• How does your team work together in a remote setup?

  - by Carl Rosenberger

  Hi, we are a distributed team working on the object database db4o. The way we work: We try to program in pairs only. We use Skype and VNC or SharedView to connect and work together. In our online Tuesday meeting every week (usually about 1 hour) we talk about the tasks done last week we create new pairs for the next week with a random generator so knowledge and friendship distribute evenly we set the priority for any new tasks or bugs that have come in each team picks the tasks it likes to do from the highest prioritized ones. From Tuesday to Wednesday we estimate tasks. We have a unit of work we call "Ideal Developer Session" (IDS), maybe 2 or 3 hours of working together as a pair. It's not perfectly well defined (because we know estimation always is inaccurate) but from our past shared experience we have a common sense of what an IDS is. If we can't estimate a task because it feels too long for a week we break it down into estimatable smaller tasks. During a short meeting on Wednesday we commit to a workload we feel is well doable in a week. We commit to complete. If a team runs out of committed tasks during the week, it can pick new ones from the prioritized queue we have in Jira. When we started working this way, some of us found that remote pair programming takes a lot of energy because you are so focussed. If you pair program for more than 5 or 6 hours per day, you get drained. On the other hand working like this has turned out to be very efficient. The knowledge about our codebase is evenly distributed and we have really learnt lots from eachother. I would be very interested to hear about the experiences from other teams working in a similar way. Things like: How often do you meet? Have you tried different sprint lengths (one week, two week, longer) ? Which tools do you use? Which issue tracker do you use? What do you do about time zone differences? How does it work for you to integrate new people into the team? How many hours do you usually work per week? How does your management interact with the way you are working? Do you get put on a waterfall with hard deadlines? What's your unit of work? What is your normal velocity? (units of work done per week) Programming work should be fun and for us it usually is great fun. I would be happy about any new ideas how to make it even more fun and/or more efficient.

• Calling Object Methods in Code

  - by Mister R2

  I'm a bit new to PHP, and I'm more experienced with strongly-typed languages such as JAVA, C# or C++.I'm currently writing a web tool in PHP, and I am having an issue trying to do what I want. The simple idea of what I want to do in code is run through some emails I used PHP-IMAP to get. I then create email objects (a class I defined), and put them in an array. Later on the code, however, I cycle through those emails to display them. However, as you might have guessed I'd have an issue with, I try to use an Email Class object method in that later loop -- and I'm pretty sure PHP doesn't know that the variables in the array happen to be Email Class objects! I wrote a toString method, and I want to call it in the loop. While I don't need to do this for the final version of this tool, I would like to find out what I'm missing. This is the class and the loop where I'm calling the method: include 'imap_email_interface.php'; class ImapEmail implements imap_email_interface { // Email data var $msgno; var $to; var $from; var $subject; var $body; var $attachment; // Email behavior /* PHP 4 ~ legacy constructor */ public function ImapEmail($message_number) { $this->__construct(); $this->msgno = $message_number; } /* PHP 5 Constructor */ public function __construct($message_number) { $this->msgno = $message_number; } public function send($send_to) { // Not Yet Needed! Seriously! } public function setHeaderDirectly($TO, $FROM, $SUBJECT) { $this->to = $TO; $this->from = $FROM; $this->subject = $SUBJECT; } public function setHeaderIndirectly($HEADER) { if (isset($HEADER->to[0]->personal)) $this->to = '"'.$HEADER->to[0]->personal.'", '.$HEADER->to[0]->mailbox.'@'.$HEADER->to[0]->host; else $this->to = $HEADER->to[0]->mailbox.'@'.$HEADER->to[0]->host; $this->from = '"'.$HEADER->from[0]->personal.'", '.$HEADER->from[0]->mailbox.'@'.$HEADER->from[0]->host; $this->subject = $HEADER->subject; } public function setBody($BODY) { $this->body = $BODY; } public function setAttachment($ATTCH) { $this->attachment = $ATTCH; } public function toString() { $str = '[TO]: ' . $this->to . '<br />' . '[FROM]: ' . $this->from . '<br />' . '[SUBJECT]: ' . $this->subject . '<br />'; $str .= '[Attachment]: '.$this->attachment.'<br />'; return $str; } } ?> The Loop: foreach ($orderFileEmails as $x) { $x->toString(); echo '<br /><br />'; } Any ideas?

• NHibernate Many-to-Many Mapping not working

  - by ClutchDude

  I have a Nhibernate mapping file for a simple user/role mapping. Here are the mapping files: Users.hbm.xml <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Sample.Persistence" namespace="Sample.Persistence.Model"> <class name="User" table="Users"> <id name="UserKey"> <generator class="identity"/> </id> <property name="UserName" column="UserName" type="String" /> <property name="Password" column="Password" type="Byte[]" /> <property name="FirstName" column="FirstName" type="String" /> <property name="LastName" column="LastName" type="String" /> <property name="Email" column="Email" type="String" /> <property name="Active" column="Active" type="Boolean" /> <property name="Locked" column="Locked" type="Boolean" /> <property name="LoginFailures" column="LoginFailures" type="int" /> <property name="LockoutDate" column="LockoutDate" type="DateTime" generated="insert" /> <property name="Expired" column="Expired" type="Boolean" generated="insert"/> <set name="Roles" table="UsersRolesBridge" lazy="false"> <key column="UserKey" /> <many-to-many class="Role" not-found="exception" column="RoleKey" /> </set> </class> </hibernate-mapping> Role.hbm.xml <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Sample.Persistence" namespace="Sample.Persistence.Model"> <class name="Role" table="Roles"> <id name="RoleKey"> <generator class="identity"/> </id> <property name="Name" column="Name" type="String" /> <set name="Users" inverse="true" atable="UsersRolesBridge" lazy="false" > <key column="RoleKey" /> <many-to-many class="User" column="UserKey" /> </set> </class> </hibernate-mapping> I am able to retrieve roles for each user via NHibernate but when I go to save a new object, the roles are not saved in the Bridge table. The user is created and insert with no issues. I've checked that the Role collection, a field on the user, is being populated with the proper rolekey before the Session.Save() is called. There is no exception thrown as well.

