hanzoai/s3 was an AGPL-3.0 MinIO fork whose network-copyleft blocks embedding
and reselling as a managed service. Replace it wholesale with a fork of
SeaweedFS (github.com/seaweedfs/seaweedfs, Apache-2.0, Go) which ships a
built-in S3 gateway + Filer.
- License: AGPL-3.0 -> Apache-2.0 (upstream LICENSE kept verbatim, incl.
"Copyright 2025 Chris Lu"); NOTICE added crediting SeaweedFS. No AGPL/BUSL/
SSPL/GPL or enterprise ("ee") files remain.
- Module: go.mod path set to github.com/hanzoai/s3 with a self-replace
(replace github.com/seaweedfs/seaweedfs => ./) so the ~1800 internal Go files
keep their upstream import paths with zero churn. Internal identifiers and
import paths are intentionally NOT renamed.
- CLI rebrand: the binary is built as `s3` (was `weed`); root usage, per-command
help/usage/flag strings, shell autocomplete program name, and the product name
in CLI output now read "Hanzo S3" / `s3`. Users never see `weed`.
(e.g. `s3 server`, `s3 filer`, `s3 master`, `s3 volume`, `s3 s3`, `s3 mount`.)
- Build: `make` (or `go build -o s3 ./weed`) builds the `s3` binary green;
`cmd/weed-db` and `cmd/weed-sql` also build; `go vet ./weed/command/` clean.
- README/LLM.md rewritten for Hanzo S3; AGENTS.md/CLAUDE.md symlinks preserved.
- Dropped a 33MB prebuilt Mach-O `stress` binary upstream had committed; `.gitignore`
updated to ignore the `s3` build output.

// TestSetXAttrCopiesValueBuffer reproduces the bug from
|
|
// https://github.com/seaweedfs/seaweedfs/discussions/9275 where `cp -a`
|
|
// of a file with an extended attribute leaves the destination with a
|
|
// corrupted value. The root cause is that go-fuse hands SetXAttr a
|
|
// `data` slice that aliases the per-request input buffer; when the
|
|
// buffer is returned to the pool and reused for another FUSE request,
|
|
// any reference still held by entry.Extended sees garbage.
|
|
//
|
|
// The bug only manifested when the file was open during setxattr (the
|
|
// open-fh path defers persistence to flush). We simulate that by
|
|
// mutating the caller-supplied buffer after SetXAttr returns.
