ar_mailer 1.3.2

Eric Hodel | Wed, 29 Apr 2009 21:04:00 GMT

ar_mailer is a two-phase delivery agent for ActionMailer. Even delivering email to the local machine may take too long when you have to send hundreds of messages. ar_mailer allows you to store messages into the database for later delivery by a separate process, ar_sendmail.

Changes:

  • Terminate SMTP connection on TimeoutError since Net::SMTP may be in a bogus state. Issue by Eric O’Connell.
  • Don’t require Email class to exist. Bug #22843 by Joachim Glauche.
  • Switched to minitest
  • Upgraded to modern Hoe
  • Updated configuration information for Rails > 2.0

Binding#remove_local_variable

require 'rubygems'
require 'inline'

class Binding
  inline do |builder|
    builder.include '"node.h"'
    builder.include '"env.h"'

    ##
    # struct BLOCK isn't in any header, so include it here.

    builder.prefix <<-C

    ##
    # :method: remove_local_variable
    #
    # Removes the local variable +name+ and replaces it with nil.
    #
    # Ordinarily if a local variable didn't exist it would raise
    # NoMethodError, but currently after #remove_local_variable it doesn't, it
    # just returns nil.
    #
    # In order to make this behave correctly, block->body would need to be
    # walked, duping nodes (so as not to affect future invocations of this
    # method) and replacing the LVAR nodes with VCALL nodes.
    #
    # That's just too much work for 17:15, though.  Maybe tomorrow.

InfoQ on RubyGems Plugins

Eric Hodel | Thu, 23 Apr 2009 00:05:39 GMT

RubyGems 1.3.2 introduced a new feature: plugins that can hook into the install process and provide new commands. An example is Ryan Davis’ graph that visualizes dependencies between installed Gems. We talked to RubyGems maintainer Eric Hodel to learn more. By Mirko Stocker

quick_cert 2.0

Eric Hodel | Thu, 16 Apr 2009 08:41:00 GMT

quick_cert version 2.0 has been released!

seattlerb.rubyforge.org/quick_cert
rubyforge.org/projects/seattlerb

quick_cert allows you to quickly and easily create SSL certificates. It uses a simple configuration file to generate self-signed client and server certificates.

quick_cert (formerly QuickCert) was one of the first things I released for Ruby, some four years ago. I’ve heard over the years that (shockingly!) people have continued to use it. Here it is for the first time as a gem!

Changes:

  • 2 minor enhancements:
  • Released as a gem
  • Reorganized for Hoe
  • 3 discoveries:
  • CVS is odd after not using it for so long
  • My ruby style hasn’t changed much in the past five years
  • I still don’t know how OpenSSL works

RubyGems 1.3.2

Eric Hodel | Wed, 15 Apr 2009 21:48:00 GMT

NOTE: RubyGems 1.1 and 1.2 have problems upgrading when there is no rubygems-update installed. You will need to follow the second set of update instructions if you see “Nothing to update”.

Release 1.3.2 fixes some bugs and adds some features.

Select New Features:

  • RubyGems now loads plugins from rubygems_plugin.rb in installed gems. This can be used to add commands (See Gem::CommandManager) or add install/uninstall hooks (See Gem::Installer and Gem::Uninstaller).
  • Gem::Version now understands prerelease versions using letters. (eg. ‘1.2.1.b’) Thanks to Josh Susser, Alex Vollmer and Phil Hagelberg.
  • RubyGems now includes a Rake task for creating gems which replaces rake’s Rake::GemPackageTask. See Gem::PackageTask.
  • Gem::find_files now returns paths in $LOAD_PATH.
  • Added Gem::promote_load_path for use with Gem::find_files
  • Added Gem::bin_path to make finding executables easier. Patch #24114 by James Tucker.
  • Various improvements to build arguments for installing gems.
  • `gem contents` added --all and --no-prefix.
  • Gem::Specification
    • #validate strips directories and errors on not-files.
    • #description no longer removes newlines.
    • #name must be a String.
    • FIXME and TODO are no longer allowed in various fields.
    • Added support for a license attribute. Feature #11041 (partial).
    • Removed Gem::Specification::list, too much process growth. Bug #23668 by Steve Purcell.
  • `gem generate_index`
    • Can now generate an RSS feed.
    • Modern indicies can now be updated incrementally.
    • Legacy indicies can be updated separately from modern.

Select Bugs Fixed:

  • Better gem activation error message. Patch #23082.
  • Kernel methods are now private. Patch #20801 by James M. Lawrence.
  • Fixed various usability issues with `gem check`.
  • `gem update` now rescues InstallError and continues. Bug #19268 by Gabriel Wilkins.
  • Allow ‘https’, ‘file’ as a valid schemes for --source. Patch #22485.
  • `gem install`
    • Now removes existing path before installing. Bug #22837.
    • Uses Gem::bin_path in executable stubs to work around Kernel#load bug in 1.9.
    • Correctly handle build args (after --) via the API. Bug #23210.
  • --user-install
    • `gem install --no-user-install` now works. Patch #23573 by Alf Mikula.
    • `gem uninstall` can now uninstall from ~/.gem. Bug #23760 by Roger Pack.
  • setup.rb
    • Clarify RubyGems RDoc installation location. Bug #22656 by Gian Marco Gherardi.
    • Allow setup to run from read-only location. Patch #21862 by Luis Herrera.
    • Fixed overwriting ruby executable when BASERUBY was not set. Bug #24958 by Michael Soulier.
    • Ensure we’re in a RubyGems dir when installing.
    • Deal with extraneous quotation mark when autogenerating .bat file on MS Windows. Bug #22712.

Deprecation Notices:

  • Gem::manage_gems has been removed.
  • Time::today will be removed in RubyGems 1.4.

For a full list of changes to RubyGems and the contributor for each change, see the ChangeLog file.

Special thanks to Chad Wooley for backwards compatibility testing and Luis Lavena and Daniel Berger for continuing windows support.

How can I get RubyGems?

NOTE: If you have installed RubyGems using a package system you may want to install a new RubyGems through the same packaging system.

If you have a recent version of RubyGems (0.8.5 or later), then all you need to do is: 

  $ gem update --system   (you might need to be admin/root)

NOTE: RubyGems 1.1 and 1.2 have problems upgrading when there is no rubygems-update installed. You will need to follow the second set of update instructions if you see “Nothing to update”.

NOTE: You may have to run the command twice if you have any previosly installed rubygems-update gems.

If you have an older version of RubyGems installed, then you can still do it in two steps: 

  $ gem install rubygems-update  (again, might need to be admin/root)
  $ update_rubygems              (... here too)

If you don’t have any gems install, there is still the pre-gem approach to getting software … doing it manually:

  1. DOWNLOAD FROM: rubyforge.org/frs/?group_id=126
  2. UNPACK INTO A DIRECTORY AND CD THERE
  3. INSTALL WITH: ruby setup.rb (you may need admin/root privilege)

To File Bugs

The RubyGems bug tracker can be found on RubyForge at: rubyforge.org/tracker/?func=add&group_id=126&atid=575

When filing a bug, `gem env` output will be helpful in diagnosing the issue.

If you find a bug where RubyGems crashes, please provide debug output. You can do that with `gem --debug the_command`.

Thanks

Keep those gems coming!
