it marks a cherry picked
range as a merged branch (because of an incorrect assumption that
'rev-list COMMIT --not RANGE' would work).  This is replaced with a
function which should detect them correctly, memoized to limit the expense
of dealing with branches with many cherry picks to one 'merge-base' call
per merge, per branch which used cherry picking.

ea020cbd6a git-svn: exclude already merged tips using one rev-list call
The old function would have to check all mentioned merge tips, every time
that the mergeinfo ticket changed.  This involved 1-2 rev-list operation
for each listed mergeinfo line.  If there are a lot of feature branches
being merged into a trunk, this makes for a very expensive operation for
detecting the new parents on every merge.

This new version first uses a single 'rev-list' to figure out which commit
ranges are already reachable from the parents.  This is used to eliminate
the already merged branches from the list.

753dc384dc git svn: handle SVN merges from revisions past the tip of the branch
When recording the revisions that it has merged, SVN sets the top
revision to be the latest revision in the repository, which is not
necessarily a revision on the branch that is being merged from.  When
it is not on the branch, git-svn fails to add the extra parent to
represent the merge because it relies on finding the commit on the
branch that corresponds to the top of the SVN merge range.

In order to correctly handle this case, we look for the maximum
revision less than or equal to the top of the SVN merge range that is
actually on the branch being merged from.

[ew: This includes the following (squashed) commit to prevent
     errors during bisect:]

    git-svn: add (failing) test for SVN 1.5+ merge with intervening commit

    This test exposes a bug in git-svn's handling of SVN 1.5+ mergeinfo
    properties.  The problematic case is when there is some commit on an
    unrelated branch after the last commit on the merged-from branch.
    When SVN records the mergeinfo property, it records the latest
    revision in the whole repository, which, in the problematic case, is
    not on the branch it is merging from.

    To trigger the git-svn bug, we modify t9151 to include two SVN merges,
    the second of which has an intervening commit.  The SVN dump was
    generated using SVN 1.6.6 (on Debian squeeze amd64).

5268f9edc3 svn: assume URLs from the command-line are URI-encoded
And then unescape them when writing to $GIT_CONFIG.

SVN has different rules for repository URLs (usually the root)
and for paths within that repository (below the HTTP layer).
Thus, for the request URI path at the HTTP level, the URI needs
to be encoded.  However, in the body of the HTTP request (the
with underlying SVN XML protocol), those paths should not be
URI-encoded[1].  For non-HTTP(S) requests, SVN appears to be
more flexible and will except weird characters in the URL as
well as URI-encoded ones.

Since users are used to using URLs being entirely URI-encoded,
git svn will now attempt to unescape the path portion of URLs
while leaving the actual repository URL untouched.

This change will be reflected in newly-created $GIT_CONFIG files
only.  This allows users to switch between svn(+ssh)://, file://
and http(s):// urls without changing the fetch/branches/tags
config keys.  This won't affect existing imports at all (since
things didn't work before this commit anyways), and will allow
users to force escaping into repository paths that look like
they're escaped (but are not).

Thanks to Mike Smullin for the original bug report and Björn
Steinbrink for summarizing it into testable cases for me.

5f8b2cbacd git svn: make minimize URL more reliable over http(s)
In addition to path-based restrictions, Subversion servers over
http(s) may have access controls implemented via the LimitExcept
directive in Apache.  In some cases, LimitExcept may be
(arguably) misconfigured to not allow REPORT requests while
allowing OPTIONS and PROPFIND.

This caused problems with our existing minimize_url logic that
only issued OPTIONS and PROPFIND requests when connecting and
using SVN::Ra::get_latest_revnum.  We now call SVN::Ra::get_log
if get_latest_revnum succeeds, resulting in a REPORT request
being sent.  This will increase our chances of tripping access
controls before we start attempting to fetch history.

Relying on SVN::Core::INVALID_REVNUM (-1) as the "start"
argument to SVN::Ra::get_log() proved unreliable with http(s)
URLs so the result of SVN::Ra::get_latest_revnum() is used as
the "start" argument instead.

