f77e8b240d It was improperly tracking the log's global offset. (Hopefully) 
fixed offset tracking, made it optional, and disabled it.

e0b34633ec Fixed broken min_rec_lsn() semantics; before, if there were not outstanding transactions / writes, 
then these calls would return flushedLSN().  The problem was that flushedLSN wasn't guaranteed to
return a pointed to the beginning of a log entry.

7decae7172 All tests that pass with LOG_TO_FILE now pass with LOG_TO_MEMORY, but LOG_TO_MEMORY is slow, and seems to be 
killing malloc's performance for some reason.  (linearHashNTA spends many seconds in free() between unit
tests...)
 2006-04-08 00:05:09 +00:00

d3d7f2c788 Implemented "LOG_TO_MEMORY", which mostly works (linear hash NTA goes into an infinite loop....) 2006-04-07 03:40:40 +00:00

1c979f3052 Factored logWriter.h out of the rest of the system. The only file that directly depends on it is logger2.c, which can 
now dispatch requests to different (hardcoded) log implementations.

d9f1df0476 Fixed behavior when __really_do_ralloc() is called, but the record's slot is greater than numslots_ptr(). 
Optimized slotted_compact and __really_do_ralloc() so that they try to put lower numbered slots earlier in the freelist.

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

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.

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

Sears Russell
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

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
