* test: consolidate port allocation into shared test/testutil package
Move duplicated port allocation logic from 15+ test files into a single
shared package at test/testutil/. This fixes a port collision bug where
independently allocated ports could overlap via the gRPC offset
(port+10000), causing weed mini to reject the configuration.
The shared package provides:
- AllocatePorts: atomic allocation of N unique ports
- AllocateMiniPorts/MustFreeMiniPorts: gRPC-offset-aware allocation
that prevents port A+10000 == port B collisions
- WaitForPort, WaitForService, FindBindIP, WriteIAMConfig, HasDocker
* test: address review feedback and fix FUSE build
- Revert fuse_integration change: it has its own go.mod and cannot
import the shared testutil package
- AllocateMiniPorts: hold all listeners open until the entire batch is
allocated, preventing race conditions where other processes steal ports
- HasDocker: add 5s context timeout to avoid hanging on stalled Docker
- WaitForService: only treat 2xx HTTP status codes as ready
* test: use global rand in AllocateMiniPorts for better seeding
Go 1.20+ auto-seeds the global rand generator. Using it avoids
identical sequences when multiple tests call at the same nanosecond.
* test: revert WaitForService status code check
S3 endpoints return non-2xx (e.g. 403) on bare GET requests, so
requiring 2xx caused the S3 integration test to time out. Any HTTP
response is sufficient proof that the service is running.
* test: fix gofmt formatting in s3tables test files
Two bugs prevented reliable volume balancing when a Rust volume server
is the copy target:
1. find_last_append_at_ns returned None for delete tombstones (Size==0
in dat header), falling back to file mtime truncated to seconds.
This caused the tail step to re-send needles from the last sub-second
window. Fix: change `needle_size <= 0` to `< 0` since Size==0 delete
needles still have a valid timestamp in their tail.
2. VolumeTailReceiver called read_body_v2 on delete needles, which have
no DataSize/Data/flags — only checksum+timestamp+padding after the
header. Fix: skip read_body_v2 when size == 0, reject negative sizes.
Also:
- Unify gRPC server bind: use TcpListener::bind before spawn for both
TLS and non-TLS paths, propagating bind errors at startup.
- Add mixed Go+Rust cluster test harness and integration tests covering
VolumeCopy in both directions, copy with deletes, and full balance
move with tail tombstone propagation and source deletion.
- Make FindOrBuildRustBinary configurable for default vs no-default
features (4-byte vs 5-byte offsets).
