13:46
Fix the ".dump" command in the CLI so that it is more rebust against corrupt database files. At the same time, enhance the sqlite3_strglob() and sqlite3_strlike() interfaces so that they will do sensible things with NULL string pointers. (check-in: 681c85ef user: drh tags: branch-3.39)

2022-10-07
19:11
Fix a problem causing the seek-scan optimization to skip over valid rows that could occur when it is used with expressions of the form (a IN (?,?..) AND b >= ?). dbsqlfuzz ab1db6dc0efb04cba1cd3431ee6da4894fdc4520. (check-in: b6be4ce6 user: drh tags: branch-3.39)

Fix a problem that occurred when using a bloom filter to optimize an (ipk = ?) lookup in the case where the RHS of the expression is a TEXT value. First reported by forum post f61a8b7053. (check-in: dc01d9d8 user: drh tags: branch-3.39)
17:58
Increase the version number to 3.39.5. (check-in: 8eb0048e user: drh tags: branch-3.39)

Remove a NEVER macro in defragmentPage() that dbsqlfuzz discovered can be true. crash-32d9312f145cdce41613573f6431d9a3e439e3d7 (check-in: a4342fc0 user: drh tags: branch-3.39)
2022-09-27
02:04

2022-09-16
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)
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)
01:08
Pull the src/os_kv.c part of [13839759f8f4] into the kv-vfs branch. (check-in: e3344499 user: stephan tags: kv-vfs)

Fix uninitialized variable in rollback-journal processing in os_kv.c (check-in: e49682c5 user: drh tags: kv-vfs)
13:05

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)

02:43
Initial prototype impls of write/delete-key ops for the pending kvvfs which use sessionStorage or localStorage for db page storage. read-key op is pending. (check-in: a4bd96f5 user: stephan tags: fiddle-opfs)
2022-09-10
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. (check-in: aa6a5b72 user: dan tags: branch-3.39)
2022-09-09
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
21:33
Make use of the --big-transactions flag in the speedtest1 JS apps. (check-in: f2846dcb user: stephan tags: fiddle-opfs)
21:09
Add speedtest1 --big-transactions flag to cause its large tests which rely on implicit transactions to be wrapped in BEGIN/COMMIT, per /chat discussion. Added to support of the WASMFS build, which slows down significantly when thousands of implicit transactions are used. (check-in: 51395c00 user: stephan tags: fiddle-opfs)
20:04
Minor build cleanups and tweaks in the speedtest1 wasm apps. (check-in: 5240fb4d user: stephan tags: fiddle-opfs)
19:53

17:12
Compiles and loads as an extension. Starts to run but quickly hits issues. (check-in: 2e38726f user: drh tags: kv-vfs)
16:27
Compiles without error, but untested. (check-in: a329939c user: drh tags: kv-vfs)
15:48
Code snapshot. Completely untested. Probably does not compile. (check-in: 51e26769 user: drh tags: kv-vfs)
15:30
Add speedtest1-worker.html, an interactive Worker-thread variant of speedtest1.html. Add ext/wasm/index.html to act as a gateway to the various test pages. (check-in: f16c68ee user: stephan tags: fiddle-opfs)
2022-09-07
20:14
Enhance an assert() to impose for tighter constraints on the operation of pcache. (check-in: 461511cc user: drh tags: branch-3.39)
20:11
Enhance an assert() to impose for tighter constraints on the operation of pcache. (check-in: 42105eb4 user: drh tags: trunk)
19:58
Fix the windows build so that it works with -DSQLITE_OMIT_AUTOINIT. (check-in: 1662eb07 user: drh tags: branch-3.39)
19:28
An improved technique for ensuring that the Rekey() operation does not overwrite an existing page number. This approach does not change the semantics of the underlying pluggable pcache and it is easier to prove correct. This replaces the changes at [aadd38f99a3e5abc] and [81cff9f1955874aa]. (check-in: 7dbddde7 user: drh tags: trunk)
17:29
Non-working code towards a VFS for text key/value storage. (check-in: f9c89ee8 user: drh tags: kv-vfs)
2022-09-06
23:04
Add a note about Emscripten's -sSINGLE_FILE flag, why it would be nice, and why we can't use it. (check-in: 5ea06236 user: stephan tags: fiddle-opfs)
20:17
Get speedtest1.js working with WASMFS/OPFS. (check-in: 40e60f57 user: stephan tags: fiddle-opfs)
16:47
Initial build of speedtest1.wasm and speedtest1.html with which to run it. (check-in: 4441535e user: stephan tags: fiddle-opfs)
16:35
Minor internal doc clarifications. (check-in: 09796cc2 user: stephan tags: fiddle-opfs)
09:59
Merge trunk into fiddle-opfs branch. (check-in: 7f76eaec user: stephan tags: fiddle-opfs)
2022-09-05
22:54
Add the tool/omittest-msvc.tcl script that will try to build using MSVC using various compile-time options, to ensure that the compile-time options all build without errors. (check-in: 6b00ecb5 user: drh tags: trunk)
22:53
Get the tool/omittest-msvc.tcl script working. (Closed-Leaf check-in: 82b89f8a user: drh tags: msvc-omit-test)
20:42
Add a prototype for a script, similar to tool/omittest.tcl, that is designed to test builds using MSVC to ensure they work with various OMIT options. (check-in: b1e37a0b user: drh tags: msvc-omit-test)
18:17
Fix the windows build so that it works with -DSQLITE_OMIT_AUTOINIT. (check-in: f74a5ea8 user: drh tags: trunk)
