Got the answer I need from the Programming Ruby 2nd Edition book and thought
I would share it here.
From the "Handling Exceptions" section (p. 361), I got that I should add the
"rescue" block to the end of my site-walking methods, and not the calling
method (i.e. page_set_to_check()). Basically I was using the rescue block
in a way that Ruby didn't pay attention to.
So I made the following changes to my script:
(1) delete the page_set_to_check() method
(2) added the following rescue block to the end of each page set
(site-walking) method:
----
module site_walkabout_methods
...
def walk_Public_Pages
# launch ie
# goto some page
# get page size and download time
# click to another page. yadda, yadda.
# ...
rescue => e
$something_went_wrong = 'Yes'
puts e
ensure
write_status
end
end
----
So the methods themselves are self-correcting and I don't need to try and
capture exceptions with some umbrella method. Cool.
I'm happy. Moving on..
Cheers. Paul C.
