Stack trace highlighting doesn't work for Mono #320

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The nice stack trace syntax highlighting doesn't work correctly for stack 
traces produced by Mono. I'm assuming the regular expression to match the stack 
frames just needs to be tweaked a bit.

Here is an example stack trace from Mono:

System.Web.HttpException: The controller for path '/helloworld' was not found 
or does not implement IController.
  at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance (System.Web.Routing.RequestContext requestContext, System.Type controllerType) [0x00000] in <filename unknown>:0 
  at System.Web.Mvc.DefaultControllerFactory.CreateController (System.Web.Routing.RequestContext requestContext, System.String controllerName) [0x00000] in <filename unknown>:0 
  at System.Web.Mvc.MvcHandler.ProcessRequestInit (System.Web.HttpContextBase httpContext, IController& controller, IControllerFactory& factory) [0x00000] in <filename unknown>:0 
  at System.Web.Mvc.MvcHandler.BeginProcessRequest (System.Web.HttpContextBase httpContext, System.AsyncCallback callback, System.Object state) [0x00000] in <filename unknown>:0 
  at System.Web.Mvc.MvcHandler.BeginProcessRequest (System.Web.HttpContext httpContext, System.AsyncCallback callback, System.Object state) [0x00000] in <filename unknown>:0 
  at System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.BeginProcessRequest (System.Web.HttpContext context, System.AsyncCallback cb, System.Object extraData) [0x00000] in <filename unknown>:0 
  at System.Web.HttpApplication+<Pipeline>c__Iterator3.MoveNext () [0x00000] in <filename unknown>:0 
  at System.Web.HttpApplication.Tick () [0x00000] in <filename unknown>:0 

Here is how the same stack trace looks from Microsoft .NET:

System.Web.HttpException (0x80004005): The controller for path '/helloworld' 
was not found or does not implement IController.
   at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance((RequestContext requestContext, Type controllerType))
   at System.Web.Mvc.DefaultControllerFactory.CreateController((RequestContext requestContext, String controllerName))
   at System.Web.Mvc.MvcHandler.ProcessRequestInit((HttpContextBase httpContext, IController& controller, IControllerFactory& factory))
   at System.Web.Mvc.MvcHandler.BeginProcessRequest((HttpContextBase httpContext, AsyncCallback callback, Object state))
   at System.Web.Mvc.MvcHandler.BeginProcessRequest((HttpContext httpContext, AsyncCallback callback, Object state))
   at System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.BeginProcessRequest((HttpContext context, AsyncCallback cb, Object extraData))
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute(())
   at System.Web.HttpApplication.ExecuteStep((IExecutionStep step, Boolean& completedSynchronously))

This updated regular expression for ErrorDetailPage seems to work. I haven't 
tested it in the ELMAH code yet but I've tried it in an online regex tester 
(RegexHero) and it seems to work with both Microsoft stack traces and Mono 
stack traces:

                ^
                \s*
                \w+ \s+ 
                (?<type> .+ ) \.
                (?<method> .+? ) 
                (?<params> \( (?<params> .*? ) \) )
                (
                  (?# Microsoft .NET stack traces ) 
                  ( \s+ 
                    \w+ \s+ 
                    (?<file> [a-z] \: .+? ) 
                    \: \w+ \s+ 
                    (?<line> [0-9]+ ) \p{P}? ) 
                  | 

                  (?# Mono stack traces ) 
                  ( \s+
                    \[0x\d+\] \s in \s 
                    <(?<file> [^>]+ )>
                    :(?<line> [0-9]+ )
                  )
                )?
                \s*
                $

Thanks for reporting and helping out with a Regex that works for both 
platforms. Just curious, how are you getting double parentheses in your second, 
Microsoft .NET, stack trace?
IExecutionStep.Execute(())

To be honest, I have no idea. I just copied the message straight from ELMAH.

That's strange... I tried replicating the double parentheses and it's not 
happening any more? I deleted the old database while doing some other dev work 
so don't have a copy of the data with the double parentheses. Oh well.

Screenshot of how it was highlighted by ELMAH is attached.

Thanks for the follow ups. I was going through the regular expression yesterday 
and might have spotted where the double parentheses might be coming from. 
Strange that I have never come across it. Which version are you using and is 
that screenshot coming from ELMAH running on the Mono platform?

Original comment by azizatif on 19 Dec 2012 at 6:59

GoogleCodeExporter commented 9 years ago 
Yes, the screenshot is coming from ELMAH running on Mono. I'm using Mono 3.0.2 
(.NET Framework 4.0) and ELMAH 1.2 SP2 (installed via NuGet).

In that case, I have a feeling that Regex on Mono might be behaving slightly 
differently and is capturing the extra parentheses (yet not always?) but I'll 
double-check that against stack traces in existing logs and on Microsoft .NET 
Framework.

Yeah I've heard the regex engine in Mono sometimes does things a bit 
differently so it could be hitting some edge case in its engine.

I'm happy to beta test any changes if you like :)

The latest version of ELMAH crashes when I try to go to elmah.axd - Looks like 
HttpBrowserCapabilitiesBase.CreateHtmlTextWriter isn't implemented in Mono:

System.NotImplementedException

Should I raise this as a separate bug?

I "fixed" the above issue by not using browser.CreateHtmlTextWriter - That is, 
changing this:
return Render(browser.CreateHtmlTextWriter, items);

To this:
return Render((Func<TextWriter, HtmlTextWriter>)null, items);

In SpeedBar.cs. Not sure if this may break something, but it appears to be 
working. And the syntax highlighting is working too. Screenshot attached :)

I just found an error that appears to get it stuck in a very long loop. Takes a 
long time to render the page in ELMAH (MiniProfiler says 17 seconds on Windows 
and 21 seconds on Linux Mono) and the worker process uses 100% CPU the whole 
time. Happens on both Microsoft .NET and Mono. Here's the stack trace causing 
the problem:
