Visual Studio 2015 with github plugin issue - github

I'm new to using github with visual studio 2015 plugin and I'm stuck.
I created a new project on github and was able to link the depot to my visual studio project. I was able to sync some code up to the depot.
Then I added a readme file to my project on github from the website. Next day I made more code and decided to sync it up to the depot, but now it says that I have incoming commits (the readme file). I clicked on fetch on the incoming commit but nothing happens. I clicked on pull and it says my changes would be overwritten by merge.
I then went to outgoing commit (the ones i just made) and click on push. it says that "You cannot push branch master to remote origin because there are new commits in the remote repository’s branch. Pushing this branch would result in a non-fast-forward update on the branch in the remote repository"
i click on several things and i still can't resolve this issue. I want to update my current project with the readme and then update my depot. (i also am new to the terminology)

The trouble is that you've got changes on the server, that are committed, and changes to some of the same files on your local copy that conflict with it to the extent that Git can't figure out which ones should "win".
You'll have to look at each file that has conflicts, understand where the conflicts are, sort them out, tell git that you've sorted out the file, and then progress.
So Fetch will bring all of the changes down from github, locally, but not change your working copy.
Merge is intended to pull down the changes in your current branch and merge them in (and that's where it's having trouble).
Best recommendation for working with git (whether Visual Studio or not)): Fetch and merge often. Every day at least.
This page looks like a reasonable tutorial on how to do it. It looks similar to my VS2015 git plugins.
https://msdn.microsoft.com/en-us/library/dd286559.aspx
This page is quite a good tutorial on doing it from the command line:
https://easyengine.io/tutorials/git/git-resolve-merge-conflicts/
(But I've got to say: the Visual Studio tool makes it easier).
So the key points are:
look at each file and fix the conflicts.
tell git that you've fixed the file
Once you've done all the files, you need to "commit the merge"
Then you're in a place to commit your local changes and push them up to the server.
Second tip: Most people that I know who use git with visual studio also use the command line client extensively, and usually have an additional gui client (such as Atlassian's Sourcetree) as well. I use all three every day.

How to correct «unable to merge unrelated histories»?

I use github desktop (https://desktop.github.com ) while developing the application with several other people, so, for some reason, when trying to merge two branches into one, the error "unable to merge unrelated histories" is displayed for one of the target branches.
What could be the problem?
First of all: You may also be able to find a solution using the search.
Potential reasons for the error message
From: https://komodor.com/learn/how-to-fix-fatal-refusing-to-merge-unrelated-histories-error
Here are some common scenarios where fatal: refusing to merge unrelated histories can occur.
You have a new Git repository with some commits. You then try to pull from an existing remote repo. The merge becomes incompatible because the histories for branch and remote pull are different. Git sees the situation as you trying to merge two completely unrelated branches, and it doesn’t know what to do.
There’s something wrong with the .git directory. It may have been accidentally deleted at some point or got corrupted. This can happen if you’ve cloned or cleaned a project. Here the error occurs because Git doesn’t have the necessary information about your local project’s history.
The branches are at different HEAD positions when you try to push or pull data from a remote repo and cannot be matched due to a lack of commonality.
Options to resolve the issue
The article describes two options on how to resolve/avoid such issues but targets command line /terminal users. I guess I would prefer option 2 over option 1 anyway, also using git in the terminal.
The article explains it like this:
The alternative (and longer) way of fixing refusing to merge unrelated histories issues is to unstage your current commits, stash them, clone your required remote repository, and then place your stashed branch contents into the new clone. This will ensure that any conflicts that you may encounter in the code are addressed before merging and prevent application errors from occurring.
How it (should) work in GitHub Desktop
In GitHub Desktop you should be able to use a modified version of option 2:
To unstage all the files in your last commit, double click staged files. This moves them to the unstaged area. Learn more in this GitHub issue.
To stash your unsaved files, right-click an unstaged file. Learn more about stashing files.
This will give you a clean working tree to pull your remote repository into. Once you’ve successfully pulled into your branch, you can:
unstash your files (see link above again) to reapply them to your current working copy.
commit them as a separate commit.
resolve any file conflicts that you may have.
I hope this explanation adds some clarity. Let me know if there are any wrong or misleading information in my text please.
This problem has several reasons.
But probably your project clone just differs from GitHub (main project).
First of all, save your project (because you probably don't want to code everything again).
Remove repo from GitHub desktop (not GitHub!!!)
Go to the project page in GitHub
Click code, open with GitHub Desktop, and code again.

