  • Subversion has --record-only for merges, how do I do the same in Git ?

    - by Paul Hammant
    I have a repo where 'master' is going in a certain direction, and a second branch 'foo' is going to be divergent for a couple of commits, then track all subsequent changes to 'master' after that. This is all by choice of course. In Subversion you could do a --record-only merge to mark things as "merge has happened" even though no actual changes were committed. i.e. this change the merge-tracking numbers in properties attached to directories in the target branch. I have had a play with.. git merge --no-commit master .. as something I may be able to tinker with before I do the commit, but it is making a hell of a mess of the target branch for part of the change in question (rename followed by delete). There must be an easier way.. ? Paul

  • Python namespace in between builtins and global?

    - by Paul
    Hello, As I understand it python has the following outermost namespaces: Builtin - This namespace is global across the entire interpreter and all scripts running within an interpreter instance. Globals - This namespace is global across a module, ie across a single file. I am looking for a namespace in between these two, where I can share a few variables declared within the main script to modules called by it. For example, script.py: import Log from Log import foo from foo log = Log() foo() foo.py: def foo(): log.Log('test') # I want this to refer to the callers log object I want to be able to call script.py multiple times and in each case, expose the module level log object to the foo method. Any ideas if this is possible? It won't be too painful to pass down the log object, but I am working with a large chunk of code that has been ported from Javascript. I also understand that this places constraints on the caller of foo to expose its log object. Thanks, Paul

  • How to use NetBeans to debug C++ libraries not compiled with NetBeans?

    - by Paul Gotzel
    Hello, I am using NetBeans 6.8 on Redhat Linux. Does anyone know how to configure NetBeans to debug (step into) libraries not compiled with NetBeans? In my particular case, I'm trying to debug the VTK library which is built using cmake with the Debug flag set. I've written a C++ application that uses the shared libraries from VTK. Any ideas? I'd tried the obvious things like adding the source locations to the project. Note that with gdb I can debug the application and set breakpoints anywhere in VTK. Any help would be appreciated. Thanks, Paul

  • How come (a_method || :other) returns :other only when assigning to a var called a_method?

    - by Paul Annesley
    Given the following method: def some_method :value end The following statements work as I would expect: some_method || :other # => :value x = some_method || :other # => :value But the behaviour of the following statement perplexes me: some_method = some_method || :other # => :other It creates a local variable called some_method as expected, and subsequent calls to some_method return the value of that local variable. But why does it assign :other rather than :value? I understand that it's probably not a smart thing to do, and can see how it might be ambiguous, but I thought the right-hand-side of the assignment should be evaluated prior to the assignment being considered... I've tested this in Ruby 1.8.7 and Ruby 1.9.2 with identical results. Cheers! Paul

  • why is optional chaining required in an if let statement

    - by b-ryan ca
    Why would the Swift compiler expect me to write if let addressNumber = paul.residence?.address?.buildingNumber?.toInt() { } instead of just writing: if let addressNumber = paul.residence.address.buildingNumber.toInt() { } The compiler clearly has the static type information to handle the conditional statement for the first dereference of the optional value and each following value. Why would it not continue to do so for the following statements?

  • How to use JQuery UI datepicker with bgIframe on IE 6

    - by Steve Davies
    I am trying to use the JQuery UI datepicker (latest stable version 1.5.2) on an IE6 website. But I am having the usual problems with combo boxes (selects) on IE6 where they float above other controls. I have tried adding the bgIframe plugin after declaring the datepicker with no luck. My guess is that the .ui-datepicker-div to which I am attaching the bgIframe doesn't exist until the calendar is shown. I am wondering if I can put the .bgIframe() command directly into the datepicker .js file and if so, where? (the similar control by kelvin Luck uses this approach) Current code $(".DateItem").datepicker({ showOn:"button", ... etc ... }); $(".ui-datepicker-div").bgIframe();

