Added support for raw pages, implemented posix_memalign workaround, and re-enabled O_DIRECT by default

corrected slottedFrespace()'s declaration (it was returning an int, but needed to return a size_t

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.

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

More freespace troubles... Should be correct now.

The freespace calculations were double counting the new slot's header.

Enabled compactPage in TallocFromPage()

Fixed unit tests, added iterator interface, and generic (almost) iterator test harness.

Fixeds cht test / finished error checking within LLADD, but haven't tested error handling yet.

More error handling...

Numerous lock manager fixes; more realistic test case for lock manager, added support for optional page-level locking.(Still need to report deadlocks back up to the caller.)

page->dirty is now set correctly (assuming LSN's are updated properly). pageFile.c makes use of this fact by ignoring write requests on clean pages.
2005-02-02 02:12:40 +00:00

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.

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
Sears Russell
17f76264aa
Implemented pageOrientedList, also did some bug fixing, and added some support functions to alloc.c

Fixed nasty bug that was causing the LLADD header to be lost (!!)

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

Speedups, most notably in the logging subsystem.

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

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
Sears Russell
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.
2004-08-03 02:04:56 +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.
