Regexp#named_captures bombs if there are no @names.

This fixes a failing rubyspec test.

http://github.com/josh/rubinius/commit/0418fc10e0c662d883c42791d4b5152fabd52f42

Rubinius segfaults running the following command:
bin/rbx -e "100000000.times { 1 + 1 }"

Error messages are described here: http://gist.github.com/249945
I tried compiling with rake build:debug but the messages and the gdb backtrace are the same.

Also see the following, which shows that it's still a zsuper wrt the other arguments:

In the short- to medium-term, it should be made possible for users to install different versions of any of the bundled libraries. Optionally, perhaps, also leaving the original bundled one around so that it could be used as a fallback.

the defined?(super) idiom can be used to efficiently use modules for plugins, i.e.:

def a_method
  # do stuff
  # ... and then call potential modules that have been included
  super if defined? super
end

rubinius does not implement defined?(super). I guess, though, that it would not be so difficult to at least implement a Kernel#has_super? method that returns true if there is a "super" method.

Kernel#dup uses Object#send underneath, and if #send is undefined (or redefined for another purpose) it explodes. Here is a patch to use #__send__ instead:

I tried to install the FasterCSV gem without 'sudo' today and found that Rubinius tries to install gems to its own path instead of my $HOME directory (happens with MRI, 1.9, JRuby). Here's the verbose output of attempting this install:

Initial build of rubinius with llvm enabled resulted in a hung mspec run. Here is the output:

A dtruss of the process was repeatedly spitting out this message:

Running "bin/mspec ci -B full --background" again resulted in a clean run.

doing a require 'digest/sha1' into Rakefile is solving the issue.

I built rbx 1.0.0rc1 via RVM. During the installation process, it installs the rake gem. However, this errors out with

ERROR:  While executing gem ... (Gem::Exception)
    [BUG] invalid exec_format "rbx", no %s

Running 'rake' in the memcache-client 1.7.7 gem, rbx crashes during the get:ruby:memcache-client benchmark. See example output here:

http://gist.github.com/242346

You will need to have a memcached server running locally to reproduce this.

In order to duplicate,

Step 1, install latest Xcode
Step 2, install brew
Step 2, install llvm from brew
Step 2, install rvm (not sure if this is related, doubt it)
Step 3, git clone rubinus as root, then ./configure --enable-lvm

should take about 30seconds and eventually it spews and you'll find the system is now unstable, /dev/null is missing, and the easiest way to fix said issue is to reboot Snow Leopard.

FYI running SL 10.6.2, with Ruby 1.8.7 p72 (stock ruby)

At first I was running this code:
Object.class_eval { define_method(:z) {|&b| b.call('z')} }
..but this code has the same result: Object.class_eval { lambda {|&b| b.call('b')} }
Outside the class_eval, it throws a SyntaxError.

Kernel#require
- is a private method
- resolves paths relative to the current working directory
- does not expand/resolve qualified files against $LOAD_PATH
- loads a .rb from an absolute path
- collapses consecutive path separators
- loads an unqualified .rb by looking in $LOAD_PATH and returning true
- allows unqualified files to contain path information (just not in the beginning)
- loads a file with ./filename even if . is not in path
- stores a non-extensioned file with its located suffix
- appends a file with no extension with .rb/.<ext> in that order to locate file
- prefers to use .rb over .<ext> if given non-extensioned file and both exist
- will load file.rb when given 'file' if it exists even if file.<ext> is loaded
- will not load file.<ext> when given 'file' if file.rb already loaded
- appends any non-ruby extensioned file with .rb/.<ext> in that order to locate file
- loads extension files
- will load explicit file.<ext> even if file.rb already loaded and vice versa
- stores the loaded file in $LOADED_FEATURES
- will not add a bad load to LOADED_FEATURES
- uses $LOADED_FEATURES to see whether file is already loaded
- will not load a file whose path appears in $LOADED_FEATURES; it will return false
- requires arbitrarily complex files (files with large numbers of AST nodes)
- raises a LoadError if the file can't be found
- raises a LoadError if the file exists but can't be readError: signal SIGSEGV

I've tried running a benchmark in my remix-stash library (binary42/remix-stash). It doesn't seem to make it through the get_set.rb script. To trigger it simply run rbx benchmarks/get_set.rb. I've tested this on OS X 10.6 using 62059fdce.

