| /** |
| * <p>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> |
| * |
| * <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. |
