• Apt pin and self hosted apt repo

  - by Hamish Downer

  We have our own apt/deb repository with a handful of packages where we want to control the version. Crucially this includes puppet, which can be sensitive to versions being different. I want our desktops to only get puppet from our repository, but also for people to be able to add their own PPAs, enable backports etc. The current problem we have is backports on Ubuntu Lucid. Some important lines from /etc/apt/sources.list: deb http://gb.archive.ubuntu.com/ubuntu/ lucid main restricted universe multiverse deb http://gb.archive.ubuntu.com/ubuntu/ lucid-updates main restricted universe multiverse deb http://gb.archive.ubuntu.com/ubuntu/ lucid-backports main restricted universe multiverse deb http://security.ubuntu.com/ubuntu/ lucid-security main restricted universe multiverse deb http://deb.example.org/apt/ubuntu/lucid/ binary/ And in /etc/apt/preferences.d/puppet: Package: puppet puppet-common Pin: release a=binary Pin-Priority: 800 Package: puppet puppet-common Pin: release a=lucid-backports Pin-Priority: -10 Currently policy says: $ sudo apt-cache policy puppet puppet: Installed: (none) Candidate: (none) Package pin: 2.7.1-1ubuntu3.6~lucid1 Version table: 2.7.1-1ubuntu3.6~lucid1 -10 500 http://gb.archive.ubuntu.com/ubuntu/ lucid-backports/main Packages 100 /var/lib/dpkg/status 2.6.14-1puppetlabs1 -10 500 http://deb.example.org/apt/ubuntu/lucid/ binary/ Packages 0.25.4-2ubuntu6.8 -10 500 http://gb.archive.ubuntu.com/ubuntu/ lucid-updates/main Packages 500 http://security.ubuntu.com/ubuntu/ lucid-security/main Packages 0.25.4-2ubuntu6 -10 500 http://gb.archive.ubuntu.com/ubuntu/ lucid/main Packages If I use n= instead of a= then I get Package pin: (not found) I'm just plain confused at this point as to what I should use. Any help appreciated.

• Is context inheritance, as shown by Head First Design Patterns' Duck example, irrelevant to strategy pattern?

  - by Korey Hinton

  In Head First Design Patterns it teaches the strategy pattern by using a Duck example where different subclasses of Duck can be assigned a particular behavior at runtime. From my understanding the purpose of the strategy pattern is to change an object's behavior at runtime. Emphasis on "an" meaning one. Could I further simplify this example by just having a Duck class (no derived classes)? Then when implementing one duck object it can be assigned different behaviors based on certain circumstances that aren't dependent on its own object type. For example: FlyBehavior changes based on the weather or QuackBehavior changes based on the time of day or how hungry a duck is. Would my example above constitute the strategy pattern as well? Is context inheritance (Duck) irrelevant to the strategy pattern or is that the reason for the strategy pattern? Here is the UML diagram from the Head First book:

