2018-06-02
16:32
Work around a sanitizer warning about a pointer being only 4-byte aligned instead of 8-byte aligned. Closed-Leaf check-in: 1b807b51cd user: drh tags: align8-fix
14:37
Proposed fix for the use of posix_fallocate() so that it handles EINVAL returns correctly. Closed-Leaf check-in: ab3a5539db user: drh tags: einval-from-fallocate
12:05
Fix the CSV extension so that it works with single-column CSV files. check-in: e336cf0048 user: drh tags: trunk
11:31
Ensure that sqlite3AuthRead() is only call for TK_COLUMN and TK_TRIGGER expression nodes. This fixes a harmless assert() identified by OSSFuzz. Move the assert() into a position where it is tested even if the authorizer is disabled. check-in: d0c3beef7c user: drh tags: trunk
2018-06-01
21:00
Allow an entire partition to be cached in a temp table for all types of window frames. This is required by nth_value() and others. check-in: b5b18f6613 user: dan tags: exp-window-functions
13:30
Fix a bug in the SQLITE_ENABLE_SORTER_REFERENCES code causing an out-of-bounds array reference. check-in: 8cadaf587d user: dan tags: trunk
2018-05-31
19:14
More documentation typo fixes. No code changes. check-in: 66c24513c2 user: drh tags: trunk
19:00
Fix a harmless typo in a comment used to generate documentation. check-in: 5a2a88cb01 user: drh tags: trunk
2018-05-30

Allow min() and max() to be used as window functions. check-in: c16125a884 user: dan tags: exp-window-functions

Add the Makefile.fallback makefile to the amalgamation tarball. check-in: ce3d045633 user: drh tags: trunk
07:36
Do not use the codec on the resetdb.test script. check-in: fe55cea0c8 user: drh tags: trunk

00:59
Fix a harmless compiler warning. check-in: 8d02c7a6a0 user: drh tags: trunk
00:54
Demonstration code on a possible technique for optimizing the use of IN operator on columns to the right of multicolumn indexes. If the OP_Noop generated where were really a new opcode that checked to see if there existed any entries in the index with a matching prefix, it might prevent unnecessary iterations of the IN operator. check-in: 92f0fe155d user: drh tags: multikey-opt-idea
2018-05-29
19:12
Increase the number of database handles opened by test script oserror.test to provoke an "out of file-descriptors" error to 20000 (from 2000). check-in: 3b00f73456 user: dan tags: trunk
17:17

15:18
Add a comment to justify a goto statement. No code changes. check-in: f141d80647 user: drh tags: trunk
14:29
More minor changes to test scripts. check-in: ce9b756f09 user: dan tags: trunk

2018-05-28
23:59
The geopoly virtual table seems to be working. But only thinly tested so far. check-in: 4288f1ad59 user: drh tags: rtree-geopoly
18:30
Further window frame tests and fixes. check-in: e74c6e9185 user: dan tags: exp-window-functions
18:29
Do not require a statement journal in cases where REPLACE conflict handling is used to insert a single row, so long as the REPLACE operation cannot fire any triggers or foreign key actions. check-in: 469a62ca33 user: dan tags: trunk
18:25
When compiling with SQLITE_DEBUG, add run-time checks to ensure that no statement aborts unless either there have been no writes or else there is a statement journal. check-in: ce99c77244 user: drh tags: trunk
17:43
Fix the build so that it works with -DSQLITE_TEST_REALLOC_STRESS Closed-Leaf check-in: 90ba2b2e5c user: drh tags: stmt-journal-testing
17:31
When compiling with SQLITE_DEBUG, add run-time checks to ensure that no statement aborts unless either there have been no writes or else there is a statement journal. check-in: 5a4542dbcf user: drh tags: stmt-journal-testing
13:23
Untested incremental check-in. Add the geopoly_xform() function. Complete basic logic for the geopoly virtual table. check-in: ed06cc3256 user: drh tags: rtree-geopoly
2018-05-26
21:17
More fixes for different window frame types. check-in: 2c85668a0f user: dan tags: exp-window-functions
20:04
Merge the ability to plan virtual table queries using overloaded functions. check-in: 2c2a202c14 user: drh tags: rtree-geopoly
18:03
Experimental change that allows overloaded functions to be analyzed by the xBestIndex method and used by the xFilter method of a virtual table. Leaf check-in: a353b1d7ee user: drh tags: vtab-func-constraint
16:00
Store application-defined function names as lower-case to avoid the need for case conversions before calling xFindFunction on virtual tables. Avoid using lookaside to store the destructors for application defined functions, as lookaside should be reserved for transient allocations. check-in: 777189ce88 user: drh tags: trunk
13:55
Add a single sentence of documentation about the virtual table scan flags. No changes to code. check-in: 27b4fa5dd0 user: drh tags: trunk

2018-05-25

20:53
Incremental check-in: Progress toward implementing the geopoly vtab. check-in: 9b7d6f986a user: drh tags: rtree-geopoly
20:30
Fix "RANGE BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING" window frame processing. check-in: b4e9c68669 user: dan tags: exp-window-functions
19:22
Forward port the geopoly extension functions into the r-tree extension, with the idea of creating a new spatial index based on simply polygons. check-in: 0593aac88a user: drh tags: rtree-geopoly
14:39
This is an untested proof-of-concept for enhancements to RTree that attempt to use sqlite3_value_nochange() to reduce the amount of work associated with UPDATE operations in cases where either the coordinates or the auxiliary data is unchanged. Leaf check-in: 6f7cfeff70 user: drh tags: rtree-update-optimization
09:36
Merge latest trunk changes into this branch. check-in: 6232519899 user: dan tags: exp-window-functions
09:29

03:46
Add SQLITE_LOCKED_VTAB and SQLITE_CORRUPT_SEQUENCE to sqlite3ErrName(). Also, use SQLITE_CORRUPT_BKPT in one more place. Leaf check-in: eac8888db3 user: mistachkin tags: errCodes
2018-05-24
23:51
When doing a one-pass UPDATE or DELETE on virtual tables, close the cursor prior to running VUpdate. This allows one-pass to work on virtual tables that do not allow concurrent reads and writes. Enhance rtree to take advantage of this new capability. check-in: b816023ce0 user: drh tags: trunk
22:42
New test case for reading and writing the same rtree concurrently. check-in: 3ba08e53d5 user: drh tags: trunk
22:31
Do not allow RTree writes when a read cursor is active on the same virtual table, as the writes might rebalance and disrupt the read cursors. Return the new SQLITE_LOCKED_VTAB error code if this happens. check-in: d4ce666108 user: drh tags: trunk
21:10
Allow "<expr> PRECEDING" to be used to specify the end of a window frame. check-in: 7b709a989c user: dan tags: exp-window-functions
17:49
Support other frame types that use "<expr> PRECEDING" or "<expr> FOLLOWING" as start or end conditions. check-in: ec7b648c7f user: dan tags: exp-window-functions
17:38
In the OOM testing logic, add the sqlite3FirstFault() routine as a place to set a breakpoint the first time any simulated OOM fault occurs for a single test case. check-in: b4d80bd287 user: drh tags: trunk
17:25
Fix a typo in a comment used to generate VDBE opcode documentation. No code changes. check-in: 36cdfbf2ce user: drh tags: trunk
