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

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.

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

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

894e30085c libdfa ported to new hash table implementation. (Uses nested top actions.) 2005-01-15 23:55:49 +00:00

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.

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

360f0d15e2 Working, non-concurrent linear hash and linked list implementations. 
The idea is to implement the non-concurrent versions, and then convert
them to concurrent versions using nested top actions.

6198522971 Starting to rip the old jbhash implementation out, and replace it with a 
linear hash implementation.  In particular, I've implemented (sort of) an
iterator for linear hash, and (sort of) ported libdfa to linearhash.c

I say 'sort of' since this functionality is broken with this commit.  On the other hand, CVS should build now, and the tests under lladd will pass.  libdfa's new tests don't pass at the moment.
