6124 check-ins using file ext/rtree/visual01.txt version e9c25640

2022-09-24
19:54
Add the SQLITE_RECOVER_SLOWINDEXES option, for specifying that indexes should be created and populated along with tables, instead of separately at the end of the recovery operation. (Leaf check-in: ad9dba9d user: dan tags: recover-extension)
19:17
Add sqlite3_recover_step() to header file sqlite3recover.h. Update the API docs in this file. (check-in: 47f41615 user: dan tags: recover-extension)
18:05
Update things to use sqlite3_recover_step() internally. (check-in: f4b15aad user: dan tags: recover-extension)
11:32
Fiddle: move, rather than copy, data buffers between the threads. Fix the case of an uploaded db failing to install because its filename is the same as the opened db. (Leaf check-in: bcec4f96 user: stephan tags: fiddle-opfs)
10:15
Resolve "already configured" warnings from shell's main() when starting it up in fiddle mode. (check-in: 114ef355 user: stephan tags: fiddle-opfs)
10:12
Reworked out the OPFS async proxy metrics are fetched so that they play more nicely with the tight event-polling loop. (check-in: ef503ced user: stephan tags: fiddle-opfs)
07:36
Refactoring towards getting fiddle to support OPFS as a first-class citizen. Certain operations, e.g. import, export, and unlink, are not OPFS-aware. (check-in: 1b923ed6 user: stephan tags: fiddle-opfs)
2022-09-23
21:01
Internal changes to the recover extension towards a step() style interface. (check-in: 73926d5c user: dan tags: recover-extension)
11:40
Fix various compiler warnings in new code on this branch. (check-in: ae49e9ef user: dan tags: recover-extension)
11:30
Merge latest trunk changes into this branch. (check-in: e87fa70a user: dan tags: recover-extension)
2022-09-21
20:24
Reformulate some JS to work around a buggy/broken code transformation in one of the Emscripten-driven code optimizers. (check-in: e1249369 user: stephan tags: fiddle-opfs)
19:51
Put pieces in place for fiddle to support opfs, but more cleanup is required in the sqlite3.js/fiddle connection. bigIntEnabled now defaults to whether the Emscripten's module has bigint enabled. Add wasm-sensible defaults for several SQLITE_ENABLE/OMIT flags in sqlite3-wasm.c. (check-in: 7c7fb753 user: stephan tags: fiddle-opfs)
18:21
Reduced and improved comments on the constraintCompatibleWithOuterJoin() function. (Leaf check-in: 38aaf26e user: drh tags: trunk)
16:21
shell.c.in: when building in fiddle mode, define _POSIX_SOURCE (ifndef) so that emcc's string.h reveals strdup(). (check-in: fb85b269 user: stephan tags: fiddle-opfs)
14:02
Correct mistyped --shrink-memory flag in speedtest1-worker. Minor OPFS proxy cleanups. (check-in: 86e2b55e user: stephan tags: fiddle-opfs)
12:27
Doc cleanups and additions. Add a way for the OPFS async runner to propagate exception text to the calling thread. (check-in: 5c5e8065 user: stephan tags: fiddle-opfs)
12:25
Added some structure to the wasm demo link list. (check-in: 777077c4 user: stephan tags: fiddle-opfs)
09:54
The RIGHT JOIN logic added to version 3.39.0 added a new restriction on the query flattener which resulted in a performance regression for some queries, as documented by forum post 96b9e5709cf47cda. This change removes that restriction (thus restoring performance) and fixes the problem that RIGHT JOIN was having in a different way. (check-in: 501609ed user: drh tags: trunk)
08:41
Add a link to fiddle.html in the wasm test app index.html. (check-in: 96c734c0 user: stephan tags: fiddle-opfs)
08:39
Move fiddle build rules into the wasm-centric build files. Add rule to push wasm bits to the wasm test server. (check-in: 113f8204 user: stephan tags: fiddle-opfs)
00:16
Break out the decision of whether or not a constraint term is usable by an outer join into a subroutine: constraintCompatibleWithOuterJoin(). (Closed-Leaf check-in: c7fbc9b0 user: drh tags: flattener-omit-restriction-29)
2022-09-20
22:19
Do not allow EP_InnerON terms to be used on a outer join. (check-in: f47aa745 user: drh tags: flattener-omit-restriction-29)
21:07
Add new test cases that (current) get an incorrect answer. (check-in: fe5c3773 user: drh tags: flattener-omit-restriction-29)
19:45
