openJdk1.8中的makefile，记录下java的执行文件编译过程及jvm编译过程。

目录说明

openjdk源码中有很多目录，根据功能做了模块化划分，每个目录实现其相应的功能。每个目录下的结构都差不多，分为src(源码)、make(makefile)、test(或没有)、其他特殊目录。

openjdk

common 一些公共文件，比如*载下**源码的shell脚本、生成make的autoconf等文件

corba 分布式通讯接口

hotspot 虚拟机实现

jaxp xml处理代码

jaxws ws实现

apijdk jdk源码

langtools java语言工具实现，比如javac、javap等

make make文件

nashorn java中js的运行时实现

test 测试文件

  • Jdk目录 
src 源码目录
bsd bsd实现
linux linux实现
macosx macos实现
share 公用代码，linux平台代*会码**在这里
solaris solaris实现
windows window实现
make makefile
test 单元测试文件

  • langtools目录

该目录主要实现了jdk提供的基于jvm的工具，比如:java, javac, javah, javap等。

langtools
    src 源码目录
          share java源代码
          bin 模板
          classes java源码文件
                     com 存放了java提供的一些基础类实现,打包成tools.jar
                     javax
                     jdk
          sample 样例源码
make makefile目录
test 测试用例目录

Makefile目标生成

可执行文件编译Makefile

文件名为：/openjdk/jdk/make/CompileLaunchers.gmkjava中提供的bin目录下的java、javac、javap等都不是完全通过c/c++编写实现的，是通过c/c++入口，启动虚拟机加载class文件实现的相关功能。通过c/c++的main函数入口，创建jvm虚拟机后，通过执行相关功能的java代码实现其功能，所以java相关的功能如编译、运行、查看jvm信息等功能都是通过启动一个jvm虚拟机或者通过jvmti等实现的。

在makefile文件中可以查看到该部分定义。

具体各个具体功能实现可以由makefile中找到相关的类文件查看实现。这些类在目录langtools目录中。

在linux上编译openjdk的时候，所有java提供的工具程序(bin目录下的可执行程序)入口都是jdk/src/bin/share/bin/main.c。但是具体的功能代码实现其实是在langtools下通过java代码实现的，到底是怎么是怎么实现的呢。1、在jdk/src/share/bin/defines.h中通过宏开关实现了jvm虚拟机执行参数的定义，如下：

#如果定义了JAVA_ARGS宏，则会把jvm的参数从宏定义中获取
# 此处参照/openjdk/jdk/make/CompileLaunchers.gmk文件在声明javac的地方，定义了该宏内容
# -DJAVA_ARGS='{ "-J-ms8m"$(COMMA) "com.sun.tools.javac.Main"$(COMMA) }'))，所以生成的elf文件javac中
# 会得到该值为{ "-J-ms8m"$(COMMA) "com.sun.tools.javac.Main"$(COMMA) }
#ifdef JAVA_ARGS
static const char* const_progname = "java";
static const char* const_jargs[] = JAVA_ARGS;
/*
 * ApplicationHome is prepended to each of these entries; the resulting
 * strings are concatenated (separated by PATH_SEPARATOR) and used as the
 * value of -cp option to the launcher.
 */
#ifndef APP_CLASSPATH
#define APP_CLASSPATH        { "/lib/tools.jar", "/classes" }
#endif /* APP_CLASSPATH */
static const char* const_appclasspath[] = APP_CLASSPATH;
#else  /* !JAVA_ARGS */
#ifdef PROGNAME
static const char* const_progname = PROGNAME;
#else
static char* const_progname = NULL;
#endif
static const char** const_jargs = NULL;
static const char** const_appclasspath = NULL;
#endif /* JAVA_ARGS */

#ifdef LAUNCHER_NAME
static const char* const_launcher = LAUNCHER_NAME;
#else  /* LAUNCHER_NAME */
static char* const_launcher = NULL;
#endif /* LAUNCHER_NAME */

#ifdef EXPAND_CLASSPATH_WILDCARDS
static const jboolean const_cpwildcard = JNI_TRUE;
#else
static const jboolean const_cpwildcard = JNI_FALSE;
#endif /* EXPAND_CLASSPATH_WILDCARDS */

