+%% Callback that maps the Session-Id of an incoming request to a

+%%
+%% With an options list, maps an id whose optional value is the name

+%% session id has been returned from diameter:session_id/1; otherwise
+%% to a node that has called diameter_dist:attach/1 using the
+%% consistent hashing provided by hash/3, or to the local node() if a
+%% session id could not be extracted or there are no attached nodes. A
+%% handler process is spawned on the selected node using
+%% erlang:spawn_opt/4.
+%%
+%% Different behaviour can be configured by supplying an options map
+%% of the following form:
+%%
+%%   #{search => non_neg_integer(),
+%%     id => [binary()],
+%%     default => discard | local | mfa(),
+%%     dispatch => list() | mfa()}
+%%
+%% The search member limits the number of AVPs that are examined in
+%% the message (from the front), to avoid searching entire message in
+%% case it's known that peers follow RFC 6733's recommendation that
+%% Session-Id be placed at the head of a message. The default is to
+%% search the entire message.
+%%
+%% The id member restricts the optional value mapping to session ids
+%% whose DiamterIdentity is one of those specified. Set this to the
+%% list of Diameter identities advertised by the service in question
+%% (typically one) to ensure that only locally generated session ids
+%% are mapped; or to the empty list to disable the mapping.
+%%
+%% The default member determines where to handle a message whose
+%% Session-Id isn't found or whose optional value isn't mapped to the
+%% name of a connected node. The atom local says the local node, an
+%% MFA is invoked on Session-Id | false, the name of the diameter
+%% service, and the message binary, and should return either a node()
+%% or false to discard the message. Defaults to {diameter_dist, hash, []}.
+%%
+%% The dispatch member determines how the pid() of the request handler
+%% process is retrieved. An MFA is applied to a previously selected
+%% node(), and the module, function, and arguments list to apply in
+%% the handler process to handle the request, the MFA being supplied
+%% by diameter, and returns pid() | discard. A list is equivalent to
+%% {erlang, spawn_opt, []}. Defaults to [].
+%%
+%% This can be used with search = 0 to route on something other than
+%% Session-Id, but this is probably no simpler than just implementing
+%% an own spawn_opt callback. (Except with the default dispatch possibly.)
+%%
+%% Note that if the peer is also implemented with OTP diameter and
+%% generating session ids with diameter:session_id/1 then
+%% route_session/2 can map an optional value to a local node that
+%% happens to have the same name as one of the peer's nodes. This
+%% could lead to an uneven distribution; for example, if the peer
+%% nodes are a subset of the local nodes. In practice, it's typically
+%% known if it's peers or the local node originating sessions; if the
+%% former then setting id = [] disables the optional value mapping, if
+%% the latter then setting default = local disables the hashing.

+	      implements timeouts. The timeout is passed in the <c>tmo</c>
+	      argument and is given in milli seconds. Note that the
+	      <c>tmo</c> argument to these callbacks differ from the
+	      timeout arguments in the <c>ei</c> API. Zero means a zero
+	      timeout. That is, poll and timeout immediately unless the
+	      operation is successful. <c>EI_SCLBK_INF_TMO</c>
+	      (max <c>unsigned</c>) means infinite timeout. The file

+	      If not set, <c>ei</c> will implement the timeout using

+	      The callbacks are not allowed to change between blocking
+	      and non-blocking mode. In order for this to work,
+	      <c>select()</c> needs to interact with the socket primitives
+	      used the same way as it interacts with the ordinary socket
+	      primitives. If this is not the case, the callbacks

+	    Fixed two bugs in the <c>erl_call</c> program. A missing
+	    initialization (introduced in <c>erl_interface-3.11</c>)
+	    which either caused a crash or failure to connect to or
+	    start a node, and an incorrectly calculated timeout which
+	    could cause failure to start an erlang node. These bugs
+	    only caused failures on some platforms.</p>

