12:27
Add the pointer-type parameter to sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer(). The pointer type is a static string that must match (according to strcmp()) or else the pointer is passed as a NULL. This is a security measure to prevent crossing pointers between different extensions. check-in: e1196567 user: drh tags: branch-3.20

00:40
Add an experimental "pointer type" parameter to sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer(). The pointer type is a string that must compare equal using strcmp() or else the pointer comes through as a NULL. check-in: 211cce04 user: drh tags: pointer-types
2017-07-15
20:48

15:32
Update the Makefile for LSM1 so that the LSMOPTS can be set prior to including the Makefile, in order to add platform arguments such as -fPIC. check-in: fe319bcd user: drh tags: trunk
15:18
Fix a typo in the header comment to the remember extension. No code changes. check-in: 604b9664 user: drh tags: trunk
15:14
Change the name of the STMT virtual table to SQLITE_STMT. Also remove the first column of that virtual table, which was a pointer leak. check-in: 1bc4e934 user: drh tags: trunk

18:09
Add new interfaces sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer() used to safely move pointer values through SQL without exposing underlying memory address information. check-in: 72de49f2 user: drh tags: trunk
17:56
Fix an incorrect type signature for the loadable extension pointer for sqlite3_result_pointer(). Closed-Leaf check-in: 0bd7875b user: drh tags: bind-pointer
17:54
Add the three new pointer interfaces to the loadable extension mechanism. Update sqlite3_value_subtype() documentation to remove the statement about it not being used internally. check-in: e5a51803 user: drh tags: bind-pointer
17:48
Update the FTS3 extension to use sqlite3_result_pointer() and sqlite3_value_pointer() for passing FTS3 cursor objects from the table into functions such as snippet(). check-in: 0fa2e170 user: drh tags: bind-pointer
17:34

Compile cleanly with SQLITE_OMIT_UTF16. check-in: 783100b8 user: drh tags: trunk
2017-07-11
20:36
In lsm, attempt to unmap the database file before truncating it when disconnecting. A mapped file may not be truncated on win32. check-in: 39069941 user: dan tags: trunk
19:55
Simplify the way in which the database file is truncated when the last connection disconnects. Also ignore the error code from the xTruncate call - as truncating a database file is always optional. check-in: b0a49d90 user: dan tags: trunk
18:11
Fix harmless compiler warnings in the core. check-in: 55e93f25 user: drh tags: trunk

13:34
Change the src/shell.c file so that it is generated from a new script at tool/mkshellc.tcl and the template file src/shell.c.in, and automatically includes the extensions it needs out of ext/misc. check-in: 17e0bb12 user: drh tags: trunk
02:53
Fix a backup2 test case so that it works on FreeBSD. check-in: 724819b4 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
2017-07-10
21:32
Fix harmless compiler warnings in lsmtest. check-in: bd8a1fb9 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

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
18:27
Disable compiler intrinsics when using the Intel C Compiler. Leaf check-in: dbb59f61 user: drh tags: icc-fix
2017-07-07

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

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
