Examples with Fingerprint com.google.devtools.build.lib.util.Fingerprint used on opensource projects

Example 36 with Fingerprint

use of com.google.devtools.build.lib.util.Fingerprint in project bazel by bazelbuild.

the class NativeDepsHelper method getSharedNativeDepsPath.

/**
   * Returns the path of the shared native library. The name must be
   * generated based on the rule-specific inputs to the link actions. At this
   * point this includes order-sensitive list of linker inputs and options
   * collected from the transitive closure and linkstamp-related artifacts that
   * are compiled during linking. All those inputs can be affected by modifying
   * target attributes (srcs/deps/stamp/etc). However, target build
   * configuration can be ignored since it will either change output directory
   * (in case of different configuration instances) or will not affect anything
   * (if two targets use same configuration). Final goal is for all native
   * libraries that use identical linker command to use same output name.
   *
   * <p>TODO(bazel-team): (2010) Currently process of identifying parameters that can
   * affect native library name is manual and should be kept in sync with the
   * code in the CppLinkAction.Builder/CppLinkAction/Link classes which are
   * responsible for generating linker command line. Ideally we should reuse
   * generated command line for both purposes - selecting a name of the
   * native library and using it as link action payload. For now, correctness
   * of the method below is only ensured by validations in the
   * CppLinkAction.Builder.build() method.
