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.
--closesort try to move closed revisions as close as possible
to parent branches, 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 (e.g.: 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. The default
if there are no ``include`` statements is to include everything.
If there are any ``include`` statements, nothing else is 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.
``--full`` will make sure the converted changesets contain exactly
the right files with the right content. It will make a full
conversion of all files, not just the ones that have
changed. Files that already are correct will not be changed. This
can be used to apply filemap changes when converting
incrementally. This is currently only supported for Mercurial and
Subversion.
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 a boolean argument and
defaults to False.
:convert.hg.revs: revset specifying the source revisions to convert.
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]+)}}``
:convert.localtimezone: use local time (as determined by the TZ
environment variable) for changeset date/times. The default
is False (use UTC).
:hooks.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.
:hooks.cvschangesets: Specify a Python function to be called after
the changesets are calculated from 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``.
:convert.localtimezone: use local time (as determined by the TZ
environment variable) for changeset date/times. The default
is False (use UTC).
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.
Git Source
##########
The Git importer converts commits from all reachable branches (refs
in refs/heads) and remotes (refs in refs/remotes) to Mercurial.
Branches are converted to bookmarks with the same name, with the
leading 'refs/heads' stripped. Git submodules are converted to Git
subrepos in Mercurial.
The following options can be set with ``--config``:
:convert.git.similarity: specify how similar files modified in a
commit must be to be imported as renames or copies, as a
percentage between ``0`` (disabled) and ``100`` (files must be
identical). For example, ``90`` means that a delete/add pair will
be imported as a rename if more than 90% of the file hasn't
changed. The default is ``50``.
:convert.git.findcopiesharder: while detecting copies, look at all
files in the working copy instead of just changed ones. This
is very expensive for large projects, and is only effective when
``convert.git.similarity`` is greater than 0. The default is False.
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.

----------
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

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.
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 option is deprecated and will be removed in Mercurial 1.4.
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.cache=True (boolean)
Set to False to disable remote log caching, for testing and
debugging purposes.
--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

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. 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".
"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. This can be used to (for instance) move code
in one repository from "default" to a named branch.
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=False (boolean)
store original revision ID in changeset (forces target IDs to
change)
--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 reorganization in the CVS
sandbox is ignored.
The options shown are the defaults.
--config convert.cvsps.cache=True (boolean)
Set to False to disable remote log caching, for testing and
debugging purposes.
--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.
--config 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.
--config 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.
--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.
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.
--config convert.p4.startrev=0 (perforce changelist number)
specify initial Perforce 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

- 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.
--closesort try to move closed revisions as close as possible
to parent branches, 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 (e.g.: 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. The default
if there are no ``include`` statements is to include everything.
If there are any ``include`` statements, nothing else is 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.

conjunction with a splicemap, it allows for a powerful combination
to help fix even the most badly mismanaged repositories and turn them

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``:

converting from and to Mercurial. Default is False.
:convert.hg.saverev: store original revision ID in changeset
(forces target IDs to change). It takes a boolean argument and
defaults to False.
