JDBC driver leak

2009-11-09T17:25:11Z

I am investigating memory leak related to hot deployment of Rails application on GlassFish. One of the hanging references is the JDBC driver, in this case: org.sqlite.JDBC. The class loader is org.jruby.util.JRubyClassLoader.

I tried to fix it by trying to do something like this:

for (Enumeration e = DriverManager.getDrivers(); e.hasMoreElements();) {

Driver driver = (Driver) e.nextElement();

if (driver.getClass().getClassLoader() == getClass().getClassLoader()) {

DriverManager.deregisterDriver(driver);

}

This does not work because DriverManager.getDrivers() returns only the drivers loaded by this classloader so org.sqlite3.JDBC is not even reported although in the debugger I can see it very well and its loaded by JRubyClassLoader.

So the right fix will be in Ruby.tearDown() to do what I am trying to do using JRubyClassLoader loaded class.

I have opened a JIRA: http://jira.codehaus.org/browse/JRUBY-4226

Memory leak due to JRuby runtime not unregsitering JDBC drivers

So AFAIK I can't underegister the JDBC drivers loaded by jruby for a given rails application.

So the right fix will be in Ruby.tearDown() to do what I am trying to do using JRubyClassLoader loaded class. So basically, Ruby.tearDown() should deregister/unregister JDBC drivers

Re: Unable to instantiate a Java Class???

I'm not trying to instantiate an Abstract Class or an interface...I think it was probably because the arguments in constructor were bad.

Hi! It's great to see you doing work like this to extend the reach of
JRuby to new databases. While I'd like to accept your work as a token
of thanks, my only concern is maintainability of the code. What I'd
like to suggest going forward is one of two possibilities:

1. File an issue on AR-JDBC's JIRA:
http://kenai.com/jira/browse/ACTIVERECORD_JDBC and garner community
backing for the openedge adapter. If multiple independent people
express their desire for the adapter to become part of AR_JDBC, I'd be
more likely to include it.
2. For AR-JDBC 1.0 we're hoping to have a plugin API of sorts for
adding new database support, so a project like yours could be a
standalone gem that you'd simply install on top of AR-JDBC and need to
do nothing further.

Thoughts?

Re: Raising Native Exceptions

2009-11-09T07:47:59Z

Can you file a bug on your example snippet? I think it is a bug, but
OTOH is an instance of a Java Object rooted at Ruby Object? I would
say it has to be a bug since all objects in Ruby space whether
imported from Java or not must be rooted by Ruby Object (or
BasicObject) in 1.9.

Here is a snippet which may capture what you are trying to do a little
more and it also works:

require 'java'

begin
raise java.lang.Exception.new("Hello")
# raise Exception.new("Hello")
rescue java.lang.Object => e
puts e.to_s
end

Active-Record jdbc adapter for OpenEdge databases

2009-11-09T05:49:13Z

Hey !

We work for 2 monthes on an adaptor for Progress OpenEdge Databases(1).
First release is up, with units tests and moreover tested in "real word" on a big project for one of our customers.
It works really fine for now, and we'd want to include it as part of active-record jdbc adapters pack (under MIT license ?).

We ask for you agreement, and thank you for advicing us about the procedure.

For now the adapter sources are on our github repository : http://github.com/kantena/activerecord-openedge-adapter

Re: how about this one? (is it a bug)

2009-11-09T00:43:20Z

Hi,

The problem was two-fold.

1. Minor JRuby incompatibility. 'sane' gem is doing pretty low-level
tricks with core classes. While investigating this a nice way to
speed-up some very common Array operations has been discovered (from
25% to 200%!), which is all good. :)

2. whichr doesn't detect the Windows pratform properly on JRuby. I
keep seeing this over and over again, so I even wrote a blog entry to
bring attention to this problem:

http://blog.emptyway.com/2009/11/03/proper-way-to-detect-windows-platform-in-ruby/

'whichr' gem needs to be corrected.

Thanks,
--Vladimir

P.S. Thanks for filing the bug in our JIRA:

Hi, James,

You're right about what is actually loaded. Upon further reading, I
see that JRuby won't load these builtin libraries during startup; it
just populates builtinLibraries.

