| 02:05 | Add the "phase" output column on the COMPLETION table-valued function, for debugging. Improved comments on the implementation. check-in: 0e213555 user: drh tags: trunk | |
| 01:38 | The COMPLETION virtual table now looks at the names of databases, tables, and columns in addition to SQL keywords. check-in: 1cc97711 user: drh tags: trunk | |
| 00:09 | Incomplete implementation of the COMPLETION table-valued function. So far it only works for SQL keywords. check-in: caefbc72 user: drh tags: trunk | |

| 21:32 | Fix harmless compiler warnings in lsmtest. check-in: bd8a1fb9 user: mistachkin tags: trunk | |
| 20:39 | Fix errors in comments in the STMT virtual table. No code changes. check-in: 9a8f045d user: drh tags: trunk | |
| 20:33 | Minor cleanup and refactoring of the Win32 VFS for lsm1. check-in: bf7eda67 user: mistachkin tags: trunk | |
| 19:54 | Another spelling error in the README.md file. check-in: 05129374 user: drh tags: trunk | |
| 19:08 | Spelling error in README.md check-in: 12bc47c5 user: drh tags: trunk | |
| 19:07 | Yet another typo in README.md check-in: 75c9327b user: drh tags: trunk | |
| 19:05 | Fix another README.md typo. check-in: 20b1f0ef user: drh tags: trunk | |
| 19:03 | Fix an obsolete statement about Lemon in the README.md file. check-in: 4f6ce7a3 user: drh tags: trunk | |
| 18:57 | Cleanup header usage in lsmtest for files that require _O_BINARY. check-in: f3a6a64e user: mistachkin tags: trunk | |
| 18:52 | Updates to the repository README.md file. check-in: 7bfd3ab7 user: drh tags: trunk | |
| 18:33 | In LSM, avoid calling the VFS xTestLock method to test for a lock that conflicts with one held by the same process. The results of such a call are considered undefined (since they are different under win32 and posix). check-in: a82a9bea user: dan tags: trunk | |
| 18:04 | Add the "--newlines" option to the ".dump" command in the shell to disable the newline escaping mechanism. check-in: bde431b1 user: drh tags: trunk | |
| 17:00 | When multiple constraints need to be evaluated for a row, do any constraints that involve correlated subqueries last. Hence, the priority is index-covered constraints first, correlated subquery constraints last, and all others in the middle. This is a follow-on and improvement to the push-down optimization of check-in [d7bb79ed]. check-in: c4cb9048 user: drh tags: trunk | |
| 16:38 | Additional debugging Noop-comment in the constraint generator when wheretrace is enabled. Closed-Leaf check-in: 0ca7474f user: drh tags: defer-where-subqueries | |
| 15:26 | Small performance optimization in sqlite3WhereExprUsage(). check-in: 38edc677 user: drh tags: defer-where-subqueries | |
| 15:17 | Fix another problem on this branch. check-in: a4fc9811 user: dan tags: defer-where-subqueries | |
| 14:39 | Fix a problem causing non-covered WHERE terms to be evaluated before covered WHERE terms. check-in: 7d3cb39f user: dan tags: defer-where-subqueries | |
| 14:33 | When testing non-indexed WHERE constraints, test those that involve correlated sub-queries last of all. This increases the chances of not having to run the sub-query at all. check-in: 1f9c1f35 user: dan tags: defer-where-subqueries | |
| 13:24 | For sqlite3TreeView() debugging output, show the Expr.flags field on scalar subqueries. check-in: dc857a96 user: drh tags: trunk | |
| 12:07 | Update error message text for standard error codes to better describe the latest usage of those error codes. Modify sqlite3_open_v2() so that it does return a valid sqlite3 object in the event of SQLITE_MISUSE due to bad open flags, so that sqlite3_errmsg() does not report "out of memory" in that case. check-in: f27b6370 user: drh tags: trunk | |
| 11:17 | Remove the error message text from disused error codes such as SQLITE_EMPTY and SQLITE_FORMAT. check-in: 871752f2 user: drh tags: trunk | |
|

