Bundler::Persistent::Net::HTTP::Persistent

Persistent connections for Net::HTTP

Bundler::Persistent::Net::HTTP::Persistent maintains persistent connections across all the servers you wish to talk to. For each host:port you communicate with a single persistent connection is created.

Multiple Bundler::Persistent::Net::HTTP::Persistent objects will share the same set of connections.

For each thread you start a new connection will be created. A Bundler::Persistent::Net::HTTP::Persistent connection will not be shared across threads.

You can shut down the HTTP connections when done by calling shutdown. You should name your Bundler::Persistent::Net::HTTP::Persistent object if you intend to call this method.

Example:

require 'bundler/vendor/net-http-persistent/lib/net/http/persistent'

uri = Bundler::URI 'http://example.com/awesome/web/service'

http = Bundler::Persistent::Net::HTTP::Persistent.new name: 'my_app_name'

# perform a GET
response = http.request uri

# or

get = Net::HTTP::Get.new uri.request_uri
response = http.request get

# create a POST
post_uri = uri + 'create'
post = Net::HTTP::Post.new post_uri.path
post.set_form_data 'some' => 'cool data'

# perform the POST, the Bundler::URI is always required
response http.request post_uri, post

Note that for GET, HEAD and other requests that do not have a body you want to use Bundler::URI#request_uri not Bundler::URI#path. The request_uri contains the query params which are sent in the body for other requests.

SSL ↑

SSL connections are automatically created depending upon the scheme of the Bundler::URI. SSL connections are automatically verified against the default certificate store for your computer. You can override this by changing #verify_mode or by specifying an alternate cert_store.

Here are the SSL settings, see the individual methods for documentation:

certificate

This client’s certificate

ca_file

The certificate-authorities

ca_path

Directory with certificate-authorities

cert_store

An SSL certificate store

ciphers

List of SSl ciphers allowed

private_key

The client’s SSL private key

reuse_ssl_sessions

Reuse a previously opened SSL session for a new connection

ssl_timeout

SSL session lifetime

ssl_version

Which specific SSL version to use

verify_callback

For server certificate verification

verify_depth

Depth of certificate verification

verify_mode

How connections should be verified

Proxies ↑

A proxy can be set through proxy= or at initialization time by providing a second argument to ::new. The proxy may be the Bundler::URI of the proxy server or :ENV which will consult environment variables.

See proxy= and proxy_from_env for details.

Headers ↑

Headers may be specified for use in every request. headers are appended to any headers on the request. override_headers replace existing headers on the request.

The difference between the two can be seen in setting the User-Agent. Using http.headers['User-Agent'] = 'MyUserAgent' will send “Ruby, MyUserAgent” while http.override_headers['User-Agent'] = 'MyUserAgent' will send “MyUserAgent”.

Tuning ↑

Segregation ↑

By providing an application name to ::new you can separate your connections from the connections of other applications.

Idle Timeout ↑

If a connection hasn’t been used for this number of seconds it will automatically be reset upon the next use to avoid attempting to send to a closed connection. The default value is 5 seconds. nil means no timeout. Set through idle_timeout.

Reducing this value may help avoid the “too many connection resets” error when sending non-idempotent requests while increasing this value will cause fewer round-trips.

Read Timeout ↑

The amount of time allowed between reading two chunks from the socket. Set through read_timeout

Max Requests ↑

The number of requests that should be made before opening a new connection. Typically many keep-alive capable servers tune this to 100 or less, so the 101st request will fail with ECONNRESET. If unset (default), this value has no effect, if set, connections will be reset on the request after max_requests.

Open Timeout ↑

The amount of time to wait for a connection to be opened. Set through open_timeout.

Socket Options ↑

Socket options may be set on newly-created connections. See socket_options for details.

Non-Idempotent Requests ↑

By default non-idempotent requests will not be retried per RFC 2616. By setting #retry_change_requests to true requests will automatically be retried once.

Only do this when you know that retrying a POST or other non-idempotent request is safe for your application and will not create duplicate resources.

The recommended way to handle non-idempotent requests is the following:

require 'bundler/vendor/net-http-persistent/lib/net/http/persistent'

uri = Bundler::URI 'http://example.com/awesome/web/service'
post_uri = uri + 'create'

http = Bundler::Persistent::Net::HTTP::Persistent.new name: 'my_app_name'

post = Net::HTTP::Post.new post_uri.path
# ... fill in POST request

begin
  response = http.request post_uri, post
rescue Bundler::Persistent::Net::HTTP::Persistent::Error

  # POST failed, make a new request to verify the server did not process
  # the request
  exists_uri = uri + '...'
  response = http.get exists_uri

  # Retry if it failed
  retry if response.code == '404'
end

The method of determining if the resource was created or not is unique to the particular service you are using. Of course, you will want to add protection from infinite looping.

