f5e3ab2d91 concurrent hashtable seems to be working; still need to work out atomicity primitives (eg; options to leave the bucket locked on success) 2009-10-19 21:55:25 +00:00

 2009-08-14 06:31:13 +00:00

dd0bcae074 add thread synchronization logic to ensure that only one thread is performing writeback at a time. This fixes weird I/O interleavings on some machines 2009-08-13 23:18:49 +00:00
Sears Russell
0154f7d29d IMPORTANT API CHANGE: stasis_dirty_page_table_flush_range() no longer force writes to disk. You now need to call forcePageRange() after flush page range returns. 
This commit should significantly improve sequential write thoughput.

I found a segfault bug this morning, but cannot reproduce.  Could be a heisenbug, or could have been a hardware fault (gojira repeatedly kernel paniced, then both problems went away...)

0cc65aefaf Remove LRU-ordered writeback. Instead, writeback pages sequentially once some fraction of the page file is dirty. Also. further simplifies writeback code. 2009-08-11 17:23:43 +00:00
Sears Russell
907a24b68e dirty page table flush was pinning pages, then asserting they were not pinned; updated page writeback api to allow correct usage 2009-08-08 01:43:03 +00:00
Sears Russell
c92ee87c32 improved behavior for sequential I/O performance, fixed races during writeback 2009-08-07 18:27:52 +00:00

9ef3adf40c - Fix compile warning + broken fcn pointer from last commit. 
- Address crashes in Tupdate() and recovery caused by mixing segments and page oriented recovery  (add loadPageForOperation() call)
 2009-07-16 03:05:32 +00:00
Sears Russell
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
Sears Russell
eb0661ceeb added segment.c 2009-07-09 21:09:36 +00:00

Sears Russell
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

Sears Russell
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

73c4b4fb71 Fix for Issue 1. Reworked log format so that nested top actions do not need to look up old entries during forward operation. This saves log bandwidth and avoids the bug that caused the performance regression 2009-05-14 21:28:09 +00:00
