161446 - undef error in globals.pl after updgrade to 2.16

Status: RESOLVED WORKSFORME

(Bugzilla :: Bugzilla-General, defect, P2)

Description

[Christoph Pohl]

After upgrading 2.16rc2 to 2.16 using 
'cvs update -rBugzilla-Stable -dP' and './checksetup.pl', I got the following
error message when opening index.cgi:

"Bugzilla has suffered an internal error. Please save this page and send it to
admin@server with details of what you were doing at the time this message appeared.

URL: http://server/bugzilla/index.cgi
undef error - Can't use string ("") as a HASH ref while "strict refs" in use at
globals.pl line 1486. "

This is critical, because it's a complete show-stopper for bugzilla.

Reverting back to 2.16rc2 and doing ./checksetup.pl again still worked fortunately.

That error message is odd..

The tag is Bugzilla_Stable, not Bugzilla-Stable (aka BUGZILLA-2_16) I think that
thats just a typo, though.

Can you try to work out who is calling PerformSubsts with a strange argument
(and what that argument is)

Comment 2

[Christoph Pohl]

You're right about that typo, Bradley.

I'll give it another try but that will take a while since it's a productive
system and I'll have to find a backup machine for testing...

Just an idea: Could it be that I tested the upgrade using the same browser
session from which I was previously logged into the pre-upgrade version of bugzilla?

Comment 3

[Christoph Pohl]

It's exactly as I suspected: My Browser still had a session with the old
Bugzilla 2.16rc2 and the new 2.16 got confused when my browser tried to use the
old (invalid) credentials. 

So, it's not really a bug, but some clarifying remarks about that issue in the
upgrade guide http://www.bugzilla.org/download.html would be greatly appreciated!

[Bradley Baetz (:bbaetz)]

Hmm. That shouldn't make a difference, though - the old session should even
still be valid from rc2.

Can you track down why this is happening?

Not any more. It's working now =8)

Maybe I find the time to setup another bugzilla 2.16rc2 from CVS and update it
to 2.16 in the same fashion. Meanwhile, I don't have the slightest clue about
what's causing the error...

[Christoph Pohl]

Didn't have the time to set up a test system for replaying these problems yet.
But other users of my bugzilla installation encountered the same 'undef error'
even after the clean upgrade. A simple relogin helped them, though. Maybe
something wrong with the cookies?

Comment 7

[Bradley Baetz (:bbaetz)]

Can you find a user who hasn't experienced this yet, and then find out what
value is being substituted when it dies?

Comment 8

[Christoph Pohl]

Update: the problem seems to relate to my modified
template/en/custom/index.html.tmpl and it occures only for logged in users.
Header and footer are always displayed correctly. I just have to find out what's
different in my template compared to the default version...

over 2 weeks since request for update, no response from reporter.  Last comment
from reported was 6 months ago.  Seems no one else has reproduced it...
