Method get_url

.Query get_url(string|Standards.URI url, void|mapping(string:int|string|array(string)) query_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Query con)

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 http_encode_query

string http_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( (["&":"&","'=\"":"\0\0\0\u0434"]) );
     Result: "%27%3D%22=%00%00%00%D0%B4&%26amp%3B=%26"
	


Method iri_encode

string iri_encode(string s)

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

string percent_decode(string s)

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

string percent_encode(string s)

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

.Query post_url(string|Standards.URI url, mapping(string:int|string|array(string))|string query_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Query con)

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

string post_url_data(string|Standards.URI url, mapping(string:int|string|array(string))|string query_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Query con)

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.URI url, mapping(string:int|string|array(string))|string query_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Query con)

Description

Similar to get_url_nice, except that query variables is sent as a POST request instead of a GET request.


Method put_url

.Query put_url(string|Standards.URI url, void|string file, void|mapping(string:int|string|array(string)) query_variables, void|mapping(string:string|array(string)|int) request_headers, void|Protocols.HTTP.Query con)

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

string quoted_string_decode(string s)

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

string quoted_string_encode(string s)

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

string uri_decode(string s)

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

string uri_encode(string s)

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

string uri_encode_invalids(string s)

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, ]) ]) ); }); return authenticated; }

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().

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.

Method decode_ticket

Session|zero decode_ticket(string(8bit) ticket)

Description

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

Note

See also

encode_ticket(), lookup_session()


Method encode_ticket

array(string(8bit)|int)|zero encode_ticket(Session session)

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.

int 1

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...

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

void set_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

protected int 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

protected void _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

bool accept(string|void pending_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

protected int(0)|float backend_once(int|void nonwaiting_mode)

Description

Run one pass of the backend.


Method close

int close(void|string how, void|int clean_close, void|int dont_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|zero connect(string|void dest_addr, SSL.Session|void session)

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

Method create

SSL.File SSL.File(Stdio.File stream, SSL.Context ctx)

Description

Create an SSL connection over an open stream.

Parameter stream

Open socket or pipe to create the connection over.

Parameter ctx

The SSL context.

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.

See also

accept(), connect()


Method errno

Method is_open

int is_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.

If a clean close has been requested in nonblocking mode, then 2 is returned until the close packet exchanged has been completed.

Note

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

See also

set_read_callback, set_nonblocking, query_callbacks


Method query_stream

Stdio.File query_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.

See also

shutdown


Method query_suite

int query_suite()

Description

Return the currently active cipher suite.


Method query_timeout

int(0)|float query_timeout()

Description

Get the timeout for blocking operations.

Method read

string read(void|int length, void|bool not_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

int renegotiate()

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

protected void schedule_poll()

Description

Schedule calling of any relevant callbacks the next time the real_backend is run.

See also

internal_poll()


Method set_accept_callback

void set_accept_callback(function(void|object, void|mixed:int)|zero accept)

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

void set_alert_callback(function(object, int|object, string:void)|zero alert)

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

void set_backend(Pike.Backend backend)

Description

Set the backend used for the file callbacks.

See also

query_backend


Method set_blocking

void set_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

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

void set_callbacks(void|Stdio.read_callback_t read, void|Stdio.write_callback_t write, void|function(mixed:int) close, void|function(mixed, string:int) read_oob, void|function(mixed:int) write_oob, void|function(void|mixed:int) accept)

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

void set_close_callback(function(void|mixed:int)|zero close)

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

void set_nonblocking_keep_callbacks()

Description

Method set_write_callback

void set_write_callback(Stdio.write_callback_t|zero write)

Description

Install a function to be called when data can be written.

See also

query_write_callback, set_nonblocking, query_callbacks


Method shutdown

Stdio.File shutdown()

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

int write(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.

Method close

void close()

Description

Close the client.

Note

All active requests are aborted.


Method create

Protocols.DNS.async_client Protocols.DNS.async_client(void|string|array(string) server, void|string|array(string) domain)


Method do_query

Request do_query(string domain, int cl, int type, 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

void generic_query(string type, string domain, 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).

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

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

void update_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_RETURN_DECODE_ERRORS

constant int Protocols.LDAP.SEARCH_LOWER_ATTRS
constant int Protocols.LDAP.SEARCH_MULTIVAL_ARRAYS_ONLY
constant int 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.

constant string Protocols.LDAP.SYNTAX_TELETEX_TERMINAL_ID
constant string Protocols.LDAP.SYNTAX_TELETEX_NUM
constant string Protocols.LDAP.SYNTAX_SUPPORTED_ALGORITHM

Description

LDAP syntax: Standard syntaxes from RFC 2256.


Constant ldap_error_strings

constant Protocols.LDAP.ldap_error_strings

Description

Mapping from LDAP_* result codes to descriptive strings.


