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
2017-07-09
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
22:30
Add the --icc, --gcc7, and --orm options to the speed-check.sh test script. check-in: 70dae08a user: drh tags: trunk
20:46
Support read-only MVCC transactions in server-mode. Started using "BEGIN READONLY". check-in: 5a043aa8 user: dan tags: server-process-edition
18:27
Disable compiler intrinsics when using the Intel C Compiler. Leaf check-in: dbb59f61 user: drh tags: icc-fix

22:58
Merge in all the latest trunk enhancements. check-in: 7f48f6ab user: drh tags: apple-osx
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

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

15:43
Add new pragmas: "function_list" and "module_list" check-in: e5f01d7f user: drh tags: list-pragmas
14:54
Fix an obsolete comment on the sqlite3_namelist() function implementation. Closed-Leaf check-in: f4229857 user: drh tags: experimental-namelist
14:26
Merge recent enhancements from trunk. check-in: 73d0fc02 user: drh tags: bind-pointer
13:59

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
11:49
Very slightly smaller and faster sqlite3WalkSelect(). check-in: 9bc65635 user: drh tags: trunk
2017-07-06
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
22:40
Always load the schema before starting tab-completion. check-in: 907fd3aa user: drh tags: experimental-namelist
20:08
Tab-completion now also works using readline/editline. check-in: c906739f user: drh tags: experimental-namelist

17:36
Initial implementation of a highly experimental interface for listing all keywords and symbolic names for an SQLite database connection. check-in: 04ef6783 user: drh tags: experimental-namelist
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

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
2017-06-29

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

19:08
Fix issues in the POSIX and Win32 interfaces for lsm1. check-in: 38ec4141 user: mistachkin 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

Further corrections to the Win32 interface for lsm1. check-in: 4df6e247 user: mistachkin 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
12:49
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

15:56
Incorporate recent trunk changes. Closed-Leaf check-in: 62b8269b user: drh tags: prepare_v3

15:17
Fix harmless compiler warnings in the CSV extension. check-in: f02a5459 user: drh tags: trunk
