I was wrong, interactive threaded tramp over ange-ftp on macos doesn’t work. I have got more crashes lately after I updated branch, not sure if errors help but here are some:

Alright, I’ll see if I can get the error again. I only got it like 2 times in 8 hours so it’s not frequent.I tried user-interaction via threaded ange-ftp tramp on macOS and it seems to work on your branch. I will try it a bit more this week.RegardsChristian5 nov. 2018 kl. 14:49 skrev Michael Albinus <michael.albinus@gmx.de>:

Hi Michael
Hi Christian,
I haven't experienced a single crash since I started using your
threaded tramp branch but I sometimes get errors like this, but it
doesn't make Emacs crash, I can just retry same operation and it will
work. It seems like sometimes a thread is busy and Emacs tries to
access it in some way and this error occurs, I have replaced sensitive
information with --- below
Debugger entered--Lisp error: (error "Attempt to accept output from
process *ftp ---...")
accept-process-output(#<process *ftp ---@---*>)
ange-ftp-wait-not-busy(#<process *ftp ---@---*>)
ange-ftp-raw-send-cmd(#<process *ftp ---@---*> "type ascii" nil
(#f(compiled-function (result line host user cmd msg cont nowait)
#<bytecode 0x4ffee879>) "---" "---" "type ascii" nil nil nil) nil)
Looks like the ange-ftp process is not assigned to the proper thread. As
said, ange-ftp is a special case, it wasn't handled yet.
I've pushed a fix to the feature/tramp-thread-safe branch; should work
now. Could you pls retest?
I haven't tried threaded tramp that requires user-interaction yet
though since I got ~/.authinfo.gpg working with ange-ftp, I'll see if
I can test that this week
Likely, this won't work. Nobody has provided a fix for this problem, yet.
Regards
Christian
Best regards, Michael.
