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.
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:
[https://launchpad.net/people/<launchpad-user> <launchpad-user>]: [https://launchpad.net/products/<launchpad-product>/<series> <product>/<series>] BR <location> BR @DATE@
Imports that need intervention from the vcs-imports operator.
Imports being processed.
Imports that are currently failing, and for which no fix is currently being worked on.
[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:

[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).

- The cscvs log (with changesets) first mentions epiphany-toolbar at changeset MAIN.67, it refers to revision 1.2 of this file and records it as a 'M' (modification), which fails to apply since the file is not present in the imported tree at this point.

[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.

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.
