[ANN] JRuby 1.1.2 Released

Thomas_E_Enebo · May 28, 2008, 5:03am

The JRuby community is pleased to announce the release of JRuby 1.1.2!

Homepage: http://www.jruby.org/
Download: http://dist.codehaus.org/jruby/

JRuby 1.1.2 is the second point release of JRuby 1.1. The fixes in this
release are primarily obvious compatibility problems and performance
enhancements. Our goal is to put out point releases more frequently for
the next several months (about 3-4 weeks a release). We want a more
rapid release cycle to better address issues brought up by users of
JRuby.

Highlights:

Startup time drastically reduced
YAML symbol parsing >100x faster
Performance, threading, and stack depth improvements for method calls
Fixed several nested backref problems
Fixed bad data race (JRUBY-2483)
Gazillions of bigdecimal issues fixed (all?)

Firstly, congratulations all on JRuby 1.1.2 - it fixed my BigDecimal
problem and seems faster too!

However, it also seems to have introduced a new problem

I am accessing MS SQL Server via the Microsoft sqljdbc.jar which
attempts to load a DLL, sqljdbc_auth.dll, to handle Windows Integrated
Authentication.

Under JRuby 1.1.1, this works fine.
Under JRuby 1.1.2, I get the following error:

28/05/2008 15:50:04 com.microsoft.sqlserver.jdbc.AuthenticationJNI

WARNING: Failed to load the sqljdbc_auth.dll

A little searching showed that this typically means the JVM cant
located the DLL. However, the DLL is in my PATH [jruby\bin], and for
good measure I put a copy into \Windows\System32. No go.

I took compared the jruby.bat and _jrubyvars.bat between 1.1.1 and 1.1.2
and while there are changes between the two versions, nothing stands
out.

I tried setting -Djava.library.path="%PATH" as per one bulletin, but
this didn’t help.

As a workaround, I have switched from Windows Integrated Authentication
to user + password authentication and my app works fine. However, if JNI
is broken, someone else might find this to be showstopper.

Kindly,

Neville

Would you mind putting your description in a bug report so we don’t
lose track of it? Perhaps we can figure out a way to narrow down to
the offending revision that caused the regression.

WARNING: Failed to load the sqljdbc_auth.dll

We were getting that error with jruby 1.1rc1, though it appears to be
fixed in 1.1rc2, 1.1, and (as you said) 1.1.1. I haven’t tried our app
with 1.1.2. In our case, it was due to requiring sqljdbc.jar once in a
parent process and again in a “process” started by rake (e.g. “jruby
script/console” worked, but “jruby -S rake test:units” produced the
error). I assume the problem was something like the jar and its classes
got loaded twice in different classloaders, but the same OS process, and
each sqljdbc jar tried to load the DLL, but the OS returned an error the
second time it tried to load/initialize.

We fixed it by putting sqljdbc.jar in the CLASSPATH instead of doing a
require ‘sqljdbc’. It looks like ‘jruby -J-Djruby.launch.inproc=false -S
rake test:units’ fixes the problem, too.

Ahh yes, multiple loads of a JNI-related library in a single JVM. That
makes sense. Yes, the two workarounds you mention are definitely the two
I’d recommend. Can you add them somewhere on the wiki, perhaps on any
SQL Server page that might exists? This is good information.

We fixed it by putting sqljdbc.jar in the CLASSPATH instead of doing a
require ‘sqljdbc’.

Hmmm, I had placed the sqljdbc.jar in %JRUBY_HOME%\lib - is that the
wrong approach to provide JARs to JRuby?

I note that the _jrubyvars.bat constructs the -cp via looking at all the
jars in %JRUBY%\lib, so maybe that’s why JRuby is loading the
sqljdbc.jar several times on my system?

I’ve tried moving the sqljdbc.jar into a c:\java\shared\ folder, and
setting CLASSPATH=c:\java\shared\sqljdbc.jar but this is giving me a
java.lang.ClassNotFoundException:
com/microsoft/sqlserver/jdbc/SQLServerDriver - am I missing something
here with setting the CLASSPATH?

Finally, I tried adding require ‘C:\java\shared\sqljdbc.jar’ to my
sqlserver_adapter.rb but still got java.lang.ClassNotFoundException.

Clearing I’m missing something [or mistyping something].

Any pointers to setting a CLASSPATH for JRuby under Windows would be
appreciated [I’ve looked at the wiki],

Kind Regards,

Neville

That should have worked just fine.

I’ve tried moving the sqljdbc.jar into a c:\java\shared\ folder, and

java.lang.ClassNotFoundException:
com/microsoft/sqlserver/jdbc/SQLServerDriver - am I missing something
here with setting the CLASSPATH?

I just tried moving sqljdbc.jar around, and was able to get a similar
error, and then I got it to go away, too:

c:\Dev\myapp>jruby -v
ruby 1.8.6 (2008-04-22 rev 6555) [x86-jruby1.1.1]

c:\Dev\myapp>set CLASSPATH
Environment variable CLASSPATH not defined

c:\Dev\myapp>jruby -S rake db:version
(in c:/Dev/myapp)
rake aborted!
The driver encountered an error: cannot load Java class
com.microsoft.sqlserver.jdbc.SQLServerDriver

(See full trace by running task with --trace)

c:\Dev\myapp>set CLASSPATH=c:\jars\sqljdbc.jar

c:\Dev\myapp>jruby -S rake db:version
(in c:/Dev/myapp)
Current version: 159

Finally, I tried adding require ‘C:\java\shared\sqljdbc.jar’ to my
sqlserver_adapter.rb but still got java.lang.ClassNotFoundException.

