c1f485cc31 Simplify mp lambda lists 
Remove redundant keyword-name specification from make-locks recursive
and remove dummy &key from barrier-wait (potentially not backward
compatible with C code).

fe0453fc08 explicitly cast original in queue.d 
original is declared as volatile, but pthread_* discards this
qualifier. Do explicit cast to get rid of warning.

0badafcd35 multiprocessing: add predicate "mp:holding-lock-p" 
This predicate returns T if lock is hold by the process and NIL if it is
hold by another process or is released.

11e35ea5b9 windows: gc: remove spurious define 
Older bdwgc didn't export that symbol, so ECL patched that definition
for its own threaded needs. bdwgc has improved since then and our own
definition breaks CC builds. Fixes #288.

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.

5e43ec8789 Implement a few non-blocking MP functions: 
MP:TRY-GET-SEMAPHORE
   returns NIL if the semaphore could not be obtained, or the count
   if it could be obtained

 MP:MAILBOX-TRY-READ
   returns a message if it's available, NIL if the queue is empty

 MP:MAILBOX-TRY-SEND
   returns the sent message if it could be queued, or NIL
   (mailbox is full)

2f869e6eb6 windows: when using msvc, don't handle interrupts 
Installed spawning process was broken and unimportant. ECL ignores C-c
interrupt and passes forward all the others when build with
msvc. Fixes #8.

42f0b2eaa5 Fixed problems in ecl_register_current_thread(). First, allocation of environment and process structures could not proceed when ecl_process_env() did not return a valid environment. Second, we can only call GC_unregister_my_thread() when the thread was not created by the garbage collector itself, for which we must inspect the output of GC_register_my_thread() 2012-09-27 23:06:56 +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
