2018-10-04Dual-build wasm and asm.js olmDavid Baker
2018-09-25Another day, another interfaceDavid Baker
Change the interface again, hopefully this time a bit more normal. Now we wrap the emscripten module completely and just expose the high level objects. The olm library export is now imported as normal (ie. returns a module rather than a function returning a module) but has an `init` method which *must* be called. This returns a promise which resolves when the module is ready. It also rejects if the module failed to set up, unlike before (and unlike the promise-not-a-promise that emscripten returns). Generally catch failures to init the module.
2018-09-21Make OLM_OPTIONS work againDavid Baker
The closure compiler was just renaming the variable so it never would have picked them up. Make it an extern so it knows what to do.
2018-09-21WebAssembly support!David Baker
Quite a lot going on in this PR: * Updates to support recent emscripten, switching to WASM which is now the default * Use emscripten's MODULARIZE option rather than wrapping it ourself, since doing so in pre-post js doesn't work anymore. * Most changes are moving the emscripten runtime functions to top-level calls rather than in the Module object. * Get rid of duplicated NULL_BYTE_PADDING_LENGTH * Fix ciphertext_length used without being declared * Fix things that caused the closure compiler to error, eg. using OLM_OPTIONS without a declaration. * Wait until module is inited to do OLM_ERROR = olm_error() The main BREAKING CHANGE here is that the module now needs to initialise asyncronously (because it has to load the wasm file). require()ing olm now gives a function which needs to be called to create an instance. The resulting object has a promise-like then() method that can be used to detect when the module is ready. (We could use MODULARIZE_INSTANCE to return the module directly as before, rather than the function, but then we don't get the .then() method).
2016-12-14Let apps override emscripten settingsRichard van der Hoff
Read settings from OLM_OPTIONS to allow apps to configure some options. In particular, this is useful for setting the heap size.
2016-12-12Better handling of exceptions during loadingRichard van der Hoff
If we get an exception during load, don't define half of window.Olm (which confuses apps). This is a partial fix to https://github.com/vector-im/riot-web/issues/2726.