#if defined(NEVER_ACT_AS_SERVER_CLASS_MACHINE)
static const jint const_ergo_class = NEVER_SERVER_CLASS;
#elif defined(ALWAYS_ACT_AS_SERVER_CLASS_MACHINE)
static const jint const_ergo_class = ALWAYS_SERVER_CLASS;
#else
static const jint const_ergo_class = DEFAULT_POLICY;
#endif /* NEVER_ACT_AS_SERVER_CLASS_MACHINE */

最终生成的elf程序常量区段会有程序名称及入口的class类名称。

当使用javac编译java文件时，入口参数1为java文件路径，然后启动一个java虚拟机vm，把com.sun.tools.javac.Main aaa.java传递给java虚拟机vm执行，传递给虚拟机参数如下：

JavaVM args:
    version 0x00010002, ignoreUnrecognized is JNI_FALSE, nOptions is 7
    option[0] = '-Dsun.java.launcher.diag=true'
    option[1] = '-Dapplication.home=/opt/source/jdk8u-dev/build/linux-x86_64-normal-server-slowdebug/jdk'
    option[2] = '-Djava.class.path=/opt/source/jdk8u-dev/build/linux-x86_64-normal-server-slowdebug/jdk/lib/tools.jar:/opt/source/jdk8u-dev/build/linux-x86_64-normal-server-slowdebug/jdk/classes'
    option[3] = '-Xms8m'
    option[4] = '-Dsun.java.command=com.sun.tools.javac.Main aaa.java'
    option[5] = '-Dsun.java.launcher=SUN_STANDARD'
    option[6] = '-Dsun.java.launcher.pid=5997'

  • 2.1 jar包生成

jdk编译后会生成很多jar包，除了jvm虚拟机提供的一些平台功能外，其他语言层面的功能都是由java开发的jar包对外提供的，所以现在有很多语言都基于jvm做了实现。openjdk提供了由运行时rt.jar, 工具tools.jar，编码charset.jar等其他功能jar。下面详细介绍几个重要的jar包是怎么生成的。

tools.jar包

tools.jar包在jdk的lib目录下，主要提供jdk/bin目录下java工具的虚拟机里面的实现代码，由java开发。生成tools.jar包的makefile文件是：文件名为：/openjdk/jdk/make/CreateJars.gmk，内容如下：

rt.jar包

rt.jar包在jdk的lib目录下，主要提供java语言层面的运行时库，由java开发。rt.jar包含的文件范围由:/openjdk/jdk/make/profile-rtjar-includes.txt定义，内容如下:

# Included or excluded types must take one of two forms
# - *.class to indicate all classes; or else
# - a full single type name e.g.
#     com/sun/security/auth/callback/DialogCallbackHandler$1.class
# You can not use arbitrary wildcards like DialogCallbackHandler*.class.
#
# Notes:
# - Nested types must use $ in place of $ as $ is the make meta-character
# - If a package is not listed in any profile's inclusion list then it will
#   not appear in any profile. But if a package is also missing from the
#   full JRE's inclusion list then it will still be part of the full JRE.
#   This is because the full JRE's inclusion lists are only used to define
#   the exclusion lists for profiles; they are not used to define the full
#   JRE contents - that is still done with the pre-profile legacy mechanism
#   (all packagesthat can be found, less those not intended for rt.jar).
#   This was done to minimize the impact of profiles on the regular
#   non-profile build.

jconsole.jar

jconsole.jar包在jdk的lib目录下，是一个Java监视和管理控制台的客户端程序，由javax swing开发。jsoncole可以附加本地java进程，通过api查询方式或者使用jms协议查询java虚拟机一些观测数据。jconsole.jar主要组成由jdk/src/share/classes/sun/tools/jconsole、jdk/src/share/classes/com/sun/tools/jconsole目录下文件组成。

jdk本身提供了2中方式，一种是bin目录下的jconsole程序，另外一种就是lib下的jconsole.jar包。bin下的jsoncole直接运行，启动打开jconsole的main入口， lib下的jsoncole.jar需要使用java -jar jsoncole.jar运行。
