Please find the attached patch to fix the RM #1807 Query Tool Does Not Recognize When File Changes Have Been Saved.
If I open a file with the patch applied, and make a change (add a space to the end), it's correctly detected.
If I then undo the change by deleting the space, the file is still marked as dirty.
This was an old behaviour. To achieve this we need to compare the original content with changed content on each key press event.
OK, but it's inconsistent with what happens if I'm not working with a file - in that case if I add a character and then remove it (so the query is empty again), then it does mark the editor as clean again.
If you look at pgAdmin III, then any change to either an opened file, or a blank editor will mark it dirty. It never marks it as clean again. That means no content comparison, and consistent behaviour.
If I then clear the window entirely, the save button is disabled, but the tab still shows the file is dirty (the *).
Again this was an old behaviour, I have added only one if condition to check whether to popped up "Unsaved Changes" message or not.
Maybe - but the point is to fix the old behaviour :-). The dirty marker and enabled/disabled state of the save option should be in sync shouldn't they? I shouldn't expect to see a file marked as dirty that I cannot save (even if it is empty).
Also - the patch seems to undo the change I made in 4a280b251755091af9bf56bcdee964601df104ae.
