• Starting work with SVN and basic folder structure.

  - by Eugene

  I have read little about TortoiseSVN and it capabilities, but I just can't understand how should I use basic structure. /trunk /branches /tags I have created FSFS type repo and I have imported basic structure. NB! No checkouts yet. I also have my project files in another place. How should I continue my work from here? Should I checkout repository-place all files in trunk folder-add them-commit them-then create tag for current trunk state-create branche for my goal I'm tring to achive-switch to created branch and work there? By the way my repo is local and whole work too. I thank everyone for help.

• Torotoisesvn import

  - by user481913

  Hi, My developer gave me a compressed file for the whole project from his subversion working copy. I uncompressed that file and used torotoisesvn import to put it into my repository which i host with projectlocker(a svn hosting provider). Now what i want to know is : 1) I want to view the files and the code that has changed since last revision. After doing the import the latest revision is at 8. I want to see what files and code has changed between revision no. 8 and revision no. 7 and maybe able to compare all of it upto revision no. 1. My question is can i do this ? 2)How to view these changes in projectlocker( or if it's the similar process with every svn host provider ) ?

• Git: What is a tracking branch?

  - by jerhinesmith

  Can someone explain a "tracking branch" as it applies to git? Here's the definition from git-scm.com: A 'tracking branch' in Git is a local branch that is connected to a remote branch. When you push and pull on that branch, it automatically pushes and pulls to the remote branch that it is connected with. Use this if you always pull from the same upstream branch into the new branch, and if you don't want to use "git pull" explicitly. Unfortunately, being new to git and coming from SVN, that definition makes absolutely no sense to me. I'm reading through "The Pragmatic Guide to Git" (great book, by the way), and they seem to suggest that tracking branches are a good thing and that after creating your first remote (origin, in this case), you should set up your master branch to be a tracking branch, but it unfortunately doesn't cover why a tracking branch is a good thing or what benefits you get by setting up your master branch to be a tracking branch of your origin repository. Can someone please enlighten me (in English)?

• Drools rules import with wildcard

  - by ZeKoU

  Hello everyone, I am working with Drools rules. Some developers have created rules which I have to put on Guvnor (rules repository) and build packages. In these rules they have import statements with wildcards, for example: import org.drools.runtime.rule.*; When I upload this on Guvnor and try to build, it tells me: Unable to introspect model for wild card imports (org.drools.runtime.rule.*). Please explicitly import each fact type you require. Is it possible to use wildcard imports in Drools rules???

• Architecting a generic search result web control

  - by Bartek Tatkowski

  In a project I'm currently working for we've stumbled upon the need for several kinds of search results presentation controls. The search result are similar, but not identical. For example, in the "office search" result we might want to present the office name and location, while in the "document search" could contain document name, author and publishing date. These fields should be sortable. My current strategy is to employ the Factory pattern and do something like this: ISearchResult officeResults = SearchResultFactory.CreateOfficeSearchResults(data); ISearchResult documentResults = SearchResultFactory.CreateDocumentSearchResults(data); The problem is: I don't know how to implement the markup code. Should I just do Controls.Add(officeResults); in the containing page? Or is there some ASPX trickery to create generic web controls? Or maybe I'm overthinking this and just should create five classes? ;)

• How to specify unique container styles for heterogenous hierarchies using SL3 and TreeView control

  - by rcecil

  Hello, Just look for strategies that have been successful in rendering hierarchies that represent inheritance structures using SL3/4 TreeViews. I need to render certain nodes differently than others, depending upon what kind of container they are (a choice between things, or simply a list of related things, etc.) So far, I've been very successful with the DataTemplate route: I've been able to use a technique described in Ted Glaza's post "Easy DataTemplateSelectors in Silverlight" (you may have retrieve a Google cache of this page). SO what I'm trying to discover is something on the order of a StyleSelector, not a DataTemplateSelector. I'm considering leveraging my current implementations of Glaza's pattern of selector objects to somehow detect the node type and set the ItemContainerStyle there, but it doesn't seem clear right now. Thanks for your thoughts.

• Process a batch of items, return an object to report on status

  - by Naeem Sarfraz

  I'm looking for a pattern (or good practice) for the following scenario: My function List<BatchItemResponse> Process(List<BatchItem> Data) {..} will process a list of data, and return info on where each item in the batch could be processed. struct BatchItemResponse { int BatchItemID; bool Processed; string Description; } Any thoughts? Is what I've proposed as good as it gets?

• Key Value Observation (ala Cocoa) in GWT ?

