+# Git annex
+
+> **Warning:** GitLab has [completely
+removed][deprecate-annex-issue] in GitLab 9.0 (2017/03/22).
+Read through the [migration guide from git-annex to git-lfs][guide].
+
+The biggest limitation of Git, compared to some older centralized version
+control systems, has been the maximum size of the repositories.
+
+The general recommendation is to not have Git repositories larger than 1GB to
+preserve performance. Although GitLab has no limit (some repositories in GitLab
+are over 50GB!), we subscribe to the advice to keep repositories as small as
+you can.
+
+Not being able to version control large binaries is a big problem for many
+larger organizations.
+Videos, photos, audio, compiled binaries and many other types of files are too
+large. As a workaround, people keep artwork-in-progress in a Dropbox folder and
+only check in the final result. This results in using outdated files, not
+having a complete history and increases the risk of losing work.
+
+This problem is solved in GitLab Enterprise Edition by integrating the
+[git-annex] application.
+
+`git-annex` allows managing large binaries with Git without checking the
+contents into Git.
+You check-in only a symlink that contains the SHA-1 of the large binary. If you
+need the large binary, you can sync it from the GitLab server over `rsync`, a
+very fast file copying tool.
+
+## GitLab git-annex Configuration
+
+`git-annex` is disabled by default in GitLab. Below you will find the
+configuration options required to enable it.
+
+### Requirements
+
+`git-annex` needs to be installed both on the server and the client side.
+
+For Debian-like systems (e.g., Debian, Ubuntu) this can be achieved by running:
+
+```
+sudo apt-get update && sudo apt-get install git-annex
+```
+
+For RedHat-like systems (e.g., CentOS, RHEL) this can be achieved by running:
+
+```
+sudo yum install epel-release && sudo yum install git-annex
+```
+
+### Configuration for Omnibus packages
+
+For omnibus-gitlab packages, only one configuration setting is needed.
+The Omnibus package will internally set the correct options in all locations.
+
+1.  In `/etc/gitlab/gitlab.rb` add the following line:
+
+    ```ruby
+    gitlab_shell['git_annex_enabled'] = true
+    ```
+
+1.  Save the file and [reconfigure GitLab][] for the changes to take effect.
+
+### Configuration for installations from source
+
+There are 2 settings to enable git-annex on your GitLab server.
+
+One is located in `config/gitlab.yml` of the GitLab repository and the other
+one is located in `config.yml` of gitlab-shell.
+
+1.  In `config/gitlab.yml` add or edit the following lines:
+
+    ```yaml
+    gitlab_shell:
+      git_annex_enabled: true
+    ```
+
+1.  In `config.yml` of gitlab-shell add or edit the following lines:
+
+    ```yaml
+    git_annex_enabled: true
+    ```
+
+1.  Save the files and [restart GitLab][] for the changes to take effect.
+
+## Using GitLab git-annex
+
+> **Note:**
+> Your Git remotes must be using the SSH protocol, not HTTP(S).
+
+Here is an example workflow of uploading a very large file and then checking it
+into your Git repository:
+
+```bash
+git clone git@example.com:group/project.git
+
+git annex init 'My Laptop'       # initialize the annex project and give an optional description
+cp ~/tmp/debian.iso ./           # copy a large file into the current directory
+git annex add debian.iso         # add the large file to git annex
+git commit -am "Add Debian iso"  # commit the file metadata
+git annex sync --content         # sync the Git repo and large file to the GitLab server
+```
+
+The output should look like this:
+
+```
+commit
+On branch master
+Your branch is ahead of 'origin/master' by 1 commit.
+  (use "git push" to publish your local commits)
+nothing to commit, working tree clean

+To example.com:group/project.git
+ * [new branch]      git-annex -> synced/git-annex
+ * [new branch]      master -> synced/master
+ok
+```
+
+Your files can be found in the `master` branch, but you'll notice that there
+are more branches created by the `annex sync` command.
+
+Git Annex will also create a new directory at `.git/annex/` and will record the
+tracked files in the `.git/config` file. The files you assign to be tracked
+with `git-annex` will not affect the existing `.git/config` records. The files
+are turned into symbolic links that point to data in `.git/annex/objects/`.
+
+The `debian.iso` file in the example will contain the symbolic link:
+
+```
+.git/annex/objects/ZW/1k/SHA256E-s82701--6384039733b5035b559efd5a2e25a493ab6e09aabfd5162cc03f6f0ec238429d.png/SHA256E-s82701--6384039733b5035b559efd5a2e25a493ab6e09aabfd5162cc03f6f0ec238429d.iso
+```
+
+Use `git annex info` to retrieve the information about the local copy of your
+repository.
