Hi I love the PharoLauncher. It helps me to manage my parallel development and projects. We should put a link on the Pharo web site because http://files.pharo.org/platform/launcher/ is arcane. Stef

Problem with opening pharo image on macOS 10.12.6. cann't find requested origin: #home. i.e. the script "Smalltalk os current environment getEnv: 'HOME'" failed. (actually The ffiCall from LibC in the method UnixEnvironment>>getEnv: failed ). Is it occurred recently? or issued or fixed in issue tracker already?

Problem loading image after changing resolution from 4Kto HD
by Ted F.A. van Gaalen Dec. 12, 2017

Dec. 12, 2017

Apart from my OSX MacMini, (which has other problems,still, as i wrote about earlier) I also use a PC Windows 10 system mainly for games and doing other awful complicated things like filling out German Tax forms... There is an error depending on resolution. While my PC, Windows 10, is connected to a 4K screen: [ -downloaded Pharo 6.1 from https://pharo.org/web/download -started Pharo with the downloaded vanilla image. -fonts too small to be comfortable readable so changed all to a larger font size (in the image, Appearance) -found the font edges to be a bit blurry on a 4K screen, therefore used this https://imgur.com/7G1sEtz Which lets -as far as i can tell- let the app take care of its dpi scaling. now everything was ok. Font edges where now sharp exactly what I want. -saved the image, thereby overwriting the vanilla image, not using "save as" (this because I want may base image always to contain Seaside and Postgress DB (not yet done here) , mainly because I'd like to make Smalltalk stand-alone apps in a three layer system that is DB<=>Pharo<=>Browser (a web browser is a super nice user interface)) so user-interaction is exclusively over (local)host] later at night, I like to be in gaming (like Eve Online) so the ritual is to disconnect my 4K 3840 x 2160 monitor and then reconnect my PC via HDMI 1920 x 1080 to my TV. This works flawlessly. Windows automagically changes resolution to 1920 x 1080 and even reorders all my desktop icons. Then later, after being a bit bored with gaming, thought of Pharo again, and attempted to reload it, being still in 1920 x 1080 resolution on the TV. then this Pharo window appears: [image: Inline image 1] I then tried to close this System Browser but this didn't work as it emits many windows with errors. Impossible to continue, thus I then closed Pharo *without saving the image*. Later, the next day, when restarting Pharo again in 4K resolution, everything works normally. Could it be that some logic within Pharo does not handle resolution changes correctly? You could try to reproduce this error, using the same procedure as described above.

Installing pharo6.1-64
by T.D. Telford Dec. 12, 2017

Dec. 12, 2017

There are no installation instructions in the README.Â If you execute ./pharo at the top level: pharo6.1-64/vm/pharo: No such file or directory In directory tmp if you add ln -s ../shared/Pharo6.1-64.image Pharo.image and execute ./pharo in tmp, then it works.

Pharo 6.1 / 7, 0 Glorp smalltalkhub to github migration
by Alistair Grant Dec. 12, 2017

Dec. 12, 2017

Hi Everyone, I've migrated Glorp v130, including GlorpSQLite, from smalltalkhub to github using Peter Uhnak's excellent git-migration tool, see: https://github.com/akgrant43/Glorp To load Glorp: Metacello new repository: 'github://akgrant43/Glorp/src'; baseline: 'Glorp'; load. To load Glorp with the UDBC SQLite drivers: Metacello new repository: 'github://akgrant43/Glorp/src'; baseline: 'GlorpSQLite'; load. I'm not familiar with the other drivers, so I'm happy to help, but would like some assistance before migrating the other drivers. If I don't hear any complaints in the next week I'll eventually get around to modifying the ConfigurationOfGlorp on smalltalkhub to use the github version for Pharo 6.1 and 7.0. Older versions of Pharo will continue to load Glorp from smalltalkhub. If there's an official account that should own this project, I'm more than happy to hand it over. Cheers, Alistair

Why do downloads not use HTTPS by default?
by Silent Walls Dec. 12, 2017

Dec. 12, 2017

Today I visited https://pharo.org/gnu-linux-installation-64 to download the zip file containing the executable. To my surprise, the download is not carried out over HTTPS. The download link is http://files.pharo.org/platform/Pharo6.1-64-linux.zip. I ended up downloading the zip file using https://files.pharo.org/platform/Pharo6.1-64-linux.zip. The point is: if HTTPS downloads are supported, why is it not the default on the download pages of the Pharo website?

P3 timeout
by Pierce Ng Dec. 12, 2017

Dec. 12, 2017

Hi Sven and all, I have a PostgreSQL database running in a resource-light Linux VM with ~4 million rows consisting of mostly text. My query executes regexp_matches() on the text and it runs noticeably slowly. I am encountering ConnectionTimedOut using P3 to run my query. PostgresV2 and Python's pg8000 do work though. I see that PostgresV2's PGConnection uses "Socket standardTimeout". I changed ZdcSimpleSocketStream class-side's #openConnectionToHostNamed:port: bottom part to add the same timeout because P3Client>>open calls it: ZdcSimpleSocketStream class>>openConnectionToHostNamed: hostName port: portNumber [...] ^ socketStream timeout: Socket standardTimeOut; "<== added this line" connectTo: hostIP port: portNumber; yourself Now my query returns instead of timing out. It does look like ZdcSimpleSocketStream's three class-side methods could use some refactoring love. Pierce

OSProcess lock image
by Hilaire Dec. 12, 2017

Dec. 12, 2017

Hello, On Pharo4, when I type the command: OSProcess waitForCommand: 'ls' it locks the image, I can get back control with [Alt]-. With the same image and VM, this command was previously working, even called from a Seaside component. Any idea? Thanks Hilaire -- Dr. Geo http://drgeo.eu

Package Discoverability
by Evan Donahue Dec. 11, 2017

Dec. 11, 2017

Hello, I was wondering what the current story was for releasing packages so that they can be discovered. I'm trying to get into the habit of finishing and releasing all those 90% complete projects lying around, and so I wanted to know what the standard process should be for releasing a package of general interest. Especially now that iceberg is a thing, should I make a smalltalkhub page too just for people to search for? Should I submit it to the pharo catalog? Send a note to the mailing list? Any other best practices? Thanks, Evan
