Troubles using Pharo 2.0 one-click package on a secured WinXP
by Mun Mun Aug. 7, 2013

Aug. 7, 2013

Hi ! I'm quite new to Smalltalk and and so far, I've used Pharo on a regular XP system and everything went well. I'll add that my image occupy ~40 Mo in memory. I've recently tried to deploy my small app on the target system which is a very seccured package of WinXP. I can't help much on describing the specificities of the system as I'm just the user. But the system is cleared of unused services, there is a lot of account auditing, temporary files are explicitly written off the disk at logoff and so on. When launching the VM, I'm offered to choose an image to open and the following happen (I monitor the launching using the task manager) : Â¤ The first ~40 Mo are quickly allocated in memory Â¤ More memory is slowly allocated to the Pharo.exe process Â¤ After ~5 min, 100Mo allocated and counting, I stop the process and never get to see the Pharo GUI Is there a way for me to trace/dump what the VM is doing and maybe get help here to make my app work ? Complementary information : Â¤ I made a very crappy deployement: due to recent restrictions, I could not download a fresh and clean Pharo image. I picked the cleanest I had used, removed the various tutorial packages I had made (LOCell and stuff ;) and loaded the Monticello package of my little app. Â¤ The target system run on a VM (with something like VSphere). My understanding is that we have a cheap virtualization setup which is not adapted at all for XP.

Pharo 2.0 on Fedora 18
by edwin ancaer Aug. 5, 2013

Aug. 5, 2013

Hello, I'm running Pharo 2.0 on Fedora 18. I seem to have an issue with libssl.so which on my system is 1.0.1e, while libSquekSSL.so looks for version 0.9.8, as described here:Zodiac mail sending in Pharo smalltalk<http://stackoverflow.com/questions/12293670/zodiac-mail-sending-in-pharo-sm…>. Does anyone know how to solve this? Creating a symbolic link from 0.9.8 to 1.0.1e does not solve the problem [edwin@ottopedi bin]# ldd libSqueakSSL.so *./libSqueakSSL.so: /lib/libssl.so.0.9.8: version `OPENSSL_0.9.8' not found (required by ./libSqueakSSL.so)* linux-gate.so.1 => (0x001d2000) libssl.so.0.9.8 => /lib/libssl.so.0.9.8 (0x00161000) libc.so.6 => /lib/libc.so.6 (0x003a5000) libgssapi_krb5.so.2 => /lib/libgssapi_krb5.so.2 (0x00342000) libkrb5.so.3 => /lib/libkrb5.so.3 (0x001d3000) libcom_err.so.2 => /lib/libcom_err.so.2 (0x009ec000) libk5crypto.so.3 => /lib/libk5crypto.so.3 (0x00b76000) libresolv.so.2 => /lib/libresolv.so.2 (0x002b3000) libcrypto.so.10 => /lib/libcrypto.so.10 (0x0068a000) libdl.so.2 => /lib/libdl.so.2 (0x0087a000) libz.so.1 => /lib/libz.so.1 (0x00300000) /lib/ld-linux.so.2 (0x4ed07000) libkrb5support.so.0 => /lib/libkrb5support.so.0 (0x00bcd000) libkeyutils.so.1 => /lib/libkeyutils.so.1 (0x00c36000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x0091d000) libpthread.so.0 => /lib/libpthread.so.0 (0x002cc000) libselinux.so.1 => /lib/libselinux.so.1 (0x0097f000) libpcre.so.1 => /lib/libpcre.so.1 (0x0055b000) : Is there anyone who managed to install the version 0.9.8 and 1.0.1e of the openssl rpm on the same machine? Or is nobidy on Fedora 18 using Pharo? Thanks in advance, Edwin Ancaer

OSProcess execution from specific directory
by Juraj Kubelka Aug. 5, 2013

Aug. 5, 2013

Hi! On execution of (PipeableOSProcess command: 'pwd') output , it always says root directory ("/"). Is it possible to execute command from specific directory? Or the only correct solution is like this?: (PipeableOSProcess command: 'cd /Users/jura/ ; pwd') output Thanks a lot. Cheers, Jura

