go-fuzz unknown revision

[ptrcvc]

I'm playing around with a fakenet using a digital ocean droplet. go version go1.16.15 linux/amd64

building results in an error as dvyukov/go-fuzz is replaced:

$ go build
go: github.com/dvyukov/[email protected] (replaced by github.com/guzenok/[email protected]): version "v0.0.0-20210103140116-f9104dfb626f" invalid: unknown revision f9104dfb626f

i personally fixed this by removing line 48 from go.mod:

replace github.com/dvyukov/go-fuzz => github.com/guzenok/go-fuzz v0.0.0-20210103140116-f9104dfb626f

then:

$ go mod download github.com/dvyukov/go-fuzz

I don't really know why /dvyukov/go-fuzz was replaced, looking at the version history of go.mod showed some revisions related to it but i couldnt find the reasoning as to why. Unexperienced with all of this, so forgive me

Unfortunately, origin github.com/dvyukov/go-fuzz can't build the fuzzing test program for go-opera:

$ go run github.com/dvyukov/go-fuzz/go-fuzz-build -o=./fuzzing/gossip-fuzz.zip ./gossip
failed to execute go build: exit status 1
/tmp/go-fuzz-build1233413096/goroot/src/crypto/elliptic/p256_asm.go:32:12: pattern p256_asm_table.bin: no matching files found

The fix is still not merged, so we replaced origin go-fuzz with fixed fork in go-opera go.mod.

That is why dvyukov/go-fuzz was replaced.

@ptrcvc , as for your trouble on digital ocean droplet, show me the full output of go env please.
Now I don't see any barrier to download github.com/guzenok/go-fuzz v0.0.0-20210103140116-f9104dfb626f revision:

• commit exists: guzenok/go-fuzz@f9104dfb626f ;
• bare test works fine:

$ go mod init example                                                                                                                                                       
go: creating new go.mod: module example
$ go get github.com/guzenok/[email protected]
go: added github.com/guzenok/go-fuzz v0.0.0-20210103140116-f9104dfb626f
$ go clean -modcache
$ go mod download

I'm getting the error when compiling in an empty container:

@AaronKutch , I got the same error and fixed it by ENV GOPROXY in the dockerfile:

FROM fedora:34
RUN dnf install -y git make gcc gcc-c++ which iproute iputils procps-ng vim-minimal tmux net-tools htop tar jq npm openssl-devel perl rust cargo golang

ADD https://github.com/Fantom-foundation/go-opera/archive/refs/tags/v1.1.0-rc.5.tar.gz /go-opera/
ENV GOPROXY="https://proxy.golang.org,direct"
RUN cd /go-opera && tar -xvf * && cd ./go-opera-1.1.0-rc.5 && make opera && mv ./build/opera /usr/bin/opera

Looking why default GOPROXY="direct" does not work.
