SlaveBase Class Reference

from PyKDE4.kio import *

Subclasses: KIO.ForwardingSlaveBase, KIO.TCPSlaveBase
Namespace: KIO

Detailed Description

There are two classes that specifies the protocol between application (job) and kioslave. SlaveInterface is the class to use on the application end, SlaveBase is the one to use on the slave end.

Slave implementations should simply inherit SlaveBase

A call to foo() results in a call to slotFoo() on the other end.

Method Documentation

__init__	(	self,
		QByteArray	protocol,
		QByteArray	pool_socket,
		QByteArray	app_socket
	)

__init__	(	self,
		KIO.SlaveBase	other
	)

KIO.MetaData allMetaData ( self )

Internal:: for ForwardingSlaveBase Contains all metadata (but no config) sent by the application to the slave.

bool cacheAuthentication	(	self,
		KIO.AuthInfo	info
	)

Explicitly store authentication information. openPasswordDialog already stores password information automatically, you only need to call this function if you want to store authentication information that is different from the information returned by openPasswordDialog.

bool canResume	(	self,
		long	offset
	)

Call this at the beginning of get(), if the "resume" metadata was set and resuming is implemented by this protocol.

canResume ( self )

Call this at the beginning of get(), if the "resume" metadata was set and resuming is implemented by this protocol.

bool checkCachedAuthentication	(	self,
		KIO.AuthInfo	info
	)

Checks for cached authentication based on parameters given by info.

Use this function to check if any cached password exists for the URL given by info. If AuthInfo.realmValue and/or AuthInfo.verifyPath flag is specified, then they will also be factored in determining the presence of a cached password. Note that Auth.url is a required parameter when attempting to check for cached authorization info. Here is a simple example:

 AuthInfo info;
 info.url = KUrl("http://www.foobar.org/foo/bar");
 info.username = "somename";
 info.verifyPath = true;
 if ( !checkCachedAuthentication( info ) )
 {
    if ( !openPasswordDialog(info) )
     ....
 }

Parameters:

info See AuthInfo.

Returns:: true if cached Authorization is found, false otherwise.

chmod	(	self,
		KUrl	url,
		int	permissions
	)

Change permissions on url The slave emits ERR_DOES_NOT_EXIST or ERR_CANNOT_CHMOD

chown	(	self,
		KUrl	url,
		QString	owner,
		QString	group
	)

Change ownership of url The slave emits ERR_DOES_NOT_EXIST or ERR_CANNOT_CHOWN

close ( self )

closeConnection ( self )

Closes the connection (forced) Called when the application disconnects the slave to close any open network connections.

When the slave was operating in connection-oriented mode, it should reset itself to connectionless (default) mode.

KConfigGroup config ( self )

Returns a configuration object to query config/meta-data information from.

The application provides the slave with all configuration information relevant for the current protocol and host.

connectSlave	(	self,
		QString	path
	)

internal function to connect a slave to/ disconnect from either the slave pool or the application

int connectTimeout ( self )

Returns:: timeout value for connecting to remote host.

connected ( self )

Call in openConnection, if you reimplement it, when you're done.

copy	(	self,
		KUrl	src,
		KUrl	dest,
		int	permissions,
		KIO.JobFlags	flags
	)

Copy src into dest.

By default, copy() is only called when copying a file from yourproto://host/path to yourproto://host/otherpath.

If you set copyFromFile=true then copy() will also be called when moving a file from file:path to yourproto://host/otherpath. Otherwise such a copy would have to be done the slow way (get+put). See also KProtocolManager.canCopyFromFile().

If you set copyToFile=true then copy() will also be called when moving a file from yourproto: to file:. See also KProtocolManager.canCopyToFile().

If the slave returns an error ERR_UNSUPPORTED_ACTION, the job will ask for get + put instead.

Parameters:

	src	where to copy the file from (decoded)
	dest	where to copy the file to (decoded)
	permissions	may be -1. In this case no special permission mode is set.
	flags:	We support Overwrite here

Don't forget to set the modification time of dest to be the modification time of src.

data	(	self,
		QByteArray	data
	)

Sends data in the slave to the job (i.e. in get).

To signal end of data, simply send an empty QByteArray().

Parameters:

data

the data read by the slave

dataReq ( self )

Asks for data from the job.

See also:: readData

del_	(	self,
		KUrl	url,
		bool	isfile
	)

Delete a file or directory.

