If you are interested in making a proposal, feel free to do so and expect to count on support -with design reviews, coding and merging your contributions. Contact herman_venter@msn.com if you want to discuss this -further. - -## Who should use MIRAI - -MIRAI can be used as a linter that finds panics that may be unintentional or are not the best way to terminate a -program. This use case generally requires no annotations and is best realized by integrating MIRAI into a CI pipeline. - -MIRAI can also be used to verify correctness properties. Such properties need to be encoded into annotations of the -source program. - -A related use is to better document an API via explicit precondition annotations and then use MIRAI to check that -the annotations match the code. - -Finally, MIRAI can be used to look for security bugs via taint analysis (information leaks, code injection bugs, etc.) -and constant time analysis (information leaks via side channels). Unintentional (or ill-considered) panics can also -become security problems (denial of service, undefined behavior). - -## How to use MIRAI - -You'll need to install MIRAI as described -[here](https://github.com/facebookexperimental/MIRAI/blob/main/documentation/InstallationGuide.md). - -Then use `cargo mirai` to run MIRAI over your current package. This works much like `cargo check` but uses MIRAI rather -than rustc to analyze the targets of your current package. - -`cargo mirai` does a top-down full-program path sensitive analysis of the -[entry points](https://github.com/facebookexperimental/MIRAI/blob/main/documentation/Overview.md#entry-points) of your -package. To analyze test functions instead, use `cargo mirai --tests`. - -This will likely produce some warnings. Some of these will be real issues (true positives) that you'll fix by changing -the offending code. Other warnings will be due to limitations of MIRAI and you can silence them by adding annotations -declared in this [crate](https://crates.io/crates/mirai-annotations). - -Once MIRAI gives your code a clean bill of health, your code will be better documented and more readable. Perhaps you'll -also have found and fixed a few bugs. - -You can use the environment variable `MIRAI_FLAGS` to get cargo to provide command line options to MIRAI. The value is a -string which can contain any of the following flags: - -- `--diag=default|verify|library|paranoid`: configures level of diagnostics. With `default` MIRAI - will not report errors which are potential 'false positives'. With `verify` it will point out - functions that may contain such errors. With `library` it will require explicit preconditions. - With `paranoid` it will flag any issue that may be an error. -- `--single_func `: the name of a specific function you want to analyze. -- `--body_analysis_timeout `: the maximum number of seconds to spend analyzing a function body. -- `--call_graph_config `: path to configuration file for call graph generator (see [Call Graph Generator documentation](documentation/CallGraph.md)). No call graph will be generated if this is not specified. -- `--print_function_names`: just print the source location and fully qualified function signature of every function. -- `--`: any arguments after this marker are passed on to rustc. - -You can get some insight into the inner workings of MIRAI by setting the verbosity level of log output to one of -`warn`, `info`, `debug`, or `trace`, via the environment variable `MIRAI_LOG`. - -## Developing MIRAI -See the [developer guide](https://github.com/facebookexperimental/MIRAI/blob/main/documentation//DeveloperGuide.md) -for instructions on how to build, run and debug MIRAI. -## Full documentation -* [Overview of project](https://github.com/facebookexperimental/MIRAI/blob/main/documentation/Overview.md). -* [Architecture](https://github.com/facebookexperimental/MIRAI/blob/main/documentation/Architecture.md). -* [Design discussions](https://github.com/facebookexperimental/MIRAI/blob/main/documentation/DesignDiscussions.md). -* [Further reading](https://github.com/facebookexperimental/MIRAI/blob/main/documentation/FurtherReading.md). +It started out as a Facebook project, but became orphaned when the sponsoring organization was disbanded. -## Join the MIRAI community - -See the [CONTRIBUTING](https://github.com/facebookexperimental/MIRAI/blob/main/CONTRIBUTING.md) file for how to help out. +Ongoing work to keep the project alive now happens at https://github.com/endorlabs/MIRAI. -## License -MIRAI is MIT licensed, as found in the [LICENSE](https://github.com/facebookexperimental/MIRAI/blob/main/LICENSE) file.
