  • Accessing Elmah.axd with SqlErrorLog in SharePoint without adding user to db

    - by Chloraphil
    I have installed/configured Elmah on my personal SharePoint dev environment and everything works great since I'm logged in as admin, etc. I am using the MS Sql Server Error Log. (I am also using log4net to handle DEBUG/INFO/etc level logging and log statements are also stored in the db, in the same table as ELMAH's.) However, on the actual dev server (not my personal environment), when I access http://example/elmah.axd I get the error "Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'". I understand that this is the traditional error for the "double-hop problem" but I don't even want my credentials to be passed along - I would just like the database access to be made with the credentials of the Application Pool Identity. When using the SP object model the SPSecurity.RunWithElevatedPrivileges is available; however, I do not want to modify the Elmah source. My production environment precludes the use of SQL Server authentication, changing impersonation to false, or giving myself permissions on the db directly. How can I get this to work? Am I missing something?

  • Setting up an efficient and effective development process

    - by christopher-mccann
    I am in the midst of setting up the development environment (PHP/MySQL) for my start-up. We use three sets of servers: LIVE - the servers which provide the actual application TEST - providing a testing version before it is actually released DEV - the development servers The development servers run SVN with each developer checking out their local copy. At the end of each day completed fixes are checked in and then we use Hudson to automate our build process and then transfer it over to TEST. We then check the application still functions correctly using a tester and then if everything is fine move it to LIVE. I am happy with this process but I do have two questions: How would you recommend we do local testing - as each developer adds new pages or changes functionality I want them to be able to test what they are doing. Would you just setup local Apache and a local database and have them test locally on their own machine? How would you recommend dealing with data layer changes? Is there anything else you would recommend doing to really make our development process as easy and efficient as possible? Thanks in advance

  • how to run pentaho bi-server on CentOS 6.2 and PostgreSQL 8.4.x?

    - by gtludwig
    I'm trying to run an instance of Pentaho's bi-server-ce on a freshly installed CentOS 6.2 using PostgreSQL 8.4.x. I've installed a JDK 1.6 instance and it is working. Also I've a tomcat 6.0.35 instance where I run a few apps. I'd like bi-server to be one of many apps I run on this tomcat. Regarding Pentaho's Bi-Server installation I'm following the guide from https://docs.google.com/document/edit?id=1OnvHYsa-nYgwP8bjqRqjP5Vy-gLI5xomOHZtOvA00Ns#bookmark=id.2d95068df264 I've adapted the steps to my local installation, but still I can't start the server. I get the following error when trying to start the pentaho app: Jul 23, 2012 12:00:30 PM org.apache.catalina.startup.ContextConfig validateSecurityRoles INFO: WARNING: Security role name PENTAHO_ADMIN used in an without being defined in a 12:00:31,953 ERROR [JDBCExceptionReporter] FATAL: Ident authentication failed for user "hibuser" 12:00:32,222 ERROR [JDBCExceptionReporter] FATAL: Ident authentication failed for user "hibuser" 12:00:32,223 ERROR [SchemaUpdate] could not get database metadata org.postgresql.util.PSQLException: FATAL: Ident authentication failed for user "hibuser" (...) I do believe it's something related to the postgre user hibuser, but all settings on all files seem to be OK. Also I've a copy of the postgresql jar driver on tomcat's /lib folder. I've run out of ideas, can anyone throw me light here?

  • [C#] Lock a file and avoid readings while it's writing

    - by vtortola
    Hi, My web application returns a file from the filesystem. These files are dynamic, so I have no way to know the names o how many of them will there be. When this file doesn't exist, the application creates it from the database. I want to avoid that two different threads recreate the same file at the same time, or that a thread try to return the file while other thread is creating it. So I want to lock a file till its recreation is complete, if other thread try to access it ... it will have to wait the file be unlocked. I've been reading about FileStream.Lock, but I have to know the file length and it won't prevent that other thread try to read the file, so it doesn't work for my particular case. I've been reading also about FileAccess.None, but it will throw an exception (which exception type?) if other thread/process try to access the file... so I should develop a "try again while is faulting" ... and I don't like too much that approach, although maybe there is not a better way. How could I archieve this? Kind regards.

