• Eclipse CDT: cannot debug or terminate application

  - by Paul Lammertsma

  I have Eclipse set up fairly nicely to run the G++ compiler through Cygwin. Even the character encoding is set up correctly! There still seems to be something wrong with my configuration: I can't debug. The pause button in the debug view is simply disabled, and no threads appear in my application tree. It seems that gdb is simply not communicating with Eclipse. Presently, I have the debug settings as follows: Debugger: "Cygwin gdb Debugger" GDB debugger: gdb GDB command file: .gdbinit Protocol: Default I should mention here that I have no idea what .gdbinit does; in my project it is merely an empty file. What is wrong with my configuration? Debugging When attempting to terminate the application in debug mode, Eclipse displays the following error: Target request failed: failed to interrupt. I can't kill the process, either; I have to kill its parent gdb.exe, which in turn kills my application. Running When running it normally, a bunch of kill.exes are called, doing nothing, while Eclipse displays the following error: Terminate failed. I can kill FaceDetector.exe from the task manager. Process Explorer This is what it looks like in Process Explorer (debugging left, running right):

• Show cue banner for wpf ComboBox with grouping

  - by Adam Duston

  I have a ComboBox in my WPF form: <ComboBox Margin="75,0,15,102" Name="videoFormatCombo" Height="23" VerticalAlignment="Bottom" DataContext="{StaticResource GroupedVideoFormats}" ItemsSource="{Binding}" ItemTemplate="{StaticResource VideoFormatTemplate}"> <ComboBox.GroupStyle> <GroupStyle HeaderTemplate="{StaticResource GroupHeader}"/> </ComboBox.GroupStyle> </ComboBox> As you might be able to guess, GroupedVideoFormats is a CollectionViewSource with grouping. I need to get a cue banner to display for this ComboBox. I've attempted the solution that is (very verbosely) outlined in this blog post, but it will not work for a ComboBox with grouped data. The two solutions outlined in superfluousprefixhttp://stackoverflow.com/questions/2548757/how-can-the-blank-space-in-a-c-combobox-be-filled-as-a-hint-for-the-user are for Windows Forms ComboBoxes only, and won't work with WPF. If it would help to see all the original source, this particular form is on github: superfluousprefixhttp://github.com/8planes/mirovideoconverter/blob/master/MSWindows/Windows/FileSelect.xaml . It's an open-source project, so the entire project is on github: superfluousprefixhttp://github.com/8planes/mirovideoconverter/tree/master/MSWindows . Thank you for any advice! Adam P.S. stackoverflow wouldn't let me make more than one anchor tag in my post, hence the long urls with the superfluous prefix. Sorry!

• Merging k sorted linked lists - analysis

  - by Kotti

  Hi! I am thinking about different solutions for one problem. Assume we have K sorted linked lists and we are merging them into one. All these lists together have N elements. The well known solution is to use priority queue and pop / push first elements from every lists and I can understand why it takes O(N log K) time. But let's take a look at another approach. Suppose we have some MERGE_LISTS(LIST1, LIST2) procedure, that merges two sorted lists and it would take O(T1 + T2) time, where T1 and T2 stand for LIST1 and LIST2 sizes. What we do now generally means pairing these lists and merging them pair-by-pair (if the number is odd, last list, for example, could be ignored at first steps). This generally means we have to make the following "tree" of merge operations: N1, N2, N3... stand for LIST1, LIST2, LIST3 sizes O(N1 + N2) + O(N3 + N4) + O(N5 + N6) + ... O(N1 + N2 + N3 + N4) + O(N5 + N6 + N7 + N8) + ... O(N1 + N2 + N3 + N4 + .... + NK) It looks obvious that there will be log(K) of these rows, each of them implementing O(N) operations, so time for MERGE(LIST1, LIST2, ... , LISTK) operation would actually equal O(N log K). My friend told me (two days ago) it would take O(K N) time. So, the question is - did I f%ck up somewhere or is he actually wrong about this? And if I am right, why doesn't this 'divide&conquer' approach can't be used instead of priority queue approach?

• Multiple Ruby versions on one webserver?

