[squeak-dev] Metacello bootstrap fails due to download timeouts

Hi all,

My Travis CI builds for Squeak-Trunk 32 bits (and only these) started to
fail due to timeouts. When I looked at it in a Linux VM and it fails
to download Metacello-Base-dkh.109.mcz from SmalltalkHub. When I try
to access this version with a web browser, I get an error HTTP 500

A fresh 64 bit Trunk image from squeak.org when run on Windows instead
hangs when
downloading Metacello-Core-dkh.494.mcz when I do `Metacello new`.
Eventually it erred with "Error: retry with alternate repository
failed: 'ConnectionTimedOut: Data receive timed out.'" ...after about
half an hour or so. The error comes from
ConfigurationOfMetacello>>ensureMetacello:. Though it does look as if
it first tried with a repository at
http://seaside.gemtalksystems.com/ss/metacello and not SmalltalkHub. I
can download the version in a web browser without a problem:

Yet a local 64 bit trunk smalltalkCI build succeeded and I don't know
why yet. It also needs to go through the MetacelloStub, doesn't it?

For a start, does anyone experience the same problem or is it my bad
luck with the connections? To test, print `Metacello new` in a fresh image
which does not have the Metacello class yet.

Now SmalltalkHub is deprecated as you can read on its
front page. http://smalltalkhub.com/

Tom, Tobias, Dale, you already started to discuss changing the
bootstrap of current Metacello in Squeak when the Tonel changes were
integrated, didn't you? Is there a path where we can live without any
unmaintained repositories like the ones on SmalltalkHub?

On a different level: shouldn't the bootstrapping of the
MetacelloStub, or rather the downloading of version signal an error
with a timeout sooner when it cannot retrieve a
version, instead of waiting or retrying for a long time?

Kind regards,
