22 DESCRIPTION
23 -----------
24 Imports a SVN repository into git. It will either create a new
25 repository, or incrementally import into an existing one.
27 SVN access is done by the SVN::Perl module.
29 git-svnimport assumes that SVN repositories are organized into one
30 "trunk" directory where the main development happens, "branches/FOO"
31 directories for branches, and "/tags/FOO" directories for tags.
32 Other subdirectories are ignored.
34 git-svnimport creates a file ".git/svn2git", which is required for
35 incremental SVN imports.
37 OPTIONS
38 -------
39 -C <target-dir>::
40 The GIT repository to import to. If the directory doesn't
41 exist, it will be created. Default is the current directory.
43 -s <start_rev>::
44 Start importing at this SVN change number. The default is 1.
45 +
46 When importing incrementally, you might need to edit the .git/svn2git file.
48 -i::
49 Import-only: don't perform a checkout after importing. This option
50 ensures the working directory and index remain untouched and will
51 not create them if they do not exist.
53 -T <trunk_subdir>::
54 Name the SVN trunk. Default "trunk".
56 -t <tag_subdir>::
57 Name the SVN subdirectory for tags. Default "tags".
59 -b <branch_subdir>::
60 Name the SVN subdirectory for branches. Default "branches".
62 -o <branch-for-HEAD>::
63 The 'trunk' branch from SVN is imported to the 'origin' branch within
64 the git repository. Use this option if you want to import into a
65 different branch.
67 -r::
68 Prepend 'rX: ' to commit messages, where X is the imported
69 subversion revision.
71 -u::
72 Replace underscores in tag names with periods.
74 -I <ignorefile_name>::
75 Import the svn:ignore directory property to files with this
76 name in each directory. (The Subversion and GIT ignore
77 syntaxes are similar enough that using the Subversion patterns
78 directly with "-I .gitignore" will almost always just work.)
80 -A <author_file>::
81 Read a file with lines on the form
82 +
83 ------
84 username = User's Full Name <email@addr.es>
86 ------
87 +
88 and use "User's Full Name <email@addr.es>" as the GIT
89 author and committer for Subversion commits made by
90 "username". If encountering a commit made by a user not in the
91 list, abort.
92 +
93 For convenience, this data is saved to $GIT_DIR/svn-authors
94 each time the -A option is provided, and read from that same
95 file each time git-svnimport is run with an existing GIT
96 repository without -A.
98 -m::
99 Attempt to detect merges based on the commit message. This option
100 will enable default regexes that try to capture the name source
101 branch name from the commit message.
103 -M <regex>::
104 Attempt to detect merges based on the commit message with a custom
105 regex. It can be used with -m to also see the default regexes.
106 You must escape forward slashes.
108 -l <max_rev>::
109 Specify a maximum revision number to pull.
110 +
111 Formerly, this option controlled how many revisions to pull,
112 due to SVN memory leaks. (These have been worked around.)
114 -R <repack_each_revs>::
115 Specify how often git repository should be repacked.
116 +
117 The default value is 1000. git-svnimport will do imports in chunks of 1000
118 revisions, after each chunk the git repository will be repacked. To disable
119 this behavior specify some large value here which is greater than the number of
120 revisions to import.
122 -P <path_from_trunk>::
123 Partial import of the SVN tree.
124 +
125 By default, the whole tree on the SVN trunk (/trunk) is imported.
126 '-P my/proj' will import starting only from '/trunk/my/proj'.
127 This option is useful when you want to import one project from a
128 svn repo which hosts multiple projects under the same trunk.
130 -v::
131 Verbosity: let 'svnimport' report what it is doing.
133 -d::
134 Use direct HTTP requests if possible. The "<path>" argument is used
135 only for retrieving the SVN logs; the path to the contents is
136 included in the SVN log.
138 -D::
139 Use direct HTTP requests if possible. The "<path>" argument is used
140 for retrieving the logs, as well as for the contents.
141 +
142 There's no safe way to automatically find out which of these options to
143 use, so you need to try both. Usually, the one that's wrong will die
144 with a 40x error pretty quickly.
146 <SVN_repository_URL>::
147 The URL of the SVN module you want to import. For local
148 repositories, use "file:///absolute/path".
149 +
150 If you're using the "-d" or "-D" option, this is the URL of the SVN
151 repository itself; it usually ends in "/svn".
153 <path>::
154 The path to the module you want to check out.
156 -h::
157 Print a short usage message and exit.
159 OUTPUT
160 ------
161 If '-v' is specified, the script reports what it is doing.
163 Otherwise, success is indicated the Unix way, i.e. by simply exiting with
164 a zero exit status.
