伪装libart相同命名空间等相关问题

伪装命名空间问题
// 找到 libart 中调用的 libartbase.so 中的方法 GetCmdLine, 没有特殊含义，仅仅是用来找一个和 libart.so 同一命名空间的函数来伪装身份
xhook_register(".*/libart.so$", "_ZN3art10GetCmdLineEv", NULL, (void **) (&stub_method_in_art),
NULL);

LOGE("stub_method_in_art:%p", stub_method_in_art);

这里打印了stub_method_in_art发现是null，这个对于后面调用libart会不会有影响，实际上测试又看到是有效果的

看到HandleSignal(SIGSEGV)这个会不会影响崩溃捕捉

是否仅对64位架构的大RAM手机运行32位应用的场景有效果？

对于32位的低端设备（RAM较小）本身物理内存不多，缩减RegionSpace仅仅是把有限的空间让给了Native，而Java堆可分配的内存就相应变小了吧
对于64位高端设备，在运行32位应用时，是由于虚拟内存限制在4G以内，导致其无法利用手机空闲的内存，该方案可以多利用部分空间（对应缩减RegionSpace的内存大小）

该方案较适用于：32位且native内存申请较多的应用，特别是运行在64位设备的场景，这样理解对吗

压缩Region Space的地址空间会对Java堆内存分配造成影响吧？

压缩Region Space的地址空间会对Java堆内存分配造成影响吧？
我在demo中尝试压缩到274M之后，然后在Java堆上分配对象，Java堆到160M之后就崩溃了。

反编译工具咨询

请问大佬，这个文章中的反编译工具是什么啊？好像不是ida

Patrons用到的xhook是修改过的吗

你好，想了解下Patrons用到的xhook是修改过的吗，因为安装包大小的原因，打算使用工程里原有的xhook库，结果发现函数的定义与xhook原来的不同，想了解下，Patrons是否对xhook源码进行了修改，如果使用原生的xhook，是否有问题。

只能缓解崩溃吧，另外对gc 速度是否有影响

我的理解是只能缓解崩溃，检测到vss临界点的时候减少region space大小，但是vss仍然是增加，会再次达到大小region space。
但是不能达到就会减少region space大小

另外art gc会不会受到影响，因为目前art gc 几种gc策略都在用，空间减少可能会受到影响吧

在x86的模拟器上会随机崩溃

无java,native堆栈,无明显崩溃日志。已测试mumu及雷电模拟器均会崩溃,Patrons初始化返回的code为2001

non_free_region_index_limit_可以删去，在代码中没有起到作用

[/art/runtime/gc/space/region_space.h]

761   // Invariant (verified by RegionSpace::VerifyNonFreeRegionLimit):
762   //   for all `i >= non_free_region_index_limit_`, `regions_[i].IsFree()` is true.
763   size_t non_free_region_index_limit_ GUARDED_BY(region_lock_);

non_free_region_index_limit_注释中的invariant并非表示这个变量是不变量，注意后面的引号，它指的是762行这个关系式是不变的。实际上non_free_region_index_limit_会在每次CC Collector的ReclaimPhase更新(如下代码所示)，每次回收后都会更新。
而我注意到代码中并没有对non_free_region_index_limit_实时更新，只在init阶段赋值，因此代码中记录的non_free_region_index_limit_是滞后的。

[/art/runtime/gc/collector/concurrent_copying.cc]

2743     {
2744       TimingLogger::ScopedTiming split4("ClearFromSpace", GetTimings());
2745       region_space_->ClearFromSpace(&cleared_bytes, &cleared_objects, /*clear_bitmap*/ !young_gen_);

其实我明白你是为了防止new_size小于Java堆中已用空间的情况。但这种情况已经在RegionSpace::ClampGrowthLimit中的790行做了处理，所以不必担忧。而这个项目里的non_free_region_index_limit_可以删去，因为没有动态更新的话，这个变量的值也就失去了意义。

[/art/runtime/gc/space/region_space.cc]

786 void RegionSpace::ClampGrowthLimit(size_t new_capacity) {
787   MutexLock mu(Thread::Current(), region_lock_);
788   CHECK_LE(new_capacity, NonGrowthLimitCapacity());
789   size_t new_num_regions = new_capacity / kRegionSize;
790   if (non_free_region_index_limit_ > new_num_regions) {
791     LOG(WARNING) << "Couldn't clamp region space as there are regions in use beyond growth limit.";
792     return;
793   }
