  • Integration tests - "no exceptions are thrown" approach. Does it make sense?

    - by Andrew Florko
    Sometimes integration tests are rather complex to write or developers have no enough time to check output - does it make sense to write tests that make sure "no exceptions are thrown" only? Such tests provide some input parameters set(s) and doesn't check the result, but only make sure code not failed with exception? May be such tests are not very useful but appropriate in situations when you have no time?

  • Perl 500 internal server error. Something wrong with my code.

    - by Nitish
    I get a 500 internal server error when I try to run the code below in a web server which supports perl: #! /usr/bin/perl use LWP; my $ua = LWP::UserAgent->new; $ua->agent("TestApp/0.1 "); $ua->env_proxy(); my $req = HTTP::Request->new(POST => 'http://www.google.com/loc/json'); $req->content_type('application/jsonrequest'); $req->content('{ "cell_towers": [{"location_area_code": "55000", "mobile_network_code": "95", "cell_id": "20491", "mobile_country_code": "404"}], "version": "1.1.0", "request_address": "true"}'); my $res = $ua->request($req); if ($res->is_success) { print $res->content,"\n"; } else { print $res->status_line, "\n"; return undef; } But there is no error when I run the code below: #! /usr/bin/perl use CGI::Carp qw(fatalsToBrowser); print "Content-type: text/html\n\n"; print "<HTML>\n"; print "<HEAD><TITLE>Hello World!</TITLE></HEAD>\n"; print "<BODY>\n"; print "<H2>Hello World!</H2> <br /> \n"; foreach $key (sort keys(%ENV)) { print "$key = $ENV{$key}<p>" ; } print "</BODY>\n"; print "</HTML>\n"; So I think there is some problem with my code. When I run the first perl script in my local machine with the -wc command, it says that the syntax is OK. Help me please.

  • HTTPS post - what I'm doing wrong?

    - by evilone
    Hi, I'm making requests to the webaddress to get XML files throught the HTTPS connection. But this connection works like 50%. In most cases it fails. Usual error is "socket error #10060". Or "Error connecting with SSL. EOF was observed that violates the protocol". What I'm doing wrong? function SendRequest(parameters: string): IXMLDocument; var sPostData: TStringList; sHttpSocket: TIdHTTP; sshSocketHandler: TIdSSLIOHandlerSocketOpenSSL; resStream: TStringStream; xDoc: IXMLDocument; begin sPostData := TStringList.Create; try sPostData.Add('add some parameter to post' + '&'); sPostData.Add('add some parameter to post' + '&'); sPostData.Add('add some parameter to post' + '&'); sPostData.Add(parameters); sHttpSocket := TIdHTTP.Create; sshSocketHandler := TIdSSLIOHandlerSocketOpenSSL.Create; sHttpSocket.IOHandler := sshSocketHandler; sHttpSocket.Request.ContentType := 'application/x-www-form-urlencoded'; sHttpSocket.Request.Method := 'POST'; resStream := TStringStream.Create; sHttpSocket.Post(Self.sUrl, sPostData, resStream); xDoc := CreateXMLDoc; xDoc.LoadFromStream(resStream); Result := xDoc; resStream.Free; sHttpSocket.Free; sshSocketHandler.Free; sPostData.Free; except on E: Exception do begin TCommon.ErrorLog('errorLog.txt', DateTimeToStr(Now) + ' ' + E.Message); end end; end; Maybe I can do this in another way, that works like 100%, when internet connection is available?

  • Calling web service from seems to hang

    - by anothershrubery
    I am trying to call an asmx web service from an Android app. Just literally started some Android development today. I've been following various solutions I have found on the net and on here and it seems it is more difficult than anticipated. I have tried various solutions and using KSoap2 seems to be the easiest way to implement this, well it would be if I could get it working. I have the following code which works up until a point: private class CallWebService extends AsyncTask<Void, Void, Void> { private static final String SOAP_ACTION = "http://tempuri.org/GetUser"; private static final String METHOD_NAME = "GetUser"; private static final String NAMESPACE = "http://tempuri.org/"; private static final String URL = "http://160.10.1.79:59315/Service1.asmx"; TextView tv; @Override protected Void doInBackground(Void... params) { tv=(TextView)findViewById(R.id.txtMessage); try { SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.dotNet=true; envelope.setOutputSoapObject(request); HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); androidHttpTransport.call(SOAP_ACTION, envelope); Object result = (Object)envelope.getResponse(); tv.setText(result.toString()); } catch (Exception e) { tv.setText(e.getMessage()); } return null; } } It seems to hang at the line androidHttpTransport.call(SOAP_ACTION, envelope); Any ideas why? Is this the correct approach? Should I be looking in another direction?

