Method delete_url: .Querydelete_url(string|Standards.URIurl, void|mapping(string:int|string|array(string)) query_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Querycon)
Description: Sends a HTTP DELETE request to the server in the URL and returns the created and initialized Query object. 0 is returned upon failure. If a query object having request_headers->Connection=="Keep-Alive" from a previous request is provided and the already established server connection can be used for the next request, you may gain some performance.

Method do_async_method: voiddo_async_method(stringmethod, string|Standards.URIurl, void|mapping(string:int|string|array(string)) query_variables, void|mapping(string:string|array(string)|int) request_headers, Protocols.HTTP.Querycon, void|stringdata)
Description: Low level asynchronous HTTP call method.
Parameter method: The HTTP method to use, e.g. "GET".
Parameter url: The URL to perform method on. Should be a complete URL, including protocol, e.g. "https://pike.lysator.liu.se/".
Parameter query_variables: Calls http_encode_query and appends the result to the URL.
Parameter request_headers: The HTTP headers to be added to the request. By default the headers User-agent, Host and, if needed by the url, Authorization will be added, with generated contents. Providing these headers will override the default. Setting the value to 0 will remove that header from the request.
Parameter con: Previously initialized connection object. In particular the callbacks must have been set (Query.set_callbacks()).
Parameter data: Data payload to be transmitted in the request.

Method get_url: .Queryget_url(string|Standards.URIurl, void|mapping(string:int|string|array(string)) query_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Querycon)
Description: Sends a HTTP GET request to the server in the URL and returns the created and initialized Query object. 0 is returned upon failure. If a query object having request_headers->Connection=="Keep-Alive" from a previous request is provided and the already established server connection can be used for the next request, you may gain some performance.

Method get_url_data: stringget_url_data(string|Standards.URIurl, void|mapping(string:int|string|array(string)) query_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Querycon)
Description: Returns the returned data after calling the requested server for information through HTTP GET. 0 is returned upon failure. Redirects (HTTP 302) are automatically followed.

Method get_url_nice: array(string)|zeroget_url_nice(string|Standards.URIurl, void|mapping(string:int|string|array(string)) query_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Querycon)
Description: Returns an array of ({content_type, data}) after calling the requested server for the information. 0 is returned upon failure. Redirects (HTTP 302) are automatically followed.

Method http_encode_query

stringhttp_encode_query(mapping(string:int|string|array(string)) variables)

Description

Encodes a query mapping to a string; this protects odd - in http perspective - characters like '&' and '#' and control characters, and packs the result together in a HTTP query string.

Example:

	> Protocols.HTTP.http_encode_query( (["anna":"eva","lilith":"blue"]) );
     Result: "lilith=blue&anna=eva"
     > Protocols.HTTP.http_encode_query( (["&amp;":"&","'=\"":"\0\0\0\u0434"]) );
     Result: "%27%3D%22=%00%00%00%D0%B4&%26amp%3B=%26"

Method iri_encode: stringiri_encode(strings)
Description: Encodes the given string using %XX encoding to be used as a component part in an IRI (Internationalized Resource Identifier, see RFC 3987). This means that all chars outside the IRI iunreserved set are encoded, i.e. this function encodes equivalently to uri_encode except that all 8-bit and wider characters are left as-is.
Bugs: This function currently does not encode chars in the Unicode private ranges, although that is strictly speaking required in some but not all IRI components. That could change if it turns out to be a problem.
See also: percent_decode, uri_encode

Method percent_decode: stringpercent_decode(strings)
Description: Decodes URI-style %XX encoded chars in the given string.
See also: percent_encode, uri_decode
Bugs: This function currently does not accept wide string input, which is necessary to work as the reverse of iri_encode.

Method percent_encode

stringpercent_encode(strings)

Description

Encodes the given string using %XX encoding, except that URI unreserved chars are not encoded. The unreserved chars are A-Z, a-z, 0-9, -, ., _, and ~ (see RFC 2396 section 2.3).

8-bit chars are encoded straight, and wider chars are not allowed. That means this encoding is applicable if s is a binary octet string. If it is a character string then uri_encode should be used instead.

It is also slightly faster than uri_encode if s is known to contain only US-ASCII.

Method post_url: .Querypost_url(string|Standards.URIurl, mapping(string:int|string|array(string))|stringquery_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Querycon)
Description: Similar to get_url, except that query variables is sent as a POST request instead of a GET request. If query_variables is a simple string, it is assumed to contain the verbatim body of the POST request; Content-Type must be properly specified manually, in this case.

Method post_url_data: stringpost_url_data(string|Standards.URIurl, mapping(string:int|string|array(string))|stringquery_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Querycon)
Description: Similar to get_url_data, except that query variables is sent as a POST request instead of a GET request.

Method post_url_nice: array(string) post_url_nice(string|Standards.URIurl, mapping(string:int|string|array(string))|stringquery_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Querycon)
Description: Similar to get_url_nice, except that query variables is sent as a POST request instead of a GET request.

Method put_url: .Queryput_url(string|Standards.URIurl, void|stringfile, void|mapping(string:int|string|array(string)) query_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Querycon)
Description: Sends a HTTP PUT request to the server in the URL and returns the created and initialized Query object. 0 is returned upon failure. If a query object having request_headers->Connection=="Keep-Alive" from a previous request is provided and the already established server connection can be used for the next request, you may gain some performance.

Method quoted_string_decode: stringquoted_string_decode(strings)
Description: Decodes the given string which has been encoded as a quoted-string according to RFC 2616 section 2.2. s is assumed to not include the surrounding " chars.
See also: quoted_string_encode

Method quoted_string_encode

stringquoted_string_encode(strings)

Description

Encodes the given string quoted to be used as content inside a quoted-string according to RFC 2616 section 2.2. The returned string does not include the surrounding " chars.

Note

The quoted-string quoting rules in RFC 2616 have several problems:

Quoting is inconsistent since " is quoted as \", but \ does not need to be quoted. This is resolved in the HTTP bis update to mandate quoting of \ too, which this function performs.
Many characters are not quoted sufficiently to make the result safe to use in an HTTP header, so this quoting is not enough if s contains NUL, CR, LF, or any 8-bit or wider character.

See also

quoted_string_decode

Method uri_decode: stringuri_decode(strings)
Description: Decodes URI-style %XX encoded chars in the given string, and then UTF-8 decodes the result. This is the reverse of uri_encode and uri_encode_invalids.
See also: uri_encode, uri_encode_invalids

Method uri_encode

stringuri_encode(strings)

Description

Encodes the given string using %XX encoding to be used as a component part in a URI. This means that all URI reserved and excluded characters are encoded, i.e. everything except A-Z, a-z, 0-9, -, ., _, and ~ (see RFC 2396 section 2.3).

