I am new to source control and I am confused with something I read on a webpage yesterday (I don't have the link). I have followed these instructions: "create folder structure", then "Start Reprobrowser", then copy source files into trunk folder. Please see the screen shot below:
However, when I navigate to the folder using Windows Explorer I do not see this folder structure. I see this:
Therefore I am wandering: where are the files physically stored? The reason I ask is because I want to ensure that NetBackup (corporate backup tool) backs up the correct directories.
To make sense of the repository structure you need to read all the documentation on SVN, but the preferred way to backup a SVN repository is through the command
svnadmin dump your_svn_repository_path > destination_filename_backup.svn
You could put this command in a scheduled task running sometime before your corporate tool execute the full backup of your data and include the destination_filename_backup.svn in your backup job
If you ever need to restore the backup (after recreating the repository) you could use the command
svnadmin load your_svn_repository_path < destination_filename_backup.svn

It's been 14 years since I last worked with svn and appearently I have forgotten everything...
I have an existing web-project, consisting of a bunch of php, html, js and other files in a directory tree on a V-Server. Now I want to take these folders under version control and create a copy on my local machine using svn. So I installed subversion according to these instructions: https://www.linuxcloudvps.com/blog/how-to-install-svn-server-on-debian-9/
Using the already-present apache2.
But now I kinda hit a roadblock. If I try svnadmin create on the existing folder, it tells me that is is not empty and does nothing really. All the questions and answers I find here and elsewhere are either
a) focussing on an already existing folder on the local machine
b) assuming more prior knowledge than I have right now aka I don't understand them.
Is there a step-by-step guide for dummies anywhere on how to do this? Or can anyone tell me in laymans terms how to do this?
I can't believe this case never comes up or that it is really very complicated.
At the risk of failing to understand your exact needs, I think you can proceed as follows. I'll use this terms:
Code: it's the unversioned directory at V-Server where you currently have the bunch of php, html, js and other files
Repository: it's the first "special" directory you need to create in order to store your Subversion history and potentially share it with others. There must be one and there can only be one.
Working copy: it's the second "special" directory you need to create in order to work with your php, html, js... files once they are versioned and it'll be linked to a given path and revision of your repository. At a given time there can be zero, one or many of them.
Your code can become a working copy or not, that's up to you, but it can never become a repository:
$ svnadmin create /path/to/code
svnadmin: E200011: Repository creation failed
svnadmin: E200011: Could not create top-level directory
svnadmin: E200011: '/path/to/code' exists and is non-empty
Your repository requires an empty folder but it can be located anywhere you like, as long as you have access to it from the machine you're going to use in your daily work. Access means it's located in your PC (thus you use the file: protocol) or it's reachable through a server you've installed and configured (svn:, http: or https:).
$ svnadmin create /path/to/repo
$ 😎
Your working copies can be created wherever you need to work with your IDE. It can be an empty directory (the usual scenario) or a non-empty one. The checkout command retrieves your files from the repo and puts them in the working copy so, at a later stage, you're able to run a commit command to submit your new and changed files to the repository. As you can figure out it isn't a good idea to create a working copy in random directories because incoming files will mix with existing files. There's however a special situation when it can make sense: when the repository location is new and is still empty. In that case you can choose between two approaches:
If you want code to become a working copy, you can check out right into in and then make an initial commit to upload all files:
$ svn checkout file://path/to/repo /path/to/code
Checked out revision 0.
$ svn add /path/to/code --force
A code/index.php
$ svn commit /path/to/code -m "Import existing codebase"
$ Adding /path/to/code/index.php
$ Transmitting file data .done
$ Committing transaction...
$ Committed revision 1.
If you don't care about code once it's stored in the repository or you want your working copy elsewhere, you can import your files from code and create a working copy in a fresh directory:
$ svn import /path/to/code file://path/to/repo -m "Import existing codebase"
Adding code/index.php
Committing transaction...
Committed revision 1.
$ svn checkout file://path/to/repo fresh
A fresh/index.php
Checked out revision 1.
With the creators update out, I'd like to upgrade my Ubuntu instance to 16.04.
The recommended approach to upgrade (and I agree) is to remove and replace the instance with a clean installation. However I have some files and configurations I would like to keep and transfer to the new install. They suggest copying the files over to a Windows folder to backup the files and restore afterward. However, by putting the files there, it messes up all the permissions of everything.
I had already done the remove/replace on one of my machines and I found that trying to restore all the permissions on all the files was just not worth it and did another clean install and will be copying the contents of the file over instead. This will be an equally tedious solution to restore these files but it has to be done.
Is there an easier way to backup and restore my files and their permissions when doing this upgrade?
I have two more machines I would like to upgrade but do not want to go through this process again if it can be helped.
Just use linux way to backup your files with permission, such as getfacl/setfacl or tar -p
I'm new to JavaFX 8 and the IntelliJ IDE. I have a JavaFX8 project that works but not as I would like. I'd like to try another approach but the substantial changes may not work. I don't want to loose code I have working.
To save code I have working, I've been creating a new project and then locally copying all the folders(.idea, out, src) and files except .iml, of the working project into the appropriate folders in the new project with the newly generated .iml.
This always seems to work but is it proper procedure?
I'm not on a team of developers and have yet to learn Git/GitHub.
Please advise. Thanks.
