gem generate_index で作成した gem server が gzip 圧縮を行う場合，Ruby 2.0 以上では gem のインストールに失敗します。

Ruby 1.9 では正常です。

サーバーを gzip 圧縮しない設定にすれば問題が解消します。

[ruby-dev:48016] [ruby-trunk - Bug #9562] [Assigned] Cannot install gems from gzip-compressing gem server

[naruse]

Issue #9562 has been updated by Yui NARUSE.

Status changed from Open to Assigned
Assignee set to Eric Hodel
Target version set to current: 2.2.0
Backport changed from 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN to 1.9.3: DONTNEED, 2.0.0: REQUIRED, 2.1: REQUIRED

You know, since Ruby 2.0.0, net/http automatically decode content-encoding;gzip.
Therefore Gem::Request, which uses Net::HTTP internally, also decode gz file, for example specs.4.8.gz,
if a gemsource server sets Content-Encoding: gzip to gz files.

Individual gem servers may hit this issue if people accidentally set Content-Encoding: gzip.
I think this issue should be avoided by RubyGems, and a patch may be following:

    diff --git a/lib/rubygems/request.rb b/lib/rubygems/request.rb
    index d2f076f..588dae4 100644
    --- a/lib/rubygems/request.rb

[ruby-dev:48022] [ruby-trunk - Bug #9562] [Rejected] Cannot install gems from gzip-compressing gem server

[drbrain]

Issue #9562 has been updated by Eric Hodel.

Status changed from Assigned to Rejected

If the server does not return a gzip Content-Type for a .gz file it is misconfigured. This is not a bug in rubygems.

[ruby-dev:48029] [ruby-trunk - Bug #9562] Cannot install gems from gzip-compressing gem server

[knu]

Issue #9562 has been updated by Akinori MUSHA.


Eric, I think the problem is that Gem::RemoteFetcher#fetch_path fails in `Gem.gunzip data` if the `data` is already decoded by Net::HTTP of Ruby 2.0 and later.
It happens when the HTTP server is configured to set a `Content-Encoding: gzip` header for .gz files, which itself is not necessarily a misconfiguration.
