Remove forced overwrite which leads to file data corruption. The logic
to determine a forced overwrite was fundamentally broken. For simplity,
disable this feature.
Update #2622.
It is all right in case the result uses the full destination buffer.
Without this fix the handling of a maximum 8.3 short file name is
broken.
Update #2928.
Perform a context-dependent deferred location release to avoid a
deadlock on the file system instance locks, for example during a
chdir().
Update #2936.
Currently only blocking read/write operations are implemented. A
blocking write must transfer at least one character. It should not wait
for the device for the second character and so on.
Close#2917.
Call the receive callback in case a read will succeed without to block.
This enables the use of the receive callback for a poll() and select()
support. Increase raw input buffer size to allow buffering of one line.
Close#2916.
In case carriage return characters should be ignored in the input
(IGNCR), then drop them early before they reach the raw input buffer.
This makes it easier to calculate the content size of the raw input
buffer.
Only register ask for help requests in the scheduler unblock and yield
operations. The actual ask for help operation is carried out during
_Thread_Do_dispatch() on a processor related to the thread. This yields
a better separation of scheduler instances. A thread of one scheduler
instance should not be forced to carry out too much work for threads on
other scheduler instances.
Update #2556.
Instead of using the target time and console driver, both tests now use
assertions and rtems_rate_monotonic_get_status() to verify the count of
postponed jobs. The setting of spedfsched04 is slightly changed.
Close#2795.
Prepare a precondition to prevent the potential integer overflow.
Remove one redundant parameter in _Rate_monotonic_Renew_deadline().
sptests/sprmsched02: Create
A test case for checking the overflow condition of postponed_jobs
in rtems_rate_monotonic_period_status.
Update #2885.
Use forward and reverse order for initial and dynamic extensions. This
is the behaviour documented in the C Users Guide. Change thread
terminate order to backward to be in line with the thread delete order.
Change fatal error order to forward to ensure that initial extensions
are called first due the peculiar execution context of fatal error
extensions, see _Terminate() documentation.
Update #2692.
Add a variable named "count" in rtems_rate_monotonic_period_status
structure. Revise rtems_rate_monotonic_get_status() for the postponed
job count.
sptests/sp69: Add in the verification of the postponed job count for
rtems_rate_monotonic_get_status().
Update #2795.
Add POSIX shared memory manager (Shm). Includes a hook-based
approach for the backing memory storage that defaults to the
Workspace, and a test is provided using the heap. A test is
also provided for the basic use of mmap'ing a shared memory
object. This test currently fails at the mmap stage due to
no support for mmap.
