It seems that building the Melbourne extension for MRI (as part of regular build) will use flags from the MRI installation, which can cause an issue if trying to build Rubinius on a different version of GCC. For example, a MRI built on GCC 4.0.1 may (will?) have -arch in its flagset, and this will cause an error on GCC 4.3+.

The workaround is to either use the same or non-conflicting GCC to build Rubinius (set $CC and $CXX), or then to first build Melbourne and then rbx:

$ CC=whatever rake extensions:melbourne_mri
$ rake build

Original:

GCC 4.0 (at least) works fine. Workaround is to set the compiler with CC and CXX.

Investigate whether it is really necessary to add the arch flag at all and either remove it or improve detection to only use it when appropriate.

Howdy, I just installed RC1 to check compatibility with FakeWeb. I got a bunch of errors in our test suite because OpenSSL::SSL seems to be missing. Is the OpenSSL implementation incomplete? Or is there something wrong with my installation?

The JIT should detect that a function is taking too many uncommon exits and deoptimize it.

My build failed because I didn't have readline.h installed. Simple to fix, but there's no indication what's wrong because the GCC output is piped to /dev/null, and ./configure should be checking for its presence.

Whenever I run rake in the project directory, it fails on rakelib/vm.rake:195 with an undefined method 'each' for nil:NilClass error.

it runs fine in both 1.8 and 1.9, This could be a rspec issue since it doesn't check if it's trying to delete out of bound index from a array.

Problem file ~/.rvm/gems/rbx/head/gems/rspec-1.2.9/lib/spec/runner/option_parser.rb

Evan's comment:

I investigated this a bit more today. The fix is to, when vcall is normalized, remember that it was a vcall in some way.

That way, we can only check for a local variable override where a vcall was used. This is tricky right now, because adding things to the sexp form blows up the compiler, since it's using .last for a number of things related to inspecting a call sexp (and expecting an s(:arglist...))

I tried to add a @style instance variable to the sexp, but it never makes it all the way through the pipeline, I'm assuming due to the sexp being pulled apart and rebuilt, which looses the ivars.

LH 522 reported by manveru.

I found that there is a different behaviour in rubinius for local variables assigned in a block.

# Ruby 1.8:
10.times{ bar = 1 }; bar
#=> NameError: undefined local variable or method `bar' for main:Object

# Rubinius
10.times{ bar = 1 }; bar
# nil

According to evan, the following sexp has to change.

pp "10.times { bar = 1 }; bar".to_sexp
[:block,
 [:newline,
  1,
  "(eval)",
  [:iter,
   [:call, [:lit, 10], :times],
   nil,
   [:block,
    [:dasgn_curr, :bar],
    [:newline, 1, "(eval)", [:lasgn, :bar, [:lit, 1]]]]]],
 [:newline, 1, "(eval)", [:lvar, :bar, 0]]]

that should read

pp "10.times { bar = 1 }; bar".to_sexp
[:block,
 [:newline,
  1,
  "(eval)",
  [:iter,
   [:call, [:lit, 10], :times],
   nil,
   [:block,
    [:dasgn_curr, :bar],
    [:newline, 1, "(eval)", [:lasgn, :bar, [:lit, 1]]]]]],
 [:newline, 1, "(eval)", [:vcall, :bar, 0]]]

so the :lvar on the last line becomes :vcall

The second optional argument of Regexp.new can be used to indicate the language/encoding.

The default behavior:

re = Regexp.new(".")
str = "中文" # or "\344\270\255\346\226\207" in utf-8 encoding
re.match(str)[0] # => "\344"

When specifying the language/encoding:

re = Regexp.new(".", nil, 'u')
str = "中文" # or "\344\270\255\346\226\207" in utf-8 encoding
re.match(str)[0] # => "\344\270\255"

However, there's a global variable $KCODE that indicate the current language/encoding. When set, the regexp should behavior according to this, thus:

$KCODE = 'u'
re = Regexp.new(".")
str = "中文" # or "\344\270\255\346\226\207" in utf-8 encoding
re.match(str)[0] # => "中" or  "\344\270\255" in utf-8 encoding

Those are Ruby 1.8 behavior. Since Ruby 1.9 gains full Unicode support, the global variable $KCODE is no longer used. I think Rubinius is currently making capability mainly to Ruby 1.8, so this should be considered.

One way to fix this, I think, is to change the default value for the second optional argument (lang) of Regexp.new from "nil" to "$KCODE".

