This commit introduces support for the Redis SCAN, HSCAN, SSCAN,
and ZSCAN commands.
In the case of HSCAN, SSCAN, and ZSCAN, we take a key and iterator
as required arguments, and for SCAN just an iterator. Matching
the Redis commands, each variant can optionally take a pattern
to match against and a count value which hints at Redis how many
keys to return at a time.
When scanning keys or members (especially with a large keyspace when
searching for a pattern), Redis will sometimes return an empty result
of keys/members. PHPRedis can be set up to abstract this from the
caller by setting:
$redis->setOption(Redis::OPT_SCAN, Redis::SCAN_RETRY);
Which instructs PHPRedis to keep retrying the scan until members are
returned OR the iteration completes (Redis returns to us a zero iterator).
By default this option is set to Redis::SCAN_NORETRY, meaning that
empty results are possible, requiring an explicit check for FALSE in the
scanning loop, like so:
```php
$it = NULL;
while(($arr_keys = $redis->scan($it, "*pattern*"))!==FALSE) {
print_r($arr_keys);
}
```
This brings the W32 compilation fixes done by @char101 up to date and
allows building of php_redis.dll with VC11 on Win32 (allows for a php5.5
version).
Use the lengths for our optional parameters, as NULL will
come through as a non null zval pointer with a zero length
Properly return the length from the redis_cmd_sstr_init function
This commit changes how we build the Redis protocol string for
ZUNIONSTORE and ZINTERSTORE such that we avoid reallocating
memory for the command buffer for each new key or weight
This commit changes the way we construct the MGET command
such that we avoid allocating and reallocating the command
string pointer for every new key that is added.
This means that MGET performance scales in a linear way rather
than exponentially.
This commit adds methods to get information about the state
of our phpredis object, such as what host/port we are connected
to, our timeout, etc...
The following methods have been added:
getHost()
getPort()
getDBNum()
getTimeout()
getReadTimeout()
isConnected()
getPersistentID()
getAuth()
In addition, there is a small memory leak fix when a persistent id
was specifically passed to connect() (it wasn't beeing freed).
Addresses issue #320
redis_sock_read_multibulk_reply_zipped_with_flag should always return
a value. We merged in a change that handled a certain error condition
that was using RETURN_FALSE (and therefore not returning a value)
Simply changed this to RETVAL_FALSE and return -1;
Added an option to let each RedisArray connection connect lazily to
their respective server. This is useful then working with a redis
cluster composed of many shards which are not necessarily in use all at
once.
New select DB command to RedisArray - Added retry delay on reconnect
Added the possibility to delay each reconnection attempt, including a
random factor to prevent several or many concurrent connections from
trying to reconnect at the same time.
Added the select command to RedisArray to select a DB on every
connections in one instruction.
Also, fixed a compiler warning:
redis_array_impl.c:1115:15: warning: incompatible pointer types
assigning to 'zval **' (aka 'struct _zval_struct **') from 'zval
**(*)[2]' [-Wincompatible-pointer-types]

This commit adds support for the CLIENT commands (list, getname,
setname, kill).
You can call them like so:
$redis->client('list');
$redis->client('getname');
$redis->client('setname', $name);
$redis->client('kill', $ip_port);

continue to destroy and reallocate the command buffer
Added a simply library routine to append to a command buffer
using a smart_str
Made the unit tests work even if you're not compiled with
igbinary
Addresses issue #287
