UFFI and autoRelease
by Serge Stinckwich April 27, 2018

April 27, 2018

I'm using autoRelease on some FFIOpaqueObject instances. I need to test some behavior when I delete explicitly one of these objects. âHow to remove these objects from the finalization list, in order they are not freed two times. Something like ignoreFinalization ? -- Serge Stinckwich UMI UMMISCO 209 (SU/IRD/UY1) "Programs must be written for people to read, and only incidentally for machines to execute."http://www.doesnotunderstand.org/

TLS/SSL and SocketStreams
by Eric Gade April 25, 2018

April 25, 2018

Hello, In the process of maintaining a small IRC client I have written, I'm trying to add the option to connect over SSL. Of course ensuring valid certificates and the handshake et al is quite complicated. Instead I'm attempting to rely on Zodiac's `ZdcSecureSocketStream` instead of a regular `SocketStream` for the connection. Here is where I run into a snag: `ZdcSecureSocketStream` is it's own complete rewrite. And though there are attempts to keep many of the same messages as `SocketStream`, some of the key ones are missing. In particular, I would like to have `#upToAll:` and even `nextLine` if possible. Attempting to subclass and implement them myself has been a disaster, since `ZdcSecureSocketStream` is actually quite complex. Can anyone help me with the following: * Is there a better way to implement an SSL connection over a socket? * Who maintains Zodiac? How can I contact them? Thanks -- Eric

Launcher not launching
by Jan BlizniÄenko April 25, 2018

April 25, 2018

Hello On Windows 10, I updated launcher from the one on https://ci.inria.fr/pharo/view/Launcher/job/Package-and-Publish-Launcher-st… (1.0.1) to the one now on official website http://pharo.org/web/download (1.1), but the new launcher does not open any images. I can create, rename, remove images or do whatever with them, but they do no launch ... their VM gets downloaded, launcher closes (if it is set to close on launch - it does not close if not set so), then nothing - the image does not open, no new Pharo.exe process in list of processes in Windows. Tried disabling AV, (re)installing to different directory, selecting different directories for images and vms, trying various Pharo versions (from 3 to 7) of images, still nothing. It does not work with both old and new images (downloaded by old working launcher or by this new one). There are no exceptions, no crash dumps, nothing in stderr. Those images can be opened by double clicking on them or by dragging and dropping them on C:\Users\User\Documents\Pharo\vms\61-x86\Pharo.exe (or similar - the same executable as Launcher should use). Also if I install back the old launcher (1.0.1) again, it works. The new launcher does not work on both of my machines (both Windows 10 that are quite similar in config and installed applications). For now, I will stick with 1.0.1, but I would like to find a reason for this problem. Thank you Jan -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Right repo for TaskIt and features?
by Holger Freyther April 25, 2018

April 25, 2018

Hey! I look into using Taskit for a new development and wondered about some features. What is the right upstream repository? What are the goals to get builds greens? I wondered if somebody thought of remote task execution? What I am missing is handling for overload. E.g. before queuing too many tasks I would prefer an exception to be raised (or the task blocking/slowing down). Signalling an exception is probably more reasonable as one task could queue another task (while >>#value is being executed...). What are the plans here? I can mitigate by always using futures and using >>#waitForCompletion:.. Are there ideas how to add remote task scheduling? Maybe use Seamless for it? Have workers connect to the scheduler? Other ideas? Who would have time to review an approach and the code? cheers holger

Projects using Magritte meta models
by Rafael Luque April 25, 2018

April 25, 2018

Hi all, I'm studying Magritte reading the booklet, Seaside book chapter about it, and the source code in the image. Until now the examples I've found are related with Seaside. I wonder if there are other relevant projects I could study to discover other possible uses cases of Magritte. Thank you!

April 24, 2018

Hi, To use Smalltalk sketch scripts for additional unit tests, I need to file in these script files. I found FileStream>>fileIn: does the job. Is it the proper way to do it? Thanks Hilaire -- Dr. Geo http://drgeo.eu

April 23, 2018

Hi, With Roassal is it possible to make a treemap (https://en.wikipedia.org/wiki/Treemapping) of the memory use of an object and its instVars? I have a leak and am not sure where and its not one or two objects AFAIK.... Thanks Paul

I was thinking the vm is able to run more than one bytecode set. Why couldnât our vm support both Pharo and Java bytecodes? Sent from ProtonMail Mobile

