26 check-ins using file src/shell.c.in version e0f0758b

2019-11-14
15:10
Minor documentation enhancements. No changes to code. check-in: 6153f3aa user: drh tags: hard-heap-limit
2019-08-23
21:11
Attempt to parse the NULLS LAST clause more efficiently. A few cycles were saved, but at the expense of more code. And there is a bug was introduced somewhere. Not worth continuing down this line. Closed-Leaf check-in: 12d2cf88 user: drh tags: dead-end
20:33
Move some things in parse.y so that TK_COLUMN and TK_AGG_COLUMN are assigned the same values as they are on trunk for a very small speedup. check-in: d26fdfa3 user: dan tags: nulls-last
17:09
Revise the VDBE comments for NULL-scan so that they also work make sense when reading a NULLS FIRST plan. check-in: bfe79378 user: drh tags: nulls-last
17:00
Additional simplifications of the WHERE loop code generator logic for NULLS LAST. check-in: 1383680d user: drh tags: nulls-last
16:12
Simplification of the WHERE loop code generator for NULLS LAST saves a few CPU cycles and about a hundred bytes of code space. check-in: e3ed2f49 user: drh tags: nulls-last
13:32
Invert the meaning of the regBignull flag so that it is 1 when doing the normal scan and 1 when scanning nulls. This enables the re-do jump at the bottom of the loop to be coded with a single OP_IfNotZero opcode, rather than a sequence of OP_If, OP_Integer, OP_Goto. check-in: bf875e1a user: drh tags: nulls-last
13:08
Extra VDBE comments in the NULLS LAST logic provide landmarks to help understand the EXPLAIN output. check-in: 649b08ea user: drh tags: nulls-last
2019-08-22
21:13
Add additional VDBE coverage macros. check-in: d3531f5b user: drh tags: nulls-last
19:35
Merge fixes from trunk. Also fix a reference to the KeyInfo.aSortOrder field, which should now be KeyInfo.aSortFlags check-in: 63e625c8 user: drh tags: nulls-last
16:38
Fix the likely(), unlikely(), and likelihood() functions so that they have no affinity, just like any other function. Ticket [7e07a3dbf5a8cd26] check-in: 44578865 user: drh tags: trunk
11:11
Fix a false-positive in sqlite3ExprNeedsNoAffinityChange(). Ticket [ac184eb571d5e6e0] check-in: e62eddbb user: drh tags: trunk
00:53
Fix the OP_SeekGE, OP_SeekGT, OP_SeekLE, and OP_SeekLT opcodes so that they preserve the datatype of the value in the register used as the key. Ticket [d9f584e936c7a8d0] check-in: 81b9f0f5 user: drh tags: trunk
2019-08-21
19:58
Add missing VdbeCoverage() macros to new code. check-in: b1cbcdc6 user: dan tags: nulls-last
17:46
Disable broken test case in expert1.test. check-in: 73e30c2e user: dan tags: nulls-last
15:41
Update this branch with latest trunk changes. check-in: 6153bcf4 user: dan tags: nulls-last
14:54
Avoid assuming that "column IS ?", where column is declared UNIQUE, matches only a single row (as "?" might be NULL). Fix for [b8689402]. check-in: d02490a2 user: dan tags: trunk
11:31
Fix a broken assert() in the fts3 snippet code that was failing for queries containging more than 64 phrases. check-in: 4c01e017 user: dan tags: trunk
2019-08-20
19:11
Fix a problem with fts5 "ORDER BY rank" queries when the fts5 table name requires quoting. check-in: 00e9a8f2 user: dan tags: trunk
17:14
Bring the hard-heap-limit branch up-to-date with trunk. check-in: 9b14eb77 user: drh tags: hard-heap-limit
14:43
Fix a segfault that could occur following an OOM while processing a SELECT statement for which one or more of the expressions in the window frame declaration are themselves sub-selects that use window functions. check-in: 75aec4fc user: dan tags: trunk
13:49
Add the new sqlite3_drop_modules() interface to the loadable extension mechanism. check-in: 658bd516 user: drh tags: trunk
11:43
Retain the affinity of an expression in a WHERE clause when it is transformed to a reference to an index column on the same expression. Fix for [f043b113]. check-in: 511da081 user: dan tags: trunk
02:19
Fix a typo and a harmless compiler warning. check-in: ec4c63e0 user: mistachkin tags: trunk
2019-08-19
20:44
Add the sqlite3_drop_modules() interface. check-in: e2c6fed8 user: drh tags: trunk
20:35
Omit the "_except" term from the name of the new interface. Closed-Leaf check-in: e5ba47c2 user: drh tags: sqlite3_drop_modules_except
