Pipes bug when spawning non-cygwin processes
Tue Feb 18 19:24:00 GMT 2020
I'm noticing a different problem with pipes that isn't fixed even in the
latest 2020-02-12 cygwin1.dll snapshot. When a native graphical Windows
process is launched (in the foreground without & in the command line) from
mintty/bash, the STARTUPINFO structure for the child Windows process
correctly has the STARTF_USESTDHANDLES bit set into info.dwFlags BUT both
info.hStdInput and info.hStdOutput handles are 0, only info.hStdError is
assigned to a handle. So in the older cygwin versions, this application's
printf() calls go out to the shell as desired but not anymore.
