9 hg convert [OPTION]... SOURCE [DEST [REVMAP]]
10
11 convert a foreign SCM repository to a Mercurial one.
12
13 Accepted source formats [identifiers]:
14
15 - Mercurial [hg]
16 - CVS [cvs]
17 - Darcs [darcs]
18 - git [git]
19 - Subversion [svn]
20 - Monotone [mtn]
21 - GNU Arch [gnuarch]
22 - Bazaar [bzr]
23 - Perforce [p4]
24
25 Accepted destination formats [identifiers]:
26
27 - Mercurial [hg]
28 - Subversion [svn] (history on branches is not preserved)
29
30 If no revision is given, all revisions will be converted. Otherwise,
31 convert will only import up to the named revision (given in a format
32 understood by the source).
33
34 If no destination directory name is specified, it defaults to the basename
35 of the source with "-hg" appended. If the destination repository doesn't
36 exist, it will be created.
37
38 By default, all sources except Mercurial will use --branchsort. Mercurial
39 uses --sourcesort to preserve original revision numbers order. Sort modes
40 have the following effects:
41
42 --branchsort convert from parent to child revision when possible, which
43 means branches are usually converted one after the other. It
44 generates more compact repositories.
45 --datesort sort revisions by date. Converted repositories have good-
46 looking changelogs but are often an order of magnitude
47 larger than the same ones generated by --branchsort.
48 --sourcesort try to preserve source revisions order, only supported by
49 Mercurial sources.
50
51 If <REVMAP> isn't given, it will be put in a default location
52 (<dest>/.hg/shamap by default). The <REVMAP> is a simple text file that
53 maps each source commit ID to the destination ID for that revision, like
54 so:
55
56 <source ID> <destination ID>
57
58 If the file doesn't exist, it's automatically created. It's updated on
59 each commit copied, so "hg convert" can be interrupted and can be run
60 repeatedly to copy new commits.
61
62 The authormap is a simple text file that maps each source commit author to
63 a destination commit author. It is handy for source SCMs that use unix
64 logins to identify authors (eg: CVS). One line per author mapping and the
65 line format is:
66
67 source author = destination author
68
69 Empty lines and lines starting with a "#" are ignored.
70
71 The filemap is a file that allows filtering and remapping of files and
72 directories. Each line can contain one of the following directives:
73
74 include path/to/file-or-dir
75
76 exclude path/to/file-or-dir
77
78 rename path/to/source path/to/destination
79
80 Comment lines start with "#". A specified path matches if it equals the
81 full relative name of a file or one of its parent directories. The
82 "include" or "exclude" directive with the longest matching path applies,
83 so line order does not matter.
84
85 The "include" directive causes a file, or all files under a directory, to
86 be included in the destination repository, and the exclusion of all other
87 files and directories not explicitly included. The "exclude" directive
88 causes files or directories to be omitted. The "rename" directive renames
89 a file or directory if it is converted. To rename from a subdirectory into
90 the root of the repository, use "." as the path to rename to.
91
92 The splicemap is a file that allows insertion of synthetic history,
93 letting you specify the parents of a revision. This is useful if you want
94 to e.g. give a Subversion merge two parents, or graft two disconnected
95 series of history together. Each entry contains a key, followed by a
96 space, followed by one or two comma-separated values:
97
98 key parent1, parent2
99
100 The key is the revision ID in the source revision control system whose
101 parents should be modified (same format as a key in .hg/shamap). The
102 values are the revision IDs (in either the source or destination revision
103 control system) that should be used as the new parents for that node. For
104 example, if you have merged "release-1.0" into "trunk", then you should
105 specify the revision on "trunk" as the first parent and the one on the
106 "release-1.0" branch as the second.
107
108 The branchmap is a file that allows you to rename a branch when it is
109 being brought in from whatever external repository. When used in
110 conjunction with a splicemap, it allows for a powerful combination to help
111 fix even the most badly mismanaged repositories and turn them into nicely
112 structured Mercurial repositories. The branchmap contains lines of the
113 form:
114
115 original_branch_name new_branch_name
116
117 where "original_branch_name" is the name of the branch in the source
118 repository, and "new_branch_name" is the name of the branch is the
119 destination repository. No whitespace is allowed in the branch names. This
120 can be used to (for instance) move code in one repository from "default"
121 to a named branch.
