11c311bc91 Added support for raw pages, implemented posix_memalign workaround, and re-enabled O_DIRECT by default 2006-04-12 01:41:35 +00:00

c1d8906d28 removed memcpy() calls from inMemoryLog; added "const" qualifier to many LogEntry pointers. 2006-04-11 02:20:21 +00:00

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...)

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.

10e7434d32 corrected slottedFrespace()'s declaration (it was returning an int, but needed to return a size_t 2006-04-05 02:54:14 +00:00

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.

d896155b82 Fixed freespace measurement during recovery/abort by adding slottedFreespaceForSlot() 
(This version is still broken, because __really_do_ralloc() does not properly increment numslots_ptr

041bfce736 The bucket list entries for variable lenth hash tables were too long, causing memory corruption, and wasting space+log bandwidth 2006-04-04 22:34:35 +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

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.
