GLib / D-Bus plugin?
by Phil B 22 Aug '18

22 Aug '18

I was curious if anyone has done any work on plugin support for this? I saw a post from Mariano back in 2016 but no one replied. So just wondering (Mariano? Others?) has done anything on this front? Thanks, Phil

[OpenSmalltalk/opensmalltalk-vm] Provide control over VM messages (#275)
by Damien Pollet 20 Aug '18

20 Aug '18

Could the VM provide an option for separating its own output from the image's output? Concretely, the VM complains about pthread_setschedparam in my Travis builds, which prevents writing command-line scripts with clean output both on stdout and stderr. See https://github.com/hpi-swa/smalltalkCI/issues/388 Maybe it's possible to play with the file descriptors at image startup, but it would make sense if the VM itself had something like a `--silent` or a `--vm-stderr FILE` flag (the JVM has `-Xlog`) to redirect its diagnostic messages so that anything that goes to stdout or stderr exclusively comes from the image. -- You are receiving this because you are subscribed to this thread.

[OpenSmalltalk/opensmalltalk-vm] Suppress rtprio warning when ${CI} env var is set (#279)
by Fabio Niephaus 19 Aug '18

19 Aug '18

This makes the rtprio warning less verbose when the `${CI}` env var is set. `${CI}` is usually set by common CI providers, see: - https://docs.travis-ci.com/user/environment-variables/#default-environment-… - https://www.appveyor.com/docs/environment-variables/ - https://docs.gitlab.com/ee/ci/variables/#predefined-variables-environment-v… "pthread_setschedparam failed: Operation not permitted" is still printed to inform about the misconfiguration. If no one objects, I will merge this in the next couple of days...

[OpenSmalltalk/opensmalltalk-vm] primitiveFileStdioHandles() fails to return nil if stdio file is not available (#274)
by akgrant43 19 Aug '18

19 Aug '18

According to the comment for primitiveFileStdioHandles(): Answer an Array of file handles for standard in, standard out and standard error, with nil in entries that are unvailable, e.g. because the platform does not provide standard error, etc. However, on Windows in practice an array of sqFile entries with null handles is returned. The image is unable to distinguish between valid and invalid entries since sqFile is specific to the VM. Modify the Windows VM so that nil is returned if stdio is unavailable. Check linux behaviour. PR will be provided (eventually). Cheers, Alistair -- You are receiving this because you are subscribed to this thread.

[OpenSmalltalk/opensmalltalk-vm] Refactor cygwin installation for appveyor (#242)
by CyrilFerlicot 19 Aug '18

19 Aug '18

Now the installation is extracted to a reusable batch script and install all dependencies, including the ones installed by default on appveyor. This allows the users of the vm to use the script to build their own cygwin to compile the vm without having to look for all needed dependencies. I am not sure it will work at the first try. I do a PR to let appveyor test it for me.
