2022-07-01
21:03
Do not attempt the OP_Count optimization on queries with HAVING clauses. This fixes a problem exposed by [2cf373b10c9bc4cb]. (Leaf check-in: 566b7842 user: dan tags: trunk)
19:42
Performance improvement in resolveP2Values(). Save over 1 million CPU cycles by omitting the loop termination condition and exiting when the OP_Init (always the first opcode in any VDBE program) is encountered. (check-in: bb179140 user: drh tags: trunk)
2022-06-30

19:43
Allow flattening of a subquery that is the right operand of a LEFT JOIN in an aggregate query as long as there is no GROUP BY clause. (The GROUP BY clause will interfere with the operation of the TK_IF_NULL_ROW expression nodes.) (check-in: 2cf373b1 user: drh tags: trunk)
19:30
Increase the version number to 3.40.0 so as to begin the next development cycle. (check-in: 4542e323 user: drh tags: trunk)

11:05
In sqlite3WhereBegin, do not proceed with coding the loop if an error is detected as part of WHERE expression analysis. For for the assertion-fault described by forum post c3496cf6b1. (check-in: db5266de user: dan tags: trunk)
11:02

2022-06-23
22:43
New test cases for query flattening with LEFT JOIN. (Closed-Leaf check-in: 27f68e47 user: drh tags: flatten-left-join)
20:56
Reintroduce flattener constraint (3c), but this time make it apply only if the outer query holds a GROUP BY, not if the outer query is an aggregate. (check-in: 641dfb91 user: drh tags: flatten-left-join)
15:15
Add back the ability to flatten a LEFT JOIN subquery - previously removed due to ticket [cad1ab4cb7b0fc344]. (check-in: f8fe936a user: drh tags: flatten-left-join)
12:36
Minor correction to a comment. No code changes. (check-in: 5fa00959 user: drh tags: trunk)
2022-06-22
18:51
Enhance the TCL scrip that generates sqlite3-all.c so that it outputs all text in its original order. (check-in: 83ff1a28 user: drh tags: trunk)
18:33
Fix requirements marks that changed due to typo fixes in the documentation. (check-in: 5247df05 user: drh tags: trunk)
15:55
More comment fixes. No changes to code. (check-in: 5c9133ef user: drh tags: trunk)
14:43
Allow more line with on the debugging output for SrcItem elements in the parse tree. This affects debugging builds only and is a no-op for production builds. (check-in: edbe24e7 user: drh tags: trunk)
14:25
Additional enhancements to comments. No changes to code. (check-in: d9a32044 user: drh tags: trunk)

13:41
Allow a HAVING clause on any aggregate query, even if there is no GROUP BY clause. This brings SQLite into closer agreement with PostgreSQL and fixes the concern raised by forum post 1a7fea4651. (check-in: 9322a7c2 user: drh tags: trunk)
2022-06-20
19:12
Add an ALWAYS() macro to an always-true branch. (check-in: 364645d8 user: drh tags: trunk)
18:26
Do not allow FROM-clause terms on the left side of a RIGHT or FULL JOIN to be reordered. forum post 6650cd40b5634f35. This is probably more strict that necessary to get correct behavior, but for the first release that supports RIGHT/FULL JOIN it is perhaps better to be correct than fast. A less strict constraint might be to prohibit FROM-clause terms that originate on the left side of a RIGHT JOIN from crossing from the right side to the left side of a LEFT JOIN. Revisit this later. (check-in: 238453ff user: drh tags: trunk)
17:04
Do not allow an ON clause to references tables to its right if there is a RIGHT or FULL join anywhere in the query. Other RDBMSes prohibit this always, but SQLite must allow ON clauses to reference tables to their right for legacy compatibility, unless there is a RIGHT or FULL join someplace in the query, in which case there is no legacy to support. (check-in: e615dbe0 user: drh tags: trunk)
12:42
The fix at [cab9b4cccd13bf0a] was incomplete, as demonstrated by forum post 57bdf2217d. This check-in should complete the fix. (check-in: fb0a23b6 user: drh tags: trunk)
2022-06-19
16:55
Follow-up to check-in [0057bbb508e7662b] - ensure that the database page has been initialized prior to continuing with the optimization. If the page is not initialized, that indicates that the database is corrupt. dbsqlfuzz 09ee46becd5e6d1b2a55c9f8ad767335a90aadb0. (check-in: 11162446 user: drh tags: trunk)
2022-06-18
20:20

