Upgrade deno_std

[ry]

In particular to have this improvement to http_bench.ts

depends on #2065

[ry]

This is failing because the unit test summary is printed twice for some reason.

> ./target/debug/deno --no-prompt js/unit_tests.ts permR0W0N0E0U0
[...]
test createSyscallCountColumnsIrregularData_permR0W0N0E0U0 ... ok
test createSha1ListRegularData_permR0W0N0E0U0 ... ok

running 0 tests

test result: ok. 0 passed; 0 failed; 181 ignored; 0 measured; 112 filtered out

I assume this has something to do with the flag changes... Any idea @kt3k @bartlomieju ?

@ry
If I replaced the following line of unit_tests.ts:

import "deps/https/deno.land/std/testing/main.ts";

to the following:

import { runTests } from "deps/https/deno.land/std/testing/mod.ts";
runTests();

Then tests seem working normally (but I found another failure with deno fmt)

(Is std/testing/main.ts intended as the general entrypoint of testing?)

[bartlomieju]

In testing/main.ts:

// Copyright 2018-2019 the Deno authors. All rights reserved. MIT license.
import { runTests } from "./mod.ts";

async function main() {
  // Testing entire test suite serially
  await runTests();
  // Testing parallel execution on a subset that does not depend on exec order
  await runTests({ parallel: true, only: /^testing/ });
}

main();

There shouldn't be two calls to runTests. This was changed in denoland/std#309

It was to test if parallel and serial test running were working properly. We encountered a non tested case when changing the exitonfail property.

(but I found another failure with deno fmt)

@kt3k what's the problem?

EDIT: I can see the problem in current Travis build. Unfortunately I can get to debug it in the evening

[ry]

@bartlomieju @zekth I think the future we should fail noisily if runIfMain() is called more than once.

[bartlomieju]

@ry agreed, however that wouldn't prevent this error. It was runTests that was called multiple times, and I think that might be desired actually.
