similar to: Fastthread memory leak?

Well, just when I thought I was out of the fastthread business... Okay, in brief: fastthread is a Ruby extension which re-implements the primitives in Ruby''s thread.rb in C. It was merged into 1.8.6, replacing the old thread.rb implementation, but the version that was merged had a couple serious bugs. So -- now I release fastthread 1.0, which is basically the Ruby 1.8.6 version with

Hello Guys, Been testing fastthread (known on previous releases as optimized_locking) for soon to be released 0.3.18 mswin32 gems (official ones). Attached to this message is the ruby script I used for the test results shown on graphics [1] and [2] The idea of the script is simulate what Mongrel do with threads creating a simple workload for testing Ruby VM stability. [1] refers to normal,

== NOW A new version of fastthread, the library providing better implementations of the classes in thread.rb, has been released. Please note that fastthread is only for Ruby 1.8, not JRuby or any other Ruby implementation (most of them don''t need it anyway!). == WHY The existing implementation of Mutex, Queue, etc. in thread.rb is slow. fastthread''s is faster (and bypasses

Hi, A quick search didn''t explain what fastthread is, and how it relates to mongrel. Why would I want to install fastthread? Thanks, Joe

It looks like I got too creative in 0.6.1 and consequently ran afoul of a bug in the Ruby interpreter. 0.6.2 works around the bug and should be entirely stable at this point. Thanks to Young Hyun for his help in coming up with test cases. == what? fastthread is a Ruby library which provides a faster (and non-memory-leaking) C implementation of the concurrency primitives from stdlib''s

Heya Folks- This is mainly for Zed and Mentalguy. I have been playing with the new release of rubygems 0.9.0.8 and I have a major problem with the requirement that fastthread needs to be required before thread. Just requiring rubygems and then requiring fastthread right after that will throw the error: ez _blog $ ruby require ''rubygems'' require

Hi all, I''d really appreciate some help with this... As you see below, I tried to install mongrel after updating my gems, but I get the error shown: sudo gem install mongrel Select which gem to install for your platform (i486-linux) 1. mongrel 1.0.1 (ruby) 2. mongrel 1.0.1 (mswin32) 3. mongrel 1.0 (mswin32) 4. mongrel 1.0 (ruby) 5. Skip this gem 6. Cancel installation > 1

I''ve just committed fastthread 0.5.3, which finally gives us a working SizedQueue (which hadn''t really ever worked in previous versions). Mostly it was just a matter of refactoring Queue and SizedQueue into a single class behind the scenes, so I could move the signalling of the SizedQueue-specific condition variable inside the queue''s critical section. Failing to do so

I just realized -- if fastthread can be included while Mutex-using code is already running, then the definition and replacement of the classes needs to happen atomically. Otherwise, it creates a race condition where a thread can e.g. end up seeing an incompletely defined Mutex class or none at all. fastthread 0.6.1 addresses this by defining the classes and then atomically swapping the constant

Is anybody testing mongrel on ruby 1.9. I just tried installing mongrel on trunk 1.9 and trunk rubygems and got this error compiling fastthread: /Users/stephen/dev/ruby/1.9_trunk/bin/ruby extconf.rb install mongrel --no-rdoc creating Makefile make gcc -I. -I/Users/stephen/dev/ruby/1.9_trunk/include/ruby-1.9/i686-darwin8.10.1 -I/Users/stephen/dev/ruby/1.9_trunk/include/ruby-1.9 -I.

I''m running jruby trunk which has integrated rubygems 1.0.0 and when I try and install mongrel with gem it blows up when the fastthread dependency tries to do a native compilation. I couldn''t find a copy of the gemspec in the svn checkout but looking at the one installed when gem installing mongrel didn''t show any platform differentiation. There is platform

With Mongrel 0.3.18, I have not seen a single one of the hangs that I have been grousing about for the past N weeks. Thanks MenTaLguY and Zed! Q: Mongrel loads fastthread, Mongrel loads Rails, Rails loads OCI8, OCI8 requires ''thread''. That means OCI8 is using fastthread too, right? Steve

It looks like fastthread was rolled into 1.8.6: http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/tags/v1_8_6/NEWS?revision=12055&view=markup Does that mean once we upgrade to 186 we can forget about rubygem version? - Rob

I was just curious if anyone noticed any significant performance improvements using fastthread (or Ruby 1.8.6) with BackgrounDRb Brandon -------------- next part -------------- A non-text attachment was scrubbed...

I''m confused. Wasn''t threading fixed in 1.8.6, negating the need for fastthread? Why is fastthread still a requirement of Mongrel? Just curious. :)

Just a quick note that I''ve committed the bits for fastthread 0.5; the most important differences are that all the thread.rb classes are once again marshallable, and we''ve got Luis'' commit which eliminates some warnings when building on Win32. -mental -------------- next part -------------- A non-text attachment was scrubbed...

I''ve just committed the makings of fastthread-1.0.2 to SVN, fixing a couple long-standing bugs in 1.0.1: - merged the fix from ruby_1_8 to avoid rb_bugging during exit with waiting threads - SizedQueue#enq is now defined properly Could you or whoever does the signed gems please turn the crank and upload the new gems? Thanks, -mental -------------- next part -------------- A

Hi all, I am strangely getting errors on Debian Etch on a Intel server though I had done an identical install of mongrel-1.0.1 on an amd64 version of Etch. While building fastthreads I get: ERROR: While executing gem ... (Gem::Installer::ExtensionBuildError) ERROR: Failed to build gem native extension. ruby extconf.rb install mongrel creating Makefile make gcc -I.

fastthread is a library which replaces the synchronization primitives defined in stdlib?s thread.rb (Mutex, ConditionVariable, Queue, and SizedQueue) with optimized versions which: * are much faster (in the non-contention case, speed comparable to direct use of Thread.critical or Thread.exclusive) * don?t leak memory (the stdlib implementation of Mutex manages to

I checked out the latest merb ''trunk'' and after installing it as a gem... (fresh install) I got the dreaded "fastthread not loaded: fastthread must be required before thread" error when starting up an instance of merb. Even without dRB. So I patched the merb.rb file to include fastthread before anything else if it''s installed. Check it. Merry Christmas!
