  • Grep-ing gzipped files [duplicate]

    - by Julien Genestoux
    This question already has an answer here: Grepping through .gz log files 5 answers I have a set of 100 log files, compressed using gzip. I need to find all lines matching a given expression. I'd use grep, but of course, that's a bit of a nightmare because I'll have to unzip all files, one by one, grep them and delete the unzipped version, because they wouldn't all fit on my sevrer if they were all unzipped. Anyone has a little trick on how to get that done quickly?

  • Detach an entity from a JPA persistence context (JPA 2.0 / Hibernate / EJB 3 / J2EE 6)

    - by Julien
    Hi, I wrote a stateless EJB method allowing to get an entity in "read-only" mode. The way to do this is to get the entity with the EntityManager then detach it (using the JPA 2.0 EntityManager). My code is the following: @PersistenceContext private EntityManager entityManager; public T getEntity(int entityId, Class<T> specificClass, boolean readOnly) throws Exception{ try{ T entity = (T)entityManager.find(specificClass, entityId); if (readOnly){ entityManager.detach(entity); } return entity; }catch (Exception e){ logger.error("", e); throw e; } } Getting the entity works fine, but the call to the detach method returns the following error: GRAVE: javax.ejb.EJBException at ... Caused by: java.lang.AbstractMethodError: org.hibernate.ejb.EntityManagerImpl.detach(Ljava/lang/Object;)V at com.sun.enterprise.container.common.impl.EntityManagerWrapper.detach(EntityManagerWrapper.java:973) at com.mycomp.dal.MyEJB.getEntity(MyEJB.java:37) I can't get more information and don't understand what the problem is... Could somebody help ?

  • Exception when creating MailMessage

    - by Julien Poulin
    I'm getting a FormatException telling me the address '[email protected]' is invalid (I'm guessing because of the '-'). Here is the code I'm using: var md = new MailDefinition(); md.BodyFileName = physicalPath; md.Subject = subject; md.From = from; md.CC = cc; md.IsBodyHtml = true; MailMessage mailMessage = md.CreateMailMessage(to, replacements, owner); Is there a bug in the .Net e-mail parser? I am sure this address is valid since it belongs to a friend and I have no problem sending and receiving his e-mails with Outlook. Is there a way to fix this? EDIT: Here is the stacktrace: [FormatException: La chaîne spécifiée n'est pas de la forme requise pour une adresse de messagerie.] System.Net.Mime.MailBnfHelper.ReadMailAddress(String data, Int32& offset, String& displayName) +1141755 System.Net.Mail.MailAddress.ParseValue(String address) +240 System.Net.Mail.MailAddress..ctor(String address, String displayName, Encoding displayNameEncoding) +85 System.Net.Mail.Message..ctor(String from, String to) +122 System.Net.Mail.MailMessage..ctor(String from, String to) +114 System.Web.UI.WebControls.MailDefinition.CreateMailMessage(String recipients, IDictionary replacements, String body, Control owner) +1366 System.Web.UI.WebControls.MailDefinition.CreateMailMessage(String recipients, IDictionary replacements, Control owner) +290 WebNotificationManager.CreateMessage(Page owner, MessageTemplate messageTemplate, ListDictionary replacements, String to, String from, String cc, String subject) in c:\dev\SoccerMania\SoccerMania\App_Code\WebNotificationManager.cs:41 WebNotificationManager.SendMessage(Page owner, MessageTemplate messageTemplate, ListDictionary replacements, String to, String subject) in c:\dev\SoccerMania\SoccerMania\App_Code\WebNotificationManager.cs:22 inscription.bInscription_Click(Object sender, EventArgs e) in c:\dev\SoccerMania\SoccerMania\Inscription.aspx.cs:54 System.Web.UI.WebControls.LinkButton.OnClick(EventArgs e) +111 System.Web.UI.WebControls.LinkButton.RaisePostBackEvent(String eventArgument) +79 System.Web.UI.WebControls.LinkButton.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13 System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

  • WatiN or Selenium?

