8275eb71be Cleanup and refactoring for deferred updates. CLR's were broken; Tdefer requires them, so it is 
only partially implemented.
 2007-03-30 09:16:21 +00:00

4c8466555c Cleaned up Tupdate() by adding TupdateRaw(); removed *_RAW and updated linear hash accordingly. 2007-03-28 09:21:07 +00:00

61249c29a7 New "default" buffer manager that aims to replace the current one, but 
without deadlocks.  Still need to track down a memory corruption bug
that this introduces, or exercises.

8f3d503ea8 Added TdurabilityLevel(). 
Test cases now pass with LOG_TO_MEMORY and BUFFER_MANAGER_MEM_ARRAY

73788eb910 Reworked intialization code, includes to isolate bufferManager 
implementation from the rest of Stasis.

c413203ec8 Talloc() now reuses space when possible. It still needs to call slottedCompact() intelligentally. Also, allocationPolicy should support an extra tier 
of pages, so it doesn't suggest ones that aren't already in the buffer pool unless it has to.
 2006-07-29 00:56:54 +00:00

e9880654e4 Added the INVALID_XID constant. 2006-07-27 00:03:36 +00:00

6501e7a24d MAX_BUFFER_SIZE can now be specified in CFLAGS. 2006-07-25 17:43:39 +00:00

0f45b97eda regions now make use of nested top actions, so they're almost correct. (Still need to lock freed regions until end of transaction.) 2006-07-25 00:56:50 +00:00

0725af91be Fixed page leak in Talloc(). 2006-07-21 01:07:09 +00:00

ffd3bd960b switched to region allocator, but TpageAlloc currently grabs its own region... 2006-07-20 01:29:39 +00:00

1ac3dc6779 More progress on boundary tags. (Still not tested/working yet...) 2006-07-18 23:59:00 +00:00

3e4cac0fe3 Continued cleaning up allocation code. It seems really slow all of a sudden, so this commit probably introduced a performance bug. 2006-06-17 00:25:09 +00:00

50515ffd23 More steps toward factoring page allocation out of record allocation. 2006-06-15 05:31:20 +00:00

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

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
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.

72070acb67 Implemented TsetRange, fixed bug in linear hash. 2004-12-03 00:27:47 +00:00

6b265f28b0 Speedups, most notably in the logging subsystem. 2004-10-19 04:45:42 +00:00

ec1276f26f Preliminary version of logical logging linear hash. (No latching yet, and there are some bugs re-opening a closed hash.) 2004-10-18 18:24:54 +00:00
Sears Russell
a078f25475 Implemented a linear hash from scratch. Concurrency hasn't been done, but it's probably correct in the single thread case. 2004-10-12 02:44:47 +00:00
Sears Russell
5064e3fac2 Implemented pages that store fixed sized records efficiently, and a java-style ArrayList data structure that efficiently supports (relatively) clustered, O(1) access time expandable arrays. (This will be used for the hash implementation...) 2004-10-06 06:08:09 +00:00
Sears Russell
96e7af92a4 Added test cases for Tprepare(), implemented some redo-only operations, and started to clean up record allocation/deallocation. 
Also, numerous bugfixes.

811bc5c710 Implemented a freespace manager that should safely allocate space, even in the face of crashes, and can reclaim unused space (unless an application opens more than one simultaneous transaction that performs allocations) 
Fixed some blob bugs (by adding extra fdatasync() calls).

Began factoring out the page management code so that it is an extenstion, and a less integral part of lladd.
 2004-08-21 00:03:30 +00:00
Sears Russell
82e3fdb53a Added (untested) support for whole-page operations, lladdhash now works. 2004-08-03 02:04:56 +00:00

3349dbc6dc Log truncation. (But no checkpoints, so it doesn't get called... it does pass testing though. :) 2004-07-01 00:53:36 +00:00
