Storyboard got corrupted during a merge - objective-c

In Xcode we pulled someone else's push and merged with local copy. However now the pulled copy has corrupted storyboard. The worst thing is we accidentally pushed those corrupted file to remote repo. Now is there any way I can solve this issue?
we are using SourceTree as our interface to Git.
One of our member has the last working copy as we haven't pulled any corrupted data from server to his copy.
Any potential solution for this situation? Thanks

Sorry but I'm not enough of a Git expert be be able to give you the exact commands, but there are git commands you can enter to revert a file to a specific revision/commit. If you hunt around the web you should be able to find them and revert the file.
You may have to use command line Git.
This may help Reset or revert a specific file to a specific revision using Git?
and this Rollback file to much earlier version using Git

A pull and merge is commited to the history like any other change so you just need to undo that commit. The git command to delete the last commit and restore your working tree to the previous commit is:
git reset --hard HEAD~1
(from Delete commits from a branch in Git)
This change could then be pushed back up to your server.

How can I see commits that i upload?

I did some changes in my code and after that i did git-review. The changes were on the branch b1 and I created only one commit for these changes. And the changes still unmereged.
After some-days, I deleted this repo from my workspace, and i cloned this repo again.
I see the commit in gerrit, but I don't see on the branch, even after I did git pull --rebase.
What is the reason that I don't see my commit? And how can I fix that (so I will can see it) ?
If you don't see the commit on the branch I assume it's still on reviewing (it wasn't merged yet). In this case, if you want to see the commit locally in a new repository clone, you need to download the commit explicitly.
Go to your Gerrit server;
Go to the change page with your commit (which is on reviewing);
Click on "DOWNLOAD" (on the middle-right of the page);
Choose and copy one of the available commands to download the commit:
All commands will download the commit using different methods, I suggest using the "Checkout" one.
Execute the download command in your local repository.

IntelliJ: How to create a local Java project copy for backup?

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.

Make Xcode 5 follow history after git file rename

I am trying to figure out how to correctly rename files with git while using Xcode.
I made a test project, with a few commits, then renamed a file in Xcode, verified that the git status did say it was being renamed, and then committed outside of Xcode. This was in accordance with this answer to a SO question (Handling file renames in git).
I go back in to Xcode, try to look into the history of that file before the name change (in the version editor assistant window), and I get the error "This file does not exist in the index." While that is true, the file did not exist at that point, its predecessor did. When I go to the terminal, and run git log --follow myFile.m, I do see all commits, even those before the rename. So with that, the history is there, but Xcode doesn't seem to know how to find it.
How can you follow before a rename of a file in git version control when using Xcode?
PS. It does seem that the blame functionality can see before the name change, but the version editor can not.
I had the same error today and as suggested by matt
the best solution is to use an alternate Git GUI.
I finally solved this by installing the great GitX app by rowanj.
Then i saw the uncommitted change and simply commit it.
TY Xcode for being too git-simple and renaming-painful !

How to recover from an unwanted rename using git-svn: "Transaction is out of date"

I'm using git-svn. I've moved file 'A' to 'B' and I'm up to date with the svn HEAD (using git svn rebase). I can commit all other changes without problems. Now I've decided that I want to move 'B' back to 'A' and commit that change.
When I do the move and commit to my local master it works fine, but I get the following when doing a git svn dcommit:
Transaction is out of date: Out of date: 'A' in transaction '3652-1' at /opt/local/libexec/git-core/git-svn line 570
So I tried to copy and delete in a separate commit which resulted in:
Item already exists in filesystem: File already exists: filesystem '/usr/svn/db', transaction '3652-1', path 'A' at /opt/local/libexec/git-core/git-svn line 4735
I've recovered from this situation with plain svn by using the workarounds like the one described in the documentation, but I don't know how to recover with git-svn. What is going on and how do I fix it?
Removing .git/svn did not work for me. Instead, here's how I resolved:
Deleted the offending directories from the repository (But I'm not sure that this is necessary. In hindsight I think I could have skipped this step)
git svn rebase
During the rebase, there were some conflicts. For each conflict, I resolved the conflicts in text editor, then used git add <file-in-conflict> and then git rebase --continue
After rebase completed successfully, git svn dcommit ran successfully!
I can't claim to understand what's really going on under the hood in git-svn in this case (although the underlying SVN issue makes perfect sense). My usual strategy when git-svn gets confused somehow is to blow away the .git/svn metadata directory (as in this post). This almost always saves me from odd synchronization issues between the git and SVN repositories.
It happened with me when I interrupted the dcommit process.
Follow these steps to recover from error:
git svn rebase
You will get conflicts in files. Resolve the conflicts & then git add filename (in which conflict occurred) for each file.
Now do git svn dcommit. It will be pushed to remote successfully.

Tortoise SVN Repo-Browser

I was wondering if I right click on a file in the SVN repo browser, does it get permanently deleted? can it be recovered?
This question/answer from the SVN FAQ might interest you :
How do I completely remove a file from the repository's history?
There are special cases where you
might want to destroy all evidence of
a file or commit. (Perhaps somebody
accidentally committed a confidential
document.) This isn't so easy, because
Subversion is deliberately designed to
never lose information. Revisions are
immutable trees which build upon one
another. Removing a revision from
history would cause a domino effect,
creating chaos in all subsequent
revisions and possibly invalidating
all working copies.
The project has plans, however, to
someday implement an svnadmin obliterate command which would
accomplish the task of permanently
deleting information. (See issue 516.)
In the meantime, your only recourse is
to svnadmin dump your repository, then
pipe the dumpfile through
svndumpfilter (excluding the bad path)
into an svnadmin load command.
If it's that hard, there are little chances it can be done easily from Tortoise SVN...
(And it's not the goal of Source Control...)
You'll find that you can only delete from the Repo Browser when you are viewing the HEAD revision. This is identical to deleting a file from your working copy and then checking in the delete. In both cases, you'll be able to restore from the previous revision.
Deleting a file via the repo-browser context menu basically creates a new global revision where just that file was deleted, so it appears in the log as such - you can always revert to that revision to get the file back, or you can just pull it directly from the repository into your working copy.
No... Deleting a file (even using the repo browser) only affects working copies. It would be a pretty lousy revision control system if you couldn't recover a file from the past. It is actually pretty difficult to modify files in a committed revision, even if you have root access to the server.
Doesn't right-click just bring up some sort of menu? And with SVN is that you can always revert anyways.
I deleted a top level directory from Repo Browser by accident and the only way to get it back was the following:
Export the top level folder from a previous version history
Make a new folder in the repository to replace the one deleted.
Add the exported files back to the new directory (same name as previous)
Update the working copy, it will delete and then re-add the same files.
Its annoying but at least the working and repo will be back in sync. The "Revert Changes from this Revision" didnt work for undoing repo deletes, it only reverts in working directory not the "Undo" the delete to the repository.
