Add function "has_binary_license" to check if a file has a non-permissive license contains one. PBL is not recognized by scancode,
causing it to be flagged as a non-permissive license. CI doesn't allow
any non-permissive licenses, although, files flageed as SPDX are
allowed. Workaround causes all files with a valid PBL to be flagged as
missing an SPDX.
Add condition in "has_spdx_text_in_scancode_output" to ignore any spdx
identifier with "unknown" in the name. Scancode erroneously matches PBL to matched_rule.identifer "spdx-license-identifier: unknown-spdx". This prevents the workaround from working.
ScanCode can possibly return many licenses found for a single file scanned.
This commit ensures that the file is not reported as lacking a permissive license
if at least one license found in it is permissive.
Previously the script was reporting an issue if it found at least one license
in a file that was not permissive.
Additionally catch more errors and provide specific details about failures.
Provide unitest.
Add unit test and dependent stubs for testing of scancode-evaluate.py.
license_check takes a JSON as argument and checks for source missing
copyright or license notices.
Each JSON represents a separate test case, and stubs are added for test case
3 and 4 where license_check looks for an spdx notice in the source file.
