Raw Normal View History

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...)

* alloc.h, instantSet.h, noop.h, prepare.h:
Added test cases for Tprepare(), implemented some redo-only operations, and started to clean up record allocation/deallocation.
Also, numerous bugfixes.
2004-08-21 sears@euglenoid <sears@euglenoid>
* pageOperations.h:
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.
2004-08-03 sears@euglenoid <sears@euglenoid>
* lladdhash.h, pageOperations.h:
Added (untested) support for whole-page operations, lladdhash now works.

bufferMananger is *really* reentrant now! (I think) However, the same thread may not load a page more than once. So, LLADD has to be altered so that it never calls loadPage() more than once per operation (more efficient), and/or pin/unpin need to be implemented. An easy way to do pin/unpin is to have them pull things out of the cache replacement list, and then re-insert them.

* bufferManager.c, common.c, operations/alloc.c, page.c, page.h, pageCache.c, pageFile.c, transactional2.c:
Continuing work on multi-threading. r/w access to buffer manager getting close, but still buggy.
* logger/logWriter.c, pageFile.c, pageFile.h, bufferManager.c, common.c, latches.h, page.c, page.h, pageCache.c:
pageCache.c is now re-entrant.
2004-07-15 sears <sears@Morphix>
* Makefile.am, blobManager.c, bufferManager.c, logger/logWriter.c, page.h, pageCache.c, pageFile.c, pageFile.h:
pageCache is now re-entrant, in theory.
2004-07-14 sears <sears@Morphix>
* blobManager.c, blobManager.h, bufferManager.c, logger/logHandle.c, logger/logHandle.h, logger/logWriter.c, logger/logWriter.h, logger/logger2.c, operations.c, operations/alloc.c, operations/prepare.c, page.c, page.h, pageCache.c, recovery2.c, transactional2.c:
Moved page.h and some of the logging headers out of the public API.
* blobManager.c, bufferManager.c, latches.h, logger/logEntry.c, logger/logWriter.c, logger/logger2.c, operations.c, operations/alloc.c, page.c, pageCache.c, recovery2.c, transactional2.c:
Cleaning up bufferManager / page for locking. Want to limit access to the Page struct.
2004-07-13 sears <sears@Morphix>
* page.c, pageCache.c:
page.c is re-entrant (mostly), and now reuses DeRalloced space properly. (For now, BufferManager still is not re-entrant, and also prevents space from being reused.)
2004-07-09 sears <sears@Morphix>
* bufferManager.c, page.c: Made pageWriteLSN static.
2004-07-06 sears <sears@Morphix>
* bufferManager.c, page.c: More documentation fixes.
* blobManager.h: Fixed groupings for LLADD API docs.
* operations/alloc.c, operations/lladdhash.c, logger/logWriter.c, logger/logger2.c, logger/logEntry.c, operations.c, page.c, pageCache.c, recovery2.c, stats.c, transactional2.c, Makefile.am, blobManager.c, blobManager.h, bufferManager.c, common.c, latches.h, linkedlist.c:
Ported LLADD to Fedora, cleaned up autoconf setup, and numerouse #includes that were problematic.
2004-07-04 sears <sears@Morphix>
* Makefile.am, blobManager.c, blobManager.h, bufferManager.c, common.c, logger/logHandle.c, logger/logWriter.c, logger/logger2.c, operations.c, operations/alloc.c, page.c, pageCache.c, recovery2.c, stats.c, transactional2.c:
Documentation update, added latch profiling tools.
2004-07-01 sears <sears@Morphix>
* logger/logHandle.c, logger/logWriter.c, operations.c:
Log truncation. (But no checkpoints, so it doesn't get called... it does pass testing though. :)
2004-06-30 sears <sears@Morphix>
* Makefile.am, blobManager.c, blobManager.h, bufferManager.c, logger/logWriter.c, operations/alloc.c, operations/prepare.c, page.c, pageCache.c, transactional2.c:
Logwriter can now handler partial log entries correctly (it ignores them)
Buffer Mananger no longer steals pages pre-maturely
Alloc is an operation, and correct.
Caching broken out into a new module
Wrote a utility to translate a log file into human-readable ascii.

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. ;)
* blobManager.c, blobManager.h, bufferManager.c, logger/logger2.c, operations.c, operations/alloc.c, operations/decrement.c, operations/increment.c, operations/set.c, page.c, recovery2.c, transactional2.c:
Bugfixes ; blobs pass regression. Next stop: Delete old cruft.
2004-06-26 sears <sears@Morphix>
* blobManager.c: Wrote blobmanager, didn't compile it yet.
2004-06-25 sears <sears@Morphix>
* blobManager.c, blobManager.h: blob manager commit.
* Makefile.am, bufferManager.c, page.c:
Preliminary implementation of blobManager
