  • problem writing xml to file with .net mvc - timeout?

    - by Mark
    Hey, so having an issue with writing out to an xml file. Works fine for single requests via the browser, but when I use something like Charles to perform 5-10 repeated requests concurrently several of them will fail. The trace simply shows a 500 error with no content inside, basically I think they start timing out waiting for write access or something... This method is inside my repository class, have also attempted to have repository instance as a singleton but doesn't appear to make any difference.. Any help would be much appreciated. Cheers public void Add(Request request) { try { XDocument requests; XmlReader xmlReader; using (xmlReader = XmlReader.Create(_requestsFilePath)) { requests = XDocument.Load(xmlReader); XElement xmlRequest = new XElement("request", new XElement("code", request.code), new XElement("date", request.date), new XElement("email", new XCData(request.email)), new XElement("name", new XCData(request.name)), new XElement("recieveOffers", request.recieveOffers) ); requests.Root.Element("requests").Add(xmlRequest); xmlReader.Close(); } requests.Save(_requestsFilePath); } catch (Exception ex) { HttpContext.Current.Trace.Warn("Error writing to file: "+ex); } }

  • Ruby 1.9 GarbageCollector, GC.disable/enable

    - by seb
    I'm developing a Rails 2.3, Ruby 1.9.1 webapplication that does quite a bunch of calculation before each request. For every request it has to calculate a graph with 300 nodes and ~1000 edges. The graph and all its nodes, edges and other objects are initialized for every request (~2000 objects) - actually they are cloned from an uncalculated cached graph using Marshal.load(Marshal.dump()). Performance is quite an issue here. Right now the whole request takes in average 150ms. I then saw that during a request, parts of the calculation randomly take longer. Assuming, that this might be the GarbageCollector kicking in, I wrapped the request in GC.disable and GC.enable, so that the request waits with garbagecollecting until calculating and rendering have finished. def query GC.disable calculate respond_to do |format| format.html {render} end GC.enable end The average request now takes about 100ms (50 ms less). But I'm unsure if this is a good/stable solution, I assume there must be drawbacks doing that. Does anybody has experience with a similar problem or sees problems with the above code?

  • Client Web Browser Behavior When Handling 301 Redirect

    - by Jon Swanson
    The RFC seems to suggest that the client should permanently cache the response: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html 10.3.2 301 Moved Permanently The requested resource has been assigned a new permanent URI and any future references to this resource SHOULD use one of the returned URIs. Clients with link editing capabilities ought to automatically re-link references to the Request-URI to one or more of the new references returned by the server, where possible. This response is cacheable unless indicated otherwise. The new permanent URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s). If the 301 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued. Note: When automatically redirecting a POST request after receiving a 301 status code, some existing HTTP/1.0 user agents will erroneously change it into a GET request. I'm having a hard time finding concrete browser documentation for any major browser that states how they handle these. I've started digging through the source code of firefox, but quickly got lost. Is the following scenario true for which (if any) browsers, and is there definitive documentation for either Firefox or IE that states as much?: First Time Around: 1.1: User enters link to site A, or clicks on a link directed at Site A 1.2: Browser interprets link at Site A, first time, no cache. Sends GET to Site A. 1.2: Site A responds with 301 Redirect to Site B 1.3: Browser sends GET to Site B. Any Subsequent Times Around: 2.2: User clicks on a link directed at Site A 2.2: Browser sees that, due to a past 301 redirect, Site A should now be Site B. 2.3: Without initiating any request whatsoever at Site A, browser initiates GET at Site B.

