From 12e5f97f59eeea537b2d057f836d2bab0850780a Mon Sep 17 00:00:00 2001 From: shankar0123 Date: Thu, 30 Apr 2026 14:56:23 +0000 Subject: [PATCH] feat(apache): atomic deploy + post-deploy TLS verify + rollback + ValidateOnly + test-depth uplift to 34 tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 5 of the deploy-hardening I master bundle. Mirrors the Phase 4 NGINX template for Apache httpd. Test count lifts 3 → 34 (above the prompt's >=30 target; matches and slightly exceeds the IIS bar). Apache-specific quirks codified in apache.go: - Validate command convention is `apachectl configtest` (NOT `apachectl -t` — that flag exists but configtest is the documented operator-facing form). - Reload command convention is `apachectl graceful` for zero- downtime worker swap (NOT `apachectl restart` which drops in-flight TLS sessions). - Per-distro user defaults: Debian/Ubuntu apache2, RHEL/CentOS apache, Alpine httpd. pickFirstExistingUser walks the list and picks the one that resolves on the host; falls back to no-chown when none exist (cross-distro portability without operator config; same approach as nginx). - Default key file mode 0600 for back-compat with operators relying on the historical hard-coded value (matches the pre-Phase-5 implementation behavior). DeployCertificate refactor: - Replaces the duplicated os.WriteFile chain with deploy.Apply. - PreCommit runs the operator's ValidateCommand via the test seam (which wraps `sh -c ` in production). - PostCommit runs ReloadCommand the same way. - Post-deploy TLS verify (frozen-decision-0.3 default ON when Endpoint is configured): probes the configured target, compares leaf cert SHA-256 against deployed bytes, retries with exponential backoff (default 3 attempts / 2s backoff for load-balanced targets). - Rollback wires: reload-fail → restore backups + retry reload; verify-fail → restore backups + reload again. Second-failure surfaces ErrRollbackFailed for operator-actionable triage. ValidateOnly real implementation replaces the Phase 3 stub. Returns ErrValidateOnlyNotSupported when no ValidateCommand configured; otherwise runs the validate-with-the-target command without touching the live cert. Test seams (SetTestRunValidate / SetTestRunReload / SetTestProbe) allow tests to skip exec without `apachectl` on PATH; mirror the nginx pattern. Tests (34 total: 31 in apache_atomic_test.go + 3 pre-existing in apache_test.go): - Atomic invariants (happy, validate-fail-no-files-changed, reload-fail-rollback, rollback-also-fail-escalation) - SHA-256 idempotency (full skip + partial-mismatch full-deploy) - Post-deploy verify (match-success, mismatch-rollback, dial-timeout-rollback, retries-until-match, retries-exhausted-rollback, no-endpoint-skips, disabled-skips) - Ownership / mode preservation (existing-mode, override-wins, default-key-0600, default-cert-0644) - Backup retention (keeps-N, disabled-no-backups, backup-created) - Concurrency (same-paths-serialize) - ValidateOnly (happy, fails, no-command-sentinel, stderr-in-error) - Edge cases (no-chain, no-key, ctx-cancelled, verify-rollback- reload, deployment-id-prefix, metadata-populated) Coverage: Apache 86.6% (above the >=85% prompt bar). Race detector clean. golangci-lint v2.11.4 clean. Smoke test connectorsAtPhase3 list shrunk from 12 to 11 entries (apache removed; nginx + apache now have real impls). Phase 6 next: HAProxy (combined PEM atomic write + `haproxy -c -f` validate + uplift 3 → >=30). --- internal/connector/target/apache/apache.go | 469 ++++++++++---- .../target/apache/apache_atomic_test.go | 607 ++++++++++++++++++ .../connector/target/apache/validate_only.go | 18 - .../target/validate_only_smoke_test.go | 7 +- 4 files changed, 955 insertions(+), 146 deletions(-) create mode 100644 internal/connector/target/apache/apache_atomic_test.go delete mode 100644 internal/connector/target/apache/validate_only.go diff --git a/internal/connector/target/apache/apache.go b/internal/connector/target/apache/apache.go index 52ab74f..9547911 100644 --- a/internal/connector/target/apache/apache.go +++ b/internal/connector/target/apache/apache.go @@ -1,204 +1,428 @@ +// Package apache implements the Apache httpd target connector. +// As of the deploy-hardening I master bundle Phase 5, Apache +// follows the canonical pattern established by NGINX (Phase 4): +// atomic-write all files via internal/deploy.Apply, run +// `apachectl configtest` as PreCommit, run `apachectl graceful` as +// PostCommit, post-deploy TLS handshake to verify the new cert is +// being served, rollback on any failure. +// +// Apache-specific quirks codified here: +// +// - Validate command is `apachectl configtest` (NOT `apachectl -t` +// — that flag exists but the operator-facing convention is +// configtest). +// - Reload command is `apachectl graceful` for zero-downtime +// reload (NOT `apachectl restart` which drops in-flight TLS +// sessions). +// - Separate cert / chain / key files (vs HAProxy's combined +// PEM blob). package apache import ( "context" + "crypto/sha256" + "encoding/base64" + "encoding/hex" "encoding/json" + "errors" "fmt" "log/slog" "os" "os/exec" + "os/user" "path/filepath" + "strings" "time" "github.com/shankar0123/certctl/internal/connector/target" + "github.com/shankar0123/certctl/internal/deploy" + "github.com/shankar0123/certctl/internal/tlsprobe" "github.com/shankar0123/certctl/internal/validation" ) -// Config represents the Apache httpd deployment target configuration. -// This configuration is used on the agent side to deploy certificates to Apache. +// Config represents the Apache httpd deployment target +// configuration.
