2018-06-08
11:45
Fixes to allow group_concat() to be used as a window function. (check-in: 89bbc9ba user: dan tags: exp-window-functions)
2018-06-07
20:35
Merge latest trunk changes with this branch. (check-in: 25102203 user: dan tags: exp-window-functions)
20:08
Add window functions lag() and lead(). (check-in: ef342070 user: dan tags: exp-window-functions)
18:13
The IN-early-out optimization: When doing a look-up on a multi-column index and an IN operator is used on a column other than the left-most column, then if no rows match against the first IN value, check to make sure there exist rows that match the columns to the right before continuing with the next IN value. (check-in: 09fffbdf user: drh tags: trunk)
18:01
Fix the assert()s in the byte-code engine that prove that cursors are unidirectional. (Closed-Leaf check-in: 4b0b4e14 user: drh tags: multikey-opt-idea)
17:45
Add support for window function first_value(). (check-in: 060b2640 user: dan tags: exp-window-functions)
17:32
Remove the NextIfOpen and PrevIfOpen opcodes which are no longer needed when the IN-early-out optimization is working. (check-in: 439c8162 user: drh tags: multikey-opt-idea)
16:07
Test cases. (check-in: 085e8637 user: drh tags: multikey-opt-idea)
15:54
Fix problems with the nth_value() function. (check-in: 63002b9a user: dan tags: exp-window-functions)
15:28
Merge the ".stat/.eqp" CLI fix from trunk. (check-in: a91cad33 user: drh tags: multikey-opt-idea)
15:23
Avoid using a prepared statement for ".stats on" after it has been closed by the ".eqp full" logic. Fix for ticket [7be932dfa60a8a6b3b26bcf76]. (check-in: bb87c054 user: drh tags: trunk)
14:59
Add the WHERE_IN_EARLYOUT flag and use it to clarify the logic of this optimization. (check-in: 522f1eac user: drh tags: multikey-opt-idea)
14:32
Merge recent trunk enhancements. (check-in: e9d7bf4f user: drh tags: multikey-opt-idea)
2018-06-06
23:31
Change a comma into a logically equivalent but semantically clearer semicolon. (check-in: 71f97f0f user: drh tags: trunk)
20:55
More space and performance enhancements to sqlite3VdbeRecordCompare(). (check-in: 83a60ff0 user: drh tags: trunk)
20:51
Add implementation of nth_value() window function. (check-in: eb1fb420 user: dan tags: exp-window-functions)
20:29
Small performance optimization in sqlite3VdbeRecordCompareWithSkip() for the common case where the comparison is equal. (check-in: 1e616e25 user: drh tags: trunk)
19:48
Rearrange the order of some checks in the integrity_check pragma for a very slight performance gain. (check-in: 4b853f02 user: drh tags: trunk)
18:50
Fix the sqlite3BeginTrans() calls within the snapshot extension. (check-in: 1fef7ad2 user: drh tags: trunk)
17:45
Another minor optimization to OP_Transaction. (check-in: d80077ae user: drh tags: trunk)
17:12
Merge the 3.24.0 changes plus a few subsequent enhancements. (check-in: be7004a9 user: drh tags: begin-concurrent-pnu)
17:03
Merge changes from trunk, including all the 3.24.0 changes plus some later enhancements. (check-in: d7299bfe user: drh tags: begin-concurrent)
16:28
Change sqlite3BtreeBeginTrans() to return the BTREE_SCHEMA_COOKIE, for a small speed improvement when starting new transactions. (check-in: a10662aa user: drh tags: trunk)
01:18
Fix the ".archive" command in the CLI (and the corresponding -A command-line option) so that it silently ignores filenames that contain "../" in their names. This prevents the "Zip Slip" attack. (check-in: 27291f2d user: drh tags: trunk)
00:36
Attempt to optimize the resolveExprStep() routine by mapping Expr opcodes into a subset of opcodes that resolveExprStep() cares about and only calling the routine when those opcodes are encountered. Is slightly faster, but it seems like the very slight performance bump is not worth the added complexity. Saved on a dead-end branch for historical reference. (Closed-Leaf check-in: bad4d7a0 user: drh tags: dead-end)
2018-06-05
23:51
Update the version number to 3.25.0 for the next development cycle. (check-in: 7598236c user: drh tags: trunk)
23:21
Avoid unnecessary loads of columns in an aggregate query that are not within an aggregate function and that are not part of the GROUP BY clause. (check-in: e15e1006 user: drh tags: trunk)
20:45
Add the OP_IfNoHope and OP_SeekHit opcodes used to reduce the number of unnecessary sqlite3BtreeMovetoUnpacked() calls when checking for an early exit on IN-operator loops. Futher optimizations are likely possible here. (check-in: 6bf251af user: drh tags: multikey-opt-idea)
20:04
Calculate non-aggregate expressions in the SELECT list of an aggregate query that does not use min() or max() once per group, instead of once per row visited. (Closed-Leaf check-in: dce2dfbe user: dan tags: exp-agg-opt)
16:16
Add implementation of last_value() window function. (check-in: 2493ce1a user: dan tags: exp-window-functions)
15:16
Use an OP_NotFound opcode to cancel futile IN operators early. The current implementation is suboptimal because it always runs teh OP_NotFound. This still needs to be enhanced to only do the OP_NotFound if no results have been seen on the current loop. (check-in: 87a9fc50 user: drh tags: multikey-opt-idea)
13:54
Merge trunk changes. (check-in: 047295c5 user: drh tags: multikey-opt-idea)
13:43
Update and correct the documentation on the OP_OpenRead, OP_OpenWrite, and OP_ReopenIdx opcodes. No code changes other than the addition of an assert(). (check-in: 8a0b730d user: drh tags: trunk)
2018-06-04
19:24
Version 3.24.0 (check-in: c7ee0833 user: drh tags: trunk, release, version-3.24.0)

