preprocessor limitation.
 2018-09-14 20:57:55 +02:00

Patrick Pelissier 8e2031bf5a Add comments. 2018-08-15 10:30:17 +02:00
Patrick Pelissier 8bb5f5475e Avoid putting the push mutex & the pop mutex inside the same cache line. 
Avoid false sharing for multi-threading scenario and should increase performance.
 2018-08-15 10:21:23 +02:00
Patrick Pelissier aba1ac1646 Fix issue in 64 bits with overwriting enabled for buffer. 2018-08-02 23:31:48 +02:00
Patrick Pelissier 96202aa78f Do not use reserved identifiers of the C standard (See 7.1.3 Reserved identifiers) 2018-07-14 14:35:14 +02:00
Patrick Pelissier 70a4fd99f4 iFix buiild issue with mutex based atomics. 2018-06-29 21:43:33 +02:00
Patrick Pelissier 0bf84a321b Add missing methods _capacity for MPMC queue & SPSC queue. 2018-06-27 07:28:34 +02:00
Patrick Pelissier 08f44845ce Fix issue for SPSC queue: 
computing the number of elements in the queue is not reliable enough
as we can get more than than the size of the queue.
 2018-04-26 22:41:11 +02:00
Patrick Pelissier 4fbffc4788 Use plain 'unsigned int' instead of 'unsigned long long' 
for index of SPSC queues. There is no issue as we don't compare
the index, but only substract them.
 2018-04-26 22:38:43 +02:00
Patrick Pelissier 8cf4050d3d Remove uneeded alignment constraint for SPSC queue. 2018-04-26 22:26:30 +02:00
Patrick Pelissier 005207cfd6 Remove a warning in release mode. 2018-04-26 22:05:36 +02:00
Patrick Pelissier f3de34a62b Optimization for MPMC queues: 
* use of atomic_explicit functions to give the memory order we want,
* reduce the size of the index to unsigned int: even if there is an
overflow, it doesn't matter as we don't compare the index with < or >
but with ==.
 2018-04-19 22:15:37 +02:00
Patrick Pelissier ba72e4ebbf Remove check in protected contract: 
since there are two mutex now, there are data race when we want to check it.
TODO: Properly separate the contract.
 2018-03-17 19:54:59 +01:00
Patrick Pelissier d82dc196e0 Fix datarace (?) if support for pop deferred has been activated 
(a rewake of thread may be lost)
 2018-03-16 23:55:16 +01:00
Patrick Pelissier f2b2335080 Fix issue with C++ not supporting passing an int constant value to an unsigned atomic type... 
I definitely find this disturbing.
 2018-03-16 22:59:51 +01:00
Patrick Pelissier cbb881df86 Fix overwrite branch which has a data race on number. 
Rewrite it to be simpler & faster and without data race.
 2018-03-10 10:13:54 +01:00
Patrick Pelissier 103e5304e8 Use of 2 mutex for buffer: 
* one for the enqueue
* one for the dequeue
The number of items in the buffer is the only variable which can be accessed
by both at the same time.
This improve the performance of the communication and reduce the possibility
of priority inversion between the producer and the consummer thread.
 2018-03-09 21:07:21 +01:00
Patrick Pelissier 65f39ab22e Optmize the buffer queue: 
don't broadcast the condition variable if we know that
 no thread is waiting for it.
 Improve bench test from 700ms to 450ms
 2018-03-09 19:15:47 +01:00
Patrick Pelissier c71613dcfe Don't display warnings about unused variables in release mode. 2018-02-28 21:05:15 +01:00
Patrick Pelissier b1443533e0 Update comment 2018-02-27 22:41:11 +01:00
Patrick Pelissier 2da51ea6e9 Remove constraint on size > 0 
as workers can create a queue of size 0
in mono core system.
 2018-02-23 22:12:17 +01:00
Patrick Pelissier d0e7cc41bf Add more assertions 2018-02-23 20:40:44 +01:00

Patrick Pelissier 55332d61fd Fix data race for buffer in POP_RELEASE mode. 2018-01-12 18:52:34 +01:00
Patrick Pelissier 4f3823bfeb Add new function _blocking allowing to use 
runtime behavior of the blocking characteristic of the
buffer regardless on how it has been configured.
 2018-01-07 00:07:27 +01:00
Patrick Pelissier 3f7b16c736 If the size is constant (!= 0) when defining the buffer 
then the array is embedded within the structure rather
than allocated when initialization of the structure
occurs.
