Bare Git repo cannot add files or commit files - linux

So I have been plagued with this weird git problem that myself and a few other developers have not been able to solve. Here it is:
I created a bare repo for managing website changes using git on test server.
For this example the repo is here: /home/website/website.git
The website public root would be here: /home/website
I created the repo by doing this command: git init --bare
inside the git repo directory "website.git"
Next I have my local repo on a machine elsewhere. This is a standard git repo. I build the site get it ready to deploy. When its ready I push it to the bare repo. From my local repo.
There is a post-receive hook that checks the latest file tree out into the public root of the website. So when I change things on the local repo and test them in the localhost environment, once satisfied I can push them to the live server.
Here is the problem I face:
I can push fine. No issues. All works as expected. Code gets checked out to public root. Everybody is happy and goes on with their life.
BUT!!!:
The site is a CMS site. Users log in to it and upload things. Files get created on the public root of the website which is the GIT_WORK_TREE.
So NBD right?! I can just commit the files every now and then from the live bare repo and pull them back to my local environment like I have before. So I log into SSH on the server. Navigate to /home/website/website.git
Then run this command:
GIT_WORK_TREE=/home/website/ git add ../
I get this mess:
error: unable to create temporary sha1 filename ./objects/cb: No such file or directory
error: error_log: failed to insert into database
error: unable to index file error_log
fatal: adding files failed
I have done this before on other servers and it worked fine from what I remember. So I was like WTF, must be something strange on this server. I went to another server I have and replicated the EXACT same steps. Got the EXACT same problem. So now I fear I am loosing my sanity and maybe these previous git experiences are all made up in my head.... *Well, lets not go that far yet.... :)
Maybe somebody can help me out here. I have used git plenty and can't seem to crack this one.
Oh, some other maybe useful specs:
running CENTOS 6.2
I double checked all permissions. I even tried changing everything to 777 recursively just to make sure Im not loosing it somehow. Made sure all the files are owned by the correct user. chowned recursively. I also tried the standard solution to this problem which is described here: https://answers.atlassian.com/questions/132671/git-commit-fails-with-sourcetree-error-unable-to-create-temporary-sha1-filename-git-objects-d8-file-exists
That didnt work either. Not sure where to go from here.
PLEASE HELP ME!!!!
I feel like Linus is playing cruel tricks on me right now.

You have a bare git repository in /home/website/website.git which is inside of a git repository in /home/website? And then you try to trick the bare git repository into having a working tree using GIT_WORK_TREE?
Maybe it is worth understanding this setup but only if you intend to be a git developer. As you are a user focused on delivering website functionality, I suggest using a standard git setup.
Move the bare git repository elsewhere:
$ mkdir /home/repo
$ mv /home/website/website.git /home/repo/website.git
$ cd /home/website
$ git remote set-url origin /home/repo/website.git

I got the solution. This is it. I was running the above command from the git repo.
Turns out the command should be run from the work tree and altered to look like this:
GIT_WORK_TREE=/home/website/ git --git-dir="./website.git/" add ./

Git Update Files on Repo Change

I have a VPS running a Node.js / React app.
I want to update the files in the vps each time I push data to the git(hub).
I found out, using this answer, that I can add some hooks in git, executing commands on "post-receive".
What I didn't quite understand :
Why did he init another git ? Couldn't he have done this in the .git directory and create the hooks/post-receive file?
Why git checkout -f ? If the goal is to update local files, so nodemon / create-react-app restarts the server / app, why not execute a git pull instead ?
Is there a better way of doing this ?
In the recommended answer there, nobody is using GitHub and there is no other Git repository yet. So the answer to your question:
Couldn't he have done this in the .git directory and create the hooks/post-receive file?
is: No, there was no .git directory in the first place. The target machine had nothing at all, no Git repository, no working tree, etc. The git init --bare created the Git repository (the ".git directory").
The git checkout -f is a poor-man's / low-quality implementation of push to deploy. A receiving repository is normally "bare", and this one is no exception.
why not execute a git pull instead ?
That would require creating a third Git repository. That would have been an option.
"Better" is in the eye of the beholder. There are many ways of doing this, each with its own pluses and minuses. See also Deploy a project using Git push, which notes that since Git 2.3, receive.denyCurrentBranch = updateInstead is available; it was not available prior to 2015 (and in 2015, many people had older versions of Git installed).
Note further that if you're using GitHub as a hosting system, this changes a number of variables. The questions and answers you and I have linked here are aimed at those not using GitHub.