  • Need Help with .NET OpenId HttpHandler

    - by Mark E
    I'm trying to use a single HTTPHandler to authenticate a user's open id and receive a claimresponse. The initial authentication works, but the claimresponse does not. The error I receive is "This webpage has a redirect loop." What am I doing wrong? public class OpenIdLogin : IHttpHandler { private HttpContext _context = null; public void ProcessRequest(HttpContext context) { _context = context; var openid = new OpenIdRelyingParty(); var response = openid.GetResponse(); if (response == null) { // Stage 2: user submitting Identifier openid.CreateRequest(context.Request.Form["openid_identifier"]).RedirectToProvider(); } else { // Stage 3: OpenID Provider sending assertion response switch (response.Status) { case AuthenticationStatus.Authenticated: //FormsAuthentication.RedirectFromLoginPage(response.ClaimedIdentifier, false); string identifier = response.ClaimedIdentifier; //****** TODO only proceed if we don't have the user's extended info in the database ************** ClaimsResponse claim = response.GetExtension<ClaimsResponse>(); if (claim == null) { //IAuthenticationRequest req = openid.CreateRequest(identifier); IAuthenticationRequest req = openid.CreateRequest(Identifier.Parse(identifier)); var fields = new ClaimsRequest(); fields.Email = DemandLevel.Request; req.AddExtension(fields); req.RedirectingResponse.Send(); //Is this correct? } else { context.Response.ContentType = "text/plain"; context.Response.Write(claim.Email); //claim.FullName; } break; case AuthenticationStatus.Canceled: //TODO break; case AuthenticationStatus.Failed: //TODO break; } } }

  • XMLHttpRequest POST Data Size

    - by usurper
    Hi, Is there a size limit to a XHR POST request? I am using the POST method for saving textdata into MySQL using PHP script and the data is cut off. Firebug sends me the following message: ... Firebug request size limit has been reached by Firebug. ... This is my code for sending the data: function makeXHR(recordData) { xmlhttp = createXHR(); var body = "q=" + encodeURIComponent(recordData); xmlhttp.open("POST", "insertRowData.php", true); xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.setRequestHeader("Content-length", body.length); xmlhttp.setRequestHeader("Connection", "close"); xmlhttp.onreadystatechange = function() { if(xmlhttp.readyState == 4 && xmlhttp.status == 200) { //alert(xmlhttp.responseText); alert("Records were saved successfully!"); } } xmlhttp.send(body); } The only solution I can think of is splitting the data and making a queue of XHR requests but I don't like it. Is there another way?

  • How can I prevent double file uploading with Amazon S3?

    - by Tony
    I decided to use Amazon S3 for document storage for an app I am creating. One issue I run into is while I need to upload the files to S3, I need to create a document object in my app so my users can perform CRUD actions. One solution is to allow for a double upload. A user uploads a document to the server my Rails app lives on. I validate and create the object, then pass it on to S3. One issue with this is progress indicators become more complicated. Using most out-of-the-box plugins would show the client that file has finished uploading because it is on my server, but then there would be a decent delay when the file was going from my server to S3. This also introduces unnecessary bandwidth (at least it does not seem necessary) The other solution I am thinking about is to upload the file directly to S3 with one AJAX request, and when that is successful, make a second AJAX request to store the object in my database. One issue here is that I would have to validate the file after it is uploaded which means I have to run some clean up code in S3 if the validation fails. Both seem equally messy. Does anyone have something more elegant working that they would not mind sharing? I would imagine this is a common situation with "cloud storage" being quite popular today. Maybe I am looking at this wrong.

