From 20590343e5d712b7c9667bd129fdd6e3d1d1bf5f Mon Sep 17 00:00:00 2001 From: Jeff Jensen Date: Wed, 22 Jul 2026 19:23:33 -0500 Subject: [PATCH 01/40] fix(database): Attach tear-down failures as suppressed, not primary DatabaseTestCase.tearDown() run after a test body has already failed can throw its own exception, which (via normal Java finally/catch semantics in the caller) replaces the original test failure with no trace of it. This was reported in 2004 (SourceForge bugs#80, migrated as GitHub #141) and closed invalid at the time because it was considered unfixable given JUnit's lifecycle control at the time. Add an overload, tearDown(Throwable testFailure), for callers that already have a test failure in flight: a tear-down failure is attached to it via Throwable.addSuppressed() instead of replacing it, and the original testFailure is always what propagates. The existing no-arg tearDown() is unchanged; the shared operation-execution logic is factored into a private runTearDownOperation() helper. DatabaseTestCase implements InvocationInterceptor but overrides none of its methods, so it does not actually run setUp()/tearDown() automatically around @Test methods today; the real JUnit lifecycle wiring happens in subclasses like AbstractDatabaseIT via their own @BeforeEach/@AfterEach overrides. This fix targets the manual setUp()/tearDown() invocation path (as already used by DatabaseTestCaseIT's other test and by DefaultPrepAndExpectedTestCase) and leaves that unrelated, higher-risk interceptor question alone.

QuerySet.setId()/setRefid() still contain that validation, but Ant's attribute-binding no longer routes the id attribute through the task's setId() (id is a framework-reserved attribute consumed for project reference registration), so the refid-vs-id conflict check in setRefid() never sees a non-null id and never fires; the target now runs to completion. Rewrite the test to assert today's actual behavior (resolves the refid reference, does not throw) and rename to match, verified by running it against hsqldb.

From 5cb4ce40b308c6d5b005986ff4c447a4f88993f5 Mon Sep 17 00:00:00 2001 From: Jeff Jensen Date: Wed, 22 Jul 2026 23:54:47 -0500 Subject: [PATCH 06/40] feat(database): Add CachingConnectionProvider for cross-test connection reuse #461 asked for a DatabaseConnectionProvider to pool/cache connections across test methods, to avoid dbUnit re-fetching table metadata on every test. That was closed as not-planned: physical JDBC connection pooling is already solved by pointing DataSourceDatabaseTester at an external pool. But investigating it surfaced a narrower, real gap: dbUnit's own metadata cache (DatabaseDataSet, scoped to one IDatabaseConnection instance) is thrown away far more often than necessary, independent of physical pooling - every concrete IDatabaseTester builds a brand new IDatabaseConnection on every getConnection() call. Add CachingConnectionProvider, caching a single IDatabaseConnection (and therefore its metadata cache) across calls. A Callable supplies the connection-creation logic; it is only invoked on the first call and again whenever Connection#isValid() (or isClosed()) shows the previously cached connection is no longer alive, so a transient DB blip gets a transparent reconnect instead of silently reusing - or permanently failing on - a dead connection. Access is synchronized so concurrent callers cannot race each other into creating more than one connection, though the returned connection itself is not thread-safe for concurrent use. Wire it into JdbcDatabaseTester, DataSourceDatabaseTester, JndiDatabaseTester, PropertiesBasedJdbcDatabaseTester, and DefaultDatabaseTester via new, additive constructor overloads. Existing constructors are unchanged and remain the default (always-fresh) behavior; the new capability is entirely opt-in: share one CachingConnectionProvider instance across the tester instances built for each test method (e.g. a static field on a common test base class) to get reuse across a run, and pair it with IOperationListener#NO_OP_OPERATION_LISTENER (or an equivalent non-closing listener) - otherwise the default listener closes the connection after every onSetup()/onTearDown() call and the cache never has anything alive left to reuse. This makes the existing manual DefaultDatabaseTester + NO_OP_OPERATION_LISTENER reuse pattern - previously a dumb holder with no liveness check, documented only in the FAQ - safe to opt into without hand-wiring a static connection field. DatabaseTestCase/DBTestCase subclasses that only plug in an IDatabaseTester add no connection lifecycle logic of their own, so they benefit automatically by overriding newDatabaseTester() to pass a shared provider through. Update the FAQ's performance and keep-connection-open entries accordingly. Verified with new unit tests (real H2 in-memory connections, Mockito for the liveness-check edge cases, and a JDK-only InitialContextFactory test double for JndiDatabaseTester, since the project has no JNDI test dependency) and new integration tests against hsqldb, h2, derby, and postgresql (via Docker).

