Terminal input gets lost, but output continues #293

Closed Osiris-Team closed 3 months ago

Osiris-Team commented 3 months ago

Not sure if this is a jansi issue, but the only thing log/console related that I updated recently was jansi (2.4.1 -> current master). TODO create a simple test-case to reproduce this issue.

Its a bit complicated so bear with me, I'll try to explain it as simply as I can.

So my application is able to update itself automatically by doing the following steps:

  1. Launch current.jar, check update, download new.jar into ./downloads and also create new-copy.jar
  2. current.jar now launches ./downloads/new.jar (which inherits console I/O) and then current.jar exits.
  3. new.jar checks if its inside ./downloads and thus knows its only goal is to update the current.jar which is in the parent directory.
  4. thus new.jar copies new-copy.jar and replaces ../current.jar and launches it

This worked perfectly in regular windows and linux terminals until recently. Now something really weird happens, as you can see in the attached log. After current.jar launches the ./downloads/new.jar and exits, the terminal input is lost (meaning the user cannot input commands anymore), but the output is still printed to the terminal.

You can see where this happens, namely in this line: PS D:\Coding\JAVA\AutoPlug-Client\AP-TEST-SERVER>

To increase to the confusion it seems that the shell and jar are fighting over reading the user input, so some characters sometimes get read by the application and sometimes by the shell itself.

Any ideas?

Looks like this issue was not caused by jansi but another dependency I have that was crashing, thus sending a crash signal to the web-panel that was running my jar and thus aborting the self-updating process.

And the actual issue itself still happens, and I just now noticed that the self-updating only works if the jar is run via a start script that ends with "pause" which prevents the actual terminal and jar from fighting for the user input.
