GI.Gio.Objects.TlsInteraction

TlsInteraction provides a mechanism for the TLS connection and database code to interact with the user. It can be used to ask the user for passwords.

To use a TlsInteraction with a TLS connection use tlsConnectionSetInteraction.

Callers should instantiate a derived class that implements the various interaction methods to show the required dialogs.

Callers should use the 'invoke' functions like tlsInteractionInvokeAskPassword to run interaction methods. These functions make sure that the interaction is invoked in the main loop and not in the current thread, if the current thread is not running the main loop.

Derived classes can choose to implement whichever interactions methods they'd like to support by overriding those virtual methods in their class initialization function. Any interactions not implemented will return TlsInteractionResultUnhandled. If a derived class implements an async method, it must also implement the corresponding finish method.

Methods

askPassword

tlsInteractionAskPassword

Arguments

:: (HasCallStack, MonadIO m, IsTlsInteraction a, IsTlsPassword b, IsCancellable c)

=> a

interaction: a TlsInteraction object

-> b

password: a TlsPassword object

-> Maybe c

cancellable: an optional Cancellable cancellation object

-> m TlsInteractionResult

Returns: The status of the ask password interaction. (Can throw GError)

Run synchronous interaction to ask the user for a password. In general, tlsInteractionInvokeAskPassword should be used instead of this function.

Derived subclasses usually implement a password prompt, although they may also choose to provide a password from elsewhere. The password value will be filled in and then callback will be called. Alternatively the user may abort this password request, which will usually abort the TLS connection.

If the interaction is cancelled by the cancellation object, or by the user then TlsInteractionResultFailed will be returned with an error that contains a IOErrorEnumCancelled error code. Certain implementations may not support immediate cancellation.

askPasswordAsync

tlsInteractionAskPasswordAsync

Arguments

:: (HasCallStack, MonadIO m, IsTlsInteraction a, IsTlsPassword b, IsCancellable c)

=> a

interaction: a TlsInteraction object

-> b

password: a TlsPassword object

-> Maybe c

cancellable: an optional Cancellable cancellation object

-> Maybe AsyncReadyCallback

callback: will be called when the interaction completes

-> m ()

Run asynchronous interaction to ask the user for a password. In general, tlsInteractionInvokeAskPassword should be used instead of this function.

Derived subclasses usually implement a password prompt, although they may also choose to provide a password from elsewhere. The password value will be filled in and then callback will be called. Alternatively the user may abort this password request, which will usually abort the TLS connection.

If the interaction is cancelled by the cancellation object, or by the user then TlsInteractionResultFailed will be returned with an error that contains a IOErrorEnumCancelled error code. Certain implementations may not support immediate cancellation.

askPasswordFinish

tlsInteractionAskPasswordFinish

Arguments

:: (HasCallStack, MonadIO m, IsTlsInteraction a, IsAsyncResult b)

=> a

interaction: a TlsInteraction object

-> b

result: the result passed to the callback

-> m TlsInteractionResult

Returns: The status of the ask password interaction. (Can throw GError)

Complete an ask password user interaction request. This should be once the tlsInteractionAskPasswordAsync completion callback is called.

If TlsInteractionResultHandled is returned, then the TlsPassword passed to tlsInteractionAskPassword will have its password filled in.

If the interaction is cancelled by the cancellation object, or by the user then TlsInteractionResultFailed will be returned with an error that contains a IOErrorEnumCancelled error code.

invokeAskPassword

tlsInteractionInvokeAskPassword

Arguments

:: (HasCallStack, MonadIO m, IsTlsInteraction a, IsTlsPassword b, IsCancellable c)

=> a

interaction: a TlsInteraction object

-> b

password: a TlsPassword object

-> Maybe c

cancellable: an optional Cancellable cancellation object

-> m TlsInteractionResult

Returns: The status of the ask password interaction. (Can throw GError)

Invoke the interaction to ask the user for a password. It invokes this interaction in the main loop, specifically the MainContext returned by mainContextGetThreadDefault when the interaction is created. This is called by called by TlsConnection or TlsDatabase to ask the user for a password.

Derived subclasses usually implement a password prompt, although they may also choose to provide a password from elsewhere. The password value will be filled in and then callback will be called. Alternatively the user may abort this password request, which will usually abort the TLS connection.

The implementation can either be a synchronous (eg: modal dialog) or an asynchronous one (eg: modeless dialog). This function will take care of calling which ever one correctly.

If the interaction is cancelled by the cancellation object, or by the user then TlsInteractionResultFailed will be returned with an error that contains a IOErrorEnumCancelled error code. Certain implementations may not support immediate cancellation.

invokeRequestCertificate

tlsInteractionInvokeRequestCertificate

Arguments

:: (HasCallStack, MonadIO m, IsTlsInteraction a, IsTlsConnection b, IsCancellable c)

=> a

interaction: a TlsInteraction object

-> b

connection: a TlsConnection object

-> TlsCertificateRequestFlags

flags: flags providing more information about the request

-> Maybe c

cancellable: an optional Cancellable cancellation object

-> m TlsInteractionResult

Returns: The status of the certificate request interaction. (Can throw GError)

Invoke the interaction to ask the user to choose a certificate to use with the connection. It invokes this interaction in the main loop, specifically the MainContext returned by mainContextGetThreadDefault when the interaction is created. This is called by called by TlsConnection when the peer requests a certificate during the handshake.

Derived subclasses usually implement a certificate selector, although they may also choose to provide a certificate from elsewhere. Alternatively the user may abort this certificate request, which may or may not abort the TLS connection.

The implementation can either be a synchronous (eg: modal dialog) or an asynchronous one (eg: modeless dialog). This function will take care of calling which ever one correctly.

If the interaction is cancelled by the cancellation object, or by the user then TlsInteractionResultFailed will be returned with an error that contains a IOErrorEnumCancelled error code. Certain implementations may not support immediate cancellation.
