Hello, The Coccinelle software supports multi-processing (parameter “--jobs”) for a while. It would be occasionally useful to share data between started (background) processes for specific analysis tasks. Such parallel data collection would require a software design which is safe for data synchronisation.
The information “Database connections generally do not travel across process boundaries.” is provided by a known software documentation. https://docs.sqlalchemy.org/en/13/core/connections.html#engine-disposal It was determined once more then that transaction management does only work within a single process by this programming interface so far. https://groups.google.com/d/msg/sqlalchemy/5-6O-Pwzh4A/5xSnxE_pDAAJ I got information like the following (on 2018-05-12). @initialize:ocaml@ @@ let _ = if not (!Flag.parmap_cores = None) then failwith "bad" It seems that I did not become familiar enough with the programming language “OCaml” to integrate another check (in a convenient way) for the special case that the parameter “-j 1” could be passed. (Related system constraints can be also interesting.) Would you like to help a bit more to achieve the restriction for serial execution of selected SmPL scripts?
