| 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 | |
| 19:12 | Fix the memcpy calls in the lsmWin32OsShmMap function for lsm1. check-in: aa4890b9 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 | |

| 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 | |

| 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 | |

| 21:33 | In the command-line shell, add the -quote option to start up in quote mode. Enhance the ".mode" command so that it reports the current output mode if given no arguments. check-in: 5e3f9ea5 user: drh tags: trunk | |
| 21:11 | Remove the ".explain" command from the ".help" output of the command-line shell, though keep the implementation around for backwards compatibility. check-in: 7782c04e user: drh tags: trunk | |
| 20:31 | Some simple tests for the STMT virtual table. check-in: a26e17ee user: drh tags: trunk | |

| 17:27 | Edit comments in sqlite.h.in used for generating documentation, to improve the description of the new sqlite3_prepare_v3() interfaces, and other miscellaneous cleanup. No changes to executable code. check-in: 284707a7 user: drh tags: trunk | |
| 16:51 | More updates to the Win32 interface for lsm1. check-in: cae64769 user: mistachkin 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 | |

| 13:47 | In the lemon-generated parser, store the number of symbols on the RHS of each rule as a negative number and add it to the stack pointer, rather than storing the value as a positive and subtracting it. This makes the parser faster. check-in: b362f0d8 user: drh tags: trunk | |
| 11:56 | In the lemon-generated parser, automatically promote SHIFTREDUCE actions on nonterminal systems to pure REDUCE actions, for a performance enhancement. check-in: c46d94a8 user: drh tags: trunk | |
| 01:21 | Simplify error handling logic in sqlite3_exec() to save about 40 bytes. check-in: 6480916c user: drh tags: trunk | |
| 01:12 | Minor code simplification in the ALTER TABLE logic. check-in: bfc4e7f3 user: drh tags: trunk | |
