d1aeba8a82 Cleaned up obsolete @todo's; fixed inconsistent page file initialization 2007-06-01 21:06:18 +00:00

bff22716a7 Updated page.h's interface to make it more consistent. 2007-05-31 01:15:12 +00:00

362b1036de Changed CLR log format so that it is identical to update entries. The old format pointed back to an earlier 
entry in the log, complicating truncation significantly.  The new format copies log entries into their CLRs,
and is somewhat redundant, as redo and undo information is stored in the CLR, but the undo information will
never be used...

8275eb71be Cleanup and refactoring for deferred updates. CLR's were broken; Tdefer requires them, so it is 
only partially implemented.

44aef7e8ea Added ability to override default logging implementation with 
-DUSE_LOGGER

3b1135ea2f Miscellaneous cleanups, slightly more conservative latching. 2007-01-30 18:26:59 +00:00

836d2d097d Fixed initialization bugs on pendingCommits and syncLogCount. Group commit used to hang with 100% CPU if a signal interrputed it. Now it ignores the signal. (Don't know why it's receiving a singal, so it warns when this happens...) 2006-10-05 00:50:21 +00:00

4bd93ee66a Added support for computing size of internal log entries. 2006-10-04 04:38:21 +00:00

f01cff0d5b Cleaned up logger API, added truncation support to inMemoryLog.c 2006-09-27 20:30:12 +00:00

c8c9b7af19 the logger understands special record types. (At least partially...); shortened blob tests, since the blob 
implementation is fundamentally broken, and slow

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.

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

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

96e7af92a4 Added test cases for Tprepare(), implemented some redo-only operations, and started to clean up record allocation/deallocation. 
Also, numerous bugfixes.

82e3fdb53a Added (untested) support for whole-page operations, lladdhash now works. 2004-08-03 02:04:56 +00:00

961b63af15 Rewrote / refactored page.h. Now, it uses a freelist to reclaim slotid's within a page, and is implemented as two seperate modules. The first handles lsn's, and (will soon) check the type of each page, and then delegate work to a particular implementation of the second module. 2004-07-30 01:28:39 +00:00

422198418a bufferMananger is (really!) re-entrant now, performed big refactoring to prevent deadlocks, check_transactional2 ran overnight without coring, w/ 25 threads, and 10000 allocate/write/reads per thread. (The whole test suite was run in a loop...) 2004-07-23 20:21:44 +00:00

9712e291e6 Moved page.h and some of the logging headers out of the public API. 2004-07-14 21:25:59 +00:00

c4fac084b8 Cleaned out old cruft, such as commented out code, dead data structures, and dead files. sloccount went from $75,000 to $50,000 on src/lladd. ;) 2004-06-28 22:48:02 +00:00
