+NAME
+----
+git-svn - bidirectional operation between a single Subversion branch and git
+
+SYNOPSIS
+--------
+'git-svn' <command> [options] [arguments]
+
+DESCRIPTION
+-----------
+git-svn is a simple conduit for changesets between a single Subversion
+branch and git.
+
+git-svn is not to be confused with git-svnimport. The were designed
+with very different goals in mind.
+
+git-svn is designed for an individual developer who wants a
+bidirectional flow of changesets between a single branch in Subversion
+and an arbitrary number of branches in git. git-svnimport is designed
+for read-only operation on repositories that match a particular layout
+(albeit the recommended one by SVN developers).
+
+For importing svn, git-svnimport is potentially more powerful when
+operating on repositories organized under the recommended
+trunk/branch/tags structure, and should be faster, too.
+
+git-svn mostly ignores the very limited view of branching that
+Subversion has. This allows git-svn to be much easier to use,
+especially on repositories that are not organized in a manner that
+git-svnimport is designed for.
+
+COMMANDS
+--------
+init::
+ Creates an empty git repository with additional metadata
+ directories for git-svn. The Subversion URL must be specified
+ as a command-line argument.
+
+fetch::
+ Fetch unfetched revisions from the Subversion URL we are
+ tracking. refs/remotes/git-svn will be updated to the
+ latest revision.
+
+ Note: You should never attempt to modify the remotes/git-svn
+ branch outside of git-svn. Instead, create a branch from
+ remotes/git-svn and work on that branch. Use the 'commit'
+ command (see below) to write git commits back to
+ remotes/git-svn.
+
+ See 'Additional Fetch Arguments' if you are interested in
+ manually joining branches on commit.
+
+commit::
+ Commit specified commit or tree objects to SVN. This relies on
+ your imported fetch data being up-to-date. This makes
+ absolutely no attempts to do patching when committing to SVN, it
+ simply overwrites files with those specified in the tree or
+ commit. All merging is assumed to have taken place
+ independently of git-svn functions.
+
+rebuild::
+ Not a part of daily usage, but this is a useful command if
+ you've just cloned a repository (using git-clone) that was
+ tracked with git-svn. Unfortunately, git-clone does not clone
+ git-svn metadata and the svn working tree that git-svn uses for
+ its operations. This rebuilds the metadata so git-svn can
+ resume fetch operations. A Subversion URL may be optionally
+ specified at the command-line if the directory/repository you're
+ tracking has moved or changed protocols.
+
+show-ignore::
+ Recursively finds and lists the svn:ignore property on
+ directories. The output is suitable for appending to
+ the $GIT_DIR/info/exclude file.
+
+OPTIONS
+-------
+-r <ARG>::
+--revision <ARG>::
+ Only used with the 'fetch' command.
+
+ Takes any valid -r<argument> svn would accept and passes it
+ directly to svn. -r<ARG1>:<ARG2> ranges and "{" DATE "}" syntax
+ is also supported. This is passed directly to svn, see svn
+ documentation for more details.
+
+ This can allow you to make partial mirrors when running fetch.
+
+-::
+--stdin::
+ Only used with the 'commit' command.
+
+ Read a list of commits from stdin and commit them in reverse
+ order. Only the leading sha1 is read from each line, so
+ git-rev-list --pretty=oneline output can be used.
+
+--rmdir::
+ Only used with the 'commit' command.
+
+ Remove directories from the SVN tree if there are no files left
+ behind. SVN can version empty directories, and they are not
+ removed by default if there are no files left in them. git
+ cannot version empty directories. Enabling this flag will make
+ the commit to SVN act like git.
+
+ repo-config key: svn.rmdir
+
+-e::
+--edit::
+ Only used with the 'commit' command.
+
+ Edit the commit message before committing to SVN. This is off by
+ default for objects that are commits, and forced on when committing
+ tree objects.
+
+ repo-config key: svn.edit
+
+-l<num>::
+--find-copies-harder::
+ Both of these are only used with the 'commit' command.
+
+ They are both passed directly to git-diff-tree see
+ git-diff-tree(1) for more information.