  • Strange behavior with ajax call complete in JavaScript modules

    - by user2598794
    I have 3 simple modules with JavaScript code and JQuery ajax call. First module lots.js: var Lots = (function ($) { var self = this; var processIsRunning; return { getLots: function (lotsUrl) { var items = []; self.processIsRunning = true; var request = $.ajax({ url: lotsUrl, type: 'POST', success: function (data) { //some code } }); $.when(request).done(function() { //some code self.processIsRunning = false; }); }, isComplete: function () { return !self.processIsRunning; } }; }(jQuery)); Module bids.js: var Bids = (function ($) { return { makeBids: function (bidUrl) { //some code } }; }(jQuery)); Module app.js which bundles all together: var App = (function () { var lots_url = null; var bid_url = null; var self = this; return { if (!self.lots_url) { self.lots_url = lotsUrl; } GetLots: function (lotsUrl) { Lots.getLots(self.lots_url); }, MakeBids: function makeBid(bidUrl) { //some code var isComp = Lots.isComplete(); while (!isComp) { isComp = Lots.isComplete(); } Bids.makeBids(self.bid_url); } }; }()); But in the 'while' loop I always get 'isComplete=false'. In debug I see that 'processIsRunning' in Lots module is always true. What's the problem?

  • Java: Tracking a user login session - Session EJBs vs HTTPSession

    - by bguiz
    If I want to keep track of a conversational state with each client using my web application, which is the better alternative - a Session Bean or a HTTP Session - to use? Using HTTP Session: //request is a variable of the class javax.servlet.http.HttpServletRequest //UserState is a POJO HttpSession session = request.getSession(true); UserState state = (UserState)(session.getAttribute("UserState")); if (state == null) { //create default value .. } String uid = state.getUID(); //now do things with the user id Using Session EJB: In the implementation of ServletContextListener registered as a Web Application Listener in WEB-INF/web.xml: //UserState NOT a POJO this this time, it is //the interface of the UserStateBean Stateful Session EJB @EJB private UserState userStateBean; public void contextInitialized(ServletContextEvent sce) { ServletContext servletContext = sce.getServletContext(); servletContext.setAttribute("UserState", userStateBean); ... In a JSP: public void jspInit() { UserState state = (UserState)(getServletContext().getAttribute("UserState")); ... } Elsewhere in the body of the same JSP: String uid = state.getUID(); //now do things with the user id It seems to me that the they are almost the same, with the main difference being that the UserState instance is being transported in the HttpRequest.HttpSession in the former, and in a ServletContext in the case of the latter. Which of the two methods is more robust, and why?

  • SQL Server job (stored proc) trace

    - by Jit
    Hi Friends, I need your suggestion on tracing the issue. We are running data load jobs at early morning and loading the data from Excel file into SQL Server 2005 db. When job runs on production server, many times it takes 2 to 3 hours to complete the tasks. We could drill down to one job step which is taking 99% of the total time to finish. While running the job step (stored procs) on staging environment (with the same production database restored) takes 9 to 10 minutes, the same takes hours on production server when it run at early morning as part of job. The production server always stuck up at the very job step. I would like to run trace on the very job step (around 10 stored procs run for each user in while loop within the job step) and collect the info to figure out the issue. What are the ways available in SQL Server 2005 to achieve the same? I want to run the trace only for these SPs and not for certain period time period on production server, as trace give lots of information and it becomes very difficult for me (as not being DBA) to analyze that much of trace information and figure out the issue. So I want to collect info about specific SPs only. Let me know what you suggest. Appreciate your time and help. Thanks.

  • How to cache code in PHP?

    - by Janis Peisenieks
    I am creating a custom form building system, which includes various tokens. These tokens are found using Regular Expressions, and depending on the type of toke, parsed. Some require simple replacement, some require cycles, and so forth. Now I know, that RegExp is quite resource and time consuming, so I would like to be able to parse the code for the form once, creating a php code, and then save the PHP code, for next uses. How would I go about doing this? So far I have only seen output caching. Is there a way to cache commands like echo and cycles like foreach()? Because of misunderstandings, I'll create an example. Unparsed template data: Thank You for Your interest, [*Title*] [*Firstname*] [*Lastname*]. Here are the details of Your order! [*KeyValuePairs*] Here is the link to Your request: [*LinkToRequest*]. Parsed template: "Thank You for Your interest, <?php echo $data->title;?> <?php echo $data->firstname;?> <?php echo $data->lastname;?>. Here are the details of Your order! <?php foreach($data->values as $key=>$value){ echo $key."-".$value }?> Here is the link to Your request: <?php echo $data->linkToRequest;?>. I would then save the parsed template, and instead of parsing the template every time, just pass the $data variable to the already parsed one, which would generate an output.