14:50
Abandon a query-invariant check in fuzzcheck if the call to sqlite3_bind_value() returns anything other than SQLITE_OK or SQLITE_RANGE. (check-in: d31e1cd2 user: drh tags: trunk)

21:31
Fix the OP_Concat operator such that when concatenating a BLOB with an odd number of bytes on a database that is UTF16, the size of the resulting string is reduced to a multiple of two. (check-in: 5eb2c236 user: drh tags: trunk)
17:11

Allow integers and floating point numbers to compare equal. (Closed-Leaf check-in: 0fe2e465 user: drh tags: query-invariants)
16:09
Improve query-invariants to the point that it would have discovered the [f23a429d4153518d] bug if that bug had not already been fixed. (check-in: 2a7251ed user: drh tags: query-invariants)
15:52
Only run query-invariant checks after the original query has run to completion, so that we know it does not error-out on a subsequent row. (check-in: d1fc857b user: drh tags: query-invariants)
15:11
Fix the virtual table detection mechanism to avoid false-positives that were blocking all failures. Then fix a few of the additional problems that are revealed by that fix. More fixes are needed. (check-in: 42b2e667 user: drh tags: query-invariants)
12:25
Fix the new --query-invariants option on fuzzcheck so that it does not use an unprotected sqlite3_value object as an argument to sqlite3_value_int64(). (check-in: d9f82015 user: drh tags: trunk)
11:39
Avoid omitting the rhs of FULL JOINs in cases where it is only correct to omit the rhs of a LEFT JOIN. Fix for the problem reported by forum post 5610c17c3d. (check-in: f23a429d user: dan tags: trunk)

2022-06-10
16:41
The same restrictions on the use of WHERE clause terms to drive indexes in the presence of RIGHT JOINs also apply to the use of WHERE clause terms to manufacture automatic indexes. This fixes a problem identified by forum post 51e6959f61. (check-in: 342c501f user: drh tags: trunk)

15:30
Add restriction (29) to the query flattener - do not allow flattening that would leave both EP_InnerON and EP_OuterON constraints on the same join term. (Leaf check-in: c585d6a4 user: drh tags: right-join-query-flattener)
13:13
New test cases refute check-in [3f45007d544e5f78]. (check-in: 12d3c96c user: drh tags: right-join-query-flattener)
12:46
Do not allow a partial index scan on the left table of a RIGHT JOIN, because since the index is partial, some rows will be omitted from the scan, and those rows will subsequently be picked up by the no-match logic in the right-join post-processing loop. forum post c4676c4956. (check-in: 615c0026 user: drh tags: trunk)
12:35