+
+ repo-config key: svn.l
+ repo-config key: svn.findcopiesharder
+
+-A<filename>::
+--authors-file=<filename>::
+
+ Syntax is compatible with the files used by git-svnimport and
+ git-cvsimport:
+
+------------------------------------------------------------------------
+loginname = Joe User <user@example.com>
+------------------------------------------------------------------------
+
+ If this option is specified and git-svn encounters an SVN
+ committer name that does not exist in the authors-file, git-svn
+ will abort operation. The user will then have to add the
+ appropriate entry. Re-running the previous git-svn command
+ after the authors-file is modified should continue operation.
+
+ repo-config key: svn.authors-file
+
+ADVANCED OPTIONS
+----------------
+-b<refname>::
+--branch <refname>::
+ Used with 'fetch' or 'commit'.
+
+ This can be used to join arbitrary git branches to remotes/git-svn
+ on new commits where the tree object is equivalent.
+
+ When used with different GIT_SVN_ID values, tags and branches in
+ SVN can be tracked this way, as can some merges where the heads
+ end up having completely equivalent content. This can even be
+ used to track branches across multiple SVN _repositories_.
+
+ This option may be specified multiple times, once for each
+ branch.
+
+ repo-config key: svn.branch
+
+-i<GIT_SVN_ID>::
+--id <GIT_SVN_ID>::
+ This sets GIT_SVN_ID (instead of using the environment). See
+ the section on "Tracking Multiple Repositories or Branches" for
+ more information on using GIT_SVN_ID.
+
+COMPATIBILITY OPTIONS
+---------------------
+--upgrade::
+ Only used with the 'rebuild' command.
+
+ Run this if you used an old version of git-svn that used
+ "git-svn-HEAD" instead of "remotes/git-svn" as the branch
+ for tracking the remote.
+
+--no-ignore-externals::
+ Only used with the 'fetch' and 'rebuild' command.
+
+ By default, git-svn passes --ignore-externals to svn to avoid
+ fetching svn:external trees into git. Pass this flag to enable
+ externals tracking directly via git.
+
+ Versions of svn that do not support --ignore-externals are
+ automatically detected and this flag will be automatically
+ enabled for them.
+
+ Otherwise, do not enable this flag unless you know what you're
+ doing.
+
+ repo-config key: svn.noignoreexternals
+
+Basic Examples
+~~~~~~~~~~~~~~
+
+Tracking and contributing to an Subversion managed-project:
+
+------------------------------------------------------------------------
+# Initialize a tree (like git init-db):
+ git-svn init http://svn.foo.org/project/trunk
+# Fetch remote revisions:
+ git-svn fetch
+# Create your own branch to hack on:
+ git checkout -b my-branch remotes/git-svn
+# Commit only the git commits you want to SVN:
+ git-svn commit <tree-ish> [<tree-ish_2> ...]
+# Commit all the git commits from my-branch that don't exist in SVN:
+ git-svn commit remotes/git-svn..my-branch
+# Something is committed to SVN, pull the latest into your branch:
+ git-svn fetch && git pull . remotes/git-svn
+# Append svn:ignore settings to the default git exclude file:
+ git-svn show-ignore >> .git/info/exclude
+------------------------------------------------------------------------
+
+DESIGN PHILOSOPHY
+-----------------
+Merge tracking in Subversion is lacking and doing branched development
+with Subversion is cumbersome as a result. git-svn completely forgoes
+any automated merge/branch tracking on the Subversion side and leaves it
+entirely up to the user on the git side. It's simply not worth it to do
+a useful translation when the original signal is weak.
+
+TRACKING MULTIPLE REPOSITORIES OR BRANCHES
+------------------------------------------
+This is for advanced users, most users should ignore this section.
+
+Because git-svn does not care about relationships between different
+branches or directories in a Subversion repository, git-svn has a simple
+hack to allow it to track an arbitrary number of related _or_ unrelated
+SVN repositories via one git repository. Simply set the GIT_SVN_ID
+environment variable to a name other other than "git-svn" (the default)
+and git-svn will ignore the contents of the $GIT_DIR/git-svn directory
+and instead do all of its work in $GIT_DIR/$GIT_SVN_ID for that
+invocation. The interface branch will be remotes/$GIT_SVN_ID, instead of
+remotes/git-svn. Any remotes/$GIT_SVN_ID branch should never be modified
+by the user outside of git-svn commands.
