= Incoming =

== Open requests ==

Imports that need intervention from the vcs-imports operator.

== In progress ==

Imports being processed.

= Blocked =

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.

== [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 [[Date(2007-02-15T17:32:46Z)]]). 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.

== 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] svn_subst_translate_stream3

Imports that failed with the following error:

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

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.

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.

[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 Date(2007-02-15T17:32:46Z)). 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.

Anchor(squid)

[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.
