This class was copy-pasted in all `DataFlowN.qll` files without using the identical-files system to keep the copies in sync. The class is now moved to the `DataFlowImplN.qll` files. This also has the effect of preventing recursion through first data flow library copy for C/C++. Such recursion has been deprecated for over a year, and some forms of recursions are already ruled out by the library implementation.
Semmle QL
This open source repository contains the standard QL libraries and queries that power LGTM, and the other products that Semmle makes available to its customers worldwide.
How do I learn QL and run queries?
There is extensive documentation on getting started with writing QL. You can use the interactive query console on LGTM.com or the QL for Eclipse plugin to try out your queries on any open-source project that's currently being analyzed.
Contributing
We welcome contributions to our standard library and standard checks. Do you have an idea for a new check, or how to improve an existing query? Then please go ahead and open a pull request! Before you do, though, please take the time to read our contributing guidelines. You can also consult our style guides to learn how to format your QL for consistency and clarity, how to write query metadata, and how to write query help documentation for your query.
