[Monetdb-developers] other optimizer pipelines
by Wouter Alink 09 Apr '10

09 Apr '10

Dear M5 developers, Yesterday I reported a bug regarding the minimal optimizer pipe (ID: 2983773). And, as expected, I was asked to add a test for the issue, which I would like to do. The bug is triggered as follows: - start an mserver5 instance with the optimizer pipe set to the minimal pipe: "inline,remap,deadcode,multiplex" - connect with an mclient - connect again with an mclient This is obviously very easy to reproduce. But, I couldn't find any other test that sets a different optimizer upon startup of the mserver. I found a few tests that change the optimizer within a SQL script, but this will very likely not trigger bug (ID: 2983773). Then I was wondering; there are currently a few different optimizer pipelines defined in the monetdb5.conf. Isn't it a good idea to run at least a few (preferrably all) tests for each of those optimizer pipelines? I can imagine that testing all optimizer pipelines will take too much time for nightly testing, but running the testweb with different pipelines would probably trigger most obvious bugs that are currently found one-by-one. Bug #2983773 would most probably have been detected too. Anyway, I would like to add a test, and I guess testing multiple optimizer pipelines won't be high on the priority list. Therefore, could somebody perhaps point out how I could specify in the 'prologue' which optimizer pipeline to use? I did find a python file "sql/src/test/Connections/Tests/connections.py" which perhaps could be used? What is the preferred way for adding a test with a different optimizer path? Kind regards, Wouter

No need to add test for this. It is already included by several tests, e.g., WebSite/Tests/books1.xq WebSite/Tests/HelloWorld9.xq WebSite/Tests/books2.xq WebSite/Tests/slashdot2.xq WebSite/Tests/books3.xq WebSite/Tests/slashdot.xq WebSite/Tests/HelloWorldA.xq The testweb results (of the candidate branch) show that HelloWorld9.xq, HelloWorldA.xq and books1.xq fail with this error, *only* on Fedora10 G.64.64.d.0 Jennie > > > Index: pathfinder.mx > =================================================================== > RCS file: /cvsroot/monetdb/pathfinder/runtime/pathfinder.mx,v > retrieving revision 1.478.2.4 > retrieving revision 1.478.2.5 > diff -u -d -r1.478.2.4 -r1.478.2.5 > --- pathfinder.mx 29 Mar 2010 10:38:24 -0000 1.478.2.4 > +++ pathfinder.mx 9 Apr 2010 11:15:06 -0000 1.478.2.5 > @@ -3284,7 +3284,7 @@ > > # for not-yet-cached URIs: get lifetime from uri_lifetime BAT > var idx_idx := idx_doc.ord_uselect(oid_nil).mirror(); > - var idx_ts := idx_idx.leftfetchjoin(idx_filenames).ord_uselect(str_nil).mirror().leftfetchjoin(idx_timestamps); > + var idx_ts := idx_idx.leftfetchjoin(idx_filenames).ord_uselect(str_nil).mirror().leftfetchjoin(idx_timestamps).copy(); > idx_ts@batloop() { # URI (filename = nil) > var b := [startsWith](idx_names.find($h), mirror(uri_lifetime)).uselect(true); > var lifetime := lng_nil; > > > ------------------------------------------------------------------------------ > Download Intel® Parallel Studio Eval > Try the new software tools for yourself.
