#215: OpenSSL's SSLSocket appears not to be initialised correctly -------------------------------+-------------------------------------------- Reporter: celtic@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: openssl -------------------------------+-------------------------------------------- When using net/https, the line to create the new SSLSocket in `connect' fails in OpenSSL::SSL::Nonblock, trying to call @io.fcntl and failing since @io==nil. @io should be being set in OpenSSL's ossl_ssl.c:ossl_ssl_initialize; "ossl_ssl_set_io(self, io)"; but this function appears never to be called! (I tried inserting various rb_warns throughout, before finally just sticking in a call to exit() -- it's not being touched) This appears to be the only place where @io is being set. It disturbs me that the C initialiser is not being run - I am not sure if this is a documented issue or not, or if it's even a MacRuby bug (I'm quite new to all this). This problem can be 'fixed' in the meantime by rewriting SSLSocket#initialize in Ruby-land: {{{ def initialize io, ctx=nil ctx = SSLContext.new if ctx.nil? raise "wrong argument (#{ctx.class})! (Expected kind of SSLContext)" if not ctx.kind_of? SSLContext raise "wrong argument (#{io.class})! (Expected kind of IO)" if not io.kind_of? IO @io, @ctx = io, ctx @sync_close = false @ctx.setup super end }}} ossl_ssl_initialize can be removed from ossl_ssl.c after this. Unfortunately, we just run into another bug in ossl_ssl_setup, which has to do with an SSLContext, trying to work out if it's related now. -- Ticket URL: <http://www.macruby.org/trac/ticket/215> MacRuby <http://macruby.org/>

[MacRuby] #208: Making #binding public returns wrong binding.

#208: Making #binding public returns wrong binding. -------------------------------------+-------------------------------------- Reporter: eloy.de.enige@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- Making the binding instance method of a class public does not return the expected binding. Rather it returns the binding from where the caller. Adding a public instance method which returns its private binding works as expected though. So I'm guessing it goes wrong somewhere in the ‘making a method public’ process. Consider: {{{ class Foo def name "foo" end def b binding end end # untitled:13:in `eval': undefined local variable or method `name' for main:NSObject (NameError) # # p eval("name", Foo.new.send(:binding)) # untitled:17:in `eval': undefined local variable or method `name' for main:NSObject (NameError) # # Foo.send(:public, :binding) # p eval("name", Foo.new.binding) # "foo" p eval("name", Foo.new.b) }}} And here you can see that it in fact returns the binding of the caller, not the Foo instance: {{{ lvar = "lvar" Foo.send(:public, :binding) p eval("local_variables", Foo.new.binding) # => [:lvar] }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/208> MacRuby <http://macruby.org/>

[MacRuby] #172: resurrection error

#172: resurrection error ------------------------------+--------------------------------------------- Reporter: kbenne@… | Owner: lsansonetti@… Type: defect | Status: new Priority: minor | Milestone: MacRuby 0.4 Component: MacRuby | Keywords: ------------------------------+--------------------------------------------- I am trying to use some existing ruby code in my core data document based app. After switching the application over to MacRuby I get a resurrection error upon closing the document's main window and opening a new document. The error is similar to the following: malloc: *** resurrection error for object 0x10f77a0: auto_zone_write_barrier: _NSThreadPerformInfo.argument[32](0x10b04a0)[12] = NSTrackingArea[48](0x10f77a0) I have been able to recreate this problem in a very simple application based on the core data document based application template. The project is attached. I have tested with the 0.3 release and revision 762 in the testing branch. I am not 100% sure if this is a defect in MacRuby or an error in my project. -- Ticket URL: <http://www.macruby.org/trac/ticket/172> MacRuby <http://macruby.org/>
