envs-xmpp

Shared technical infrastructure for the envs.net XMPP bots envsbot and muc_banbot.

One distribution intentionally ships two stable Python packages:

• envs_xmpp_core: bot-neutral runtime, XMPP, config, storage and release primitives.
• envs_xmpp_ops: deployment and operations primitives.

Keeping both in one distribution gives runtime and deployment infrastructure one version, one repository and one release pipeline while preserving the existing import APIs used by both bots.

The package contains no bot commands, permissions, database schemas, moderation logic, plugin systems or bot-specific lifecycle policy.

Compatibility

• Python 3.12 and 3.13
• GPL-3.0-only
• no mandatory third-party runtime dependencies

The bots themselves remain responsible for dependencies such as Slixmpp.

Shared storage primitives include SQLite integrity checking and safe ZIP member validation/streaming. Pending room invites use a shared typed model, deduplication, store state machine and SQL repository while each bot keeps only a thin database-API adapter and bot-specific notification/join policy. Declarative config-schema primitives provide shared default/type/range/lifecycle metadata; each bot keeps its domain-specific validation, reload behavior and operator-facing wording local. Pagination provides a neutral page-slice model while bot frontends retain their existing command-specific return formats.

Installation

Install the stable package from PyPI:

python -m pip install envs-xmpp
python -c "import envs_xmpp_core; print(envs_xmpp_core.__version__)"

For development, install a checkout in editable mode:

python -m pip install -e /path/to/envs-xmpp

Existing imports remain valid:

from envs_xmpp_core.runtime.tasks import TaskSupervisor
from envs_xmpp_ops.profile import DeploymentProfile

Stable 1.x API

Version 1.0 formalized package-level convenience imports for the shared infrastructure introduced during the bot consolidation. The public surfaces are envs_xmpp_core.xmpp, envs_xmpp_core.storage, envs_xmpp_core.runtime, envs_xmpp_core.security, and envs_xmpp_ops. Direct module imports remain supported, so existing consumers do not have to migrate immediately.

The stable shared layer now covers avatar/profile publication, confirmed MUC joins, normalized occupant identity, message-target/reply routing, durable outbox storage, operational alert state, redacted diagnostics and deployment layout discovery. Version 1.1 adds the shared operator-presentation models and renderers for task, status and room inventories. Version 1.2 adds shared JID text normalization, including deliberately narrow cleanup of U+200B/U+FEFF copy/paste artifacts before best-effort bare-JID comparison. Version 1.3 adds shared reconnect retry/backoff orchestration that waits for full application readiness, avoids duplicate transport attempts during session-start races, and resets partial sessions after bounded startup timeouts. The bots still own disconnect cleanup, room/state reconciliation, readiness criteria, alerts and other application policy. The 1.x line also shares XMPP session-generation telemetry and bounded MUC affiliation IQ mechanics while keeping strict JID validation and bot policy in the applications. Bot-specific command behavior, moderation, OMEMO, plugin systems and notification wording intentionally remain outside the core.

envs_xmpp_ops is designed for thin bot-specific deployment frontends. The frontends subclass the shared DeploymentTarget for common checkout/venv/config/ service coordinates and keep bot policy such as config migration, database backup/restore and service hardening local. Shared Git release selection, systemd inspection, operator confirmation, account/path checks, virtualenv creation and consumer release-state auditing live here.

Fresh installs do not assume that this package is already present. Each bot ships a tiny stdlib-only bootstrap shim. When the exact required envs-xmpp version is unavailable, that shim creates a versioned cached deployment virtualenv below $XDG_CACHE_HOME/envs-xmpp/deploy/ (or ~/.cache/envs-xmpp/deploy/), installs the pinned version from PyPI, and re-executes the deployment frontend. ENVS_XMPP_DEPLOY_SOURCE can point at a local checkout or wheel for development and pre-release testing.

Documentation

• Developer guide
• Architecture and ownership boundaries
• Stable API reference
• Consolidation policy

The documentation intentionally distinguishes stable public imports from internal implementation details. Bot-specific policy should stay in the applications unless it has demonstrably identical semantics in more than one consumer.

CI and PyPI releases

GitHub Actions tests Python 3.12 and 3.13. A vX.Y.Z tag is accepted only when it exactly matches project.version in pyproject.toml. Release distributions are published through PyPI Trusted Publishing/OIDC, without a long-lived PyPI token.

PyPI publishing is configured through the pypi GitHub environment and the Trusted Publisher for envs-net/envs-xmpp using .github/workflows/release.yml.

Shared developer quality runners

envs_xmpp_ops.quality and envs_xmpp_ops.testing provide the common local quality/test frontends used by envsbot and muc_banbot. Project-specific source targets, generated-file checks, integration markers and coverage floors remain declarative in each repository's pyproject.toml; the runner behavior and gate ordering stay shared.

The quality runner enforces a common baseline: compilation, project validation, warning-strict tests, Ruff repository/F401/I-UP-B gates, mypy, Git whitespace validation and dependency audit. Consumer project validation can include python -m envs_xmpp_ops.release_audit, which verifies that package metadata, requirements, constraints and the deploy bootstrap agree on one shared-core version before a release is cut.

Runtime and utility primitives

The shared core also provides heartbeat-aware worker waits, lifecycle phase orchestration, passive HealthCheck/HealthSnapshot diagnostics with failure-isolated collection, normalized task/watchdog/lifecycle/room-inventory facts, ordered health-message flattening, asynchronous release comparison results, and neutral human-readable duration/byte formatting. Applications keep notification policy, active recovery behavior, severity decisions, concrete domain checks and labels locally.
