• Should I send patch against 2-3-stable or master

  - by Nadal

  I am trying to find a way to contribute back to rails. I was thinking I should validate if this patch https://rails.lighthouseapp.com/projects/8994/tickets/4154-expires_now-broken works or not. I was able to validate the problem. The problem still exists in 2.3.5 and in 2-3-stable branch of rails. I was not able to apply his patch at 2-3-stable branch of rails . Also the patch failed for master branch. Looked at the diff and manually changed the code and the new code solves the bug. Now if I want to attach my patch to the ticket should I create my patch against 2-3-stable branch or master branch? I believe master is more closely aligned with rails3 changes.

• Display path of file in status bar

  - by robUK

  Hello GNU Emacs 23.1.1 I am wondering is there a way to display the path of the file in the status bar, instead of just the filename. I have to open many files in many directories, and sometimes I forget what directory they are in. Just easier to display the some of the path in the status bar if that is possible. Sometimes my directory paths are very long. for example /projects/clientserver/trunk/src/client/client.c like this in the status bar, just display the last two directories. /src/client/client.c Many thanks for any suggestions,

• Which one is better to have auto-implemented property with private setter or private field and property just getter?

  - by PLB

  My question may be a part of an old topic - "properties vs fields". I have situation where variable is read-only for outside class but needs to modified inside a class. I can approach it in 2 ways: First: private Type m_Field; public Type MyProperty { get { return m_Field; } } Second: public Type MyProperty { get; private set; } After reading several articles (that mostly covered benefits of using public properties instead of public fields) I did not get idea if the second method has some advantage over the first one but writing less code. I am interested which one will be better practice to use in projects (and why) or it's just a personal choice. Maybe this question does not belong to SO so I apologize in advance.

• Hudson + gitolite + virtual host on staging server

  - by takeshin

  I have a Ubuntu server which I want to be my continous integration server (for the Zend Application based projects) and the staging server as well. The team is pushing source files to the repository: /home/git/repositories/testing.git Then Hudson does the build, and the master branch is exported (maybe cloned is a better word) by git hudson plugin to: /var/lib/hudson/jobs/test/workspace/ The workspace contains .git folder as well, which is not necessary on my staging website. How do you set up virtual host to see the staging version of the content of the repository? Does the virtual host point to the workspace, or shall I export the files to another directory? What about the permissions and security? Hudson is the owner of all the workspace files. Do I have to do some post-build actions to set up access? P.S. If this question is more apropriate to serverfault, please migrate.

• How to avoid Mercurial repo corruption when sharing a repository between Windows/Mac?

  - by Stabledog

  I have several projects which are shared between Windows and Mac. The dev machine is a Mac running Parallels: the files are stored on the Mac side, and the source is shared to the Windows side. This is very convenient, as I can switch back and forth between Windows and Mac tools rapidly without having to sync files. Recently I switched from Subversion to Mercurial, and now I'm having problems with the Mercurial repository becoming corrupt if I use the Windows tools to add/update, etc. I have to be very careful about which operations on the Windows side are safe (mainly the read-only stuff) and of course I forget rather regularly. Does anybody know why the corruption occurs? I thought Mercurial repositories were platform-agnostic. Any ideas how to prevent it without removing the Windows tools entirely?

• "There was an internal API error." while running an app on any iPhone/iPod-touch device

  - by Martin Cowie

  I am in the process of submitting an iPhone app to the app store. While making the final touches to the app I was in the process of compiling and running the app on my iPhone when I got the message ... "There was an internal API error." The console had this to say ... 25/08/2010 10:10:54 Xcode[3556] Failed willExecute: Error Domain=com.apple.platform.iphoneos Code=0 UserInfo=0x2011adec0 "There was an internal API error." -- { NSLocalizedDescription = "There was an internal API error."; NSLocalizedFailureReason = ""; NSLocalizedRecoverySuggestion = ""; } The problem is specific to this project, others projects don't suffer the same problem. The same problem exhibits when moved to another machine, or another mobile device is swapped in. I should be most grateful for any hints or ideas on the subject ...

• When does code bloat start having a noticeable effect on performance?

  - by Kyle

  I am looking to make a hefty shift towards templates in one of my OpenGL projects, mainly for fun and the learning experience. I plan on watching the size of the executable carefully as I do this, to see just how much of the notorious bloat happens. Currently, the size of my Release build is around 580 KB when I favor speed and 440 KB when I favor size. Yes, it's a tiny project, and in fact even if my executable bloats 10 x its size, it's still going to be 5 MB or so, which hardly seems large by today's standards... or is it? This brings me to my question. Is speed proportional to size, or are there leaps and plateaus at certain thresholds, thresholds which I should be aiming to stay below? (And if so, what are the thresholds specifically?)

• Advantages of GitHub over Bitbucket for Git Repositories [closed]

  - by rolve

  Now that Bitbucket also supports Git repositories, it seams to me that it is a good alternative to GitHub, especially since its free plan includes unlimited private repositories, which is not available on GitHub. Yet, GitHub seams much more popular. Are there any major reasons to choose GitHub as the hosting site for Git repositories instead of Bitbucket? (Although I have no problems with making my personal projects publicly available in general, I like the idea of being able to make the switch from public to private or vice versa any time I want. But if there are some good reasons to use GitHub, I would be willing to give up this freedom.)