  - by user179997

  Hi all, There are these 2 frameworks out there in the same "cloud application" space as GWT: Sproutcore and Cappuccino. Cappuccino is Cocoa for the web, Sproutcore is Cocoa-like and one very central idea in both is Key Value Observation where the framework itself provides the glue to change all dependencies of an object when it changes, and you only have to declare those dependencies. If that was too poorly expressed please see this presentation: http://www.infoq.com/presentations/subelsky-sproutcore-intro Since the pattern reduces the amount of code you type it reduces the number of bugs. Maybe it's too much to ask but I would like to have that and all the benefits of Eclipse/compiler that come with GWT. Is there support for this in GWT, or a library already developed? Or maybe there is support in some of the component libraries for GWT out there? Thanks

• Git Use Remote Source Durring Push

  - by ThinkBohemian

  I have a local git repository a "central" repo at github. I'm working on a part of a project, while a friend is working on a related piece that is its entirely seperate repo, is it possible for me to simply link directly to my friends repo? For example, the app is called widgets. I have all my code in widgets/app/mycode and my friend is writing code that goes into widgets/plugins/awesome/hiscode. I want to be able to always have http://github.com/mycode/widgets/plugins/hiscode to be a direct link or clone to http://github.com/hiscode/awesome ? It could be possible i'm missing something basic in my question or knowledge of git, if so please ask, and i'll be happy to try to fill in the blanks. I am deploying to my production site via capistrano, so maybe a script of some kind may be easier?? I don't know (that's why i'm posting)!!

• Project Euler #163 understanding

  - by Paul

  I spent quite a long time searching for a solution to this problem. I drew tons of cross-hatched triangles, counted the triangles in simple cases, and searched for some sort of pattern. Unfortunately, I hit the wall. I'm pretty sure my programming/math skills did not meet the prereq for this problem. So I found a solution online in order to gain access to the forums. I didn't understand most of the methods at all, and some just seemed too complicated. Can anyone give me an understanding of this problem? One of the methods, found here: http://www.math.uni-bielefeld.de/~sillke/SEQUENCES/grid-triangles (Problem C) allowed for a single function to be used. How did they come up with that solution? At this point, I'd really just like to understand some of the concepts behind this interesting problem. I know looking up the solution was not part of the Euler spirit, but I'm fairly sure I would not have solved this problem anyhow.

• Why should I use MVVM when it breaks built in functionality

  - by Jakob

  I'm struggling to grasp why MVVM is really a good pattern to implement in riaserivces, To me there's nothing but trouble to it, it just add's another tier that I have to code. I Get that I could change the UI, but really I don't need to. Instead i won't be able to user out of the box functionality with riaservices, datagrid, dataform all controls require some implementation. Why can't it just be simple? Is there really no way to get MVVM to automatically set "IsBusy" and all the dataform edit functionality. It's like reinventing the wheel to me, and it seems that I'd be able to write code much faster just using riaservices

• VisualSVN Server + Trac Authentication Problems

  - by danscott

  I have Trac set up on my VisualSVN server (using Subversion authentication), however every time I navigate to the Trac home page after opening the browser, I get the basic authentication dialog asking me for my username/password. What I would like to do is have a login form in Trac, which would allow me to log in forever using cookies. I have tried installing the AccountManagerPlugin, but I am completely unsure of how to correctly set it up. (I am used to working with IIS on corporate intranets, so this is kind of alien to me) I have managed to bypass the basic authentication dialog by setting this in my httpd-custom.conf: AuthName "Trac" AuthType Basic AuthBasicProvider file AuthUserFile "E:/Repositories/htpasswd" #Require valid-user I have tried using SvnServePasswordStore as my password store but I do not know which of the files in the repository directory to point it at. Help would be appreciated!

• string parsing and substring in c

  - by Josh

  I'm trying to parse the string below in a good way so I can get the sub-string stringI-wantToGet: const char *str = "Hello \"FOO stringI-wantToGet BAR some other extra text"; str will vary in length but always same pattern - FOO and BAR What I had in mind was something like: const char *str = "Hello \"FOO stringI-wantToGet BAR some other extra text"; char *probe, *pointer; probe = str; while(probe != '\n'){ if(probe = strstr("\"FOO")!=NULL) probe++ else probe = ""; // Nulterm part if(pointer = strchr(probe, ' ')!=NULL) pointer = '\0'; // not sure here, I was planning to separate it with \0's } Any help will be appreciate it.

• UIImageView is clipping a pixel of the bottom of my UIImage...?

  - by akaii

  I'm not sure what might be causing this, but UIImageView occasionally clips off about a pixel or 2 from the bottom of some square/rectangular UIImages I'm using as subviews for UITableViewCells. These UIImageViews are well within the borders of the cell, so it shouldn't be due to cliptobounds. There seems to be no consistency or pattern to which images are being clipped, nor when they're clipped, other than that it only happens to (or is only noticable in) square/rectangular icons, and only ones that are parented to UITableViewCells (or their subclasses). I'm having trouble reproducing the problem consistently, which is why I haven't posted any code this time. Has anyone encountered something similar to this before? I've encountered a similar bug that involved floating point values for origin/size being interpreted weirdly... but that doesn't seem to be the cause of this particular problem. I don't need a specific solution at this point, I'm just making sure I haven't missed any well-known bugs or documented problems that involve UIImageView.

