Subject: php-monolog: Versionned Provides field

Date: Wed, 07 Jan 2015 22:23:24 +0100

Package: php-monolog
Version: 1.12.0-1
Severity: serious
Justification: Policy 7.1

  Hi,

  Your package in experimental declare a versionned Provides field.
It is wrong, and this has been catched by lintian:
https://lintian.debian.org/maintainer/pkg-php-pear@lists.alioth.debian.org.html#php-monolog
https://lintian.debian.org/tags/versioned-provides.html

  This bug is present for one week. Can you correct it quickly? The reason
is that apt-get complain about it:
# apt-get update
[...]
W: Ignoring Provides line with DepCompareOp for package php-psr-log-implementation
W: Vous pouvez lancer « apt-get update » pour corriger ces problèmes.
#

  So, for one week, for each machine where I use apticron with the
experimental repo listed in my sources, I get a mail per day about this error.

  I agree that, per se, this bug is a very little bug for php-monolog (ie no
local consequences). But, as it is catched by apt-get and leads to spurious
output, it has consequences on other unrelated software (especially apticron in
my case). So I would be very pleased if you can fix it quickly.

  Regards,
    Vincent

Indeed, as supported by apt since 1.0.7 (#758153) and dpkg since
1.17.11.

Not really, but the lack of support in (soon to be old)stable makes it
annoying.

There are at least three other options I can think of:
- not using an experimental repository in a stable environment;
- using a more recent apt on machine where an experimental repository is
  needed;
- make apt (or apticron) ignore such error and get this change accepted
  in the next stable update.

The third possibility may make sense in the near future, so we can start
benefiting of this feature early in Strech development, without people
using Wheezy being bored by the same kind of error messages if they have
an unstable or testing repository in their sources.list

>   I agree that, per se, this bug is a very little bug for php-monolog

Indeed, keeping it open if you wish to reassign it to apt.
(“bts reopen 758153 , reassign 774815 apt , forcemerge 758153 774815 , \
  affects 758153 php-monolog” could be another option.)

I'm very glad to learn that this feature seems supported by
apt and dpkg now. I did not know.

It also against the current policy:
From https://www.debian.org/doc/debian-policy/ch-relationships.html:
> All of the fields except for Provides may restrict their applicability to
> particular versions of each named package.

So a bug should probably be filled against the policy (and then against
lintian to remove or fix the current check).

Note that using experimental (ie installing packages from experimental)
is not required to suffer from the problem. Just having experimental
in sources.list is enough.

As the relation ship was not an error as I was thinking but
the use of a new future feature, I will find local workaround.

I do not have enough time today. If nobody does it before, I will try
to do it in a few days (and also opening bugs against policy and lintian)

There is #761219 already, feel free improve the proposed patch or second
it.
