Add NEVER() macros on branches that are not reachable since [a0df216f7c3f8963]. (check-in: 5d771f35 user: drh tags: trunk)
19:18
Fix a typo in altertab3.test. (check-in: 18d38b13 user: dan tags: trunk)
19:15
Have the dbstat module arrange things internally so that there are 256 addressable bytes following each page buffer. This way, small buffer overreads caused by corrupt database pages do not lead to undefined behaviour. (check-in: c4c705ab user: dan tags: trunk)
18:33
Fix another problem with ALTER TABLE and vector UPDATE statements within triggers. (check-in: a0df216f user: dan tags: trunk)

2021-09-28
10:44
Fix a potential ALTER TABLE problem with expressions like ( (<sub-select>) IN () ). (check-in: df0d7e36 user: dan tags: trunk)
2021-09-27
17:11
Have the dbstat virtual table take a copy of each page buffer that it traverses instead of just a reference to the page-cache object. This avoids problems if an error causes transaction rollback while a dbstat cursor is open. dbsqlfuzz crash-417224040fee04f0f0e62b70265c518893b08769. (check-in: 6ab25f8b user: dan tags: trunk)
15:44
Fix a problem in ALTER TABLE causing table or column references in sub-selects ton the RHS of a vector SET clause in an UPDATE within a trigger (i.e. "SET (a,b) = ( (SELECT...), <expr> )"). (check-in: 255b0eee user: dan tags: trunk)
2021-09-25
20:28
Load recent dbsqlfuzz cases into test/fuzzdata8.db. (check-in: 7a8fcf6d user: drh tags: trunk)
20:19
Fix a memory leak in rtree triggered by corrupt database records. dbsqlfuzz 397ad036a9013d7318da30ef84947d2baaaa6d6c. (check-in: 706322c2 user: dan tags: trunk)
18:21
Fix a bad interaction between the pager cache and the dbstat module that could lead to a malfunction following an OOM. dbsqlfuzz 9ed3e4e3816219d3509d711636c38542bf3f40b1. (check-in: e03554a6 user: dan tags: trunk)
17:07
Add const to parameters on various internal interfaces. (check-in: 70c221c5 user: drh tags: trunk)
2021-09-24
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)

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
20:03
Fix .expert name collision bug reported at https://sqlite.org/forum/forumpost/05e6f32984561f57?t=h (check-in: 4a3f98ad user: larrybr tags: trunk)

Add tests for legacy geometry callbacks to rtreedoc2.test. (check-in: 6ad00e52 user: dan tags: trunk)
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)
19:50
Add tests to rtreedoc.test. (check-in: b18c6ec4 user: dan tags: trunk)

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)
14:17
Add a reference counter to a structure used internally by the Tcl interface so that it does not segfault if the database connection is closed from any of the various callback scripts that may be invoked. (check-in: e54a33ce user: dan tags: trunk)
14:07
Mark an unreachable branch in rtree. (check-in: e6c4afd5 user: drh tags: trunk)

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)

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)

Defer deleting subqueries in the compound-SELECT code generator until the end of code generation, in order to avoid deleting expressions out from under the aggregation function sanity checking assert()s that occur near the end of SELECT code generation.

What would it be like if you could add the keyword "STRICT" after a CREATE TABLE statement to cause the table to (1) allow only a few well-defined datatypes, (2) rigidly enforce those types, (3) require NOT NULL on PK columns, (4) always enforce foreign key constraint, and so forth?

Improved rebustness in sqlite3ExprListDup() when it contains a vector assignment from an UPDATE where the initial term is omitted. This can happen during a UNION ALL query flattening while processing a virtual table update in which the first term of the vector is repeated. Forum post 16ca0e9f32.

Ensure that TK_SELECT_COLUMN Expr nodes always have their iTable field set to to the number of columns in the vector. This is not strictly necessary. It just simplifies the state description and make the code easier to reason about. (check-in: 026f08d4 user: drh tags: trunk)

The OP_ReopenIdx opcode should clear the cursor if the cursor is being reused. This prevents leaving the cursor in an initialized state which could cause problems for a subsequent OP_SeekScan opcode.
