Both accepted a native install and then drove `docker compose` in a directory
with no compose file, so the user got "no configuration file provided" rather
than an explanation. They now refuse with what to do instead, and restore
refuses before it reads the archive or stops anything.
`open` built its address from stack.url, which honours DOCSGPT_BIND, while the
native units always bind 127.0.0.1: with a LAN bind it handed the browser an
address nothing was listening on. status had the same mismatch and was fixed
with it; both now go through one helper so they cannot drift apart again.
From the outside-diff findings on #2800:
- install.json is written before the services are installed and started. A
service that fails to start used to leave units behind in a directory that
status, down and uninstall no longer recognised as a native install, so
nothing could clean them up.
- systemd stop and removal propagate failures: `down` reporting success while
the unit still runs, or `uninstall` dropping the unit file and the record
while systemd still runs the service, is worse than an error. Removing a unit
that is already gone stays harmless.
- WorkingDirectory and each Environment value are quoted and escaped for
systemd. `--dir` takes a free-form path, and one with a space in it is not
hypothetical: this checkout lives in one.
- Native status checks and prints http://localhost:<port>, which is what the
units bind. With a LAN DOCSGPT_BIND it used to poll an address nothing
listened on and call a healthy install dead.
Refusing to write the service units when `docsgpt` is not on PATH was wrong. A
package installed in a virtualenv is runnable whether or not its console script
is on PATH, and CI runs pytest as `python -m pytest`, where argv[0] is a module
file: the refusal failed thirteen native tests there.
The launcher now prefers the command on PATH, resolved to an absolute path
since PATH can hold relative entries, then an argv[0] that can be executed, and
otherwise this interpreter with `-m docsgpt`, which works wherever the package
is importable. `python -m docsgpt` became an entrypoint of its own and has a
test that runs it.
From review of #2800:
- systemd `enable --now` starts nothing when the unit is already active, so a
second `up --native` kept the old ExecStart and left the API on its previous
port. start enables and then restarts, as the launchd path already did by
booting the job out first.
- An explicit `home` now wins over XDG_CONFIG_HOME, which is what callers pass
it for.
- The ExecStart program must be a real executable: when `docsgpt` is not on
PATH, sys.argv[0] is accepted only if it can be run, and otherwise the
failure is raised before any unit is written.
- `up --native` over a directory holding a Docker install now refuses and says
how to proceed, instead of starting native services beside containers that
down, status and uninstall would no longer see.
- Docs: without a terminal only --postgres-uri is required, and the Windows
fallback names `docsgpt beat`, which the worker cannot embed there.
SystemdServices was the least covered part of the module and cannot be run on
this machine, so it now has tests for install, start, stop, remove, is_running
and a failing systemctl.
Run DocsGPT without Docker: the API and the worker each become a service
on the machine itself, a launchd agent on macOS and a systemd user unit
on Linux, pointed at a PostgreSQL and a Redis that already run.
`docsgpt up --native --postgres-uri ... --redis-url ...` writes the same
.env a Docker install uses, applies the migrations and starts both
services. status, logs, down and uninstall work on a native install the
same way they do on a Docker one, and never touch the database or Redis:
they were the user's to begin with.
One Redis URL covers the broker, the result backend and the cache on
three consecutive databases, starting at the one the URL names, so a
Redis that already holds something else can be shared.
Windows has neither service manager, so native mode refuses it and says
what to do instead.