• Methodology for a Rails app

  - by Aaron Vegh

  I'm undertaking a rather large conversion from a legacy database-driven Windows app to a Rails app. Because of the large number of forms and database tables involved, I want to make sure I've got the right methodology before getting too far. My chief concern is minimizing the amount of code I have to write. There are many models that interact together, and I want to make sure I'm using them correctly. Here's a simplified set of models: class Patient < ActiveRecord::Base has_many :PatientAddresses has_many :PatientFileStatuses end class PatientAddress < ActiveRecord::Base belongs_to :Patient end class PatientFileStatus < ActiveRecord::Base belongs_to :Patient end The controller determines if there's a Patient selected; everything else is based on that. In the view, I will be needing data from each of these models. But it seems like I have to write an instance variable in my controller for every attribute that I want to use. So I start writing code like this: @patient = Patient.find(session[:patient]) @patient_addresses = @patient.PatientAddresses @patient_file_statuses = @patient.PatientFileStatuses @enrollment_received_when = @patient_file_statuses[0].EnrollmentReceivedWhen @consent_received = @patient_file_statuses[0].ConsentReceived @consent_received_when = @patient_file_statuses[0].ConsentReceivedWhen The first three lines grab the Patient model and its relations. The next three lines are examples of my providing values to the view from one of those relations. The view has a combination of text fields and select fields to show the data above. For example: <%= select("patientfilestatus", "ConsentReceived", {"val1"="val1", "val2"="val2", "Written"="Written"}, :include_blank=true )% <%= calendar_date_select_tag "patient_file_statuses[EnrollmentReceivedWhen]", @enrollment_complete_when, :popup=:force % (BTW, the select tag isn't really working; I think I have to use collection_select?) My questions are: Do I have to manually declare the value of every instance variable in the controller, or can/should I do it within the view? What is the proper technique for displaying a select tag for data that's not the primary model? When I go to save changes to this form, will I have to manually pick out the attributes for each model and save them individually? Or is there a way to name the fields such that ActiveRecord does the right thing? Thanks in advance, Aaron.

• Select latest group by in nhibernate

  - by Kendrick

  I have Canine and CanineHandler objects in my application. The CanineHandler object has a PersonID (which references a completely different database), an EffectiveDate (which specifies when a handler started with the canine), and a FK reference to the Canine (CanineID). Given a specific PersonID, I want to find all canines they're currently responsible for. The (simplified) query I'd use in SQL would be: Select Canine.* from Canine inner join CanineHandler on(CanineHandler.CanineID=Canine.CanineID) inner join (select CanineID,Max(EffectiveDate) MaxEffectiveDate from caninehandler group by CanineID) as CurrentHandler on(CurrentHandler.CanineID=CanineHandler.CanineID and CurrentHandler.MaxEffectiveDate=CanineHandler.EffectiveDate) where CanineHandler.HandlerPersonID=@PersonID Edit: Added mapping files below: <class name="CanineHandler" table="CanineHandler" schema="dbo"> <id name="CanineHandlerID" type="Int32"> <generator class="identity" /> </id> <property name="EffectiveDate" type="DateTime" precision="16" not-null="true" /> <property name="HandlerPersonID" type="Int64" precision="19" not-null="true" /> <many-to-one name="Canine" class="Canine" column="CanineID" not-null="true" access="field.camelcase-underscore" /> </class> <class name="Canine" table="Canine"> <id name="CanineID" type="Int32"> <generator class="identity" /> </id> <property name="Name" type="String" length="64" not-null="true" /> ... <set name="CanineHandlers" table="CanineHandler" inverse="true" order-by="EffectiveDate desc" cascade="save-update" access="field.camelcase-underscore"> <key column="CanineID" /> <one-to-many class="CanineHandler" /> </set> <property name="IsDeleted" type="Boolean" not-null="true" /> </class> I haven't tried yet, but I'm guessing I could do this in HQL. I haven't had to write anything in HQL yet, so I'll have to tackle that eventually anyway, but my question is whether/how I can do this sub-query with the criterion/subqueries objects. I got as far as creating the following detached criteria: DetachedCriteria effectiveHandlers = DetachedCriteria.For<Canine>() .SetProjection(Projections.ProjectionList() .Add(Projections.Max("EffectiveDate"),"MaxEffectiveDate") .Add(Projections.GroupProperty("CanineID"),"handledCanineID") ); but I can't figure out how to do the inner join. If I do this: Session.CreateCriteria<Canine>() .CreateCriteria("CanineHandler", "handler", NHibernate.SqlCommand.JoinType.InnerJoin) .List<Canine>(); I get an error "could not resolve property: CanineHandler of: OPS.CanineApp.Model.Canine". Obviously I'm missing something(s) but from the documentation I got the impression that should return a list of Canines that have handlers (possibly with duplicates). Until I can make this work, adding the subquery isn't going to work... I've found similar questions, such as http://stackoverflow.com/questions/747382/only-get-latest-results-using-nhibernate but none of the answers really seem to apply with the kind of direct result I'm looking for. Any help or suggestion is greatly appreciated.

• invalid postback event instead of dropdown to datagrid

  - by rima

  I faced with funny situation. I created a page which is having some value, I set these value and control my post back event also. The problem is happening when I change a component index(ex reselect a combobox which is not inside my datagrid) then I dont know why without my page call the Page_Load it goes to create a new row in grid function and all of my parameter are null! I am just receiving null exception. So in other word I try to explain the situation: when I load my page I am initializing some parameter. then everything is working fine. in my page when I change selected item of my combo box, page suppose to go and run function related to that combo box, and call page_load, but it is not going there and it goes to rowcreated function. I am trying to illustrate part of my page. Please help me because I am not receiving any error except null exception and it triger wrong even which seems so complicated for me. public partial class W_CM_FRM_02 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack && !loginFail) return; InitializeItems(); } } private void InitializeItems() { cols = new string[] { "v_classification_code", "v_classification_name" }; arrlstCMMM_CLASSIFICATION = (ArrayList)db.Select(cols, "CMMM_CLASSIFICATION", "v_classification_code <> 'N'", " ORDER BY v_classification_name"); } } protected void DGV_RFA_DETAILS_RowCreated(object sender, GridViewRowEventArgs e) { //db = (Database)Session["oCon"]; foreach (DataRow dr in arrlstCMMM_CLASSIFICATION) ((DropDownList)DGV_RFA_DETAILS.Rows[index].Cells[4].FindControl("OV_RFA_CLASSIFICATION")).Items.Add(new ListItem(dr["v_classification_name"].ToString(), dr["v_classification_code"].ToString())); } protected void V_CUSTOMER_SelectedIndexChanged(object sender, EventArgs e) { if (V_CUSTOMER.SelectedValue == "xxx" || V_CUSTOMER.SelectedValue == "ddd") V_IMPACTED_FUNCTIONS.Enabled = true; } } my form: <%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="W_CM_FRM_02.aspx.cs" Inherits="W_CM_FRM_02" Title="W_CM_FRM_02" enableeventvalidation="false" EnableViewState="true"%> <td>Project name*</td> <td><asp:DropDownList ID="V_CUSTOMER" runat="server" AutoPostBack="True" onselectedindexchanged="V_CUSTOMER_SelectedIndexChanged" /></td> <td colspan = "8"> <asp:GridView ID="DGV_RFA_DETAILS" runat="server" ShowFooter="True" AutoGenerateColumns="False" CellPadding="1" ForeColor="#333333" GridLines="None" OnRowDeleting="grvRFADetails_RowDeleting" Width="100%" Style="text-align: left" onrowcreated="DGV_RFA_DETAILS_RowCreated"> <RowStyle BackColor="#FFFBD6" ForeColor="#333333" /> <Columns> <asp:BoundField DataField="ON_RowNumber" HeaderText="SNo" /> <asp:TemplateField HeaderText="RFA/RAD/Ticket No*"> <ItemTemplate> <asp:TextBox ID="OV_RFA_NO" runat="server" Width="120"></asp:TextBox> </ItemTemplate> </asp:TemplateField>