  • Rack::ResponseHeaders in rackup for Sinatra

    - by sevennineteen
    I think this is a very easy one, but I can't seem to get it right. Basically, I'm trying to use Rack middleware to set a default Cache-Control header into all responses served by my Sinatra app. It looks like Rack::ResponseHeaders should be able to do exactly what I need, but I get an error when attempting to use the syntax demonstrated here in my rackup file: use Rack::ResponseHeaders do |headers| headers['X-Foo'] = 'bar' headers.delete('X-Baz') end I was able to get Rack::Cache to work successfully as follows: use Rack::Cache, :default_ttl => 3600 However, this doesn't achieve exactly the output I want, whereas Rack::ResponseHeaders gives fine-grained control of the headers. FYI, my site is hosted on Heroku, and the required Rack gems are specified in my .gems manifest. Thanks! Update: After doing some research, it looks like the first issue is that Rack::ResponseHeaders is not found in the version of rack-contrib (0.9.2) which was installed. I'll start by looking into that.

  • X-Forwarded-For causing Undefined index in PHP

    - by bateman_ap
    Hi, I am trying to integrate some third party tracking code into one of my sites, however it is throwing up some errors, and their support isn't being much use, so i want to try and fix their code myself. Most I have fixed, however this function is giving me problems: private function getXForwardedFor() { $s =& $this; $xff_ips = array(); $headers = $s->getHTTPHeaders(); if ($headers['X-Forwarded-For']) { $xff_ips[] = $headers['X-Forwarded-For']; } if ($_SERVER['REMOTE_ADDR']) { $xff_ips[] = $_SERVER['REMOTE_ADDR']; } return implode(', ', $xff_ips); // will return blank if not on a web server } In my dev enviroment where I am showing all errors I am getting: Notice: Undefined index: X-Forwarded-For in /sites/webs/includes/OmnitureMeasurement.class.php on line 1129 Line 1129 is: if ($headers['X-Forwarded-For']) { If I print out $headers I get: Array ( [Host] => www.domain.com [User-Agent] => Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 [Accept] => text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 [Accept-Language] => en-gb,en;q=0.5 [Accept-Encoding] => gzip,deflate [Accept-Charset] => ISO-8859-1,utf-8;q=0.7,*;q=0.7 [Keep-Alive] => 115 [Connection] => keep-alive [Referer] => http://www10.toptable.com/ [Cookie] => PHPSESSID=nh9jd1ianmr4jon2rr7lo0g553; __utmb=134653559.30.10.1275901644; __utmc=134653559 [Cache-Control] => max-age=0 ) I can't see X-Forwarded-For in there which I think is causing the problem.

  • Cache AJAX requests

    - by Willem
    I am sending AJAX GET-requests to a PHP application and would like to cache the request returns for later use. Since I am using GET this should be possible because different requests request different URLs (e.g. getHTML.php?page=2 and getHTML.php?page=5). What headers do I need to declare in the PHP-application to make the clients browser cache the request URL content in a proper way? Do I need to declare anything in the Javascript which handles the AJAX-request (I am using jQuery's $.ajax function which has a cache parameter)? How would I handle edits which change the content of e.g. getHTML.php?page=2 so that the client doesn't fall back to the cached version? Adding another parameter to the GET request e.g. getHTML.php?page=2&version=2 is not possible because the link to the requested URL is created automatically without any checking (which is preferably the way I want it to be). How will the browser react when I try to AJAX-request a cached request URL? Will the AJAX-request return success immediately? Thanks Willem

  • Most elegant way to break CSV columns into separate data structures using Python?

    - by Nick L
    I'm trying to pick up Python. As part of the learning process I'm porting a project I wrote in Java to Python. I'm at a section now where I have a list of CSV headers of the form: headers = [a, b, c, d, e, .....] and separate lists of groups that these headers should be broken up into, e.g.: headers_for_list_a = [b, c, e, ...] headers_for_list_b = [a, d, k, ...] . . . I want to take the CSV data and turn it into dict's based on these groups, e.g.: list_a = [ {b:val_1b, c:val_1c, e:val_1e, ... }, {b:val_2b, c:val_2c, e:val_2e, ... }, {b:val_3b, c:val_3c, e:val_3e, ... }, . . . ] where for example, val_1b is the first row of the 'b' column, val_3c is the third row of the 'c' column, etc. My first "Java instinct" is to do something like: for row in data: for col_num, val in enumerate(row): col_name = headers[col_num] if col_name in group_a: dict_a[col_name] = val elif headers[col_cum] in group_b: dict_b[col_name] = val ... list_a.append(dict_a) list_b.append(dict_b) ... However, this method seems inefficient/unwieldy and doesn't posses the elegance that Python programmers are constantly talking about. Is there a more "Zen-like" way I should try- keeping with the philosophy of Python?

