crashdumper

A cross-platform automated crash report generator/sender for Haxe/OpenFL apps.

Setup

Install crashdumper (coming soon to haxelib, just github for now).

Command Line:
```
haxelib git crashdumper http://github.com/larsiusprime/crashdumper
```
Include crashdumper in your project.xml:
```
<haxelib name="crashdumper"/>
```
Optionally, set one or both of these haxedefs in your project.xml (for cpp targets)
```
<haxedef name="HXCPP_STACK_LINE" />  
<haxedef name="HXCPP_STACK_TRACE"/>  
```
On flash target, stack traces will only be generated in a debug player.

If you don't set the haxedefs, you'll still get a crashdump with a system profile, error message and some other useful info, but you won't get line numbers and a backtrace of the method call stack that led up to the error.

Usage

var unique_id:String = SessionData.generateID("fooApp_"); 
    //generates unique id: "fooApp_YYYY-MM-DD_HH'MM'SS_CRASH"
    
var crashDumper = new CrashDumper(unique_id); 
    //starts the crashDumper

(An example app is provided in the /Example folder)

It will generate something like this:

You may optionally also cache data files (such as a user/player's save game data and/or application config data) at that moment, and the crash report will include verbatim copies of those save files. You can use this to generate a crash report that includes as much data as possible about the user's starting conditions.

Server-Side

CrashDumper can be hooked up to a server-side listener that process and/or stores crash dumps. We are happy to receive any such implementations as pull requests, you can find them all here.

We specifically recommend Crashdump Browser.

Paths

By default will write to your program's application storage directory (SystemPath.applicationStorageDirectory), under /logs/errors/<SESSION_ID>. You can supply your own path, of course.

Performance

Using crashdumper probably comes with a small hit to performance, but it should be much less than the difference between debug and release mode.

HXCPP_STACK_TRACE and HXCPP_STACK_LINE both come with a small hit to performance, but if you're worried about optimization, LINE is the most expensive, TRACE is relatively cheap.

We still need to run performance tests to see what the actual overheads are. We would be more than happy to welcome your benchmark results with crashdumper!
