* Simple patch to prevent the common zero-width code points in our source and some types of resource files
* Validate correct UTF-8 input and fix buggy CSS file (ISO-8859-x encoded)
* add a bit of context
* Add CHANGES.txt
This commit reflows the code in the method body of computeCommonPrefixLengthAndBuildHistogram, so as to avoid a JVM JIT crash. The purpose of this change is to workaround the JVM bug which is somewhat fragile, but the best that we can do for now and appears to be working well.
* Rewrite Javascript expression compiler to use hidden classes and MethodHandles for functions
* Use dynamic constants for MethodHandles
* Remove invokestatic code and handle everything through dynamic constants
* Rewrite code to patch stack trace (keep Expressions class unmodified)
* Improve generating of constant names
* Remove classloader test (no longer needed)
* Add benchmark
* use better exception in benchmark
* Add documentation, migration guide and a utility method to convert legacy function maps
* also ignore SecurityException here while checking compatibility (if it happens only an imprecise error message is thrown)
* Use Map.copyOf to not clone the map each time we compile an expression
* Add another test with same method multiple times
* Update ASM to 9.6 and set classfile version to Java 17
* Cleanup classloader permissions, unfortunately "createClassLoader" is still needed for Jacoco for God knows what
* Change Postings back to using FOR in Lucene99PostingsFormat
We are still keeping PFOR for positions only.
This is a partial revert of https://github.com/apache/lucene/pull/69 which brings back ForDeltaUtil.
* fix merge commit
* Add forgotten forDeltaUtil calls to reader
* Addressing comments: adding Lucene90RWPostingsFormat + more
Also:
* Change to Changes.txt
* Removal of dead code which was only used in unit tests
* Removal of test code from PForUtil
* Changes.txt edit in right place now
* Apply suggestions from code review: `90 -> 99 refactoring`

* Remove decodeTo32 from ForUtil and regenerate

The default tests.multiplier passed from gradle was 1, but
LuceneTestCase tried to compute its default value from TESTS_NIGHTLY.
This could lead to subtle errors: nightly mode failures would not report
tests.multipler=1 and when started from the IDE, the tests.multiplier
would be set to 2 (leading to different randomness).

This commit enables the Panama Vector API for Java 21. The version of
VectorUtilPanamaProvider for Java 21 is identical to that of Java 20.
As such, there is no specific 21 version - the Java 20 version will be
loaded from the MRJAR.
Leverage accelerated vector hardware instructions in Vector Search.
Lucene already has a mechanism that enables the use of non-final JDK APIs, currently used for the Previewing Pamana Foreign API. This change expands this mechanism to include the Incubating Pamana Vector API. When the jdk.incubator.vector module is present at run time the Panamaized version of the low-level primitives used by Vector Search is enabled. If not present, the default scalar version of these low-level primitives is used (as it was previously).
Currently, we're only targeting support for JDK 20. A subsequent PR should evaluate JDK 21.
