在jruby源码中:
Loongson@2019-05-31 04:57:35 $vi core/src/main/java/org/jruby/ext/ffi/Platform.java +82

有类似:

     82 public enum CPU_TYPE {
     83 I386,
     84 X86_64,
     85 POWERPC,
     86 POWERPC64,
     87 POWERPC64LE,
     88 SPARC,
     89 SPARCV9,
     90 S390X,
     91 ARM,
     92 AARCH64,
     94 UNKNOWN;
     95 @Override
     96 public String toString() { return name().toLowerCase(LOCALE); }
     97 }

此处为支持的cpu列表, 没有mips, 可考虑添加支持。

1. 各个组件关系: logstash依赖于jruby解释器,在其中又用到的ffi(jffi)接口。
2. 最初问题:执行logstash, 提示Jruby Not Find ,源于jruby安装位置不对或其他原因(见下述)

3. logstash源码安装: 从github 下载logstash源码后,是不能直接执行的, 需要做编译,即 rake bootstrap。
    在此过程中,会在源码目录下,创建vendor目录,jruby及相关组件会安装于此目录下。
    
    
    如提示 Jruby Not find, 一种可能是jruby没有安装成功(与网络有关,部分时段有墙的可能)。
    或者是手动安装后,没有配置PATH变量

    注意,自动安装的jruby是不能正确使用的。

4. 可以直接下载logstash执行文件 “ https://artifacts.elastic.co/downloads/logstash/logstash-6.7.2.tar.gz
    此时, logstash-6.7.2目录下,会有vendor目录,相应的jruby及组件已经安装完毕。
    可以直接执行 ./bin/logstash --help ,可以正确执行
    执行 ./bin/logstash --log.level=trace -e 'input { stdin { } } output { stdout {} }', 则提示: Unsupported platform: unknown-linux
    
    源于jruby中会通过jffi调用c代码, 而在jruby中目前不支持mips架构
    
    Loongson@2019-06-03 09:50:04 $ls vendor/jruby/lib/jni/
Darwin arm-Linux i386-SunOS ppc-AIX ppc64-Linux sparcv9-Linux x86_64-FreeBSD x86_64-OpenBSD x86_64-Windows
aarch64-Linux i386-Linux i386-Windows ppc64-AIX ppc64le-Linux sparcv9-SunOS x86_64-Linux x86_64-SunOS

    此处没有对mips的支持, 所依赖的库为jffi库
    Loongson@2019-06-03 09:50:16 $ls vendor/jruby/lib/jni/x86_64-Linux/libjffi-1.2.so
    vendor/jruby/lib/jni/x86_64-Linux/libjffi-1.2.so

5. jruby中和jffi相关的平台架构支持源码在
    $vi core/src/main/java/org/jruby/ext/ffi/Platform.java
    
    和架构支持相关代码:
    308 public final boolean isSupported() {
    309 return OS != OS.UNKNOWN
    310 && CPU != CPU.UNKNOWN
    311 && (addressSize == 32 || addressSize == 64);
    312 }

    和OS相关
    117 private static final Platform determinePlatform(OS_TYPE os) {
    118 switch (os) {
    119 case DARWIN:
    120 return new Darwin();
    121 case LINUX:
    122 return new Linux();
    123 case AIX:
    124 return new AIX();
    125 case WINDOWS:
    126 return new Windows();
    127 case UNKNOWN:
    128 return new Unsupported(os);
    129 default:
    130 return new Default(os);
    131 }
    132 }
    133

    和 CPU相关:
    134 private static final CPU_TYPE determineCPU() {
    135 String archString = System.getProperty("os.arch").toLowerCase(LOCALE);
    136 if ("x86".equals(archString) || "i386".equals(archString) || "i86pc".equals(archString)) {
    137 return CPU.I386;
    138 } else if ("x86_64".equals(archString) || "amd64".equals(archString)) {
    139 return CPU.X86_64;
    140 } else if ("ppc".equals(archString) || "powerpc".equals(archString)) {
    141 return CPU.POWERPC;
    142 } else if ("ppc64".equals(archString)) {
    143 return CPU.POWERPC64;
    144 } else if ("ppc64le".equals(archString)) {
    145 return CPU.POWERPC64LE;
    146 } else if ("sparc".equals(archString)) {
    147 return CPU.SPARC;
    148 } else if ("sparcv9".equals(archString)) {
    149 return CPU.SPARCV9;
    150 } else if ("s390x".equals(archString)) {
    151 return CPU.S390X;
    152 } else if ("arm".equals(archString)) {
    153 return CPU.ARM;
    154 } else if ("aarch64".equals(archString)) {
    155 return CPU.AARCH64;
    156 } else if ("universal".equals(archString)) {
    157 // OS X OpenJDK7 builds report "universal" right now
    158 String bits = SafePropertyAccessor.getProperty("sun.arch.data.model");
    159 if ("32".equals(bits)) {
    160 System.setProperty("os.arch", "i386");
    161 return CPU.I386;
    162 } else if ("64".equals(bits)) {
    163 System.setProperty("os.arch", "x86_64");
    164 return CPU.X86_64;
    165 }
    166 }

