guava-generator

This is a collection of python scripts which serve the purpose of mechanically repackaging and modularizing Guava

• reset.py will set each of the submodules to their most recent main
• upgrade.py will do a find+replace of a version string in the required files for each submodule
• foreach.py will run a command for each submodule
• compile.py will attempt to run mvn compile for each submodule
• generate.py will update the code of all of the submodules to the given commit hash of guava
• commit.py will push changes to remote repos

Usage

Consult the repos for the subprojects for the latest releases and dependency information.

Changes made from Guava

• Everything is shaded under dev.mccue.guava
  • com.google.common.util.concurrent is turned into dev.mccue.guava.concurrent, dropping the util
• All usages of sun.misc.Unsafe are removed
  • The unsafe implementation is removed, leaving a safe fallback in LittleEndianByteArray, AbstractFuture, and UnsignedBytes
  • The unsafe implementation in is replaced with a new one based on VarHandles in Striped64
• All usages of sun.misc.JavaLangAccess are removed
  • Replaced with Throwable.getStackTrace in Throwables
• All usages of finalize() are removed
  • FileBackedOutputStream has a constructor which takes a boolean to indicate that resources should be freed on finalization. This was made private and the logic was removed.
• All usages of the Security Manager are removed
  • Types catches an AccessControlException and that could safely be replaced with catching an Exception
  • Explicit uses of the security manager in LittleEndianByteArray, AbstractFuture, UnsignedBytes, and Striped64 were removed along with the code to load sun.misc.Unsafe.
• All usages of java.util.logging.Logger were replaced with java.lang.System.Logger
  • With this change, the only JDK module depended on is java.base.
• All usages of javax.annotation.* classes from com.google.code.findbugs/jsr305 are replaced with equivalent classes from dev.mccue/jsr305
• FinalizableReferenceQueue and associated classes were removed
  • They were rarely used, probably do a job better done by a Cleaner, and I wasn't able to validate that they would behave correctly in a module
• Annotation modules are used via requires static and are not carried over to dependents.
• All annotation usages from com.google.common.annotations and com.google.j2objc.annotations have been removed
• Split into multiple submodules, each with their own module-info.java
• Drops explicit support for GWT, j2objc, j2cl, etc.
• Drops explicit support for android (equivalent to the -jre build)
• Does not include
  • com.google.common.eventbus (Guava docs explicitly recommends against its use)
  • com.google.common.cache (Caffiene covers that use.)
  • com.google.common.annotations (Only @Beta and @VisibleForTesting would be relevant without GWT+etc. testing, and you can make your own pretty easily.)
• Compiled for Java 9+, not Java 8
