* chore(ecstore): drop the bucket dead_code blanket
The last blanket of the backlog#1823 burn-down, and the largest: 71 items across lifecycle, replication, metadata, quota, object lock and bucket utils. Four are deleted.
Deleted, all trivial:
- check_valid_object_name and check_valid_object_name_prefix, a pair that only calls into each other with no external caller. Worth stating plainly so nobody reads this as a validation gap: object names are validated through check_object_name_for_length_and_slash, which is live; this pair is a second, unwired entry point.
- DEFAULT_HEALTH_CHECK_RELOAD_DURATION, a lone unused constant.
- The LifecycleReplicationConfig alias, which orphaned a re-export in replication/mod.rs that goes with it.
Everything else is kept, in four groups, because the blanket here was hiding structure rather than rot:
Windows platform gating. WINDOWS_RESERVED_NAMES, the two reason constants and object_name_has_windows_incompatible_segment are called from inside the #[cfg(target_os = "windows")] block in check_object_name_for_length_and_slash (utils.rs:228-255), so they only read as dead on non-Windows hosts. As with the Linux gating in the disk root, this cannot be adjudicated locally: cargo check for both x86_64-pc-windows-msvc and x86_64-unknown-linux-gnu fails in the aws-lc-sys build script for want of a cross C toolchain. CI covers both.
Declared boundary surface. The *_boundary.rs and *_bridge.rs files carry the replication split plan's contracts, which scripts/check_architecture_migration_rules.sh pins through the EcstoreReplicationBoundaryImports section of the split-plan doc. Their unused items are declarations, not leftovers.
test-util seams. ConfigWriteLockProbe with install/wait_until_attempted follows the same pattern as the barriers in the services and set_disk roots.
MinIO-parity tier/lifecycle entry points that this port never wired: apply_lifecycle_action, get_transitioned_object_reader, recover_tier_free_versions, delete_object_from_remote_tier, abort_tier_delete_journal_entry and the replication pool's worker-management surface. These are complete, substantial machinery with no caller — the same shape as data_usage's local_snapshot feature. Removing them is a product decision, so they are made explicit here rather than deleted.
Verification, four lanes warning-free: default, --tests, --features rio-v2 --tests, --features test-util --tests. cargo nextest run -p rustfs-ecstore 4096 passed; clippy --lib --tests -D warnings clean; make pre-commit exit 0. Note that clippy is what caught the orphaned re-export above: cargo check and pre-commit both treat unused_imports as a warning.
Ref rustfs/backlog#1823 (step 2, final root).
* chore(ecstore): correct inaccurate dead_code reasons in the bucket root
Six items were labelled 'asserted by this file's tests' or as MinIO-parity
entry points while having no caller at all - free get_bucket_acl_config and
created_at only reach their own live methods (production goes through
created_at_in), BucketVersioningSys::get_in, utils::serialize_content and
ServiceType have no reference anywhere, and with_transition_queue_env_async
is an unused test fixture, not a tier entry point. Name what each one is so
the next reader does not assume coverage that is not there.
Ref rustfs/backlog#1823.
#5804 added the on-disk segment budget to check_bucket_and_object_names, but PUT validates through check_put_object_args, which has its own checks and never calls it. An over-NAME_MAX key therefore still reached the disk layer and came back to the client as ENAMETOOLONG → InternalError 500, exactly the behavior #5785 reported.
Caught by re-running the acceptance suite against the locked build 4b2d79f5d, which contains #5804: S3-003 still failed with a 512-byte key.
Multipart is unaffected — check_new_multipart_args and check_multipart_object_args both route through check_object_args → check_bucket_and_object_names, which already carries the budget.
Verification: new test pins the same boundaries on check_put_object_args (255 ok / 256 rejected, byte-based via CJK, multi-segment long keys ok, __XLDIR__ budget for directory keys); cargo test -p rustfs-ecstore --lib -- bucket::utils 17 passed; cargo clippy -p rustfs-ecstore --all-targets clean; make pre-commit green.
fix(ecstore): reject over-NAME_MAX object key segments up front and classify irreconcilable parity as corrupt metadata
Two defects found during release acceptance and the backlog#1776 investigation:
Object keys with any path segment longer than 255 bytes could never be stored (each segment maps to one on-disk directory entry), but the failure surfaced only when the disk layer hit ENAMETOOLONG, which leaked to clients as InternalError 500 (rustfs#5785). Validate the on-disk segment budget in check_bucket_and_object_names so such keys fail deterministically as ObjectNameInvalid (4xx) before any I/O. Directory-object keys (trailing '/') account for the __XLDIR__ suffix their final segment carries on disk.
object_quorum_from_meta conflated two very different no-quorum situations (rustfs#5801): stray or foreign metadata whose parity values are garbage produced the same retryable-looking ErasureReadQuorum (503) as a genuine partial outage, so clients retried unrecoverable reads and monitoring could not tell corruption from capacity loss. Now (a) parity counts outside [0, total_shards] are treated as invalid entries instead of being clamped to i32::MAX, which could poison common_parity's occurrence counting, and (b) when a full read quorum of disks answers but their parity values cannot be reconciled, the error is FileCorrupt — heal-actionable and non-retryable — while too-few-healthy-replies keeps returning ErasureReadQuorum.
Verification: 4 new unit tests (segment budget boundaries incl. byte-vs-char and __XLDIR__ budget; garbage parity sanitization; corrupt-vs-quorum classification), metadata::tests + utils::tests 62/62, set_disk+bucket suites 1214 passed with the single pre-existing heal_queue_marks_missing_versioning_state_as_missed cross-test flake also failing on a clean tree (not introduced here), clippy clean, make pre-commit green.
fix(api): return descriptive InvalidArgument reason for Windows-unsupported object keys
On Windows hosts object keys containing NTFS-reserved characters or
Win32-unaddressable path segments are rejected up front, but the client
only saw a bare "Invalid argument" (issue #3299). Attach an explicit
reason to these rejections and surface non-empty InvalidArgument reasons
through the S3 error message.
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.
