[OK] TRLC Compreq MwLog.InactiveLogStreamBehavior

mw::log library shall not perform any useful activity if log level of LogStream object is insufficient for given context. LogStream object shall not generate serialized messages if the severity of the message does not allow it to be sent.

[OK] TRLC Compreq MwLog.SharedMemoryFilePermissions

Logging shared-memory files shall have read-only posix file permission for group and others. The shared-memory file created by mw::log shall be read-only for group and others.

Derived from:

Source: score/mw/log/requirements/component_requirements/component_requirements.trlc:67:18

[OK] TRLC Compreq MwLog.LocalAllocationStrategy

mw::log shall use local allocators to avoid using global heap. Global heap allocation (if any) shall be limited to the initialization phase of application lifecycle.

Source: score/mw/log/requirements/component_requirements/component_requirements.trlc:103:18

[OK] TRLC Compreq MwLog.TimeBoundedLocking

mw::log shall be free of time-unbound locks and shall implement strategies to limit wait time. Time limit shall be defined based on requirements from functions on individual ECU. Mutual exclusion mechanisms shall include priority inversion protection.

Traces to:

Derived from:

Source: score/mw/log/requirements/component_requirements/component_requirements.trlc:111:18

[OK] TRLC Compreq MwLog.CrossLockingPrevention

Cross-application and cross-thread dependencies shall be avoided. A thread logging in a loop shall not block other thread’s execution.

Source: score/mw/log/requirements/component_requirements/component_requirements.trlc:121:18

[OK] TRLC Compreq MwLog.IndexAndSizeChecking

Indices in data structures and sizes of data accessed or copied shall be checked for plausibility to avoid high runtime utilization through long iterations or data corruption.
