The only type of request job remaining was "install" which is really a
root requirement. The only other kind of input for the solver is now a
set of fixed packages.
Rules have been updated to account for only two kinds of former job
reason: FIXED or ROOT_REQUIRE. The job property has always been
redundant and has been removed, since reasonData suffices.
Problem reasons are always rules, so the unnecessary wrapping in an
array has been removed.
We now only ever generate a single rule per root require or fixed
package, so there is no need for the solver to special handle disabling
"jobs" anymore, the rule can just be disabled as usual.
For consistency special handling of rules for jobs in problems has been
integrated into the rule class like all other rule reasons. As part of
this change the error message for root requirements has been improved a
bit to make it clearer where the package installation request came from.
The word job has also been removed from operations, which are called
operations, not jobs.
Currently, preferred-install accepts the hash of patterns as the value in the composer.json. I've followed the same approach as used in extra and platform for letting the user define install preferences through CLI in the format: `composer config preferred-install my-organization/stable-package.dist`.
This includes two breaking changes:
- the hostname is not resolved in the case of an IP address.
- a hostname with a trailing period (FQDN) is not matched.
This brings the basic implementation in line with curl behaviour, with
the addition of full IP address and range matching (curl does not
differentiate between IP addresses host names).
The NO_PROXY environment variable can be set to either a comma-separated
list of host names that should not use a proxy, or single asterisk `*`
to match all hosts.
- Port numbers can be included by prefixing the port with a colon `:`.
- IP addresses can be used, but must be enclosed in square brackets
`[...]` if they include a port number.
- IP address ranges can specified in CIDR notation, separating the IP
address and prefix-length with a forward slash `/`.
We now output an update when only a source or dist ref changes even if
it's a stable version so in these cases the output needs to contain the
ref to make it clear to users what changed