Parameters:

	url	file/directory to delete
	isfile	if true, a file should be deleted. if false, a directory should be deleted.

By default, del() on a directory should FAIL if the directory is not empty. However, if metadata("recurse") == "true", then the slave can do a recursive deletion. This behavior is only invoked if the slave specifies deleteRecursive=true in its protocol file.

disconnectSlave ( self )

dispatch	(	self,
		int	command,
		QByteArray	data
	)

Internal:

dispatchLoop ( self )

Internal:

dispatchOpenCommand	(	self,
		int	command,
		QByteArray	data
	)

Internal:

dropNetwork	(	self,
		QString	host=QString()
	)

Used by the slave to withdraw a connection requested by requestNetwork. This function cancels the last call to requestNetwork. If a client uses more than one internet connection, it must use dropNetwork(host) to stop each request.

If KNetMgr is not running, then this is a no-op.

Parameters:

host

the host passed to requestNetwork

A slave should call this function every time it disconnect from a host.

error	(	self,
		int	_errid,
		QString	_text
	)

Call to signal an error. This also finishes the job, so you must not call finished() after calling this.

If the error code is KIO.ERR_SLAVE_DEFINED then the _text should contain the complete translated text of of the error message.

For all other error codes, _text should match the corresponding error code. Usually,, _text is a file or host name, or the error which was passed from the server.
For example, for KIO.ERR_DOES_NOT_EXIST, _text may only be the file or folder which does not exist, nothing else. Otherwise, this would break error strings generated by KIO.buildErrorString().
If you have to add more details than what the standard error codes provide, you'll need to use KIO.ERR_SLAVE_DEFINED. For a complete list of what _text should contain for each error code, look at the source of KIO.buildErrorString().

You can add rich text markup to the message, the places where the error message will be displayed are rich text aware.

See also:: KIO.Error

See also:: KIO.buildErrorString

Parameters:

	_errid	the error code from KIO.Error
	_text	the rich text error message

errorPage ( self )

Tell that we will only get an error page here. This means: the data you'll get isn't the data you requested, but an error page (usually HTML) that describes an error.

exit ( self )

Internal:: Terminate the slave by calling the destructor and then .exit()

finished ( self )

Call to signal successful completion of any command besides openConnection and closeConnection. Do not call this after calling error().

get	(	self,
		KUrl	url
	)

get, aka read.

Parameters:

url

the full url for this request. Host, port and user of the URL can be assumed to be the same as in the last setHost() call.

The slave should first "emit" the mimetype by calling mimeType(), and then "emit" the data using the data() method.

The reason why we need get() to emit the mimetype is: when pasting a URL in krunner, or konqueror's location bar, we have to find out what is the mimetype of that URL. Rather than doing it with a call to mimetype(), then the app or part would have to do a second request to the same server, this is done like this: get() is called, and when it emits the mimetype, the job is put on hold and the right app or part is launched. When that app or part calls get(), the slave is magically reused, and the download can now happen. All with a single call to get() in the slave. This mechanism is also described in KIO.get().

bool hasMetaData	(	self,
		QString	key
	)

Queries for the existence of a certain config/meta-data entry send by the application to the slave.

infoMessage	(	self,
		QString	msg
	)

Call to signal a message, to be displayed if the application wants to, for instance in a status bar. Usual examples are "connecting to host xyz", etc.

listDir	(	self,
		KUrl	url
	)

Lists the contents of url. The slave should emit ERR_CANNOT_ENTER_DIRECTORY if it doesn't exist, if we don't have enough permissions, or if it is a file It should also emit totalFiles as soon as it knows how many files it will list.

listEntries	(	self,
		[KIO.UDSEntry]	_entry
	)

Call this in listDir, each time you have a bunch of entries to report.

