Ensure that sqlite3AuthRead() is only call for TK_COLUMN and TK_TRIGGER expression nodes. This fixes a harmless assert() identified by OSSFuzz. Move the assert() into a position where it is tested even if the authorizer is disabled. (check-in: d0c3beef user: drh tags: trunk)

2018-05-28
18:29
Do not require a statement journal in cases where REPLACE conflict handling is used to insert a single row, so long as the REPLACE operation cannot fire any triggers or foreign key actions. (check-in: 469a62ca user: dan tags: trunk)
18:25
When compiling with SQLITE_DEBUG, add run-time checks to ensure that no statement aborts unless either there have been no writes or else there is a statement journal. (check-in: ce99c772 user: drh tags: trunk)

2018-05-26
16:00
Store application-defined function names as lower-case to avoid the need for case conversions before calling xFindFunction on virtual tables. Avoid using lookaside to store the destructors for application defined functions, as lookaside should be reserved for transient allocations. (check-in: 777189ce user: drh tags: trunk)

Add a single sentence of documentation about the virtual table scan flags. No changes to code. (check-in: 27b4fa5d user: drh tags: trunk)
2018-05-24
23:51
When doing a one-pass UPDATE or DELETE on virtual tables, close the cursor prior to running VUpdate. This allows one-pass to work on virtual tables that do not allow concurrent reads and writes. Enhance rtree to take advantage of this new capability. (check-in: b816023c user: drh tags: trunk)
22:42
New test case for reading and writing the same rtree concurrently. (check-in: 3ba08e53 user: drh tags: trunk)

17:38
In the OOM testing logic, add the sqlite3FirstFault() routine as a place to set a breakpoint the first time any simulated OOM fault occurs for a single test case. (check-in: b4d80bd2 user: drh tags: trunk)

Initial implementation of the ability to have auxiliary columns in an rtree virtual table that store arbitrary content. It mostly works, but there are some minor issues in OOM corner cases. (check-in: 0c87fec9 user: drh tags: aux-data-in-rtree)
15:35
Enhance the sqlite3_str_new() interface so that it always returns a valid and non-NULL pointer even in an OOM condition. (check-in: ed5b0968 user: drh tags: trunk)

In the CLI, allow comment lines that begin with '#', but only in a context where a dot-command is allowed. In other words, '#' at the beginning of a line in the middle of an SQL statement is just part of the SQL. (check-in: 4ee136d6 user: drh tags: trunk)
2018-05-11
19:11

13:46
Make the internal dynamic string interface available to extensions using the new sqlite3_str object and its associated methods.

10:11
Fix a typo in a comment used for documentation. No code changes. (check-in: b866693e user: drh tags: trunk)

17:27
Improved comments on the cell-overwrite optimization code. (check-in: a4fe966d user: drh tags: trunk)
11:48
On an UPDATE, try to overwrite an existing btree cell with the modified content, if the old and new cell are the same size. Use memcmp() first to avoid dirtying pages that are unchanged. (check-in: 5887d8be user: drh tags: trunk)

Backout change [05fee1a21ea398f1e4d6f1cf3] because it does not take into account the LD_LIBRARY_PATH environment variable used by dl_open(). (check-in: b348d119 user: drh tags: trunk)
2018-05-05
16:50
In an ORDER BY LIMIT, make sure the ORDER BY expression evaluator does not try to reuse values from the result set if the result set has not yet be computed. This fixes a bug in the recent deferred-row loading optimization, check-in [c381f0ea57002a264fd958b28e]. OSSFuzz discovered the problem. (check-in: 5d61e75f user: drh tags: trunk)

22:52
Fix a branch that has become unreachable due to recent enhancements. (check-in: 81ab5e0d user: drh tags: trunk)

19:56
Overhaul of EXPLAIN QUERY PLAN. The output is now in the form of a tree. More details of the query plan are shown, and what is shown is truer to what actually happens. (check-in: ff01bbda user: drh tags: trunk)

Optimizations to the new EQP framework. (Closed-Leaf check-in: 956fef36 user: drh tags: rework-EQP)

14:24
Fix a dangling-else problem that was causing recursive CTEs to malfunction. Begin fixing test cases to work with the new EQP output. (check-in: 82ca44b8 user: drh tags: rework-EQP)

2018-05-01
18:39
The SQLITE_ALLOW_SQLITE_MASTER_INDEX compile-time option allows a CREATE INDEX statement against the sqlite_master table. Once created, the index works, and is usable by legacy instances of SQLite. (check-in: 853f3163 user: drh tags: trunk)
