如何读取Xcode 6.1 Instruments .trace文件? [英] How to read a Xcode 6.1 Instruments .trace file?

问题描述

我一直在尝试读取.trace文件，该文件是使用 custom 工具模板生成的(仪器: Automator ，分配 >，泄漏)，使用

I have been trying to read a .trace file, which I had generated using a custom instruments template(instruments: Automator, Allocations, Leaks) using Instruments.

在此 stackoverflow答案中找到的最佳帮助.基本上，作者创建了一个自定义的 Objective-C 程序(

The best help I found in this stackoverflow answer. Basically the author created a custom Objective-C program(Traced) to read a specific type of Apples .trace file(instrument: OpenGL ES Driver). His answer is geared towards XCode 4.6.

该代码仍可与 XCode 6.1 一起使用，但是跟踪文件似乎已略有更改.您必须在.trace包中找到*.run.zip文件并将其解压缩.现在，在解压缩的文件夹中，您必须找到*.run文件. .trace程序包中有几个*.run.zip文件.每个使用过的乐器一个.

The code still works with XCode 6.1, but the trace-file seems to have changed slightly. You have to find the *.run.zip file within the .trace package and unzip it. In the extracted folder you now have to find the *.run file. There are several *.run.zip files in a .trace package; one per used instrument.

仅运行跟踪程序，就会出现uncaught exception 'NSArchiverArchiveInconsistency', reason: '*** class error for 'XRObjectAllocRun'-错误.

Simply running the Traced program got me a uncaught exception 'NSArchiverArchiveInconsistency', reason: '*** class error for 'XRObjectAllocRun'-error.

此错误最初很容易弄清楚.我要做的就是实现缺少的类XRObjectAllocRun；平行于XRRun或XRVideoCardRun类.

This error was initially easy to figure out. All I had to do was implement the missing class XRObjectAllocRun; parallel to the example XRRun or XRVideoCardRun classes in XRRun.m.

这是我走多远，我被困住的地方:

This is how far I got and where I got stuck:

#import "XRObjectAllocRun.h"

@implementation XRObjectAllocRun
- (id)initWithCoder:(NSCoder *)decoder
{
    if((self = [super init]))
    {   
        NSObject *a = [decoder decodeObject];
        NSObject *b = [decoder decodeObject];
        NSObject *c = [decoder decodeObject];
        NSObject *d = [decoder decodeObject];
        NSObject *e = [decoder decodeObject];
        NSObject *f = [decoder decodeObject];
        NSObject *g = [decoder decodeObject];
        NSObject *h = [decoder decodeObject];
        NSObject *i = [decoder decodeObject];
//        NSObject *j = [decoder decodeObject];
//        NSObject *k = [decoder decodeObject];   
        NSLog(@"test");
    }
    return self;
}
@end

基本上，我受困于反向工程 XRObjectAllocRun类.但是无论我解码多少个对象，我总是会收到以下异常:uncaught exception 'NSArchiverArchiveInconsistency', reason: '*** NSUnarchiver: inconsistency between written and read data for object 0x100112750'

Basically I am stuck reverse-engineering the XRObjectAllocRun class. But no matter how many or little objects I decode I always receive the following exception: uncaught exception 'NSArchiverArchiveInconsistency', reason: '*** NSUnarchiver: inconsistency between written and read data for object 0x100112750'

如果您取消对最后两个decode语句的注释，程序将因以下异常而崩溃:uncaught exception 'NSArchiverArchiveInconsistency', reason: '*** file inconsistency: read 'i', expecting '@''.

If you uncomment the last two decode statements the program will crash with this exception: uncaught exception 'NSArchiverArchiveInconsistency', reason: '*** file inconsistency: read 'i', expecting '@''.

有人知道Apple XRObjectAllocRun类的签名吗?此类用于分配工具.

Does anyone know the signature of Apples XRObjectAllocRun class? This class is used for the Allocations instrument.

任何帮助都会很棒！

更新

我玩过 Swift 并翻译了整个*.trace -reader-它失败并出现完全相同的错误:

I played around with Swift and translated the entire *.trace-reader - it fails with exactly the same error(s):

import Foundation
import Cocoa

@objc(XRObjectAllocRun)
class XRObjectAllocRun: NSObject {
    func initWithCoder(decoder:NSCoder){
        var x = decoder.decodeObject()
        // this is where things start breaking...
    }
}

@objc(XRRun)
class XRRun: NSObject {
    // to be implemented    
}

@objc(XRTrackSegment)
class XRTrackSegment: NSObject {
    func initWithCoder(decoder:NSCoder)->NSString{
        var a = decoder.decodeObject()?.integerValue
        var b = decoder.decodeObject()?.integerValue
        var c = decoder.decodeObject()?.integerValue
        var d = decoder.decodeObject()?.integerValue
        var e = decoder.decodeObject()

        return "test"
    }
}

@objc(PFTTrackSegment)
class PFTTrackSegment: NSObject {
    func initWithCoder(decoder:NSCoder){
        var a = decoder.decodeObject()?.integerValue
        var b = decoder.decodeObject()?.integerValue
        var c = decoder.decodeObject()?.integerValue
        var d = decoder.decodeObject()?.integerValue
        var e = decoder.decodeObject()?.integerValue
        var f = decoder.decodeObject()?.integerValue
    }
}

// parse command line
var traceFilePath = Process.arguments[1]
println("input: \(traceFilePath)")

var traceFile = NSURL(fileURLWithPath: traceFilePath)
var error:NSError?

// check if the file exists
if (traceFile?.checkResourceIsReachableAndReturnError(&error) == false){
    // file does not exist or cannot be accessed
    println("\(error)")
    exit(1)
}

var rawData = NSData(contentsOfURL: traceFile!)
var data = NSUnarchiver(forReadingWithData: rawData!)
var decodedObject: AnyObject? = data?.decodeObject()
println("\(decodedObject)")

我已经在此处上传了其他类的签名您需要它们.

I've uploaded signatures of other classes here if you need them.

您无需在Swift中声明必需的类，而只需将头文件从归档文件导入桥接头文件即可.

Instead of declaring required classes in Swift, you can simply import headers from the archive to the bridging header.
