#446: Dispatch::TIME_FOREVER too big for signed long long -------------------------------+-------------------------------------------- Reporter: niklas@… | Owner: lsansonetti@… Type: defect | Status: new Priority: minor | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: gcd semaphore long long TIME_FOREVER -------------------------------+-------------------------------------------- Dispatch::TIME_FOREVER is 18446744073709551615 so it fits into a unsigned long long. When you call "wait" with TIME_FOREVER on a semaphore the function in gcd.h (l. 826) uses NUM2LL(time) to convert the time in to a signed long long which leads to {{{ core:in `wait:': bignum too big to convert into `long long' (RangeError) from untitled:1:in `<main>' }}} I've seen this in MacRuby 0.5 beta 2 -- Ticket URL: <http://www.macruby.org/trac/ticket/446> MacRuby <http://macruby.org/>

memory leaks
by Jakub Suder 06 Jul '10

06 Jul '10

Hi, The users of my app are reporting to me that it takes way more memory than such app is supposed to. I've just released a new version that was supposed to improve this at least a bit, and someone commented that "I haven't even entered login and password and it already leaked almost a megabyte" (posting this screenshot from Instruments: http://static0.blip.pl/user_generated/update_pictures/1129697.jpg) I did a test - I've removed almost everything from the app except the login screen; and indeed, when started, the Leaks tool in Instruments shows about 800 KB of leaked memory (I suppose it goes up over time). All of that is shown as coming from libmacruby (though this really just means that the app is running MacRuby, as I understand). Now, I'm wondering: - is this memory leaking because I'm doing something wrong (though there's not much things I could have done wrong in a login dialog...) - or is it leaking because MacRuby is doing something wrong - or is it not leaking at all really, and it's just that Instruments can't understand the memory managed by MacRuby and assumes it's leaked even if it's not? Here's a minimal version of the app: http://dl.dropbox.com/u/41808/macblip_mem_test.zip Could you take a look and give me some clues? (I'm running MacRuby 0.6 stable) Best regards, Jakub Suder
