* Compiler no longer has its own Tokio runtime. Compiler handles one
message and then exits.
* Uses the simpler ts.CompilerHost interface instead of
ts.LanguageServiceHost.
* avoids recompiling the same module by introducing a hacky but simple
`hashset<string>` that stores the module names that have been already
compiled.
* Removes the CompilerConfig op.
* Removes a lot of the mocking stuff in compiler.ts like `this._ts`. It
is not useful as we don't even have tests.
* Turns off checkJs because it causes fmt_test to die with OOM.
Fixes some sed errors introduced in c43cfe.
Unfortunately moving libdeno required splitting build.rs into two parts,
one for cli and one for core.
I've also removed the arm64 build - it's complicating things at this
re-org and we're not even testing it. I need to swing back to it and get
tools/test.py running for it.
* Native ES modules
This is a major refactor of internal compiler.
Before: JS and TS both were sent through the typescript compiler where
their imports were parsed and handled. Both compiled to AMD JS and
finally sent to V8
Now: JS is sent directly into V8. TS is sent through the typescript
compiler, but tsc generates ES modules now instead of AMD. This
generated JS is then dumped into V8.
This should much faster for pure JS code. It may improve TS compilation
speed.
In the future this allows us to separate TS out of the runtime heap and
into its own dedicated snapshot. This will result in a smaller runtime
heap, and thus should be faster.
Some tests were unfortunately disabled to ease landing this patch:
1. compiler_tests.ts which I intend to bring back in later commits.
2. Some text_encoding_test.ts tests which made the file invalid utf8.
See PR for a discussion.
Also worth noting that this is necessary to support WASM
This reverts commit e976b3e041.
There is nothing technically wrong with this commit, but it's adding
complexity to a big refactor (native ES modules #975). Since it's not
necessary and simply a philosophical preference, I will revert for now
and try to bring it back later.
- Improves speed and binary size significantly.
- Makes deno_last_exception() output a JSON structure.
- Isolate::execute and Isolate::event_loop now return
structured, mapped JSError objects on errors.
- Removes libdeno functions:
libdeno.setGlobalErrorHandler()
libdeno.setPromiseRejectHandler()
libdeno.setPromiseErrorExaminer()
In collaboration with Ryan Dahl.
