23:41 | Fix invalid use of unprotected sqlite3_value objects in the sqldiff utility, when using the --changeset option. (check-in: a8d65214 user: drh tags: trunk) | |
20:04 | When a table is renamed using "ALTER TABLE RENAME TO", update any REFERENCES clauses that refer to the table, unless "PRAGMA legacy_alter_table" is true and "PRAGMA foreign_keys" is set to false (i.e. so that when "PRAGMA legacy_alter_table" is set behaviour is still compatible with versions 3.24 and earlier). (check-in: ae9638e9 user: dan tags: trunk) | |
14:17 | Fix for ticket [787fa716be3a7f650cac] (check-in: 531eca61 user: drh tags: trunk) | |

2018-11-05
| ||
19:37 | Add the SQLITE_DBCONFIG_DEFENSIVE flag. (check-in: 11d98414 user: drh tags: trunk) | |
16:38 | Eponymous virtual tables appear to exist in all schemas. This is an alternative and improved fix to the eponymous virtual table in trigger problem that was previously addressed by checkin [1fa74930ab56171e]. (check-in: b8d35c4a user: drh tags: trunk) | |
07:53 | Disable the IS NOT NULL optimization when the IS NOT NULL operator is part of the ON clause of a LEFT JOIN. Fix for ticket [65eb38f6e46de8c75e188a17ec]. (check-in: af39661e user: drh tags: trunk) | |
2018-11-03

13:11 | Fix a assert() in the query planner that can arise when doing row-value operations on a PRIMARY KEY that contains duplicate columns. Ticket [1a84668dcfdebaf12415d]. (check-in: dcb8c735 user: drh tags: trunk) | |
2018-11-02
| ||
17:38 | Enhance triggers so that they can use table-valued-functions that exist in schemas outside of the schema in which the trigger is defined. (check-in: 1fa74930 user: drh tags: trunk) | |
2018-10-31
| ||
20:52 | Deploy the sqlite3Strlen30NN() function (argument guaranteed to be non-NULL) for a small performance improvement. (check-in: 4a6ad519 user: drh tags: trunk) | |
19:01 | Add support for the SQLITE_PREPARE_NORMALIZED flag and the sqlite3_normalized_sql() when compiling with SQLITE_ENABLE_NORMALIZE. Also remove unnecessary whitespace from Makefiles. (check-in: 790ea39a user: drh tags: trunk) | |
18:24 | Tweaks to the test_intarray documentation and tests. (check-in: 7107f0da user: drh tags: trunk) | |
01:12 | Merge fuzz test cases computed by dbfuzz2. (check-in: e0d30c18 user: drh tags: trunk) | |
01:04 | Improved corrupt database detection in the relocatePage() routine of the b-tree module. (check-in: d5787333 user: drh tags: trunk) | |
2018-10-30
| ||
23:45 | Add new fuzzer cases generated by dbfuzz2. (Closed-Leaf check-in: 79fdad8b user: drh tags: dbfuzz2-cases) | |
19:14 | Update comments in sqlite3session.c to describe the format of "rebase blobs", as well as changesets and patchsets. (check-in: bf93f7b5 user: dan tags: trunk) | |
16:25 | Split the SQLITE_WriteSchema flag in two flags, WriteSchema and SQLITE_NoSchemaError. Set only WriteSchema on a VACUUM to avoid problems when trying to vacuum a corrupt database. With this change, the size of the flags field on sqlite3 must grow from 32 to 64 bytes. (check-in: 4f987810 user: drh tags: trunk) | |
15:31 | Modify the CLI so that the --deserialize option is only available if it is compiled with SQLITE_ENABLE_DESERIALIZE. DESERIALIZE is now off by default for the main.mk makefile, but on for Makefile.in and Makefile.msc. (check-in: 90b2a684 user: drh tags: trunk) | |
15:20 | Improvements to the -fsanitize=fuzzer based database file fuzzer. (Cherrypick from the rubust-against-damaged-db branch.) (check-in: 3cc01a0e user: drh tags: trunk) | |

13:19 | Enable sqlite3_deserialize() in the CLI. The --deserialize option associated with opening a new database cause the database file to be read into memory and accessed using the sqlite3_deserialize() API. This simplifies running tests on a database without risk of modifying the file on disk. (check-in: 5e0129ee user: drh tags: trunk) | |
00:06 | Improvements to the -fsanitize=fuzzer based database file fuzzer. (Closed-Leaf check-in: 585c94db user: drh tags: robust-against-damaged-db) | |

00:47 | Initial code for a fuzzing tool on database file that works with the -fsanitize=fuzzer option of clang. (check-in: 90d12094 user: drh tags: trunk) | |
2018-10-26
| ||
17:05 | Add the sqlite3session_config() interface. For configuring global parameters belonging to the sessions module. (check-in: 1e69f3ff user: dan tags: trunk) | |
15:36 | Prevent an == constraint specified using the table-valued-function argument syntax from being used to optimize any scan not related to the virtual table for which it was specified as an argument. (check-in: 4d46685f user: dan tags: trunk) | |
2018-10-25
| ||
14:15 | In the WHERE-constraint propagation optimization, if there are duplicate constraint, make sure only one of them propagates. Proposed fix for ticket [cf5ed20fc8621b165]. (check-in: 5d5b596f user: drh tags: trunk) | |
2018-10-24

