Hi all, I would like to propose a mechanism that allows IR modules to co-operatively build a pointer set corresponding to addresses within a given set of globals. The specific use case I have in mind is to provide a mechanism for a C++ program to efficiently verify (at each call site) that a vtable pointer is in the set of valid vtable pointers for the class or its derived classes. One way of

I would start from using module-level metadata. An IR extension might be a good idea once we show that - the proposed indirect call protection mechanism is efficient and useful, and - there are other use cases for the IR extension. --kcc On Wed, Jan 28, 2015 at 2:57 AM, Sean Silva <chisophugis at gmail.com> wrote: > Is there any way to accomplish this that doesn't require

So, bitset would be a property that means : globals with the same name will append on a string of bits in the order in which they appear, and it's the job of the front end to make sure the correct order is followed in every unit, so that linking does the right job in every corner case? Could that be used for efficient global boolean flags, like LLVM's options? Even if you don't need

My original post might have been overlooked by most, but I''ve made a plugin (link below) which allows rendering of objects directly via the render method: <%= render @some_object %> which would actuall render the @some_object object (the object is even able to handle the options hash. Rendering would actually be handeled by the object itself, by leaving it up to the object to

I can not seem to make finders work with aliases. My goal is to map some fugly field names to nice field names and have the finders work with the nice field names. An example. class Users < ActiveRecord::Base alias :password :UserPWD end This doesn''t seem to work because obviously the object doesn''t have a method called UserPWD. What is the best way (short of a view) to

Request for eyeballs. :-) Mongoid uses association proxy objects. It overrides #nil? => false when the association is missing. However since it uses proxy objects, !!assocation is always true. I have created a ticket with a patch that changes the association nil test to call assocation.nil? rather than use implicit coercion of the variable. See:

I have some finders in my models where I write some of the sql myself. I of course want to test these, but am not sure the best way. Should I just let them roll through to the db, and verify they return the correct objects based on the fixtures I load, or should I spec the actual query? I know that DB access is sort of frowned upon, but is this a situation where it is more or less acceptable? My

Hi All! It''s been a while since I had to ask for help, but I''m back! I''ve finished beta testing my big app and started the transition to production. Everything went fine and the production version was working till I was asked to add another model :-( (Almost a year of beta testing and they only come up with it after moving to production :-D ) I successfully

I''m looking through the api for something like find(:all, :distinct => true) so that multiple instances of a row won''t be returned - is this possible? Thanks!

Hi Peter, Please forgive if this is an obvious question, but how reasonable is it for this approach to work when not all translation units are available to be rebuilt with the new information? I'm very interested in what you're proposing here. Jim Sent from my iPhone > On Jan 27, 2015, at 1:07 PM, Peter Collingbourne <peter at pcc.me.uk> wrote: > > Hi all, > > I

Hello everyone, I have another question related to a legacy schema I am working with. Do dynamic finders work with legacy schemas in general? The schema I am working with uses hungarian prefixes for column names. For example fOpen is 0 if a bug is closed and 1 if it is open (type smallint). When I try @bugs = Bug.find_all_by_fOpen(1), I get the following exception: undefined method

I''m having a bit of difficulty when testing my models, I''ve read a few times the testing chapter in Agile web development with rails and at http://manuals.rubyonrails.com/read/chapter/27 but i''m still unsure of what I should be testing. Firstly I''d like to be able to test things like my email validation using lines such as assert User.new(:email =>

Hi, I understand there are total 11 types of key Options for finding a record. The all 11 valid keys for the options hash are :conditions, :include, :order, :select, :group, :joins, :from, :limit, :offset, :readonly, and :lock. We also have Dynamic Finders for the same. e.g. ... find_by etc... I would like to know, how many types of dynamic finders, Active Record provides, to match all those

Hi all, I am not certain this is a 1.8.4 related issue, but I think it might be. I''m trying to use dynamic finders for my Category and Post models, such that a request /blog/categories/general would detect the slug and do a find_by_slug() instead of find(params[:id]). My have_slug?() method works fine, and the dynamic finders *were* working fine until I moved it off my local machine

We have a Page model which acts_as_paranoid. AAP modifies ActiveRecord finders to ignore any records marked as deleted unless the :with_deleted => true option is supplied. We have a UI element which allows users to toggle whether or not to display deleted Pages, their current setting being stored in a session variable, session[:show_deleted]. What we would like is to automagically have

Hi all, I am having a problem with unit tests. Whenever I have a dependency between two models (B depends on A) deleting A should also delete B. This is simple with the dependent parameter in the model file of A. But when I write a test the dependency seems to work, I can''t find the answer with id 1 anymore(Answer.find(1)). But I appearently _do_ find it with
