Niels Grewe 6f267319e3 Optionally allow the caller to specify the time it wants to block on an 
empty FIFO. This supplements the existing method of having a timeout on
the FIFO, and does not raise an excepion when the wait time is too long.

Raw Blame History

2015-07-17 Niels Grewe <niels.grewe@halbordnung.de>
* GSFIFO.m: Implement methods that allow waiting on an empty
FIFO for an arbitrary period of time, without raising an
exception.
2015-07-16 Niels Grewe <niels.grewe@halbordnung.de>
* GSFIFO.m: Implement -sizeInBytesExcluding:
2015-07-15 Richard Frith-Macdonald <rfm@gnu.org>
* GSCache.m: Experimental change (use in conjunction with gnustep-base
from svn 38799) to put object memory footprint interrogation into the
base library and make it more accurate and efficient.
2015-05-05 Niels Grewe <niels.grewe@halbordnung.de>
* GSFIFO.m: Fix a potential race condition in -peekObject.
2015-05-05 Niels Grewe <niels.grewe@halbordnung.de>
* GSFIFO.[hm]: Add methods to peek at the top/front object in the
FIFO without removing it.
2015-04-28 Niels Grewe <niels.grewe@halbordnung.de>
* GSFIFO.m: Use -autorelease rather than -release when returning
objects from a FIFO. Fixes a bug where a returned reference would
already be invalid because the FIFO was the last owner of the object.
2015-01-09 Richard Frith-Macdonald <rfm@gnu.org>
* GSFIFO.[hm]: add methods for working with objects and handling
retain/release to treat a FIFO as a container.

* GSCache.m
Import inttypes.h for pointer formatting

New code to implement uniqued copies of objects for lowered memory
footprint and faster collection lookups.

get/put.

* GSIOThreadPool.m:
Add default for initialisation of shared pool, fix bug in setting
new thread and add code for shrinking the pool size (previously
setting it smaller did not actually cause old threads to exit).

* GSThreadPool.h, GSCache.m
shutup clang warnings
2013-02-03 Richard Frith-Macdonald <rfm@gnu.org>
* GSTicker.m: Retain timer so that we can safely invalidate it even
on thread exit when the runloop of the current thread may have been
deallocated already.
2012-01-11 Niels Grewe <niels.grewe@halbordnung.de>
* GSSkipMutableArray.m: Change -initWithObjects:count: declaration

* GSFIFO.h:

and removal, we can signal threads waiting at the other end.

ensure that only one thread gets to set the base timestamp.
