Pharo6 server deployment and no home directory

by Holger Freyther

Hi, as Pharo6 is around the corner I have moved my CI build from tracking Pharo5 to Pharo6 but I run into a problem. Either if $HOME is not set at all or $HOME points to a wrong directory I run into the error below. As this is a server application and I run multiple VMs with the same image and there is no home directory I would prefer that no information is persisted at all. Can this be done? Have there been any changes in Pharo6 in regard to this? It also seems to change from Fuel->Ston for the identifier? Is this intended? holger HOME=/home/blabla ./vm/pharo --nodisplay My.image eval --save '(NonInteractiveTranscript onFileNamed: #stdout)' install PrimitiveFailed: primitive #createDirectory: in UnixStore failed UnixStore(Object)>>primitiveFailed: UnixStore(Object)>>primitiveFailed UnixStore(DiskStore)>>createDirectory: UnixStore(FileSystemStore)>>ensureCreateDirectory: UnixStore(FileSystemStore)>>ensureCreateDirectory: UnixStore(FileSystemStore)>>ensureCreateDirectory: FileSystem>>ensureCreateDirectory: FileReference>>ensureCreateDirectory FileLocator(AbstractFileReference)>>ensureCreateDirectory GlobalIdentifierFuelPersistence(GlobalIdentifierPersistence)>>ensureDirectory GlobalIdentifierFuelPersistence(GlobalIdentifierPersistence)>>save: GlobalIdentifierFuelPersistence(GlobalIdentifierPersistence)>>load: GlobalIdentifierFuelPersistence(GlobalIdentifierPersistence)>>ensure: GlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>ensure: GlobalIdentifier>>ensure GlobalIdentifier class>>initializeUniqueInstance GlobalIdentifier class>>uniqueInstance SystemSettingsPersistence class>>resumeSystemSettings [ :persistence | persistence resumeSystemSettings ] in PharoCommandLineHandler>>runPreferences in Block: [ :persistence | persistence resumeSystemSettings ...etc...

I tried but I can't reproduce the case with dummy code. I can share privately an image though. Hilaire Le 14/04/2017 Ã 15:24, Denis Kudriashov a Ã©crit : > > Could you create example set of packages to reproduce problem? (to be > not dependant on your private code) > -- Dr. Geo http://drgeo.eu

Tested on Pharo6, result is the same :( Traits logic is lost when saving the package.

Traits score: Squeak: 1, Pharo5: 0

by Hilaire

So it looks like Squeak[1] is capable to produce a correct .mcz file, out of a package coming with Traits and class. By correct, read the Traits logic is not lost. Hilaire [1] I tested with a Squeak6 alpha waiting somewhere on my disk -- Dr. Geo http://drgeo.eu

[ANN] Prometheas : a Pharo wiki database

by Dimitris Chloupis

Part of my Discord bot as a goal was to add the ability to create database entries so that people can quickly find documentation. It was quite a challenge for me because I had to learn how heroku works, PostgreSQL and all the other things but I did it!!! In any discord channel you have now 3 commands !doc , !docadd , !docremove 1) !doc <search_term> search for a term in the documentation database eg. !doc pharo 2) !docadd <search_term> <content> <tags> <links> add a new entry to the documentation database eg. !docadd "pharo" "Pharo is a modern implementation of Smalltalk" "{'smalltalk','live coding','language'}" "{'squeak','IDE'}" 3)!docremove <search_term> remove a term from database eg. !docremove pharo tags , is for more complex searches in the future, links for sending users to relevant documentation I am also planning to give access to pharo users to the database from inside the pharo image, if its easy enough to use PostgreSQL from inside Pharo. Currently the bot is fully coded in python. The goal is not to create a full documentation but rather quick help tips for fast pointing to the right direction. This is also an invite to experience pharo devs and newcomers to start adding to this database. The database is PostgreSQL , one of the most populars, I have nothing against MongoDB , its just that it works better with heroku where I host the database. But if in the future find a way to do it for free I can move to MongoDB, but no promises. Anyway this was an excuse for me to learn database programming that I had abandoned 25 years ago (DBASE). So have fun with this :)

Re: [Pharo-users] Traits, method flatten

Ah, no my bad. Squeak was file in correctly the Trait and Class, it is just that its browser does not let you know if a method class belong to one of its Traits or the class itself Le 14/04/2017 Ã 11:16, Hilaire a Ã©crit : > Give a try to filein the correct .st source file of the Traits+Classes > package.
