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

1a60582a0c Added function to handle code that allocates data without first consulting the allocationPolicy 2006-08-11 03:01:16 +00:00

8faf045e7d Fixed numerous bugs in allocationPolicy.c and alloc.c 
allocationPolicy.c was not handling deallocations correctly
Tdealloc() was not calling interpretRid() on its input before passing it into the allocationPolicy
Added locking support for TallocFromPage()

appropriate.

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.

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.

7847331771 Minor cleanup, added ability to calculate the global average number of 
buckets traversed per find().  Added a warning for code that actually
relies upon PBL's way of interpreting insert.

f74df8a0fe Test is more stringent now; it runs in roughly the same amount of time 
becase pageFile.c is no longer using O_DIRECT.

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

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.

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

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

a3d0f6f6f5 Added support for concurrent transactions (by using nested top actions). 2006-07-27 00:15:29 +00:00
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.
