This is the JSON generator implemented as a C extension. It can be configured to be used by setting
JSON.generator = JSON::Ext::Generator
with the method generator= in JSON.
@!visibility private @see DependencyGraph#detach_vertex_named
Indicates some other unhandled resolver error was encountered.
IO wrapper that allows writing a limited amount of data
Raised when a lockfile cannot be parsed
A state that encapsulates a set of {#requirements} with an {Array} of possibilities
A state that encapsulates a single possibility to fulfill the given {#requirement}
@!visibility private
Provides information about specifications and dependencies to the resolver, allowing the {Resolver} class to remain generic while still providing power and flexibility.
This module contains the methods that users of Gem::Resolver::Molinillo must to implement, using knowledge of their own model classes.
Delegates all {Gem::Resolver::Molinillo::ResolutionState} methods to a ‘#state` property.
Delegates all {Gem::Resolver::Molinillo::SpecificationProvider} methods to a ‘#specification_provider` property.
Returns the hostname.
p Socket.gethostname #=> "hal"
Note that it is not guaranteed to be able to convert to IP address using gethostbyname, getaddrinfo, etc. If you need local IP address, use Socket.ip_address_list.
Use Addrinfo.getaddrinfo instead. This method is deprecated for the following reasons:
The 3rd element of the result is the address family of the first address. The address families of the rest of the addresses are not returned.
Uncommon address representation: 4/16-bytes binary string to represent IPv4/IPv6 address.
gethostbyname() may take a long time and it may block other threads. (GVL cannot be released since gethostbyname() is not thread safe.)
This method uses gethostbyname() function already removed from POSIX.
This method obtains the host information for hostname.
p Socket.gethostbyname("hal") #=> ["localhost", ["hal"], 2, "\x7F\x00\x00\x01"]
Use Addrinfo.getaddrinfo instead. This method is deprecated for the following reasons:
The 3rd element of the result is the address family of the first address. The address families of the rest of the addresses are not returned.
gethostbyname() may take a long time and it may block other threads. (GVL cannot be released since gethostbyname() is not thread safe.)
This method uses gethostbyname() function already removed from POSIX.
This method lookups host information by hostname.
TCPSocket.gethostbyname("localhost") #=> ["localhost", ["hal"], 2, "127.0.0.1"]
