| /** |
| * The BuildView presents a semantically-consistent and transitively-closed dependency graph for |
| * some set of packages. |
| * |
| * <h2>Package design</h2> |
| * |
| * <p>This package contains the Blaze dependency analysis framework (aka "analysis phase"). The goal |
| * of this code is to perform semantic analysis of all of the build targets required for a given |
| * build, to report errors/warnings for any problems in the input, and to construct an "action |
| * graph" (see {@code lib.actions} package) correctly representing the work to be done during the |
| * execution phase of the build. |
| * |
| * <p><b>Configurations</b> the inputs to a build come from two sources: the intrinsic inputs, |
| * specified in the BUILD file, are called <em>targets</em>. The environmental inputs, coming from |
| * the build tool, the command-line, or configuration files, are called the <em>configuration</em>. |
| * Only when a target and a configuration are combined is there sufficient information to perform a |
| * build. |
| * |
| * <p>Targets are implemented by the {@link Target} hierarchy in the {@code lib.packages} code. |
| * Configurations are implemented by {@link BuildConfiguration}. The pair of these together is |
| * represented by an instance of class {@link ConfiguredTarget}; this is the root of a hierarchy |
| * with different implementations for each kind of target: source file, derived file, rules, etc. |
| * |
| * <p>The framework code in this package (as opposed to its subpackages) is responsible for |
| * constructing the {@code ConfiguredTarget} graph for a given target and configuration, taking care |
| * of such issues as: |
| * |
| * <ul> |
| * <li>caching common subgraphs. |
| * <li>detecting and reporting cycles. |
| * <li>correct propagation of errors through the graph. |
| * <li>reporting universal errors, such as dependencies from production code to tests, or to |
| * experimental branches. |
| * <li>capturing and replaying errors. |
| * <li>maintaining the graph from one build to the next to avoid unnecessary recomputation. |
| * <li>checking software licenses. |
| * </ul> |
| * |
| * <p>See also {@link ConfiguredTarget} which documents some important invariants. |