  - by Legion

  The Ideal Using rvm, it would be awesome to be able to have multiple Rubies on one webserver, and through some sort of server configuration, be able to assign Ruby versions to different Rails/Sinatra/etc apps on a per-project basis. I am aware, from rvm's documentation, that Passenger only works with one Ruby at a time. :( The Compromise Failing that, it would be nice to at least be able to concoct a way to be able to assign projects to a Ruby 1.8 or a Ruby 1.9 interpreter. I've read that using Nginx as a reverse proxy allows running Apache and Nginx on the same box. Would it then be possible to have Apache+Passenger using one Ruby, and Nginx+Passenger using a different one? Maybe use something other than Passenger with Nginx? Am I Barking Up the Wrong Tree? Am I missing a good solution to this issue? Am I walking into a nightmare configuration situation? Is what I want even viable, or is it necessary to run another box to run a separate Ruby version?

• What is the correct way to handle object which is instance of class in apache.xerces?

  - by Roman

  Preface: I'm working on docx parser for java. docx format is based on xml. When I read document its parts are being unmarshalled (with JAXB). And I get a tree of certain elements based on xml markup. Almost problem: But some elements (which are at very deep xml level) returned not as certain class from docx spec (i.e. CTStyle, CTDrawing, CTInline etc) but as Object. Those objects are indeed instances of xerces classes, e.g. ElementNSImpl. Problem: How should I handle these objects. The simplest approach is: CTGraphicData gData = getGraphicData (); Object obj = gData.getAny().get(0); ElementNSImpl element = (ElementNSImpl)obj; But it doesn't seem to be a good solution. I've never worked with xerces directly. What is the better way to do this casting? (If anyone also give me a tip about right way to iterate through nodes it would be great).

  - by user187532

  Hello friends, I am trying to implement 'scrollview' effect in 'Tabbar' which has 'TabItems'. I found that the good example is from 'facebook' open source 'TTCatlog' project 'Tabs' section.

Could someone please help what's wrong there and how do i get rid of this issue and continue working with it?

• NSOutlineView/NSTreeController - calculate sum of column

  - by matei

  I have a NSOutlineView bound to a NSTreeController. My data items are a custom class , let's call them "Row", and suppose a Row contains a "name" and a numeric field called "number" . All these "Rows" are found in let's say a "RowContainer" which has a "rows" mutable array holding the parent (level 0) rows. Each row also has a "children" NSMutableArray member which holds it's children. I have this working, and I want to display under the outlineview a textfield with the sum of all the "number" values of the rows. I bound this textfield to a "total" property of the "RowContainer". Now the problem is how or from where to trigger the recalculation of the "total" property, since this involves a recursive walk on the tree of rows, and I always get a "Collection was mutated while being enumerated" error. I've tried making a method "recalculateTotal", and calling it from the "setNumber" method of the "Row" class , but same error occurs. If I put the recalculation logic in the "total" getter, I can't trigger it to do the math. I'm sure the solution is simple but I can't see it

• Display a input type=file over another input type=file

  - by Kevin Sedgley

  WARNING: Lengthy description coming up! I have written an uploader based upon APC progress uploader for PHP. This works fine and dandy, but the script as a whole (apc etc) is intended to be used only for those with Javascript. To achieve this, I have searched for any input type=file, and replaced these with an absolutely positioned form that appears over the original area where the old file input area was. The reasons for this are so the new uploader can submit to a hidden in page IFrame has to be in a seperate <form> in order to submit to the APC reciever to display the progress upload bar. allows it to be used within any form with an input type=file throughout the site I have used JQuery to do this, with the following code: Original HTML form code: <div><input type="file" name="media" id="media" /></div> Find position of div block code: // get the parent div, and properties thereof parentDiv = $(this).closest('div'); w = $(parentDiv).width(); h = $(parentDiv).height(); loc = $(parentDiv).offset(); Locate new block over old block: $('#_sender').appendTo('body').css({left:loc.left,top:loc.top,position:'absolute',zIndex:400,height:h,width:w}).show(); This works fine, and shows over the old block OK. The problem: When other elements in the DOM before or above it change (in this case a "tree view" selector is pushing the old block down) the new upload form gets moved over other elements. Is there a JQuery (or JS) method for changing this upon DOM change? Some kind of .onchange for the page?! Or an .onmove for the original block? Thanks in advance you lovely people Before DOM change: . After: .