2018-10-23
| ||
13:48 | Fix a problem with using window functions in compound (UNION, INTERSECT etc.) queries. (check-in: 059ff53a user: dan tags: trunk) | |
2018-10-20
| ||
13:48 | Add the sqlite3changeset_start_v2() - a new version of _start() that accepts a flags parameter - and a streaming equivalent to the sessions module. Also add the SQLITE_CHANGESETSTART_INVERT flag, used with start_v2() to invert a changeset while iterating through it. (check-in: cbedcb9a user: dan tags: trunk) | |
2018-10-18
| ||
15:17 | Take steps to avoid a potential integer overflow in sessionBufferGrow(). (check-in: f7affa2e user: dan tags: trunk) | |
14:59 | Add the SQLITE_CHANGESETAPPLY_INVERT flag to sessions. For inverting and applying a changeset in a single step. (check-in: d4b6406e user: dan tags: trunk) | |
2018-10-12
| ||
15:01 | Test case modifications to support SEE. (check-in: 02b6f8f2 user: drh tags: trunk) | |
2018-10-11
| ||

18:28 | Add the textkey and textrekey pragmas. (check-in: f829099d user: drh tags: apple-osx) | |
16:53 | Fix harmless compiler warnings in the CLI. (check-in: 1916d291 user: drh tags: trunk) | |
16:38 | Always reset the pager before changing the codec. (check-in: 0bf0fd24 user: drh tags: trunk) | |
13:51 | On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. (check-in: 90cf32cd user: drh tags: trunk) | |
10:37 | In the CLI, fix a file descriptor leak following OOM and a missing va_end() call. (check-in: ec36d15a user: drh tags: trunk) | |

2018-10-10
| ||
18:56 | In the CLI, allow the SQLITE_HISTORY environment variable, if it exists, to specify an alternative file in which to store the shell edit history. (check-in: 696e82f7 user: drh tags: trunk) | |
2018-10-08
| ||
20:04 | Fix an issue with the new memstat.c extension. (check-in: ce6e80b1 user: drh tags: trunk) | |
18:55 | Replace the new geopoly_reverse() function with geopoly_ccw(). The geopoly_ccw() function only reverses the vertex order if doing so is necessary to get the correct right-hand winding rule on the polygon. (check-in: 07506694 user: drh tags: trunk) | |
12:58 | Add the geopoly_reverse() function to the GeoPoly extension. (check-in: 690dd18a user: drh tags: trunk) | |

2018-10-05
| ||
15:10 | Changes to geopoly to silience false-positive warnings coming out of clang. (check-in: 11d9015f user: drh tags: trunk) | |
2018-10-03
| ||
18:05 | Add an ALWAYS on an unreachable branch in the ALTER TABLE logic. (check-in: ebcd4523 user: drh tags: trunk) | |
11:13 | Change a type in shell.c.in from "int" to "sqlite3_int64" in order to avoid a compiler warning and possible integer overflow. (check-in: bf0a6634 user: dan tags: trunk) | |
2018-10-02
| ||
20:16 | Add an additional assert() verifying mutex invariants on the unixShmSystemLock() routine in the unix VFS. (check-in: cb151106 user: drh tags: trunk) | |
19:58 | Additional field name changes and commit fixes associated with shared-memory locking in the unix VFS, to improve maintainability. No logic changes. (check-in: 9280774a user: drh tags: trunk) | |
19:36 | Fix comments and refactor some names associated with shared-memory locking in the Unix VFS. No logical changes. (check-in: 3e9f1635 user: drh tags: trunk) | |
2018-10-01
| ||
21:41 | Add the "PRAGMA table_xinfo" command that works like table_info but also shows hidden columns in virtual tables and adds the "hidden" boolean column. (check-in: defa0515 user: drh tags: trunk) | |
21:36 | Test case for PRAGMA table_xinfo. (Closed-Leaf check-in: 7694b9bc user: drh tags: pragma-table-vinfo) | |
21:26 | Change the name of the pragma to PRAGMA table_xinfo. Improve the mkpragmatab.tcl script to reuse column names where appropriate. (check-in: 2fdd0689 user: drh tags: pragma-table-vinfo) | |
18:28 | Add the extra "hidden" column to the end of the PRAGMA table_vinfo output. (check-in: cf1b7613 user: drh tags: pragma-table-vinfo) | |
17:33 | Speed up xAccess() calls made on an RBU VFS when there are lots of open connections. (check-in: 310b4b65 user: dan tags: trunk) | |
17:15 | Bring the PRAGMA table_vinfo statement up to date with trunk. (check-in: 6f606f99 user: drh tags: pragma-table-vinfo) | |
13:54 | Fix a potential crash that can occur while reading an index from a corrupt database file. The corruption is a record-header-size that is larger than 0x7fffffff. Problem detected by OSSFuzz against GDAL and reported to us (with a suggested fix) by Even Rouault. The test case is in TH3. (check-in: 8ac2cdda user: drh tags: trunk) | |
07:04 | Fix a problem with ALTER TABLE commands when the schema features an INSTEAD of trigger that uses NEW.* or OLD.*. (check-in: c52f457e user: dan tags: trunk) | |
2018-09-29
| ||
19:38 | Add the PRAGMA table_vinfo command (with an extra "v" before "info") that works like PRAGMA table_info (without the "v") except that it also shows hidden columns on virtual tables. (check-in: 8bcd1a59 user: drh tags: pragma-table-vinfo) | |
2018-09-28

