It turns out that the netencode spec requiring to ignore *later*
entries meant that every parser has to do an extra check for each
element, instead of just overriding the key in the hash map.
This leads to a situation where the simple implementation is the wrong
one, which would lead to very subtle problems in parsers (see also the
infamous “json duplicate record entry” problem which has been used for
various exploits in the past).
To be fair, exploits are still possible, but at least a `Map.fromList`
will be the right implementation (provided it folds from the left) now
instead of the wrong one.
Examples of the trivial implementation being now right:
Python:
> dict([("foo", 1), ("foo", 2)])
{'foo': 2}
Rust:
> println!("{:?}", HashMap::from([
("foo", 1),
("foo", 2)
]));
{"foo": 2}
Haskell:
> Data.Map.fromList [ ("foo", 1), ("foo", 2) ]
fromList [("foo",2)]

depot
This repository is the monorepo for the community around The Virus Lounge, containing our personal tools and infrastructure. Everything in here is built using Nix.
A large portion of the software here is very self-referential, meaning that it exists to sustain the operation of the repository. This is the case because we partially see this as an experiment in tooling for monorepos.
Highlights
Services
-
Source code is available primarily through Sourcegraph on cs.tvl.fyi, where it is searchable and even semantically indexed. A lower-tech view of the repository is also available via cgit on code.tvl.fyi.
The repository can be cloned using
gitfromhttps://cl.tvl.fyi/depot. -
All code in the depot, with the exception of code that is checked in to individual
//usersfolders, needs to be reviewed. We use Gerrit on cl.tvl.fyi for this. -
Issues are tracked via our own issue tracker on b.tvl.fyi. Its source code lives at
//web/panettone/. -
Smaller todo-list entries which do not warrant a separate issue are listed at todo.tvl.fyi.
-
We use Buildkite for CI. Recent builds are listed on tvl.fyi/builds and pipelines are configured dynamically via
//ops/pipelines. -
A search service that makes TVL services available via textual shortcuts is available: atward
All services that we host are deployed on NixOS machines that we manage. Their
configuration is tracked in //ops/{modules,machines}.
