| ||
| 15:53 | Have the planner ensure that if one scan uses a subset of the WHERE clause of another, that scan is estimated to cost less and return fewer rows. (check-in: c7b34930 user: dan tags: trunk) | |
|
2021-08-30

| 17:09 | • Edit [46e28cbcf6044b36|46e28cbc]: Edit check-in comment. (artifact: 30381eee user: dan) | |
| 17:02 | Do not disable a rowid=? term used to drive an IPK index if it is a transitive constraint. Commit [f1f9b5de] made the same change for non-IPK indexes. (check-in: 46e28cbc user: dan tags: trunk) | |
|
2021-08-27
| ||
| 11:26 | Patch lemon to fix "error" token handling, according ot forum post e680f42f53090061. (check-in: 106b5e53 user: drh tags: trunk) | |
|
2021-08-26
| ||
| 21:12 | Change the structuree exception handler in wal.c to catch EXCEPTION_IN_PAGE_ERROR instead of EXCEPTION_ACCESS_VIOLATION. (check-in: 0c6ab539 user: dan tags: wal-shm-exceptions) | |

| 17:07 | Correctly preserve the collating sequence for a column when changing its datatype. Fix for the problem reported by forum post 36be3d3a08da9d92. Test cases in TH3. (check-in: c7f0813c user: drh tags: trunk) | |
|
2021-08-23
| ||
| 15:56 | Fix a typo in a comment. No changes to code. (check-in: d953646a user: drh tags: trunk) | |
| 10:28 | Back out the change that allows typeless columns in strict tables. Replace that capability with an ANY type for strict tables that will accept any datatype with BLOB affinity. (check-in: d8fd1a2b user: drh tags: trunk) | |
|
2021-08-21
| ||
| 20:54 | Allow typeless columns in STRICT tables that are able to accept any data type. (check-in: 1e2dcc2d user: drh tags: trunk) | |
| 16:45 | • Edit [600f1991e5c0a5d8|600f1991]: Edit check-in comment. (artifact: e1bacf78 user: drh) | |
| 16:42 | 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. This fixes the assertion fault described by forum post cfcb4b461d. The problem goes back to check-in [6e6b3729e0549de0]. (check-in: 600f1991 user: drh tags: trunk) | |
| 15:49 | Add test cases to ensure that there is at least one test that causes an exception to be thrown from each SEH_INJECT_FAULT macro. (check-in: e480146f user: dan tags: wal-shm-exceptions) | |
|
2021-08-20
| ||
| 19:51 | Improvement to error handling in Lemon. No impact on SQLite. Forum post 2f468f43cbc48d7f (check-in: 18cc2f85 user: drh tags: trunk) | |
| 18:18 | Use VVA_ONLY() instead of TESTONLY() in SEH macros so that the build works for coverage testing. (check-in: 9e9d5b56 user: drh tags: wal-shm-exceptions) | |
| 17:23 | Add missing SEH_INJECT_FAULT macros. (check-in: 27e9bdb3 user: dan tags: wal-shm-exceptions) | |
| 16:19 | Add some assert() statements and fix small issues with code on this branch. (check-in: bd9b373b user: dan tags: wal-shm-exceptions) | |
| 15:44 | Support for STRICT tables. A table with the STRICT option only allows a few core datatypes on columns and enforces those types rigidly. Also, PRIMARY KEY columns must be NOT NULL. (check-in: f9c1d344 user: drh tags: trunk) | |
| 11:50 | Fix a problem on this branch causing checkpoints that do not proceed because they can't get the CHECKPOINT lock to return incorrect output values. (check-in: 5a98820c user: dan tags: wal-shm-exceptions) | |
| 08:05 | Improved error messages for the SQLITE_CONSTRAINT_DATATYPE error. (Closed-Leaf check-in: 39abca01 user: drh tags: strict-tables) | |
| 01:12 | Do not allow the xfer-optimization to move the content of an ordinary table into a strict table. (check-in: 1ed1b594 user: drh tags: strict-tables) | |
|
2021-08-19
| ||
| 23:10 | Enable this branch to run both with and without the -DSQLITE_USE_SEH option. (check-in: 840e0a14 user: drh tags: wal-shm-exceptions) | |
| 21:01 | If SQLITE_USE_SEH is defined, handle structured-exceptions thrown by MSVC builds if the *-shm file mapping is accessed after it becomes invalid for some reason. (check-in: 5c5fa470 user: dan tags: wal-shm-exceptions) | |
| 16:29 | Improved comments. Fewer opcodes for integrity_check on strict tables. (check-in: 4ee57fb5 user: drh tags: strict-tables) | |
| 02:58 | Enhance PRAGMA integrity_check so that it verifies the datatype of all columns in STRICT tables. (check-in: 97c9248b user: drh tags: strict-tables) | |
| 00:24 | STRICT tables require all fields of the PRIMARY KEY to be NOT NULL. (check-in: 5efdf9ac user: drh tags: strict-tables) | |
|
2021-08-18
| ||
| 23:00 | Merge the WITHOUT ROWID, NOT NULL ON CONFLICT bug fix into the strict-tables branch. (check-in: 7ee01ee4 user: drh tags: strict-tables) | |
| 22:27 | • Fixed ticket [f2be158c]: ON CONFLICT on a PK column in a WITHOUT ROWID table does not work plus 5 other changes (artifact: cddd457c user: drh) | |
| 22:26 | Fix ON CONFLICT clause processing for NOT NULL constraints of PRIMARY KEY columns on WITHOUT ROWID tables. Ticket [f2be158c57aaa8c6] (check-in: 13abba09 user: drh tags: trunk) | |
| 22:16 | • New ticket [f2be158c] ON CONFLICT on a PK column in a WITHOUT ROWID table does not work. (artifact: a0e62f7b user: drh) | |
| 19:22 | Trying to insert an incorrect datatype into a STRICT table raises an SQLITE_CONSTRAINT_DATATYPE error. Seems to work, though lots more testing is needed. (check-in: a19305e5 user: drh tags: strict-tables) | |
| 13:13 | 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? This branch seeks to explore that question. (check-in: 78732b9f user: drh tags: strict-tables) | |
| 12:05 | Rename the Column.eType field to Column.eCType - with an extra "C". (check-in: b9b0dcd5 user: drh tags: trunk) | |
|
2021-08-17
| ||
| 19:59 | Fix an off-by-one error in the error-handling logic of the Lemon parser-generator. This does not affect SQLite. Forum cff80737bf. (check-in: 7cca8080 user: drh tags: trunk) | |
|
2021-08-12
| ||
| 14:22 | By default, do not use memory mapping to access the temporary files used for external sorts. The old behaviour (to use memory mapping by default) may be restored by building with SQLITE_ENABLE_SORTER_MMAP defined. (check-in: 306694df user: dan tags: trunk) | |
|
2021-08-11
| ||