When it comes time to 'require',
org.jruby.runtime.load.LoadService.findLibraryWithoutCWD() looks for
built-in libraries first no matter what. There, only builtinLibraries
is consulted to find an appropriate library.

I don't think so.

I added a puts call to to my copy of src/builtin.generator.rb to
announce when it was loaded. I only see that if I call "require
'generator' (no matter how I arrange my $: values).

If you take test.rb, drop the call to "require 'generator'", and have it
print something and exit, src/builtin.generator.rb does not get loaded.

So It appears to be a load path issue.

From the exception, I guess you created a java.lang.Map type object
and called Ruby method with that object in its argument. Right?

This is a Java integration related problem. I think this seems to be a
bug since Map type object didn't converted to Ruby's Hash. In the
method, getMaxList, the Java's Map type object was there as a "hash."
Because Java's Map and its descendants don't have "each" method, you
got the error. Would you file this?

Re: Package support?

2009-11-07T06:43:58Z

Ok, I see that there is rudimentary package support based on the
relative dir in which the file lives. Is that what "we" want? One
thing that's always bugged me about Java files is that they have to be
in the dir structure; but on the other hand, we can't make it *not*
require .class files be in that structure.

Perhaps what actually annoyed me was that you had to put it in the
appropriate path *and* have a "package" declaration in the file?

Package support?

2009-11-07T05:51:06Z

I'm adding package support now, but if you (Ryan) already added it,
let me know. It should be pretty basic, at any rate; an attr_accessor
:package on Script and a PackageNode + macro to create it.

Exciting example:

package org.jruby

Raising Native Exceptions

2009-11-07T03:43:20Z

Hello,

I am having an issue with raising java exceptions from ruby

Googling around I found this http://jira.codehaus.org/browse/JRUBY-1615 which would suggest the issue was solved

I am running jruby right out of git (branch jruby-1_4)

Boils down to this:

require 'java'

begin

raise java.lang.Exception.new("Hello")

# raise Exception.new("Hello")

rescue Object => e

puts e.to_s

end

Thanks for any pointers :)

Re: [jira] Created: (JRUBY-4218) jruby loads src/builtin/generator.rb ahead of any other file named generator

2009-11-06T19:36:26Z

I haven't read too much into the issue, so correct me if I'm wrong.

As I understand it, by the time org.jruby.Ruby.parseFile() is called
on test.rb, an org.jruby.Ruby.init() has already been called and
builtins has already been loaded. By the same token, "prelude",
"java", etc., are also susceptible to this startup logic.

jruby 1.4 CLI vs. embedded syntax difference?

2009-11-06T19:07:10Z

I have a JRuby script that works fine through the JRuby command line. However when I execute the same script in an embedded environment, Tomcat/bsf/jruby, I get undefined method errors. Any pointers as to why the script does not work in the embedded environment?

Thanks,
Ed

code below works with JRuby CLI but not in embedded JRuby!!!
MyHash = {"1" => "One", "2" => "Two", "3" => "Three", "4" => "Four"}
def getMaxList(hash,num)
(num < hash.size) ? hash.values[0..num-1] : hash.values
end
puts getMaxList(MyHash,2).inspect

need to use the alternate form below instead
def getMaxList(hash,num)
result = []
for i in 0..num-1
result << hash[i.to_s]
end
result
end

The error I get with the first form of the code is

<script>:6:in `getMaxList': undefined method `[]' for #<#<Class:01x12e5c94>:0xbffc3a> (NoMethodError)
from <script>:4:in `each'

Exceptions raised NOT from MultipleScriptsRunnerTest are normal. I'm
testing whether the exceptions are raised as I expected or not. But,
exceptions from MultipleScriptsRunnerTest show something wrong are
happening there. In that test, I'm trying to test all scripts under
the test directory. Some of exceptions are perhaps raised because
usages are wrong. Some of them are probably bugs of embedding API or
JRuby only when scripts are executed from embedding API.

I should fix bugs and usages, but currently, I run
MultipleScriptsRunnerTest to know things are not going worse. So, I
neglect all exceptions so that test can go through as many test as
possible. This is why results are OK although exceptions are raised.

BTW, thank you for testing embedding. Your report was helpful since I
don't have windows at all.

