| 18:39 | The defragmentPage() routine detects corruption in the first-free-slot fields at offset 1 in the header and throws an error, rather than asserting. (check-in: fb125bd3 user: drh tags: trunk) | |
| 17:30 | Add the blobio.c extension module implementing readblob() and writeblob(). Experimental. (check-in: e3fde56d user: drh tags: trunk) | |
|
2019-03-29
| ||
| 17:26 | Change the fts3_tokenizer() function to always return the pointer as a BLOB as long as the first argument is a bound parameter, regardless of the SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER setting. (check-in: 27160df7 user: drh tags: value_frombind) | |

| 13:53 | Show the pointer address for Window objects in the TreeView display. (check-in: 1ae70ad2 user: drh tags: trunk) | |
| 13:35 | More improvements to TreeView output for Window objects: (1) Show when the frame-spec is implied rather than explicit. (2) Move the FILTER clause out from within the OVER clause, making it a sibling of the OVER clause, to match syntax. (check-in: d6a07433 user: drh tags: trunk) | |
| 13:03 | Improved TreeView display of Window objects. Change the Window.eType field to Window.eFrmType to avoid confusion with other "eType" values. (check-in: ec2f207d user: drh tags: trunk) | |

|
2019-03-26
| ||
| 16:21 | Fix harmless compiler warnings. (check-in: a063f7c4 user: drh tags: trunk) | |
| 14:04 | Use the mutex-free PRNG in this branch, since anybody using this branch is probably interested in high concurrency. (check-in: e88fc6d0 user: drh tags: begin-concurrent) | |
| 13:28 | Bring this branch into closer alignment with begin-concurrent. (check-in: 6433d366 user: drh tags: begin-concurrent-pnu) | |

| 12:22 | Merge enhancements from trunk. (check-in: a0e2e902 user: drh tags: wal2) | |
| 12:16 | Merge the latest trunk changes. (check-in: 51e3e835 user: drh tags: begin-concurrent-pnu) | |
| 12:07 | Merge recent enhancements from trunk. (check-in: 774d0d52 user: drh tags: begin-concurrent) | |
| 11:57 | Merge recent trunk enhancements. (check-in: db4e2cc3 user: drh tags: reuse-schema) | |
|
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) | |
|
2019-03-20
| ||
| 20:27 | Experimental change to apply affinity before running CHECK constraints on an INSERT. Note that in the CHECK constraints, REAL affinity really is REAL affinity, and not numeric affinity. This causes failures in some tests that are assuming affinity is applied after CHECK constraints. (Leaf check-in: 9ef69d18 user: drh tags: apply-affinity-first) | |
| 18:22 | In the CLI, give better error messages if something goes wrong with the ".dbinfo" command. (check-in: 3649a77b user: drh 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) | |
|
2019-03-19
| ||
| 20:48 | Merge recent enhancements from trunk. (check-in: 000f4398 user: drh tags: apple-osx) | |
| 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) | |
| 09:57 | Add a LICENSE.md, containing the text of the blessing. (check-in: cbb7e602 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) | |
|
2019-03-14
| ||
| 00:01 | Technical improvements to the documentation for sqlite3_bind_blob() and sqlite3_bind_text(). No changes to code. (check-in: fb60150a user: drh tags: trunk) | |
|
2019-03-13

| 14:07 | Add new test cases in test/fuzzdata8.db (check-in: 97bdc090 user: drh tags: trunk) | |
| 14:02 | Patch makes balance_nonroot() slightly smaller and faster and more robust against corrupt databases. (check-in: 174da3c3 user: drh 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) | |

| 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) | |
|
2019-03-02
| ||
| 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
| ||
| 21:37 | Merge recent changes from trunk. (check-in: f270245a user: drh tags: apple-osx) | |
| 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) | |
