| ||
| 18:31 | Remove the requirement to open the wal file before sqlite3_snapshot_recover() is called. Also add some comments to new functions. (check-in: 28393c413c user: dan tags: serializable-snapshot) | |
| 17:30 | Test some extra error conditions in sqlite3_recover_snapshot(). (check-in: db314213c0 user: dan tags: serializable-snapshot) | |
| 17:20 | Add another fault-injection test for sqlite3_snapshot_recover(). (check-in: 7e04040613 user: dan tags: serializable-snapshot) | |
| 16:35 | Fix a problem causing sqlite3_snapshot_recover() to return SQLITE_IOERR_SHORT_READ. (check-in: 525f75fa9f user: dan tags: serializable-snapshot) | |
| 14:53 | Fix a bug in sqlite3_snapshot_recover() that could cause subsequent read transactions to use out-of-data cache entries. (check-in: 9abeb7980a user: dan tags: serializable-snapshot) | |
|
2016-11-18
| ||
| 20:49 | Add experimental sqlite3_snapshot_recover() API. (check-in: 174a6076a8 user: dan tags: serializable-snapshot) | |
| 18:43 | Require that the database handle be in autocommit mode for sqlite3_snapshot_get() to succeed. This is because it may open a read transaction on the database file. (check-in: 83b658dad0 user: dan tags: serializable-snapshot) | |
| 18:22 | Add tests for snapshot interfaces. (check-in: 1f7ee7af7b user: dan tags: serializable-snapshot) | |
| 14:38 | Enhance existing snapshot tests to serialize/deserialize snapshots. No new tests. (check-in: 16b9bf9274 user: dan tags: serializable-snapshot) | |

| ||
| 21:52 | Experimental changes for faster in-memory DB operation for large databases. (Closed-Leaf check-in: 4fe94b0f18 user: drh tags: memdb-opt) | |
| 20:05 | Fix a problem in rtreeD.test causing it to fail in OMIT_BUILTIN_TEST builds. (check-in: d6b3779e6d user: dan tags: trunk) | |
| 14:02 | When opening the *-shm file for a readonly database, try to open it in read-write mode before falling back to readonly. This is in case some other read/write connection within the same process uses the same file descriptor. (check-in: a07c581e88 user: dan tags: apple-osx) | |
| 13:54 | Change the --enable-debug option on configure so that it enables the ".selecttrace" and ".wheretrace" commands in the command-line shell. (check-in: 2331192b4c user: drh tags: trunk) | |
| 13:13 | Disable the query flattener optimization for SELECT statements that are on the RHS of vector IN operators. This is a hack that fixes the bug described in ticket [da7841375186386c]. A better solution that does not disable the query flattener is needed, but this will server for the time being. (check-in: 005d5b8706 user: drh tags: trunk) | |

| ||
| 21:17 | Add a needed #include to speedtest1.c. (check-in: 77aeb705c3 user: drh tags: trunk) | |
| 17:37 | Experimental changes toward making snapshots serializable. (check-in: b6a81fa1fc user: drh tags: serializable-snapshot) | |
| 04:00 | Change the OP_Last opcode so that it is a no-op if the cursor is already pointing at the end of the b-tree. (check-in: 663473850c user: drh tags: trunk) | |
| 02:46 | Make the VACUUM command about 9% faster by avoiding unnecessary calls to sqlite3BtreeMovetoUnpacked() while copying rowid tables. (check-in: 5ed0bd3876 user: drh tags: trunk) | |
|
2016-11-14

| 20:08 | Fix a potential use-after-free error during parsing of malformed CREATE TABLE statement. (check-in: c5dbc599b9 user: drh tags: trunk) | |
| 18:27 | Enhance fuzzcheck.c to accept database-specific configuration parameters in the option CONFIG table. Add the fuzzdata5.db fuzz database containing test cases from OSS-FUZZ. (check-in: a71fad4538 user: drh tags: trunk) | |
| 17:25 | Fix the ossfuzz.c test module so that it does not segfault after a "PRAGMA empty_result_callbacks=1;". Add the ossshell.c program for simple command-line testing of ossfuzz.c. (check-in: 6f2d43eca6 user: drh tags: trunk) | |
| 15:28 | Avoid unnecessary calls to sqlite3ExprCacheAffinityChange() when generating OP_MakeRecord opcodes that do not change any register affinities. (check-in: e211c579b2 user: drh tags: trunk) | |
| 08:19 | Fix an fts5 problem causing a crash in phrase queries where the first token of the phrase matches one or more rows but some other token within the phrase matches zero. (check-in: e78f6f3bbf user: dan tags: trunk) | |
|

