Bugfix.

Lots of optimizations; re-did on-disk layout for the linear hash table.

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

The logger now calls fwrite half as often as it used to. This could be improved significantly, but some latching details internal to the logger need to be worked out first.
2004-10-18 19:19:10 +00:00

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

Optimized the 'naive' linear hash table, and moved to sourceforge. :)
2004-10-17 02:17:00 +00:00

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

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

Added support for gcov, and ran gprof. Shaved 10% off the runtime of check_page by optimizing rw.c
2004-10-04 05:24:12 +00:00

96e7af92a4
Added test cases for Tprepare(), implemented some redo-only operations, and started to clean up record allocation/deallocation.
...
Also, numerous bugfixes.
2004-10-02 07:29:34 +00:00

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

Fixed regressions, major update of page / slotted interfaces in anticipation of moving LLADD towards a generic transactional page system.
2004-08-17 01:46:17 +00:00

Added (untested) support for whole-page operations, lladdhash now works.

Test cases for indirect blocks.
2004-07-31 00:28:45 +00:00

Implemented indirect pages, and fixed some bugs here and there. (Still need to add transactional support for indirect pages...)

Fixed data corruption bug in the freelist implementation, and corrected lsn updates.
2004-07-30 02:07:41 +00:00
Sears Russell
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.

O_DIRECT (sort of...)
2004-07-27 21:30:54 +00:00

Refactored bufferMananger / pageCache, so that bufferMananger handles loading an unloading pages, and pageCache only implements the replacement policy.
...
Also, used memprof to detect and remove all memory leaks (at least all memory leaks that are encountered by check_transactional2), and fixed a number of misuses of the pblHash.
