Since there are already excessive NULL pointer checks in the Classic
API, do this also in rtems_task_construct().

This patch fixes issue #4338 by changing _TOD_Validate()
to only accept years till 2105. This requires another patch
to change the documentation of rtems_clock_set() and other
affected API functions (indicating the end date is 2105 not 2514).
I tried to support till year 2514 but it turned out that
this needs changing the Timer Manager too. That in turn
would mean to change _TOD_Seconds_since_epoch( void )
from 32 to 64 bit. Sebastian pointed out that a naive extension
leads to trouble with 32 bit processors. He deemed a safe
re-implementation too costly performance wise considering
that year 2106 is far away and current binaries using RTEMS
Classic API are unlikely to be in use by 2106.
The constant TOD_SECONDS_AT_2100_03_01_00_00 in
cpukit/rtems/src/clocktodtoseconds.c happens to be wrong by
1 hour. When setting the date 2100-Feb-28 23:59:59 and then
reading the date again you will find yourself in 2100-Feb-27.

Replace Objects_Name_or_id_lookup_errors with new Status_Control codes.
Get rid of the _Status_Object_name_errors_to_status lookup table.
|
|
The value of STATUS_CLASSIC_INTERNAL_ERROR must be equal to
RTEMS_INTERNAL_ERROR. Add static assertions to ensure that the status
codes match.
|
|
Check only for invalid modes if a valid handler is presented to
rtems_signal_catch(). When NULL is used for the handler, ASR processing
is disabled and the mode is not used.
Update #4244.
|
|
Do the ASR and preemption mode change only if requested by the mode
mask. The bug was introduced by
508f868237225a75e566d9fd304206363cfe441d.
|
|
Do not mix checks for different error indicators (RTEMS_NOT_DEFINED and
RTEMS_INVALID_NUMBER). This simplifies the specification of
rtems_semaphore_create().
|
|
MrsP semaphores are a generalization of the priority ceiling semaphores
for SMP configurations. Priority ceiling semaphores are required to use
the priority task wait queue discipline. Require this discipline also
for MrsP semaphores.
Close #4347.
|
|
In uniprocessor configurations, we can simplify rtems_signal_catch().
Add a validation test for the SMP special case.
|
|
Use the invariant that an ASR is only processed if ASR processing is
enabled.
|
|
Close the thread object if a thread create extension fails. Also call
the delete extension to avoid resource leaks in early extensions if a
late extension fails.
Close #4270.
|
|
Use the number of threads which must arrive at the barrier to trip the
automatic release also to indicate if the barrier is a manual release
barrier.
|
|
Use the type safe _Objects_Open_u32() instead. Return the object
identifier to enforce a common usage pattern.
|
|
Do the preemption and ASR processing changes in one rush and acquire the
thread state lock only once.
|
|
Do the mode changes necessary for the ASR processing directly under
protection of the thread state lock to avoid the recursive calls to
thread dispatching done in rtems_task_mode().
Close #4244.
|
|
Update #4244.
|
|
Ensure that no invalid modes are set during ASR processing.
Update #4244.
|
|
This call just obfuscated the call to _ISR_Set_level().
Update #4244.
|
|
Remove superfluous ASR_Information::signals_posted. Move code out of
trivial inline functions.
Update #4244.
|
|
Move _Signal_Action_handler() and signal MP initialization to
rtems_signal_send(). The goal is to make _Signal_Action_handler() a
static function in a follow up patch.
Update #4244.
|
|
Update #4244.
|
|
Require that the corresponding lock is acquired before the action
handler returns. This helps to avoid recursion in the signal
processing.
Update #4244.

- Move the heap sbrk code into a separate routnine.
- Update heap and workspace greedy allocators to use the common
sbrk greedy support.
Closes #3982

|
Use the rtems_clock_get_ticks_per_second() macro to implement the
rtems_clock_get_ticks_per_second() function.
|
|
Add a "Constraints" paragraph to the documentation.
Provide prototypes for programming language bindings. Use the macro
implementation to implement the corresponding functions.
Update #3993.
|
|
This fix relates to a Coverity issue (UNUSED_VALUE).
|

We do not need all the checks if we have a valid indentifier to a thread
class object.
Using the new _Thread_Get_objects_information() instead of the inline
function _Thread_Get_objects_information_by_id() avoids dead code since
the identifier in a thread control is always valid and the return NULL
path in _Thread_Get_objects_information_by_id() would be dead code. The
_Thread_Get_objects_information_by_id() should be an inline function
since it is used by _Thread_Get() and thus performance critical. Static
analyzers which cannot derive that the identifier in a thread control is
always valid, may find a potential NULL pointer access (or otherwise
find dead code).
The identifier in an object control is always valid, see
_Objects_Initialize_information() and _Objects_Extend_information().
Move _RTEMS_tasks_Free() to the only source file which calls this
function.

|
This fixes implicit conversions between different enum types.
|
|
Return RTEMS_NO_MEMORY if there is not memory available to duplicate the
name.
|
|
Use common phrases for the file brief descriptions.
Update #3706.
|
|
Rename Classic API top-level group from Classic to RTEMSImplClassic.
Use RTEMSImplClassic as a prefix for the subgroups. Change the group
names to be in line with the API group names. Use common phrases for
the group brief descriptions.
Update #3706.

|
|
|
In order to better support applications which use the new
rtems_task_construct() directive add the
CONFIGURE_INIT_TASK_CONSTURCT_STORAGE_SIZE configuration option. If
this option is specified, then the Classic API initialization task is
constructed with rtems_task_construct().
Update #4181.
|
|
Replace a runtime check with a compile time assertion. This makes the
INTERNAL_ERROR_RTEMS_INIT_TASK_ENTRY_IS_NULL obsolete.
Update #4181.
