[nathany]

two most recent stable versions + tip

it looks like there is a data race to fix

#150

[nathany]

Still seeing data races on Travis. Doh!

Specifically on macOS. The race on Linux is resolved.

[pattyshack]

the data race is in the bsd build; that uses kqueue instead of inotify. #177 will not help here

[nathany]

data races in all the places

will come back to that one. 💤

on macOS Sierra 10.12

❯ go test -race -test.count=10
PASS
ok      github.com/fsnotify/fsnotify    104.165s

fsnotify git/master  
❯ go16 test -race -test.count=10

... the later doesn't seem to be finishing anytime soon

❯ go16 test -race 
# testmain
fatal error: unexpected signal during runtime execution
...

But then Go 1.6 doesn't work on Sierra anyway. I wonder what version of macOS Travis is running? Might need a macOS VM just to test Go 1.6 locally. 😢

[nathany]

well this is embarrassing... 😊

updated for Go 1.8

[nathany]

also requested Go 1.8 for AppVeyor. appveyor/ci#1330

Currently Windows tests are using Go 1.7.1

[twpayne]

FWIW you can use 1.x to get the latest stable release of Go, and (for example) 1.7.x to get the latest version of 1.7. For example:

go:
  - 1.7.x
  - 1.x

@twpayne Thanks for the note. The only problem with using .x is we need to wait for Travis CI to update their aliases, but they are in place now. I will update.
