[Engine-devel] Switched to thread-based GWT worker factory
by Vojtech Szocs 07 Mar '14

07 Mar '14

Hi guys, with patch [1] merged into master, GWT compiler will now use only thread-based GWT worker factory (ThreadedPermutationWorkerFactory) when compiling WebAdmin & UserPortal GUI. [1] http://gerrit.ovirt.org/#/c/25163/ In practice, this means that GWT compiler will spawn up to: max_worker_threads = min(localWorkers, 4) when compiling specific permutations (i.e. browser x locale). Note that localWorkers value can be controlled through: EXTRA_BUILD_FLAGS="-Dgwt.compiler.localWorkers=..." DEV_EXTRA_BUILD_FLAGS="-Dgwt.compiler.localWorkers=..." Before this patch was merged, GWT compiler spawned up to: max_external_processes = localWorkers i.e. using separate Java sub-process (CompilePermsServer) that communicates with GWT compiler process via socket. For localWorkers == 1, tests show minimal-to-zero improvement. However, for localWorkers > 1, tests show a slight improvement in favor of thread-based approach. Let me know if you have any questions. Regards, Vojtech

[Engine-devel] Tweaking backup/restore of engine
by Sven Kieske 06 Mar '14

06 Mar '14

Hi, currently all events are stored in the table audit_log which all gets saved when you use the engine-backup shell script. the event log is full of these login lines (engine 3.3.2): 25652 fdfc627c-d875-11e0-90f0-83df133b58cc admin@internal 00000000-0000-0000-0000-000000000000 \N \N \N \N \N 2014-01-20 06:39:17.222+01 USER_VDC_LOGIN 30 0 User admin@internal logged in. f \N \N 00000000-0000-0000-0000-000000000000 \N \N \N \N 00000000-0000-0000-0000-000000000000 \N oVirt -1 30 f \N this makes the log and db grow very large when you use the REST-API to query ovirt for various data. Is this necessary for a working restore? It would be cool if we could tweak the engine-backup tool to just dump necessary tables so you don't have to restore events from the past no one is interested in. How does ovirt react, if I do not restore the content of the audit_log table? If this works (restore without audit_log) I would prefer to have this code upstream in ovirt git so I don't have to maintain my own backupscript. Would it be possible to extend the existing backupscript with a switch to not backup logs? Currently it's just "all" or "just db". I also recall that there shouldn't occur multiple login events any more since ovirt 3.3. but it still seems to be the case. I also do not understand how you would manage a stored authentication via REST as REST is stateless. I would appreciate any feedback or thoughts on this topic. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Engine-devel] Schema upgrade failure on master
by Adam Litke 05 Mar '14

05 Mar '14

Hi, I've recently rebased to master and it looks like the 03_05_0050_event_notification_methods.sql script is failing on schema upgrade. Is this a bug or am I doing something wrong? To upgrade I did the normal proceedure with my development installation: make install-dev ... ~/ovirt/bin/engine-setup Got this result in the log file: psql:/home/alitke/ovirt-**FILTERED**/share/ovirt-**FILTERED**/dbscripts/upgrade/03_05_0050_event_notification_methods.sql:10: ERROR: column "notification_method" contains null values FATAL: Cannot execute sql command: --file=/home/alitke/ovirt-**FILTERED**/share/ovirt-**FILTERED**/dbscripts/upgrade/03_05_0050_event_notification_methods.sql 2014-03-03 17:20:34 DEBUG otopi.context context._executeMethod:152 method exception Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/otopi/context.py", line 142, in _executeMethod method['method']() File "/home/alitke/ovirt-**FILTERED**/share/ovirt-**FILTERED**/setup/bin/../plugins/ovirt-**FILTERED**-setup/ovirt-**FILTERED**/db/schema.py", line 280, in _misc osetupcons.DBEnv.PGPASS_FILE File "/usr/lib/python2.7/site-packages/otopi/plugin.py", line 451, in execute command=args[0], RuntimeError: Command '/home/alitke/ovirt-**FILTERED**/share/ovirt-**FILTERED**/dbscripts/schema.sh' failed to execute -- Adam Litke

[Engine-devel] [ATN][devenv] update for otopi
by Alon Bar-Lev 05 Mar '14

05 Mar '14

Hello All, I would like to ask you to update your otopi package on your development machines to at least otopi-1.2.0_0.7. It is much closer to what we are going to release and will avoid many unrelated errors within log file due to a change in engine that soon to be applied. Please also notice that the nightly repository was modified recently and it is now changed place and was split here[1] and here[2], so it is a good opportunity to modify this as well in your /etc/yum.repo.d and have them both, dropping the old nightly. Thank you, Alon [1] http://resources.ovirt.org/pub/ovirt-snapshot/ [2] http://resources.ovirt.org/pub/ovirt-snapshot-static/
