Since it looks like we're going to start discussing changing the EH representation again, I think it would be a very good idea to first review the core requirements we have of the exceptions IR. Mostly, here, I'm taking the major exceptions implementations I have direct knowledge of --- zero-cost DWARF-based libUnwind with the default GCC personalities, builtin_sjlj-based libUnwind with

This is a semantic question. (I''m doing some technical writing about DTrace.) I''ll little confused about how to explain what an "action" is. By any definition, "trace(x);" is an action. However, what about just "i++;"? Looking at the DTrace guide page 76: "Probe actions are described by a list of statements separated by semicolons (;)

Hi, Here''s my problem. I tried to google it, read the release-docs and haven''t found anything similar. My application uses folders to store controllers, as described in the Rails book.

The user enters and the "list" action is called and I populate an instance variable "@news" which contains all the elements I''d like to display using a form. The user then changes something and the "update" action is called. Is

So I''ve recently started playing with the restful routes support in edge rails, converting a few of my controllers to support all the standard operations.. One thing that''s been bothering me, however, is the following: Before using restul routes, I would define an edit method in my controller which would be responsible for both creating new objects as well as editing

Say that there''s a piece of functionality I want to call everytime the controller is invoked, regardless of what action I am calling. Where do I put that, exactly? Can I do that? -- Posted via http://www.ruby-forum.com/.

Rubyists: Consider the following monstrosity, coded using assert_select: assert_select "div#logo_box img[src=/0000/0001/logo.gif][alt=My Company]" Now, behold it rewritten to use assert_xhtml: assert_xhtml do div.logo_box! do img :src => /logo.gif$/, :alt => ''My Company'' end end That sample contains more Ruby; it''s not just

All assumptions aside, "rectest" and "salt" are usernames not databases/schemas according to the pasted config. If they were in fact different databases/schemas, this problem could never have happened. While different database brands may have tricks for ways to handle users and what they perceive as a database/schema, the fact remains that if 2 literally separate databases

i''m still pretty new to rails, and while i''ve been able to hack my way into having it do what i want so far, i''m not happy with the way my code looks. on top of that, i''m sure that what i''m doing prlly isn''t the most efficient either. one of my biggest problems is probably to do with using relationships and forms together. i''ve

I''ve been working with ActionMailer for a few days and finally have a pretty good grasp of it. In the book I''m reading, it shows how to send to multiple users or an array of users. Is there a setting or some configuration I can do to send the email to each person separately, or would I just need to loop through each user and send one email at a time? What is the best way to