8-bit chars and wider are encoded using UTF-8 followed by percent-encoding. This follows RFC 3986 section 2.5, the IRI-to-URI conversion method in the IRI standard (RFC 3987) and appendix B.2 in the HTML 4.01 standard. It should work regardless of the charset used in the XML document the URI might be inserted into.

See also

uri_decode, uri_encode_invalids, iri_encode

Method uri_encode_invalids

stringuri_encode_invalids(strings)

Description

Encodes all "dangerous" chars in the given string using %XX encoding, so that it can be included as a URI in an HTTP message or header field. This includes control chars, space and various delimiter chars except those in the URI reserved set (RFC 2396 section 2.2).

Since this function doesn't touch the URI reserved chars nor the escape char %, it can be used on a complete formatted URI or IRI.

8-bit chars and wider are encoded using UTF-8 followed by percent-encoding. This follows RFC 3986 section 2.5, the IRI standard (RFC 3987) and appendix B.2 in the HTML 4.01 standard.

Note

The characters in the URI reserved set are: :, /, ?, #, [, ], @, !, $, &, ', (, ), *, +, ,, ;, =. In addition, this function doesn't touch the escape char %.

Module Protocols.HTTP.Authentication

Description

This module contains various HTTP Authentication implementations for both server and client use. A Client implementation would typically call the make_authenticator method with the incoming WWW-Authenticate header to get a Client object. For each HTTP request the auth() method of the object can be called to get an appropriate Authorization header.

Server code should create an authentication class and inherit the concrete authentication scheme implementation. To add an actual user lookup, overload get_password or get_hashed_password. Hashed passwords must be hashed with the scheme appropriate digest.

Example

class Auth {
   inherit Protocols.HTTP.Authentication.DigestMD5Server;
   Concurrent.Future get_password(string user) {
     Promise p = Concurrent.Promise();
     if( user == "bob" )
       return p->success("builder");
     return p->failure(sprintf("No user %O", user));
   }
 }
 Auth auth = Auth("apps@pike.org");
 Concurrent.Future authenticate(Protocols.HTTP.Server.Request req) {
   Concurrent.Future authenticated = Concurrent.Promise();
   auth->auth(req->request_headers->authorization,
              req->request_method, request->not_query)
     ->then(lambda(string user) {
         authenticated->success(user);
       },
       lambda(string reason) {
         authenticated->failure(reason);
         string c = auth->challenge();
         request->response_and_finish( ([ "error":401,
                                          "extra_heads" : ([
                                            "WWW-Authenticate":c,
                                        ]) ]) );

The classes that typical users need to use are

: This is an object that attempts to behave as a Stdio.File as much as possible.
: This is an object that attempts to behave as a Stdio.Port as much as possible, with Port()->accept() returning File objects.
: The configurated context for the File.
: A class for keeping track of certificate chains and their private keys.

The Constants module also contains lots of constants that are used by the various APIs, as well as functions for formatting the constants for output.

It uses the send_packet() function to transmit packets.

Method send_renegotiate

voidsend_renegotiate()

Description

Renegotiate the connection (client initiated).

Sends a client_hello to force a new round of handshaking.

Class SSL.Connection

Description

SSL.Connection keeps the state relevant for a single SSL connection. This includes the Context object (which doesn't change), various buffers, the Session object (reused or created as appropriate), and pending read and write states being negotiated.

Each connection will have two sets of read and write States: The current read and write states used for encryption, and pending read and write states to be taken into use when the current keyexchange handshake is finished.

This object is also responsible for managing incoming and outgoing packets. Outgoing packets are stored in queue objects and sent in priority order.

Note

This class should never be created directly, instead one of the classes that inherits it should be used (ie either ClientConnection or ServerConnection) depending on whether this is to be a client-side or server-side connection. These in turn are typically created by File()->create().

Parameter data

String of data received from the peer.

Returns

Returns one of:

These are the main cases of errors: There was a low-level protocol communications failure (the data didn't look like an SSL packet), in which case the alert_callback will be called with the raw packet data. This can eg be used to detect HTTP clients connecting to an HTTPS server and similar. The peer has sent an `Alert` packet, and `handle_alert()` for it has returned -1. The peer has sent an unsupported/illegal sequence of packets, in which case a suitable `Alert` will have been generated and queued for sending to the peer.

Class SSL.Context

Description

Keeps the state that is shared by all SSL-connections on a client, or for one port on a server. It includes policy configuration, the server or client certificate(s), the corresponding private key(s), etc. It also includes the session cache.

The defaults are usually suitable for a client, but for a server some configuration is necessary.

Typical use is to:

Call add_cert() with the certificates belonging to the server or client. Note that clients often don't have or need any certificates, and also that certificate-less server operation is possible, albeit discouraged and not enabled by default.
Suitable self-signed certificates can be created with Standards.X509.make_selfsigned_certificate().
Optionally call get_suites() to get a set of cipher_suites to assign to preferred_suites. This is only needed if the default set of suites from get_suites(128, 1) isn't satisfactory.

The initialized Context object is then passed to File()->create() or used as is embedded in Port.

Description

Add a certificate.

This function is used on both servers and clients to add a key and chain of certificates to the set of certificate candidates to use in find_cert().

On a server these are used in the normal initial handshake, while on a client they are only used if a server requests client certificate authentication.

Parameter key

Private key matching the first certificate in certs.

Supported key types are currently:

`Crypto.RSA.State`	Rivest-Shamir-Adelman.
`Crypto.DSA.State`	Digital Signing Algorithm.
`Crypto.ECC.Curve.ECDSA`	Elliptic Curve Digital Signing Algorithm.

This key MUST match the public key in the first certificate in certs.

get_suites()

Method decode_ticket

Session|zerodecode_ticket(string(8bit)ticket)

Description

Decode a session ticket and return the corresponding session if valid or zero if invalid.

Note

The default implementation just calls lookup_session().

Override this function (and encode_ticket()) to implement server-side state-less session resumption.

See also

encode_ticket(), lookup_session()

Method encode_ticket

array(string(8bit)|int)|zeroencode_ticket(Sessionsession)

Description

Generate a session ticket for a session.

Note

The default implementation just generates a random ticket and calls record_session() to store it.

Over-ride this function (and decode_ticket()) to implement server-side state-less session resumption.