• Jquery ajaxStart doesnt get triggered

  - by gnomixa

  This code $("#loading").ajaxStart(function() { alert("start"); $(this).show(); }); in my mark-up <div style="text-align:center;"><img id="loading" src="../images/common/loading.gif" alt="" /></div> Here is the full ajax request: $.ajax({ type: "POST", url: "http://localhost/WebServices/Service.asmx/GetResults", data: jsonText, contentType: "application/json; charset=utf-8", dataType: "json", success: function(response) { var results = (typeof response.d) == 'string' ? eval('(' + response.d + ')') : response.d; PopulateTree(results); }, error: function(xhr, status, error) { var msg = JSON.parse(xhr.responseText); alert(msg.Message); } }); $("#loading").ajaxStart(function() { alert("start"); $(this).show(); }); $("#loading").ajaxStop(function() { alert("stop"); $(this).hide(); $("#st-tree-container").show(); }); never fires alert "start" even though the gif is shown to rotate. AjaxStop gets triggered as expected. Any ideas why?

• css, unordered list not displaying icon in right place...

  - by Ronedog

  I'm really frustrated with this one. A few weeks ago I got it working in both firefox and ie just fine. Went back today to do some testing and found a problem with the display in firefox and I've been searching the code but can't find anything. I could use a few tips from anyone willing, I'm sure I'm looking at the wrong things. I upgraded my firefox version but I imagine my code is broke, not firefox. I'm assuming the problem is somewhere in my css file, but I'm not sure. Here's what I've confirmed so far. There don't seem to be conflicts in other css files with < ul 's or < li 's that may be overriding settings. The other confirmation is that This works fine in Internet Explorer...therefore I must be an idiot, because its usually been the other way around (working in FF, but failing in IE). Here's How it looks in IE (Notice the position of the folder icon right next to the text): Here's how it looks in FF (Notice the folder icon is not being pushed down with its corresponding text). Here's the Unordered List: <ul id="nav"> <li><a>Utah</a></li> <ul> <li><a>ParkCity</a> <ul> <li><a>Com1</a></li> <ul> <li class="folder_closed"><a>Timber</a></li> <div>SQUARE CONTAINER IS INSIDE THIS DIV</div> </ul> </ul> </ul> </ul> Here's the CSS that is used for the whole menu: /* MENU NAVIGATION (<UL><LI> LISTS ****************************************/ ul#nav{ /* This handles the main root <ul> */ margin-left:0; margin-right:0; padding-left:0px; text-indent:15px; } ul#nav div{ overflow: hidden; } #nav li>a:hover { cursor: pointer; } #nav li > ul{ /* This will hide any element with an id of "nav" and an "li" that has a direct child that is a "ul" */ display:none; margin-left:0px; margin-right:0px; padding-left:15px; padding-right:0px; text-indent:15px; } #nav li { list-style-type:none; list-style-image: none; } #nav > li{ vertical-align: top; left:0px; text-align:left; clear: both; margin:0px; margin-right:0px; padding-right:0px; } .menu_parent{ background-image: url(../images/maximize.png); background-repeat: no-repeat; background-position: 0px 1px; position:relative; } .menu_parent_minimized{ background-image: url(../images/minimize.png); background-repeat: no-repeat; background-position: 0px 1px; position:relative; } .folder_closed{ position:relative; background-image: url(../images/folder_closed12x14.png); background-repeat: no-repeat; background-position: 0px -2px; } .folder_open{ position:relative; background-image: url(../images/folder_open12x14.png); background-repeat: no-repeat; background-position: 0px -2px; } </ul>

