Indicates a problem with the DNS request.
Indicates some other unhandled resolver error was encountered.
Location resource
Raised when a lockfile cannot be parsed
An error that occurred during the resolution process
An error caused by searching for a dependency that is completely unknown, i.e. has no versions available whatsoever.
An error caused by attempting to fulfil a dependency that was circular
@note This exception will be thrown iff a {Vertex} is added to a
{DependencyGraph} that has a {DependencyGraph::Vertex#path_to?} an
existing {DependencyGraph::Vertex}
The X509 certificate store holds trusted CA certificates used to verify peer certificates.
The easiest way to create a useful certificate store is:
cert_store = OpenSSL::X509::Store.new cert_store.set_default_paths
This will use your system’s built-in certificates.
If your system does not have a default set of certificates you can obtain a set from Mozilla here: curl.haxx.se/docs/caextract.html (Note that this set does not have an HTTPS download option so you may wish to use the firefox-db2pem.sh script to extract the certificates from a local install to avoid man-in-the-middle attacks.)
After downloading or generating a cacert.pem from the above link you can create a certificate store from the pem file like this:
cert_store = OpenSSL::X509::Store.new cert_store.add_file 'cacert.pem'
The certificate store can be used with an SSLSocket like this:
ssl_context = OpenSSL::SSL::SSLContext.new ssl_context.cert_store = cert_store tcp_socket = TCPSocket.open 'example.com', 443 ssl_socket = OpenSSL::SSL::SSLSocket.new tcp_socket, ssl_context
This class walks a YAML AST, converting each node to Ruby
File-based session storage class.
Implements session storage as a flat file of ‘key=value’ values. This storage type only works directly with String values; the user is responsible for converting other types to Strings when storing and from Strings when retrieving.
In-memory session storage class.
Implements session storage as a global in-memory hash. Session data will only persist for as long as the Ruby interpreter instance does.
Dummy session storage class.
Implements session storage place holder. No actual storage will be done.
PStore-based session storage class.
This builds upon the top-level PStore class provided by the library file pstore.rb. Session data is marshalled and stored in a file. File locking and transaction services are provided.
