JRuby 1.6.6 Released

2012-01-30T00:00:00-06:00

The JRuby community is pleased to announce the release of JRuby 1.6.6.

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

The primary goal of the 1.6.x series is to round out our 1.9 support by fixing any reported incompatibilities. Of course, as with any JRuby release, we will continue fixing any found incompatibilities and also improve performance. All users of 1.6.5.1 (and lower) are encouraged to upgrade to 1.6.6.

Because master keeps getting further and further away from our 1.6 branch we have decided to make this our last 1.6 release. We largely fulfilled our goal of having reasonable 1.9 support. Follow up fixes for 1.9 support will only be fixed on master from this point forward. JRuby 1.7.0 will be the next release of JRuby.

Notable Changes:

Updated stdlib to match Ruby 1.8.7p357 and 1.9.2p312
Updated RubyGems to 1.8.15
Multiple 1.9-mode yield/splat bugs fixed (pp, rspec 2.8 working again)
Multiple 1.9-mode encoding bugs fixed
Critical fixes in Random and Fiber
Map Scala operator methods to symbolic names ($plus, etc)

JRuby 1.6.5.1 Released

2011-12-27T00:00:00-06:00

The JRuby community is pleased to announce the release of JRuby 1.6.5.1.

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

JRuby 1.6.5.1 is a special release with a single patch applied to our JRuby 1.6.5 source to correct CERT vulnerability CERT-2011-003. All users are recommended to upgrade to JRuby 1.6.5.1 to get this security fix.

A fuller JRuby 1.6.6 with bug fixes from the last two months will be released mid-January…

Background for the CERT advisory:

(for the impatient: predictable hashing algorithm and open access to a hash from a server can possibly allow Denial of Service (DOS) attacks)

Hashing 101

Hash tables apply a math function (hashing function) to the key of a key-value pair. The result of the hashing function is a location to a hash bucket which stores the key/value pair internally:

a[:heh] = 1
hashing_function(:heh) -> store :heh/1 in hash bucket #3
a[:foo] = 2
hashing_function(:foo) -> store :foo/2 in hash bucket #13
a[:bar] = 3
hashing_function(:bar) -> store :bar/3 in hash bucket #1

Hashes have many buckets and in theory all key/value pairs added to a hash will get spread out evenly across the hashes buckets. In practice, some number of keys will end up hashing into the same hash bucket (known as a hashing collision). As you get more key/value pairs stored to the same hash bucket the time to access those particular key/value pairs will slow down. This is because you need to walk some portion of the entries in the bucket to find the specific one you are looking for (hash structures will often make entries in an individual bucket a simple list structure).

a[:gar] = 4
hashing_function(:gar) -> store gar/4 in hash bucket #3 (same bucket as :heh)

In this example, accessing a[:gar] and a[:heh] may take longer than the other keys because they are sharing a hash bucket.

The Attack

The general application of the attack is for “the bad guys” to figure out a large set of values which will hash to the same hash bucket. Once they create this list they will send all those values to a server. The server will store them in a hash (think parameter list in Rack, for example). The act of storing or accessing any of those values takes longer and longer as the number of entries in a single hash bucket grows. The result will be a Denial Of Service (DOS) attack if enough values get stored.

hashing_function(:hostname) -> hash bucket #3
hashing_function(:aZ1) -> hash bucket #3
hashing_function(:cvg) -> hash bucket #3
hashing_function(:azr) -> hash bucket #3
... # many elided
hashing_function(:1fr) -> hash bucket #3
hashing_function(:yu3) -> hash bucket #3
hashing_function(:hyX) -> hash bucket #3

host = params[:hostname] # Uh oh! need to find this amongst many bucket buddies

The Fix

Adding a little bit of randomization to the hashing algorithm ends up making it much, much more difficult to figure out how to generate this type of attack. JRuby 1.6.5.1 (and all later JRuby releases) all have this additional randomization built into the hashing algorithm. The result should be decent hash bucket distribution that is difficult for attackers to predict. More information

This vulnerability is not exclusively an issue of JRuby. Other Ruby implementations also have a similar issue (also patched today). In fact, Java and PHP also appear to be susceptible to this style of attack. For more information, please see the CERT announcement.

Also, consider that language implementations are really only susceptible to this attack via frameworks which allow an external hacker to store arbitrary and/or unbounded key/values into a hash. Ruby Rack had this vulnerability, but they have fixed things so that the amount of parameters stored is bounded by a size to remove the possibility of a DOS attack. Rack users should upgrade to the latest version.

JRuby 1.6.0 final is out!

JRuby 1.6.0 is the largest release of JRuby to date. This release fixes hundreds of user issues and brings compatibility with Ruby 1.9.2 to a very high level. We have made Windows a primary supported platform by adding it to our continuous integration environment. JRuby 1.6 will provide Windows-based Ruby users with the best experience yet. This release integrates experimental support for C extensions based on Ruby’s C API. And as with all major releases, we have improved stability and performance across the board in response to real-world user input.

Over the next month or two we plan on putting out quicker point releases in anticipation that 1.6.0 will get a new wave of feedback. Give JRuby 1.6.0 a try and let us know how things go.

Major Features:

Ruby 1.9.2 language and API compatibility
- Not implemented Encoding::Converter, ripper
Improved Ruby call performance
Built-in profiler (–profile, –profile.graph)
RSpec no longer bundled
C Extension support (experimental)
RubyGems Maven support (preview)
Improved compatibility and user experience on Windows
jruby-complete.jar now includes 1.9 standard library
Embedding API refinements
Over 2000 commits and 270 issues resolved.

JRuby 1.6.0.RC2 Released

2011-02-09T00:00:00-06:00

The JRuby community is pleased to announce the release of JRuby 1.6.0.RC2.

JRuby 1.6.0.RC2 is the second release candidate of JRuby 1.6.0.

JRuby 1.6.0 is the largest release of JRuby to date. This release fixes hundreds of user issues and brings compatibility with Ruby 1.9.2 to a very high level.

This release integrates experimental support for C extensions based on Ruby’s C API. And as with all major releases, we have improved stability and performance across the board in response to real-world user input.

We encourage Ruby and JRuby users alike to test out 1.6.0.RC2 to help us shake out remaining issues. It would be especially helpful if users would test out 1.9 mode (by passing –1.9 flag) to help us round out our 1.9.2 compatibility before the final 1.6.0 release.

Large number of 1.9 compatibility issues addressed
- Encoding issues (especially involving Regexp)
- Fiddle implementation
- non-ASCII identifiers
irb (1.8.7, 1.9.2) and command prompt added to Windows installer
Compiler handles all 1.9 syntax now
Fixes for new backtrace accuracy, reliability
Removed all GPL or LGPL-only dependencies
Updated to RubyGems 1.5.0
C extension support prebuilt for OS X, Linux (32/64), Windows (32)
83 issues resolved since RC1

Major Features:
