# SelfPrivacy GraphQL API which allows app to control your server
|
|
|
|
|
|
|
|
## Build
|
|
|
|
```console
|
|
$ nix build
|
|
```
|
|
|
|
In case of successful build, you should get the `./result` symlink to a folder (in `/nix/store`) with build contents.
|
|
|
|
## Develop
|
|
|
|
```console
|
|
$ nix develop
|
|
[SP devshell:/dir/selfprivacy-rest-api]$ python
|
|
Python 3.10.13 (main, Aug 24 2023, 12:59:26) [GCC 12.3.0] on linux
|
|
Type "help", "copyright", "credits" or "license" for more information.

```
|
|
|
|
If you don't have experimental flakes enabled, you can use the following command:
|
|
|
|
```console
|
|
$ nix --extra-experimental-features nix-command --extra-experimental-features flakes develop
|
|
```
|
|
|
|
## Testing
|
|
|
|
Run the test suite by running coverage with pytest inside an ephemeral NixOS VM with redis service enabled:
|
|
```console
|
|
$ nix flake check -L
|
|
```
|
|
|
|
Run the same test suite, but additionally create `./result/coverage.xml` in the current directory:
|
|
```console
|
|
$ nix build .#checks.x86_64-linux.default -L
|
|
```
|
|
|
|
Alternatively, just print the path to `/nix/store/...coverage.xml` without creating any files in the current directory:
|
|
```console
|
|
$ nix build .#checks.x86_64-linux.default -L --print-out-paths --no-link
|
|
```
|
|
|
|
Run the same test suite with arbitrary pytest options:
|
|
```console
|
|
$ pytest-vm.sh # specify pytest options here, e.g. `--last-failed`
|
|
```
|
|
When running using the script, pytest cache is preserved between runs in `.pytest_cache` folder.
|
|
NixOS VM state temporary resides in `${TMPDIR:=/tmp}/nixos-vm-tmp-dir/vm-state-machine` during the test.
|
|
Git workdir directory is shared read-write with VM via `.nixos-vm-tmp-dir/shared-xchg` symlink. VM accesses workdir contents via `/tmp/shared` mount point and `/root/source` symlink.
|
|
|
|
Launch VM and execute commands manually either in Linux console (user `root`) or using python NixOS tests driver API (refer to [NixOS documentation](https://nixos.org/manual/nixos/stable/#ssec-machine-objects)):
|
|
```console
|
|
$ nix run .#checks.x86_64-linux.default.driverInteractive
|
|
```
|
|
|
|
You can add `--keep-vm-state` in order to keep VM state between runs:
|
|
```console
|
|
$ TMPDIR=".nixos-vm-tmp-dir" nix run .#checks.x86_64-linux.default.driverInteractive --keep-vm-state
|
|
```
|
|
|
|
Option `-L`/`--print-build-logs` is optional for all nix commands. It tells nix to print each log line one after another instead of overwriting a single one.
|
|
|
|
## Dependencies and Dependant Modules
|
|
|
|
This flake depends on a single Nix flake input - nixpkgs repository. nixpkgs repository is used for all software packages used to build, run API service, tests, etc.
|
|
|
|
In order to synchronize nixpkgs input with the same from selfprivacy-nixos-config repository, use this command:
|
|
|
|
```console
|
|
$ nix flake lock --override-input nixpkgs nixpkgs --inputs-from git+https://git.selfprivacy.org/SelfPrivacy/selfprivacy-nixos-config.git?ref=BRANCH
|
|
```
|
|
|
|
Replace BRANCH with the branch name of selfprivacy-nixos-config repository you want to sync with. During development nixpkgs input update might be required in both selfprivacy-rest-api and selfprivacy-nixos-config repositories simultaneously. So, a new feature branch might be temporarily used until selfprivacy-nixos-config gets the feature branch merged.
|
|
|
|
Show current flake inputs (e.g. nixpkgs):
|
|
```console
|
|
$ nix flake metadata
|
|
```
|
|
|
|
Show selfprivacy-nixos-config Nix flake inputs (including nixpkgs):
|
|
```console
|
|
$ nix flake metadata git+https://git.selfprivacy.org/SelfPrivacy/selfprivacy-nixos-config.git?ref=BRANCH
|
|
```
|
|
|
|
Nix code for NixOS service module for API is located in NixOS configuration repository.
|
|
|
|
## Troubleshooting
|
|
|
|
Sometimes commands inside `nix develop` refuse to work properly if the calling shell lacks `LANG` environment variable. Try to set it before entering `nix develop`.
