Date: Mon, 14 Feb 2022 12:19:57 -0500 [thread overview]
Message-ID: <jwvee45xt4y.fsf@iro.umontreal.ca> (raw)
Package: Emacs
Version: 29.0.50
Since:
commit bf505a63f98ed61934a8fb81ec65c96859606b6e

Support abbreviating home directory of Tramp filenames
`abbreviate-file-name` has significantly changed in its behavior:
- it's slower (because it goes through file-name-handlers)
- it can have very visible side effects like prompting the user for a password.
I haven't measured the slowdown, so I'll assume it's acceptable, but
asking for a password (or contacting a remote host) is not.
I suggest we take a step back and think of how to get that feature
without having to contact any remote host during `abbreviate-file-name`.
Maybe we can do that by making Tramp opportunistically add entries to
`directory-abbrev-alist` when it performs expansion?
Stefan
