Here is a quick riddle for you:

The Context:

• os: debian
• vm: cog
• image: the image from the pier site, in which I updated to the

latest version of the pier packages. Pier runs on port 8087.

If I run the following line:

~/coglinux/bin/squeak x.image

the image starts with no error and port 8087 is open.

If I run the following line:

~/coglinux/bin/squeak -nodisplay -nosound x.image

the image just blocks and the port 8087 is not open.

do you have any idea what could be the reason? I tried with all the possible parameter combinations: (-headless, -vm-display-none)

If pier image is pharo based, which starting from version 1.3 introducing a logic around headless mode. It could be that something wrong there. But actually, it was introduced to prevent the situations as you describing (just hanging and doing nothing), so i cannot tell, what exactly may be wrong there. But most probably it is something wrong with startup code, which might rely on having UI, which is not there in headless mode.

It's pretty likely that the issue is with Pharo's non-interactive mode vs Pier. Since you're using Cog, you can easily find out where the problem is, by using kill -USR1 <pid> which prints the content of all stacks to stdout.

Hi Levente!

Thanks! I couldn't see anything wrong with the attached log though :( Is there any hint that you can recognize?

Thanks, M.
