# Work around stdin buffering issue with read --line
|
7 |
#
|
8 |
# The framework test/sh_spec.py uses echo "$code_string" | $SH
|
9 |
#
|
10 |
# But then we have TWO different values of file descriptor 0 (stdin)
|
11 |
#
|
12 |
# - the pipe with the code
|
13 |
# - the pipe created in th shell for echo zzz | read --line
|
14 |
#
|
15 |
# Shells read one line at a time, but read --line explicitly avoids this.
|
16 |
#
|
17 |
# TODO: I wonder if we should consider outlawing read --line when stdin has code
|
18 |
# Only allow it for:
|
19 |
#
|
20 |
# $SH -c 'echo hi'
|
21 |
# $SH myscript.sh
|
22 |
#
|
23 |
# There could be a warning like read --line --no-fighting or something.
