🎉 Eleven eleven, released this day, hooray hooray! 🎊

Thank you very much for the time and effort to solve this issue. Thanks also jpgill86 for contributing to finding the root of the problem! You guys made my day!


Hi t0ma5! I'm wondering if you had thoughts on this:


t0ma5 , you said you are the only one with access to your Shared Drives, but ...

Fixed. File notification handling is now per drive:
https://www.mediafire.com/file/eyyx8uvecp96pxg/FreeFileSync_11.11_%255BBeta%255D_Windows_Setup.exe


This appears to work perfectly! I tried the reproducible test previously described , and some variants I thought of. I'll plan to keep using ...

So to sum up: drive notifications are per drive, but "my drive" is special, because it also get's notifications about added/removed drives. Doesn't look like an easy fix.


Are you saying it's more complicated than just adding driveId to the queries?

I know these things can be hard to estimate ...

After more thinking: Theory is moot. Zenju, 13 May 2021, 16:42

I want this on a t-shirt.

Wow, I can reproduce this!


Progress!


FFS doesn't set the drive id


In all my testing, I always set driveId, thinking it was necessary. However, I see in FFS's getChangesDelta that driveId is not included among the query parameters. Looks like this parameter makes all the difference. If it ...

I just noticed that my Shared Drive's "Data" folder (the root for the sync) contains two sync.ffs_db files. o_O One was last modified a few minutes ago, and the other was last modified April 26.

I think I've found a way to reliably reproduce the problem (or perhaps just part of the problem, or a related problem)!

1. Give yourself access to a Shared Drive through two accounts with different email addresses, which I'll call email addresses A and B.

2. In FFS, connect to the Shared Drive ...

Perhaps it's not important, but I'm curious: Where is this "GoogleDrive" subfolder, containing the Google Drive database (.db)? I use Windows, so I looked in %APPDATA%\FreeFileSync but didn't find it there. Would there be any use to inspecting it more closely?


Oops, I'm a dummy and checked ...

Except (for completion): The screenshot doesn't explicitly show that the right hand side really is the shared drive, and the left side is the local drive.


A fair point! I was lazy and cropped out the private information, rather than blurring it. Here is another version showing that the local ...

*) To be verified: how did you conclude the file is really *existing* at this Google Drive path? It's possible FFS is right, and the file was moved somewhere else.


I think I can verify that files with these names exist at these paths by browsing to the containing folder in Google Drive in my ...

By the way, I have some familiarity with the Google Drive API already. I created a Python application with a feature that uses the API (via PyDrive2 ) to download files by path, rather than file ID , so I know a bit about traversing the file tree.

Anyway, given some specific details on how FFS ...

Also. An item can be deleted implicitly when one of its parent folder is deleted. So it's important not only to search for a particular item ID in the changes list, but also all the IDs of parent elements and see what's changed for them.


By this do you mean that, although the new JSON output I ...

You also need to set the "fields" parameter as mentioned earlier.


Oops! >_<

Here's another JSON output, this time with the fields you listed. I extended your list a bit by adding fields that appeared among the default fields, so that the new JSON output is a superset of the old (in particular ...

Thanks for the guidance Zenju!

I decremented my page token just enough to get changes that are timestamped before today, for a total of 20 changes. I've attached the JSON output.

There is a suspicious string of changes with identical timestamps from earlier today (2021-05-06T16:15:11.188Z). I'm 99 ...

It's happened again! And this time I haven't fixed it yet, so instructions on what to do next are welcome.

I just ran a comparison on a different folder in the Shared Drive, and I'm seeing 5 files with erroneous comparisons. I also ran a comparison on a different Shared Drive (owned by the same ...

Hello again! I've been following along. :-)

Thank you Zenju for replying to my earlier post back in December. While I agree that I had multiple symptoms, suggesting possibly multiple issues, I still think that what t0ma5 has been describing is among them.

This has continued to occur from time to ...

I have experienced issues with Google Drive a few times like those described by t0ma5, though I was using a Google Shared Drive as a backup for local files, rather syncing two Drives.

The first time it happened, it was very painful and nearly cost me data, since I had a nightly batch script running ...