2018-06-02
21:04
Add support for window functions row_number(), rank(), dense_rank() and percent_rank(). (check-in: 91c1cb7a user: dan tags: exp-window-functions)
19:14
Avoid using a misaligned pointer. (check-in: 1ecb3aa1 user: drh tags: trunk)
19:01
Fix the usage of posix_fallocate() so that it correctly responds to EINVAL returns. (check-in: ce2c3e7a user: drh tags: trunk)
17:00
Update a test case in malloc5.test to take into account that malloc() sometimes returns slightly more space than requested. (check-in: 3d5eae1c user: dan tags: trunk)
16:32
Work around a sanitizer warning about a pointer being only 4-byte aligned instead of 8-byte aligned. (Closed-Leaf check-in: 1b807b51 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: ab3a5539 user: drh tags: einval-from-fallocate)
12:05
Fix the CSV extension so that it works with single-column CSV files. (check-in: e336cf00 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: d0c3beef 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: b5b18f66 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: 8cadaf58 user: dan tags: trunk)
2018-05-31

00:59
Fix a harmless compiler warning. (check-in: 8d02c7a6 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: 92f0fe15 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: 3b00f734 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: 4288f1ad user: drh tags: rtree-geopoly)
18:30
Further window frame tests and fixes. (check-in: e74c6e91 user: dan tags: exp-window-functions)
18:29

2018-05-26
21:17
More fixes for different window frame types. (check-in: 2c85668a user: dan tags: exp-window-functions)
20:04
Merge the ability to plan virtual table queries using overloaded functions. (check-in: 2c2a202c 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: a353b1d7 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: 777189ce user: drh tags: trunk)
13:55
Add a single sentence of documentation about the virtual table scan flags. No changes to code. (check-in: 27b4fa5d user: drh tags: trunk)

20:30
Fix "RANGE BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING" window frame processing. (check-in: b4e9c686 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: 0593aac8 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: 6f7cfeff user: drh tags: rtree-update-optimization)

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: b816023c user: drh tags: trunk)
22:42
New test case for reading and writing the same rtree concurrently. (check-in: 3ba08e53 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: d4ce6661 user: drh tags: trunk)
21:10
Allow "<expr> PRECEDING" to be used to specify the end of a window frame. (check-in: 7b709a98 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: ec7b648c 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: b4d80bd2 user: drh tags: trunk)
17:25
Fix a typo in a comment used to generate VDBE opcode documentation. No code changes. (check-in: 36cdfbf2 user: drh tags: trunk)