• Trying to use Rhino, getEngineByName("JavaScript") returns null in OpenJDK 7

  - by Yuval

  When I run the following piece of code, the engine variable is set to null when I'm using OepnJDK 7 (java-7-openjdk-i386). import javax.script.ScriptEngine; import javax.script.ScriptEngineManager; import javax.script.ScriptException; public class TestRhino { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub ScriptEngineManager factory = new ScriptEngineManager(); ScriptEngine engine = factory.getEngineByName("JavaScript"); try { System.out.println(engine.eval("1+1")); } catch (ScriptException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } It runs fine with java-6-openjdk and Oracle's jre1.7.0. Any idea why? I'm using Ubuntu 11.10. All JVMs are installed under /usr/lib/jvm. I noticed OpenJDK 7 has a different directory structure. Perhaps something is not installed right? $ locate rhino.jar /usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar /usr/lib/jvm/java-7-openjdk-common/jre/lib/rhino.jar /usr/lib/jvm/java-7-openjdk-i386/jre/lib/rhino.jar Edit Since ScriptEngineManager uses a ServiceProvider to find the available script engines, I snooped around resources.jar's META-INF/services. I noticed that in OpenJDK 6, resources.jar has a META-INF/services/javax.script.ScriptEngineFactory entry which is missing from OpenJDK 7. Any idea why? I suspect this is a bug? Here is the contents of that entry (from OpenJDK 6): #script engines supported com.sun.script.javascript.RhinoScriptEngineFactory #javascript Another edit Apparently, according to this thread, the code simply isn't there, perhaps because of merging issues between Sun and Mozilla code. I still don't understand why it was present in OpenJDK 6 and not 7. The class com.sun.script.javascript.RhinoScriptEngineFactory exists in 6's rt.jar but not in 7's. If it was not meant to be included, why is there a OpenJDK 7 rhino.jar then; and why is the source still in the OpenJDK source tree (here)?

• Consistent Equals() results, but inconsistent TreeMap.containsKey() result

  - by smessing

  I have the following object Node: private class Node implements Comparable<Node>(){ private String guid(); ... public boolean equals(Node o){ return (this == o); } public int hashCode(){ return guid.hashCode(); } ... } And I use it in the following TreeMap: TreeMap<Node, TreeSet<Edge>> nodes = new TreeMap<Node, TreeSet<Edge>>(); Now, the tree map is used in a class called Graph to store nodes currently in the graph, along with a set of their edges (from the class Edge). My problem is when I try to execute: public containsNode(n){ for (Node x : nodes.keySet()) { System.out.println("HASH CODE: "); System.out.print(x.hashCode() == n.hashCode()); System.out.println("EQUALS: "); System.out.print(x.equals(n)); System.out.println("CONTAINS: "); System.out.print(nodes.containsKey(n)); System.out.println("N: " + n); System.out.println("X: " + x); } } I sometimes get the following: HASHCODE: true EQUALS: true CONTAINS: false N: foo X: foo Anyone have an idea as to what I'm doing wrong? I'm still new to all this, so I apologize in advance if I'm overlooking something simple (I know hashCode() doesn't really matter for TreeMap, but I figured I'd include it).

• Xpath fails if an element has a a xmlns attribute

  - by Callum Lamb

  Im trying to use xml to parse a .COLLADA file. The problem is I can't seem to use xpath() to access elements if the root tag has a xmlns attribute. For example this works: $string = <<<TEST <?xml version="1.0" encoding="utf-8"?> <COLLADA version="1.4.1"> <library_materials> <material id="Material" name="Material"> <instance_effect url="#Material-effect"/> </material> <material id="Material2" name="Material"> <instance_effect url="#Material-effect2"/> </material> </library_materials> </COLLADA> TEST; $lol = new SimpleXMLElement($string); print_r($lol->library_materials->xpath("material[@id='Material2']")); But this doesn't: $string = <<<TEST <?xml version="1.0" encoding="utf-8"?> <COLLADA xmlns="http://www.collada.org/2005/11/COLLADASchema" version="1.4.1"> <library_materials> <material id="Material" name="Material"> <instance_effect url="#Material-effect"/> </material> <material id="Material2" name="Material"> <instance_effect url="#Material-effect2"/> </material> </library_materials> </COLLADA> TEST; $lol = new SimpleXMLElement($string); print_r($lol->library_materials->xpath("material[@id='Material2']")); How does the xmlns suddenly make the xml tree unusable? I thought it just defined the namespace so you could tell it apart from other identical tags in other namespaces. What am I missing?

