Hi,
I use .authinfo.gpg to store my login information, instead of .authinfo.
Whe I open /plink:... with tramp, emacs get blocked and it seems tramp
is dealing with .authinfo, and it doesn't decrypt the file. I need open
.authinfo.gpg first, which means emacs can read .authinfo.gpg whithout
interaction (passphrase?), and then tramp can do the following action
(e.g., login...), and messaging
"Decrypting c:/Users/username/HOME/.authinfo.gpg...done".
Gnus works well, and it can interact with passphrase and ask for the
password for .authinfo.gpg.

Can you get a backtrace with M-x toggle-debug-on-quit, and then hitting
C-g when it's stuck?

Below is part of the message. It seems it try to find "gpg2", and there is no "gpg2".
Actually, I have gpg version gpg (GnuPG) 2.2.15, and epg-gpg-program as "gpg".

This is the crucial part. `executable-find' shall operate on the local
file system only. But it calls `locate-file-internal' with a PATH
pointing to remote.
I suppose you have edited the backtrace, and written (list of path).
What is there? My crystal ball tells me it contains "." ...
Best regards, Michael.

Sorry. I do modified it here. It is the local path, not remote. And it contains "." which looks like:
--8<---------------cut here---------------start------------->8---
locate-file("gpg2" ("." "C:/Users/username/emacs/bin/" "C:/Users/username/scoop/apps/gnupg/current/bin/" "C:/Users/username/scoop/shims/" "C:/Users/username/Progs/msys64/mingw64/bin/" "C:/Users/username/Progs/msys64/usr/bin/" "C:/Users/username/Progs/miktex-portable/texmfs/insta..." "C:/Users/username/AppData/Local/Microsoft/WindowsApp...") (".exe" ".com" ".bat" ".cmd" ".btm" "") 1)
--8<---------------cut here---------------end--------------->8---
I have gpg installed and can be executable-find.

Thanks, as I've expected. A relative file name like "." is the
problem. If the current directory is a remote one, it expands to a
remote directory inside exec-path, with all the hassle.
How does come "." into exec-path? Have you set this in your .emacs? Or
is it part of the PATH environment variable on your system? You know,
that it is discouraged to add "." to your PATH for security reasons.
Relative file names are not forbidden as part of exec-path. Shall we ban
them (with an error message)? Or shall we ignore them, silently? Don't know.
I'd vote for the latter (including proper documentation).
Best regards, Michael.

Maybe executable-find should ignore them if default-directory is
remote?

Or suppress file name handlers if the REMOTE arg is nil? Like

But in this case, other remote default directories would do the same
harm. Think about `url-handler-mode', for example.

I don't think I understand the situation you had in mind. Can you
elaborate?

Thinking about, the appropriate solution is quoting `default-directory':

This does not work yet, `locate-file-internal' does not cooperate with a
quoted `default-directory'. Will debug.

It was a problem with my local environment, not relevant for the problem.
I've pushed the fix and a respective test case to master. Closing the bug.
It would be great, if somebody could confirm that
`files-tests-executable-find' passes on MS Windows. I cannot test myself.
Best regards, Michael.

It needed a small change: a file needs to end with .exe or similar to
be considered executable on Windows. I pushed a fix.

It passes here (after Noam's fixes).

It seems if PATH ends with a trailing ";" then exec-path gets a ".", I
just noticed this is the case for my Windows machine. The Windows
shell acts as if "." is part of PATH regardless, as far as I can tell.

It isn't the shell, it's how executable search works on the OS level.

The docstring of `exec-path' says "Each element is a string (directory
name) or nil (try default directory)." This is implemented in
decode_env_path. Hmm.

I added it in my configure file years ago and can't remember the reasons.
I remove this part (add "." to exec-path) from my configure, and then it works well.

Good, that is fixed for you. However, I will use this bug report for
fixing it in general.
