CLOB handling in ActiveRecord 1.14.2
We recently switched to Rails 1.1.2, which includes the latest version of ActiveRecord. This version seems to have introduced an error with the handling of non-binary large objects. The OCI adapter in 1.13.2 seemed to have treated CLOB and BLOB identically. The new Oracle adapter distinguishes between the two types and gives CLOB a type of :text, where as BLOB are :binary When it comes to

Anyone know what''s up with the activerecord session store when using the oracle adapter in Rails 2.0.2 ? I can set a session variable and can then see it''s actually set using the debugger, but after the request completes the session is empty (the @data member is nil). The session_id is staying the same and the updated_at field is being updated but nothing I put in a session

acts_as_tree and before_save
We all know that acts_as_tree gives us ability to set up data in a tree-like structure and use methods like ''parent'', ''children'' and so on. Something I''m completely stuck on. Observe. class Page < ActiveRecord::Base acts_as_tree def before_save raise self.parent.to_yaml end end Well, you''d think that it should show

not able to find to_yaml definition
I am looking at rails edge source code. I am able to do puts User.find.to_yaml However I am not able to find piece of code where ''def to_yaml'' is. How this to_yaml serialization is working? can fully understand how to_json and to_xml is working but to_yaml beats me.

[PATCH 0/8] RFC: ia64/xen TAKE 2: paravirtualization of hand written assembly code
Hi. I rewrote the patch according to the comments. I adopted generating in-place code because it looks the quickest way. The point Eddie wanted to discuss is how to generate code and its ABI. i.e. in-place generating v.s. direct jump v.s. indirect function call Indirect function call doesn't make sense because ivt.S is compiled multi times. And it is up to pv instances to choose in-place

Mystified by ActiveRecord.serialize
I''m either missing a step, confused or seeing some odd behavior with ActiveRecord''s serialize feature. When I load an ActiveRecord object from the database, my serialized attribute is a YAML::Object, not the original object. My code is based on an example of this capability in the "Agile Web Dev. w/ Rails" book (p. 196). In create.sql: <code> create table