17:53
Remove a branch that is no longer used due to the fix to the sqlite_sequence schema problem, ticket [d8dc2b3a58cd5dc2918a1d4acbba4676a23ada4c] (check-in: 06674269 user: drh tags: trunk)
16:50
Verify that the sqlite_sequence table exists and is in approximately the correct format prior to using it to process an autoincrement table. Fix for ticket [d8dc2b3a58cd5dc2918a1d4a]. (check-in: e199e859 user: drh tags: trunk)

15:35
Enhance the sqlite3_str_new() interface so that it always returns a valid and non-NULL pointer even in an OOM condition. (check-in: ed5b0968 user: drh tags: trunk)
12:19
Correct output for the fullkey column of json_each() when the total JSON input is a simple value, not an array or object. (check-in: b45b1885 user: drh tags: trunk)

2018-05-12
23:56
In the CLI, allow comment lines that begin with '#', but only in a context where a dot-command is allowed. In other words, '#' at the beginning of a line in the middle of an SQL statement is just part of the SQL. (check-in: 4ee136d6 user: drh tags: trunk)
2018-05-11
19:11

13:46
Make the internal dynamic string interface available to extensions using the new sqlite3_str object and its associated methods. This is mostly just a renaming of internal objects and methods to use external names, through there are a few small wrapper functions. (check-in: 87f261f0 user: drh tags: trunk)
10:11
Fix a typo in a comment used for documentation. No code changes. (check-in: b866693e user: drh tags: trunk)

In SQLITE_ENABLE_BATCH_ATOMIC_WRITE builds on F2FS file-systems, invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE if an SQLITE_FCNTL_COMMIT_ATOMIC_WRITE call fails. Also, do not use an atomic transaction to create the initial database. This is because if an error occurs while writing to the db file, any changes to the file-size do not seem to be rolled back automatically.

The output of sqlite3_trace() now shows each command of a trigger as it is evaluated. This feature involved major changes to the parser, such as removing the ExprSpan object and replacing it with a new mechanism for capturing the original SQL text of phrases in the input SQL. (check-in: 0fdf97ef user: drh tags: trunk)

18:19
Enhance the Lemon parser generator so that it creates a faster parser at the cost of slightly larger parser tables. Add the ability to measure coverage of the generated state machine when compiling with the -DYYCONVERGE option. In SQLite, add the SQLITE_TESTCTRL_PARSER_COVERAGE test-control to query the new parser coverage feature. (check-in: 1b22b42e user: drh tags: trunk)
17:36
The previous check-in had an error in the coverage reporting logic. (Closed-Leaf check-in: ec9b19eb user: drh tags: lemon-improvements)
17:14
Change the coverage measurement logic in the lemon-generated parser so that it only checks for coverage of state/lookahead pairs that are valid syntax. It turns out that some states are unreachable if the lookahead is not valid syntax, because the states are only reachable through a shift following a reduce, and the reduce does not happen if the lookahead is a syntax error. (check-in: 9dce4650 user: drh tags: lemon-improvements)
16:13
In the lemon-generated parser, do not report the End-of-input character and the wildcard character as missed coverage. (check-in: 3fe96487 user: drh tags: lemon-improvements)

04:15
Enhance LEMON so that it generates the action table in such a way that no range check is needed on the lookahead table to verify that the next input token is valid. This makes the lookahead table slightly larger (about 120 bytes) but helps the parser to run faster. (check-in: 7eb0198d user: drh tags: lemon-improvements)

In the LEMON-generated parser, rearrange the meanings of integer action codes so that reduce actions occur last. This means that the most common case (reduce actions) can be recognized with a single comparison operation, thus speeding up the main parser loop, slightly. (check-in: 7bfe7a36 user: drh tags: lemon-improvements)

2017-09-27
16:51
Disable tests for the LIKE optimization when ICU is enabled, since the LIKE optimization only works for the built-in LIKE operator and ICU overrides the built-in. (check-in: f5ef2e1b user: drh tags: trunk)

12:52
Partial backout of check-in [e0af9a904076]. It turns out we do need some extra space at the end of the record blob as an overrun area to use when decoding a maliciously malformed record. (check-in: 403b88a8 user: drh tags: trunk)
00:24
Update the configure script so that it looks for tclsh8.7 ahead of tclsh8.6. (check-in: 0a12915b user: drh tags: trunk)

