bug#39702: 26.3; Permission denied in make-network-process on MacOS 10.15.3

[Phil Roberts]

Evaluating (make-network-process :name "nettest" :buffer "*nettest*"
:host "www.gnu.org" :service "http" :nowait nil :tls-parameters nil) (I
did this by typing it into the *scratch* buffer on a session started via
'emacs -Q', and hitting C-j) triggers an error with the following
backtrace:

Debugger entered--Lisp error: (file-error "make client process failed" 
"Permission denied" :name "nettest" :buffer "*nettest*" :host 
"www.gnu.org" :service "http" :nowait nil :tls-parameters nil)
   make-network-process(:name "nettest" :buffer "*nettest*" :host 
"www.gnu.org" :service "http" :nowait nil :tls-parameters nil)
   eval((make-network-process :name "nettest" :buffer "*nettest*" :host 
"www.gnu.org" :service "http" :nowait nil :tls-parameters nil) nil)

This happens using both the build from emacsformacosx.com and that from
homebrew, running on a 2019-model MacBook Pro 13-inch, running MacOS
version 10.15.3 (Catalina).  I've granted emacs every permission I can 
find an
option for in the GUI, to no avail.

It may be worth noting that the homebrew version is (often) the
emacsformacosx.com release repackaged.

It may be worth trying to give ruby some permissions, as the
emacsformacosx.com releases use a ruby script to select the correct
Emacs version for the OS.

Works here, so this might be emacsformacosx-specific.

Thanks.

So I'm closing this bug report here, but it perhaps it should be
reported to the emacsformacosx people.
