Improve the shell tool ".ar --list --verbose" command. check-in: b64681a6 user: dan tags: sqlar-shell-support
20:38
Show the text of individual statements within a trigger, as they execute, as comments in the output from sqlite3_trace() and sqlite3_trace_v2(). check-in: fe3d2b97 user: drh tags: span-refactor
19:43
Add and use the internal sqlite3DbSpanDup() interface. check-in: a8e1545c user: drh tags: span-refactor
19:27
Merge recent enhancements from trunk. check-in: 76373091 user: drh tags: span-refactor
18:54
Have the shell tool ".ar --list" and ".ar --extract" commands support zip files. Currently the "-zip" switch is required. check-in: a532a0f6 user: dan tags: sqlar-shell-support
18:19
Enhance the Lemon parser generator so that it creates a faster parser at the cost of slightly larger parser tables. Add the ability to measure coverage of the generated state machine when compiling with the -DYYCONVERGE option. In SQLite, add the SQLITE_TESTCTRL_PARSER_COVERAGE test-control to query the new parser coverage feature. check-in: 1b22b42e user: drh tags: trunk
17:36
The previous check-in had an error in the coverage reporting logic. Closed-Leaf check-in: ec9b19eb user: drh tags: lemon-improvements
17:14
Change the coverage measurement logic in the lemon-generated parser so that it only checks for coverage of state/lookahead pairs that are valid syntax. It turns out that some states are unreachable if the lookahead is not valid syntax, because the states are only reachable through a shift following a reduce, and the reduce does not happen if the lookahead is a syntax error. check-in: 9dce4650 user: drh tags: lemon-improvements
16:13
In the lemon-generated parser, do not report the End-of-input character and the wildcard character as missed coverage. check-in: 3fe96487 user: drh tags: lemon-improvements
15:21
In LEMON, fix an off-by-one error that can make the lookahead table one byte too smal. check-in: 93792bc5 user: drh tags: lemon-improvements
2017-12-26
20:39
Add new file ext/misc/zipfile.c, containing a virtual table for read-only access to simple zip archives. check-in: 8e366b99 user: dan tags: sqlar-shell-support
18:32
Change the lemon-parser coverage report format to report all state/lookahead pairs and indicate on each whether it is hit or missed. check-in: 86e30fc2 user: drh tags: lemon-improvements
18:14
Merge bug fixes from trunk. check-in: d76e1206 user: drh tags: lemon-improvements
18:04
Add support for measuring and reporting coverage of the parser state machine using the SQLITE_TESTCTRL_PARSER_COVERAGE test-control. check-in: 1253a872 user: drh tags: lemon-improvements
14:46
Faster and smaller implementation of sqlite3AtoF() based on a suggestion from Cezary H. Noweta. check-in: fd2e0e7a user: drh tags: trunk
14:32
Fix crashes that could occur if SQL NULL values were passed to the built-in FTS5 snippet function. Edit: breaks amalgamation builds. check-in: 6a790b67 user: dan tags: trunk
14:30

2017-12-25
13:43
Fix an assertion fault on a syntax error input caused by check-in [6b2ff26c25bb9da3]. Problem discovered by OSSFuzz. check-in: 90d6e4f1 user: drh tags: trunk
04:15
Enhance LEMON so that it generates the action table in such a way that no range check is needed on the lookahead table to verify that the next input token is valid. This makes the lookahead table slightly larger (about 120 bytes) but helps the parser to run faster. check-in: 7eb0198d user: drh tags: lemon-improvements
00:10
In the LEMON-generated parser, avoid unnecessary tests for the acceptance state. check-in: fdbb35c5 user: drh tags: lemon-improvements
2017-12-24
23:38
In the LEMON-generated parser, rearrange the meanings of integer action codes so that reduce actions occur last. This means that the most common case (reduce actions) can be recognized with a single comparison operation, thus speeding up the main parser loop, slightly. check-in: 7bfe7a36 user: drh tags: lemon-improvements
18:56
Fix a NULL pointer dereference after a syntax error that can occur as a result of check-in [6b2ff26c25bb9da3] yesterday. This problem was discovered by the OSSFuzz. check-in: d49afb8f user: drh tags: trunk
17:06
Improved parser tracing output. check-in: 25be5750 user: drh tags: lemon-improvements
17:01
Grammar changes: the sclp non-terminal should always be followed by a scanpt. check-in: 74a0181f user: drh tags: span-refactor
14:14
Improved parser tracing output. check-in: c4951833 user: drh tags: span-refactor
00:18
Remove the ExprSpan object. Instead, keep track of the test of subphrases in the parse using the "scanpt" non-terminal. check-in: 3eab7bdc user: drh tags: span-refactor