| 18:44 | If the special "sqlite_rbu_replace_hack" table is present in an RBU database, use REPLACE instead of INSERT when writing index entries to imposter tables. (check-in: 4b73e151 user: dan tags: rbu-replace-hack) | |
| 18:43 | During DELETE, if an index entry is missing, do not raise the SQLITE_CORRUPT_INDEX error (added by [f339f31f9e9a856b]) if in "PRAGMA writable_schema=ON" mode. (check-in: 19e56291 user: drh tags: trunk) | |
| 13:48 | Do not apply the push-down optimization to CTE subqueries that will be reused in other contexts in where the same optimization is unlikely to be valid. Fix for the bug reported by forum post d496c3d29bc93736. (check-in: a7ce29a6 user: drh tags: trunk) | |
| 13:19 | Improved comment on the OP_OpenDup used to get a new cursor for a reused materialized CTE. (check-in: b1926cc0 user: drh tags: trunk) | |
|

| 18:07 | Ensure that the pcache1 cache size does not get so big that it overflows the integer that is keeping track of the cache size. (check-in: bf9d70fc user: drh tags: trunk) | |
| 17:45 | Fix harmless compiler warnings and improve the presentation for the new --threadsafe option to the CLI. (check-in: 7929dc2f user: drh tags: trunk) | |
| 17:37 | Undocumented "--threadsafe N" option added to the CLI for testing purposes. One of SQLITE_CONFIG_SINGLETHREAD, _MULTITHREAD, or _SERIALIZED is called depending on the value of the N integer. (check-in: 2d8f297c user: drh tags: trunk) | |
| 17:36 | Improved Hamming bit-distance between the SQLITE_STATE constants. (check-in: 5100b045 user: drh tags: trunk) | |

|
2021-08-06

|
2021-08-05
| ||
| 15:27 | Store the collating sequence name for each column of a table as an extension to the column name, for an additional savings in the heap space needed to hold the schema. (check-in: 832ac4c1 user: drh tags: trunk) | |
|
2021-08-04

| 13:42 | Always prefer built-in SQL functions over app-defined SQL functions within sqlite3NestedParse(). Formerly this was the case for a few calls to sqlite3NestedParse(), but not for all of them. (check-in: 164662ef user: drh tags: trunk) | |
| 11:29 | Avoid using LIKE with the target db in RBU. It is possible the user may issue "PRAGMA case_sensitive_like = 1" or override the like() user function, causing RBU to malfunction. (check-in: 7cbd8cd5 user: dan tags: trunk) | |
|
2021-08-03
