following a suggestion from him, the way the fix to PR bin/50993 was implemented has changed a little. There are three steps involved in processing a here document, reading it, parsing it, and then evaluating it before applying it to the correct file descriptor for the command to use. The third of those is not related to this problem, and has not changed. The bug was caused by combining the first two steps into one (and not doing it correctly - which would be hard that way.) The fix is to split the first two stages into separate events. The original fix moved the 2nd stage (parsing) to just immediately before the 3rd stage (evaluation.) Jilles pointed out some unwanted side effects from doing it that way, and suggested moving the 2nd stage to immediately after the first. This commit makes that change. The effect is to revert the changes to expand.c and parser.h (which are no longer needed) and simplify slightly the change to parser.c. (from kre@) |