Maybe you should learn how to use a Version Control System like Git, then you can create a project repository and have different branches for things you want to try out. Keeping the working code in your master branch will prevent you loosing your working code. Also, when using a vcs you can always revert to versions of your code that have been working. The IntelliJ Idea IDE has perfect support for working with all different types of version control systems. If you don't want to learn any forms of vcs then there is no other way to "backup" your working code.
Is it proper procedure? It's probably not how most people would go about achieving what you want to achieve but it's certainly workable. If you wanted to stick with that for simplicity now, I'd copy the whole directory structure, delete the .idea and .iml files, and then create a new project in IntelliJ on that clean copy: IntelliJ will automatically set up folder structure based on the existing source without you having to go through any additional manual setup.
If you're willing to experiment with the git route, to achieve the basics of what you want to achieve is not very complicated and I've written a small quick-start below. IntelliJ offers very good support for Git, and once your repository is created you can do everything you need from the IDE. I'm going to assume you're working on Windows, although the steps shouldn't be too far removed on other platforms.
Install Git
You can download and install Git from https://git-scm.com/download/win, which will install a command shell called Git Bash.
One-off setup for your project
Open up git bash and go into the directory containing your source. Rather than seeing separate drives as Windows does, Git Bash assumes there is a logical 'root' directory under which all your files are accessible. Your C: drive will be /c. To move around you can use cd to change directory (using / instead of ) and ls to list files instead of using dir.
Assuming your source code is in C:\projects\myproject:
cd /c/projects/myproject
git init
The second line above creates a git repository in that directory. This doesn't affect your code, it just creates a folder called .git that contains all of the book-keeping information.
You don't want to have every file under version control - in particular you don't want your build outputs. You need to set up a file in your project directory called .gitignore which tells git which files and directories should be ignored. As a starting point you can copy https://github.com/github/gitignore/blob/master/Java.gitignore and rename the file to .gitignore
Basic Commands and committing your initial version
There are a small number of basic commands:
git status
Running git status will tell you which files have been modified, which are not under version control, and which files have been added to the staging area to be committed next time.
git add path/to/file
This adds a file to the staging area waiting to be committed. You can add multiple files to the staging area before committing them in one go.
git commit -m "description of your change"
This commits all of the staged files as a new version, which the specified commit message.
If you go into your project directory, do a git status and check through the list to make sure there's nothing you don't want to have under version control, then you can do git add . to add everything to the staging area and git commit -m "Check in initial version of the source code" to commit it to the repository.
After you've committed, you can run
git log
To see a history of all of the changes. IntelliJ has a view that will show you the same thing.
Creating an experimental branch
This is where git shines; if you want to try something experimental you can create a branch of your project while allowing git to preserve the original version.
git checkout -b experiment1
Will create and switch to a branch called experiment1. You can delete, rename, move, rewrite and develop whatever you like on this branch. The changes you commit will be independent of your original working version.
You can switch back to your original version (preserving all of the changes you've committed on that branch) using:
git checkout master
Where master is just the name of the default branch created when you ran git init. The experimental version will still be there and can be switched to again using git checkout experiment1 or from IntelliJ using the branch selection in the bottom right corner of the status bar.
If you decide that the changes you've made in experiment1 are to become your new "good" version, you can merge them back into the master branch and repeat the cycle from there.
I am attempting to share a file that builds and populates an SQL database through git, but it won't create the DB on my team members' machines because the .mdf and .ldf files are located on my machine. How can I rectify this?
If you want to share a SQL script, you don't have to share the database with it!
What is generally done (best practice) is that you have the script needed to create the database (and eventually populate it with static/test data) in git, and then the user will launch that script to build the database.
git is here to keep track of your source code and the changes made to it, you shouldn't put in it any generated file, and .mdf / .ldf files are typically part of what should not be in your git. For generated files within your folder, there are ways to configure git to ignore them.
The value of git is to record differences between files, if you want to share your software, git is definitely not the good tool. Put those file on a shared folder (NAS), on dropbox, give them through an USB key or whatever.
However, if you really want to do this (bad idea), I guess you can add your files in your repository and either configure SQL Server to find them here or create a symbolic link.
I am a noob in these server related work. I am writing some PHP code in my local system and has been updating my repo in github regularly. Each time I want to test my application, I copy all the files from my local system onto my server through FTP and then do it. Now I want to know whether is there a way to automatically make the commits that I make to reflect in the files in the server. Is there a way to automatically make the server get the files from the repo periodically? (say, once everyday).
Can this be done other way, like when I make a push from my local machine, the repo gets updated and in turn the files on the server also get updated?
My Server Details: Apache 2.2.15, Architecture i686 with Linux Kernel 2.6.18-194.32.1.el5
In addition to cronjobs, you can use a post-receive hook: http://help.github.com/post-receive-hooks/
If you have cronjobs you can use them. First set up the repository on your server. Then you can set up the cronjob, choose a time in which it should be executed, and then in the cronjob execute the following command:
cd your/repository/folder; git pull master origin
Perhaps explore the git archive command, which you can use to get a zip file or similar of your code. You could then perhaps use a script to copy that to your (other) server?
git archive --format=zip --output=./src.zip HEAD
will create a zip file called src.zip from the HEAD of your repo

Do a "git export" (like "svn export")?
