2021-09-29
| ||
| 20:17 | Add NEVER() macros on branches that are not reachable since [a0df216f7c3f8963]. (check-in: 5d771f35 user: drh tags: trunk) | |
| 14:01 | Improved testability of changes from check-in [255b0eeed113d83b]. (check-in: bbfd083c user: drh tags: trunk) | |
| 14:01 | • Edit [df0d7e36dbf98ab5|df0d7e36]: Edit check-in comment. (artifact: a95358fd user: drh) | |
|
2021-09-25
| ||
| 20:28 | Load recent dbsqlfuzz cases into test/fuzzdata8.db. (check-in: 7a8fcf6d user: drh tags: trunk) | |
| 17:07 | Add const to parameters on various internal interfaces. (check-in: 70c221c5 user: drh tags: trunk) | |

| 19:57 | Dbsqlfuzz (a097eaad43c3c845b236126df92fb49b25449b0c) found a way to reach the assert() that was added to sqlite3_declare_vtab() by [eb94f4a8174436b1]. This check-in fixes the problem. (check-in: 857d26a6 user: drh tags: trunk) | |
| 16:14 | Add lots of new "const" on internal function parameters. There is opportunity for many more - this is a work in progress. (check-in: a3c71a67 user: drh tags: trunk) | |
| 12:59 | Ensure that sqlite_stat1 and sqlite_stat4 are ordinary tables (not views or virtual tables) before trying to load them (dbsqlfuzz bc02a0cde82dee801a8d6f653d2831680f87dca1). This prevents sqlite3_declare_vtab() from running with db->init.busy turned on. Even so, enhance sqlite3_declare_vtab() to be able to deal with db->init.busy being on, in case there are undiscovered paths to that state. Each of these two changes are independently sufficient to prevent the problem fixed by the previous check-in [c7560c1329965ab5] but there is no harm in keeping that third layer of protection in place. (check-in: eb94f4a8 user: drh tags: trunk) | |
| 02:14 | Ensure that the db->init.azInit array is initialized at all times. dbsqlfuzz 0ad6d441f9bf3dfc32626a9900bc1700495b16f9 (check-in: c7560c13 user: drh tags: trunk) | |

2021-09-22
| ||
| 14:43 | Fix harmless compiler warnings. (check-in: d678ecca user: drh tags: trunk) | |
| 14:26 | For shell.c.in, define CHAR_BITS to 8 on platforms that do not have that value set by default. This fixes the build on older machines. (check-in: 96610cc8 user: drh tags: trunk) | |
| 13:43 | Fix harmless compiler warnings in shell.c.in, and a compiler warning in sqlite3expert.c which is a real error, though also harmless. (check-in: 56da0e9c user: drh tags: trunk) | |
| 13:07 | Fix an incorrect assert() in rtree that was added recently by [f7ad73c49507c943]. Change it to testcase(). (check-in: 3aa0bf3a user: drh tags: trunk) | |
| 10:57 | Enhance the TCL-based test harness so that it is possible to list multiple test modules on the "testfixture" command-line and have them all run. For example: "./testfixture test/shell*.test" (check-in: 45caf9b8 user: drh tags: trunk) | |
| 10:28 | Use sqlite3_snprintf() for the ".changes" output formatting in the shell because it now uses %lld, and some older C compilers do not understand that construct. (check-in: 53dadf80 user: drh tags: trunk) | |
|
2021-09-21
| ||
| 17:26 | Add the "PRAGMA table_list" command with its corresponding eponymous table-valued function: "pragma_table_list". (check-in: 2c0e7ae5 user: drh tags: trunk) | |
|
2021-09-17
| ||
| 13:07 | Make the affinity() function available even if compiled without SQLITE_DEBUG. Surround the implementation of all test-only SQL functions with #ifndef SQLITE_UNTESTABLE. (check-in: b7e00ef8 user: drh tags: trunk) | |
|
2021-09-16
| ||
| 22:23 | The dbsqlfuzz fuzzer found a refutation for a recent ALWAYS() macro. (check-in: ebfc18aa user: drh tags: trunk) | |
| 20:16 | Minor changes to rtree.c so that we can get full branch coverage even when it is compiled without geopoly. (check-in: f05ae9b5 user: drh tags: trunk) | |
| 17:02 | Add a single new ALWAYS() to rtree.c, with justification. (check-in: 778e4499 user: drh tags: trunk) | |
| 16:41 | Add a tag comment in rtree.c. No changes to code. (check-in: 213410fa user: drh tags: trunk) | |
| 14:07 | Mark an unreachable branch in rtree. (check-in: e6c4afd5 user: drh tags: trunk) | |
| 13:52 | Back out a couple of ALWAYS() macros from [4fab9089868bbb05]. Test case added to TH3. (check-in: d26963a5 user: drh tags: trunk) | |
| 13:20 | For ALTER TABLE RENAME COLUMN, do not try to filter virtual tables out of calls to sqlite_rename_column(). Let the function filter them itself. The WHERE clause can mistakenly let virtual tables through if the sqlite_schema table is corrupt. The sqlite_rename_column() function must deal with them. We might as well let it deal with them always. (check-in: 7c82b43b user: drh tags: trunk) | |
| 12:33 | Under SQLITE_DEBUG with PRAGMA vdbe_trace=ON, show an output line if the VDBE aborts for any reason. (check-in: 7e3d6810 user: drh tags: trunk) | |
| 07:32 | Simplify the routine that attempts to estimate the size of an rtree index by looking at the sqlite_stat1 entry for the %_rowid table. (check-in: 06c329c1 user: drh tags: trunk) | |
| 05:39 | Mark various unreachable branches in rtree.c with ALWAYS() or NEVER(). (check-in: 4fab9089 user: drh tags: trunk) | |
| 05:24 | New ALWAYS() and assert() to mark unreachable branches in rtree.c. (Closed-Leaf check-in: f7ad73c4 user: drh tags: tree-testing) | |
|
2021-09-15
| ||
| 19:53 | In rtree.c, remove an incorrect ALWAYS(). Add other ALWAYS() and NEVER(). (check-in: cbaac887 user: drh tags: tree-testing) | |
| 19:41 | • Edit [fbba89dac9591c56|fbba89da]: Move to branch tree-testing. (artifact: bd3d0917 user: drh) | |
| 19:13 | Add more ALWAYS() macros on unreachable branches in rtree.c (check-in: fbba89da user: drh tags: tree-testing) | |
| 16:20 | Fix the xBestIndex method on rtree so that it correctly recognizes that rowid=? works the same as id=?. (check-in: c74c07cc user: drh tags: trunk) | |
| 15:56 | Add ALWAYS() macros on some unreachable branches in rtree. (check-in: 9123f680 user: drh tags: trunk) | |
| 13:09 | Simplify some of the corrupt shadow-table detection logic in rtree. (check-in: 0c4f37aa user: drh tags: trunk) | |
|

