On some glibc implementations strncmp is a macro. This commit simply creates a
`redis_strncmp` static inline wrapper function so we can `ZEND_STRL` instead of
manually counting the length or using `sizeof(s)-1` each time.
Fixes#2565
* Add compression support for PHP Sessions
Previously, compression was available for standard data but not for
session handling. This update enables the compression of PHP sessions,
allowing for more efficient Redis memory usage.
* Move session compress/uncompress logic to helper functions
* Change session_compress_data to always set the out arguments and adjust PS_READ_FUNC
Previously, the redis.session.early_refresh feature was implemented for
Redis Cluster, utilizing GETEX for the initial session read to minimize
the number of commands sent to the Redis server. However, this enhancement
was not applied to non-cluster sessions. This update addresses this
discrepancy, ensuring consistent behavior between Redis and Redis Cluster.
* fix bug: the pipeline mode socket return an unexpected result after reconnecting
* fix typos: pipeline is right

* Add ini setting redis.session.early_refresh to allow for session TTL updates on session start ( requires redis server version 6.2 or greater )
* Enable cluster session support for strict mode sessions ( via PS_VALIDATE_SID_FUNC )
* Cluster sessions used to write on every session, now we only write if the session has been modified.
* Send EXPIRE instead of SETEX if sessioh has not been changed
* If early refresh is enabled use GETEX for initial session read
* When strict sessions are enabled, check whether the session exists first, validate sid and regenerate if necessary
Add support for Redis 6 ACLs in the `Redis`, `RedisCluster`, and `RedisArray` classes.
On a related note, it adds a mechanism for users to customize how we generate persistent connection IDs such that they can be grouped in different ways depending on the specific use case required (e.g. it would allow connections to be grouped by username, or by user-defined persistent_id, or both).
Various improvements and fixes to cluster slot caching.
* Improves slot caching so any unique set of seeds all hash to the same key
* Fix a couple of memory leaks.
* Fixes a segfault when executing a multiple key command such as `MGET` or `MSET` while the cluster is resharding.
This commit removes support for PHP 5 by getting rid of all of our Zend
compatibility layer methods, as well as any call checking against
PHP_MAJOR_VERSION or ZEND_MODULE_API_NO.
Unit tests are all passing for Redis, RedisCluster, and RedisArray but
this should still be considered a work in progress until more testing
can be done.
Addresses issue #1448
