Adds an S3-API-level e2e regression net proving that a large-object GET on a
degraded EC set never returns a silently truncated body under a full
Content-Length -- the historical "unexpected EOF" bug fixed on main by
rustfs#4594 (short-body GetObject stream -> UnexpectedEof), rustfs#4560
(in-place per-part legacy degradation for the lazy multipart reader), and
rustfs#4585 (DARE package-boundary truncation detection). Those fixes each
ship a *unit* regression; this covers the layer they do not -- the full HTTP
GET path streaming a real body reconstructed from real on-disk EC shards.
New file crates/e2e_test/src/degraded_read_eof_regression_test.rs, single-node
4-disk (EC 2+2) DiskFaultHarness, three scenarios:
(a) one disk offline: a 6 MiB single object (>=2 EC stripes) and a 3x5 MiB
multipart object GET back byte-identical with the correct Content-Length.
(b) mid-stream bitrot within quorum: 2 of 4 shards corrupted mid-file on a
large multipart object still reconstructs the full, hash-matching body.
(c) beyond read quorum (the heart of the net): 3 of 4 shards corrupted
mid-file -- the read MUST fail cleanly (non-2xx or a mid-stream body
error), NEVER close with a truncated body under the full Content-Length.
The shared get_checked() helper panics on the forbidden outcome (a clean 2xx
whose collected body is shorter than the advertised Content-Length), so the
truncation bug can never be silently tolerated.
CI placement: these spawn a 4-disk server per test and are resource-heavy, so
they stay OUT of the fast PR e2e-smoke filter. A new e2e-reliability nextest
test-group (max-threads=1) serializes them (and the existing
reliability_disk_fault_test) across nextest's process boundary; ci-7's nightly
full-e2e run picks them up. Visible via `cargo nextest list -p e2e_test`.

Activate the 36 dormant replication e2e tests in
crates/e2e_test/src/replication_extension_test.rs (zero ran anywhere before).
Split via the ci-4 nextest profile mechanism, no hand-rolled cargo-test lane:
- PR smoke (profile.e2e-smoke, existing e2e-tests job): the 20 fast
bucket-replication tests (target-registration / replication-check / list /
remove / delete admin paths) that validate config synchronously and never
wait for async convergence. Each spawns its own single-node rustfs server(s)
on random ports with isolated temp dirs, so parallel-safe by construction
(serial_test's #[serial] is a no-op under nextest's process-per-test model;
no test-group needed).
- Nightly (profile.e2e-repl-nightly + .github/workflows/e2e-replication-nightly.yml):
the remaining 16 = 6 slow data-plane tests + 9 _real_dual_node + 1
_real_single_node. Defined as 'replication module MINUS the PR allowlist' so
new replication tests default to nightly and are never silently unrun.
The nightly workflow builds the binary once, installs awscurl so the STS
dual-node test runs (skips gracefully with a visible log line otherwise), and
routes scheduled failures through .github/actions/schedule-failure-issue
(ci-8). Explicit division of labor with ci-5 e2e-full: these run only here.
Counts (cargo nextest list): e2e-smoke 83 (63 + 20), e2e-repl-nightly 16.

ci: quarantine walk_dir stall-budget flake under the ci profile (rustfs#4690)
First application of the flake policy from docs/testing/README.md: the
test failed on a zero-Rust-diff PR (#4674, run 29099382470) — timing
windows in the stall-budget accounting stretch under CI load. retries=2
under profile.ci only; local default profile still never retries.
Tracked by rustfs#4690 (30-day fix-or-delete deadline).
ci: run e2e smoke subset via nextest e2e-smoke profile (backlog#1149 ci-4)
The e2e-tests job previously ran a single test (delete_marker_migration
_semantics) out of ~400 in the e2e_test crate. Define a nextest
profile.e2e-smoke whose default-filter selects 17 fast single-node
dependency-free modules (63 tests) and run it in the job, reusing the
downloaded debug binary. The profile is the single wiring mechanism for
e2e tests in CI; admission criteria live in crates/e2e_test/README.md,
and docs/testing/e2e-suite-inventory.md records authoritative per-module
counts from cargo nextest list.
test(ci): add strict nextest ci profile with quarantine + flake policy
Formalize the existing ecstore-serial-flaky mechanism into a strict CI gate
(ci-10, absorbs infra-15; backlog#1149).
- .config/nextest.toml: add [profile.ci] with global retries=0 (never mask a
new race's first occurrence), fail-fast=false, and JUnit output at
target/nextest/ci/junit.xml. Add a quarantine section where flaky tests get
retries=2 under the ci profile only; each entry links one OPEN issue. First
members are the two backlog#937 ecstore groups
(concurrent_resend_same_part_commits_one_generation and
store::bucket::tests::bucket_delete_*), which keep their existing
ecstore-serial-flaky test-group serialization. Local default profile still
never retries.
- .github/workflows/ci.yml: run the main test step with --profile ci and upload
the JUnit report (if: always(), 3-day retention, run-number in name). The
migration-proof step stays on the default profile to avoid clobbering the ci
JUnit artifact (its tests are not quarantined).
- docs/testing/README.md: new skeleton (owned by backlog#1153 infra-11) holding
the flake policy: discover -> open issue within 24h -> quarantine with issue
link -> fix or delete within 30 days. AGENTS.md points to it.
Refs: rustfs/backlog#1149, rustfs/backlog#937, rustfs/backlog#1155
Two ecstore test groups pass in isolation but flake under the full parallel
nextest suite, producing CI noise on every in-flight PR (backlog #937):
- store::bucket::tests::bucket_delete_* race make_bucket into
InsufficientWriteQuorum because they share global disk-registry/lock-client
state with other concurrently running tests.
- bucket_lifecycle_ops::tests::concurrent_resend_same_part_commits_one_generation
exceeds its already-maxed 60s lock-acquire deadline only when the suite
saturates disk I/O.
serial_test's #[serial] does not serialize these across nextest's per-test
process boundary. Add a nextest test-group (max-threads = 1) that matches both
groups so they run serialized, removing the load-induced flake. No test or
production code changes; long-term global-singleton isolation is tracked
separately.
