* wasm refactoring part 2 of (apparently) 2: moved ext/fiddle/... into ↵stephan2022-08-10
| | | | | ext/wasm and restructured the core API-related parts of the JS/WASM considerably. FossilOrigin-Name: 27f9da4eaaff39d1d58e9ffef7ddccf1e41b3726914f754b920e3e1fb572cba6
* wasm/fiddle refactoring part 1 of N: move fiddle app from ext/fiddle to ↵stephan2022-08-10
| | | | | ext/wasm/fiddle, which only contains files intended to be pushed to the live site. Disabled build of the non-fiddle wasm parts, pending a later step of the refactoring. FossilOrigin-Name: fb4eb93080288b60815be14afd7ddbbca470ce363fa3735352ea9a558fef583e
* wasm: corrected the isInt32() check to account for negative values.stephan2022-06-25

* wasm: added bindings for sqlite3_extended_result_codes(), sqlite3_open_v2(), ↵stephan2022-06-25
| | | | | and the SQLITE_OPEN_... flags. FossilOrigin-Name: ac876ab9913332c9a5e3045824bf92a2501707aecfb13906d5c280302d9878a9
* wasm: lots of doc additions and refactoring. Refactored the WASM memory heap ↵stephan2022-06-25
| | | | | usage to hopefully eventually account for a runtime-growable heap. Differentiate between supported TypedArray types for input SQL strings vs binding/fetching blobs. Might (untested) have implemented the ability to bind UtfNNArray values as blobs, where NN is one of 16 or 32. FossilOrigin-Name: e10d57dfbaa672a3a4cbfd9a9209552c3bde15cc75af838690ca412fd182066a
* wasm: added utility C code to generate a JSON-format "enum" of the numerous ↵stephan2022-06-25
| | | | | SQLITE_xyz constants so that we do not risk those getting out of sync in the JS code. Renamed initSqlite3Module to sqlite3InitModule. Cleanups in the TypedArray handling. FossilOrigin-Name: 778062e3b415dca5104eee398950741b6dbb9d4bdf7c998eef18371a42669946
* wasm: eliminated the need for Stmt objects to keep ahold of memory allocated ↵stephan2022-06-25
| | | | | for bound strings and blobs. Added alternate string/blob bind impls which are hypothetically more efficient but not yet proven to be so. FossilOrigin-Name: da1d3151a440567f34a2f6c0b2bfc2e9fab81c256cc361c9ce7b46f2c23a2aa8
* wasm: eliminated the dependency on the deprecated emcc-provided allocate() ↵stephan2022-06-25
| | | | | function. Adjacent cleanups in blob binding. FossilOrigin-Name: 140618b212e3aa9ff2df20f22af846a1c4c5ffaeefd84330446f61362b39a8f1
* wasm: corrected the propagation of text/blob values via UDFs. DB.exec()'s ↵stephan2022-06-25
| | | | | sql may now be an array of strings which get concatenated together before passing it on to sqlite3_prepare_v2(). DB.exec()'s callback now applies to the first statement which has result columns instead of only the first statement. Fixed a precedence but which caused isInt32() to report false positives.

* wasm binding: consolidated the two sqlite3_prepare_v2() bindings behind a ↵stephan2022-06-25
| | | | | single dispathcer. Various internal cleanups and refactoring. Branched because trunk is in pencils-down mode for pending 3.39 release. FossilOrigin-Name: ab3e50dab4d71557ab5d179bbd6caf7fb61ab7c51dffc8e4714441c189ce3e5c
* fiddle: minor style tweaks, including using swapped colors for the ↵stephan2022-06-10
| | | | | input/output fields to help (hopefully) reduce the "which field is which?" dissonance. FossilOrigin-Name: e25dad868f9ef2c7847319c9f6f106999ba8b0a3e09ed9edfbd25e8fc6f3c10e

* shell: in WASM mode, permit ATTACH because the filesystem is a virtual ↵stephan2022-06-06
| | | | | sandbox and ATTACH can be used to provide more import/export options. Minor doc updates in sqlite3-api.js. FossilOrigin-Name: f28de5b726999b913b442fa51355d020ba1f1662d2f7978380623c16438eb238
* fiddle: added another UI element to the list of those which are disabled ↵stephan2022-06-01
| | | | | during long-running activities. Added DB.close() binding to the Worker-based wasm binding. FossilOrigin-Name: 5933163ed1a8f996e81023c7c5822655dc6411d30016f37fe8863f760530dc5b
* The Worker-specific variants of the most significant DB-class JS bindings ↵stephan2022-06-01

* Initial proof of concept code for a JavaScript binding which runs in the ↵stephan2022-06-01
| | | | | main window thread but acts on a db handle running in a Worker thread. Expanded the DB.exec() and DB() constructor to simplify certain use cases. FossilOrigin-Name: d9efe3e92d1c95aee6f5ae37a8ba28d8cf4891d746744ce4aa2464f766821a0b
* Initial bits for a JS API variant in which the client operates in the main ↵stephan2022-06-01

* Updated the wasm builds to generate gzip'ed copies of relevant files to take ↵stephan2022-05-31
| | | | | advantage of althttpd's new capability of substituting gzip files in place of requested files. This cuts over-the-wire size of the fiddle app by more than half. FossilOrigin-Name: 40925585f1dab25babac46a0f4b9d633315110b8d4ccb04cc6df115d167e5ab4
* fiddle: changed the internal key of the session/local storage to avoid ↵stephan2022-05-28
| | | | | conflicts with the pikchr fiddle app (which is derived from this one) when running from the same HTTP origin as an instance of that app in a dev environment. FossilOrigin-Name: fd668da5ccf037c2ad8e61e381dd1eb398a8deab42a00593e551c30bd176890d

* fiddle: added an option to completely wipe/reset the db. The Options area ↵stephan2022-05-27
| | | | | 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. FossilOrigin-Name: d100283e378f2d8e353399848184a4ab8ccf6316218fffc28b90a656cf81c279

| * fiddle: added support for exporting (downloading) the current db file. To do ↵stephan2022-05-24
| | | | | | | | | | 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. FossilOrigin-Name: 7c7fd34c8a05832a3973aaffe696250cb4d2a0b1646c9bfbe83970daf33cd817

* WASM: removed the in64-related bindings, as MDN says that calling a wasm ↵stephan2022-05-23
| | | | | 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).
