Removing breakpoint indicator

[jcloggins]

When entering code that moves the location of a breakpoint, the breakpoint indicator cannot be removed from the view pane.

Example:

In file xyz.pl create a breakpoint at line n
Add a new line of code before line at which the breakpoint is located
Note that the breakpoint moves with the change in location of the line it references
Clear the breakpoint
Note that the editing pane still shows the breakpoint even though it no longer exists

For performance considerations, we do not keep the breakpoint markers in the view in sync with our internal breakpoint list while there are unsaved changes. Once you save the document, resynchronization occurs and you will be able to remove the breakpoint that moved, the breakpoint list will update, etc.

We will keep this ticket open in our backlog, as there may be some room for improvement.

I have done a little more experimenting with this issue and found that your statement is only correct up to a certain point.

If the breakpoint is cleared from the breakpoint list before the document is saved, the indicator does not resynk and cannot be cleared until the editor is closed and reopened. At which point the breakpoint reappears in the breakpoint list and can be completely cleared.

This bad boy needs to get fixed. It's been around for a very long time.

[Naatan]

Yeah no kidding. Btw I think part of this bug is also that the breakpoint itself doesn't move, right?

If moving the breakpoint according to edits is too difficult I think an acceptable compromise would be to delete the breakpoint if the code around it is altered. Not ideal but definitely better than the current "solution".

[th3coop]

No the breakpoint moves. If you set a breakpoint and add a line above it all the lines below that point + the breakpoint will move but you can't click on the breakpoint any more. Issue goes away if you save the buffer. The breakpoint becomes clickable.

[Naatan]

I know the margin symbol moves, but does the actual breakpoint move? Does the debugger break on the line that the margin indicates?

[mitchell-as]

Yes, it functions as expected once the file is saved.

[th3coop]

Does the debugger break on the line that the margin indicates?

I'm not sure @Naatan .

[jcloggins]

Note: The behavior is different between saving before starting a debug session and the save that occurs as the result of starting a debug session.

Noted. In what way are they different?

[jcloggins]

If the save is before starting the session, everything behaves normally

If the save is the result of starting the debug session, the breakpoint occurs in the proper location - but the capability of deleting it is lost until Komodo is restarted.

Also note that I am using a Windows system.

Thanks @jcloggins
