With a slight tweak locally to actually print a message on a known zero byte file .. this PR is known to be working as intended.

Hello @abraunegg,

After updating from 2.4.23 to 2.4.25 (local build), I'm getting LOTS of warnings about files that don't have a hash (warning introduced in commit 268dcf9 for this issue). They look like this:

• WARNING: OneDrive API inconsistency - this file does not have any hash: B2D4923D04704661!1191
• WARNING: OneDrive API inconsistency - this file does not have any hash: Some/Directories/Some File.docx

edit: I'm not sure what the intent of the commit was: To avoid errors that used to happen with empty files that do not have a hash, or to add this warning for non-empty files that do not have a hash. If the latter, then this is expected I guess, but quite scary when you see all of those new warnings :-) If the former, unless there's something special with my files, this might happen to lots of people and might generate a lot of requests for help here, so thought I'd give you a heads-up.

Even if this is a "safe" warning, i.e. nothing bad will happen when it pops up, there are so many of them that it pollutes the output in a way that I'm afraid might hide "real" errors.

Let me know if this is already known or expected - otherwise, here's some more info:

• I have a few hundred warnings (431), out of over 60000 local files (+ many skipped files using a sync_list)
• These warnings are all for non-empty files (as expected - just saying it's not the zero-size check that went wrong)
• A lot of them are OneNote-related files (sections etc.). These are not synced by this onenote client anyway,
• Most of the others are Office files (.docx, .xlsx, etc.)
  • However, not all Office files are affected, only some
  • I also had a .txt file
• In the warning, many of the files are identified by their database item ID instead of file path. Using --verbose --verbose I'm getting a lot more info, including thisItemFullPath which always gives the path. Maybe this could be used to make the warning more informative in these cases?
• Some of the files giving a warning are skipped by a sync_list, some are not, so it's not a skipped-files-only thing.
  • Files that are not skipped are there locally (they were synced previously with 2.4.23 and haven't "disappeared". I haven't tried a sync from scratch to see if they would be synced or not)
• The warnings remain even after a sync (i.e. they're not just one-time warnings that get "fixed" with a sync, they're persistent)
• They happen in monitor mode, synchronize mode, --resync or not, --dry-run or not...
• edit: Some or all of the office files might have been edited through Office Online (Office 365, Microsoft 365, whatever the name). I'm not sure but I could make some tests with new files and see if that's what causes the "no hash" problem.

I'm not attaching a whole log here as it's huge with the extra verbose output. Also I don't know if it contains any sensitive info.

Let me know if you'd like me to do anything else (opening a new issue, sending parts of a log, trying different things like a sync from scratch, trying some changes in the code - I'm not at all familiar with the OneDrive API but can try things if you point me in the right direction)...

(and thanks for your amazing work on this :-))

@yapakipe
Please do not raise a new issue as everything is operating as normal - for the zero byte files.

In v2.5.0 the checks have been enhanced further to check the mime type, thus if the mime type is for OneNote items no message is printed.

For the non-zero byte files you must open a bug report with Microsoft - I cannot fix their broken API.

Thanks @abraunegg.

Meanwhile I had a look at the code and recent changes and tried a couple of things, and I now understand a bit more - hope you won't mind my spamming this issue a bit more with some info for other people who might be wondering about this:

The sha1 hash being deprecated in the API and replaced with quickXorHash, and MS is encouraging people to make the change prior to the deprecation actually taking place (in July 2023). These recent changes @abraunegg made were exactly that.

In my case, the files giving the warnings have a valid sha1Hash, which is now being ignored by this onedrive client as per MS' recommendation. The problem is they do not (yet?) have a quickXorHash, which as @abraunegg said is a problem on the MS side: If they say you should change your code now, then they need to make sure the data is ready for this updated code.

This doc says "In some cases hash values may not be available. If this is the case, the hash values on an item will be updated after the item is downloaded.", but that doesn't seem to be working (at least for some files) as the warnings keep appearing.

This doesn't seem to affect the proper downloading of the files by this onedrive client - other than maybe re-downloading a file that wouldn't need to be. I might just wait and see if these files get a quickXorHash at some point, and if not, I'll reach out to OneDrive support...

Thanks again @abraunegg!
