927455 - Text::Wrap 2012.0818 incorrectly parses strings when $Text::Wrap::huge = 'wrap'

Status: RESOLVED INVALID

(Bugzilla :: Creating/Changing Bugs, defect)

Description

[Rednuht]

Environment: Windows 2012 server, mysql-5.5.29-winx64, ActivePerl-5.14.3.1404, IIS 8, Bugzilla 4.2.5

Problem:
When submitting a comment only to a certain bug the following error is thrown:

"Bugzilla has suffered an internal error. Please save this page and send it to [e-mail] with details of what you were doing at the time this message appeared. 

URL: https://bz.whatever.com/process_bug.cgi
 
undef error - This shouldn't happen at C:/Perl64/lib/Text/Wrap.pm line 84.  "

The comment is recorded in Bugzilla but Bugzilla doesn't send the email after the above error occurs.

Steps taken to isolate the issue but the issue still persists:

1. Restart of the server ...
2. Run checksetup.pl
3. Set email to none
4. The issue happens when changing anything to the bug not only adding a comment.
5. Deleted the comments from the database from that specific bug but still the issue appears when entering a new comment.
6. Exported the bug in XML and imported it back and the new Bug doesn't show any problems.
7. Exported the database to a test server and the same behavior was observed to the same bug.

Any help is much appreciated.

Best regards, 

Rednuht.

I doubt the error message says "This shouldn't happen" or Perl has a lot of humor.

Without more information, there is nothing we can do for you. Probably someone inserted some invalid character in a bug comment (which is the only one calling Text::Wrap). Also make sure your installation uses UTF8 as encoding.

Restarting the web server or running checksetup.pl again obviously has no effect.

I would tend to consider this bug as a support question. Please visit http://www.bugzilla.org/support for help.

Created an attachment with the error, it seems that Perl really has a lot of humor.

As discussed on IRC, the problem is due to (probably) an invalid string in the See Also field. This makes it a support question, not a bug in Bugzilla.

After editing the file C:/Perl64/lib/Text/Wrap.pm and adding to line 84:

die "This shouldn't happen: $t";

the error message changed pinpointing to the first bug from the see also field:

undef error - This shouldn't happen http://bz.whatever.com/show_bug.cgi?id=xxxxx at C:/Perl64/lib/Text/Wrap.pm line 84. 

where the xxxxx bug is actually the first bug from the see also field

Thank you for your help in pinpointing the cause of this issue !

Best regards,

After some more investigation, it appeared that Text::Wrap 2012.0818 was buggy. Upgrading to a newer version of Text::Wrap fixed the problem.

 Frédéric Buclin actually discovered that this is a bug in Text::Wrap 
https://rt.cpan.org/Public/Bug/Display.html?id=79766

After upgrading : ppm upgrade Text::Wrap

the issue is fixed now.

Awesome support !!!

Should we blacklist that version of Text::Wrap then?

No. It's not part of our requirements, and Text::Wrap is part of the core Perl distribution. You can hardly ban a core module.

This problem has arisen in my installation of Bugzilla.

Although I have full access to the server on which Bugzilla is installed, I'm largely clueless as to upgrading to later versions, updating Text::Wrap etc. I have Bugzilla installed on a Windows server, and my familiarity is with MacOS.

As a relative dummy, will it likely be easier for me to solve this problem by updating Text::Wrap, or upgrading my current Bugzilla 4.2.4 installation to 4.4.1, assuming that either would solve the problem ?

Many thanks
