Judy 2.4.2

PHP Judy implements sparse dynamic arrays (aka Judy Arrays)

PHP Judy implements sparse dynamic arrays (aka Judy Arrays). This extension is based
on the Judy C library. A Judy array consumes memory only when it is populated,
yet can grow to take advantage of all available memory if desired. Judy's key benefits
are scalability, high performance, and memory efficiency.

Changes

- SECURITY: fix use-after-free write on *_TO_MIXED overwrite/unset when a stored
value's destructor re-enters and mutates the same array (write-before-dtor /
delete-before-free)
- SECURITY: fix type confusion (UB) in getAll()/next()/rewind() for adaptive
types, which queried a JudyHS operation against the JudyL (SSO) store
- FIX: add get_gc handler so reference cycles through MIXED values are collectable
(previously leaked until request shutdown)
- FIX: STRING_TO_*_ADAPTIVE counter no longer double-counts when the value 0 is
re-stored (size/count/equals/averageValues were affected)
- FIX: $j[] = append after clone/fromArray/putAll no longer overwrites index 0
- FIX: first()/last()/searchNext()/prev() now work on adaptive types
- FIX: fromArray()/putAll() reject non-integer keys on integer-keyed types instead
of inserting at the string's hash
- FIX: __unserialize() on a populated object frees prior contents (no leak)
- FIX: forEach()/filter()/map() callbacks may re-enter without corrupting iteration
- FIX: equals() on INT_TO_PACKED no longer risks an infinite loop
- FIX: allocation failure (JERR) during write/unset is reported as failure, not success
- FIX: bulk operations stop on the first thrown key instead of continuing with a
pending exception; clone/slice no longer leak zvals or diverge on OOM paths
- FEATURE: set operations (intersect/diff/xor) now supported for STRING_TO_INT_ADAPTIVE
- BUILD: extension compiles warning-free; CI now fails on any new compiler warning
- BUILD: minimum PHP raised to 8.1 (PHP 8.0 is no longer tested in CI)