Returns

Array
`string(8bit)0`	Non-empty string with the ticket.
`int1`	Lifetime hint for the ticket.

Note

If the context signals that it does offer tickets via offers_tickets(), this function must offer an encoded ticket for the session as the connection may have signalled to the client that a ticket will be offered. However, tickets are not guaranteed to be actually usable, so if you cannot offer a ticket when you must, "INVALID" might be an option...

Method get_psk_hint: optionalstring(8bit)get_psk_hint()
Description: A context created for server side PSK use can optionally implement get_psk_hint to return a hint string to be sent to the client. If not implemented, or returning 0, no PSK hint will be sent.

Method get_psk_id

optionalstring(8bit)get_psk_id(string(8bit)hint)

Description

A context created for client side PSK use must implement a get_psk_id method, which will be called with the server provided hint, or 0 if no hint was sent. Note that while there is an API difference between no hint and a zero length hint, some PSK modes are unable to send no hints.

Array of authorities that are accepted for client certificates. The server will only accept connections from clients whose certificate is signed by one of these authorities. The string is a DER-encoded certificate, which typically must be decoded using MIME.decode_base64 or Standards.PEM.Messages first.

Note that it is presumed that the issuer will also be trusted by the server. See trusted_issuers for details on specifying trusted issuers.

If empty, the server will accept any client certificate whose issuer is trusted by the server.

Method set_trusted_issuers

voidset_trusted_issuers(array(array(string(8bit))) issuers)

Description

Sets the list of trusted certificate issuers.

Parameter issuers

An array of certificate chains whose root is self signed (ie a root issuer), and whose final certificate is an issuer that we trust. The root of the certificate should be first certificate in the chain. The string is a DER-encoded certificate, which typically must be decoded using MIME.decode_base64 or Standards.PEM.Messages first.

If this array is left empty, and the context is set to verify certificates, a certificate chain must have a root that is self signed.

Method sort_suites: array(int) sort_suites(array(int) suites)
Description: Sort a set of cipher suites according to our preferences.
Returns: Returns the array sorted with the most preferrable (aka "best") cipher suite first.
Note: The original array (suites) is modified destructively, but is not the same array as the result.

Class SSL.File

Description

Interface similar to Stdio.File.

Handles blocking and nonblocking mode.
Handles callback mode in an arbitrary backend (also in blocking mode).
Read and write operations may each do both reading and writing. In callback mode that means that installing either a read or a write callback may install both internally.
In Pike 8.0 and later, blocking read and write in concurrent threads is supported.
Callback changing operations like set_blocking and set_nonblocking aren't atomic.
Apart from the above, thread safety/atomicity characteristics are retained.
Blocking characterstics are retained for all functions.
is_open, connection init (create) and close (close) can do both reading and writing.
_destruct attempts to close the stream properly by sending the close packet, but since it can't do blocking I/O it's not certain that it will succeed. The stream should therefore always be closed with an explicit close call.
Abrupt remote close without the proper handshake gets the errno System.EPIPE.
Objects do not contain cyclic references, so they are closed and destructed timely when dropped.

Variable application_protocol: string SSL.File.application_protocol
Description: The application protocol chosen by the client during application layer protocol negotiation (ALPN).
Note: Read only

Variable fragment_max_size: protectedint SSL.File.fragment_max_size
Description: The max amount of data to send in each packet. Initialized from the context when the object is created.

Method _destruct: protectedvoid_destruct()
Description: Try to close down the connection properly since it's customary to close files just by dropping them. No guarantee can be made that the close packet gets sent successfully though, because we can't risk blocking I/O here. You should call close explicitly.
See also: close

Method accept: boolaccept(string|voidpending_data)
Description: Configure as server and set up the connection.
Parameter pending_data: Any data that has already been read from the stream. This is typically used with protocols that use START TLS or similar, where there's a risk that "too much" data (ie part of the TLS ClientHello) has been read from the stream before deciding that the connection is to enter TLS-mode.
Returns: Returns 0 on handshaking failure in blocking mode, and otherwise 1.
See also: connect()

Method backend_once: protectedint(0)|floatbackend_once(int|voidnonwaiting_mode)
Description: Run one pass of the backend.

Method close: intclose(void|stringhow, void|intclean_close, void|intdont_throw)
Description: Close the connection. Both the read and write ends are always closed
Parameter how: This argument is only for Stdio.File compatibility and must be either "rw" or 0.
Parameter clean_close: If set then close messages are exchanged to shut down the SSL connection but not the underlying stream. It may then continue to be used for other communication afterwards. The default is to send a close message and then close the stream without waiting for a response.
Parameter dont_throw: I/O errors are normally thrown, but that can be turned off with dont_throw. In that case errno is set instead and 0 is returned. 1 is always returned otherwise. It's not an error to close an already closed connection.
Note: If a clean close is requested in nonblocking mode then the stream is most likely not closed right away, and the backend is then still needed for a while afterwards to exchange the close packets. is_open returns 2 in that time window.
Note: I/O errors from both reading and writing might occur in blocking mode.
Note: If a clean close is requested and data following the close message is received at the same time, then this object will read it and has no way to undo that. That data can be retrieved with read afterwards.
See also: shutdown

Method connect: SSL.Session|zeroconnect(string|voiddest_addr, SSL.Session|voidsession)
Description: Configure as client and set up the connection.
Parameter dest_addr: Optional name of the server that we are connected to.
Parameter session: Session to resume (if any).
Returns: Returns 0 on handshaking failure in blocking mode, and otherwise the Session object for the connection.
Throws: Throws an error if a connection already has been established.
See also: accept()

Method create

The backend used by stream is taken over and restored after the connection is closed (see close and shutdown). The callbacks and id in stream are overwritten.

Note

The operation mode defaults to nonblocking mode.

intis_open()

Returns

Returns nonzero if the stream currently is open, zero otherwise.

This function does nonblocking I/O to check for a close packet in the input buffer.

Note

In Pike 7.8 and earlier, this function returned zero in the case above where it now returns 2.

Returns: Returns the current read callback.
See also: set_read_callback, set_nonblocking, query_callbacks

Method query_stream

Stdio.Filequery_stream()

Description

Return the underlying stream.

Note

Avoid any temptation to do destruct(file_obj->query_stream()). That almost certainly creates more problems than it solves.

You probably want to use shutdown.

shutdown

Method query_suite: intquery_suite()
Description: Return the currently active cipher suite.

