Error: "upstream request timeout" occurring on playground after clicking "Flash" #7

Closed deadprogram closed 4 years ago

deadprogram commented 4 years ago

The error "upstream request timeout" is occurring frequently on the Playground website when trying to download code using the "Flash" button.

I do not have the same issue/slowness when compiling inside the web interface for the simulator.

It seems to work for me, although it is also rather slow at the moment.

Might just be performance is too slow under current load? It used to be a lot faster...

For which target was this the case?

Might just be performance is too slow under current load?

Unlikely, it is little used. And even if there was a high load, GCP should just add more instances automatically.

There is a timeout of 20 seconds. I thought this was a reasonable upper limit, not expecting timeouts to happen. However, the samd-based boards are much slower to compile so probably are the reason why you're hitting a timeout.

OK that makes sense, as those were the only boards I actually tried, it seemed like a general slowdown vs. the performance of a new feature.

So you will up the timeout?

aykevl commented 4 years ago

Ok, updated to 30s. Hopefully that fixes it for now.

For the long term, the compiler should really be sped up (something I've been working on already for a looong time, https://github.com/tinygo-org/tinygo/issues/285).

OK closing for now. Will reopen if needed.
