Re: [Pharo-users] OSProcess command - non responding image when calling often

by Sabine Manaa

Hi Mariano, if you take the download Image from the Pharo website, then load commandShell and then zinc from the catalog browser and then do Delay delaySchedulerClass: DelayMillisecondScheduler. and then 20 timesRepeat: [OSProcess command: ('echo "Hi there"').] Then you will get the lock. Does this help to find the reason for the problem? Regards Sabine

You're right, and I had tried this, however asking the session to login results in the following: UDBCSQLite3Connection(Object)>>doesNotUnderstand: #queryEncoding PharoDatabaseAccessor>>encoding GlorpSession>>loginIfError: GlorpSession>>login GlorpBookDescriptorSystem class>>getSession UndefinedObject>>DoIt In my image at least, there are no implementers of #queryEncoding.

Re: [Pharo-users] OSProcess command - non responding image when calling often

by Mariano Martinez Peck

As I said in a previous email I found out a bug in Pharo 5.0 related to delays. This affected OSSubprocess but could affect OSProcess as well. The workaround is setting ANOTHER kind of delay scheduler than the one that has the bug. I thought that the "locks" you were having could have been because of this issue. But if the workaround does not solve it, then the lockups you are having are because of another reason :( Cheers, On Wed, Jun 8, 2016 at 10:49 AM, Sabine Manaa <manaa.sabine(a)gmail.com> wrote: > I dont understand > > Am Mittwoch, 8.

Re: [Pharo-users] OSProcess command - non responding image when calling often

by Sabine Manaa

Hi Mariano, ok, now I understand. But it is not clear to me, why "Delay delaySchedulerClass: DelayMillisecondScheduler" creates the locked image in my case. With a new Pharo5 image, there is no lock. I have to find out, what is causing this locks and report this to you, I hope tomorrow.