  • PHP MySQL Update query

    - by Jordan Pagaduan
    I have a website that has an update query. Example. Table name - myTable Table Content - id(AI) name -- myName age -- 13 image -- (no values) birthdate -- (no values) I only put values in name and age. In image and birthdate, I haven't put anything. If I edit it and update it and I don't put anything in name and in age, I only put values in image and in birthdate. The output is like this. (This ouput I wanted) Table name - myTable Table Content - id(AI) name -- myName age -- 13 image -- myImage.jpg birthdate -- Feb. 31, 2010 This is my code: <?php //mysql connect... //mysql select database... $sql = "UPDATE myTable SET name = '".$name."', age = '".$age."', image = '".$image."', birthdate"'$birthdate.."' WHERE id = $id"; mysql_query($sql); ?> I used this code but the output is: Table name - myTable Table Content - id(AI) name -- (no values) age -- (no values) image -- myImage.jpg birthdate -- Feb. 31, 2010 Feel free to ask if you don't understand my question Thank you

  • Shouldn't prepared statements be much more fsater?

    - by silversky
    $s = explode (" ", microtime()); $s = $s[0]+$s[1]; $con = mysqli_connect ('localhost', 'test', 'pass', 'db') or die('Err'); for ($i=0; $i<1000; $i++) { $stmt = $con -> prepare( " SELECT MAX(id) AS max_id , MIN(id) AS min_id FROM tb "); $stmt -> execute(); $stmt->bind_result($M,$m); $stmt->free_result(); $rand = mt_rand( $m , $M ).'<br/>'; $res = $con -> prepare( " SELECT * FROM tb WHERE id >= ? LIMIT 0,1 "); $res -> bind_param("s", $rand); $res -> execute(); $res->free_result(); } $e = explode (" ", microtime()); $e = $e[0]+$e[1]; echo number_format($e-$s, 4, '.', ''); // and: $link = mysql_connect ("localhost", "test", "pass") or die (); mysql_select_db ("db") or die ("Unable to select database".mysql_error()); for ($i=0; $i<1000; $i++) { $range_result = mysql_query( " SELECT MAX(`id`) AS max_id , MIN(`id`) AS min_id FROM tb "); $range_row = mysql_fetch_object( $range_result ); $random = mt_rand( $range_row->min_id , $range_row->max_id ); $result = mysql_query( " SELECT * FROM tb WHERE id >= $random LIMIT 0,1 "); } defenitly prepared statements are much more safer but also every where it says that they are much faster BUT in my test on the above code I have: - 2.45 sec for prepared statements - 5.05 sec for the secon example What do you think I'm doing wrong? Should I use the second solution or I should try to optimize the prep stmt?

  • Store comparison in variable (or execute comparison when it's given as an string)

    - by BorrajaX
    Hello everyone. I'd like to know if the super-powerful python allows to store a comparison in a variable or, if not, if it's possible calling/executing a comparison when given as an string ("==" or "!=") I want to allow the users of my program the chance of giving a comparison in an string. For instance, let's say I have a list of... "products" and the user wants to select the products whose manufacturer is "foo". He could would input something like: Product.manufacturer == "foo" and if the user wants the products whose manufacturer is not "bar" he would input Product.manufacturer != "bar" If the user inputs that line as an string, I create a tree with an structure like: != / \ manufacturer bar I'd like to allow that comparison to run properly, but I don't know how to make it happen if != is an string. The "manufacturer" field is a property, so I can properly get it from the Product class and store it (as a property) in the leaf, and well... "bar" is just an string. I'd like to know if I can something similar to what I do with "manufacturer": storing it with a 'callable" (kind of) thing: the property with the comparator: != I have tried with "eval" and it may work, but the comparisons are going to be actually used to query a MySQL database (using sqlalchemy) and I'm a bit concerned about the security of that... Any idea will be deeply appreciated. Thank you! PS: The idea of all this is being able to generate a sqlalchemy query, so if the user inputs the string: Product.manufacturer != "foo" || Product.manufacturer != "bar" ... my tree thing can generate the following: sqlalchemy.or_(Product.manufacturer !="foo", Product.manufacturer !="bar") Since sqlalchemy.or_ is callable, I can also store it in one of the leaves... I only see a problem with the "!="

  • ORM Persistence by Reachability violates Aggregate Root Boundaries?