• how to add multiple filters to pagination?

  - by ClarkSKent

  Hey, I am trying to allow multiple filters to be selected for my pagination script. So in my pagination, when a user clicks the 'marketing' button(link) it queries the database just for the category that = marketing. The same goes for the other 2 filter buttons as seen in the script below. (automotive, sports). The problem is, I want to be able to select multiple filters like only marketing and auomotive or automotive and sports, for example if I click the marketing filter and then the automotive, it would display the categories that equal marketing, and automotive. I have no idea how to accomplish this, so I have come to the experts to help me out. This is the script I am working on (I am very new to PHP and programming in general): <h3>Filter results by:</h3> <a href='pagi_test.php?category=marketing'>marketing</a> <a href='pagi_test.php?category=automotive'>automotive</a> <a href='pagi_test.php?category=sports'>sports</a> <br /> <h3>Results:</h3> <?php //connecting to the database $error = "Could not connect to the database"; mysql_connect('localhost','root','root') or die($error); mysql_select_db('ajax_demo') or die($error); //max displayed per page $per_page = 3; //get start variable $start = $_GET['start']; $category = mysql_real_escape_string($_GET['category']); //count records $record_count = mysql_num_rows(mysql_query("SELECT * FROM explore WHERE category='$category'")); //count max pages $max_pages = $record_count / $per_page; //may come out as decimal if (!$start) $start = 0; //display data $get = mysql_query("SELECT * FROM explore WHERE category='$category' LIMIT $start, $per_page"); ?> <table width="800px"> <?php while ($row = mysql_fetch_assoc($get)) { // get data $id = $row['id']; $site_name = $row['site_name']; $site_description = $row['site_description']; ?> <tr> <td><?php echo $id; ?></td> <td><?php echo $site_name; ?></td> <td><?php echo $site_description; ?></td> </tr> <?php } //setup prev and next variables $prev = $start - $per_page; $next = $start + $per_page; //show prev button if (!($start<=0)) echo "<a href='pagi_test.php?category=$category&start=$prev'>Prev</a> "; //show page numbers //set variable for first page $i=1; for ($x=0;$x<$record_count;$x=$x+$per_page) { if ($start!=$x) echo " <a href='pagi_test.php?category=$category&start=$x'>$i</a> "; else echo " <a href='pagi_test.php?category=$category&start=$x'><b>$i</b></a> "; $i++; } //show next button if (!($start>=$record_count-$per_page)) echo " <a href='pagi_test.php?category=$category&start=$next'>Next</a>"; ?>

• Fastest way to pad a number in Java to a certain number of digits

  - by Martin

  Am trying to create a well-optimised bit of code to create number of X-digits in length (where X is read from a runtime properties file), based on a DB-generated sequence number (Y), which is then used a folder-name when saving a file. I've come up with three ideas so far, the fastest of which is the last one, but I'd appreciate any advice people may have on this... 1) Instantiate a StringBuilder with initial capacity X. Append Y. While length < X, insert a zero at pos zero. 2) Instantiate a StringBuilder with initial capacity X. While length < X, append a zero. Create a DecimalFormat based on StringBuilder value, and then format the number when it's needed. 3) Create a new int of Math.pow( 10, X ) and add Y. Use String.valueOf() on the new number and then substring(1) it. The second one can obviously be split into outside-loop and inside-loop sections. So, any tips? Using a for-loop of 10,000 iterations, I'm getting similar timings from the first two, and the third method is approximately ten-times faster. Does this seem correct? Full test-method code below... // Setup test variables int numDigits = 9; int testNumber = 724; int numIterations = 10000; String folderHolder = null; DecimalFormat outputFormat = new DecimalFormat( "#,##0" ); // StringBuilder test long before = System.nanoTime(); for ( int i = 0; i < numIterations; i++ ) { StringBuilder sb = new StringBuilder( numDigits ); sb.append( testNumber ); while ( sb.length() < numDigits ) { sb.insert( 0, 0 ); } folderHolder = sb.toString(); } long after = System.nanoTime(); System.out.println( "01: " + outputFormat.format( after - before ) + " nanoseconds" ); System.out.println( "Sanity check: Folder = \"" + folderHolder + "\"" ); // DecimalFormat test before = System.nanoTime(); StringBuilder sb = new StringBuilder( numDigits ); while ( sb.length() < numDigits ) { sb.append( 0 ); } DecimalFormat formatter = new DecimalFormat( sb.toString() ); for ( int i = 0; i < numIterations; i++ ) { folderHolder = formatter.format( testNumber ); } after = System.nanoTime(); System.out.println( "02: " + outputFormat.format( after - before ) + " nanoseconds" ); System.out.println( "Sanity check: Folder = \"" + folderHolder + "\"" ); // Substring test before = System.nanoTime(); int baseNum = (int)Math.pow( 10, numDigits ); for ( int i = 0; i < numIterations; i++ ) { int newNum = baseNum + testNumber; folderHolder = String.valueOf( newNum ).substring( 1 ); } after = System.nanoTime(); System.out.println( "03: " + outputFormat.format( after - before ) + " nanoseconds" ); System.out.println( "Sanity check: Folder = \"" + folderHolder + "\"" );

• How do I write object classes effectively when dealing with table joins?

