Atos没有正确地表示系统框架/库 [英] Atos does not symbolicate system frameworks/libraries properly
问题描述
问题在于，当PLCrashReporter报告的堆栈跟踪地址符号化时，不会返回实际的系统框架/库符号行。我的应用程序行虽然显示了符号化的正确违规行。
The problem is that when symbolicating the stacktrace addresses reported by PLCrashReporter doesn't return the actual system frameworks/libraries symbolicated line. My application line is though showing the correct offending line symbolicated.
某些配置。我在我的OSX 10.9.5上安装了Xcode 5.1.1和Xcode 6.0.1。
Some configuration. I have on my OSX 10.9.5 installed the Xcode 5.1.1 and Xcode 6.0.1.
使用Xcode 5.1.1并检查设备日志时，我可以看到崩溃，尽管崩溃报告中不会发生任何符号化。
When working with the Xcode 5.1.1 and examine the device log I can see the crashes although no symbolication can take place in the crash report.
使用Xcode 6.0.1崩溃我的应用程序并检查设备日志我可以看到报告符号正确。
Using Xcode 6.0.1 crashing my app and examine the device log I can see the report symbolicated properly.
Atos在任何情况下都不会返回正确的Apple系统框架/库符号行。它只返回与相应框架/库无关的垃圾。请参阅下面的示例。
Atos in any case does not return the correct Apple system frameworks/libraries symbolicated line. It just return garbages, classes that has nothing to do with the corresponding framework/library. See below for examples.
详细说明我使用PLCrashReporter向我报告的崩溃堆栈跟踪，并与设备日志符号化报告进行比较。
In detail what I do to symbolicate my crash stacktrace reported to me using the PLCrashReporter and comparing to the device log symbolicated report.
以下是使用PLC未示出的PLCrashReporter报告的堆栈跟踪：

以上是PLCrashReported上面的堆栈跟踪，使用xcrun atos符号表示：
Here is the stacktrace above from PLCrashReported symbolicated using "xcrun atos":

以下是符号设备日志上面完全崩溃的堆栈跟踪：
Here is the stacktrace of the above same exact crash from the device log symbolicated:
0 libsystem_platform.dylib 0x000000019726ce5c _platform_memmove + 188

您可以看到两个符号化的堆栈跟踪，首先来自PLCrashReporter堆栈跟踪，第二个来自Xcode设备日志。我想在这一点上说，我不相信这是有问题的地址，但更多的事情与atos一起发生。
Xcode是否使用symbolicatecrash工具来表示Apple报告？
You can see the two symbolicated stacktraces, first from PLCrashReporter stacktrace and second from the Xcode device log. I would like in this point to say that I don't believe it's the addresses that has the problem but more something going on with atos. Is Xcode using the symbolicatecrash tool to symbolicate the Apple report?
atos命令： xcrun atos -arch arm64 -o MyNewPlugin。 app.dSYM / Contents / Resources / DWARF / MyNewPlugin -l 0x197268000 0x000000019726ce5c 将导致 _mh_execute_header（在MyNewPlugin中）+ 20060 这是完全错误的它应该返回类似设备日志报告的内容 _platform_memmove + 188 。
The atos command: xcrun atos -arch arm64 -o MyNewPlugin.app.dSYM/Contents/Resources/DWARF/MyNewPlugin -l 0x197268000 0x000000019726ce5c will result to _mh_execute_header (in MyNewPlugin) + 20060 which is completely wrong and it should return something like the device log report _platform_memmove + 188.
另一个atos示例来证明行的问题3.
xcrun atos -arch arm64 -o MyNewPlugin.app.dSYM / Contents / Resources / DWARF / MyNewPlugin -l 0x18d5b0000 0x000000018d5f90b0 ，
应返回， UIKit 0x000000018d5f90ac - [UIApplication sendAction：to：from：forEvent：] + 96 ，
代替返回， UIKit __30- [RequestWorker logEvent ：] _ block_invoke（在MyNewPlugin中）+ 232 与UIKit无关，这是我使用的内部类。
Another atos example to prove the problem for line 3.
xcrun atos -arch arm64 -o MyNewPlugin.app.dSYM/Contents/Resources/DWARF/MyNewPlugin -l 0x18d5b0000 0x000000018d5f90b0,
should return, UIKit 0x000000018d5f90ac -[UIApplication sendAction:to:from:forEvent:] + 96,
instead returns, UIKit __30-[RequestWorker logEvent:]_block_invoke (in MyNewPlugin) + 232 which has nothing to do with UIKit, this is an internal class I use.
这是怎么回事我创建了stacktra的行使用PLCrashReporter。
This is how I create the lines of the stacktrace using PLCrashReporter.
[NSString stringWithFormat:@"%-4ld%@ 0x0000000%" PRIx64 " 0x%" PRIx64 " + %" PRId64 "", (long)frameIndex, imageName, frameInfo.instructionPointer, baseAddress, pcOffset];
编辑：
在终端中使用symbolicatecrash进行非符号化苹果崩溃报告象征着所有的系统组件而不是应用程序线!!!
Using symbolicatecrash in the terminal for the unsymbolicated apple crash report is symbolicating all system assemblies but not the application lines!!!
推荐答案
答案很简单，但有时你不喜欢不要在你面前看到它。
The answer was so simple but sometimes you don't see it in front of you.
你不需要使用应用程序的dSYM，而是使用设备在崩溃时拥有的iOS版本的框架。例如对于iOS 8.1.1的UIKit符号
Instead of using the application's dSYM you use the framework of the iOS version that the device has when crashed. e.g. for the UIKit symbols of the iOS 8.1.1
xcrun atos -arch arm64 -o~ / Library / Developer / Xcode / iOS DeviceSupport / 8.1.1（12B436）/符号/系统/库/框架/ UIKit.framework / UIKit -l 0x18d5b0000 0x000000018d5f90b0
xcrun atos -arch arm64 -o ~/Library/Developer/Xcode/iOS DeviceSupport/8.1.1 (12B436)/Symbols/System/Library/Frameworks/UIKit.framework/UIKit -l 0x18d5b0000 0x000000018d5f90b0
这篇关于Atos没有正确地表示系统框架/库的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