• Is there a tool to build and test a local change on multiple platforms

  - by Ben

  A company I used to work for was plagued with build breakages. So they made a tool that would zip up a developers local changes (which it detected from SCM) and send them to a remote server for a test build. The remote server would update its copy of the source with the repository and then apply the changes it received from the developer. It would then build and test the changes. We actually targeted multiple platforms so it would do the above for each of those platforms. When it was done, if everything was green, the developer was reasonable confident they could submit the change without breaking the "real" build. Are there any tools out there that do something similar?

• Zend_Form and Liskov Substitution Principle

  - by blockhead

  A very common pattern I see (I'm picking on Zend Framework, only because I was dealing with it at the moment of this question), is something like this: class My_Form extends Zend_Form { public function init() { $this->addElement(); } } Zend_Form is not an abstract class, but is perfectly usable on its own. This seems to be "recommended" as place to "encapsulate" your forms into a nice class. Does this violate the Liskov Substitution Principle? Each subclass of Zend_Form will have a wildy different behavior than the base class. Would it be better to use composition for this, or am I totally misunderstanding this principle?

• SVN: authz directory identifiers not support

  - by ledy

  Without using the authz, all the svn users can login and use the repos without issues. However, I would like to limit the access to some directories - not to be readable or writeable for all users. svnserve --version = 1.6.6 I tried both, granting access to users and groups. I also tried it separate, only group or only user access. [groups] admingroup=i_can_access_anything limitedgroup=i_am_limited [/] #*= @admingroup=rw i_can_access_anything=rw [projectX] #i also tried [repository:/projectX] #*= @limitedgroup=rw i_am_limited=rw Trying to access the / or /projectX at the svn fails. = access denied Without the authz, it works properly, but also grants access to other projects that do not belong to the "limited" user group :-/ Do you see what's wrong there? Thx

• .classpath and .project - check into version control or not?

  - by amarillion

  I'm running an open source java project that consists of multiple modules in a tree of dependencies. All those modules are subdirectories in a subversion repository. For newcomers to our project, it's a lot of work to set all that up manually in eclipse. Not all our developers use eclipse. Nevertheless, we're considering to just check in the .classpath and .project files to help newcomers to get started. Is this a good idea? Or would that lead to constant conflicts in those files? Is there an alternative way to make the project easy to set up on eclipse?

• How do I store in subversion my customizations to a public open source project?

  - by Clyde

  Hi, I'm working on customizing a couple of open source projects in ways that are very much personalized -- i.e., not appropriate to send the patches back to the maintainers for the public. One of them is stored in CVS, one in SVN. I use SVN for my own work. The CVS project is fine. I check the tree in to my svn repository, including the CVS directories. I can commit all my changes, and still do a cvs update to stay up to date with bug fixes/features of the public project. How should I work on the svn project? Is there a 'best practice' or known procedure for this kind of scenario?

• Using mercurial for web-design version control (dealing with images)

  - by Acorn

  I'm very new to Version Control, and I was wondering if I could get some advice on how it can fit into website design. At the moment I'm working on a typical, simple website that includes images: A few .html files and a .css file One folder full of photographs Another folder with the corresponding thumbnails Can I just put the whole lot in a repository? Or is there a better way I could apply Version Control to it? How should I deal with the images? edit: How well will it work with changes to the images? What if I decide to try and optimise my photographs or resize them. I wont be able to see what exactly changed about the images, should comments be enough to keep track of that?

• Convert SVN Subdirectory to Git

  - by magneticMonster

  I would like to ditch SVN for Git. My current SVN repository setup has projects under trunk (/trunk/projecta, /trunk/projectb, etc. with tags and branches at /tags/projecta-1.0, etc.). I would like to create distinct Git repos for each of these projects by pulling them out of SVN using git-svn. I've successfully pulled the entire SVN repo down to a local Git repo but all of the projects exist in the same Git repo now. Is it possible to pull them apart at this point?

• regular expression and escaping

  - by pstanton

  Sorry if this has been asked, my search brought up many off topic posts. I'm trying to convert wildcards from a user defined search string (wildcard is "*") to postgresql like wildcard "%". I'd like to handle escaping so that "%" => "\%" and "\*" => "*" I know i could replace \* with something else prior to replacing * and then swap it back, but i'd prefer not to and instead only convert * using a pattern that selects it when not proceeded by \. String convertWildcard(String like) { like = like.replaceAll("%", "\\%"); like = like.replaceAll("\\*", "%"); return like; } Assert.assertEquals("%", convertWildcard("*")); Assert.assertEquals("\%", convertWildcard("%")); Assert.assertEquals("*", convertWildcard("\*")); // FAIL Assert.assertEquals("a%b", convertWildcard("a*b")); Assert.assertEquals("a\%b", convertWildcard("a%b")); Assert.assertEquals("a*b", convertWildcard("a\*b")); // FAIL ideas welcome.
