Summary of new stuff:

commit f4f1ee8499621856b83e7628105317a95e2e8543
Author: Nikodemus Siivola <nikodemus at sb-studio.net>

    fix bug in signature generation url-encoding

      Amazon's docs say:

      "Do not URL encode any of the unreserved characters that RFC 3986
      defines. These unreserved characters are A-Z, a-z, 0-9, hyphen
      ( - ), underscore ( _ ), period ( . ), and tilde ( ~ )."

      Prior to this we also skipped encoding $!*'(), and didn't skip
      the tilde.

     I cannot help but think that we should map statuses to
     keywords instead.

    RUN-INSTANCES now returns a list if multiple instances were started

      Also accept :MINCOUNT and :MAXCOUNT as integers, in addition to string.

    first cut at the Amazon Elastic Load Balancing API

      * Use DEFACTION to speficy the API -- easier to add support
        for other API versions this way.

      * All actions in 2009-05-15 API implemented.

      * Responses as unparsed lists for now.

Subject: [cl-ec2-devel] AWS API design thoughts
Message-ID: <BANLkTi=qqorqXpHtWJ-AOghJWepdCeE-8A@mail.gmail.com>

Xach added ad-hoc to To: .. because I know he's been thinking about
some of this stuff too.

Having implemented one version of the load-balancing API with
clever-but-dirty macrology, I'm pretty sure that sooner or later the
rest should be reimplemented the same way -- otherwise it's hard to be
sure the API is actually properly implemented, and not just some wierd
subset.

I'm also thinking that this is the way to support multiple API versions.

(defclass 2010-01-01 (elb-api) ())

(with-api-version (2010-01-01)
  ...)

where user-level API functions call generic functions specialized on
the API class.

A major reworking will break compatibility pretty seriously, though,
so I suspect a if/when I get to that part I will make up a new project
(CL-AWS?) so that users don't have the carpet yanked from beneath
them...

Another thought I had is that credentials should really be
encapsulated in an object that doesn't print the secret key as part of
its PRINT-OBJECT method: otherwise it's far too easy to leak your keys
when pasting or posting a backtrace.

Just FYI, musing out loud, etc.
