Errors thrown when viewing some instance pages in application

(I apologize in advance that I am still running 1.1.9. I'm in the process of updating, but it's an active wiki and I don't want to mess it up...)

I have a Library application - each book has a page. The information for the books is almost entirely stored in the associated form data. Everything except for review comments is stored in the meta data.

When I created the application, there were no errors. However, I noticed today that some (but not all) book pages have started throwing an error: 

Foswiki detected an internal error - please check your Foswiki logs and webserver logs for more information.

Insecure dependency in require while running with -T switch

e.g.

When I checked the Apache error log, the Insecure dependency... was just the tip of the error iceberg:

Additional information
  • None of the above errors are logged for working pages.
  • No errors are thrown when I view a page with raw=debug.
  • No errors are thrown when I edit a page.
  • The Insecure dependency in require... comes from Table Plugin's Core.pm module (but there are no tables in the page data).

Suggestions (beyond "Try 2.0.1" wink welcome.

It dies in the preRendering handler of TablePlugin. You might be best to just turn off Taint checking. (Remove the -T flag from the bin scripts shebang line.) We've disabled taint checking by default in 2.0 because of the issues with locales and supporting international character sets.

-- GeorgeClark - 15 Sep 2015

I'll try that. I'm wondering why only some pages have this issue (and none of the pages use Table plugin).

I tracked down the offending code to 
%INCLUDE{"http://books.google.com/books?id=hiQ19mUyLj8C" pattern="^.*meta name=\"description\" content=\"(.*?)\"\/>.*" warn="off" raw="on"}%

When I remove this line, everything is OK. I'm guessing that something has changed at the Google URL and Perl's -T no longer trusts it.

OK... more testing and now I've seen this:

Screen Shot 2015-09-15 at 20.55.18.png

That explains why, even after removing -T I wasn't getting the expected results.

I've installed the necessary SSL Perl modules and now get 

Failed to include URL https://books.google.com/books?id=hiQ19mUyLj8C Can't connect to books.google.com:443 (Crypt-SSLeay can't verify hostnames)

So, no crashing pages but no desired INCLUDEd text either.

Is there something more necessary to make INCLUDE happy about https?

-- VickiBrown - 16 Sep 2015

I found it.

Add: 
SetEnv PERL_LWP_SSL_VERIFY_HOSTNAME 0
to the Apache config
