在运行Ubuntu 12.04的Travis CI上使用APCu

Question

I have a Symfony-application which is dependent on APCu ( php5-apcu ). The server is running PHP 5.6 on Ubuntu 15.04. APCu is required as a dependency through composer, ie:

"require": {
    "ext-apc": "~4.0"
}

Which works great. Trying to get the application running on Travis-CI, isn't as smooth, since they run Ubuntu 12.04, which doesn't have the php5-apcu package, which yields:

E: Unable to locate package php5-apcu

Installing php-apc doesn't satisfy the ext-apcu requirement, and I'd prefer not to promote deprecated packages.

Any suggestions on how to setup APCu on Travis CI? Preferably without manually downloading the package.

Answer 1

You can easily install the apcu extension from pecl.

Here is an example .travis.yml file:

language: php

php:
  - 5.6

before_script:
  - pear config-set preferred_state beta
  - yes '' | pecl install apcu

script:
  - cd tests/ && phpunit

If you need a more complex solution, for example multiple php versions, you should be able to easily adopt the solution from the doctrine/cache repository ( https://github.com/doctrine/cache/blob/master/.travis.yml ). They run the tests against php 5.3 - 5.6 and hhvm with the following before_script:

[...]
before_script:
    - [...]
    - sh -c "if [[ $TRAVIS_PHP_VERSION != 'hhvm' && `php-config --vernum` -ge 50500 ]] ; then pecl config-set preferred_state beta; printf "yes\n" | pecl install apcu ; else echo 'extension="apc.so"' >> ./tests/travis/php.ini ;fi"
    - [...]
[...]

Happy testing