A new private ReusableConnectionDatabaseTester (extends AbstractDatabaseTester, backed by a Callable supplier, the same pattern CachingConnectionProvider already uses) lets onSetup()/onTearDown() run against that shared connection instead of each fetching their own. configureTest() remains self-contained - it still opens and closes its own connection - but now caches the resolved case-sensitivity flag so cleanupData() no longer needs a second connection just to re-read it. loadTableDataFromDatabase() switches to createDataSet().getTable() so verification reuses the connection's cached table metadata instead of re-deriving it from the ResultSet. Net effect: a full test lifecycle now uses 1-2 physical connections instead of 4-5. Update DefaultPrepAndExpectedTestCaseTest's close-count assertions to match, add a test proving verifyData() no longer calls the unimplemented-in-mock createTable(), and add a test that spies on the tester to prove getConnection() is called only twice across a full configureTest()+preTest()+postTest() cycle, including one with a non-default DELETE_ALL tear down operation. Simplify DefaultPrepAndExpectedTestCaseDiIT/ExtIT by removing the "databaseTesterNew2" reopen-connection workaround the tests previously needed between preTest() and postTest(); the reopen after configureTest() stays, since that method is still self-contained. Verified against all 9 supported databases: hsqldb, h2, derby, postgresql, mysql, mssql, db2, oracle-18, oracle-23.

Under a Turkish default locale, "ID".toLowerCase() yields the dotless-i "ıd" instead of "id", so an actual column that only differs in case from its expected counterpart (a common, otherwise-harmless mismatch dbunit is designed to tolerate here) fails to match, and verifyData() then reports a spurious missing-column difference instead of comparing the tables. Pin both toLowerCase() calls to Locale.ENGLISH, matching the same convention DatabaseDataSet.SchemaSet.normalizeSchema already uses for locale-independent case folding. Add testVerifyData_withTurkishDefaultLocale_matchesAsciiIColumns, which sets the JVM default to tr-TR (restored in a finally) and asserts verifyData() still matches an actual "ID" column against an expected, DataType.UNKNOWN "id" column.

Under a Turkish default locale, "id".toUpperCase() yields dotted "İD" instead of "ID", breaking table-name matching, filtering, and command parsing: * DbUnitAssertBase.getSortedTableNames() - table-name sorting for assertions * CaseInsensitiveDataSet - case-insensitive table lookup * LowerCaseDataSet / LowerCaseTableMetaData - lower-case dataset wrappers * PatternMatcher - include/exclude table name filtering * TablesDependencyHelper.normalizeToStoredCase() - dependency-search table name normalization * OracleConnection - schema name normalization * OracleSdoGeometryDataType - SDO_GEOMETRY string parsing * BytesDataType - "[file ...]"/"[base64 ...]" extended-syntax command parsing * TruncateTableOperation - DB2 product-name detection * AbstractTableMetaData.validateDataTypeFactory() - DB product validation warning Also stop DbUnitAssertBase.getSortedTableNames() from mutating the caller's array: operate on a clone, since IDataSet.getTableNames() does not guarantee a fresh copy per call. Add Turkish-locale regression tests for three representative sites (DbUnitAssertBaseTest, PatternMatcherTest, BytesDataTypeTest) plus a non-mutation test for getSortedTableNames().

