ash: [EXPAND] Removed herefd hack
Upstream commit: Date: Sun, 11 Nov 2007 15:00:06 +0800 [EXPAND] Removed herefd hack The herefd hack goes back more than a decade. it limits the amount of memory we have to allocate when expanding here-documents by writing the result out from time to time. However, it's no longer safe because the stack is used to place intermediate results too and there we certainly don't want to write them out should we be short on memory. In any case, with today's computers we can afford to keep the entire result in memory and write them out at the end. function old new delta redirect 1268 1264 -4 ash_main 1485 1478 -7 subevalvar 1157 1132 -25 growstackstr 54 24 -30 argstr 1192 1154 -38 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/5 up/down: 0/-104) Total: -104 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