• java.lang.NoClassDefFoundError when the file is there

  - by tsOverflow

  I've tried to look around for postings that might help me, cant find any. I am deploying an ear to JBoss4 server, and I started having this problem since I added a new project. this new project is defined as Java project in eclipse, and the EAR project has an EJB project that has the new Java project as one of the projects as its dependent upon - if deployed on JBoss locally through eclipse, there's no problem and everything goes smoothly But when being deployed to JBoss in test environment (outside eclipse), kept getting java.lang.NoClassDefFoundError on one of the classes that are defined in the new Java project. I looked inside the EAR file to get to the jar (EJB project), and then inside the jar, I can see the directory structure and all the class files from the new Java project - ie. The class that it complains about is right there inside the EAR-JAR and matching the exact structure that it's looking for. I am at lost to what else I can look at. Any pointers are greatly appreciated! Thanks

• Custom librairies with Razor with the release version of MVC 3

  - by Maxim

  So I'm developing an in-house library for MVC 3 and I want to add it to my project. I added it to my web.config. I added the assembly and added it to the pages - namespaces section and... no. Doesn't work. I tried recompiling, etc... but Razor doesn't like it at all. It's not an intellisense problem... the site can't run if I use my defined namespace. The only way that I made it work was by using the following statements: @using Sample.Helpers I don't want to use it in the pages. I want to be able to deploy it to many projects and adding it to the web.config is definitely the way to go. Anyone ran into this problem?

• VS2008 project with Entity Framework model results in "always dirty" compile

  - by Jeremy Lew

  In VS 2008, I have a simple .csproj that contains an Entity Framework .edmx (V1) file. Every time I build the project, the output DLL is updated, even though nothing has changed. I have reproduced this in the simplest-possible project (containing one ordinary .cs file and one edmx model). If I remove the edmx model and build repeatedly, the output assembly will not be touched. If I add the edmx model and build repeatedly, the output assembly is modified each time. This is a problem because the real project is a dependency of dozens of other projects and it is wreaking havoc with what times when working in higher layers of the application. Is this a known problem? Any way to fix it? Thanks!

• Where to place web server root?

  - by nefo_x

  Hello everybody, I've just made an upgrade and now partly thinking on web-server directory structure for local workstation for web-development on linux platform. Running multiple hosts and different projects required. Where is it better to put all the server's docroots? /var/www? /srv? /www? I plan to make it as separate partition - could it be good for backups? :) I'm looking forward to your thoughts on this.

• SVN correct directory structure

  - by jax

  I followed this tutorial to setup SVN on my Fedora box http://www.ashishkulkarni.com/installing-subversion-on-fedora-linux/ It worked. However, there is no trunk, tags or branches when I set this up. In the tutorial he creates a sandbox project /svn/repos/sandbox Now I am assuming that all projects will go under repos /svn/repos/project1 /svn/repos/project2 When I view the project there are no trunk, tags or branches, I have not yet checked in any project, will these appear when I do that? As I understand all my files should go below the trunk. What are the tags and branches for? Just some clarification about the structure would be nice. Thanks.

• VS 2010 Error “Object reference not set to an instance of an object” when adding Service Reference f

  - by Andy

  I have a VS2010 (RTM) solution which contains: WCF Service project Console WCF client project Class project for DataContracts and members Class project for some simple classes I successfully added a service reference in the console client project and ran the client. I then did a long dev cycle repeatedly modifying the service then updating console service reference. I then changed the namespace and assembly names for the projects as well as the .cs using references and app.config. I of course missed some things as it would not build so I eventually removed the project references and the service reference, cleaned and built successfully. I then attempted to add the service reference again, it discovered it but threw the “Object reference not set to an instance of an object” when OK'ing. Fix in answer below...

• Building a user subscription application

  - by Tristan O'Neil

  Hello, I'm trying to come up with the best way to handle user subscription and management for our magazine website. What I want to happen is a user purchases a subscription and they are granted online access of a certain membership role for a certain amount of time depending on how many years they subscribed for. I would also like the system to be able to send out emails when a subscription is almost up. I've seen some third party projects to help accomplish this but I'd prefer to write this from scratch as I want total control over how it works. Any suggestions would be helpful. The main thing I can't figure out is how to have an expiring membership. You must keep track of when the user signed up and how long until they should expire.

• How do you deal with the more mundane parts of programming tasks?

  - by Uri

  My experience as a developer is that many projects or tickets are a mix of a short and focused very interesting task (e.g., designing some API or a platform to solve something) and a lot of repetitive and mundane tasks that cannot be automated (such as certain refactorings to use the API or platform, implementation of certain tests, some GUI handling, etc). I believe that this is the nature of our profession, unless we are high-level architects or managements and can delegate this work. The only item in my personal arsenal when dealing with these tasks is to devote some of my attention to radio or audiobooks (preferably not in English as I find it hard to concentrate on two "streams" of English at the same time). I maintain sufficient attention to carry the task and don't lose concentration as fast. I'm wondering how others cope with these and maintain concentration.

