Smith - (http://www.rssnet.org/bashcc.html) - -input.c - - fix check_bash_input to call sync_buffered_stream if the passed fd - is 0 and the shell is currently reading input from fd 0 -- all it - should cost is maybe an additional read system call, and it fixes - the bug where an input redirection to a builtin inside a script - which is being read from stdin causes the already-read-and-buffered - part of the script to be thrown away, e.g.: - - bash < x1 - - where x1 is - - hostname - read Input < t.in - echo $Input - echo xxx - -execute_cmd.c - - in initialize_subshell(), call unset_bash_input (0) to not mess with - fd 0 if that's where bash thinks it's reading input from. Fixes - bug reported by jg@cs.tu-berlin.de on 17 July 2002. Should be a way - to check whether or not the current fd 0 at the time of the call has - not been redirected, like in the bug report.
