100 check-ins occurring around 8af0caeb6d1e55f6.

2019-04-10
12:02
Change the name of some internal testing interfaces to avoid a name conflict in AIX. check-in: c1cae7e7 user: drh tags: trunk
00:58
Do not place arbitrary restrictions on the length of the failure message for a uniqueness constraint. check-in: 037da798 user: drh tags: trunk

21:37
New test case for SQLITE_TOOBIG errors. check-in: 4c77fbbe user: drh tags: trunk

21:17
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

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
Add the vtab enable/disable options to the sqlite3_db_config TCL command in the testfixture. Leaf check-in: c7052428 user: drh tags: disable-vtab
21:40

18:20
Minor fixes to requirements marks. check-in: 02ebc60b user: drh tags: trunk
17:58
Add test cases to improve coverage of VDBE branches. Still some to go. check-in: 4cef609d user: dan tags: trunk
17:39
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
17:54
Add a defense-in-depth NEVER() test to the WAL cleanup code. Leaf check-in: 1109942a user: drh tags: branch-3.27
17:48

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

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

17:24

16:23
Frame range comparisons can never be NULL because the values will have been checked for NULL prior to the test. check-in: fa37cf9a user: drh tags: trunk
15:55
Mark rowid-comparison opcodes as never-null for VDBE coverage tracking purposes. check-in: a69bb4f2 user: drh tags: trunk

Early detection of too many columns in an index avoid a possible 16-bit signed integer overflow. check-in: 8af0caeb user: drh tags: trunk
18:17
Add some missing VdbeCoverage() macros. check-in: d03b6113 user: drh tags: trunk
2019-03-30

19:17
Add a call to sqlite3FaultSim(410) inside of btreeRestoreCursorPosition() to simplify testing of error scenarios. check-in: bb643bac user: drh tags: trunk
18:39
The defragmentPage() routine detects corruption in the first-free-slot fields at offset 1 in the header and throws an error, rather than asserting. check-in: fb125bd3 user: drh tags: trunk
17:30
Add the blobio.c extension module implementing readblob() and writeblob(). Experimental. check-in: e3fde56d user: drh tags: trunk
17:07
Add an extra IO-error test to windowfault.test. check-in: 5b8c44cd user: dan tags: trunk
2019-03-29
17:26

15:21
Remove the unused P5 flag from the OP_Rewind opcode. check-in: c2edbf3b user: drh tags: trunk

11:48
Fix typos in the comments of the sessions extension, one of which affects the generated documentation. No code changes. check-in: 040d5d51 user: drh tags: trunk
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

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

Merge recent trunk enhancements. check-in: db4e2cc3 user: drh tags: reuse-schema
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

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