• SharePoint Feature suggestion

  - by barathan

  I have written a feature(Site scoped) that adds custom menu items to the New Menu and EditControlBlock of document library. These menu items should show up only when the user has add and edit permissions for that document library. If he selected the menu, url is redirected to my webpart. Webpart is deployed in site collection. To do this i have two way. I mentioned in as case 1 & case 2. But in the both cases i failed to fulfill my requirement Below are the sample entries in Feature and Element manifest file I am passing the current location to sourceurl in order to get the folder url <?xml version="1.0" encoding="utf-8" ?> <Feature Id="59bba8e7-0cfc-46e3-9285-4597f8085e76" Title="My Custom Menus" Scope="Site" xmlns="http://schemas.microsoft.com/sharepoint/"> <ElementManifests> <ElementManifest Location="Elements.xml" /> </ElementManifests></Feature> Case 1: <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <CustomAction Id="EditMenu1" RegistrationType="FileType" RegistrationId="txt" Location="EditControlBlock" Sequence="106" ImageUrl="/_layouts/images/PPT16.GIF" Title="My Edit Menu" Rights="AddListItems,EditListItems"> <UrlAction Url="javascript:var surl='{SiteUrl}'; window.location='/test/mypage.aspx?siteurl='+surl+'&amp;itemurl={ItemUrl}&amp;itemid={ItemId}&amp;listid={ListId}&amp;Source='+window.location" /> </CustomAction> <CustomAction Id="NewMenu1" GroupId="NewMenu" RegistrationType="List" RegistrationId="101" Location="Microsoft.SharePoint.StandardMenu" Sequence="1002" ImageUrl ="/_layouts/images/DOC32.GIF" Title="My New Menu" Rights="AddListItems,EditListItems"> <UrlAction Url="javascript:var surl='{SiteUrl}'; window.location='/test/mypage.aspx?siteurl='+surl+'&amp;listid={ListId}&amp;Source='+window.location" /> </CustomAction> </Elements> If i use the above code, it was not redirected to site collection instead of it is redirecting to rootsite. Is there is any way to get the site collection variable. To overcome this issue i used the following code: Case 2: <?xml version="1.0" encoding="utf-8" ?> <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <CustomAction Id="EditMenu1" RegistrationType="FileType" RegistrationId="txt" Location="EditControlBlock" Sequence="106" ImageUrl="/_layouts/images/PPT16.GIF" Title="My Edit Menu" Rights="AddListItems,EditListItems"> <UrlAction Url="~sitecollection/test/mypage.aspx?siteurl={SiteUrl}&amp;itemurl={ItemUrl}&amp;itemid={ItemId}&amp;listid={ListId}&amp;Source=/" /> </CustomAction> <CustomAction Id="NewMenu1" GroupId="NewMenu" RegistrationType="List" RegistrationId="101" Location="Microsoft.SharePoint.StandardMenu" Sequence="1002" ImageUrl ="/_layouts/images/DOC32.GIF" Title="My New Menu" Rights="AddListItems,EditListItems"> <UrlAction Url="~sitecollection/test/mypage.aspx?siteurl={SiteUrl}&amp;listid={ListId}&amp;Source=/" /> </CustomAction> </Elements> But in this case, it is correctly redirected to the site collection. But it fails to get the folder url because current location can't pass through in this case. while creating new document. Could you please suggest me either how to get the site collection url in the case 1 or how to pass the current location to the sourceul in case 2

• Finding the last focused element

  - by Joshua Cody

  I'm looking to determine which element had the last focus in a series of inputs, that are added dynamically by the user. This code can only get the inputs that are available on page load: $('input.item').focus(function(){ $(this).siblings('ul').slideDown(); }); And this code sees all elements that have ever had focus: $('input.item').live('focus', function(){ $(this).siblings('ul').slideDown(); }); The HTML structure is this: <ul> <li><input class="item" name="goals[]"> <ul> <li>long list here</li> <li>long list here</li> <li>long list here</li> </ul></li> </ul> <a href="#" id="add">Add another</a> On page load, a single input loads. Then with each add another, a new copy of the top unordered list's contents are made and appended, and the new input gets focus. When each gets focus, I'd like to show the list beneath it. But I don't seem to be able to "watch for the most recently focused element, which exists now or in the future." To clarify: I'm not looking for the last occurrence of an element in the DOM tree. I'm looking to find the element that currently has focus, even if said element is not present upon original page load. So in the above image, if I were to focus on the second element, the list of words should appear under the second element. My focus is currently on the last element, so the words are displayed there. Do I have some sort of fundamental assumption wrong?

