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

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

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.

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

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?

2a9cb788a6 if LONG_TEST is defined, check for pinned pages on exit.

d26263262b Completely new blob implementation. Slower than the old one was supposed to be, but is correct, and extremeley 
simple.  It simply writes the pre-image and post-image of each blob to the log using TpageSet.

c8c9b7af19 the logger understands special record types. (At least partially...); shortened blob tests, since the blob

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
