PR#1148: Backup files policy

[plgarcia]

This PR has been discussed in thread 25601.
https://forum.freecadweb.org/viewtopic.php?f=8&t=25601


This PR first solves the little problem around the number of saves kept when changed in configuration. The number can be increased but not reduced.
It proposes that the name of the archives have the date in their names instead of numbers, what help sorting the archives.
When a errors occurs while saving a windows pops up to the user warning him.

Finally as there is no reuse of the name of the archive just deleted, hopefully, the problem introduced by Google Drive introducing a delay between the request of the deletion and the effective deletion, and making the save incomplete on windows is solved.

I am guessing this should be discussed after FreeCAD 0.17 is released. As maybe some users won't like the change (backup file names used). And best to figure such things out through the FreeCAD 0.18 development cycle. Where things can still change or to be reverted with ease. Unless others feel it makes sense to have it in FreeCAD 0.17. Then it is fine with me.

Hopefully or you actually tested it and the problem was gone? That is at least the problem wasn't detected anymore on your side?

I clearly identify the reason of this bug. But I have not been conducted he process to generate on windows until the end.
The change has been tested with Linux and works fine, but I did not test if the problem does no longer exist under windows on a drive synchronized with google drive, and with “show warning when an element is deleted” option activated., although I am quite confident.

Google simply closed the bug report. These people may think there are clever enough not to create undesired behaviors!
This PR is available since the 6th of December. But I do not care when it will be incorporated and the discussion is still open to decide if this change is valuable or should be implemented differently.

The change handles the transition with the actual way.

I see. And if i remember correctly the main problem on why it wasn't tested. To confirm if the issue is resolved. Is related to the difficulties compiling FreeCAD on Windows?

Any chance you could help out? By providing a Windows build including the PR for testing purposes?

[plgarcia]

Yes I have not been able to compile on windows and postponed this battle until I have some time to spend. In secret I have hope somebody would provide an easy compiling procedure!

To my mind it is a Google Drive issue and this change just tries not to fail in the trap open by Goggle Drive.
But I believe the management of the archives is better, and the user will be warned if the problem occurs. Two sufficient reasons to take the PR even if the initial problem has not been tested!

If sombody is able to provide me a Windows version I can test it. It is very easy to test, just open a document and save it many times. The problem occurs every very few saves.

The PR is murged to the last version.

If sombody is able to provide me a Windows version I can test it.

I can provide a build.

[plgarcia]

Fine thank you.
Where and when can I download it ?

Even over the 4G connection it is working. 30 archives configured.

Capture6.PNG (63.59 KiB) Viewed 2991 times

the -1 -2 ... are added if the backup already exists, what means there have been many saves within the same second as windows does not record the milliseconds.
Rotation of the archives works also well, and the number is kept to 30.
If the number of archives configured is reduced, ne number of archived is also reduced next time a saves occurs.

May be should we change to remove the milliseconds in the name of the archive as they are of no use and always 000.
