PHP 7 is now out, and Travis-CI supports it as part of their standard configuration (rather than forcing you to use the PHP nightly build). Last night I submitted a pull request to add PHP 7 support to the Known Travis build, which was a little bit problematic.

Known uses Apache + PHP-FPM, rather than the Travis default nginx setup, and while there are guides for getting this working on the Travis site, it seems that they’re not quite there for the PHP 7 build.

The PHP 7 build was running into this error:

[15-Feb-2016 23:14:58] WARNING: Nothing matches the include pattern '/home/travis/.phpenv/versions/7.0.3/etc/php-fpm.d/*.conf' from /home/travis/.phpenv/versions/7.0.3/etc/php-fpm.conf at line 125.
[15-Feb-2016 23:14:58] ERROR: No pool defined. at least one pool section must be specified in config file

/home/travis/build.sh: line 45: 25862 Segmentation fault      (core dumped) ~/.phpenv/versions/$(phpenv version-name)/sbin/php-fpm

This took a little while to diagnose, but in the end the fix was pretty simple. Basically it looks like the Travis PHP7 build of PHP-FPM expects, but can not find, a pool definition. You don’t need to customise it, just put a default one into PHP-FPM’s config directory.

So, I packaged a default template with the Known patch, and in my .travis.yml added the following to before_script:

- if [[ ${TRAVIS_PHP_VERSION:0:3} == "7.0" ]]; then sudo cp Tests/build/www.conf ~/.phpenv/versions/$(phpenv version-name)/etc/php-fpm.d/; fi

I also modified the Apache vhost example and added ServerName localhost to the definition (although this might not be needed).

After this, the build completes successfully.

PHP7 is new, so I suspect Travis will fix this shortly. However, hopefully this will prevent some hair-pulling in the mean time!
