Full Description


This is the hackage-server code. This is what powers, and many other private hackage instances.

Installing ICU

ICU stands for "International Components for Unicode". The icu4c is a set
of libraries that provide Unicode and Globalization support.
The text-icu Haskell package
uses the icu4c library to build.

You'll need to do the following to get hackage-server's dependency text-icu to build:

Mac OS X

brew install icu4c
brew link icu4c --force


sudo apt-get update
sudo apt-get install unzip libicu-dev

Setting up security infrastructure

Out of the box the server comes with some example keys and TUF metadata. The
example keys are in example-keys/; these keys were used to create


While these files will enable you to start the server without doing anything
else, you should replace all these files before deploying your server. In the
remainder of this section we will explain how to do that.

The first step is to create your own keys using the

hackage-repo-tool create-keys --keys /path/to/keys

Then copy over the timestamp and snapshot keys to the TUF directory:

cp /path/to/keys/timestamp/<id>.private datafiles/TUF/timestamp.private
cp /path/to/keys/snapshot/<id>.private  datafiles/TUF/snapshot.private

Create root information:

hackage-repo-tool create-root --keys /path/to/keys -o datafiles/TUF/root.json

And finally create a list of mirrors (this is necessary even if you don't have
any mirrors):

hackage-repo-tool create-mirrors --keys /path/to/keys -o datafiles/TUF/mirrors.json

The create-mirrors command takes a list of mirrors as additional arguments if
you do want to list mirrors.

In order for secure clients to bootstrap the root security metadata from your
server, you will need to provide them with the public key IDs of your root keys;
you can find these as the file names of the files created in
/path/to/keys/root (as well as in the generated root.json under the
signed.roles.root.keyids). An example cabal client configuration might look
something like

remote-repo my-private-hackage
  secure: True
  root-keys: 865cc6ce84231ccc990885b1addc92646b7377dd8bb920bdfe3be4d20c707796
  key-threshold: 2


cabal install -j --enable-tests

hackage-server init
hackage-server run

If you want to run the server directly from the build tree, run

dist/build/hackage-server/hackage-server run --static-dir=datafiles/

By default the server runs on port 8080 with the following settings:

URL:      http://localhost:8080/
username: admin
password: admin

To specify something different, see hackage-server init --help for details.

The server can be stopped by using Control-C.

This will save the current state and shutdown cleanly. Running again
will resume with the same state.


To reset everything, kill the server and delete the server state:

rm -rf state/

Note that the datafiles/ and state/ directories differ:
datafiles is for static html, templates and other files.
The state directory holds the database (using acid-state
and a separate blob store).

Creating users & uploading packages

Currently there is no restriction on registering, but only an admin
user can grant privileges to registered users e.g. by adding them to
other groups. In particular there are groups:

  • admins http://localhost:8080/users/admins/ -- administrators can
    do things with user accounts like disabling, deleting, changing
    other groups etc.
  • trustees http://localhost:8080/packages/trustees/ -- trustees can
    do janitorial work on all packages
  • mirrors http://localhost:8080/packages/mirrorers/ -- for special
    mirroring clients that are trusted to upload packages
  • per-package maintainer groups
    http://localhost:8080/package/foo/maintainers -- users allowed to
    upload packages
  • uploaders http://localhost:8080/packages/uploaders/ -- for
    uploading new packages


There is a client program included in the hackage-server package called
hackage-mirror. It's intended to run against two servers, syncing all the
packages from one to the other, e.g. getting all the packages from the old
hackage and uploading them to a local instance of a hackage-server.

To try it out:

  1. On the target server, add a user to the mirrorers group via
  2. Create a config file that contains the source and target
    servers. Assuming you are cloning the packages on locally, create the file servers.cfg:
    source "hackage"
    type: hackage2

target "mirror"
uri: http://admin:admin@localhost:8080/
type: local

post-mirror-hook: "shell command to execute"

Recognized types are hackage2, secure and local. The target server name was displayed when you ran
   hackage-server run.
  1. Run the client, pointing to the config file:
hackage-mirror servers.cfg

This will do a one-time sync, and will bail out at the first sign of
trouble. You can also do more robust and continuous mirroring. Use the
flag --continuous. It will sync every 30 minutes (configurable with
--interval). In this mode it carries on even when some packages
cannot be mirrored for some reason and remembers them so it doesn't
try them again and again. You can force it to try again by deleting
the state files it mentions.
