I. Google Wire for dependency injection

  • only one method: wire.Build(struct1.New, struct2.New) normally, struct1 will be dependency of struct2 if struct2.New only required a field in struct1 -> use FieldsOf() after new struct1 if struct2’s input is an interface, we need to bind that interface to a struct just created in struct1.New

II. Spcli proto

  • spcli proto gen
  • spcli proto publish [–force] topic_name path/file_name.proto

III. Go confusing stuff

  1. Empty list is not a nil
  2. var a *A // a := &A{} // &{ empty value each fields}

Draft

orders Item: .Stock .ItemType .PffInputPriceForced .SumStock .BundleDealInfo .ItemFulfillmentList

haveMultiWh

-> skip pre-check item stock for deducted items

IV. Go test

  • go test package.go package_test.go -v -cover
  • or move into package’s directory
  • go test -cover -v coverage: go test -coveprofile=prof.out visualization: go tool cover -html=prof.out

V. SPEX stuff

export SP_UNIX_SOCKET=/tmp/spex.sock socat -d -d -d UNIX-LISTEN:/tmp/spex.sock,reuseaddr,fork TCP:agent-tcp.spex.test.shopee.io:9299 list out all env variables: env ? SPEX self call

  1. spex server: all about SPEX agen sps.Init() sps.registerProcessor() sps.Register()
  2. spex client sps.Init() sps.subscribeConfig() sps.Register()