In the Windows VFS, when trying to open a database file read/write, if it fails check to see if the file exists and is read-only and immediately fall back to a read-only open attempt, rather than running the AV retry loop. (check-in: 5d03c738 user: drh tags: trunk)
20:03
In the Windows VFS, do not emit an SQLITE_CANTOPEN error log message when falling back from SQLITE_OPEN_READWRITE to SQLITE_OPEN_READONLY. Wait until the open fails completely. (check-in: fa3f5bcc user: drh tags: trunk)

10:24
Fix a bug in tool/mksourceid.c: The mksourceid.c program was incorrectly including the "# Remove this line" line of the Fossil-generated "manifest" file in the SHA3 hash. That means that all SQLITE_SOURCE_IDs for trunk versions going back to check-in [30966d56] (2017-08-22) are incorrect. (check-in: 65765222 user: drh tags: trunk)

2017-09-17
19:45
Do not make the assumption (as check-in [4da49a95c0f07] incorrectly did) that the ExprList returned by sqlite3ExprListDup() would never be passed into sqlite3ExprListAppend(). Include a new test case that shows this sometimes does happen. (check-in: 29227d00 user: drh tags: trunk)
2017-09-16

Fix a harmless typo, but one that would show up in the documentation if not fixed. (check-in: e4b1dd36 user: drh tags: trunk)
19:49
Add support for F2FS atomic writes. Untested at this point. (check-in: 416973ed user: dan tags: batch-atomic-write)
15:08
Enhance the built-in date/time functions so that they can be used in CHECK constraints, in the WHERE clause or partial indexes, and index expressions, provided that none of the non-deterministic keywords ("now", "localtime", "utc") are used as arguments. (check-in: a90c062d user: drh tags: trunk)
14:36
New test cases for date/time functions in indexes on expressions, in the WHERE clause of partial indexes, and in CHECK constraints. (Closed-Leaf check-in: b7f70c7f user: drh tags: index-on-date-func)
13:17
Combine the Parse.ckBase and Parse.iSelfTab fields into just Parse.iSelfTab. This fixes a problem with date/time functions in check-constraints. Add some test cases for date/time functions in index expressions and check constraints. (check-in: 22eda098 user: drh tags: index-on-date-func)
2017-07-19
19:48
Allow indexes to be created on date/time functions as long as the 'now' date and the 'localtime' and 'utc' modifiers are not used. (check-in: 0a5e1c04 user: drh tags: index-on-date-func)
18:01
Remove some 'breakpoint' commands in test files. (check-in: d14fc621 user: mistachkin tags: trunk)

Fix another harmless compiler warning. Get the MSVC makefile working with unionvtab. (check-in: d49639c2 user: drh tags: trunk)
20:22
Suppress harmless compiler warnings in union-vtab. (check-in: 4d147a1e user: drh tags: trunk)

18:50
Add test cases to unionvtab.test. (check-in: 6c9128e1 user: dan tags: trunk)
18:19
Add the union-vtab extension - still experimental and under active development. (check-in: 948f9504 user: drh tags: trunk)
17:34
Do not use the flattening optimization for a sub-query on the RHS of a LEFT JOIN if that subquery reads data from a virtual table. Because it prevents the planner from creating an automatic index on the results of the sub-query, the flattening optimization sometimes slows things down in this case. (check-in: 9dbae1df user: dan tags: trunk)
17:13
Avoid creating an automatic index on the RHS of a LEFT JOIN to optimize an IS term. Fix for [ce68383b]. (check-in: d2f0b2e8 user: dan tags: trunk)

17:46
Interchange to branches within an "if" statement in sqlite3_value_pointer() in order to work around a bug in gcc. (Closed-Leaf check-in: 8a606e4a user: drh tags: branch-3.20)

