fix for Go 1.10 #34

wadey · 2018-02-20T15:56:48Z

Fixes #33 and #31.

A couple of fixes so that fsevents builds in Go 1.10. Sadly this breaks
compatibility with Go 1.9 and below, but there doesn't seem to be any
way to avoid that. I have not fully vetted it, just confirmed that it builds and the example runs.

the kFSEventStreamEventIdSinceNow type is now correctly unsigned, so
the the need to convert from a signed integer is no longer needed.
nil must be changed to 0 in a few places now.
We must cast to the correct C type in a few places.

we could perhaps use the flag go1.10 changing a little the file organization (in order not to break the backwards compatibility? I volunteer to do that)

wadey · 2018-02-20T16:23:39Z

For a quick fix could just make a complete copy of the old wrap.go and put it behind the build flag and not waste time on reorganization

nilleb · 2018-02-20T16:51:56Z

mh, no, unfortunately it won't work. unless we don't modify the before_script part of the job
(in fact, the go1.9 means from go 1.9 onward, thus will be always compiling this file -- creating conflicts with the 1.10 one)

There were backwards incompatible changes to cgo in Go 1.10: - https://golang.org/doc/go1.10#cgo

wadey · 2018-02-20T19:33:11Z

I pushed a change that should build for all versions of Go, the travis build passed for latest Xcode:

https://travis-ci.org/fsnotify/fsevents/jobs/343973059

It failed for the oldest version of Xcode though, for what seems like an unrelated issue. I'm testing building with multiple versions of Go now.

Test with Go 1.8, 1.9, 1.10 and latest stable (in case we forget to update this later). sw_vers is only present on the osx_image builds so make the output for it conditional.

Ok, I've pushed some changes to the Travis config so that it tests with Go 1.8, 1.9 and 1.10. All builds pass: https://travis-ci.org/fsnotify/fsevents/builds/344036544

nilleb · 2018-02-21T08:31:59Z

I hope this patch will be merged soon! :-)

drewwells · 2018-02-23T05:09:48Z

wrap_go1.9 probably would have been sufficient :D

drewwells · 2018-02-23T05:12:51Z

Testing this in my project, tests look good. We're losing some coverage b/c of the duplication of code

drewwells · 2018-02-23T05:37:17Z

great work, thank you for your contribution 🎉 🎉 🎉