    - by Johannes Rudolph
    Most common ORMs implement persistence by reachability, either as the default object graph change tracking mechanism or an optional. Persistence by reachability means the ORM will check the aggregate roots object graph and determines wether any objects are (also indirectly) reachable that are not stored inside it's identity map (Linq2Sql) or don't have their identity column set (NHibernate). In NHibernate this corresponds to cascade="save-update", for Linq2Sql it is the only supported mechanism. They do both, however only implement it for the "add" side of things, objects removed from the aggregate roots graph must be marked for deletion explicitly. In a DDD context one would use a Repository per Aggregate Root. Objects inside an Aggregate Root may only hold references to other Aggregate Roots. Due to persistence by reachability it is possible this other root will be inserted in the database event though it's corresponding repository wasn't invoked at all! Consider the following two Aggregate Roots: Contract and Order. Request is part of the Contract Aggregate. The object graph looks like Contract->Request->Order. Each time a Contractor makes a request, a corresponding order is created. As this involves two different Aggregate Roots, this operation is encapsulated by a Service. //Unit Of Work begins Request r = ...; Contract c = ContractRepository.FindSingleByKey(1); Order o = OrderForRequest(r); // creates a new order aggregate r.Order = o; // associates the aggregates c.Request.Add(r); ContractRepository.SaveOrUpdate(c); // OrderAggregate is reachable and will be inserted Since this Operation happens in a Service, I could still invoke the OrderRepository manually, however I wouldn't be forced to!. Persistence by reachability is a very useful feature inside Aggregate Roots, however I see no way to enforce my Aggregate Boundaries.

  • Overlay only draws line between first 2 GPS points in Android

    - by LordSnoutimus
    Hi, I am experiencing an unusual error using ItemizedOverlay in Android. I am creating a GPS tracking device that plots a route between waypoints stored in a database. When I provide the first two sets of longitude and latitude points through the emulator in Eclipse, it draws a red line just how I want it, but if I send another GPS point, it animates to the point, but does not draw a line from the last point. public class MyOverlay extends ItemizedOverlay { // private Projection projection; private Paint linePaint; private Vector points; public MyOverlay(Drawable defaultMarker) { super(defaultMarker); points = new Vector<GeoPoint>(); //set colour, stroke width etc. linePaint = new Paint(); linePaint.setARGB(255, 255, 0, 0); linePaint.setStrokeWidth(3); linePaint.setDither(true); linePaint.setStyle(Style.FILL); linePaint.setAntiAlias(true); linePaint.setStrokeJoin(Paint.Join.ROUND); linePaint.setStrokeCap(Paint.Cap.ROUND); } public void addPoint(GeoPoint point) { points.addElement(point); } public void draw(Canvas canvas, MapView view, boolean shadow) { int size = points.size(); Point lastPoint = new Point(); if(size == 0) return; view.getProjection().toPixels(points.get(0), lastPoint); Point point = new Point(); for(int i = 1; i<size; i++){ view.getProjection().toPixels(points.get(i), point); canvas.drawLine(lastPoint.x, lastPoint.y, point.x, point.y, linePaint); lastPoint = point; } } @Override protected OverlayItem createItem(int arg0) { // TODO Auto-generated method stub return null; } @Override public int size() { // TODO Auto-generated method stub return 0; } }

  • Newbie, deciding Python or Erlang

    - by Joe
    Hi Guys, I'm a Administrator (unix, Linux and some windows apps such as Exchange) by experience and have never worked on any programming language besides C# and scripting on Bash and lately on powershell. I'm starting out as a service provider and using multiple network/server monitoring tools based on open source (nagios, opennms etc) in order to monitor them. At this moment, being inspired by a design that I came up with, to do more than what is available with the open source at this time, I would like to start programming and test some of these ideas. The requirement is that a server software that captures a stream of data and store them in a database(CouchDB or MongoDB preferably) and the client side (agent installed on a server) would be sending this stream of data on a schedule of every 10 minutes or so. For these two core ideas, I have been reading about Python and Erlang besides ruby. I do plan to use either Amazon or Rackspace where the server platform would run. This gives me the scalability needed when we have more customers with many servers. For that reason alone, I thought Erlang was a better fit(I could be totally wrong, new to this game) and I understand that Erlang has limited support in some ways compared to Ruby or Python. But also I'm totally new to the programming realm of things and any advise would be appreciated grately. Jo

  • How can i handle a form submit using REAL OOP in PHP

    - by Lorence
    Im used to java and creating UML.. and i was wondering how can PHP be OOP, the objects live only until you make a request.. then they destroy, so if im using a database is useless to create a class and add the members (variables) to the class, they will be useless.. i cant pass the main system object from one page to another, or similar so how can PHP be compare to jave? you never do OOP .. i mean REAL OOP.. not creating classes , in fact your index will be a procedural file with some object instance and then ? how about if i make a html form and i want to submit the data.. i have to call a file which is not a class is a php procedural file were i grab the submited data with POST, from that file you will instance a class and do some logic there.. but for me thats not pure OOP.. can somebody point me to the right way of OOP using a form submit example ? Thanks!