17:36
Minor simplification to ALTER TABLE logic. (check-in: 01beb036 user: drh tags: trunk)
17:13
Corrected a broken HTML comment (was using a C-style comment closer). (check-in: db742e3e user: stephan tags: trunk)
15:33
Fix another problem with ALTER TABLE and UPDATE...FROM in triggers. (check-in: 33cf1223 user: dan tags: trunk)
15:04
Fix further issues with ALTER TABLE and triggers that contain UPDATE..FROM statements. (check-in: 53fbc269 user: dan tags: trunk)
14:41
Omit an unnecessary branch. (check-in: f56473f9 user: drh tags: trunk)
03:27
fiddle: added an option to completely wipe/reset the db. The Options area can now be toggled on/off via tapping the label at its top. Running the input SQL is now limited to the selected area if any text is currently selected, per suggestion in the forum. (check-in: d100283e user: stephan tags: trunk)
2022-05-26
19:10
Fix issues with ALTER TABLE and triggers containing "UPDATE...FROM" statements. (check-in: 2fba0d41 user: dan tags: trunk)
17:33
Correct handling of outer joins in the FROM clause of an UPDATE statement that occurs inside of a trigger. Follow-on to [98b3816bbaf539ea]. (check-in: 664a49fa user: drh tags: trunk)
14:46
Clarification of the meaning of the N parameter in sqlite3_db_name(). Documentation only. No changes to code. (check-in: f22f41d2 user: drh tags: trunk)
05:18
Fixed a minor cut/paste mistake in the previous checkin. Affects only internal docs. (check-in: 37e37648 user: stephan tags: trunk)
05:08
Makefile.in: added explanations, intended for maintainers and hackers, of the various emcc flags used for building the wasm files. No code or build rule changes. (check-in: 1a159159 user: stephan tags: trunk)
2022-05-25
13:10
Slight increase in the accuracy of log10(). (check-in: c48a735b user: drh tags: trunk)
12:49
Do not allow the right operand of a RIGHT JOIN to be reordered with other FROM clause terms that are even further to the right. Fix for the issue identified by forum post 5cfe08eed6. (check-in: 4be0c60e user: drh tags: trunk)
11:17
Add in a VdbeCoverage() macro accidentally omitted from [d64ae49a1f251317]. (check-in: 18b5cea0 user: drh tags: trunk)
11:09
Fix the UPDATE-FROM logic so that it works the same as PostgreSQL when the FROM clause contains an outer join. (check-in: 98b3816b user: drh tags: trunk)
08:51
Got the sqlite3-api JS bits wrapped up in deferred-load module. Whether that's going to be easier to use, in practice, remains to be seen. Consolidated two of the test-related JS files. (check-in: dd83cc05 user: stephan tags: trunk)
04:38
Renamed EXPORTED_FUNCTIONS.sqlite3 to EXPORTED_FUNCTIONS.sqlite3-api to avoid any potential confusion about that file (not) being an sqlite3 database. (check-in: 3d6245c6 user: stephan tags: trunk)
04:35
Add the ability to import/export db files into/from fiddle. (check-in: e0c30438 user: stephan tags: trunk)
04:20
Further minor cleanups and docs in the fiddle app and worker. (Closed-Leaf check-in: 199e0179 user: stephan tags: fiddle-local-db)
03:08
fiddle: refactored so that it no longer exposes any global symbols. Doing so with the main sqlite3.api module will be much tricker. (Edit: it _does_ export a global symbol, but it's the function to init the module instead of the module itself. Not sure that's any cleaner.) (check-in: cd227be8 user: stephan tags: fiddle-local-db)
02:32
An attempt to get UPDATE FROM working when the FROM clause contains a RIGHT or FULL JOIN. (Closed-Leaf check-in: a124e4f9 user: drh tags: update-from-right-join)
2022-05-24
22:16
fiddle: added support for exporting (downloading) the current db file. To do this we had to fall back to named dbs, instead of defaulting to an in-memory one, but the virtual filesystem is an in-memory FS, so the end effect is the same. (check-in: 7c7fd34c user: stephan tags: fiddle-local-db)
19:01
fiddle: initial work on loading a client-side db file. Works but requires some cleanup. Export is not yet implemented. (check-in: 0fa8378c user: stephan tags: fiddle-local-db)
16:05
When an ON clause on an INNER JOIN references a table to the right of of the join, just convert the ON clause to an ordinary WHERE clause term, in order to be compatible with older versions of SQLite. See forum thread 687b0bf563a1d4f1 for details. (check-in: 2b6ebba2 user: drh tags: trunk)
14:45
Use more descriptive var names in ext/fiddle/Makefile. (check-in: 2f9a42fb user: stephan tags: trunk)
14:36
fiddle: lots of generic refactoring, restructuring, and cleanup in the higher-level code. Added push-fiddle ext/fiddle/Makefile target to push the fiddle app to a remote server via rsync. (check-in: ed19fef3 user: stephan tags: trunk)
01:15
