Re: [Pharo-users] iCal Chronos for Pharo 5 => OSProcess

by Paul DeBruicker

Hi CÃ©drick, The iCal load fails or it puts up a warning that you must load some other classes (e.g. OSProcess) first before loading other definitions? The OSProcess use in the iCal package it pretty minimal and would be easy to split out into a separate package if you were motivated to port iCal to OSSubProcess. As for Chronos, I'm not positive but am pretty sure that OSProcess is only used for generating the Chronos time zone rules from the olson time zone db files. So I'd guess both iCal and Chronos will work fine for testing purposes without porting anything to OSSubProcess and just skipping the load of the OSProcess parts. Hope this helps Paul CÃ©drick BÃ©ler wrote > Hi all, > > Iâm trying to load the iCal package from the catalog.

Re: [Pharo-users] Pharo Launcher

by Tim Mackinnon

I also recall that on OSX (at least some later versions), Apple introduced a change whereby if you try and launch another vm from the same vm, it wouldnât open. You had to have a different vm on a different path for it to work correctly. I will try and resolve my original problem and see if this is still the case.

Re: [Pharo-users] Pharo Launcher

by Tim Mackinnon

Hi - thanks of the detailed answer, I had to take a break from my investigation but I am keen to get it working again. Its a shame I didnât spot the survey on the name nomenclature because I liked the old system as it makes it much more obvious from the name exactly what you are getting - e.g. a Moose Build XXXX, vs Pharo 4.0 - YYYY (I would say this, as I implemented it). Its a shame you didnât make it a feature switchable thing as I think youâve lost useful functionality. I will probably put it back and propose it as an option (if itâs vetoâd Iâll maintain my own version - but a switch should hopefully satisfy everyone). Iâll also see if we can make it look nice again - as Launcher used to be a good showcase of how to make a Pharo app look beautiful.

iCal Chronos for Pharo 5 => OSProcess

by CÃ©drick BÃ©ler

Hi all, Iâm trying to load the iCal package from the catalog. It is available on smalltalkhub. http://www.smalltalkhub.com/#!/~pdebruic/iCal It has some problem (installation fails) but the package is not tagged as Pharo5. Plus it seems to use OSProcess. Iâm trying to avoid to load OSProcess as I use OSSubprocess (probably for Chronos ?). Any idea on what I can do ? (Iâd like to install/evaluation iCal vCard and Chronos) Thanks for any help, Cheers, CÃ©drik

Re: [Pharo-users] Image not starting

by Mariano Martinez Peck

Hi Victor, In addition to what Christophe said, you can do the following: 0) Start the VM from command line as you already do: coral/pharo-vm/pharo coral/Pharo.image 1) get the pid of previous step 2) In the command line do: kill -SIGUSR1 XXX That should output the smalltalk stacktrace in the stdout. And that might give you an idea in which part it is hanging from the IMAGE side. Hope this helps.

Re: [Pharo-users] SQLite + Pharo

by Esteban A. Maringolo

I have no experience with SQLite other than for testing it on Glorp and using it in Android (that provides a locking mechanism to queue requests), but according to the documentation it depends on how the SQLite connection is opened, if it is opened in "Serialized" mode [1], then it is safe to have a multi threaded application operating on a single db file. Also, according to the docs the access is controlled by means of file locking [2], so if everything is finalized/closed properly you shouldn't have this issue. Regards!

I would try to run pharo through strace (http://linux.die.net/man/1/strace <http://linux.die.net/man/1/strace>). This way, you will probably see a system call trying to write to a file in read-only mode. Hope this helps.

Image not starting

Hello everyone, I'm currently working on the project file policy and I'm having a problem that I don't understand I import my code, configure my image as readOnly (Pharo won't try to write on changesFiles,source,image....), set the folder of the image in readonly and try to open the image again and it's not possible, I don't get any stacktrace so it's hard to understand the problem. PS : If we set back the folder in write mode, it's possible again to open the image again. Here is the code to reproduce the bug, could someone give me a clue please? sudo rm -r testPharo mkdir testPharo cd testPharo echo "Metacello new smalltalkhubUser: 'Uryon' project: 'Coral'; configuration: 'Coral'; version: #development; onConflictUseIncoming; load.
