In the config store create test in test case #5 the amount of available
memory is determined by fully allocating the heap. This is done
multiple times to determine if there is a memory leak. This causes
problems when even slight fragmentation occurs in the heap, since
the size that can be allocated is decreased slightly, which the test
flags as a memory leak.
This patch makes memory leak detection more robust by using metrics
provided by mbed_stats_heap_get. These metrics are an exact
measurement of memory allocated is not changed by fragmentation.
This allows the memory leak test to report correct values regardless of
fragmentation.
Changes:
Refactor examples.py to add a new command line option to provide an update
tag.
Refactor examples.py to add new functionality to update the version of
mbed-os in the examples to a supplied tag.
Refactor examples.py to make cloning the example repos, updating their
mbed-os version and compiling, into library functions and move to a new
library module.
Refactor the format of the examples.json file to make it compatible with
both examples.py and update.py.
Refactor update.py so that examples are test compiled prior to updating.
Refactor update.py so that only examples tagged as auto-updatable and that
fully compile are automatically updated.
Previous code base had been wasting almost 4K of precious RAM.
* Main stack allocation reduced from 4K to 1K
* Un-necessary breakdown of RAM regions is removed. This gives us back 2K of RAM.
When closing a file handle remove the handle from the handle list
regardless of what the reference count of the key it is pointing to is.
This prevents config store from keeping a handle to file handles that
have gone out of scope.
The function cfstore_delete_ex is written under the assumption that
CFSTORE_REALLOC will never fail if the size is decreasing. Regardless
of the status of CFSTORE_REALLOC the entry is removed from the config
store and zeroed. This works correctly if CFSTORE_REALLOC correctly
updates area_0_tail, but can lead to crashes in the case area_0_tail is
left unchanged. The crash is because when iterating over the config
store data, cfstore_get_next_hkvt is unable to determine the end of
valid data.
This patch fixes this problem by handling the realloc failure case by
updating area_0_tail even if CFSTORE_REALLOC returns NULL. This
patch also adds an assert to check for out of bound entries in when
calling cfstore_get_next_hkvt. This allows an assert to be triggered
if this bug is re-introduced, rather than a crash.
When the config store is powered down area_0_head is freed, but
area_0_len is not set to 0. This causes when cfstore_realloc_ex is
called, since on the first allocation it appears that the config store
size is decreasing, and therefore the data is not initialized.
Since the data is uninitiated various fields such as the reference
can have invalid values. On GCC_ARM built with heap stats enabled
this manifests as a crash due to an invalid reference count.
This patch fixes this problem by setting area_0_len to 0 when the data
is freed.
Currently only one network interface can be compiled in at a given time,
to avoid failing automated test on this target WiFi will be disabled by default.
* Binary build script is modified to follow currebt mbedOS baseline structure
* License files are moved to the correct location.
* Contribution.md is also moved to the correct location.
STM32F303ZE was introduced in parallel to the changes which consist in
having family wide definitions like device.h file and a common objects
definition.
This target is updated accordingly now to benefit of SPI definitions.
