A FetchError exception wraps up the various possible IO and HTTP failures that could happen while downloading from the internet.
The SpecFetcherSetup allows easy setup of a remote source in RubyGems tests:
spec_fetcher do |f| f.gem 'a', 1 f.spec 'a', 2 f.gem 'b', 1' 'a' => '~> 1.0' end
The above declaration creates two gems, a-1 and b-1, with a dependency from b to a. The declaration creates an additional spec a-2, but no gem for it (so it cannot be installed).
After the gems are created they are removed from Gem.dir.
Raised by Encoding and String methods when the source encoding is incompatible with the target encoding.
This exception is raised if a generator or unparser error occurs.
Thrown when PTY::check is called for a pid that represents a process that has exited.
Socket::AncillaryData represents the ancillary data (control information) used by sendmsg and recvmsg system call. It contains socket family, control message (cmsg) level, cmsg type and cmsg data.
Subclass of Zlib::Error when zlib returns a Z_DATA_ERROR.
Usually if a stream was prematurely freed.
Zlib::Deflate is the class for compressing data. See Zlib::ZStream for more information.
Zlib:Inflate is the class for decompressing compressed data. Unlike Zlib::Deflate, an instance of this class is not able to duplicate (clone, dup) itself.
Objects of class File::Stat encapsulate common status information for File objects. The information is recorded at the moment the File::Stat object is created; changes made to the file after that point will not be reflected. File::Stat objects are returned by IO#stat, File::stat, File#lstat, and File::lstat. Many of these methods return platform-specific values, and not all values are meaningful on all systems. See also Kernel#test.
An ObjectSpace::WeakMap object holds references to any objects, but those objects can get garbage collected.
This class is mostly used internally by WeakRef, please use lib/weakref.rb for the public interface.