Merge the pointer-type enhancement from the 3.20 branch. (check-in: 9e8e1c4a user: drh tags: trunk)
12:41
Comment changes clarifying details of the pointer-type parameter. No changes to code. (check-in: e4579e50 user: drh tags: branch-3.20)
12:27
Add the pointer-type parameter to sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer(). The pointer type is a static string that must match (according to strcmp()) or else the pointer is passed as a NULL. This is a security measure to prevent crossing pointers between different extensions. (check-in: e1196567 user: drh tags: branch-3.20)
11:39
Improve the sqlite3_result_pointer() interface so that it cannot be faked using sqlite3_result_null() and sqlite3_result_subtype(). (Closed-Leaf check-in: c13264d5 user: drh tags: pointer-types)
00:40
Add an experimental "pointer type" parameter to sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer(). The pointer type is a string that must compare equal using strcmp() or else the pointer comes through as a NULL. (check-in: 211cce04 user: drh tags: pointer-types)
2017-07-15
20:48
Add the "unionvtab" virtual table extension in ext/misc/unionvtab.c. (check-in: 62a86aa6 user: dan tags: union-vtab)
20:44
Merge the fix for ticket [a4e06e75a9ab61a12] from trunk. (check-in: b64d64c8 user: drh tags: branch-3.20)
20:33
Fix a register allocation problem in PRAGMA integrity_check that caused the same register to be used for two different purposes on the first ATTACHed database if the schema for the ATTACHed database was noticable more complex than the schema for the first database. Fix for ticket [a4e06e75a9ab61a1]. (check-in: 253945d4 user: drh tags: trunk)

Include a hint in the header comment of the LSM1 makefile about how to set the LSMOPTS variable. (check-in: b5e3b264 user: drh tags: trunk)
15:32
Update the Makefile for LSM1 so that the LSMOPTS can be set prior to including the Makefile, in order to add platform arguments such as -fPIC. (check-in: fe319bcd user: drh tags: trunk)
15:18
Fix a typo in the header comment to the remember extension. No code changes. (check-in: 604b9664 user: drh tags: trunk)
15:14
Change the name of the STMT virtual table to SQLITE_STMT. Also remove the first column of that virtual table, which was a pointer leak. (check-in: 1bc4e934 user: drh tags: trunk)
13:24
Minor updates to requirements marks and documention. No changes to code. (check-in: 8f6dd5e2 user: drh tags: trunk)

Improvements to the documentation for SQLITE_PREPARE_PERSISTENT. No code changes. (check-in: 26577814 user: drh tags: trunk)
20:11
Fix documentation typo. No changes to code. (check-in: 9319f7b7 user: drh tags: trunk)
19:11
Update header comments on the carray() and remember() extensions to bring out the fact that the pointer arguments must be bound using sqlite3_bind_pointer(). (check-in: 55f53965 user: drh tags: trunk)
18:09
Add new interfaces sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer() used to safely move pointer values through SQL without exposing underlying memory address information. (check-in: 72de49f2 user: drh tags: trunk)
17:56
Fix an incorrect type signature for the loadable extension pointer for sqlite3_result_pointer(). (Closed-Leaf check-in: 0bd7875b user: drh tags: bind-pointer)
17:54
Add the three new pointer interfaces to the loadable extension mechanism. Update sqlite3_value_subtype() documentation to remove the statement about it not being used internally. (check-in: e5a51803 user: drh tags: bind-pointer)
17:48
Update the FTS3 extension to use sqlite3_result_pointer() and sqlite3_value_pointer() for passing FTS3 cursor objects from the table into functions such as snippet(). (check-in: 0fa2e170 user: drh tags: bind-pointer)
17:34

Smaller and faster implementation for vdbeFreeOpArray() and freeP4(). (check-in: 0c805935 user: drh tags: trunk)
18:05
Fix harmless compiler warnings about incomplete structure initializers. (check-in: 604c11d1 user: drh tags: trunk)
17:26
Remove unnecessary EP_Leaf settings on the Expr object. (check-in: f951c8b7 user: drh tags: trunk)

The EP_Resolved flag on the Expr object is not required for correctness nor performance, so remove it. (check-in: 54f55d3b user: drh tags: trunk)
14:10
Clarification and simplification and result column naming logic. (check-in: 68824a43 user: drh tags: trunk)
14:03
Fix a problem in an lsmtest test case caused by writing data in "text" mode instead of "binary". (check-in: 3e56a79a user: dan tags: trunk)
12:19
Compile cleanly with SQLITE_OMIT_UTF16. (check-in: 783100b8 user: drh tags: trunk)
2017-07-11
20:36
In lsm, attempt to unmap the database file before truncating it when disconnecting. A mapped file may not be truncated on win32. (check-in: 39069941 user: dan tags: trunk)
19:55
Simplify the way in which the database file is truncated when the last connection disconnects. Also ignore the error code from the xTruncate call - as truncating a database file is always optional. (check-in: b0a49d90 user: dan tags: trunk)
18:11
Fix harmless compiler warnings in the core. (check-in: 55e93f25 user: drh tags: trunk)

