  • Are there any good examples of open source C# projects with a large number of refactorings?

    - by Arjen Kruithof
    I'm doing research into software evolution and C#/.NET, specifically on identifying refactorings from changesets, so I'm looking for a suitable (XP-like) project that may serve as a test subject for extracting refactorings from version control history. Which open source C# projects have undergone large (number of) refactorings? Criteria A suitable project has its change history publicly available, has compilable code at most commits and at least several refactorings applied in the past. It does not have to be well-known, and the code quality or number of bugs is irrelevant. Preferably the code is in a Git or SVN repository. The result of this research will be a tool that automatically creates informative, concise comments for a changeset. This should improve on the common development practice of just not leaving any comments at all. EDIT: As Peter argues, ideally all commit comments would be teleological (goal-oriented). Practically, if a comment is made at all it is often descriptive, merely a summary of the changes. Sadly we're a long way from automatically inferring developer intentions!

  • Is it possible for a good programmer to have never used version control?

    - by lortabac
    I am looking for an expert programmer to help solve a difficult situation. The interviews so far have been surprisingly disappointing. The best candidate so far is a very experienced programmer who has never used version control software. The problem in itself might not be too serious because it is something which can be learned in a short time. But there is a deeper aspect, which worries me: How is it possible to actively develop software for 10-15 years without ever needing version control? Is the fact itself of not looking for a solution to the problem of tracking changes a sign of a wrong attitude to programming?

  • Is it unusual for a small company (15 developers) not to use managed source/version control?

    - by LordScree
    It's not really a technical question, but there are several other questions here about source control and best practice. The company I work for (which will remain anonymous) uses a network share to host its source code and released code. It's the responsibility of the developer or manager to manually move source code to the correct folder depending on whether it's been released and what version it is and stuff. We have various spreadsheets dotted around where we record file names and versions and what's changed, and some teams also put details of different versions at the top of each file. Each team (2-3 teams) seems to do this differently within the company. As you can imagine, it's an organised mess - organised, because the "right people" know where their stuff is, but a mess because it's all different and it relies on people remembering what to do at any one time. One good thing is that everything is backed up on a nightly basis and kept indefinitely, so if mistakes are made, snapshots can be recovered. I've been trying to push for some kind of managed source control for a while, but I can't seem to get enough support for it within the company. My main arguments are: We're currently vulnerable; at any point someone could forget to do one of the many release actions we have to do, which could mean whole versions are not stored correctly. It could take hours or even days to piece a version back together if necessary We're developing new features along with bug fixes, and often have to delay the release of one or the other because some work has not been completed yet. We also have to force customers to take versions that include new features even if they just want a bug fix, because there's only really one version we're all working on We're experiencing problems with Visual Studio because multiple developers are using the same projects at the same time (not the same files, but it's still causing problems) There are only 15 developers, but we all do stuff differently; wouldn't it be better to have a standard company-wide approach we all have to follow? My questions are: Is it normal for a group of this size not to have source control? I have so far been given only vague reasons for not having source control - what reasons would you suggest could be valid for not implementing source control, given the information above? Are there any more reasons for source control that I could add to my arsenal? I'm asking mainly to get a feel for why I have had so much resistance, so please answer honestly. I'll give the answer to the person I believe has taken the most balanced approach and has answered all three questions. Thanks in advance

  • SQL version control methodology

    - by Tom H.
    There are several questions on SO about version control for SQL and lots of resources on the web, but I can't find something that quite covers what I'm trying to do. First off, I'm talking about a methodology here. I'm familiar with the various source control applications out there and I'm familiar with tools like Red Gate's SQL Compare, etc. and I know how to write an application to check things in and out of my source control system automatically. If there is a tool which would be particularly helpful in providing a whole new methodology or which have a useful and uncommon functionality then great, but for the tasks mentioned above I'm already set. The requirements that I'm trying to meet are: The database schema and look-up table data are versioned DML scripts for data fixes to larger tables are versioned A server can be promoted from version N to version N + X where X may not always be 1 Code isn't duplicated within the version control system - for example, if I add a column to a table I don't want to have to make sure that the change is in both a create script and an alter script The system needs to support multiple clients who are at various versions for the application (trying to get them all up to within 1 or 2 releases, but not there yet) Some organizations keep incremental change scripts in their version control and to get from version N to N + 3 you would have to run scripts for N-N+1 then N+1-N+2 then N+2-N+3. Some of these scripts can be repetitive (for example, a column is added but then later it is altered to change the data type). We're trying to avoid that repetitiveness since some of the client DBs can be very large, so these changes might take longer than necessary. Some organizations will simply keep a full database build script at each version level then use a tool like SQL Compare to bring a database up to one of those versions. The problem here is that intermixing DML scripts can be a problem. Imagine a scenario where I add a column, use a DML script to fill said column, then in a later version that column name is changed. Perhaps there is some hybrid solution? Maybe I'm just asking for too much? Any ideas or suggestions would be greatly appreciated though. If the moderators think that this would be more appropriate as a community wiki, please let me know. Thanks!

