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

bb9e339823 changed to deal with new LinkedList api. 2006-10-28 03:31:27 +00:00

aa445bdfe5 slightly more general purpose; deals with longs instead of ints. 2006-10-28 03:30:45 +00:00

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

1575d97a6b Fixed recovery bug. TregionDealloc was being called during redo(), causing an assert to fail. Without the 
assert, would have gone into infinite recursion.

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

b615f0bc3e Towards 64-bit pageids. bufferManager can handle 64-bit offsets, but recordid.page is still 32 bit... 2006-08-11 19:31:42 +00:00

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.

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

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

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

Sears Russell
1988cf297d The "WARNING: Tdeinit() is aborting transaction %d" runtime message now 
lists the xid of the transaction it's aborting instead of "-1".

TisActiveTransaction(xid) now returns 0 for INVALID_XID.  Before the
output was undefined.

d1da4e59c0 Fixed segmentation fault when a CLR with a NULLRID is encountered. I 
don't understand why this bug wasn't triggered by linearHashNTA or
linkedListNTA, but is triggered by the new region implementation.

45a5996215 Documented subtle hack; TallocPage() really needs a way to set page type at recovery. Currently, this just doesn't happen, since page types are lazily set. 
Perhaps Talloc() could handle it?

d26263262b Completely new blob implementation. Slower than the old one was supposed to be, but is correct, and extremeley
