Also, shorten the overview a bit by removing some redundancy:
- Remove sentence 'A Bitcoin node verifies ... network.' because
its content is implied by the use cases (wallet, public infrastructure) mentioned in the
following sentence.
- 'second layer public infrastructure' -> 'public infrastructure',
because we're also serving the first layer.
This replaces minimal-configuration.nix.
importable-configuration.nix can be directly added to an existing
NixOS configuration. This makes it easy for users to get started quickly.
- Don't overwrite `nix-bitcoin-release.nix` on errors
- Show a message to indicate whether `nix-bitcoin-release.nix` was
updated
- Don't start a shell when called noninteractively
Also, update `usage.md` and reformat `shell.nix`.
Previously, when used to update `nix-bitcoin-release`, the error
wasn't displayed but instead written to `nix-bitcoin-release`.
Also, show curl error messages.
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.
These are insignificant, generic options; place them above readonly options.
We already do this in other services.
Also move user/group config to bottom in spark-wallet.
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.
The user's local node configuration directory usually contains a copy of
examples/shell.nix.
1. Move the shell implementation from shell.nix to nix-bitcoin/helper/makeShell.nix
Because the shell is no longer defined locally in the user's config
directory, we can now ship new shell features via nix-bitcoin updates.
2. Simplify examples/nix-bitcoin-release.nix
nix-bitcoin-release.nix, as generated via `fetch-release`, now
contains a simple fetchTarball statement which can be directly imported.
This allows us to get rid of the extra `nix-bitcoin-unpacked` derivation
which adds a dependency on the user's local nixpkgs.
To keep `fetch-release` as simple as possible for easy auditing, we just
fetch and verify a `nar-hash.txt` file that is now uploaded
via `push-release.sh`.
A migration guide for updating the user's local `shell.nix` is
automatically printed when the user starts a new shell after updating
nix-bitcoin.
This is achieved by throwing an error in `generate-secrets`, which is called
on shell startup.
This commit is required to deploy the new extensible `generate-secrets`
mechanism introduced in the next commit.
- Remove openssl.cnf which includes many unused settings.
- Generate the key and cert files with a single call to openssl.
- Option `-nodes` ("no DES") disables encryption of the key file.
- Option `-addext` is used to specify `subjectAltName` settings
that were previously defined by openssl.cnf.
The key type is unchanged.
Certificate changes:
- Certificate duration is now 10 years
- Organization (subj 'O') is now 'loop' instead of 'loopd' for
lightning-loop to simplify the code.
For reference, the org. name in auto-generated loop certs is
"loop autogenerated cert".
- The certificate now includes all default x509v3 extensions.
These were previously restricted to just `subjectAltName` by openssl.cnf.
We now use the openssl defaults for simplicity.
- btcpayserver: remove unneeded trailing semicolons
- krops/get-sha256:
`tail` is unneeded because `nix-prefetch-url` just outputs a single
line containing the hash.
There's no common `nix` command argument syntax for eval'ing a nix
expression that supports both older and newer (flake support) versions of nix.
So fall back to nix-instantiate.
joinmarket-ob-watcher now makes extensive use of bitcoind because of
JoinMarket's new fidelity bond functionality. Therefore it fails on
non-synced nodes, as those in the test suite. We now test that the
service fails with the correct error, rather than asserting that it is
running.