+
+ADDITIONAL FETCH ARGUMENTS
+--------------------------
+This is for advanced users, most users should ignore this section.
+
+Unfetched SVN revisions may be imported as children of existing commits
+by specifying additional arguments to 'fetch'. Additional parents may
+optionally be specified in the form of sha1 hex sums at the
+command-line. Unfetched SVN revisions may also be tied to particular
+git commits with the following syntax:
+
+ svn_revision_number=git_commit_sha1
+
+This allows you to tie unfetched SVN revision 375 to your current HEAD::
+
+ `git-svn fetch 375=$(git-rev-parse HEAD)`
+
+Advanced Example: Tracking a Reorganized Repository
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you're tracking a directory that has moved, or otherwise been
+branched or tagged off of another directory in the repository and you
+care about the full history of the project, then you can read this
+section.
+
+This is how Yann Dirson tracked the trunk of the ufoai directory when
+the /trunk directory of his repository was moved to /ufoai/trunk and
+he needed to continue tracking /ufoai/trunk where /trunk left off.
+
+------------------------------------------------------------------------
+ # This log message shows when the repository was reorganized:
+ r166 | ydirson | 2006-03-02 01:36:55 +0100 (Thu, 02 Mar 2006) | 1 line
+ Changed paths:
+ D /trunk
+ A /ufoai/trunk (from /trunk:165)
+
+ # First we start tracking the old revisions:
+ GIT_SVN_ID=git-oldsvn git-svn init \
+ https://svn.sourceforge.net/svnroot/ufoai/trunk
+ GIT_SVN_ID=git-oldsvn git-svn fetch -r1:165
+
+ # And now, we continue tracking the new revisions:
+ GIT_SVN_ID=git-newsvn git-svn init \
+ https://svn.sourceforge.net/svnroot/ufoai/ufoai/trunk
+ GIT_SVN_ID=git-newsvn git-svn fetch \
+ 166=`git-rev-parse refs/remotes/git-oldsvn`
+------------------------------------------------------------------------
+
+BUGS
+----
+If somebody commits a conflicting changeset to SVN at a bad moment
+(right before you commit) causing a conflict and your commit to fail,
+your svn working tree ($GIT_DIR/git-svn/tree) may be dirtied. The
+easiest thing to do is probably just to rm -rf $GIT_DIR/git-svn/tree and
+run 'rebuild'.
+
+We ignore all SVN properties except svn:executable. Too difficult to
+map them since we rely heavily on git write-tree being _exactly_ the
+same on both the SVN and git working trees and I prefer not to clutter
+working trees with metadata files.
+
+svn:keywords can't be ignored in Subversion (at least I don't know of
+a way to ignore them).
+
+Renamed and copied directories are not detected by git and hence not
+tracked when committing to SVN. I do not plan on adding support for
+this as it's quite difficult and time-consuming to get working for all
+the possible corner cases (git doesn't do it, either). Renamed and
+copied files are fully supported if they're similar enough for git to
+detect them.

- * A pathological example of how this thing works.
- *
- * Suppose we had this commit graph, where chronologically
- * the timestamp on the commit are A <= B <= C <= D <= E <= F
- * and we are trying to figure out the merge base for E and F
- * commits.
- *
- * F
- * / \
- * E A D
- * \ / /
- * B /
- * \ /
- * C
- *
- * First we push E and F to list to be processed. E gets bit 1
- * and F gets bit 2. The list becomes:
- *
- * list=F(2) E(1), result=empty
- *
- * Then we pop F, the newest commit, from the list. Its flag is 2.
- * We scan its parents, mark them reachable from the side that F is
- * reachable from, and push them to the list:
- *
- * list=E(1) D(2) A(2), result=empty
- *
- * Next pop E and do the same.
