It provides a bidirectional flow of changes between a Subversion and a git
repository.
It provides a bidirectional flow of changes between a Subversion and a git
repository.
-'git-svn' can track a single Subversion branch simply by using a
-URL to the branch, follow branches laid out in the Subversion recommended
-method (trunk, branches, tags directories) with the --stdlayout option, or
-follow branches in any layout with the -T/-t/-b options (see options to
-'init' below, and also the 'clone' command).
+'git-svn' can track a standard Subversion repository,
+following the common "trunk/branches/tags" layout, with the --stdlayout option.
+It can also follow branches and tags in any layout with the -T/-t/-b options
+(see options to 'init' below, and also the 'clone' command).

These are optional command-line options for init. Each of
these flags can point to a relative repository path
- (--tags=project/tags') or a full url
- (--tags=https://foo.org/project/tags). The option --stdlayout is
+ (--tags=project/tags) or a full url
+ (--tags=https://foo.org/project/tags).
+ You can specify more than one --tags and/or --branches options, in case
+ your Subversion repository places tags or branches under multiple paths.
+ The option --stdlayout is
a shorthand way of setting trunk,tags,branches as the relative paths,
which is the Subversion default. If any of the other options are given
as well, they take precedence.

It is recommended that you run 'git-svn' fetch and rebase (not
pull or merge) your commits against the latest changes in the
SVN repository.

This is advantageous over 'set-tree' (below) because it produces
cleaner, more linear history.

+ If more than one --branches (or --tags) option was given to the 'init'
+ or 'clone' command, you must provide the location of the branch (or
+ tag) you wish to create in the SVN repository. The value of this
+ option must match one of the paths specified by a --branches (or
+ --tags) option. You can see these paths with the commands
++
+ git config --get-all svn-remote.<name>.branches
+ git config --get-all svn-remote.<name>.tags
++
+where <name> is the name of the SVN repository as specified by the -R option to
+'init' (or "svn" by default).

'tag'::
Create a tag in the SVN repository. This is a shorthand for
'branch -t'.

+'reset'::
+ Undoes the effects of 'fetch' back to the specified revision.
+ This allows you to re-'fetch' an SVN revision. Normally the
+ contents of an SVN revision should never change and 'reset'
+ should not be necessary. However, if SVN permissions change,
+ or if you alter your --ignore-paths option, a 'fetch' may fail
+ with "not found in commit" (file not previously visible) or
+ "checksum mismatch" (missed a modification). If the problem
+ file cannot be ignored forever (with --ignore-paths) the only
+ way to repair the repo is to use 'reset'.
+
+Only the rev_map and refs/remotes/git-svn are changed. Follow 'reset'
+with a 'fetch' and then 'git-reset' or 'git-rebase' to move local
+branches onto the new tree.
+
+-r/--revision=<n>;;
+ Specify the most recent revision to keep. All later revisions
+ are discarded.
+-p/--parent;;
+ Discard the specified revision as well, keeping the nearest
+ parent instead.
+Example:;;
+Assume you have local changes in "master", but you need to refetch "r2".
+
+------------
+ r1---r2---r3 remotes/git-svn
+ \
+ A---B master
+------------
+
+Fix the ignore-paths or SVN permissions problem that caused "r2" to
+be incomplete in the first place. Then:
+
+[verse]
+git svn reset -r2 -p
+git svn fetch
+
+------------
+ r1---r2'--r3' remotes/git-svn
+ \
+ r2---r3---A---B master
+------------
+
+Then fixup "master" with 'git-rebase'.
+Do NOT use 'git-merge' or your history will not be compatible with a
+future 'dcommit'!
+
+[verse]
+git rebase --onto remotes/git-svn A^ master
+
+------------
+ r1---r2'--r3' remotes/git-svn
+ \
+ A'--B' master

+When using multiple --branches or --tags, 'git-svn' does not automatically
+handle name collisions (for example, if two branches from different paths have
+the same name, or if a branch and a tag have the same name). In these cases,
+use 'init' to set up your git repository then, before your first 'fetch', edit
+the .git/config file so that the branches and tags are associated with
+different name spaces. For example:
+
+ branches = stable/*:refs/remotes/svn/stable/*
+ branches = debug/*:refs/remotes/svn/debug/*