Method query_timeout: int(0)|floatquery_timeout()
Description: Get the timeout for blocking operations.
See also: set_timeout()

Method read: stringread(void|intlength, void|boolnot_all)
Description: Read some (decrypted) data from the connection. Works like Stdio.File.read.
Note: I/O errors from both reading and writing might occur in blocking mode.
See also: write

Method renegotiate

intrenegotiate()

Description

Renegotiate the connection by starting a new handshake. Note that the accept callback will be called again when the handshake is finished.

Returns zero if there are any I/O errors. errno() will give the details.

Note

The read buffer is not cleared - a read() afterwards will return data from both before and after the renegotiation.

Bugs

Data in the write queue in nonblocking mode is not properly written before resetting the connection. Do a blocking write("") first to avoid problems with that.

Method schedule_poll: protectedvoidschedule_poll()
Description: Schedule calling of any relevant callbacks the next time the real_backend is run.
See also: internal_poll()

Method set_accept_callback

voidset_accept_callback(function(void|object, void|mixed:int)|zeroaccept)

Description

Install a function that will be called when the handshake is finished and the connection is ready for use.

The callback function will be called with the File object and the additional id arguments (set with set_id).

Note

Like the read, write and close callbacks, installing this callback implies callback mode, even after the handshake is done.

See also

set_nonblocking, set_callbacks, query_accept_callback, query_callbacks

Method set_alert_callback

voidset_alert_callback(function(object, int|object, string:void)|zeroalert)

Description

Install a function that will be called when an alert packet is about to be sent. It doesn't affect the callback mode - it's called both from backends and from within normal function calls like read and write.

This callback can be used to implement fallback to other protocols when used on the server side together with shutdown().

Note

This object is part of a cyclic reference whenever this is set, just like setting any other callback.

Note

This callback is not cleared by set_blocking, or settable by set_callbacks or set_nonblocking. It is also not part of the set returned by query_callbacks.

See also

query_alert_callback

Method set_backend: voidset_backend(Pike.Backendbackend)
Description: Set the backend used for the file callbacks.
See also: query_backend

Method set_blocking: voidset_blocking()
Description: Set the stream in blocking mode. All but the alert callback are zapped.
Note: There might be some data still waiting to be written to the stream. That will be written in the next blocking call, regardless what it is.
Note: This function doesn't solve the case when the connection is used nonblocking in some backend thread and another thread switches it to blocking and starts using it. To solve that, put a call out in the backend from the other thread that switches it to blocking, and then wait until that call out has run.
Note: Prior to version 7.5.12, this function didn't clear the accept callback.
See also: set_nonblocking, set_blocking_keep_callbacks, set_nonblocking_keep_callbacks

Method set_blocking_keep_callbacks: voidset_blocking_keep_callbacks()
Description: Set blocking mode like set_blocking, but don't alter any callbacks.
See also: set_blocking, set_nonblocking

Method set_buffer_mode

voidset_buffer_mode(Stdio.Buffer|int(0)in, Stdio.Buffer|int(0)out)

Description

Toggle the file to Buffer mode.

In this mode reading and writing will be done via Buffer objects, in the directions you included buffers.

Parameter in

Input buffer. If this buffer is non-empty, its contents will be returned after any already received data.

Parameter out

Output buffer. If this buffer is non-empty, its contents will be sent after any data already queued for sending.

See also

query_buffer_mode()

Method set_callbacks

Description

Installs all the specified callbacks at once. Use UNDEFINED to keep the current setting for a callback.

Like set_nonblocking, the callbacks are installed atomically. As opposed to set_nonblocking, this function does not do anything with the stream, and it doesn't even have to be open.

Bugs

read_oob and write_oob are currently ignored.

See also

set_read_callback, set_write_callback, set_close_callback, set_accept_callback, query_callbacks

Method set_close_callback: voidset_close_callback(function(void|mixed:int)|zeroclose)

Description: Set the stream in nonblocking mode, installing the specified callbacks. The alert callback isn't touched.
Note: Prior to version 7.5.12, this function didn't set the accept callback.
Bugs: read_oob and write_oob are currently ignored.
See also: set_callbacks, query_callbacks, set_nonblocking_keep_callbacks, set_blocking

Method set_nonblocking_keep_callbacks: voidset_nonblocking_keep_callbacks()

Description: Install a function to be called when data can be written.
See also: query_write_callback, set_nonblocking, query_callbacks

Method shutdown

Stdio.Fileshutdown()

Description

Shut down the SSL connection without sending any more packets.

If the connection is open then the underlying (still open) stream is returned.

If a nonclean (i.e. normal) close has been requested then the underlying stream is closed now if it wasn't closed already, and zero is returned.

If a clean close has been requested (see the second argument to close) then the behavior depends on the state of the close packet exchange: The first shutdown call after a successful exchange returns the (still open) underlying stream, and later calls return zero and clears errno. If the exchange hasn't finished then the stream is closed, zero is returned, and errno will return System.EPIPE.

See also

close, set_alert_callback

Method write: intwrite(string|array(string) data, mixed ... args)
Description: Write some (unencrypted) data to the connection. Works like Stdio.File.write except that this function often buffers some data internally, so there's no guarantee that all the consumed data has been successfully written to the stream in nonblocking mode. It keeps the internal buffering to a minimum, however.
Note: This function returns zero if attempts are made to write data during the handshake phase and the mode is nonblocking.
Note: I/O errors from both reading and writing might occur in blocking mode.

Class Protocols.DNS.async_client

Description: Asynchronous DNS client.

Inherit client: inherit client : client

Inherit udp: inherit Stdio.UDP : udp

Method close: voidclose()
Description: Close the client.
Note: All active requests are aborted.

Method create: Protocols.DNS.async_clientProtocols.DNS.async_client(void|string|array(string) server, void|string|array(string) domain)

Method do_query: Requestdo_query(stringdomain, intcl, inttype, function(string, mapping, __unknown__ ... :void) callback, mixed ... args)
Description: Enqueue a new raw DNS request.
Returns: Returns a Request object.
Note: Pike versions prior to 8.0 did not return the Request object.

Method generic_query

voidgeneric_query(stringtype, stringdomain, function(array(string)|zero, __unknown__ ... :void) callback, mixed ... restargs)

Description

Asynchronous DNS query with multiple results and a distinction between failure and empty results.

Parameter type

DNS query type. Currenlty supported:

`"A"`	Return just IPv4 records.
`"AAAA"`	Return both IPv6 and IPv4 records.
`"PTR"`	Reverse lookup for IP addresses, it expects normal IP addresses for `domain`.
`"TXT"`	Return TXT records.
`"MX"`	Return MX records sorted by `preference`, lowest numbers first.
`"MXIP"`	Like querying for `MX`, except it returns IP addresses instead of the MX records themselves.