16:36
Fix harmless compiler warnings seen with MSVC for lsm1. (check-in: cf6da4a5 user: mistachkin tags: trunk)
13:59
Add support for tab-completion (using the ext/misc/completion.c virtual table) to the command-line shell. (check-in: 95cd1d9f user: drh tags: trunk)
13:34
Change the src/shell.c file so that it is generated from a new script at tool/mkshellc.tcl and the template file src/shell.c.in, and automatically includes the extensions it needs out of ext/misc. (check-in: 17e0bb12 user: drh tags: trunk)
02:53
Fix a backup2 test case so that it works on FreeBSD. (check-in: 724819b4 user: drh tags: trunk)
02:05
Add the "phase" output column on the COMPLETION table-valued function, for debugging. Improved comments on the implementation. (check-in: 0e213555 user: drh tags: trunk)
01:38
The COMPLETION virtual table now looks at the names of databases, tables, and columns in addition to SQL keywords. (check-in: 1cc97711 user: drh tags: trunk)
00:09
Incomplete implementation of the COMPLETION table-valued function. So far it only works for SQL keywords. (check-in: caefbc72 user: drh tags: trunk)

21:32
Fix harmless compiler warnings in lsmtest. (check-in: bd8a1fb9 user: mistachkin tags: trunk)

Fix errors in comments in the STMT virtual table. No code changes. (check-in: 9a8f045d user: drh tags: trunk)
20:33
Minor cleanup and refactoring of the Win32 VFS for lsm1. (check-in: bf7eda67 user: mistachkin tags: trunk)
19:54
Another spelling error in the README.md file. (check-in: 05129374 user: drh tags: trunk)

Cleanup header usage in lsmtest for files that require _O_BINARY. (check-in: f3a6a64e user: mistachkin tags: trunk)
18:52
Updates to the repository README.md file. (check-in: 7bfd3ab7 user: drh tags: trunk)
18:33
In LSM, avoid calling the VFS xTestLock method to test for a lock that conflicts with one held by the same process. The results of such a call are considered undefined (since they are different under win32 and posix). (check-in: a82a9bea user: dan tags: trunk)
18:04
Add the "--newlines" option to the ".dump" command in the shell to disable the newline escaping mechanism. (check-in: bde431b1 user: drh tags: trunk)
17:00
When multiple constraints need to be evaluated for a row, do any constraints that involve correlated subqueries last. Hence, the priority is index-covered constraints first, correlated subquery constraints last, and all others in the middle. This is a follow-on and improvement to the push-down optimization of check-in [d7bb79ed]. (check-in: c4cb9048 user: drh tags: trunk)
16:38
Additional debugging Noop-comment in the constraint generator when wheretrace is enabled. (Closed-Leaf check-in: 0ca7474f user: drh tags: defer-where-subqueries)

Fix another problem on this branch. (check-in: a4fc9811 user: dan tags: defer-where-subqueries)
14:39
Fix a problem causing non-covered WHERE terms to be evaluated before covered WHERE terms. (check-in: 7d3cb39f user: dan tags: defer-where-subqueries)
14:33
When testing non-indexed WHERE constraints, test those that involve correlated sub-queries last of all. This increases the chances of not having to run the sub-query at all. (check-in: 1f9c1f35 user: dan tags: defer-where-subqueries)
13:24
For sqlite3TreeView() debugging output, show the Expr.flags field on scalar subqueries. (check-in: dc857a96 user: drh tags: trunk)
12:07
Update error message text for standard error codes to better describe the latest usage of those error codes. Modify sqlite3_open_v2() so that it does return a valid sqlite3 object in the event of SQLITE_MISUSE due to bad open flags, so that sqlite3_errmsg() does not report "out of memory" in that case. (check-in: f27b6370 user: drh tags: trunk)
11:17
Remove the error message text from disused error codes such as SQLITE_EMPTY and SQLITE_FORMAT. (check-in: 871752f2 user: drh tags: trunk)
2017-07-09
18:55
Always make "column%d" column-names 1-based, never 0-based. (check-in: 70096c50 user: drh tags: trunk)
00:30
Make sure the columns of a VALUES() clause are named "column%d" even if the VALUES() clause is a subquery in the FROM clause of an outer query. (check-in: acf3b9cc user: drh tags: trunk)
2017-07-08

