Do you think we are missing an alternative of stackage-install or a related project?
stackage-install provides a wrapper around the
cabal install command, which
will download packages more securely. Initially, this means downloading over an
HTTPS connection from FP Complete's Amazon S3 mirror of Hackage, though more
hardening is planned for the future (see future improvements below).
To install, simply run
cabal update && cabal install stackage-install. Usage
is intended to overlap well with
cabal install. Whenever you would have run
cabal install foo, you can now run
stackage-install foo (or
foo with stackage-cli installed), which
will perform the following steps:
cabal install --dry-run ...to get cabal's build plan
- Download the relevant packages from S3, and place them in the locations that
cabal install ...
In addition to using HTTPS for download,
stackage-install can use features of
repository for extra guarantees. In particular, if you have appropriate data in
your package index (see next paragraph),
stackage-install will automatically
verify both the hash of the package contents and the download size. If the
server attempts to send more data than expected, the download will be
If you have a modified
remote-repo in your ~/.cabal/config file, this tool
will not provide proper hardening. Most users do not modify their remote-repo,
so this shouldn't be an issue most of the time.
There are some combinations of
cabal install arguments which may not
translate well to this tool. One known issue is that passing
--dry-run is not
supported, but others may apply as well.
This tool necessarily has to call
cabal-install twice, once to calculate the
dependencies, and then to install them. It's theoretically possible that
cabal-install could come up with different build plans between the two calls,
in which case the second call may download some packages insecurely. I've
opened cabal issue #2566 about
disabling downloading in cabal.
The output from
cabal install --dry-run doesn't actually give us information
on which packages need to be downloaded, only the packages to be installed.
This will be different in the case of local packages. Unfortunately,
fetch won't work for us either, since it accepts different arguments see #2.
The compromise we have
now is to just continue working in the presence of errors during download,
though a more robust solution would be to check if one of the arguments refers
to a local package.
Why not fix cabal?
Hopefully cabal will get fixed soon, the discussion has already started. It's unfortunately unclear how long that discussion will take, and I received a specific request to write this tool. Since it's a small amount of code, I went ahead with this as an interim solution.
That said, some of the future enhancements discussed below are not planned for cabal, in which case this tool will continue to remain relevant for people looking for additional security beyond transport security.
- Check hashes of all packages downloaded against a collection of package hashes
- Verify signatures from authors against the signature archive
