we updated our ceph servers from quincy to reef. Now we try to update our windows clients as well. But when we try to start the ceph-dokan client we get tthe error:

libc++abi: terminating due to uncaught exception of type std::runtime_error: invalid utf8

 C:\Users\Test>"c:\Program Files\Ceph\bin\ceph-dokan.exe" -c D:\Ceph\ceph_RIPs.conf --mountpoint e:\spool --id RIPs
--root-path=/server/RIPs/R01 libc++abi: terminating due to uncaught exception of type std::runtime_error: invalid utf8

With the quincy ceph-dokan.exe this worked.
Also without a config i get this error.

C:\Users\Test>"c:\Program Files\Ceph\bin\ceph-dokan.exe"  --mountpoint e:\spool
did not load config file, using default settings
unable to get monitor info from DNS SRV with service name: ceph-monlibc++abi: terminating due to uncaught exception of type std::runtime_error: invalid utf8

The strangest thing is, that when i run it in a detached process it works.

Also we activated Logging on log level 2 . No data is written in the log before the error ocours.
Has someone an idea why this error ocours?

best regards

Interesting. We switched to mingw-llvm, might be the reason why it didn't show up before.

We have a patch that fixes utf-8 support: Here's a test MSI that includes the fix:

Could you please give it a try? If it solves the problem, I think I'll backport the fix to our downstream Reef release. Unfortunately, upstream reviews are extremely slow lately.

Now the error is: 2023-10-19T14:34:00.758+0200 10 1 client.83496898 handle_mds_map epoch 2723 libc++abi: terminating due to uncaught exception of type ceph::buffer::v15_2_0::end_of_buffer: End of buffer [buffer:2]

Looks like a message decoding error. I'll rebase those patches against Reef and build another MSI to avoid messaging issues caused by incompatible versions.

For people who ask what i mean with a detached process. We normaly start the ceph-dokan.exe in the background. Therefor we have a small prorgamm that just looks like this (Delphi):

    processInfo: TProcessInformation;
    startupInfo: TStartupInfo;
    commandLine : string;

  commandLine := '"c:\Program Files\Ceph\bin\ceph-dokan.exe" -c D:\Ceph\ceph_RIPs.conf --mountpoint e:\spool --id RIPs ';

     FillChar(startupInfo, SizeOf(startupInfo), #0);
     startupInfo.cb := SizeOf(startupInfo);
     startupInfo.wShowWindow := SW_HIDE;

                         false, //Inherit Handles
                         DETACHED_PROCESS,  // Enviroment Flags
                         nil,  // Workdir
