Likewise, if all of the data that describes a particular transaction in progress is held together as a coherent chunk, and all access to it is through known, narrow interfaces, then it is easier to monitor that state from a different machine—which can then take over smoothly in the event of failure. Fully parsing a high-level programming language is non-trivial (especially for something as complicated as C++); however, if the coding standards impose some additional structure, it’s often possible to get useful information with more trivial tools (such as scripts written in awk or Perl). This means that the build should be easy to run from beginning to end, preferably with a single command, and it should ideally have reliable dependency checking so that only code that has changed gets rebuilt—in a large codebase, anything else is tempting the developers to cut corners.
