8f07cd58d8 The ECL code no longer uses tabulator characters, they were replaced 
by spaces.

A custom script was used to insert/replace Emacs and ViM per-file editor
settings according to their type and the new ECL coding style.

7a4a98d020 The owner of a lock now passes ownership to the first waiting process. 2012-07-30 22:49:56 +02:00

14d2960135 Use a spinlock for a thread wait until its process structure is completed by its parent. Rename waiting_for to woken_up for the real application it has. 2012-07-30 22:11:50 +02:00

0bc0dcf523 Remove statements that attempted at prioritizing the waiting queue and a bogus optimization that layed outside the appropriate locks 2012-07-29 22:03:32 +02:00
Juan Jose Garcia Ripoll
7638ca49ab Sacrifice fairness from the wait queue because otherwise we miss events. 2012-07-28 00:11:15 +02:00

23d5394a2e When a condition variable is signaled, it does not suffice to wakeup the process: we have to remove it. This is so because two consecutive calls to condition-variable-signal must delete two different processes. 2012-07-13 23:46:14 +02:00
Juan Jose Garcia Ripoll
595f3dbe58 The previous implementation of condition variables was wrong: it assumed that the signaling thread did not own the lock. 2012-07-11 00:06:33 +02:00

323822457c In the queue, when the first process of the queue leaves it, it awakes the next one in line to test its condition. 2012-04-15 22:48:33 +02:00

94c86a0af1 Simplified ecl_wait_on(): optimized detection of being first one and abortion, waking up is done with the lock held, woken up threads are not removed from queue. 2012-04-14 11:43:39 +02:00

3980ea5d66 Removed the process.active field and instead used 'process.phase'. Added some debug statements. Threads are launched also with POSIX signals disabled (at least ECL's signal). 2012-04-06 18:07:58 +02:00

e278e1d5a7 When the lock is interrupted, we have to ensure that some thread is woken up. 2012-03-31 11:17:27 +02:00

008a260e1f In ecl_wait_on(), take care of the situation in which we abort waiting but do not care to acquire the lock: the other waiters must then be awoken. 2012-03-31 10:54:01 +02:00

d54cbaa749 ecl_check_pending_interrupts() now takes the environment as argument 
To wake up a process we need not supply any function (it is faster as it saves a call to queue_signal()
