Pharo Cog Spur Virtual Machine has stopped working, restore a broken image

When I try to launch a Pharo Image that I have been working on, Pharo opens, but then immediately crashes.

Can anyone help me figure out how to either:

  1. save my image?
  2. save the code in my image to copy to a new image?
  3. dig in and investigate this further?

When I open my image, it now crashes and shows the following crash message:

Pharo Cog Spur Virtual Machine has stopped working

In the details, I get the problem signature:

I am launching my Image from "Pharo Launcher version: 2.2".

My image was created from the template: Image template (Pharo 8.0 - 64bit (stable))

In my image I loaded Roassal3 from github://ObjectProfile/Roassal3:v0.9.5

I tried copying my image, and opening the copy, but same result (as expected I guess).

I had a look at PharDebug.log, but I'm not really sure what I'm looking for. This is a copy of by PhaorDebug.log.

Thanks

Solution

  • I started to answer in comment then it got too long for it.

    It is always best to save your work to CVS like merucrial or git. Pharo has a facility called iceberg for git. I would recommend pushing your changes instead of relying on the image. You have to then recover the file using the *.changes file.

    Also it would be helpful to see the PharoDebug.log. You can share it with us via pastebin.com or similar.

    If the Cogs VM crashes on you you have to go to a .changes file which should have the same name as your image file.

    For example:

    For image Pharo8.0-command_line.image, you will find your changes in Pharo8.0-command_line.changes file.

    To recover your code:

    1. Backup your changes file
    2. Download a fresh new image
    3. Run Pharo with new image
    4. Drag the .changes file into Pharo
    5. Use Change browser to pick up the code you want to recover.

    You should report the bug at Bug report for Pharo.
