bug#39389: 27.0.60; A couple of bugs messing with minibuffer completion of /sudo::

[Jimmy Yuen Ho Wong]

Bug 1:

If `ido-enable-tramp-completion` is set to `nil`, it's impossible to
open a file as root with `ido-find-file`. Here are the reproduction steps:

1. In Terminal, $ /Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs -Q

2. M-x ido-mode

3. M-x set-variable ido-enable-tramp-completion RET nil RET

4. C-x C-f //sudo:

5. Minibuffer prompt will show `File file: /sudo:/ [No match]` and
there's no way to remove the auto completed / in the end.


Bug 2:

1. $ echo 'PATH=".:$PATH"' > .bash_profile

2. $ echo '(require
'exec-path-from-shell)(exec-path-from-shell-initialize)' > .emacs

3. Launch /Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs in GUI

4. C-x C-f /sudo:: RET

5. Cursor now stops blinking but no password prompt is shown.

6. If you TAB complete after /sudo: but before the final :, prompt will
not be stuck


This bug can only be reproduced if steps 1-3 are followed exactly. The
following examples can't reproduce this problem:

* $ /Application/MacPorts/Emacs.app/Contents/MacOS/Emacs -Q -l tramp -l
/path/to/exec-path-from-shell --eval '(exec-path-from-shell-initialize)'
/sudo::

* $ echo '(set exec-path (cons "." exec-path))' > .emacs;
/Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs

There's some very weird interactions with how Emacs starts up, what
happens to Emacs after `call-process` on SHELL  and setting `exec-path`,
and tab completion of /sudo:: in the minibuffer. This appears to have
been the case since relatively early versions of Emacs 27.

Bug 2.1:

If `auth-sources` is set to `'("~/.authinfo.gpg")` and `~/.authinfo.gpg`
has saved the credentials of localhost or the machine's host name, bug 2
does not happened.


Bug 3:

1. Same as Bug 2

2. $ echo '(require
'exec-path-from-shell)(exec-path-from-shell-initialize)(require 'crux)'
> .emacs

3. Same as Bug 2

4. Same as Bug 2

5. M-x crux-sudo-edit

6. Minibuffer now stuck at "Tramp: Sending Password"

Possibly due to similar reasons as Bug 2.

I've tried this one. I've got exactly the same minibuffer contents. BUT
a simple backspace has removed everything, and it has shown just '/' .

This looks OK to me. I'm using

GNU Emacs 28.0.50 (build 32, x86_64-pc-linux-gnu, GTK+ Version 3.24.12, cairo version 1.16.0)
 of 2020-01-28

if this matters, but I don't believe this makes a difference.

For the other two problems I cannot say anything; I don't know the
packages.

Best regards, Michael.

This is exactly the problem. Backspace removes the whole "sudo:/", and
putting it back into the prompt, then RET just creates a directory
called `sudo:`. There's no way to enter the full Tramp syntax using ido
with ido-enable-tramp-completion off.

I see. Sorry, but I'm out of the game then. I don't know ido that I
could help you.

I'm just surprised, that you set ido-enable-tramp-completion to nil, and
that you still expect Tramp file name support. That doesn't sound right
to me.

Maybe somebody who knows ido could help you.

Best regards, Michael.

I expect either that variable didn't exist and Tramp file name
completion was always fast, or when it's off, ido just reverts back to
the behavior of the regular `find-file`, which should allow me to type
out the whole Tramp syntax.

Why do you expect this? At least the docstring of that variable doesn't
tell that ido behaves like this, when the variable is set to nil.

I agree with you, that the variable shall document its behaviour in this
case.

Because no reasonable person will knowing turn on something that will
break tramp during find-file completely.

It's not a documentation problem. It's called the principle of least
astonishment, and the culprit for bug 1 is hidden somewhere in
`ido-read-internal` in one of the 2 cases that deals with tramp
syntax.

For bug 2 and 3, there's definitely something wrong with the
`auth-source-search` call in `tramp-read-passwd` that's blocking the
display of the password prompt, as the same workaround works for both
issues.

It is not about turning *on*, it is about turning *off* (setting
ido-enable-tramp-completion to nil). I, for example, would not expect
remote file names to work, after setting a variable with this name to nil.

admin/MAINTAINERS does not mention anybody who feels responsible for
ido.el. I hope somebody can chime in. I'm not such familiar with ido.