• NHibernateUnitOfWork + ASP.Net MVC

  - by Felipe

  Hi Guys, hows it going? I'm in my first time with DDD, so I'm begginer! So, let's take it's very simple :D I developed an application using asp.net mvc 2 , ddd and nhibernate. I have a domain model in a class library, my repositories in another class library, and an asp.net mvc 2 application. My Repository base class, I have a construct that I inject and dependency (my unique ISessionFactory object started in global.asax), the code is: public class Repository<T> : IRepository<T> where T : Entidade { protected ISessionFactory SessionFactory { get; private set; } protected ISession Session { get { return SessionFactory.GetCurrentSession(); } } protected Repository(ISessionFactory sessionFactory) { SessionFactory = sessionFactory; } public void Save(T entity) { Session.SaveOrUpdate(entity); } public void Delete(T entity) { Session.Delete(entity); } public T Get(long key) { return Session.Get<T>(key); } public IList<T> FindAll() { return Session.CreateCriteria(typeof(T)).SetCacheable(true).List<T>(); } } And After I have the spefic repositories, like this: public class DocumentRepository : Repository<Domain.Document>, IDocumentRepository { // constructor public DocumentRepository (ISessionFactory sessionFactory) : base(sessionFactory) { } public IList<Domain.Document> GetByType(int idType) { var result = Session.CreateQuery("from Document d where d.Type.Id = :IdType") .SetParameter("IdType", idType) .List<Domain.Document>(); return result; } } there is not control of transaction in this code, and it's working fine, but, I would like to make something to control this repositories in my controller of asp.net mvc, something simple, like this: using (var tx = /* what can I put here ? */) { try { _repositoryA.Save(objA); _repositoryB.Save(objB); _repositotyC.Delete(objC); /* ... others tasks ... */ tx.Commit(); } catch { tx.RollBack(); } } I've heared about NHibernateUnitOfWork, but i don't know :(, How Can I configure NHibernateUnitOfWork to work with my repositories ? Should I change the my simple repository ? Sugestions are welcome! So, thanks if somebody read to here! If can help me, I appretiate! PS: Sorry for my english! bye =D

• Fine-grained permissions on SVN Repository

  - by Jim

  Hello, I'm trying to setup a SVN repo for a whole bunch of users. Different users need to have different levels of access to areas of the repository. A trivial example might be that frontend engineers need access to the "view" and "controllers" but not "model", while backend engineers need access to the "controllers" and "model" but not "view". It needs to be one repository, because (as far as I know) that's the only way to ensure that commits touching multiple modules are atomic. Is there a fine-grained way to control user access to a repository? Thanks!

• Using MobileMe idisk as a git repository

  - by Ben Guest

  I am trying to use git and MobileMe as a version control system for a personal project I am working across several computers. So far i have done the following. Created and empty bare repository on my local computer $ mkdir myproject.git $ cd myproject.git $ git init --bare $ git update-server-info I then copied the myproject.git directory to the mobile me disk, and sync my computer with mobile me. I then switched to the directory where my project was on my local machine, set the remote origin and try to push the local repository to mobile me $ cd myproject $ git remote add origin https://<username>@idisk.me.com/<username>/myproject.git/ $ git push --all Im am then asked for my password twice. The first time is the mobile me password, any other password gets an error. After entering the second password, and believe me i've tried everything, terminal just hangs. So what am I doing wrong? (Besides trying to use mobileme as a git repository) Thanks, Ben.

• Trac: Changesets lost after changing SVN repository path

  - by synapse

  Last evening I did some housekeeping on our code repository - basically moved the code from /repo/trunk to /repo/projectname/trunk. I changed the repo path on my trac.ini - after which trac complained the repository needed to be resynced. So I ran: trac-admin /var/trac/projectname resync and all was well. Then I checked the changesets against the ticket and found that trac no longer has a link to show the code against changesets - says "No changeset XXX in repository". Has anyone here had the same issue they managed to solve? I need the broken links to the changeset fixed. Thank you

• Servlet mapping url patterns

  - by Scobal

  I have the following urls that need mapping to two different servlets. Can anyone suggest a working url-pattern please? vehlocsearch-ws: /ws/vehlocsearch/vehlocsearch /ws/vehavailrate/vehavailratevehlocsearch /ws/vehavailrate/vehavailratevehlocsearch.wsdl vehavailrate-ws: /ws/vehavailrate/vehavailrate /ws/vehavailrate/vehavailratevehavailrate /ws/vehavailrate/vehavailratevehavailrate.wsdl So far I have this, which feels right, but isn't: <servlet-mapping> <servlet-name>vehlocsearch-ws</servlet-name> <url-pattern>*.vehlocsearch*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>vehavailrate-ws</servlet-name> <url-pattern>*.vehavailrate*</url-pattern> </servlet-mapping> Note: I have no control over the incoming urls

• Committing file deletions to svn repository whilst ignoring some other local mods