| 18:55 | Always make "column%d" column-names 1-based, never 0-based. check-in: 70096c50 user: drh tags: trunk | |
| 00:30 | Make sure the columns of a VALUES() clause are named "column%d" even if the VALUES() clause is a subquery in the FROM clause of an outer query. check-in: acf3b9cc user: drh tags: trunk | |
|
2017-07-08

| 22:47 | Basic test cases for PRAGMA secure_delete=FAST. check-in: 0c246017 user: drh tags: trunk | |
| 21:20 | Fix comment in the Win32 VFS for lsm1. check-in: 12a421bc user: mistachkin tags: trunk | |
| 21:15 | For lsmtest, use a more portable means of setting open() files to binary. check-in: aea6e0ff user: mistachkin tags: trunk | |
| 20:35 | Adjust copy_file() lsmtest function so it works properly for locked database files on Win32. check-in: 54a38555 user: mistachkin tags: trunk | |
| 20:06 | Add the "PRAGMA secure_delete=FAST" option, which overwrites most deleted content without increasing the amount of I/O. Deleted content might persist on the free page list, however. And extra CPU cycles are used for zeroing, of course. check-in: 38978ce6 user: drh tags: trunk | |
| 19:43 | Change the error message text for SQLITE_ERROR to omit the part about "missing database" as that meaning is now obsolete (since approx SQLite 2.0). check-in: 732f90d6 user: drh tags: trunk | |
| 19:22 | Fix typos in Win32 VFS for lsm1. check-in: 0961ec87 user: mistachkin tags: trunk | |

| 19:02 | Enhance the MSVC makefile 'clean' target to handle lsm1. check-in: 2d6faebc user: mistachkin tags: trunk | |
| 18:31 | Add support for LSM_DEBUG to the MSVC makefile for lsm1. check-in: 277a7fed user: mistachkin tags: trunk | |
| 18:06 | In the command-line shell, when running ".schema" give a sensible error when the database file is locked. check-in: cc329eb8 user: drh tags: trunk | |
| 17:57 | Fix the usleep() macro in the Win32 test code for lsm1. check-in: 63599fa5 user: mistachkin tags: trunk | |
| 17:43 | Add new PRAGMAs: "function_list", "module_list", and "pragma_list". All are enclosed within #ifdef SQLITE_INTROSPECTION_PRAGMAS. The compile-time option is not on ctime.c yet, since these are still experimental and one can always test "PRAGMA pragma_list" and see whether or not it returns an empty set. check-in: e0b6ae92 user: drh tags: trunk | |
| 17:33 | Add the "Pragma_list" pragma. Put all three pragmas created on this branch inside of #ifdef SQLITE_INTROSPECTION_PRAGMAS. Closed-Leaf check-in: 2f3c3781 user: drh tags: list-pragmas | |
| 16:46 | Improve clarity in the Win32 VFS for lsm1. check-in: 9c7a9e80 user: mistachkin tags: trunk | |
| 16:29 | Add support for LSM_DEBUG_MEM to the MSVC makefile for lsm1. check-in: 3340de83 user: mistachkin tags: trunk | |
| 16:27 | Remove a block from the Win32 VFS for lsm1 that is now superfluous. check-in: 5f726f28 user: dan tags: trunk | |
| 16:09 | In lsmtest, use an empty string instead of ":memory:" when requesting a temporary database from SQLite. This prevents other test code from trying to unlink() ":memory:", which fails on win32. check-in: 281ad505 user: dan tags: trunk | |
| 16:07 | Remove a block from the Win32 VFS for lsm1 that is now superfluous. check-in: db4a4140 user: mistachkin tags: trunk | |
| 16:06 | Memory reallocation fix for the Win32 VFS for lsm1. check-in: 5a3140e4 user: mistachkin tags: trunk | |
| 16:00 | Enhance the sqlite3VdbeMultiLoad() interface to automatically generate the OP_ResultRow opcode on PRAGMA implementations, for a small reduction in the library footprint. check-in: c46f0f07 user: drh tags: trunk | |
| 15:43 | Add new pragmas: "function_list" and "module_list" check-in: e5f01d7f user: drh tags: list-pragmas | |
| 13:59 | Exploit the fact that Expr.pRight and Expr.x are never used at the same time for a small performance gain. check-in: aacbb9a4 user: drh tags: trunk | |
| 12:58 | More efficient and compact implementation of walkExpr(). check-in: 115d4b83 user: drh tags: trunk | |
| 12:43 | More aggressive use of EP_Leaf on expression nodes, to help prune searches. check-in: c1a1d68c user: drh tags: trunk | |