0b2af457a4 git-svn: Fix branch detection when repository root is inaccessible
For the case of multiple projects sharing a single SVN repository, it is
common practice to create the standard SVN directory layout within a
subdirectory for each project. In such setups, access control is often
used to limit what projects a given user may access. git-svn failed to
detect branches (e.g. when passing --stdlayout to clone) because it
relied on having access to the root directory in the repository. This
patch solves this problem by making git-svn use paths relative to the
given repository URL instead of the repository root.

This enables git-svn.perl to read multiple 'branches' and 'tags' entries in
svn-remote config sections.  The init and clone subcommands also support
multiple --branches and --tags arguments.

The branch (and tag) subcommand gets a new argument: --destination (or -d).
This argument is required if there are multiple branches (or tags) entries
configured for the remote Subversion repository.  The argument's value
specifies which branch (or tag) path to use to create the branch (or tag).
The specified value must match the left side (without wildcards) of one of
the branches (or tags) refspecs in the svn-remote's config.

5eec27e35f git-svn: let 'dcommit $rev' work on $rev instead of HEAD
'git svn dcommit' takes an optional revision argument, but the meaning
of it was rather scary.  It completely ignored the current state of
the HEAD, only looking at the revisions between SVN and $rev.  If HEAD
was attached to $branch, the branch lost all commits $rev..$branch in
the process.

Considering that 'git svn dcommit HEAD^' has the intuitive meaning
"dcommit all changes on my branch except the last one", we change the
meaning of the revision argument.  git-svn temporarily checks out $rev
for its work, meaning that

* if a branch is specified, that branch (_not_ the HEAD) is rebased as
  part of the dcommit,

* if some other revision is specified, as in the example, all work
  happens on a detached HEAD and no branch is affected.

advanced username operations than the authors file will allow.  For

Notes:

* If both --authors-name and --authors-prog are given, the former is
  tried first, falling back to the later.

* The program is called once per unique SVN username, and the result is
  cached.

* The command-line argument must be the path to a program, not a generic
  shell command line.  The absolute path to this program is taken at
  startup since the git-svn script changes directory during operation.

* The option is not enabled for `git svn log'.

The parse_svn_date sub expects there always are one or more digits after

and results in a failure like this.

edc662f929 git-svn: add --ignore-paths option for fetching
This will be useful when somebody want to checkout something partially from
repository with some non-standart layout or exclude some files from it.
Example: repository has structure /module-{a,b,c}/{trunk,branches,tags}/...
Modules are interdependent, and you want it to be single repostory (to commit
to all modules simultaneously and view complete history), but do not want
branches and tags be checked out into working copy.
Other use case is excluding some large blobs.

The quirk for now is that user must specify this option every fetch/rebase;
in other case he may get extra files or "file not found" errors. It may be
will be resolved by adding regular expression to .git/config into
[svn-remote ...] to make it persistent.

1ef626b4b6 git-svn: fix SVN 1.1.x compatibility
The get_log() function in the Perl SVN API introduced the limit
parameter in 1.2.0.  However, this got discarded in our SVN::Ra
compatibility layer when used with SVN 1.1.x.  We now emulate
the limit functionality in older SVN versions by preventing the
original callback from being called if the given limit has been
reached.  This emulation is less bandwidth efficient, but SVN
1.1.x is becoming rarer now.

Additionally, the --limit parameter in svn(1) uses the
aforementioned get_log() functionality change in SVN 1.2.x.
t9129 no longer depends on --limit to work and instead uses
Perl to parse out the commit message.

baf5fa8a7f git-svn: better attempt to handle broken symlink updates
This is a followup to 7fc35e0e94,
(workaround a for broken symlinks in SVN).

Since broken SVN clients can commit svn:special files without
the magic "link " prefix, this can affect delta application
when we update the broken svn:special file.  So now we fall
back and retry the delta application on symlinks if having
a "link " prefix fails.

Our behavior differs from svn(1) (v1.5.1) slightly:

  When a svn:special file is created w/o a "link " prefix, svn
  will create a regular file (mode 100644 to git) with the
  contents of the blob as-is.

