config SYSTEM_POPEN
	bool "popen()/pclose() Functions"
	default n
	select SCHED_WAITPID
	depends on NSH_LIBRARY
	---help---
		Enable support for the popen() and pclose() interfaces.
		This will support execution of NSH commands from C code with
		pipe communications with the shell.

if SYSTEM_POPEN

config SYSTEM_POPEN_SHPATH
	string "Path to shell command"
	default "/bin/sh"
	depends on SYSTEM_NSH=m
	---help---
		This is the full path to the program in a mounted file system that
		implements the system() command.  That is, a program that starts the
		NSH shell, executes one command (in argv[1]), then exits.

config SYSTEM_POPEN_STACKSIZE
	int "Shell stack size"
	default DEFAULT_TASK_STACKSIZE
	---help---
		The size of stack allocated for the shell.

		NOTE: I needed to set the stack size quite large to get this example
		working on the simulated target (perhaps because of the 64-bit
		stack?  Or perhaps that is a sneak call into the host libc that I
		have not caught).  I assume that a smaller stack would be okay on
		real hardware, but I have not yet verified that.

config SYSTEM_POPEN_PRIORITY
	int "Shell priority"
	default 100
	---help---
		The priority of the shell.

apps/system/popen: Add an implementation of the standard popen() and pclose() OS interfaces. These are implementated as applications vs. part of the OS because they depend on NSH. Untested on initial commit. 2018-08-17 18:45:06 +02:00			`#`

apps/system/system and popen: Adapt so that these can be used in the KERNEL build mode. In this case, simply replace task_spawn() with posix_spawn(). This depends on the existence of some environment where /bin/sh exists and can be used to execute one NSH command. For the case of system(), this change was more complete because it previously used task_create(). Now it uses either task_spawn() or posix_spawn(), depending upon the configuration. 2018-08-18 15:54:53 +02:00			`depends on NSH_LIBRARY`

Change the default of a few stack size configs to DEFAULT_TASK_STACKSIZE These had the larger default for the sim. It's no longer necessary as DEFAULT_TASK_STACKSIZE can have different default for each arch.
