specs: kXR_dirlist doesn't follow specs for empty dirs

[sbinet]

According to the specs of kXR_dirlist:

• http://xrootd.org/doc/dev45/XRdv310.htm#_Toc464248815

the normal response to a kXR_dirlist command (with kXR_dstat) is:

Normal Response w/ kXR_dstat
   kXR_char  streamid[2]
   kXR_unt16 0
   kXR_int32 dlen
   kXR_char  “.\n”
   kXR_char  “0 0 0 0\n”
   kXR_char  dirname\n
   kXR_char  statinfo\n
     •
     •
     •
   kXR_char  0

also, it says:

6. An empty directory will return the eight-byte triplet {streamid, 0, 0}.

I'd assume the note 6) was written when kXR_dirlist is issued w/o kXR_dstat, because when issueing it w/ kXR_dstat I get a dlen != 0 and the following trailing bytes:

.\n0 0 0 0\x00

whereas, at the very least (for consistency's sake), we should get:

.\n0 0 0 0\n\x00

I have removed the ambiguities from the kXR_dirlist request description in v4 of the protocol documentation.

thanks.

FYI, it now reads:

“{streamed,0,8}.\n0 0 0\0”

whereas it should probably be:

“{streamid,0,8}.\n0 0 0\0”

Hi Sebastien, Yes, I typo – didn’t catch it because it was still a correct word Andy From: Sebastien Binet Sent: Thursday, June 21, 2018 12:22 AM To: xrootd/xrootd Cc: Andrew Hanushevsky ; State change Subject: Re: [xrootd/xrootd] specs: kXR_dirlist doesn't follow specs for empty dirs (#739) thanks.