Parameter domain

The domain name we are querying. Add a trailing dot to prohibit domain-postfix searching.

Parameter callback

The callback function that receives the result of the DNS query. It should be declared as follows: void callback(array(string)|zero results, mixed ... restargs); If the request fails it will return zero for results.

Parameter restargs

They are passed unaltered to the callback function.

Note

There is a notable difference between results equal to zero (= request failed and can be retried) and ({}) (= request definitively answered the record does not exist; retries are pointless).

Note

This method uses the exact same heuristics as the standard DNS resolver library (regarding the use of /etc/hosts, and when to perform a domain-postfix search, and when not to (i.e. trailing dot)).

Note

All queries sort automatically by preference (lowest numbers first).

Module Protocols.DNS_SD

Class Protocols.DNS_SD.Service

Description

This class provides an interface to DNS Service Discovery. The functionality of DNS-SD is described at <http://www.dns-sd.org/>.

Using the Proctocols.DNS_SD.Service class a Pike program can announce services, for example a web site or a database server, to computers on the local network.

When registering a service you need to provide the service name. service type, domain and port number. You can also optionally specify a TXT record. The contents of the TXT record varies between different services; for example, a web server can announce a path to a web page, and a printer spooler is able to list printer features such as color support or two-sided printing.

The service is registered on the network for as long as the instance of the Service class is valid.

Inherit Service: inherit _Protocols_DNS_SD.Service : Service

Method create

Protocols.DNS_SD.ServiceProtocols.DNS_SD.Service(stringname, stringservice, stringdomain, intport, void|string|array(string) txt)

Description

Registers a service on the local network.

Parameter name

User-presentable name of the service.

Parameter service

Type of service on the form _type._protocol. Type is an identifier related to the service type. A list of registered service types can be found at http://http://www.dns-sd.org/ServiceTypes.html/. Protocol is normally tcp but udp is also a valid choice. For example, a web server would get a service of _http._tcp.

Parameter domain

Domain name. Normally an empty string which the DNS-SD library will translate into local..

Parameter port

Port number for the service (e.g. 80 for a web site).

Parameter txt

An optional TXT record with service-specific information. It can be given as a plain string or an array of property assignment strings. The TXT record can be changed later by calling update_txt in the object returned when you register the service.

Example

object svc = Protocols.DNS_SD.Service(
                 "Company Intranet Forum",  //  name
                 "_http._tcp",              //  service type
                 "",                        //  domain (default)
                 80,                        //  port
                 ({ "path=/forum/" })       //  TXT record
               );

Method update_txt: voidupdate_txt(string|array(string) txt)
Description: Updates the TXT record for the service.
Parameter txt: A TXT record with service-specific information. It can be given as a plain string or an array of property assignment strings. To remove an existing TXT record you give an empty string as the argument.

Constant SEARCH_LOWER_ATTRS

Constant SEARCH_RETURN_DECODE_ERRORS

constantint Protocols.LDAP.SEARCH_LOWER_ATTRS
constantint Protocols.LDAP.SEARCH_MULTIVAL_ARRAYS_ONLY
constantint Protocols.LDAP.SEARCH_RETURN_DECODE_ERRORS

Description

Bitfield flags given to Protocols.LDAP.client.search:

SEARCH_LOWER_ATTRS

Lowercase all attribute values. This makes it easier to match specific attributes in the mappings returned by Protocols.LDAP.client.result.fetch since LDAP attribute names are case insensitive.

SEARCH_MULTIVAL_ARRAYS_ONLY

Only use arrays for attribute values where the attribute syntax specify multiple values. I.e. the values for single valued attributes are returned as strings instead of arrays containing one string element.

If no value is returned for a single valued attribute, e.g. when attrsonly is set in the search call, then a zero will be used as value.

The special "dn" value is also returned as a string when this flag is set.

Note that it's the attribute type descriptions that are used to decide this, not the number of values a particular attribute happens to have in the search result.

SEARCH_RETURN_DECODE_ERRORS

Don't throw attribute value decode errors, instead return them in the result from Protocols.LDAP.client.result.fetch in place of the value. I.e. anywhere an attribute value string occurs, you might instead have a Charset.DecodeError object.

Description: Mapping from LDAP_* result codes to descriptive strings.

Constant syntax_decode_fns

constantmapping(string:function(string:string)) Protocols.LDAP.syntax_decode_fns

Description

Mapping containing functions to decode charsets in syntaxes where that's necessary. If the syntax is complex in a way that makes the result ambiguous if decoded with a single charset transformation then it should typically not be decoded here.

These decoders are used on all attribute values returned by Protocols.LDAP.client.result functions.

Constant syntax_encode_fns: constantmapping(string:function(string:string)) Protocols.LDAP.syntax_encode_fns
Description: Mapping containing the reverse functions from syntax_decode_fns.

Method canonicalize_dn

stringcanonicalize_dn(stringdn, void|intstrict)

Description

Returns the given distinguished name on a canonical form, so it reliably can be used in comparisons for equality. This means removing surplus whitespace, lowercasing attributes, normalizing quoting in string attribute values, lowercasing the hex digits in binary attribute values, and sorting the RDN parts separated by "+".

The returned string follows RFC 2253. The input string may use legacy LDAPv2 syntax and is treated according to RFC 2253 section 4.

If strict is set then errors will be thrown if the given DN is syntactically invalid. Otherwise the invalid parts remain untouched in the result.

Note

The result is not entirely canonical since no conversion is done from or to hexadecimal BER encodings of the attribute values. It's assumed that the input already has the suitable value encoding depending on the attribute type.

Note

No UTF-8 encoding or decoding is done. The function can be used on both encoded and decoded input strings, and the result will be likewise encoded or decoded.

Method encode_dn_value

stringencode_dn_value(stringstr)

Description

Encode the given string for use as an attribute value in a distinguished name (on string form).

The encoding is according to RFC 2253 section 2.4 with the exception that characters above 0x7F aren't UTF-8 encoded. UTF-8 encoding can always be done afterwards on the complete DN, which also is done internally by the Protocols.LDAP functions when LDAPv3 is used.

Method get_cached_filter: objectget_cached_filter(stringfilter, void|intldap_version)
Description: Like make_filter but saves the generated objects for reuse. Useful for filters that reasonably will occur often. The cache is never garbage collected, however.
Throws: If there's a parse error in the filter then a FilterError is thrown as from make_filter.

