Fix a base64 decode bug. Provide for convenient inclusion of extension(s) built into the CLI, to simplify testing and for its own sake. Improve comments. Cure collision between base64.c and base85.c when both are in the same translation unit. (check-in: 07543d23 user: larrybr tags: base_convert)
2022-11-20
15:30
Remove check for WASM_WASI macro when detecting wasi compilation mode, as that macro is project-specific. Rely only on __wasi__ (exposed by clang) to detect wasi compilation mode. (check-in: d469ac0c user: stephan tags: wasi-patches)
05:47
js dist: account for a file rename in the previous checkin. (check-in: 469f9011 user: stephan tags: trunk)

05:26
Add build of sqlite3.mjs (ES6 module), add a test app for it, and include it in the dist build. (check-in: 2e783670 user: stephan tags: trunk)
02:58
Integrate a custom preprocessor to the JS build process to facilitate creation of both vanilla JS and ES6 Module builds from the same source files. There is still some build-level reworking pending to make an ESM build a first-class deliverable. (check-in: 10c723d9 user: stephan tags: trunk)
02:51
More work towards creation of a ES6 JS module. (Closed-Leaf check-in: 6b826e70 user: stephan tags: js-cpp)

2022-11-18

17:50
Add the SQLITE_DBCONFIG_LENIENT_JSON configuration option. Modify the built-in JSON routines such that when this setting is active, arguments that that ought to be JSON but still give a reasonable result (ex: NULL) rather than raising an error. (Leaf check-in: 186db57d user: drh tags: lenient-json)
15:22
shell.c.in: on non-Windows platforms, check for $XDG_CONFIG_HOME/sqlite3/sqliterc before ~/.sqliterc, per request in forum post 7a16582b1e403c81. (check-in: 17065d09 user: stephan tags: trunk)
02:29
Replace use of cpp with the fit-to-purpose c-pp to avoid cpp's C-centric/JS-unfriendly quirks. (check-in: 49d70f07 user: stephan tags: js-cpp)

13:58
Split out the documentation for sqlite3_value_encoding() into its own page and make it clear that this interface is intended for testing and debugging only. Forum thread c9f445453da950ad. Comment changes only - no changes to code. (check-in: 9048a766 user: drh tags: trunk)
01:24
Raise an error if an attempt is made to compile the CLI with the SQLITE_OMIT_COMPLETE option, since sqlite3_complete() really is necessary for the CLI to operate sanely. (check-in: a119a9e2 user: drh tags: trunk)
2022-11-16
21:52
Change a self.X JS reference to X to account for a symbol resolution discrepancy between vanilla JS and ES6 modules, as explained in forum post 801d8f77e5115141. (check-in: 0590de4d user: stephan tags: trunk)

18:57
Change the fake_big_file test command so that it fails for files larger than 2MB on Windows, as we have observed that Window10 will sometimes bluescreen when operating on very large sparse files. (check-in: d39ffd2a user: drh tags: trunk)
17:48
Avoid running bigsort.test with SQLITE_DEBUG builds. The assert() statements added in [7c96a56] make it too slow. (check-in: fa68dd89 user: dan tags: trunk)

2022-11-12
17:17
Disable the ability to change the schema_version cookie when SQLITE_DBCONFIG_DEFENSIVE mode is enabled. This is a security enhancement inspired by the question in forum post 2b9cc3dae1f1e5f6. (check-in: 1d81381e user: drh tags: trunk)
2022-11-10
23:10
Remove unnecessary tabs in the ChaCha20 implementation. Forum post 0cdce5db8c. (check-in: b7179efb user: drh tags: trunk)
19:19
Avoid returning SQLITE_SCHEMA if the first query run on a connection is "SELECT nosuchcolumn" or similar. Forum post c1798f77ef (Closed-Leaf check-in: d31c019f user: dan tags: schema-error-fix)
13:22
Automatically relinquish implicitly-acquired OPFS file locks during VFS idle time in an attempt to help alleviate cross-tab locking contention like that described in forum post 58a377083cd24a. (check-in: 8daf24ff user: stephan tags: trunk)
13:14
Rework automatically acquired OPFS locks to be released during idle time. This eliminates the performance hit reported in [46304ba057707c]. (Closed-Leaf check-in: a7fe91af user: stephan tags: opfs-lock-without-xlock)
11:35
OPFS: if an op which needs a lock is called when no lock has been obtained, automatically lock it at the start of the op and unlock it at the end of that op. This is an attempt to alleviate the cross-tab contention described in forum post 58a377083cd24a but it increases speedtest1 run time by approximately 4x. Perhaps auto-lock can be combined with the older idle-time-based auto-unlock to unlock such locks (but not those from xLock()) to improve this? (check-in: 46304ba0 user: stephan tags: opfs-lock-without-xlock)

2022-11-06
17:19
The recoverAssertMutexHeld() function is for testing and verification only and should be a harmless no-op for production builds. [forum/forumpost/b4f2c7d402|Forum post b4f2c7d402]. (check-in: d7550471 user: drh tags: trunk)