  - by Chris

  I should start by saying I'm not now, nor do I have any delusions I'll ever be a professional programmer so most of my skills have been learned from experience very much as a hobby. I learned PHP as it seemed a good simple introduction in certain areas and it allowed me to design simple web applications. When I learned about objects, classes etc the tutor's basic examnples covered the idea that as a rule of thumb each database table should have its own class. While that worked well for the photo gallery project we wrote, as it had very simple mysql queries, it's not working so well now my projects are getting more complex. If I require data from two separate tables which require a table join I've instead been ignoring the class altogether and handling it on a case by case basis, OR, even worse been combining some of the data into the class and the rest as a separate entity and doing two queries, which to me seems inefficient. As an example, when viewing content on a forum I wrote, if you view a thread, I retrieve data from the threads table, the posts table and the user table. The queries from the user and posts table are retrieved via a join and not instantiated as an object, whereas the thread data is called using my Threads class. So how do I get from my current state of affairs to something a little less 'stupid', for want of a better word. Right now I have a DB class that deals with connection and escaping values etc, a parent db query class that deals with the common queries and methods, and all of the other classes (Thread, Upload, Session, Photo and ones thats aren't used Post, User etc ) are children of that. Do I make a big posts class that has the relevant extra attributes that I retrieve from the users (and potentially threads) table? Do I have separate classes that populate each of their relevant attributes with a single query? If so how do I do that? Because of the way my classes are written, based on what I was taught, my db update row method, or insert method both just take the attributes as an array and update all of that, if I have extra attributes from other db tables in each class then how do I rewrite those methods as obbiously updating automatically like that would result in errors? In short I think my understanding is limited right now and I'd like some pointers when it comes to the fundamentals of how to write more complex classes.

• Trying to create an image list based on what is defined as the order, and loosing

  - by user1691463

  I have a custom created module for Joomla 2.5 and within the params of the module, and have a loop that is not outputting as expected. I have the following parameters (fields) int he module: Order Thumb image Image Title Full-size image Now there are 10 sets of these group of 4 params. What I am trying to do is loop through each of the object sets, 10 of them, and on each iteration, build an HTML image list structure. The if statement is building the HTML structure for the sets that have an order value that is greater than 0, and the else is creating the html for those sets that do not have a value greater that 0. The goal is to create two variables and then concatenate the the strings together; the leading set are the sets that have an order defined. This is not happening and every thrid loop seems like it is missing. Here is the order as it is set in the 10 sets Set 1 = 0 Set 2 = 4 Set 3 = 1 Set 4 = 0 Set 5 = 5 Set 6 = 0 Set 7 = 0 Set 8 = 6 Set 9 = 3 Set 10 = 9 However, the outcomes is: 9 5 1 4 6 7 10 Instead of the expected: 3 9 2 5 8 1 (below here are those sets that were not greater than 0 in order of appearance) 4 6 7 whats wrong here that I can not see <?php for ($i = 1; $i <= 10; $i++) { $order = $params->get('order'.$i);#get order for main loop of 10 $active = ""; if ($order > 0) {#Check if greater than 0 for ($n = 1; $n <= 10; $n++) {#loop through all order fields looking and build html lowest to highest; $ordercheck =$params->get('order'.$n); if ($ordercheck == $i) { $img = $params->get('image'.$n); $fimage = $params->get('image'.$n.'fullimage'); $title = $params->get('image'.$n.'alttext'); $active = ""; $active = $active . '<li>'; $active = $active . '<a href="'.$fimage.'" rel="prettyPhoto[gallery1]" title="'.$title.'">'; $active = $active . '<img src="'.$img.'" alt="'.$title.'" />'; $active = $active .

• cflock do not throw timeout for same url called in same browser

  - by Pritesh Patel

  I am trying lock block on page test.cfm and below is code written on page. <cfscript> writeOutput("Before lock at #now()#"); lock name="threadlock" timeout="3" type="exclusive" { writeOutput("<br/>started at #now()#"); thread action="sleep" duration="10000"; writeOutput("<br/>ended at #now()#"); } writeOutput("<br/>After lock at #now()#"); </cfscript> assuming my url for page is http://localhost.local/test.cfm and running it on browser in two different tabs. I was expecting one of the url will throw timeout error after 3 second since another url lock it atleast for 10 seconds due to thread sleep. Surprisingly I do not get any timeout error rather second page call run after 10 seconds as first call finish execution. But I am appending some url parameter (e.g. http://localhost.local/test.cfm?q=1) will throw error. Also I am calling same url in different browser then one of the call will throw timeout issue. Is lock based on session and url? Update Here is output for two different cases: Case 1: TAB1 Url: http://localhost.local/test/test.cfm Before lock at {ts '2013-10-18 09:21:35'} started at {ts '2013-10-18 09:21:35'} ended at {ts '2013-10-18 09:21:45'} After lock at {ts '2013-10-18 09:21:45'} TAB2 Url: http://localhost.local/test/test.cfm Before lock at {ts '2013-10-18 09:21:45'} started at {ts '2013-10-18 09:21:45'} ended at {ts '2013-10-18 09:21:55'} After lock at {ts '2013-10-18 09:21:55'} Case 2: TAB1 Url: http://localhost.local/test/test.cfm Before lock at {ts '2013-10-18 09:27:18'} started at {ts '2013-10-18 09:27:18'} ended at {ts '2013-10-18 09:27:28'} After lock at {ts '2013-10-18 09:27:28'} TAB2 Url: http://localhost.local/test/test.cfm? (Added ? at the end) Before lock at {ts '2013-10-18 09:27:20'} A timeout occurred while attempting to lock threadlock. The error occurred in C:/inetpub/wwwroot/test/test.cfm: line 13 11 : 12 : <cfoutput>Before lock at #now()#</cfoutput> 13 : <cflock name="threadlock" timeout="3" type="exclusive"> 14 : <cfoutput><br/>started at #now()#</cfoutput> 15 : <cfthread action="sleep" duration="10000"/> ... Result for case 2 as expected. For case 1, strange thing I just noticed is tab 2 output "Before lock at {ts '2013-10-18 09:21:45'} indicates that whole request start after 10 seconds (means after the complete execution of first tab) when I have fired it in second URL just after 2 seconds of first tabs.