  • Multithreading A Function in VB.Net

  • Connection timed out on Node.js app running under CentOS

    - by ss1271
    I followed this tutorial to create a simple node.js app on my CentOS: the node.js version is: $ node -v v0.10.28 Here's my app.js: // Include http module, var http = require("http"), // And url module, which is very helpful in parsing request parameters. url = require("url"); // show message at console console.log('Node.js app is running.'); // Create the server. http.createServer(function (request, response) { request.resume(); // Attach listener on end event. request.on("end", function () { // Parse the request for arguments and store them in _get variable. // This function parses the url from request and returns object representation. var _get = url.parse(request.url, true).query; // Write headers to the response. response.writeHead(200, { 'Content-Type': 'text/plain' }); // Send data and end response. response.end('Here is your data: ' + _get['data']); }); // Listen on the 8080 port. }).listen(8080); However, when I uploaded this app onto my remote server (assume the address is 123.456.78.9), I couldn't get access to it on my browser http://123.456.78.9:8080/?data=123 The browser returned Error code: ERR_CONNECTION_TIMED_OUT. I tried the same app.js code which runs fine on my local machine, is there anything I am missing? I tried to ping the server and its address was reachable. Thanks.

  • How to access the members of this data in PHP?

The variable contains these contents: (extracted by using var_export()) array ( 'headers' => array ( 'content-type' => 'multipart/alternative; boundary="_689e1a7d-7a0a-442a-bd6c-a1fb1dc2993e_"', ), 'ctype_parameters' => array ( 'boundary' => '_689e1a7d-7a0a-442a-bd6c-a1fb1dc2993e_', ), 'parts' => array ( 0 => stdClass::__set_state(array( 'headers' => array ( 'content-type' => 'text/plain; charset="iso-8859-1"', 'content-transfer-encoding' => 'quoted-printable', ), 'ctype_primary' => 'text', )), ), ) I removed some non-essential data. I want to access the headers value (on the second line above) - simple: $data->headers I want to access the headers value (on the fourteenth line after the stdClass:: stuff) - how?

  • Django ManyToMany Membership errors making associations

  • Generating authentication header from azure table through objective-c

    - by user923370
    I'm fetching data from iCloud and for that I need to generate a header (azure table storage). I used the code below for that and it is generating the headers. But when I use these headers in my project it is showing "make sure that the value of authorization header is formed correctly including the signature." I googled a lot and tried many codes but in vain.

    I've been trying to upload a file (login.zip) using the ASIHTTPRequest libraries from the IPhone onto the inbuilt Apache Server in Mac OS X Snow Leopard. My code is: NSString *urlAddress = [[[NSString alloc] initWithString:self.uploadField.text]autorelease]; NSURL *url = [NSURL URLWithString:urlAddress]; ASIFormDataRequest *request; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"login.zip"]; NSData *data = [[[NSData alloc] initWithContentsOfFile:dataPath] autorelease]; request = [[[ASIFormDataRequest alloc] initWithURL:url] autorelease]; [request setPostValue:@"login.zip" forKey:@"file"]; [request setData:data forKey:@"file"]; [request setUploadProgressDelegate:uploadProgress]; [request setShowAccurateProgress:YES]; [request setDelegate:self]; [request startAsynchronous]; The php code is : <?php $target = "upload/"; $target = $target . basename( $_FILES['uploaded']['name']) ; $ok=1; if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) { echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded"; } else { echo "Sorry, there was a problem uploading your file."; } ?> I don't quite understand why the file is not uploading. If anyone could help me. I've stuck on this for 5 days straight. Thanks in advance Nik