New test cases for query flattening when there are ON clauses and outer joins. (check-in: db55387b user: drh tags: flattener-omit-restriction-29)
19:22
Modify the OP_IfNotOpen opcode so that the jump is taken if the cursor is open but was previously set to a NULL row using OP_NullRow. (check-in: 1292d68c user: drh tags: flattener-omit-restriction-29)
18:18
Remove code that has been previously commented out. (check-in: 852b385a user: drh tags: flattener-omit-restriction-29)
17:43
Merge the fuzzcheck fix from trunk into the flattener improvement branch. (check-in: 930a8c15 user: drh tags: flattener-omit-restriction-29)
17:21
Update the fuzz invariant checker to conform to the latest changes in dbsqlfuzz. (check-in: 8d8c1243 user: drh tags: trunk)
16:57
Is the query flattener restriction 29 (do not allow both EP_InnerON and EP_OuterON constraints on the same FROM clause term) really necessary? This branch explores what happens if we omit that restriction. This is an effort to address the performance regression reported by forum post 96b9e5709cf47cda that is caused by flattener restriction 29. (check-in: 19270577 user: drh tags: flattener-omit-restriction-29)
16:20
Correct a too-strict is-opfs-available check. (check-in: 1b5f1b4a user: stephan tags: fiddle-opfs)
16:10
Merge kv-vfs-magic-names branch into fiddle-opfs branch and make some kvvfs-relevant tweaks. (check-in: e3d36dcd user: stephan tags: fiddle-opfs)
14:52
Export the sqlite3_uri_...() family of functions to wasm. (check-in: 72bebc84 user: stephan tags: fiddle-opfs)
14:39
Merge opfs-proxy-atomics branch into the fiddle-opfs branch. (check-in: 25a36920 user: stephan tags: fiddle-opfs)
14:36
When compiled with SQLITE_OS_KV_OPTIONAL, the magic names ":localStorage:" and ":sessionStorage:" are recognized and converted to use the kv-vfs. (Leaf check-in: c5db9262 user: drh tags: kv-vfs-magic-names)
14:21
Remove an obsolete file. (Closed-Leaf check-in: 1e438554 user: stephan tags: opfs-proxy-atomics)
13:25
Speed up de/serialization of func args and return values in the OPFS VFS proxy. (check-in: 5bf235bb user: stephan tags: opfs-proxy-atomics)
10:47
OPFS proxy: remove one sanity-checking-only level of proxy function to shave off a few microseconds. (check-in: b534831f user: stephan tags: opfs-proxy-atomics)
10:11
Remove extraneous result-code SAB slots. Doc additions. (check-in: 88de2071 user: stephan tags: opfs-proxy-atomics)
08:27
An alternative messaging strategy for the OPFS VFS proxy which uses only SharedArrayBuffer and Atomics, instead of worker messages, for communication (only the initial one-time handshake during initialization uses worker messages). It runs speedtest1 approx. 15-20% faster but still 20-ish% slower than WASMFS Edit: further tests showed it to be very close to the same speed as the Worker-message variant, inconsistently faster or slower within a small margin of error. The former impl is easier to understand, though. (check-in: a83ee308 user: stephan tags: opfs-proxy-atomics)
03:31
OPFS VFS: further internal refactoring towards experimenting with a new comms model. (check-in: 5ca412ce user: stephan tags: fiddle-opfs)
01:28
OPFS VFS: moved i/o buffer from per-file to the VFS, and related refactoring, in prep for experimentation with a new inter-worker comms model. (check-in: d4d63e45 user: stephan tags: fiddle-opfs)
2022-09-19
19:25
Clarify comments that describe query flattener restrictions associated with outer joins. No code changes. (check-in: 2647d73b user: drh tags: trunk)
18:22
Further metrics and buffer-copy optimizations in the OPFS proxy, but with little effect. (check-in: d1f1fe6f user: stephan tags: fiddle-opfs)
17:41
Fix a minor comment typo. No changes to code or documentation. (check-in: 8032db4a user: drh tags: trunk)
17:09
Cut the speedtest1 runtime of the OPFS VFS proxy by approximately 3/4ths via xRead/xWrite buffer-copying optimizations. Still slower than the WASMFS impl by approx. 1/5th. (check-in: fb7f2873 user: stephan tags: fiddle-opfs)
14:56
Remove an obsolete file. Update wasmfs build for today's changes. Fix the case that OPFS.xTruncate() is passed a BigInt instead of a Number. (check-in: 97605392 user: stephan tags: fiddle-opfs)
13:44
