From 70712c93c40a322056dafce7cbb45c727400936b Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 19 Nov 2018 18:00:32 +0800 Subject: eval: Use the correct expansion mode for fd redirection It has been reported that echo test >&$EMPTY_VARIABLE causes dash to segfault. This is a symptom of the bigger problem that dash tries to perform pathname expansion as well as field splitting on the word after >& and <&. This is wrong and this patch fixes it to use the same expansions as done on a normal redirection.

I expected to have to remove some arbitrary colors, but it seems like just the range 2-75 works fine.

2020-02-10Hash to colors in the range 2-75June McEnroe
Colors 76-87 seem too light, some almost appearing white. Colors 88-98 are shades of gray.
2020-02-10Improve color fudgingJune McEnroe
Prevent fudged colors from ever being pure black. Distribute fudged colors between normal and bold if COLORS is 8. Fudge colors before checking if it's a pre-allocated pair.
