I haven't been able to upload my diff to ReviewBoard because I generated it
with git and I think RB wants something svn-specific. Is there some way I can
get git to generate something acceptable?

You can upload git-generated diff to RB. You should specify pig-git as
repository instead of pig. Please upload your patch to RB.
> Register Statements and Param Substitution in Macros

> There are some gaps in the functionality of macros that I've made a patch to
> address. The goal is to provide everything you'd need to make reusable
> algorithms libraries.
> 1. You can't register udfs inside a macro
> 2. Paramater substitutions aren't done inside macros
> 3. Resources (including macros) should not be redundantly acquired if they
> are already present.
> Rohini's patch https://issues.apache.org/jira/browse/PIG-3204 should address
> problem 3 where Pig reparses everything every time it reads a line, but there
> still would be a problem if two separate files import the same macro / udf
> file.
> To get this working, I moved methods for registering jars/udfs and param
> substitution from PigServer to PigContext so they can be accessed in
> QueryParserDriver which processes macros (QPD was already passed a PigContext
> reference). Is that ok?
