Entry DumpEntry has no content for me to return while processing dump entry

[Peter Connolly]

In the process of working through bug #349329, encountered the following error when running the command:

sudo ~/bin/svn2bzr/svn2bzr.py svn-repos-dump-full_20090415-0130.edited /var/bzr

Peter, sorry for the delay. I'm not quite sure why this is happening. It seems that something's wrong with the "trunk/ZacksTool/doc/design/DbSchemaCreditCard.dia" path. Could you search for the first few occurrences of that node-path name in the dump file prior to Revision 607, and post the revisions in which they occur? Also, could you re-run the conversion with the "--log=debug" option and post everything printed to screen in a text file attachment?

[Martin Spacek (mspacek)]

Also, I posted rev 24 which should print slightly more informative error messages to debug this problem. Please try running that.

[Peter Connolly (peterc-alembixengineering)]

Adding revision 536. Had to zip it as it was rather large.

[Peter Connolly (peterc-alembixengineering)]

Adding revision 368.

[Peter Connolly (peterc-alembixengineering)]

Adding revision 313.

[Peter Connolly (peterc-alembixengineering)]

Adding final revision (#24) for DbSchemaCreditCard.dia.

[Peter Connolly (peterc-alembixengineering)]

Upgraded svn2bzr to rev 24 and re-ran the same command with the --log=debug option added:

sudo ~/bin/svn2bzr/svn2bzr.py --log=debug ~/tmp/svn-repos-dump-full_20081001-0130.edited /var/bzr &> svn2bzr-rev-24-output.txt

Interestingly, the 607 generates the same error but continues processing. Eventually the conversion fails while processing revision 994.

Attaching the complete console output.

[Peter Connolly (peterc-alembixengineering)]

Btw, would have replied sooner but was on a trip.

Peter, sorry for the long delay. Things have been hectic around here. It seems your dump file is triggering a problem I was having myself when I converted my own svn repos to bzr. I added a hack that worked for me (see get_entry_content at dump.py line 187). The hack didn't really solve the underlying problem, and now it's rearing its head again. So it looks like I'll have to solve it properly this time, which might take a while.
