97a2fdd600 fix null pointer dereference when recovering loser transaction that makes use of multipage operations 2010-05-19 01:22:40 +00:00

71292538e8 Amortize bucket initialization costs for linear hash tables. The best case improvement (~ 20%) is seen with hashes with fixed length key/value pairs and insert-only workloads 2010-05-12 17:51:20 +00:00

dc1f799a37 TarrayListAlloc() and TarrayListExtend() now generate O(1) bytes of log entries; they use the new multipage operation type. 2010-05-11 23:34:13 +00:00

74803d354e fix latch ordering in concurrent buffer manager. It no longer does a lock(p->loadlatch) while holding a hashtable bucket latch. Instead, it trylocks, then compensates for in progress changes if the latch fails. 2010-04-23 23:51:12 +00:00

87ba38adb7 fix compilation when CONCURRENT_LRU is defined; make it the default (since it is only used by concurrentBufferManager) 2010-04-20 03:56:47 +00:00

c7fa929e71 This fixes in Stasis issue 22. 
Replacement policies now track the pin count of each page that they interact with.  This behavior used to live in bufferHash, and had never been ported to concurrentBufferManager.

For various reasons, the pin counts have to be updated atomically with the LRU state.  This would be very difficult to do inside of concurrentBufferManager, which sometimes needs to add and remove pages to replacement policies without holding any other latches.

358f037441 fix concurrency bug that cropped up when the concurrent buffer manager was used with the concurrent wrapper replacement policy. Concurrent wrapper hashes on pageid, but the buffer manager was changing the pageid out from under it 2010-03-31 22:39:07 +00:00
Sears Russell
d281282533 fix concurrentWrapper so that it implements the same api as the other replacement policies (it used to livelock when no pages were available. It now returns null). 2010-03-31 22:37:42 +00:00

5ffd1110e9 Added concept of "transaction fingerprints" 
The region allocator marks freed regions "Condemned" before actually freeing them.  Condemned regions are associated 
with a transaction; before they can be reused / coalesced the transaction that condemned them must complete.

The region allocator used "TisActiveTransaction(xid)" to determine whether a given transaction had completed.  The 
problem is that Stasis now reuses transaction id's, and condemned regions were never reclaimed in practice.  A transaction
fingerprint is a unique identifier (currently transaction id, rec_lsn) that can be used to distinguish transactions that
did not execute concurrently.

I considered an alternative design based upon end-of-transaction actions.  This would have worked as well, but would 
have been a more invasive change.

b44f8b17b3 Add getCachedPage() call. This allows dirtyPageTable to write back pages with out accidentally reading them back in from disk with loadPage(). This should improve performance and allow loadPageOfType() to be used safely. 2009-07-14 07:46:47 +00:00
Sears Russell
4493dbb88b Added support for segment based recovery. For now, Stasis doesn't support hybrid recovery, so mixing page deallocation and segments will make recovery corrupt data / segfault. 2009-07-13 17:18:01 +00:00
Sears Russell
d6c91241d6 fixed bug that caused loadPageOfType to ignore type parameter. Recovery is still broken, since it calls loadPage, even when it can't 2009-07-10 01:19:44 +00:00

2593de7a2c Move page type to Page_s struct. This breaks indirect.c (which is poorly thought out, and will be removed shortly), and was the next step on the road to segment-based recovery 2009-07-07 19:20:22 +00:00

120665ae53 cleaned up arrayList. stasis_record_write no longer takes an LSN (it was ignoring it anyway). Added some missing calls to stasis_page_lsn_write (each time a page is written to, stasis_page_lsn_write should be called; this happens automatically for operations called via tupdate 2009-06-02 18:25:35 +00:00
