This is the hackage-server
code. This is what powers http://hackage.haskell.org, and many other private hackage instances. The master
branch is suitable for general usage. Specific policy and documentation for the central hackage instance exists in the central-server
branch.
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:
brew install icu4c
brew link icu4c --force
sudo apt-get update
sudo apt-get install unzip libicu-dev
sudo dnf install unzip libicu-devel
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
datafiles/TUF/root.json
datafiles/TUF/mirrors.json
datafiles/TUF/timestamp.private
datafiles/TUF/snapshot.private
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:
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
repository my-private-hackage
url: http://example.com:8080/
secure: True
root-keys: 865cc6ce84231ccc990885b1addc92646b7377dd8bb920bdfe3be4d20c707796

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).
- Admin front-end: http://localhost:8080/admin
- List of users: http://localhost:8080/users/
- Register new users: http://localhost:8080/users/register
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:
- On the target server, add a user to the mirrorers group via http://localhost:8080/packages/mirrorers/
- Create a config file that contains the source and target servers. Assuming you are cloning the packages on http://hackage.haskell.org locally, create the file servers.cfg:
source "hackage"
uri: http://hackage.haskell.org
type: secure
target "mirror"
uri: http://admin:admin@localhost:8080
type: hackage2
post-mirror-hook: "shell command to execute"
Recognized types are hackage2, secure and local. The target server name was displayed when you ran.
Note, the target must not have a trailing slash, or confusion will tend to occur. Additionally, if you have ipv6 setup on the machine, you may need to replace localhost
with 127.0.0.1
.
Also note that you should mirror from hackage2 or secure typically and mirror to hackage2. Only mirroring from secure will include dependency revision information.
hackage-server run.
- 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.
