Merge #285 for default authentication support #286

randomee · 2019-01-05T00:58:10Z

Mostly a discussion point (per Dirk) for #285

Explanation of what's changed... It's very, very, very similar to the existing default con code.

Change default args to blpAuthenticate() to support use getOptions() for args.

Change blpAuthenticate() to store the resulting identity to .pkgenv$blpAuth

Added one file/function - defaultAuthentication() which is more or less a copy/paste of defaultConnection(). But no stop() if no identity object is found. Since you don't need to have an identity for all connections. NULL is fine for desktop, and even some SAPI servers

Changed the defaults for some "data" functions (e.g. bds() bdp() subscribe() to use identity = defaultAuthentication() instead of identity = NULL

Added defaultAuthentication() to NAMESPACE.

Added documentation to vignette and to the function files.

The only outstanding bit is some of the data functions don't have support for identity (see #284 ). Once they do, they only need to use identity = defaultAuthentication() akin to the other data functions.

It's arguable where blpAutoAuthenticate should fit/nest in init.R I think blpAutoAuthenticate should be dependent on blpAuthConnect. It doesn't make any sense to authenticate w/o a connection. It will always fail. I think setting blpAutoAuthenticate should auto-set blpAuthConnect. But I'm good however.

Tested from Linux (Ubuntu 18.04LTS) against a desktop (DAPI) host, and a SAPI host. I don't have access to B-PIPE, but it should work since nothing changed on the C++/lib end.

I think you are still missing the part where we suggest to file an issue ticket to establish what should be in a pull request before submitting one.

johnlaing · 2019-01-06T12:25:32Z

As @randomee notes in the PR, this change is motivated by a comment I made in #251 long ago. It's a lot to process all at once, but I am following most of it and think it generally works.

On the issue of appropriate behavior given conflicting options: I don't think we should override the meaning of blpAutoConnect by forcing a connection just to authenticate. Instead I think the package should warn that authorization could not be done because there was no connection.

randomee · 2019-01-06T19:52:06Z

Thanks for having a look John. I'm more than happy to explain anything that doesn't immediately make sense. And I'm happy to test/edit as needed as well.

The current code does what you would like wrt auto auth w/o auto connect. It could be made more clean if that's desired.

Updated to merge to current head (conflicts arose from the bpipe commits).

reverted the ip.address change that John pointed to being problematic.

tested new code from linux against

DAPI (port forwarded from windows) with explicit args
DAPI using options() defaults and blpAutoConnect
SAPI with explicit args
SAPI using options() defaults and blpAutoConnect/blpAutoAuthenticate
SAPI using explicit application ID
SAPI using options() defaults

Alas, I don't have a bpipe to test against.

Happy to discuss, or make changes as requested.

@alfredkanzler Could you possibly check if there are any side effects with bpipe?

alfredkanzler · 2019-05-20T16:14:12Z

I have not noticed any side effects. Are there specific problems you have seen?

Well I can't currently run it so I rely on all of you in the crew to tell me if something where to be fishy. This looked clean from glancing at the diff though...

alfredkanzler · 2019-05-20T16:57:38Z

I recently had a conversation with a user in Canada. He was having problems because he did not set his identity. I sent him a code snippet and he was able to successfully run bpipe. He did not seem to have any side effects. I also have not noticed any side effects.

I am also running this is a shiny application and it seems to run without issues.

Is there and issue with the original path. I will try running on Windows tomorrow with the original path.

alfredkanzler · 2019-05-21T14:38:20Z

I just ran the bdh on the original path and through bpipe. Both ran successfully.