  • Invalid length for a Base-64 char array.

    - by Code Sherpa
    As the title says, I am getting: Invalid length for a Base-64 char array. I have read about this problem on here and it seems that the suggestion is to store ViewState in SQL if it is large. I am using a wizard with a good deal of data collection so chances are my ViewSate is large. But, before I turn to the "store-in-DB" solution, maybe somebody can take a look and tell me if I have other options? I construct the email for delivery using the below method: public void SendEmailAddressVerificationEmail(string userName, string to) { string msg = "Please click on the link below or paste it into a browser to verify your email account.<BR><BR>" + "<a href=\"" + _configuration.RootURL + "Accounts/VerifyEmail.aspx?a=" + userName.Encrypt("verify") + "\">" + _configuration.RootURL + "Accounts/VerifyEmail.aspx?a=" + userName.Encrypt("verify") + "</a>"; SendEmail(to, "", "", "Account created! Email verification required.", msg); } The Encrypt method looks like this: public static string Encrypt(string clearText, string Password) { byte[] clearBytes = System.Text.Encoding.Unicode.GetBytes(clearText); PasswordDeriveBytes pdb = new PasswordDeriveBytes(Password, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 }); byte[] encryptedData = Encrypt(clearBytes, pdb.GetBytes(32), pdb.GetBytes(16)); return Convert.ToBase64String(encryptedData); } On the receiving end, the VerifyEmail.aspx.cs page has the line: string username = Cryptography.Decrypt(_webContext.UserNameToVerify, "verify"); And the decrypt method looks like: public static string Decrypt(string cipherText, string password) { **// THE ERROR IS THROWN HERE!!** byte[] cipherBytes = Convert.FromBase64String(cipherText); Can this error be remedied with a code fix or must I store ViewState in the database? Thanks in advance.

  • Duplicate a collection of entities and persist in Hibernate/JPA

    - by Michael Bavin
    Hi, I want to duplicate a collection of entities in my database. I retreive the collection with: CategoryHistory chNew = new CategoryHistory(); CategoryHistory chLast = (CategoryHistory)em.createQuery("SELECT ch from CategoryHistory ch WHERE ch.date = MAX(date)").getSingleResult; List<Category> categories = chLast.getCategories(); chNew.addCategories(categories)// Should be a copy of the categories: OneToMany Now i want to duplicate a list of 'categories' and persist it with EntityManager. I'm using JPA/Hibernate. UPDATE After knowing how to detach my entities, i need to know what to detach: current code: CategoryHistory chLast = (CategoryHistory)em.createQuery("SELECT ch from CategoryHistory ch WHERE ch.date=(SELECT MAX(date) from CategoryHistory)").getSingleResult(); Set<Category> categories =chLast.getCategories(); //detach org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession(); session.evict(chLast);//detaches also its child-entities? //set the realations chNew.setCategories(categories); for (Category category : categories) { category.setCategoryHistory(chNew); } //set now create date chNew.setDate(Calendar.getInstance().getTime()); //persist em.persist(chNew); This throws a failed to lazily initialize a collection of role: entities.CategoryHistory.categories, no session or session was closed exception. I think he wants to lazy load the categories again, as i have them detached. What should i do now?

  • Complete list of tools and technologies that make up a solid ASP.NET MVC 2 development environment f

    - by Dr Dork
    This question is related to another wiki I found on SO, but I'd like to develop a more comprehensive example of an automated ASP MVC 2 development environment that can be used to develop and deploy a wide range of small-scale websites by beginners. As far as characteristics of the dev environment go, I'd like to focus on beginner-friendly over powerful since the other wiki focuses more on advanced, powerful setups. This information is targeted for beginners (that already know C# and understand web dev concepts) that have selected... ASP.NET MVC 2 as their dev framework Visual Studio 2010 Pro (or 2008 Pro SP1) as their IDE Windows 7 as their OS and are looking for a quick and easy-to-setup environment that covers managing, building, testing, tracking, and deploying their website with as much automation as possible. A system that can be used for becoming familiar with the whole process, as well as a launching point for exploring other, more custom and powerful systems. Since we've already selected the Compiler, Framework, and OS, I'd like to develop ideas for... Code editor (unless you feel VS will suffice for all areas of code) Database and related tools Unit testing (VS?) Continuous integration build system (VS?) Project Planning Issue tracking Deployment (VS?) Source management (VS?) ASP, C#, VS, and related blogs that beginners can follow Any other categories I'm probably missing Since we're already using Visual Studio, I'd like to focus on the out-of-the-box solutions and features built into Visual Studio, unless you feel there are better solutions that work well with VS and are easier to use than the features built directly into VS. Thanks so much in advance for your wisdom!

