Thanks! -r By: Piotr Szotkowski RE: Memory leaks with ruby-prof 0.6.0 on Ruby [ reply ]   2009-11-21 13:07 I’m not 100% sure whether there’s a single answer, but I’d go with ‘yes’. The problem of using ruby-prof on 1.9 is that the svn checkout does not work (requires a patch from the Redmine), and there are two GitHub forks: one does not aggregate the calltree results (so you end up with thousands of entries like Set#&-1138), while the other takes incredible amount of time to aggregate the results (like 50x runtime). By: Roger Pack RE: Memory leaks with ruby-prof 0.6.0 on Ruby [ reply ]   2009-11-20 18:23 Was this leak resolved? -r By: Piotr Szotkowski RE: Memory leaks with ruby-prof 0.6.0 on Ruby [ reply ]   2008-04-15 08:04 This is the code behind my PhD, so I have to clear with my advisor whether I can open source it before sharing with ruby-core, but I’ll definitely let the list know either way. By: Charlie Savage RE: Memory leaks with ruby-prof 0.6.0 on Ruby [ reply ]   2008-04-15 07:33 Hi Piotr, Thanks for following up on this. Have you let the Ruby core mailing list know about this? By: Piotr Szotkowski RE: Memory leaks with ruby-prof 0.6.0 on Ruby [ reply ]   2008-04-13 19:48 I tested and it seems Ruby 1.9.0-1 suffers from the same memory leaks. :( By: Piotr Szotkowski RE: Memory leaks with ruby-prof 0.6.0 on Ruby [ reply ]   2008-04-12 19:29 I just ran some more tests and it seems the leak is most probably in Ruby itself: Ruby 1.9.0-0 leaks very much in comparison to Ruby 1.8.6p111 running the same script. I’ll test with Ruby 1.9.0-1 in the coming days and report back (but it’s most probably not a ruby-prof issue). By: Charlie Savage RE: Memory leaks with ruby-prof 0.6.0 on Ruby [ reply ]   2008-02-14 21:00 Hi Piotr, Thanks for the report. I forwarded it to Shugo to take a look since he's the one who worked on the Ruby 1.9 port. By: Piotr Szotkowski Memory leaks with ruby-prof 0.6.0 on Ruby 1.9 [ reply ]   2008-02-14 18:28 (This is a repost from ruby-talk – I didn’t get any replies there, unfortunately.) I’m running into memory leaking issues when trying to profile my code with ruby-prof 0.6.0 on Ruby 1.9. Two scenarios, in which 1.8 is Ubuntu’s packaged Ruby 1.8.6.p111, while 1.9 is hand-compiled Ruby 1.9.0.r14709. ruby-prof 0.6.0 from RubyGems in both cases. Memory usage reported with the proprietary, highly scientific method of Looking at Live Htop Changes in Memory Usage for the Whole System™. Times are time’s real/user, the ruby-prof’s printer is graph_html. Ruby 1.8: * the code ran with plain Ruby executes in 1m41s/1m22s, the memory consumption stays below 300 MiB. * the code ran with ruby-prof executes in 4m35s/2m49s, the memory consumption stays below 320 MiB. Ruby 1.9: * the code ran with plain Ruby executes in 0m30s/0m30s, the memory consumption stays below 310 MiB. * the code ran with ruby-prof executes in… well, I stopped the execution when the memory consumption passed my laptop’s 1 GiB and made a 350 MiB dent at my temp partition. Are there any known memory issues with ruby-prof 0.6.0 on Ruby 1.9? Unfortunately, the code under profiling being the code behind my PhD, I can’t currently open source it (I will once my research is complete); I can send it to people off-list (provided it doesn’t get shared further). Thanks in advance for any comments/ideas.
