DESCRIPTION
-----------
-'git-svn' is a simple conduit for changesets between Subversion and git.
+'git svn' is a simple conduit for changesets between Subversion and git.
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).

+Once tracking a Subversion repository (with any of the above methods), the git
repository can be updated from Subversion by the 'fetch' command and
Subversion updated from git by the 'dcommit' command.
COMMANDS
--------
---
'init'::
Initializes an empty git repository with additional
- metadata directories for 'git-svn'. The Subversion URL
+ metadata directories for 'git svn'. The Subversion URL
may be specified as a command-line argument, or as full
URL arguments to -T/-t/-b. Optionally, the target
directory to operate on can be specified as a second
--stdlayout;;
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.
Set the 'useSvnsyncProps' option in the [svn-remote] config.
--rewrite-root=<URL>;;
Set the 'rewriteRoot' option in the [svn-remote] config.
---use-log-author;;
- When retrieving svn commits into git (as part of fetch, rebase, or
- dcommit operations), look for the first From: or Signed-off-by: line
- in the log message and use that as the author string.
---add-author-from;;
- When committing to svn from git (as part of commit or dcommit
- operations), if the existing log message doesn't already have a
- From: or Signed-off-by: line, append a From: line based on the
- git commit's author string. If you use this, then --use-log-author
- will retrieve a valid author string for all commits.
+--rewrite-uuid=<UUID>;;
+ Set the 'rewriteUUID' option in the [svn-remote] config.
--username=<USER>;;
For transports that SVN handles authentication for (http,
https, and plain svn), specify the username. For other
When passed to 'init' or 'clone' this regular expression will
be preserved as a config key. See 'fetch' for a description
of '--ignore-paths'.
+--no-minimize-url;;
+ When tracking multiple directories (using --stdlayout,
+ --branches, or --tags options), git svn will attempt to connect
+ to the root (or highest allowed level) of the Subversion
+ repository. This default allows better tracking of history if
+ entire projects are moved within a repository, but may cause
+ issues on repositories where read access restrictions are in
+ place. Passing '--no-minimize-url' will allow git svn to
+ accept URLs as-is without attempting to connect to a higher
+ level directory. This option is off by default when only
+ one URL/branch is tracked (it would do little good).
'fetch'::
Fetch unfetched revisions from the Subversion remote we are
--localtime;;
Store Git commit times in the local timezone instead of UTC. This
- makes 'git-log' (even without --date=local) show the same times
+ makes 'git log' (even without --date=local) show the same times
that `svn log` would in the local timezone.
-
---parent;;
- Fetch only from the SVN parent of the current HEAD.
-
++
This doesn't interfere with interoperating with the Subversion
repository you cloned from, but if you wish for your local Git
repository to be able to interoperate with someone else's local Git
repository, either don't use this option or you should both use it in
the same local timezone.
+--parent;;
+ Fetch only from the SVN parent of the current HEAD.
+
--ignore-paths=<regex>;;
This allows one to specify a Perl regular expression that will
cause skipping of all matching paths from checkout from SVN.
The '--ignore-paths' option should match for every 'fetch'
(including automatic fetches due to 'clone', 'dcommit',
'rebase', etc) on a given repository.

'clone'::
Runs 'init' and 'fetch'. It will automatically create a

and work within that. It accepts all arguments that the
'init' and 'fetch' commands accept; with the exception of

- the working tree; and the 'rebase' command will be able
- to update the working tree with the latest changes.

'rebase'::
This fetches revisions from the SVN parent of the current HEAD

plan to 'dcommit' from. Subversion does not represent merges in any
reasonable or useful fashion; so users using Subversion cannot see any
merges you've made. Furthermore, if you merge or pull from a git branch
that is a mirror of an SVN branch, 'dcommit' may commit to the wrong
branch.

dcommit with SVN is analogous to that.

CONFIGURATION

+'git svn' stores [svn-remote] configuration information in the
repository .git/config file. It is similar the core git
[remote] sections except 'fetch' keys do not accept glob
arguments; but they are instead handled by the 'branches'
however the remote wildcard may be anywhere as long as it's an
independent path component (surrounded by '/' or EOL). This
type of configuration is not automatically created by 'init' and

+should be manually entered with a text-editor or using 'git config'.
+
+It is also possible to fetch a subset of branches or tags by using a
+comma-separated list of names within braces. For example:
+
+------------------------------------------------------------------------
+[svn-remote "huge-project"]
+ url = http://server.org/svn
+ fetch = trunk/src:refs/remotes/trunk
+ branches = branches/{red,green}/src:refs/remotes/branches/*
+ tags = tags/{1.0,2.0}/src:refs/remotes/tags/*
+------------------------------------------------------------------------
+
+Note that git-svn keeps track of the highest revision in which a branch
+or tag has appeared. If the subset of branches or tags is changed after
+fetching, then .git/svn/.metadata must be manually edited to remove (or
+reset) branches-maxRev and/or tags-maxRev as appropriate.
