#430: MacRuby does not reap processes started with popen ---------------------------------+------------------------------------------ Reporter: neeracher@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: ---------------------------------+------------------------------------------ in macirb, run the following line: (0..100).each {IO.popen("echo yo") do |f| end} in a separate shell, run "ps -eaf". It will show 100 zombie processes. A source code comparison suggests that MacRuby, as opposed to ruby 1.9, does not call waitpid when popen descriptors are closed. -- Ticket URL: <http://www.macruby.org/trac/ticket/430> MacRuby <http://macruby.org/>

converting UTF-8 to MacRoman still output UTF-8
by Yvon Thoraval 21 Apr '10

21 Apr '10

if i make use of the (pseudo) Iconv : macroman = Iconv.new('macintosh', 'utf-8', str) i found MacRoman is internally 'macintosh' because : puts "CFStringConvertEncodingToIANACharSetName(KCFStringEncodingMacRoman) = #{CFStringConvertEncodingToIANACharSetName(KCFStringEncodingMacRoman)}" gave me : # => CFStringConvertEncodingToIANACharSetName(KCFStringEncodingMacRoman) = macintosh i get back a string (saved to file) still in UTF-8 encoded. then i've read the source of "/Library/Frameworks/MacRuby.framework/Versions/0.6/usr/lib/ruby/1.9.0/iconv.rb" and put some part in a moke-up like that : framework 'Foundation' str = "une phrase accentuée, ça vous va ?" puts str puts "str.size = #{str.size}, str.encoding = #{str.encoding}" def to_macroman(str) data = CFStringCreateExternalRepresentation(nil, str, KCFStringEncodingMacRoman, 0) if data.nil? raise "can't retrieve data from `#{str}'" end dest = CFStringCreateFromExternalRepresentation(nil, data, KCFStringEncodingMacRoman) if dest.nil? raise "can't convert data from `#{str}'" end CFRelease(data) CFRelease(dest) dest.mutableCopy return dest end macroman = to_macroman(str) puts "macroman.size = #{macroman.size}, macroman.encoding = #{macroman.encoding}" File.open("#{SIGNATURES_FOLDER}macroman.txt", File::WRONLY|File::TRUNC|File::CREAT, 0666) {|f| f.print macroman} giving the output : une phrase accentuée, ça vous va ? str.size = 34, str.encoding = UTF-8 macroman.size = 34, macroman.encoding = UTF-8 then i ask why this doesn't convert to MacRoman, as the internal iconv.rb ???? best, Yvon

[MacRuby] #629: Bindings not working for subclass

#629: Bindings not working for subclass ---------------------------------+------------------------------------------ Reporter: dylan@… | Owner: lsansonetti@… Type: defect | Status: new Priority: critical | Milestone: Component: MacRuby | Keywords: ---------------------------------+------------------------------------------ Binding to a property that is overridden by a subclass causes a 'valueForUndefinedKey:]: this class is not key value coding-compliant for the key' error. Expected behavior: binding should call the method on the subclass. I've attached a project that throws this error on launch. The AppDelegate contains Person and Teacher instances. The nib file has a label bound to each. Removing the binding to teacher.name or changing the binding to a property that is not overridden makes the bug go away. I was using an early nightly for beta 0.6. I've also tested with the latest nightly: macruby_nightly-2010-03-06-1240.pkg -- Ticket URL: <http://www.macruby.org/trac/ticket/629> MacRuby <http://macruby.org/>

[MacRuby] #507: valueForKey(key) no longer working with NSManagedObject subclasses.

#507: valueForKey(key) no longer working with NSManagedObject subclasses. -----------------------------------+---------------------------------------- Reporter: johnmacshea@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: valueForKey, KVC, Core Data -----------------------------------+---------------------------------------- In MacRuby 0.4 - any method in an NSManagedObject subclass (or in any other class) could be bound (eg via a controller) to a (view) nscontroller/field. Now - in 0.5 beta 1 and 2 (unless a variable of the same name is a property in the Entity that the NSManagedObject represents) valueForUndefinedKey(key) is called in the subclass, if that method exists, or an error occurs (if valueForUndefinedKey(key) does not exist) - eg: [<Student 0x200391280> valueForUndefinedKey:]: the entity Student is not key value coding-compliant for the key "age". This does not occur in a non NSManagedObject subclass - when view objects are bound to other classes' methods(attributes) - it all works fine. The different version of NSManagedObject valueForKey could be the culprit vis a vis valueForKey in NSObject, but in any case - as mentioned - it worked fine in 0.4. Example project attached. -- Ticket URL: <http://www.macruby.org/trac/ticket/507> MacRuby <http://macruby.org/>

Float bind and NSDecimalNumber
by Daniel Lopes 18 Apr '10

18 Apr '10

Hello, I have a model Person with two accessors, one is initialized as float. In Interface builder I did a bound between accessor and a TableColumn (which one have a NumberFormatter). Everything ok but when I try store in with NSKeyedArchiver.archivedDataWithRootObject it fails saying: *Exception detected while handling key input.* *can't convert NSDecimalNumber into Float* **** -[NSKeyedArchiver finalize]: warning: NSKeyedArchiver finalized without having had -finishEncoding called on it.* * * What I'm doing wrong? I should cast it or initialize the value as NSDecimalNumber instead of float? Thanks.