Method get_connection

objectget_connection(stringldap_url, void|stringbinddn, void|stringpassword, void|intversion, void|SSL.Contextctx)

Description

Returns a client connection to the specified LDAP URL. If a bind DN is specified (either through a "bindname" extension in ldap_url or, if there isn't one, through binddn) then the connection will be bound using that DN and the optional password. If no bind DN is given then any connection is returned, regardless of the bind DN it is using.

version may be used to specify the required protocol version in the bind operation. If zero or left out, a bind attempt with the default version (currently 3) is done with a fallback to 2 if that fails. Also, a cached connection for any version might be returned if version isn't specified.

ctx may be specified to control SSL/TLS parameters to use with the "ldaps"-protocol. Note that changing this only affects new connections.

As opposed to creating an Protocols.LDAP.client instance directly, this function can return an already established connection for the same URL, provided connections are given back using return_connection when they aren't used anymore.

A client object with an error condition is returned if there's a bind error, e.g. invalid password.

Method get_constant_name: stringget_constant_name(mixedval)
Description: If val matches any non-integer constant in this module, its name is returned.

Method ldap_decode_string: stringldap_decode_string(stringstr)
Description: Decodes all \xx escapes in str.
See also: ldap_encode_string

Method ldap_encode_string

stringldap_encode_string(stringstr)

Description

Quote characters in the given string as necessary for use as a string literal in filters and various composite LDAP attributes.

The quoting is compliant with RFC 2252 section 4.3 and RFC 2254 section 4. All characters that can be special in those RFCs are quoted using the \xx syntax, but the set might be extended.

ldap_decode_string, Protocols.LDAP.client.search

Method make_filter

objectmake_filter(stringfilter, void|intldap_version)

Description

Parses an LDAP filter string into an ASN1 object tree that can be given to Protocols.LDAP.search.

Using this function instead of giving the filter string directly to the search function has two advantages: This function provides better error reports for syntax errors, and the same object tree can be used repeatedly to avoid reparsing the filter string.

Parameter filter

The filter to parse, according to the syntax specified in RFC 2254. The syntax is extended a bit to allow and ignore whitespace everywhere except inside and next to the filter values.

Parameter ldap_version

LDAP protocol version to make the filter for. This controls what syntaxes are allowed depending on the protocol version. Also, if the protocol is 3 or later then full Unicode string literals are supported. The default is the latest supported version.

Returns

An ASN1 object tree representing the filter.

Throws

FilterError is thrown if there's a syntax error in the filter.

Method num_connections: intnum_connections(stringldap_url)
Description: Returns the number of currently stored connections for the given LDAP URL.

Method parse_ldap_url

mapping(string:mixed) parse_ldap_url(stringldap_url)

Description

Parses an LDAP URL and returns its fields in a mapping.

Returns

The returned mapping contains these fields:

`scheme : string`	The URL scheme, either `"ldap"` or `"ldaps"`.
`host : string`	Self-explanatory.
`port : int`
`basedn : string`
`attributes : array(string)`	Array containing the attributes. Undefined if none was specified.
`scope : int`	The scope as one of the `SEARCH_*` constants. Undefined if none was specified.
`filter : string`	The search filter. Undefined if none was specified.
`ext : mapping(string:string\|int(1))`	The extensions. Undefined if none was specified. The mapping values are `1` for extensions without values. Critical extensions are checked and the leading `"!"` do not remain in the mapping indices.
`url : string`	The original unparsed URL.

get_parsed_url

Method return_connection: voidreturn_connection(objectconn)
Description: Use this to return a connection to the connection pool after you've finished using it. The connection is assumed to be working.
Note: Ensure that persistent connection settings such as the scope and the base DN are restored to the defaults

Class Protocols.LDAP.FilterError

Description: Error object thrown by make_filter for parse errors.

Constant is_ldap_filter_error: constantint Protocols.LDAP.FilterError.is_ldap_filter_error
Description: Recognition constant.

Class Protocols.LDAP.client

Description: Contains the client implementation of the LDAP protocol. All of the version 2 protocol features are implemented but only the base parts of the version 3.

Inherit protocol: inherit .protocol : protocol

Variable info: mapping Protocols.LDAP.client.info
Description: Several information about code itself and about active connection too

Method add: intadd(stringdn, mapping(string:array(string)) attrs)
Description: The Add Operation allows a client to request the addition of an entry into the directory
Parameter dn: The Distinguished Name of the entry to be added.
Parameter attrs: The mapping of attributes and their values that make up the content of the entry being added. Values that are sent UTF-8 encoded according the the attribute syntaxes are encoded automatically.
Returns: Returns 1 on success, 0 otherwise.
Note: The API change: the returning code was changed in Pike 7.3+ to follow his logic better.

Method bind

intbind()
intbind(stringdn, stringpassword)
intbind(stringdn, stringpassword, intversion)

Description

Authenticates connection to the direcory.

First form uses default value previously entered in create.

Second form uses value from parameters:

Parameter dn

The distinguished name (DN) of an entry aginst which will be made authentication.

Parameter password

Password used for authentication.

Third form allows specify the version of LDAP protocol used by connection to the LDAP server.

Parameter version

The desired protocol version (current 2 or 3). Defaults to 3 if zero or left out.

Returns

Returns 1 on success, 0 otherwise.

Note

Only simple authentication type is implemented. So be warned clear text passwords are sent to the directory server.

Note

The API change: the returning code was changed in Pike 7.3+ to follow his logic better.

Method compare: intcompare(stringdn, stringattr, stringvalue)
Description: Compares an attribute value with one in the directory.
Parameter dn: The distinguished name of the entry.
Parameter attr: The type (aka name) of the attribute to compare.
Parameter value: The value to compare with. It's UTF-8 encoded automatically if the attribute syntax specifies that.
Returns: Returns 1 if at least one of the values for the attribute in the directory is equal to value, 0 if it didn't match or there was some error (use error_number to find out).
Note: This function has changed arguments since version 7.6. From 7.3 to 7.6 it was effectively useless since it always returned true.
Note: The equality matching rule for the attribute governs the comparison. There are attributes where the assertion syntax used here isn't the same as the attribute value syntax.

