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.

Member Function Documentation

bool SlaveBase::cacheAuthentication ( const AuthInfo info  ) 

Explicitly store authentication information.

openPassDlg 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 openPassDlg.

Definition at line 1222 of file slavebase.cpp.

bool SlaveBase::canResume ( KIO::filesize_t  offset  ) 

Call this at the beginning of put(), to give the size of the existing partial file, if there is one.

The offset argument notifies the other job (the one that gets the data) about the offset to use. In this case, the boolean returns whether we can indeed resume or not (we can't if the protocol doing the get() doesn't support setting an offset)

Definition at line 914 of file slavebase.cpp.

bool SlaveBase::checkCachedAuthentication ( 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 ( !openPassDlg(info) )
     ....
 }
Parameters:
info See AuthInfo.
Returns:
true if cached Authorization is found, false otherwise.

Definition at line 1179 of file slavebase.cpp.

void SlaveBase::chmod ( const KURL &  url,
int  permissions 
) [virtual]

Change permissions on path The slave emits ERR_DOES_NOT_EXIST or ERR_CANNOT_CHMOD.

Reimplemented in KIO::ForwardingSlaveBase.

Definition at line 795 of file slavebase.cpp.

void SlaveBase::closeConnection ( void   )  [virtual]

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.

Definition at line 771 of file slavebase.cpp.

KConfigBase * SlaveBase::config (  ) 

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.

Definition at line 390 of file slavebase.cpp.

void SlaveBase::connected (  ) 

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

Definition at line 446 of file slavebase.cpp.

void SlaveBase::connectSlave ( const QString path  ) 

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

Definition at line 340 of file slavebase.cpp.

int SlaveBase::connectTimeout (  ) 
Returns:
timeout value for connecting to remote host.

Definition at line 1237 of file slavebase.cpp.

void SlaveBase::copy ( const KURL &  src,
const KURL &  dest,
int  permissions,
bool  overwrite 
) [virtual]

Copy src into dest.

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.
overwrite if true, any existing file will be overwritten

Reimplemented in KIO::ForwardingSlaveBase.

Definition at line 789 of file slavebase.cpp.

QString SlaveBase::createAuthCacheKey ( const KURL &  url  ) 
Deprecated:
as of 3.1. Use openPassDlg instead. TODO: Remove before KDE 4.0 Creates a basic key to be used to cache the password.
Parameters:
url the url from which the key is supposed to be generated

Definition at line 1138 of file slavebase.cpp.

void SlaveBase::data ( const 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

Definition at line 413 of file slavebase.cpp.

void SlaveBase::dataReq (  ) 

Asks for data from the job.

See also:
readData

Definition at line 422 of file slavebase.cpp.

DCOPClient * SlaveBase::dcopClient (  ) 

Return the dcop client used by this slave.

Since:
3.1

Definition at line 245 of file slavebase.cpp.

void SlaveBase::del ( const KURL &  url,
bool  isfile 
) [virtual]

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.

Reimplemented in KIO::ForwardingSlaveBase.

Definition at line 791 of file slavebase.cpp.

void SlaveBase::delCachedAuthentication ( const QString key  ) 
Deprecated:
as of 3.1. Use openPassDlg instead. TODO: Remove before KDE 4.0

Cached authentication information is now session based and removed automatically when a given session ends, i.e. the application is closed.

Definition at line 722 of file slavebase.cpp.

void SlaveBase::dropNetwork ( const QString host = QString::null  ) 

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.

Definition at line 645 of file slavebase.cpp.

void SlaveBase::error ( int  _errid,
const QString _text 
)

Call to signal an error.

This also finishes the job, no need to call finished.

If the Error code is KIO::ERR_SLAVE_DEFINED then the _text should contain the complete translated text of of the error message. This message will be displayed in an KTextBrowser which allows rich text complete with hyper links. Email links will call the default mailer, "exec:/command arg1 arg2" will be forked and all other links will call the default browser.

See also:
KIO::Error
KTextBrowser
Parameters:
_errid the error code from KIO::Error
_text the rich text error message

Definition at line 433 of file slavebase.cpp.

void SlaveBase::errorPage (  ) 

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.

Definition at line 558 of file slavebase.cpp.

void SlaveBase::finished (  ) 

Call to signal successful completion of any command (besides openConnection and closeConnection).

