2019-03-25
| ||
| 22:05 | Fix an obsolete comment in the CLI. No code changes. check-in: fade103c user: drh tags: trunk | |
| 21:56 | In the CLI, code the "sqlite_parameters" name directly rather than using a macro, for clarity of presentation for users who are reading the code for the purpose of seeing how the CLI implements parameter binding. check-in: e775ef00 user: drh tags: trunk | |
| 21:55 | Remove a test from the index build logic which is no longer needed and is in fact unreachable. check-in: 9b20ee10 user: drh tags: trunk | |
| 21:35 | Change the name of the parameter table in the CLI to "sqlite_parameters". Doing so involves adding SQLITE_DBCONFIG_WRITABLE_SCHEMA and allowing the creation of tables whose names begin with "sqlite_" and that are indexed while writable_schema is on. check-in: 24ef3844 user: drh tags: trunk | |
| 19:50 | Earlier detection of corruption while added to the freelist. check-in: 8c80b004 user: drh tags: trunk | |
| 18:44 | Fix a faulty assert() statement in balance_nonroot() - the assert() should use get2byteNotZero() instead of get2byte() for the corner case where the number cells is zero on a 65536-byte page. check-in: bcbe7d96 user: drh tags: trunk | |
| 15:09 | Improvements to the help text in the CLI. check-in: 919fec91 user: drh tags: trunk | |
| 15:06 | Fix the writefile() SQL function implemented by ext/misc/fileio.c such that any directories created have standard umask permissions, not permissions of the file that is to be written. check-in: f11c8959 user: drh tags: trunk | |
| 14:24 | For the ".archive --update" command in the CLI, only update files if their mtime or mode has changed. To force an update, use the new --insert instead. check-in: 191a023a user: drh tags: trunk | |
|
2019-03-22
| ||
| 13:53 | We learn that readdir_r() is deprecated in favor of plain old readdir(), which is now suppose to be threadsafe using thread-local storage. So remove the use of readdir_r() from the test code. (SQLite itself never calls readdir() or readdir_r()). check-in: 7a0a26ed user: drh tags: trunk | |
| 11:38 | Add the --limit N option to dbfuzz2. Set the default callback limit to 250K. check-in: b99f8512 user: drh tags: trunk | |

| 18:22 | In the CLI, give better error messages if something goes wrong with the ".dbinfo" command. check-in: 3649a77b user: drh tags: trunk | |
| 16:58 | Fix a potential dangling pointer deference in an ALTER TABLE run on a schema that contains constructs of the form "PRIMARY KEY(column COLLATE collation)". check-in: b9e2393c user: dan tags: trunk | |
| 12:08 | Fix harmless compiler warnings from MSVC. check-in: f0f02d46 user: drh tags: trunk | |
| 11:16 | Enhance the rtreenode() function of rtree (used for testing) so that it uses the newer sqlite3_str object for better performance and improved error reporting. Test cases added to TH3. check-in: 90acdbfc user: drh tags: trunk | |
| 05:45 | Fix various harmless compiler warnings seen with MSVC. Closed-Leaf check-in: 1c0fe5b5 user: mistachkin tags: noWarnings | |
|
2019-03-19

| 20:42 | Enhance the VACUUM INTO command so that it works on read-only databases. check-in: 55be6d0a user: drh tags: trunk | |
| 20:13 | Fix a compiler warning in FTS5. check-in: d5acf3af user: drh tags: trunk | |
| 15:36 | When computing the amount of scratch memory needed during a rebalance operation, assume the worst case for the number of cells per page, rather than relying on the BtPage.nCell value, which might be incorrect for a corrupt database. check-in: a420ebd0 user: drh tags: trunk | |
| 11:35 | Tweak the tool/cg_anno.tcl script so that it can run on systems without /usr/bin/tclsh. check-in: a026189a user: dan tags: trunk | |
| 09:57 | Add a LICENSE.md, containing the text of the blessing. check-in: cbb7e602 user: drh tags: trunk | |
|

