Bug#585796: local-debbugs: Cannot search

[Jonathan Nieder <jrnieder@gmail.com>]

Package: debbugs-local
Version: 2.4.2~exp0

Following the advice in http://bugs.debian.org/542249, I _almost_
have debbugs-local working.  I admit I am not very familiar with
how debbugs is supposed to work.

1. libnet-server-perl is needed for the Net::Server::Fork module used
by ‘local-debbugs --daemon’:

 # cupt install nginx debbugs-local libhttp-server-simple-perl libnet-server-perl
 # echo '1;' >/etc/debbugs/config
 $ local-debbugs --mirror

2. $ENV is set here locally, which led to taint errors.

 $ local-debbugs --daemon --no-detach &
 $ local-debbugs --search severity:serious
 [...]
 Insecure $ENV{ENV} while running with -T switch at /usr/share/perl5/Debbugs/Config.pm line 292.
 Compilation failed in require at /var/lib/debbugs/www/cgi/pkgreport.cgi line 18.
 BEGIN failed--compilation aborted at /var/lib/debbugs/www/cgi/pkgreport.cgi line 18.

Adding “delete @ENV{'IFS', 'CDPATH', 'ENV', 'BASH_ENV'};” in
Debbugs/Config.pm right above “my $temp_hostname = qx(hostname --fqdn);”
fixes this.  It would be possible to restore $ENV{ENV} afterwards, but
I don’t see much point.

3. Searches seem to require a /etc/debbugs/indices/sources file:

 $ local-debbugs --search severity:serious
 Unable to open /etc/debbugs/indices/sources for reading: No such file or directory at /usr/share/perl5/Debbugs/Packages.pm line 80.

Where can one acquire such a thing?  I tried something crazy just to
make it work.

 # cupt install debbugs
 # debbugsconfig
 created /etc/debbugs/text from template.
 created /etc/debbugs/Maintainers from template.
 created /etc/debbugs/Maintainers.override from template.
 created /etc/debbugs/pseudo-packages.description from template.

 $ cat /etc/debbugs/indices/sources
 extra   main    extra
 sample  main    sample
 sample-doc      main    sample
 test    main    test

4. Searches seem to require a /var/lib/debbugs/spool/index.db:

 $ local-debbugs --daemon --no-detach &
 $ local-debbugs --search severity:serious
 [...]
 MLDBM error: Second level tie failed, "No such file or directory" at /usr/share/perl5/Debbugs/Bugs.pm line 461
 Unable to open /var/lib/debbugs/spool/index.db for reading: No such file or directory at /usr/share/perl5/Debbugs/Bugs.pm line 563.

... and I’m beat.

Ideas?