Hi Yoko,

While we're at it, how do you launch you test runs for the embedded stuff?
'ant run-junit-embed' or something else?
When running 'ant run-junit-embed', I see occasional stacktraces
during the runs,
but the end result is all OK. Is that how it is supposed to be?

With NailGun JRuby crashes if I started it from console ("cmd") or from

The problem comes from _execute in lib/jdbc_adapters/jdbc_mssql.rb:
def _execute(sql, name = nil)
# [...]
elsif sql.lstrip =~ /^\(?\s*(select|show)/i
repair_special_columns(sql)
@connection.execute_query(sql)
# [...]
end

The CREATE VIEW statement above is recognized as a query because the SELECT keyword appears at the beginning of the second line.

I don't know what the right way to do the recognition is. Maybe DDL statements should always be executed using execute_update?

A workaround for the problem is to move AS from the end of the first line to the start of the second.

File.dirname(__FILE__) doesn't return correct value when a script is loaded from classpath
------------------------------------------------------------------------------------------

Key: JRUBY-4220

Project: JRuby
Issue Type: Bug

When a script is loaded from classpath, File.dirname(__FILE__) returns the base directory. Because of this behavior, test_dir.rb test_file.rb test_io.rb, and test_load_class_before_rb.rb fail. For example, test_io.rb outputs:
{noformat}
[junit] [test_io.rb]
[junit] Loaded suite -

All of those test scripts work well without errors when those are read from absolute path.

Re: JRuby startup very slow on Win7

2009-11-06T10:34:11Z

Cheers for that, Vladimir.

Mate, did you set that RUBYOPT explicitly or was it set by default by
Windows installer?
IMHO, if it causes unexpected delays, should we have it off by
default? Or, have some more direct way to turn it off? For example,
--fast option or a new startup script 'jruby-lite' which would
optimise for one liners and simple scripts.

I guess the other idea for better startup performance: NailGun
(http://kenai.com/projects/jruby/pages/JRubyWithNailgun)
Have only checked with 1.3, but most probably works with 1.4 too:
$jruby --ng-server
Then
$jruby --ng
should be lightning fast.

Also, -that default- JRUBY_HOME setting- caused me some grief on
Windows, when running on Eclipse OSGI (an extra ~15sec delay, fixed by
explicitly setting it).

Good luck,
Gergo

That's a huge win. Awesome tip.

Re: auto test for maven?

There's also the watchr gem. A number of watcher-like gems ... too
many, at least from the perspective of trying to build momentum.

I've been thinking about the same issues re: integration with the
build tools. autotest was kind of a revelation when it came to ease of
testing. But that's just the beginning. What about building HTML from
Haml or CSS from Sass (just a couple of my itches). Or compiling .o's
or .class's. Basically, everything our build tools do, whether they're
maven, or ant, or rake, or make. Why shouldn't those be more event
driven? Coming from autotest, the batch mode feels archaic and annoying.

I suppose the IDEs have mitigated some of these issues, for
environments/users where they're used. But lots of non-IDE things
naturally fit this, too.

But, of course, those build tools aren't structured like that. I find
it a very interesting idea.

In my own experiments, when you do start down this path, things get a
little tricky, quickly, with regard to dependences. Even autotest
doesn't do a particularly good job at this. The problem isn't
implementing dependences, but discovering them. gcc was great with, -M
was it? And I had a whole environment that used jikes just for -M. But
it seems like the cases where dependences are detected and
externalized are the very rare exception. Hierarchical/multiple-pass
makes are equally ubiquitous and evil.

Ah, well, enough of my soap-box. Sorry.

Dear Vladimir!

Thanks, I deleted this value and it's startup is 1.8 sec now.
I didn't checked anything, just installed it and I did would like to try
(and learn) Ruby, but I became terrified. (Sorry my english)

Thank you for your help again!

Best Wishes,
Máté (from Hungary)

Thank you. You're right. After I did "ant clean," all tests passed.

Re: JRuby startup very slow on Win7

Hi Máté,

Your results are very atypical. I also run JRuby every day on Windows
7, and JRuby's startup is around 0.5 sec for me, which is not that bad
for JVM-based language.

Please double check that you don't have %RUBYOPT% set, and you don't
load rubygems by default.

Your fib benchmark shows pretty good numbers for JRuby, compared to MRI. :)

Thanks,
--Vladimir
