add composer.lock & update travis config

[stefanotorresi]

as per zendframework/zendframework#7660

also entails these changes:

• bump minimum php version to 5.6
• add composer scripts entries
• fix travis.yml env variables to not be affected by Environment variables truncated at first whitespace travis-ci/travis-ci#1444
• fix build on php 7

@stefanotorresi You should disable APC and memcache with PHP 7.
Can you update your travis settings?

[marc-mabe]

@thomasvargui In my opinion this travis error has nothing to do with this PR.

It's related to https://pear.php.net/bugs/bug.php?id=21007 and found the way into the repo by #82, #74 and #52.

The problem now is that a test for a race condition is using different PHP processes and installing apc_bc on PHP 7 requires an extension load order where it fails installed by pecl. On travis there is a hack that adds the extension two times. That worked but PHP triggers a warning on startup but the warning gets be detected now because PHPUnit needs to run this race condition test in an own process.

If we fix the extension install / loading completely this issue should be gone

[stefanotorresi]

@thomasvargiu @marc-mabe

fixed by installing apcu_bc manually rather than via PECL

also unsupported php 7 extentions mongo and memcache are now correctly disabled

@marc-mabe ping, I see from IRC that you're working on the same changes I'm doing atm :D let me handle this!

[marc-mabe]

@stefanotorresi ok I'll wait - You can check my changes here https://github.com/marc-mabe/zend-cache/tree/travis_apc_php7 the only issue I have is that in PHP-7 apc.so doesn't get loaded this way I think because I add it to .ci/apcu.so after this file was added

[stefanotorresi]

@marc-mabe should be good now!

[marc-mabe]

@stefanotorresi Looks much better now 👍

But I still have two questions:

• why did you increase the minimum required PHP version? Did I missed something?
• Why do you load apc_bc manuelly instead of using pecl + removing the 'extension=' part from php.ini as in loading apc.so?

[weierophinney]

why did you increase the minimum required PHP version? Did I missed something?

We haven't announced it, but I've talked about it on IRC. Next minor/major versions of all components will be bumped to 5.6, as 5.5 goes EOL next month. @stefanotorresi is making that change along with the composer.lock additions.

[marc-mabe]

@weierophinney Thanks for the info!
I added the BC Break label because of that but I'll also backport the changes to master without the PHP version upgrade as this actually contains a fix for running the tests in travis.

@stefanotorresi I did some additional changes:

• Install lowest, locked and latest versions of apcu(_bc). If we already need to install the extensions we can also install different versions for different runs ;)
  • replace INSTALL_APCU_BC with APCU_BC_PECL_VERSION
• use the variables APCU[_BC]_PECL_VERSION as marker for install and loading ini file conditions
• removed composer self-update as this will be done by travis already
• run composer test scripts as composer run-script test[-coverage] --timeout=XXXX because I run into a timout issue introduced by composer see https://travis-ci.org/marc-mabe/zend-cache/jobs/133889679#L896

You can take a look into the changes here https://github.com/marc-mabe/zend-cache/blob/hotfix/101/.travis.yml
If you don't have any objections I'll merge it tomorrow

[stefanotorresi]

LGTM :)