• MySQL nested set hierarchy with foreign table

  - by Björn

  Hi! I'm using a nested set in a MySQL table to describe a hierarchy of categories, and an additional table describing products. Category table; id name left right Products table; id categoryId name How can I retrieve the full path, containing all parent categories, of a product? I.e.: RootCategory > SubCategory 1 > SubCategory 2 > ... > SubCategory n > Product Say for example that I want to list all products from SubCategory1 and it's sub categories, and with each given Product I want the full tree path to that product - is this possible? This is as far as I've got - but the structure is not quite right... select parent.`name` as name, parent.`id` as id, group_concat(parent.`name` separator '/') as path from categories as node, categories as parent, (select inode.`id` as id, inode.`name` as name from categories as inode, categories as iparent where inode.`lft` between iparent.`lft` and iparent.`rgt` and iparent.`id`=4 /* The category from which to list products */ order by inode.`lft`) as sub where node.`lft` between parent.`lft` and parent.`rgt` and node.`id`=sub.`id` group by sub.`id` order by node.`lft`

• beautifulsoup: find the n-th element's sibling

  - by deostroll

  I have a complex html DOM tree of the following nature: <table> ... <tr> <td> ... </td> <td> <table> <tr> <td> <!-- inner most table --> <table> ... </table> <h2>This is hell!</h2> <td> </tr> </table> </td> </tr> </table> I have some logic to find out the inner most table. But after having found it, I need to get the next sibling element (h2). Is there anyway you can do this?

• Partial Evaluation of ConstantExpression in ExpressionTreeVisitor

  - by Andrew Theken

  Hi all, I am not an Expression Tree master by any stretch of the imagination, what I have is code that looks like this: int external = 10; using(var session = new Session()) { session.Add(new Product { Name = "test1", Price = 20 }); session.Add(new Product {Name = "test", Price = 10}); var product = session.Products.Where(p => p.Price == external).FirstOrDefault(); Assert.Equal(10, product.Price); } Session implements all the IQueryProvider, IQueryable interfaces you'd come to expect from a LINQ Provider. When I execute the query, everything goes to plan until I read the ConstantExpression for "external", at which point, I am at a loss as to how to move forward because: //constant is ConstantExpression for "external" on the right side of the "p.Price == external" expression above. var t = constant.GetType(); //evaluates to class called "<>c__DisplayClass2" - with a member named "external" that has the value 10. The question is basically.. How can I just access the value of the member "external" - is there a way to accomplish this without using reflection? or am I cooked? What am I missing?

• Trying to Use LoadMoreElement in Monotouch.Dialog

  - by user1487581

  I am using Monotouch to write an Ipad app. The app uses tables to browse down through a directory tree and then select a file. I have used Monotouch.Dialog to browse the directories and I set up the directory tables as the app starts.However there are too many files to set up in a table as the app starts and so I want to set up the 'file table' as the file is selected from the lowest level directory table. I am trying to use LoadMoreElement to do this but I cannot make it work or find any examples online. I have coded the 'Elements API Walkthrough' in the Xamarin tutorial at:- http://docs.xamarin.com/ios/tutorials/MonoTouch.Dialog I then add a new section to the code:- _addButton.Clicked += (sender, e) => { ++n; var task = new Task{Name = "task " + n, DueDate = DateTime.Now}; var taskElement = new RootElement (task.Name){ new Section () { new EntryElement (task.Name, "Enter task description", task.Description) }, new Section () { new DateElement ("Due Date", task.DueDate) }, new Section() { new LoadMoreElement("Passive","Active", delegate {MyAction();}) } }; _rootElement [0].Add (taskElement); Where MyAction is:- public void MyAction() { Console.WriteLine ("we have been actioned"); } The problem is that MyAction is triggered and Console.Writeline writes the message but the table stays in the active state and never returns to passive. the documentation says:- Once your code in the NSAction is finished, the UIActivity indicator stops animating and the normal caption is displayed again. What am I missing? Ian

