Problem with gitfiletree numeration
by Mariano Martinez Peck Jan. 14, 2016

Jan. 14, 2016

Hi guys, I wanted to know how you manage this situation. I had my already existing project in shub repo. Last version was OSSubprocess-MarianoMartinezPeck.43. I then created a github repo, cloned it, and then with gitfiletree I commit for the first time. The problem is that the commit I did with GitFileTree received this MC version: OSSubprocess-MarianoMartinezPeck.1. Normally I would not care. But in this case I do care because every in a while I would like to move/publish some versions from github to shub. And OSSubprocess-MarianoMartinezPeck.1 has 2 problems: 1) It has an older version number but newer contents 2) It's number is not unique. So if I copy versions created from github to shub, they would override those versiones created in shub (like the very old OSSubprocess-MarianoMartinezPeck.1 from shub) ?? How do you normally solve this? Thanks! -- Mariano http://marianopeck.wordpress.com

Right to Left languages and fonts
by Jimmie Houchin Jan. 13, 2016

Jan. 13, 2016

Hello, I briefly tried to copy/paste, read from file, some Hebrew text. I simply get some strange characters. From a brief search of the archives. I did not find any means of doing a right to left language. I also am not sure how to use a Hebrew font. Font issues would also apply for when I want to use Greek. What would be needed to do right to left and use the right Hebrew font? I believe these issues would also apply to anyone wanting Arabic or any other such languages. The last message I can easily find is in August of 2014. Maybe Pharo isn't the right tool for this job at the moment. But I did want to explore the potential of it being so. Thanks for any help. Jimmie

Hi... I am totally dumb today or what?? I am trying to load: Metacello new baseline: 'OSSubprocess'; repository: 'github://marianopeck/OSSubprocess:master/repository'; load. And I am getting this error: However, I am getting this error: File Not Found: 'File @ /Users/mariano/Trabajo/PharoConsortium/imagenes/github-cache/marianopeck/OSSubprocess/master/marianopeck-OSSubprocess-18ae52f/repository/OSSubprocess-Tests.package/monticello.meta/version' And doing a ls i get: ls -la /Users/mariano/Trabajo/PharoConsortium/imagenes/github-cache/marianopeck/OSSubprocess/master/marianopeck-OSSubprocess-18ae52f/repository/OSSubprocess-Tests.package/monticello.meta/ -rw-r--r-- 1 mariano staff 55 Jan 13 14:03 categories.st -rw-r--r-- 1 mariano staff 0 Jan 13 14:03 initializers.st -rw-r--r-- 1 mariano staff 27 Jan 13 14:03 package There is no 'version' file as this guy is trying to load.

I will rename FFI-NB to UnifiedFFI
by Esteban Lorenzano Jan. 13, 2016

Jan. 13, 2016

Hi, People has pointed (and they are right) that the name of the new FFI front-end is misleading. So yesterday I was talking with Stef and we think UnifiedFFI (or UFFI, for short) is a better nameâ¦ and to keep packages prox. to regular FFI I was thinking on rename FFI-NB packages to FFI-Unifiedâ¦ but maybe is better just to rename them as UFFI or UnifiedFFIâ¦ what do you think?

Metacello: wrong version if we load twice the same configuration
by Ferlicot D. Cyril Jan. 13, 2016

Jan. 13, 2016

Hi, In some Synectique images we have some problem because we load a project into an image and this project depend on another project (SynMoose) that is already in some of our images in Jenkins. The problem is that a package that we do not want is loaded. SynMoose load the stable version of Magritte3, which depend on MagritteGlamourForPharo40 1.0. The first time we load it, it fetch the version 1.0, which is right. But if we load it a second time (For example when a project depend on it), the version 1.1.0 of MagritteGlamourForPharo40 is loaded. You can see it with this script: Gofer new url: 'http://smalltalkhub.com/mc/Magritte/Magritte3/main'; package:'ConfigurationOfMagritte3'; load. Transcript open. ConfigurationOfMagritte3 load. 3 timesRepeat: [Transcript cr]. ConfigurationOfMagritte3 load. Is it a problem of Metacello? Is it a know problem? Or is it something expected? I think that if we load 2 time the exact same version, the second should do nothing. -- Cyril Ferlicot http://www.synectique.eu 165 Avenue Bretagne Lille 59000 France

[Ann] ReadWriteLock
by Denis Kudriashov Jan. 13, 2016

Jan. 13, 2016

Hi. I implemented small package ReadWriteLock http://smalltalkhub.com/mc/Pharo/ReadWriteLock/main. Gofer it smalltalkhubUser: 'Pharo' project: 'ReadWriteLock'; configurationOf: 'ReadWriteLock'; loadStable It is reentral read write lock which described in https://en.wikipedia.org/wiki/Readersâwriter_lock. From the article: An ReadWriteLock allows concurrent access for read-only operations, while > write operations require exclusive access. This means that multiple threads > can read the data in parallel but an exclusive lock is needed for writing > or modifying data. When a writer is writing the data, all other writers or > readers will be blocked until the writer is finished writing. Public API and Key Messages - lock := ReadWriteLock new - lock criticalRead: aBlock - lock criticalWrite: aBlock Implementation based on two semaphores and readers counter. Main difficulty is carefully handle process termination during execution of critical sections. This problem described in Semaphore>>critical: comment. Same approach is used here. But synchronisation logic around two semaphores for reading and writing complicates things very much. No simple way to decompose logic on multiple methods because information about process interruption become hidden. >From the Semaphore comment: > The main trick is assignment right before we go into the wait primitive > (which is not a real send and therefore not interruptable either). So after > we can check that waiting is happen or not. Tests are implemented only for lock scenarios. No tests for described termination process cases. It is not really clear how to write it. I will be appreciate if people review code. Maybe you will suggest simplifications. It is always difficult to implement concurrent code. Best regards, Denis

ifError: implementation is bad
by Denis Kudriashov Jan. 13, 2016

Jan. 13, 2016

Hi I look at implementation of BlockClosure>>ifError: . I did't know that it culls arguments to errorBlock. But what is this arguments? It is not error instance but specific properties from it. BlockClosure>>ifError: errorHandlerBlock ^ self on: Error do: [:ex | errorHandlerBlock cull: ex description cull: ex receiver] Why people doing that? Many users of it just pass given error like [...] ifError: [:msg :rcv | ... rcv error: msg]. Especially it is commonly used scenario by senders of #critical:ifError:. But it is different question. I propose change ifError: to cull error instance. What you think? Can be put it in Pharo 5? Such change can touch some packages
