|
2024-02-03

| 05:58 | WASM: various build cleanups and add initial infrastructure for a build which elides the oo1 API and its dependents (worker1 and promiser). Sidebar: an attempt was made to move generation of the build rules to an external script, but the mixed-mode make/script was even less legible than the $(eval) indirection going on in the makefile. (check-in: 563d3131 user: stephan tags: trunk) | |

| 15:54 | Simplify a memcpy() in defragmentPage(). It now might copy more content than is strictly necessary, but runs faster and uses less code space. Possible reasons for the improved performance: (1) the copy is now always 8-byte aligned, (2) fewer intermediate results are required which means less register pressure which helps the compiler to optimize the subroutine.

| 00:45 | When the sqlite_stat1 data is missing for some indexes of a table but is present for the table itself or for other indexes in the same table, then do not let the estimated number of rows in that table get too small, as doing so can deceive the query planner into ignoring a perfectly good index.

2019-02-21
| ||
| 16:41 | Detect oversized strings in the OP_String opcode even if the P4 argument is originally UTF8 and has to be converted to UTF16 to match the database file and that conversion causes the string to become shorter and cross below SQLITE_LIMIT_LENGTH threshold. This might fix an OSSFuzz problem that we have been so far unable to reproduce. (check-in: c13d5639 user: drh tags: trunk) | |

| 13:55 | Progress handler improvements: (1) Invoke the callback after OP_Program opcodes (2) Invoke the callback multiple times in a row to catch up after a long run of no progress checks. (check-in: 0c5db18d user: drh tags: trunk) | |
| 12:52 | When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. This is a better fix for ticket [df46dfb631f75694] than the previous fix that is now on a branch as it preserves the full optimization of check-in [e130319317e76119].

Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. (check-in: 90cf32cd user: drh tags: trunk) | |

2016-06-23
| ||
| 16:48 | Update the sqldiff utility so that if the --vtab switch is specified "rtree", "fts3", "fts4" and "fts5" tables are diff'd directly and the underlying real database tables ignored. Without this switch, all virtual tables are ignored and the diff is performed on the underlying real tables. (check-in: b8671e94 user: dan tags: trunk) | |

| 14:04 | Add the "dbhash.exe" utility program that computes a SHA1 hash over the invariant content of an SQLite database file. Free space in the file, the page size, auto_vacuum status, text encoding, and so forth do not change the hash. Only the content matters. (check-in: f48a4ad3 user: drh tags: trunk) | |

| 20:27 | Translate filenames of the form "/c:/*" into just "c:/*" on WinRT and Cygwin. (SQLite has long done this for Win32/WinNT.) (check-in: f8470ffc user: drh tags: trunk) | |
| 18:17 | Fix lempar.c so that the shift-reduce optimization works for error processing. This is a Lemon issue only and has no impact on SQLite. (check-in: 3665a2f5 user: drh tags: trunk) | |
| 13:24 | Initialize the yyerrcnt variable in the lemon parser template. This has no effect on SQLite itself. (check-in: 45531654 user: drh tags: trunk) | |
| 01:54 | Small performance boost and size decrease in sqlite3BtreeMovetoUnpacked(). (check-in: e106a77d user: drh tags: trunk) | |
| 01:48 | Small performance improvement in the LIKE function. (check-in: 5fb0c354 user: drh tags: trunk) | |
| 01:14 | Btree interface refactoring: (1) The sqlite3BtreeKeySize() interface is renamed to sqlite3BtreeIntegerKey() and modified to work only for table btrees with a rowid. (2) The sqlite3BtreeDataSize() interface is renamed to sqlite3BtreePayloadSize() and modified to work with any btree. (3) The sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() routines are combined into a single sqlite3BtreePayloadFetch() routine. The result of these changes is a smaller binary and fewer CPU cycles needed to run queries. (check-in: 2d831074 user: drh tags: trunk) | |

| 18:44 | Add support for virtual tables using a WITHOUT ROWID schema. This merge also includes enhancements to the CSV extension, which is used for testing of the new WITHOUT ROWID virtual table mechanism. (check-in: aa7e9d0c user: drh tags: trunk) | |
| 13:35 | Enhance the sqlite3_load_extension() interface to permit extensions to return SQLITE_OK_LOAD_PERMANENTLY which will prevents unloading when the database connection closes. (check-in: 5908aa4d user: drh tags: trunk) | |

| 18:50 | Minor change to the walcrash4.test module so that it works when SQLITE_DEFAULT_WAL_SYNCHRONOUS is set to something other than 2. (check-in: 61e239bc user: drh tags: trunk) | |
| 16:20 | Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary. This means that if a power failure or OS crash occurs very soon after such a transaction is committed, it may be lost following system recovery. (check-in: 37de3eab user: dan tags: trunk) | |
| 00:40 | Improvements to the initialization of the push-down automoton for the Lemon-generated parser. Smaller and faster. (check-in: 3b28b68e user: drh tags: trunk) | |

2016-05-23
| ||
| 21:56 | Use a pointer to the top of the stack rather than an index into the stack in the Lemon-generated parser template, for about 6.6% parser performance gain. (check-in: 3c2a7705 user: drh tags: trunk) | |