• Loop XML including all its children using xpath and SimpleXMLElement

  - by Andersson

  Im having a big xml tree with a simple structure. All I want to do is get a node by its attribute using xpath and loop the children. param1 - correct language param1 & param3 - correct node by its id and the parents id. (Need to use parent id when multiplie id appears. The id is not declared as id in DTD) public function getSubmenuNodesRe($language, $id1,$id2) { $result = $this->xml->xpath("//*[@language='$language']//*[@id='$id1']//menuitem[@id='$id2']/*"); return $result; } This works well, I get the node Im expecting. I having no problems looping the array returned by the xpath query. But when i try to loop childnodes all attributes are gone and many of the methods also. Except getName(). function printNodeName($node) { echo $node->getName(). " - \"" . $node['id']. "\"<br>"; if($node->children()->getName() == "menuitem") { $s = $node->children(); printNodeName($s); } } $result = $xmlNode->getSubmenuNodesRe($_GET['language'], 'foo','bar'); if ($result) { while(list( , $node) = each($result)) { if ($node->getName() == "menuitem") { printNodeName($node); } } } Why is that? only the name will be printed for the $s. Really need help to solve this one, any assistance is deeply appreciated! Thanks for your time.

• How to recursive rake? -- or suitable alternatives

  - by TerryP

  I want my projects top level Rakefile to build things using rakefiles deeper in the tree; i.e. the top level rakefile says how to build the project (big picture) and the lower level ones build a specific module (local picture). There is of course a shared set of configuration for the minute details of doing that whenever it can be shared between tasks: so it is mostly about keeping the descriptions of what needs building, as close to the sources being built. E.g. /Source/Module/code.foo and cie should be built using the instructions in /Source/Module/Rakefile; and /Rakefile understands the dependencies between modules. I don't care if it uses multiple rake processes (ala recursive make), or just creates separate build environments. Either way it should be self-containable enough to be processed by a queue: so that non-dependent modules could be built simultaneously. The problem is, how the heck do you actually do something like that with Rake!? I haven't been able to find anything meaningful on the Internet, nor in the documentation. I tried creating a new Rake::Application object and setting it up, but whatever methods I try invoking, only exceptions or "Don't know how to build task ':default'" errors get thrown. (Yes, all rakefiles have a :default). Obviously one could just execute 'rake' in a sub directory for a :modulename task, but that would ditch the options given to the top level; e.g. think of $(MAKE) and $(MAKEFLAGS). Anyone have a clue on how to properly do something like a recursive rake?

• How to organize integrity tests and code unit tests?

  - by karlthorwald

  I have several files with code testing code (which uses a "unittest" class). Later I found it would be nice to test database integrity also. I put this into a separate directory tree. (Things like the keys have correct format, parent and child nodes are pointing correctly and such.) I use the same unittest class for the integrity tests. Now I wonder if it makes really sense to keep this separate. To test the integrity of data I often duplicate parts of code that I use to test the code that handles the data. But it is not the same. The code tests use test databases (that get deleted after each test) and the integrity tests connect to the live data and analyze it. The integrity tests I want to call from cron and send an alarm if something happens in the live database. How would you handle that? Are there standards for such a setup? What is your experience? My tendency is to put everything in the same file, which would result in the code tests also being executed by the cron on the production environment.

• Saving complex aggregates using Repository Pattern

  - by Kevin Lawrence

  We have a complex aggregate (sensitive names obfuscated for confidentiality reasons). The root, R, is composed of collections of Ms, As, Cs, Ss. Ms have collections of other low-level details. etc etc R really is an aggregate (no fair suggesting we split it!) We use lazy loading to retrieve the details. No problem there. But we are struggling a little with how to save such a complex aggregate. From the caller's point of view: r = repository.find(id); r.Ps.add(factory.createP()); r.Cs[5].updateX(123); r.Ms.removeAt(5); repository.save(r); Our competing solutions are: Dirty flags Each entity in the aggregate in the aggregate has a dirty flag. The save() method in the repository walks the tree looking for dirty objects and saves them. Deletes and adds are a little trickier - especially with lazy-loading - but doable. Event listener accumulates changes. Repository subscribes a listener to changes and accumulates events. When save is called, the repository grabs all the change events and writes them to the DB. Give up on repository pattern. Implement overloaded save methods to save the parts of the aggregate separately. The original example would become: r = repository.find(id); r.Ps.add(factory.createP()); r.Cs[5].updateX(123); r.Ms.removeAt(5); repository.save(r.Ps); repository.save(r.Cs); repository.save(r.Ms); (or worse) Advice please! What should we do?
