34bfccb439 Portability fixes for FreeBSD and Mac OS. Check broke compatibility w/
old versions; added #ifdef so that both versions of check will work.

b8a67cbfb2 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.) 2005-02-10 03:51:09 +00:00

ac0d413e58 - linkedListNTA is now re-entrant.
- linearHashNTA now uses nested top actions, is re-entrant, and supports a
  non-re-entrant iterator
- 'recursive' nested top actions allow nested top actions to be nested within each
  other.

7a990886d2 The linked list implementation now uses nested top actions. (Also, many bugfixes regarding nested top actions were introduced.) 2005-01-14 10:08:10 +00:00

6198522971 Starting to rip the old jbhash implementation out, and replace it with a
linear hash implementation.  In particular, I've implemented (sort of) an
iterator for linear hash, and (sort of) ported libdfa to linearhash.c

I say 'sort of' since this functionality is broken with this commit.  On the other hand, CVS should build now, and the tests under lladd will pass.  libdfa's new tests don't pass at the moment.

55b0ddf1b6 Fixed nasty bug that was causing the LLADD header to be lost (!!) 2004-12-06 01:20:48 +00:00

ded5c92c9d Support for nested top actions, with simple unit test. (Haven't tested for thread safety yet.) 2004-11-29 21:28:13 +00:00

5064e3fac2 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.

422198418a 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...) 2004-07-23 20:21:44 +00:00

126ae31392 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. 2004-07-21 02:13:28 +00:00