|
2019-03-17
| ||
| 23:59 | New hyperlink on the README.md file. check-in: cc5ab967 user: drh tags: trunk | |
| 23:44 | Update the README.md file at the top level to talk about how to deal with version names and how to verify the code in Git mirrors. check-in: e8c87a0a user: drh tags: trunk | |
|
2019-03-15
| ||
| 19:08 | Back out the change to support Fuchsia, since it turns out fuchsia does not like dot-file locks. check-in: 1d801a3b user: drh tags: trunk | |
| 18:57 | Remove a debugging printf() left in test/sessionfuzz.c. check-in: 73c4abc9 user: dan tags: trunk | |

| 10:29 | Detect zero-length free slots on btree pages and report that as corruption. check-in: c4f0568f user: drh tags: trunk | |
|
2019-03-12
| ||
| 09:49 | Fix a crash that could occur if the RHS of an IN expression is a correlated sub-query that refers to the outer query from within a window frame definition only. check-in: 0524aaaf user: dan tags: trunk | |
|
2019-03-08
| ||
| 20:26 | Fix a harmless bug in the Makefile. check-in: 62ac9cb0 user: drh tags: trunk | |

| 13:27 | Fix another segfault in fts3 that could occur with corrupt records. check-in: fcc24edd user: dan tags: trunk | |
| 01:52 | Detect an attempt to drop a btree that is not within the bounds of the database file and abort early with an SQLITE_CORRUPT error, to avoid problems later on in the process. check-in: 235a9698 user: drh tags: trunk | |
|
2019-03-06
| ||
| 14:53 | Add the sqlite3_stmt_isexplain() interface. check-in: ee642d3e user: drh tags: trunk | |
| 14:08 | Add an "|| CORRUPT_DB" term to an assert() that might be false if the database is corrupt. Also add a branch to have sqlite3PagerMovepage() return SQLITE_CORRUPT in that case. check-in: b0d5cf40 user: drh tags: trunk | |
|
2019-03-05
| ||
| 23:49 | Fix a potential 32-bit integer overflow in the "showdb" utility program when it is trying to interpret a corrupt database file. check-in: 3803e750 user: drh tags: trunk | |
| 16:53 | Add a script to tool/ that will extract the sqlite3.h header file from an sqlite3.c amalgamation. check-in: 38d2e510 user: drh tags: trunk | |
| 14:47 | New dbfuzz2 test cases added to test/fuzzdata7.db check-in: 25975e1f user: drh tags: trunk | |
| 14:39 | If the initial byte of a record is a large value, then always used the generalized record comparison routine sqlite3VdbeRecordCompare() rather than one of the specialized versions that are optimized for shorter records. check-in: c1ac0070 user: drh tags: trunk | |
|
2019-03-04
| ||
| 07:15 | Fix a problem preventing compilation with SQLITE_OMIT_UTF16. check-in: 906d1fd8 user: dan tags: trunk | |
|
2019-03-02
| ||
| 20:09 | Improved comments on the fossildelta.c extension. check-in: d7d23f04 user: drh tags: trunk | |

