  • Finding cause of memory leaks in large PHP stacks

    - by Mike B
    I have CLI script that runs over several thousand iterations between runs and it appears to have a memory leak. I'm using a tweaked version of Zend Framework with Smarty for view templating and each iteration uses several MB worth of code. The first run immediately uses nearly 8MB of memory (which is fine) but every following run adds about 80kb. My main loop looks like this (very simplified) $users = UsersModel::getUsers(); foreach($users as $user) { $obj = new doSomethingAwesome(); $obj->run($user); $obj = null; unset($obj); } The point is that everything in scope should be unset and the memory freed. My understanding is that PHP runs through its garbage collection process at it's own desire but it does so at the end of functions/methods/scripts. So something must be leaking memory inside doSomethingAwesome() but as I said it is a huge stack of code. Ideally, I would love to find some sort of tool that displayed all my variables no matter the scope at some point during execution. Some sort of symbol-table viewer for php. Does anything like that or any other tools that could help nail down memory leaks in php exist?

  • JUnit4 + Eclipse "An internal error occured during Launching"

    - by Mike
    Hello I'm trying to run JUnit4 test cases on Eclipse 3.4.2 but it's not even starting for me. I am sure that I properly have junit-4.7.jar in my build path and the test application. Here is a simple example that illustrates my problem package test; import org.junit.Before; import org.junit.Test; public class UTest { @Test public void test() { } @Before public void setUp() throws Exception { } } This compiles fine Then I do "Run JUnit Test case" from Eclipse and I get an error dialog with this message "Launching UTest' has encountered a problem An internal error occurred during: "Launching UTest". java.lang.NullPointerException I'm not sure how to figure out what exactly generating this NullPointerException. Some pointers would be appreciated

  • Updating only .dll of a reference in my ASP.NET Application

    - by Mike C.
    Hello, I have a deployed web application project that references my Utility.dll class library. I want to make a change to the Utlity.dll and roll only that .dll out. The problem is that when I do that, I get the following error when I try to launch my site: Could not load file or assembly 'Utility, Version=1.0.0.0, Culture=neutral, PublicKeyToken=3766481cef20a9d1' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) Is there a setting I can change so I don't have to roll out the entire web application project - only the Utlity.dll? Thanks!

  • Android Apps Not Showing Up In AVD

    - by Mike
    I recently started messing with Android Apps, but I have had nothing but problems trying to get them into the Virtual Device for testing. For some reason, they never seem to show up in the AVD. It has worked one time, but that's it out of hours spent just trying to test one or two very simple apps. I've redone the AVD setup many, many times, trying different settings and what not to no avail. I've followed multiple guides and tutorials to the letter to get it working, but they just refuse to show up in the list. :( Any insight would be appreciated, thank you.

  • How to get site context/information during the PreapplicationStartMethod

    - by Mike
    When you run the same web based application as a multi-tenant application for different clients is there a way during the PreapplicationStartMethod to gain some kind of context to the site that is being started? More specifically I'd like to get the host header information (the "bindingInformation" attribute value from the applicationHost.config); I have found ways to get this information at the time of a specific request long after the application has started. Is there a way to get the information during the application startup process? This is an MVC 3 application and IIS 7.5.

  • How to call a method withgin a vector?

    - by Mike Dooley
    Hi! How do I call a method of an object which is stored within a vector? The following code fails... ClassA* class_derived_a = new ClassDerivedA; ClassA* class_another_a = new ClassAnotherDerivedA; vector<ClassA*> test_vector; test_vector.push_back(class_derived_a); test_vector.push_back(class_another_a); for (vector<ClassA*>::iterator it = test_vector.begin(); it != test_vector.end(); it++) it->printOutput(); The code retrieves the following error: test3.cpp:47: error: request for member ‘printOutput’ in ‘* it.__gnu_cxx::__normal_iterator<_Iterator, _Container::operator- with _Iterator = ClassA**, _Container = std::vector ’, which is of non-class type ‘ClassA*’ The problem seems to be it->printOutput(); but at the moment I don't know how to call the method properly, does anyone know? regards mikey

  • How can I include .pdf files when I publish but not in a search and replace in visual studio?

    - by Mike
    More specifically my problem is if I include a pdf in my project and set its build action to content so it gets copied to the server when I publish, is there a way to exclude it from visual studios search and replace feature. Would a post build action be a solution to this? I just don't want anybody to do a global search and replace in my project and mess up the pdfs... I know I just said a mouth full so let me know if you need clarification. Thanks!!!

  • Visual Studio keeps running the old build

    - by Mike Pike
    Hello. I have a simple Silverlight program that displays a bunch of images. I modified it do display more images, but it when I hit "run without debugging" is keeps running the old build with fewer images. When I copy the code into a new project and run it, it works fine for the first time, but then each subsequent change is not displayed. What could be the problem? I'm using Visual Web Developer 2008 Express.

  • Remove adjacent identical elements in a Ruby Array?

    - by Mike Woodhouse
    Ruby 1.8.6 I have an array containing numerical values. I want to reduce it such that sequences of the same value are reduced to a single instance of that value. So I want a = [1, 1, 1, 2, 2, 3, 3, 3, 3, 2, 2, 2, 3, 3, 3] to reduce to [1, 2, 3, 2, 3] As you can see, Array#uniq won't work in this case. I have the following, which works: (a.size - 1).downto(1) { |i| a[i] = nil if a[i - 1] == a[i] } Can anyone come up with something less ugly?

