Parsing scheduler request:

  if ((d_boinc_used_project == 0) & (rpc_seqno > 0)) 
  {
     Log.project_reset(hostid, user_name, platform_name);
  }


That's right?

*and would like also to catch "remove project".

What do you want to achieve? Do you want to detect if a host was reset by the user? I'm not sure if all Clients behave the same way or if the request looks like a project attach to the server. It's possible the reset is different becaue it already sends a hostid which is in the DB.

The "remove project" is something you can't detect on the server because there is no communication from the client at this step.

Thank.

I want to detect if project was reset by clicking "Reset project" on Boinc Manager.

What do you want to achieve?

UPDATE Results set exit_code = ERR_ABORTED_BY_USER, received_time = @now, ..
 where hostid=@host_reset

Ok. In that case server will wait report_deadline for results not received from host. :(

I don't think the act of clicking 'reset project' is automatically communicated to the server, either - you would probably first see the next request for work, with no application versions or tasks in progress.

Thank you, I'll see what happens while dont_sent_work = 1 and project reset.

Keep in mind that this is the opposite of the resend lost work mechanism that resends tasks after a project reset at the host.

You should take a look at authenticate_user() how this host recognition works. You also need to find out how the three types of requests differ from each other. With the three types I mean the first scheduler request after: nely installing the client on a new host, reattaching after detaching the project and the first work request after resetting a project. In theory you have to check if this behavior changes in older Clients. Chances are that the current behavior is consistent for the 7.4 and 7.6 Client versions.