  • Android SDK fails to install

    - by Paul Breed
    When I try to install the android SDK it fails to install. My OS is Windows XP I just downloaded and installed Java JDK 1.6 Java -version from the command line returns: http://stackoverflow.com/questions/ask java version "1.6.0_17" Java(TM) SE Runtime Environment (build 1.6.0_17-b04) Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode, sharing) My environment vars have: JAVA_HOME=c:\progra~1\java\jdk1.6.0_11 I downloaded android-sdk-r04-windows.zip I unziped it in V:\AndroidInstall\ When I go to the V:\androindinstall\android-sdk-windows and type "SDK Install.exe" nothing happens... If I go this from graph When I do this from a graphical file viewer I get a quick flash that looks like a command line window and nothing.... When I try to run android list targets from the tool directory I get: Error: Error parsing the sdk. Error: V:\androindinstall\android-sdk-windows\platforms is missing. Error: Unable to parse SDK content. So the basic install setup is not happening. Additional clues: I have a G1 and Android 1.0 was running on this machine. (Almost a year ago) I've updated my G1 to 1.6 so I thought I'd update my SDK before starting new development. When I tried to upgrade it tried and then died as the "directory was in use" So I cleaned out all the android directories, rebooted and redownloaded everythign from scratch. Now it won't run at all. I've clearly got something in an unhappy state, but I've cleaned up all the directories and no remanants seem to be running I've rebooted.... I've missed somethign I just can't figure out what. Paul

  • JScript.NET private variables

    I'm wondering about JScript.NET private variables. Please take a look on the following code: import System; import System.Windows.Forms; import System.Drawing; var jsPDF = function(){ var state = 0; var beginPage = function(){ state = 2; out('beginPage'); } var out = function(text){ if(state == 2){ var st = 3; } MessageBox.Show(text + ' ' + state); } var addHeader = function(){ out('header'); } return { endDocument: function(){ state = 1; addHeader(); out('endDocument'); }, beginDocument: function(){ beginPage(); } } } var j = new jsPDF(); j.beginDocument(); j.endDocument(); Output: beginPage 2 header 2 endDocument 2 if I run the same script in any browser, the output is: beginPage 2 header 1 endDocument 1 Why it is so?? Thanks, Paul.

  • Resolving ambiguous this pointer in C++

    - by Paul Tevis
    I'm trying to derive a new class from an old one. The base class declaration looks like this: class Driver : public Plugin, public CmdObject { protected: Driver(); public: static Driver* GetInstance(); virtual Engine& GetEngine(); public: // Plugin methods... virtual bool InitPlugin (Mgr* pMgr); virtual bool Open(); virtual bool Close(); // CmdObject virtual bool ExecObjCmd(uint16 cmdID, uint16 nbParams, CommandParam *pParams, CmdChannelError& error); Mgr *m_pMgr; protected: Services *m_pServices; Engine m_Engine; }; Its constructor looks like this: Driver::Driver() : YCmdObject("Driver", (CmdObjectType)100, true), m_Engine("MyEngine") { Services *m_pServices = NULL; Mgr *m_pMgr = NULL; } So when I created my derived class, I first tried to simply inherit from the base class: class NewDriver : public Driver and copy the constructor: NewDriver::NewDriver() : CmdObject("NewDriver", (EYCmdObjectType)100, true), m_Engine("MyNewEngine") { Services *m_pServices = NULL; Mgr *m_pMgr = NULL; } The compiler (VisualDSP++ 5.0 from Analog Devices) didn't like this: ".\NewDriver.cpp", line 10: cc0293: error: indirect nonvirtual base class is not allowed CmdObject("NewDriver", (EYCmdObjectType)100, true), That made sense, so I decided to directly inherit from Plugin and CmdObject. To avoid multiple inheritance ambiguity problems (so I thought), I used virtual inheritance: class NewDriver : public Driver, public virtual Plugin, public virtual CmdObject But then, in the implementation of a virtual method in NewDriver, I tried to call the Mgr::RegisterPlugin method that takes a Plugin*, and I got this: ".\NewDriver.cpp", line 89: cc0286: error: base class "Plugin" is ambiguous if (!m_pMgr->RegisterPlugin(this)) How is the this pointer ambiguous, and how do I resolve it? Thanks, --Paul

