Bug fixes:
14353 Advising subclass method that calls super raises exception when method executed
14356 Regexps for types must cover the whole name, which is inconsistent with method/attribute regexps
14384 Design by Contract "extra" does not return correct value "invar" handling
13410 Fix funky navigation bar on website
14353 was kind of bad, but it's actually a Ruby bug with a good workaround. If you
advised a method that called "super", Ruby would use the wrong method name to lookup the
class in the parent. See the bug description for the details.
For 14356, type regular expressions now match on parts of names; they don't have to match
the whole name. The exception is regular expressions with module separators "::". In this
case, it seems to make more sense for the regular expression to be interpreted as follows:
If the expression is /A::B::C::D/, then for the the outermost types, the expression behaves
as /^.*A/, for the types between two "::", the expressions behave as /^B$/ and /^C$/, and
the trailing expression behaves as /D.*$/.
14384 was an easy mistake to make with "around" advice; you have to remember to return the
result of the "join_point.proceed" call, unless you specifically want to change the returned
value! Here are two ways to do it:
do_something_before(...)
result = join_point.proceed
do_something_after(...)
return result
or
begin
do_something_before(...)
join_point.proceed
ensure
do_something_after(...)
end
The latter approach looks "asymmetrical" and it will behave differently if "proceed" raises!
However, it eliminates the temporary, if you find that desirable.
Enhancements:
13407 Pick a better method name for JoinPoint#type, which hides the Module#type
14385 Pointcut.new should accept a :join_point => jp argument
14386 Aspect.new ..., :pointcut => should accept a join point object
14440 Add good warning message when "proceed" used for non-around advice
For 13407, new attribute methods have been added
Changes:
* JoinPoint#target_type return the type that the join_point matches.
* JoinPoint#target_type= set the type that the join_point matches.
* JoinPoint#target_object return the object that the join_point matches.
* JoinPoint#target_object= set the object that the join_point matches.
*
* e following, older methods are now deprecated and will be removed in the 0.2.0 release (#14053):
* JoinPoint#type
* JoinPoint#type=
* JoinPoint#object
* JoinPoint#object=
