Log Message:
Update to 2.35.

- 2.35 | 2012-11-06

  - support for "make installcheck"

	This does "make check" at its core, so the same env vars apply.
	Obviously, you should do "make install" first for sane results.

  - ‘receive-response’ spec takes thunk for ‘custom’ handling

	This means that instead of using:

	(list 'custom (values P1 P2 P3 P4))

	to construct a ‘receive-response’ spec, you can use:

	(list 'custom (lambda () (values P1 P2 P3 P4)))

	In fact, this is now the preferred way, as support for using
	‘values’ directly is now deemed a misfeature and marked for
	eventual removal (see below).

  - tested against Guile 2.0.6

	There are some deprecation warnings, however.

  - MARKED FOR REMOVAL

    - 2013-05-15 support for values in ‘receive-response’ spec

	Out of an explicit ‘call-with-values’ context, Guile 2.x will
	silently discard all values but the first if the continuation
	expects one value only (the common case).

	(cons 0 (values 1 2)) => (0 . 1)

	Thus, the ‘receive-response’ spec constructed by:

	(list 'custom (values P1 P2 P3 P4))

	fails to preserve P2, P3, P4 (w/ Guile 2.x).  See above for
	thunk support, the future-proof way to specify ‘custom’ procs.

- 2.34 | 2012-03-29

  - bug fix: unbotch ‘upath->filename-proc’
  - bug fix: unbotch ‘log-http-response-proc’

	In Guile-WWW 2.33 (2012-02-29), these procs were changed to use
	(ice-9 optargs), but the change was botched.

  - bug fix: ‘(www http) http:post-form’ reserves ‘#\&’ \ 
and ‘#\=’

	That is, in the absense of upload specs, the urlencoding for the
	key names and values now also includes ampersand and equal sign,
	as those used to delimit pairs and separate key and value within
	a pair, respectively.

  - bug fix: ‘url-coding:encode’ outputs two hex digits for 0-15

	Previously, octets 0 through 15 were output as "%0" through
	"%f", respectively.  Now, they are "%00" through \ 
"%0f".

  - portability fix: big dishing loop handles #f ‘sockaddr:path’

	For Unix domain sockets, some Guile versions have ‘sockaddr:path’
	sometimes return the empty string, others ‘#f’.

  - ‘(www url) url:parse’ can handle IPv6 addresses

	Handling doesn't imply validation, however.  For example:
	(url:host (url:parse "http://fool@[::ffff:bogus.0.2.1]:42/foo"))
	=> "[::ffff:bogus.0.2.1]"

  - ‘(... answer) hqf<-upath’ more efficient

	The char-set computation has been moved to load-time.

  - ‘(... cookies) simple-parse-cookies’ takes optional arg SEP

	By default, tokens are ‘#\,’ (comma)-separated.  You can use SEP
	to specify another character, e.g., ‘#\;’ (semicolon).

  - new ‘(www cgi) cgi:init’ option: cookies-split-on-semicolon

	If the server provides the CGI script with a "Netscape style"
	(i.e., old and deprecated) set of cookies, you can use this
	option to split them.

  - ‘(www cgi) cgi:getenv’ recognizes some more "idiomatic" names

	The following keys now are recognized by ‘cgi:getenv’ (that is,
	they no longer signal "unrecognized key" error): ‘server-name’,
	‘server-software’, ‘server-protocol’, \ 
‘auth-type’, ‘http-accept’.
	Also, the manual now marks those keys that either are aliases,
	or return parts of the associated value, of these idiomatic names.

  - new (... parse-request) proc: receive-request

	This uses the same underlying machinery as ‘receive-response’
	from (www http), and thus sports the same features.

	Additionally, there is a new ‘request’ type with five accessor
	procs: request-{method,upath,protocol-version,headers,body} and
	the new predicate ‘request?’.

  - new (... log) proc: string<-sockaddr

	This formats AF_UNIX or AF_INET addresses (including port).

