Gem::StreamUI implements a simple stream based user interface.
Validator performs various gem file and gem database validation
RefError is raised when a referenced object has been recycled by the garbage collector
Raised on attempt to Ractor#take if there was an uncaught exception in the Ractor. Its cause will contain the original exception, and ractor is the original ractor it was raised in.
r = Ractor.new { raise "Something weird happened" } begin r.take rescue => e p e # => #<Ractor::RemoteError: thrown by remote Ractor.> p e.ractor == r # => true p e.cause # => #<RuntimeError: Something weird happened> end
AbstractSyntaxTree provides methods to parse Ruby code into abstract syntax trees. The nodes in the tree are instances of RubyVM::AbstractSyntaxTree::Node.
This module is MRI specific as it exposes implementation details of the MRI abstract syntax tree.
This module is experimental and its API is not stable, therefore it might change without notice. As examples, the order of children nodes is not guaranteed, the number of children nodes might change, there is no way to access children nodes by name, etc.
If you are looking for a stable API or an API working under multiple Ruby implementations, consider using the parser gem or Ripper. If you would like to make RubyVM::AbstractSyntaxTree stable, please join the discussion at bugs.ruby-lang.org/issues/14844.
Helper methods for both Gem::Installer and Gem::Uninstaller
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.
A StoreContext is used while validating a single certificate and holds the status involved.
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 extracted from Mozilla CA certificate store by cURL maintainers here: curl.haxx.se/docs/caextract.html (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.verify_mode = OpenSSL::SSL::VERIFY_PEER ssl_context.cert_store = cert_store tcp_socket = TCPSocket.open 'example.com', 443 ssl_socket = OpenSSL::SSL::SSLSocket.new tcp_socket, ssl_context
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.
Dummy session storage class.
Implements session storage place holder. No actual storage will be done.
Authenticator for the “DIGEST-MD5” authentication type. See authenticate().
Error raised upon a “NO” response from the server, indicating that the client command could not be completed successfully.
Raised when a bad requirement is encountered
The RequirementList is used to hold the requirements being considered while resolving a set of gems.
The RequirementList acts like a queue where the oldest items are removed first.
An absolutely silent progress reporter.
A basic dotted progress reporter.
A progress reporter that prints out messages about the current progress.
A progress reporter that behaves nicely with threaded downloading.
