This makes scripts fail early on request errors.
Previously, curl exited with status 0 when enountering HTTP error status
codes.
`-fsS` equals `--fail --silent --show-error`.
This makes our list definitions mergeable with custom list values
set by users.
Previously, a module error ("value is a string while a list
was expected") was thrown instead.
This commit was partly auto-generated with this script:
#!/usr/bin/env ruby
Dir["**/*.nix"].each do |file|
src = File.read(file)
fixed = src.gsub(/ReadWritePaths *= *(.*?);/) do
"ReadWritePaths = [ #{$1} ];"
end
File.write(file, fixed) if fixed != src
end
This enables generating module option documentation.
This commit was genereated by running the following script inside the
repo root dir:
def add_default_text(file)
src = File.read(file)
src2 = src.gsub(/( = mkOption\s+\{[^{]*?)(\n\s+default = )(.*?);$(.*?\})/m) do |str|
pre, defaultVar, default, post = Regexp.last_match.captures
replacement =
if !post.include?('defaultText =')
if default =~ /\bpkgs\b/
defaultText = default.lines.length == 1 ? default : "(See source)"
"#{pre}#{defaultVar}#{default};#{defaultVar.sub('default', 'defaultText')}#{defaultText.inspect};#{post}"
end
end
replacement or str
end
File.write(file, src2) if src2 != src
end
Dir["modules/**/*.nix"].each do |f|
next if File.basename(f) == "nix-bitcoin.nix"
add_default_text f
end
Split `enforceTor` into `tor.proxy` and `tor.enforce`.
By enabling `tor.proxy` without `tor.enforce`, a service can accept
incoming clearnet connections.
E.g., this allows setting up a Tor-proxied bitcoind node that accepts
RPC connections from LAN.
- bitcoind: Remove obsolete defaultText
- clightning: Fix description
Option `address` can't be used to specify a socket path because it's
used explicitly as an IP address in many places.
- lnd: Break up overlong line
This is required by commit `services: support 0.0.0.0/:: in `address` options`
- nix-bitcoin.nix: Formatting
- secrets: Improve descriptions
Benefits of adding top-level variables for used services:
- Makes it obvious which other services are referenced by a service
- Less code
We already do this in many other places.
This greatly improves readability and makes it easier to discover options.
This commit was genereated by running the following script inside the
repo root dir:
#!/usr/bin/env ruby
def transform(src)
return false if src.include?('inherit options;')
success = false
options = nil
src.sub!(/^ options.*?^ }.*?;/m) do |match|
options = match
" inherit options;"
end
return false if !options
src.sub!(/^with lib;\s*let\n+/m) do |match|
success = true
<<~EOF
with lib;
let
#{options}
EOF
end
success
end
Dir['modules/**/*.nix'].each do |f|
src = File.read(f)
if transform(src)
puts "Changed file #{f}"
File.write(f, src)
end
end
`generate-secrets` is no longer a monolithic script. Instead, it's
composed of the values of option `nix-bitcoin.generateSecretsCmds`.
This has the following advantages:
- generate-secrets is now extensible by users
- Only secrets of enabled services are generated
- RPC IPs in the `lnd` and `loop` certs are no longer hardcoded.
Secrets are no longer automatically generated when entering nix-shell.
Instead, they are generated before deployment (via `krops-deploy`)
because secrets generation is now dependant on the node configuration.
nix-bitcoin.nix is now no longer dependent on clightning.nix and lnd.nix.
Due to condition '!(config.services ? clightning)' lnd.nix still
doesn't depend on clightning.nix.
Also fix the assertion message by renaming clightning.bindPort to clightning.port.
Due to a possible NixOS bug, this commit has no effect on NixOS 20.09
where `RestrictAddressFamilies` is a no-op.
It's only relevant for NixOS unstable with cgroups v2.
bitcoind+zmq: instead of allowing all address families, only add the required
AF_NETLINK family.
lnd: lnd only runs a zmq client, not a server, therefore it requires
no additional address families.
lightning-pool, clightning-plugin-zmq: add AF_NETLINK.
Keeping the secrets dir read-only is more simple and robust.
- lnd seed mnemonic creation and joinmarket wallet creation can be
run as the regular service user instead of root.
- It is easier to switch to a third-party secrets deployment
method in the future.
Don't create a seed mnemonic for lnd when a wallet exists.
This avoids creating unused mnemonics and helps simplifying
the migration command in `versioning.nix`.
Use the following order of definitions for all services:
- assertions
- configuration of other services
- environment.systemPackages
- tmpfiles
- own service
- users
- secrets
Systemd's `Description` option is a misnomer (as confessed by `man systemd.unit`):
Its value is used by user-facing tools in place of the unit file name, so this option
could have been more aptly named `label` or `name`.
`Description` should only be set if the unit file name is not sufficient for naming a unit.
This is not the case for our services, except for `systemd.services.nb-netns-bridge`
whose description has been kept.
As an example how this affects users, weird journal lines like
```
nb-test systemd[1]: Starting Run clightningd...
```
are now replaced by
```
nb-test systemd[1]: Starting clightning.service...
```