  • Bazaar merge identical files

    - by Kristopher Ives
    I have two Bazaar (bzr) repositories that have very similar content. I'm trying to identify the differences and incrementally synchronize. My current strategy is to bzr add files to both repos and then use bzr merge to identify and resolve conflicts. The problem is that even if the file contents are identical it creates a conflict and a .moved file. What can I do to stop these conflicts or use a better workflow?

  • How to have a PHP Website tool with a version check

    - by Sara
    Hi, So I work on a small php website tool that a few people use and what I'm looking to have added is a little version checker in it. The tool is normally hosted by others on different servers/domains/whatever have you so I'm having a bit of a trouble figuring out how I can accomplish this and do so in the best possible method. So what I'm looking to do is have a webpage that just has a number on it which is the latest version. Lets say 3.2.2 is displayed on www.myawesomephptool.com/version.html in some way shape or form . Now on their installation when they open up their admin page it pulls in that 3.2.2 as the latest version to see if they are on that version. So trying to keep it simple on requirements too. Thanks for any help or suggestions, Sara

  • Ignoring build number when referencing dll

    - by brickner
    I have one solution with a .NET 4.0 project (C#) that produces a delayed signed dll, that I dotfuscate and sign. EDIT: This is how I version the dll: [assembly: AssemblyVersion("0.7.0.*")] [assembly: AssemblyFileVersion("0.7.0.0")] I have another solution with a .NET 4.0 project (C++/CLI) that references the signed dll and produces a signed dll (actually, delayed signed and signed in a post build because of a flaw in the C++ build system). The problem is that the reference to the dll contains a specific version number, which includes even the build number (I want to have a build number). Every time I build the referenced dll, I have to change the project settings file (.vcxproj) so it reference the new version dll. Since I work with source control, this is very inconvenient (different computers might have different build numbers since each computer build its own referenced dll - the referenced dll is not in the source control). If I don't change the reference, I get a warning: warning MSB3245: Could not resolve this reference. Could not locate the assembly... And many errors like this: error C3083: 'Foo': the symbol to the left of a '::' must be a type These are resolved once I change the reference. How do I make the reference ignore the build number or even the entire version number?

  • Maximizing the number of true concurrent / parrallel http requests in Silverlight

    - by Clems
    Hi all. I'm using SL 4 beta and my app needs to do a lot of small http requests to the server. I believe that when exceeding the number of allowed concurrent requests, the subsequent requests are put in a queue. I am also aware that SL 4 has both a http browser stack and a http client stack, with both different limit in terms of the number of concurrent requests. Let's say call those limits MAX_BROWSER and MAX_CLIENT. Also I think I read somewhere that the number of concurrent requests is limited per domain, not overall. But I'm sure if this applies to both the http client stack. That means that you CAN have MAX_BROWSER requests to domain1.com AND MAX_BROWSER requests to domain2.com at the same time. And I even believe that sub domains are considered different so you can also have MAX_BROWSER requests to domain1.com AND MAX_BROWSER requests to sub.domain1.com at the same time. I have ownership of the services and domain names so I could easily setup sub domains for my services. Given those considerations I'm trying to optimize the number of concurrent http requests to my server. Here are few questions ? Is is possible to use both stack at the same time ? Is the subdomain/domain story true for both stacks ? None ? If so that would mean that I could potentially have a number of concurrent requests equal to : (MAX_BROWSER + MAX_CLIENT) * NUMBER_OF_DOMAINS which would be fairly good. Is this correct ? I'm kind of sharing my morning thoughts here, hoping somebody has experimented with those things. Thank you.

  • Probability Random Number Generator

    - by Excl
    Let's say I'm writing a simple luck game - each player presses Enter and the game assign him a random number between 1-6. Just like a cube. At the end of the game, the player with the highest number wins. Now, let's say I'm a cheater. I want to write the game so player #1 (which will be me) has a probability of 90% to get six, and 2% to get each of the rest numbers (1, 2, 3, 4, 5). So, how can I generate a number random, and set the probability for each number? Thanks.