wasm/JS: minor doc updates, corrected bind()ing of the undefined value to behave as documented, removed some superfluous code. (check-in: 526c8c72 user: stephan tags: trunk)
00:35
wasm/JS: documented DB.selectValue() and corrected the fetching of NULL columns via Stmt.get(). (check-in: 70f91fab user: stephan tags: trunk)
00:22
wasm/JS: added support for scalar UDFs. Fixed a deallocation problem with bind()ed strings/blobs. (check-in: 325a9ee3 user: stephan tags: trunk)
2022-05-23
19:38
wasm: minor refactoring and doc updates. (check-in: 6044605b user: stephan tags: trunk)
16:54
fiddle: cleaned up and documented the status-loading progress mechanism in prep for reusing it in the sqlite3-api worker. (check-in: 107e3497 user: stephan tags: trunk)
13:55
wasm: added missing 'use strict' and fixed an undeclared var use caught by that. (check-in: c16a7f49 user: stephan tags: trunk)
13:52
wasm: corrected isSupportedBindType() to behave as documented. (check-in: 7e2d2e80 user: stephan tags: trunk)
12:37
New test cases to further demonstrate the difference in name matching rules for LEFT JOIN versus RIGHT JOIN that protect legacy behavior. Forum thread e90a8e6e6fa652ac. (check-in: 2c586060 user: drh tags: trunk)
11:51
Add an assert() to clear a harmless static-analyzer warning. (check-in: 919ba2f0 user: drh tags: trunk)
10:57
Do not run the subroutine that materializes a view or subquery until just before the materialization is actually needed, so that if the materialization turns out to never been needed, unnecessary work can be avoided. (check-in: d64ae49a user: drh tags: trunk)
01:11
WASM: removed the in64-related bindings, as MDN says that calling a wasm function which has an int64 type in its signature will currently throw because JS has no 64-bit integer support. Those bindings now use doubles and simply hope that the user doesn't exceed their integer precision (2^53-1, approx 9 quadrillion). (check-in: 392e8482 user: stephan tags: trunk)
2022-05-22
22:10
WASM: an arg handling fix for DB.exec({multi:true...}). (check-in: 0d6332f7 user: stephan tags: trunk)
22:00
WASM: added exec(), execMulti(), and several getters. Various touchups and fixes. (check-in: b790c91b user: stephan tags: trunk)
19:09
Implemented Stmt.get() and friends for WASM OO #1 wrapper. Added basic tests for prepare/step/get. Restructured module init output to introduce only 1 global-scope symbol instead of 2. (check-in: 601dc3fa user: stephan tags: trunk)
16:25
WASM: added bindings for sqlite3_compileoption_get/used(), moved OO #1 into sqlite3-api.js since it can only be used from the same thread as that API and separating them complicates client-side use. Started adding test utilities and tests for the OO1 API. (check-in: f3bc0328 user: stephan tags: trunk)
14:07
WASM OO wrapper #1: prepare() and bind() APIs are in place but are untested, pending fetch/get APIs. (check-in: 84c8f63a user: stephan tags: trunk)
00:27
Build refactoring for the fiddle/wasm bits. Set up wasm binding of a chunk of the core C API and added some infastructure for creating test pages for it. (check-in: dea098b6 user: stephan tags: trunk)
2022-05-21
21:13
Minor fiddle-related build restructuring to support upcoming development of the C-style wasm sqlite3 interface, plus some commentary about the plans and goals for that. (check-in: c7cfdd4c user: stephan tags: trunk)
18:03
Defer materializing a view or subquery until the materialization is actually needed, so that if it is not needed, not useless work is performed. (Closed-Leaf check-in: 16bf3506 user: drh tags: deferred-materialize)
15:54
Fix a typo in a comment. (check-in: 34d7045b user: drh tags: deferred-materialize)
15:12
Use the newer OP_BeginSubrtn opcode instead of OP_Integer to start the subroutine used to matrialize a view. This does not change execution but does make the byte code a little easier to read. (check-in: cebd4fd6 user: drh tags: deferred-materialize)
14:19
fiddle: refactor into main thread (UI) and worker thread (wasm module). Added bits needed to support triggering sqlite3_interrupt() but do not yet have a second SharedWorker to test it with. (check-in: 5ff33268 user: stephan tags: trunk)
00:45
fiddle: add a selection list of example queries. (check-in: 74abf039 user: stephan tags: trunk)
00:01
In the shell WASM build, call open_db() early so that we can get access to the global db handle from certain experimentation-only function without having to first run some SQL code. (check-in: 31706ef8 user: stephan tags: trunk)
2022-05-20
13:50
Added the standard sqlite license header to the the fiddle JS files. Minor internal renamings in those same files. (check-in: 67e40d99 user: stephan tags: trunk)
2022-05-19
22:04
#if'd out the '.nonce' and '.check' commends in WASM builds. (check-in: 326f79ea user: stephan tags: trunk)