FlatXmlWriter.row() only skipped null: a NO_VALUE cell reached DataType.asString(value), which returns null, and XmlWriter.writeAttribute() then threw NullPointerException. NO_VALUE cells are produced by XmlProducer for rows with fewer elements than columns and for explicit , so converting any such dataset to flat XML crashed. YamlWriter.dataSetAsMap() only checked value != null, so a NO_VALUE sentinel was put into the map and SnakeYAML dumped it as a useless !!java.lang.Object {} scalar instead of omitting the key. Extend both skip conditions to also treat NO_VALUE as "omit this attribute/key" - exactly flat XML's and YAML's existing representation of "no value".

Its sibling logDebugIfValueChanged was already internally consistent. The only caller is DatabaseConnection's schema-name correction notice, which previously never appeared at INFO. Change the inner call to logger.info(...) and update the JavaDoc's "(level DEBUG)" wording. New INFO-level output where none existed before - noted in changes.xml.

on Windows the file stayed locked until GC. toByteArray() also copied one byte at a time through the BufferedInputStream, which is needlessly slow for multi-megabyte BLOBs. toByteArray() already owns the stream lifecycle de facto, since every caller abandons the stream to it once called. Make that ownership explicit and enforced: wrap the buffered stream in try-with-resources, document the ownership transfer in the JavaDoc, and replace the per-byte loop with an 8KB chunk loop. loadFile(), loadURL(), and the typeCast() File/URL branches need no structural change - they already hand off a freshly-opened stream. Add testLoadFile_afterLoad_fileIsDeletable, which fails on Windows while the handle leaks, and testTypeCast_urlValue_closesStream, which verifies stream closure deterministically via a spy InputStream behind a custom URLStreamHandler (meaningful on any OS, including the Linux CI runners where an open file can still be deleted).

Now throws TypeCastException instead. (2) The [base64] branch returned Base64.decode(stringValue) unchecked; the vendored Base64.decode returns null for corrupt input, so an explicitly-tagged-as-base64 value that is corrupt silently became a NULL in the database. Now throws TypeCastException when decode() returns null. (3) The final "assume text content" fallback called stringValue.getBytes() with the platform default charset while its own comment (and the [text] branch's default) says UTF-8 - on Windows (cp1252) the stored bytes differed from Linux runs. Now uses StandardCharsets.UTF_8 explicitly. BEHAVIOR CHANGE: datasets that previously "worked" by silently inserting garbage/NULL now fail fast with a typed exception; the untagged-text fallback's bytes change on platforms whose default charset is not UTF-8. Both are corrections, not regressions. The untagged fallback chain's probe order (URL, then file, then base64, then text) is unchanged - out of scope per this plan.

Change the condition to "split > 0"; split == 0 (a leading dot) keeps the current unsplit behavior. A simple 2-part "A.TBL" name does not actually reach this code path: QualifiedTableName.parseFullTableName() already splits on the first dot before getEscapedName() ever runs, so a single-character schema alone never contains an embedded dot. The bug is only reachable via a 3+-part name whose second segment retains the dot after that first split (e.g. "CATALOG.X.TABLE" -> table field "X.TABLE"), which is where the added regression test targets it.

Use equalsIgnoreCase(FORMAT_CSV) at the dispatch site. Also validate the format is one of the recognized non-CSV formats before opening the FileOutputStream, instead of after, so an unsupported format (reachable only by bypassing the setFormat() setter) can no longer leave an empty file behind - this also covers any future format additions to the inner dispatch chain.

When both threw, the cleanup exception replaced the verify failure - that primary/shadow choice is deliberate (the user must know the database is in an unknown state) - but the verify failure was then completely lost, not attached anywhere. Every other dual-failure path in this class and its parents (its own runTest, closeReusableConnectionSuppressing, DatabaseTestCase.tearDown(Throwable)) preserves the secondary failure via Throwable.addSuppressed; this was the one remaining path that discarded one. Capture the verify failure as a Throwable (assertion failures from DefaultFailureHandler are Error subtypes, not Exception) and, only when cleanup subsequently fails too, attach it as suppressed on the cleanup exception before rethrowing. The cleanup exception remains primary exactly as before. An Error thrown by cleanupData() itself still replaces the verify failure without suppression - a narrow, accepted edge given Throwable.addSuppressed() is only reachable from the Exception catch clause here, consistent with cleanupData()'s own "throws Exception" contract.

