color: add additional changeset.phase label to log.changeset and log.parent
This allows the user to set different colors for each phase, e.g.
[color]
changeset.public = blue
changeset.draft = green
changeset.secret = red
In addition, this doesn't affect current configuration for custom log.changeset
colors, but rather adds the option for users that want to visually see which
changesets are amendable.

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 (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, 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 a 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 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
-A --authormap FILE remap usernames using this file
--filemap FILE remap file names using contents of file
--splicemap FILE splice synthesized history into place
--branchmap FILE change branch names while converting
--branchsort try to sort changesets by branches
--datesort try to sort changesets by date
--sourcesort preserve source changesets order