  - new (... answer) proc: compose-response

	This is a stripped down variant of ‘mouthpiece’.  It uses the
	same underlying machinery as ‘send-request’ from (www http) and
	thus sports the same features.

  - MARKED FOR REMOVAL

  - test suite expanded

	Previously, there was just one test.  Now, there are several,
	and they are in directory v/ (for "validation", "verification",
	"vouchsafed", and so on).

  - doc license upgraded to GNU FDL 1.3

  - maintenance uses Guile-BAUX 20120309.1509.1c4bb92

- 2.33 | 2012-02-29

  - distribution now .tar.xz

	If you have GNU tar, you can use "tar xf" and it will DTRT.
	If not, you can use "xz -dc TARBALL | tar xf -" to unpack.

  - configure no longer checks for some widely-available modules

	The modules ‘(ice-9 and-let-star)’, ‘(ice-9 rdelim)’ and
	‘(ice-9 regex)’ have been widely-available since Guile 1.4.x.

  - configure uses SNUGGLE for cross-Guile portability

	SNUGGLE is Free Software: <http://www.gnuvola.org/software/>.
	It provides ‘build-aux/snuggle.m4’, which is more amicable than
	the various ‘guile.m4’ in the wild.

  - dropped ‘(www server-utils answer) string<-header-components’

	This was pre-announced below in Guile-WWW 2.28 (2010-06-22).

  - changes to (www http)

    - bug fix: ‘http:request’ sends message body as-is

	This procedure used to erroneously send ‘CRLF’ after each string
	specified in BODY.  Now, it sends BODY only.

    - ‘http:status-ok?’ also accepts numeric arg

	E.g., ‘(http:status-ok? 200)’ and ‘(http:status-ok? \ 
"200")’
	both return ‘#t’.

    - ‘http:request’ also accepts a symbolic method

	Of course, a string is still acceptable.  Additionally, it is
	now an error if ‘method’ is neither string nor symbol.

    - new procs: ‘send-request’, ‘receive-response’

	These give (www http) a more asynchronous feel; it is now
	possible to implement pipelining, connection re-use, etc.
	Support for "chunked" transfer encoding and other HTTP 1.1 bits
	is built-in, although you can explicitly downgrade to 1.0 if you
	wish.

	Other features: (optional) caller-directed i/o to reduce data
	motion; support for ‘u8vector’ body (see example in the docs);
	support for custom body type; caller-specifiable header-name
	normalization; procedure names w/o "http:" prefix :-D.

    - message field types now documented

	The message object returned by ‘receive-response’ has a numeric
	status-code and header names normalized by the caller.

	In contrast, for backward compatability, the message object
	returned by ‘http:request’ has a string status-code and
	lower-case header names.

	(Header names are symbolic in any case.)

    - new fluid: protocol-version

	This affects how ‘http:request’ calls ‘send-request’ internally.
	It also impacts ‘http:get’, ‘http:head’, and \ 
‘http:post-form’,
	which call ‘http:request’.

	The default value is ‘(1 . 0)’, i.e., HTTP 1.0.  The idea is to
	support backward compatability out of the box, but allow users
	to experimentally do:

	  (set-fluid! protocol-version '(1 . 1))

	without having to modify their current code.  (New code
	should use ‘send-request’ and ‘receive-response’ directly.)
	This is a transitional feature of Guile-WWW 2.x; 3.x will
	drop ‘http:request’ (et al) along with the need for this
	fluid, entirely.

  - (www cgi) recognizes ‘application/x-www-form-urlencoded’ better

	Before, Content-Type recognition was over-constrained, failing
	to handle parameters (usually of the form "; charset=...").
	Things are now more relaxed.

  - documentation now explicitly UTF-8

	This has no immediate impact, but if you regenerate the .info,
	it may be possible that the makeinfo you use will generate nicer
	quotes, e.g., ‘foo’ instead of `foo'.  Time will tell.