13:18 | Make most geopoly functions pure. (check-in: 944e167a user: drh tags: trunk) | |
00:16 | Rig geopoly to use sqlite3AtoF() if it is available, as that routine is much faster than atof(). (check-in: 470c6c07 user: drh tags: trunk) | |
2018-09-27
| ||
23:57 | Small performance optimization in the JSON parser of Geopoly. (check-in: fb520e71 user: drh tags: trunk) | |
20:37 | Enhance the GeoPOLY extension so that it always stores its polygons in the binary format, which is faster and more compact. (check-in: dc35f7b1 user: drh tags: trunk) | |
20:20 | Ensure that the OP_VColumn opcode does set sqlite3_vtab_nochange() unless the OPFLAG_NOCHNG bit is set in P5. Fix for ticket [69d642332d25aa3b7315a6d385] (check-in: 322ab1fc user: drh tags: trunk) | |

16:57 | Enhancements to sqlite_memstat: (1) Add an extra "schema" column to show the schema name for ZIPVFS stats. (2) Only show ZIPVFS stats to schema that use ZIPVFS (3) Put a NULL in unused columns of the output. (Closed-Leaf check-in: 9351135b user: drh tags: memstat-vtab) | |
15:45 | Add initial ZIPVFS support for the "main" database to the sqlite_memstat virtual table. (check-in: 9cd27350 user: drh tags: memstat-vtab) | |
15:21 | Initial prototype of a eponymous virtual table that accesses sqlite3_status64() and sqlite3_db_status(). (check-in: 0b44e1f6 user: drh tags: memstat-vtab) | |
12:14 | Disallow the use of window functions in the recursive part of a recursive CTE. Fix for ticket [e8275b415a2f03bee]. (check-in: 7fc29944 user: dan tags: trunk) | |
00:04 | Minor simplification: In OP_ParseSchema, read the p1 register once. (check-in: bd250533 user: mistachkin tags: trunk) | |
2018-09-26
| ||
18:02 | Further improvements to the ".help" command in the CLI. (check-in: edc3d18e user: drh tags: trunk) | |
16:53 | Begin revamping the ".help" command in the command-line shell so that it can accept an argument and will do a search for commands that match that argument. (check-in: 209afb8d user: drh tags: trunk) | |
16:05 | Tweak spellfix.c so that if SQLITE_SPELLFIX_5BYTE_MAPPINGS is defined at compile time the Transliteration structure has space for 5 byte (instead of 4 byte) mappings. (check-in: cbaf5b6c user: dan tags: trunk) | |
03:43 | Fix typos in the header comment for the sha1 and sha3 hash extensions in the ext/misc folder. (check-in: 4ed9d83a user: drh tags: trunk) | |
2018-09-25
| ||
13:51 | Fix a problem in releasetest.tcl causing configuration "Fast-One" to fail. (check-in: 42e04fef user: dan tags: trunk) | |
2018-09-24
| ||
15:39 | Slightly smaller and faster alternative to [507d892c3a40a0bacbd47] that fixes a problem with views that use window function as part of complex expressions. (check-in: d7c816ae user: drh tags: trunk) | |
14:51 | Fix a problem with views that use window functions as part of complex expressions. (check-in: 507d892c user: dan tags: trunk) | |
14:10 | Allow a writable virtual table to have a schema with an INTEGER PRIMARY KEY and WITHOUT ROWID. This fixes ticket [f25d5ceebe1d710ff61a571e395356869d8272ef]. Test case in TH3. (check-in: 5a38d928 user: drh tags: trunk) | |
12:37 | Use compile-time options SQLITE_QUERY_PLANNER_LIMIT and SQLITE_QUERY_PLANNER_LIMIT_INCR to control the value for WhereLoopBuilder.iPlanLimit, rather than embedding magic numbers in the code. (check-in: 903e5018 user: drh tags: trunk) | |
10:47 | Increase the initial value of WhereLoopBuilder.iPlanLimit to 20K. Issue a warning if the iPlanLimit reaches zero. (check-in: 3dd35f51 user: drh tags: trunk) | |
