| 20:11 | Replace an conditional assignment that was made obsolete by [d4c193f0b49f4950] with an assert(). The conditional was added by [d6fd512f50513ab7] as a fix for tickets [c36cdb4afd504dc1], [4051a7f931d9ba24], and [d6fd512f50513ab7] which means now [d4c193f0b49f4950] is the correct fix for those tickets. that check-in (check-in: 44b5524d user: drh tags: trunk) | |

| 20:36 | When generated text JSON from JSONB, do not continue descending into nested structures after an error is seen. This avoids long loops and wait times. (check-in: 97666ec0 user: drh tags: trunk) | |
| 16:49 | Avoid a potential buffer overread when handling corrupt json blobs. (check-in: ac402cc5 user: drh tags: branch-3.45) | |
| 12:58 | When rendering JSONB back into text JSON, report an error if a zero-length integer or floating-point node is encountered. Otherwise, if the node occurs at the very end of the JSONB, the rendering logic might read one byte past the end of the initialized part of the BLOB byte array. OSSFuzz 66284.

| 11:35 | Allocate new parser stack space from the heap if needed, eliminating the possibility of a "parser stack overflow" error as long as heap memory is available. (check-in: d87a2054 user: drh tags: trunk) | |
| 02:21 | Optimizations to ParseFinalize() to make up for the extra cleanup associated with the allocated parser stack. This branch now runs faster than trunk and is less than 300 bytes larger. (Closed-Leaf check-in: f7290db6 user: drh tags: growable-parser-stack) | |
| 01:35 | Omit the "parser stack overflow" error message, since it no longer occurs. Replace it with an ordinary "out of memory". (check-in: 33f17ec2 user: drh tags: growable-parser-stack) | |

| 16:21 | In os_unix.c and os_win.c, do not allow xFetch() to return a pointer to a page buffer that is right at the end of the mapped region - if the database is corrupted in a specific way such a page buffer might be overread by several bytes. (check-in: 198a1daa user: drh tags: branch-3.44) | |
| 16:17 | In os_unix.c and os_win.c, do not allow xFetch() to return a pointer to a page buffer that is right at the end of the mapped region - if the database is corrupted in a specific way such a page buffer might be overread by several bytes. (check-in: d131cab6 user: drh tags: branch-3.45) | |

| 13:53 | When a JSON input is a blob, but it looks like valid JSON when cast to text, then accept it as valid JSON. This replicates a long-standing bug in the behavior of JSON routines, and thus avoids breaking legacy apps. (check-in: 4c2c1b97 user: drh tags: branch-3.45) | |
| 13:51 | When a JSON input is a blob, but it looks like valid JSON when cast to text, then accept it as valid JSON. This replicates a long-standing bug in the behavior of JSON routines, and thus avoids breaking legacy apps. Forum thread 012136abd5292b8d. (check-in: e5dc81d5 user: drh tags: trunk) | |

| 13:21 | If a BLOB looks like JSON when cast to text, then treat it as if it really were JSON. This replicates a long-standing bug in the JSON processing routines, and thereby avoids breaking legacy. (check-in: d79a3769 user: drh tags: blob-as-json) | |
| 11:18 | • Edit [65572223583d43e1|65572223]: Move to branch blob-as-json. (artifact: 82d8e0dd user: drh) | |

| 15:26 | Improved error message when a double-quoted string is used and it seems likely that the user wanted a single-quoted string literal. (check-in: 0a834bd8 user: drh tags: improved-dqs-error-msg, blob-as-json) | |
| 14:16 | The -DSQLITE_JSON_BLOB_INPUT_BUG_COMPATIBLE compile-time option causes blob inputs to JSON functions that are not JSONB to be processed as if they where text, immulating historical bugging behavior which some applications have come to rely upon. See forum thread 012136abd5292b8d for discussion. (check-in: 65572223 user: drh tags: blob-as-json) | |
| 12:56 | Fix userauth so that it works together with SQLITE_OMIT_SHARED_CACHE. (Forum post 0bfc5888a384d430). However, also change to code to issue a deprecation warning whenever SQLITE_USER_AUTHENTICATION is used. (check-in: 249048b0 user: drh tags: trunk) | |

| 18:21 | Fix a memory leak in new memdb1.test test cases that were added by [e638d5e408ea2e18]. No changes to SQLite itself. (check-in: bb2b7a65 user: drh tags: trunk) | |
| 16:38 | Make sure that %V and %G are testing for every since day in between 1970-01-01 and 2023-01-19. (check-in: 39c475f5 user: drh tags: trunk) | |
| 16:29 | Rig sqlite3_serialize() so that it will initialize a previously uninitialized database prior to serializing it, so that it does not have a zero-byte size and does not return NULL (except for OOM). Forum thread 498777780e16880a. (check-in: e638d5e4 user: drh tags: trunk) | |
| 15:13 | When doing a text-affinity comparison between two values where one or both have both a text and a numeric type, make sure the numeric type does not confuse the answer. This is a deeper fix to the problem observed by forum pose 3776b48e71. The problem bisects to [25f2246be404f38b] on 2014-08-24, prior to version 3.8.7. (check-in: 709841f8 user: drh tags: trunk) | |
| 13:18 | Ensure that the replace() SQL function always returns a TEXT value even when its first argument is numeric and its second argument is an empty string. Fix for the issue reported by forum post 3776b48e71. (check-in: 01868ebc user: drh tags: trunk) | |

| 12:00 | Fix the version number in the TEA configure script. This should have been changed by [1481baf3d55effcc] three check-ins ago. It is unclear how testing missed this. (check-in: eaf2cf73 user: drh tags: trunk) | |
| 00:31 | Implement a new algorithm for computing ISO week values in strftime() based on the idea (from Nuno Cruces) of shifting the date being tested to the Thursday of the same week. (check-in: b06ab46a user: drh tags: trunk) | |

| 19:20 | • Edit [ee34db31a0776ec0|ee34db31]: Mark "Closed". (artifact: 310125af user: drh) | |
| 19:20 | New logic to avoid using indexes that ANALYZE has identified as of little practical use. Also a performance optimization in ANALYZE. (check-in: bcac9375 user: drh tags: trunk) | |
| 17:58 | Remove some unnecessary computations from ANALYZE so that ANALYZE runs with fewer CPU cycles. These changes were spotted while working on the nearby enhanced-stat1 branch. So even if enhanced-stat1 is abandoned, that effort put into it will not have been in vain. (Closed-Leaf check-in: 5527e8c4 user: drh tags: avoid-low-quality-indexes) | |
| 17:48 | Extra steps taken to avoid using low-quality indexes in a query plan. This branch accomplishes the same end as the nearby enhanced-stat1 branch, but with much less change and hence less risk. (check-in: c030e646 user: drh tags: avoid-low-quality-indexes) | |
| 15:49 | Improved defenses against deliberately corrupted sqlite_stat1 tables. (Closed-Leaf check-in: ee34db31 user: drh tags: enhanced-stat1) | |
| 15:35 | Fix a harmless compiler warning. (check-in: b5aa1aea user: drh tags: enhanced-stat1) | |
| 14:13 | Omit the uneven=N argument in sqlite_stat1 and replace it with var=N1,N2,... so that the variation in each column is reported separately. Omit the "slow" argument from sqlite_stat1, computing that flag internally. PRAGMA stats is enhanced with a new column "est" that shows the aiRowLogEst array for each index after it has been modified by "var=..." and also the "slow" flag.
