16 check-ins using file src/btree.c version 61d96c2e

2014-11-03
18:03
Updates to the sqlite3_stmt_scanstatus() documentation. No changes to code. (check-in: d97c324e user: drh tags: trunk)
16:56
Add the experimental sqlite3_stmt_scanstatus() API. For comparing the number of rows actually visited by a loop with the estimate used by the query planner. (check-in: ab3b0fc5 user: dan tags: trunk)
16:39
Fix a typo preventing this from building with SQLITE_ENABLE_STMT_SCANSTATUS defined. (Closed-Leaf check-in: 4c5714ab user: dan tags: scanstatus)
16:35
Refactor the interface to make it more easily extensible. (check-in: 7955342d user: drh tags: scanstatus)
15:33
Add further tests. Fixes so that compilation without ENABLE_STMT_SCANSTATUS works. (check-in: a2303c71 user: dan tags: scanstatus)
14:46
Use exponential buffer size growth in StrAccum, as long as the size does not grow to large, to avoid excess memory allocation resize operations. Also, document the fact that setting scratch memory causes SQLite to try to avoid large memory allocations. (check-in: a518bc33 user: drh tags: trunk)
13:24
When enlarging the size of a StrAccum object, use sqlite3DbMallocSize() to record the entire size of the allocation, not just the requested size. (check-in: 3dda3c93 user: drh tags: trunk)
11:25
Remove unused variable from struct WhereInfo. Add some explanatory comments to new code. (check-in: f5313e0c user: dan tags: scanstatus)
2014-11-01
21:00
Minor performance enhancements to SQLITE_ENABLE_STMT_SCANSTATUS code. (check-in: f13d6ba8 user: dan tags: scanstatus)
20:38
If SQLITE_ENABLE_STMT_SCANSTATUS is defined, record the number of times each VDBE opcode is executed. Derive the values returned by sqlite3_stmt_scanstatus() from these records on demand. (check-in: 9ea37422 user: dan tags: scanstatus)
18:32
Add requirements marks and make minor tweaks to documentation. (check-in: 49188b2b user: drh tags: trunk)
18:08
Minor fixes and documentation improvements for sqlite3_stmt_scanstatus(). (check-in: 8d8cc960 user: dan tags: scanstatus)
2014-10-31
20:11
Add the experimental sqlite3_stmt_scanstatus() API. (check-in: 6a9bab34 user: dan tags: scanstatus)
14:53
Merge recent trunk enhancements, and in particular the improvements to the b-tree balancing logic, into the sessions branch. (check-in: 28b044a5 user: drh tags: sessions)
14:46
Change the command-line shell man-page to use the ".tr" troff directive instead of ".cc" for escaping the initial "." characters in the ".help" output. (check-in: 67f0d469 user: drh tags: trunk)
14:26
Simplify the logic in the cell redistribution loop of balance_nonroot(). Enhance and clarify comments and add assert() statements for additional verification of correctness. (check-in: a07078b6 user: drh tags: trunk)
