Unfortunately V8 has a debug-only assert that checks
that a SnapshotCreator actually created a snapshot:
7d8c9aa769/v8/src/api.cc (L571)
This was not being triggered in Linux & Mac debug builds
because we were using the prebuilt release V8 build.
It was being triggered in Windows debug build because there is
a prebuilt v8_debug.lib. However the Windows error went unnoticed
because we only run release builds in CI.
- 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.
Ensure that at most one mutable Isolate reference exists at a time.
`deno_execute()` and `deno_respond()` now borrow a reference to the rust-side
isolate from the caller. When we need a reference to the isolate while one of
these functions is on the stack, `deno_get_data()` can be used to borrow back
that reference.
This is a large API refactor of deno.h which replaces
deno_send() and deno_set_response() with deno_respond().
It also adds a req_id parameter to the deno_recv_cb.
Make writeFile/writeFileSync use it.
