Fix problem causing free-list corruption when merging free-lists for two concurrent transactions that have both used page X as an in-memory free-list trunk page, where X lies past the end of the initial database images. (check-in: dc0fc2aa user: dan tags: begin-concurrent-pnu)
2018-01-02
19:57
Fix a spurious SQLITE_CORRUPT error that could occur within a COMMIT of a concurrent transaction. (check-in: 50c8952c user: dan tags: begin-concurrent-pnu)
2018-01-01
20:11
Minor simplification to the ".schema" logic in the command-line shell. (check-in: add45c47 user: drh tags: trunk)

Experiments with the regexp.c extension, trying to get it to report the exact substring that matches the RE. (Leaf check-in: 3d6fba62 user: drh tags: regexp-span)
2017-12-30
18:32
Have zipfile support DELETE commands. (check-in: 01d4e866 user: dan tags: sqlar-shell-support)
14:26
Rearrange things a bit so that writing to a zipfile does not invert the order of objects it contains. (check-in: f69e8194 user: dan tags: sqlar-shell-support)
2017-12-29
20:19
Update ext/misc/zipfile.c to support creating and adding entries to existing zip archives. (check-in: 2dec2dec user: dan tags: sqlar-shell-support)
17:21
Add support for the sqlite_unsupported_offset() SQL function if and only if compiled using -DSQLITE_ENABLE_OFFSET_SQL_FUNC. Use that definition when compiling the command-line shell. (check-in: 4f1f1f52 user: drh tags: trunk)
16:37
Stricter test cases. (Closed-Leaf check-in: 9406c0a6 user: drh tags: location-function)
15:19
Fix a typo in the MSVC makefile. (check-in: 89e5720a user: drh tags: location-function)
15:04
Change the function name to sqlite_unsupported_offset(X). Only enable the function if compiled with -DSQLITE_ENABLE_OFFSET_SQL_FUNC. The makefiles add that definition to shell builds. (check-in: 7a7f826e user: drh tags: location-function)
14:33
Enhance location(X) so that it works with indexes and WITHOUT ROWID tables. The function might return an offset to the main table or to an index, depending on whether the column X would be loaded from the main table or from the index. (check-in: dd94d6a8 user: drh tags: location-function)
13:35
Merge recent enhancements from trunk. (check-in: 6251e438 user: drh tags: location-function)
12:50

2017-12-27
22:09
The output of sqlite3_trace() now shows each command of a trigger as it is evaluated. This feature involved major changes to the parser, such as removing the ExprSpan object and replacing it with a new mechanism for capturing the original SQL text of phrases in the input SQL. (check-in: 0fdf97ef user: drh tags: trunk)
21:30
Omit all sqlite3_trace() output from the triggers associated with foreign key constraints. (Closed-Leaf check-in: fda08e3d user: drh tags: span-refactor)
21:13
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
Add options to speedtest1.c and speed-check.sh for testing performance of floating-point computatations. (check-in: ebfea872 user: dan tags: trunk)
14:12
Add options to speedtest1.c and speed-check.sh for testing performance of floating-point computatations. (Closed-Leaf check-in: b3c61051 user: drh tags: mistake)
14:11
Fix crashes that could occur if SQL NULL values were passed to the built-in FTS5 snippet function. Edit: breaks amalgamation builds. (check-in: 553a3ad3 user: dan tags: mistake)
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)
2017-12-23
18:40
Merge recent enhancements from trunk. (check-in: edceaccd user: drh tags: appendvfs)
18:34
Merge enhancements from trunk. (check-in: 150f07fe user: drh tags: sqlar-shell-support)

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)

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)
19:16
Merge latest trunk changes into this branch. (Closed-Leaf check-in: d5b597b5 user: dan tags: schemalint)
19:11
Do not use the compress() and uncompress() functions in ext/misc/compress.c - they are not quite compatible with the spec. Instead use new functions in ext/misc/sqlar.c. (check-in: 7652b3c2 user: dan tags: sqlar-shell-support)
04:37
Add unnecessary initializations to some local variables in the rtree module to suppress false-positive compiler warnings coming out of MSVC. (check-in: 64487d65 user: drh tags: trunk)
2017-12-15
20:21
Enhance the "swarmvtab" extension. See header comments in ext/misc/unionvtab.c for details. (check-in: 01c17365 user: dan tags: trunk)

20:02
New result code SQLITE_READONLY_DIRECTORY is returned when an attempt is made to write on a database file that is in a read-only directory and hence the journal file could not be created. This situation formerly returned SQLITE_CANTOPEN, which less helpful. (check-in: 3ec73c38 user: drh tags: trunk)
18:01
Correctly invalidate a column cache line when it is overwritten with NULL. Fix for ticket [123c9ba32130a6c9d432]. (check-in: 65754dc3 user: drh tags: trunk)
15:32
Change some LSM code internal typenames from "Blob" and "Pgno" to "LsmBlob" and "LsmPgno". This allows the LSM code to be compiled as a single unit with sqlite3.c. (check-in: 30bf38d5 user: dan tags: trunk)
14:22
Add script to amalgamate all LSM files into "lsm1.c". (check-in: e32b69d7 user: dan tags: trunk)
