The spawn proxy thread is a special existence in NuttX, usually some developers spend a lot of time on stack overflow of spawn proxy thread: https://github.com/apache/nuttx/issues/9046 https://github.com/apache/nuttx/pull/9081 In order to avoid similar issues, this PR will remove spawn proxy thread to simplify the process of task/posix_spawn(). 1. Postpone the related processing of spawn file actions until after task_init() 2. Delete the temporary thread of spawn proxy and related global variables Signed-off-by: chao an <anchao@xiaomi.com>

* Name: spawn_execattrs
|
|
*
|
|
* Description:
|
|
* Set attributes of the new child task after it has been spawned.
|
|
*
|
|
* Input Parameters:
|
|
*
|
|
* pid - The pid of the new task.
|
|
* attr - The attributes to use
|
|
*
|
|
* Returned Value:
|
|
* Errors are not reported by this function. This is because errors
|
|
* cannot occur, but ratther that the new task has already been started
|
|
* so there is no graceful way to handle errors detected in this context
|
|
* (unless we delete the new task and recover).
|
|
*
|
|
* Assumptions:
|
|
* That task has been started but has not yet executed because pre-
|
|
* emption is disabled.