Consequence: when a row with a real value in a NOT-NULL-with-default column was followed by a row with null in that column, the check reported "same shape", the old statement (which includes the column) was reused, and NULL was bound into a NOT NULL column - a constraint violation that appeared or disappeared depending on row order. Extract the shared predicate into one private static wouldIgnore() method used by both getIgnoreMapping() and equalsIgnoreMapping() so the two can never diverge again. Both methods keep their existing protected signatures. BEHAVIOR CHANGE: datasets that previously failed with a constraint violation now insert with the column's default - the documented intent of the getIgnoreMapping() rule. Statement churn increases slightly for alternating null/value patterns; that is correctness-required. Add a mock-based unit test verifying a second statement is created and that its SQL omits the defaulted column, plus an hsqldb-only IT (gated via Assumptions on the JDBC product name) exercising the real CLEAN_INSERT path against a NOT NULL DEFAULT column. The IT needed a new DEFAULT_VALUE_TABLE fixture in the HSQLDB DDL (dynamically creating/dropping the table mid-test hit IDatabaseConnection's per-connection table-list caching, which then shadowed the DROP for AbstractDatabaseIT's generic tearDown cleanup); the new fixture starts empty and is excluded from other tests' generic all-tables-are-prepopulated assumption via AbstractDataSetTest.removeExtraTestTables(), mirroring the existing IDENTITY_TABLE/TEST_IDENTITY_NOT_PK MSSQL-only exclusions. Also add the operation scope (used here for the first time) to CLAUDE.md's Commit Messages scope list, per the plan's instruction.

(2) escapeXml() iterated char-by-char, so a supplementary character (emoji, CJK-extension - valid XML, range 0x10000-0x10FFFF) was seen as two surrogate halves, each individually failing isValidXmlChar(), and was emitted as two numeric entities referencing forbidden surrogate code points - also a hard parse error on re-import. Rework escapeXml() to iterate by code point (String.codePointAt() / Character.charCount()) and check isValidXmlChar() first: a valid supplementary code point passes through raw (no markup character is outside the BMP); a valid BMP code point still routes through convertCharacterToEntity() unchanged, so existing subclass overrides keep taking effect; a code point that XML 1.0 cannot represent at all (control chars other than tab/LF/CR, 0xFFFE/0xFFFF, unpaired surrogates - isValidXmlChar() already correctly rejects all of these, it just was not being consulted for chars <= 0x7f or for supplementary code points) is substituted with U+FFFD and logged once per escapeXml() call, naming the replaced code points - never emitting them raw or as numeric entities, both of which are unparseable. convertCharacterToEntity() itself is untouched (signature and body), since escapeXml() now filters out-of-range code points before ever calling it. BEHAVIOR CHANGE: exports containing XML-unrepresentable control characters change from broken output to lossy-but-valid output with a warning; exports containing supplementary characters change from broken to correct.

Separately, if the offset subtraction drove the encoded value negative, divideAndRemainder(ONE_BILLION) yielded a negative remainder and ts.setNanos(negative) threw IllegalArgumentException. Replace the truncating division with Math.floorDiv(tsTime, 1000L) * 1000L. After divideAndRemainder, normalize a negative remainder by subtracting one from the quotient and adding ONE_BILLION to the remainder (standard floor-mod normalization) before constructing the Timestamp. Scope is pre-epoch timestamps with explicit timezone suffixes - currently wrong or crashing; post-epoch cases are unaffected since floorDiv and truncating division agree for non-negative values.

