| aoqi@0 | 25 | DESCRIPTION |
| aoqi@0 | 26 | |
| aoqi@0 | 27 | This is replacement for CompileTheWorld (CTW) written on java. Its purpose is |
| aoqi@0 | 28 | to make possible the use of CTW in product builds. |
| aoqi@0 | 29 | |
| aoqi@0 | 30 | DEPENDENCES |
| aoqi@0 | 31 | |
| aoqi@0 | 32 | The tool depends on Whitebox API. Assumed, that the sources of whitebox are |
| aoqi@0 | 33 | located in '../whitebox' directory. |
| aoqi@0 | 34 | |
| aoqi@0 | 35 | BUILDING |
| aoqi@0 | 36 | |
| aoqi@0 | 37 | Simple way to build, just type 'make'. |
| aoqi@0 | 38 | |
| aoqi@0 | 39 | Makefile uses environment variables 'ALT_BOOTDIR', 'BOOTDIR' as root-dir of jdk |
| aoqi@0 | 40 | that will be used for compilation and creating jar. |
| aoqi@0 | 41 | |
| aoqi@0 | 42 | On successful building 'ctw.jar' will be created. |
| aoqi@0 | 43 | |
| aoqi@0 | 44 | RUNNING |
| aoqi@0 | 45 | |
| aoqi@0 | 46 | Since the tool uses WhiteBox API, options 'UnlockDiagnosticVMOptions' and |
| aoqi@0 | 47 | 'WhiteBoxAPI' should be specified, and 'wb.jar' should be added to |
| aoqi@0 | 48 | boot-classpath: |
| aoqi@0 | 49 | $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar |
| aoqi@0 | 50 | |
| aoqi@0 | 51 | Arguments can be paths to '.jar, '.zip', '.lst' files or directories with |
| aoqi@0 | 52 | classes, that define which classes will be compiled: |
| aoqi@0 | 53 | - '.jar', '.zip' files and directories are interpreted like in classpath |
| aoqi@0 | 54 | (including '<dir>/*' syntax) |
| aoqi@0 | 55 | - '.lst' files -- files with class names (in java notation) to compile. |
| aoqi@0 | 56 | CTW will try to find these classes with default class loader, so they should |
| aoqi@0 | 57 | be located in classpath. |
| aoqi@0 | 58 | |
| aoqi@0 | 59 | Without arguments it would work as old version of CTW: all classes in |
| aoqi@0 | 60 | boot-classpath will be compiled, excluding classes in 'rt.jar' if 'rt.jar' isn't |
| aoqi@0 | 61 | first in boot-classpath. |
| aoqi@0 | 62 | |
| aoqi@0 | 63 | Due CTW's flags also are not available in product builds, the tool uses |
| aoqi@0 | 64 | properties with the same names: |
| aoqi@0 | 65 | - 'CompileTheWorldPreloadClasses' -- type:boolean, default:true, description: |
| aoqi@0 | 66 | Preload all classes used by a class before start loading |
| aoqi@0 | 67 | - 'CompileTheWorldStartAt' -- type:long, default:1, description: First class |
| aoqi@0 | 68 | to consider |
| aoqi@0 | 69 | - 'CompileTheWorldStopAt' -- type:long, default:Long.MAX_VALUE, description: |
| aoqi@0 | 70 | Last class to consider |
| aoqi@0 | 71 | |
| aoqi@0 | 72 | Also it uses additional properties: |
| aoqi@0 | 73 | - 'sun.hotspot.tools.ctw.verbose' -- type:boolean, default:false, |
| aoqi@0 | 74 | description: Verbose output, adds additional information about compilation |
| aoqi@0 | 75 | - 'sun.hotspot.tools.ctw.logfile' -- type:string, default:null, |
| aoqi@0 | 76 | description: Path to logfile, if it's null, cout will be used. |
| aoqi@0 | 77 | |
| aoqi@0 | 78 | EXAMPLES |
| aoqi@0 | 79 | |
| aoqi@0 | 80 | compile classes from 'rt.jar': |
| aoqi@0 | 81 | $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar ${JAVA_HOME}/jre/lib/rt.jar |
| aoqi@0 | 82 | |
| aoqi@0 | 83 | compile classes from all '.jar' in './testjars' directory: |
| aoqi@0 | 84 | $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar ./testjars/* |
| aoqi@0 | 85 | |
| aoqi@0 | 86 | compile classes from './build/classes' directory: |
| aoqi@0 | 87 | $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar ./build/classes |
| aoqi@0 | 88 | |
| aoqi@0 | 89 | compile only java.lang.String, java.lang.Object classes: |
| aoqi@0 | 90 | $ echo java.lang.String > classes.lst |
| aoqi@0 | 91 | $ echo java.lang.Object >> classes.lst |
| aoqi@0 | 92 | $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar classes.lst |
| aoqi@0 | 93 |
