Aug 2011-SP1 bugfix release SQL * Fixed a bug when using default values for interval columns. Bug 2877. * A bug was fixed where deleted rows weren't properly accounted for in all operations. This was bug 2882. * A bug was fixed which caused an update to an internal table to happen too soon. The bug could be observed on a multicore system with a query INSERT INTO t (SELECT * FROM t) when the table t is "large enough". This was bug 2883. Client Package * Fixed Perl DBD rowcount for larger results, bug #2889 * Perl: We now distinguish properly between TABLE and GLOBAL TEMPORARY (the latter are recognized by being in the "tmp" schema). * Perl: fixed a bunch of syntax errors. This fixes bug 2884. With thanks to Rémy Chibois. * Perl: Fixed DBD::monetdb table_info and tabletype_info. This fixes bug 2885. With thanks to Rémy Chibois. * mclient: fix display of varchar columns with only NULL values. * Fixed a bug in mclient/msqldump where an internal error occurred during dump when there are GLOBAL TEMPORARY tables. MonetDB5 Server * Fixed a problem where MAL variables weren't properly cleared before reuse of the data strucutre. This problem could cause the data flow scheduler to generate dependencies between instructions that didn't actually exist, which in turn could cause circular dependencies among instructions with deadlock as a result. Bugs 2865 and 2888. Bug Fixes * 2865: mserver5 --set gdk_nr_threads=2 --forcemito: deadlock during first SQL client connect on virgin (empty) DB * 2877: assertion failed when creating table with default interval * 2879: A SELECT query fails to produce some results * 2882: Delete of some records don't work on Monetdb * 2883: insert into t (select * from t) bogus in multithreaded execution * 2884: Mapi.pm and GetInfo.pm syntax fixes for array usage * 2885: DBD::monetdb table_info error * 2887: Division by zero error, when should not divide at 0 * 2888: test/null/null_in_case.sql hangs server * 2889: Mapi::getBlock is erasing query count on second call
