18c772234d new benchmarks revealed that inserts for linkedList, pageOrientedList were taking O(n) time, yielding O(n^2) 
time to build a list, since the lists could not contain duplicate keys.  These operations are now O(1), and
the lists can contain duplicates.

6360eae602 autoconf macro for finding lladd. (only supports source tree versions of lladd for now, since lladd is 
uninstallable)

f68e6b9dd3 Heuristic perl script to check for proper use of compensations. 2005-02-16 02:11:01 +00:00
Sears Russell
fdf5344ec3 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. 2005-02-14 02:49:59 +00:00

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

6f022cc577 Some random code cleanups, and implemented a naive lock manager. (Still need to tie it into LLADD...) 2005-02-09 02:53:14 +00:00

815942ed4c - some further API improvements (?). 2005-02-08 23:56:47 +00:00

307f268fdc - working with flags instead of Boolean arguments; replaced some specialized 
function calls with header-file macros.

b2b0e8a9d4 - test_list2.c now issues a secondary init/shutdown sequence, just to make 
sure that repeated init/shutdown works correctly.
 2005-02-08 08:05:24 +00:00
Gilad Arnold
b0a9265d1a - enhanced init/shutdown semantics: init may now be re-issued, following a 
predecessing shutdown; note that shutdown does not deallocate objects (either
  persistent or non-persistent), hence re-init would use the same objects as in
  the previous run (assuming they are all intact).

eec80a0e38 - improvement to error handling in pobj: now properly handles resource 
allocation errors (at least most cases...?), including hash/queue
  library calls.

c94bee33a3 - cosmetic changes to debug logging. 2005-02-07 07:59:40 +00:00

037c164728 - cosmetic fixes in hash module 
- new debug facility to show context-based (stack) debugging messages; turned on
  by corresponding compile switch (HAVE_DEBUG_CONTEXTS, currently hard-coded in
  debug.h)

- added use of dedicated queue module (supporting dynamic allocation and
  growable buffers).

- improvement w.r.t. full error handling in pobj.c: tackled some error cases
  with library calls (malloc, hash module calls, etc) -- but still there's a way
  to go.

f96061a1bd - implementation of growable queues; to replace fix-sized queues used 
in recursive traversal functions.

91f2c7c382 - moved pobj header internals back into the .c file (sorry Amir) 
- added pobj_is_persistent() call to replace the formerly used macro

- minor rearragement of common contants/macros

- minor fix to makefile

1fd827a59e - cosmetic: changes all shorthand for 'repository' from 'rep' to 'repo'... 
- handling error return value of hash_insert in two cases (still two other left)

c3229723ab - removed std99 and pedantic flags for GCC (caused annoying warnings 
with variable argumented macros).

54ecc0d3c4 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. 2005-01-31 01:29:52 +00:00
Sears Russell
7cf5fdee6e 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

4d04155b0e An optimized, but still slow implementation of pageOrientedList. 2005-01-29 01:09:29 +00:00

56d98adcbf Working, but slow and non-concurrent variable length key/value support for linear hashtable. 2005-01-28 21:28:23 +00:00

17f76264aa Implemented pageOrientedList, also did some bug fixing, and added some support functions to alloc.c 2005-01-28 03:32:17 +00:00

05934d296a Removed O_DIRECT since it breaks on 2.4 kernels. Need to figure out how to 
detect this in the build script so that systems that support O_DIRECT can use it.

(Note:  RedHat kernels silently fail on O_DIRECT)