    - by David Thomas Garcia
    I'm going to start building some automated tests of our presentation soon. It seems that everyone recommends WatiN and Selenium. Which do you prefer for automated testing of ASP.NET web forms? Why did that product work better for you? As a side note, I noticed that WatiN 2.0 has been in CTP since March 2008, is that something to be concerned about?

  • Linq to Entities : using ToLower() on NText fields

    - by Julien N
    I'm using SQL Server 2005, with a case sensitive database.. In a search function, I need to create a Linq To Entities (L2E) query with a "where" clause that compare several strings with the data in the database with these rules : The comparison is a "Contains" mode, not strict compare : easy as the string's Contains() method is allowed in L2E The comparison must be case insensitive : I use ToLower() on both elements to perform an insensitive comparison. All of this performs really well but I ran into the following Exception : "Argument data type ntext is invalid for argument 1 of lower function" on one of my fields. It seems that the field is a NText field and I can't perform a ToLower() on that. What could I do to be able to perform a case insensitive Contains() on that NText field ?

  • Is there a rails3-compatible emacs mode yet ?

    - by julien
    Rinari hasn't been updated in the last few months, and there doesn't seem to be such progress made in the branches on github. I've never tried emacs-rails, but from what I can see, the same applies. So, is there a rails mode somewhere that's compatible with v3 ?

  • Gridview sorting: SortDirection always Ascending

    - by Julien N
    Hi ! I have a gridview and I need to sort its elements when the user clicks on the header. Its datasource is a List object. The aspx is defined this way : <asp:GridView ID="grdHeader" AllowSorting="true" AllowPaging="false" AutoGenerateColumns="false" Width="780" runat="server" OnSorting="grdHeader_OnSorting" EnableViewState="true"> <Columns> <asp:BoundField DataField="Entitycode" HeaderText="Entity" SortExpression="Entitycode" /> <asp:BoundField DataField="Statusname" HeaderText="Status" SortExpression="Statusname" /> <asp:BoundField DataField="Username" HeaderText="User" SortExpression="Username" /> </Columns> </asp:GridView> The code behind is defined this way : First load : protected void btnSearch_Click(object sender, EventArgs e) { List<V_ReportPeriodStatusEntity> items = GetPeriodStatusesForScreenSelection(); this.grdHeader.DataSource = items; this.grdHeader.DataBind(); } when the user clicks on headers : protected void grdHeader_OnSorting(object sender, GridViewSortEventArgs e) { List<V_ReportPeriodStatusEntity> items = GetPeriodStatusesForScreenSelection(); items.Sort(new Helpers.GenericComparer<V_ReportPeriodStatusEntity>(e.SortExpression, e.SortDirection)); grdHeader.DataSource = items; grdHeader.DataBind(); } My problem is that e.SortDirection is always set to Ascending. I have webpage with a similar code and it works well, e.SortDirection alternates between Ascending and Descending. What did I do wrong ?

  • Fluent NHibernate OptimisticLock.None() causes "The string 'none' is not a valid Boolean value."

    - by David Thomas Garcia
    I'm using the following mapping: public class LoadMap : IAutoMappingOverride<Load> { public void Override(AutoMapping<Load> mapping) { mapping.HasMany(x => x.Bids).OptimisticLock.None(); mapping.Version(x => x.Version); } } But when I try to create the session I get the following exception: [FormatException: The string 'none' is not a valid Boolean value.] [XmlSchemaValidationException: The 'optimistic-lock' attribute is invalid - The value 'none' is invalid according to its datatype 'http://www.w3.org/2001/XMLSchema:boolean' - The string 'none' is not a valid Boolean value.] I'm using NHibernate 2.1.2.4000 and I was using Fluent NHibernate 1.0RTM, but tried the latest build 636 just to be sure this isn't something that was fixed recently or something. As a side note, in case I'm doing this all wrong, I would like to be able to make changes to the .Bids list without incrementing Version. I saw an example on Ayende's blog that did what I wanted with properties.

