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]
|
|
|
- Perforce [p4]
|
|
|
|
|
|
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.
|
|
|
|
|
|
By default, all sources except Mercurial will use --branchsort. Mercurial
|
|
|
uses --sourcesort to preserve original revision numbers order. Sort modes
|
|
|
have the following effects:
|
|
|
|
|
|
--branchsort convert from parent to child revision when possible, which
|
|
|
means branches are usually converted one after the other.
|
|
|
It generates more compact repositories.
|
|
|
--datesort sort revisions by date. Converted repositories have good-
|
|
|
looking changelogs but are often an order of magnitude
|
|
|
larger than the same ones generated by --branchsort.
|
|
|
--sourcesort try to preserve source revisions order, only supported by
|
|
|
Mercurial sources.
|
|
|
|
|
|
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 "hg convert" can be interrupted and can be run
|
|
|
repeatedly to copy new commits.
|
|
|
|
|
|
The authormap 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:
|
|
|
|
|
|
source author = destination author
|
|
|
|
|
|
Empty lines and lines starting with a "#" are ignored.
|
|
|
|
|
|
The filemap is a file that allows filtering and remapping of files and
|
|
|
directories. Each line can contain one of the following directives:
|
|
|
|
|
|
include path/to/file-or-dir
|
|
|
|
|
|
exclude path/to/file-or-dir
|
|
|
|
|
|
rename path/to/source path/to/destination
|
|
|
|
|
|
Comment lines start with "#". A specified path matches if it equals the
|
|
|
full relative name of a file or one of its parent directories. The
|
|
|
"include" or "exclude" directive with the longest matching path applies,
|
|
|
so line order does not matter.
|
|
|
|
|
|
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 directories not explicitly included. The "exclude" directive
|
|
|
causes files or directories to be omitted. The "rename" directive renames
|
|
|
a file or directory if it is converted. 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 comma-separated values:
|
|
|
|
|
|
key parent1, parent2
|
|
|
|
|
|
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. For
|
|
|
example, if you have merged "release-1.0" into "trunk", then you should
|
|
|
specify the revision on "trunk" as the first parent and the one on the
|
|
|
"release-1.0" branch as the second.
|
|
|
|
|
|
The branchmap is a file that allows you to rename a branch when it is
|
|
|
being brought in from whatever external repository. When used in
|
|
|
conjunction with a splicemap, it allows for a powerful combination to help
|
|
|
fix even the most badly mismanaged repositories and turn them into nicely
|
|
|
structured Mercurial repositories. The branchmap contains lines of the
|
|
|
form:
|
|
|
|
|
|
original_branch_name new_branch_name
|
|
|
|
|
|
where "original_branch_name" is the name of the branch in the source
|
|
|
repository, and "new_branch_name" is the name of the branch is the
|
|
|
destination repository. No whitespace is allowed in the branch names. This
|
|
|
can be used to (for instance) move code in one repository from "default"
|
|
|
to a named branch.
|
|
|
|
|
|
Mercurial Source
|
|
|
''''''''''''''''
|
|
|
|
|
|
The Mercurial source recognizes the following configuration options, which
|
|
|
you can set on the command line with "--config":
|
|
|
|
|
|
convert.hg.ignoreerrors
|
|
|
ignore integrity errors when reading. Use it to fix Mercurial
|
|
|
repositories with missing revlogs, by converting from and to
|
|
|
Mercurial. Default is False.
|
|
|
convert.hg.saverev
|
|
|
store original revision ID in changeset (forces target IDs to
|
|
|
change). It takes and boolean argument and defaults to False.
|
|
|
convert.hg.startrev
|
|
|
convert start revision and its descendants. It takes a hg
|
|
|
revision identifier and defaults to 0.
|
|
|
|
|
|
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
|
|
|
reorganization in the CVS sandbox is ignored.
|
|
|
|
|
|
The following options can be used with "--config":
|
|
|
|
|
|
convert.cvsps.cache
|
|
|
Set to False to disable remote log caching, for testing and
|
|
|
debugging purposes. Default is True.
|
|
|
convert.cvsps.fuzz
|
|
|
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. The default
|
|
|
is 60.
|
|
|
convert.cvsps.mergeto
|
|
|
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. Default
|
|
|
is "{{mergetobranch ([-\w]+)}}"
|
|
|
convert.cvsps.mergefrom
|
|
|
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. Default is
|
|
|
"{{mergefrombranch ([-\w]+)}}"
|
|
|
hook.cvslog
|
|
|
Specify a Python function to be called at the end of gathering
|
|
|
the CVS log. The function is passed a list with the log
|
|
|
entries, and can modify the entries in-place, or add or delete
|
|
|
them.
|
|
|
hook.cvschangesets
|
|
|
Specify a Python function to be called after the changesets
|
|
|
are calculated from the the CVS log. The function is passed a
|
|
|
list with the changeset entries, and can modify the changesets
|
|
|
in-place, or add or delete them.
|
|
|
|
|
|
An additional "debugcvsps" Mercurial command 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. Please see the command help for
|
|
|
more details.
|
|
|
|
|
|
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 overridden with following options. Set
|
|
|
them to paths relative to the source URL, or leave them blank to disable
|
|
|
auto detection.
|
|
|
|
|
|
The following options can be set with "--config":
|
|
|
|
|
|
convert.svn.branches
|
|
|
specify the directory containing branches. The default is
|
|
|
"branches".
|
|
|
convert.svn.tags
|
|
|
specify the directory containing tags. The default is "tags".
|
|
|
convert.svn.trunk
|
|
|
specify the name of the trunk branch. The default is "trunk".
|
|
|
|
|
|
Source history can be retrieved starting at a specific revision, instead
|
|
|
of being integrally converted. Only single branch conversions are
|
|
|
supported.
|
|
|
|
|
|
convert.svn.startrev
|
|
|
specify start Subversion revision number. The default is 0.
|
|
|
|
|
|
Perforce Source
|
|
|
'''''''''''''''
|
|
|
|
|
|
The Perforce (P4) importer can be given a p4 depot path or a client
|
|
|
specification as source. It will convert all files in the source to a flat
|
|
|
Mercurial repository, ignoring labels, branches and integrations. Note
|
|
|
that when a depot path is given you then usually should specify a target
|
|
|
directory, because otherwise the target may be named "...-hg".
|
|
|
|
|
|
It is possible to limit the amount of source history to be converted by
|
|
|
specifying an initial Perforce revision:
|
|
|
|
|
|
convert.p4.startrev
|
|
|
specify initial Perforce revision (a Perforce changelist
|
|
|
number).
|
|
|
|
|
|
Mercurial Destination
|
|
|
'''''''''''''''''''''
|
|
|
|
|
|
The following options are supported:
|
|
|
|
|
|
convert.hg.clonebranches
|
|
|
dispatch source branches in separate clones. The default is
|
|
|
False.
|
|
|
convert.hg.tagsbranch
|
|
|
branch name for tag revisions, defaults to "default".
|
|
|
convert.hg.usebranchnames
|
|
|
preserve branch names. The default is True.
|
|
|
|
|
|
options:
|
|
|
|
|
|
-s --source-type TYPE source repository type
|
|
|
-d --dest-type TYPE destination repository type
|
|
|
-r --rev REV import up to target revision REV
