boincmgr unable to launch a second instance

[Ken Sharp]

Not sure if this is an upstream bug or not as I am unable to test on another Linux.

Open boincmgr, open Advanced menu and select "Launch another BOINC manager". Nothing happens.

This appears in the console:
execv: Permission denied

Cannot find anything in the syslog regarding permission conflicts.

Tried with upstream version 7.0.44 and the problem remains.

Could this be specific to Ubuntu?

Are you saying you have the problem with the official build too?

Could you please try boinc 7.0.47 from ppa:costamagnagianfranco/boinc ppa?

Thanks

[Ken Sharp (kennybobs)]

Yep, all versions I've tried from the official build up to 7.0.47 from the ppa have the same problem.

[Gianfranco Costamagna (costamagnagianfranco)]

Hi Ken, I see the same behaviour in my machines, definitively a bug, but I have this bug too with the official client build (from berkeley/dl website).

So I suggest you to report it directly upstream, otherwise I'll have a look at the source code, but this is an upstream bug, so is stupid to fix it on debian side.

I saw some your mail on boinc_alpha mailing list, so feel free to report this bug too :)

[Ken Sharp (kennybobs)]

Mail sent. Mailing list is private.

[Gianfranco Costamagna (costamagnagianfranco)]

No problem I read it :-)

Anyway the problem is how the exec calls boincmgr, I think I patched it yesterday night but only locally, before pushing anything to debian I just want to be sure the patch works in any case...

In the meanwhile you can run another boinc manager instance with
boincmgr --multiple
And maybe with --directory /etc/boinc-client as well

This still exists in saucy release 7.1.20+dfsg-1

[Ken Sharp (kennybobs)]

Was the patch accepted upstream?

[Gianfranco Costamagna (costamagnagianfranco)]

no way, the patch wasn't working for some reasons, I need to further investigate

[Ken Sharp (kennybobs)]

The process for reporting a bug upstream to BOINC seems to be to send an e-mail to a black hole, and then forget about it. The Trac system that they have installed is broken so there's no way at all to record a bug report!

[Gianfranco Costamagna (costamagnagianfranco)]

forwarded to boinc_alpha mail list

[Ken Sharp (kennybobs)]

I don't suppose there's been any kind of response?

[Gianfranco Costamagna (costamagnagianfranco)]

nope, I'll try to have a look soon (I hope)

[Ken Sharp (kennybobs)]

I'm guessing that nobody is interested in this.

[Gianfranco Costamagna (costamagnagianfranco)]

seems that nobody is interested in boinc anymore, and I don't have time to look at it :(

[ChristianB (djangofett)]

I could reproduce this with an upstream dev build. It seems something is going wrong when calling execv() which is not reported back internally, thus the lack of error messages. I'm filing an upstream bug report on github.

[ChristianB (djangofett)]

It turns out there was already a bug reported for that. I added the new info to https://github.com/BOINC/boinc/issues/1177

I don't know if I can spare the time to investigate but maybe someone on github picks up on this.

This bug was fixed in the package boinc - 7.6.33+dfsg-10

---------------
boinc (7.6.33+dfsg-10) unstable; urgency=medium
