We're starting to see a mix between uses of zend_bool and bool. Replace all usages with the standard bool type everywhere. Of course, zend_bool is retained as an alias.

/*
|
|
zend_accel_hash - is a hash table allocated in shared memory and
|
|
distributed across simultaneously running processes. The hash tables have
|
|
fixed sizen selected during construction by zend_accel_hash_init(). All the
|
|
hash entries are preallocated in the 'hash_entries' array. 'num_entries' is
|
|
initialized by zero and grows when new data is added.
|
|
zend_accel_hash_update() just takes the next entry from 'hash_entries'
|
|
array and puts it into appropriate place of 'hash_table'.
|
|
Hash collisions are resolved by separate chaining with linked lists,
|
|
however, entries are still taken from the same 'hash_entries' array.
|
|
'key' and 'data' passed to zend_accel_hash_update() must be already
|
|
allocated in shared memory. Few keys may be resolved to the same data.
|
|
using 'indirect' entries, that point to other entries ('data' is actually
|
|
a pointer to another zend_accel_hash_entry).
|
|
zend_accel_hash_update() requires exclusive lock, however,
|
|
zend_accel_hash_find() does not.