Add sqlite3_web_vfs_list() to JS API. Corrected OPFS VFS's registering itself as the default VFS. speedtest1-worker now uses the xDelete() of both the default VFS and OPFS, to avoid that it starts up with a persistent OPFS test db (the native app calls unlink(), but that unlink call operates on a different virtual filesystem than the OPFS VFS). (check-in: 2ec7e091 user: stephan tags: fiddle-opfs)
13:16
Merge kv-vfs branch into fiddle-opfs. Adjust various JS APIs and apps to deal with the new method of handling kvvfs. Adjust speedtest1 JS build to include sqlite3-api.js so that it can use kvvfs and opfs VFSes. Permit passing of the vfs as a URL parameter to certain demo/test apps. Milestone: speedtest-worker.html?vfs=opfs runs with the standalone OPFS impl. (check-in: ec09f32f user: stephan tags: fiddle-opfs)
11:47
speedtest1: add --vfs NAME flag and eliminate code duplication in argc size verification for all flags which take a value. (check-in: 281d0986 user: stephan tags: fiddle-opfs)
10:13
Minor doc improvements in demo-123.js. (check-in: 9370ce94 user: stephan tags: fiddle-opfs)
09:58
Generic cleanups in the OPFS VFS proxies. (check-in: 7d5f6adc user: stephan tags: fiddle-opfs)
09:25
Correct OPFS VFS xRead() to copy the result buffer if the result code is SQLITE_IOERR_SHORT_READ. (check-in: 56668f99 user: stephan tags: fiddle-opfs)
05:19
Replace OPFS VFS xSleep() impl with a more efficient one (no Worker round-trip needed). (check-in: b9773f16 user: stephan tags: fiddle-opfs)
03:57
Rename demo-oo1.* to demo-123.* and add demo-123-worker.html, which runs the same demo via a Worker. Doc typo fixes. (check-in: 2e4a005b user: stephan tags: fiddle-opfs)
00:40
Disable build of wasmfs-using components on aarch64 (ARM), as wasmfs won't build there. (check-in: 9a9eeebc user: stephan tags: fiddle-opfs)
2022-09-18
17:59
Remove a NEVER macro in defragmentPage() that dbsqlfuzz discovered can be true. crash-32d9312f145cdce41613573f6431d9a3e439e3d7 (check-in: 90403759 user: drh tags: trunk)
17:32
Numerous cleanups in the JS bits. Removed some now-defunct wasm test files. Expose sqlite3.opfs object containing various OPFS-specific utilities. (check-in: 26e625d0 user: stephan tags: fiddle-opfs)
03:05
Move the OPFS VFS bits back into api/sqlite3-api-opfs.js. Refactor the OPFS VFS init process to use a Promise-returning function which the client must call, as that eliminates any uncertainty about when the VFS (necessarily activated asynchronously) actually becomes available to the client. Rename x-sync-async.* to test-opfs-vfs.* Milestone: first successful test of OPFS without WASMFS. (check-in: b2abf60d user: stephan tags: fiddle-opfs)
02:35
Move the OPFS VFS bits back into api/sqlite3-api-opfs.js. Refactor the OPFS VFS init process to use a Promise-returning function which the client must call, as that eliminates any uncertainty about when the VFS (necessarily activated asynchronously) actually becomes available to the client. (check-in: 1c660970 user: stephan tags: fiddle-opfs)
00:16
Plug OPFS methods in to their sqlite3_vfs/io_methods counterparts. Add URL args to control debug output and running of sanity-checks in the OPFS init code. (check-in: a0e93ed2 user: stephan tags: fiddle-opfs)
2022-09-17
23:47
Correct OPFS xRead() and xWrite() impls and add a very basic sanity test for them. (check-in: cd06cc67 user: stephan tags: fiddle-opfs)
23:29
Implement OPFS xAccess(), albeit with more limited semantics than the VFS API calls for. Add a way for OPFS xDelete() to optionally recursively remove empty dirs left over after deleting a file. (check-in: c342b5d7 user: stephan tags: fiddle-opfs)
21:13
Generic cleanups in the OPFS sync/async proxy. (check-in: f36bddbe user: stephan tags: fiddle-opfs)
20:50
Add the remaining vfs/io_methods wrappers to the OPFS sync/async proxy, but most are not yet tested. (check-in: 44db9132 user: stephan tags: fiddle-opfs)
18:31
Fix an uninitialized variable in the decoder kv-vfs. (Leaf check-in: 354726aa user: drh tags: kv-vfs)
18:29
Include the kv-vfs as an optional VFS on unix builds if the SQLITE_OS_KV_OPTIONAL compile-time option is present. (check-in: 852812d1 user: drh tags: kv-vfs)
17:26
Merge the latest trunk enhancements into the kv-vfs branch. (check-in: 37c7ca25 user: drh tags: kv-vfs)
15:08