• How to page multiple data sets in ASP.NET MVC

  - by REA_ANDREW

  On a single view I will have three sets of paged data. Which means for each model I will have The Objects The Page Index The Page Size My initial thought was for example: public class PagedModel<T> where T:class { public IList<T> Objects { get; set; } public int ModelPageIndex { get; set; } public int ModelPageSize { get; set; } } Then having a model which is to be supplied to the action as for example: public class TypesViewModel { public PagedModel<ObjectA> Types1 { get; set; } public PagedModel<ObjectB> Typed2 { get; set; } public PagedModel<ObjectC> Types3 { get; set; } } So if I then for example have the Index view inherit from the type: System.Web.Mvc.ViewPage<uk.co.andrewrea.forum.Web.Models.TypesViewModel> Now my initial aciton method for the index is simply: public ActionResult Index() { var forDisplayPurposes = new TypesViewModel(); return View(forDisplayPurposes); } If I then want to page, it is here where I am struggling to decide which action to take. Lets say that I select the next page of the Types2 PageModel. What should the action look like for this in order to return the new view showing the second page of the Types2 PageModel I was thinking possibly to duplicate the action but use it with POST [AcceptVerbs(HttpVerbs.Post)] public ActionResult Index(TypesViewModel model) { return View(model); } Is this a good way to approach it. I understand there is always Session, but I was just wondering how such a thing is achieved currently out there. If any best methods have been mutually accepted and things. So simply, one page with multiple paged models. How to persist the data for each using a wrapper model. Which way should you pass in the model and which way should you page the data, i.e. Form Post Lastly, I have seen the routes take this into account i.e. {controller}/{action}/{id}/{pageindex}/{pagesize} but this only accounts for one model and I do not really wwant to repeat the pagesize and pageindex values for the number of models I have inside the wrapper model. Thanks for your time!! Andrew

• hosting simple python scripts in a container to handle concurrency, configuration, caching, etc.

  - by Justin Grant

  My first real-world Python project is to write a simple framework (or re-use/adapt an existing one) which can wrap small python scripts (which are used to gather custom data for a monitoring tool) with a "container" to handle boilerplate tasks like: fetching a script's configuration from a file (and keeping that info up to date if the file changes and handle decryption of sensitive config data) running multiple instances of the same script in different threads instead of spinning up a new process for each one expose an API for caching expensive data and storing persistent state from one script invocation to the next Today, script authors must handle the issues above, which usually means that most script authors don't handle them correctly, causing bugs and performance problems. In addition to avoiding bugs, we want a solution which lowers the bar to create and maintain scripts, especially given that many script authors may not be trained programmers. Below are examples of the API I've been thinking of, and which I'm looking to get your feedback about. A scripter would need to build a single method which takes (as input) the configuration that the script needs to do its job, and either returns a python object or calls a method to stream back data in chunks. Optionally, a scripter could supply methods to handle startup and/or shutdown tasks. HTTP-fetching script example (in pseudocode, omitting the actual data-fetching details to focus on the container's API): def run (config, context, cache) : results = http_library_call (config.url, config.http_method, config.username, config.password, ...) return { html : results.html, status_code : results.status, headers : results.response_headers } def init(config, context, cache) : config.max_threads = 20 # up to 20 URLs at one time (per process) config.max_processes = 3 # launch up to 3 concurrent processes config.keepalive = 1200 # keep process alive for 10 mins without another call config.process_recycle.requests = 1000 # restart the process every 1000 requests (to avoid leaks) config.kill_timeout = 600 # kill the process if any call lasts longer than 10 minutes Database-data fetching script example might look like this (in pseudocode): def run (config, context, cache) : expensive = context.cache["something_expensive"] for record in db_library_call (expensive, context.checkpoint, config.connection_string) : context.log (record, "logDate") # log all properties, optionally specify name of timestamp property last_date = record["logDate"] context.checkpoint = last_date # persistent checkpoint, used next time through def init(config, context, cache) : cache["something_expensive"] = get_expensive_thing() def shutdown(config, context, cache) : expensive = cache["something_expensive"] expensive.release_me() Is this API appropriately "pythonic", or are there things I should do to make this more natural to the Python scripter? (I'm more familiar with building C++/C#/Java APIs so I suspect I'm missing useful Python idioms.) Specific questions: is it natural to pass a "config" object into a method and ask the callee to set various configuration options? Or is there another preferred way to do this? when a callee needs to stream data back to its caller, is a method like context.log() (see above) appropriate, or should I be using yield instead? (yeild seems natural, but I worry it'd be over the head of most scripters) My approach requires scripts to define functions with predefined names (e.g. "run", "init", "shutdown"). Is this a good way to do it? If not, what other mechanism would be more natural? I'm passing the same config, context, cache parameters into every method. Would it be better to use a single "context" parameter instead? Would it be better to use global variables instead? Finally, are there existing libraries you'd recommend to make this kind of simple "script-running container" easier to write?

• ActionScript MovieClip moves to the left, but not the right

  - by Defcon

  I have a stage with a movie clip with the instance name of "mc". Currently I have a code that is suppose to move the player left and right, and when the left or right key is released, the "mc" slides a little bit. The problem I'm having is that making the "mc" move to the left works, but the exact some code used for the right doesn't. All of this code is present on the Main Stage - Frame One //Variables var mcSpeed:Number = 0;//MC's Current Speed var mcJumping:Boolean = false;//if mc is Jumping var mcFalling:Boolean = false;//if mc is Falling var mcMoving:Boolean = false;//if mc is Moving var mcSliding:Boolean = false;//if mc is sliding var mcSlide:Number = 0;//Stored for use when creating slide var mcMaxSlide:Number = 1.6;//Max Distance the object will slide. //Player Move Function p1Move = new Object(); p1Move = function (dir:String, maxSpeed:Number) { if (dir == "left" && _root.mcSpeed<maxSpeed) { _root.mcSpeed += .2; _root.mc._x -= _root.mcSpeed; } else if (dir == "right" && _root.mcSpeed<maxSpeed) { _root.mcSpeed += .2; _root.mc._x += _root.mcSpeed; } else if (dir == "left" && speed>=maxSpeed) { _root.mc._x -= _root.mcSpeed; } else if (dir == "right" && _root.mcSpeed>=maxSpeed) { _root.mc._x += _root.mcSpeed; } } //onEnterFrame for MC mc.onEnterFrame = function():Void { if (Key.isDown(Key.LEFT)) { if (_root.mcMoving == false && _root.mcSliding == false) { _root.mcMoving = true; } else if (_root.mcMoving == true && _root.mcSliding == false) { _root.p1Move("left",5); } } else if (!Key.isDown(Key.LEFT)) { if (_root.mcMoving == true && _root.mcSliding == false) { _root.mcSliding = true; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide<_root.mcMaxSlide) { _root.mcSlide += .2; this._x -= .2; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide>=_root.mcMaxSlide) { _root.mcMoving = false; _root.mcSliding = false; _root.mcSlide = 0; _root.mcSpeed = 0; } } else if (Key.isDown(Key.RIGHT)) { if (_root.mcMoving == false && _root.mcSliding == false) { _root.mcMoving = true; } else if (_root.mcMoving == true && _root.mcSliding == false) { _root.p1Move("right",5); } } else if (!Key.isDown(Key.RIGHT)) { if (_root.mcMoving == true && _root.mcSliding == false) { _root.mcSliding = true; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide<_root.mcMaxSpeed) { _root.mcSlide += .2; this._x += .2; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide>=_root.mcMax) { _root.mcMoving = false; _root.mcSliding = false; _root.mcSlide = 0; _root.mcSpeed = 0; } } }; I just don't get why when you press the left arrow its works completely fine, but when you press the right arrow it doesn't respond. It is literally the same code.

