hfortix-core 0.5.164

Core foundation for HFortix - Fully-typed Fortinet SDK with async support and type safety

HFortix-Core

HFortix-Core is the shared foundation for the HFortix ecosystem: HTTP client infrastructure (REST, JSON-RPC, and FortiCloud OAuth2), a complete exception hierarchy, retry/circuit-breaker/rate-limit resilience, audit and structured logging, caching, and formatting utilities.

🚀 Quick Start

pip install hfortix-core

Note: This is a foundational library. Most users should install hfortix-fortios (FortiGate), hfortix-fortimanager, hfortix-forticare, hfortix-fortiztp, or the hfortix meta-package instead.

Direct usage — FortiOS REST client:

from hfortix_core.http import HTTPClient
from hfortix_core import APIError, RetryableError

client = HTTPClient(
    url="https://192.168.1.99",
    token="your-api-token",
    verify=True,
    max_retries=3,
)

try:
    # The client prepends /api/v2/<api_type>/ — pass only the endpoint path
    response = client.get("cmdb", "firewall/policy")
except RetryableError as e:
    print(f"Transient failure after retries: {e.message}")
except APIError as e:
    print(f"API error: {e.message} (HTTP {e.http_status})")
finally:
    client.close()

FortiManager / FortiAnalyzer JSON-RPC client:

from hfortix_core import HTTPClientJSONRPC

fmg = HTTPClientJSONRPC(
    url="https://fmg.example.com",
    username="admin",
    password="password",
)
fmg.login()
result = fmg.execute("get", [{"url": "/dvmdb/adom/root/device"}])
fmg.logout()

FortiCloud (FortiCare / FortiZTP) OAuth2 session:

from hfortix_core.session import CloudSession

with CloudSession(api_id="your-api-id", password="your-password") as session:
    token = session.get_token("assetmanagement")  # per-service OAuth2 token

📦 What's Included

HTTP Client Framework (hfortix_core.http)

All clients subclass BaseHTTPClient and share retry logic, opt-in circuit breaker and rate limiting, connection pooling (HTTP/2 via httpx), audit/debug hooks, and request statistics:

• HTTPClient / AsyncHTTPClient — FortiOS REST (used by hfortix-fortios)
• HTTPClientJSONRPC — FortiManager/FortiAnalyzer JSON-RPC (HTTPClientFMG remains as a backwards-compatibility alias)
• CloudHTTPClient — FortiCloud REST with OAuth2 bearer tokens (used by hfortix-forticare and hfortix-fortiztp)
• FortiCloudAuth / get_oauth_token — FortiCloud OAuth2 token acquisition
• IHTTPClient — protocol interface for injecting custom clients

Resilience (opt-in)

Both features are disabled by default and enabled via constructor keywords on any client:

client = HTTPClient(
    url="https://192.168.1.99",
    token="...",
    rate_limit=True,                 # client-side throttling
    rate_limit_max_requests=100,
    rate_limit_window_seconds=60.0,
    rate_limit_strategy="queue",     # "queue" | "drop" | "raise"
    circuit_breaker=True,            # fail fast when the device is down
    circuit_breaker_threshold=5,
    circuit_breaker_timeout=60.0,
)

RateLimitStats additionally provides enforcement-free tracking of call and error rates across 1-minute/5-minute/1-hour windows.

Exception Hierarchy (hfortix_core.exceptions)

One hierarchy for every HFortix package, rooted at FortinetError, with an explicit retry split under APIError:

• RetryableError — RateLimitError (429), ServerError (500), ServiceUnavailableError (503), TimeoutError, CircuitBreakerOpenError
• NonRetryableError — BadRequestError (400), ResourceNotFoundError (404), MethodNotAllowedError (405), DuplicateEntryError, EntryInUseError, InvalidValueError, PermissionDeniedError
• AuthenticationError / AuthorizationError inherit directly from FortinetError (not APIError) — catch them explicitly
• Every exception exposes .message (original message) plus rich context (http_status, error_code, endpoint, hint, ...) on APIError
• Helpers: raise_for_status() (maps ~300 FortiOS error codes), is_retryable_error(), get_retry_delay(), get_error_description()

Session Management (hfortix_core.session)

• CloudSession — multi-service OAuth2 token management with per-client_id token sharing, optional background refresh, pluggable token storage backends, and lifecycle hooks

Utilities

• TTLCache — simple in-memory TTL cache for readonly reference data
• fmt — output formatting helpers (to_table, to_json, to_yaml, to_csv, to_markdown_table, to_xml, and more)
• Audit logging (hfortix_core.audit) — Syslog/File/Stream/Composite handlers with JSON/CEF/Syslog formatters for compliance logging
• Structured logging (hfortix_core.logging) and debug tooling (hfortix_core.debug)
• TypedDict definitions (hfortix_core.types) — PEP 561 typed distribution
