Fix bug in regular expression and make the regular expression more
strict.
In a string passed to new RegExp(), '[\t\s]' is identical to '[ts]' and
not `/[\t\s]/`. For that, the backslash needs to be escaped in the
string. Futhermore, `\t` is the tab character and is included in the
special regexp value `\s` so is unnecessary.
That would reduce the RegExp to new RegExp(`^${value}\\s*;?`) but
there's no point in matching 0 or more space characters followed by 0 or
one semi-colons as that will match no matter what follows `value`.
To make it more strict, require one of space, semicolon, or
end-of-string after value.
Allowlist checking already uses hosts but for some reason
requests, revokes and the runtime permissions API use URLs.
- BREAKING(lib.deno.unstable.d.ts): Change
NetPermissionDescriptor::url to NetPermissionDescriptor::host
- fix(runtime/permissions): Don't add whole URLs to the
allowlist on request
- fix(runtime/permissions): Harden strength semantics:
({ name: "net", host: "127.0.0.1" } is stronger than
{ name: "net", host: "127.0.0.1:8000" }) for blocklisting
- refactor(runtime/permissions): Use tuples for hosts, make
the host optional in Permissions::{query_net, request_net, revoke_net}()
This PR refactors "cli/flags.rs" and "runtime/permissions.rs" so
that "allow_read", "allow_write" and "allow_net" themselves
have allowlists, instead of storing them in additional fields.
This commit rewrites "chown_test.ts" to use the GNU "id" command
instead of python. This won't work on Windows, but these tests aren't
currently run on Windows anyway.
Implementors of `deno_core::JsRuntime` might want to do additional actions
during each turn of event loop, eg. `deno_runtime::Worker` polls inspector,
`deno_runtime::WebWorker` receives/dispatches messages from/to worker host.
Previously `JsRuntime::mod_evaluate` was implemented in such fashion that it
only polled `JsRuntime`'s event loop. This behavior turned out to be wrong
in the example of `WebWorker` which couldn't receive/dispatch messages because
its implementation of event loop was never called.
This commit rewrites "mod_evaluate" to return a handle to receiver that resolves
when module's promise resolves. It is now implementors responsibility to poll
event loop after calling `mod_evaluate`.
This commit migrates all ops to use new resource table
and "AsyncRefCell".
Old implementation of resource table was completely
removed and all code referencing it was updated to use
new system.
