This page tracks requests for actions from the vcs-imports operator.

To request an import, please:

  • Create a product in Launchpad and set the source details to the CVS or Subversion repository you wish to have imported. In particular
  • Add a request on this page, with the name of your launchpad account so I can find your email.

Note that we only do imports of MAIN branches on CVS (the form will have to be updated to remove the "branch" field) and trunk branches on Subversion.

We will handle your request and keep you informed of progress or issues. You can contact the vcs-imports operator: ddaa in #launchpad on irc.freenode.net.

Template to request an import:

Imports that need intervention from the vcs-imports operator.

In progress

Imports being processed.


Imports that are currently failing, and for which no fix is currently being worked on.

[svn] svn_subst_translate_stream3

Imports that failed with the following error:

python2.4: /build/buildd/subversion-1.3.1/subversion/libsvn_subr/subst.c:809: svn_subst_translate_stream3: Assertion `eol_str || keywords' failed.
process killed by signal 6

It looks like a problem in the svn code for keyword expansion.

[svn] wrong repository root

The current svn import code determines the root of the repository by walking up the URL until svn ls fails. This was necessary because older versions of libsvn_client did not expose the repository root information. Newer libsvn_client allow to determine this information directly. In cases where there are nested svn repositories, the old logic is wrong and that cause the change filtering (ignoring change outside of the branch being imported) to ignore legitimate changes.

[svn] unreliable server

The current svn import code makes many connections and does not retry when one fails. If the server is in the least unreliable (one failure every few thousand attempts to create a session) that will cause the import to fail.

It could be that some of these failures are caused by another specific bug. From a discussion with Jelmer:

> > >    * Don't rely on listdir() kind results. Fixes imports of several 
> > >      repositories. (#56647)
> > I'm curious about this bug. Can you tell me more?
> It turned out that the .kind member of dirents returned by
> svn.ra.get_dir2() is (semi-?)random when used against older Subversion
> servers. It would occasionally be 1 (svn.core.svn_node_file) even though
> the entry in question was a directory. This took me a while to track
> down. Instead, I've switched to always trying to open something as a
> directory and catching the appropriate exception that indicates it's a
> file.

That's very interesting. A number of Launchpad imports fail in a not-deterministic way with "failed REPORT". Currently I just classify those failures as "unreliable server", but I was puzzled by a pattern I noticed: the failures did not happen in a really random way.

It might be the same bug.

[svn] missing uri-encoding

cscvs uses the svn_client API to libsvn to retrieve data (on Date(2006-11-09T14:31:29Z)), but does not correctly uri-encode locations. So file names that contain characters that must be escaped cause import failures.

[cvs] failed to open the modules file

cscvs needs to read the modules file to ignore configs (aka externals, nested trees).

$ cvs -d :pserver:guest:guest@mozdev.org:/cvs co -c
cvs [checkout aborted]: failed to open the modules file

[svn] Cannot import whole repository

The svn import code fails at processing imports at the root of a svn repository. Some repository are set up that way, with the actual root containing the source code. That's broken, but people actually do this.


[cvs] None branch in findLastFileRevision

While creating changesets: assertion error, branchName is None in findLastFileRevision CVS/CacheGenerator.py:160

It looks like it means something is really busted with filler revisions and default branches.

[cvs] Absurd filler revision


  • nobody: [https://launchpad.net/products/xrms/trunk xrms/trunk] BR :pserver:anonymous@xrms.cvs.sourceforge.net:/cvsroot/xrms/ xrms BR [Date(2006-09-29T21:20:41Z)]

    • on changeset MAIN.4167: BR CRITICAL: requested checkout of reporoot '/cvsroot/xrms', file 'xrms/include/adodb/pear/Attic/readme.Auth.txt', revision '' BR CRITICAL: log of checkout responses follow. BR CRITICAL: "E cvs checkout: cannot find module BR `xrms/include/adodb/pear/Attic/readme.Auth.txt' - ignored\n" BR CRITICAL: 'error \n'

    • cscvs creates a filler changeset 1.1-> for include/adodb/pear/readme.Auth.txt, but there is no revision for that file. The cvs rlog shows revision 1.1 (branches: 1.1.1) used in changeset MAIN.915, revision, not used by cscvs. The cvs log header for that file reads "head: 1.1" and "branch: 1.1.1".

lifeless suggests:

(15:28:25) lifeless: I'd do a search in the file revision table for that file, all revisions, see what cscvs is thinking happened to it
(15:29:45) ddaa: you suggest it might be a problem in the log parser and checking the catalog contents would help narrowing the cause of the problem?
(15:33:11) lifeless: something is inventing the .2
(15:33:22) lifeless: if its in the catalog then the catalog generator can be checked
(15:33:42) lifeless: if its not in the catalog then the application-of-changesets can be checked
(15:33:45) lifeless: it will narrow it down
(15:34:03) lifeless: As its a very small rlog I'd make a test case from it

Failed to fork, memory error

Some large imports fail to os.fork() (when spawning gpg to sign a revision) with "OSError: [Errno 12] Cannot allocate memory". It's not clear why that happen, since Linux should overcommit memory up to 50x (the value of /proc/sys/vm/overcommit_ratio) and allow large processes like cscvs to spawn small processes like gpg.