| 12:17 | Remove a redundant parameter extraction call from the percentile.c extension. check-in: d49c32e6 user: drh tags: trunk | |
|
2019-03-01
| ||
| 21:33 | The fts3_tokenizer() function returns NULL if the SQLITE_DBCONFIG_ENABLE_FTS_TOKENIZER setting is disabled, which is is by default. check-in: f5732f4c user: drh tags: trunk | |
| 21:12 | Fix a minor comment typo. No code changes. check-in: 9a0a93c8 user: drh tags: trunk | |
| 18:07 | In a query that uses a partial index, the expression that is the WHERE clause of the partial index must always be true. Use this fact to avoid evaluating identical terms in the WHERE clause of the query. check-in: 9b287962 user: drh tags: trunk | |
|
2019-02-28
| ||
| 20:10 | Add the ".parameter" command to the CLI. check-in: 1f9fa585 user: drh tags: trunk | |
| 17:29 | Add the new "bind_fallback" method to the "sqlite3" object in the TCL interface. check-in: c7f70b6d user: drh tags: trunk | |
| 14:09 | New test case loaded into test/fuzzdata8.db. check-in: 00ae0c6c user: drh tags: trunk | |
| 13:41 | Avoid an assert() failure and an undefined left-shift operation in the fts3 snippet() function that could occur if the database was corrupt. check-in: d5250db6 user: dan tags: trunk | |
| 13:21 | Add an "|| CORRUPT_DB" term to an assert() statement in the btree defragmenter. check-in: 6bfd8655 user: drh tags: trunk | |
|
2019-02-27
| ||
| 23:05 | Enable the LIKE optimization when the ESCAPE keyword is present and the PRAGMA case_sensitive_like pragma is ON. check-in: 6ae4b8c5 user: drh tags: trunk | |
| 19:59 | Fix the readfile() UDF so that it returns an empty BLOB, not an OOM error, when reading an empty file. check-in: 0edad533 user: drh tags: trunk | |
| 16:38 | Add the "-returntype" option to the "db function" Tcl method. check-in: 789a492b user: dan tags: trunk | |

|
2019-02-26
| ||

| 16:17 | Use unsigned integers to count the number of pages in a freelist during an integrity_check, to avoid any possibility of a signed integer overflow. check-in: 05b87e07 user: drh tags: trunk | |
| 16:11 | Fix a harmless compiler warning that only comes up during debug builds. check-in: 848869ce user: drh tags: trunk | |