  • Django - partially validating form

    - by aeter
    I'm new to Django, trying to process some forms. I have this form for entering information (creating a new ad) in one template: class Ad(models.Model): ... category = models.CharField("Category",max_length=30, choices=CATEGORIES) sub_category = models.CharField("Subcategory",max_length=4, choices=SUBCATEGORIES) location = models.CharField("Location",max_length=30, blank=True) title = models.CharField("Title",max_length=50) ... I validate it with "is_valid()" just fine. Basically for the second validation (another template) I want to validate only against "category" and "sub_category": In another template, I want to use 2 fields from the same form ("category" and "sub_category") for filtering information - and now the "is_valid()" method would not work correctly, cause it validates the entire form, and I need to validate only 2 fields. I have tried with the following: ... if request.method == 'POST': # If a filter for data has been submitted: form = AdForm(request.POST) try: form = form.clean() category = form.category sub_category = form.sub_category latest_ads_list = Ad.objects.filter(category=category) except ValidationError: latest_ads_list = Ad.objects.all().order_by('pub_date') else: latest_ads_list = Ad.objects.all().order_by('pub_date') form = AdForm() ... but it doesn't work. How can I validate only the 2 fields category and sub_category?

  • .NET HttpModule does not send form variables to PHP file on RewritePath()

    - by jammus
    Hello friends. We have an application running on IIS 6 which uses a custom HttpModule to rewrite urls. This works great (well done us) except in the case where the Context.RewritePath destination is a .php file. The php file is executed as expected, however the $_POST collection is empty meaning it cannot access any forms which are submitted to rewritten urls. The problem does not exist when rewriting to .aspx files as the Request.Form collection is fine. My question therefore has two parts: Why is the $_POST collection not being populated? Is there a way to ensure that the .php $_POST collection is correctly populated after a rewrite? I don't have much to show in the way of code. There's just a simple: context.RewritePath(newPath); once the HttpModule has figured out where to send the request. Edit: Interestingly, if I do var_dump(file_get_contents('php://input')); in the PHP file (method described here) the contents of the form is displayed. So the data is reaching the PHP script but not the $_POST array.

  • How would a user stay logged in to a REST-based website?

    - by unforgiven3
    A year or so ago I asked this question: Can you help me understand this? “Common REST Mistakes: Sessions are irrelevant”. My question was essentially this: Okay, I get that HTTP authentication is done automatically on every message - but how? Is the username/password sent with every request? Doesn't that just increase attack surface area? I feel like I'm missing part of the puzzle. The answers I received made perfect sense in the context of a mobile (iPhone, Android, WP7) app - when talking to a REST service, the app would just send user credentials along with each request. That worked great for me. But now, I would like to better understand how one would secure a REST-like website, like StackOverflow itself or something like Reddit. How would things work if it was a user logged in via a web browser instead of logged in via an iPhone app? What happens when a user logs in? Are the credentials saved in the browser somehow? How would the browser know what credentials to send with subsequent REST requests? What if it's a JavaScript call to a webservice? How would the JavaScript call include user credentials? I'll be quite frank: my understanding of security when it comes to websites is pretty limited. I enjoyed working with REST services from an app perspective, but now I want to try and build a website that is based on REST principles, and I'm finding myself to be pretty lost. If there is anything in the above question that is unclear that you'd like me to clarify, please leave a comment and I'll address it.

  • Displaying performance metrics in a modern web app?

    - by Charles
    We're updating our ancient internal PHP application at work. Right now, we gather extensive performance measurements on every pageview, and log them to the database. Additionally, users requested that some of the metrics be displayed at the bottom of the page. This worked out pretty well for us, because the last thing that the application does on every request is include the file containing the HTML footer. The updated parts of the application use an MVC framework and a Dispatch/Request/Response loop. The page footer is no longer the last thing done. In fact, it could very well be the first thing done, before the rest of the page is created. Because we can grab the Response before it's returned to the user, we could try to include placeholders for the performance metrics in the footer and simply replace them with the actual numbers, but this strikes me as a bad idea somehow. How do you handle this in your modern web app? While we're using PHP, I'm curious how it's done in a Ruby/Rails app, and in your favorite Python framework.
