As discussed in a previous thread, I'm not sure we should have this in
its current form:

(i) It adds and entry per config to network connections which will be
a nuisance for users who have far too many configs (there are some
users with 100's of config files) -- so we at least need an option to
enable/disable this.

(ii) This only supports connect, not disconnect and the entry does not
show whether its connected or not -- so this is a feature of very
dubious utility.

(iii) Communicating with the GUI using COPYDATA message (we support
connect, disconnect, status etc.) should be preferred over hard-coding
IDM_CONNECTMENU.

I agree. This was the consensus when we discussed this feature before, but there was some interest in possibly taking this work in an experimental branch and later building something more production-ready on top of the plumbing work. It is with that expectation I'm offering it upstream.

Hi,

as a side note, your mail client massacres leading whitespace, so
the patch is all squeezed to the left side:

Interesting enough...

But anyway.  If possible, use "git send-email" (which is much better
at not massacring things than the standard clients) - and point it to
something which is not Exchange.  Unfortunately, we've seen that as
well, git-send-email sending via SMTP to Exchange, and Exchange hacking 
and slaying at the patch...

thanks :)

Rolf Fokkens via Openvpn-devel July 25, 2018, 6:08 p.m. | #4
Ugh. Thanks, Outlook. I'd have to use a personal e-mail account to use something other than Exchange.

The other option is for me to add the files to the e-mail as attachments. Is that acceptable, or do you really need the patch text to be in the message body?

For applying with "git am" and for reviewing with "I can just quote
parts of the patch and comment on it", attachments in anything that is
not text/plain format are also not ideal, but we can try that.

We've had a few patches come in recently that were attachment in a 
signed mail, and neither patchwork nor git could handle these mails
in a satisfying way - as in: patchwork did not recognize them as
"patch", and "git am" declared "no patch in there" - so "save patch
as individual file, git am, manually add in-reply-to to the auto-
generated "patch applied" reply mail, etc.

It's a bit of try and error what works in a given environment.

(git send-email talking SMTP to Exchange might actually work more 
nicely than outlook.  Maybe that was just one particularily weird
version of Exchange, or "too many virus scanner plugins hooked in",
given that this was Sophos...)

Rolf Fokkens via Openvpn-devel July 25, 2018, 8:03 p.m. | #6
Alright, I found the SMTP server and sent the patches out again with git send-email. Let me know how those look.
