  • Tactics for using PHP in a high-load site

    - by Ross
    Before you answer this I have never developed anything popular enough to attain high server loads. Treat me as (sigh) an alien that has just landed on the planet, albeit one that knows PHP and a few optimisation techniques. I'm developing a tool in PHP that could attain quite a lot of users, if it works out right. However while I'm fully capable of developing the program I'm pretty much clueless when it comes to making something that can deal with huge traffic. So here's a few questions on it (feel free to turn this question into a resource thread as well). Databases At the moment I plan to use the MySQLi features in PHP5. However how should I setup the databases in relation to users and content? Do I actually need multiple databases? At the moment everything's jumbled into one database - although I've been considering spreading user data to one, actual content to another and finally core site content (template masters etc.) to another. My reasoning behind this is that sending queries to different databases will ease up the load on them as one database = 3 load sources. Also would this still be effective if they were all on the same server? Caching I have a template system that is used to build the pages and swap out variables. Master templates are stored in the database and each time a template is called it's cached copy (a html document) is called. At the moment I have two types of variable in these templates - a static var and a dynamic var. Static vars are usually things like page names, the name of the site - things that don't change often; dynamic vars are things that change on each page load. My question on this: Say I have comments on different articles. Which is a better solution: store the simple comment template and render comments (from a DB call) each time the page is loaded or store a cached copy of the comments page as a html page - each time a comment is added/edited/deleted the page is recached. Finally Does anyone have any tips/pointers for running a high load site on PHP. I'm pretty sure it's a workable language to use - Facebook and Yahoo! give it great precedence - but are there any experiences I should watch out for? Thanks, Ross

  • Kohana multi language website

    - by Sobek
    .I'm trying to set up a multi language website with kohana v3, following this tutorial: http://kerkness.ca/wiki/doku.php?id=example_of_a_multi-language_website Routing to a controller or action within i.e. website/controller/action seems to work as the url is properly redirected to website/lang/controller/action. However this is not working for ajax request calls. I have to manually edit the url with the appropriate language, to successfully retrieve the data. This also applies for anchors on the html page. In addition to this problem, the overflow parameter 'id' also doesn't work. It takes the 'lang' variable as its parameter. I have setup my default route just like in the tutorial i.e.: Route::set('default', '((<lang>)(/)(<controller>)(/<action>(/<id>)))', array('lang' => "({$langs_abr})",'id'=>'.+')) ->defaults(array('lang' => $default_lang,'controller' => welcome', 'action' => 'index')); Any help is much appreciated ! Cheers

  • Why does the proxy generated code create the wrong class namespace when a MessageContract is in my W

    - by DaleyKD
    I have created two WCF Services (Shipping & PDFGenerator). They both, along with my ClientApp, share an assembly named Kyle.Common.Contracts. Within this assembly, I have three classes: namespace Kyle.Common.Contracts { [MessageContract] public class PDFResponse { [MessageHeader] public string fileName { get; set; } [MessageBodyMember] public System.IO.Stream fileStream { get; set; } } [MessageContract] public class PDFRequest { [MessageHeader] public Enums.PDFDocumentNameEnum docType { get; set; } [MessageHeader] public int? pk { get; set; } [MessageHeader] public string[] emailAddress { get; set; } [MessageBodyMember] public Kyle.Common.Contracts.TrackItResult[] trackItResults { get; set; } } [DataContract(Name = "TrackResult", Namespace = "http://kyle")] public class TrackResult { [DataMember] public int SeqNum { get; set; } [DataMember] public int ShipmentID { get; set; } [DataMember] public string StoreNum { get; set; } } } My PDFGenerator ServiceContract looks like: namespace Kyle.WCF.PDFDocs { [ServiceContract(Namespace="http://kyle")] public interface IPDFDocsService { [OperationContract] PDFResponse GeneratePDF(PDFRequest request); [OperationContract] void GeneratePDFAsync(Kyle.Common.Contracts.Enums.PDFDocumentNameEnum docType, int? pk, string[] emailAddress); [OperationContract] Kyle.Common.Contracts.TrackResult[] Test(); } } If I comment out the GeneratePDF stub, the proxy generated by VS2010 realizes that Test returns an array of Kyle.Common.Contracts.TrackResult. However, if I leave GeneratePDF there, the proxy refuses to use Kyle.Common.Contracts.TrackResult, and instead creates a new class, ClientApp.PDFDocServices.TrackResult, and uses that as the return type of Test. Is there a way to force the proxy generator to use Kyle.Common.Contracts.TrackResult whenever I use a MessageContract? Perhaps there's a better method for using a Stream and File Name as return types? I just don't want to have to create a Copy method to copy from ClientApp.PDFDocServices.TrackResult to Kyle.Common.Contracts.TrackResult, since they should be the exact same class. Thanks in advance, Kyle