  Our behavior is to continue creating the symlink (mode 120000
  to git) with the contents of the blob as-is.  While this
  differs from current svn(1) behavior, this is easier and more
  efficient to implement (and the correctness of the svn(1) is
  debatable, since it's a workaround for a bug in the first
  place).

More information on this SVN bug is described here:

Broken SVN clients generate empty files with the svn:special set
to '*'.  This attempts to denote a symlink pointing to a file
with an empty path (""), which cannot be generated on a POSIX

Thus, we mimic the behavior of svn(1) and create a zero-byte
file in our tree.

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.

a0fbc87cff git-svn: Make branch use correct svn-remote
The 'branch' subcommand incorrectly had the svn-remote to use hardcoded
as 'svn', the default remote name.  This meant that branches derived
from other svn-remotes would try to use the branch and tag configuration
for the 'svn' remote, potentially copying would-be branches to the wrong
place in SVN, into the branch namespace for another project.

Fix this by using the remote name extracted from the svn info for the
specified git ref.  Add a testcase for this behaviour.

16fc08e2d8 git-svn: respect i18n.commitencoding config
SVN itself always stores log messages in the repository as
UTF-8.  git always stores/retrieves everything as raw binary
data with no transformations whatsoever.

To interact with SVN, we need to encode log messages as UTF-8
before sending them to SVN, as SVN cannot do it for us.  When
retrieving log messages from SVN, we also need to (attempt to)
reencode the UTF-8 log message back to the user-specified commit
encoding.

Note, handling i18n.logoutputencoding for "git svn log" also
needs to be done in a future change.

Also, this change only deals with the encoding of commit
messages and nothing else (path names, blob content, ...).

2beec89733 git-svn: do a partial rebuild if rev_map is out-of-date
Suppose you're using git-svn to work with a certain SVN repository.
Since you don't like 'git-svn fetch' to take forever, and you don't want
to accidentally interrupt it and end up corrupting your repository, you
set up a remote Git repository to mirror the SVN repository, which does
its own 'git-svn fetch' on a cronjob; now you can 'git-fetch' from the
Git mirror into your local repository, and still dcommit to SVN when you
have changes to push.

After you do this, though, git-svn will get very confused if you ever
try to do 'git-svn fetch' in your local repository again, since its
rev_map will differ from the branch's head, and it will be unable to
fetch new commits from SVN because of the metadata conflict.  But all
the necessary metadata are there in the Git commit message; git-svn
already knows how to rebuild rev_map files that get blown away, by
using the metadata.

This patch teaches git-svn do a partial rebuild of the rev_map to
match the true state of the branch, if it ever is used to fetch again.

This will only work for projects not using either noMetadata or
useSvmProps configuration options; if you are using these options,
git-svn will fall back to the previous behaviour.

2cf3e3ac02 git-svn: match SVN 1.5 behaviour of info' on unknown item
Previously 'git svn info unknown-file' only announced its failure (in
the SVN 1.4 style, "not a versioned resource"), and exited
successfully.

It is desirable to actually exit with failure, so change the code to
exit(1) under this condition.  Since that is already halfway SVN 1.5
compatibility, also change the error output to match 1.5.

05427b91f0 git svn info: always quote URLs in 'info' output
Changes 'git svn info' to always URL-escape the 'URL' and 'Repository'
fields and --url output, like SVN (at least 1.5) does.

Note that reusing the escape_url() further down in Git::SVN::Ra is not
possible because it only triggers for http(s) URLs.  I did not know
whether extending it to all schemes would break SVN access anywhere,
so I made a new one that quotes in all schemes.

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

  * removed unrelated line-wrapping changes

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.

find-rev and rebase error out on svm because git-svn doesn't trace the

This fixes Git::SVN::find_by_url to find branches based on the

and working_head_info use the information they have to correctly track
the source repository. This is enough to get find-rev and rebase

With this commit, git-svn makes sure the path doesn't start with a

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.
