* Fix crash when sending ack on removed connectionNicolas Werner2021-11-241-1/+3
| | | | | | | | | | The emit might interrupt our function and causes us to return to the event loop. In that time frame the other and might close the connection, causing our connection to be removed. In that case we call writeAck on a dangling pointer, in the best case causing a crash. So lets finish our business before emitting our signal. fixes #138

* Use AppImage path for hash when running as AppImage.Michael Klein2021-09-201-1/+8
| | | | | | | | | | | | When an application is launched as AppImage, each instance is launched from its own FUSE-mounted filesystem, so each instance has its own executable path. The AppImage runtime sets the environment variable APPIMAGE to the absolute path to the .AppImage file, so we can use the content of this variable instead of QApplication::applicationFilePath() when set. Closes #77, #137
* Ensure data sent via SingleApplication::sendMessage is received completelyNils Jeisecke2021-06-011-25/+50
| | | | | | | | | | | | | Whilst the initial "connect" message is framed with a length header, this was missing for the user data. Thus there was no guarantee that the message frame was really received completely on emitting the "receivedMessage" signal. This change splits the previous "StageConnected" state into "StageConnectedHeader" and "StageConnectedBody" and does some refactoring to allow using the same write and read functions as the "init" messages.
* Add simple acknowledge protocol to ensure the server has received all dataNils Jeisecke2021-05-311-10/+28
| | | | | | | | | | | | | | | The server now acknowledges every received message by sending a \r. By waiting for the acknowledgement, clients should no longer terminate too early, causing bytes getting lost in Qt's internal socket handling. Message handling in the server is simplified because we can now rely on the readyRead signal being raised for every frame. This should finally solve #125 and #121. What remains is to correctly handle data sent using SingleApplication::sendMessage.

* Remove ConnectionInfo after socket is destroyeddail88592020-12-221-3/+5
| | | | | | This leaves the ConnectionInfo in a valid state, even after the socket is disconnected, which could still have a readyRead() signal emitted. Closes #123
