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. | ||||
|
r12924 | 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 | ||||
|
r12510 | 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 | ||||
|
r12787 | '''''''''''''''' | ||
|
r12510 | |||
|
r12922 | The Mercurial source recognizes the following configuration options, which | ||
you can set on the command line with "--config": | ||||
|
r12510 | |||
|
r12922 | 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. | ||||
|
r12510 | |||
CVS Source | ||||
|
r12787 | '''''''''' | ||
|
r12510 | |||
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 | ||||
|
r12924 | ":local:". The conversion uses the top level directory in the sandbox to | ||
|
r12510 | 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. | ||||
|
r12922 | The following options can be used with "--config": | ||
|
r12510 | |||
|
r12922 | 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. | ||||
|
r12510 | |||
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 | ||||
|
r12787 | ''''''''''''''''' | ||
|
r12510 | |||
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. | ||||
|
r12922 | The following options can be set with "--config": | ||
|
r12510 | |||
|
r12922 | convert.svn.branches | ||
specify the directory containing branches. The defaults is | ||||
|
r12924 | "branches". | ||
|
r12922 | convert.svn.tags | ||
|
r12924 | specify the directory containing tags. The default is "tags". | ||
|
r12922 | convert.svn.trunk | ||
|
r12924 | specify the name of the trunk branch The defauls is "trunk". | ||
|
r12510 | |||
Source history can be retrieved starting at a specific revision, instead | ||||
of being integrally converted. Only single branch conversions are | ||||
supported. | ||||
|
r12922 | convert.svn.startrev | ||
specify start Subversion revision number. The default is 0. | ||||
|
r12510 | |||
Perforce Source | ||||
|
r12787 | ''''''''''''''' | ||
|
r12510 | |||
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 | ||||
|
r12924 | directory, because otherwise the target may be named "...-hg". | ||
|
r12510 | |||
It is possible to limit the amount of source history to be converted by | ||||
|
r12922 | specifying an initial Perforce revision: | ||
|
r12510 | |||
|
r12922 | convert.p4.startrev | ||
specify initial Perforce revision, a Perforce changelist | ||||
number). | ||||
|
r12510 | |||
Mercurial Destination | ||||
|
r12787 | ''''''''''''''''''''' | ||
|
r12510 | |||
|
r12922 | The following options are supported: | ||
|
r12510 | |||
|
r12922 | 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 | ||||
|
r12510 | |||
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 | ||||