How to merge deleted/changed file in eGit

The case:
Locally, I have a commit where I have deleted a file. Remotely, someone else have changed this file.
Now, when I merge, I find that git has the put the changed file in my working tree. This is probably the way git works, and in git command line, I'd be able to use git mergetool to choose between the deleted or changed file.
In eGit, however, how would I make this choice?
We ended up with a quite unusable work-around where we first addded the file to the index and then deleted it in working tree and then saved this change (deletion) to the index.
Technical info:
The version of eGit (feature) we're using is 4.9.2.201712150930-r.
The version of git we're using is 2.16.1
Background:
My team have recently moved to using Git as our revision control system. There's a general wish from team members to use an integrated solution and since we're working with Eclipse, eGit seemed to be the way to go.
I would suggest that all your team members follow this process:
Commit your changes to your local repository.
Pull with rebase to merge with the remote origin branch.
Resolve the conflicts, if any. In your case, if you deleted the file before the other team member modified it, then that person would have noticed that the file has been deleted.
Push the commit upstream.
This process has worked for us. Hope this helps.

Comments in git (egit)

We recently moved to git from svn (both using Eclipse). I am in the (perhaps bad) habit of writing my Java code first, getting everything to work and then going back and adding comments. In SVN this was easy. I would just create a Fisheye review with my Jira task. The review would have a list of all the files I changed and methods I added or modified. I would note it and abandon the review. Then I would edit all the files listed and add the comments.
However, Fisheye does not (I believe) work with git. I could do a git status to see the files I changed but the local branch is already updated so it will not list any files. And all it does is tell me I am something like one commit ahead of the remote branch but does not list any files.
Is there some way to see a lit of the files I have changed with git so I can add comments? And when I say I wait for my comments I really mean mostly for added classes and methods. If I do something like add a line or two to a method I will generally add the comment too.
changing comments on git commits is not that easy. Each git commit has a sha-checksum which also includes the previous git commit. If you change a commit you change the current commits sha-checksum. therefore you create a new commit. All following commits of your branch must now be rebased on top of this new commit.
The command line provides the git rebase -i [commitid] where you can do lots of modifications including changing comments on commits. I never did this with a GUI but egit might support that too. Just refer documentation on egits rebase feature.
I found out how to do this.
The "Synchronize Workspace" in eclipse appears to show all the changed files not yet pushed remotely. I have not done any pushes, so this showed me what files changed.

How to view file changes before pulling through GitHub on RStudio?

I'm transitioning from using Subversion in Eclipse for code management to GitHub in RStudio. It's starting to make sense, but I can't seem to figure out how to pull effectively.
Specifically, if I use the Pull arrow in RStudio, every file change in the repository automatically updates my local files without warning. I can see how many files were updated, but not what changed!
Here are the questions I'm hoping to get help with:
1) Can I preview the repository file changes in RStudio before I pull them locally? With SVN in Eclipse, there was an indicator showing files with a difference, and the option to view side by side.
2) If multiple files have been changed on the repository, is it possible to pull just 1 locally?
3) How can I revert a local file to a previous version?
Right now I've been trying to do this all within RStudio for simplicity. I haven't used things like the GitHub desktop client.
I appreciate the help!
I would suggest you better get used to the git's own tools to stay informed about your repository.
For example you could do following.
Before you pull, check your current commit logs
git log
This should show you how your current commits stack up. Note the latest commit id (first 4-5 letters would usually do)
Now after pulling you can see the difference using following command
git diff --color your_previous_commit_id..HEAD
If you don't like the changes and want to go back,
you can just reset to your favorite commit with following command. BTW run "git stash save" to keep a copy of your uncommitted changes.
git reset --hard you_favorite_commit_id
Note: that this will delete all your uncommitted changes unless you stashed them and put your local branch behind the remote repo branch you are tracking again.
Wondering where to put these commands? Check https://git-scm.com/downloads.
What's good about using these git tools is that if you switch between IDEs you don't need to search for same functionalities you had in your earlier IDEs.

GitHub client cannot sync after changes made to some files

I have a git repository in which I work in collaboration with some people but I cannot sync anymore. I am using the GitHub Windows client application on Windows 7:
Last time I synced, the operation succeeded and I ended up with a perfect copy of the latest code.
Next, I made some simple changes to a few files, but did not commit anything yet.
In the meantime, someone else made changes to some other files.
In order to see the changes of the repository, I'm trying to sync again.
GitHub client reports "Sync failed".
Now I am wondering if this is normal behavior or if there is something wrong with my repository ? Shouldn't I be able to sync the repository and get latest files even though I am making some changes that are still not committed ?
Thanks.
When you got this kind of error just try to open a git shell and type git status into your working directory. You will have some infos that could help you like which files are in conflict.
It must be one of the other collaborators that updated and pushed a file you just updated. If so, you will have to choose which version you want to keep in your local files.