Parameters:

_entry

The UDSEntry containing all of the object attributes.

listEntry	(	self,
		KIO.UDSEntry	_entry,
		bool	ready
	)

internal function to be called by the slave. It collects entries and emits them via listEntries when enough of them are there or a certain time frame exceeded (to make sure the app gets some items in time but not too many items one by one as this will cause a drastic performance penalty)

Parameters:

	_entry	The UDSEntry containing all of the object attributes.
	ready	set to true after emitting all items. _entry is not used in this case

lookupHost	(	self,
		QString	host
	)

Internally used

Internal:

int messageBox	(	self,
		KIO.SlaveBase.MessageBoxType	type,
		QString	text,
		QString	caption=QString(),
		QString	buttonYes=i18n("&Yes"),
		QString	buttonNo=i18n("&No")
	)

Call this to show a message box from the slave

Parameters:

	text	Message string. May contain newlines.
	type	type of message box: QuestionYesNo, WarningYesNo, WarningContinueCancel...
	caption	Message box title.
	buttonYes	The text for the first button. The default is i18n("&Yes").
	buttonNo	The text for the second button. The default is i18n("&No"). Note: for ContinueCancel, buttonYes is the continue button and buttonNo is unused. and for Information, none is used.
	dontAskAgain	A checkbox is added with which further confirmation can be turned off. If the checkbox was ticked @p*dontAskAgain will be set to true, otherwise false.

Returns:: a button code, as defined in KMessageBox, or 0 on communication error.

int messageBox	(	self,
		QString	text,
		KIO.SlaveBase.MessageBoxType	type,
		QString	caption=QString(),
		QString	buttonYes=i18n("&Yes"),
		QString	buttonNo=i18n("&No"),
		QString	dontAskAgainName=QString()
	)

Call this to show a message box from the slave

Parameters:

	text	Message string. May contain newlines.
	type	type of message box: QuestionYesNo, WarningYesNo, WarningContinueCancel...
	caption	Message box title.
	buttonYes	The text for the first button. The default is i18n("&Yes").
	buttonNo	The text for the second button. The default is i18n("&No"). Note: for ContinueCancel, buttonYes is the continue button and buttonNo is unused. and for Information, none is used.
	dontAskAgain	A checkbox is added with which further confirmation can be turned off. If the checkbox was ticked @p*dontAskAgain will be set to true, otherwise false.

Returns:: a button code, as defined in KMessageBox, or 0 on communication error.

QString metaData	(	self,
		QString	key
	)

Queries for config/meta-data send by the application to the slave.

mimeType	(	self,
		QString	_type
	)

Call this in mimetype() and in get(), when you know the mimetype. See mimetype about other ways to implement it.

mimetype	(	self,
		KUrl	url
	)

Finds mimetype for one file or directory.

This method should either emit 'mimeType' or it should send a block of data big enough to be able to determine the mimetype.

If the slave doesn't reimplement it, a get will be issued, i.e. the whole file will be downloaded before determining the mimetype on it - this is obviously not a good thing in most cases.

mkdir	(	self,
		KUrl	url,
		int	permissions
	)

Create a directory

Parameters:

	url	path to the directory to create
	permissions	the permissions to set after creating the directory (-1 if no permissions to be set) The slave emits ERR_COULD_NOT_MKDIR if failure.

multiGet	(	self,
		QByteArray	data
	)

Used for multiple get. Currently only used foir HTTP pielining support.

Parameters:

data

packed data; Contains number of URLs to fetch, and for each URL the URL itself and its associated MetaData.

needSubUrlData ( self )

Call to signal that data from the sub-URL is needed

open	(	self,
		KUrl	url,
		QIODevice.OpenMode	mode
	)

open.

Parameters:

	url	the full url for this request. Host, port and user of the URL can be assumed to be the same as in the last setHost() call.
	mode	see QIODevice.OpenMode

openConnection ( self )

Opens the connection (forced) When this function gets called the slave is operating in connection-oriented mode. When a connection gets lost while the slave operates in connection oriented mode, the slave should report ERR_CONNECTION_BROKEN instead of reconnecting. The user is expected to disconnect the slave in the error handler.

bool openPasswordDialog	(	self,
		KIO.AuthInfo	info,
		QString	errorMsg=QString()
	)

Prompt the user for Authorization info (login & password).

Use this function to request authorization information from the end user. You can also pass an error message which explains why a previous authorization attempt failed. Here is a very simple example:

 KIO.AuthInfo authInfo;
 if ( openPasswordDialog( authInfo ) )
 {
    kDebug() << QLatin1String("User: ")
              << authInfo.username << endl;
    kDebug() << QLatin1String("Password: ")
              << QLatin1String("Not displayed here!") << endl;
 }

You can also preset some values like the username, caption or comment as follows:

 KIO.AuthInfo authInfo;
 authInfo.caption= "Acme Password Dialog";
 authInfo.username= "Wile E. Coyote";
 QString errorMsg = "You entered an incorrect password.";
 if ( openPasswordDialog( authInfo, errorMsg ) )
 {
    kDebug() << QLatin1String("User: ")
              << authInfo.username << endl;
    kDebug() << QLatin1String("Password: ")
              << QLatin1String("Not displayed here!") << endl;
 }

Note:: You should consider using checkCachedAuthentication() to see if the password is available in kpasswdserver before calling this function.