- *
- * list=D(2) B(1) A(2), result=empty
- *
- * Next pop D and do the same.
- *
- * list=C(2) B(1) A(2), result=empty
- *
- * Next pop C and do the same.
- *
- * list=B(1) A(2), result=empty
- *
- * Now it is B's turn. We mark its parent, C, reachable from B's side,
- * and push it to the list:
- *
- * list=C(3) A(2), result=empty
- *
- * Now pop C and notice it has flags==3. It is placed on the result list,
- * and the list now contains:
- *
- * list=A(2), result=C(3)
- *
- * We pop A and do the same.
- *
- * list=B(3), result=C(3)
- *
- * Next, we pop B and something very interesting happens. It has flags==3
- * so it is also placed on the result list, and its parents are marked
- * stale, retroactively, and placed back on the list:
- *
- * list=C(7), result=C(7) B(3)
- *
- * Now, list does not have any interesting commit. So we find the newest
- * commit from the result list that is not marked stale. Which is
- * commit B.
- *
- *
- * Another pathological example how this thing used to fail to mark an
- * ancestor of a merge base as STALE before we introduced the
- * postprocessing phase (mark_reachable_commits).

-NAME
-----
-git-svn - bidirectional operation between a single Subversion branch and git
-
-SYNOPSIS
---------
-'git-svn' <command> [options] [arguments]
-
-DESCRIPTION
------------
-git-svn is a simple conduit for changesets between a single Subversion
-branch and git.
-
-git-svn is not to be confused with git-svnimport. The were designed
-with very different goals in mind.
-
-git-svn is designed for an individual developer who wants a
-bidirectional flow of changesets between a single branch in Subversion
-and an arbitrary number of branches in git. git-svnimport is designed
-for read-only operation on repositories that match a particular layout
-(albeit the recommended one by SVN developers).
-
-For importing svn, git-svnimport is potentially more powerful when
-operating on repositories organized under the recommended
-trunk/branch/tags structure, and should be faster, too.
-
-git-svn mostly ignores the very limited view of branching that
-Subversion has. This allows git-svn to be much easier to use,
-especially on repositories that are not organized in a manner that
-git-svnimport is designed for.
-
-COMMANDS
---------
-init::
- Creates an empty git repository with additional metadata
- directories for git-svn. The Subversion URL must be specified
- as a command-line argument.
-
-fetch::
- Fetch unfetched revisions from the Subversion URL we are
- tracking. refs/remotes/git-svn will be updated to the
- latest revision.
-
- Note: You should never attempt to modify the remotes/git-svn
- branch outside of git-svn. Instead, create a branch from
- remotes/git-svn and work on that branch. Use the 'commit'
- command (see below) to write git commits back to
- remotes/git-svn.
-
- See 'Additional Fetch Arguments' if you are interested in
- manually joining branches on commit.
-
-commit::
- Commit specified commit or tree objects to SVN. This relies on
- your imported fetch data being up-to-date. This makes
- absolutely no attempts to do patching when committing to SVN, it
- simply overwrites files with those specified in the tree or
- commit. All merging is assumed to have taken place
- independently of git-svn functions.
-
-rebuild::
- Not a part of daily usage, but this is a useful command if
- you've just cloned a repository (using git-clone) that was
- tracked with git-svn. Unfortunately, git-clone does not clone
- git-svn metadata and the svn working tree that git-svn uses for
- its operations. This rebuilds the metadata so git-svn can
- resume fetch operations. A Subversion URL may be optionally
- specified at the command-line if the directory/repository you're
- tracking has moved or changed protocols.
-
-show-ignore::
- Recursively finds and lists the svn:ignore property on
- directories. The output is suitable for appending to
- the $GIT_DIR/info/exclude file.
-
-OPTIONS
--------
--r <ARG>::
---revision <ARG>::
- Only used with the 'fetch' command.
-
- Takes any valid -r<argument> svn would accept and passes it
- directly to svn. -r<ARG1>:<ARG2> ranges and "{" DATE "}" syntax
- is also supported. This is passed directly to svn, see svn
- documentation for more details.
-
- This can allow you to make partial mirrors when running fetch.
