process priority
by t olschewski Nov. 22, 2011

Nov. 22, 2011

I've some more questions: 1. is there a way to run "do-it"s and other user activity at a priority of 40, say, by default ? I know I can say "p := [ ... lenghty ...] forkAt: 40" and "p terminate" anytime in order to prevent user interface from freezing. 2. are my "forkAt:" processes supposed to appear in the Process Browser and if yes: where do I find them ? 3. If I open a workspace and a Transcript in a new (1.3-13315) image and run: p := [ 1 to: 10 do: [ :n | Transcript show: n; cr; cr; show: n factorial; cr; cr ]] forkAt: 40. then everything works fine. If I replace 10 by 1000 (don't do this yourself) then sometimes after a while the Transcript window turns red with two yellow lines and a debug window pops up with varying errors (mostly "subscript out of bounds"). Then again, in some cases it runs with no error. I have seen this in squeak 4.2, too. -- View this message in context: http://forum.world.st/process-priority-tp4092574p4092574.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

GlorpDBX
by Jonathan Kelly Nov. 22, 2011

Nov. 22, 2011

Hi, feeling particularly stupid right now. Been trying to get Glorp DBX working with Postgresql for the last 2 hours and I'm busted. It took me about an out just to find out how to load and configure things. ugh. It took me a while to work out I had to actually install OpenDBX (doh). So I have downloaded that and added the directory to my PATH. So I'm trying to run the tests and I get DBXFatalError: FATAL OpenDBX: Loading backend library failed. I know it's finding OpenDBX, because when I move the OpenDBX folder, I get a different error - "Error: External Module Not Found" from apiInitialize (and I can see it's trying to load libopendbx-1.dll). Part of my problem is squeakdbx.org domain expired on 09/27/11 and is now a godaddy parking page. double ugh. Anyone got any ideas? I'm running a fresh 1.3 using CogVM-Win-13307 install on Windows XP. Jonathan.

OSProcess reading utf8 files
by Francois Stephany Nov. 20, 2011

Nov. 20, 2011

Hi, Reading an utf8 file with OSProcess results in some weird characters showing up. (PipeableOSProcess command: 'less /path/to/a/text/file') output. -> inspect the bytestring and get some non-ascii characters fucked up. Doing `less /path/to/a/text/file` in a terminal displays the file fine. That's probably something stupid on my side but I cannot get it working. Any idea ? Cheers, Francois

Something like XDV/Diazo/Deliverance in Smalltalk?
by Offray Vladimir Luna CÃ¡rdenas Nov. 18, 2011

Nov. 18, 2011

Hi, Me and a group of friends in a local hackerspace[1] want to intervene the interface of this Cynin site using the technologies of Diazo[2], Xdv[3] or Deliverance[4]. Seeing the way that views are wrote in Seaside I wondder if there is someway to make a similar intervention/integration of interface without touching directly the code a la Diazo/XDV/Deliverance but using Seaside/Zinc or some similar combination. [1] http://hackbo.co/ [2] http://diazo.org/index.html [3] http://www.enfoldsystems.com/software/proxy/docs/6.0/xdvtutorial.html [4] http://packages.python.org/Deliverance/ Any pointer will be appreciated. Cheers, Offray

Changing Cherokee for a Smalltalk based web server?
by Offray Vladimir Luna CÃ¡rdenas Nov. 18, 2011

Nov. 18, 2011

Hi all, I'm getting random "504 gateway error" answers from several sites (using Zope and Rails) that are served by Cherokee using a reverse proxy setup. This error is an open issue in Cherokee and has been reported and not properly patched since 2009: https://code.google.com/p/cherokee/issues/detail?id=504 I did choose Cherokee because of its easiness to setup and newbie friendly interface and character, but with this problem I'm thinking in testing another server, may be a Smalltalk based one that have similar characteristics and can serve sites in Zope or Rails also. I know about Comanche, Swazoo and Zinc, but I don't know which of them is better (making load balance and stuff like that) and have proper documentation about using it in combination with other software (Zope and Rails in my case). Any advice on this matter is greatly appreciated, Offray