Method create: Protocols.LDAP.clientProtocols.LDAP.client()
Protocols.LDAP.clientProtocols.LDAP.client(string|mapping(string:mixed) url)
Protocols.LDAP.clientProtocols.LDAP.client(string|mapping(string:mixed) url, objectcontext)
Description: Create object. The first optional argument can be used later for subsequence operations. The second one can specify TLS context of connection. The default context only allows 128-bit encryption methods, so you may need to provide your own context if your LDAP server supports only export encryption.
Parameter url: LDAP server URL on the form "ldap://hostname/basedn?attrlist?scope?ext". See RFC 2255. It can also be a mapping as returned by Protocol.LDAP.parse_ldap_url.
Parameter context: TLS context of connection
See also: LDAP.client.bind, LDAP.client.search

Method delete: intdelete(stringdn)
Description: Deletes entry from the LDAP server.
Parameter dn: The distinguished name of deleted entry.
Returns: Returns 1 on success, 0 otherwise.
Note: The API change: the returning code was changed in Pike 7.3+ to follow his logic better.

Method get_attr_type_descr

mapping(string:mixed)|zeroget_attr_type_descr(stringattr, void|intstandard_attrs)

Description

Returns the attribute type description for the given attribute, which includes the name, object identifier, syntax, etc (see RFC 2252 section 4.2 for details).

This might do a query to the server, but results are cached.

Parameter attr

The name of the attribute. Might also be the object identifier on string form.

Parameter standard_attrs

Flag that controls how the known standard attributes stored in Protocols.LDAP are to be used:

`0`	Check the known standard attributes first. If the attribute isn't found there, query the server. This is the default.
`1`	Don't check the known standard attributes, i.e. always use the schema from the server.
`2`	Only check the known standard attributes. The server is never contacted.

Returns

Returns a mapping where the indices are the terms that the server has returned and the values are their values on string form (dequoted and converted from UTF-8 as appropriate). Terms without values get 1 as value in the mapping.

The mapping might contain the following members (all except "oid" are optional):

"oid" : string

The object identifier on string form. According to the RFC, this should always be a dotted decimal string. However some LDAP servers, e.g. iPlanet, allows registering attributes without an assigned OID. In such cases this can be some other string. In the case of iPlanet, it uses the attribute name with "-oid" appended (c.f. http://docs.sun.com/source/816-5606-10/scmacfg.htm).

"NAME" : string

Array with one or more names used for the attribute.

"DESC" : string

Description.

"OBSOLETE" : string

Flag.

"SUP" : string

Derived from this other attribute. The value is the name or oid of it. Note that the attribute description from the referenced type always is merged with the current one to make the returned description complete.

"EQUALITY" : string

The value is the name or oid of a matching rule.

"ORDERING" : string

The value is the name or oid of a matching rule.

"SUBSTR" : string

The value is the name or oid of a matching rule.

"syntax_oid" : string

The value is the oid of the syntax (RFC 2252 section 4.3.2). (This is extracted from the "SYNTAX" term.)

"syntax_len" : string

Optional suggested minimum upper bound of the number of characters in the attribute (or bytes if the attribute is binary). (This is extracted from the "SYNTAX" term.)

"SINGLE-VALUE" : string

Flag. Default multi-valued.

"COLLECTIVE" : string

Flag. Default not collective.

"NO-USER-MODIFICATION" : string

Flag. Default user modifiable.

"USAGE" : string

The value is any of the following:

`"userApplications"`	Self-explanatory.
`"directoryOperation"`	Self-explanatory.
`"distributedOperation"`	DSA-shared.
`"dSAOperation"`	DSA-specific, value depends on server.

There might be more fields for server extensions.

Zero is returned if the server didn't provide any attribute type description for attr.

Note

It's the schema applicable at the base DN that is queried.

Note

LDAPv3 is assumed.

Method get_basedn: stringget_basedn()
Description: Returns the current base DN for searches using search and schema queries using get_attr_type_descr.

Method get_bind_password_hash: string|zeroget_bind_password_hash()
Description: Returns an MD5 hash of the password used for the bind operation, or zero if the connection isn't bound. If no password was given to bind then an empty string was sent as password, and the MD5 hash of that is therefore returned.

Method get_bound_dn: stringget_bound_dn()
Description: Returns the bind DN currently in use for the connection. Zero is returned if the connection isn't bound. The empty string is returned if the connection is in use but no bind DN has been given explicitly to bind.

Method get_cached_filter: objectget_cached_filter(stringfilter)
Description: This is a wrapper for Protocols.LDAP.get_cached_filter which passes the LDAP protocol version currently in use by this connection.
Throws: If there's a parse error in the filter then a Protocols.LDAP.FilterError is thrown as from Protocols.LDAP.make_filter.

Method get_default_filter: object|zeroget_default_filter()
Description: Returns the ASN1 object parsed from the filter specified in the LDAP URL, or zero if the URL doesn't specify any filter.
Throws: If there's a parse error in the filter then a Protocols.LDAP.FilterError is thrown as from Protocols.LDAP.make_filter.

Method get_option: intget_option(intopttype)
Parameter option_type: LDAP_OPT_xxx

Method get_parsed_url: mapping(string:mixed) get_parsed_url()
Description: Returns a mapping containing the data parsed from the LDAP URL passed to create. The mapping has the same format as the return value from Protocols.LDAP.parse_ldap_url. Don't be destructive on the returned value.

Method get_protocol_version: intget_protocol_version()
Description: Return the LDAP protocol version in use.

Method get_referrals: array|intget_referrals()
Description: Gets referrals.

array(string) get_root_dse_attr(stringattr)

Description

Returns the value of an attribute in the root DSE (DSA-Specific Entry) of the bound server. The result is cached. A working connection is assumed.

Returns

The return value is an array of the attribute values, which have been UTF-8 decoded where appropriate.

Don't be destructive on the returned array.

Note

This function intentionally does not try to simplify the return values for single-valued attributes (c.f. Protocols.LDAP.SEARCH_MULTIVAL_ARRAYS_ONLY). That since (at least) Microsoft AD has a bunch of attributes in the root DSE that they don't bother to provide schema entries for. The return value format wouldn't be reliable if they suddenly change that.

Method get_scope: stringget_scope()
Description: Return the currently set scope as a string "base", "one", or "sub".

Method get_supported_controls: multiset(string) get_supported_controls()
Description: Returns a multiset containing the controls supported by the server. They are returned as object identifiers on string form. A working connection is assumed.

Description: Returns the ASN1 object parsed from the given filter. This is a wrapper for Protocols.LDAP.make_filter which parses the filter with the LDAP protocol version currently in use by this connection.
Throws: If there's a parse error in the filter then a Protocols.LDAP.FilterError is thrown as from Protocols.LDAP.make_filter.

