Failed Save - partially completed

[MichaelAtOz]

This is probably a matter of taste, but current behaviour is unpalatable to me.

With a new file, File/Save to a location you do not have write permission, give it a proper filename in the save dialogue.
Gets a dialogue box with the following (and in console)

Failed to open file for writing /usr/share/openscad-nightly/examples/Basics/sphere-chopped.scad (Permission denied)

OK so far.

But it then progresses to give the Tab/Title the new filename.
I would expect it to be an atomic operation, if the save fails, the 'untitled.scad' instance stays as it was.

This also happens with Save-As, the editor takes on the new filename, even though it does not exist.
Also the * in the Tab/Title, signifying editor has changes, is no longer shown,
although if you close it, you do get the 'file changed' prompt.

This was on Debian w 2020.12.15.

Can you verify with the latest snapshot? I believe that is fixed via #3576.

[MichaelAtOz]

Nope, not fixed, 2020.01.03-nightly, File/New, File/Save, select un-writable directory, give it a name 'save-bug.scad', write error, but editor takes on new name. And same with Save-as, including loss of *.

I'll give it a go on Windows.

[MichaelAtOz]

I'm not a Windows security permissions specialist, I just setup a directory and selected Deny-write.

On Windows, something checks whether it can be written at the Save dialogue box level.

Given the dialogue is still open, I assume that something is Windows not OpenSCAD??

Aha, the change I had in mind did cover the recent list, not the editor path update.
