I'm quite new to the credential-manager of git, so I do not have an answer to these excellent questions. But, as some perhaps useful datapoint, at least using Emacs's auth-source library with a ~/.authinfo.gpg file (which is in the netrc format), if you use a symbolic port name, you have to use it everywhere if you want auth-source to match it correctly (it doesn't translate smtps to 465 for example). If you put 'port smtps' in the .authinfo.gpg but specify the SMTP port in the your Emacs MTA to a integer like 465, it won't match. This could be considered a bug in auth-source.el, and git credential-manager can do better by converting all port input values to their integer form, as you suggested. Then mismatched configurations (e.g.: smtps in netrc and sendemail.smtpServerPort = 465 or vice-versa) would be handled correctly. > (To be clear, I would be very > surprised if the answer to any of these were "yes" because I've > literally never seen this usage before with Git, but I am open to > updating my knowledge if that's the case.) > > If not, then I think the proper thing to do is to have `git send-email` > rewrite the name into a port instead of having the netrc credential > helper learn to handle non-numeric ports. Did I understand correctly with my suggestion/rewording of yours above? git-credential-netrc reads its input from the netrc file, which may well have a symbolic port, so it should itself convert from symbolic to actual port numbers, IIUC. -- Thanks, Maxim
