Storage buckets, indexer names, the bleve analyzer, the lock prefix, SSH host keys, the markdown front-matter key, the container data paths, the RPM repo id and the API security scheme all read as this product now, and app.example.ini matches the code again. The upstream maintainer list and the changelog generator config went with the release history they belonged to, and the citation comments state the fact rather than link the issue. Three inert rules turn out to have been inert because they named a module path this tree does not use: gci grouped no first-party imports under prefix(), and depguard let models/migrations import models and modules/structs. They now name github.com/hanzoai/git. The config example also documented .gitea/workflows while the code has read .hanzo/workflows for some time. The authorized_keys marker follows the delegate-hook precedent: the new name is written and the old one is still recognised, because a marker we do not know is copied through as a hand-added key and leaves a revoked key authorized. The stored user_setting key keeps its value; only a migration may change that. Co-authored-by: Hanzo Dev <[email protected]>
Hanzo Forge Package Registry
This document gives a brief overview how the package registry is organized in code.
Structure
The package registry code is divided into multiple modules to split the functionality and make code reuse possible.
| Module | Description |
|---|---|
models/packages |
Common methods and models used by all registry types |
models/packages/<type> |
Methods used by specific registry type. There should be no need to use type specific models. |
modules/packages |
Common methods and types used by multiple registry types |
modules/packages/<type> |
Registry type specific methods and types (e.g. metadata extraction of package files) |
routers/api/packages |
Route definitions for all registry types |
routers/api/packages/<type> |
Route implementation for a specific registry type |
services/packages |
Helper methods used by registry types to handle common tasks like package creation and deletion in routers |
services/packages/<type> |
Registry type specific methods used by routers and services |
Models
Every package registry implementation uses the same underlying models:
| Model | Description |
|---|---|
Package |
The root of a package providing values fixed for every version (e.g. the package name) |
PackageVersion |
A version of a package containing metadata (e.g. the package description) |
PackageFile |
A file of a package describing its content (e.g. file name) |
PackageBlob |
The content of a file (may be shared by multiple files) |
PackageProperty |
Additional properties attached to Package, PackageVersion or PackageFile (e.g. used if metadata is needed for routing) |
The following diagram shows the relationship between the models:
Package <1---*> PackageVersion <1---*> PackageFile <*---1> PackageBlob
Adding a new package registry type
Before adding a new package registry type have a look at the existing implementation to get an impression of how it could work.
Most registry types offer endpoints to retrieve the metadata, upload and download package files.
The upload endpoint is often the heavy part because it must validate the uploaded blob, extract metadata and create the models.
The methods to validate and extract the metadata should be added in the modules/packages/<type> package.
If the upload is valid the methods in services/packages allow to store the upload and create the corresponding models.
It depends if the registry type allows multiple files per package version which method should be called:
CreatePackageAndAddFile: error if package version already existsCreatePackageOrAddFileToExisting: error if file already existsAddFileToExistingPackage: error if package version does not exist or file already exists
services/packages also contains helper methods to download a file or to remove a package version.
There are no helper methods for metadata endpoints because they are very type specific.
