[Bug 1755189] Re: squid3 helper basic_pop3_auth crashes

2021-11-24 Thread Robie Basak
Thank you for working on this!

I agree this is a trivial fix that is unlikely to impact anything
outside of the feature that is already broken.

However, I think it's fair to say that this is fixing a feature that is
in a really obscure corner of use cases. Is there even a single user who
will benefit from this SRU today? If yes, then I'm happy to accept this
upload. But if no then I'm reluctant. Every SRU comes at a cost. There
is some regression risk in the act of rebuilding itself. But there is
also cost in that it is frustrating for users to receive a deluge of
updates every week - in download size and time, in local risk and
downtime during service restarts, and so on.

> [Where problems could occur]

> Since the authentication is now able to continue without crashing,
problems could occour further down in the script. This could include
modifications to the POP3 server used for authentication.

This was also my thought on reading your Test Plan. I appreciate you
identifying this limitation!

Due to the cost to users, if we are going to fix this obscure use case,
I would like at a minimum to confirm that we are actually fixing this
feature all the way through such that the feature actually works. I want
to avoid fixing this now, forcing unaffected users to update, and later
finding that the actual feature doesn't fully work and forcing them to
update again to fix that again.

Conclusions:

1) Please figure out a Test Plan that fully tests the feature, rather
than just getting past this single failure. This requirement might mean
that it's not worth the work effort in continuing until we have at least
one user confirming they would benefit from landing this fix. In that
case I think it would be fine to wait until that happens.

2) I'm going to mark this bug block-proposed-bionic so that it doesn't
land until/unless at least one real user is confirmed still affected, or
if there's a case made for a practical chance that a user will be
affected in the future (seems unlikely on Bionic with Jammy just round
the corner now). SRU verification can continue as normal, and after that
if there's a security or other update necessary then the fix can be
bundled with that so as not to cause any additional unaffected user
impact.

[Bug 1755189] Re: squid3 helper basic_pop3_auth crashes

2021-11-22 Thread Lena Voytek
** Description changed:

+ [Impact]
+ 
+ The basic_pop3_auth command immediately fails when run in Bionic.
+ 
+ Backporting this fix will allow users to authenticate user credentials
+ against a POP3 server as intended.
+ 
+ This is fixed by patching in an upstream commit that properly declares
+ variables in the authentication script.
+ 
+ [Test Plan]
+ 
+ # lxc launch images:ubuntu/bionic test
+ # lxc exec test bash
+ 
+ # apt update && apt dist-upgrade
+ # apt install -y squid3
+ 
+ # /usr/lib/squid/basic_pop3_auth
+ 
+ Global symbol "$server" requires explicit package name (did you forget to 
declare "my $server"?) at /usr/lib/squid/basic_pop3_auth line 92.
+ Global symbol "$pop" requires explicit package name (did you forget to 
declare "my $pop"?) at /usr/lib/squid/basic_pop3_auth line 99.
+ Global symbol "$server" requires explicit package name (did you forget to 
declare "my $server"?) at /usr/lib/squid/basic_pop3_auth line 99.
+ Global symbol "$pop" requires explicit package name (did you forget to 
declare "my $pop"?) at /usr/lib/squid/basic_pop3_auth line 100.
+ Global symbol "$pop" requires explicit package name (did you forget to 
declare "my $pop"?) at /usr/lib/squid/basic_pop3_auth line 106.
+ Global symbol "$pop" requires explicit package name (did you forget to 
declare "my $pop"?) at /usr/lib/squid/basic_pop3_auth line 111.
+ Global symbol "$pop" requires explicit package name (did you forget to 
declare "my $pop"?) at /usr/lib/squid/basic_pop3_auth line 112.
+ Execution of /usr/lib/squid/basic_pop3_auth aborted due to compilation errors.
+ 
+ [Where problems could occur]
+ 
+ Since the authentication is now able to continue without crashing,
+ problems could occour further down in the script. This could include
+ modifications to the POP3 server used for authentication.
+ 
+ The behavior should now match that of the other currently supported
+ distributions, and the script is external to the rest of squid3, but up
+ until now this script has not successfully run on Bionic.
+ 
+ [Original Description]
+ 
  Ubuntu Xenial
  perl is v5.22.1
  squid3 version 3.5.12-1ubuntu7.5
  Running basic_pop3_auth pop3_server gives :
  
  Global symbol "$server" requires explicit package name (did you forget to 
declare "my $server"?) at ./basic_pop3_auth line 92.
  Global symbol "$pop" requires explicit package name (did you forget to 
declare "my $pop"?) at ./basic_pop3_auth line 99.
  Global symbol "$server" requires explicit package name (did you forget to 
declare "my $server"?) at ./basic_pop3_auth line 99.
  Global symbol "$pop" requires explicit package name (did you forget to 
declare "my $pop"?) at ./basic_pop3_auth line 100.
  Global symbol "$pop" requires explicit package name (did you forget to 
declare "my $pop"?) at ./basic_pop3_auth line 106.
  Global symbol "$pop" requires explicit package name (did you forget to 
declare "my $pop"?) at ./basic_pop3_auth line 111.
  Global symbol "$pop" requires explicit package name (did you forget to 
declare "my $pop"?) at ./basic_pop3_auth line 112.
  ./basic_pop3_auth had compilation errors.
  
  adding my before $server on line 92 and before $pop on line 99 solves
  the problem.

Cosmic has reached EOL in 2019; Xenial has entered ESM last year.
Therefore, making this bug as Won't Fix for both.

Hm, this is complicated to manage in lp. Cosmic has the package "squid"
(not squid3), and is affected. Disco has "squid" but is NOT affected.

Xenial and Bionic have "squid3", and are affected.

Confirmed, and it's still a problem in git upstream even. Looks like not
many people use this script, or maybe a more recent perl is enforcing
something that it wasn't before.