Note:: A call to this function can fail and return false, if the UIServer could not be started for whatever reason.

See also:: checkCachedAuthentication

Parameters:

	info	See AuthInfo.
	errorMsg	Error message to show

Returns:: true if user clicks on "OK", false otherwsie.

opened ( self )

open succedes

See also:: open

position	(	self,
		long	_pos
	)

processedPercent	(	self,
		float	percent
	)

Only use this if you can't know in advance the size of the copied data. For example, if you're doing variable bitrate compression of the source.

STUB ! Currently unimplemented. Here now for binary compatibility.

Call this during get and copy, once in a while, to give some info about the current state. Don't emit it in listDir, listEntries speaks for itself.

processedSize	(	self,
		long	_bytes
	)

Call this during get and copy, once in a while, to give some info about the current state. Don't emit it in listDir, listEntries speaks for itself.

int proxyConnectTimeout ( self )

Returns:: timeout value for connecting to proxy in secs.

put	(	self,
		KUrl	url,
		int	permissions,
		KIO.JobFlags	flags
	)

put, i.e. write data into a file.

Parameters:

	url	where to write the file
	permissions	may be -1. In this case no special permission mode is set.
	flags:	We support Overwrite here. Hopefully, we're going to support Resume in the future, too. If the file indeed already exists, the slave should NOT apply the permissions change to it. The support for resuming using .part files is done by calling canResume().

IMPORTANT: Use the "modified" metadata in order to set the modification time of the file.

See also:: canResume()

read	(	self,
		long	size
	)

int readData	(	self,
		QByteArray	buffer
	)

Read data sent by the job, after a dataReq

Parameters:

buffer

buffer where data is stored

Returns:: 0 on end of data, > 0 bytes read < 0 error

int readTimeout ( self )

Returns:: timeout value for read from subsequent data from remote host in secs.

redirection	(	self,
		KUrl	_url
	)

Call this to signal a redirection The job will take care of going to that url.

KRemoteEncoding remoteEncoding ( self )

Returns an object that can translate remote filenames into proper Unicode forms. This encoding can be set by the user.

rename	(	self,
		KUrl	src,
		KUrl	dest,
		KIO.JobFlags	flags
	)

Rename oldname into newname. If the slave returns an error ERR_UNSUPPORTED_ACTION, the job will ask for copy + del instead.

Important: the slave must implement the logic "if the destination already exists, error ERR_DIR_ALREADY_EXIST or ERR_FILE_ALREADY_EXIST". For performance reasons no stat is done in the destination before hand, the slave must do it.

By default, rename() is only called when renaming (moving) from yourproto://host/path to yourproto://host/otherpath.

If you set renameFromFile=true then rename() will also be called when moving a file from file:path to yourproto://host/otherpath. Otherwise such a move would have to be done the slow way (copy+delete). See KProtocolManager.canRenameFromFile() for more details.

If you set renameToFile=true then rename() will also be called when moving a file from yourproto: to file:. See KProtocolManager.canRenameToFile() for more details.

Parameters:

	src	where to move the file from
	dest	where to move the file to
	flags:	We support Overwrite here

reparseConfiguration ( self )

Called by the scheduler to tell the slave that the configuration changed (i.e. proxy settings) .

bool requestNetwork	(	self,
		QString	host=QString()
	)

Used by the slave to check if it can connect to a given host. This should be called where the slave is ready to do a .connect() on a socket. For each call to requestNetwork must exist a matching call to dropNetwork, or the system will stay online until KNetMgr gets closed (or the SlaveBase gets destructed)!

If KNetMgr is not running, then this is a no-op and returns true

Parameters:

host

tells the netmgr the host the slave wants to connect to. As this could also be a proxy, we can't just take the host currenctly connected to (but that's the default value)

Returns:: true in theorie, the host is reachable false the system is offline and the host is in a remote network.

int responseTimeout ( self )

Returns:: timeout value for read from first data from remote host in seconds.

seek	(	self,
		long	offset
	)

sendAndKeepMetaData ( self )

Internal function to transmit meta data to the application. Like sendMetaData() but m_outgoingMetaData will not be cleared. This method is mainly useful in code that runs before the slave is connected to its final job.

sendMetaData ( self )

Internal function to transmit meta data to the application. m_outgoingMetaData will be cleared; this means that if the slave is for example put on hold and picked up by a different KIO.Job later the new job will not see the metadata sent before. See kio/DESIGN.krun for an overview of the state progression of a job/slave.

