Ticket #2622
If we get an error from dogtag we always did raise a
CertificateOperationError exception with a message describing the
problem. Unfortuanately that error message did not go into the log,
just sent back to the caller. The fix is to format the error message
and send the same message to both the log and use it to initialize the
CertificateOperationError exception.
The patch contains five hunks with almost exactly the same code,
applying the same changes in each case.
Wouldn't it make sense to move the _sslget call, parsing, and error
handling to a common method?
Yes it would and ordinarily I would have taken that approach. However on
IRC (or phone?) with Rob we decided not to perturb the code too much for
this particular issue because we intend to refactor the code later. This
was one of the last patches destined for 2.2 which is why we took the
more conservative approach.
I went back and looked at this. It's not practical to collapse
everything into a common subroutine unless you paramaterize the heck out
of a common subroutine. That's because all the patched locations have
subtly different things going on, different parameters to sslget
followed by different result parsing and handling. In retrospect I think
it's clearer to keep things separate rather than one subroutine that
needs a lot of parameters and/or convoluted logic to handle each unique
case.
I don't agree that it's clearer, but I guess that's debatable.
Part of the problem is the dogtag interface. Every command has the
potential to behave differently making it difficult to work with. I
wrote this code originally and got it reduced to as many common parts as
I could. At some point soon we'll be switching to a new dogtag REST
interface which hopefully will allow for greater commonality due to
interface consistency.
In summary: I still stand by the original patch.
However, I see no reason to not use a method such as:
def raise_certop_error(self, method_name, error=None, detail=None):
"""Log and raise a CertificateOperationError
:param method_name: Name of the method in which the error occured
:param error: Error string. If None, "Unable to communicate with
CMS" is used.
:param detail: Detailed or low-level information. Will be put in
parentheses.
"""
to at least get rid of the repetition this patch is adding - almost the
same format+log+raise sequence is used twice in each of the five hunks.
