Edit assert statements in worker thread to check initialization against the
__cleanup member of struct _reent instead of __sdidinit. This will allow the
removal of sdidinit in a follow up Newlib patch.
Avoid a dependency on errno which might be a thread-local object. The tests
sp01, spstkalloc02, and sptls03 assume that no thread-local storage object is
present.
Update #4560.
When the stack checker is not enabled, the stack checker reporting
function can still be called. This prevents that call from performing a
null memory access in trying to find the high water mark if the stack
checker was never initialized.
This also introduces a test to ensure this call does not cause a crash.
Closes#4588
GCC versions prior to 6.1 used a RTEMS thread model based on
rtems_gxx_*() functions. GCC version 6.1 or later uses the
self-contained synchronization objects of Newlib <sys/lock.h> for the
RTEMS thread model.
Remove the obsolete implementation.
Close#3143.
RTEMS untar implementation had problems with overwriting or integrating
archives into existing directory structures. This patch adapts the
behavior to mimic that of a GNU tar or BSD tar and extends the tar01
test to check for the behavior. That is:
* If a directory structure exists, the files from the archive will be
integrated. Existing files are overwritten.
* If a file exists and the archive contains a directory with the same
name, the file is removed and a directory is created. In the above
example: if l1/l2 is a file it will be overwritten with a new
directory.
* If a directory exists and the archive contains a file with the same
name, the directory will be replaced if it is empty. If it contains
files, the result is an error.
* An archive also can contain only a file without the parent
directories. If in that case one of the parent directories exists as a
file extracting the archive results in an error. In the example: if
l1/l2 is a file and the archive doesn't contain the directories but
only the file l1/l2/x.txt that would be an error.
* In case of an error, it is possible that the archive has been
partially extracted.
Closes#4568
The BSPs provide memory for the separate C Program Heap initialization
via _Memory_Get(). Most BSPs provide exactly one memory area. Only two
BSPs provide more than one memory area (arm/altera-cyclone-v and
bsps/powerpc/mpc55xxevb). Only if more than one memory area is
provided, there is a need to use _Heap_Extend(). Provide two
implementations to initialize the separate C Program Heap and let the
BSP select one of the implementations based on the number of provided
memory areas. This gets rid of a dependency on _Heap_Extend(). It
also avoids dead code sections for most BSPs.
Change licence to BSD-2-Clause according to file history.
Update #3053.
Remove the THREAD_WAIT_STATE_READY_AGAIN and simply use the initial value to
indicate that a thread does not wait on something. Rename
THREAD_WAIT_FLAGS_INITIAL to THREAD_WAIT_STATE_READY. This change is necessary
so that _Thread_Continue() can be called for threads which never waited on
something (for example dormant threads).
Update #4546.
This patch set replaces the CPU budget algorithm enumeration with a set of CPU
budget operations which implement a particular CPU budget algorithm. This
helps to hide the CPU budget algorithm implementation details from the general
thread handling. The CPU budget callouts are turned into CPU budget
operations. This slightly reduces the size of the thread control block.
All schedulers used the default scheduler tick implementation. The tick
scheduler operation is removed and the CPU budget operations are directly used
in _Watchdog_Tick() if the executing thread uses a CPU budget algorithm. This
is performance improvement for all threads which do not use a CPU budget
algorithm (default behaviour).
This fix came from Code Inspector, flagged by one of the analysis that
was done.
This test code is compiled only but better to address the issues so
future static analysis reports will not include it.
Add a stack allocator hook specifically for allocation of IDLE thread stacks.
This allows the user to decide if IDLE thread stacks are statically allocated
or handled by the same custom allocator mechanism as other thread stacks.
Closes#4524.
Do not use a direct thread dispatch in
_Thread_queue_Surrender_priority_ceiling() since it may be used in condition
variables using POSIX mutexes.
Close#4526.
The utimbuf structs in fsimfsconfig01 and fsimfsconfig02 were
being passed to utime uninitialized. This did not cause problems until
utime was changed to use utimensat behind the scenes. Now that
utimensat is called, the values of the utimbuf struct are checked, and
EINVAL is set for invalid values. The utimebuf structs in these tests
could contain invalid values since they are uninitialized.
By zero-initializing the utimbuf structs, we ensure that they pass the
checks in utimensat and that errno is set to the expected ENOTSUP.
The order in which step checks for 1 and 2 are not rigidly defined and
may actually occur in either order depending on how the threads execute.
This waits for the job to complete to enforce the existing ordering.
psxdevctl is supposed to return the value in errno. Before, it was
returning -1 and setting errno. Changed the tests to reflect these
changes. Added code from RRADE's posix_devctl.c.
Closes#4506
This simplifies the implementation a bit. Declare _TOD_Days_to_date[] in
<rtems/score/todimpl.h>. Make _TOD_Days_per_month[] and
_TOD_Days_since_last_leap_year[] static.
Update #4338.
Move the transition map members of the test context to a dedicated
structure. Move the transition variant pre-condition prepare, action,
and post-condition checks to a separate function to reduce the
indentation level and allow skipping of transition variants.
Use the new Priority_Group_order enum instead of a boolean to indicated if a
priority should be inserted as the first or last node into its priority group.
This makes the code more expressive. It is also a bit more efficient since a
branch in _Scheduler_Node_set_priority() is avoided and a simple bitwise or
operation can be used.
the timer_create() method can use CLOCK_MONOTONIC
but there was no test for this.
Also it implements the functionality to
create a CLOCK_MONOTONIC timer and gettime() .
Closes#3888
Cloning under Cygwin turned off executable permission on these
files. This shows them as modified even though they have not
explicitly been touched. Executable permission should not have
been on for these files so this is just a minor clean up.
The per-CPU states which control the SMP system initialization were added quite
early during the SMP support development. Replace this initial implementation
with a simplified one. There is no longer a global SMP lock required which
serialized the state changes of all processors. The new implementation better
integrates with the per-CPU jobs.
Remove _CPU_SMP_Processor_event_broadcast() and
_CPU_SMP_Processor_event_receive(). These functions are hard to use since they
are subject to the lost wake up problem.
Users have access to the fatal error source and code though the fatal error
extension. The user-specific fatal error handling should be done in statically
initialized fatal error handlers. The _Internal_errors_What_happened was
updated after the fatal error extension. In addition, there was no API to get
the information stored in _Internal_errors_What_happened. In SMP
configurations, this object could contain a mix of different fatal errors.
Remove this object to save some bytes of storage.