• Mac Safari randomly recreating cookie when I refresh my login screen. Very bizarre

  - by mcintyre321

  We have found an issue in our app where Safari on the Mac randomly recreates a login cookie from a logged off session. I have a fiddler archive with this behaviour here. Note that some stuff has been removed from this to make it easier to get, but nothing which sets a cookie or anything has been taken out - only repetitions of requests 3-8. I'll talk you through the running order Request 1: user logs out via call to /logout.aspx - Set-Cookie returned setting cookie expiry date to 1999 Requests 2-8: user refreshes login page sending calls to root or /res/en-US/s.js - no cookie is sent to server or received back, and access is denied. I have cut out a lot of requests of this nature from the log as they are boring Request 9: request for /res/en-US/s.js - Hv3 authentication cookie has mysteriously reappeared! Wat. There was NO set-cookie! WTFF! Request 10+ : now the cookie has reappeared, the site logs the user in AGAIN The cookie, when examined in Safari looks like <dict> <key>Created</key> <real>259603523.26834899</real> <key>Domain</key> <string>.mysite.dev</string> <key>Expires</key> <date>2010-03-24T16:05:22Z</date> <key>HttpOnly</key> <string>TRUE</string> <key>Name</key> <string>.Hv3</string> <key>Path</key> <string>/</string> </dict> One thing to note is that in Safari, the cookie domain is .mysite.dev not mysite.dev (which is the cookie domain specified in web.config) - however, given that access is denied in requests 2-8, it looks like the cookie has expired OK. If you look in the list of cookies in the browser during 2-8, the .Hv3 cookie is not there. Is this our bug or Safari's? What can I do to stop it happening?

• PHP, MySQL - My own version of SALT (I call salty) - Login Issue

  - by Fabio Anselmo

  Ok I wrote my own version of SALT I call it salty lol don't make fun of me.. Anyway the registration part of my script as follows is working 100% correctly. //generate SALTY my own version of SALT and I likes me salt.. lol function rand_string( $length ) { $chars = "ABCDEFGHIJKLMNOPQRSTUWXYZabcdefghijklmnopqrstuwxyz1234567890"; $size = strlen( $chars ); for( $i = 0; $i < $length; $i++ ) { $str .= $chars[ rand( 0, $size - 1 ) ]; } return $str; } $salty = rand_string( 256 ); //generate my extra salty pw $password = crypt('password'); $hash = $password . $salty; $newpass = $hash; //insert the data in the database include ('../../scripts/dbconnect.php'); //Update db record with my salty pw ;) // TESTED WITH AND WITHOUT SALTY //HENCE $password and $newpass mysql_query("UPDATE `Register` SET `Password` = '$password' WHERE `emailinput` = '$email'"); mysql_close($connect); However my LOGIN script is failing. I have it setup to TEST and echo if its login or not. It always returns FAILED. I entered the DB and changed the crypted salty pw to "TEST" and I got a SUCCESS. So my problem is somewhere in this LOGIN script I assume. Now I am not sure how to implement my $Salty in this. But also be advised that even without SALTY (just using crypt to store my pass) - I was still unable to perform a login successfully. And if you're gonna suggest i use blowfish - note that my webhost doesn't have it supported and i don't know how to install it. here's my login script: if (isset($_POST['formsubmitted'])) { include ('../../scripts/dbconnect.php'); $username = mysql_real_escape_string($_POST['username']); $password = crypt(mysql_real_escape_string($_POST['password'])); $qry = "SELECT ID FROM Register WHERE emailinput='$username' AND Password='$password'"; $result = mysql_query($qry); if(mysql_num_rows($result) > 0) { echo 'SUCCESS'; //START SESSION } else { echo 'FAILED'; //YOU ARE NOT LOGGED IN } } So what's wrong with this login? Why isn't it working just using the crypt/storing only crypt? How can i make it work storing both the crypt and randomly generated SALTY :) ? Ty advance

• Insert Registration Data in MySQL using PHP

  - by J M 4

  I may not be asking this in the best way possible but i will try my hardest. Thank you ahead of time for your help: I am creating an enrollment website which allows an individual OR manager to enroll for medical testing services for professional athletes. I will NOT be using the site as a query DB which anybody can view information stored within the database. The information is instead simply stored, and passed along in a CSV format to our network provider so they can use as needed after the fact. There are two possible scenarios: Scenario 1 - Individual Enrollment If an individual athlete chooses to enroll him/herself, they enter their personal information, submit their payment information (credit/bank account) for processing, and their information is stored in an online database as Athlete1. Scenario 2 - Manager Enrollment If a manager chooses to enroll several athletes he manages/ promotes for, he enters his personal information, then enters the personal information for each athlete he wishes to pay for (name, address, ssn, dob, etc), then submits payment information for ALL athletes he is enrolling. This number can range from 1 single athlete, up to 20 athletes per single enrollment (he can return and complete a follow up enrollment for additional athletes). Initially, I was building the database to house ALL information regardless of enrollment type in a single table which housed over 400 columns (think 20 athletes with over 10 fields per athlete such as name, dob, ssn, etc). Now that I think about it more, I believe create multiple tables (manager(s), athlete(s)) may be a better idea here but still not quite sure how to go about it for the following very important reasons: Issue 1 If I list the manager as the parent table, I am afraid the individual enrolling athlete will not show up in the primary table and will not be included in the overall registration file which needs to be sent on to the network providers. Issue 2 All athletes being enrolled by a manager are being stored in SESSION as F1FirstName, F2FirstName where F1 and F2 relate to the id of the fighter. I am not sure technically speaking how to store multiple pieces of information within the same table under separate rows using PHP. For example, all athleteswill have a first name. The very basic theory of what i am trying to do is: If number_of_athletes 1, store F1FirstName in row 1, column 1 of Table "Athletes"; store F1LastName in row 1, column 2 of Table "Athletes"; store F2FirstName in row 2, column 1 of Table "Athletes"; store F2LastName in row 2, column 2 of table "Athletes"; Does this make sense? I know this question is very long and probably difficult so i appreciate the guidance.

• Play! Framework - Can my view template be localised when rendering it as an AsyncResult?

