Bump phpunit version and remove minimum-stability flag

[mpalourdio]

The minimum-stability flag seems useless now, please correct me if it's not the case.
phpunit has been bumped to allow ZF 2.5 compliance.

Was minimum-stability set to allow "doctrine/common": ">=2.4,<2.6-dev" ?
If so, I can cancel the last commit or set the version to ~2.4, let me know

@Ocramius have you feedback about this change?
We are working into the master branch for 1.0.0 stable release and this is a good change.. 👍 ~2.4 :)

I was wondering why travis could only get zf 2.4.2 (except on hhvm, see travis logs). I just remembered a problem I had yesterday.

Now that the main repository has been splitted, Zend\Ldap requires ext/ldap. As the extension in not avalaible on travis, composer fallbacks to 2.4.2.

Any workaround regarding php extension and travis you are aware of ? We have the same problem with the PR I submitted to DoctrineORMModule unfortunately.

I watched Zend\Ldap travis config, but they didn't have the problem because they get dependencies via composer require --dev --no-update

[mpalourdio]

Ok, so I could add a .travis.ini to load ldap.so, seems to work fine, except for php 5.4 that still download ZF 2.4.2, which is ok as ZF 2.5 requires php 5.5+

Also, php7 builds fail on the bash check, I suspect the missing quotes around hhvm. Isn't weird that the coverage is only on for hhvm ? It doesn't look very judicious to me regarding the build matrix.

I think we should allow coverage for all php versions, excepted for hhvm and php7. What do you think ?

[mpalourdio]

There it is. I have had a rough time with travis to have all the builds back to green !

[mpalourdio]

See here for eventually a workaround before considering a merge zendframework/zendframework#7569

[mpalourdio]

\o/, this is fixed in zendframework/zendframework#7571. Some commits are still relevant anyway. I can reset and/or squash what is worth.

[mpalourdio]

I've added a commit that fixes the builds. It is relevant as with phpunit 4.*, hhvm reports a wrong covering percentage, and with php7, xdebug is not loaded, so no coverage at all.

Thanks!
