(sorry if I already sent this - groups UI being weird)
Hmm... I seem to get the same results on both machines:
Mac:
$ go list -f '{{.Name}} {{.Stale}}' std | grep true | head
$ go list -installsuffix nocgo -f '{{.Name}} {{.Stale}}' std | grep true |
head
tar true
zip true
bzip2 true
lzw true
zlib true
ring true
tls true
x509 true
sql true
driver true
Linux:
ianrose@iantest-1:~$ go list -f '{{.Name}} {{.Stale}}' std | grep true |
head
ianrose@iantest-1:~$ go list -installsuffix nocgo -f '{{.Name}} {{.Stale}}'
std | grep true | head
tar true
zip true
bufio true
bytes true
bzip2 true
flate true
gzip true
lzw true
zlib true
heap true
It's like the mac version somehow knows not to try to save pkg files for
std libs...
