Detailed Description

There are two classes that specifies the protocol between application (job) and tdeioslave.

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.

Definition at line 45 of file slavebase.h.

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 1250 of file slavebase.cpp.

bool SlaveBase::canResume ( TDEIO::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 937 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
infoSee AuthInfo.
Returns
true if cached Authorization is found, false otherwise.

Definition at line 1207 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 TDEIO::ForwardingSlaveBase.

Definition at line 801 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 777 of file slavebase.cpp.

TDEConfigBase * 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 386 of file slavebase.cpp.

void SlaveBase::connected ( )

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

Definition at line 442 of file slavebase.cpp.

void SlaveBase::connectSlave ( const TQString &  path)

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

Definition at line 336 of file slavebase.cpp.

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

Definition at line 1265 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
srcwhere to copy the file from (decoded)
destwhere to copy the file to (decoded)
permissionsmay be -1. In this case no special permission mode is set.
overwriteif true, any existing file will be overwritten

Reimplemented in TDEIO::ForwardingSlaveBase.

Definition at line 795 of file slavebase.cpp.

TQString 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
urlthe url from which the key is supposed to be generated

Definition at line 1166 of file slavebase.cpp.

void SlaveBase::data ( const TQByteArray &  data)

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

in get).

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

Parameters
datathe data read by the slave

Definition at line 409 of file slavebase.cpp.

void SlaveBase::dataReq ( )

Asks for data from the job.

See also
readData

Definition at line 418 of file slavebase.cpp.

DCOPClient * SlaveBase::dcopClient ( )

Return the dcop client used by this slave.

Since
3.1

Definition at line 239 of file slavebase.cpp.

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

Delete a file or directory.

Parameters
urlfile/directory to delete
isfileif true, a file should be deleted. if false, a directory should be deleted.

Reimplemented in TDEIO::ForwardingSlaveBase.

Definition at line 797 of file slavebase.cpp.

void SlaveBase::delCachedAuthentication ( const TQString &  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 718 of file slavebase.cpp.

void SlaveBase::dropNetwork ( const TQString &  host = TQString::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
hostthe host passed to requestNetwork

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

Definition at line 641 of file slavebase.cpp.

void SlaveBase::error ( int  _errid,
const TQString &  _text 
)

Call to signal an error.

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

If the Error code is TDEIO::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
TDEIO::Error
KTextBrowser
Parameters
_erridthe error code from TDEIO::Error
_textthe rich text error message

Definition at line 429 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 554 of file slavebase.cpp.

void SlaveBase::finished ( )

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

Definition at line 449 of file slavebase.cpp.

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

get, aka read.

Parameters
urlthe 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 TDEIO::ForwardingSlaveBase.

Definition at line 787 of file slavebase.cpp.

bool SlaveBase::hasMetaData ( const TQString &  key) const

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

Definition at line 369 of file slavebase.cpp.

bool SlaveBase::hasMetaData ( const TQString &  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 382 of file slavebase.cpp.

void SlaveBase::infoMessage ( const TQString &  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.

Definition at line 620 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 TDEIO::ForwardingSlaveBase.

Definition at line 785 of file slavebase.cpp.

void SlaveBase::listEntries ( const UDSEntryList &  _entry)

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

_entryThe UDSEntry containing all of the object attributes.

Definition at line 697 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
_entryThe UDSEntry containing all of the object attributes.
readyset to true after emitting all items. _entry is not used in this case

void SlaveBase::mimeType ( const TQString &  _type)

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

See mimetype about other ways to implement it.

Definition at line 571 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 TDEIO::ForwardingSlaveBase.

Definition at line 789 of file slavebase.cpp.

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

Create a directory.

Parameters
urlpath to the directory to create
permissionsthe 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 TDEIO::ForwardingSlaveBase.

Definition at line 799 of file slavebase.cpp.

void SlaveBase::multiGet ( const TQByteArray &  data)

Definition at line 752 of file slavebase.h.

void SlaveBase::needSubURLData ( )

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

Definition at line 462 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 775 of file slavebase.cpp.

bool SlaveBase::openPassDlg ( TDEIO::AuthInfo &  info,
const TQString &  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:

TDEIO::AuthInfo authInfo;
if ( openPassDlg( authInfo ) )
{
kdDebug() << TQString::fromLatin1("User: ")
<< authInfo.username << endl;
kdDebug() << TQString::fromLatin1("Password: ")
<< TQString::fromLatin1("Not displayed here!") << endl;
}

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

TDEIO::AuthInfo authInfo;
authInfo.caption= "Acme Password Dialog";
authInfo.username= "Wile E. Coyote";
TQString errorMsg = "You entered an incorrect password.";
if ( openPassDlg( authInfo, errorMsg ) )
{
kdDebug() << TQString::fromLatin1("User: ")
<< authInfo.username << endl;
kdDebug() << TQString::fromLatin1("Password: ")
<< TQString::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
infoSee AuthInfo.
errorMsgError message to show
Returns
true if user clicks on "OK", false otherwsie.

Reimplemented in TDEIO::ForwardingSlaveBase.

Definition at line 791 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 812 of file slavebase.cpp.

bool SlaveBase::requestNetwork ( const TQString &  host = TQString::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
hosttells 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 626 of file slavebase.cpp.

Definition at line 803 of file slavebase.cpp.

void SlaveBase::setTimeoutSpecialCommand ( int  timeout,
const TQByteArray &  data = TQByteArray() 
)

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.

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 540 of file slavebase.cpp.

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

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.

Reimplemented in TDEIO::ForwardingSlaveBase.

Definition at line 779 of file slavebase.cpp.

void SlaveBase::statEntry ( const 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
_entryThe UDSEntry containing all of the object attributes.

void SlaveBase::symlink ( const TQString &  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
targetThe string that will become the "target" of the link (can be relative)
destThe symlink to create.
overwritewhether to automatically overwrite if the dest exists

Reimplemented in TDEIO::ForwardingSlaveBase.

Definition at line 793 of file slavebase.cpp.

void SlaveBase::totalSize ( TDEIO::filesize_t  _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.

Definition at line 482 of file slavebase.cpp.

int SlaveBase::waitForAnswer ( int  expected1,
int  expected2,
TQByteArray &  data,
int *  pCmd = 0 
)

Wait for an answer to our request, until we get expected1 or expected2.

Returns
the result from readData, as well as the cmd in *pCmd if set, and the data in data

void SlaveBase::warning ( const TQString &  msg)

Call to signal a warning, to be displayed in a dialog box.

Definition at line 614 of file slavebase.cpp.

bool SlaveBase::wasKilled ( ) const

If your ioslave was killed by a signal, wasKilled() returns true.

Check it regularly in lengthy functions (e.g. in get();) and return as fast as possible from this function if wasKilled() returns true. This will ensure that your slave destructor will be called correctly.
