[ruby-core:96927] [Ruby master Bug#9790] Zlib::GzipReader only decompressed the first of concatenated files

Issue #9790 has been updated by Dan0042 (Daniel DeLorme).


I can't think of taking a random member but I can imagine wanting to extract to separate files.

```ruby
Zlib::GzipReader.each_file(filename).with_index do |gzip,i|
  File.open("output#{i}","w"){ |f| f.write(gzip.read) }
end
```

But I admit I haven't needed this personally, so maybe this is not so useful.

There is a similar old issue in Node that I came across that perfectly describes the situation in ruby:

https://github.com/joyent/node/issues/6032

In ruby given the following setup:

```
echo "1" > 1.txt
echo "2" > 2.txt
gzip 1.txt
gzip 2.txt
cat 1.txt.gz 2.txt.gz > 3.txt.gz
```

Calling:
    
```
Zlib::GzipReader.open("3.txt.gz") do |gz|
  print gz.read
end
```

would just print:

```
1
```
