14 minute read

When you debug asp.net applications it is often useful to find out which requests are currently executing, how long they have been executing, what the query string was etc. Since getting this information from a dump can be a long and tedious process even if you know what you are doing, it lends itself extremely well for a script.

If you are only interested in the script itself, please skip to the last section, but if you’re anything like me, and want to know the nitty gritty details and want to look at some cool features in windbg (the script language and DML=Debugger Markup Language) you might just want to read the whole thing:)

Before we go into the script and its components I just want to mention that I am by no means an expert script-writer so a lot of the code in my script could probably be written a lot better, but it does the job :) feel free to optimize away and send in a new better version in the comments if you feel up to the task…

The second thing I want to mention, and this is always something that is a bit tricky with writing generic debugger scripts, is that I am working a lot with member variable offsets, and offsets change between versions so I will provide one script that works for 2.0.50727.42 and one that works for 2.0.50727.832 along with info on how I got the offsets, so if you get weird output, check your version and fix the offsets…

For the purposes of the discussion I will use the .42 (RTM) offsets

Output and comments on output

The script basically displays info about all the HttpContexts/Requests that are currently on the heap. This means that it displays both requests that are currently running and requests that have finished executing but have yet to be garbage collected.

The following fields are shown…

Field Comment
HttpContext This is just a DML link to the System.Web.HttpContext object in case you need to look at one to get more details
StartTime The time ASP.NET got to the request, you can compare this to the Debug Session Time to figure out how long your request has been executing
Timeout Timeout in seconds, the default is 110 sec. A value of 30000000 indicates that no timeout has been set, which in turn usually means that debug is set to true for this application.
HttpResponse A DML link to the System.Web.HttpResponse object in case you need to look at one to get more details
Completed Yes or No, if Completed is listed as No you will likely find the request executing on one of the threads. To find out which one you can !gcroot the HttpContext object
ReturnCode The HTTP Status code returned to the client
HttpRequest A DML link to the System.Web.HttpRequest object in case you need to look at one to get more details
RequestType POST or GET
URL+QueryString The URL and QueryString of the request

Finding the data

Each request that executes gets a HttpContext which in turn has a link to an ISAPIWorkerRequestInProcForIIS6, a HttpRequest and a HttpResponse.

Extracting the information we want

HttpContext Loop

First off we have to loop through the Contexts on the heap and we do that with the .foreach command. The collection we are looping through is !dumpheap -type System.Web.HttpContext -short which gives us all the addresses to the HttpContexts

.foreach (hc {!dumpheap -type System.Web.HttpContext -short}){
    $$ In here we can use ${hc} to get to the context object
    $$ This is where all the printing will happen
}

With .foreach we split the output of whatever command we pass in on white spaces and put the token into hc in this case. After that we can use the notation ${alias} i.e. ${hc} to avoid that the debugger looks for a symbol to translate hc.

HttpContext with DML

I’m adding an exec DML link to turn the Context address into a link, and when you click it you will run !do <context address>

.printf /D "<?dml?><exec cmd=\"!do ${hc}\">${hc}</exec>\t";

If you want to know more about DML and what you can do with it you should check out the help file dml.doc in the debugging tools directory.

StartTime and TimeOut

If you look at…

Fields:
      MT    Field   Offset                 Type VT     Attr    Value Name
...
7910ca9c  4000f77       8c      System.TimeSpan  1 instance 02c3d844 _timeout
...

you will notice that the VT column is set to 1, the same is true for the _startTime field. Normally when you want to dump out a member variable you will do so by running !dumpobj <value>, and !dumpobj will look at the first DWORD for the MethodTable to figure out how to display it.

ValueType member variables don’t have a header so if we want to dump this out we would have to use !dumpvc <methodtable> <address> to allow sos.dll to figure out how to display it. The first column gives you the <methodtable> to use.

    >> Domain:Value  001a8f88:NotInit  001cb1d8:02b31b48 <<

We are interested in the _ticks value which is a UInt64 stored at offset 0, and we can get this by running dq <TimeSpan address> l1 which gives us 00000000`4190ab00 (the hex equivalent of 1100000000)

0:000> dq 02c3d844 l1
02c3d844  00000000`4190ab00

and then it is just a matter of parsing out the 2nd token of the result and divide this with decimal 10000000 to get a value in seconds since one tick is 100 ns.

Since I don’t know of a better way I am parsing with .foreach by taking the output and skipping the first token (/pS tells .foreach how many tokens to skip initially) and then I take that value and use it in the calculation to get the number of seconds.

0:001> ?00000000`4190ab00/0n10000000
Evaluate expression: 110 = 0000006e

And then finally parse with foreach again skipping the first two tokens to be able to print out the “110”.

the code with some additional fluff to make the output look pretty looks like this.

.foreach /pS 1 /ps 99 (token {dq ${hc}+0x8c l1}){
    .foreach /pS 2 /ps 99 (tk {?${token}/0n10000000}){
        .if (${tk} > 9999){
            .printf "${tk}\t\t"
        }
        .else {
            .printf "${tk}\t\t\t"
        }
    }
};

To get the StartTime we can follow pretty much the same procedure with two important distinctions…

  1. We need to remove the two most significant bytes of ticks/dateData before doing any conversions to time since these bytes contain info about the date format. This is done by performing a bitwise and with 0x3FFFFFFFFFFFFFFF.
  2. To convert it to Time we use formats and pull out token 22, 23 and 24 (Month, Day, Time)

If you’re observant you will probably notice that it says that the request occurred in 3606 :) The real year in this case should have been 2006, but for some reason the time is always off by exactly 1600 years. Anyways, just a curiosity, I’m not using the year anyways in the time output…

Another curiosity is that providing an initial skip to .foreach that is larger than 9 causes no tokens to be returned, so if you are wondering why there are so many nested .foreach statements to parse out the start time, that is why… but again, I don’t really care about how pretty or ugly it looks as long as it works.

The code for the rest of the fields is pretty similar so I’ll leave it up to you to look at the code and figure out the rest. The only thing I wanted to mention is the use of ad /q *… this basically clears out all aliases so that you don’t get errors about redefined aliases if you run the script twice.

Running the Scripts

To run the scripts just copy the code into a text file (dumpallexceptions.wds) and run it with $><c:\tools\extensions\DumpRequests.wds substituting the path for your own.

In order for the scripts to function you must first load sos.dll and preferably run a command like !threads or similar first to avoid any sos loading errors when running !dumpheap -type System.Web.HttpContext -short.

Modifying offsets

If the script doesn’t work and you are running different versions than the ones listed you can find the mt’s of Context, Response and Request in !dumpheap -stat and figure out what the offsets should be for your version.

Hopefully I didn’t mess up the scripts when I edited them for the post but if you get errors please post them and I’ll take a look at them as soon as possible.

Also, if you happen to have some cool scripts laying around and want to share them please add them in the comments. Anything that helps doing tedious work less tedious is really nice :)

Until next time,

Tess

Edit 2020: The scripts are now also available in the Debugging Scripts repo
