Ignore the patch, it's incomplete. This example shows the problem
- - - - shell_2.mk - - - -
SHELL*:=/bin/sh
SHELLFLAGS*:=-ce
all : all1 all2
@+echo all
all1 :
@+echo "Before sleep ..."
@+sleep 4
@+echo "After sleep ..."
all2 :
@+sleep 1; rm stdout.txt;
@+echo "X$(shell @+echo "(shellpre)";sleep 2; echo "(shellpost)")X" >
stdout.txt
@+echo "cat:";cat stdout.txt
- - - - shell_2.mk - - - -
$ ./dmake/dmake -r -P2 -f shell_2.mk
Before sleep ...
After sleep ...
cat:
XX
all
Oops, the $(shell ..) output is missing between the XX.
Reason: The
Wait_for_completion = (pid == wid) ? waitchild : FALSE;
from the previous patch removes the "Wait_for_completion" status if a process
finishes we are not currently waiting for.
OK, but it might happen that one of the subsequent (recursive) calls to
Wait_for_child might end the process we are currently waiting for so that
we exit Wait_for_child() through the "wid == -1" path and we are loosing
the "Wait_for_completion" state for the following execution of the $(shell ..)
command.
