Maxim Shulga f3804b7e2e Bound daemon startup and shutdown and exit with a useful code
start_daemon and stop_daemon polled "while True" with no bound, and no
seaf-cli exit code was checked. A daemon that failed to start left the
container spinning forever with nothing pointing at the cause, and there was
no signal handling, so "docker stop" waited the full 10 second grace period
and then SIGKILLed the process with the daemon still running.

Readiness polling is now bounded by DAEMON_START_TIMEOUT and
DAEMON_STOP_TIMEOUT. The stop timeout is 8 seconds so a graceful shutdown
fits inside the docker stop grace period, and a test asserts that relation.

SIGTERM and SIGINT raise GracefulShutdown, and the lifecycle moved into
start.run(), which always stops the daemon on the way out and returns the
process exit code: 0 on a clean finish or a stop signal, 1 on a daemon or
configuration failure.

seaf-cli exit codes are checked. A failed sync is reported per library and
does not stop the remaining libraries, since one bad library should not take
the container down.

Verified in the built image: "docker stop" now returns in 0s with exit code 0
and the daemon stopped, against 10s and exit 137 before. A daemon that cannot
start exits 1 with the failing command and its exit code in the log.

Also bumps actions/setup-python to v7, which clears the last Node 20
deprecation warning; v7 only drops the unused pip-install input.

# docker-seafile-client
Docker image for [Seafile CLI client](https://help.seafile.com/syncing_client/linux-cli/).
Image on Docker Hub:
[snegov/seafile-client](https://hub.docker.com/r/snegov/seafile-client).
### Docker-compose example:
Also available as a ready-to-use [`compose.example.yaml`](compose.example.yaml).
```yaml
services:
seafile-client:
restart: always
image: snegov/seafile-client:0.0.13
environment:
LIBRARY_ID: "79867cbf-2944-488d-9105-852463ecdf9e:my_library"
SERVER_HOST: seafile.example.com
USERNAME: user
PASSWORD: password
SEAFILE_UID: 1000
SEAFILE_GID: 100
hostname: dsc
volumes:
- /home/johndow/seafile:/dsc/seafile
- sync-data:/dsc/seafile-data
container_name: seafile-client
volumes:
sync-data:
```
### Environment variables:
- `LIBRARY_ID` - library to sync, ID or name. Multiple libraries could be
separated by colon `:`.
- `SERVER_HOST` - hostname of your Seafile server, eg: _seafile.example.com_.
If you're using non-standard port, you can specify it here,
eg: _seafile.example.com:8080_.
- `USERNAME` / `PASSWORD` - credentials to access Seafile server.
- `SEAFILE_UID` / `SEAFILE_GID` - UID/GID of user inside container. You can
use it to set permissions on synced files. Default values are _1000_ / _1000_.
- `DELETE_CONFIRM_THRESHOLD` - represents the number of files that require
confirmation before being deleted simultaneously. Default value is _500_.
- `DISABLE_VERIFY_CERTIFICATE` - set to _true_ to disable server's certificate
verification. Default value is _false_.
- `UPLOAD_LIMIT` / `DOWNLOAD_LIMIT` - upload/download speed limit in B/s
(bytes per second). Default values are _0_ (unlimited).
### Volumes:
- `/dsc/seafile-data` Seafile client data directory (sync status, etc).
- `/dsc/seafile` Seafile libraries content.
### Some notes
`LIBRARY_ID` could be library ID or library name. Library ID is a 36-character
string, which is a part of URI when you open library in webUI. Library name is
a name you gave to library when you created it.
Libraries will be synced in subdirectories of `/dsc/seafile` directory inside
container. You can mount it to host directory to access files.
The subdirectory is named after the library, with whitespace replaced by
underscores. A library is skipped with a warning when its name cannot be a
directory of its own: an empty name, `.`, `..`, or a name containing `/`. Two
libraries whose names would produce the same directory both get their library
ID appended, so they never share one. Everything is created under the
libraries directory (`/dsc/seafile`, or the deprecated `/data` when that
exists); a library name can never place it elsewhere.
The container stops gracefully on `docker stop`: it shuts the Seafile daemon
down and exits with code 0. It exits with a nonzero code and an explanatory
message when the daemon fails to start or stop within its timeout, instead of
waiting forever.
`hostname` parameter is optional, but it's recommended to set it to some unique
value, it will be shown in Seafile webUI as client name (`terminal-dsc` in
given example).
`sync-data` volume is optional too, but it's recommended to use it. Otherwise,
sync status will be lost when container is recreated.
At the moment there is no suitable way to confirm deletion of large number of
files. So, if you're going to delete a lot of files, you should set
`DELETE_CONFIRM_THRESHOLD` to some larger value.
