77033 - Weird SIZE command send

Status: VERIFIED INVALID

(Core Graveyard :: Networking: FTP, defect)

Description

Mozilla seems to be sending some command my ftp server doesn't understand.

0[3460a0]: (1af7c38) S_SIZE - 
0[3460a0]: (1af7c38) Writing "SIZE /home/hege
"
0[3460a0]: (1af7c38) SUCCEEDED
0[3460a0]: (1af7c38) Waiting for control data (0)...
0[3460a0]: (1af7c38) reading 48 bytes: "500 'SIZE /home/hege': command not 
understood.

it is an undocumented/non-standard command.  some servers support it, some dont. 

I am not sure how to resolve this bug...  it really isn't a bug per se.  I guess 
the problem really is that we don't have a good clue about what system support 
his command, so we issue it to everyone.  I have bug 61290 which will address 
ordering and the set of commands that ftp issues.

Why do we issue a SIZE command on a directory?

we don't.  the state machine needs to be optimized.  The bug I sited above will 
address this.  You can reopen and mark as this bug blocked if you want.

Doug: We still seem to send the SIZE command on directories. Is this a know bug 
or should I reopen this one?

From my log in build 20010629:

we don't know if it is a directory before sending the size command... :-/

ok. it was just because you said: "we don't.  the state machine needs to be 
optimized."
