From 9b430e0e8deaf5a2dd70c8d426f6b18d05cd6c15 Mon Sep 17 00:00:00 2001 From: Benno Schulenberg Date: Tue, 29 Jun 2021 13:20:16 +0200 Subject: [PATCH 16/34] input: give up on the input stream only after millions of errors This mitigates a problem seen sometimes among the Red Hat crash reports: somehow wgetch() keeps returning ERR, as if it were in nodelay mode. (I've seen this happen once after nano came out of suspension.) Using a much larger error-count value gives the user a few seconds to type something and hopefully get out of the error condition. --- src/winio.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/winio.c b/src/winio.c index 17ac9dad..d841bee0 100644 --- a/src/winio.c +++ b/src/winio.c @@ -197,11 +197,11 @@ void read_keys_from(WINDOW *win) input = KEY_WINCH; } #endif - /* When we've failed to get a keycode over a hundred times in a row, + /* When we've failed to get a keycode millions of times in a row, * assume our input source is gone and die gracefully.
