13 repotool is a script wrapper around repository operations that differ
14 by version-control system. It is little use by itself, existing mainly
15 to generate and simplify a conversion makefile usable with
16 reposurgeon(1).
17 Not all actions are supported on all systems. You will get an error
19 message and a return value of 1 when attempting an unsupported action.
20 With -the -v option, report the commands executed just before they are
22 run.
23 The "initialize" option takes a project name (and, optionally,
25 following source and target VCS types) and generates a Makefile that
26 will sequence various steps of a repository conversion. It also
27 generates stub lift and options files. This is meant to be run in an
28 empty work directory, and it is an error to do 'initialize' where any
29 of these files already exist. Afterwards, you will need to set some
30 variables in the Makefile; read its header comment.
31 The 'export' action, run from within a repository directory, dumps a
33 copy of a CVS, Subversion, git, bzr, hg, or darcs repository to a flat
34 history file readable by reposurgeon. The format is usually a
35 git-fast-import stream, except that Subversion repositories export as
36 Subversion dump files; the point is to be a lossless erepresentation,
37 or as close to one as possible.
38 The 'tags' option, run from within a repository directory, returns a
40 list of the repository's release tags.
41 The 'branches' option, run from within a repository directory , returns
43 a list of the repository's branch names.
44 The 'checkout' option checks out a working copy of the repository. It
46 must be called from within the repository. It takes one required
47 argument - the checkout directory location.
48 The checkout option may take a revision, tag, or branch specifaction,
50 given with the -r, -t, or -b options. If the spec is omitted, the tip
51 of the main line of the repository will be used; this is equivalent to
52 specifying branch 'master' (git terminology, which is translated by
53 reposurgeon to 'trunk' or whatever the underlying VCS uses).
54 The 'compare' action takes two repository directories. It may
56 optionally take a tag-branch-revision spec as for the checkout option.
57 The selected versions are compared with diff -q -r, with noise due to
58 SCCS/RCS/CVS keyword expansion ignored. You can follow the command verb
59 with one or more -x options followed by basenames of paths to exclude
60 from comparison. You can get a context-diff report on file differences
61 with the -u option. File permissions well as content are checked, any
62 mismatches will be shown after the diff listing.
63 The 'compare-tags' action takes two repository directories, extracts a
65 list of tags from the first, then compares the repository contents at
66 each tag in the list, generating a compare report for each. You can
67 follow the command verb with one or more -x options followed by
68 basenames of paths to exclude from comparison. You can get a
69 context-diff report on file differences with the -u option.
70 The 'compare-branches' action takes two repository directories,
72 extracts a list of branches common to both, then compares the
73 repository contents at each branch in the list, generating a compare
74 report for each. You can follow the command verb with one or more -x
75 options followed by basenames of paths to exclude from comparison. You
76 can get a context-diff report on file differences with the -u option.
77 The 'compare-all' action takes two repository directories, and runs all
79 three above compare actions on them. Even if the same name is a tag in
80 one repository and a branch in the other, it will compare them against
81 each other. Not distinguishing them is useful as CVS tags that are not
82 applied to every file in the repository may get converted to branches.
83 The options are the same as 'compare-tags'.
84 The 'mirror' action makes or updates a local mirror of a Subversion,
86 CVS, git, or hg repo. It requires a single argument, either a
87 repository URL or the name of a local mirror directory created by a
88 previous run. The first form creates a local mirror of the repository
89 in a directory named after the last segment of the URL, with the suffix
90 “-mirror” (the local mirror name can be overridden by an optional
91 second argument). The second form updates the local mirror, doing an
92 incremental fetch; just give the mirror directory name.
93 Subversion URLs are as specified in the public documentation for
95 Subversion. CVS URLs must specify a host and repository path, followed
96 by a '#', followed by a module name. URLs for git and hg should be in
97 the form normally used for clone commands
98
100 This program uses the $TMPDIR environment variable, defaulting to /tmp
101 if it is not set.
102
104 Tag comparisons with git will not cope well with a branch name
105 containing the string "detached".
106 Due to extreme slowness of the Subversion checkout operation, the
108 compare head, tag, and branch modes assume that if one of the
109 direcvtories is a Subversion checkout you have done a full checkout of
110 HEAD before calling this tool; thus no svn update operation is required
111 unless you give an -r option. Spurious errors will be reported if the
112 directory is not a full checkout of HEAD. To avoid this optimization
113 and force updating, do "-r HEAD".
114
116 The export action is a wrapper around either native export facilities
117 or the following engines: cvs-fast-export(1) (for CVS), svnadmin(1)
118 (for SVN), hg-fast-export.py(1) (for hg). You must have the appropriate
119 engine in your $PATH for whatever kind of repository you are streaming.
