[Vm-dev] [squeak-dev] Looking for a new VM release candidate (was: Broken 5.3 downloads need fixing)

Well, there are no builds for that version. Are you referring to the build 202004210425?
https://bintray.com/opensmalltalk/vm/cog/202004210425#files [https://bintray.com/opensmalltalk/vm/cog/202004210425#files]

So, that would be like bleeding edge, right? Are there any experiments going in these days? Could someone sum up what happened since mid March there?

Hi Tim!

Yes, let's make a new VM release to be used in Squeak 5.3 and 6.0alpha. I think we should start this dicussion on vm-dev, so I cross-post this.

Once we find a new candidate that was build after March 24 to fix the ARM bug you mentioned, we can update the CI and the bundles. (https://github.com/OpenSmalltalk/opensmalltalk-vm/releases [https://github.com/OpenSmalltalk/opensmalltalk-vm/releases])

That new release will then be copied over to the CI's base files:
http://files.squeak.org/base/ [http://files.squeak.org/base/]

Once the new bundles are produced...
http://files.squeak.org/5.3/ [http://files.squeak.org/5.3/]

http://files.squeak.org/6.0alpha/ [http://files.squeak.org/6.0alpha/]
...we can update squeak.org [http://squeak.org].

But first things first: We need to find a new release candidate for the VM to be tested at least a week. Tim proposed the following version:


Eliot? Nicolas? Any thoughts on this?

Can we please use 

CoInterpreter VMMaker.oscog-eem.2741 uuid: 809e8b1f-fe07-4d33-bfc1-db9e5ab13a99 Apr 15 2020

VM: 202004192151 CommitHash: 6e5241e

This has this one change that I'd like to be in the VM:

    Spur: Make sure that becomeForward: answers a useful error code for read-only targets (when copyHash is true).

The VM included in the 5.3 package for the ARM linux systems is fatally broken due to a code generator bug; we had various discussions about the issue in mid-March. We also noticed a problem with the bitBLT code for all platforms that was fixed by VMMaker.oscog-nice.2732

We really need to push the magic buttons to replace the ARM package in order for it to run at all; updating the other platforms to fix bitBLT would be nice. A quick test of the next available VM on bintray suggests that the https://bintray.com/opensmalltalk/vm/download_file?file_path=squeak.cog.spur_linux32ARMv6_202003291024.tar.gz [https://bintray.com/opensmalltalk/vm/download_file?file_path=squeak.cog.spur_linux32ARMv6_202003291024.tar.gz] version is functional - but maybe we want to use the latest?

What needs doing to solve this for the download page?