Connection Termination ↑

If you are done using the Bundler::Persistent::Net::HTTP::Persistent instance you may shut down all the connections in the current thread with shutdown. This is not recommended for normal use, it should only be used when it will be several minutes before you make another HTTP request.

If you are using multiple threads, call shutdown in each thread when the thread is done making requests. If you don’t call shutdown, that’s OK. Ruby will automatically garbage collect and shutdown your HTTP connections when the thread terminates.

Attributes

ca_file[R]

An SSL certificate authority. Setting this will set #verify_mode to VERIFY_PEER.

ca_path[R]

A directory of SSL certificates to be used as certificate authorities. Setting this will set #verify_mode to VERIFY_PEER.

cert[R]

This client’s OpenSSL::X509::Certificate

cert_store[R]

An SSL certificate store. Setting this will override the default certificate store. See #verify_mode for more information.

certificate[R]

This client’s OpenSSL::X509::Certificate

ciphers[R]

The ciphers allowed for SSL connections

debug_output[RW]

Sends #debug_output to this IO via Net::HTTP#set_debug_output.

Never use this method in production code, it causes a serious security hole.

headers[R]

Headers that are added to every request using Net::HTTP#add_field

http_versions[R]

Maps host:port to an HTTP version. This allows us to enable version specific features.

idle_timeout[RW]

Maximum time an unused connection can remain idle before being automatically closed.

keep_alive[RW]

The value sent in the Keep-Alive header. Defaults to 30. Not needed for HTTP/1.1 servers.

This may not work correctly for HTTP/1.0 servers

This method may be removed in a future version as RFC 2616 does not require this header.

key[R]

This client’s SSL private key

max_requests[RW]

Maximum number of requests on a connection before it is considered expired and automatically closed.

max_version[R]

Maximum SSL version to use, e.g. :TLS1_2

By default, the version will be negotiated automatically between client and server. Ruby 2.5 and newer only.

min_version[R]

Minimum SSL version to use, e.g. :TLS1_1

By default, the version will be negotiated automatically between client and server. Ruby 2.5 and newer only.

name[R]

A name for this connection. Allows you to keep your connections apart from everybody else’s.

no_proxy[R]

List of host suffixes which will not be proxied

open_timeout[RW]

Seconds to wait until a connection is opened. See Net::HTTP#open_timeout

override_headers[R]

Headers that are added to every request using Net::HTTP#[]=

private_key[R]

This client’s SSL private key

proxy_uri[R]

The URL through which requests will be proxied

read_timeout[RW]

Seconds to wait until reading one block. See Net::HTTP#read_timeout

retry_change_requests[RW]

Enable retries of non-idempotent requests that change data (e.g. POST requests) when the server has disconnected.

This will in the worst case lead to multiple requests with the same data, but it may be useful for some applications. Take care when enabling this option to ensure it is safe to POST or perform other non-idempotent requests to the server.

reuse_ssl_sessions[RW]

By default SSL sessions are reused to avoid extra SSL handshakes. Set this to false if you have problems communicating with an HTTPS server like:

SSL_connect [...] read finished A: unexpected message (OpenSSL::SSL::SSLError)
socket_options[R]

An array of options for Socket#setsockopt.

By default the TCP_NODELAY option is set on sockets.

To set additional options append them to this array:

http.socket_options << [Socket::SOL_SOCKET, Socket::SO_KEEPALIVE, 1]
ssl_timeout[R]

SSL session lifetime

ssl_version[R]

SSL version to use.

By default, the version will be negotiated automatically between client and server. Ruby 1.9 and newer only. Deprecated since Ruby 2.5.

verify_callback[R]

SSL verification callback. Used when #ca_file or #ca_path is set.

verify_depth[R]

Sets the depth of SSL certificate verification

verify_mode[R]

HTTPS verify mode. Defaults to OpenSSL::SSL::VERIFY_PEER which verifies the server certificate.

If no #ca_file, #ca_path or #cert_store is set the default system certificate store is used.

