[Vm-dev] How to make a "point" release with opensmalltalk-vm?

[Holger Freyther]

Hey,

I am looking into changing my deployment from pharo-vm.git to OpensmalltalkVM and as my CI is now crashing and has the notorious FreeType2 backtrace (seems the display is set to 0x0 and then ...) I might have a look but that brings me to the point of how can I take a VM, make a bugfix and ship it/use it.

With pharo-vm I was able to take the commit of the release, load the mc/ directory, make fixes, generate code[1], compile it and ship it but I struggle to do the same with Opensmalltalk VM.

Given a version statement like:

  Pharo VM version: 5.0-201803161038  Fri Mar 16 10:46:55 UTC 2018 gcc 4.8 [Production Spur VM]
  Built from: CoInterpreter VMMaker.oscog-eem.2359 uuid: b3273e3e-dd9d-4819-a928-7034e1cf412c Mar 16 2018

  Revision: VM: 201803161038 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $ Date: Fri Mar 16 11:38:09 2018 +0100 $
  Plugins: 201803161038 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $
  Build host: Linux travis-job-29216682-8f27-4f97-a3e7-e3bc246f0137 4.4.0-101-generic #124~14.04.1-Ubuntu SMP Fri Nov 10 19:05:36 UTC 2017 i686 i686 i686 GNU/Linux
  plugin path: /mnt/build/vm/lib/pharo/5.0-201803161038 [default: /mnt/build/vm/lib/pharo/5.0-201803161038/]


How do I find the git commit this was built from?

How do I load an image with the matching sources?


I am sorry if I missed this from the documentation.

[1] Yeah with Slang signed can go to unsigned or vice versa and funny things will happen
