Master branch contains lot of missing SPDX identifiers, we will clean them up but this will take some time. In the meantime, we should not increase the license missing files. Each PR will report if there is no license issue or positive number reported as Github status. Travis won't fail if there are issues. This will highlight the issues that anyone can fix.
As soon as master is clean, we can fix set_status and revert part of this commit.
The goal: check license offenders in pull request
This is similar to what astyle does in Travis. We get list of files being changed. Because scancode does not support list of files being scanned but rather a file or directory, we copy files to SCANCODE folder. Execute scancode license check in this folder and check for offenders.
The rules there are: code files must have a license and SDPX identifier. If they don't, we print these and ask for review.
It functions nicely there is just one workaround needed. SPDX is not always 100 percent correctly found, therefore we recheck file if no SPDX manually in the script. This proves to remove false positives.
Assert it properly and thus give out the target name where the
issue is, rather than just error out with KeyError and leave the
poor sod wondering where exactly the issue is.
Before:
```

E AssertionError: Target NUCLEO_L073RZ does not have sectors
E assert 'sectors' in {'algorithms': [{'default': True, 'file_name': 'CMSIS/Flash/STM32L0xx_192.FLM', 'ram_size': None, 'ram_start': None, ....on_secure_callable': False, 'peripheral': False, ...}, 'default': True, 'size': 196608, 'start': 134217728, ...}}, ...}
```
This helps you finding the offending target a bit faster.
Kudos to Jammu Kekkonen (jammu.kekkonen@arm.com) to figuring out how to actually
run this test & the assertion.
Ref: Mbed OS issue #12219
- By default, Mbed OS build tools use standard C library for all supported toolchains.
It is possible to use smaller C libraries by overriding the "target.default_lib" option
with "small". This option is only currently supported for the GCC_ARM toolchain.
This override config option is now extended in the build tool for ARM toolchain.
- Add configuration option to specify libraries supported for each toolchain per targets.
- Move __aeabi_assert function from rtos to retarget code so it’s available for bare metal.
- Use 2 memory region model for ARM toolchain scatter file for the following targets:
NUCLEO_F207ZG, STM32F411xE, STM32F429xI, NUCLEO_L073RZ, STM32F303xE
- Add a warning message in the build tools to deprecate uARM toolchain.
- NewLib-Nano C library is not supporting floating-point and printf with %hhd,%hhu,%hhX,%lld,%llu,%llX
format specifier so skipping those green tea test cases.
Planning to update to supporting GCC 9 as found in GNU Tools for Arm
Embedded Processors 9-2019q4-major.
Newer GCC in particular supports ARMv8-M security extensions, and
link-time optimisation - two areas of interest.
Should be no code changes required, but need to change the warning in
the toolchain script.
Currently mbed-os-example-blinky and mbed-os-example-wifi are built for each and every target in Mbed OS. This will change that only DISCO_L475VG_IOT01A is built for mbed-os-example-wifi. DISCO_L475VG_IOT01A was chosen as its one of the wi-fi supported boards and having integrated wi-fi.
The retarget code allocates an array of FileHandle* for console and file
handling (filehandles). A tiny target only needs a console (putc/getc).
There is no need for file handling.
The POSIX layer and the array of FileHandle* is not required for small
targets that only need a console ; this code is optionally compiled
out if the configuration parameter platform.stdio-minimal-console-only is
set to `"true"`.
All scripts pertaining to example projects tests should be in the same
directory. The test framework uses Python2 therefore this script also needs
to be Python2 compatible.
