Remove some stale references to the addopcodes.tcl script from documentation. (check-in: c0381b0b user: drh tags: trunk)
20:56
Eliminate the tool/addopcodes.tcl script. The purpose of that script was to keep the number of parser codes below 256 in order to save parser table space. But we have long since blown through that ceiling so the addopcodes.tcl script was just needless complexity. There is no longer any reason to keep it around. (check-in: d2728192 user: drh tags: trunk)
20:47
Add further tests so that veryquick.test covers all vdbe branches. (check-in: cbc67de5 user: dan tags: trunk)

16:38
Add the ability to override the new corruption detection logic of the previous checkin, in order to exercise downstream corruption detection during testing. (check-in: e859d318 user: drh tags: trunk)
15:44
In the xfer-optimization, do early detection of when the source and destination index share the same btree, to avoid a long delay prior to reporting the database corruption. (check-in: af1e5873 user: drh tags: trunk)
2019-04-04
22:05

Correctly initialize the loadable extension thunk. (check-in: 4fca46de user: drh tags: trunk)
15:25
Simplification of the recent VACUUM changes that make the code more like what it was before the change. Also, make the VACUUM command a no-inline procedure to work around a performance regression. (check-in: 9cac5ac1 user: drh tags: trunk)
14:36
Fix an incorrect comment on a test case for rowid renumbering in VACUUM. (check-in: 0d293fb4 user: drh tags: trunk)
14:00
Only preserve rowid values for VACUUM INTO. Keep the legacy behavior of renumbering rowids for ordinary VACUUM. (check-in: 13a0ea64 user: drh tags: trunk)
2019-04-03
17:48
Add a defense-in-depth NEVER() test to the WAL cleanup code. (check-in: 8d3af201 user: drh tags: trunk)
16:27

2019-04-02
18:12
Small optimizations to the grammar for window functions save about 120 bytes of space in the parser tables. (check-in: bce01d95 user: drh tags: trunk)
17:45
Use a separate bit on db->dbOptFlags to disable the xInverse optimization on window functions, rather than reusing the query-flattener disable bit. (check-in: bc0fb1c3 user: drh tags: trunk)
17:45
Including the phrase EXCLUDE NO OTHERS in the frame-spec of a window function (which is the default setting for EXCLUDE) silently disables the xInverse optimization. This is a feature, but we will keep it undocumented for now in case we later decide it is a bad idea. (check-in: 10aedce3 user: drh tags: trunk)
13:10
Put the list of keywords in mkkeywordhash.c into alphabetical order. (check-in: ac98b23b user: drh tags: trunk)
01:00
Merge fixes from trunk. (check-in: 20372906 user: drh tags: apple-osx)
00:56
Make sure the MEM_FromBind bit inthe Mem.flags field is not included in the MEM_TypeMask. This critical changes was omitted from the previous two check-ins by mistake, and so those check-ins are not fully functional. (check-in: f7ba2daf user: drh tags: trunk)
00:48
Add new APIs to the extension loading mechanism. (check-in: 6f122faf user: drh tags: trunk)
00:34
Merge enhancements from trunk. (check-in: 0b35aebb user: drh tags: apple-osx)

2019-03-29
17:26
Change the fts3_tokenizer() function to always return the pointer as a BLOB as long as the first argument is a bound parameter, regardless of the SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER setting. (check-in: 27160df7 user: drh tags: value_frombind)
11:39
The two-argument version of fts3_tokenizer() works regardless of the value of SQLITE_DBCONFIG_ENABLE_FT3_TOKENIZER as long as the second argument is a bind parameter. (check-in: ab76e3a9 user: drh tags: value_frombind)
11:13
Initial implementation of the sqlite3_value_frombind() interface. (check-in: 98da62df user: drh tags: value_frombind)
01:15

Add new test cases to test/fuzzdata8.db (check-in: f908cd40 user: drh tags: trunk)
16:15
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)

2019-03-25
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)
18:44
Fix a faulty assert() statement in balance_nonroot() - the assert() should use get2byteNotZero() instead of get2byte() for the corner case where the number cells is zero on a 65536-byte page. (check-in: bcbe7d96 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

In the CLI, give better error messages if something goes wrong with the ".dbinfo" command. (check-in: 3649a77b user: drh tags: trunk)
16:58
Fix a potential dangling pointer deference in an ALTER TABLE run on a schema that contains constructs of the form "PRIMARY KEY(column COLLATE collation)". (check-in: b9e2393c user: dan tags: trunk)
12:08
Fix harmless compiler warnings from MSVC. (check-in: f0f02d46 user: drh tags: trunk)
11:16
Enhance the rtreenode() function of rtree (used for testing) so that it uses the newer sqlite3_str object for better performance and improved error reporting. Test cases added to TH3. (check-in: 90acdbfc user: drh tags: trunk)
05:45
Fix various harmless compiler warnings seen with MSVC. (Closed-Leaf check-in: 1c0fe5b5 user: mistachkin tags: noWarnings)
2019-03-19
