Subclass of Zlib::Error

When zlib returns a Z_MEM_ERROR, usually if there was not enough memory.

Subclass of Zlib::Error. This error is raised when the zlib stream is currently in progress.

For example:

inflater = Zlib::Inflate.new
inflater.inflate(compressed) do
  inflater.inflate(compressed) # Raises Zlib::InProgressError
end

Zlib::GzipReader is the class for reading a gzipped file. GzipReader should be used as an IO, or -IO-like, object.

Zlib::GzipReader.open('hoge.gz') {|gz|
  print gz.read
}

File.open('hoge.gz') do |f|
  gz = Zlib::GzipReader.new(f)
  print gz.read
  gz.close
end

Method Catalogue

The following methods in Zlib::GzipReader are just like their counterparts in IO, but they raise Zlib::Error or Zlib::GzipFile::Error exception if an error was found in the gzip file.

• each

• each_line

• each_byte

• gets

• getc

• lineno

• lineno=

• read

• readchar

• readline

• readlines

• ungetc

Be careful of the footer of the gzip file. A gzip file has the checksum of pre-compressed data in its footer. GzipReader checks all uncompressed data against that checksum at the following cases, and if it fails, raises Zlib::GzipFile::NoFooter, Zlib::GzipFile::CRCError, or Zlib::GzipFile::LengthError exception.

• When an reading request is received beyond the end of file (the end of compressed data). That is, when Zlib::GzipReader#read, Zlib::GzipReader#gets, or some other methods for reading returns nil.

• When Zlib::GzipFile#close method is called after the object reaches the end of file.

• When Zlib::GzipReader#unused method is called after the object reaches the end of file.

The rest of the methods are adequately described in their own documentation.

exception to wait for reading by EAGAIN. see IO.select.

exception to wait for reading by EWOULDBLOCK. see IO.select.

exception to wait for writing by EINPROGRESS. see IO.select.

The error thrown when the parser encounters illegal CSV formatting.

Error raised by the DRb module when an attempt is made to refer to the context’s current drb server but the context does not have one. See current_server.

Error raised by a dRuby protocol when it doesn’t support the scheme specified in a URI. See DRb::DRbProtocol.

Class representing a drb server instance.

A DRbServer must be running in the local process before any incoming dRuby calls can be accepted, or any local objects can be passed as dRuby references to remote processes, even if those local objects are never actually called remotely. You do not need to start a DRbServer in the local process if you are only making outgoing dRuby calls passing marshalled parameters.

Unless multiple servers are being used, the local DRbServer is normally started by calling DRb.start_service.

Raised when the provided IP address is an invalid address.

Raised when the address family is invalid such as an address with an unsupported family, an address with an inconsistent family, or an address who’s family cannot be determined.

Raised when the address is an invalid length.

ReadTimeout, a subclass of Timeout::Error, is raised if a chunk of the response cannot be read within the read_timeout.

Represents SMTP error code 4xx, a temporary error.