Fix comment in the Win32 VFS for lsm1. (check-in: 12a421bc user: mistachkin tags: trunk)
21:15
For lsmtest, use a more portable means of setting open() files to binary. (check-in: aea6e0ff user: mistachkin tags: trunk)
20:35
Adjust copy_file() lsmtest function so it works properly for locked database files on Win32. (check-in: 54a38555 user: mistachkin tags: trunk)
20:06
Add the "PRAGMA secure_delete=FAST" option, which overwrites most deleted content without increasing the amount of I/O. Deleted content might persist on the free page list, however. And extra CPU cycles are used for zeroing, of course. (check-in: 38978ce6 user: drh tags: trunk)
19:43
Change the error message text for SQLITE_ERROR to omit the part about "missing database" as that meaning is now obsolete (since approx SQLite 2.0). (check-in: 732f90d6 user: drh tags: trunk)
19:22
Fix typos in Win32 VFS for lsm1. (check-in: 0961ec87 user: mistachkin tags: trunk)

19:02
Enhance the MSVC makefile 'clean' target to handle lsm1. (check-in: 2d6faebc user: mistachkin tags: trunk)
18:31
Add support for LSM_DEBUG to the MSVC makefile for lsm1. (check-in: 277a7fed user: mistachkin tags: trunk)
18:06
In the command-line shell, when running ".schema" give a sensible error when the database file is locked. (check-in: cc329eb8 user: drh tags: trunk)
17:57
Fix the usleep() macro in the Win32 test code for lsm1. (check-in: 63599fa5 user: mistachkin tags: trunk)
17:43
Add new PRAGMAs: "function_list", "module_list", and "pragma_list". All are enclosed within #ifdef SQLITE_INTROSPECTION_PRAGMAS. The compile-time option is not on ctime.c yet, since these are still experimental and one can always test "PRAGMA pragma_list" and see whether or not it returns an empty set. (check-in: e0b6ae92 user: drh tags: trunk)
17:33
Add the "Pragma_list" pragma. Put all three pragmas created on this branch inside of #ifdef SQLITE_INTROSPECTION_PRAGMAS. (Closed-Leaf check-in: 2f3c3781 user: drh tags: list-pragmas)
16:46
Improve clarity in the Win32 VFS for lsm1. (check-in: 9c7a9e80 user: mistachkin tags: trunk)
16:29
Add support for LSM_DEBUG_MEM to the MSVC makefile for lsm1. (check-in: 3340de83 user: mistachkin tags: trunk)
16:27
Remove a block from the Win32 VFS for lsm1 that is now superfluous. (check-in: 5f726f28 user: dan tags: trunk)
16:09
In lsmtest, use an empty string instead of ":memory:" when requesting a temporary database from SQLite. This prevents other test code from trying to unlink() ":memory:", which fails on win32. (check-in: 281ad505 user: dan tags: trunk)
16:07
Remove a block from the Win32 VFS for lsm1 that is now superfluous. (check-in: db4a4140 user: mistachkin tags: trunk)
16:06
Memory reallocation fix for the Win32 VFS for lsm1. (check-in: 5a3140e4 user: mistachkin tags: trunk)
16:00
Enhance the sqlite3VdbeMultiLoad() interface to automatically generate the OP_ResultRow opcode on PRAGMA implementations, for a small reduction in the library footprint. (check-in: c46f0f07 user: drh tags: trunk)
15:43
Add new pragmas: "function_list" and "module_list" (check-in: e5f01d7f user: drh tags: list-pragmas)
14:26
Merge recent enhancements from trunk. (check-in: 73d0fc02 user: drh tags: bind-pointer)

Exploit the fact that Expr.pRight and Expr.x are never used at the same time for a small performance gain. (check-in: aacbb9a4 user: drh tags: trunk)
12:58
More efficient and compact implementation of walkExpr(). (check-in: 115d4b83 user: drh tags: trunk)

11:39
The SQLITE_EXTRA_IFNULLROW compile-time option causes OP_IfNullRow opcodes to be issued for references to the right-hand side table of *any* flattened join, not just LEFT JOINs. This puts extra stress on the OP_IfNUllRow opcodes for testing purposes. (check-in: 1a074c8a user: drh tags: branch-3.19)
00:28
The TK_IF_NULL_ROW expression node must be treated as a variable that references the table Expr.iTable. Proposed fix for ticket [7fde638e94287d2c]. (check-in: b30a364a user: drh tags: branch-3.19)

