[pkg-php-pear] Bug#910788: php-codecoverage: autopkgtest needs update for new version of xdebug

[Paul Gevers]

Source: php-codecoverage
Version: 6.0.8+dfsg-1
X-Debbugs-CC: debian-ci at lists.debian.org, xdebug at packages.debian.org
User: debian-ci at lists.debian.org

Dear maintainers,

With a recent upload of xdebug the autopkgtest of php-codecoverage fails
in testing when that autopkgtest is run with the binary packages of
xdebug from unstable. It passes when run with only packages from
testing. In tabular form:
                       pass            fail
xdebug                 from testing    2.7.0~beta1+2.5.5-1
php-codecoverage       from testing    6.0.8+dfsg-1
all others             from testing    from testing

I copied some of the output at the bottom of this report. To be honest,
I am quite puzzled about what is going on. The issue seems very much
like bug 910264 (closed) which fixed itself apparently. I fear that the
test of php-codecoverage has a versioned dependency on some php7.2*
package that it doesn't declare, and due to alternatives, the php7.3*
version gets installed and doesn't do the right thing for the test.
Apart from the output, I also attach the delta of installed packages
between a successful run and the failing one.

Currently this regression is contributing to the delay of the migration
of xdebug to testing [1]. Of course, xdebug shouldn't just break your
autopkgtest (or even worse, your package), but it seems to me that its
php-codecoverage that needs to improve its (versioned) (test)
dependencies. I could be wrong though, please reassign to xdebug (or any
other package) if you think the issue lies elsewhere.

If this is a real problem in your package (and not only in your
autopkgtest), the right binary package(s) from xdebug should really add
a versioned Breaks on the unfixed version of (one of your) package(s).
Note: the Breaks is nice even if the issue is only in the autopkgtest as
it helps the migration software to figure out the right versions to
combine in the tests.