  - by avik

  I've recently started using the Play! framework (v2.0.4) for writing a Java web application. In the majority of my controllers I'm following the paradigm of suspending the HTTP request until the promise of a web service response has been fulfilled. Once the promise has been fulfilled, I return an AsyncResult. This is what most of my actions look like (with a bunch of code omitted): public static Result myActionMethod() { Promise<MyWSResponse> wsResponse; // Perform a web service call that will return the promise of a MyWSResponse... return async(wsResponse.map(new Function<MyWSResponse, Result>() { @Override public Result apply(MyWSResponse response) { // Validate response... return ok(myScalaViewTemplate.render(response.data())); } })); } I'm now trying to internationalise my app, but hit the following error when I try to render a template from an async method: [error] play - Waiting for a promise, but got an error: There is no HTTP Context available from here. java.lang.RuntimeException: There is no HTTP Context available from here. at play.mvc.Http$Context.current(Http.java:27) ~[play_2.9.1.jar:2.0.4] at play.mvc.Http$Context$Implicit.lang(Http.java:124) ~[play_2.9.1.jar:2.0.4] at play.i18n.Messages.get(Messages.java:38) ~[play_2.9.1.jar:2.0.4] at views.html.myScalaViewTemplate$.apply(myScalaViewTemplate.template.scala:40) ~[classes/:na] at views.html.myScalaViewTemplate$.render(myScalaViewTemplate.template.scala:87) ~[classes/:na] at views.html.myScalaViewTemplate.render(myScalaViewTemplate.template.scala) ~[classes/:na] In short, where I've got a message bundle lookup in my view template, some Play! code is attempting to access the original HTTP request and retrieve the accept-languages header, in order to know which message bundle to use. But it seems that the HTTP request is inaccessible from the async method. I can see a couple of (unsatisfactory) ways to work around this: Go back to the 'one thread per request' paradigm and have threads block waiting for responses. Figure out which language to use at Controller level, and feed that choice into my template. I also suspect this might not be an issue on trunk. I know that there is a similar issue in 2.0.4 with regards to not being able to access or modify the Session object which has recently been fixed. However I'm stuck on 2.0.4 for the time being, so is there a better way that I can resolve this problem?

• How to write my own global lock / unlock functions for PostgreSQL

  - by rafalmag

  I have postgresql (in perlu) function getTravelTime(integer, timestamp), which tries to select data for specified ID and timestamp. If there are no data or if data is old, it downloads them from external server (downloading time ~300ms). Multiple process use this database and this function. There is an error when two process do not find data and download them and try to do an insert to travel_time table (id and timestamp pair have to be unique). I thought about locks. Locking whole table would block all processes and allow only one to proceed. I need to lock only on id and timestamp. pg_advisory_lock seems to lock only in "current session". But my processes uses their own sessions. I tried to write my own lock/unlock functions. Am I doing it right? I use active waiting, how can I omit this? Maybe there is a way to use pg_advisory_lock() as global lock? My code: CREATE TABLE travel_time_locks ( id_key integer NOT NULL, time_key timestamp without time zone NOT NULL, UNIQUE (id_key, time_key) ); ------------ -- Function: mylock(integer, timestamp) DROP FUNCTION IF EXISTS mylock(integer, timestamp) CASCADE; -- Usage: SELECT mylock(1, '2010-03-28T19:45'); -- function tries to do a global lock similar to pg_advisory_lock(key, key) CREATE OR REPLACE FUNCTION mylock(id_input integer, time_input timestamp) RETURNS void AS $BODY$ DECLARE rows int; BEGIN LOOP BEGIN -- active waiting here !!!! :( INSERT INTO travel_time_locks (id_key, time_key) VALUES (id_input, time_input); EXCEPTION WHEN unique_violation THEN CONTINUE; END; EXIT; END LOOP; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE COST 1; ------------ -- Function: myunlock(integer, timestamp) DROP FUNCTION IF EXISTS myunlock(integer, timestamp) CASCADE; -- Usage: SELECT myunlock(1, '2010-03-28T19:45'); -- function tries to do a global unlock similar to pg_advisory_unlock(key, key) CREATE OR REPLACE FUNCTION myunlock(id_input integer, time_input timestamp) RETURNS integer AS $BODY$ DECLARE BEGIN DELETE FROM ONLY travel_time_locks WHERE id_key=id_input AND time_key=time_input; RETURN 1; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE COST 1;

• posting php code using jquery .html()

  - by Emmanuel Imwene

  simple query,but it's giving me a headache, i need a division to be updated with a changed session variable each time a user clicks on a name,i figured i'd use .html() using jquery to update the division, i don't know if you can do this, but here goes: $("#inner").html('<?php session_start(); if(file_exists($_SESSION['full'])||file_exists($_SESSION['str'])){ if(file_exists($_SESSION['full'])) { $full=$_SESSION['full']; $handlle = fopen($full, "r"); $contents = fread($handlle, filesize($full)); fclose($handlle); echo $contents; echo '<script type="text/javascript" src="jquery-1.8.0.min (1).js">'; echo '</script>'; echo '<script type="text/javascript">'; echo 'function loadLog(){ var oldscrollHeight = $("#inner").attr("scrollHeight") - 20; $.ajax({ url: \''.$_SESSION['full'].'\', cache: false, success: function(html){ $("#inner").html(html); //Insert chat log into the #chatbox div var newscrollHeight = $("#inner").attr("scrollHeight") - 20; if(newscrollHeight > oldscrollHeight){ $("#inner").animate({ scrollTop: newscrollHeight }, \'normal\'); //Autoscroll to bottom of div } }, }); } setInterval (loadLog, 2500);'; echo '</script>'; } else { $str=$_SESSION['str']; if(file_exists($str)) { $handle = fopen($str, 'r'); $contents = fread($handle, filesize($str)); fclose($handle); echo $contents; $full=$_SESSION['full']; $handlle = fopen($full, "r"); $contents = fread($handlle, filesize($full)); fclose($handlle); echo $contents; echo '<script type="text/javascript" src="jquery-1.8.0.min (1).js">'; echo '</script>'; echo '<script type="text/javascript">'; echo 'function loadLog(){ var oldscrollHeight = $("#inner").attr("scrollHeight") - 20; $.ajax({ url: \''.$_SESSION['str'].'\', cache: false, success: function(html){ $("#inner").html(html); //Insert chat log into the #chatbox div var newscrollHeight = $("#inner").attr("scrollHeight") - 20; if(newscrollHeight > oldscrollHeight){ $("#inner").animate({ scrollTop: newscrollHeight }, \'normal\'); //Autoscroll to bottom of div } }, }); } setInterval (loadLog, 2500);'; echo '</script>'; } } } ?>'); is that legal, if not, how would i accomplish this?

