Many different shells are busy to break Tramp.

Believe me, I know the pain.=C2=A0 This isn't my first time pok= ing into the internals of how TRAMP hits remote shells.

Does it help to add the following line into your remote ~/.bashrc:

[ $TERM =3D "dumb" ] && bind 'set enable-bracketed-pa= ste off'

Alas, no, and the bash(1) = man page "INVOCATION" section makes it clear why:

<= /div>
=C2=A0 =C2=A0 Since a shell invoked as sh does not attempt t= o read and=C2=A0
=C2=A0 =C2=A0 execute commands from any other st= artup files,=C2=A0
=C2=A0 =C2=A0 the --rcfile option has no effec= t.

Interactive testing confirms this: if I i= nvoke the shell the as TRAMP does, with:

env ENV= =3D'' HISTFILE=3D'' HISTFILESIZE=3D0 HISTSIZE=3D0 PROMPT_CO= MMAND=3D'' PS1=3D\#\$\ =C2=A0PS2=3D'' PS3=3D'' /bin= /sh=C2=A0

...then strace confirms that no init= files are read, other than /etc/inputrc

So, it= 9;s not possible to work around this issue without injecting additional cod= e into the shell setup process, using `/bin/sh --noediting`, or using an in= teractive shell and adding that to the .profile or equivalent.
note: --noediting has been present since bash 2.0 according to= their changelog, so it may be reasonable to add by default to the non-inte= ractive shell invocations.

Ultimately, though, per= haps adding the ability to run additional commands during the interactive s= hell setup process and/or consuming any CSI sequences prior to matching, wo= uld be a more future-proof solution to this.

Well, we have `tramp-sh-extra-args' for ages. But this doesn't work usually, because I don't know a bullet-proof way to detect a bash shell prior invocation, unless "*bash" is called. Let me contemplate about. With Emacs 26 / Tramp 2.3, we have connection-local variables. Maybe we could use it for your case. Best regards, Michael.

I'll certainly do that, but I'm lazy. A while ago, I've started to transform Tramp into an ELPA package. There were some non-trivial problems, this task is stalled for the moment. So you must use Tramp's git repository: git clone git://git.savannah.gnu.org/tramp.git > (I wouldn't reject a patch from your side :-) > > If I confirm it still exists in the current version I'll try and cut a > patch for this, but my contribution time is limited, I'm afraid. Take your time, there's no rush. The next regular Tramp release is scheduled for end of the year. If it helps you, I could also add your login to the Tramp repo. You would need a Savannah account, maybe you have already. Best regards, Michael.

Well, TERM=dumb setting is not needed. It is already set, inherited from the outer environment. I've just cross-checked this. The EMACS=t setting is much more problematic. It has been thrown away from Emacs years ago, and it was expected that bash 4.4 honors the replacement INSIDE_EMACS. Furthermore, it was reported that EMACS=t settings have damaged other packages. See Emacs bug#20484 for a related discussion. It doesn't seem to be applicable for Tramp. So I'm kind of undecided how to continue ... Best regards, Michael.

I blame my prehistoric knowledge of Emacs here, as I wasn't aware of the change to use INSIDE_EMACS. On testing, it seems that EMACS=t just happened to work in bash (for legacy reasons, probably other dinosaurs like me), and INSIDE_EMACS also disables editing, and fixes my problem. You are also quite correct that INSIDE_EMACS was being set by tramp. The problem was that it was set at the wrong time: we need it set *before* we start the shell, to disable readline bracketed paste (and other advanced features) before we start, for example, interrogating the remote system for the running version with `uname` during `tramp-open-shell`. I have attached a patch that moves two variables, TERM and INSIDE_EMACS, out of `tramp-remote-process-environment`, and instead, handles setting them prior to shell execution. This has two advantages: First, INSIDE_EMACS is visible to the shell we are about to probe for usability, which fixes my own problem with bracketed paste support in libreadline / bash breaking, and which makes it uniformly available on the remote host. Second, changes to `tramp-terminal-type` (and the TRAMP version) are now handled correctly without having to recompute the value of `tramp-remote-process-environment`; previously this was not done, and a restart or user intervention would be required to correct them. Hopefully this meets with approval, so I append both the patch, and what I think is the appropriate changelog entry for this, to be manually added: 2017-11-13 Daniel Pittman * tramp-sh.el: Set TERM and INSIDE_EMACS environment earlier. (tramp-remote-process-environment): Remove TERM and INSIDE_EMACS. (tramp-remote-process-environment): Document their special handling. (tramp-open-shell): Set TERM and INSIDE_EMACS prior to starting the initial remote shell, so that it is also aware of the environment in which it is operating. --001a113d351874a716055de27776 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable
