cf58e1fb72 Transitive closure working! 2005-03-24 04:43:22 +00:00

2f99ed4664 Generic consumer wrapper functions, and implementation registrations. 2005-03-23 08:10:30 +00:00

ee9eb416ea Implemented fifo pool that allocates entries out of a pool (it should be easy to extend this to avoid deadlock, while allowing it to continue to provide backpressure) 2005-03-23 08:07:53 +00:00

d8eb6c9aa7 Major benchmark update; log force merging. 2005-03-17 04:38:55 +00:00

bf4be359b3 Partially refactored logMemory and multiplexer into a fifo implementation. Added support to fifoPool for 
asynchronous threads running round-robin through the dirty fifos consuming entries in idle ones.

dffff067bb multiplexer and fifo are now working. (also added removed some timeouts from tests that were timing out) 2005-03-15 05:30:57 +00:00

80ed16c18e Initial implementation of logMemory.c. Haven't yet done any testing, but it seems to compile. However, as of now, the current source code in the cvs repository does not build, dying on check_<somehting (I think ringbuffer.x)>, due to an a reference to an undefined symbol 'mutex'. 2005-03-14 20:54:06 +00:00

1bfb634103 Preliminary benchmark program uploads for SEDA-style response time percentiles vs requests / second 
Also added a few cute little utilities:
  - truncate_log
  - run_recovery

Upped max # of concurrent transactions.  (Current throughput during benchmarking remains ~flat up to 32,000
threads, but past max concurrent transactions was 1,000...)

18c772234d new benchmarks revealed that inserts for linkedList, pageOrientedList were taking O(n) time, yielding O(n^2) 
time to build a list, since the lists could not contain duplicate keys.  These operations are now O(1), and
the lists can contain duplicates.

f4484e35b5 Update for perl script; added return type handling. 2005-02-16 02:13:54 +00:00
Sears Russell
fdf5344ec3 Implemented 'compensations' for C. They're not proper compensations, but they're more flexible than pthread's mechanisms, as they allow the stack to be partially rolled up. (Although calling functions need to either check for errors and return manually, or wrap calls to error-producing callees in a begin_action{ }end_action block. 2005-02-14 02:49:59 +00:00

b8a67cbfb2 Numerous lock manager fixes; more realistic test case for lock manager, added support for optional page-level locking.(Still need to report deadlocks back up to the caller.) 2005-02-10 03:51:09 +00:00
Sears Russell
6f022cc577 Some random code cleanups, and implemented a naive lock manager. (Still need to tie it into LLADD...) 2005-02-09 02:53:14 +00:00

258dd5f4c4 Fixed up some return values; tests now pass with assert disabled. 2005-02-08 01:13:57 +00:00

54ecc0d3c4 page->dirty is now set correctly (assuming LSN's are updated properly). pageFile.c makes use of this fact by ignoring write requests on clean pages. 2005-02-02 02:12:40 +00:00

1260710a27 Got rid of another broken hash implementation... 2005-01-31 01:34:29 +00:00
Sears Russell
bb69197a65 Fixed blob implementation (it was impossible to distinguish between a blob and a record of length 12), removed jbhash, and ported cht to linearHashNTA. 2005-01-31 01:29:52 +00:00
Sears Russell
7cf5fdee6e Re-implemented pageOrientedListNTA from scratch. It's now more flexible, but relies on features that are not provided by Talloc/Tdealloc, so performance isn't as good as it could be. 2005-01-29 01:17:37 +00:00

4d04155b0e An optimized, but still slow implementation of pageOrientedList. 2005-01-29 01:09:29 +00:00

56d98adcbf Working, but slow and non-concurrent variable length key/value support for linear hashtable. 2005-01-28 21:28:23 +00:00
Sears Russell
17f76264aa Implemented pageOrientedList, also did some bug fixing, and added some support functions to alloc.c 2005-01-28 03:32:17 +00:00

05934d296a Removed O_DIRECT since it breaks on 2.4 kernels. Need to figure out how to 
detect this in the build script so that systems that support O_DIRECT can use it.

(Note:  RedHat kernels silently fail on O_DIRECT)

894e30085c libdfa ported to new hash table implementation. (Uses nested top actions.) 2005-01-15 23:55:49 +00:00
Sears Russell
ac0d413e58 - linkedListNTA is now re-entrant. 
- linearHashNTA now uses nested top actions, is re-entrant, and supports a
  non-re-entrant iterator
- 'recursive' nested top actions allow nested top actions to be nested within each
  other.
 2005-01-15 01:45:27 +00:00
Sears Russell
7a990886d2 The linked list implementation now uses nested top actions. (Also, many bugfixes regarding nested top actions were introduced.) 2005-01-14 10:08:10 +00:00