How can I determine the URL my git repo is located?

I am to work on a project and I have initialized a git repo on a server. Let's suppose the URL of the server is
foo.bar
and the repo is at
/var/www/vhosts/foo.bar/httpdocs
I have created a git repo by running
git init
and then I created a .gitignore file, added whatever needed to be added, committed and from my local computer, which has ssh access to the server I have attempted to clone the repo, but I do not seem to find the correct URL or something is not set for the repo. I tried something like:
git clone https://foo.bar/httpdocs/.git
The error was
fatal: repository 'https://foo.bar/httpdocs/.git' not found
I have tried with various pathes.
FYI: I have worked with git a lot in the past, but I have never set up a repository on a server, I have always received the path of repos created by someone else. Now I have created the repo, but I cannot seem to find out what the correct URL is. I have searched a lot to find this out, but unfortunately I did not find anything which would help me. Any ideas?
If you're trying to communicate via SSH, you need the SSH link, not the HTTP(S) link:
git clone <user>#foo.bar:/var/www/vhost/foo.bar/httpdocs/.git
You need git and sshd (or openssh-server) installed on the remote server, and add your SSH key to the server, under the correct user (with ssh-copy-id, of course).
This is pramar error.
The error is in line:
cit clone https://foo.bar/httpdocs/.git
you can try:
git clone https://foo.bar/httpdocs/.git
good luck.

Permissions Issue When Pulling from GitHub

I have cloned a GitHub repository into a new directory on my local machine using:
git clone git#github.com:*****/project.git destination-dir
Clone worked fine but whenever I try to pull or push I git this error back:
error: insufficient permission for adding an object to repository database .git/objects
fatal: git write-tree failed to write a tree
What have I done wrong? And how can I fix this. From what I read so far online, the problem is trivial if you are using your own repository (i.e. not GitHub) but what should I do if this on GitHub (there is no ssh access).
Also, I should add that I have another directory on my machine pointing to same repository on GitHub which is fine for pulls and push.
This doesn't look like related to GitHub per-se.
From what you say in the comments, it seems that the write permissions inside the hidden .git folder (which contains all of your local git repository data) were not corresponding to the permissions that your git client had when you ran it.
It can be that you cloned the repository with one user account (or using sudo), but where trying to pull/push from a different user. If that wasn't the case, something could have messed your local files permissions while cloning.
As you stated, doing chown -R login:group projectDir/ fixed the problem because it recursively reset all permissions in your project folder (including those of the .git folder and its contents).
A good experiment would be trying to clone the same repo to a different folder to see if the problem reoccurs. If it does, maybe something is wrong with your default permission usermask and/or your git client permissions.

How could I recover my git-daemon repositories

I had a Gitorious install that got old and it is clear now that it is not coming back. I want to recover the repos (mainly the wiki repos) from the repository. I do not want to repeat the long and painful process of setting up Gitorious again, just to get some wiki back out of it...in fact I'd like to clean up the old install soon (remove it). Although, when it was running it was awesome!
I still have the database for gitorious, so I know which .git files I want and where to find them.
I was attempting to setup git-daemon (I'm on a Linux (ubuntu) setup), but I am not having much luck. I was hopeful that maybe I could just copy the 'foo.git' file somewhere and clone it.
Currently my .git files are in user git's home folder. No problem moving them though, but I'm not sure how to go about this.
I have git daemon running, but it 'hangs up unexpectedly' if I try to connect via 'localhost', all the repos also have my 'export-ok' file in them too. I can connect accross my LAN and clone any other git initialized directory via ssh, could that help me?
Can I just copy the foo.git (more like a f13f9ed412591ce72f7b3cb793605e93ce.git) file to maybe a git initialized repo and work with it there? Is there a git tool that I could use to expand the .git file? <-- I'm sure Git would be the tool right?
The .git is a folder and not a file and git repos are lightweight in that it is just files and folders. You can copy your repo to wherever you want.
Since you said localhost, if you want you can even clone the repos with git clone /path/to/repo.git and work on the cloned repo. You do not need the daemon or anything else to be running.