Methods File::Stat#sticky? and FileTest.sticky? don't exist,
which leads to File.sticky? also not working.

Patch + spec.

mspec before patching:

https://gist.github.com/5a71c62be731876352cc
(the single passing spec is a "check spec for completeness" one)

After patching:

Note: changes platform.rake to add detection for S_ISVTX constant
so a clean rebuild is needed.

Unfortunately currently do not have a backtrace, and it doesn't happen consistently. If I get it to happen again with a backtrace I will post it here.

Ran into this in sinatra/base.rb

That results in:

Captured a Mac OS 'problem report' as well; see the output here:
https://gist.github.com/bde1f71a868baee7c682

Currently I am getting this error every time I run rake or 'rake -t'
It may be that I updated to Mac OS 10.6.2 (from 10.6.1) since my last build. I will start over with a clean one and see if this still occurs.

Simple to reproduce:

This is an easy reproducable segfault, basically the only thing needed to do is install the rdoc with RI enabled.

For a backtrace and some more information, see: https://gist.github.com/7ced204c9a6cfffb1721

Randomly got this running 'rake -t' after a clean build.
Snow Leopard, MBP Core 2 Duo, ARCHFLAGS and CFLAGS are both set to '-arch x86_64'

re-running rake -t a couple of times after the crash resulted in 0 failures.

See the stack trace reported by the Error Reporter here:

B.a

B.new.b

MRI >> :b (super() from the block)
rbx >> :a (super() from the method)

https://gist.github.com/b31d63373fe0608cb8dd

In MRI:

require 'set'
a, b = *Set.new([1,2])

a == 1
b == 2

In Rubinius:

a == #<Set: {1, 2}>
b == nil

When compiling Rubinius for the first time, ./configure has to be run before running rake. Even though the error message tells you as much, it should still be mentioned in the Quick Start.

Patch is here: http://gist.github.com/220856

http://gist.github.com/219811

On running rake, I got the folliwng message:

run ./configure first

The Getting started guide does not mention it.

rb_str_new when given a 0 length should create an empty string, today it creates a string from the entire original cstring passed as the first parameter.

Problem is in string.hpp:92
if(bytes == 0 && str) bytes = strlen(str);

0 is a valid size (according to the MRI API at least)

I have a script that has as first executable line

MYNAME = File.basename($0)

rubinius fails with the following trace:

Which seems to indicate rbx can't find it's runtime dir.

Method#inspect was broken when backed by a Rubinius::AccessVariable:

[].method(:length) #=> NoMethodError: No method 'name' on an instance of Rubinius::AccessVariable.

There are other problems here as well

[].method(:length).call # NoMethodError: No method 'activate' on an instance of Rubinius::AccessVariable.

[].method(:length).arity # NoMethodError: No method 'arity' on an instance of Rubinius::AccessVariable.

At the time, SIGPIPE would cause rbx to exit. There is currently a handler registered that ignores SIGPIPE. Do we need a handler that raises EPIPE?

-fPIC is required to compile objects that need to be included in a shared library. Not having the flag works on x86, but fails on PPC and recent x86_64 linkers.

Right now, a workaround is to add

$CFLAGS += " -fPIC"

to extconf.rb

A segfault results if the VM encounters a (set|push)_local_depth when the scope nesting does not match the depth given.

For example:

class Hash
  def self.allocate
    hash = super()
    Rubinius.privately { hash.setup }
    hash
  end
end

If the compiler does not fix up the local access for hash in hash.setup in Rubinius.privately, the push_local_depth insn will attempt call_frame->scope->parent() and parent is 0x0.

On ubuntu 9.04 using zlib1g-dev library for zlib, the standard spec run has 30 some odd failures do to Zlib.

As discussed on irc: http://gist.github.com/175639

Patch includes change to vm/parser/grammar.y but not grammar.cpp.

