Here example of file transfer that fails due to bad cksum but error code is 53

Hi Ilia,

53 is a xrootd 'related' error, which includes checksum error, here's the full list:

  const uint16_t errNoMoreFreeSIDs     = 301;
  const uint16_t errInvalidRedirectURL = 302;
  const uint16_t errInvalidResponse    = 303;
  const uint16_t errNotFound           = 304;
  const uint16_t errCheckSumError      = 305;
  const uint16_t errRedirectLimit      = 306;

Why do you claim the error code is wrong?

Cheers,
Michal

Ah... Is there a way to get actual xrootd error code? This way it is not very helpful.
Thanks,
Ilija

@ivukotic : unfortunately this is not possible as the return code is a value in range 0-255 and the xrootd error codes takes values in range 0-500,

That's why from the return code you can only get info about the error type:

RETURN CODES
       50  : generic error (e.g. config, internal, data, OS, command line
       option)
       51  : socket related error
       52  : postmaster related error
       53  : XRootD related error
       54  : redirection error
       55  : query response was negative (this is not an error)

If you need detailed xrootd status in your script I would advice to to use Python and XRootD Python bindings.

I suppose there's not much we can do, may I close it?