122
123 Mercurial Source
124 ----------------
125
126 --config convert.hg.ignoreerrors=False (boolean)
127 ignore integrity errors when reading. Use it to fix Mercurial
128 repositories with missing revlogs, by converting from and to
129 Mercurial.
130
131 --config convert.hg.saverev=False (boolean)
132 store original revision ID in changeset (forces target IDs to change)
133
134 --config convert.hg.startrev=0 (hg revision identifier)
135 convert start revision and its descendants
136
137 CVS Source
138 ----------
139
140 CVS source will use a sandbox (i.e. a checked-out copy) from CVS to
141 indicate the starting point of what will be converted. Direct access to
142 the repository files is not needed, unless of course the repository is
143 :local:. The conversion uses the top level directory in the sandbox to
144 find the CVS repository, and then uses CVS rlog commands to find files to
145 convert. This means that unless a filemap is given, all files under the
146 starting directory will be converted, and that any directory
147 reorganization in the CVS sandbox is ignored.
148
149 The options shown are the defaults.
150
151 --config convert.cvsps.cache=True (boolean)
152 Set to False to disable remote log caching, for testing and debugging
153 purposes.
154
155 --config convert.cvsps.fuzz=60 (integer)
156 Specify the maximum time (in seconds) that is allowed between commits
157 with identical user and log message in a single changeset. When very
158 large files were checked in as part of a changeset then the default
159 may not be long enough.
160
161 --config convert.cvsps.mergeto='{{mergetobranch ([-\w]+)}}'
162 Specify a regular expression to which commit log messages are matched.
163 If a match occurs, then the conversion process will insert a dummy
164 revision merging the branch on which this log message occurs to the
165 branch indicated in the regex.
166
167 --config convert.cvsps.mergefrom='{{mergefrombranch ([-\w]+)}}'
168 Specify a regular expression to which commit log messages are matched.
169 If a match occurs, then the conversion process will add the most
170 recent revision on the branch indicated in the regex as the second
171 parent of the changeset.
172
173 --config hook.cvslog
174 Specify a Python function to be called at the end of gathering the CVS
175 log. The function is passed a list with the log entries, and can
176 modify the entries in-place, or add or delete them.
177
178 --config hook.cvschangesets
179 Specify a Python function to be called after the changesets are
180 calculated from the the CVS log. The function is passed a list with
181 the changeset entries, and can modify the changesets in-place, or add
182 or delete them.
183
184 An additional "debugcvsps" Mercurial command allows the builtin changeset
185 merging code to be run without doing a conversion. Its parameters and
186 output are similar to that of cvsps 2.1. Please see the command help for
187 more details.
188
189 Subversion Source
190 -----------------
191
192 Subversion source detects classical trunk/branches/tags layouts. By
193 default, the supplied "svn://repo/path/" source URL is converted as a
194 single branch. If "svn://repo/path/trunk" exists it replaces the default
195 branch. If "svn://repo/path/branches" exists, its subdirectories are
196 listed as possible branches. If "svn://repo/path/tags" exists, it is
197 looked for tags referencing converted branches. Default "trunk",
198 "branches" and "tags" values can be overridden with following options. Set
199 them to paths relative to the source URL, or leave them blank to disable
200 auto detection.
201
202 --config convert.svn.branches=branches (directory name)
203 specify the directory containing branches
204
205 --config convert.svn.tags=tags (directory name)
206 specify the directory containing tags
207
208 --config convert.svn.trunk=trunk (directory name)
209 specify the name of the trunk branch
210
211 Source history can be retrieved starting at a specific revision, instead
212 of being integrally converted. Only single branch conversions are
213 supported.
214
215 --config convert.svn.startrev=0 (svn revision number)
216 specify start Subversion revision.
217
218 Perforce Source
219 ---------------
220
221 The Perforce (P4) importer can be given a p4 depot path or a client
222 specification as source. It will convert all files in the source to a flat
223 Mercurial repository, ignoring labels, branches and integrations. Note
224 that when a depot path is given you then usually should specify a target
225 directory, because otherwise the target may be named ...-hg.
226
227 It is possible to limit the amount of source history to be converted by
228 specifying an initial Perforce revision.
229
230 --config convert.p4.startrev=0 (perforce changelist number)
231 specify initial Perforce revision.
232
233 Mercurial Destination
234 ---------------------
235
236 --config convert.hg.clonebranches=False (boolean)
237 dispatch source branches in separate clones.
238
239 --config convert.hg.tagsbranch=default (branch name)
240 tag revisions branch name
241
242 --config convert.hg.usebranchnames=True (boolean)
243 preserve branch names
244
245 options:
246
247 -s --source-type TYPE source repository type
248 -d --dest-type TYPE destination repository type
249 -r --rev REV import up to target revision REV
250 -A --authormap FILE remap usernames using this file
251 --filemap FILE remap file names using contents of file
252 --splicemap FILE splice synthesized history into place
253 --branchmap FILE change branch names while converting
254 --branchsort try to sort changesets by branches
255 --datesort try to sort changesets by date
256 --sourcesort preserve source changesets order