+
+---
+
+Downloading a single large file is also very simple:
+
+```bash
+git clone git@gitlab.example.com:group/project.git
+
+git annex sync             # sync Git branches but not the large file
+git annex get debian.iso   # download the large file
+```
+
+To download all files:
+
+```bash
+git clone git@gitlab.example.com:group/project.git
+
+git annex sync --content  # sync Git branches and download all the large files
+```
+
+By using `git-annex` without GitLab, anyone that can access the server can also
+access the files of all projects, but GitLab Annex ensures that you can only
+access files of projects you have access to (developer, maintainer, or owner role).
+
+## How it works
+
+Internally GitLab uses [GitLab Shell] to handle SSH access and this was a great
+integration point for `git-annex`.
+There is a setting in gitlab-shell so you can disable GitLab Annex support
+if you want to.
+
+## Troubleshooting tips
+
+Differences in version of `git-annex` on the GitLab server and on local machines
+can cause `git-annex` to raise unpredicted warnings and errors.
+
+Consult the [Annex upgrade page][annex-upgrade] for more information about
+the differences between versions. You can find out which version is installed
+on your server by navigating to <https://pkgs.org/download/git-annex> and
+searching for your distribution.
+
+Although there is no general guide for `git-annex` errors, there are a few tips
+on how to go around the warnings.
+
+### git-annex-shell: Not a git-annex or gcrypt repository.
+
+This warning can appear on the initial `git annex sync --content` and is caused
+by differences in `git-annex-shell`. You can read more about it
+[in this git-annex issue][issue].
+
+One important thing to note is that despite the warning, the `sync` succeeds
+and the files are pushed to the GitLab repository.
+
+If you get hit by this, you can run the following command inside the repository
+that the warning was raised:
+
+```
+git config remote.origin.annex-ignore false
+```
+
+Consecutive runs of `git annex sync --content` **should not** produce this
+warning and the output should look like this:
+
+```
+commit  ok
+pull origin
+ok
+pull origin
+ok
+push origin
+```

+# Issue Weight **[STARTER]**

+> in [GitLab Starter](https://about.gitlab.com/pricing/) 8.3.
+
+When you have a lot of issues, it can be hard to get an overview.
+By adding a weight to each issue, you can get a better idea of how much time,
+value or complexity a given issue has or will cost.
+
+You can set the weight of an issue during its creation, by simply changing the
+value in the dropdown menu. You can set it to a non-negative integer
+value from 0, 1, 2, and so on. (The database stores a 4-byte value, so the 
+upper bound is essentially limitless).
+You can remove weight from an issue
+as well.
+
+This value will appear on the right sidebar of an individual issue, as well as
+in the issues page next to a distinctive balance scale icon.
+
+As an added bonus, you can see the total sum of all issues on the milestone page.

+# Migration guide from Git Annex to Git LFS
+
+>**Note:**
+Git Annex support [has been removed][issue-remove-annex] in GitLab Enterprise
+Edition 9.0 (2017/03/22).
+
+Both [Git Annex][] and [Git LFS][] are tools to manage large files in Git.
+
+## History
+
+Git Annex [was introduced in GitLab Enterprise Edition 7.8][post-3], at a time
+where Git LFS didn't yet exist. A few months later, GitLab brought support for
+Git LFS in [GitLab 8.2][post-2] and is available for both Community and
+Enterprise editions.
+
+## Differences between Git Annex and Git LFS
+
+Some items below are general differences between the two protocols and some are
+ones that GitLab developed.
+
+- Git Annex works only through SSH, whereas Git LFS works both with SSH and HTTPS
+  (SSH support was added in GitLab 8.12).
+- Annex files are stored in a sub-directory of the normal repositories, whereas
+  LFS files are stored outside of the repositories in a place you can define.
+- Git Annex requires a more complex setup, but has much more options than Git
+  LFS. You can compare the commands each one offers by running `man git-annex`
+  and `man git-lfs`.
+- Annex files cannot be browsed directly in GitLab's interface, whereas LFS
+  files can.
+
+## Migration steps
+
+>**Note:**
+Since Git Annex files are stored in a sub-directory of the normal repositories
+(`.git/annex/objects`) and LFS files are stored outside of the repositories,
+they are not compatible as they are using a different scheme. Therefore, the
+migration has to be done manually per repository.
+
+There are basically two steps you need to take in order to migrate from Git
+Annex to Git LFS.
+
+### TL; DR
+
+If you know what you are doing and want to skip the reading, this is what you
+need to do (we assume you have [git-annex enabled][annex-gitlab-use] in your
+repository and that you have made backups in case something goes wrong).
+Fire up a terminal, navigate to your Git repository and:
+
+
+1. Disable `git-annex`:
+
+    ```bash
+    git annex sync --content
+    git annex direct
+    git annex uninit
+    git annex indirect
+    ```
+
+1. Enable `git-lfs`:
+
+    ```
+    git lfs install
+    git lfs track <files>
+    git add .
