[ -C <GIT_repository> ] [ -i ] [ -u ] [-l limit_nr_changes]

|
||||
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
Imports a SVN repository into git. It will either create a new
|
||||
repository, or incrementally import into an existing one.
|
||||
|
||||
SVN access is done by the SVN:: Perl module.
|
||||
|
||||
git-svnimport assumes that SVN repositories are organized into one
|
||||
"trunk" directory where the main development happens, "branch/FOO"
|
||||
directories for branches, and "/tags/FOO" directories for tags.
|
||||
Other subdirectories are ignored.
|
||||
|
||||
git-svnimport creates a file ".git/svn2git", which is required for
|
||||
incremental SVN imports.
|
||||
|
||||
OPTIONS
|
||||
-------
|
||||
-C <target-dir>::
|
||||
The GIT repository to import to. If the directory doesn't
|
||||
exist, it will be created. Default is the current directory.
|
||||
|
||||
-s <start_rev>::
|
||||
Start importing at this SVN change number. The default is 1.
|
||||
+
|
||||
When importing incementally, you might need to edit the .git/svn2git file.
|
||||
|
||||
-i::
|
||||
Import-only: don't perform a checkout after importing. This option
|
||||
ensures the working directory and cache remain untouched and will
|
||||
not create them if they do not exist.
|
||||
|
||||
-t <trunk_subdir>::
|
||||
Name the SVN trunk. Default "trunk".
|
||||
|
||||
-T <tag_subdir>::
|
||||
Name the SVN subdirectory for tags. Default "tags".
|
||||
|
||||
-b <branch_subdir>::
|
||||
Name the SVN subdirectory for branches. Default "branches".
|
||||
|
||||
-o <branch-for-HEAD>::
|
||||
The 'trunk' branch from SVN is imported to the 'origin' branch within
|
||||
the git repository. Use this option if you want to import into a
|
||||
different branch.
|
||||
|
||||
-m::
|
||||
Attempt to detect merges based on the commit message. This option
|
||||
will enable default regexes that try to capture the name source
|
||||
branch name from the commit message.
|
||||
|
||||
-M <regex>::
|
||||
Attempt to detect merges based on the commit message with a custom
|
||||
regex. It can be used with -m to also see the default regexes.
|
||||
You must escape forward slashes.
|
||||
|
||||
-l <max_num_changes>::
|
||||
Limit the number of SVN changesets we pull before quitting.
|
||||
This option is necessary because the SVN library has serious memory
|
||||
leaks; the recommended value for nontrivial imports is 100.
|
||||
|
||||
git-svnimport will still exit with a zero exit code. You can check
|
||||
the size of the file ".git/svn2git" to determine whether to call
|
||||
the importer again.
|
||||
|
||||
-v::
|
||||
Verbosity: let 'svnimport' report what it is doing.
|
||||
|
||||
-d::
|
||||
Use direct HTTP requests if possible. The "<path>" argument is used
|
||||
only for retrieving the SVN logs; the path to the contents is
|
||||
included in the SVN log.
|
||||
|
||||
-D::
|
||||
Use direct HTTP requests if possible. The "<path>" argument is used
|
||||
for retrieving the logs, as well as for the contents.
|
||||
+
|
||||
There's no safe way to automatically find out which of these options to
|
||||
use, so you need to try both. Usually, the one that's wrong will die
|
||||
with a 40x error pretty quickly.
|
||||
|
||||
<SVN_repository_URL>::
|
||||
The URL of the SVN module you want to import. For local
|
||||
repositories, use "file:///absolute/path".
|
||||
+
|
||||
If you're using the "-d" or "-D" option, this is the URL of the SVN
|
||||
repository itself; it usually ends in "/svn".
|
||||
|
||||
<SVN_repository_URL>::
|
||||
The URL of the SVN module you want to import. For local
|
||||
repositories, use "file:///absolute/path".
|
||||
|
||||
<path>
|
||||
The path to the module you want to check out.
|
||||
|
||||
-h::
|
||||
Print a short usage message and exit.
|
||||
|
||||
OUTPUT
|
||||
------
|
||||
If '-v' is specified, the script reports what it is doing.
|
||||
|
||||
Otherwise, success is indicated the Unix way, i.e. by simply exiting with
|
||||
a zero exit status.
