Changes docstrings to begin with a lowercase word. Only docstrings used in help output is changed. Scripts are not expected to grep the output of 'hg help' so this change should pose no problem with regard to the compatibility rules.

hg convert [OPTION]... SOURCE [DEST [REVMAP]]
|
|
|
|
convert a foreign SCM repository to a Mercurial one.
|
|
|
|
Accepted source formats [identifiers]:
|
|
- Mercurial [hg]
|
|
- CVS [cvs]
|
|
- Darcs [darcs]
|
|
- git [git]
|
|
- Subversion [svn]
|
|
- Monotone [mtn]
|
|
- GNU Arch [gnuarch]
|
|
- Bazaar [bzr]
|
|
|
|
Accepted destination formats [identifiers]:
|
|
- Mercurial [hg]
|
|
- Subversion [svn] (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 <REVMAP> isn't given, it will be put in a default location
|
|
(<dest>/.hg/shamap by default). The <REVMAP> is a simple text
|
|
file that maps each source commit ID to the destination ID for
|
|
that revision, like so:
|
|
<source ID> <destination ID>
|
|
|
|
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.ignoreerrors=False (boolean)
|
|
ignore integrity errors when reading. Use it to fix Mercurial
|
|
repositories with missing revlogs, by converting from and to
|
|
Mercurial.
|
|
--config convert.hg.saverev=True (boolean)
|
|
allow target to preserve source revision ID
|
|
--config convert.hg.startrev=0 (hg revision identifier)
|
|
convert start revision and its descendants
|
|
|
|
CVS Source
|
|
----------
|
|
|
|
CVS source will use a sandbox (i.e. a checked-out copy) from CVS
|
|
to indicate the starting point of what will be converted. Direct
|
|
access to the repository files is not needed, unless of course
|
|
the repository is :local:. The conversion uses the top level
|
|
directory in the sandbox to find the CVS repository, and then uses
|
|
CVS rlog commands to find files to convert. This means that unless
|
|
a filemap is given, all files under the starting directory will be
|
|
converted, and that any directory reorganisation in the CVS
|
|
sandbox is ignored.
|
|
|
|
Because CVS does not have changesets, it is necessary to collect
|
|
individual commits to CVS and merge them into changesets. CVS
|
|
source uses its internal changeset merging code by default but can
|
|
be configured to call the external 'cvsps' program by setting:
|
|
--config convert.cvsps='cvsps -A -u --cvs-direct -q'
|
|
This is a legacy option and may be removed in future.
|
|
|
|
The options shown are the defaults.
|
|
|
|
Internal cvsps is selected by setting
|
|
--config convert.cvsps=builtin
|
|
and has a few more configurable options:
|
|
--config convert.cvsps.fuzz=60 (integer)
|
|
Specify the maximum time (in seconds) that is allowed between
|
|
commits with identical user and log message in a single
|
|
changeset. When very large files were checked in as part
|
|
of a changeset then the default may not be long enough.
|
|
--config convert.cvsps.mergeto='{{mergetobranch ([-\w]+)}}'
|
|
Specify a regular expression to which commit log messages are
|
|
matched. If a match occurs, then the conversion process will
|
|
insert a dummy revision merging the branch on which this log
|
|
message occurs to the branch indicated in the regex.
|
|
--config convert.cvsps.mergefrom='{{mergefrombranch ([-\w]+)}}'
|
|
Specify a regular expression to which commit log messages are
|
|
matched. If a match occurs, then the conversion process will
|
|
add the most recent revision on the branch indicated in the
|
|
regex as the second parent of the changeset.
|
|
|
|
The hgext/convert/cvsps wrapper script allows the builtin changeset
|
|
merging code to be run without doing a conversion. Its parameters and
|
|
output are similar to that of cvsps 2.1.
|
|
|
|
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