Method modify

intmodify(stringdn, mapping(string:array(int(0..2)|string)) attropval)

Description

The Modify Operation allows a client to request that a modification of an entry be performed on its behalf by a server.

Parameter dn

The distinguished name of modified entry.

Parameter attropval

The mapping of attributes with requested operation and attribute's values.

attropval=([ attribute:({operation, value1, value2, ...})])

Where operation is one of the following:

Protocols.LDAP.MODIFY_ADD: Add values listed to the given attribute, creating the attribute if necessary.
Protocols.LDAP.MODIFY_DELETE: Delete values listed from the given attribute, removing the entire attribute if no values are listed, or if all current values of the attribute are listed for deletion.
Protocols.LDAP.MODIFY_REPLACE: Replace all existing values of the given attribute with the new values listed, creating the attribute if it did not already exist. A replace with no value will delete the entire attribute if it exists, and is ignored if the attribute does not exist.

Values that are sent UTF-8 encoded according the the attribute syntaxes are encoded automatically.

Returns

Returns 1 on success, 0 otherwise.

Note

The API change: the returning code was changed in Pike 7.3+ to follow his logic better.

Method modifydn: intmodifydn(stringdn, stringnewrdn, intdeleteoldrdn, string|voidnewsuperior)

Parameter dn: DN of source object
Parameter newrdn: RDN of destination
Parameter deleteoldrdn: The parameter controls whether the old RDN attribute values are to be retained as attributes of the entry, or deleted from the entry.
Parameter newsuperior: If present, this is the Distinguished Name of the entry which becomes the immediate superior of the existing entry.
Returns: Returns 1 on success, 0 otherwise.
Note: The API change: the returning code was changed in Pike 7.3+ to follow his logic better.

Returns

Returns a mapping of the requested attributes. It has the same form as the response from result.fetch.

See also

search

Method read_attr

Description

Reads a specified attribute of a specified object in the LDAP server. object_name is the distinguished name of the object and attr is the attribute. The rest of the arguments are the same as to search.

The default filter that might have been set in the LDAP URL doesn't affect this call. If filter isn't set then "(objectClass=*)" is used.

Returns

For single-valued attributes, the value is returned as a string. For multivalued attributes, the value is returned as an array of strings. Returns zero if there was an error.

Parameter attrs

The array of attribute names which will be returned by server for every entry.

Parameter attrsonly

This flag causes server return only the attribute types (aka names) but not their values. The values will instead be empty arrays or - if Protocols.LDAP.SEARCH_MULTIVAL_ARRAYS_ONLY is given - zeroes for single-valued attributes.

Parameter controls

Extra controls to send in the search query, to modify how the server executes the search in various ways. The value is a mapping with an entry for each control.

object_identifier : string

The index is the object identifier in string form for the control type. There are constants in Protocols.LDAP for the object identifiers for some known controls.

The mapping value is an array of two elements:

Array
`int0`	The first element is an integer flag that specifies whether the control is critical or not. If it is nonzero, the server returns an error if it doesn't understand the control. If it is zero, the server ignores it instead.
`string\|int(0)1`	The second element is the string value to pass with the control. It may also be zero to not pass any value at all.

Parameter flags

Bitfield with flags to control various behavior at the client side of the search operation. See the Protocol.LDAP.SEARCH_* constants for details.

Returns

Returns object LDAP.client.result on success, 0 otherwise.

Note

The API change: the returning code was changed in Pike 7.3+ to follow his logic better.

Returns

The return value is a mapping describing the entry:

attribute : string

An attribute in the entry. The value is an array containing the returned attribute value(s) on string form, or a single string if Protocols.LDAP.SEARCH_MULTIVAL_ARRAYS_ONLY was given to search and the attribute is typed as single valued.

If Protocols.LDAP.SEARCH_RETURN_DECODE_ERRORS was given to search then Charset.DecodeError objects are returned in place of a string whenever an attribute value fails to be decoded.

"dn" : string

This special entry contains the object name of the entry as a distinguished name.

This might also be a Charset.DecodeError if Protocols.LDAP.SEARCH_RETURN_DECODE_ERRORS was given to search.

Zero is returned if the cursor is outside the valid range of entries.

Throws

Unless Protocols.LDAP.SEARCH_RETURN_DECODE_ERRORS was given to search, a Charset.DecodeError is thrown if there is an error decoding the DN or any attribute value.

Note

It's undefined whether or not destructive operations on the returned mapping will affect future fetch calls for the same entry.

Parameter port

Port this server listen on

Parameter listenip

IP on which server listen

Parameter cb_mailfrom

Mailfrom callback function, this function will be called when a client send a mail from command. This function must take a string as argument (corresponding to the sender's email) and return int corresponding to the SMTP code to output to the client. If you return an array the first element is the SMTP code and the second is the error string to display.

Parameter cb_rcptto

Same as cb_mailfrom but called when a client sends a rcpt to.

Parameter cb_data

This function is called for each recipient in the "rcpt to" command after the client sends the "data" command It must have the following synopsis: int|array cb_data(object mime, string sender, string recipient, void|string rawdata) object mime : the mime data object string sender : sender of the mail (from the mailfrom command) string recipient : one recipient given by one rcpt command. return : SMTP code to output to the client. If you return an array the first element is the SMTP code and the second is the error string to display. Note that to comply with LMTP protocol you must output a code each time this function is called.

Module Protocols.XMLRPC

Description

This module implements most features of the XML-RPC standard (see http://xml-rpc.org/).

Translation rules for conversions from Pike datatypes to XML-RPC datatypes:

Pike int is translated to XML-RPC <int>. Pike string is translated to XML-RPC <string>. Pike float is translated to XML-RPC <double>. Pike mapping is translated to XML-RPC <struct>. Pike array is translated to XML-RPC <array>. Pike Calendar object is translated to XML-RPC <dateTime.iso8601. Pike Val.false and Val.true is translated to XML-RPC <boolean>.

Translation rules for conversions from XML-RPC datatypes to Pike datatypes:

XML-RPC <i4> and <int> are translated to Pike int. XML-RPC <boolean> is translated to Pike Val.true and Val.false. XML-RPC <string> and <base64> are translated to Pike string. XML_RPC <double> is translated to Pike float. XML-RPC <struct> is translated to Pike mapping. XML-RPC <array> is translated to Pike array. XML-RPC <dateTime.iso8601> is translated to Pike Calendar object.

Note

The XML-RPC <dateTime.iso8601> datatype does not assume any time zone, but local time is always used in the conversion to Calendar objects.
