Description

msfdb init can provision users before PostgreSQL is ready. If startup times out, a later init can mistake the unfinished database for a completed installation and skip provisioning.

Wait for PostgreSQL readiness using pg_ctl -w -t 60, apply authentication rules before startup, and track initialization through migration completion. Retry interrupted setup using saved settings without deleting existing data; leave incomplete initdb output and directories without initialization markers for inspection.

Production migrations fail without a Rails key or permission to write their schema dump into the installation. Give the migration subprocess a temporary key when SECRET_KEY_BASE is unset and discard its schema dump. Preserve #18442's Windows fix by leaving startup output uncaptured.

Verification

1. Run SPEC_HELPER_LOAD_METASPLOIT=false bundle exec rspec spec/lib/msfdb_helpers/pg_ctl_spec.rb; expect 21 examples and no failures.
2. In a disposable profile, run msfdb init --component database --use-defaults, then msfconsole -qx 'db_status; exit'; expect successful initialization and a connection.
3. Repeat msfdb init; it should recognize the completed database without provisioning again.

Test evidence

The 21 helper specs pass on macOS and Windows. Recovery, fresh and repeated initialization also pass against installed runtimes, with 164 migrations verified by SQL and the installed schema unchanged.

All ten package jobs passed with Ruby 3.4.12 on macOS 14 arm64, macOS 15 x86_64, Windows Server 2022 and Linux. They build 809e1587 plus migration correction 711d40bb and verify its source digests. ARMv7 covers build and package health only.

Summary

Summary by CodeRabbit

• Bug Fixes
  • Database initialization resumes incomplete setup and reports failures when initialization, migrations, or PostgreSQL startup do not complete successfully.
  • PostgreSQL startup waits for readiness, and attempts to start an already-running or incompletely initialized database are handled safely.
  • Invalid database configuration, including missing credentials or an invalid production port, is rejected.
  • Existing database roles and databases are checked during provisioning; role credentials and permissions are updated as needed.
• Improvements
  • Initialization progress is coordinated to prevent overlapping setup attempts.

Database initialization now tracks progress and resumes eligible interrupted setup. Startup waits for PostgreSQL readiness. The msfdb command validates database configuration and migration results. Role and database provisioning now uses PostgreSQL connections.

Changes: PostgreSQL initialization and provisioning

Layer / File(s)	Summary
Track and resume initialization lib/msfdb_helpers/db_interface.rb, lib/msfdb_helpers/pg_ctl.rb, msfdb, spec/lib/msfdb_helpers/pg_ctl_spec.rb	The database interface adds initialization wrapper and pending-state methods. PgCtl records progress, locks initialization, resumes eligible incomplete setup, and clears the marker after success or database-directory deletion. msfdb runs initialization through the driver wrapper and writes credentials during setup when supported. Specs cover initialization ordering, interrupted setup, locking, retry behavior, and failure states.
Gate startup on cluster state lib/msfdb_helpers/pg_ctl.rb, spec/lib/msfdb_helpers/pg_ctl_spec.rb	PgCtl#start rejects pending initialization and waits for pg_ctl readiness. PgCtl#status reports NEEDS_INIT for pending setup or a directory without PG_VERSION. Specs cover startup arguments, process results, and cluster-state behavior.
Provision roles and databases lib/msfdb_helpers/pg_ctl.rb, spec/lib/msfdb_helpers/pg_ctl_spec.rb	Provisioning checks for existing roles and databases, updates role settings using quoted identifiers and escaped passwords, and creates missing databases through the application role. Specs cover existing roles, database creation, and propagated errors.
Validate configuration and migration results msfdb	load_db_config validates required production and test fields and the production port. Invalid settings return false. Database migration failure raises PG::Error.

Merge Risk: Minimal · up to 711d4

This change makes msfdb init wait for PostgreSQL to accept connections and resume interrupted setup. It also surfaces configuration and migration failures instead of ignoring them. No actionable merge-blocking issue was found in the supplied change.

Review details

Systems and components

• observed — lib (service) was modified; 2 changed files map to changed impact.
• observed — msfdb (service) was modified; 1 changed file maps to changed impact.
• observed — spec (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in lib/msfdb_helpers/db_interface.rb: Added with_initialization, which yields to its block, and initialization_pending?, which returns false; comments document their initialization-related roles.
• observed — Modified behavior in lib/msfdb_helpers/pg_ctl.rb: PgCtl#init now resumes only a pending initialization marked setup, stopping a running incomplete cluster or raising on invalid progress or stop failure. For a new cluster it writes initdb and then setup markers and raises if initdb fails. It yields caller configuration work before proceeding with cluster setup.
• observed — Modified behavior in lib/msfdb_helpers/pg_ctl.rb: Initialization now writes client-authentication configuration before starting PostgreSQL, uses start_database, and raises if the server does not become ready; successful setup returns true. This replaces the earlier unconditional start path and moves authentication configuration ahead of user creation and startup completion.
• observed — Modified behavior in lib/msfdb_helpers/pg_ctl.rb: Adds with_initialization, which takes a nonblocking exclusive lock at @db.lock, raises if another initializer holds it, yields initialization work, and removes a pending marker after success. Adds initialization_pending? to test for the marker file.

Full details: Title check

Explanation

The title "Wait for PostgreSQL readiness and recover failed setup" matches the main changes. The PR makes PgCtl#init and startup wait for pg_ctl -w readiness instead of polling, and it adds marker-based resumption of interrupted initialization. The title names both the readiness wait and the failed-setup recovery. It does not name the affected component (msfdb / pg_ctl helper), but the technical writing requirement only asks for the change and component, so the title is mostly descriptive.

Full details: Pr Description And Verification

Explanation

The description explains the failure and the changes. It gives concrete commands, expected outcomes, actual focused-spec and PostgreSQL results, platform and version setup, and the pending package-revalidation limit. It also describes the original failure sequence: startup can time out, PostgreSQL can start later, and a second msfdb init can skip provisioning.

- Line 115: Update the startup handling around startup_status so a timed-out
pg_ctl start reconciles a server that becomes ready afterward, either stopping
it or securing its authentication before returning. Ensure the
timeout-then-ready path does not leave the cluster unattended and allows a
subsequent msfdb init to complete setup.

Package testing caught two more migration failures: Rails needs a production key, and its schema dump tries to write into the installation. I've scoped a temporary key and a null schema-dump destination to the migration command.

All ten package jobs now pass, including fresh-install database checks on macOS, Windows and Linux. Recovery, fresh initialization and repeated initialization also passed on macOS and Windows.
