23:23
Improve the performance of the ANALYZE command by taking advantage of UNIQUE constraints on indices. check-in: 114dcf33 user: drh tags: trunk

Correct help text and make consistent use of snprintf. check-in: 9c424a5c user: mistachkin tags: asciiMode
22:41
Fix a bug in the whereRangeSkipScanEst() procedure (added by check-in [d09ca6d5efad3e4cfa]) where it fails to consider the possibility of a ROWID column when computing the affinity of a table column. check-in: 6aea2258 user: drh tags: trunk

19:54
Avoid change tests when analyzing single-column unique indexes after getting past the initial NULL entries. check-in: 4690e99c user: drh tags: faster-analyze

16:23
Merge recent trunk changes into the sessions branch. check-in: a9db017e user: drh tags: sessions

Add the readfile(FILENAME) and writefile(FILENAME,CONTENT) SQL functions to the command-line shell. check-in: fb1048cb user: drh tags: trunk
12:19
Add support for hexadecimal integer literals in the parser. check-in: f8f79f28 user: drh tags: trunk
12:09
In the command-line shell, in CSV output mode, terminate rows with CRNL but do not expand NL characters in data into CRNL. Provide the extra -newline command-line option and the extra argument to .separator to designate an alternative newline character sequence for CSV output. check-in: 16c8ce10 user: drh tags: trunk
2014-07-23
23:57
Add experimental "costmult" logic. Only enabled when compiled with -DSQLITE_ENABLE_COSTMULT. check-in: 729ece40 user: drh tags: trunk
19:37
Ugh. Consecutive UNIQUE index entries are only distinct if the index is on NOT NULL columns. So the previous version was not quite right. This check-in fixes the problem. check-in: 30033f96 user: drh tags: faster-analyze
19:04
Enhancements to the hex literal tests. Closed-Leaf check-in: a3cc027f user: mistachkin tags: hex-literal
18:36
Improve the performance of the ANALYZE command by taking advantage of the fact that every row of a UNIQUE index is distinct. check-in: 3e1e79e1 user: drh tags: faster-analyze
15:51
Updated documentation on sqlite3_temp_directory. No changes to code. check-in: e6225a7b user: drh tags: trunk
14:52
Remove a surplus function prototype. #ifdef code that is not used when hex integers are omitted at compile time. check-in: a5b383e0 user: drh tags: hex-literal
13:40
Change the hex literal processing so that only the SQL parser understands hex literals. Casting and coercing string literals into numeric values does not understand hexadecimal integers. This preserves backwards compatibility. Also: Throw an error on any hex literal that is too big to fit into 64 bits. check-in: 6c6f0de5 user: drh tags: hex-literal
02:07
Casting hex literals directly from string to float always results in a positive number. check-in: 4b86ccdf user: drh tags: hex-literal
01:59
Reformatting a few test cases for clarity. check-in: 7e1bbacb user: drh tags: hex-literal
01:56
Test cases for hex literals. check-in: 19054339 user: drh tags: hex-literal
01:26
Add support for parsing C-style hexadecimal literals. check-in: 34a1f38b user: drh tags: hex-literal
2014-07-22
22:46
When running ANALYZE, it is not necessary to check the right-most key column for changes since that column will always change if none of the previous columns have. check-in: 48f40861 user: drh tags: trunk
20:02
Add the OP_ReopenIdx opcode that works like OP_OpenRead except that it becomes a no-op if the cursor is already open on the same index. Update the OR-optimization logic to make use of OP_ReopenIdx in order to avoid unnecessary cursor open requests sent to the B-Tree layer. check-in: 77f412ca user: drh tags: trunk
19:14
The optimization of check-in [b67a6e33f2] does not work (it generates incorrect VDBE code) if an OR term is AND-ed with a constant expression. So back that optimization out and add a test case to make sure it does not get added back in. check-in: eed754fe user: drh tags: trunk
16:00
Fix the index name for the shadow tables in the spellfix1 extension so that multiple instances of the spellfix1 virtual table can each have their own index. check-in: 438c348a user: drh tags: trunk
15:33
Correction: The maximum SQLITE_MAX_ATTACHED value to avoid overflowing a signed 8-bit integer is 125, not 127. check-in: 48e37802 user: drh tags: trunk
14:58
Enhance the sqlite_stat1.stat parsing to allow additional text parameters at the end. Unrecognized parameters are silently ignored. check-in: ca2a5a2c user: drh tags: trunk
14:42
Expire prepared statements after running ANALYZE. check-in: b083a961 user: drh tags: trunk
12:05
Enhance the comment on whereLoopAddBtree(). No changes to code. check-in: b22dd165 user: drh tags: trunk
00:40
For the OR-optimization, avoid generating OP_OpenRead opcodes that reopen exactly the same index. check-in: b67a6e33 user: drh tags: trunk
2014-07-21
20:07
Limit the maximum SQLITE_MAX_ATTACHED to 127, since a signed character is sometimes used to store the database index. check-in: f1c76c7c user: drh tags: trunk
15:44
Allow the SQLITE_MAX_ATTACHED compile-time option to be larger than 62. The default limit on the number of attached databases remains 10. check-in: 1a817ae2 user: drh tags: trunk
