How to examine dependencies of previous gems

Ruby
1

Hi,

I am trying to see if there are any differences in the dependencies for
a specific gem between different releases.

For example:

sherwin-mac{198}% gem -v
1.3.4

sherwin-mac{199}% gem dep -r mongrel -v 1.1.5
Gem mongrel-1.1.5
gem_plugin (>= 0.2.3, runtime)
daemons (>= 1.0.3, runtime)
fastthread (>= 1.0.1, runtime)
cgi_multipart_eof_fix (>= 2.4, runtime)

sherwin-mac{200}% gem dep -r mongrel -v 1.1.4
No gems found matching mongrel (= 1.1.4)

Am I missing something simple?

tks, louie

Well, we certainly are! How about: gem list mongrel
Do you have mongrel 1.1.4 installed?

Hi Rob,

I don’t have 1.1.4 installed locally. In fact that is what I’m trying to
avoid. What I am hoping to do is look at the remote gems (-r) without
having to install each release on my system first.

tks, louie

Oh, that leads to an explanation, too. Does this help?

$ gem list -d mongrel

*** LOCAL GEMS ***

mongrel (1.1.5, 1.1.4, 1.1.3, 1.0.1)
Author: Zed A. Shaw
Rubyforge: http://rubyforge.org/projects/mongrel
Homepage: http://mongrel.rubyforge.org
Installed at (1.1.5): /Library/Ruby/Gems/1.8
(1.1.4): /Library/Ruby/Gems/1.8
(1.1.3): /Library/Ruby/Gems/1.8
(1.0.1): /System/Library/Frameworks/Ruby.framework/
Versions/1.8/usr/lib/ruby/gems/1.8

 A small fast HTTP library and server that runs Rails, Camping,

Nitro
and Iowa apps.

$ gem dep mongrel -v=1.1.4
Gem mongrel-1.1.4
gem_plugin (>= 0.2.3, runtime)
daemons (>= 1.0.3, runtime)
fastthread (>= 1.0.1, runtime)
cgi_multipart_eof_fix (>= 2.4, runtime)

So there doesn’t appear to be any difference in the dependencies
between 1.1.4 and 1.1.5.

Sorry I guess I was not clear that my question is about using gem
commands and not specifically about mongrel. I just used mongrel as an
example

I just noticed something the leads me to believe that this issue has to
do with the way the gem server is setup and not with the dependency
command. There is a new release or rails and the default query now shows
the last two releases. I can look a the dependencies for each of the
releases listed but not any previous release.

gem query -r -n ^rails$

*** REMOTE GEMS ***

rails (2.3.4, 2.3.3)

gem dep rails -r -v 2.3.3
Gem rails-2.3.3
rake (>= 0.8.3, runtime)
activesupport (= 2.3.3, runtime)
activerecord (= 2.3.3, runtime)
actionpack (= 2.3.3, runtime)
actionmailer (= 2.3.3, runtime)
activeresource (= 2.3.3, runtime)

sherwin-mac{226}% gem dep rails -r -v 2.2.2
No gems found matching rails (= 2.2.2)

tks, louie

0.9.0, 0.8.5, 0.8.0, 0.7.0, 0.6.5, 0.6.0)

You may be right. The older versions certainly do exist (2.2.2 in
particular), but must not be searched/found the same way.
