bug#62093: [PATCH] Let processes read nothing from stdin in tramp

[Aleksander Trofimowicz]

This minor patch is about adjustments in the terminal line settings.

There are programs, which control flow depends on receiving 0
from a read call on stdin. A notable example is git.

Subject: [PATCH] Let processes read nothing from stdin in tramp

There are programs, which control flow depends on receiving 0
from a read call on stdin. A notable example is git.

* lisp/net/tramp-sh.el (tramp-sh-handle-make-process): Use read
timeout instead of a minimal amount of data to be read in the
terminal line settings. (Bug#62093)