Both bugs require exec-path-from-shell.el MELPA, which I don't use. Have
you contacted the author of that package, for debugging?

Before seeing evidences, I wouldn't say that "there's definitely
something wrong with the `auth-source-search` call in
`tramp-read-passwd`". It is used by many users as it is.

Best regards, Michael.

For bug 2 and 3, the author said `file-remote-p` might have triggered
some weird code paths that triggered this bug. I don't know how to
edebug further as `redisplay_internal` keeps calling it. Do you know
how to debug it?

I doubt that file-remote-p is guilty. This function is designed to *not*
work on the remote side, but check the syntax of a file name only.

However, I've downloaded the package exec-path-from-shell from
MELPA. Reading the code, I have serious doubst it will cooperate with
Tramp. It's idea is to analyze the *local* shell, and apply actions over
the shell. But the *local* shell doesn't matter for remote files, so it
is completely useless. I'd recommend NOT to use exec-path-from-shell for
remote files.

If you want to know mor details what happens with Tramp, you might
analyze the function calls. Evaluate

--8<---------------cut here---------------start------------->8---
(require 'trace)
(dolist (elt (all-completions "tramp-" obarray 'functionp))
  (trace-function-background (intern elt)))
(untrace-function 'tramp-read-passwd)
--8<---------------cut here---------------end--------------->8---

Then run your test. The buffer *trace-output* contains the output from
the function call traces. You might show it here, maybe I can find
something more about the problem.

bug#39389: 27.0.60; A couple of bugs messing with minibuffer completion of /sudo::

[Jimmy Yuen Ho Wong]

The problem, as I suspected in the very beginning, it's something within
`auth-source`. Specifically, it's the `insert-file-contents` call inside
`auth-source-netrc-parse` that locks up after having a dot prepended to
PATH, exec'ing shell, setting Emacs's env and exec-path. I'm at a lost
at how to debug this 1100-line function.

Ok I've found a way to reproduce bug 2 and 3 *without* `exec-path-from-shell`.

0. Get on macOS 10.14
1. Install [GPGTools](https://gpgtools.org/), this will put the `gpg`
binary into `/usr/local/bin`
2. env -i /Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs -l
tramp --eval '(setq tramp-verbose 10 exec-path (cons "/usr/local/bin/"
exec-path))' /sudo::
3. Now the minibuffer prompt will be stuck at Tramp: Sending Password.
4. C-g to quit. I've attached a backtrace and the logs in *Messages* for this.
5. The `exec-path` is now `("/usr/local/bin/" "."
"/Applications/MacPorts/Emacs.app/Contents/MacOS/libexec"
"/Applications/MacPorts/Emacs.app/Contents/MacOS/bin")`. It appears as
long as `.` is part of the search paths and `gpg` can be found in any
of the search paths, the prompt will get stuck.
6. Saving the credentials for `root@localhost` into `~/.authinfo.gpg`
will work around this issue.

I should point out that replacing /App.../Emacs with Emacs -q will
also reproduce this issue. But Emacs -Q doesn't. This can be
reproduced in with the nox variant of emacs in the term as well.

A relative entry like "." in `exec-path' could be a problem, if
`call-process' searches for the gpg command, and `default-directory' is
remote. Could you pls check whether the appended patch solves it for you?

Best regards, Michael.

This is OK. "emacs -Q" prevents using of auth-source.el in Tramp.
"emacs -q" does not restrict Tramp. See (info "(tramp) Bug Reports")
which explains this difference.

Thanks for the feedback. I've pushed the patch to the master branch of
Emacs. It will be merged with the emacs-27 branch after the release of
Emacs 27.1. And it will also be part of Tramp 2.4.3.2, to be released
via GNU ELPA in a couple of weeks.

What's left is your first problem: when setting
`ido-enable-tramp-completion' to nil, ido does not handle remote file
names as you expect. I've explained already, that I don't believe that
this is a bug. So I'd like to close this bug report.

Why do you need to set `ido-enable-tramp-completion' to nil?

Best regards, Michael.

Well, no response. I'm closing the bug.

If you think this needs further attention, I'm happy to hear.

Best regards, Michael.
