The driver should convert Int64 to Bignum, using e.g. Kernel#Integer:

>>> i64 = System::Int64.new(1000000000000)
=> 1000000000000 (Int64)
>>> Integer(i64)
=> 1000000000000
>>> Integer(i64).class
=> Bignum
>>>

Only problem i've ran into with this method for now has been the usage of 
System::Int64 for Primary keys.

In a join table it was storing the yaml representation of the Int64 object 
instead of the proper Integer value,

as a quick patch I've applied the following but i'm sure there is a better 
safer way;

class System::Int64

 def to_i; self.to_s.to_i; end

end

I went out of my way and decided to have a look at updating the SQlite dll.

It seems the interface has changed since sqlite3-ironruby gem release.

I have downloaded and put the Community.CsharpSqlite.dll in the native folder:
http://code.google.com/p/csharp-sqlite/downloads/list?can=1&q=&colspec=Filename+Summary+Uploaded+ReleaseDate+Size+DownloadCount

Then I have adjusted driver.rb to: http://pastebin.com/diff.php?i=7e522Rvs

Most things seem to just work, and it's blazing fast now, about as fast as Ruby 
1.9.2's sqlite3 performance!

I thought i'd let you know in case experiencing similair issues :-)

slow, reads fast
Hello,

I am since some weeks working with IronRuby.
I do not consider myself a great programmer in neither Ruby or .NET, yet I 
really love Ruby, and in these past few weeks IronRuby and .NET in general has 
really grown on me; very powerful!
So first; my gratitude for this amazing product, thanks to all who make this 
possible!

My project's available @ Github: https://github.com/sickboy/six-updater-gui

My current issue is that SQLite writes seem to take at least 0.7 seconds per 
write.
So if I update 100 records at once in 1 query, it will take ~0.8s.
But also if I update 1 record, it will take ~0.7s..
In comparison, the same actions with mingw Ruby 1.9.2 (from RubyInstaller.org), 
these writes take only about 0.005s

Reads seem to be okay.

Is this a known problem? Is there anything that can be done about this?
Do others see these long delays as well? How about msSQL (/Express)?


Not sure if I should create a seperate mail thread for this;
The second problem i'm having is that when I load a database model with 
ActiveRecord 2.3.8 into a BindingList, and that to a BindingSource, and assign 
it to a DataGridView, everything is fine.
When I use ActiveRecord 3.03, I get "A singleton class has no underlying system 
type". Unless I don't add records to the binding list, before assigning the 
BindingSource as data_source of the DataGridView, and instead, add records to 
the binding list after assigning the data_source.
I am not sure how I should debug this problem.


Lastly I have the feeling (based on timing results in my logs) that processing 
IronRuby scripts is faster when they run through the ir.exe interpreter, than 
when they are executed in an engine from within a c# app.
Could that be because certain optimizations are enabled in ir.exe, or something 
similair?


Thanks for your time!
