The go pprof only shows the memory which is allocated by the go-runtime, so cgo allocations go un-noticed, which makes hard to debug cgo memeory leaks. This project aims to help developers to detect memory leaks in go program with c bindings.
cgoleak is a tool to detect memory leaks in Go applications with cgo
Usage:
cgoleak [flags]
Flags:
-h, --help help for cgoleak
--interval int interval to check for leaks (default 5)
--path string path to the binary
--pid int pid of the process
This program is a trimmed version of bcc's memleak.py to fulfill the needs of the go developer.
The memleak.py counts both runtime allocation and cgo allocation. It can only store a fixed
number of samples. So it drops cgo samples when it doesn't meet the sampling requirements.
This makes memleak.py unusable for go developers usecase.
On the flip side, cgoleak only tracks cgo allocations. This project aims to solve go developer needs rather than being a generic memory leak detector.
