05ad97b37b Was releasing log_read_mutex without obtaining it first... 2007-04-20 07:13:18 +00:00
Sears Russell
362b1036de 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...

Sears Russell
61249c29a7 New "default" buffer manager that aims to replace the current one, but

Sears Russell
73788eb910 Reworked intialization code, includes to isolate bufferManager 
implementation from the rest of Stasis.

05275bbe5a Tracks ranges in O(m log n) time. 2007-01-24 18:25:38 +00:00
Sears Russell
c2fa9913b1 Added partial implementation of range tracking for pinning arbitrary 
regions.  Currently, tracks regions, and is O(m log(n)) for each
operation, where m is the number of transition points per range, and n
is the number of transition points in the system.  A transition point is
a place in memory where the pincount changes.

5b56370980 Fixed append. (It wasn't calling updateEOF, as it should have been. Also, updateEOF assumed start_pos was zero) 2006-11-22 05:04:48 +00:00
Sears Russell
802eeb33e7 New non-blocking implementation, with backpressure. Still doesn't handle overlapping writes. (Multiple writes to the same region is OK though.) 2006-11-21 06:50:12 +00:00

Sears Russell
8481e9cdd6 non_blocking is closer to working (it now flushes writes out in the background). This required some api changes. It still passes unit tests, but it's losing data on close()... 2006-10-28 03:33:02 +00:00

1575d97a6b Fixed recovery bug. TregionDealloc was being called during redo(), causing an assert to fail. Without the

836d2d097d Fixed initialization bugs on pendingCommits and syncLogCount. Group commit used to hang with 100% CPU if a signal interrputed it. Now it ignores the signal. (Don't know why it's receiving a singal, so it warns when this happens...) 2006-10-05 00:50:21 +00:00

appropriate.
 2006-08-10 23:57:49 +00:00

af175896cb Added logWriter_isDurable. If = 0, then the log will never be forced. 2006-08-10 23:54:46 +00:00
Sears Russell
1b6c828bd2 Added logWriter_isDurable. If set to zero, the log will never be forced 
to disk.

3a43450477 Force in-flight page file writes to disk before truncating. (Needed if 
O_DIRECT isn't in use.)

Changed diagnostic messages to go to stderr.
 2006-08-10 23:52:48 +00:00
Sears Russell
f93b2acf69 Now, you can set pageFile_isDurable=0 to disable forcing data to the 
page file.

Also, -DPAGE_FILE_O_DIRECT switches the page file from using a normal
file handle and fdatasync to use O_DIRECT with no fdatasync.

 2006-08-10 23:45:25 +00:00

6fcaf34bb5 Needed to protect a linked list with a mutex. It's suprising that this hasn't come up before. 2006-08-08 01:41:45 +00:00
Sears Russell
8a390c40d2 Improved latch profiling, especially for loadPage. 2006-08-04 23:45:27 +00:00
Sears Russell
c413203ec8 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.
 2006-07-29 00:56:54 +00:00
Sears Russell
783d1d6ffd Removed the fixed page initialization operations, which weren't being used, and were a slow hack anyway. There is now a more-general (and efficient) 
implementation in alloc.c

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.

e33319175f Fixed some cht bugs. Abort is flakey. 2005-02-06 03:48:12 +00:00

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)

570dc16f70 - minor: hash_insert returns an error in case of memory allocation failure 2005-02-03 20:40:31 +00:00

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

a27787b2fa Cluster hash table now allows transactions to contain multiple requests. 2005-02-03 02:01:23 +00:00

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

1260710a27 Got rid of another broken hash implementation... 2005-01-31 01:34:29 +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
Sears Russell
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)

23539f446a More-or-less working version of CHT. Needs a lot of performance/stability/code cleanup work. 2005-01-19 00:51:54 +00:00

7dacf21069 Rearranged cht, moving some functionality into the 2pc library. Still 
need some test cases.

894e30085c libdfa ported to new hash table implementation. (Uses nested top actions.) 2005-01-15 23:55:49 +00:00
Sears Russell
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.
