50 check-ins occurring around a47efb7c8520a011.

2017-04-14
12:39
Simplify the interface to the subst() routines that are part of the query flattener by collecting common parameters into the SubstContext object and passing around a pointer to that object. (check-in: e651074be2 user: drh tags: trunk)
12:27
Remove an incorrect ALWAYS(). (check-in: f956f6ae6b user: drh tags: trunk)
00:45
Fix a couple of unreachable branches. (check-in: 1aa0ea8db7 user: drh tags: skip-ahead-distinct)
2017-04-13
21:29
Fix the skip-ahead-distinct optimization so that it works with indexes that have repeated columns with different collating sequences. (check-in: ce1e2b8877 user: drh tags: skip-ahead-distinct)
19:48
Simplification of the skip-ahead-distinct logic. There is still an issue with handling COLLATE. (check-in: 57c5173b63 user: drh tags: skip-ahead-distinct)
18:33
New test cases and minor fixes for the optimization on this branch. (check-in: 70ac9ea1a6 user: dan tags: skip-ahead-distinct)
16:19
Update this branch with latest changes from trunk. (check-in: 5fcd840cf9 user: dan tags: schemalint)
15:51
Reinstate the SQLITE_API qualifier on the sqlite3_delete_database() method in test_delete.c. Accidentally removed by the previous commit. (check-in: 59c70108fd user: dan tags: trunk)
15:36
Update the code in test_delete.c to use the "win32" VFS if SQLITE_OS_WIN is defined. (check-in: fa9bb7b768 user: dan tags: trunk)
13:01
Only use the skip-ahead-distinct optimization if the index has been analyzed and we know that a skip-head is likely to skip over at least 11 rows. The magic number 11 was determined by experimentation. (check-in: 0cf16decd5 user: drh tags: skip-ahead-distinct)
09:45
Allow a user column name to be used on the LHS of a MATCH operator in FTS5. (check-in: 6f54ffd151 user: dan tags: trunk)
01:19
Forward port the skip-ahead-distinct branch which was abandoned for some reason that I do not recall. This port should have been achived by a merge of trunk into the previous head of skip-ahead-distinct, but that did not work. So I had to manually "rebase" the changes. (check-in: 132339a1fb user: drh tags: skip-ahead-distinct)
00:12
Fix a regression caused by the fix for ticket [6c9b5514077fed34551f98e64c09a1] - control characters allowed in JSON. (check-in: 8e7b611863 user: drh tags: trunk)
2017-04-12
17:50
Update fts5 to support "<colset> : ( <expr> )" for column filtering, as well as "<colset> : NEAR(...)" and "<colset> : <phrase>". (check-in: c847543f8b user: dan tags: trunk)
17:38
Improved \n and \r escapes in the ext/misc/dbdump.c utility function. The implementation of dbdump.c now matches the implementation in the CLI. (check-in: f2643315bb user: drh tags: trunk)
2017-04-11
20:48
Avoid updating unaffected indexes on a table as part of an UPDATE that requires foreign key processing in some cases. (check-in: 7aae5c0f99 user: dan tags: trunk)
19:58
Avoid updating unaffected indexes on a table as part of an UPDATE that requires foreign key processing in some cases. (Closed-Leaf check-in: 477bea9ed0 user: dan tags: fkey-optimization)

Update this branch with latest trunk changes. (check-in: 0f66a09393 user: dan tags: schemalint)
18:55
Limit the depth of recursion for valid JSON in the JSON1 extension in order to avoid using excess stack space in the recursive descent parser. Fix for ticket [981329adeef51011052667a9]. (check-in: 1f68c18459 user: drh tags: trunk)
18:29

Smaller and faster implementation of exprMightBeIndexed(). (check-in: 76cd611d41 user: drh tags: trunk)

