[WIP] V3 readiness

[mtymek]

This PR prepares zend-view for supporting ServiceManager v3.

• update repository according to migration/compatibility guide
• fix failing tests for SMv2
• fix failing tests for SMv3
• ensure everything works together after zend-mvc is v3-compatible

Last element is blocked by zendframework/zend-cache#68 - SMv3 cannot be installed at this moment because cache component is not V3-ready.

Edit: zend-cache was fixed, apparently zend-mvc is the blocker now.

This will need to check for a different exception depending on whether it's run under v2 or v3. Easiest way is to call a getInvalidServiceException() method in the same way the CommonPluginManagerTrait does. Or, if it's not a whole load of retooling, use the trait in this test and ditch the compatibility test.

Good stuff! Don't forget to add this to https://github.com/zendframework/maintainers/wiki/ZF3-ServiceManager-component-refactors,-phase-2

I updated the code according to kynx's feedback. I tested it with ServiceManager v3 (by temporarily setting required version as 3.0.3 as 2.8.0), and then I saw only 7 tests failing, apparently all related to zend-mvc being not compatible yet - apparently it is the last blocker.
I will wait until it is ready, and then do the final check.

@mtymek The approach I've been using for dependencies that are in the require-dev section, but which do not yet have forwards-compat releases, is as follows:

• When testing on travis-ci against servicemanager and/or eventmanager v3, remove the dependency (composer remove --no-update zendframework/zend-such-and-such).
• Find tests related to the component, and mark them skipped, with a message indicating they should be re-enabled once the component has forwards-compat releases.

This works in most situations, particularly when we start seeing circular dependencies (essentially, any zend-mvc dependency observed is likely a circular dependency at this point).

In this particular component, we have forwards-compat changes for a good portion of the components listed in the require-dev section, and all items in require have stable forwards-compat releases. If the only tests failing currently are due to zend-mvc, we can safely use this approach.

I'm willing to do that work today when merging; zend-view is a dep for a number of other components (navigation and form in particular), so this would help unblock some of those.

Separate the FQCN and normalized names, and group them by type. This will allow us to remove the normalized versions more easily at a later date. (I can do this on merge if needed.)

[mtymek]

• separated FQCN from normalized name
• switched "Config" to lowercase

[mtymek]

As per your suggestion, I marked some tests as "skipped". Unfortunately I still get some errors in PluginManagerCompatibilityTest under v3, that I'm not able to resolve:

How can I work around it?

edit: pasted wrong error before...

[weierophinney]

@mtymek ha! I've already pulled locally to review!

In that particular case, the plugin requires zend-session, which does not have a forwards-compat version yet. As such, I'd override the aliasProvider() method and have it skip that alias; you can see an example of that in the FilterPluginManagerCompatibilityTest.

Since I'm in the process of review anyways, I can do that for you if you'd like.

[mtymek]

OK, please do - I was about to finish for today :-)

[weierophinney]

Merged with #42!
