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)
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)
2017-07-07
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)
19:12
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)

16:27
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)

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)
19:26
Use the sqlite3_namelist() interface to implement simple tab-completion using linenoise. (check-in: 5cc7b0e2 user: drh tags: experimental-namelist)
18:52
Change the sqlite3_namelist() interface to return a pointer to an array of pointers to strings, and to avoid duplicates. (check-in: 70291110 user: drh tags: experimental-namelist)
18:25
The sqlite3_namelist() routine now works for all name types. (check-in: e41d6217 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)

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
21:33
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)

18:14
Omit a test of codepoint 0x202F (non-break narrow space) from the fts3 ICU tests. Different versions of ICU apparently handle this obscure codepoint slightly differently. (check-in: 69ae6889 user: dan tags: trunk)

Version 3.19.2 (check-in: edb4e819 user: drh tags: release, branch-3.19, version-3.19.2)
11:39
The SQLITE_EXTRA_IFNULLROW compile-time option causes OP_IfNullRow opcodes to be issued for references to the right-hand side table of *any* flattened join, not just LEFT JOINs. This puts extra stress on the OP_IfNUllRow opcodes for testing purposes. (check-in: 1a074c8a user: drh tags: branch-3.19)
00:28
The TK_IF_NULL_ROW expression node must be treated as a variable that references the table Expr.iTable. Proposed fix for ticket [7fde638e94287d2c]. (check-in: b30a364a user: drh tags: branch-3.19)
00:12
Increase the version number to 3.19.2 since ticket [7fde638e94287d2] is going to necessitate another patch release. (check-in: c315727a user: drh tags: branch-3.19)

Remove a surplus semicolon, which was harmless on gcc and clang but caused compile-time errors on msvc. This only comes up using the encryption extension. (check-in: 4510d55d user: drh tags: branch-3.19)
01:29
When flattening a query, make sure iTable attribute of TK_IF_NULL_ROW operators (that result from a prior flattening of a LEFT JOIN) are updated correctly. Fix for ticket [cad1ab4cb7b0fc344]. (check-in: 919d36e6 user: drh tags: branch-3.19)

Fix a case where NULL was being passed to memcmp() following an OOM. This is probably not a real problem, as the number-of-bytes parameter was passed 0 in this case, but it was causing a santizer complaint. (check-in: 3ea2bad2 user: dan tags: trunk)
00:45
When planning a query using sorting, resolve ties in the solver by selecting loop plans with the smaller unsorted cost. (check-in: f261678c user: drh tags: trunk)
