Encoding error: Encoding::CompatibilityError, Encoding::UndefinedConversionError

[scauglog]

with ruby 2.2.1 and simplecov 0.9.2
When i run my test with all gem included in 'vendor/cache' (I use bundle package), I have some encoding error. See full trace bellow. The issue is related to filters because when I delete all my simplecov filters everything goes right. I use continuous integration with jenkins and this error make deployment stop.

I tried to convert the string in UTF-8 but it doesn't work. Finally I manage to bypass my problem by catching this exception (I modified lib/simplecov/default.rb:7) but I don't know how to write a test for it, or how to solve the encoding problem.

Do you know what the incompatible Encoding::CompatibilityError (UTF-8 regexp with ASCII-8BIT string) string is so we can test against it?

above your lib/simplecov/default.rb:7 patch (what did you change !(src.filename =~ /^#{Regexp.escape(SimpleCov.root)}/i) to, can you add

p [Encoding.default_external, Encoding.default_internal, Encoding.find('locale'), Encoding.find('filesystem'), __ENCODING__, src.filename.encoding, src.filename.valid_encoding?, SimpleCov.root.to_s.encoding, SimpleCov.root.to_s.valid_encoding?, Encoding.compatibile?(src.filename, SimpleCov.root), Encoding.compatibile?(src.filename.force_encoding(Encoding::BINARY), SimpleCov.root.to_s.force_encoding(Encoding::BINARY))]`

(it's possible there's typos in that.. I just wrote it up

@colszowka can you add a 'waiting for response' label?

force_encoding return an error :

force_encoding': can't modify frozen String (RuntimeError)

the wrong string are filename:

Oh, SimpleCov.root.to_s.dup.force_encoding(Encoding::BINARY)) missing the .dup

[PragTob]

Another encoding bug related thingy :(
