[ruby-core:97276] [Ruby master Bug#13675] Should Zlib::GzipReader#ungetc accept nil?

From: matz@...
Date: 2020-02-27 05:13:11 UTC
List: ruby-core #97276
Issue #13675 has been updated by matz (Yukihiro Matsumoto).


`IO#ungetc` should be fixed. The patch looks good to me.

Matz.


----------------------------------------
Bug #13675: Should Zlib::GzipReader#ungetc accept nil?
https://bugs.ruby-lang.org/issues/13675#change-84393

* Author: Eregon (Benoit Daloze)
* Status: Open
* Priority: Normal
* ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
IO#ungetc accepts nil and just does nothing:

    p File.new(__FILE__).ungetc(nil)

But on a GzipReader it fails:

    require 'zlib'
    zip = "\x1F\x8B\b\x00,\xDC\xD1G\x00\x0334261MLJNI\x05\x00\x9D\x05\x00$\n\x00\x00\x00"
    io = StringIO.new zip
    gz = Zlib::GzipReader.new(io)
    p gz.ungetc(nil)
    # =>
    repro.rb:8:in `ungetc': no implicit conversion of nil into String (TypeError)
        from repro.rb:8:in `<main>'

Should Zlib::GzipReader#ungetc accept nil?
Or should IO#ungetc also raise when given nil?