16:44
Very slight smaller and faster sqlite3SelectNew() (check-in: 4143650c4c user: drh tags: trunk)
12:20
Add an ALWAYS() around an unreachable condition in sqlite3VdbeMemGrow(). (check-in: 0f3eb61f44 user: drh tags: trunk)
11:52
Fix a segfault that could occur if an indexed expression was used in a comparison operation within the result-set of a SELECT statement. (check-in: d6bb7c42ff user: dan tags: trunk)
01:30
When evaluating a query that uses an index on an expression, try to use the expression values read directly from the index rather than reevaluating the expression. (check-in: a47efb7c85 user: drh tags: trunk)
01:01
Improved comments. Fix a problem when an indexed expression is used in an ORDER BY clause. (Closed-Leaf check-in: c59eaf2b7c user: drh tags: covering-index-on-expr)
2017-04-10
23:42
Merge changes from trunk. (check-in: 8978465f33 user: drh tags: covering-index-on-expr)
20:51
Smaller and faster vdbeFreeOpArray() (check-in: e052436d9f user: drh tags: trunk)
20:27
Slightly smaller and faster sqlite3VdbeMemGrow(). (check-in: efd1702ae8 user: drh tags: trunk)
20:00
Add ext/expert/README.md. (check-in: 9318f1b9ed user: dan tags: schemalint)
16:13
Changes to allow the code in sqlite3expert.c to be tested directly (via the API in sqlite3expert.h) instead of by invoking the sqlite3_expert application. Fix memory leaks and other problems. (check-in: 5dd9831721 user: dan tags: schemalint)
12:31
Add a new JSON test case to verify that all control characters are escaped in the json_quote() function. (check-in: 6ee12221fa user: drh tags: trunk)
12:25
Change the JSON extension so that it disallows control characters inside of strings. Fix for ticket [6c9b5514077fed34551f98e64c09a10dc2fc8e16]. (check-in: 475d8f82ec user: drh tags: trunk)
2017-04-09
19:23
Do not expose the name of the internal Mem object in the public interface defined by sqlite3.h. (check-in: 19dd753f9e user: drh tags: trunk)
08:38
Fix the -file option on the sqlite3_expert program. (check-in: 0857c48e02 user: dan tags: schemalint)
2017-04-08
19:00
Merge latest trunk with this branch. (check-in: e051e8f21b user: dan tags: schemalint)

18:24
Merge all recent changes from trunk. (check-in: c23ef5e231 user: drh tags: apple-osx)
18:18
Disallow leading zeros on numeric constants in JSON. Fix for ticket [b93be8729a895a528e2] (check-in: 204e72f008 user: drh tags: trunk)
17:41
Use hash tables instead of in-memory database tables for a few purposes in sqlite3expert.c. (check-in: bf10e68d9e user: dan tags: schemalint)
14:11
Expand on the comment above OP_Destroy to explain why it throws an error if there are any active reader VMs. (check-in: b9a8c2b9be user: dan tags: trunk)
13:52
Have the rtree module close any open blob-handle within the xSavepoint method. This prevents such an open blob handle from interfering with DROP TABLE operations. (check-in: fa4416adc2 user: dan tags: trunk)
13:42
Fix the quoting mechanism for ".dump" so that it is not applied for the ".mode quote" output. (check-in: 78c1e90305 user: drh tags: trunk)
09:12
Have fts5 close any open blob-handle when a new savepoint is opened. This ensures that fts5 does not prevent DROP TABLE statements (which always open a savepoint) from succeeding. (check-in: a921ada890 user: dan tags: trunk)
01:09
Make sure the RTree sqlite3_blob handle is reset prior to renaming the table. (check-in: 1cdae2db3c user: drh tags: trunk)
00:55
Fix the ".dump" command so that it works with ".headers on". Also fix the display of ".mode insert" with ".headers on". (check-in: a6ce57ee3c user: drh tags: trunk)
00:25
Merge the latest trunk changes. (check-in: dd16439ea1 user: drh tags: apple-osx)
2017-04-07
20:20
Use replace() instead of char() to quote newline and return characters in strings in the output of .dump, to avoid excess expression complexity. (check-in: 7307352988 user: drh tags: trunk)
20:14
Refactor code to suggest indexes from the shell tool into an extension in ext/expert. Unfinished. (check-in: 305e19f976 user: dan tags: schemalint)
