This introduces rate limits for the `ChannelReader` to limit DDoS attacks and
attempts to upload repositories that are larger than a node is will to permit.
The limiter sets the total number of bytes it is will to accept in a single
exchange, defaulting to 500MB. This means that initial fetches will prevent
large repositories, but is plenty for new packfile data to be sent in subsequent
fetch exchanges.
The limit can be configured within the node's config file, under the limits.
Adds `set`, `add`, `remove`, `delete` to `rad config`.
Note that the changes will affect the configuration file, but not the
running instances. For changes to be reflected in the running instances
the node would need to be restarted.
This is a change to the `config.json` file which removes certain options
that are best not touched and changes some options to make them easier
to work with.
1. We change the default journaling mode to "wal" and remove the config
option.
2. We remove the option to set the peer connection "target", as it's not
a good idea to set this to a different value, as it affects the
network.
3. We combine seeding policy & scope, since there's no need to set the
scope when the policy is "block". In that case, we always want to
block "all" remotes. The new policy configuration has the following
schema:
{ seedingPolicy: { default: "block" | "allow", scope?: "all" | "followed" } }
The "scope" key is not used when "default" is set to "block".
4. We add an `extra` field to the node config for options that are not
recognized. We use this to warn the user.
*Breaking change* The `tor` configuration field is no longer
supported. Users must remove that field from their config.
Allows for a mixed mode, where regular addresses bypass the Tor proxy,
while onion addresses go through it.
When `onion.mode` is set to "forward", Tor connections are fowarded to
the global proxy, and if it isn't set, to the OS's DNS resolution.
For mixed mode, a global proxy simply isn't set, so that IP/DNS is not
proxied.
The rate-limitter gets hit on connect, due to historical gossip messages
being exchanged. This results in a high initial burst that needs to be
accounted for.
Relay now has three values: "always", "never" and "auto".
The first two operate like the previous `true`/`false`. The
new (default) value turns relaying on for nodes with public (external)
addresses and off for nodes without. This should reduce redundant traffic on
the network, that was causing the rate limiters to trigger.
With the increase in traffic on the network after launch, the old
defaults don't make sense anymore.
Longer term, we should look into throttling outgoing messages as well,
prioritizing original messages over relayed messages.
This makes the default policy `block` with scope `all`. The good thing
about this is that you don't have to manage individual nodes in the
beginning. You simply seed the repos you want, and everything is
followed within those repos. This matches user expectations, as `rad
seed` does what you expect it to do.
For open-policy seed nodes, it also means that simply changing `block`
to `allow` from the default config is all you need.
This leaves the non-default `followed` scope as a more "advanced"
setting, since it is much more cumbersome: it forces you to follow a
user before you can see their issues/patches, which is not something
most users expect coming from old-shcool forges.
When using `network: "test"`, we shouldn't default to any public seed
node. This change makes sure that the "preferredSeeds" configuration var
is only given a value when `network` is `main`.
Introduce pinned repositories to the `profile::Config`, i.e.
`config.json`.
This is used for pinning repositories in the httpd `/projects` handle.
To allow returning all repositories, an `all` query parameter is also
included.
This is non-backwards compatible change, since we introduce the `show`
query parameter which, if not supplied, will default to `pinned`.