|
2019-02-25
| ||
| 18:43 | Enhance the command-line shell to accept bound parameters, using the TEMP table named "$Parameters" to look up the values for bound parameters. check-in: 7c941ce5 user: drh tags: trunk | |
| 14:52 | Update comments on the fossildelta extension. No changes to code. check-in: 9da4fb59 user: drh tags: trunk | |
| 14:16 | Fix a typo in the documentation for sqlite3_total_changes(). check-in: 8474c156 user: drh tags: trunk | |
|
2019-02-23
| ||
| 20:48 | Fix a couple of assert() statements in fts3 that can be false if the database is corrupt. check-in: 84162af5 user: dan tags: trunk | |
| 00:21 | Check-in [fa792714ae62fa98] is incorrect. Add a test case to refute it and also a fix to make it right. Then add an alternative fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. check-in: d3915230 user: drh tags: trunk | |
| 00:08 | Remove a testcase() macro which is now unreachable due to the contraction of the use of IN_INDEX_ROWID. Closed-Leaf check-in: 90c5a17c user: drh tags: tkt-df46dfb631 | |
|
2019-02-22
| ||
| 23:29 | Make all ephemeral tables built to hold the RHS of an IN operator be index-btrees, never table-btrees, regardless of whether or not they are used as IN_INDEX_LOOP or IN_INDEX_MEMBERSHIP. That way, the same ephmerial table can be reused for both cases. check-in: c2d50df8 user: drh tags: tkt-df46dfb631 | |
| 21:33 | Check-in [fa792714ae62fa980] is not a valid fix for ticket [df46dfb631f75694], as the new test case in this check-in demonstrates. The fix here causes test cases for the [df46dfb631f75694] bug to fail again, so this check-in is on a branch. A new fix is needed for [df46dfb631f75694]. check-in: 0d456456 user: drh tags: tkt-df46dfb631 | |
| 19:24 | Internally, remove all references to a Window object that belongs to an expression in an ORDER BY clause if that expression is converted to an alias of a result-set expression. Fix for [4feb3159c6]. check-in: 579b66ea user: dan tags: trunk | |
| 16:18 | In sqlite3NestedParse() be sure to detect all SQLITE_NOMEM and SQLITE_TOOBIG errors and to distinguish between them. check-in: 73056b31 user: drh tags: trunk | |
| 15:42 | Modify sqlite3_str_finish() and sqlite3VMPrintf() so that they always return NULL on any OOM or SQLITE_LIMIT_LENGTH error. check-in: e7144ffd user: drh tags: trunk | |
|
2019-02-21
| ||
| 16:41 | Detect oversized strings in the OP_String opcode even if the P4 argument is originally UTF8 and has to be converted to UTF16 to match the database file and that conversion causes the string to become shorter and cross below SQLITE_LIMIT_LENGTH threshold. This might fix an OSSFuzz problem that we have been so far unable to reproduce. check-in: c13d5639 user: drh tags: trunk | |
|
2019-02-20
| ||
| 19:20 | Changes to the unix VFS that allegedly enable it to build of Fuchsia. We have no way of testing this. check-in: be21a641 user: drh tags: trunk | |
| 19:06 | Disable unix-specific features of dbfuzz2 when compiling on windows. check-in: af84774d user: drh tags: trunk | |
| 18:13 | Avoid the use of function pointers in columnName(), as function pointers appear to be a source of consternation to LLVM. check-in: c48f6f39 user: drh tags: trunk | |
| 13:55 | Progress handler improvements: (1) Invoke the callback after OP_Program opcodes (2) Invoke the callback multiple times in a row to catch up after a long run of no progress checks. check-in: 0c5db18d user: drh tags: trunk | |
| 12:52 | When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. This is a better fix for ticket [df46dfb631f75694] than the previous fix that is now on a branch as it preserves the full optimization of check-in [e130319317e76119]. check-in: fa792714 user: drh tags: trunk | |
|
2019-02-19
| ||
| 20:29 | Enhance the xBestIndex method on delta_parse() to return SQLITE_CONSTRAINT if no delta argument is supplied. check-in: f16d127c user: drh tags: trunk | |
| 20:19 | Add the delta_parse(DELTA) table-valued function to the fossildelta extension. check-in: d91fcc26 user: drh tags: trunk | |
| 18:39 | Add the fossildelta.c extension in ext/misc with implementations of the Fossil delta functions. check-in: b80cafa6 user: drh tags: trunk | |
| 17:45 | Fix a potential memory leak in RBU if the rbu_fossil_delta() SQL function is misused. Misuse never happens in a working RBU system, so this is not a particularly important fix. check-in: 12517d1b user: drh tags: trunk | |
| 16:42 | Fix an assert() that might not be true if the database file is corrupt. check-in: f2d400db user: drh tags: trunk | |
| 13:51 | New assert() to verify the TF_HasprimaryKey flag. check-in: 0abace8a user: drh tags: trunk | |
| 13:08 | Always use the symbolic name SQLITE_IDXTYPE_PRIMARYKEY rather than a hard-coded magic number 2. check-in: 55d43adc user: drh tags: trunk | |
|
2019-02-18
| ||
| 12:16 | Fix an assert() that might not be true if the %_segdir table of FTS3 contains corrupt entries. check-in: a6509ca3 user: drh tags: trunk | |
|
2019-02-16
| ||
| 22:45 | Fix an assert() that might be false for a corrupt database. check-in: 0cfb8887 user: drh tags: trunk | |
|
2019-02-14
| ||
| 15:27 | Improved oversized cell detection when updating ptrmap pages in balance_nonroot(). check-in: aa61435a user: drh tags: trunk | |
|
2019-02-12
| ||
| 22:58 | Ensure that the nProgressLimit variable is always initialized in sqlite3VdbeExec(), even if the routine jumps to its exit processing early. check-in: 167b91df user: drh tags: trunk | |
| 21:04 | Enhancement the progress callback mechanism so that the progress callback is always invoked at least once at the end of a prepared statement if the opcode count has been exceeded. This makes the progress callback more effective at limiting run times. This check-in also includes and unrelated performance enhancement to OP_Column. check-in: 68cce272 user: drh tags: trunk | |