  • Creating a multi-step process with mysql and php

    - by Paul Atkins
    Hi, I am working on a script which allows users to create a stepped process. The steps will consist of sending visitors to urls where they will fill out a form then be directed to the next step the user has created. Each user can create as many steps as they wish and the url for each step will be unique. I am not sure if I am doing this in the correct/most efficient way so I have a few questions about this. Before I begin here is a simple version of my table structure: step_id user_id step_url step_order 1 1 example.com?step=1 1 2 2 test.com?step=1 1 3 1 example.com?step=3 2 A visitor will be directed to step_url: example.com?step=1 by user_id: 1 On this page there will be a form which contains a hidden field with the value of the step_id like this: <input type="hidden" name="step_id" value="1"> Once the visitor has filled out this form it will be processed by my script at a url similar to: http://mysite.com/form-process.php Once the form has been submitted I then need to direct the visitor to the next step my user has created. I would currently do this using code similar to this: SELECT step_url FROM table WHERE step_order='$current_step_order'+1 Here are my questions about this: Is this the best most efficient way to accomplish this? Or is there a better way? As the step_id column is auto increment...how would I increment the order column by 1 each time a user inserts a new step? Thanks for taking the time to read this. Paul

  • How does Entity Framework 4.0 determine which parameters are required for the factory method of an e

    - by Scott Davies
    Hi, I am working with Entity Framework 4.0 (VS 2010 Beta 2, NOT RC). I can model the EDM and produce the required database. When I ask VS to generate the code for the model, it generates the expected .designer.cs file. When I look at the factory methods for each entity that the designer has generated, I've noticed that it doesn't include all of the properties of the entity. Is it correct to say that the factory method only includes properties that cannot be null ? This appears to be the case, but I'm not entirely sure. Thanks, Scott

  • Windows Service Conundrum

    - by Paul Johnson
    All, I have a Custom object which I have written using VB.NET (.net 2.0). The object instantiates its own threading.timer object and carries out a number of background process including periodic interrogation of an oracle database and delivery of emails via smtp according to data detected in the database. The following is the code implemented in the windows service class Public Class IncidentManagerService 'Fakes Private _fakeRepoFactory As IRepoFactory Private _incidentRepo As FakeIncidentRepo Private _incidentDefinitionRepo As FakeIncidentDefinitionRepo Private _incManager As IncidentManager.Session 'Real Private _started As Boolean = False Private _repoFactory As New NHibernateRepoFactory Private _psalertsEventRepo As IPsalertsEventRepo = _repoFactory.GetPsalertsEventRepo() Protected Overrides Sub OnStart(ByVal args() As String) ' Add code here to start your service. This method should set things ' in motion so your service can do its work. If Not _started Then Startup() _started = True End If End Sub Protected Overrides Sub OnStop() 'Tear down class variables in order to ensure the service stops cleanly _incManager.Dispose() _incidentDefinitionRepo = Nothing _incidentRepo = Nothing _fakeRepoFactory = Nothing _repoFactory = Nothing End Sub Private Sub Startup() Dim incidents As IList(Of Incident) = Nothing Dim incidentFactory As New IncidentFactory incidents = IncidentFactory.GetTwoFakeIncidents _repoFactory = New NHibernateRepoFactory _fakeRepoFactory = New FakeRepoFactory(incidents) _incidentRepo = _fakeRepoFactory.GetIncidentRepo _incidentDefinitionRepo = _fakeRepoFactory.GetIncidentDefinitionRepo 'Start an incident manager session _incManager = New IncidentManager.Session(_incidentRepo, _incidentDefinitionRepo, _psalertsEventRepo) _incManager.Start() End Sub End Class After a little bit of experimentation I arrived at the above code in the OnStart method. All functionality passed testing when deployed from VS2005 on my development PC, however when deployed on a true target machine, the service would not start and responds with the following message: "The service on local computer started and then stopped..." Am I going about this the correct way? If not how can I best implement my incident manager within the confines of the Windows Service class. It seems pointless to implement a timer for the incidentmanager because this already implements its own timer... Any assistance much appreciated. Kind Regards Paul J.

