@haines You may be right. Do you want to look into it? It may just be some missing logic in our ported GzipReader#gets implementation. I suppose the test passed before because it fell back on io#ungetc which didn't actually unget anything, so the subsequent gets worked properly. Thanks for your help! I have some review comments I'll add. |

We generally don't collapse imports unless there's >20 or something.

If these don't exist in either MRI's suite or ruby/spec, it would be nice to add them there. We usually just put JRuby-specific stuff in test/jruby.

Makes sense. There are placeholders for these methods in ruby/spec, so I'll add them there.
Should I submit them to ruby/spec first and then pull them in once merged upstream?

You can submit them to our spec/ruby subdir. We merge both ways.

Make it a separate commit for sure though...makes it easier to merge. 😄

I've added the specs, which caught a bug in my implementation (I forgot to decrement

Looks good now...I'll merge! |
The test suite requires jruby/jruby#4636
Either follow what MRI does, or raise a bug, but please not spec different behavior without a bug report. |

I've had a stab at implementing the
unget*methods forZlib::GzipReader. The implementation is a bit limited in that the maximum number of bytes that can be "ungot" is hardcoded, since I'm using aPushbackInputStream. Also, it doesn't attempt to do anything clever with encoding (although I don't see that as a problem becausegetcdoesn't either).Let me know what you think!
Closes #4631