• Should I start with Trac 0.12 ?

  - by mree

  I'm going to start using Trac for the first time. From what I've gathered, the latest 0.12 is capable of supporting multiple project easily (which is something I will need since I got about 5 projects). However, it seems 0.12 is still in the development (0.12-dev). So, my question is, is it good enough for a newbie in Trac like me to use it? Does anyone has any experience using it ? It will be installed on a Linux server. BTW, I'll only be using the basic functions such as svn browser, wiki, tickets and others.

• NServiceBus - Message Sent to and Removed from Queue, but Never Fire IHandleMessages.Handle

  - by grefly

  First let me state, today is my first day using NSesrviceBus - so I hope my question isn't too elementary. I have managed to set up Sender, Receiver, and Messages projects. When I debug the Sender, I see the messages show up in the configured queue. When I debug the Receiver, the messages are removed from the queue. However, my IHandleMessages Handle event never fires, and no Console output is displayed. I'm sure I've done something wrong (I think I may have mixed tutorials from different versions of NServiceBus) - any suggestions would be appreciated.

• Explain the code: c# locking feature and threads

  - by Mendy

  I used this pattern in a few projects, (this snipped of code is from CodeCampServer), I understand what it does, but I'm really interesting in an explanation about this pattern. Specifically: Why is the double check of _dependenciesRegistered. Why to use lock (Lock){}. Thanks. public class DependencyRegistrarModule : IHttpModule { private static bool _dependenciesRegistered; private static readonly object Lock = new object(); public void Init(HttpApplication context) { context.BeginRequest += context_BeginRequest; } public void Dispose() { } private static void context_BeginRequest(object sender, EventArgs e) { EnsureDependenciesRegistered(); } private static void EnsureDependenciesRegistered() { if (!_dependenciesRegistered) { lock (Lock) { if (!_dependenciesRegistered) { new DependencyRegistrar().ConfigureOnStartup(); _dependenciesRegistered = true; } } } } }

• Are there any pitfalls to having two different Models from two different assemblies? (EF)

  - by Jonn

  I have two projects, both of them data access layers, and both using EF. I have another project calling services related to the two different assemblies. Are there any pitfalls on using two different models on two different databases linked to the same database? I'm asking this because I've been getting this generic "EntitySqlException" could not be resolved in the current scope or context. Make sure that all referenced variables are in scope, that required schemas are loaded, and that namespaces are referenced correctly., near escaped identifier. that does not appear when are run separately but appear when under the same project.

• Sticky notes associated with web page - how to?

  - by volvox

  I have this idea for a project. Associated with any web page, i want to create notes that will be saved locally in a database, the notes will be reloaded automatically from that database the next time i visit the same page. Creating the note is easy, but i'm looking for how to link the notes to the web page url and how to keep aware of the active web page. Any idea? (Note: i have come to this searching on the internet: http://webkit.org/demos/sticky-notes/ - this is part of WebKit Open source projects) - this is about what i'm looking for. Thank.

• How to force Maven to download maven-metadata.xml from the central repository?

  - by Alceu Costa

  What I want to do is to force Maven to download the 'maven-metadata.xml' for each artifact that I have in my local repository. The default Maven behaviour is to download only metadata from remote repositories (see this question). Why I want to do that: Currently I have a remote repository running in a build machine. By remote repository I mean a directory located in the build machine that contains all dependencies that I need to build my Maven projects. Note that I'm not using a repository manager like Nexus, the repository is just a copy of a local repository that I have uploaded to my build machine. However, since my local repository did not contain the 'maven-metadata.xml' files, these metadata files are also missing in the build machine repository. If I could retrieve the metadata files from the central repository, then it would be possible to upload a working remote repository to my build machine.

• Scheduling a visual studio load test using powershell giving me BSOD

  - by user952342

  I have a visual studio load test which I want to run every hour so that I can start to collect some data. To do this, I thought it would be best to make a little powershell script and put a command like this inside: Invoke-Expression -command "& '$env:VS100COMNTOOLS..\IDE\mstest.exe' /testcontainer:"C:\Users\benb\Documents\Visual Studio 2010\Projects\BBPerformanceTest\bin\Debug\HomePageOnly.loadtest"" That command works fine, but sometimes when its run I get a blue screen of death. However, when I run my load test through the visual studio GUI, I never get a BSOD. two questions: is it possible to avoid this BSOD? Is there another way I can schedule my load test? Thanks

• Maven: Variables are not replaced in installed and deployed POM

  - by mmuthu

  We have been trying to migrate our multi-module projects to maven. I have been struggling with the maven install plugin bug "http://jira.codehaus.org/browse/MNG-2971". I have written a Java program which can find and replace the expressions using my settings.xml and POM in my local repository view. As a result all of my parent POM's are having a additional phase in the build process. What i'm doing is that i have attached a goal which will run my Java program during "validate" phase. I think this is a not a good idea instead i would have asked individuals to run the program on their local repository on their own. What i'm asking here is that the best way to work around the "install" plugin issue (MNG-2971). I searched through the net but i could not locate such work around.