-
--::
---stdin::
- Only used with the 'commit' command.
-
- Read a list of commits from stdin and commit them in reverse
- order. Only the leading sha1 is read from each line, so
- git-rev-list --pretty=oneline output can be used.
-
---rmdir::
- Only used with the 'commit' command.
-
- Remove directories from the SVN tree if there are no files left
- behind. SVN can version empty directories, and they are not
- removed by default if there are no files left in them. git
- cannot version empty directories. Enabling this flag will make
- the commit to SVN act like git.
-
- repo-config key: svn.rmdir
-
--e::
---edit::
- Only used with the 'commit' command.
-
- Edit the commit message before committing to SVN. This is off by
- default for objects that are commits, and forced on when committing
- tree objects.
-
- repo-config key: svn.edit
-
--l<num>::
---find-copies-harder::
- Both of these are only used with the 'commit' command.
-
- They are both passed directly to git-diff-tree see
- git-diff-tree(1) for more information.
-
- repo-config key: svn.l
- repo-config key: svn.findcopiesharder
-
--A<filename>::
---authors-file=<filename>::
-
- Syntax is compatible with the files used by git-svnimport and
- git-cvsimport:
-
-------------------------------------------------------------------------
-loginname = Joe User <user@example.com>
-------------------------------------------------------------------------
-
- If this option is specified and git-svn encounters an SVN
- committer name that does not exist in the authors-file, git-svn
- will abort operation. The user will then have to add the
- appropriate entry. Re-running the previous git-svn command
- after the authors-file is modified should continue operation.
-
- repo-config key: svn.authors-file
-
-ADVANCED OPTIONS
-----------------
--b<refname>::
---branch <refname>::
- Used with 'fetch' or 'commit'.
-
- This can be used to join arbitrary git branches to remotes/git-svn
- on new commits where the tree object is equivalent.
-
- When used with different GIT_SVN_ID values, tags and branches in
- SVN can be tracked this way, as can some merges where the heads
- end up having completely equivalent content. This can even be
- used to track branches across multiple SVN _repositories_.
-
- This option may be specified multiple times, once for each
- branch.
-
- repo-config key: svn.branch
-
--i<GIT_SVN_ID>::
---id <GIT_SVN_ID>::
- This sets GIT_SVN_ID (instead of using the environment). See
- the section on "Tracking Multiple Repositories or Branches" for
- more information on using GIT_SVN_ID.
-
-COMPATIBILITY OPTIONS
----------------------
---upgrade::
- Only used with the 'rebuild' command.
-
- Run this if you used an old version of git-svn that used
- "git-svn-HEAD" instead of "remotes/git-svn" as the branch
- for tracking the remote.
-
---no-ignore-externals::
- Only used with the 'fetch' and 'rebuild' command.
-
- By default, git-svn passes --ignore-externals to svn to avoid
- fetching svn:external trees into git. Pass this flag to enable
- externals tracking directly via git.
-
- Versions of svn that do not support --ignore-externals are
- automatically detected and this flag will be automatically
- enabled for them.
-
- Otherwise, do not enable this flag unless you know what you're
- doing.
-
- repo-config key: svn.noignoreexternals
-
-Basic Examples
-~~~~~~~~~~~~~~
-
-Tracking and contributing to an Subversion managed-project:
-
-------------------------------------------------------------------------
-# Initialize a tree (like git init-db):
- git-svn init http://svn.foo.org/project/trunk
-# Fetch remote revisions:
- git-svn fetch
-# Create your own branch to hack on:
- git checkout -b my-branch remotes/git-svn
-# Commit only the git commits you want to SVN:
- git-svn commit <tree-ish> [<tree-ish_2> ...]
-# Commit all the git commits from my-branch that don't exist in SVN:
- git-svn commit remotes/git-svn..my-branch
-# Something is committed to SVN, pull the latest into your branch:
- git-svn fetch && git pull . remotes/git-svn
-# Append svn:ignore settings to the default git exclude file:
- git-svn show-ignore >> .git/info/exclude
-------------------------------------------------------------------------
-
-DESIGN PHILOSOPHY
------------------
-Merge tracking in Subversion is lacking and doing branched development
-with Subversion is cumbersome as a result. git-svn completely forgoes
-any automated merge/branch tracking on the Subversion side and leaves it
-entirely up to the user on the git side. It's simply not worth it to do
-a useful translation when the the original signal is weak.
