* fix(iam): prevent transient IAM walk timeout from crashing startup
IAM startup performs a blocking full metadata walk on `.rustfs.sys/config/iam/`.
When that distributed walk times out (e.g. disk pressure after cluster reboot),
the old code treated the failure as fatal and exited the process, causing a
systemd restart loop.
Changes:
- Add `startup_iam.rs`: attempt IAM init, enter degraded mode on failure,
spawn background retry task with exponential backoff (5s→10s→20s→30s cap)
- Log level escalates to ERROR after 12 retries (~5 min) to aid diagnosis
- `/health/ready` returns 503 until IAM recovers; IAM-dependent ops return
`IamSysNotInitialized` (existing fail-closed behavior preserved)
- Fix admin path boundary matching: `/minio/administrator` no longer falsely
matches as admin prefix
- Normalize Content-Length: 0 for admin GET requests with empty body
Fixes#3175
* fix(iam): move constant assertion into const block
Fixes clippy::assertions-on-constants warning on
IAM_RETRY_ESCALATION_THRESHOLD assertion.
* fix(iam): address PR review comments
- Replace OnceLock with AtomicU64 sentinel for test isolation;
add reset_test_failure_counter() for integration tests
- Use u32::try_from() instead of `as u32` narrowing cast in
compute_backoff_interval
- Rename misleading test; update to verify finalize retry behavior
- Restructure spawn_iam_recovery_task into init-retry and
finalize-retry phases so transient readiness failures are retried
instead of leaving the server permanently degraded
* fix(iam): gate test hooks behind debug_assertions
- reset_test_failure_counter() now stores sentinel (u64::MAX) to
correctly trigger env var re-read on next call
- RUSTFS_TEST_IAM_FAIL_INIT_ATTEMPTS only honored in debug builds
- RUSTFS_TEST_IAM_RETRY_INTERVAL_MS only honored in debug builds
* test(iam): cover deferred bootstrap recovery
Add a dedicated embedded deferred-IAM integration test in a separate test binary to avoid process-global startup collisions.
Strengthen startup IAM recovery coverage with focused unit tests and keep the existing embedded smoke test isolated while carrying the manual test license header update in the same change set.
* fix(startup): tighten deferred IAM recovery path
Adopt follow-up review feedback by silencing misleading app-context warnings after IAM recovery, reusing boundary-aware path prefix checks in the readiness gate, and tying deferred IAM recovery retries to server shutdown tokens.
Keep the deferred IAM embedded integration coverage and startup recovery unit coverage green after the follow-up hardening.
* refactor(startup): simplify IAM recovery task
Collapse the deferred IAM recovery implementation back to a concrete production flow instead of keeping boxed callback seams in the runtime path.
Keep only stable backoff unit coverage in startup_iam and rely on the embedded deferred bootstrap integration test for end-to-end recovery behavior.
* refactor(startup): trim IAM recovery test scaffolding
Keep the concrete deferred IAM recovery path intact while removing bulky test-only async loop scaffolding from startup_iam.
Retain the stable backoff unit checks and rely on the embedded deferred bootstrap integration test for end-to-end recovery coverage.
* fix: apply code review improvements from PR #3188 review
- Simplify RecoveryFuture type alias by removing unnecessary lifetime
- Fix finalize_iam_recovery to return Err if app context unavailable
- Update bootstrap_or_defer_iam_init doc comment to reflect Err case
- Use boundary-aware has_path_prefix for admin path matching in utils.rs
- Add test for adminx boundary rejection in utils.rs and layer.rs
- Improve embedded deferred IAM test with timeout wrapper
* style: merge has_path_prefix import into existing use block
* fix(iam): address final review follow-ups
- fix main startup readiness publication to pass ServiceStateManager correctly
- centralize IAM test env keys in rustfs_config and reuse them in runtime/tests
- keep deferred IAM bootstrap validation aligned with the final review fixes
* fix: isolate listing timeouts from drive health
Keep walk_dir scanner timeouts request-scoped instead of marking local drives faulty.
Add regression coverage for follow-up bucket info, set-level list_path, and system-prefix listings after prior walk timeouts.
* test(iam): gate deferred bootstrap test to debug
Align the deferred IAM embedded integration test with debug-only IAM fault injection hooks so release-profile runs do not assert deferred bootstrap behavior that cannot be triggered.
* test(ecstore): bound prior walk timeout regressions
- set walk_dir stall timeout explicitly in prior-timeout listing tests
- keep the system-prefix follow-up listing scoped to the same base dir
- assert the expected directory entry so the timeout regression test stays fast and stable

This commit introduces a significant reorganization of the project structure to improve maintainability and clarity.
Key changes include:
- Adjusted the directory layout for a more logical module organization.
- Removed unused crate dependencies, reducing the overall project size and potentially speeding up build times.
- Updated import paths and configuration files to reflect the structural changes.
