# Shared files
|
|
|
|
Historically, GitLab has been storing shared files in many different
|
|
directories: `public/uploads`, `builds`, `tmp/repositories`, `tmp/rebase` (EE),
|
|
etc. Having so many shared directories makes it difficult to deploy GitLab on
|
|
shared storage (e.g. NFS). Working towards GitLab 9.0 we are consolidating
|
|
these different directories under the `shared` directory.
|
|
|
|
This means that if GitLab will start storing puppies in some future version
|
|
then we should put them in `shared/puppies`. Temporary puppy files should be
|
|
stored in `shared/tmp`.
|
|
|
|
In the GitLab application code you can get the full path to the `shared`
|
|
directory with `Gitlab.config.shared.path`.
|
|
|
|
## What is not a 'shared file'
|
|
|
|
Files that belong to only one process, or on only one server, should not go in
|
|
`shared`. Examples include PID files and sockets.
|
|
|
|
## Temporary files and shared storage
|
|
|
|
Sometimes you create a temporary file on disk with the intention of it becoming
|
|
'official'. For example you might be first streaming an upload from a user to
|
|
disk in a temporary file so you can perform some checks on it. When the checks
|
|
pass, you make the file official. In scenarios like this please follow these
|
|
rules:
|
|
|
|
- Store the temporary file under `shared/tmp`, i.e. on the same filesystem you
|
|
want the official file to be on.
|
|
- Use move/rename operations when operating on the file instead of copy
|
|
operations where possible, because renaming a file is much faster than
|
|
copying it.