Constant syntax_decode_fns

constant mapping(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

constant mapping(string:function(string:string)) Protocols.LDAP.syntax_encode_fns

Description

Mapping containing the reverse functions from syntax_decode_fns.


Method canonicalize_dn

string canonicalize_dn(string dn, void|int strict)

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

string encode_dn_value(string str)

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

object get_cached_filter(string filter, void|int ldap_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

object get_connection(string ldap_url, void|string binddn, void|string password, void|int version, void|SSL.Context ctx)

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

string get_constant_name(mixed val)

Description

If val matches any non-integer constant in this module, its name is returned.


Method ldap_decode_string

string ldap_decode_string(string str)

Description

Decodes all \xx escapes in str.

See also

ldap_encode_string


Method ldap_encode_string

string ldap_encode_string(string str)

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.

See also

ldap_decode_string, Protocols.LDAP.client.search


Method make_filter

object make_filter(string filter, void|int ldap_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

int num_connections(string ldap_url)

Description

Returns the number of currently stored connections for the given LDAP URL.


Method parse_ldap_url

mapping(string:mixed) parse_ldap_url(string ldap_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.

See also

get_parsed_url


Method return_connection

void return_connection(object conn)

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

constant int 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

int add(string dn, 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

int bind()
int bind(string dn, string password)
int bind(string dn, string password, int version)

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

int compare(string dn, string attr, string value)

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.client Protocols.LDAP.client()
Protocols.LDAP.client Protocols.LDAP.client(string|mapping(string:mixed) url)
Protocols.LDAP.client Protocols.LDAP.client(string|mapping(string:mixed) url, object context)

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

int delete(string dn)

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)|zero get_attr_type_descr(string attr, void|int standard_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"
"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

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

object get_cached_filter(string filter)

Description

This is a wrapper for Protocols.LDAP.get_cached_filter which passes the LDAP protocol version currently in use by this connection.

Method get_default_filter

object|zero get_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.

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.

Search filter to override the one from the LDAP URL. It's either a string with the format specified in RFC 2254, or an object returned by Protocols.LDAP.make_filter.

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.

The mapping value is an array of two elements:

Array
int 0

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.

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

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.


Method decode_call

Call decode_call(string xml_input)

Description

Decodes a XML-RPC representation of a function call and returns a Call object.

Method encode_call

string encode_call(string method_name, array params)

Description

Encodes a function call with the name method_name and the arguments params and returns the XML-RPC string representation.


Method encode_response

string encode_response(array params)

Description

Encodes a response containing the multiple values in params and returns the XML-RPC string representation.


Method encode_response_fault

string encode_response_fault(int fault_code, string fault_string)

Description

Encodes a response fault containing a fault_code and a fault_string and returns the XML-RPC string representation.

Class Protocols.XMLRPC.AsyncClient

Description

This class implements an XML-RPC client that uses HTTP transport using non blocking sockets.

There is an optional boolean flag to get the new behavior of booleans being returned Val instead of ints.

Example

void data_ok(mixed result)
{
  write("result=%O\n", result);
}

void fail()
{
  write("fail\n");
}

int main(int argc, array argv)
{
  object async_client = Protocols.XMLRPC.AsyncClient("http://www.oreillynet.com/meerkat/xml-rpc/server.php");
  async_client["system.listMethods"](data_ok, fail);
  return -1;

Class Protocols.XMLRPC.Call

Description

Represents a function call made to a XML-RPC server.

decode_call()


Variable method_name

int Protocols.XMLRPC.Call.method_name

Description

Represents <methodName> in the XML-RPC standard.


Variable params

array Protocols.XMLRPC.Call.params

Description

Represents <params> in the XML-RPC standard where all datatypes have been converted to equivalent or similar datatypes in Pike.


Method __create__

Class Protocols.XMLRPC.Client

Description

This class implements an XML-RPC client that uses HTTP transport.

There is an optional boolean flag to get the new behavior of booleans being returned as Val instead of ints.

Example

   > Protocols.XMLRPC.Client client = Protocols.XMLRPC.Client("http://www.oreillynet.com/meerkat/xml-rpc/server.php");
   Result: Protocols.XMLRPC.Client("http://www.oreillynet.com/meerkat/xml-rpc/server.php");
   > client["system.listMethods"]();
   Result: ({ /* 1 element */
  		    ({ /* 9 elements */
  			"meerkat.getChannels",
  			"meerkat.getCategories",
  			"meerkat.getCategoriesBySubstring",
  			"meerkat.getChannelsByCategory",
  			"meerkat.getChannelsBySubstring",
  			"meerkat.getItems",
  			"system.listMethods",
  			"system.methodHelp",
  			"system.methodSignature"
