A major API change was that asserts are imported from testing/asserts.ts
now rather than testing/mod.ts and assertEqual as renamed to
assertEquals to conform to what is most common in JavaScript.
This patch contains a special hack that circumvents the current tokio
seek problem.
tokio `seek` is implemented to take ownership of the original File and
emit a new one in its future, which conflicts with the design of
ResourceTable.
To avoid the problem, the current hack makes the FsFile resource
an Option which we could `take` the value ownership out of it. We then
convert the tokio File into a Rust std File, perform the seek, and then
put it back into the resource.
This might be able to drop this hack after
https://github.com/tokio-rs/tokio/pull/785 lands.
Resolves #1705
This PR adds the Deno APIs as a global namespace named `Deno`. For backwards
compatibility, the ability to `import * from "deno"` is preserved. I have tried
to convert every test and internal code the references the module to use the
namespace instead, but because I didn't break compatibility I am not sure.
On the REPL, `deno` no longer exists, replaced only with `Deno` to align with
the regular runtime.
The runtime type library includes both the namespace and module. This means it
duplicates the whole type information. When we remove the functionality from the
runtime, it will be a one line change to the library generator to remove the
module definition from the type library.
I marked a `TODO` in a couple places where to remove the `"deno"` module, but
there are additional places I know I didn't mark.
