Prevent aliases of window functions expressions from being used as arguments to aggregate or other window functions. check-in: 1e16d3e8 user: dan tags: trunk
13:53
Show the pointer address for Window objects in the TreeView display. check-in: 1ae70ad2 user: drh tags: trunk
13:35
More improvements to TreeView output for Window objects: (1) Show when the frame-spec is implied rather than explicit. (2) Move the FILTER clause out from within the OVER clause, making it a sibling of the OVER clause, to match syntax. check-in: d6a07433 user: drh tags: trunk
13:03
Improved TreeView display of Window objects. Change the Window.eType field to Window.eFrmType to avoid confusion with other "eType" values. check-in: ec2f207d user: drh tags: trunk
04:03
If the string formatter in sqlite3NestedParse() fails due to an over-length string, make sure this error is recorded by the parser so that it knows to fail. check-in: 85e53ff1 user: drh tags: trunk
01:00
Improvements to the README.md file. No code changes. check-in: bbdbaf84 user: drh tags: trunk
2019-03-27
14:59
Support building the Tcl bindings DLL using MSVC. check-in: b2011c13 user: mistachkin tags: trunk
14:58
Fix harmless compiler warnings seen with MSVC. check-in: 5be64ea8 user: mistachkin tags: trunk
2019-03-26
16:47
Fix a problem with window frames that use "BETWEEN <start> AND 0 PRECEDING". check-in: 7927b6b0 user: dan tags: trunk
16:21
Fix harmless compiler warnings. check-in: a063f7c4 user: drh tags: trunk

2019-03-25
22:05
Fix an obsolete comment in the CLI. No code changes. check-in: fade103c user: drh tags: trunk
21:56
In the CLI, code the "sqlite_parameters" name directly rather than using a macro, for clarity of presentation for users who are reading the code for the purpose of seeing how the CLI implements parameter binding. check-in: e775ef00 user: drh tags: trunk
21:55
Remove a test from the index build logic which is no longer needed and is in fact unreachable. check-in: 9b20ee10 user: drh tags: trunk
21:35
Change the name of the parameter table in the CLI to "sqlite_parameters". Doing so involves adding SQLITE_DBCONFIG_WRITABLE_SCHEMA and allowing the creation of tables whose names begin with "sqlite_" and that are indexed while writable_schema is on. check-in: 24ef3844 user: drh tags: trunk
19:50
Earlier detection of corruption while added to the freelist. check-in: 8c80b004 user: drh tags: trunk

15:09
Improvements to the help text in the CLI. check-in: 919fec91 user: drh tags: trunk
15:06
Fix the writefile() SQL function implemented by ext/misc/fileio.c such that any directories created have standard umask permissions, not permissions of the file that is to be written. check-in: f11c8959 user: drh tags: trunk
14:24
For the ".archive --update" command in the CLI, only update files if their mtime or mode has changed. To force an update, use the new --insert instead. check-in: 191a023a user: drh tags: trunk

13:53
We learn that readdir_r() is deprecated in favor of plain old readdir(), which is now suppose to be threadsafe using thread-local storage. So remove the use of readdir_r() from the test code. (SQLite itself never calls readdir() or readdir_r()). check-in: 7a0a26ed user: drh tags: trunk
11:38
Add the --limit N option to dbfuzz2. Set the default callback limit to 250K. check-in: b99f8512 user: drh tags: trunk

13:51
Remove assert() statements based on the counter-factual proposition that 0 is not a valid cursor number. check-in: c7b33618 user: dan tags: window-functions
2019-03-20
18:22

05:45
Fix various harmless compiler warnings seen with MSVC. Closed-Leaf check-in: 1c0fe5b5 user: mistachkin tags: noWarnings

15:36
When computing the amount of scratch memory needed during a rebalance operation, assume the worst case for the number of cells per page, rather than relying on the BtPage.nCell value, which might be incorrect for a corrupt database. check-in: a420ebd0 user: drh tags: trunk
11:56
