Invoked by Timeout.timeout to execute the given block within the given duration. It can also be invoked directly by the scheduler or user code.

Attempt to limit the execution time of a given block to the given duration if possible. When a non-blocking operation causes the block‘s execution time to exceed the specified duration, that non-blocking operation should be interrupted by raising the specified exception_class constructed with the given exception_arguments.

General execution timeouts are often considered risky. This implementation will only interrupt non-blocking operations. This is by design because it’s expected that non-blocking operations can fail for a variety of unpredictable reasons, so applications should already be robust in handling these conditions and by implication timeouts.

However, as a result of this design, if the block does not invoke any non-blocking operations, it will be impossible to interrupt it. If you desire to provide predictable points for timeouts, consider adding +sleep(0)+.

If the block is executed successfully, its result will be returned.

The exception will typically be raised using Fiber#raise.

Iterates over keys and values. Note that unlike other collections, each without block isn’t supported.

Reads the file from pathname, then parses it like ::parse, returning the root node of the abstract syntax tree.

SyntaxError is raised if pathname’s contents are not valid Ruby syntax.

RubyVM::AbstractSyntaxTree.parse_file("my-app/app.rb")
# => #<RubyVM::AbstractSyntaxTree::Node:SCOPE@1:0-31:3>

See ::parse for explanation of keyword argument meaning and usage.

Returns the length of the hash value of the digest.

This method should be overridden by each implementation subclass. If not, digest_obj.digest().length() is returned.

Returns the block length of the digest.

This method is overridden by each implementation subclass.

Consumes size bytes from the buffer

Generates a new key (pair).

If a String is given as the first argument, it generates a new random key for the algorithm specified by the name just as ::generate_parameters does. If an OpenSSL::PKey::PKey is given instead, it generates a new random key for the same algorithm as the key, using the parameters the key contains.

See ::generate_parameters for the details of options and the given block.

Example

pkey_params = OpenSSL::PKey.generate_parameters("DSA", "dsa_paramgen_bits" => 2048)
pkey_params.priv_key #=> nil
pkey = OpenSSL::PKey.generate_key(pkey_params)
pkey.priv_key #=> #<OpenSSL::BN 6277...

Returns the value of field 'Content-Length' as an integer, or nil if there is no such field; see Content-Length request header:

res = Net::HTTP.get_response(hostname, '/nosuch/1')
res.content_length # => 2
res = Net::HTTP.get_response(hostname, '/todos/1')
res.content_length # => nil

Sets the value of field 'Content-Length' to the given numeric; see Content-Length response header:

_uri = uri.dup
hostname = _uri.hostname           # => "jsonplaceholder.typicode.com"
_uri.path = '/posts'               # => "/posts"
req = Net::HTTP::Post.new(_uri)    # => #<Net::HTTP::Post POST>
req.body = '{"title": "foo","body": "bar","userId": 1}'
req.content_length = req.body.size # => 42
req.content_type = 'application/json'
res = Net::HTTP.start(hostname) do |http|
  http.request(req)
end # => #<Net::HTTPCreated 201 Created readbody=true>

Returns the integer representing length of the value of field 'Content-Range', or nil if no such field exists; see Content-Range response header:

res = Net::HTTP.get_response(hostname, '/todos/1')
res['Content-Range'] # => nil
res['Content-Range'] = 'bytes 0-499/1000'
res.range_length     # => 500

Sets header 'Authorization' using the given account and password strings:

req.basic_auth('my_account', 'my_password')
req['Authorization']
# => "Basic bXlfYWNjb3VudDpteV9wYXNzd29yZA=="

Creates an unsigned certificate for subject and key. The lifetime of the key is from the current time to age which defaults to one year.

The extensions restrict the key to the indicated uses.

Creates a new digest instance using the specified algorithm. The default is SHA256.

Creates a new key pair of the specified algorithm. RSA, DSA, and EC are supported.

Enumerates the trusted certificates via Gem::Security::TrustDir.

Simple deprecation method that deprecates name by wrapping it up in a dummy method. It warns on each call to the dummy method telling the user of repl (unless repl is :none) and the Rubygems version that it is planned to go away.

If response is an HTTP Success (2XX) response, yields the response if a block was given or shows the response body to the user.

If the response was not successful, shows an error to the user including the error_prefix and the response body. If the response was a permanent redirect, shows an error to the user including the redirect location.