  • ASP.NET MVC POST Parameter into RouteData

    - by David Thomas Garcia
    I'm using jQuery to POST an Id to my route, for example: http://localhost:1234/Load/Delete with a POST Parameter Id = 1 I'm only using the default route in Global.asax.cs right now: routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); When I perform the POST, in my ActionFilter filterContext.RouteData.Values["Id"] is set to the default value of "". Ideally, I'd like it to use the POST Parameter value automatically if the URL comes up with "". I know it is posting properly because I can see the value of "1" in filterContext.HttpContext.Request.Params["Id"]. Is there a way to get RouteData to use a POST parameter as a fall back value?

  • Clojure editor/IDE recommendations on OS X

    - by Julien Chastang
    I am starting to learn the Clojure programming language. Are there any recommendations for Clojure editors/IDEs on OS X? Update 2009-9-23: The clojure space has changed tremendously since I originally posted this question. Many of the links below, especially those that refer to clojure-mode with emacs, are out-of-date. The best clojure IDE I found was the enclojure Netbeans plugin which was recently released (2009-08-25). Update 2010-4-30: Here is another very good link on this subject by Lau B. Jensen. Also, for my own clojure development, I have actually moved to emacs / swank-clojure.

  • Which conveniences does CEDET bring to dynamic languages ?

    - by julien
    I've been looking into CEDET, but it seems that most of its features would appeal more to developpers working in statically typed languages, and I'm kind of getting cold feet from the amount of tinkering it seems to require. As I work mainly with ruby and javascript, I'm wondering what kind of improvements it could bring when working with these dynamic languages, over a plain TAGS file ?

  • Default value for field in Django model

    - by Daniel Garcia
    Suppose I have a model: class SomeModel(models.Model): id = models.AutoField(primary_key=True) a = models.IntegerField(max_length=10) b = models.CharField(max_length=7) Currently I am using the default admin to create/edit objects of this type. How do I set the field 'a' to have the same number as id? (default=???) Other question Suppose I have a model: event_date = models.DateTimeField( null=True) year = models.IntegerField( null=True) month = models.CharField(max_length=50, null=True) day = models.IntegerField( null=True) How can i set the year, month and day fields by default to be the same as event_date field?

  • Mock versus Implementation. How to share both approaches in a single Test class ?

    - by Arthur Ronald F D Garcia
    Hi, See the following Mock Test by using Spring/Spring-MVC public class OrderTest { // SimpleFormController private OrderController controller; private OrderService service; private MockHttpServletRequest request; @BeforeMethod public void setUp() { request = new MockHttpServletRequest(); request.setMethod("POST"); Integer orderNumber = 421; Order order = new Order(orderNumber); // Set up a Mock service service = createMock(OrderService.class); service.save(order); replay(service); controller = new OrderController(); controller.setService(service); controller.setValidator(new OrderValidator()); request.addParameter("orderNumber", String.valueOf(orderNumber)); } @Test public void successSave() { controller.handleRequest(request, new MockHttpServletResponse()); // Our OrderService has been called by our controller verify(service); } @Test public void failureSave() { // Ops... our orderNumber is required request.removeAllParameters(); ModelAndView mav = controller.handleRequest(request, new MockHttpServletResponse()); BindingResult bindException = (BindingResult) mav.getModel().get(BindingResult.MODEL_KEY_PREFIX + "command"); assertEquals("Our Validator has thrown one FieldError", bindException.getAllErrors(), 1); } } As you can see, i do as proposed by Triple A pattern Arrange (setUp method) Act (controller.handleRequest) Assert (verify and assertEquals) But i would like to test both Mock and Implementation class (OrderService) by using this single Test class. So in order to retrieve my Implementation, i re-write my class as follows @ContextConfiguration(locations="/app.xml") public class OrderTest extends AbstractTestNGSpringContextTests { } So how should i write my single test to Arrange both Mock and Implementation OrderService without change my Test method (sucessSave and failureSave) I am using TestNG, but you can show in JUnit if you want regards,