But no when i want to place some logic for boolean, like this: private System.Nullable<short> _deleted = 1; [Column(Storage = "_deleted", Name = "deleted", DbType = "SmallInt", CanBeNull = true)] public bool deleted { get { if (this._deleted == 1) { return true; } return false; } set { if(value == true) { this._deleted = (short)1; }else { this._deleted = (short)0; } } } I get always runtime error: [TypeLoadException: GenericArguments[2], "System.Nullable`1[System.Int16]", on 'System.Data.Linq.Mapping.PropertyAccessor+Accessor`3[T,V,V2]' violates the constraint of type parameter 'V2'.] I can't change the database to bit.. I need to have casting in mapping class.

  • ASP.NET MVC 2.0 Validation and ErrorMessages

    - by Raj Aththanayake
    I need to set the ErrorMessage property of the DataAnnotation's validation attribute in MVC 2.0. For example I should be able to pass an ID instead of the actual error message for the Model property, for example... [StringLength(2, ErrorMessage = "EmailContentID")] [DataType(DataType.EmailAddress)] public string Email { get; set; } Then use this ID ("EmailContentID") to retrieve some content(error message) from a another service e.g database. Then the error error message is displayed to the user instead of the ID. In order to do this I need to set the DataAnnotation validation attribute’s ErrorMessage property. It seems like a stright forward task by just overriding the DataAnnotationsModelValidatorProvider‘s protected override IEnumerable GetValidators(ModelMetadata metadata, ControllerContext context, IEnumerable attributes) However it is complicated now.... A. MVC DatannotationsModelValidator’s ErrorMessage property is readonly. So I cannot set anything here B. System.ComponentModel.DataAnnotationErrorMessage property(get and set) which is already set in MVC DatannotationsModelValidator so I cannot set it again. If I try to set it I get “The property cannot set more than once…” error message. public class CustomDataAnnotationProvider : DataAnnotationsModelValidatorProvider { protected override IEnumerable<ModelValidator> GetValidators(ModelMetadata metadata, ControllerContext context, IEnumerable<Attribute> attributes) { IEnumerable<ModelValidator> validators = base.GetValidators(metadata, context, attributes); foreach (ValidationAttribute validator in validators.OfType<ValidationAttribute>()) { messageId = validator.ErrorMessage; validator.ErrorMessage = "Error string from DB And" + messageId ; } //...... } } Can anyone please give me the right direction on this? Thanks in advance.

  • Save a PDF created with FPDF php library in a MySQL blob field

    - by Davide Gualano
    I need to create a pdf file with the fpdf library and save it in a blob field in my MySQL database. The problem is, when I try to retrieve the file from the blob field and send it to the browser for the download, the donwloaded file is corrupted and does not display correctly. The same pdf file is correctly displayed if I send it immediately to the browser without storing it in the db, so it seems some of the data gets corrupted when is inserted in the db. My code is something like this: $pdf = new MyPDF(); //class that extends FPDF and create te pdf file $content = $pdf->Output("", "S"); //return the pdf file content as string $sql = "insert into mytable(myblobfield) values('".addslashes($content)."')"; mysql_query($sql); to store the pdf, and like this: $sql = "select myblobfield from mytable where id = '1'"; $result = mysql_query($sql); $rs = mysql_fetch_assoc($result); $content = stripslashes($rs['myblobfield']); header('Content-Type: application/pdf'); header("Content-Length: ".strlen(content)); header('Content-Disposition: attachment; filename=myfile.pdf'); print $content; to send it to the browser for downloading. What am I doing wrong? If I change my code to: $pdf = new MyPDF(); $pdf->Output(); //send the pdf to the browser the file is correctly displayed, so I assume that is correctly generated and the problem is in the storing in the db. Thanks in advance.