  - by TheJuice

  I have svn repository where I have scheduled some files and folders to be moved in the repository with svn mv. I also have some files that are peers of the files to be moved that have local modifications of which I only want a subset of those files to be committed along with the moves. e.g. the output of svn st would look like: D foo/bar D foo/bar/a.txt D foo/bar/b.txt M foo/exclude.txt M foo/include.txt A foo/whiz/bar A + foo/whiz/bar/c.txt A + foo/whiz/bar/d.txt To commit to the moves to the repository, I would need to perform the commit on foo but that would also commit the modifications to foo/exclude.txt and foo/include.txt. How would I commit only the deletions/additions as a result of the move plus the mods to foo/include.txt whilst excluding foo/exclude.txt? I have a feeling the answer lies with the --depth argument to svn ci but it's not clear to me how it will operate.

• Custom capistrano task for working with scm repository

  - by Trevor

  Is there any way to create a custom capistrano task for performing other actions on a scm repository? For instance, I would like to create a task that will checkout a particular folder from my repository and then symlink it into the shared/ directory of the main project on my server. I know this can be done by creating a task and explicity defining the "svn co ..." command along with the scm username, password, and repository location. But this would display the password in plain text. Are there any built-in capistrano variables/methods that would help in this process?

• Caching the repository index in m2eclipse

  - by Titi Wangsa bin Damhore

  everytime i start with a fresh new workspace, m2eclipse downloads nexus-maven-repository-index.gz from the maven central repository. this is good. but, some times, i just want to start a new workspace, and not wait for it to download, it tried copying the whole .metadata directory from an old workspace to the new one, but the list of maven artifacts are still empty. is there a way i can cache it? or at least download the file once, and the copy/extract/repackage it so that m2eclipse thinks it has already downloaded it and allows me to search for maven artifacts. or a short version of the question where and in what format is the "nexus-maven-repository-index.gz" file stored in the workspace?

• How to prevent maven to resolve dependencies in local repository

  - by Nils Schmidt

  Is there a way to tell maven (when doing mvn package, mvn site or ...) not to resolve the dependencies from the local repository? Background of this question: Sometimes I get into problems, when previously cached dependencies (e.g. SomeProject-0.7-ALPHA) are no longer available in the remote repository. In my local build everything still works fine as the dependency has been cached before. As soon as I share my pom with others, they may get into trouble, as they dont have a cached version of that dependency and the dependency can no longer be resolved from the remote repository. Any help will be appreciated. Thanks in advance!

• Structure of open source project's repository

  - by hokkaido

  I'm in the beginning of starting a small open source project. When cloning the main repository one gets a complete build environment with all the libraries and all the tools needed to make an official installer file, with correct version numbers. I like the fact that anyone who wants to contribute can clone the repository and get started with anything they want. But I'm thinking this makes it to easy for Evil People to create malicious installers and release into the wild. How should it be structured? What do you recommend including in the repository, versus keeping on the build server only?

• Heroku- was working before computer restarted, now can't push to remote repository- access denied

  My heroku/git set up was working perfectly until I restarted my computer. Now when I attempt to push any change to the remote repository I get the following error. ! Your key with fingerprint ..... is not authorized to access ..... fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. I tried looking at heroku keys:add but that didn't seem to make any difference. Any ideas? Thanks!

