using heapy's memory profile browser with twisted.web

[0] heapy_Use.html #heapykinds.Use.pb

It seems the simplest way to make this information available would be to make a resource in your web server that invokes Use.pb as part of its rendering process. There are other approaches, such as embedding a manhole in your application, or using a signal handler to trigger it, but I like the resource idea. So, for example:

class ProfileBrowser(Resource):
   def render_GET(self, request):
   h.pb()
return "You saw it, right?"

   ...
   root = RootResource(mq)
root.putChild("profile-browser", ProfileBrowser())
   ...

I am trying to profile twisted python code anycodings_heapy with Heapy. For example (pseudo code):,What do I need to do to view Heapy profile anycodings_heapy results in the profile browser?,Load a .csv-file in a dictionary and search for a specific entry in column using Python,After looking over the guppy website and anycodings_heap-memory not finding any information about how to anycodings_heap-memory launch the profile browser there, I anycodings_heap-memory started looking around the guppy source anycodings_heap-memory and eventually found anycodings_heap-memory guppy/heapy/Prof.py, at the end of which anycodings_heap-memory I saw a docstring containing this line:

You can use the HTMLParser class to extract the elements you're interested in. Something like this will work:

from HTMLParser
import HTMLParser "import urllib"
"class AnchorParser(HTMLParser):"
def handle_starttag(self, tag, attrs): "            if tag =='a':"
for key, value in attrs.iteritems()): "                            if key == 'href':"
print value ""
parser = AnchorParser()
"data = urllib.urlopen('http://somewhere').read()"
parser.feed(data)

np.set_printoptions(precision = 4)

new_dataset = dataset[['A', 'D']]

You could use a class decorator (Python 2.6 and up) if you just want to add a common function to several classes (instead of using inheritance).

def addF(y): "    def f(self, x):"
return "Hello", x, "and", y ""
def decorate(cls): "        cls.f = f"
return cls ""
return decorate ""
"@addF(1)"
class X(object): "    pass"
"@addF(2)"
class Y(object): "    pass"
"print X().f("
X ")"
print Y().f("Y")
"" >>> "Hello X and 1"
Hello Y and 2

You can extend the path at runtime like this:

sys.path.extend(map(os.path.abspath, ['other1/', 'other2/', 'yourlib/']))

Using Heapy's Memory Profile Browser with Twisted.web,The example on asp.net of a model binder is:,You can create a <div> (or any plain HTML element) in code behind with the HtmlGenericControl class, and use that to wrap your ImageButton any way you want. For example:,First you'll need server code to access the file system. This is can go inside a code behind file or in the aspx page itself - just delete everything else.

ProfileBase pb = ProfileBase.Create(Page.User.Identity.Name);
m_PreferredName = pb.GetPropertyValue("WebName") as string;

public class GeoPointModelBinder : IModelBinder

        _locations["paris"] = new GeoPoint() { Latitude = 48.856930, Longitude = 2.3412 };

        }

        ValueProviderResult val = bindingContext.ValueProvider.GetValue(

        if (val == null)
        {
            return false;
        }

        string key = val.RawValue as string;
        if (key == null)
        {
            bindingContext.ModelState.AddModelError(
