13 check-ins using file src/vdbeaux.c version be0797ca
|04:06||Avoid signed integer overflow when dealing with a LIMIT and OFFSET whose sum exceeds the maximum integer value. (check-in: c9bdf7ad user: drh tags: trunk)|
|00:14||In balance_nonroot, try to combine dropCell/insertCell combinations for the dividers into a cell overwrites. This results in a very small (0.05%) performance gain which is probably not worth the added complexity. (Closed-Leaf check-in: 478627c9 user: drh tags: failed-dropCell-opt)|
|19:42||When doing the sqlite3BtreeInsert() overwrite optimization, make sure the memcpy() does not extend off the end of the page. (check-in: 684ef458 user: drh tags: trunk)|
|18:09||Additional comments and an assert on the sqlite3BtreeInsert() overwrite optimization. (check-in: c1f0ae9d user: drh tags: trunk)|
|17:32||In sqlite3BtreeInsert() when replacing a re-existing row, try to overwrite the cell directly rather than deallocate and reallocate the cell. (check-in: 0b86fbca user: drh tags: trunk)|
|16:12||Fix an fts5 bug that could cause a crash following an OOM error or sqlite3_interrupt() interrupt. (check-in: 0ea3ece9 user: dan tags: trunk)|
|16:02||Avoid unnecessary zeroing of fields in the MemPage object that are going to be reinitialized before use anyhow. A smaller and faster binary results. (check-in: 01ada3d1 user: drh tags: trunk)|
|00:15||Fix an obscure problem in range estimation with STAT4. (check-in: 1f16c9a7 user: drh tags: trunk)|
|23:52||Fix the showstat4 utility program so that is displays strings using standard SQL notation (single quotes) rather than C-style notation. (check-in: 92998e4a user: drh tags: trunk)|
|19:04||Fix a minor error in the cg_anno.tcl script causing the cycles-per-file counts to be miscomputed. (check-in: b26df26e user: drh tags: trunk)|
|18:36||Update the tool/cg_anno.tcl script to give a summary of cycle counts by canonical source file name. (check-in: 254a83bf user: drh tags: trunk)|
|01:38||More changes to take advantage of the sqlite3VdbeAppendP4() method. (check-in: 83bc5e40 user: drh tags: trunk)|
|21:35||Add the sqlite3VdbeAppendP4() method for adding P4 content to the most recently coded instruction. (check-in: 28883e8f user: drh tags: trunk)|