  • Need a regular expression for an Irish phone number

    - by Eoghan O'Brien
    I need to validate an Irish phone number but I don't want to make it too user unfriendly, many people are used to writing there phone number with brackets wrapping their area code followed by 5 to 7 digits for their number, some add spaces between the area code or mobile operator. The format of Irish landline numbers is an area code of between 1 and 4 digits and a number of between 5 to 8 digits. e.g. (021) 9876543 (01)9876543 01 9876543 (0402)39385 I'm looking for a regular expression for Javascript/PHP. Thanks.

  • Determine phone number based on time zone?

    - by Zachary Burt
    I have a (potentially international) phone number. It may or may not have a country code prefix. Does anyone know of a database that will help me map phone number = time zone? I would even just like to map phone number = country, since I can probably create country = time zone by scraping existing data on the web. This is a more complicated problem than it looks; for example, how do I know if it's a US-based number -- e.g. is it a USA area code, or an international country calling code? Any language is fine; I can port it.

  • php, user-uploaded files, version control, and website deployment

    - by user151841
    I have a website that I regularly update the code to. I keep it in version control. When I want to deploy a new version of the site, I do an export and then symlink the served directory name to the directory of the deployment. There is a place where users can upload files, and I noticed once that, after I had deployed a new version, the user files were gone! Of course, I hadn't added them to the repository, and since the served site was from an export, they weren't uploaded into a version-controlled directory anyways. PHP doesn't yet have integrated svn functionality, so I couldn't do much programmatically to user uploaded files. My solution was to create an additional website, files.website.com, which sits in a parallel directory to the served website, and is served out of a directory that is under version control. That way they don't get obliterated when I do an upgrade to the website. From time to time, I manually add uploaded files to the svn project, deleted user-deleted ones, and commit the new version. I'm working on a shell script to run from cron to do this, but it isn't my forte, so it's on the backburner as it's not a pressing need. Is there a better way to do this?

  • La fondation Eclipse sort Eclipse Juno 3.8 /4.2, une double version de l'EDI riche en nouveautés

    La fondation Eclipse sort Eclipse Juno 3.8 /4.2 La fondation Eclipse vient de sortir la version Juno d'Eclipse. Une nouvelle version d'Eclipse est disponible. Elle porte le nom de Juno. Cette version est en fait une double version, puisque nous avons droit à la fois à la version 3.8 ainsi qu'à la version 4.2. Il faut savoir que la version 3.8 est la dernière "version" pour Eclipse 3.XX. Des versions de maintenance sont prévue pour la 3.8, mais aucune version majeure supérieure n'est prévue dans les 3.XX. Cela tient d'une volonté de la fondation Eclipse de basculer majoritairement sur les versions 4.XX. La version 4 (précédemment baptisé e4) d'Eclipse est en développement depuis 4 ans et const...

  • Which Version Control Systems support LDAP/AD users and groups

    - by Jason Irwin
    Does anyone know which of the big players (if any) support LDAP/AD users and groups for authentication AND database permissions? Specifically, I'm wondering if SVN, GIT, Mercurial etc. will allow users to login/connect based on AD permissions and also allow granular permissions to be applied to folders within the VC database based on groups within AD. So far my research has not shown this to be possible....

  • Need in obtaining a specific local telephone number [closed]

    - by Brett
    I am wanting a local phone number that I like. I have found one that I like. When I call the number that I want it says "this number has not been allocated" I have looked up and found the company that owns that number. How do I go about acquiring that number from the company. I spoke with someone who sells major phone packages and he said that if I signed up with them he could get the number for me. He said that there is a change of ownership form that the send to get the number. So I know it can be done. I am hoping that someone with industry specific knowledge in this area can guide me in getting this number.

  • Can't get sync with SVN to work to put a directory under version control

    - by Chamster
    I've created a directory on our SVN server and added a local directory with my project to it. It got uploaded and seems to be OK. However, I didn't get those cute green (or any others) icons on the file. So I clicked on the project's directory and used "checkout". That wasn't good because I've downloaded ALL of the repository. How can I synchronize my uploaded directory with it's corresponding directory on the server? (It's probably something easy that I've forgot to check in or so...)

  • Finding a prime number after a given number

    How can I find the least prime number greater than a given number? For example, given 4, I need 5; given 7, I need 11. I would like to know some ideas on best algorithms to do this. One method that I thought of was generate primes numbers through the Sieve of Eratosthenes, and then find the prime after the given number.