Simplification to the error handling logic in the extension loader. check-in: 07c77314 user: drh tags: trunk
13:55
Improve the error message that comes back when sqlite3_load_extension() fails because the named file exists but is not a valid shared library. check-in: 05fee1a2 user: drh tags: trunk
12:33
Move the generation of output column names earlier in the case of a CREATE TABLE AS. This is a fix for ticket [3b4450072511e62] and a continuation of check-in [ade7ddf1998190b2b63] that fixes cases of ticket [de3403bf5ae5f72ed6] that were missed previously. check-in: 6b2ff26c user: drh tags: trunk
11:51
Add a SELECTTRACE() macro to indicate when column names are assigned to a SELECT statement. This helps with debugging for tickets like [de3403bf5ae5f72e] and [3b4450072511e621]. check-in: 8f194008 user: drh tags: trunk
2017-12-22
19:53
In the sqlite3TreeViewExprList() routine, show the "AS" alias name for each expression in the list, if it exists. check-in: 5efd854f user: drh tags: trunk
00:52
Modify the new sqlite3_vtab_collation() interface so that it takes a pointer to the sqlite3_index_info object passed into xBestIndex rather than an sqlite3 connection pointer, which the xBestIndex method might not have access to. check-in: 5c1fe666 user: drh tags: trunk
2017-12-21
21:41
Fix SQLITE_DBCONFIG_TRIGGER_EQP so that it works even if SQLITE_DEBUG is not defined. check-in: afbbfff7 user: drh tags: trunk
21:02
Add the ".eqp trigger" option to the ".eqp" command in the command-line shell. Implemented using the new SQLITE_DBCONFIG_TRIGGER_EQP control. check-in: 2c51644a user: drh tags: trunk
18:55
Add the ".expert" command to the shell tool's ".help" output. check-in: fc6193af user: dan tags: trunk
18:23
Change the name of SQLITE_DBCONFIG_FULL_EQP to be SQLITE_DBCONFIG_TRIGGER_EQP (which we can do without breaking compatibility because the former name has not yet appeared in an official release) and streamline its implementation. check-in: fffc7685 user: drh tags: trunk
14:46
Add the SQLITE_DBCONFIG_MAX preprocessor macro which will always be equal to the largest SQLITE_DECONFIG value. check-in: 95d41033 user: drh tags: trunk
02:17

17:42
Experimentally add the SQLite expert functionality to the shell tool. Closed-Leaf check-in: 51068dba user: dan tags: expert-in-shell
2017-12-16
20:20
Add an experimental location(X) SQL function that attempt to return the location of the payload within the database for the record that contains column X. location(X) returns NULL if X is not an ordinary table column or if SQLite cannot figure out the location because it is using a covering index. check-in: 51be9558 user: drh tags: location-function
19:36
Add the sqlite3_vtab_collation() function, which allows an xBestIndex callback to determine the collation sequence that SQLite will use for a comparison. And the SQLITE_DBCONFIG_FULL_EQP configuration option, which enhances the output of "EXPLAIN QUERY PLAN" so that it includes statements run by triggers. And the code for the sqlite3_expert extension and command line application. check-in: 4c782c95 user: dan tags: trunk

Avoid adding INTEGER PRIMARY KEY columns to candidate indexes. check-in: 4577fea5 user: dan tags: schemalint
