hubuum-client 0.0.3

Modern typed Python client for Hubuum server v0.0.5

Hubuum client library (Python)

hubuum-client is a modern, fully typed Python client for the Hubuum asset-management API. It provides matching synchronous and asynchronous clients, Pydantic v2 models, typed resource IDs, immutable queries, cursor pagination, structured errors, and a contract-checked interface for all 196 operations in the server's OpenAPI surface.

Version 0.0.3 targets Hubuum server v0.0.5. Compatibility is tested against the tag-and-digest server image recorded in the compatibility matrix. Client version 0.0.2 remains the v0.0.4-compatible baseline.

Installation

python -m pip install hubuum-client

Python 3.11 or newer is required. The runtime dependencies are only HTTPX and Pydantic.

Quick start

from hubuum_client import ClassCreate, Client, Credentials, Query

with Client("https://hubuum.example.com") as client:
    client.login(Credentials("alice", "correct-horse-battery-staple"))

    classes = client.classes.list(
        Query().where("name", "server").limit(25).include_total()
    )

    created = client.classes.create(
        ClassCreate(
            name="server",
            collection_id=1,
            description="Server inventory",
        )
    )
    print(created.id, len(classes))

The asynchronous API has the same shape:

import asyncio

from hubuum_client import AsyncClient, Credentials, Query


async def main() -> None:
    async with AsyncClient("https://hubuum.example.com") as client:
        await client.login(Credentials("alice", "secret"))
        page = await client.classes.by_name("Servers").objects.page(
            Query().where("name", "web-01").include_total()
        )
        print(page.total_count, page.items)


asyncio.run(main())

Context-managed clients remain open for the entire block and reuse their HTTP connection pools. Applications that manage startup and shutdown explicitly can keep the same client for their full lifetime:

client = Client("https://hubuum.example.com")
try:
    client.login(Credentials("alice", "secret"))
    run_application(client)
finally:
    client.close()

The async equivalent uses await client.close(). Reuse a client instead of constructing one per request so eligible TCP/TLS connections can be reused; see Client setup for synchronous and asynchronous lifetime examples.

Credentials and bearer tokens have redacted representations. TLS certificate validation is enabled by default; disabling it is an explicit client option and should be limited to disposable development systems.

Hubuum v0.0.5 reports the authoritative expiry for newly issued tokens. After login or token minting, it is available as client.token.expires_at or created_token.expires_at. The unauthenticated public configuration reports the default used when no explicit expiry is requested:

config = client.config()
default_hours = config.authentication.default_token_lifetime_hours

Resource services

The typed surface currently covers the most common Hubuum workflows:

• collections, hierarchy traversal, and parent moves;
• classes and class-scoped objects, including exact-name addressing and nested data filtering and atomic JSON Patch;
• users, groups, memberships, and user anonymization;
• scoped token listing, minting, and revocation;
• class relations and object relations;
• typed grouped and multi-measure object aggregates;
• cursor pagination and task polling;
• health, readiness, and public server configuration.

Every v0.0.5 OpenAPI operation is registered by its stable operationId:

from hubuum_client import OpenAPIOptions

result = client.openapi.call(
    "getApiV1Search",
    options=OpenAPIOptions(params={"q": "server", "limit_per_kind": 10}),
)

The checked-in manifest covers all 196 methods, paths, path variables, body media types, public/authenticated policies, JSON responses, rendered text exports, and the search event stream. request() remains available for server extensions outside the pinned specification. Both interfaces are constrained to the configured origin.

Querying and pagination

Queries are immutable and reusable:

from hubuum_client import FilterOperator, Query

base = Query().where("name", "server", FilterOperator.ICONTAINS)
first_page = client.classes.page(base.limit(25).include_total())
all_matches = client.classes.all(base, max_items=5_000)

active_web_servers = client.classes.by_name("Servers").objects.all(
    Query()
    .data("status")
    .equals("active")
    .data("tags")
    .contains_all("web", "api")
)

Page exposes items, next_cursor, total_count, and the effective page_limit. Automatic pagination detects repeated cursors and enforces page and item limits. The fluent data() selector supports nested paths, typed comparisons, arrays, nulls, object keys, and IP/network operators; see Queries and pagination.

Group membership uses the same typed, cursor-aware interface:

member_page = client.groups.members_page(group_id, Query().limit(25).include_total())
all_members = client.groups.all_members(group_id, max_items=5_000)
