php7-APCu-5.1.15-2.1

- Updated to 5.1.15
  - Restore apc.serializer=php as the default, as the "default"
    serializer still/again has issues.
  - Fix possible issues in persistence of arrays with the "default"
    serializer.
  - Attempt to reduce shared memory fragementation.
- Updated to 5.1.14
  - Fixed GH #347: Disable slam defense by default.
  - Fix potential issue with destruction of locks. This does not
    affect Linux, but might affect Windows and BSD.
  - Use mutex instead of rwlock for shared memory allocator
    (if pthreads mutex available).
  - Require only read-lock for apcu_cas(), by using atomic
    compare-and-swap.
- Updated to 5.1.13
  - Reimplement persistence logic using precise allocation rather
    than memory pools. This reduces memory usage of cache entries,
    especially for small values, and improves performance of
    persisting and unpersisting values.
  - Fixed GH #335: Stampede protection is broken.
  - Fixed GH #328: Segfault in apcu_key_info() if APCu is disabled.
  - Generally make the behavior of functions if APCu is disabled
    more consistent.
  - Fixed PHP bug #72980: Empty strings are now consistently
    allowed as cache keys.
  - Optimized apcu_key_info() and apcu_cache_info() by using
    interned strings.
  - Fix build against PHP master (PHP 7.4).
  - Many changes to internal C APIs.

- Updated to 5.1.12
- gh#307: Fix 'Timout' sort option (apc.php).
- gh#308: Keep search parameter on cache entry detail link (apc.php).
- Fix --enable-apcu-clear-signal support.
- Show entries with expired global TTL in APCuIterator.
- Respect TTL when calculating APCuIterator totals.
- The per-entry TTL now always takes precedence over the global TTL.
- The global TTL is now always relative to the access time.
- apcu_inc() and apcu_dec() no longer update hard-expired entries. Instead a new entry is created.
- Added optional $ttl argument to apcu_inc() and apcu_dec(), used when creating a new entry.
- PHP bug #76145: Fix use of APCu inside Serializer::(un)serialize().
- gh#304: If apcu_cas() is used on a non-existing entry, don't insert it.
- gh#295: Improve APCuIterator performance by using PCRE JIT and preallocating key strings.
- Reduce the memory overhead of cache entries.
- Prevent potential memory corruption in the cache slam defense implementation.
- Ensure cache entry references are released on bailout during unserialization.
- Make support for atomic operations a hard requirement for building APCu.
- Check write-lock acquisition for failure, to help debugging deadlock situations.
- Make sure apcu_inc/dec are atomic when working on a non-existing entry.
- Many changes to internal C APIs.