  • My SqlComand on SSIS - DataFlow OLE DB Command seems not works

    - by Angel Escobedo
    Hello Im using OLE DB Source for get rows from a dBase IV file and it works, then I split the data and perform a group by with aggregate component. So I obtain a row with two columns with "null" value : CompanyID | CompanyName | SubTotal | Tax | TotalRevenue Null Null 145487 27642.53 173129.53 this success because all rows have been grouped with out taking care about the firsts columns and just Summing the valuable columns, so I need to change that null for default values as CompanyID = "100000000" and CompanyName = "Others". I try use SqlCommand on a OLE DB Command Component : SELECT "10000000" AS RUCCLI , "Otros - Varios" AS RAZCLI FROM RGVCAFAC <property id="1505" name="SqlCommand" dataType="System.String" state="default" isArray="false" description="The SQL command to be executed." typeConverter="" UITypeEditor="Microsoft.DataTransformationServices.Controls.ModalMultilineStringEditor, Microsoft.DataTransformationServices.Controls, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" containsID="false" expressionType="Notify">SELECT "10000000" AS RUCCLI , "Otros - Varios" AS RAZCLI FROM RGVCAFAC</property> but nothings happens, why? and finally the task finish when the data is inserted on a SQL Server Table.

  • Property being immediately reset by ApplicationSetting Property Binding

    - by Slider345
    I have a .net 2.0 windows application written in c#, which currently uses several project settings to store user configurations. The forms in the application are made up of lots of user controls, each of which have properties that need to be set to these project settings. Right now these settings are manually assigned to the user control properties. I was hoping to simplify the code by replacing the manual implementation with ApplicationSettings Property Bindings. However, my first property is not behaving properly at all. The setting is an integer, used to record a port number typed into a text box. The setting is bound to an integer property on a user control, and that property sets the Text property on a TextBox control. When I type a new value into the textbox at runtime, as soon as the textbox loses focus, it is immediately replaced by the original value. A breakpoint on the property shows that it is immediately setting the property to the setting from the properties collection after I set it. Can anyone see what I'm doing wrong? Here's some code: The setting: [global::System.Configuration.UserScopedSettingAttribute()] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.Configuration.DefaultSettingValueAttribute("1000")] public int Port { get{ return ((int)(this["Port"])); } set{ this["Port"] = value; } } The binding: this.ctrlNetworkConfig.DataBindings.Add(new System.Windows.Forms.Binding("PortNumber", global::TestProject.Properties.Settings.Default, "Port", true, System.Windows.Forms.DataSourceUpdateMode.OnPropertyChanged)); this.ctrlNetworkConfig.PortNumber = global::TestProject.Properties.Settings.Default.Port; And lastly, the property on the user control: public int PortNumber { get{ int port; if(int.TryParse(this.txtPortNumber.Text, out port)) return port; else return 0; } set{ txtPortNumber.Text = value.ToString(); } } Any thoughts? Thanks in advance for your help. EDIT: Sorry about the formatting, trying to correct.

  • problem with addressfilter in WCF

    - by Zé Carlos
    I've build my own WCF channel with all necessary stuff (like encoders, bindings, etc) to use it with ServiceHost. I just want to build the "channel stack" making no custumizations at "Service Model". To acomplish this, my encoder returns perfect ServiceModel.Messages with a XML infoset just like other channel does. Lets assume the following service implementation: [ServiceContract(Namespace = "http://MyNS")] public interface IService1 { [OperationContract(IsOneWay = true)] void dummy(); } public class Service1 : IService1 { public void dummy() { Console.WriteLine("In Service1:dummy()"); } } I used this service through other bindings and traced the following ServiceModel.Message contents (SOAP format): <s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing"> <s:Header> <a:Action s:mustUnderstand="1">http://MyNS/IService1/dummy</a:Action> <a:To s:mustUnderstand="1">amqp://localhost</a:To> </s:Header> <s:Body> <dummy xmlns="http://MyNS"></dummy> </s:Body> </s:Envelope> Then (just to debug) i changed my encoder to allways return this message. When i use my custom channel the WCF's runtime replay with an faul message telling: "The message with To '' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree." I read that the default EndPointDispatcher.AddressFilter simply looks to the "TO" header and delivery the message to corresponding service. This is happening with other bindings, why not happens with my custom channel too? Is there any way to i check what default AddressFilter is doing? Thanks

  • Viewing a large-resolution VNC server through a small-resolution viewer in Ubuntu

    - by Madiyaan Damha
    I have two Ubuntu computers, one with a large screen resolution (1920x1600) that is running default ubuntu vnc server. I have another computer that has a resolution of about 1200x1024 that I use to vnc into the server (I use the default ubuntu vnc viewer). Now everything works fine except there are annoying scrollbars in the viewer because the server's desktop resolution is so much higher than the viewer's. Is there a way to: 1) Scale the server's desktop down to the viewer's resolution. I know there will be a loss of image quality, but I am willing to try it out. This should be something like how windows media player or vlc scales down the window (and does some interpolation of pixels). 2) Automatically shrink the resolution of the server to the client's when I connect and scale the resolution back when I disconnect. This seems like a less attractive solution. 3) Any other solution that gurus out there use? I am sure someone has experienced this before (annoying scroll bars) so there must be a solution out there. Thanks,

  • How to avoid using duplicate savepoint names in nested transactions in nested stored procs?

