2025-05-06
| ||
| 23:01 | Merge the latest trunk enhancements into the reuse-schema branch. (Leaf check-in: f98aa940b4 user: drh tags: reuse-schema) | |
| 21:45 | Merge the latest trunk enhancements into the bedrock branch. (Leaf check-in: 9d6517e7cc user: drh tags: bedrock) | |
| 21:38 | Merge the latest trunk changes into the wal2 branch. (Leaf check-in: b17f5beab8 user: drh tags: wal2) | |
| 21:26 | Merge all the latest trunk enhancements into the begin-concurrent branch. (Leaf check-in: 55a51ba58f user: drh tags: begin-concurrent) | |
| 18:04 | Fix a bug in the NOT NULL/IS NULL optimization that can cause invalid data to be used for a column if that column has a CHECK constraint that includes the NOT NULL or IS NULL operator. (Leaf check-in: 9d1f01aac9 user: drh tags: branch-3.49) | |
| 17:56 | Add test cases for the NOT NULL/IS NULL optimization in CHECK constraints fix. (Leaf check-in: 6eb2939a60 user: dan tags: trunk) | |
| 17:53 | Fix a bug in the NOT NULL/IS NULL optimization of check-in [cb94350185f555c3] that can cause invalid data to be used for a column if that column has a CHECK constraint that includes the NOT NULL or IS NULL operator. Problem discovered by the Chromium fuzzer. Never seen in the wild, as far as anybody knows. (check-in: 2adaee9aa9 user: drh tags: trunk) | |
| 16:28 | Fix the sqlite3VdbeTypeofColumn() function so that it works correctly even when SQLITE_DEBUG is defined. (check-in: 1d5021533e user: drh tags: trunk) | |
| 15:39 | Fix console-I/O on Windows for DEBUG=3 builds. Broken by [925e97e6f4238f02]. (check-in: ccef4f7058 user: drh tags: trunk) | |

| 23:44 | Account for Tcl 8.x's lack of Tcl_BounceRefCount(). (Leaf check-in: 46b0bf5603 user: stephan tags: tcl-cw) | |
| 22:56 | Part 2 of 2(?) of adding the -asdict flag to the db eval command of the Tcl interface. This needs a critical review from seasoned Tcl C API users before merging can be considered (noting that it's not planned for inclusion until 3.51). (check-in: 5368647a1f user: stephan tags: tcl-cw) | |
| 20:44 | Part 1 of 2(3?) of adding the -asdict flag to the db eval command of the Tcl interface, as proposed in forum post dce85c5ab9f0bc10. This is the lowest-level part but it does nothing because the higher-level part does not yet exist to activate it, a notable consequence of which is that it's untested. Rename pArray to pTgtName because the former name is now confusingly incorrect. (check-in: 003e2c9bca user: stephan tags: tcl-cw) | |
| 17:13 | Flesh out the break-as-null test cases to better demonstrate how it compares to the default of returning an empty string. (check-in: ad1ae76ad1 user: stephan tags: tcl-cw) | |
| 16:49 | Allow Tcl-defined UDFs to 'break' to result in an SQL NULL, as per suggestion in forum post 585ebac2c48f1411. (check-in: 034211985d user: stephan tags: tcl-cw) | |
| 15:12 | Merge trunk into cygwin-fixes branch. 'make test' failure count = 1 (delete_db-1.3.0) both before and after the merge, (Leaf check-in: 7471088197 user: stephan tags: cygwin-fixes) | |

| 15:17 | Enhance sqlite3_rsync so that if the first attempt to invoke a copy of itself on the remote system using ssh fails, try again after augmenting the PATH. This enables sqlite3_rsync to work without the --exe option when the remote system is a Mac. (check-in: 38d4c94d8c user: drh tags: trunk) | |
| 10:55 | Fix a harmless redundant variable declaration in sqlite3_rsync. (check-in: f8f15eff6a user: drh tags: trunk) | |
| 10:49 | Addition summary results output when using -vvv on sqlite3_rsync. (check-in: c702999cfa user: drh tags: trunk) | |
| 10:35 | Promote the --protocol option to sqlite3_rsync from being an undocumented debug option to being a supported and user-visible option. This is sometimes needed to work around bugs in prior versions running on the remote. (check-in: 4855e04e44 user: drh tags: trunk) | |
| 08:17 | Enhance sqlite3_rsync (in a backwards-compatible way) so that it has the ability to send hashes for blocks of pages in addition to individual pages. By judicious use of this capability, network bandwidth requirement to sync two similar databases is reduced. (check-in: e5d87aaa8f user: drh tags: trunk) | |
| 07:00 | Improvements to protocol negotiation. (Closed-Leaf check-in: 4f5a06e420 user: drh tags: faster-rsync) | |

| 23:50 | Clean up command-line parsing. Add the undocumented -protocol option for debugging. (check-in: 2a52b174e6 user: drh tags: faster-rsync) | |
| 22:25 | Now appears to be working. More testing needed. Refinement of the version-2 algorithm needed. (check-in: cb035181d9 user: drh tags: faster-rsync) | |
| 18:32 | Bug fixes. Added new debugging features to better visualize the protocol. (check-in: c703306686 user: drh tags: faster-rsync) | |
| 17:39 | This is the start of an experiment in getting sqlite3_rsync to use less bandwidth when the two databases are very similar, by sending hashes over blocks of pages initially, rather than over individual pages, then requesting more detail when hashes do not match. (check-in: 266b4b8f01 user: drh tags: faster-rsync) | |
| 11:18 | Do not allow sqlite3_rsync to convert the replica from WAL-mode into DELETE-mode, as that can disrupt existing clients on the replica side. DELETE-mode to WAL-mode conversions are allowed, however. See forum thread 6b575b66156. (check-in: 660a035b6c user: drh tags: trunk) | |

| 18:07 | Enhance sqlite3_rsync so that, by default, it will sync non-WAL-mode database files. Add a new command-line option --wal-only that restricts the sync to WAL-mode databases only (the former default). Improve command-line option parsing so that only a single "-" is required before each option. (check-in: 4b53603fe4 user: drh tags: trunk) | |
| 16:07 | Allow sqlite3_rsync to work on non-WAL-mode databases, as long as the --wal-only flag is not used. (Closed-Leaf check-in: e4126dcd1e user: drh tags: rsync-non-wal-mode) | |
| 16:02 | Mistake: Started from the wrong check-out. (Leaf check-in: 9f88f73ce3 user: drh tags: mistake) | |
