From e313a6b9766263e3714c7efdbb5c0ca51a35cdfe Mon Sep 17 00:00:00 2001 From: tis24dev Date: Fri, 16 Jan 2026 17:32:19 +0100 Subject: [PATCH 01/17] Add tests for orchestrator, support, and tui modules Introduces new test files for encryption, prompts, restore workflow, selective menu, support, and abort context functionalities. Refactors orchestrator/encryption.go to allow mocking terminal checks, and support.go to allow mocking email notifier creation for improved testability. Adds a stopHook to tui.App for controlled stopping in tests. --- internal/orchestrator/.backup.lock | 4 +- internal/orchestrator/encryption.go | 3 +- internal/orchestrator/encryption_more_test.go |

7750912c0fb359e7cd2d4bdf887ac1e107a291ec Mon Sep 17 00:00:00 2001 From: tis24dev Date: Sat, 17 Jan 2026 12:16:26 +0100 Subject: [PATCH 05/17] Add comprehensive tests for MAC, directory, and security logic Added extensive unit tests to identity_test.go for MAC address handling, interface ranking, system data generation, and edge cases. Expanded directory_recreation_test.go with tests for storage/datastore config parsing, directory creation, error propagation, and ZFS detection. Added security_test.go tests for ownership/permission checks, config-driven logic, and error handling. These tests improve coverage and robustness for identity, orchestrator, and security modules. --- internal/identity/identity_test.go | 1005 +++++++++++ internal/orchestrator/.backup.lock | 4 +-

The tests improve code reliability by simulating various failure scenarios, file system errors, and user interactions. --- internal/orchestrator/--progress | 1 + internal/orchestrator/.backup.lock | 4

Implements network configuration safe apply with a transactional rollback timer, health checks, NIC name repair, and diagnostics capture. Adds network inventory collection, network health/preflight validation, and CLI workflow for applying/restoring network config with rollback.

shadowing guard and NIC naming override detection Introduces cluster shadowing guard to prevent direct restoration of /etc/pve paths during cluster recovery, with sanitization logic and tests. Adds detection and reporting of persistent NIC naming override rules (udev/systemd) to network_apply and TUI workflows, including user prompts and detailed logging. Enhances safe cluster apply to handle node mismatches, prompt for source node selection, and improves logging and test coverage for restore scenarios. --- internal/orchestrator/.backup.lock | 4 +- .../orchestrator/cluster_shadowing_guard.go | 52 +++ .../cluster_shadowing_guard_test.go | 59 ++++ internal/orchestrator/network_apply.go | 37 ++ internal/orchestrator/nic_naming_overrides.go | 330 ++++++++++++++++++ .../orchestrator/nic_naming_overrides_test.go | 67 ++++ internal/orchestrator/restore.go | 264 +++++++++++++- .../restore_coverage_extra_test.go | 121 +++++++ internal/orchestrator/restore_tui.go | 105 +++++- 9 files changed, 1013 insertions(+), 26 deletions(-) create mode 100644 internal/orchestrator/cluster_shadowing_guard.go create mode 100644 internal/orchestrator/cluster_shadowing_guard_test.go create mode 100644 internal/orchestrator/nic_naming_overrides.go create mode 100644 internal/orchestrator/nic_naming_overrides_test.go diff --git a/internal/orchestrator/.backup.lock b/internal/orchestrator/.backup.lock index 9b1dc29..d1d3411 100644 --- a/internal/orchestrator/.backup.lock +++ b/internal/orchestrator/.backup.lock @@ -1,3 +1,3 @@ -pid=969171 +pid=1045739 host=pve -time=2026-01-17T15:48:35+01:00 +time=2026-01-17T18:01:59+01:00 diff --git a/internal/orchestrator/cluster_shadowing_guard.go b/internal/orchestrator/cluster_shadowing_guard.go new file mode 100644 index 0000000..22c91bb --- /dev/null +++ b/internal/orchestrator/cluster_shadowing_guard.go @@ -0,0 +1,52 @@ +package orchestrator + +import "strings" + +const ( + etcPVEPrefix = "./etc/pve" + etcPVEDirPrefix = "./etc/pve/" +) + +func sanitizeCategoriesForClusterRecovery(categories []Category) (sanitized []Category, removed map[string][]string) { + removed = make(map[string][]string) + sanitized = make([]Category, 0, len(categories)) + + for _, category := range categories { + if len(category.Paths) == 0 { + sanitized = append(sanitized, category) + continue + } + + kept := make([]string, 0, len(category.Paths)) + for _, path := range category.Paths { + if isEtcPVECategoryPath(path) { + removed[category.ID] = append(removed[category.ID], path) + continue + } + kept = append(kept, path) + } + + if len(kept) == 0 && len(removed[category.ID]) > 0 { + continue + } + + category.Paths = kept + sanitized = append(sanitized, category) + } + + return sanitized, removed +} + +func isEtcPVECategoryPath(path string) bool { + normalized := strings.TrimSpace(path) + if normalized == "" { + return false + } + if !strings.HasPrefix(normalized, "./") && !strings.HasPrefix(normalized, "../") { + normalized = "./" + strings.TrimPrefix(normalized, "/") + } + if normalized == etcPVEPrefix || normalized == etcPVEDirPrefix { + return true + } + return strings.HasPrefix(normalized, etcPVEDirPrefix) +} diff --git a/internal/orchestrator/cluster_shadowing_guard_test.go b/internal/orchestrator/cluster_shadowing_guard_test.go new file mode 100644 index 0000000..00336da --- /dev/null +++ b/internal/orchestrator/cluster_shadowing_guard_test.go @@ -0,0 +1,59 @@ +package orchestrator + +import "testing" + +func TestSanitizeCategoriesForClusterRecovery_RemovesEtcPVEPaths(t *testing.T) { + categories := []Category{ + { + ID: "pve_jobs", + Name: "PVE Backup Jobs", + Paths: []string{"./etc/pve/jobs.cfg", "./etc/pve/vzdump.cron"}, + }, + { + ID: "storage_pve", + Name: "PVE Storage Configuration", + Paths: []string{"./etc/vzdump.conf"}, + }, + { + ID: "mixed", + Name: "Mixed", + Paths: []string{ + "./etc/pve/some.cfg", + "./etc/other.cfg", + "etc/pve/legacy.conf", + "/etc/pve/abs.conf", + "./etc/pve2/keep.conf", + }, + }, + } + + sanitized, removed := sanitizeCategoriesForClusterRecovery(categories) + + if len(removed["pve_jobs"]) != 2 { + t.Fatalf("expected 2 removed paths for pve_jobs, got %d", len(removed["pve_jobs"])) + } + if len(removed["mixed"]) != 3 { + t.Fatalf("expected 3 removed paths for mixed, got %d", len(removed["mixed"])) + } + if _, ok := removed["storage_pve"];