When an Error (e.g. AssertionError from a listener, OutOfMemoryError) propagated, the finally still ran setAutoCommit(true), which per JDBC commits the in-flight transaction - silently committing partial operation results and defeating the class's entire purpose. Add a fourth catch (Error e) alongside the three existing catches, rolling back and rethrowing exactly like its siblings. setAutoCommit(true) stays in the finally. Add a new Mockito-based TransactionOperationTest covering: an Error from the delegate rolls back without committing and rethrows unchanged; the success path commits then restores auto-commit, in that order, without ever rolling back; the pre-existing SQLException path still rolls back and rethrows. Additionally: the three pre-existing catch blocks (DatabaseUnitException, SQLException, RuntimeException) had the identical failure-masking bug this commit fixed for Error - each called rollback() unguarded, so a SQLException thrown by rollback() replaced the exception that triggered it instead of surfacing both. Extract a private static handleException(Connection, Throwable) helper that all four catch blocks now call: it attempts rollback and, if that itself throws SQLException, attaches the failure to the original exception via addSuppressed() instead of letting it replace it. This removes the duplicated try/catch that was previously inlined only in the Error block. Add regression tests mirroring the existing Error/rollback-failure case for DatabaseUnitException, SQLException, and RuntimeException: each asserts the original exception is still what's thrown and the rollback failure is attached as suppressed.

Clamp to Math.max(_sheet.getLastRowNum(), 0) so both header-only and truly-empty sheets report 0. (2) getValue() called _sheet.getRow(row + 1).getCell(...) directly; POI returns null for a physically-missing row (a gap row inside the sheet, e.g. after Sheet.removeRow()), producing a raw NullPointerException instead of treating the row's cells as empty, consistent with the existing cell == null -> null branch. Add three tests building POI workbooks in-memory: an empty sheet and a header-only sheet both report zero rows, and a sheet with a physically removed row returns null for that row's cells while still reading the row after the gap correctly.

On a platform whose default charset is not UTF-8 (e.g. Windows/cp1252), a YAML or DTD export containing non-ASCII text could not be re-read by dbUnit itself. OracleXMLTypeDataType.getSqlValue()/setSqlValue() have the same class of bug in their internal byte[]/String conversions (used for the Base64 representation dbUnit stores XMLTYPE content as): getBytes() and new String(bytes) both used the platform default charset with no explicit pairing between the two methods. Pinned both to UTF-8; the standard JDBC SQLXML.getString()/setString() calls that bracket these conversions already handle the actual XML document encoding safely and are unchanged. BEHAVIOR CHANGE: on a platform whose default charset is not UTF-8, the bytes written by these three writers change to what their readers already expect - a correction, not a regression. CSV read/write remains deliberately excluded: it is symmetric on one machine, so pinning UTF-8 there would break users whose existing fixture files are in the platform charset - a major-version change with a migration note, unlike these three writers whose current output is already broken cross-platform today. Add a YamlDataSet round-trip test for a non-ASCII value through a ByteArrayOutputStream/ByteArrayInputStream, and a FlatDtdDataSetIT test asserting the raw output bytes of a non-ASCII table name decode correctly as UTF-8.

The project version was bumped to 3.4.0-SNAPSHOT in 84c350d6, so that condition now holds; without enabling it, `mvn site` only regenerated the stale 3.2.0-to-3.3.0 comparison (of two already-released versions) and produced no report at all for this branch's actual changes, making the plan's end-of-Tier-2/end-of-plan japicmp checkpoints unable to check anything. Verified the resulting target/site/3.3.0-to-snapshot.html report: Access modifier filter is PROTECTED (public/protected surface only, matching this project's own compatibility policy), and every change across the whole report is METHOD_ADDED_TO_PUBLIC_CLASS - purely additive, non-breaking.

} } From b7be25f8ea43b269773e252b97db17cbf0982e49 Mon Sep 17 00:00:00 2001 From: Jeff Jensen Date: Mon, 27 Jul 2026 12:24:04 -0500 Subject: [PATCH 40/40] fix(ant): Include csv in Export.setFormat's unsupported-format message setFormat(String) has always accepted "csv" via isSupportedFormat(), but its IllegalArgumentException message listed only 'flat'(default), 'xml', 'dtd', 'xls', and 'yml' - omitting the one format this area's other bugs (issue 808) are specifically about, and misleading anyone who hit the exception into thinking csv wasn't supported.
