• Recognizing Tail-recursive functions with Flex+Bison and convert code to an Iterative form

  - by Viet

  I'm writing a calculator with an ability to accept new function definitions. Being aware of the need of newbies to try recursive functions such as Fibonacci, I would like my calculator to be able to recognize Tail-recursive functions with Flex + Bison and convert code to an Iterative form. I'm using Flex & Bison to do the job. If you have any hints or ideas, I welcome them warmly. Thanks!

• How do I compile irb from source on Ubuntu?

  - by steadfastbuck

  I would like to compile irb from source without any optimizations so I can get more information while stepping through (interpreter) code using gdb. I have successfully compiled ruby 1.9.1 without problems, but I cannot find any documentation regarding irb. I believe that irb is included in the ruby 1.9 source, but have not been able to verify this. Can anyone point me in the right direction?

• Add a Binding Extension via Code

  - by FlySwat

  I'm trying to figure out a way to add a binding extension to an endpoint via code, instead of through configuration files. Ideally I want it to simply be an attribute I place on the service method. So far it seems like the only thing that isn't exposed publicly is the binding extensions.

• Possible to be adequate with respect to decision/condition coverage but not block coverage?

  - by bparker

  Following up on a debate that I was having with a colleague. What is the community's opinion on whether or not a section of code can be adequate with respect to decision coverage (all possible decisions have evaluated to true and false) but not block coverage, and if a section of code can be adequate with respect to condition coverage (each simple condition in a compound conditions has evaluated to true and false) but not block coverage. Thanks.

• How do polymorphic inline caches work with mutable types?

  - by kingkilr

  A polymorphic inline cache works by caching the actual method by the type of the object, in order to avoid the expensive lookup procedures (usually a hashtable lookup). How does one handle the type comparison if the type objects are mutable (i.e. the method might be monkey patched into something different at run time). The one idea I've come up with would be a "class counter" that gets incremented each time a method is adjusted, however this seems like it would be exceptionally expensive in a heavily monkey patched environ since it would kill all the PICs for that class, even if the methods for them weren't altered. I'm sure there must be a good solution to this, as this issue is directly applicable to Javascript and AFAIK all 3 of the big JS VMs have PICs (wow acronym ahoy).

• Why does it matter that in Javascript, scope is function-level, not block-level?

  - by Jian Lin

  In the question http://stackoverflow.com/questions/1451009/javascript-infamous-loop-problem the accepted answer from Christoph's says that JavaScript's scopes are function-level, not block-level What if Javascript's scopes are block-level, then would the Infamous Loop problem still occur? But will there be a different (or easier way) to fix it? Is it as opposed to other languages, where using a { would start a new scope?

• Invoking web service methods from code-behind

  - by Peter Wone

  The application on which I am working has a web service exposing various methods. Most of these methods use WebOperationContext.Current to set headers up to prevent cacheing. This works fine when the service methods are consumed in AJAX via the generated proxy, but when I attempt to do the same thing from code-behind, WebOperationContext.Current is null. Can anyone tell me how to confer appropriate call context on the method invocation?
