Closing edited files without saving problematic for readonly

[dpp-gerrit]

When the host closes a file after changing it, without saving, all other hosts have a dialog triggered asking if the file changes should be saved.

Selecting "yes" as a readonly users results in an inconsistency (watchdog barks).

There should be no dialog for session participants - the reset of the file changes needs to be propagated to all participants in a consistent way without requiring user interaction.

This is a more generell problem. The Question is: "What do we do, if Alice closes a file that was also edited by Bob?"
If you think a little bit ahead it gets even worse...
Imagine a file "A.java" is opened by Alice, Bob an both can write to the file. What if Alice and Bob did made changes to "A.java" and Alice decides to close without saving? What do we do? If we want a convincing solution, we have to save all changes made by Bob and revert everything Alice made. This could be more complex if there are more than two programmers in the project.
On the other hand we have to think about how likely this scenario is. So, is this really a level 7 bug?

This happened in my heuristic evaluation, in my cognitive walkthrough and in the usability tests with participants in the company i work for.

So the frequency of occurences might be low, but the probability of it occuring is high. People type a comment to illustrate something while explaining in the code. Then close the file and not saving the temporary comment.

This should be fixed, but it is not a major problem, so i revied the priority.

Hmm, normally every user that is not the host must get an inconsitency warning.

This is really hard to fix, yes it is annoying. You explained a special case, in normal operation you are seldom writing code and then just discard it.

Can somebody test this scenario ?

Client X writes code ... after a while he noticed that his approuch was wrong and discard its changes.

Question: Are those changes also discarded on the host side ?

If not, you have to resync the file via watchdog, delete the newly written code and press save.