Warning:: calling this method may seriously interfere with the operation of KIO which relies on the presence of some metadata at some points in time. You should not use it if you are not familiar with KIO and not before the slave is connected to the last job before returning to idle state.

setHost	(	self,
		QString	host,
		int	port,
		QString	user,
		QString	pass
	)

Set the host

Parameters:

	host
	port
	user
	pass	Called directly by createSlave, this is why there is no equivalent in SlaveInterface, unlike the other methods.

This method is called whenever a change in host, port or user occurs.

setKillFlag ( self )

Internally used.

Internal:

setLinkDest	(	self,
		KUrl	url,
		QString	target
	)

Change the destination of a symlink

Parameters:

	url	the url of the symlink to modify
	target	the new destination (target) of the symlink

setMetaData	(	self,
		QString	key,
		QString	value
	)

Sets meta-data to be send to the application before the first data() or finished() signal.

setModificationTime	(	self,
		KUrl	url,
		QDateTime	mtime
	)

Sets the modification time for url For instance this is what CopyJob uses to set mtime on dirs at the end of a copy. It could also be used to set the mtime on any file, in theory. The usual implementation on unix is to call utime(path, &myutimbuf). The slave emits ERR_DOES_NOT_EXIST or ERR_CANNOT_SETTIME

setSubUrl	(	self,
		KUrl	url
	)

Prepare slave for streaming operation

setTimeoutSpecialCommand	(	self,
		int	timeout,
		QByteArray	data=QByteArray()
	)

This function sets a timeout of timeout seconds and calls special(data) when the timeout occurs as if it was called by the application.

A timeout can only occur when the slave is waiting for a command from the application.

Specifying a negative timeout cancels a pending timeout.

Only one timeout at a time is supported, setting a timeout cancels any pending timeout.

slaveStatus	(	self,
		QString	host,
		bool	connected
	)

Used to report the status of the slave.

Parameters:

	host	the slave is currently connected to. (Should be empty if not connected)
	connected	Whether an actual network connection exists.

slave_status ( self )

Called to get the status of the slave. Slave should respond by calling slaveStatus(...)

special	(	self,
		QByteArray	data
	)

Used for any command that is specific to this slave (protocol) Examples are : HTTP POST, mount and unmount (kio_file)

Parameters:

data

packed data; the meaning is completely dependent on the slave, but usually starts with an int for the command number. Document your slave's commands, at least in its header file.

speed	(	self,
		long	_bytes_per_second
	)

Call this in get and copy, to give the current transfer speed, but only if it can't be calculated out of the size you passed to processedSize (in most cases you don't want to call it)

stat	(	self,
		KUrl	url
	)

Finds all details for one file or directory. The information returned is the same as what listDir returns, but only for one file or directory. Call statEntry() after creating the appropriate UDSEntry for this url.

You can use the "details" metadata to optimize this method to only do as much work as needed by the application. By default details is 2 (all details wanted, including modification time, size, etc.), details==1 is used when deleting: we don't need all the information if it takes too much time, no need to follow symlinks etc. details==0 is used for very simple probing: we'll only get the answer "it's a file or a directory (or a symlink), or it doesn't exist".

statEntry	(	self,
		KIO.UDSEntry	_entry
	)

Call this from stat() to express details about an object, the UDSEntry customarily contains the atoms describing file name, size, mimetype, etc.

Parameters:

_entry

The UDSEntry containing all of the object attributes.

symlink	(	self,
		QString	target,
		KUrl	dest,
		KIO.JobFlags	flags
	)

Creates a symbolic link named dest, pointing to target, which may be a relative or an absolute path.

Parameters:

	target	The string that will become the "target" of the link (can be relative)
	dest	The symlink to create.
	flags:	We support Overwrite here

totalSize	(	self,
		long	_bytes
	)

Call this in get and copy, to give the total size of the file Call in listDir too, when you know the total number of items.

int, int pCmd waitForAnswer	(	self,
		int	expected1,
		int	expected2,
		QByteArray	data
