2019-03-26
16:21
Fix harmless compiler warnings. check-in: a063f7c4 user: drh tags: trunk
14:04
Use the mutex-free PRNG in this branch, since anybody using this branch is probably interested in high concurrency. check-in: e88fc6d0 user: drh tags: begin-concurrent
13:28
Bring this branch into closer alignment with begin-concurrent. check-in: 6433d366 user: drh tags: begin-concurrent-pnu
13:08
Add support for new window functions related features - GROUPS frames, RANGE frames with logical start and end points, the EXCLUDE clause and window chaining. check-in: c6da3911 user: dan tags: trunk
12:37
Merge recent enhancements from trunk. check-in: dc3c0b8b user: drh tags: apple-osx
12:29
Bring this branch up to date with all the latest enhancements. check-in: 2e964aaf user: drh tags: begin-concurrent-pnu-wal2
12:22
Merge enhancements from trunk. check-in: a0e2e902 user: drh tags: wal2
12:16
Merge the latest trunk changes. check-in: 51e3e835 user: drh tags: begin-concurrent-pnu
12:07
Merge recent enhancements from trunk. check-in: 774d0d52 user: drh tags: begin-concurrent
11:57
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

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
2019-03-23
00:38
Support Tcl libraries with a suffix. Closed-Leaf check-in: 8d015399 user: mistachkin tags: msvcTcl
2019-03-22
22:34
Further enhancements and fixes. check-in: c9f1972e user: mistachkin tags: msvcTcl

13:56
Fix a problem with a window function in a correlated sub-query where at least one reference to the outer SELECT appears in a FROM clause sub-select. Closed-Leaf check-in: 9aca86f9 user: dan tags: window-functions
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
01:26
Sync up the autoconf makefile for MSVC. check-in: ecbae90a user: mistachkin tags: msvcTcl
01:25
Support building the Tcl bindings DLL using MSVC. check-in: 908c4c89 user: mistachkin tags: msvcTcl
2019-03-21
21:18

17:22
Merge latest trunk changes with this branch. check-in: 3196f5f4 user: dan tags: reuse-schema
17:13
Disable the feature on this branch in non-SQLITE_ENABLE_SHARED_SCHEMA builds. check-in: b8e53608 user: dan tags: reuse-schema
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
20:27
Experimental change to apply affinity before running CHECK constraints on an INSERT. Note that in the CHECK constraints, REAL affinity really is REAL affinity, and not numeric affinity. This causes failures in some tests that are assuming affinity is applied after CHECK constraints. Leaf check-in: 9ef69d18 user: drh tags: apply-affinity-first
20:02
Use the IsReuseSchema() macro more consistently. Also, rename it to IsSharedSchema(). check-in: c1be211c user: dan tags: reuse-schema
19:17
Fix an error message. check-in: a70fdaa3 user: dan tags: reuse-schema
18:22

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
16:03
Merge latest trunk changes into this branch. check-in: 4cd20ca6 user: dan tags: reuse-schema

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
20:48
Merge recent enhancements from trunk. check-in: 000f4398 user: drh tags: apple-osx
20:42

20:13

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
Revert the OP_MustBeInt opcode implementation on this branch so that it again matches trunk. The extra functionality is no longer required. check-in: c02f77b1 user: dan tags: window-functions
11:35
Tweak the tool/cg_anno.tcl script so that it can run on systems without /usr/bin/tclsh. check-in: a026189a user: dan tags: trunk
11:17
Update this branch with latest trunk changes. check-in: 98cc2659 user: dan tags: window-functions
09:57
