#1487: isEmpty() from ObjC ----------------------------------+----------------------------------------- Reporter: iloveitaly@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: ----------------------------------+----------------------------------------- I have this function in objc: {{{ static inline BOOL isEmpty(id thing) { return thing == nil || ([thing respondsToSelector:@selector(length)] && [(NSData *)thing length] == 0) || ([thing respondsToSelector:@selector(count)] && [(NSArray *)thing count] == 0); } }}} From an objc class, if I run: {{{ NSString *a = @"testing"; isEmpty(a); }}} I get the following error from macruby: {{{ rb_main.rb:38:in `<main>': can't convert Class into String (TypeError) }}} This is caused by the specific line in isEmpty(): {{{ [(NSArray *)thing count] == 0) }}} I think that has something to do with: {{{ $ macirb irb(main):001:0> a = "testing" => "testing" irb(main):002:0> a.respondsToSelector :count => 1 irb(main):004:0> a.count ArgumentError: wrong number of arguments }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/1487> MacRuby <http://macruby.org/>

[MacRuby] #1481: spec:ci is really unreliable

#1481: spec:ci is really unreliable ------------------------------------+--------------------------------------- Reporter: mrada@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: ------------------------------------+--------------------------------------- Running the full spec suite ranges from unreliable to impossible for people trying to make contributions to MacRuby. The usual symptom is that MacRuby will crash at some point, possibly more than once, during the suite and the suite will never finish. There are reports on the mailing list, see "[MacRuby-devel] 'rake spec:ci' causing crash (built from HEAD)" and I personally have a hard time running "spec:ci" due to crashes and end up running some subset of the full suite related to what I am working on. This is a major barrier to contributing to MacRuby, especially since being able to run the test suite is part of the build instructions. -- Ticket URL: <http://www.macruby.org/trac/ticket/1481> MacRuby <http://macruby.org/>