VSE / VW migration to Pharo
by Chantal Thibodeau Nov. 17, 2011

Nov. 17, 2011

Hi We want to migrate code from VisualWorks 3.0 to something else. It is a batch search engine so the GUI is extremely simple and could be rewrite from scratch. I tried the VW 7.0 but it is too costly (but it works perfectly fine with small adjusments in less than one hour). I installed Pharo and I am unabled to even load some code. I read that everything should be in the repository. Fine for the new code but what do I do with the "old" one ? I don't see anywhere to load a source file or a parcel file. I need some help. I also download Squeak, that I will try in the next days. The speed of execution is the main issue. Thanks a lot

Pharse Node
by Pablo Herrero Nov. 17, 2011

Nov. 17, 2011

Hello everybody! I'm looking for documentation for the ParseNode class's hierarchy at the 'Compiler-ParseNodes' category. Does anyone know where I could find some? PS1: I'm working on a project where I need to do some runtime code manipulation, like creating AST Nodes on the fly and things like that. PS2: Is this the correct list to post this questing or pharo-project might be more apt? Cheers! Pablo

The Pharo curse
by Jeff Gray Nov. 17, 2011

Nov. 17, 2011

In my day job I write a lot of documents. I'm finding that the more I use Pharo, when typing in MS Word I select a piece of text and press ( and then wonder where all the text has gone :-) Maybe the answer is to use Pharo for word processing... -- View this message in context: http://forum.world.st/The-Pharo-curse-tp4078843p4078843.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

[ANN] SqueakSource 3 RC 1
by Tobias Pape Nov. 16, 2011

Nov. 16, 2011

Dear All, I hereby release SqueakSource 3 RC 1 to the public. I wasn't able to come up with a nice name this time, so it is just 'the Release Candidate' :) Thanks to Dale, Norbert, and Philippe for their support, to many I met at ESUG'11 who gave good inspiration and anybody who listened and helped. == Improvements since the Beta: - Backgrounding does not fork but use a separate process on Squeak; Service VM on GS. - New feature: "well known name" for a Repo, like Squeaksource or gemsource... (So, that Gofer new gemsource: â¦ can be used in the Repo strings on the project sites) - Improvements in Sitemap building, XML-parser not required, plain Seaside - Pick up newer versions of several, esp. gemstone projects. Email support should be back now. - Fix display of "news" section - Fix for #9: Sorting of Projects can be confusing. - Fix: by default, non-world-read projects are not visible, now. - Fix for #7: "Tags" link responds with MessageNotUnderstood page - Fix for #22: SSProject>>versionAdded: forks a process - Fix for #23: Sitemap generation fails - Fix for #24: SSVersionAlreadyExists thrown by SSVersionView>>move:to: but not handled... - Fix for #27: MNU #ifNotEmpty: in SSEmailSubscription >> versionAdded:to: nukes gem - Fix for #29: add "breathing space" in tables'. - HTTP DELETE for versions (e.g., for future Monticello tool usage) - more tests. == The (up to now) sole instance is the HPIâs Software Architecture Groupâs Squeaksource, wich is not open to registration at the moment. However, I hope the GemStone ss3 instance will be migrated soon (http://ss3.gemstone.com) Install it yourself! Pharo: == Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfSqueakSource'; load. ((Smalltalk at: #ConfigurationOfSqueakSource) project version: '3.0-rc.1') load: #('All') == Squeak: == Installer ss project: 'MetacelloRepository'; load: 'ConfigurationOfSqueakSource'. ((Smalltalk at: #ConfigurationOfSqueakSource) project version: '3.0-rc.1') load: #('All') == GemStone (with ProjectGofer, else like pharo): == Gofer project load: 'SqueakSource' version: '3.0-rc.1' group: #('All'). == To come: === â¢ more tests â¢ moving and copying via backend (i.e., HTTP request) â¢ inboxes â¢ branch projects â¢ (converting squeaksource.com to a SqueakSource3 ;) ) === I hope you like it. Best -Tobias PS: Did you know that â¢ you can get a personal rss stream of your âfavouriteâ projects? (like following on github) â¢ you can set up parent projects for your projects and automatically move all your packages there? â¢ you can extend SqueakSource quite easily? (Example: Issues) â¢ you can install a stripped down version on SqueakSource? (e.g., without Issue tracking, Statistics or filesystem support)