Definition at line 453 of file slavebase.cpp.

void SlaveBase::get ( const KURL &  url  )  [virtual]

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 emits the data through data

Reimplemented in KIO::ForwardingSlaveBase.

Definition at line 781 of file slavebase.cpp.

bool SlaveBase::hasMetaData ( const QString key  ) 
Deprecated:
kept for binary compatibility Queries for the existence of a certain config/meta-data entry send by the application to the slave.

Definition at line 386 of file slavebase.cpp.

bool SlaveBase::hasMetaData ( const QString key  )  const

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

Since:
3.2

Definition at line 373 of file slavebase.cpp.

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.

Definition at line 624 of file slavebase.cpp.

void SlaveBase::listDir ( const KURL &  url  )  [virtual]

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.

Reimplemented in KIO::ForwardingSlaveBase.

Definition at line 779 of file slavebase.cpp.

void SlaveBase::listEntries ( const UDSEntryList _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.

Definition at line 701 of file slavebase.cpp.

void SlaveBase::listEntry ( const 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

Definition at line 659 of file slavebase.cpp.

int SlaveBase::messageBox ( const QString text,
MessageBoxType  type,
const QString caption = QString::null,

dontAskAgainName A checkbox is added with which further confirmation can be turned off. The string is used to lookup and store the setting in kioslaverc.
Returns:
a button code, as defined in KMessageBox, or 0 on communication error.
Since:

text Message string. May contain newlines.
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.
Returns:
a button code, as defined in KMessageBox, or 0 on communication error.

Definition at line 891 of file slavebase.cpp.

QString SlaveBase::metaData ( const QString key  ) 
Deprecated:
kept for binary compatibility Queries for config/meta-data sent by the application to the slave.

Definition at line 383 of file slavebase.cpp.

QString SlaveBase::metaData ( const QString key  )  const

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

Since:
3.2

Definition at line 364 of file slavebase.cpp.

void SlaveBase::mimetype ( const KURL &  url  )  [virtual]

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.

Reimplemented in KIO::ForwardingSlaveBase.

Definition at line 783 of file slavebase.cpp.

void SlaveBase::mimeType ( const QString _type  ) 

Call this in mimetype() and in get(), when you know the mimetype.

See mimetype about other ways to implement it.

Definition at line 575 of file slavebase.cpp.

void SlaveBase::mkdir ( const KURL &  url,
int  permissions 
) [virtual]

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.

Reimplemented in KIO::ForwardingSlaveBase.

Definition at line 793 of file slavebase.cpp.

void SlaveBase::multiGet ( const QByteArray data  )  [virtual]

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.

Definition at line 799 of file slavebase.cpp.

bool KIO::SlaveBase::multipleAuthCaching (  )  const [inline]
Deprecated:
as of 3.1. Use openPassDlg instead. TODO: Remove before KDE 4.0

Definition at line 746 of file slavebase.h.

void SlaveBase::needSubURLData (  ) 

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

Definition at line 466 of file slavebase.cpp.

void SlaveBase::openConnection ( void   )  [virtual]

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.

Definition at line 769 of file slavebase.cpp.

bool SlaveBase::openPassDlg ( KIO::AuthInfo info  ) 

Same as above function except it does not need error message.

BIC: Combine this function with the above for KDE4.

Definition at line 826 of file slavebase.cpp.

bool SlaveBase::openPassDlg ( KIO::AuthInfo info,
const QString errorMsg 
)

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 ( openPassDlg( authInfo ) )
 {
    kdDebug() << QString::fromLatin1("User: ")
              << authInfo.username << endl;
    kdDebug() << QString::fromLatin1("Password: ")
              << QString::fromLatin1("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 ( openPassDlg( authInfo, errorMsg ) )
 {
    kdDebug() << QString::fromLatin1("User: ")
              << authInfo.username << endl;
    kdDebug() << QString::fromLatin1("Password: ")
              << QString::fromLatin1("Not displayed here!") << endl;
 }
Note:
You should consider using checkCachedAuthentication() to see if the password is available in kpasswdserver before calling this function.
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.

Deprecated:
as of 3.1. TODO: Remove before KDE 4.0

Definition at line 1157 of file slavebase.cpp.

void SlaveBase::processedPercent ( 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.

