Not a lot of attention has been paid to dealing with conflicts of symbols
between crates and different `#[wasm_bindgen]` blocks. This commit starts to fix
this issue by unblocking #486 which first ran into this. Currently there's a bug
where if two independent crates bind the same JS API they'll generate the same
symbol which causes conflicts for things like LTO or linking in general.
This commit starts to add a "salt" to all symbols generated by `wasm-bindgen`
(these are all transparent to the user) to ensure that each crate's invocations
are kept apart from one another and using the correct bindings.
This test fails on my system. As previously decided, until we can
figure out a better solution for this issue, for now we just check
to make sure the output is a non-empty string.
* webidl: Remove exact-output tests
These have not been as effective, nor as easy to write and maintain, as the
project()-based integration tests.
* tests: Move webidl tests into the webidl crate's test suite
* Create a new `web-sys` crate
This will eventually contain all the WebIDL-generated bindings to Web APIs.
* ci: Test the new `web-sys` crate in CI
* web-sys: Add a small README
* web-sys: Vendor all the WebIDL files from mozilla-central
* backend: Add a pass to remove AST items that use undefined imports
This is necessary for the WebIDL frontend, which can't translate many WebIDL
constructs into equivalent wasm-bindgen AST things yet. It lets us make
incremental progress: we can generate bindings to methods we can support right
now even though there might be methods on the same interface that we can't
support yet.
* webidl: Add a bunch of missing semicolons
* webidl: Make parsing private
It was only `pub` so that we could test it, but we ended up moving towards
integration tests rather than unit tests that assert particular ASTs are parsed
from WebIDL files.
* webidl: Remove uses of undefined import types
* test-project-builder: Build projects in "very verbose" mode
This helps for debugging failing WebIDL-related tests.
* test-project-builder: Add more profiling timers
* test-project-builder: Detect when webpack-dev-server fails
Instead of going into an infinite loop, detect when webpack-dev-server fails to
start up and early exit the test.
* webidl: Specify version for dev-dependency on wasm-bindgen-backend
Instead of only a relative path.
* guide: Add section about contributing to `web-sys`
* WIP enable Event.webidl
Still need to fix and finish the test.
* Update expected webidl output
* Start out a test's status as incomplete
That way if we don't fill it in the error message doesn't look quite so bizarre
* Fix onerror function in headless mode
Otherwise we don't see any output!
* Fix package.json/node_modules handling in project generation
Make sure these are looked up in the git project root rather than the crate root
* Avoid logging body text
This was meant for debugging and is otherwise pretty noisy
* Fix a relative path
* More expected test fixes
* Fix a typo
* test-project-builder: Allow asynchronous tests
* webidl: Convert [Unforgeable] attributes into `#[wasm_bindgen(structural)]`
Fixes#432
* test-project-builder: Print generated WebIDL bindings for debugging purposes
Helps debug bad WebIDL bindings generation inside tests.
* When we can't find a descriptor, say which one can't be found
This helps when debugging things that need to become structural.
* web-sys: Test bindings for Event
* ci: Use `--manifest-path dir` instead of `cd dir && ...`
* web-sys: Just move .webidl files isntead of symlinking to enable them
* tests: Polyfill Array.prototype.values for older browsers in CI
* test-project-builder: Don't panic on poisoned headless test mutex
We only use it to serialize headless tests so that we don't try to bind the port
concurrently. Its OK to run another headless test if an earlier one panicked.
* JsValue: Add {is,as}_{object,function} methods
Allows dynamically casting values to `js::Object` and `js::Function`.
* tidy: Fix whitespace and missing semicolons
* Allow for dynamic feature detection of methods
If we create bindings to a method that doesn't exist in this implementation,
then it shouldn't fail until if/when we actually try and invoke that missing
method.
* tests: Do feature detection in Array.prototype.values test
* Add JsValue::{is_string, as_js_string} methods
And document all the cast/convert/check methods for js value.
* eslint: allow backtick string literals
* Only generate a fallback import function for non-structural imports
* binding for Date.prototype.getHours()
* binding for Date.prototype.getMilliseconds()
* binding for Date.prototype.getMinutes()
* binding for Date.prototype.getMonth()
* binding for Date.prototype.getSeconds()
* binding for Date.prototype.getTime()
* binding for Date.parse()
The WebIDL-based -sys crate will also use this, but I want its tests to be a
separate suite that we can run separately and in parallel in CI. Therefore, this
testing infrastructure code needs to be share-able between them :)
* tests: Add newlines between impl methods for Project
* WIP headless browser testing with geckodriver and selenium
* Get some more of headless testing working
* Extract `console.log` invocations and print them from the console
* Ship the error message from an exception from the browser back to the command
line
* Cleanup some "if headless" and `else` branches
* Fix killing `webpack-dev-server` in the background with `--watch-stdin`
* Fix path appending logic for Windows
* Always log logs/errors in headless mode
* Install Firefox on Travis
* Don't duplicate full test suite with `yarn`
No need to run that many tests, we should be able to get by with a smoke test
that it just works.
* headless tests: Move `run-headless.js` to its own file and `include_str!` it
* Run `rustfmt` on `tests/all/main.rs`
* guide: Add note about headless browser tests and configuration
* test: Log WASM_BINDGEN_FIREFOX_BIN_PATH in run-headless.js
* TEMP only run add_headless test in CI
* Add more logging to headless testing
* Allow headless tests to run for 60 seconds before timeout
* TEMP add logging to add_headless test
* Fix headless browser tests
* Another attempt to fix Travis
* More attempts at debugging
* Fix more merge conflicts
* Touch up an error message
* Fixup travis again
* Enable all travis tests again
* Test everything on AppVeyor
* Reorganize Travis configuration
* Add a `JOB` env var descriptor to all matrix entries. Not used anywhere but is
useful when viewing the whole build on Travis's web interface.
* Reorganize where builds are located, moving slow builds first and fast ones
last.
* Change checking the CLI builds from `cargo build` to `cargo check`
* Use YAML references to reduce some duplication
* Print some more timing statistics for each test
* Extract `Project` helper in tests to a module
This'll help make it a bit more extensible over time. At the same time the
methods are also slightly reorganized to read more clearly from top to bottom.
* Migrate all tests away from Webpack
Wepback can take a significant amount of time to execute and when it's
multiplied by hundreds of tests that adds up really quickly! After investigating
Node's `--experimental-modules` option it looks like it's suitable for our use
so this switches all tests to using JS files (moving away from TypeScript as
well) with `--experimental-modules` with Node.
Tests will be selectively re-enabled with webpack and node.js specific output
(that doesn't require `--experimental-modules`), coming in later commits.
* Restore the node test for node.js output
Ensures it's workable as-is
* Only generate typescript with webpack
* Only read wasm files for webpack
* Skip package.json/node_modules for now
* Only generate webpack config if needed
* Start a dedicated test module for typescript
Will hopefully verify the generated Typescript compiles OK.
* Remove unneeded `node` method
* Fixup some rebase conflicts
* Don't run asmjs example on travis
* Fixup generator tests
* Attempt to fix windows
* Comment windows fix
* More test fixes
* More exclusions
* More test fixes
* Relax eslint regex
Catch mjs modules as well
* Fix eslint
* Speed up travis on examples slightly
