Make sure we have enough POSIX key value pairs available. This fixes a test
failure on some targets.
Make objects and functions static. Initialize variable to get rid of warnings.
This adds the configure option CONFIGURE_POSIX_TIMERS_FACE_BEHAVIOR
which allows the application to choose whether to have the POSIX
timer_create() function follow the behavior defined by POSIX or
the FACE Technical Standard.
Updates #4691.
The rtems_task_delete() directive is basically just a combined pthread_cancel()
and pthread_join(). In addition, it removes the PTHREAD_DETACHED state. The
exit value returned by pthread_join() of threads cancelled by
rtems_task_delete() should reflect this by getting a PTHREAD_CANCELED value
instead of NULL which could be a normal exit value.
Close#4680.
Threads may join the thread termination of another thread using the
pthread_join() or rtems_task_delete() directives. The thread cancel operation
used a special case priority boosting mechanism implemented by
_Thread_Raise_real_priority(). The problem was that this approach
* is not transitive,
* does not account for priority adjustments of the calling task
while waiting for the join,
* does not support clustered scheduling, and
* does not detect deadlocks.
All these problems are fixed by using a priority inheritance thread queue for
the join operation.
Close#4679.
Currently the following sequence causes a endless loop when extending an
IMFS file:
- Create a file with zero length and close it.
- Make sure nearly no allocatable memory is left.
- Open the file and write enough data into it that more than the
remaining memory will be used.
In that case when extending the IMFS file, the file currently need zero
blocks. If allocating enough new blocks fails, the already allocated new
blocks will be freed again.
The comparison of block>=old_blocks that has been used prior to this
patch compared two unsigned numbers. If old_blocks was zero, the
comparison of these two numbers always evaluated to true.
This patch frees the last block in a separate step to avoid this
problem.
Fixes#4639
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.
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
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.
Do not adjust the stack area begin address since this may confuse the
stack allocator and result in failed stack frees.
Account for the alignment overhead in the stack space size estimate.
Check that the stack size is in the expected interval.
This fixes the following compiler warning:
testsuites/psxtests/psxndbm01/init.c:221:3: warning: 'strncpy' output truncated
before terminating nul copying 5 bytes from a string of the same length
221 | strncpy( test_strings, "Hello", 5 );
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In addition, the comments from Sebastian Huber on an old version of
such a patch have been taken into account:
1) The use of `sizeof()` in `key.dsize = sizeof( test_strings );` is wrong.
2) There is no need to allocate the string. One can simply use a string
constant.
