simulator spotted a small problem with initializing stdout for the CommandLineHandler
by Eliot Miranda April 2, 2014

April 2, 2014

Hi Camillo, ClÃ©ment and I are simulating Pharo for Sista and I've spotted the following small problem with the BasicCommandLineHandler's use of stdout. It looks like a bug in MultiByteFileStream>wantsLineEndConversion:. BasicCommandLineHandler>>initializeStdout sets stdout's line end conventuion, but in doing so MultiByteFileStream>wantsLineEndConversion: sends MultiByteFileStream>detectLineEndConvention, which is wrong, because stdout is write-only. I needed to change the simulator to fail as the VM does, but perhaps a better fix is not to try and read from write-only streams. Anyway, thought I'd point it out. No biggie. 16r101B18 M MultiByteFileStream>detectLineEndConvention 16r1F3A7A0: a(n) MultiByteFileStream 16r101B38 I MultiByteFileStream>wantsLineEndConversion: 16r1F3A7A0: a(n) MultiByteFileStream 16r101B60 I BasicCommandLineHandler(CommandLineHandler)>initializeStdout 16r1F3A654: a(n) BasicCommandLineHandler 16r101B84 I BasicCommandLineHandler(CommandLineHandler)>initialize 16r1F3A654: a(n) BasicCommandLineHandler 16r101BA4 I BasicCommandLineHandler>initialize 16r1F3A654: a(n) BasicCommandLineHandler 16r101BBC M BasicCommandLineHandler class(Behavior)>new 16r5B04CC: a(n) BasicCommandLineHandler class 16r101BD4 M [] in BasicCommandLineHandler class>startUp: 16r5B04CC: a(n) BasicCommandLineHandler class -- best, Eliot

Re: [Pharo-dev] New Nautilus side bar buttons

Anyway, it will be friday 18hs to 20:30hs, in this place: http://www.cervelar.com.ar (in the Belgrano location). If you are in Buenos Aires and want to come, please send a confirmation (we need to make a reservation). Cheers, Esteban

PharoVM on Windows & Code::Blocks for debugging
by phil＠highoctane.be April 1, 2014

April 1, 2014

I'd like to know if someone managed to get Code::Blocks to work with the MinGW configuration. I've the build running from the command line. I can also configure C::B to use makefiles. Now, there seems to be some glitches and was curious to know if someone had a working setup. (Yes, one can use gdb in the command line mode, but it is ugly. And TUI doens't work on Windows). There are many interesting pieces of code in the Windows platform code. And I'd like (at one point) to have a real headless Pharo.exe There are also the pieces to get the Pharo.exe run as a service natively. I've been studying this with SourceNavigator and done basic gdb work. But for larger work, I'd like to have a decent IDE. NOTE: my email appears to bounce on the vm-dev list, please someone help me sort that out. Phil

Will Nautilus scrolling bug be fixed for Pharo 3.0 release?
by Marco A. March 31, 2014

March 31, 2014

Occasionally, when I use my trackpad to scroll through my classes (the 2nd column in the Nautilus window), the package pane starts scrolling (1st column) even though the cursor has never moved outside of the left-and-right bounds of the 2nd column. I looked in read-only Pharo-issue tracker via Penelope http://bugs.pharo.org/ in the Cases for UI to see if someone had already reported this but found that the last post there was March 2013. Although I'm trying to learn enough to be able to contribute, I think fixing this is out of my reach for now. I inspected the Nautilus class but got stuck trying to see how mouseMoved events were sent and handled to the Nautilus window. Do you think this will be fixed for the Pharo 3.0 release? - Marco A.

Fwd: CodeCritics command line
by Yuriy Tymchuk March 31, 2014

March 31, 2014

Hi guys. Maybe someone can help me before I waste a lot of time. It looks like on August 29 something changed in Code Critics API and after that the command line tool is not capturing all reports. Cheers.

Something is not working for me. When I use the code critics browser, and run it on the whole system I get (for example) RBVariableReferencedOnceRule 90 violations, while command line tool gives me only 3. And this happens with all of the rules (command line tool always reports very few). Maybe you have a clue what can be a problem, because Iâve spent a day already without any success. > > Cheers. > Uko >

threading in Pharo
by Alexandre Bergel March 31, 2014

March 31, 2014

Hi! Threads in Pharo have always been mysterious for me. If I doit the following: [ true ] whileTrue Can other thread interrupt this? Say in other words, can the following piece of code may suffer from a concurrent problem in Pharo anOrderedCollection add: 42 My current understanding about thread is that there is a scheduling that may occurs each time we enter the VM (e.g., primitive call, instantiating an object, throwing an exception). So, the code "anOrderedCollection add: 42â will _never_ suffer from concurrent call because adding 42 to a collection does not enter the VM. Does this make sense? What is the current status of this? Thanks to you all Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
