This repository contains the versions of Consul source files that I'm interested in and the notes I made for learning purpose. Therefore, the code in this repository belongs to the original authors of Consul and should be used under the same license. See their license.
Each version is in its own sub-folder. My notes are all marked with NOTE(ywen). The log messages I added are prefixed with [ywen].
1.16.1was created from the tagv1.16.1.
I ran into the following build issues when I built Consul from source the first time:
1). go get . couldn't find net/netip (and another package that I don't remember) in GOROOT. This should be because I was using an older version of Go which didn't have net/netip as a built-in package. I fixed it by upgrading to the latest version of Go.
2). This line CGO_ENABLED=0 go install -ldflags "$(GOLDFLAGS)" -tags "$(GOTAGS)" in GNUmakefile reported error that suggested I was using invalid link options. The root cause was the variable $(GOLDFLAGS) was expanded to the following block:
gpg: Signature made Sat 09 Sep 2023 04:53:58 PM UTC
gpg: using RSA key FD606F0CE398E74E35CD69D40FC0A64AA26EEEF4
gpg: Can't check signature: No public key

This was because the git_date shell function in build-support/functions/10-util.sh shows the signature but I don't have the Consul developers' SSH public keys. I modified the git show command that git_date calls and passed --no-show-signature to fix this issue.
