refactor: extract libwaku cgo bridge into internal/ffi (#114)
* refactor: extract libwaku cgo bridge into internal/ffi

Move the C preamble, cgo shims, and callback plumbing from pkg/kernel/nwaku.go
into internal/ffi/libwaku.go, where #111 scaffolded them to live. The bridge
exposes Go-typed Waku* primitives (handle in, strings out) and owns the
handle->event-handler registry, so pkg/kernel is now pure Go: WakuNode keeps
its full API, logging, and error texts, and just calls ffi.

Behavior is unchanged. Dropped four C shims that had no Go callers
(cGoWakuContentTopic, cGoWakuPubsubTopic, cGoWakuDefaultPubsubTopic,
cGoWakuLightpushPublish). CGO flags still come from the environment
(Makefile/CI untouched).

Part of #106.

* refactor: move libwaku bridge into internal/ffi/libwaku subpackage

One subpackage per C library so a binary links exactly the libraries it
imports: libwaku and liblogosdelivery carry overlapping symbols and must never
link together (until logos-delivery#3851). With the package named libwaku the
Waku* prefixes became stutter, so the exported primitives drop them
(libwaku.New/Start/RelayPublish/...). internal/ffi keeps an umbrella doc.go
stating the rule.

logos-delivery Go Bindings

Go bindings for the Waku library.

Install

go get -u github.com/logos-messaging/logos-delivery-go-bindings

Building & Dependencies

libwaku (from logos-delivery) is required at compile-time.

Building with Makefile

If you have logos-delivery checked out, point the build to it:

# path to your existing logos-delivery clone
export LOGOS_DELIVERY_DIR=/absolute/path/to/logos-delivery
export CGO_CFLAGS="-I${LOGOS_DELIVERY_DIR}/library"
export CGO_LDFLAGS="-L${LOGOS_DELIVERY_DIR}/build -lwaku -Wl,-rpath,${LOGOS_DELIVERY_DIR}/build"

# compile all packages
make -C pkg/kernel build

# run all tests
make -C pkg/kernel test

# run a specific test
make -C pkg/kernel test TEST=TestConnectedPeersInfo

Development

When working on this repository itself, logos-delivery is included as a git submodule for convenience.

  • Initialize and update the submodule, then build libwaku
    git submodule update --init --recursive
    make -C pkg/kernel build-libwaku
    
  • Build the project. Submodule paths are used by default to find libwaku.
    make -C pkg/kernel build
