99bcf8acd9 Randomized test; bugfixes 2007-01-25 22:38:22 +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.

4e4461a193 check.h contains the work "end", which is #defined by the compenstaion stuff; moved check.h to be the first include. 2006-11-22 05:05:58 +00:00
Sears Russell
3c3ccd9df7 Uncommented the file and memory tests. 2006-11-22 05:03:32 +00:00
Sears Russell
4520f672ac The test sometimes calls append, append, truncate, where the first append terminates after the append, and returns EDOM. Check for this, and allow the test to pass. 2006-11-21 06:49:16 +00:00

cb90e015a1 Fixed printf warnings 2006-11-10 19:32:44 +00:00

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
Sears Russell
faf55911df Added non-blocking io implementation. It doesn't actually work yet, but it passes the unit tests. ;) 2006-10-26 05:48:30 +00:00
Sears Russell
10b77729f5 Simple (blocking, poor truncation performance) file handle implementation. 2006-10-18 00:57:36 +00:00

e81bf95553 Added a 10 minute timeout. 2006-10-07 00:26:18 +00:00
Sears Russell
1575d97a6b Fixed recovery bug. TregionDealloc was being called during redo(), causing an assert to fail. Without the 
assert, would have gone into infinite recursion.
 2006-10-05 22:08:42 +00:00
Sears Russell
a3e3ad2453 Added a 20 minute timeout to prevent deadlocks and other problems from blocking the test. 2006-10-05 01:00:10 +00:00

Sears Russell
f74df8a0fe Test is more stringent now; it runs in roughly the same amount of time 
becase pageFile.c is no longer using O_DIRECT.
 2006-08-10 23:35:21 +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
78f7b5a12e Added tests for concurrent transactions + aborts(). Still doesn't test 
latching, as it is single threaded.
 2006-07-27 00:16:24 +00:00

c8c9b7af19 the logger understands special record types. (At least partially...); shortened blob tests, since the blob 
implementation is fundamentally broken, and slow
 2006-06-20 23:02:27 +00:00

e14877821f Fixed blob bug. The reason it's so slow is that it's logging a preimage + postimage of each blob and then synchronously writing to a second copy each time the blob is 
written to(!!!)

1d9f7b314f Added -fno-strict-aliasing to the CFLAGS for the unit tests... This is 
easier than making all this code -O2 clean...  (The rest of lladd now

tradeoff...)

c1d8906d28 removed memcpy() calls from inMemoryLog; added "const" qualifier to many LogEntry pointers. 2006-04-11 02:20:21 +00:00
Sears Russell
7decae7172 All tests that pass with LOG_TO_FILE now pass with LOG_TO_MEMORY, but LOG_TO_MEMORY is slow, and seems to be 
killing malloc's performance for some reason.  (linearHashNTA spends many seconds in free() between unit
tests...)
 2006-04-08 00:05:09 +00:00

ee9eb416ea Implemented fifo pool that allocates entries out of a pool (it should be easy to extend this to avoid deadlock, while allowing it to continue to provide backpressure) 2005-03-23 08:07:53 +00:00

Sears Russell
84a20a3c96 Started adding error handling code to LLADD. 2005-02-16 04:11:14 +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

2ac1302062 Recovery now supports the lock manager. (And vice-versa ;) 2005-02-10 21:56:32 +00:00
Sears Russell
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

b2b0e8a9d4 - test_list2.c now issues a secondary init/shutdown sequence, just to make

 2005-02-08 08:05:24 +00:00

1260710a27 Got rid of another broken hash implementation... 2005-01-31 01:34:29 +00:00
Sears Russell
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
Sears Russell
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

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

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.

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
Sears Russell
360f0d15e2 Working, non-concurrent linear hash and linked list implementations. 
The idea is to implement the non-concurrent versions, and then convert
them to concurrent versions using nested top actions.

Sears Russell
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.

Sears Russell
811bc5c710 Implemented a freespace manager that should safely allocate space, even in the face of crashes, and can reclaim unused space (unless an application opens more than one simultaneous transaction that performs allocations) 
Fixed some blob bugs (by adding extra fdatasync() calls).

Began factoring out the page management code so that it is an extenstion, and a less integral part of lladd.

Sears Russell
961b63af15 Rewrote / refactored page.h. Now, it uses a freelist to reclaim slotid's within a page, and is implemented as two seperate modules. The first handles lsn's, and (will soon) check the type of each page, and then delegate work to a particular implementation of the second module. 2004-07-30 01:28:39 +00:00

54ba9b0347 Refactored bufferMananger / pageCache, so that bufferMananger handles loading an unloading pages, and pageCache only implements the replacement policy. 
Also, used memprof to detect and remove all memory leaks (at least all memory leaks that are encountered by check_transactional2), and fixed a number of misuses of the pblHash.

Sears Russell
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