Re: [Pharo-users] Where do we go now ?
by Joe Shirk April 23, 2018

April 23, 2018

I've been a lurk-fan for a long time but this brings up something that distressed me. Richard Eng, Smalltalk Renaissance hero loves to say Smalltalk's grammar/syntax fits on a postcard. But the vocabulary doesn't. There is nothing English-like about the always expanding bewildering library namespaces. GT what? Oh a newbie might eventually figure out it means Glamorous Toolkit. These are meaningless brands. In this drive to come up with creative names for "just objects" that explain nothing at all, Smalltalk is becoming like Java or PHP hell. Just look at those examples through the eyes of a novice. The purity is nowhere to be found. :( On Apr 13, 2018 1:56 AM, "Benoit St-Jean via Pharo-users" < pharo-users(a)lists.pharo.org> wrote: ---------- Forwarded message ---------- From: Benoit St-Jean <bstjean(a)yahoo.com> To: pharo-users(a)lists.pharo.org Cc: Bcc: Date: Fri, 13 Apr 2018 05:53:46 +0000 (UTC) Subject: Where do we go now ? Hello guys, Just a quick word to get some things straight because, quite frankly, I really don't know where we're heading. When Pharo started, the goal was to depart from Squeak and do a *major clean up* of all the code, especially Morphic. The promise of a new, clean & lean Smalltalk attracted a lot of people. And then... I'm looking at the Pharo 7.0 image right now and I just don't get where we're heading. Every Pharo release gets bigger, and bigger, and bigger. I don't mind the environment getting bigger if it adds functionalities or new tools but that's not quite the case here. LOTS of stuff is just duplicated. Do we really need 2 code completion classes (NECController, NOCController) ? Do we really need 2 system browsers (Nautilus, Calypso)? Do we really need 2 compilers (OpalCompiler, Compiler) ? Do we really need 8 delay schedulers (DelayMicrosecondScheduler, DelayMillisecondScheduler, DelayNullScheduler, DelayExperimentalSpinScheduler, DelaySpinScheduler, DelayTicklessScheduler, DelayExperimentalCourageousScheduler, DelayExperimentalSemaphoreScheduler) ? Do we really need 2 inspectors (GTInspector, EyeInspector) ? Do we really need 2 workspaces (GTPlayground, Workspace) ? Et cetera. Et cetera. Et cetera. I could go on, and on, and on... Pharo 5.1 had 5885 classes. Pharo 6.1 had 6481 classes. Pharo 7.0 alpha has 7612 classes. Can you see a trend? Pharo 5.1 had 416 preference settings. Pharo 6.1 had 494 preference settings. Pharo 7.0 alpha has 662 preference settings. Can you see a trend? Pharo 5.1 had a 27.44 MB image. Pharo 6.1 had a 35.18 MB image. Pharo 7.0 alpha has a 47.97 MB image. Can you see a trend? Add to that the fact that Pharo is a nightmare when you want to port code. Just with the 7.0 release, 61 classes will be deprecated (and lots more to come if you search for the string "deprecated" into the code, most of the time hidden in the comments of the soon-to-be-deprecated-in-Pharo-8-I-guess classes). You have code that deals with sockets, should you use the old Socket classes or convert everything to Zodiac? And why do we keep both "frameworks" in the image ? Pharo hasn't been backward compatible with "old socket classes" a looooooong time ago anyway! You have code that deals with dependencies, should you use the old dependents mechanism or convert everything to announcements? UI speaking, what framework should anyone use ? Athens? Something else? You have code that deals with streams, should you use the old stream classes or convert everything to Zinc ? And why do we keep both "frameworks" in the image ? Pharo hasn't been backward compatible with the old stream classes a looooooong time ago anyway! So what's the plan? For instance, should I keep using the Nautilus Browser or I should switch to the Calypso browser and get used to it because Nautilus will be deprecated? Or should I just don't care because a third system browser will be added in Pharo 8 just because "it's cool, let's add this one too!" ? Couldn't we just decide on what's "official" and what's a goodie or an external optional tool/package/framework the same way all other Smalltalks do? If you say Calypso is the official & supported browser, fine! Then just get Nautilus out of the image, create a nice loadable package for it and if someone prefers Nautilus, they'll just have to load it into the image, the same way VW has a gazillion optional tools/packages/frameworks you can load from a parcel! Whenever I get asked a simple question by a newbie like "Oh, which system browser should I use?", quite frankly, I don't know what to answer. Did we include Calypso to deprecate Nautilus later? Is Calypso just a proof of concept? Is it just an optional tool? What about all those delay schedulers? "I loaded this code from SqueakSource and it just doesn't work". Should I help the guy to fix it or just tell him to convert all the code to the corresponding framework in Pharo? Perhaps a little bit of clarity and details about what's coming and what's the plan would be beneficial to a lot of us. ----------------- BenoÃ®t St-Jean Yahoo!
