[ANN] TCS 1.9.3-p179 experimental build Jon 4/13/12 1:11 PM
TCS Ruby 1.9.3 => MRI 1.9.3 performance optimizations for Windows and *nix users.

*nix users can try out TCS improvements thanks to Yura's multi-platform optimizations and his 1.9.3 backport of the COW-friendly, Bitmap Marking MRI 2.0.0 GC. Simply use your good friend RVM or rbenv to get started...and tell Michał Papis, THANK YOU.

  https://github.com/thecodeshop/ruby/wiki/FAQ#wiki-rbenv

Windows users can download the binary archive `tcs-ruby193_require_fenix_gc_hash_20120413.7z` built from the https://github.com/thecodeshop/ruby/tree/tcs-ruby_1_9_3 branch from https://github.com/thecodeshop/ruby/wiki/Downloads

Thanks to Hiroshi's and Luis' continued efforts, Fenix (aka faster `File.expand_path` from a Window's API implementation) is fully integrated and enabled by default. You'll should see faster rails startup times and faster requires.

While the existing ruby-core test suite passes when building on both Windows and *nix, we may discover issues that require further Fenix refinements. That said, I'm burning the boats and fully committing to integrating Fenix for future TCS releases.

Finally, for those using TCS Ruby 1.9.3, let us know how its working for you. Blog it. Tweet it. Share it. If you like the optimizations and want them in a future official 1.9.3, advocate for them with ruby-core.

We'll continue the hard work of maintaining 1.9.3 pre-backports for all the optimizations ;)


=== Notable Updates from Previous Release ===

  * Yura's trunk-accepted Hash opts and new spinlock protected pool allocation
  * Yura's expanded_path update to his cached $LOAD_PATH optimization
  * Hiroshi's fileload, Fenix tweaks, and Fenix integration optimizations
  * Official ruby-core 1.9.3 backports as of ruby_1_9_3@35295
  * OpenSSL 1.0.0h (Windows binary)
  * RubyGems 1.8.21 (Windows binary)

There's no need to have RUBYOPT -rfenix/replace anymore? :) That's awesome! Thanks!

Don't know if a pre built gem will work out of the box like this one, specially due FD_SETSIZE added to rubyinstaller recipe.

Sorry for top posting. Sent from mobile.

On Win7 32bit, I get the same segfault when running on plain vanilla 1.9.3p179

C:\Users\Jon>ruby -reventmachine -ve "puts EM::VERSION; EM.run {}"

But I don't see a SEGV on the official released 1.9.3p125

Might be related to FD_SETSIZE, need to investigate since it will affect all the existing pre compiled binaries.

According to these comments, unmatched FD_SETSIZE seems to cause segfault.

I tried to build eventmachine with this patch. eventmachine started
without segfault, but crashed after Ctrl-C.

I can't find any reference to these issues on the web. In theory, if
Ruby was build with FD_SETSIZE bigger than what EventMachine is using,
it will only affect the number of file descriptors from fd_set it will
iterate over using select():

http://support.microsoft.com/kb/111855

And shouldn't segfault as fd_set contains a counter with the number of FD in it.

I'm investigating this right now, FD_SETSIZE seems also affect Ruby:
http://bugs.ruby-lang.org/issues/6228

Worth to mention an issue that might sound similar from Python:

http://bugs.python.org/issue12287

checking if FD >= FD_SETSIZE

Will be we could do a debug build of both ruby and eventmachine and
get this through GDB.

gdb (on plain vanilla 1.9.3-p179 built with RubyInstaller's -DFD_SETSIZE override) says it can't access the memory location when dereferencing a pointer in win32/win32.c:2715....

Until we fix root cause, I've yanked the original Windows binary archive and replaced it with a new version (tcs-ruby193_require_fenix_gc_hash_20120413-2.7z) built *without* -DFD_SETSIZE.  The new version doesn't SEGV on my Win7 32bit machine with EM.

Download from: https://github.com/thecodeshop/ruby/wiki/Downloads

Jarmo...THANK YOU for testing so quickly...let us know how the new version works.

It seems to be working now :)

Thanks!

I don't understand why this old thread came alive :) For some reason google sent me an e-mail about the update done by Jon in 14th of April. The problem is solved long time ago.