• Validate dependent model validation and show error message.

  - by piemesons

  Just taking a simple example. We have a question on stackoverflow and while posting a question we want to validate title_of_question, description_of_question that they should be present. Now we have a another model tag having habtm relationshio with question model. How to validate that while saving the question. Means question must have some tags. here the code:-- Models:-- class Question < ActiveRecord::Base belongs_to :user has_and_belongs_to_many :tags has_many :comments, :as => :commentable has_many :answers, :dependent => :destroy validates_presence_of :title, :content, :user_id end class Tag < ActiveRecord::Base has_and_belongs_to_many :questions validates_presence_of :tag end Form for entering question and tag <div class="form"> <% form_for :question ,@question, :url => {:action => "create" } do |f| %> <fieldset> <%= f.error_messages %> <legend>Post a question</legend> <div> <%= f.label :title %>: <%= f.text_field :title, :size => 100 %> </div> <div> <%= f.label :content ,'Question' %>: <%= f.text_area :content, :rows => 10, :cols => 100 %> </div> <div> <%= label_tag 'tags' %>: <%= text_field_tag 'tag' ,'',:size=> 60 %> add multiple tag using comma </div> <div> <%= submit_tag "Post question" %> </div> </fieldset> <% end %> </div> From Controller.. (Right now question will be saved without validating tag) def create @question = Question.new(params[:question]) @question.user_id=session[:user_id] if @question.save flash[:notice] = "Question has been posted." redirect_to question_index_path else render :action => "new" end end questions_tags table has been created. One approach is creating a virtual column using attribute accessors. another approach is validate associated. right now assuming new tags can be created.(but not duplicate).

• Crystal Reports : How to add an external assembly class?

  - by Sunil

  I am using VS2010, CrystalReport13 & MVC3. My problem is unable to add an external assembly in Crystal Report using "Database Expert" Option. I have a class named WeeklyReportModel in an external assembly. In my web project, data retrieving from DB as IEnumerable collection of WeeklyReportModel. I tried ProjectData - .NetObjects in Crystal Report for adding the WeeklyReportModel. But this external assembly is not showing under ".NetObjects". Then I tried other option as Create New Connection - ADO.Net – Make New Connection and pointed this External Assembly. It has been added under Ado.Net node, but while expanding displays as "...no items found..." Totally frustrated. Please help. External Assembly Class: namespace SMS.Domain { public class WeeklyReportModel { public int StoreId { get; set; } public string StoreName{ get; set; } public decimal Saturday { get; set; } public decimal Sunday { get; set; } public decimal Monday { get; set; } public decimal Tuesday { get; set; } public decimal Wednesday { get; set; } public decimal Thurday { get; set; } public decimal Friday { get; set; } public decimal Average { get; set; } public string DateRange { get; set; } } } In Controller-action[Data retrieving as Collection Of WeeklyReportModel] namespace SMS.UI.Controllers { public class ReportController : Controller { public ActionResult StoreWeeklyReport(string id) { DateTime weekStart, weekClose; string[] dateArray = id.Split('_'); weekStart = Convert.ToDateTime(dateArray[0].ToString()); weekClose = Convert.ToDateTime(dateArray[1].ToString()); SMS.Infrastructure.Report.AuditReport weeklyReport = new SMS.Infrastructure.Report.AuditReport(); IEnumerable<SMS.Domain.WeeklyReportModel> weeklyRpt = weeklyReport.ReportByStore().WeeklyReport(weekStart, weekClose); Session["WeeklyData"] = weeklyRpt; Response.Redirect("~/Reports/Weekly/StoreWeekly.aspx"); return View(); } } } Thanks in advance.

• Dynamic loaded libraries and shared global symbols

  - by phlipsy

  Since I observed some strange behavior of global variables in my dynamically loaded libraries, I wrote the following test. At first we need a statically linked library: The header test.hpp #ifndef __BASE_HPP #define __BASE_HPP #include <iostream> class test { private: int value; public: test(int value) : value(value) { std::cout << "test::test(int) : value = " << value << std::endl; } ~test() { std::cout << "test::~test() : value = " << value << std::endl; } int get_value() const { return value; } void set_value(int new_value) { value = new_value; } }; extern test global_test; #endif // __BASE_HPP and the source test.cpp #include "base.hpp" test global_test = test(1); Then I wrote a dynamically loaded library: library.cpp #include "base.hpp" extern "C" { test* get_global_test() { return &global_test; } } and a client program loading this library: client.cpp #include <iostream> #include <dlfcn.h> #include "base.hpp" typedef test* get_global_test_t(); int main() { global_test.set_value(2); // global_test from libbase.a std::cout << "client: " << global_test.get_value() << std::endl; void* handle = dlopen("./liblibrary.so", RTLD_LAZY); if (handle == NULL) { std::cout << dlerror() << std::endl; return 1; } get_global_test_t* get_global_test = NULL; void* func = dlsym(handle, "get_global_test"); if (func == NULL) { std::cout << dlerror() << std::endl; return 1; } else get_global_test = reinterpret_cast<get_global_test_t*>(func); test* t = get_global_test(); // global_test from liblibrary.so std::cout << "liblibrary.so: " << t->get_value() << std::endl; std::cout << "client: " << global_test.get_value() << std::endl; dlclose(handle); return 0; } Now I compile the statically loaded library with g++ -Wall -g -c base.cpp ar rcs libbase.a base.o the dynamically loaded library g++ -Wall -g -fPIC -shared library.cpp libbase.a -o liblibrary.so and the client g++ -Wall -g -ldl client.cpp libbase.a -o client Now I observe: The client and the dynamically loaded library possess a different version of the variable global_test. But in my project I'm using cmake. The build script looks like this: CMAKE_MINIMUM_REQUIRED(VERSION 2.6) PROJECT(globaltest) ADD_LIBRARY(base STATIC base.cpp) ADD_LIBRARY(library MODULE library.cpp) TARGET_LINK_LIBRARIES(library base) ADD_EXECUTABLE(client client.cpp) TARGET_LINK_LIBRARIES(client base dl) analyzing the created makefiles I found that cmake builds the client with g++ -Wall -g -ldl -rdynamic client.cpp libbase.a -o client This ends up in a slightly different but fatal behavior: The global_test of the client and the dynamically loaded library are the same but will be destroyed two times at the end of the program. Am I using cmake in a wrong way? Is it possible that the client and the dynamically loaded library use the same global_test but without this double destruction problem?