  • How does one calculate CPU utilization programmatically ?

    - by Scott Davies
    Hi, I have a benchmarking program that calculates the time (in milliseconds and ticks), for a persistance to Entity Framework 4.0. Is there a way to calculate CPU load ? I am guessing that I would need to query Windows to find out my CPU frequency, how many cores, etc. Does this sound right ? If so, what part of the .NET framework relates to querying the system ? I am guessing System.Diagnostics ? Thanks, Scott

  • how to insert multiple rows using cakephp

    - by Paul
    In the cakePHP project I'm building, I want to insert a defined number of identical records. These will serve as placeholders records that will have additional data added later. Each record will insert the IDs taken from two belongs_to relationships as well as two other string values. What I want to do is be able to enter a value for the number of records I want created, which would equate to how many times the data is looped during save. What I don't know is: 1) how to setup a loop to handle a set number of inserts 2) how to define a form field in cakePHP that only sets the number of records to create. What I've tried is the following: function massAdd() { $inserts_required = 1; while ($inserts_required <= 10) { $this->Match->create(); $this->Match->save($this->data); echo $inserts_required++; } $brackets = $this->Match->Bracket->find('list'); $this->set(compact('brackets')); } What happens is: 1) at the top of the screen, above the doc type, the string 12345678910 is displayed, this is displayed on screen 2) a total of 11 records are created, and only the last record has the values passed in the form. I don't know why 11 records as opposed to 10 are created, and why only the last records has the entered form data? As always, your help and direction is appreciated. -Paul

  • Help with MySQL query - Product orders report without duplicate shipping charges

    - by Paul
    Hello, I have an issue creating a custom report for an e-commerce store running on osCommerce. The client wants the report to have the following columns: Date, Order ID, Product Class, Product Price, Product Tax, Shipping, Order Total The criteria for generating the report are Date Range and Product Class (Textbooks for example) The client wants the report to list each Textbook purchased on its own line. Orders with multiple textbooks would display a separate line for each Textbook in the order. I have it all working except for one part: the shipping amount is order-specific (based on the order total), not product-specific, and is displaying for each product. I need it to display only for the first product of each order, so it is not counted more than once. My current query is: SELECT op.date_funds_captured as 'Date', op.orders_id as 'Order ID', pc.class as 'Product Class', round(op.products_price,2) as 'Product Price', round(op.products_tax*op.products_price/100,2) as 'Product Tax', round(otship.value,2) as 'Shipping', round(ot.value,2) as 'Order Total' from orders_products op, orders_total ot, orders_total otship, productclasses pc, products p where ot.orders_id = op.orders_id and ot.class='ot_total' and op.orders_id = otship.orders_id and otship.class = 'ot_shipping' and p.products_class_id = pc.id and op.products_id = p.products_id and pc.id = 1 pc.id = 1 -- Product class = Textbook Here is an example of the current report output. You can see the problem with order 2256 showing the shipping value three times instead of once: Date Order Product Class Price Tax Shipping Total 2010-01-04 2253 Textbook 24.95 2.43 10.03 37.41 2010-01-04 2256 Textbook 34.95 0.00 18.09 240.37 2010-01-04 2256 Textbook 55.50 0.00 18.09 240.37 2010-01-04 2256 Textbook 36.95 0.00 18.09 240.37 2010-01-04 2258 Textbook 55.50 5.41 12.17 124.24 Please help!!!