2022-09-16
20:16
Merge kv-vfs branch into fiddle-opfs branch. Adjust speedtest1 --size flags to account for new size limit. (check-in: afb79050 user: stephan tags: fiddle-opfs)
15:19
Corrections to the xRead method for databases in the os_kv.c VFS so that it correctly reads the header, and thus avoids unnecessary cache flushes. This changes also includes an optimization to the header read logic. (check-in: ef54961c user: drh tags: kv-vfs)
12:49
When calculating kvvfs sessionStorage/localStorage size, multiply it by 2 to account for JS using 16-bit characters. (check-in: 52d1b185 user: stephan tags: fiddle-opfs)
11:45
Merge kv-vfs branch into fiddle-opfs branch for [21915af560b1|synchronous=off fix]. Remove some duplicate debug output in OPFS test code. (check-in: 13899bb9 user: stephan tags: fiddle-opfs)
11:37
Fix os_kv.c so that it uses SQLITE_FCNTL_SYNC and hence works even with PRAGMA synchronous=OFF. (check-in: 21915af5 user: drh tags: kv-vfs)
02:30
Add batch-runner-kvvfs.html, a kvvfs-specific build of batch-runner.html. Reduce the speedtest1 --size X value for the batch list generation to 5 so that the kvvfs batch runner can handle it. (check-in: d8df2592 user: stephan tags: fiddle-opfs)
02:28
Remove --nosync flag from speedtest1-kvvfs.html, as that seems to be the trigger for the 'no such table: z1' error. That app now warns if that flag is passed to it via URL args. (check-in: ad0677e8 user: stephan tags: fiddle-opfs)
01:08
Pull the src/os_kv.c part of [13839759f8f4] into the kv-vfs branch. (check-in: e3344499 user: stephan tags: kv-vfs)
01:05
Add return value checks to kvstorageWrite(), necessary for recognizing storage-full errors in the JS binding. speedtest1-kvvfs.html runs successfully on localStorage with --size 1 to 6 and starts failing with storage shortage at --size 7. (check-in: 13839759 user: stephan tags: fiddle-opfs)
2022-09-15
06:42
More work on the synchronous OPFS experimentation. Numerous wasm/js build tweaks. Add speeedtest-wasmfs.html, the wasmfs/opfs counterpart of speedtest1.html. (check-in: 00ee49a3 user: stephan tags: fiddle-opfs)
03:54
Fix windows builds of recover extension. (check-in: abcbb6ab user: dan tags: recover-extension)
03:16
Remove some stale comments. Get scratchpad-opfs-worker2.js running again in prep for reuse in experimenting with the OPFS all-synchronous API. (check-in: 4cbbd370 user: stephan tags: fiddle-opfs)
03:09
Split wasmfs-enabled build of sqlite3.js/wasm into sqlite3-wasmfs.js/wasm, as enabling wasmfs breaks all tests/demos which run from a Worker thread. (check-in: 08476f3c user: stephan tags: fiddle-opfs)
02:27
Clean up some JS documentation. (check-in: 925fdbfc user: stephan tags: fiddle-opfs)