+    <title>Logger Proxy</title>
+    <p>The Logger proxy is an Erlang process which is part of the
+      Kernel application's supervision tree. During startup, the proxy
+      process registers itself as the <c>system_logger</c>, meaning
+      that log events produced by the emulator are sent to this
+      process.</p>
+    <p>When a log event is issued on a process which has its group
+      leader on a remote node, Logger automatically forwards the log
+      event to the group leader's node. To achieve this, it first
+      sends the log event as an Erlang message from the original
+      client process to the proxy on the local node, and the proxy in
+      turn forwards the event to the proxy on the remote node.</p>
+    <p>When receiving a log event, either from the emulator or from a
+      remote node, the proxy calls the Logger API to log the event.</p>
+    <p>The proxy process is overload protected in the same way as
+      described in
+      section <seealso marker="#overload_protection">Protecting the
+      Handler from Overload</seealso>, but with the following default
+      values:</p>
+    <code>
+    #{sync_mode_qlen => 500,
+      drop_mode_qlen => 1000,
+      flush_qlen => 5000,
+      burst_limit_enable => false,
+      overload_kill_enable => false}</code>
+    <p>For log events from the emulator, synchronous message passing
+      mode is not applicable, since all messages are passed
+      asynchronously by the emulator. Drop mode is achieved by setting
+      the <c>system_logger</c> to <c>undefined</c>, forcing the
+      emulator to drop events until it is set back to the proxy pid
+      again.</p>
+    <p>The proxy uses <seealso marker="erts:erlang#send_nosuspend/2">
+	<c>erlang:send_nosuspend/2</c></seealso> when sending log
+      events to a remote node. If the message could not be sent
+      without suspending the sender, it is dropped. This is to avoid
+      blocking the proxy process.</p>

+	    When user specific file modes are given to the logger

+          <p>
+	    - If <c>raw</c> is not found in the list, it is
+	    added.<br/> - If none of <c>write</c>, <c>append</c> or

+        <item>
+          <p>
+	    The standard logger handler, <c>logger_std_h</c>, now has
+	    a new internal feature for log rotation. The rotation
+	    scheme is as follows:</p>
+          <p>
+	    The log file to which the handler currently writes always
+	    has the same name, i.e. the name which is configured for
+	    the handler. The archived files have the same name, but
+	    with extension ".N", where N is an integer. The newest
+	    archive has extension ".0", and the oldest archive has
+	    the highest number. </p>
+          <p>
+	    The size at which the log file is rotated, and the number
+	    of archive files that are kept, is specified with the
+	    handler specific configuration parameters
+	    <c>max_no_bytes</c> and <c>max_no_files</c> respectively. </p>
+          <p>
+	    Archives can be compressed, in which case they get a
+	    ".gz" file extension after the integer. Compression is
+	    specified with the handler specific configuration
+	    parameter <c>compress_on_rotate</c>.</p>
+          <p>
+	    Own Id: OTP-15479</p>
+        </item>
+        <item>
+          <p>
+	    The new functions <c>logger:i/0</c> and <c>logger:i/1</c>
+	    are added. These provide the same information as
+	    <c>logger:get_config/0</c> and other
+	    <c>logger:get_*_config</c> functions, but the information
+	    is more logically sorted and more readable.</p>

+        </item>
+        <item>
+          <p>
+	    Logger is now protected against overload due to massive
+	    amounts of log events from the emulator or from remote
+	    nodes.</p>
+          <p>
+	    Own Id: OTP-15601</p>
+        </item>
+        <item>
+          <p>
+	    Logger now uses os:system_time/1 instead of
+	    erlang:system_time/1 to generate log event timestamps.</p>
+          <p>
+	    Own Id: OTP-15625</p>
+        </item>
+        <item>
+          <p>
+	    Add functions <c>application:set_env/1,2</c> and
+	    <c>application:set_env/2</c>. These take a list of
+	    application configuration parameters, and the behaviour
+	    is equivalent to calling <c>application:set_env/4</c>
+	    individually for each application/key combination, except
+	    it is more efficient.</p>
+          <p>
+	    <c>set_env/1,2</c> warns about duplicated applications or
+	    keys. The warning is also emitted during boot, if
+	    applications or keys are duplicated within one
+	    configuration file, e.g. sys.config.</p>
+          <p>