| 22:43 | Small adjustment to main.mk that facilitates giving non-standard compile-time options to the shell. check-in: 7c7d53a9 user: drh tags: trunk | |
| 16:33 | Change the (machine-generated) keywordhash.h file to increase the scope of the tables used for keyword matching, so that the tables are accessible to functions other then keywordCode(). check-in: c5ed5ebd user: drh tags: trunk | |
| 13:51 | More compact implementation of the typeof() SQL function. check-in: efb4aab0 user: drh tags: trunk | |
| 13:23 | Avoid unnecessary upper-to-lower case conversion for function names when registering the built-in functions. check-in: 06269257 user: drh tags: trunk | |
| 03:06 | Small size reduction in findCollSeqEntry(). check-in: 55ecd303 user: drh tags: trunk | |
| 02:49 | Avoid unnecessary calls to sqlite3GetCollSeq() for a small performance gain. check-in: 503ba172 user: drh tags: trunk | |
| 01:28 | Slightly more compact implementation of the byte-code generator for the COMMIT and ROLLBACK commands. check-in: 4da663d9 user: drh tags: trunk | |

| 18:48 | Have fts3 virtual table cursors free internal resources when they reach EOF, instead of waiting until the xClose method is called. check-in: b6b14ab6 user: dan tags: trunk | |
| 14:29 | Fix a problem in lsmtest causing one test to fail for multi-threaded LSM connections. check-in: 2bce64c8 user: dan tags: trunk | |

| 19:23 | Fix further OOM handling cases in LSM. check-in: ca757c86 user: dan tags: trunk | |
| 17:25 | Fix a couple of problems in handling OOM conditions within LSM. check-in: 989a5c17 user: dan tags: trunk | |
| 12:50 | Fix a problem in the lempar.c Lemon template for YYSTACKDEPTH<=0 introduced by check-in [36e54cd8b1fb37] check-in: 268a40f4 user: drh tags: trunk | |

| 18:12 | Fix some minor typos in lsm1. check-in: 0ef777d7 user: mistachkin tags: trunk | |
| 11:44 | Avoid constantly freeing and reallocing small internal buffers associated with LSM cursors. Instead, allow them to persist for the lifetime of the cursor if they are LSM_SEGMENTPTR_FREE_THRESHOLD (default 1024) bytes or smaller. This change is based on research by Martijn Blaauw. check-in: bacfe8cb user: dan tags: trunk | |

| 13:35 | Compilation fix for lsm1 using MSVC. check-in: b7794cc5 user: mistachkin tags: trunk | |
| 13:19 | Add the LSM1 extension. check-in: 824e8327 user: drh tags: trunk | |
| 13:13 | Add the "stmts" virtual table to the amalgamation, activated when compiled using -DSQLITE_ENABLE_STMTSVTAB. Add the SQLITE_STMTSTATUS_REPREPARE and SQLITE_STMTSTATUS_RUN statistics outputs from sqlite3_stmt_status() and add corresponding columns to the stmts virtual table. Change the numeric value of SQLITE_STMTSTATUS_MEMUSED to get it out of the way of counter values. check-in: 88976ae3 user: drh tags: trunk | |
| 12:59 | The query planner examines the values of bound parameters to help determine if a partial index is usable. Reprepares may happen if the bindings change. This behavior is disabled by the QPSG setting. check-in: c322bfa2 user: drh tags: trunk | |
| 12:54 | Implement xUnlink, xShmMap, and xShmUnmap for lsm1 on Win32. Closed-Leaf check-in: 680cc064 user: mistachkin tags: lsm-vtab | |
| 12:49 | Add the SQLITE_STMTSTATUS_REPREPARE and SQLITE_STMTSTATUS_RUN options to sqlite3_stmt_status(). Use this for two new columns in the stmts virtual table. Closed-Leaf check-in: b0b0c8f8 user: drh tags: stmts-vtab | |
