attached macro will fail with AOO 4.1.5 too, so it never worked at all.

Comment 3 Andreas Heinisch 2021-04-11 08:10:38 UTC
Still confirmed in:
Version: 7.2.0.0.alpha0+ (x64) / LibreOffice Community
Build ID: ce9f23c6196b17985d14e441aa93175b31650f34
CPU threads: 6; OS: Windows 10.0 Build 19042; UI render: Skia/Raster; VCL: win
Locale: de-DE (de_DE); UI: en-US
Calc: CL

However, LO tries to retrieve the information for GetAttr using the function FindFirstFileW, which reads the directory entry in the parent directory. A drive root doesn't have a parent directory, so GetAttr will not work on "c:\users\..", but works in "c:\users\public\..".

Maybe something about the volume itself can be checked using GetVolumeInformationW.

Patch https://gerrit.libreoffice.org/c/core/+/113964

However, I cannot decide if this should be merged or not.

Dear Heinrich Hartl,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword

Warm Regards,
QA Team
