/**
|
|
* A tool for processing the .sym.txt files.
|
|
*
|
|
* To add historical data for JDK N, N >= 11, do the following:
|
|
* * cd <open-jdk-checkout>/src/jdk.compiler/share/data/symbols
|
|
* * <jdk-N>/bin/java --add-exports jdk.jdeps/com.sun.tools.classfile=ALL-UNNAMED \
|
|
* --add-exports jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED \
|
|
* --add-exports jdk.compiler/com.sun.tools.javac.jvm=ALL-UNNAMED \
|
|
* --add-exports jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED \
|
|
* --add-modules jdk.jdeps \
|
|
* ../../../make/langtools/src/classes/build/tools/symbolgenerator/CreateSymbols.java \
|
|
* build-description-incremental symbols include.list
|
|
* * sanity-check the new and updates files in src/jdk.compiler/share/data/symbols and commit them
|
|
*
|
|
* The tools allows to:
|
|
* * convert the .sym.txt into class/sig files for ct.sym
|
|
* * in cooperation with the adjacent history Probe, construct .sym.txt files for previous platforms
|
|
* * enhance existing .sym.txt files with a new set .sym.txt for the current platform
|
|
*
|
|
* To convert the .sym.txt files to class/sig files from ct.sym, run:
|
|
* java build.tool.symbolgenerator.CreateSymbols build-ctsym <platform-description-file> <target-directory>
|
|
*
|
|
* The <platform-description-file> is a file of this format:
|
|
* generate platforms <platform-ids-to-generate separate with ':'>
|
|
* platform version <platform-id1> files <.sym.txt files containing history data for given platform, separate with ':'>
|
|
* platform version <platform-id2> base <base-platform-id> files <.sym.txt files containing history data for given platform, separate with ':'>
|
|
*
|
|
* The content of platform "<base-platform-id>" is also automatically added to the content of
|
|
* platform "<platform-id2>", unless explicitly excluded in "<platform-id2>"'s .sym.txt files.
|
|
*
|
|
* To create the .sym.txt files, first run the history Probe for all the previous platforms:
|
|
* <jdk-N>/bin/java build.tools.symbolgenerator.Probe <classes-for-N>
|
|
*
|
|
* Where <classes-for-N> is a name of a file into which the classes from the bootclasspath of <jdk-N>
|
|
* will be written.
|
|
*
|
|
* Then create the <platform-description-file> file and the .sym.txt files like this:
|
|
* java build.tools.symbolgenerator.CreateSymbols build-description <target-directory> <path-to-a-JDK-root> <include-list-file>
|
|
* <platform-id1> <target-file-for-platform1> "<none>"
|
|
* <platform-id2> <target-file-for-platform2> <diff-against-platform2>
|
|
* <platform-id3> <target-file-for-platform3> <diff-against-platform3>
|
|
* ...
|
|
*
|
|
* The <include-list-file> is a file that specifies classes that should be included/excluded.
|
|
* Lines that start with '+' represent class or package that should be included, '-' class or package
|
|
* that should be excluded. '/' should be used as package name delimiter, packages should end with '/'.
|
|
* Several include list files may be specified, separated by File.pathSeparator.
|
|
*
|
|
* When <diff-against-platformN> is specified, the .sym.txt files for platform N will only contain
|
|
* differences between platform N and the specified platform. The first platform (denoted F further)
|
|
* that is specified should use literal value "<none>", to have all the APIs of the platform written to
|
|
* the .sym.txt files. If there is an existing platform with full .sym.txt files in the repository,
|
|
* that platform should be used as the first platform to avoid unnecessary changes to the .sym.txt
|
|
* files. The <diff-against-platformN> for platform N should be determined as follows: if N < F, then
|
|
* <diff-against-platformN> should be N + 1. If F < N, then <diff-against-platformN> should be N - 1.
|
|
* If N is a custom/specialized sub-version of another platform N', then <diff-against-platformN> should be N'.
|
|
*
|
|
* To generate the .sym.txt files for OpenJDK 7 and 8:
|
|
* <jdk-7>/bin/java build.tools.symbolgenerator.Probe OpenJDK7.classes
|
|
* <jdk-8>/bin/java build.tools.symbolgenerator.Probe OpenJDK8.classes
|
|
* java build.tools.symbolgenerator.CreateSymbols build-description src/jdk.compiler/share/data/symbols
|
|
* $TOPDIR src/jdk.compiler/share/data/symbols/include.list
|
|
* 8 OpenJDK8.classes '<none>'
|
|
* 7 OpenJDK7.classes 8
|
|
*
|
|
* Note: the versions are expected to be a single character.
|
