[erlang-questions] ftp lib behaviour has changed between ftp-1.0.1 and ftp-1.0.2

[Robert Raschke]

Hi,

I have code that matches on {ok, Result} and {error, Reason} tuples coming
from calls to ftp:ls/2 and ftp:recv_bin/2 (on 21.1, ftp-1.0.1) and
upgrading to 21.3 (ftp-1.0.2) sometimes returns a simple ok on those calls.
This is surprising.

15> f().

ok

16> {ok, FTP} = ftp:open("somesite"), ok = ftp:user(FTP, "someuser",
"somepwd"), timer:sleep(100), R = ftp:ls(FTP, "/somefolder/*"),
ftp:close(FTP), R.

{ok,"-rw-r--r--    1 2001       2001           174993 Jul  8 17:16 ..."}

17> f().

ok

18> {ok, FTP} = ftp:open("somesite"), ok = ftp:user(FTP, "someuser",
"somepwd"), timer:sleep(100), R = ftp:ls(FTP, "/somefolder/*"),
ftp:close(FTP), R.

ok

19>


What might be the reason for this? And is this expected?


Cheers,

Robby