• Websphere federated repository for Active Directory

  - by Drakiula

  Hi, What I am trying to achieve is to have Websphere 6.1 use Active Directory users authentication. Websphere is running on Windows 2008 R2. What I've done already: Succesfully setup a federated repository for Windows Active Directory (LDAP); Create a realm definition for the federated repository previously defined; Set the realm definition as the current real definition. Stop the Websphere service. When I attempt to start the Websphere service again, it crashes with the following stacktrace: ------Start of DE processing------ = [9/3/10 2:36:14:133 PDT] , key =

• Why is ExecuteFunction method only available through base.ExecuteFunction in a child class of Object

  - by Matt

  I'm trying to call ObjectContext.ExecuteFunction from my objectcontext object in the repository of my site. The repository is generic, so all I have is an ObjectContext object, rather than one that actually represents my specific one from the Entity Framework. Here's an example of code that was generated that uses the ExecuteFunction method: [global::System.CodeDom.Compiler.GeneratedCode("System.Data.Entity.Design.EntityClassGenerator", "4.0.0.0")] public global::System.Data.Objects.ObjectResult<ArtistSearchVariation> FindSearchVariation(string source) { global::System.Data.Objects.ObjectParameter sourceParameter; if ((source != null)) { sourceParameter = new global::System.Data.Objects.ObjectParameter("Source", source); } else { sourceParameter = new global::System.Data.Objects.ObjectParameter("Source", typeof(string)); } return base.ExecuteFunction<ArtistSearchVariation>("FindSearchVariation", sourceParameter); } But what I would like to do is something like this... public class Repository<E, C> : IRepository<E, C>, IDisposable where E : EntityObject where C : ObjectContext { private readonly C _ctx; // ... public ObjectResult<E> ExecuteFunction(string functionName, params[]) { // Create object parameters return _ctx.ExecuteFunction<E>(functionName, /* parameters */) } } Anyone know why I have to call ExecuteFunction from base instead of _ctx? Also, is there any way to do something like I've written out? I would really like to keep my repository generic, but with having to execute stored procedures it's looking more and more difficult... Thanks, Matt

• Add new SVN "repo" in poorly constructed repo/project setup

  - by Dave Masselink

  Unfortunately, the answer to this question isn't quite as simple as it sounds... but I hope it can still be relatively simple. Please read all the way through before telling me that the answer is: "svnadmin create... duh" I'm working for a company that set up their SVN server in an odd way (at least in terms of what I'm used to). We've all been there, right? Rather than giving each project a separate repository... they have a folder on the server called "/var/www/svn/repos/" which is the actual SVN repo (has conf/, db/, README.txt, etc. in it). Then they distinguish their projects by adding top level folders into the ONE repository (ex: Project1, Project2, etc.) I don't like this setup and might one day get around to converting the setup to what I'm used to, where each project is its own repository (with separate logs, dbs, etc.) But my question is this: What is the best way to add a new empty project to the current setup? Is there anyway to add a new top level folder/project to the repo through use of svnadmin? It can/should just be an empty folder that I'll start building a new project in. I know that I could do this by checking out the whole singular repository and then adding a new top level folder into my local checkout, then re-committing. But I'd really prefer not to do this because someone has created folders/projects that are just GBs of log data... and I don't want to wait through the download of this just to add a single empty folder. Let me know if there is any more info you'd need to know. I do have root/sudo access on the server in question. Thanks in advance for your help! Dave

• Finding a pattern within a string variable in C#

  - by lo3

  Ok i'm working on a project for a 200 level C# course, we are required to create a heads or tails project. Basically the project is setup so that the computer will guess randomly up to 5 times, but on the sixth time it will look into the playersGuessHistory variable setup as a string to see if it can find a match for a pattern of 4 entires, if there is a pattern found the computer will guess the next character after the pattern EX: [HHTT]H [HHTTH]H HHTT being the pattern then the computer would guess H for the next turn. My only problem is that i'm having difficulty setting up the project so that it will look through the playersguesshistory and find the patterns and guess the next character in the history. Any suggestions?

• PRG Pattern and Sticky Forms

  - by Scott Christopherson

  I'm using the PRG pattern on a form of mine. I've never used this approach before and I'm trying to figure something out: Normally, I always just displayed the posted form again when there were validation errors and displayed POST values in the form (sticky form). However with the PRG pattern, the form is displayed after a redirect, so there aren't any POST values. So my question is, how can I implement the PRG pattern and still have sticky forms?
