The CommandExecutor helper class can execute shell commands in blocking and non-blocking mode
This class is able to execute processes by using the Linux popen call. It also has the capability of writing
the read output of a process into a provided ring buffer.
The executor works by first loading the command which should be executed and specifying whether
it should be executed blocking or non-blocking. After that, execution can be started with the execute call.
Using non-blocking mode allows to execute commands which might take a longer time in the background,
and allowing the user thread to check completion status with the check function
Moved to HAL like requested in code review and unit tested with failing commands as well.
Also, Linux HAL components are compiled by default now unless explicitely disabled.
This PR adds the packet stack for the CCSDS File Delivery Protocol.
It also refactors the existing TMTC infastructure to allow sending
of CFDP packets to the CCSDS handlers.
This includes the whole PDU (Protocol Data Unit) stack:
- File Data PDUs
and all file directive PDUs
- ACK PDU
- NAK PDU
- Metadata PDU
- Finished PDU
- Prompt PDU
- Keep Alive PDU
- EOF PDU
The PR includes a full set of unittests for the packet stack
with a coverage of 90+ %.
The refactoring of the existing TMTC infastructure includes non-ideal
solutions like diamond inheritance.
Avoiding this solution would require refactoring the packet stack.
This would be a good idea anyway because the existing stack is tightly
coupled to the FSFW, making reuse more difficult if only the stack is
planned to be used without the store functionalities etc.
The PDU implementation provided here is only weakly coupled to the FSFW,
only using components like returnvalues or the Serialization modules.
There are dedicated serializers and deserializers, which also helps in
creating small focused modules which are easy to test.
Some of the modules here were provied by Matthias Tompert.
1. Added .clang-format file which contains information for the
clang-format tool on how to format source files
2. Added shell helper script to apply all changes on HAL soures,
test sources and primary sources
The shell script was not applied yet. This should be done shortly
before introducing the release. Also, it might be good idea to provide
instructions on how to set up the formatter for Eclipse
This PR introduces the generation of documentation based on
this excellent blog post: https://devblogs.microsoft.com/cppblog/clear-functional-c-documentation-with-sphinx-breathe-doxygen-cmake/
It combines the tools Sphinx, Doxygen and Breathe to generate good
looking HTML documentation conveniently which can be hosted easily.
The helper scripts were unified and there is now one helper.py script
which can be used to create, build and open both tests and documentation.
"./helper.py -h" can be used to get the different options.
This PR also contains some smaller fixes which were necessary for the docs
to build
- Added unittests for `PeriodicOperationDivider` and the `bitutil` helpers
- Some API changes: Removed redundant bit part, because these functions are already in a namespace
- Some bugfixes for `PeriodicOperationDivider`