+        <item>
+          <p>
+	    Handler specific configuration parameters for the
+	    standard handler <c>logger_std_h</c> are changed to be
+	    more intuitive and more similar to the disk_log handler.</p>
+          <p>
+	    Earlier there was only one parameter, <c>type</c>, which
+	    could have the values <c>standard_io</c>,
+	    <c>standard_error</c>, <c>{file,FileName}</c> or
+	    <c>{file,FileName,Modes}</c>.</p>
+          <p>
+	    This is now changed, so the following parameters are
+	    allowed:</p>
+          <p>
+	    <c>type = standard_io | standard_error | file</c><br/>
+	    <c>file = file:filename()</c><br/> <c>modes =
+	    [file:mode()]</c></p>
+          <p>
+	    All parameters are optional. <c>type</c> defaults to
+	    <c>standard_io</c>, unless a file name is given, in which
+	    case it defaults to <c>file</c>. If <c>type</c> is set to
+	    <c>file</c>, the file name defaults to the same as the
+	    handler id.</p>
+          <p>
+	    The potential incompatibility is that
+	    <c>logger:get_config/0</c> and
+	    <c>logger:get_handler_config/1</c> now returns the new
+	    parameters, even if the configuration was set with the
+	    old variant, e.g. <c>#{type=>{file,FileName}}</c>.</p>
+          <p>
+	    *** POTENTIAL INCOMPATIBILITY ***</p>
+          <p>
+	    Own Id: OTP-15662</p>
+        </item>
+        <item>
+          <p>
+	    The new configuration parameter <c>file_check</c> is
+	    added to the Logger handler <c>logger_std_h</c>. This
+	    parameter specifies how long (in milliseconds) the
+	    handler may wait before checking if the log file still
+	    exists and the inode is the same as when it was opened.</p>
+          <p>
+	    The default value is 0, which means that this check is
+	    done prior to each write operation. Setting a higher
+	    number may improve performance, but adds the risk of
+	    loosing log events.</p>

+%%% 4. GET-NEXT REQUEST
+%%% --------------
+%%%   According to RFC1157, section 4.1.3 and RFC1905, section 4.2.2.
+%%%-----------------------------------------------------------------
+%%-----------------------------------------------------------------
+%% Func: do_get_next/3
+%% Purpose: do_get_next handles "getNextRequests".
+%% Note: Even if it is SNMPv1, a varbind's value can be
+%%       endOfMibView. This is converted to noSuchName in process_pdu.
+%% Returns: {noError, 0, ListOfNewVarbinds} |
+%%          {ErrorStatus, ErrorIndex, []}
+%% Note2: ListOfNewVarbinds is not sorted in any order!!!
+%% Alg: First, the variables are sorted in OID order.
+%%
+%%      Second, next in the MIB is performed for each OID, and
+%%      the result is collected as: if next oid is a variable,
+%%      perform a get to retrieve its value; if next oid is in a
+%%      table, save this value and continue until we get an oid
+%%      outside this table. Then perform get_next on the table,
+%%      and continue with all endOfTables and the oid outside the
+%%      table; if next oid is an subagent, save this value and
+%%      continue as in the table case.
+%%
+%%      Third, each response is checked for endOfMibView, or (for
+%%      subagents) that the Oid returned has the correct prefix.
+%%      (This is necessary since an SA can be registered under many
+%%      separated subtrees, and if the last variable in the first
+%%      subtree is requested in a next, the SA will return the first
+%%      variable in the second subtree. This might be working, since
+%%      there may be a variable in between these subtrees.) For each
+%%      of these, a new get-next is performed, one at a time.
+%%      This alg. might be optimised in several ways. The most 
+%%      striking one is that the same SA might be called several
+%%      times, when one time should be enough. But it isn't clear
+%%      that this really matters, since many nexts across the same
+%%      subagent must be considered to be very rare.

+	    When an SSH server receives the very first message on a
