This commit extends the backend-side infrastructure of injection points so as it becomes possible to register some input data when attaching a point. This private data can be registered with the function name and the library name of the callback when attaching a point, then it is given as input argument to the callback. This gives the possibility for modules to pass down custom data at runtime when attaching a point without managing that internally, in a manner consistent with the callback entry retrieved from the hash shmem table storing the injection point data. InjectionPointAttach() gains two arguments, to be able to define the private data contents and its size. A follow-up commit will rely on this infrastructure to close a race condition with the injection point detach in the module injection_points. While on it, this changes InjectionPointDetach() to return a boolean, returning false if a point cannot be detached. This has been mentioned by Noah as useful when it comes to implement more complex tests with concurrent point detach, solid with the automatic detach done for local points in the test module. Documentation is adjusted in consequence. Per discussion with Noah Misch. Reviewed-by: Noah Misch Discussion: https://postgr.es/m/20240509031553.47@rfd.leadboat.com |
