Check installation script exit codes

[LegacyAngel2K9]

Summary

• Check the installation container wait response and fail installs when the script exits with a non-zero status.
• Preserve the installation log before cleaning up a failed installer container.
• Publish a clear failure message to the installation stream.
• Add regression coverage for successful exits, non-zero exits, command-not-found, and Docker wait errors.

Root cause

InstallationProcess.Execute waited for the installer container to stop but discarded the returned WaitResponse. As a result, an installation script that exited with status 1 (or any other non-zero status) was treated as successful and the Panel received successful: true.

Impact

Failed egg installation scripts are now reported as failed to the Panel through the existing install status request, while the installer output remains available for diagnosis.

Validation

• go test ./... with Go 1.25.12 in Docker
• go test -race ./... with Go 1.25.12 in Docker
• Focused regression test with Go 1.26.5 in Docker

Closes #88

Summary by CodeRabbit

• Bug Fixes

  • Installation failures now correctly report container execution and wait errors.
  • Nonzero installation exit statuses are surfaced as failures instead of success.
  • Failed installations emit failure events, while completion is reserved for successful runs.
  • Unused containers are cleaned up when execution does not start successfully.

• Tests

  • Added coverage for successful waits, nonzero exit codes, and wait failures with or without error messages.

Learning: In the server package, when quotas are enabled via config.Get().System.Quotas.Enabled, the disk space check using used >= s.DiskSpace() does not require a special guard for unlimited-disk scenarios (DiskSpace() <= 0). The filesystem handles such cases, so the existing check is sufficient. Apply this pattern to similar quota-related disk checks in the server package and ensure tests/docs reflect that unlimited-disk behavior is governed by the filesystem, not by an extra guard in code.

📝 Walkthrough

Walkthrough

Installation execution now preserves errors after cleanup. Container wait failures and nonzero script exit codes produce failure events and descriptive errors. Completion events require a successful zero exit status. Tests cover wait error formatting and failure event publication.

Changes

Installation error handling

Layer / File(s)	Summary
Execution error propagation server/install.go	Run preserves execution errors, removes the installer container when no container ID exists, and returns the execution result after cleanup.
Wait failure reporting and validation server/install.go, server/install_test.go	Container wait errors and nonzero exit codes produce failure events and descriptive errors. Completion events require a zero exit status. Tests cover success, failure messages, and failure event publication.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 49127

The installation status and log-handling changes are merge-ready after normal checks and review; no actionable merge-blocking risk remains.

Poem

A rabbit checks the install trail,
Zero exits mean success, not fail.
Wait errors now make failures clear,
Cleanup still happens without fear.
Tests verify each message here.

publish the same DaemonMessageEvent failure notification before returning the
Docker wait error, matching the existing failure-message behavior on other error
paths. Add a regression test that exercises the eChan path and verifies the
failure event is emitted.