|
2021-09-13

| 13:53 | Fix an incorrect comment and possible integer overflow in pager resulting from check-in [23ca23894af352ea]. Problem reported by forum post e2ea1a3f61. Also change the datatype of Pager.pageSize to i64 even though page size never exceeds 65536, in order to help prevent future problems of this kind. (check-in: f4a552ed user: drh tags: trunk) | |
|
2021-09-10
| ||
| 01:02 | Back out changes [00286ca5d998d802] and [6844ede29e1dac93] (replacing the associated branches with NEVER()) and add a single new test to btreeOverwriteCell() that detects when an overflow pages is also mapped into a b-tree page and raises and immediate SQLITE_CORRUPT error before making any changes. dbsqlfuzz 81791bd980fe6935ff2c7334ec8bef11c1c12b82 and others. (check-in: 32210fa4 user: drh tags: trunk) | |
|
2021-09-09
| ||
| 19:19 | Remove a NEVER() in btree that is sometimes reachable. dbsqlfuzz b9140023005430654c8fe544cf0a082ef8d561c1. (check-in: 6844ede2 user: drh tags: trunk) | |
| 18:06 | Avoid masking off an OOM fault in rtreecheck(). (check-in: 3ebfe712 user: drh tags: trunk) | |
| 14:03 | Improved database corruption detection in the editPage() subroutine of the btree rebalancer. dbsqlfuzz f035b1b5a100a5f0cffb95c958b6c67d7c5eaf1f. (check-in: 00286ca5 user: drh tags: trunk) | |
|
2021-09-08
| ||
| 19:25 | Fix PRAGMA integrity_check so that it does not try to enforce types on ANY columns in a STRICT table. (check-in: 57384fda user: drh tags: trunk) | |
|
2021-09-07
| ||
| 19:23 | New test cases added to fuzzdata8.db. No code changes. (check-in: 51e5aada user: drh tags: trunk) | |
| 15:41 | Fix a potential NULL pointer deference in the LIKE optimization. The problem was introduced by the addition of generated columns in check-in [b855acf1831943b3] (SQLite version 3.31.0, 2020-01-22). Reported by Wang Ke in [forum/forumpost/699b44b3ee|forum post 699b44b3ee]. (check-in: b9417d40 user: drh tags: trunk) | |

|
2021-09-03
