php7-APCu-5.1.18-8.1

- Update to version 5.1.18
- Fixed compatibility with PHP 7.4 and PHP 8.0
- Implement apcu_inc() and apcu_dec() using atomic operations.
  This means that these functions no longer have to acquire a write lock.
  These functions will now wraparound on overflow,
  instead of saturating to a floating point value.
- Make table header in apc.php sticky.
- Fix compile warnings related to mktemp() usage.
- Fix compatibility with PHP 8.0.
- Fix required number of arguments for apcu_store() returned by Reflection.

- Build with php72 on Package Hub

- 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.

- updated to 5.1.11
  - fix gh#krakjoe/apcu#246 apcu_entry hangs
  - fix gh#krakjoe/apcu#259 deadlock in apcu_store
  - fix gh#krakjoe/apcu#281 undefined variable in apc.php
  - fix handling of fatal errors in apcu_entry
  - check string lengths when looking up keys
  - many internal C APIs changed
- updated to 5.1.10
  - fix gh#krakjoe/apcu#247 when a NUL char is used as key, apcu_fetch(array) truncates the key
  - fix gh#krakjoe/apcu#248 apcu_fetch may return values causing zend_mm_corruption or segfaults
    when custom serializer is used
  - fix gh#krakjoe/apcu#260 apcu.serializer=default results in segfault
  - fix gh#krakjoe/apcu#274 non-portable shell == in config.m4
  - fix crash when passing bad array to apcu_delete
  - improve fix gh#krakjoe/apcu#266 refcounting errors in APCIterator
  - fix for PHP 7.3 compatibility

- Build with -fvisibility=hidden, PHP process namespace
  pollution must be heavily limited to avoid symbol clashes.
- Use SOURCE_DATE_EPOCH if set instead of custom build hack.
- Update to version 5.1.9
- fix gh#234 mmap disabled when configure is called with --enable-apcu-mmap
- fix gh#226 Warning: apcu_fetch(): apc_fetch() expects a string or array of strings.
- mitigate gh#223 Fatal error when starting php on windows
- add support for PCRE2 in 7.3
- use row formatting for information in phpinfo() tables
- set IS_STR_PERSISTENT so refcounting failures are reported by -DRC_DEBUG=1
- fix gh#266 refcounting errors in APCIterator