XMLWriter Class
by Mohammad Al Houssami (Alumni) Aug. 5, 2013

Aug. 5, 2013

I have asked about this earlier. I am using the XML library and in XML-Parser-Nodes there is a method printOn printOn: aStream (XMLWriter on: aStream) writeWith: [:writer | self writeXMLOn: writer]. Since I didn't have XMLWriter I thought it would be inside the XML-Writer package but apparently it is not. Can I know what package has this class? Or if there is anyway to solve this problem? Thanks again :)

Re: [Pharo-users] Does zinc support server sent events?
by Andy Burnett Aug. 5, 2013

Aug. 5, 2013

Sven said >>> Assuming you mean http://en.wikipedia.org/wiki/Server-sent_events the answer is no or not yet. It doesn't look very complicated though, given the fact that Zinc WebSockets do already work. I will start by reading the specs. <<< Sounds great! Please let me know if I can help in any way.

Pharo 2.0 with Seaside + DBXTalk + GlorpDBX + Magritte 3 + TWBS is getting slower and slower
by phil＠highoctane.be Aug. 4, 2013

Aug. 4, 2013

Hello, I've been loading all of those packages in order to build a full web stack development image. Everything now loads fine and kind of works but... The image is really slowing down and the size is getting very large. Here is the current one: 332580684 29 jul 10:50 Pharo-DripfeedIt-Magritte3-OpenDBX_20130729_1050.image 300+ megs... I've been doing some development in there and started looking for why this was getting so large and slow. I did a SpaceTally print analysis and imported the results in a spreadsheet. Look at the top consumers, especially the Semaphore thing. It is way beyond whatever was expected. There is something wrong there. There must be a leak of Points, MorphExtensions and I can't just figure out why there are so many Floats. I've been running test suites for some of the packages (e.g. OpenDBX and Glorp) and this may be the result. This image is kind of what one doing web dev would end up with. But then, it is very hard to get rid of that unwanted space. I am trying to build a system I can start using for business projects and feel concerned about that memory growth very seriously. Any pointers (I chased some already but here, there are way too many entries); Thx Phil

I was wondering about using them instead of Websockets. Cheers Andy

Storing test data in methods
by Norbert Hartl Aug. 2, 2013

Aug. 2, 2013

I try to untangle my modules. I have a parser that creates a model and a tool that uses that model. For testing it is convenient to just generate the model and work with it. But this way I introduce dependencies which always pulls everything in. In order to untangle I would need a way to easily serialize the runtime model into methods or something similar. Anything that can be transported via monticello is ok. I just don't want to have dependencies to present of external files. That would just change the problem but not solving it. Any ideas? Norbert

[DOC] Building and deploying your first web app with Pharo
by Sven Van Caekenberghe Aug. 1, 2013

Aug. 1, 2013

Hi, I wrote a new tutorial, "Building and deploying your first web app with Pharo - Understanding HTTP fundamentals through Zinc HTTP Components". By chronologically following the development process, you will see a small web app growing from something trivial to the final result. Finally, we will save our source code in a repository and deploy for real in the cloud. http://zn.stfx.eu/zn/build-and-deploy-1st-webapp Pharo 2.0/3.0 features such as Nautilus, SmalltalkHub, Metacello Configurations, Zeroconf Scripts and of course Zinc HTTP Components are used while highlighting traditional strengths such as incremental, live & interactive development in a rich environment. Enjoy, Sven PS: Feedback is welcome, the source document lives here https://github.com/svenvc/zinc/blob/master/build-and-deploy-1st-webapp/buil… - pull requests appreciated. -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org

Packages ... group view example
by Geert Claes Aug. 1, 2013

Aug. 1, 2013

I know I have seen it somewhere but I can't seem to find it. Can someone point me to an example where the packages are parsed by the "-"? e.g. Dsplayed as: v AST v Core > Matching > Nodes > Parser > Pattern > Tokens > Visitors > Interpreter > Tests Instead of: AST-Core AST-Core-Matching AST-Core-Nodes AST-Core-Parser AST-Core-Pattern AST-Core-Tokens AST-Core-Visitors AST-Interpreter-Core AST-Interpreter-Extension AST-Interpreter-Test AST-Tests-Core Thanks! -- View this message in context: http://forum.world.st/Packages-group-view-example-tp4701657.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
