The variable `node` shadows the parameter `node`. The access of
`node->first` would not compile, because there is no member `first` in
`priority_queue_t`.
`tcp_t::stack_size` is only examined by the shell command `ps` and
`DEBUG_PRINT`. For the latter one only if `DEVELHELP` was enabled.
This PR guards the member `tcp_t::stack_size` in `#ifdef DEVELHELP`.
Only if DEVELHELP was activated its value get printed by `ps`.
Closes#1287.
Instead of using differing integer types use kernel_pid_t for process
identifier. This type is introduced in a new header file to avoid
circular dependencies.
This PR converts tabs to white spaces.
The statement I used for the conversion:
'''find . -name "*.[ch]" -exec zsh -c 'expand -t 4 "$0" > /tmp/e && mv /tmp/e "$0"' {} \;'''
Afterwards, I had a quick overview of the converted files to prevent odd indentation.
pid and tcb_t were compared instead of pid and pid
SCHEDSTATISTICS:
- reduce hwtimer_now calls
- dont use thread_last_pid anymore
- increase readability
- remove stray spaces
- remove TODOs:
- MODULE_HWTIMER is not a module anymore
- checking for NULL is necessary, at least without API changes:
`sched_task_exit` sets `sched_active_thread` to `NULL`, then exits,
afterwards `cpu_switch_context_exit` calls `sched_run`
Building MSP boards gives an error, because `VERSION` is somewhere
defined in their toolchain as an integer.
This PR renames `VERSION` into `RIOT_VERSION`, because that's what it
is.
For many modules the `Makefile` contains a line like
```
MODULE:=$(shell basename $(CURDIR))
```
This conclusively shows that we do not have to set the module name
manually.
This PR removes the need to set the module name manually, if it is the
same as the basename. E.g. for `…/sys/vtimer/Makefile` the variable
make `MODULE` will still be `vtimer`, because it is the basename of the
Makefile.
The scheduling gets activated by `kernel_init()` calling
`cpu_switch_context_exit()`. Before this `sched_run()` won't be called.
When it gets called, at least the main thread and the idle thread are
spawned. The idle thread won't die / get killed. So there always is at
least one thread in `runqueue_bitcache`.
Closes#19.