gitolite hook for specific repository

I don't understand how do I create a post-receive hook for a specific repository in gitolite (non-root install)
My bare repository contains a website that should copy the working directory to the docRoot
(GIT_WORK_TREE=/path/htdocs git checkout -f) on update
Before gitolite, I would just update the hook for the specific repository.
Gitolite documentation mentions that all hooks should be at hooks/common so I don't understand how it works.
What should be the name of hooks, where it should be located and how it's structure should be changed (if it should)?
Update July 2013: what follows is for gitolite V2 (or 'g2'), which was the version used by the OP at the time (November 2011).
Update August 2013, with the latest gitolite 3.x:
You now have official specific repo hook:
it's basically just creating a symlink in <repo.git>/hooks pointing to some file inside $rc{LOCAL_CODE}/hooks/repo-specific (except the gitolite-admin repo)
All hooks in gitolite/hooks/common are replicated in all repositories managed by Gitolite, as detailed in the hook propagation documentation.
That means your hook script must take specific action depending on the repo which execute said hook.
You can either use the $GL_REPO variable (which gitolite set and pass to all its scripts for any git command it receives).
Or you can use some git configuration registered on the gitolite server, like the mirroring hook does. See the post-receive.mirrorpush hook.
The OP Eyal R adds in the comments:
But I still don't understand how it is done (I understand that $GL_REPO is used to determine which repo I am updating but I'm missing the practical part).
I have created a file called post-receive.test with echo "test", put it in $HOME/gitolite/hooks/common, ran gl-setup, ran push from workstation - nothing happens (no "test" output)
To which I replied:
The hook should appear in the hook directory of your repo on the gitolite server as a link, linking back to the .gitolite/common/hook. Note that it should be in $HOME/.gitolite/common/hook, not /gitolite.
The OP confirms the missing dot was the issue.
The process to add an hook is detailed in Hook propagation in gitolite, and their usage in "Using Hooks".
This is a fairly common need for someone using gitolite, and appears to be a little difficult to tie up loose ends when being not a very advanced user (at leas it was for me).
Following stackoverflow's and gitolite's links back and forth can be a little confusing. These are my conclusions and the path I followed to be able to achieve this.
As #VonC mentioned creating repository specific hooks is already possible since version 3.5.3.1 (github link)
Update/Upgrade Gitolite
The first thing you should do is update your gitolite repo. So ssh into your server that is hosting gitolite and move to the location where gitolite is installed (usually /home/git/gitolite) as the git user (usually git)
Example:
$ ssh myusername#devserver.com
$ sudo su - git
$ pwd
/home/git
$ cd gitolite
Then we have to upgrade gitolite. To do so, first we need to update the gitolite repository
$ git pull
Then we have to repeat the install command (make sure you use the same arguments as before)
$ ./install
And finally run the setup again.
$ gitolite setup
If that doesn't work, you probably haven't set up gitolite executable in your PATH, so you could do something like this:
$ src/gitolite setup
Gitolite Settings (The "RC" file)
This was one of the parts that confused me the most, but it ended up it was pretty straight forward.
The famous "rc" file is located at git's home directory /home/git/.gitolite.rc. There make sure you have a variable called LOCAL_CODE, you should see something like this on that file, if not, add it.
LOCAL_CODE => "$ENV{HOME}/.gitolite/local"
And in the "commands an feature to enable" section you should make sure that repo-specific-hooks is available, if not, add it.
ENABLE => [
# COMMANDS
# These are the commands enabled by default
'help',
'desc',
'info',
...,
...,
...,
'repo-specific-hooks'
...,
...,
...
]
Here is the link to the documentation
Writing Repository Specific Hooks
Finally, in your local gitolite-admin repository create the following directories hooks/repo-specific under the directory you just set in the LOCAL_CODE variable, for example:
gitolite_admin/local/hooks/repo-specific
After that you can actually add your hooks scripts to that location and manage them through the gitolite conf file as stated in the documentation. Make sure the scripts are executable.
repo foo
RW+ = #all
option hook.post-receive = deploy
Again, I hope this helps some of you guys.
Cheers!