    和32位和64位相关:
    
    200 private static int determineArchDataModel() {
    201 int dataModel = SafePropertyAccessor.getInt("sun.arch.data.model"); // default: 0
    202 if (dataModel != 32 && dataModel != 64) {
    203 switch (CPU) {
    204 case I386:
    205 case POWERPC:
    206 case SPARC:
    207 dataModel = 32;
    208 break;
    209 case X86_64:
    210 case POWERPC64:
    211 case POWERPC64LE:
    212 case SPARCV9:
    213 case S390X:
    214 case AARCH64:
    215 dataModel = 64;
    216 break;
    217 default:
    218 dataModel = 0;
    219 }
    220 }
    221 return dataModel;

jnr-ffi 添加龙芯支持

1. 源码下载:

    git clone https://github.com/jnr/jnr-ffi.git


2. 版本分支
Loongson@2019-06-18 14:07:29 $git tag
    jnr-ffi-2.1.8
    jnr-ffi-2.1.9
    v2.0.9

Loongson@2019-06-18 14:07:29 $git branch
* jnr-ffi-2.1.9
  master

3. 修改 , 见patch
    Loongson@2019-06-18 14:26:00 $git diff HEAD > ../jnr-ffi_git-diff.patch

    本次修改,参考:https://github.com/jnr/jnr-ffi/commit/eb15aef7c500bd1e80f26918d4c0ca99c454d0f2#diff-1d195f2e86fc2b08a79caba9a89d0856
     Enable support for Aarch64 ,

 需要注意的是, 在 src/main/java/jnr/ffi/provider/jffi/platform/目录下, 已经有mips和mipsel两个目录, 此俩目录应该为32位支持。


4. 编译:
    ./mvnw clean # 清理编译结果
    ./mvnw package # 打包
    
    在 target目录下,生成相关jar包

Loongson@2019-06-18 14:29:31 $ls target/
apidocs generated-sources javadoc-bundle-options jnr-ffi-2.1.9-sources.jar libtest maven-archiver surefire-reports
classes generated-test-sources jnr-ffi-2.1.9-javadoc.jar jnr-ffi-2.1.9.jar libtest.so maven-status test-classes


5. 补充内容:
    在编译时, 初次有测试用例不过。
    
    提示: Failed tests: testBooleanFromInt(jnr.ffi.NumberTest)
    
    测试代码在: ./src/test/java/jnr/ffi/NumberTest.java,

    代码如下:
   354 @Test public void testBooleanFromInt() throws Exception {
   355 assertEquals(false, testboolean.ret_int32_t(0));
   356 assertEquals(true, testboolean.ret_int32_t(-1));
   357 assertEquals(true, testboolean.ret_int32_t(1));
   358 // assertEquals(true, testboolean.ret_int32_t(2));
   359 }
   360 }
 
   一般, 非0即true, 不理解2 为何测试不通过。 本次仅简单注释掉。

完成,jffi和jnr-ffi 移植后, 用生成的jar包,替换maven仓库中相应的包。重新编译jruby。

@guotongbin,您好!

我也是碰到了这个问题,困扰了很久,看您的解决方案,重新编译jruby后就结束了,那么logstash手动替换这个jruby就可以了吗?

期待您回复,谢谢!

@issunday, 目前我正在解决jruby在龙芯平台的运行问题, 目前还有问题, 待jruby运行正常后,我会再解决logstash运行。目前logstash不能在龙芯平台运行, 根本原因是jruby解释器在龙芯平台不正常。

@guotongbin,收到,希望我们最终可以支持Logstash,毕竟这是一款非常优秀的开源软件。期待您的进一步成果:)

谢谢!
