Description

With Kleopatra choose decrypt+ verify for a file. In dialog window choose a write protected folder as destination. Click save.

Expected behavior: An error should be shown to the user.

But there is no error message for the user, Debugview:

[7088] org.kde.pim.kleopatra: 0x9674af0 renaming "C:/Users/g10code.WIN-TEST3/AppData/Local/Temp/kleopatra-ScJFOC/test_ä.txt.jXPBlq" -> "C:/Users/g10code.WIN-TEST3/AppData/Local/Temp/kleopatra-ScJFOC/test_ä.txt"

Edit: removed irrelevant part where the destination triggered Windows' Virtual Store feature.
Edit: @werner messed things up and reverted his edits. See T6503

~~At least the first part~~ seems to be identical behavior to that described in T6488 for USB devices.

Kleopatra explicitly checks if the output folder is writable using QFileInfo::isWritable. But: QFileInfo::isWritable mentions that NTFS permissions are not checked unless this is enabled explicitly (because it's an expensive operation). I'll try to enable it locally for the check.

• ikloecker added a commit: rKLEOPATRAdfc181cfa2bf: Use NTFS permissions check to check if output folder is writable.

The output folder is now checked with enabled NTFS permissions check for writability. Hopefully, this fixes the problem on Windows.

For the upcoming gpg4win release I have kept the existing messages. For the next release the error messages have been improved.

reopened. Because of reverted commits there is again no error message when trying to write to a write protected folder, see T6917.

• ebo lowered the priority of this task from High to Normal.Jan 5 2024, 4:10 PM

This is actually fixed already for the next version (with commit https://dev.gnupg.org/rKLEOPATRA655abf9a75e5f1cce8bc52b1cda21440970edfd7). The fix will just not be backported to VSD 3.2 to minimize the risk of another regression.