21:56
#if'd out the the '.cd' and '.clone' commands for WASM builds. (check-in: fa391868 user: stephan tags: trunk)
18:14
fiddle: consolidated two duplicate CSS rules. Internal doc typo fix. (check-in: d3175a79 user: stephan tags: trunk)
17:47
Added a disclaimer about fiddle's experimental and subject-to-change/removal nature. (check-in: 75b4f574 user: stephan tags: trunk)
16:59
Merge the changes to support the "fiddle" extension. (check-in: 58585f01 user: drh tags: trunk)
16:49
When building fiddle from its own directory (e.g. from emacs instead of the normal build process), force -O0 the sake of compilation speed. The top-level build now defaults to -Oz, which is more appropriate for that case. (Closed-Leaf check-in: 56b82ae8 user: stephan tags: fiddle)
16:42
Tweaks to the fiddle make target so that it builds with all of the same extensions as the standard CLI. (check-in: d46a6cb9 user: drh tags: fiddle)
16:30
Added a toggle to swap input/output field positions and simplified setup of checkboxes which toggle a CSS class on a given element. (check-in: eae3ab10 user: stephan tags: fiddle)
16:11
Default to top/bottom layout with input on the bottom. Offer a toggle to swap input/output positions. (check-in: 362d236a user: stephan tags: fiddle)
15:58
Numerous layout tweaks, the most significant being that the layout now adapts to the window size. Swapped positions of the input/output areas. This version supports, by uncommenting a few bits, a jquery.terminal-based view but alternatives to that 300kb dependency are still under investigation. (check-in: 1aad3642 user: stephan tags: fiddle)
10:58
fiddle make target now accepts fiddle_cflags=... from the CLI to overrid -Ox and such for one-off builds. (check-in: 4609a4f8 user: stephan tags: fiddle)
10:38
Ensure that the output area is cleared of any init-time messages which the emscripten bootstrapping process emits when downloading of the wasm module is slow. (check-in: 1d8d0593 user: stephan tags: fiddle)
10:24
#if'd out the '.log' command in WASM builds. Cleaned up the user-visible parts of the WASM module initialization. (check-in: b5fa12f8 user: stephan tags: fiddle)
09:55
Split the fiddle JS code into separate pre-/post-init files to simplify editing. emcc will combine these into the final fiddle.js, so the number of output deliverables does not change. (check-in: d3d8ea01 user: stephan tags: fiddle)
09:22
Added an option to auto-clear the output area before submitting the input. Experimentally inverted the colors in the input/output areas. (check-in: 1a1e4e7f user: stephan tags: fiddle)
01:12
Replaced the toggle for the notes/caveats section of the fiddle UI with a button to remove that section. (check-in: 6661d605 user: stephan tags: fiddle)
00:38
#if'd out the '.import' command in WASM builds. Several minor cosmetic UI tweaks. (check-in: e4f87eb7 user: stephan tags: fiddle)
2022-05-18
23:40
#if out the '.load' command in WASM builds. Several UI layout tweaks. (check-in: 67d98297 user: stephan tags: fiddle)
22:58
In wasm builds, ifdef out shell commands which require file I/O, pipes, or which trigger an exit() (.quit and .exit). Documented some of the quirks and limitations of the C/WASM crossover. Keep the JS code from calling into the C code after an exit() has been triggered. (check-in: bee436e6 user: stephan tags: fiddle)
21:18
Improved handling/reporting of conditions which trigger an exit() from native code, e.g. calling the '.read' command. Added a Help button which simply submits the '.help' command. Added commented-out variants of various -Ox flags to simplify experimenting with them. (check-in: bf06ddf4 user: stephan tags: fiddle)
18:10
Code style fixes: s/char const/const char/. (check-in: 9bf042b2 user: stephan tags: fiddle)
17:40
The fiddle input/output areas now stretch and shrink as needed to account for their available space. (check-in: 4eec0545 user: stephan tags: fiddle)
17:22
Increased default size of the fiddle output area, changed the .nullvalue default in the input area, and minor CSS tweaks. (check-in: 281aaae7 user: stephan tags: fiddle)
17:14
Initial version of an sqlfiddle-style application using a WASM build of the sqlite3 shell. (check-in: af9c21c9 user: stephan tags: fiddle)
2022-05-17
15:11
Fix harmless compiler warnings in the new unixFullPathname implementation. (check-in: f7e1ceb5 user: drh tags: trunk)
15:01
Avoid treating constant expressions like "? IN ()" or "? NOT IN ()" as integers if they appear in a GROUP BY or ORDER BY clause. (check-in: d8b249e8 user: dan tags: trunk)
14:59
Add the sqlite3_db_name() interface. (check-in: 2ad15223 user: drh tags: trunk)
2020-08-14
13:23
Version 3.33.0 (check-in: fca8dc8b user: drh tags: trunk, release, version-3.33.0)
