Computes can now be flagged auto_connect in the database. The controller
connects to flagged computes in the background at startup (reusing the
one-second delayed fire-and-forget mechanism), and enabling the flag via
PUT /computes/{id} triggers a background connection without the request
ever waiting for it. Disabling the flag does not drop an existing
connection.
Add POST /computes/{id}/disconnect to tear a compute down manually: the
notification stream and HTTP session are closed and every reconnection
path (retry backoff, notification stream reconnect, lazy connection in
http_query) is blocked until connect() is called again or the controller
restarts with auto_connect enabled. Disconnecting a compute used by an
opened project is rejected with 409 unless force=true; forcing only
drops the controller-side control channel, nodes keep running unmanaged.
The local compute cannot be disconnected.
Also make test_compute_list create its own compute (it relied on rows
from earlier tests and failed under reordering), and stop scheduling the
delayed add_compute connection during tests: the timer leaked real
connection attempts into other tests' event loops.
Preserve image reconciliation, locking, and regression coverage while integrating upstream release, dependency, typing, and formatting updates. Align feature code with the new Ruff checks.
install_appliances_from_image relied on the name+version pair check in
TemplatesService, so the same appliance reached through a second image
(the CSR1000v case) created a second template sharing the name. The auto
path now skips when any template with the same name exists, whatever the
version, and returns a manifest of created and skipped candidates;
POST /images/install replies 200 with that manifest instead of an empty
204, and the image_install MCP tool surfaces it.
GET returns all settings sections except the deprecated
VirtualBox/VMware ones (Server.Audit privilege); secrets are
masked and Controller.jwt_secret_key is excluded entirely.
PUT applies a partial update (Server.Modify privilege): masked
or empty secrets mean unchanged, null removes the option, the
response carries the new values plus restart_required, and a
settings.updated notification is emitted. New
Server.Audit/Server.Modify privileges are seeded into the
Administrator role at table creation.
Appliance fields that describe the appliance (vendor information, default
credentials, installation instructions...) were dropped when installing a
template. Keep them in a new appliance_metadata JSON column on the
templates table, filled by the appliance-to-template conversion for both
registry v1-6 and v8 (version level values override the appliance level
ones). The nested schema allows extra fields so future registry fields
persist without a migration.
Common template field (schema + templates table column + Alembic
migration) holding the Netmiko device type (e.g. 'cisco_xr', 'nokia_srl')
so Netmiko/Nornir based tooling can look up how to reach a node's CLI
without hard-coded vendor mappings. Free-form lowercase string on
purpose: Netmiko's platform list evolves independently of GNS3.
The extra_configs schema field needs a column on the docker_templates table
to actually round-trip through the controller DB (the schema alone is
accepted but dropped by the SQLAlchemy model mapping). Add the JSON column
and an Alembic migration so existing databases get it on upgrade.
Reading the entire DB file into OS page cache eliminates the 8-14s
cold-start penalty on the first ORM query (users/templates/api_keys).
Previous SELECT 1 only warmed the connection pool, not the file cache.
