sdsCall stored &wg (a pointer to a stack sync.WaitGroup) in C memory (SdsResp.ffiWg) and the result callback dereferenced it from the nim-ffi thread while the caller was parked in wg.Wait(). That violates the cgo pointer rules: the GC can relocate the parked goroutine's stack, leaving the C-held pointer dangling, which corrupts memory under GC pressure. Pass the WaitGroup as a runtime/cgo.Handle (a stable uintptr token) instead, and resolve it back to *sync.WaitGroup in the callback. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
SDS Go Bindings
This repository provides Go bindings for the SDS library, enabling seamless integration with Go projects.
Installation
To build the required dependencies for this module, the make command needs to be executed. If you are integrating this module into another project via go get, ensure that you navigate to the sds-go-bindings/sds directory and run make.
Steps to Install
Follow these steps to install and set up the module:
- Retrieve the module using
go get:go get -u github.com/waku-org/sds-go-bindings - Navigate to the module's directory:
cd $(go list -m -f '{{.Dir}}' github.com/waku-org/sds-go-bindings) - Prepare third_party directory which will clone
nim-sdssudo mkdir third_party sudo chown $USER third_party - Build the dependencies:
make -C sds
Now the module is ready for use in your project.
Note
In order to easily build the libsds library on demand, it is recommended to add the following target in your project's Makefile:
LIBSDS_DEP_PATH=$(shell go list -m -f '{{.Dir}}' github.com/waku-org/sds-go-bindings)
buildlib:
cd $(LIBSDS_DEP_PATH) &&\
sudo mkdir -p third_party &&\
sudo chown $(USER) third_party &&\
make -C sds
