c1bf2ba7ac New buffer manager implementation (very simple; just stores pages in memory, addressed via an array of pointers) 2007-03-04 02:46:23 +00:00
Sears Russell
e49e8c004e dirtyPages_deinit was broken. (Was excercised by new pageArray bufferManager...) 2007-03-04 02:44:19 +00:00

2d3fc4ba47 Changed malloc() to calloc() to prevent unpacked structs from leaking 
bytes to log

078b45dbcc Removed and/or flagged #include dependencies on pageFile.h (in the process of further factoring bufferManager implementation out of Stasis.) 2007-03-03 02:26:17 +00:00
Sears Russell
73788eb910 Reworked intialization code, includes to isolate bufferManager 
implementation from the rest of Stasis.

b3152261b4 Xid -1 leads to illegal memory accesses. Added checks for it; fixed 
problematic unit test.

fe30fbbd74 RangeTracker seems to be working; still need to write unit tests for its return value. 2007-02-06 02:32:01 +00:00

3b1135ea2f Miscellaneous cleanups, slightly more conservative latching. 2007-01-30 18:26:59 +00:00

05275bbe5a Tracks ranges in O(m log n) time. 2007-01-24 18:25:38 +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.

fcb0a33da9 New directory for testing application code 2006-12-18 00:48:18 +00:00

5b56370980 Fixed append. (It wasn't calling updateEOF, as it should have been. Also, updateEOF assumed start_pos was zero) 2006-11-22 05:04:48 +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
1dbf1145ca Update to detect changes in file size (to support multiple file handles...) 2006-11-21 06:47:35 +00:00

b8d0ccce79 Modularized the build; made berkeleydb and confuse optional. No longer build as many things by default. 2006-11-09 23:00:50 +00:00

9294f89277 Fix for fallback posix_memalign implementation. (Inserted missing 
casts)

Sears Russell
c86688884a Updates for 32-bit x86. There are still real 32-bit bugs being emitted as compiler warnings. 2006-11-07 20:36:59 +00:00

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
bb9e339823 changed to deal with new LinkedList api. 2006-10-28 03:31:27 +00:00
Sears Russell
aa445bdfe5 slightly more general purpose; deals with longs instead of ints. 2006-10-28 03:30:45 +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

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

1575d97a6b Fixed recovery bug. TregionDealloc was being called during redo(), causing an assert to fail. Without the 
assert, would have gone into infinite recursion.

71f51d11bc Fixed a performance bug that was causing logical operations to unnecessarily pin pages. 2006-10-05 22:05:50 +00:00
