Tweak POST to use pure POST api

[staticfloat]

Instead of multipart nonsense, use the undocumented form-data POST API (I got the idea from this guy)

Note that I haven't tested this, since I'm not sure how to run this Coverage.jl thing, but in a REPL session, the following returned me something:

julia> data
{"source_files"=>[{"coverage"=>{nothing,1,nothing},"name"=>"example.rb","source"=>"def four\
n  4\nend"},{"coverage"=>{nothing,1,0,nothing},"name"=>"lib/two.rb","source"=>"def seven\n  
eight\n  nine\nend"}],"repo_token"=>"NnS70s2bP8Wwvxquax6rdRz4zDnEwW5OK"}

julia> r = Requests.post(URI("https://coveralls.io/api/v1/jobs"), data = {"json" => json(dat
a)}, headers={"Content-Type" => "text/form-data"})
<snip a bunch of deprecation warnings>
Response(200 OK, 20 Headers, 66 Bytes in Body)

julia> r.data
"{\"message\":\"Job #3.1\",\"url\":\"https://coveralls.io/jobs/1754807\"}\r\n"

We can see what the Travis output says, and hope for the best!

{"message":"Job #10.1","url":"https://coveralls.io/jobs/1754899"}
Looking VERY promising

Hah wonderfull!

[IainNZ]

💯 very grateful!

[staticfloat]

Ah, didn't realize you'd already set it up to run alongside travis. Very neat!

[IainNZ]

I'm gonna polish it on https://github.com/IainNZ/RationalSimplex.jl (as a test case) then I'm hoping its something people will be able to drop as an extra line in their travis, e.g.

- julia -e 'Pkg.add("Coverage"); using Coverage; report_coveralls("PkgName")'

Sounds good to me! Neat tools like this make me happy. :)

I tried this out: https://coveralls.io/r/loladiro/SIUnits.jl. So how does it work? Does it only consider functions that are actually called?

[IainNZ]

Yeah if you look at the .cov files, for each line they either have a - or a number. - just means no count is possible (e.g. multiline statements, function declarations, comments), and the number will be 0 if the line is countable but never hit.
All I'm doing is taking the files, taking the .cov files, and converting them to the Coveralls format, which is the same: uncallable/untrackable lines are "null", everything else gets a count.

So it looks like you are missing 3 lines:
https://coveralls.io/files/193437379

When I ran this on JuMP.jl almost all the lines not called where error lines/early breakouts that weren't tested.

[Keno]

But there is also big functions like https://coveralls.io/files/193437379#L377, which don't show up as not covered.

Also reported here: JuliaLang/julia#5423 seems to be an issue with the tool
