Pull request overview
This PR addresses issue #957 by hardening production configuration and making the GitHub webhook deploy flow safer on non-Linux platforms, reducing crashes and preventing insecure production startups.
Changes:
- Add a production-only validation requiring
SECRET_KEYto be set via environment variable. - Move
ENVIRONMENTinitialization earlier to avoid use-before-definition during settings evaluation. - Gate
systemctl restartto Linux and add basic exception/timeout handling for the restart step.

Adds production validation for SECRET_KEY and reorders ENVIRONMENT definition to support that validation safely. |

- Around line 53-57: In production, tighten SECRET_KEY validation: when
ENVIRONMENT == "production" read SECRET_KEY via env.str (avoid silently falling
back to the insecure default), trim and reject empty or whitespace-only values
and also explicitly reject the known insecure fallback string currently used; if
invalid, raise ValueError. Update the check around ENVIRONMENT, SECRET_KEY and
env.str to validate the trimmed value against "" and the insecure default
constant and raise an error so the app cannot start with an unsafe key.
In `@web/views.py`:
- Around line 1120-1127: The subprocess.run call currently uses check=False so
non-zero exit codes are ignored; update the logic around the subprocess.run(...)
that restarts the service to detect non-zero return codes (either set check=True
or inspect the CompletedProcess.returncode) and treat failures as deployment
errors by setting the ok flag to False and appending a descriptive message to
log_lines (include stdout/stderr from the CompletedProcess for diagnostics);
also keep existing except handlers for FileNotFoundError and TimeoutExpired but
ensure any non-zero returncode is logged and causes the handler to return a
failure response instead of marking deployment successful.

narrow PATH trust by validating systemctl_path against a whitelist of trusted
absolute locations (e.g., /bin/systemctl, /usr/bin/systemctl) and fallback to a
safe default only if the file exists and is executable before calling
subprocess.run (the call that restarts "education-website"); also broaden the
except clause around the subprocess.run invocation to catch OSError (or
Exception subclasses like PermissionError) instead of only FileNotFoundError and
subprocess.TimeoutExpired, and ensure you still append the error to log_lines
and set ok = False on failure.

- Line 1133: The call to subprocess.run in the proc = subprocess.run(...)
expression is triggering Ruff S603; since this invocation uses trusted absolute
paths and constant args, add an inline Ruff noqa suppression on that expression
(e.g., append "# noqa: S603 - uses trusted absolute path and constant args" to
the line) so the linter is satisfied and include the brief rationale in the
comment; locate the subprocess.run usage in the web/views.py view and add the
inline suppression directly on that line.