19:27
Add/apply various kvvfs-specific utility APIs to the JS layer to assist in testing and analysis. Correct a backwards default arg check for sqlite3ApiBootstrap(). Add exports for sqlite3_db_handle(), sqlite3_file_control(), and the SQLITE_FCNTL_xxx enum. (check-in: 0d789618 user: stephan tags: fiddle-opfs)
18:08
Add tests. Deal issues surrounding aborting recovery from within the SQL callback, and avoiding the pending-byte page. (check-in: 4e97dd31 user: dan tags: recover-extension)
2022-09-12
22:27
Get testing1.js working with a kvvfs build. (check-in: 333a4572 user: stephan tags: fiddle-opfs)
20:21
Remove an extraneous key-copy op in the EM_JS impl of kvstorageDelete(). (check-in: 1c5aeee4 user: stephan tags: kv-vfs)
20:18
Merge kv-vfs branch into fiddle-opfs and add speedtest1-kvvfs.html test app (which currently fails early on). (check-in: 8b1608a9 user: stephan tags: fiddle-opfs)
20:02
Fix some problems with handling corrupt database in the recovery extension. (check-in: ed318be8 user: dan tags: recover-extension)

19:23
More tests for the recover module. (check-in: 37fb093b user: dan tags: recover-extension)
18:10
Fix a debugging/testing edit in the previous check-in. (check-in: 6fc8d34c user: drh tags: kv-vfs)
17:59
Add sqlite3.oo1.DB.clearKvvfsStorage(). Add controls to kvvfs1.js demo to reset and query the db without requiring the dev console. (check-in: d845c6c2 user: stephan tags: fiddle-opfs)
17:44
Faster text decoder for kv_os.c. (check-in: 3354a2ed user: drh tags: kv-vfs)
16:09
Merge kv-vfs branch into fiddle-opfs branch to add kvvfs-based wasm build and demo. (check-in: a7d8b26a user: stephan tags: fiddle-opfs)

New run-time options to the speed-check.sh script. (check-in: ff46bc9d user: drh tags: trunk)
15:59
Fix uninitialized variable in rollback-journal processing in os_kv.c (check-in: e49682c5 user: drh tags: kv-vfs)
13:05
Resolve missing kvvfs JS test: sqlite3_initialize() must be called by the client in this build. Add basic sanity test of kvvfs using sessionStorage(). (check-in: 250a935a user: stephan tags: kv-vfs)
12:41
Fix the amalgamation so that it builds with the standard unix backend again. (check-in: 0adf158f user: drh tags: kv-vfs)
12:39
Initial build of kvvfs in wasm. It loads but cannot find the VFS for as-yet-unknown reasons (sqlite3 shell works fine), and most APIs throw "null function or function signature mismatch" from deep within wasm, presumably as a side effect of the "missing" VFS. (check-in: 1a2f24a0 user: stephan tags: kv-vfs)
2022-09-11
16:59
Minor cleanups and documentation in the wasm pieces. (check-in: 4e6ce329 user: stephan tags: fiddle-opfs)