    - by Gary McGill
    I have a pattern that I almost always follow, where if I need to wrap up an operation in a transaction, I do this: BEGIN TRANSACTION SAVE TRANSACTION TX -- Stuff IF @error <> 0 ROLLBACK TRANSACTION TX COMMIT TRANSACTION That's served me well enough in the past, but after years of using this pattern (and copy-pasting the above code), I've suddenly discovered a flaw which comes as a complete shock. Quite often, I'll have a stored procedure calling other stored procedures, all of which use this same pattern. What I've discovered (to my cost) is that because I'm using the same savepoint name everywhere, I can get into a situation where my outer transaction is partially committed - precisely the opposite of the atomicity that I'm trying to achieve. I've put together an example that exhibits the problem. This is a single batch (no nested stored procs), and so it looks a little odd in that you probably wouldn't use the same savepoint name twice in the same batch, but my real-world scenario would be too confusing to post. CREATE TABLE Test (test INTEGER NOT NULL) BEGIN TRAN SAVE TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (1) COMMIT TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (2) COMMIT TRAN TX DELETE FROM Test ROLLBACK TRAN TX COMMIT TRAN TX SELECT * FROM Test DROP TABLE Test When I execute this, it lists one record, with value "1". In other words, even though I rolled back my outer transaction, a record was added to the table. What's happening is that the ROLLBACK TRANSACTION TX at the outer level is rolling back as far as the last SAVE TRANSACTION TX at the inner level. Now that I write this all out, I can see the logic behind it: the server is looking back through the log file, treating it as a linear stream of transactions; it doesn't understand the nesting/hierarchy implied by either the nesting of the transactions (or, in my real-world scenario, by the calls to other stored procedures). So, clearly, I need to start using unique savepoint names instead of blindly using "TX" everywhere. But - and this is where I finally get to the point - is there a way to do this in a copy-pastable way so that I can still use the same code everywhere? Can I auto-generate the savepoint name on the fly somehow? Is there a convention or best-practice for doing this sort of thing? It's not exactly hard to come up with a unique name every time you start a transaction (could base it off the SP name, or somesuch), but I do worry that eventually there would be a conflict - and you wouldn't know about it because rather than causing an error it just silently destroys your data... :-(

  • changing vim's vertsplit character to ¦

    - by ldigas
    This is, I assume, codepage related, but doesn't hurt asking. How would one, on windows xp's cmd, gvim 7.2 change vertsplit character, so that instead of default | it is ¦ (so that it makes a full, and not an splitted line) ? That character is usually changed with set fillchars=vert:\| and I can copy paste the ascii graphics line there, but it comes out as garbage. I suppose I would have to change vim's internal codepage for it to show correctly ? Anyone knows how to do this ?

Perhaps there's a better method for using a Stream and File Name as return types? I just don't want to have to create a Copy method to copy from ClientApp.PDFDocServices.TrackResult to Kyle.Common.Contracts.TrackResult, since they should be the exact same class.

  • Help Converting T-SQL Query to LINQ Query

    - by campbelt
    I am new to LINQ, and so am struggle over some queries that I'm sure are pretty simple. In any case, I have been hiting my head against this for a while, but I'm stumped. Can anyone here help me convert this T-SQL query into a LINQ query? Once I see how it is done, I'm sure I'll have some question about the syntax: SELECT BlogTitle FROM Blogs b JOIN BlogComments bc ON b.BlogID = bc.BlogID WHERE b.Deleted = 0 AND b.Draft = 0 AND b.[Default] = 0 AND bc.Deleted = 0 GROUP BY BlogTitle ORDER BY MAX([bc].[Timestamp]) DESC Just to show that I have tried to solve this on my own, here is what I've come up with so far, though it doesn't compile, let alone work ... var iqueryable = from blog in db.Blogs join blogComment in db.BlogComments on blog.BlogID equals blogComment.BlogID where blog.Deleted == false && blog.Draft == false && blog.Default == false && blogComment.Deleted == false group blogComment by blog.BlogID into blogGroup orderby blogGroup.Max(blogComment => blogComment.Timestamp) select blogGroup;
