Class Bug

java.lang.Object

mondrian.util.Bug

public class Bug
extends Object

Holder for constants which indicate whether particular issues have been fixed. Reference one of those constants in your code, and it is clear which code can be enabled when the bug is fixed. Generally a constant is removed when its bug is fixed.

Cleanup items

The following is a list of cleanup items. They are not bugs per se: functionality is not wrong, just the organization of the code. If they were bugs, they would be in jira. It makes sense to have the list here, so that referenced class, method and variable names show up as uses in code searches.

Obsolete Id.Segment

Replace it by IdentifierSegment. Likewise Id.Quoting with Quoting. Should wait until after the mondrian 4 'big bang', because there are ~300 uses of Segment in the code.

Field Details

Ssas2005Compatible

public static final boolean Ssas2005Compatible

Whether Mondrian is 100% compatible with Microsoft Analysis Services 2005. We know that it is not, so this constant is false.

Use this field to flag test cases whose behavior is intentionally different from SSAS. If the behavior is unintentionally different and something we want to fix, log a bug, add a new BugMondrianXxxFixed constant to this class, and make the test case conditional on that constant instead.

See also the property MondrianProperties.SsasCompatibleNaming, which allows the user to choose certain behaviors which are compatible with SSAS 2005 but incompatible with Mondrian's previous behavior.

Method Details

olap4jUpgrade

public static boolean olap4jUpgrade(String reason)

If you want to tag a piece of code in mondrian that needs to be changed when we upgrade to a future version of olap4j, reference this function. It will always return false.

avoidMemoryOverflow

public static boolean avoidMemoryOverflow(Dialect dialect)

Returns whether to avoid a test because the memory monitor may cause it to fail.

Some tests fail if memory monitor is switched on, and Access and Derby tend to use a lot of memory because they are embedded.

Parameters:

dialect - Dialect

Returns:

Whether to avoid a test

avoidSlowTestOnLucidDB

public static boolean avoidSlowTestOnLucidDB(Dialect dialect)

Returns true if we are running against Dialect.DatabaseProduct.LUCIDDB and we wish to avoid slow tests.

This is because some tests involving parent-child hierarchies are very slow. If we are running performance tests (indicated by the mondrian.test.PerforceTest logger set at org.apache.log4j.Level#DEBUG or higher), we expect the suite to take a long time, so we enable the tests.

Fixing either MONDRIAN-759 or FRG-400, "rewrite statements containing literals to use internally-managed dynamic parameters instead" would solve the problem.

Returns:

Whether we are running LucidDB and we wish to avoid slow tests.