  • IE performance issues with offsetHeight and offsetWidth

    - by Paul
    I have a site that grabs the response text from an AJAX call and does 'innerHTML' on a div that is going to contain it. After I do the 'innerHTML' I process the DIV by traversing the whole hierarchy of nodes and grabbing their [offsetWidth/offsetHeight] to do some operations with it. Why not css style width/height? because sometimes those values are not available since I don't control what is coming from the AJAX response, plus I want the real box dimensions including borders/scrolls/padding. On large injections (let's say 7,000 new DOM elements) IE takes way longer time than FF/Safari just to get this [offsetWidth/offsetHeight], actually if I wasn't doing injection but just render the contents of the HTML in the browser and processing it, it would be much faster. But that is not an option since I have to inject it on a div that will contain it. Anybody has deal with this kind of issue before? is there an alternative to innerHTML, I have try using documentFragment to inject and process and the move it to the div and still I don't see much gain. How can I get the values that are available with [offsetWidth/offsetHeight]? Thanks a bunch for any suggestions. Paul

  • How do I write test code to exercise a C# generic Pair<TKey, TValue> ?

    - by Scott Davies
    Hi, I am reading through Jon Skeet's "C# in Depth", first edition (which is a great book). I'm in section 3.3.3, page 84, "Implementing Generics". Generics always confuse me, so I wrote some code to exercise the sample. The code provided is: using System; using System.Collections.Generic; public sealed class Pair<TFirst, TSecond> : IEquatable<Pair<TFirst, TSecond>> { private readonly TFirst first; private readonly TSecond second; public Pair(TFirst first, TSecond second) { this.first = first; this.second = second; } ...property getters... public bool Equals(Pair<TFirst, TSecond> other) { if (other == null) { return false; } return EqualityComparer<TFirst>.Default.Equals(this.First, other.First) && EqualityComparer<TSecond>.Default.Equals(this.Second, other.Second); } My code is: class MyClass { public static void Main (string[] args) { // Create new pair. Pair thePair = new Pair(new String("1"), new String("1")); // Compare a new pair to previous pair by generating a second pair. if (thePair.Equals(new Pair(new string("1"), new string("1")))) System.Console.WriteLine("Equal"); else System.Console.WriteLine("Not equal"); } } The compiler complains: "Using the generic type 'ManningListing36.Paie' requires 2 type argument(s) CS0305" What am I doing wrong ?

  • Is it possible to dynamically discover tables in an Entity Framework model ?

    Hi, I have co-workers working on an Entity Framework model that changes structure (entities), over time as software development progresses. I've written some utilities that interact with the tables within the model, but I'd like to have the code dynamically discover the tables. Is there a way I can do this ? Perhaps with ADO.NET to get the table names and then store them in a collection ? Thanks, Scott

  • How to query JDO persistent objects in unowned relationship model?

    - by Paul B
    Hello, I'm trying to migrate my app from PHP and RDBMS (MySQL) to Google App Engine and have a hard time figuring out data model and relationships in JDO. In my current app I use a lot of JOIN queries like: SELECT users.name, comments.comment FROM users, comments WHERE users.user_id = comments.user_id AND users.email = '[email protected]' As I understand, JOIN queries are not supported in this way so the only(?) way to store data is using unowned relationships and "foreign" keys. There is a documentation regarding that, but no useful examples. So far I have something like this: @PersistenceCapable public class Users {     @PrimaryKey     @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)     private Key key;     @Persistent     private String name;         @Persistent     private String email;         @Persistent     private Set<Key> commentKeys;     // Accessors... } @PersistenceCapable public class Comments {     @PrimaryKey     @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)     private Key key;     @Persistent     private String comment;         @Persistent     private Date commentDate;     @Persistent     private Key userKey;     // Accessors... } So, how do I get a list with commenter's name, comment and date in one query? I see how I probably could get away with 3 queries but that seems wrong and would create unnecessary overhead. Please, help me out with some code examples. -- Paul.