+    git commit -m "commit message"
+    git push
+    ```
+
+### Disabling Git Annex in your repo
+
+Before changing anything, make sure you have a backup of your repository first.
+There are a couple of ways to do that, but you can simply clone it to another
+local path and maybe push it to GitLab if you want a remote backup as well.
+Here you'll find a guide on
+[how to back up a **git-annex** repository to an external hard drive][bkp-ext-drive].
+
+Since Annex files are stored as objects with symlinks and cannot be directly
+modified, we need to first remove those symlinks.
+
+>**Note:**
+Make sure the you read about the [`direct` mode][annex-direct] as it contains
+useful information that may fit in your use case. Note that `annex direct` is
+deprecated in Git Annex version 6, so you may need to upgrade your repository
+if the server also has Git Annex 6 installed. Read more in the
+[Git Annex troubleshooting tips][annex-tips] section.
+
+1. Backup your repository
+
+    ```bash
+    cd repository
+    git annex sync --content
+    cd ..
+    git clone repository repository-backup
+    cd repository-backup
+    git annex get
+    cd ..
+    ```
+
+1. Use `annex direct`:
+
+    ```bash
+    cd repository
+    git annex direct
+    ```
+
+    The output should be similar to this:
+
+    ```bash
+    commit
+    On branch master
+    Your branch is up-to-date with 'origin/master'.
+    nothing to commit, working tree clean
+    ok
+    direct debian.iso ok
+    direct  ok
+    ```
+
+1. Disable Git Annex with [`annex uninit`][uninit]:
+
+    ```bash
+    git annex uninit
+    ```
+
+    The output should be similar to this:
+
+    ```bash
+    unannex debian.iso ok
+    Deleted branch git-annex (was 2534d2c).
+    ```
+
+    This will `unannex` every file in the repository, leaving the original files.
+
+1. Switch back to `indirect` mode:
+
+    ```bash
+    git annex indirect
+    ```
+
+    The output should be similar to this:
+
+    ```bash
+    (merging origin/git-annex into git-annex...)
+    (recording state in git...)
+    commit  (recording state in git...)
+
+    ok
+    (recording state in git...)
+    [master fac3194] commit before switching to indirect mode
+     1 file changed, 1 deletion(-)
+     delete mode 120000 alpine-virt-3.4.4-x86_64.iso
+    ok
+    indirect  ok
+    ok
+    ```
+
+---
+
+At this point, you have two options. Either add, commit and push the files
+directly back to GitLab or switch to Git LFS. We will tackle the LFS switch in
+the next section.
+
+### Enabling Git LFS in your repo
+
+Git LFS is enabled by default on all GitLab products (GitLab CE, GitLab EE,
+GitLab.com), therefore, you don't need to do anything server-side.
+
+1. First, make sure you have `git-lfs` installed locally:
+
+    ```bash
+    git lfs help
+    ```
+
+    If the terminal doesn't prompt you with a full response on `git-lfs` commands,
+    [install the Git LFS client][install-lfs] first.
+
+1. Inside the repo, run the following command to initiate LFS:
+
+    ```bash
+    git lfs install
+    ```
+
+1. Enable `git-lfs` for the group of files you want to track. You
+   can track specific files, all files containing the same extension, or an
+   entire directory:
+
+    ```bash
+    git lfs track images/01.png   # per file
+    git lfs track **/*.png        # per extension
+    git lfs track images/         # per directory
+    ```
+
+    Once you do that, run `git status` and you'll see `.gitattributes` added
+    to your repo. It collects all file patterns that you chose to track via
+    `git-lfs`.
+
+1. Add the files, commit and push them to GitLab:
+
+    ```bash
+    git add .
+    git commit -m "commit message"
+    git push
+    ```
+
+    If your remote is set up with HTTP, you will be asked to enter your login
+    credentials. If you have [2FA enabled][2fa], make sure to use a
+    [personal access token][token] instead of your password.
+
+## Removing the Git Annex branches
+
+After the migration finishes successfully, you can remove all `git-annex`
+related branches from your repository.
+
+On GitLab, navigate to your project's **Repository ➔ Branches** and delete all
+branches created by Git Annex: `git-annex`, and all under `synced/`.
+
+![repository branches](images/git-annex-branches.png)
+
+You can also do this on the commandline with:
+
+    ```bash
+    git branch -d synced/master
+    git branch -d synced/git-annex
+    git push origin :synced/master
+    git push origin :synced/git-annex
+    git push origin :git-annex
+    git remote prune origin
+    ```
+
+If there are still some Annex objects inside your repository (`.git/annex/`)
+or references inside `.git/config`, run `annex uninit` again:
+
+```bash
+git annex uninit
+```
