#216: fork subprocess exiting (normally) segfaults -------------------------------+-------------------------------------------- Reporter: celtic@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: fork process -------------------------------+-------------------------------------------- When '''fork''''s subprocess dies, it segfaults about 80% of the time (out of a sample of 10 runs): {{{ echo "fork {}" | macruby }}} Calling the non-block version alone like this seems to segfault less often, perhaps 50% of the time: {{{ echo fork | macruby }}} Note that it's only the subprocess that segfaults, and not the main process. This can be demonstrated: {{{ fork { } sleep 1 puts "soup" }}} This produces the segfault output, followed by 'soup' a moment later. Strangely, sleeping after the non-block call causes things to work: {{{ fork sleep 1 }}} (no segfault with the above code) -- Ticket URL: <http://www.macruby.org/trac/ticket/216> MacRuby <http://macruby.org/>

#159: "%d" with large integer argument gives conversion error ---------------------------------+------------------------------------------ Reporter: jamis(a)37signals.com | Owner: lsansonetti(a)apple.com Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: ---------------------------------+------------------------------------------ The following script reproduces the error easily: {{{ N = 34363859232 p N p N.class puts "%d" % N }}} This results in the following exception: {{{ 01.rb:5:in `%': integer 34363859232 too big to convert to `int' (RangeError) }}} When run in ruby 1.9, the output shows that N is a Bignum. When run in macruby, the output shows that N is a fixnum. This appears to be due to bignum.c line 523: {{{ if (len <= (sizeof(long)*CHAR_BIT)) { }}} Apparently, in macruby, sizeof(long) is 8, which means bignums are only instantiated for integers larger than 64 bits or so, and in the above example, the integer is only 44 bits. Even though the bignums are only created based on sizeof(long), the rb_str_format function in sprintf.c uses FIX2LONG for converting the VALUE to a long int, and FIX2LONG uses INT_MIN and INT_MAX to check the bounds of the integer. I'm not sure what the safest way to fix this is. Should check_int (and others?) in numeric.c be comparing against larger boundary numbers, instead of INT_MIN/MAX? -- Ticket URL: <http://www.macruby.org/trac/ticket/159> MacRuby <http://macruby.org/>

[MacRuby] #218: including a module which defines functions can mask functions of the same name in the including class

#218: including a module which defines functions can mask functions of the same name in the including class -------------------------------+-------------------------------------------- Reporter: celtic@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: -------------------------------+-------------------------------------------- Simple explanation: classes A and B both define methods `foo', as does module M. A includes M before defining its own `foo', whereas B includes M afterwards. Given that A and B both call `super' in their `foo', it turns out that only A's `foo' ends up calling M's, whereas B's does not. Conclusion: including the module which defines the method after defining ones own causes it to be lost. I believe this is causes the problem first referred to in #215. Attaching a test case which verifies this behaviour. -- Ticket URL: <http://www.macruby.org/trac/ticket/218> MacRuby <http://macruby.org/>