18:02
Fix a problem in "PRAGMA foreign_key_check" in handling a WITHOUT ROWID child table with an INTEGER PRIMARY KEY parent key. Also, if an FK violation is detected in a WITHOUT ROWID child table, do not try to read and return the rowid. The second column returned by "PRAGMA foreign_key_check" in this case (WITHOUT ROWID child table) is now always set to NULL. (check-in: 690870bd user: dan tags: trunk)
17:03

14:16
Fix memory leaks in the code on this branch. Make use of the sqlite3_index_constraint.usage field. Do not try to handle ORDER BY terms with explicit COLLATE clauses - they don't get passed to the vtab layer anyway. (check-in: 0cd75a87 user: dan tags: schemalint)

19:03
Add the TK_IF_NULL_ROW opcode to deal with non-NULL result columns in the result set of a view or subquery on the RHS of a LEFT JOIN that gets flattened. (Closed-Leaf check-in: 3a5860d8 user: drh tags: left-join-view)
17:30
When doing a DISTINCT query using an index, try to use the index to skip ahead to the next distinct element, rather than doing a full scan of the index. (This is the "skip-ahead-distinct" optimization.) (check-in: f489b5bb user: drh tags: trunk)
17:18
An initial attempt to optimize VIEWs that occur as the right operand of a LEFT JOIN. This particular check-in does not work correctly because it does not deal with the case of columns in the VIEW that return non-NULL even when all columns in the table of the VIEW are NULL because of the LEFT JOIN. (check-in: 1838a59c user: drh tags: left-join-view)

Only use the skip-ahead-distinct optimization if the index has been analyzed and we know that a skip-head is likely to skip over at least 11 rows. The magic number 11 was determined by experimentation. (check-in: 0cf16dec user: drh tags: skip-ahead-distinct)
09:45
Allow a user column name to be used on the LHS of a MATCH operator in FTS5. (check-in: 6f54ffd1 user: dan tags: trunk)
01:19
Forward port the skip-ahead-distinct branch which was abandoned for some reason that I do not recall. This port should have been achived by a merge of trunk into the previous head of skip-ahead-distinct, but that did not work. So I had to manually "rebase" the changes. (check-in: 132339a1 user: drh tags: skip-ahead-distinct)
00:12
Fix a regression caused by the fix for ticket [6c9b5514077fed34551f98e64c09a1] - control characters allowed in JSON. (check-in: 8e7b6118 user: drh tags: trunk)

Make sure the RTree sqlite3_blob handle is reset prior to renaming the table. (check-in: 1cdae2db user: drh tags: trunk)

13:38
Enhance the Index and Table objects so that they remember if their stats come from the sqlite_stat1 table. Make the "PRAGMA stats" an SQLITE_DEBUG only pragma. Add the flags column to "PRAGMA stats".

02:04
Fix a test case that was made to fail by the LIKE optimization enhancement in check-in [158290c0ab] but which went unnoticed because test builds were running with ICU enabled and ICU disables the LIKE optimization. (check-in: 218b2bbb user: drh tags: trunk)

01:41
Remove an incorrect ALWAYS() macro from balance_nonroot(), which could result in corrupt databases if it were optimized out. This ALWAYS was added only two weeks ago (check-in [f9f2e23bbd68a]) and has never appeared in an official release. (check-in: e447b23c user: drh tags: trunk)
00:18
Add the built-in affinity() SQL function. (check-in: 57e40e1c user: drh tags: affinity-sql-func)

Combine the implementations of the ".tables" and ".indexes" commands in the command-line shell. The ".indexes" command now puts the indexes in multiple columns, just like ".tables" and shows all indexes in all attached databases. (check-in: def29333 user: drh tags: trunk)
19:37
The schema name "main" is always an acceptable alias for the primary database even if the primary database is renamed using SQLITE_DBCONFIG_MAINDBNAME. (check-in: 2f481b85 user: drh tags: trunk)
18:18
Change the output format of the ".databases" command in the command-line shell so that it shows the schema name, a colon, and the corresponding filename. (check-in: 8558512e user: drh tags: trunk)