You can use verify_mode to override any default values.

write_timeout[RW]

Seconds to wait until writing one block. See Net::HTTP#write_timeout

Public Class Methods

detect_idle_timeout(uri, max = 10) click to toggle source

Use this method to detect the idle timeout of the host at uri. The value returned can be used to configure idle_timeout. max controls the maximum idle timeout to detect.

After

Idle timeout detection is performed by creating a connection then performing a HEAD request in a loop until the connection terminates waiting one additional second per loop.

NOTE: This may not work on ruby > 1.9.

 
               # File bundler/vendor/net-http-persistent/lib/net/http/persistent.rb, line 251
def self.detect_idle_timeout uri, max = 10
  uri = Bundler::URI uri unless Bundler::URI::Generic === uri
  uri += '/'

  req = Net::HTTP::Head.new uri.request_uri

  http = new 'net-http-persistent detect_idle_timeout'

  http.connection_for uri do |connection|
    sleep_time = 0

    http = connection.http

    loop do
      response = http.request req

      $stderr.puts "HEAD #{uri} => #{response.code}" if $DEBUG

      unless Net::HTTPOK === response then
        raise Error, "bad response code #{response.code} detecting idle timeout"
      end

      break if sleep_time >= max

      sleep_time += 1

      $stderr.puts "sleeping #{sleep_time}" if $DEBUG
      sleep sleep_time
    end
  end
rescue
  # ignore StandardErrors, we've probably found the idle timeout.
ensure
  return sleep_time unless $!
end
new(name: nil, proxy: nil, pool_size: DEFAULT_POOL_SIZE) click to toggle source

Creates a new Bundler::Persistent::Net::HTTP::Persistent.

Set name to keep your connections apart from everybody else’s. Not required currently, but highly recommended. Your library name should be good enough. This parameter will be required in a future version.

proxy may be set to a Bundler::URI::HTTP or :ENV to pick up proxy options from the environment. See #proxy_from_env for details.

In order to use a Bundler::URI for the proxy you may need to do some extra work beyond Bundler::URI parsing if the proxy requires a password:

proxy = Bundler::URI 'http://proxy.example'
proxy.user     = 'AzureDiamond'
proxy.password = 'hunter2'

Set pool_size to limit the maximum number of connections allowed. Defaults to 1/4 the number of allowed file handles. You can have no more than this many threads with active HTTP transactions.

Sets the proxy server. The proxy may be the Bundler::URI of the proxy server, the symbol :ENV which will read the proxy from the environment or nil to disable use of a proxy. See proxy_from_env for details on setting the proxy from the environment.

If the proxy Bundler::URI is set after requests have been made, the next request will shut-down and re-open all connections.

The no_proxy query parameter can be used to specify hosts which shouldn’t be reached via proxy; if set it should be a comma separated list of hostname suffixes, optionally with :port appended, for example example.com,some.host:8080.

proxy_from_env() click to toggle source

Creates a Bundler::URI for an HTTP proxy server from ENV variables.

If HTTP_PROXY is set a proxy will be returned.

If HTTP_PROXY_USER or HTTP_PROXY_PASS are set the Bundler::URI is given the indicated user and password unless HTTP_PROXY contains either of these in the Bundler::URI.

The NO_PROXY ENV variable can be used to specify hosts which shouldn’t be reached via proxy; if set it should be a comma separated list of hostname suffixes, optionally with :port appended, for example example.com,some.host:8080. When set to * no proxy will be returned.

For Windows users, lowercase ENV variables are preferred over uppercase ENV variables.

request(uri, req = nil, &block) click to toggle source

Makes a request on uri. If req is nil a Net::HTTP::Get is performed against uri.

If a block is passed request behaves like Net::HTTP#request (the body of the response will not have been read).

req must be a Net::HTTPGenericRequest subclass (see Net::HTTP for a list).

If there is an error and the request is idempotent according to RFC 2616 it will be retried automatically.

The SSL HTTP connection to:

  #{connection.address}:#{connection.port}

                           !!!MAY NOT BE VERIFIED!!!

On your platform your OpenSSL implementation is broken.

There is no difference between the values of VERIFY_NONE and VERIFY_PEER.

This means that attempting to verify the security of SSL connections may not
work.  This exposes you to man-in-the-middle exploits, snooping on the
contents of your connection and other dangers to the security of your data.

To disable this warning define the following constant at top-level in your
application:

  I_KNOW_THAT_OPENSSL_VERIFY_PEER_EQUALS_VERIFY_NONE_IS_WRONG = nil

      WARNING
