47 check-ins using file src/sqliteInt.h version 37628fe3

2016-11-11
19:01
Enhance the OP_IdxInsert opcode so that it can used unpacked key values if they are available. Update the code generator to take advantage of this new capability. The speedtest1.c test is about 2.6% faster as a result. Later: This also introduced bug [30027b613b]. Bummer. (check-in: 925840cf user: drh tags: trunk)
18:19
Remove obselete and unused logic in the update code generator. Fix the sqlite3BtreeMovetoUnpacked() routine so that it remembers the rowid of the row that it landed on. (Closed-Leaf check-in: 1a587d72 user: drh tags: unpacked-IdxInsert)
17:52
Merge enhancements and bug-fixes from trunk. (check-in: 5515b827 user: drh tags: unpacked-IdxInsert)
17:08
Fix a problem with switching from wal to rollback mode when SQLITE_DBCONFIG_NO_CKPT_ON_CLOSE is configured. (check-in: 46e00162 user: dan tags: trunk)
16:33
Add the test/ossfuzz.c interface adaptor for OSS-FUZZ. Make previsions for testing the adaptor using fuzzcheck.c. (check-in: 119d6ef8 user: drh tags: trunk)
15:49
Handle some obscure "row value misused" cases that could cause segfaults or assertion failures. (check-in: fba5fddb user: dan tags: trunk)
14:54
Back out the "--raw" option on ".read" in the command-line shell. Instead, fix the command-line shell so that if EOF is reached without seeing a final semicolon, it goes ahead and passes the accumulated SQL text to SQLite. (check-in: f98c8ac8 user: drh tags: trunk)
09:51
Add extra tests for the xBestIndex() virtual table method. (check-in: 642a8fba user: dan tags: trunk)
05:19
In the command line shell, avoid using utf8_printf() in a couple places where it is superfluous. (check-in: 6311a8bd user: mistachkin tags: trunk)
04:37
Add the --raw option to the ".read" dot-command of the command-line shell, to cause the named file to be read and sent directly into sqlite3_exec() without any interpretation. (check-in: 09233770 user: drh tags: trunk)
03:37
Take care not to try to generate code for the ATTACH and DETACH commands if there were syntax errors during parsing. Fix for ticket [2f1b168ab4d4844] (check-in: b0ff183b user: drh tags: trunk)
2016-11-10
21:19
Break up the sqlite3BtreeMovetoUnpacked() routine into an eponymous routine and sqlite3BtreeMovetoIntkey(). Each routine specializes in a single kind of btree. (Leaf check-in: 9a64a4f2 user: drh tags: split-moveto)

Avoid a few unnecessary calls to sqlite3BtreeMovetoUnpacked(). (check-in: eac0e827 user: drh tags: unpacked-IdxInsert)
17:01
When doing a REPLACE on a WITHOUT ROWID table with no secondary indexes, bypass the OP_NoConflict/OP_Delete sequence and directly overwrite any preexisting row, for a performance increase. (check-in: f7041cbb user: drh tags: unpacked-IdxInsert)
16:07
Remove C++ style comments. No code changes. (check-in: 42f8aa62 user: drh tags: unpacked-IdxInsert)

2016-11-09
20:14
Comment changes that attempt to better explain the behavior of the "seekResult" field on VdbeCursor objects and the seekResult parameter to sqlite3BtreeInsert() and the OPFLAG_USESEEKRESULT flag on insert opcodes. No changes to code. (check-in: 345b46be user: drh tags: unpacked-IdxInsert)
16:03
Fix a simple comment typo. No changes to code. (check-in: 51d0aed8 user: drh tags: unpacked-IdxInsert)
01:46
Fix typo in the CSV extension. (check-in: b4889588 user: mistachkin tags: trunk)
01:38
Make use of the unpacked key on the OP_IdxInsert on sorters with a LIMIT. (check-in: 42db7cd2 user: drh tags: unpacked-IdxInsert)
01:19
Fix a typo on the OP_IdxInsert documentation. No code changes. (check-in: e4acd982 user: drh tags: unpacked-IdxInsert)
01:07
Add a DISTINCT query to speedtest1.c. Also change INSERT OR REPLACE into just REPLACE. (check-in: 754ee844 user: drh tags: trunk)
00:57
Remove the "experimental" marking from the sqlite3_preupdate interfaces. But be sure all the interface definitions are within documentation. (check-in: d6dd2ad3 user: drh tags: trunk)
00:10
Enhance the OP_IdxInsert opcode to optionally accept unpacked key material. (check-in: 89d958ab user: drh tags: unpacked-IdxInsert)
2016-11-08
19:22
Avoid superfluous cursor seeks in "INSERT OR REPLACE" statements. (check-in: bec5b6d4 user: dan tags: trunk)
17:19
Avoid generating OP_TableLock unnecessary instructions on btrees that are not sharable. (check-in: 8cb8516d user: drh tags: trunk)
16:27
Fix the speedtest1.c test program so that it gives closing "%" wildcards on LIKE searches. (check-in: c2f84f63 user: drh tags: trunk)
00:30
Tweaks to speedtest1.c to better reflect mobile usage based on findings in the "Pocket Data" paper by Kennedy, Ajay, Challen, and Ziarek. (check-in: b5733cae user: drh tags: trunk)
2016-11-07
18:18
Fix OOM error reporting in the json1_group_object() SQL function. Remove an unreachable branch from the JSON1 logic. (check-in: b5409849 user: drh tags: trunk)
15:15
Replace some unreachable branches from the JSON1 extension with assert(). (check-in: 145cd13e user: drh tags: trunk)
