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.

Added -fno-strict-aliasing to the CFLAGS for the unit tests... This is
...
easier than making all this code -O2 clean... (The rest of lladd now
compiles without warning under -O2, so this seems like a good
tradeoff...)

Added the base functionality and test case for the BTree... just a hello world method. but it has the h, c and check files. -colleen ;)

Portability fixes for FreeBSD and Mac OS. Check broke compatibility w/

old versions; added #ifdef so that both versions of check will work.

Implemented 'compensations' for C. They're not proper compensations, but they're more flexible than pthread's mechanisms, as they allow the stack to be partially rolled up. (Although calling functions need to either check for errors and return manually, or wrap calls to error-producing callees in a begin_action{ }end_action block.

Some random code cleanups, and implemented a naive lock manager. (Still need to tie it into LLADD...)

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

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

The linked list implementation now uses nested top actions. (Also, many bugfixes regarding nested top actions were introduced.)

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.

Preliminary version of logical logging linear hash. (No latching yet, and there are some bugs re-opening a closed hash.)

Implemented a linear hash from scratch. Concurrency hasn't been done, but it's probably correct in the single thread case.

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.

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.

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.)