Definition at line 538 of file slavebase.cpp.

void SlaveBase::processedSize ( KIO::filesize_t  _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.

Definition at line 502 of file slavebase.cpp.

int SlaveBase::proxyConnectTimeout (  ) 
Returns:
timeout value for connecting to proxy in secs.

Definition at line 1247 of file slavebase.cpp.

void SlaveBase::put ( const KURL &  url,
int  permissions,
bool  overwrite,
bool  resume 
) [virtual]

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.
overwrite if true, any existing file will be overwritten. If the file indeed already exists, the slave should NOT apply the permissions change to it.
resume currently unused, please ignore. 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()

Reimplemented in KIO::ForwardingSlaveBase.

Definition at line 775 of file slavebase.cpp.

int SlaveBase::readData ( QByteArray buffer  ) 

Read data send by the job, after a dataReq.

Parameters:
buffer buffer where data is stored
Returns:
0 on end of data, > 0 bytes read < 0 error

void SlaveBase::redirection ( const KURL &  _url  ) 

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

Definition at line 552 of file slavebase.cpp.

KRemoteEncoding * SlaveBase::remoteEncoding (  ) 

Returns an object that can translate remote filenames into proper Unicode forms.

This encoding can be set by the user.

Since:
3.3

Definition at line 405 of file slavebase.cpp.

void SlaveBase::rename ( const KURL &  src,
const KURL &  dest,
bool  overwrite 
) [virtual]

Rename oldname into newname.

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

Parameters:
src where to move the file from
dest where to move the file to
overwrite if true, any existing file will be overwritten

Reimplemented in KIO::ForwardingSlaveBase.

Definition at line 785 of file slavebase.cpp.

void SlaveBase::reparseConfiguration (  )  [virtual]

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

proxy settings) .

Definition at line 806 of file slavebase.cpp.

bool SlaveBase::requestNetwork ( const QString host = QString::null  ) 

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.

Definition at line 630 of file slavebase.cpp.

int SlaveBase::responseTimeout (  ) 
Returns:
timeout value for read from first data from remote host in seconds.

Definition at line 1258 of file slavebase.cpp.

void SlaveBase::sendAuthenticationKey ( const QCString gKey,
const QCString key,
bool  keep 
)
Deprecated:
as of 3.1. Use openPassDlg instead. TODO: Remove before KDE 4.0

Cache authentication information is now stored automatically by openPassDlg.

Definition at line 714 of file slavebase.cpp.

void SlaveBase::sendMetaData (  ) 

Internal function to transmit meta data to the application.

Definition at line 395 of file slavebase.cpp.

void SlaveBase::setHost ( const QString host,
int  port,
const QString user,
const QString pass 
) [virtual]

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.

Definition at line 765 of file slavebase.cpp.

void SlaveBase::setKillFlag (  ) 

Internally used.

Definition at line 1284 of file slavebase.cpp.

void SlaveBase::setMetaData ( const QString key,
const QString value 
)

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

Definition at line 359 of file slavebase.cpp.

void KIO::SlaveBase::setMultipleAuthCaching ( bool   )  [inline]
Deprecated:
as of 3.1. Use openPassDlg instead. TODO: Remove before KDE 4.0

Definition at line 740 of file slavebase.h.

void SlaveBase::setSubURL ( const KURL &  url  )  [virtual]

Prepare slave for streaming operation.

Definition at line 797 of file slavebase.cpp.

void SlaveBase::setTimeoutSpecialCommand ( int  timeout,
const 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.

Since:
3.1

Definition at line 971 of file slavebase.cpp.

void SlaveBase::slave_status (  )  [virtual]

Called to get the status of the slave.

Slave should respond by calling slaveStatus(...)

void SlaveBase::slaveStatus ( const 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.

Definition at line 471 of file slavebase.cpp.

void SlaveBase::special ( const QByteArray data  )  [virtual]

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.

Definition at line 777 of file slavebase.cpp.

void SlaveBase::speed ( unsigned 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).

Definition at line 544 of file slavebase.cpp.

void SlaveBase::stat ( const KURL &  url  )  [virtual]

void SlaveBase::symlink ( const QString target,
const KURL &  dest,
bool  overwrite 
) [virtual]

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

Parameters:
