Development for LHC@home

I set my job_2025_04_15.toml to Verbose = 2 and that I only run theroy tasks.

if you want to check the tasks here my host

I think the issue is that your task names are too long for the code in 18/22, I made my own patched version of 18 as a workaround. the PR #7113 was the fix from David, so if you want a new wrapper then you would need one build from source after this PR, 22 does not contain this as it was made before the PR.

I don't know about 22c where this was in the PR list.

I built a patched 22 with the code cherry picked from PR #7113 and dropped it in to see if it fixes it.

The Verbose = 2 does not work as they have in the wrapper code that the verbose flag is alway set to VERBOSE_STD, so it would need a tweek of the 22 code to restore the verbosity functionality.

It seems like this chery picked patch fixed it I got 2 sucessful WUs. I leave it running.

Is this anything to do with the Windows version?

its only in the Linux and macOS code so no effect for windows as windows uses a different code path to get the name of the container.

In reply to Toby Broom's message of 9 Oct 2026:

Very well investigated, Toby.
What I don't understand is that this too long name convention was already discovered over half a year ago and was already patched.
So that patch was forgetten in newer builds somehow.

Luckily you build a workable version on time, cause your daily quota for that host was fast shrinking to zero after all those errors.

they crashed after 60 s for almost every WU so it was not so hard to re-create the issue so it was quick and easy to replicate.

Claude did most of the work to sugest commands to see what was happening, you could see the name of the WU/container name getting truncated at 256 characters.

Did you open an issue upstream?

Yes, the issue was reported here:

https://github.com/BOINC/boinc/issues/7111

and fixed here:

https://github.com/BOINC/boinc/pull/7113

Version 22 was relased before this PR was merged so it does not contain this fix, the 32 bit version of 22 that you deployed I'm not sure how it was made but it seems like it was after this PR so it was working on Linux. if you built the wrapper from the 8.2.15 pre-release then it would also be OK from the release notes as this contains the PR.

I have deployed a version from today.

1st one was good

I think this is good to deploy, I got 3 in a row good.

Returned plenty of good results.