  • How is this Perl code selecting two different elements from an array?

    - by Mike
    I have inherited some code from a guy whose favorite past time was to shorten every line to its absolute minimum (and sometimes only to make it look cool). His code is hard to understand but I managed to understand (and rewrite) most of it. Now I have stumbled on a piece of code which, no matter how hard I try, I cannot understand. my @heads = grep {s/\.txt$//} OSA::Fast::IO::Ls->ls($SysKey,'fo','osr/tiparlo',qr{^\d+\.txt$}) || (); my @selected_heads = (); for my $i (0..1) { $selected_heads[$i] = int rand scalar @heads; for my $j (0..@heads-1) { last if (!grep $j eq $_, @selected_heads[0..$i-1]); $selected_heads[$i] = ($selected_heads[$i] + 1) % @heads; #WTF? } my $head_nr = sprintf "%04d", $i; OSA::Fast::IO::Cp->cp($SysKey,'',"osr/tiparlo/$heads[$selected_heads[$i]].txt","$recdir/heads/$head_nr.txt"); OSA::Fast::IO::Cp->cp($SysKey,'',"osr/tiparlo/$heads[$selected_heads[$i]].cache","$recdir/heads/$head_nr.cache"); } From what I can understand, this is supposed to be some kind of randomizer, but I never saw a more complex way to achieve randomness. Or are my assumptions wrong? At least, that's what this code is supposed to do. Select 2 random files and copy them. === NOTES === The OSA Framework is a Framework of our own. They are named after their UNIX counterparts and do some basic testing so that the application does not need to bother with that.

  • Combining 2 Linq queries into 1

    - by Mike Fielden
    Given the following information, how can I combine these 2 linq queries into 1. Having a bit of trouble with the join statement. 'projectDetails' is just a list of ProjectDetails ProjectDetails (1 to many) PCardAuthorizations ProjectDetails (1 to many) ExpenditureDetails Notice I am grouping by the same information and selecting the same type of information var pCardAccount = from c in PCardAuthorizations where projectDetails.Contains(c.ProjectDetail) && c.RequestStatusId == 2 group c by new { c.ProjectDetail, c.ProgramFund } into g select new { Key = g.Key, Sum = g.Sum(x => x.Amount) }; var expenditures = from d in ExpenditureDetails where projectDetails.Contains(d.ProjectDetails) && d.Expenditures.ExpenditureTypeEnum == 0 group d by new { d.ProjectDetails, d.ProgramFunds } into g select new { Key = g.Key, Sum = g.Sum(y => y.ExpenditureAmounts.FirstOrDefault(a => a.IsCurrent && !a.RequiresAudit).CommittedMonthlyRecords.ProjectedEac) };

  • Javascript how can I trigger an event that was prevented

    - by Mike Robinson
    In my app a user clicks a link to another page. I'd like to track that in Omniture with a custom event, so I've bound the omniture s.t() event to the click event. How can I make certain the event fires before the next page is requested? I've considered event.preventDefault() on the click event of the link, but I actually want the original event to occur, just not immediately.

  • How can I retrieve the values of controls in the form that posted?

    - by Mike at KBS
    I know this has got to be the simplest-sounding question ever asked about ASP.Net but I'm baffled. I have a form wherein my visitor will enter name, address, etc. Then I am POSTing that form via the PostBackUrl property of my Submit button to another page, where the fields are supposed to be all re-formed into new hidden fields, then POSTed again to Paypal. My problem is I cannot get at the values entered by the visitor in the original page. Any time I put in "runat='server'", ASP.Net completely changes the ID of the control, making it impossible to figure out how to access. In the POSTed form I tried Request.Form["_txtFirstName"] and that turned up null. Then I tried ((TextBox)PreviousPage.FindControl("_txtFirstName")).Text and that was null, too. I've tried variations on those. I cannot figure out how I'm supposed to get at these controls. Why does this stuff need to be so difficult?

  • php, get an end date based on start date and number of months

    - by mike
    Hi! I need to calculate an end date based on todays date and a number of months. For example, todays date 04/01/2010 and the number of months is 6. Are there any functions I can use to do some math that would return "10/01/2010"? Also, I think it's important to note that I am storing the result in MySQL as a "DATETIME" so I guess I would have to do something with the time as well... ??? Thanks!

  • How can I tell Phusion Passenger which python to use?

    - by Mike
    I'm using Phusion Passenger with a ruby app and I'd also like to set it up to work with an django appengine app I'm working on. Googling for "passenger_wsgi.py" I was able to get the following very simple non-django app working on passenger: passenger_wsgi.py: def application(environ, start_response): response_headers = [('Content-type','text/plain')] start_response('200 OK', response_headers) return ['Hello World!\n'] However, if I add the line import django.core.handlers.wsgi into the mix, I get 'An error occurred importing your passenger_wsgi.py'. By printing out the sys.path I've discovered that at least part of the reason is because Passenger is using the wrong python installation on my machine. How can I configure Passenger (on apache) to use /opt/local/bin/python2.5 instead of the system default python?