2022-09-10
20:01
Rework recover extension code for readability. (check-in: 1a254096 user: dan tags: recover-extension)
18:38
Improved comments in os_kv.c. Better names for the key/value name spaces. (check-in: 8e1652a3 user: drh tags: kv-vfs)
18:20
Move the vfskv.c extension to src/os_kv.c and make it part of the amalgamation, activated if and only if SQLITE_OS_KV is true. (check-in: f6632e69 user: drh tags: kv-vfs)
13:50
Enhance the b-tree page sorting code to ensure that sqlite3PagerRekey() never overloads a page number and uses only the PENDING_BYTE page for temporary storage. (Leaf check-in: aa6a5b72 user: dan tags: branch-3.39)
2022-09-09
20:44
Further fixes to comments in sqlite3recover.h. Also rework some data structures in sqlite3recover.c. (check-in: 599d1f8e user: dan tags: recover-extension)
17:50
Fix harmless compiler warning seen with MSVC. (check-in: 73c4c68d user: mistachkin tags: trunk)
16:25
Handle recovery of virtual tables by recovering each shadow table individually, then writing the CREATE VIRTUAL TABLE statement directly into the sqlite_schema table. (check-in: 5f2d5ccd user: dan tags: recover-extension)
16:16
Database must be named either "local" or "session". Each has a distinct namespace. (check-in: c8e41279 user: drh tags: kv-vfs)
14:22
Separate sqlite3_io_methods objects for database files and journals. (check-in: 74fbf6c2 user: drh tags: kv-vfs)
11:41
Simple reading and writing now works. (check-in: 00845ac9 user: drh tags: kv-vfs)
05:39
Remove a reference to a completed TODO. (check-in: 757ad696 user: stephan tags: fiddle-opfs)
04:50
speedtest1 wasm: add a link in the worker variant which launches the main-thread variant with the selected CLI flags. Append collected stdout/stderr to the main-thread page after execution is finished to avoid having to open the dev tools (which inexplicably slows down wasm execution). (check-in: 02709ee2 user: stephan tags: fiddle-opfs)
2022-09-08
21:43
Update comments in sqlite3recover.h. (check-in: 14164047 user: dan tags: recover-extension)
21:33

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.

Do not allow an ON clause to references tables to its right if there is a RIGHT or FULL join anywhere in the query.

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)

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)

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)

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)

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)

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)

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)

Transitive equality constriants do not work on a RIGHT JOIN, since the right-hand side might be a non-matched row. (check-in: 0f96810b user: drh tags: trunk)
19:50
Walk back the optimization from check-in [cc458317bd77046c] that tries to reuse the same ephemeral cursor of a list subquery when that subquery is reused, as it does not work in cases where the list subquery is used both for lookups and for scans. (check-in: 12ee29d6 user: drh tags: trunk)
17:45
Defer generating WHERE clause constraints for a RIGHT JOIN until after the ON-clause processing for the RIGHT JOIN has done its own row elimination. This fixes and incorrect output from some RIGHT JOINs that was identified by forum post 41cc3851d864c5e6. (check-in: 238d9c24 user: drh tags: trunk)

Preliminary code to support RIGHT JOIN. Everything seems to work, except that the code to compute the unmatched rows for the RIGHT JOIN has not yet been added, so the result of a RIGHT JOIN is currently the same as an INNER JOIN. (check-in: 415abd67 user: drh tags: right-join)
17:01
Enhance the sqlite_dbpage fix at check-in 642a0b4752743 from about a month ago such that it still takes a transaction on all attached databases, but it only starts a read transaction for read-only operations, rather than starting a write transaction for everything.

