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...

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

Fixed a performance bug that was causing logical operations to unnecessarily pin pages.

Fixed segmentation fault when a CLR with a NULLRID is encountered. I
...
don't understand why this bug wasn't triggered by linearHashNTA or
linkedListNTA, but is triggered by the new region implementation.

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.

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.)

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

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

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...)

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.