| ||
| 20:37 | Fix harmless compiler warnings in test code for MSVC. (check-in: 7b76be4117 user: drh tags: trunk) | |
| 19:08 | Avoid storing redundant fields in sorter records when the sort-key and data have fields in common. (check-in: b835cf3e50 user: drh tags: trunk) | |
| 19:01 | Enhance the OP_IdxInsert opcode so that it can used unpacked key values if they are available. Update the code generator to take advantage of this new capability. The speedtest1.c test is about 2.6% faster as a result. Later: This also introduced bug [30027b613b]. Bummer. (check-in: 925840cfdb user: drh tags: trunk) | |
| 18:45 | Merge trunk with this branch. (Closed-Leaf check-in: dd62d2de6e user: dan tags: sorter-opt) | |
| 18:19 | Remove obselete and unused logic in the update code generator. Fix the sqlite3BtreeMovetoUnpacked() routine so that it remembers the rowid of the row that it landed on. (Closed-Leaf check-in: 1a587d72f9 user: drh tags: unpacked-IdxInsert) | |
| 18:08 | Reenable the SQLITE_EXPR_REF optimization for "SELECT DISTINCT ... ORDER BY" queries. (check-in: 6e2e9d383f user: dan tags: sorter-opt) | |
| 17:52 | Merge enhancements and bug-fixes from trunk. (check-in: 5515b827dc user: drh tags: unpacked-IdxInsert) | |
| 17:08 | Fix a problem with switching from wal to rollback mode when SQLITE_DBCONFIG_NO_CKPT_ON_CLOSE is configured. (check-in: 46e0016207 user: dan tags: trunk) | |
| 16:33 | Add the test/ossfuzz.c interface adaptor for OSS-FUZZ. Make previsions for testing the adaptor using fuzzcheck.c. (check-in: 119d6ef847 user: drh tags: trunk) | |
| 15:49 | Handle some obscure "row value misused" cases that could cause segfaults or assertion failures. (check-in: fba5fddb1c user: dan tags: trunk) | |
| 14:54 | Back out the "--raw" option on ".read" in the command-line shell. Instead, fix the command-line shell so that if EOF is reached without seeing a final semicolon, it goes ahead and passes the accumulated SQL text to SQLite. (check-in: f98c8ac8c4 user: drh tags: trunk) | |
| 09:51 | Add extra tests for the xBestIndex() virtual table method. (check-in: 642a8fba91 user: dan tags: trunk) | |
| 05:19 | In the command line shell, avoid using utf8_printf() in a couple places where it is superfluous. (check-in: 6311a8bdb1 user: mistachkin tags: trunk) | |
| 04:37 | Add the --raw option to the ".read" dot-command of the command-line shell, to cause the named file to be read and sent directly into sqlite3_exec() without any interpretation. (check-in: 09233770b2 user: drh tags: trunk) | |
| 03:37 | Take care not to try to generate code for the ATTACH and DETACH commands if there were syntax errors during parsing. Fix for ticket [2f1b168ab4d4844] (check-in: b0ff183b8f user: drh tags: trunk) | |

| 21:19 | Break up the sqlite3BtreeMovetoUnpacked() routine into an eponymous routine and sqlite3BtreeMovetoIntkey(). Each routine specializes in a single kind of btree. (Leaf check-in: 9a64a4f235 user: drh tags: split-moveto) | |
| 20:42 | Avoid a few unnecessary calls to sqlite3BtreeMovetoUnpacked(). (check-in: eac0e827a6 user: drh tags: unpacked-IdxInsert) | |
| 20:14 | Avoid storing redundant fields in sorter records when the sort-key and data have fields in common (as in "SELECT a FROM t1 ORDER BY 1"). (check-in: 0af62fdbd8 user: dan tags: sorter-opt) | |
| 17:01 | When doing a REPLACE on a WITHOUT ROWID table with no secondary indexes, bypass the OP_NoConflict/OP_Delete sequence and directly overwrite any preexisting row, for a performance increase. (check-in: f7041cbb63 user: drh tags: unpacked-IdxInsert) | |
| 16:07 | Remove C++ style comments. No code changes. (check-in: 42f8aa6231 user: drh tags: unpacked-IdxInsert) | |
| 14:24 | Add the unpacked key fields to OP_IdxInsert for INSERT and UPDATE statements. (check-in: 67602e40f1 user: drh tags: unpacked-IdxInsert) | |
|
2016-11-09
| ||
| 20:14 | Comment changes that attempt to better explain the behavior of the "seekResult" field on VdbeCursor objects and the seekResult parameter to sqlite3BtreeInsert() and the OPFLAG_USESEEKRESULT flag on insert opcodes. No changes to code. (check-in: 345b46be75 user: drh tags: unpacked-IdxInsert) | |
| 16:03 | Fix a simple comment typo. No changes to code. (check-in: 51d0aed8d6 user: drh tags: unpacked-IdxInsert) | |
