Re: [Pharo-users] ApplicationSecurity Questions

Moved from Pharo-Devâ¦ > Please let me know how it is going Iâm at the point where I seem to have a basic understanding of the library and Iâm ready to integrate into an app Iâm writing. Here are a few questions, which I put into an issue [1] to fold back into the docs when the conversation is âcomplete" Repository Access The following code seems problematic: ASRepository class>>#repositoryNamed: aString â¦ ^ self allInstances detect: â¦ Isn't it possible that a rogue instance could be returned instead of the one that's part of the model? For example, some persistence libraries like SimpleImagePersistence replace segments of the object graph and might have the old and new copy present during a load. Where do Check Points Live? In the IGEVET app, it seems that each session hasA checkPoint which hasA repository. Is this the way youâd recommend using AS in a real app? It seems that the default repository implementation loads the whole user DB from disk via Fuel, so wouldnât that happen for each session?! 1. https://github.com/hernanmd/ApplicationSecurity/issues/3 <https://github.com/hernanmd/ApplicationSecurity/issues/3>

Pharo Launcher multiplicated PhLDeploymentScript
by Peter UhnÃ¡k June 29, 2018

June 29, 2018

Hi, I've noticed that when I save Pharo Launcher image (ctrl+shift+s), because I was changing something, then PhLDeploymentScript is added to the the startup classes list. PhLStartupManager startUpClasses "a SortedCollection(PhLDirectoryBasedImageRepository PhLSettingBrowser PhLDeploymentScript PhLDeploymentScript ...(atm 34x)... PhLDeploymentScript)" PhLStartupManager startUpClasses asSet "a Set(PhLDirectoryBasedImageRepository PhLDeploymentScript PhLSettingBrowser)" I didn't notice any impact on functionality or speed (although for some reason there is a significant delay between clicking on the PhL icon and the image opening), but nevertheless it probably should be deduplicated. Thanks. Peter

Iceberg - finding deleted classes, reverting versions?
by Tim Mackinnon June 28, 2018

June 28, 2018

Hi - I am interested in what the future holds with Iceberg for things like finding deleted classes or reverting to older versions of things. As we tend to use lots of classes in Smalltalk (and view them as cheap) - I often create them, then move behaviour around and delete things I donât need anymore. However, if you want to recover one of those classes - with Envy there was a useful concept of âshow me deleted classes in a packageâ and you would get a list that you could then browse and recover from. Even older squeaks had some nice tools to pull this information from the .changes file (and while not quite the same as envy, it did let a solo developer work efficiently). So I was a bit surprised yesterday in Pharo 6.1 - to struggle to find a class I knew that I had deleted. There seemed to be no easy way to do this - and I thought there was somewhere that had that âAvailable/Deleted classesâ menu. Eventually I went to iceberg and browsed older versions of my package and with some riffing - managed to find what a I wanted - but it definitely seemed harder than it should be - for a concept that feels natural to us. Iâve heard it mentioned that we might get âversionsâ behaviour back via git on a method or existing class - but what about Deleted classes - is this something we will be able to do more easily? Tim

Microservices using Pharo
by Andrei Stebakov June 27, 2018

June 27, 2018

Does anyone use Pharo for Miro services? I heard about Seaside and Teapot, just was wondering if Pharo can handle multiple simultaneous requests and if it can, where it reaches the limit.

copy & paste
by Otto Behrens June 27, 2018

June 27, 2018

Hi, A very annoying issue I'm having with Pharo 6.0 (running on Ubuntu 16.04) is that if I copy text from other applications (eg. chromium browser), I cannot paste it into Pharo. I get text copied in Pharo from a previous copy. To work around this, I have a "gedit" text editor open and I paste the text in there. After that, I cut it from the text editor and paste it into pharo. So, it appears as if this may be an issue with text (/encoding?). Any ideas? Thanks Otto

The cool implication of gtDocumentor gluing examples and how we might augment source naviagation
by Tim Mackinnon June 26, 2018

June 26, 2018

Hi guys - not sure how many people noticed this, but at the end of the tutorial for gtDocumentor, there is a section on Examples as Documentation. What is neat (and easily missed) is how when an example references another - there is a little triangle you can toggle to expose that example inline. (See photo). This isnât a completely new ideas (didnât Newspeak hopscotch do this?) but its very well done in gtDocumentor and this implication could be that if our code editors had this too - then its very handy to unfold code to understand it in one place without having to open new windows. (I still think there are times when you may want to do that - particularly for long chains of methods?) but its certainly an idea that I would be very receptive to having in our code browsers (heck - give me all of gtDocumentor in our source editors). Iâm wondering what others thing of this? Perhpas not for Pharo 7 - but Pharo 8 (pretty please?) Tim p.s. Note to @feenk, as its the last example its incredibly tricky to expand it to actually see it well as you canât scroll further down to then drag the window bigger. I had to add a lot of Crâs to make some space to do this.