The ".testctrl optimizations 0x400000" command disables the generation of OP_ReleaseReg opcodes. OP_ReleaseReg opcodes are usually only generated for SQLITE_DEBUG builds and are used to verify that registers are descoped propertly. But they can get in the way of code understanding when studying bytecode dumps. So this new optimization setting is provided to temporarily turn OP_ReleaseReg opcodes off.

Fix for the problem identified in forum post 0cd8e058bf: When evaluating an multi-index OR, do not push down auxiliary WHERE clause terms that involve subqueries into the OR-subqueries. Otherwise, the covering-index optimizer might convert table-references into index-references for the particular OR index that is active for the branch in which the subquery subroutine is coded, and those index-references will not work if the subquery subroutine is invoked from a different OR branch that uses a different index.

If neither macro is defined, then assert() statement do generate code but VVA() statements do not, and that is a deadly combination. forum post 858dee399e (check-in: d9f814a6 user: drh tags: trunk)

00:25
Fixes to the version of "varsep" group_concat so that (1) it builds under separate compilation and (2) omits tabs in source code and (3) runs faster than trunk. This variant of the group_concat_varsep branch might be preferred over the tip because it preserves (undocumented) legacy behavior about the position of separators relative to terms. (check-in: 04399cf9 user: drh tags: group_concat-fix-legacy)

2021-09-27
17:11
Have the dbstat virtual table take a copy of each page buffer that it traverses instead of just a reference to the page-cache object. This avoids problems if an error causes transaction rollback while a dbstat cursor is open. dbsqlfuzz crash-417224040fee04f0f0e62b70265c518893b08769. (check-in: 6ab25f8b user: dan tags: trunk)

Dbsqlfuzz (a097eaad43c3c845b236126df92fb49b25449b0c) found a way to reach the assert() that was added to sqlite3_declare_vtab() by [eb94f4a8174436b1]. This check-in fixes the problem. (check-in: 857d26a6 user: drh tags: trunk)

Ensure that sqlite_stat1 and sqlite_stat4 are ordinary tables (not views or virtual tables) before trying to load them (dbsqlfuzz bc02a0cde82dee801a8d6f653d2831680f87dca1). This prevents sqlite3_declare_vtab() from running with db->init.busy turned on. Even so, enhance sqlite3_declare_vtab() to be able to deal with db->init.busy being on, in case there are undiscovered paths to that state. Each of these two changes are independently sufficient to prevent the problem fixed by the previous check-in [c7560c1329965ab5] but there is no harm in keeping that third layer of protection in place.

For ALTER TABLE RENAME COLUMN, do not try to filter virtual tables out of calls to sqlite_rename_column(). Let the function filter them itself. The WHERE clause can mistakenly let virtual tables through if the sqlite_schema table is corrupt. The sqlite_rename_column() function must deal with them.

One of the optimizations of check-in [de9c86c9e4cdb34f] does not work for terms originating in the ON/USING clause, as demonstrated by forum post 6cf3bb457c3f4685. This check-in disables that optimization for ON/USING terms. Also improve the TreeView display for the resulting "true"/"false" nodes to show that they originate from the ON/USING clause. Add a testcase() to the other optimization to show that it can still be used for ON/USING terms. (check-in: 1f679604 user: drh tags: trunk)

This is another alternative fix to the covering index on WHERE_MULTI_OR in a LEFT JOIN problem that is fixed on trunk nearby. In this alternative, covering indexes are simply disabled for WHERE_MULTI_OR on a LEFT JOIN. This might have run-time impact on some obscure queries.

This is an alternative fix to the covering index on WHERE_MULTI_OR in a LEFT JOIN problem that is fixed nearby.

An index on the expression "likely(X)" should store the true value of X, even if X is a real number with no fractional part. The optimization of storing some REAL indexed values as INT (see [10d851353c2abead]) should be omitted for index columns that are expressions. Forum post 3b940c437a.
