You can use a EnhancedPatternLayout in log4j to format your stacktraces. See http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/EnhancedPatternLayout.html, specifically the section about the “throwable” pattern in the pattern table. Note that support for the %throwable{n} support is rather new and requires at least log4j 1.2.16 (which is the latest at time of writing) For tracking purposes, this is the ticket … Read more
To get the line numbers in the StackTrace, you need to have the correct debug information (PDB files) alongside your dlls/exes. To generate the the debug information, set the option in Project Properties -> Build -> Advanced -> Debug Info: Setting it to full should suffice (see the Advanced Build Settings Dialog Box docs for … Read more
First off, stack traces don’t do what most people think they do. They can be useful during debugging, but are not intended for runtime use, particularly on ASP.NET. Also, the stack trace is technically about where the code is returning to, not where the code came from. With simple (synchronous) code, the two are the … Read more
See the traceback module, specifically the format_exc() function. Here. import traceback try: raise ValueError except ValueError: tb = traceback.format_exc() else: tb = “No error” finally: print tb
if it ‘s a matter of quantity, you have to recycle your bitmaps. if it’s a matter of size (you can’t load too big images), you have to load a lighter copy of your bitmap. Here is the code to create a smaller image Options thumbOpts = new Options(); thumbOpts.inSampleSize = 4; Bitmap bmp = … Read more
You pass the exception directly to the logger, e.g. try { … } catch (Exception e) { log.error( “failed!”, e ); } It’s up to log4j to render the stack trace.
0 MyApp 0x000833a3 +[TFCrashHandler backtrace] + 26 Crash was generated from +[TFCrashHandler backtrace] + 26; from whatever instruction fell at that symbol location + 26 bytes. If that is really the bottom of your stack trace and it crashed there, then the TCrashHandler is obscuring the real crash. The real crash looks to be a … Read more
Throwing twice in the same method is probably a special case – I’ve not been able to create a stack trace where different lines in the same method follow each other. As the word says, a “stack trace” shows you the stack frames that an exception traversed. And there is only one stack frame per … Read more
I don’t believe this is possible using the standard Java API. What you could do is to use AspectJ, place a point-cut at the calling method, save the arguments, place a point-cut at the called method and pass on the arguments. Another option (slightly more advanced) is to use a custom, bytecode-rewriting, class loader that … Read more
Xdebug prints a backtrace table on errors, and you don’t have to write any PHP code to implement it. Downside is you have to install it as a PHP extension.
