localshop: A Python repository from olarcheveque

localshop

A pypi server which automatically proxies and mirrors pypi packages based upon packages requested. It also supports the uploading of local (private) packages.

Supported Python versions: 2.6 & 2.7.

Getting started

Download and install localshop via the following command:

pip install localshop

This should best be done in a new virtualenv. Now initialize your localshop environment by issuing the following command:

localshop init

If you are upgrading from an earlier version simply run:

localshop upgrade

And then start it via:

localshop run_gunicorn
localshop celery worker -B -E

Celeryd is required to do the mirroring of the pypi packages once they are needed.

If you like to start listening on a different network interface and HTTP port, you can use the parameter "0.0.0.0:80" after "run_gunicorn". This example will make your system listen to all network interfaces on port 80. This affects all URL examples below, because they are using 8000 (the default HTTP port).

You can also start it via honcho using the Procfile:

pip install honcho
honcho start

You can now visit http://localhost:8000/ and view all the packages in your localshop!

The next step is to give access to various hosts to use the shop. This is done via the webinterface (menu -> permissions -> cidr). Each ip address listed there will be able to download and upload packages. If you are unsure about ips configuration, but still want to use authentication, specify "0.0.0.0/0" as the unique cidr configuration. It will enable for any ip address.

How it works

Packages which are requested and are unknown are looked up on pypi via the xmlrpc interface. At the moment the client downloads one of the files which is not yet mirror'ed a 302 redirect is issued to the correct file (on pypi). At that point the worker starts downloading the package and stores it in ~/.localshop/files so that the next time the package is request it is available within your own shop!

Uploading local/private packages

To upload your own packages to your shop you need to modify/create a .pypirc file. See the following example:

[distutils]
index-servers =
    local

[local]
username: myusername
password: mysecret
repository: http://localhost:8000/simple/

To upload a custom package issue the following command in your package:

python setup.py upload -r local

It should now be available via the webinterace

Using the shop for package installation

To install packages with pip from your localshop add -i flag, e.g.:

pip install -i http://localhost:8000/simple/ localshop

or edit/create a ~/.pip/pip.conf file following this template:

[global]
index-url = http://<access_key>:<secret_key>@localhost:8000/simple

Then just use pip install as you are used to do. You can replace access_key and secret_key by a valid username and password.

Credentials for authentication

If you don't want to use your Django username/password to authenticate uploads and downloads you can easily create one of the random credentials localshop can create for you.

Go to the Credentials section and click on create. Use the access key as the username and the secret key as the password when uloading packages. A .pypirc could look like this:

[distutils]
index-servers =
    local

[local]
username: 4baf221849c84a20b77a6f2d539c3e8a
password: 200984e70f0c463b994388c4da26ec3f
repository: http://localhost:8000/simple/

pip allows you do use those values in the index URL during download, e.g.:

pip install -i http://<access_key>:<secret_key>@localhost:8000/simple/ localshop

So for example:

pip install -i http://4baf221849c84a20b77a6f2d539c3e8a:200984e70f0c463b994388c4da26ec3f@localhost:8000/simple/ localshop

Warning

Please be aware that those credentials are transmitted unencrypted over http unless you setup your localshop instance to run on a server that serves pages via https.

In case you ever think a credential has been compromised you can disable it or delete it on the credential page.

Adding users

You can add users using the Django admin backend at /admin. In order for the user to be able to generate credentials for his account, he needs the following four user permissions:

permissions.add_credential
permissions.change_credential
permissions.delete_credential
permissions.view_credential

Settings

There are a few settings to set in ~/.localshop/localshop.conf.py that change the behaviour of the localshop.

`LOCALSHOP_DELETE_FILES`

default:	`False`

If set to True files will be cleaned up after deleting a package or release from the localshop.

`LOCALSHOP_DISTRIBUTION_STORAGE`

default:	`'storages.backends.overwrite.OverwriteStorage'`

The dotted import path of a Django storage class to be used when uploading a release file or retrieving it from PyPI.

`LOCALSHOP_HTTP_PROXY`

default:	`None`

Proxy configuration used for Internet access. Expects a dictionnary configured as mentionned by http://docs.python-requests.org/en/latest/user/advanced/#proxies

`LOCALSHOP_ISOLATED`

default:	`False`

If set to True Localshop never will try to redirect the client to PyPI. This is useful for environments where the client has no Internet connection.

Note

If you set LOCALSHOP_ISOLATED to True, client request can be delayed for a long time because the package must be downloaded from Internet before it is served. You may want to set pip environment variable PIP_DEFAULT_TIMEOUT to a big value. Ex: 300
