Introduce post_progress_to_api() in alpine-install.func and install.func to send a lightweight, fire-and-forget telemetry ping (HTTP POST) that updates an existing telemetry record to "configuring" when DIAGNOSTICS=yes and RANDOM_UUID is set. The function is non-blocking (curl -m 5, errors ignored) and is invoked during container setup and after OS updates to signal active progress. Also adjust api_exit_script() in build.func to report success (post_update_to_api "done" "0") for cases where the script exited normally but a completion status wasn't posted, instead of reporting failure.
* Ensure API update is sent on script exit
Add exit-time telemetry handling across scripts to avoid orphaned "installing" records. Introduce local exit_code capture in api_exit_script and cleanup handlers and, when POST_TO_API_DONE is true but POST_UPDATE_DONE is not, post a final status (marking failures on non-zero exit codes, or marking done/failed in VM cleanups based on exit code). Changes touch misc/build.func, misc/vm-core.func and various vm/*-vm.sh cleanup functions to reliably send post_update_to_api on normal or early exits.
* Update api.func
* fix(telemetry): add missing exit codes to explain_exit_code()
- Add curl error codes: 4, 5, 8, 23, 25, 30, 56, 78
- Add code 10: Docker/privileged mode required (used in ~15 scripts)
- Add code 75: Temporary failure (retry later)
- Add BSD sysexits.h codes: 64-77
- Sync error_handler.func fallback with canonical api.func
Replace the final '| head -1' in both install and ct scripts with 'awk 'NR==1'' to pick the first matching Teamspeak release line. In the ct script the previous temporary toggling of pipefail was also removed, simplifying the command. This improves compatibility and reduces reliance on an extra utility in minimal environments.
- Remove legacy error_handler(), on_exit(), on_interrupt(), on_terminate() and set/trap definitions from alpine-install.func (already provided by error_handler.func which is sourced on line 10)
- The local error_handler() expected positional args as required, but catch_errors() sets trap as 'error_handler' (without args), causing unbound variable error with set -u (nounset)
- error_handler.func uses default values which is set -u safe
- Also align legacy trap in install.func network_check() to standard format
Fixes#11929
Update ct/jellyseerr.sh and ct/overseerr.sh to switch the container update handler to the Seerr script. The here-doc now uses a single-quoted EOF to avoid shell expansion and includes an explicit shebang for the generated /usr/bin/update. Instead of auto-executing the new update script, the code now informs the user to run 'update' again and exits (overseerr exits with 0). Also includes minor whitespace cleanup (removed trailing spaces on cd lines). This prevents unexpected immediate execution and ensures the generated script runs with the intended shell.
