Ceedling Freezes on first runner

[Stephen Osborn]

Trying to get ceedling to work but it hangs up when it gets to the first runner file. I am running in a msys64/mingw64 environment. Ruby 3.3.5 is install under MSYS2 and Ceedling 1.0.0-e06f844. Operating in a Windows Terminal running MSYS2, I get this result:

LI-FLP5DK3 ~/ceedling $ ceedling new fred
      create  fred
      create  fred/src
      create  fred/test
      create  fred/test/support
      create  fred/project.yml

🌱 New project 'fred' created at ./fred/

At this point it freezes. Pressing Ctrl+C, I get

🌱 Ceedling could not complete operations because of errors

Now the Windows Terminal is frozen, no cursor. I have to kill it.

What am I doing wrong?

Thanks for your help.

Hi, Stephen.

Could you kindly run this again with --verbosity=debug and provide the log?

And, are you able to provide your project configuration?

(Please try attaching both rather than pasting in the email thread.)

Run with --verbosity=debug. The entire project is in the attached zip file. The output is in the file debug.txt

Thanks

Stephen,

There's nothing wrong with your set up or commands. Ceedling 1.0.0 is effectively complete but pre-release. All that remains is some final issue resolution. There's a couple of issues specific to Windows we have not yet resolved. We think what you are experiencing is related to a possible Windows threading issue we have not yet found.

At the moment, I'm afraid I don't have a workaround or fix for you. We haven't yet been able to reproduce the problem so as to fix it.

p.s. Supporting Windows is consistently one of the most challenging aspects of the Ceedling project!

Mike, 

Thanks. That seems consistent with what I am seeing. It runs fine under WSL, so for now that is my workaround.

[Mike Karlesky]

Just to confirm — Is that WSL on the very same machine as the original problem in “pure” Windows?

[Stephen Osborn]

Correct. Same machine that Ceedling hangs when run under MSYS2.

[Mike Karlesky]

Stephen, which version of Ruby were your running on Windows when the original problem occurred?

[Stephen Osborn]

I think it was 3.3.1

[Mike Karlesky]

We found an issue with shell execution specific to Ruby 3.1 on Windows. Though one would expect it was fixed in 3.2 or 3.3 or, at minimum, documented somehow, we haven't found any clear indicators as to its status. We're implementing a fix as well as addressing what we believe are at least two more threading / shell problems that probably affect all users on all platforms but seem to show up most often in Windows.

Stephen,

After further investigation, we think we found the problem. There's been a handful of different reports on 1.0.0 prerelease that all sounded like some kind of threading edge case. For whatever reason it nearly always presents itself in Windows but quite infrequently and in nearly impossible to reproduce ways. Your report finally got us on the right path.

We can't declare the problem fixed quite yet. There's code clean up and lots more testing first. But, we are hopeful. When the fix is available in a new prerelease build, would you be so kind as to run it in your original setup? Our best opportunity to demonstrate that the problem is fixed is to ask those who reported issues to exercise their projects. We have not yet had much success in replicating the actual problems and have been implementing fixes against theories and technical knowledge of the mechanisms that we think are failing.

[Stephen Osborn]

Yes. Let me know when it is available.

[Mike Karlesky]

Hi, Stephen. Please give this Ceedling 1.0.0 prerelease a try and let us know what you find. Thank you!

Updated Ceedling. Ruby wanted an update, so did that. CDed into the fred directory and entered "ceedling" and it ran correctly. Yay!!!

Then in MSYS, I went into my project that I had been running tests from WSL, and it ran correctly. 

Thank you so much.
