bf4be359b3 Partially refactored logMemory and multiplexer into a fifo implementation. Added support to fifoPool for 
asynchronous threads running round-robin through the dirty fifos consuming entries in idle ones.

80ed16c18e Initial implementation of logMemory.c. Haven't yet done any testing, but it seems to compile. However, as of now, the current source code in the cvs repository does not build, dying on check_<somehting (I think ringbuffer.x)>, due to an a reference to an undefined symbol 'mutex'. 2005-03-14 20:54:06 +00:00

1bfb634103 Preliminary benchmark program uploads for SEDA-style response time percentiles vs requests / second 
Also added a few cute little utilities:
  - truncate_log
  - run_recovery

Upped max # of concurrent transactions.  (Current throughput during benchmarking remains ~flat up to 32,000
threads, but past max concurrent transactions was 1,000...)

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.

f4484e35b5 Update for perl script; added return type handling. 2005-02-16 02:13:54 +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
Sears Russell
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.
 2005-02-08 22:06:24 +00:00

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).

258dd5f4c4 Fixed up some return values; tests now pass with assert disabled. 2005-02-08 01:13:57 +00:00

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
