dbUnit 3.3.0 Released

[jeffjensen]

This release reflects a strong focus on performance.

Feedback and bug reports are always welcome via GitHub Issues.

Fixed Bugs

• Restore execution of DepthFirstSearch tests that silently stopped running under JUnit Jupiter. Issue: 766. Thanks to jeffjensen.
• Enforce the search depth limit in DepthFirstSearch; direct-dependency lookups no longer include transitive tables. Issue: 766. Thanks to jeffjensen.
• Close result sets per iteration in PrimaryKeyFilter scans instead of leaking them. Issue: 767. Thanks to jeffjensen.
• Release workbook cell style cache entries after XLS write, fixing a memory leak. Issue: 768. Thanks to jeffjensen.
• Close the result set in SQLHelper.getPrimaryKeyColumn and raise a clear SQLException when the table has no primary key. Issue: 767. Thanks to jeffjensen.
• Close the internal file stream in the XlsDataSet(File) constructor instead of leaking it; buffer it while open. Issue: 788. Thanks to jeffjensen.
• Build the zero-padding format string in XlsDataSetWriter from the actual BigDecimal scale instead of substring-ing a fixed 52-character constant, which threw StringIndexOutOfBoundsException for scale greater than 52. Cap the padding length to avoid unbounded growth for a pathological scale, and deprecate the now-unused ZEROS constant. Issue: 790. Thanks to jeffjensen.
• Restore execution of 45 test methods across 22 classes that silently never ran under JUnit Jupiter: JUnit3-era overrides of inherited/abstract test methods and @Disabled-only methods missing the required @test annotation. Issue: 794. Thanks to jeffjensen.
• Fix corrupted expected-value string in HandlersTest.testEmptyQuotedAndUnquotedFieldsParser, exposed once the test began executing. Issue: 794. Thanks to jeffjensen.

• Release each CSV row read by CsvProducer as soon as it is handed to the dataset consumer, instead of retaining the full parsed file in memory alongside the CachedDataSet being built from it. Issue: 783. Thanks to jeffjensen.
• Replace the linear scan in OrderedTableNameMap.getOriginalTableName with a lookup map populated at add() time. Issue: 784. Thanks to jeffjensen.
