_see #887, #902_ h3. h3(. -alternate OS approach- p(. p((. _tried, and problem also occurs on Mac, so using other approaches_ # -fix @`make install`@, which sets up the entire BIEN installation and dependencies- # -test the import on the local testing machine (a Mac), which already has most of the dependencies- # -if that doesn't work, try the other approaches below- h3. h3(. VM rollback approach p(. p((. _best approach because in theory, restoring to a working backup should allow us to successfully run the import_ # -restore vegbiendev to last working configuration- # -get restored VM to work on VirtualBox- ## -install bootloader- ## -install device drivers- _the Linux VM configuration does not support the VirtualBox ethernet device natively, so it must be configured manually_ # install database on VM # test import and verify that it works # perform system upgrades and see if import still works ** if not, selectively install system upgrades to narrow down the problem # update svn and see if import still works ** if not, test different revisions to narrow down the problem h3. h3(. -clean VM approach- p(. p((. _not using this approach due to complexity of obtaining/installing dependencies in the versions they had for the last successful import_ # -prepare clean VMs- # -fix @`make install`@, which sets up the entire BIEN installation and dependencies- ** normally, we do not reinstall the DB from scratch, so the bugs in @`make install`@ only become apparent when it is run on a partial installation # install the database from scratch on a clean VM (VirtualBox) ** this would involve adding any missing dependencies to our install scripts # test the import in the clean VM with a sample datasource to see if that reproduces the problem ** if it does, we know it's a bug in Postgres/Ubuntu and can troubleshoot using VM images with different Postgres/Ubuntu versions ** if it doesn't, it's a problem specific to just the vegbiendev VM and we would reset the vegbiendev VM to a clean Ubuntu install and reinstall our dependencies h3. h3(. Postgres rollback approach p(. p((. _not using this approach because it only works if the problem is with Postgres_ # roll back Postgres to the version it was at in the last successful import ** this may require building Postgres from source, because past _revisions_ of the same numeric version might only be available in version control, not in binary form via apt-get (which numbers packages by numeric version) ** if this isn't possible, it may be necessary to downgrade to Postgres 9.2 (which will unfortunately be missing some features that we now use) # see if this fixes the problem