  • should I use Entity Framework instead of raw ADO.NET

    - by user110182
    I am new to CSLA and Entity Framework. I am creating a new CSLA / Silverlight application that will replace a 12 year old Win32 C++ system. The old system uses a custom DCOM business object library and uses ODBC to get to SQL Server. The new system will not immediately replace the old system -- they must coexist against the same database for years to come. At first I thought EF was the way to go since it is the latest and greatest. After making a small EF model and only 2 CSLA editable root objects (I will eventually have hundreds of objects as my DB has 800+ tables) I am seriously questioning the use of EF. In the current system I have the need many times to do fine detail performance tuning of the queries which I can do because of 100% control of generated SQL. But it seems in EF that so much happens behind the scenes that I lose that control. Article like http://toomanylayers.blogspot.com/2009/01/entity-framework-and-linq-to-sql.html don't help my impression of EF. People seem to like EF because of LINQ to EF but since my criteria is passed between client and server as criteria object it seems like I could build queries just as easily without LINQ. I understand in WCF RIA that there is query projection (or something like that) where I can do client side LINQ which does move to the server before translation into actual SQL so in that case I can see the benefit of EF, but not in CSLA. If I use raw ADO.NET, will I regret my decision 5 years from now? Has anyone else made this choice recently and which way did you go?

  • Using jquery pagination plugin

    - by eddy
    Hi. I want to use this plugin, but I don't know if it'll meet all of my requirements. I know I have to use JSON to fetch the data from the server and then use it at the client side, is that right?. For now, that's fine, because I only have very few records, but when I have thousands of ; will it be convenient to bring all the data at once? What I would like to know is : Is there any way to query the database every time I press the number of an specific page? I ask this cause I don't think is a good idea to load all the data in one go, is it? I used to pass the id of the record I was going to edit like this : <td align="center"> <c:url value="edititem.htm" var="url"> <c:param name="id" value="${item.id}"/> </c:url> <a href="<c:out value="${url}"/>"><img src="images/edit.png" width="14" height="14" alt="edit"/></a> </td> but now I don't know not how to do it. I really hope you can help me out. Thanks in advance.

  • MySQL performance - 100Mb ethernet vs 1Gb ethernet

    - by Rob Penridge
    Hi All I've just started a new job and noticed that the analysts computers are connected to the network at 100Mbps. The ODBC queries we run against the MySQL server can easily return 500MB+ and it seems at times when the servers are under high load the DBAs kill low priority jobs as they are taking too long to run. My question is this... How much of this server time is spent executing the request, and how much time is spent returning the data to the client? Could the query speeds be improved by upgrading the network connections to 1Gbps? (Updated for the why): The database in question was built to accomodate reporting needs and contains massive amounts of data. We usually work with subsets of this data at a granular level in external applications such as SAS or Excel, hence the reason for the large amounts of data being transmitted. The queries are not poorly structured - they are very simple and the appropriate joins/indexes etc are being used. I've removed 'query' from the Title of the post as I realised this question is more to do with general MySQL performance rather than query related performance. I was kind of hoping that someone with a Gigabit connection may be able to actually quantify some results for me here by running a query that returns a decent amount of data, then they could limit their connection speed to 100Mb and rerun the same query. Hopefully this could be done in an environment where loads are reasonably stable so as not to skew the results. If ethernet speed can improve the situation I wanted some quantifiable results to help argue my case for upgrading the network connections. Thanks Rob

  • Why is Selenium RC so slow?

    - by Pete
    Hi. For some time I have been investigating Selenium RC in order to do functional testing of my web application. I have now found a test strategy that is so effective, that I do not want to move away from Selenium RC (after spending weeks trying to figure out a good way to validate ASP.NET validation controls). But now that my Selenium RC adventure is moving from a POC to be something that I actually use, I'm running into a problem. It is insanely slow. Executing a single test that loads a page, fills in some fields, and clicks a button takes in the magnitude of seconds to execute. When it is executing, I can easily see each individual field being filled out one at a time. Using Selenium IDE in Firefox is not that slow. I found this page, that clearly specifies that Selenium RC is slow http://selenium-grid.seleniumhq.org/how_it_works.html But why is that? Is it because the browser is polling the selenium server? If so, can this polling interval not be modified? Or is there another reason. I am not accustomed to a remote call taking a humanly noticable amount of time to execute. It is horrible that executing a few tests should take so long. I can execute my entire presentation (MVP), business, and database layer test suite (500+ tests) way quicker than it takes to run 10 tests for a single web page.
