Launchpad itself

SVN import from SourceForge fails every time

Asked by Mantas Kriaučiūnas

Hi launchpad developers,

I can't import an sourceforge svn repository of latest stable SuperTuxKart game release (0.7.3) into launchpad (https://code.launchpad.net/~stk/stk/0.7.3) since yesterday. Import fails every time with the following error msg:

See http://launchpadlibrarian.net/85324603/stk-stk-0.7.3.log and https://code.launchpad.net/~stk/stk/0.7.3 for more info.

I've tried both access methods - http and https, but both fails :(
Also I found more questions about same SVN import problems, see question #170639

Btw, 4 months ago SVN import of previous SuperTuxkart 0.7.2 release passed without problems, see https://code.launchpad.net/~stk/stk/0.7.2

Unfortunately this is SourceForge hanging up on us on Launchpad while it is doing the import.

One way to work around this would be for Launchpad to not import as many revisions at once, lowering the chance of connection issues. The most flexible solution would probably be to add a setting for imports that controls the batch size.

We can change the batch size of imports at the moment, but unfortunately this impacts all SVN imports - and would slow down new imports.

Hi Jelmer,

Maybe there is a way to import just last revision of
http://supertuxkart.svn.sourceforge.net/svnroot/supertuxkart/main/branches/0.7.3/

We don't need full history of commits in this branch, we need just
last code and, if this possible, a possibility to get new revisions from
http://supertuxkart.svn.sourceforge.net/svnroot/supertuxkart/main/branches/0.7.3/

Hello Jelmer and all launchpad developers,

Please tell use if there is a way to import just last revision of
http://supertuxkart.svn.sourceforge.net/svnroot/supertuxkart/main/branches/0.7.3/

We don't need full history of commits in this branch, we need just
last code and, if this possible, a possibility to get new revisions from
http://supertuxkart.svn.sourceforge.net/svnroot/supertuxkart/main/branches/0.7.3/

Please answer us, we are waiting for about a week for import of new SuperTuxKart version :(

jelmer told me in IRC #launchpad channel:
you could do the import yourself manually, and then push that to launchpad

ubuntu-baltix: jelmer, how I can import manually ?
jelmer: using bzr-svn, run "bzr init import"; "bzr pull -d import URL -r500"; "bzr pull -d import URL -r1000"; etc
ubuntu-baltix: can I import just last revision of http://supertuxkart.svn.sourceforge.net/svnroot/supertuxkart/main/branches/0.7.3/ ?
jelmer: you should be able to do that too, by just using "svn export" and then versioning that with bzr

ubuntu-baltix: if I import just last revision in this way, would it have a possibility to get new revisions from
http://supertuxkart.svn.sourceforge.net/svnroot/supertuxkart/main/branches/0.7.3/ with launchpad.net web interface?
jelmer: no, launchpad won't update the branch if you do a manual import
ubuntu-baltix: even if I import with bzr-svn commands "bzr init import"; "bzr pull -d import URL -r500"; etc ?
 jelmer: yes, launchpad doesn't import into user-managed branches

jelmer: we're going to change the batch size to 500 revisions, perhaps that will help

How did the manual import go?

I repeated the import of sourceforge svn repository when you changed batch size to 500 revisions and this time SuperTuxKart 0.7.3 code was imported successfully, see https://code.launchpad.net/~stk/stk/0.7.3
