| 16:22 | [73362c0df0] part of check-in [6c00e88ebd] Add the SQLITE_INDEX_SCAN_HEX bit to the sqlite3_index_info.idxFlags bitmask. When set, this bit causes the EXPLAIN QUERY PLAN output to show the idxNum value in hex rather than in decimal. This is purely a debugging aid. (check-in: [6c00e88ebd] user: drh branch: trunk, size: 29423) | |
|
2023-10-06
| ||
| 12:51 | [3b677254d5] part of check-in [f3b3d712d6] Ensure that all fields of static sqlite3_module objects are explicitly initialized, in order to hush-up nuisance compiler warnings. (check-in: [f3b3d712d6] user: drh branch: trunk, size: 29376) | |
|
2022-12-23
| ||
| 14:49 | [ec92074baa] part of check-in [c14bbe1606] Fix lots of harmless, nuisance compiler warnings, mostly unused parameter warnings in extensions. (check-in: [c14bbe1606] user: drh branch: trunk, size: 29325) | |
|
2022-12-02
| ||
| 15:31 | [a56a7ad116] part of check-in [5652154a8c] Use sqlite3_result_int64() instead of sqlite3_result_int() when returning potentially large values from the DBSTAT virtual table, to avoid integer overflows in the result. Forum post ada2ab044f. (check-in: [5652154a8c] user: drh branch: trunk, size: 29268) | |
|
2022-07-22
| ||
| 20:24 | [6a78b43639] part of check-in [57beb700c0] Add experimental 'xShadowName2' method for virtual table modules. (check-in: [57beb700c0] user: mistachkin branch: xShadowName2, size: 29311) | |
|
2021-09-29
| ||
| 19:15 | [861e08690f] part of check-in [c4c705abc6] 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: [c4c705abc6] user: dan branch: trunk, size: 29258) | |
|
2021-09-27
| ||
| 17:11 | [bea044cfe9] part of check-in [6ab25f8bd5] 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: [6ab25f8bd5] user: dan branch: trunk, size: 28768) | |

|
2020-03-19
| ||

|
2020-01-04
| ||
| 19:14 | [5125f559b3] part of check-in [5b246b47ae] Fix DBSTAT so that it returns no rows, rather than an error when the WHERE clause is "schema=NULL". (check-in: [5b246b47ae] user: drh branch: trunk, size: 27431) | |
| 18:38 | [bf7fbea4ed] part of check-in [cfff5cb227] Omit the omit flat from eq constraints on column "name" of dbstat virtual tables. Fix for [74a4c386]. (check-in: [cfff5cb227] user: dan branch: trunk, size: 27560) | |
| 14:00 | [427b13c258] part of check-in [74ef6f2b6d] Omit the omit flag from eq constraints on column "aggregate" of dbstat virtual tables. Fix for [727074e2]. (check-in: [74ef6f2b6d] user: dan branch: trunk, size: 27778) | |

| ||
| 23:01 | [9ad3f2d9d1] part of check-in [31942b3dd3] Initial code to make shadow tables read-only to ordinary SQL. The now xShadowName method is added to the sqlite3_module object and is used to identify potential shadow tables. The SQLITE_PREPARE_SHADOW argument to sqlite3_prepare_v3() is defined. It is designed to permit writing to shadow tables, but is currently an unused placeholder. (check-in: [31942b3dd3] user: drh branch: read-only-shadow, size: 23418) | |
