hg convert [OPTION]... SOURCE [DEST [REVMAP]] Convert a foreign SCM repository to a Mercurial one. Accepted source formats: - Mercurial - CVS - Darcs - git - Subversion - GNU Arch Accepted destination formats: - Mercurial - Subversion (history on branches is not preserved) If no revision is given, all revisions will be converted. Otherwise, convert will only import up to the named revision (given in a format understood by the source). If no destination directory name is specified, it defaults to the basename of the source with '-hg' appended. If the destination repository doesn't exist, it will be created. If isn't given, it will be put in a default location (/.hg/shamap by default). The is a simple text file that maps each source commit ID to the destination ID for that revision, like so: If the file doesn't exist, it's automatically created. It's updated on each commit copied, so convert-repo can be interrupted and can be run repeatedly to copy new commits. The [username mapping] file is a simple text file that maps each source commit author to a destination commit author. It is handy for source SCMs that use unix logins to identify authors (eg: CVS). One line per author mapping and the line format is: srcauthor=whatever string you want The filemap is a file that allows filtering and remapping of files and directories. Comment lines start with '#'. Each line can contain one of the following directives: include path/to/file exclude path/to/file rename from/file to/file The 'include' directive causes a file, or all files under a directory, to be included in the destination repository, and the exclusion of all other files and dirs not explicitely included. The 'exclude' directive causes files or directories to be omitted. The 'rename' directive renames a file or directory. To rename from a subdirectory into the root of the repository, use '.' as the path to rename to. The splicemap is a file that allows insertion of synthetic history, letting you specify the parents of a revision. This is useful if you want to e.g. give a Subversion merge two parents, or graft two disconnected series of history together. Each entry contains a key, followed by a space, followed by one or two values, separated by spaces. The key is the revision ID in the source revision control system whose parents should be modified (same format as a key in .hg/shamap). The values are the revision IDs (in either the source or destination revision control system) that should be used as the new parents for that node. Mercurial Source ----------------- --config convert.hg.saverev=True (boolean) allow target to preserve source revision ID Subversion Source ----------------- Subversion source detects classical trunk/branches/tags layouts. By default, the supplied "svn://repo/path/" source URL is converted as a single branch. If "svn://repo/path/trunk" exists it replaces the default branch. If "svn://repo/path/branches" exists, its subdirectories are listed as possible branches. If "svn://repo/path/tags" exists, it is looked for tags referencing converted branches. Default "trunk", "branches" and "tags" values can be overriden with following options. Set them to paths relative to the source URL, or leave them blank to disable autodetection. --config convert.svn.branches=branches (directory name) specify the directory containing branches --config convert.svn.tags=tags (directory name) specify the directory containing tags --config convert.svn.trunk=trunk (directory name) specify the name of the trunk branch Source history can be retrieved starting at a specific revision, instead of being integrally converted. Only single branch conversions are supported. --config convert.svn.startrev=0 (svn revision number) specify start Subversion revision. Mercurial Destination --------------------- --config convert.hg.clonebranches=False (boolean) dispatch source branches in separate clones. --config convert.hg.tagsbranch=default (branch name) tag revisions branch name --config convert.hg.usebranchnames=True (boolean) preserve branch names options: -A --authors username mapping filename -d --dest-type destination repository type --filemap remap file names using contents of file -r --rev import up to target revision REV -s --source-type source repository type --splicemap splice synthesized history into place --datesort try to sort changesets by date use "hg -v help convert" to show global options adding a assuming destination a-hg initializing destination a-hg repository scanning source... sorting... converting... 4 a 3 b 2 c 1 d 0 e pulling from ../a searching for changes no changes found % should fail initializing destination bogusfile repository abort: cannot create new bundle repository % should fail abort: Permission denied: bogusdir % should succeed initializing destination bogusdir repository scanning source... sorting... converting... 4 a 3 b 2 c 1 d 0 e % test pre and post conversion actions run hg source pre-conversion action run hg sink pre-conversion action run hg sink post-conversion action run hg source post-conversion action
