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

Hi Paul, thanks for remark my post! :) The important here is that David Lewis has confirmed it fix the problem, http://forum.world.st/OSProcess-error-in-1-3-tp4602389p4607494.html But I don't know if you guys have here the same problem I had, because the issue was in Windows (). Just test change

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

and it seems that on windows the problem does not exist. So I could use OSSubprocess on unix and OSProcess on windows. 2016-06-10 9:25 GMT+02:00 Sabine Manaa : > Hi Nicolai, > > Thanks! I stopped all ZnServers with > WAServerManager default stopAll. > > Then I can do > Delay delaySchedulerClass:

Hi Nicolai, Thanks! I stopped all ZnServers with WAServerManager default stopAll. Then I can do Delay delaySchedulerClass: DelayMillisecondScheduler. without problems. 20 timesRepeat: [OSProcess command: ('echo "Hi there"').] . here, the problem persists -> locking image your code with OSSubpro

Hi @mariano: "Did you test if the one-liner (Delay delaySchedulerClass: DelayMillisecondScheduler.) fixes these lookups? " -> my config loads materialDesignLite (which loads seaside and magritte). after loading this and trying the one liner, my image does not respond anymore. you can reproduce i

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

Hi Sabine, I had a Pharo 5 image where running OSProcess waitForCommand:'ls' twice would lock everything up. Following Gaston's suggestion here: http://forum.world.st/Problem-with-delay-waiting-OSSubprocess-code-on-Pharo-5-0-td4895780.html#a4898158 Fixed it for me. Maybe we hit the same issu

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

Sabine, I did not yet tested OSProcess but with OSSubprocess (in 5.0) I cannot reproduce the issue: *Polling strategy works:* Delay delaySchedulerClass: DelayMillisecondScheduler. 20 timesRepeat: [OSSUnixSubprocess new command: 'echo'; arguments: { ' }; redirectStdout; *runAndWaitPollingEvery: (

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

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

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

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. Sabine

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

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

Sabine, Did you test if the one-liner (Delay delaySchedulerClass: DelayMillisecondScheduler.) fixes these lookups? Thanks On Wed, Jun 8, 2016 at 5:31 AM, Sabine Manaa wrote: > Hi Thierry, all, > > you were right, it was not so complicated to write my own version for > calling an external prog

Hi Thierry, all, you were right, it was not so complicated to write my own version for calling an external program based on your Github code. It worked fine on Pharo3+4 but on Pharo5 there are the locking problems described, also in your code. Until there is a decision if supporting windows in OS

Hi guys, I will try to answer many things at once: 1) Sabine, OSSubprocess works for Unix derived, not only Linux, that includes OSX as well. 2) Tierry,Sabine for the case of loosing signals, the most trustful solution (in OSSubprocess) is to rely on a delay pooling instead of on the child reape

Hi Sabine, which version of Pharo are you using? I had similar issues, and I managed to reduce those occurrences to a reasonable level by changing the way I called OSProcess (and a lot of help from Dave). I do have sometime lockups with OSSubprocess as well, but those are also rare. (I do think t

Hi, sorry but I have another issue with OSProcess. For my app, I want to show small .png previews from my .pdfs. For this reason, I use an external software, currently pdfbox. It works fine, but regularly, I get a hanging image. I tried to reproduce it and found out, that it is not a problem with
