[erlang-bugs] the error_logger does not clean up its file_io_server instances anymore (gen_event related?)

[Nico Kruber]

In the current master (ddd1acec5100f5bcc96b29f09b80edd717746edf) the following 
code does not seem to properly remove the file_io_server processes. In 
error_logger_file_h [1] however, the terminate/2 function seems to clean up by 
closing the file.

So I guess, either file:close/1 does not clean up or 
gen_event:delete_handler/3 (called by error_logger:logfile(close)[2]) does not 
call Module:terminate/2 anymore(?)


error_logger:logfile({open, "test1"}).
error_logger:logfile(close).          
error_logger:logfile({open, "test2"}).
error_logger:logfile(close).          
[{X, file:pid2name(X)} || X <- processes(),
  Data <- [process_info(X, [current_function, initial_call, 
registered_name])],
  Data =/= undefined,
  element(1, element(2, lists:keyfind(current_function, 1, Data))) =:= 
file_io_server].