I don't know whether Rubinius and Ruby1.8 use the same regexp engine. But it seems that even though I set $KCODE to 'u' in Ruby1.8. The code

Regexp.new(".").inspect

will return "/./" but

Regexp.new(".", nil, "u").inspect

returns "/./u" . However, the "/./" can successfully match a multi-byte character when setting $KCODE to 'u', but fails in Rubinius. So I think maybe some better way is to patch the regexp engine to take care of the global variable instead of patch the Regexp.new method.

Paraphrasing: "gettimeofday" is used in various places. This could possibly cause timing problems if the system date is changed between the uses.

(I don't know if this is an issue.)

Suggested fix:

I find that "get_clock" in libev's "ev.c" is a good implementation but it is not exported in "ev.h". It would be nice if libev would also export it's cross-platform timers independently.

Multiplexing different types of events on Channels is presently pretty difficult, to the point that IO#select cannot be implemented.

Evan threw out the idea of event objects. These could hopefully store any data resulting from I/O completions, the source of the I/O event, or completely non-I/O related things as not all events are I/O related, such as timeout events.

Event objects could abstract interaction with scheduler directly, e.g.:

te = TimeoutEvent.perform chan, 5.0, value
re = ReadEvent.perform chan, io, 4096, value

(where value is an optional user-specified parameter)

when the event occurs, a corresponding Event object is written to the channel, which would include the event type through the nature of its class, and also provide accessors for the event source, any data that may have resulted from the event (e.g. data read from an IO object), and the user value, if it was specified.

This would make for easy case-based processing of IO events, e.g.:

ev = chan.receive
case ev
when ReadEvent then read_handler(ev)
when WriteEvent then write_handler(ev)
when TimeoutEvent then timeout_handler(ev)
... end

Greetings, I sent below to rubinius-dev mailing list but it didn't show up in google group, so I re-post them here.

Sorry if it's wrong place to post here.

I am not (yet) digging into source code,
and I guess IncludedModule was created
for separating each included module.
For example:
http://gist.github.com/30606 (first one or below)

module M
 def m
 end
end

module K
end

class C
 include K
end

module K
 include M
end

C.new.m # => undefined method

class D
 include K
end

D.new.m # => nil
C.new.m # => undefined method

Things are different in Kernel, because there's no
IncludedModule for Kernel in superclass_chain:
http://gist.github.com/30606 (last one or below)

module M
 def m
 end
end

module Kernel
 include M
end

class C
end

C.new.m # => undefined method

class D
 include Kernel
end

D.new.m # => nil
C.new.m # => nil in Rubinius
# undefined method in MRI 1.8/1.9 and JRuby

Should there be (an) IncludedModule(s) for Kernel?

Thanks and cheers,

I can't reproduce the failure when running a file with the same code.

Assigning to already defined constants gives unexpected behaviour or even segmentation faults. I have built from latest git. Examples:

String = nil
puts "foo"
=> Segmentation Fault

String = nil
class String; end
=> Segmentation Fault

Array = nil
puts "foo"
=> (Nothing gets printed)

Array = nil
class Array; end
=> (Nothing happens)

Fixnum = nil
puts 42
=> 42

Fixnum = nil
class Fixnum; end
=> Fixnum is not a class (TypeError) with backtrace: Exception occurred during top-level exception output! (THIS IS BAD)

In all of this, Fixnum seems to behave most correctly. I haven't tried any other constants.

i tried installing the rjb gem without installing rubinius (that is, running rbx directly after 'rake'. i didn't install since that did not succeed, see another issue)

bin/rbx gem install rjb-1.1.6.gem --no-rdoc --no-ri Building native extensions. This could take a while...
ERROR: Error installing rjb-1.1.6.gem:

Since @subclasses stores the list of classes that are inherited, the class definition will not be garbage collected due to being referenced in this list.

This is what happens sometimes during a gem install:

I haven't been able to reproduce this reliably, if i can get more information out of it, I'll add it to this issue.

Initially the CPU is pegged at ~180% and slowly drops to ~100% which leads me to think there's more than one thread eating CPU at first.
It also continuously eats RAM slowly (I think it's around 500k-1MB/sec or so) until it finishes or I kill it. I've left it running for over 15min before killing it, and hadn't installed a single gem in that time.

This is a bug for the website http://rubini.us/community.html (couldn't find a bug report area for the website).

On the above page the last sentence "always be able to answer questions–all we ask" contains an invalid character in the word "questions". Perhaps someone copy and pasted from a text editor like Word?

The following BasicSocket#getsockopt spec fails consistently since the specs tags were updated last night. Given that it doesn't fail when boyscout runs it, I'm guessing it's a platform issue.
