100 check-ins occurring around 90acdbfce9c08858.

2019-03-28
20:50
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)

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)
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

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)

22:34
Further enhancements and fixes. (check-in: c9f1972e user: mistachkin tags: msvcTcl)
16:52
Attempt to detect when the MSVC linker requires the /MACHINE argument. (check-in: 3e355846 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
Add an extra test for database corruption to defragmentPage(). (check-in: 80e951fc user: dan tags: trunk)
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
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)
16:03
Merge latest trunk changes into this branch. (check-in: 4cd20ca6 user: dan tags: reuse-schema)
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
20:48
Merge recent enhancements from trunk. (check-in: 000f4398 user: drh tags: apple-osx)
20:42

20:13
Fix a compiler warning in FTS5. (check-in: d5acf3af user: drh tags: trunk)

16:49
Add missing VdbeCoverage() macros to new code in window.c. (check-in: 4f9b93e6 user: dan tags: window-functions)
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)

10:30
Fix a typo in a comment. No changes to code. (check-in: c2f50aa4 user: drh tags: trunk)
2019-03-17
23:59
New hyperlink on the README.md file. (check-in: cc5ab967 user: drh tags: trunk)
23:44
Update the README.md file at the top level to talk about how to deal with version names and how to verify the code in Git mirrors. (check-in: e8c87a0a user: drh tags: trunk)
2019-03-16

20:46
Implement the EXCLUDE clause for window frames. (check-in: 9b43c3ee user: dan tags: window-functions)
