01:57
Change the weighting of binary searches on tables to 1/10th the cost of a search on an index. Change the assumed reduction in search space from a indexed range constraint from 1/3rd to 1/4th. Do not let the estimated number of rows drop below 1. check-in: 4847c6cb user: drh tags: stat2-enhancement

2011-01-26
19:46
Update all built-in VFSes to return SQLITE_OK for the SQLITE_FCNTL_SYNC_OMITTED file-control operation. Also change the xFileControl methods to return SQLITE_NOTFOUND for unrecognized operation codes. check-in: 6f2c72a0 user: drh tags: trunk
15:23
Update test file mutex1.test to account for [e3b500fb5d]. check-in: c86e46f4 user: dan tags: trunk
13:28
More mutexes around another sqlite3StatusAdd() call. check-in: e3b500fb user: drh tags: trunk
13:24
Add a mutex around an sqlite3StatusAdd() call to prevent the pagecount overflow measurements from getting off in multithreaded applications. check-in: 3d8b298d user: drh tags: trunk
07:25
Update mutex1.test so that it works with the memsubsys1 permutation (pagecache memory). Change a few instances of SQLITE_MUTEX_STATIC_LRU2 in comments and test code to STATIC_PMEM. check-in: 456bd5c6 user: dan tags: trunk
06:13
Changes to exclusive2.test to make it more deterministic. check-in: 84b0c2bc user: dan tags: trunk
00:07
Rename the PCache1.mxPinned field to n90pct (since it is 90% of nMax) in order to distinguish it from PGroup.mxPinned. Fix the computation of n90pct so that it does not overflow adversely on excessively large cache sizes. check-in: c85202ba user: drh tags: trunk

16:20
Change the name of SQLITE_FCNTL_SYNC to SQLITE_FCNTL_SYNC_OMITTED and only send it when PRAGMA synchronous=OFF. Add better documentation to explain what that file-control opcode is used for. check-in: 64914980 user: drh tags: trunk

Restructuring and generalizing analyze5.test. The whole script is currently disabled and will need to be reenabled prior to merging with trunk. check-in: 31fcc706 user: drh tags: stat2-enhancement

Ensure that if a deferred FK constraint is violated by a statement that creates its own implicit transaction, the statement is not an "active-write" after sqlite3_step() returns. Closed-Leaf check-in: 8063197e user: dan tags: deferred-fk-quirk

Change the cost estimator in the query planner to take into account the logN rowid lookup cost when going from an index to a table. check-in: b442525b user: drh tags: stat2-enhancement
2011-01-22
13:32
Modify the trace callback mechanism so that SQL commands executed from within virtual table or user function callbacks are passed to the trace callback without parameter expansion and enclosed in SQL comments. check-in: a764915b user: dan tags: trunk
00:10
Add the ability to use indices for constraints of the form "x IS NOT NULL" when sqlite_stat2 is available and most entries for column x are NULL. check-in: 5d5bddd2 user: drh tags: stat2-enhancement
2011-01-21
18:25
Change sqlite3StrAccumAppend() to use realloc instead of malloc. check-in: 380f61df user: dan tags: trunk

Adjustments to the result row estimator for the IN operator so that it gives the same estimates as the equivalent OR operator. Test cases for the same. check-in: c82cb9c0 user: drh tags: stat2-enhancement
16:27
Make use of histogram data to make better estimates for the number of rows that will be returned from "x IN (v1,v2,v3,...)" constraints. check-in: fd3977a2 user: drh tags: stat2-enhancement
15:52
Add options to test command [do_faultsim_test] to support testing VFS implementations. check-in: 503ad889 user: dan tags: trunk

Update ANALYZE test cases to check out the use of histograms for equality constraints. check-in: c7b59afa user: drh tags: stat2-enhancement

Comment improvements in pcache1.c. No changes to code. check-in: 9660a0a2 user: drh tags: trunk
2011-01-18
17:03
Do not use mutexes in the pcache implementation unless SQLITE_ENABLE_MEMORY_MANAGMENT is defined. This is a performance enhancement. A side effect is that pcaches will not steal pages from one another unless ENABLE_MEMORY_MANAGEMENT is set, or unless SQLITE_THREADSAFE=0. check-in: e5ca59e6 user: drh tags: trunk
16:13
Get all test cases working with the mutex-free-pcache implementation. Closed-Leaf check-in: 2dc98d29 user: drh tags: mutex-free-pcache
15:17
Do not use SQLITE_MUTEX_STATIC_MEM2 since it has been reused as STATIC_OPEN. Instead, create a new static mutex STATIC_PMEM which is an alias for the unused STATIC_LRU2. check-in: f1cf02ef user: drh tags: mutex-free-pcache
2011-01-17
21:32
Here is a completely new implementation of the mutex-free-pcache. This one uses a common code base and automatically selects whether or not to use mutexes depending on compile-time and start-time options. check-in: d094a1bf user: drh tags: mutex-free-pcache
18:30
Fix a typo in the documentation for sqlite3_stmt_readonly(). check-in: 56417a33 user: drh tags: trunk
17:42
Add the SQLITE_OMIT_AUTORESET compile-time option which if enabled causes the sqlite3_step() routine to return SQLITE_MISUSE if it is called after it has previously returned anything other than SQLITE_ROW, SQLITE_BUSY, or SQLITE_LOCKED. check-in: 053ce76d user: drh tags: trunk
02:24
Add back an ALWAYS() to regain full test coverage. check-in: b93f6f3e user: drh tags: trunk

Fix a couple of crashes in fts3 that can occur if the database contents are inconsistent. check-in: 811e12cd user: dan tags: trunk
10:58
Fix a segfault that can occur in matchinfo if an fts4 table contains mostly zero-length documents. Specifically, if the table contains more rows than it does bytes of text. check-in: fe904766 user: dan tags: trunk
2011-01-12
17:56
Do not raise an SQLITE_CORRUPT error in Recoverymode if the database size in the header is larger than the physical file size. This facilitates recovery of a database in which the database size field has been corrupted. check-in: 114640d9 user: drh tags: trunk

Merge accidentally created fork. check-in: b7d080b8 user: dan tags: trunk
