With this change, composer will automatically call dev/build after an update or install
command. The main reason that this is 3.1-only is that previous releases would have
necessitated the use of 'sudo -u www-data', which is too environment-specific.
One thing that this may cause problems with is 'composer create-project' in an environment
without a _ss_environment file. It will call dev/build, and dev/build will throw an
error. That should be fixed in a subsequent commit.
Now that https://github.com/composer/composer/pull/1883 is in Composer, self.version
will work as a requirement for framework & cms. This will simplify the release
process a great deal.
Ultimately, the release of rc1 will be the place to test that, but it seems appropriate
to get this in there for that.
If it succeeds with 3.1-rc1, I'd suggest we backport to 3.0 and 2.4.
Any "composer require <module>" call will first call
a "composer update". This *automatically* includes dev requirements,
without providing a way to turn off this behaviour.
A workaround would be "composer require --no-update <module> && composer update --no-dev <module>",
but that drastically reduces the usefulness of the command
for our target audience (moderately technical devs).
In the end, the small faction of devs needing the dev dependencies
also know how to install them on their own. And having a local phpunit
build actually gets in the way more than it helps in case you have
it installed through PEAR already (can get really weird when using the
PEAR provided "phpunit" binary, but the autoloader finds the composer managed classes).
They used to require manual editing of the composer.json
file in order to do a proper dev checkout. In the end,
the choice between release tag and dev branch should
be handled by composer already via the --stability flag.
When using create-project, self.version doesnt work - the checkout looses the reference to the version
Fix by explicity referencing the version instead