-
-TRACKING MULTIPLE REPOSITORIES OR BRANCHES
-------------------------------------------
-This is for advanced users, most users should ignore this section.
-
-Because git-svn does not care about relationships between different
-branches or directories in a Subversion repository, git-svn has a simple
-hack to allow it to track an arbitrary number of related _or_ unrelated
-SVN repositories via one git repository. Simply set the GIT_SVN_ID
-environment variable to a name other other than "git-svn" (the default)
-and git-svn will ignore the contents of the $GIT_DIR/git-svn directory
-and instead do all of its work in $GIT_DIR/$GIT_SVN_ID for that
-invocation. The interface branch will be remotes/$GIT_SVN_ID, instead of
-remotes/git-svn. Any remotes/$GIT_SVN_ID branch should never be modified
-by the user outside of git-svn commands.
-
-ADDITIONAL FETCH ARGUMENTS
---------------------------
-This is for advanced users, most users should ignore this section.
-
-Unfetched SVN revisions may be imported as children of existing commits
-by specifying additional arguments to 'fetch'. Additional parents may
-optionally be specified in the form of sha1 hex sums at the
-command-line. Unfetched SVN revisions may also be tied to particular
-git commits with the following syntax:
-
- svn_revision_number=git_commit_sha1
-
-This allows you to tie unfetched SVN revision 375 to your current HEAD::
-
- `git-svn fetch 375=$(git-rev-parse HEAD)`
-
-Advanced Example: Tracking a Reorganized Repository
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-If you're tracking a directory that has moved, or otherwise been
-branched or tagged off of another directory in the repository and you
-care about the full history of the project, then you can read this
-section.
-
-This is how Yann Dirson tracked the trunk of the ufoai directory when
-the /trunk directory of his repository was moved to /ufoai/trunk and
-he needed to continue tracking /ufoai/trunk where /trunk left off.
-
-------------------------------------------------------------------------
- # This log message shows when the repository was reorganized:
- r166 | ydirson | 2006-03-02 01:36:55 +0100 (Thu, 02 Mar 2006) | 1 line
- Changed paths:
- D /trunk
- A /ufoai/trunk (from /trunk:165)
-
- # First we start tracking the old revisions:
- GIT_SVN_ID=git-oldsvn git-svn init \
- https://svn.sourceforge.net/svnroot/ufoai/trunk
- GIT_SVN_ID=git-oldsvn git-svn fetch -r1:165
-
- # And now, we continue tracking the new revisions:
- GIT_SVN_ID=git-newsvn git-svn init \
- https://svn.sourceforge.net/svnroot/ufoai/ufoai/trunk
- GIT_SVN_ID=git-newsvn git-svn fetch \
- 166=`git-rev-parse refs/remotes/git-oldsvn`
-------------------------------------------------------------------------
-
-BUGS
-----
-If somebody commits a conflicting changeset to SVN at a bad moment
-(right before you commit) causing a conflict and your commit to fail,
-your svn working tree ($GIT_DIR/git-svn/tree) may be dirtied. The
-easiest thing to do is probably just to rm -rf $GIT_DIR/git-svn/tree and
-run 'rebuild'.
-
-We ignore all SVN properties except svn:executable. Too difficult to
-map them since we rely heavily on git write-tree being _exactly_ the
-same on both the SVN and git working trees and I prefer not to clutter
-working trees with metadata files.
-
-svn:keywords can't be ignored in Subversion (at least I don't know of
-a way to ignore them).
-
-Renamed and copied directories are not detected by git and hence not
-tracked when committing to SVN. I do not plan on adding support for
-this as it's quite difficult and time-consuming to get working for all
-the possible corner cases (git doesn't do it, either). Renamed and
-copied files are fully supported if they're similar enough for git to
-detect them.