This sums it up exactly:
http://redmine.ruby-lang.org/issues/show/1769

Ruby 1.9 acknowledges that this is NOT desired behavior.

http://gist.github.com/152277

The two files in the above gist demonstrate the segfaults that occur executing bin/mspec ci -T-Xjit.enabled with DEV=1 and without DEV=1 set. Note that the segfault without DEV=1 occurs consistantly much sooner then the segfault when running with DEV=1.

This was observed on a 32bit Ubuntu 9.04 box (gcc 4.3.3)

Running a simple ruby script that reads a file, parses through it, and generates a new file (same name) caused the latest commit to produce an assertion failure. I have a tarball of the script along with the sample file that caused it. I'll try to attach them here somehow... otherwise a followup message will contain pointers to gists containing the data.

I'm seeing various failures during gem installation related to RI. They look like the following errors:

./bin/rbx -S gem install rdoc Successfully installed rdoc-2.4.3
1 gem installed
Installing ri documentation for rdoc-2.4.3...
ERROR: While executing gem ... (NoMethodError)

No method 'keys' on an instance of RDoc::RI::MethodDescription.

Installing Rails also shows a similar error:

./bin/rbx -S gem install rails Successfully installed rake-0.8.7
Successfully installed activesupport-2.3.2
Successfully installed activerecord-2.3.2
Successfully installed actionpack-2.3.2
Successfully installed actionmailer-2.3.2

Installing ri documentation for rake-0.8.7...
Installing ri documentation for activesupport-2.3.2...
ERROR: While executing gem ... (NoMethodError)

No method 'keys' on an instance of RDoc::RI::MethodSummary.

As of now, on line 359 in vm/llvm/jit.cpp, ExecutionEngine::create() returns NULL. Then, on line 362, this null pointer is dereferenced, causing a segfault. As I know nothing about LLVM, I can't really say much more than this.

This is the segfault caused when compiling readline on my 64-bit Jaunty, GCC 4.3.3.

Commit 9bdf2fa removed rubinius::InterpreterCallFrame::js, breaking debug code generated when RBX_STACK_DEBUG is set.

running sudo rake install i get:
install -c -m 0644 vm/subtend/ruby.h /usr/local/lib/rubinius/0.11/lib/ext/ruby.h
rake aborted!
No such file or directory - vm/subtend/ruby.h
/work/research/rubinius/Rakefile:130

Install on Ubuntu 9.04 (Jaunty) required installing OpenSSL development libraries to get openssl/ossl_typ.h.

building the actual version (last pull 5min ago, but also some pulls before) fails with:

    vm/parser/grammar.y: In function 'long unsigned int rubinius::parser::scan_hex(const char*, int, int*)':
    vm/parser/grammar.y:5839: error: invalid conversion from 'const char*' to 'char*'
    rake aborted!

Apparently the -O2 flag causes some type of a problem; -O1 etc. work fine, as does rake build:debug (-O0). Using GCC=gcc-4.0 on the same system works without problems.

This appears to be specifically related to the compiler. This is the end of the build output, same error occurs e.g. trying to run bin/mspec.

When I run the Extlib specs from github.com/datamapper/extlib in GDB, I get the following backtrace:

http://gist.github.com/118840

If there is any specific information I need to retrieve, please let me know.

The -X option parser in vm/configuration should warn or raise an error if encountering an option it does not understand rather than just ignoring it.

After a clean build from rake, the normal ci spec run hangs at the above spec. While it is hung, if I do a ps -a | grep rbx, there are 3 entries, one of which is marked . Using gdb to connect to one of the pid's shows a backtrace like so:

Currently this is always reproducable on my Ubuntu 32bit 9.04, gcc 4.3.3 box.

Details here: http://gist.github.com/117762

Only seems to happen when the completion has multiple completion alternatives.

I get a BusError when running the do_postgres specs. The backtrace from gdb is the following:

If there is any more information I can provide, just give me a ping

I wanted to throw specific exceptions from a C extension and found that rb_exc_raise was missing.

(Don't know if Rubinius is open for issues, but anyways)

Tried to use Rubinius (code from today) to run Buildr (a build tool based on Rake for Java). I get this:
An exception has occurred:
