This page tracks requests for actions from the vcs-imports operator. To request an import, please see the instructions on VcsImports.

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

We will handle your request and keep you informed of progress or issues. You can contact a vcs-imports operator on #launchpad on irc.libera.chat.

Note: There exists also https://dev.launchpad.net/ReviewingCodeImports, which is rather more up to date, and which this page should probably go away in favour of.

Imports that are currently failing: https://code.launchpad.net/+code-imports?field.review_status=FAILING

Number failing by type on 2011-04-08:

... from which we may conclude that CSCVS is A Problem :-)

[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] bogus repository root detection

Bug 156744.

[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.

See bug 120992 (use persistent svn_ra sessions and reconnect on failure).

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] pysvn._pysvn.ClientError: Connection closed unexpectedly

[svn] pysvn._pysvn.ClientError: Malformed network data

[svn] import stalls, or is too slow

The import system will kill any job that does produce output for "a long time" (4 hours, at time of writing, on 2007-02-15). So if, for some reason, an import does not report progress for a long time, either because it is stuck or because it is really slow, it will fail.

[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.

See bug 145240.

[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.

File name not supported by bzr

This is bzr bug #58180. When/if that gets fixed, all these could be retried.

[cvs] Absurd filler revision

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

[svn] svn:special with bad file content

http://ascendsvn.cheme.cmu.edu/ascend/code/trunk/pygtk/interface/config.guess@416 has svn:special set but contains real source, instead of special content.

Unknown failures

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.

[svn] mystery 403

It may be that the server has DOS protection, and thinks we're attacking it.

Problems with filename containing ..

The programmatic API for adding files to a tree has different expectations than the user friendly API the command line uses (bug 132639). Depending on how this bug gets resolved, the following import could be retried after it is fixed.

This means the server/repo is broken.
