357374 - Can't locate object method "use_for" via package "Bugzilla::Group"

Status: RESOLVED FIXED

(Bugzilla :: Administration, task)

Description

[Max Kanat-Alexander]

Several users have reported that editgroups.cgi does not work for them in 2.22.1, and when they try to load it (just clicking on "Groups"), they get the following error:

undef error - Can't locate object method "use_for" via package
"Bugzilla::Group" at C:/Perl/site/lib/Template/Stash.pm line 870.

I can't reproduce this on landfill.

Comment 1

[Max Kanat-Alexander]

The template line is probably this one:

[% FOREACH group = groups %]
  [% group.use_for = (group.isactive != 0) && (group.isbuggroup) %]
[% END %]

I don't know why the Template-Toolkit is trying to call a subroutine instead of just setting the value, though.

Comment 2

[Frédéric Buclin]

This is not something I can reproduce and none of our Selenium scripts failed when calling editgroups.cgi. Neither on 2.22.1 nor on 2.23.3. WFM.

Comment 3

[Max Kanat-Alexander]

It's possible that it's Windows-specific.

I have multiple different users reporting it, so it sounds like something is wrong.

Here's the checksetup output of one of the users reporting it:

(In reply to comment #1)
> [% FOREACH group = groups %]

> [% END %]

wwang:

if you write

[% SET group.use_for = (group.isactive != 0) && (group.isbuggroup) %]

in template/en/default/admin/groups/list.html.tmpl, does this fix your problem? (i.e. adding "SET" before group.use_for)

Comment 7

[wwang]

I made the change as you suggested at line 128 of list.html.tmpl and it still gives me the same error.

Comment 8

[Frédéric Buclin]

I tried with a 2.23.3 installation on Windows 2000 SP4, Perl 5.8.8 Build 819, MySQL 5.0.26, Apache 2.2.3 and I still cannot reproduce the bug. I know this bug is about 2.22.1, but the code in admin/groups/list.html.tmpl is the same.

Comment 9

[Rudolf Naujack]

I've the same bug on w2k with activestate perl 819

Comment 12

[Frédéric Buclin]

Per comment 11, this bug doesn't seem specific to Windows. Comparing comment 8 and comment 9, the bug doesn't seem related to ActiveState Perl 5.8.8 Build 819 nor Windows 2000. Byron says he cannot reproduce the bug using TT 2.15 despite some others can using this version of TT. So my question is: what's the common config of all these broken systems??? This cannot be a problem related to the web server (either Apache or IIS) nor to the DB (MySQL or PostgreSQL).

Note that comments 3, 5, 9 and 11 all report the problem against TT 2.15. Maybe you need this specific version of TT + some other specific (broken?) module? It would help a lot if one of the users having this problem could downgrade their TT module to 2.14 or lower and tell us if the problem still occurs.

Comment 13

[Frédéric Buclin]

Bingo! I just upgraded TT on my W2k installation from 2.13 to 2.15 and I can now reproduce the bug with exactly the same error message as in comment 0.

Comment 14

[Frédéric Buclin]

I can now reproduce the bug on Linux too if I comment the eval() in the BEGIN block of Template::Stash::XS:

BEGIN {
  require DynaLoader;
  @Template::Stash::XS::ISA = qw( DynaLoader Template::Stash );

  eval {
  #  bootstrap Template::Stash::XS $Template::VERSION; # I commented this line!
  };

Else bootstrap() loads /usr/lib/perl5/vendor_perl/5.8.8/i386-linux/auto/Template/Stash/XS/XS.so instead of /usr/lib/perl5/vendor_perl/5.8.8/i386-linux/Template/Stash.pm.

So my feeling is that there is really something wrong in Stash.pm, but that loading XS.so hides this problem for some unknown reason (maybe because it preloaded its own version of Template::Stash::set()).

Maybe related to http://tt2.org/pipermail/templates/2006-February/008367.html?

See also http://www.template-toolkit.org/download/stable/Changes

I'm not sure I understand correctly, but it seems that missing methods are no longer ignored and falling back to a hash is no longer performed.

Comment 15

[Frédéric Buclin]

If I'm right in my previous comment, we have no other choice than defining methods out of templates and move these definitions in Perl modules themselves.

I will keep bootstrap() commented for a few days on my local installations to see if there are some other places to fix. This means we should now release 2.22.2 asap.

The age of this file is 7/24/2003


Seem to be looking for a different path than the original error:

Modifing the perl module resolved it, but I don't like the fix.
Can anyone point me to why I was referencing that particular path... My env (windows) doesn't set that path.

This is not the right place to get support. It looks like you are having some conflict with your Perl packages.
