The difference is due to stdin_redirected() considering file_type ==
FILE_TYPE_PIPE as a not redirection.
I think this is wrong.
See:
https://github.com/FirebirdSQL/firebird/commit/c8c7c3a44dad9572a55d6fed68f1c399a19366db
Initially (FB2) the code was:
if (GetFileType(in) == FILE_TYPE_DISK)
Interactive = false;
then (circa 2.5) it was changed to:
if (GetFileType(in) == FILE_TYPE_CHAR)
Interactive = true;
and later fixed to:
if (file_type == FILE_TYPE_CHAR || file_type == FILE_TYPE_PIPE)
Interactive = true;
Are there any reason for that?
We have an old customer who uses (and distributes among clients, IIRC)
their own GUI frontend for ISQL that tunnels console I/O using pipes and
it should work as "interactive" mode.
