Sears Russell	fe30fbbd74	RangeTracker seems to be working; still need to write unit tests for its return value.	2007-02-06 02:32:01 +00:00
Sears Russell	99bcf8acd9	Randomized test; bugfixes	2007-01-25 22:38:22 +00:00
Sears Russell	c2fa9913b1	Added partial implementation of range tracking for pinning arbitrary ... regions. Currently, tracks regions, and is O(m log(n)) for each operation, where m is the number of transition points per range, and n is the number of transition points in the system. A transition point is a place in memory where the pincount changes.	2007-01-24 01:03:52 +00:00
Sears Russell	802eeb33e7	New non-blocking implementation, with backpressure. Still doesn't handle overlapping writes. (Multiple writes to the same region is OK though.)	2006-11-21 06:50:12 +00:00
Sears Russell	8481e9cdd6	non_blocking is closer to working (it now flushes writes out in the background). This required some api changes. It still passes unit tests, but it's losing data on close()...	2006-10-28 03:33:02 +00:00
Sears Russell	faf55911df	Added non-blocking io implementation. It doesn't actually work yet, but it passes the unit tests. ;)	2006-10-26 05:48:30 +00:00
Sears Russell	10b77729f5	Simple (blocking, poor truncation performance) file handle implementation.	2006-10-18 00:57:36 +00:00
Sears Russell	32347b12e4	Added a "debug" handle dumps a trace of requests passed to it, and passes the requests through to another handle implementation.	2006-10-17 03:26:01 +00:00
Sears Russell	80a4148543	First cut at a new io API, with an in-memory reference implementation + test case.	2006-10-13 04:39:03 +00:00