  • HELP Retrieving the url parameter from a JSON store from a EXTJS ComboBox

    - by Newbie
    I am having a problem retrieving the parameters from the url section of a json store for a combobox in EXTJS from my code behind page in c#. The following is the code in the store: var ColorStore = new Ext.data.JsonStore( { autoLoad: true, url: '/proxies/ReturnJSON.aspx?view=rm_colour_view', root: 'Rows', fields: ['company', 'raw_mat_col_code', 'raw_mat_col_desc'] }); And the following code is in my code behind page: protected void Page_Load(object sender, EventArgs e) { string jSonString = ""; connectionClass.connClass func = new connectionClass.connClass(); DataTable dt = func.getDataTable("sELECT * from rm_colour_view"); //Response.Write(Request.QueryString["view"]); string w = Request.Params.Get("url"); string z = Request.Params.Get("view"); string x = Request.Params.Get("view="); string c = Request.Params.Get("?view"); string s = Request.QueryString.Get("view"); string d = Request.Params["?view="]; string f = Request.Form["ColorStore"]; jSonString = Serialize(dt); Response.Write(jSonString); } The string w has gives the following output: /proxies/ReturnJSON.aspx but all the others strings return null... How can rm_colour_view from the datastore then be retrived??? Any help would be appreciated! Thanks

  • Why PHP Error: Call to a member function set_prefix() on a non-object

  • Redirect To Another Site With Header Information Attached Javascript

    - by Nick LaMarca
    I am trying to make a client side click and redirect to another site with header information added, my client side code for the onclick is this: function selectApp(appGUID, userId ,embedUrl) { if(embedUrl==="") { var success = setAppGUID(appGUID); window.location.replace('AppDetail.aspx'); } else { $.ajax({ type: "POST", url: embedUrl, contentType: "text/html", beforeSend: function (xhr, settings) { xhr.setRequestHeader("UserId", userId); }, success: function (msg) { //go to slx window.location.replace(embedUrl); } }); } } And the server side code in "embedUrl" is protected void Page_Load(object sender, EventArgs e) { string isSet = (String)HttpContext.Current.Session["saveUserID"]; if (String.IsNullOrEmpty(isSet)) { NameValueCollection headers = base.Request.Headers; for (int i = 0; i < headers.Count; i++) { if (headers.GetKey(i).Equals("UserId")) { HttpContext.Current.Session["saveUserID"] = headers.Get(i); } } } else { TextBox1.Text = HttpContext.Current.Session["saveUserID"].ToString(); } } This seems to work but its not too elegant. Is there a way to redirect with header data? Without (what Im doing) Saving header info in a session var then doing a redirect in 2 seperate pieces.

  • Does anyone know of any good tutorials for using the APIs from Amazon WeB Services, namely CloudWatc

    - by undefined
    Hi, I have been wrestling with Amazon's CloudWatch API with limited success. Does anyone know of any good resources (other than amazon's api docs) for using the APIs. I have tried to run them using the PHP library for CloudWatch but get nothing but error codes. I am configuring the GetMetricStatisticsSample.php file as follows: $request = array(); $endTime = date("Y-m-d G:i:s"); $yesterday = mktime (date("H"), date("i"), date("s"), date("m"), date("d")-1, date("Y")); $startTime = date("Y-m-d 00:00:00", $yesterday); $request["Statistics.member.1"] = "Average"; $request["EndTime"] = $endTime; $request["StartTime"] = $startTime; $request["MeasureName"] = "CPUUtilization"; $request["Unit"] = "Percent"; invokeGetMetricStatistics($service, $request); But this returns "Caught Exception: Internal Error Response Status Code: 400 Error Code: Error Type: Request ID: XML:" I have also tried from command line as follows - set JAVA_HOME=C:\Program Files\Java\jre1.6.0_05 set AWS_CLOUDWATCH_HOME=C:\AmazonWebServices\API_tools\CloudWatch-1.0.0.24 set PATH=%AWS_CLOUDWATCH_HOME%\bin mon-list-metrics but get C:|Program' is not recognized as an internal or external command... any suggestions? cheers