In the require, try using / instead of .

c:\Dev\myapp>set CLASSPATH=

c:\Dev\myapp>grep sqljdbc config\environment.rb

require ‘c:/jars/sqljdbc.jar’

c:\Dev\myapp>jruby -S rake db:version
(in c:/Dev\myapp)
Current version: 159

Also, jruby will add the .jar for you if you use require to load it:

c:\Dev\myapp>grep sqljdbc config\environment.rb

require ‘…/…/Test/rebates/lib/jars/sqljdbc’

c:\Dev\myapp>jruby -S rake db:version
(in c:/Projects/RDC07015/SCM/Branches/Dev/rebates)
Current version: 159

This all works for me in 1.1.2…

c:\Dev\myapp>…\jruby-1.1.2\bin\jruby -v
ruby 1.8.6 (2008-05-28 rev 6586) [x86-jruby1.1.2]

c:\Dev\myapp>…\jruby-1.1.2\bin\jruby -S rake db:version
(in c:/Dev\myapp)
Current version: 159

Clearing I’m missing something [or mistyping something].

Any pointers to setting a CLASSPATH for JRuby under Windows would be
appreciated [I’ve looked at the wiki],

The approaches I’ve used are:

At the command prompt, or in a batch file, “set
CLASSPATH=c:\jar1.jar;c:\jar2.jar;c:\etc.jar”
Add the jar to jruby’s lib.
Create lib/jars in my application and change
jruby-x.y.z\bin_jrubyvars.bat to add them to the classpath
for %%i in (".\lib\jars*.jar") do @call :setcp %%i
This option works well for our project because warbler bundles up
everything in lib, so this way we get the jars in dev and in production
just by putting them in that directory.
Use “require ‘sqljdbc’”. Note that with sqljdbc in a rails app,
you’ll probably have to add the require line to config\environment.rb.
It must be loaded before AR tries to connect, and some things (like
observers) cause AR to try to connect during initialization.

Another thing I noticed while trying to cause sqljdbc problems this
morning is that sqljdbc behaves the same in 1.1RC1 when [a]
sqljdbc_auth.dll is in the PATH and a second jruby runtime in the same
JVM loads the jar or [b] when sqljdbc_auth.dll is not in the PATH. It
looks like >=1.1RC2 don’t have problems with [a].

Matt

Thanks for your update Matt,

I had given up making JRuby 1.1.2 work with sqljdbc via integrated
authentication, but this post has inspired me to try again following
your lead of editing the scripts.

I suspected the changed scripts from day 1, particularly after Charles
said “Ahh yes, multiple loads of a JNI-related library in a single JVM.
That makes sense.”, but I wasn’t able to determine where the multiple
loading [ie classloaders] was being initiated.

I’m guessing that the -Xbootclasspath/a must initiate an additional
classloader. Perhaps Charles can chime in?

Anyway, it looks like the problem is related to the way jruby’s
scripts
pass the classpath to the JVM… in 1.1.1, they’re all passed via -cp.
In 1.1.2, they’re passed using -Xbootclasspath/a. I tweaked our copy
of
the scripts to pass everything via -cp and nothing via
-Xbootclasspath/a, and I was able to get sqljdbc to connect with
integrated auth (if I put sqljdbc in the CLASSPATH or CP vars). I’m
still not able to get it to work with require.

Apparently I was wrong… when we tried to replace jruby 1.1.1 with
jruby 1.1.2, we started having the integrated auth problem you
described. I’m not sure why it worked a couple weeks ago and not
today…

Have you confirmed that’s the error you’re getting? Ideally I would only
see the SQLite native stuff getting loaded once, regardless of
bootclasspath or not.

Have you confirmed that’s the error you’re getting? Ideally I would only
see the SQLite native stuff getting loaded once, regardless of
bootclasspath or not.

I played with it some more today. I was starting to get frustrated
because I couldn’t reproduce the JNI problem, but instead got lots of
ClassNotFoundExceptions. Eventually, though I figured out that, in
short,
(1) java -Xbootclasspath/a:jruby.jar;sqljdbc.jar …
doesn’t work with integrated auth (which uses JNI) and
(2) java -Xbootclasspath/a:jruby.jar -classpath sqljdbc.jar …
does work. Dropping sqljdbc.jar (the MS SQL Server JDBC driver) into
JRuby’s lib dir adds it to the bootclasspath, whereas adding it to the
CLASSPATH env var makes it get passed to the JVM via the -classpath
switch. Loading it with “require” seems to work, too. So sqljdbc.jar
should not be placed in jruby’s lib directory.

The ClassNotFoundException seems to happen more often with jruby 1.1.2
than with jruby 1.1.1. For example, if I add sqljdbc.jar to the
CLASSPATH env var and run jruby, the following succeeds in 1.1.1 and
fails with cnfe in 1.1.2:
(3) java.lang.Class.forName
‘com.microsoft.sqlserver.jdbc.SQLServerDriver’

The following succeeds in both versions:
(4) com.microsoft.sqlserver.jdbc.SQLServerDriver
or
(5) eval(‘com.microsoft.sqlserver.jdbc.SQLServerDriver’)
or
(6) include_class ‘com.microsoft.sqlserver.jdbc.SQLServerDriver’

(6) is what AR-jdbc uses, IIRC.

I updated the wiki.

Ah, great investigation!

I was worried that someone might suggest that we revert back to
loading jruby.jar
from the classpath, not the boot classpath, thus increasing the
startup time considerably.
And having used to the new/faster startup, that would be really
unfortunate.

Thanks,

We should modify the startup to only load the jruby jar on bootstrap
classpath and everything else in lib and CLASSPATH as normal
classpath. I think that will probably help since most libraries are
not meant to be loaded via bootstrap cp.
