Congratulations on the Beta 2 release, pretty excited to test it out. Lots
of interesting updates!
I did notice one thing when I was playing around with Beta 1 and now Beta 2
that I wanted to ask about. Is it expected that binary size would increase
in this release? A toy example that has been somewhat of a benchmark in
previous releases is the simple hello world program:
package main
import (
"fmt"
)
func main() {
fmt.Println("Hello world!")
}
It seems like this program, when compiled with options to strip debugging
information has grown about 20% in size when compiled natively for macOS:
go version go1.8.3 darwin/amd64
$ go build -ldflags="-w -s"
$ ls -l
total 2320
-rw-r--r-- 1 Parker staff 79 Jun 16 18:47 main.go
-rwxr-xr-x 1 Parker staff 1181728 Jun 29 07:24 test
go version devel +eab99a8 Mon Jun 26 21:12:22 2017 +0000 darwin/amd64
$ go build -ldflags="-w -s"
$ ls -l
total 2792
-rw-r--r-- 1 Parker staff 79 Jun 16 18:47 main.go
-rwxr-xr-x 1 Parker staff 1424992 Jun 29 07:11 test
Anyone have any insight on whether this is expected and if a similar
increase should be expected across the board in this release?
Thanks,
Parker
