In an attempt to build the OpenJDK tools with icepick, I'm getting an
error when downloading the icepick tarball:

Indeed. The HTTP headers here look like this:
--8<---------------cut here---------------start------------->8---
Date: Fri, 26 Dec 2014 22:10:49 GMT
Server: Apache/2.2.22 (Debian)
ETag: 1200667312.0
--8<---------------cut here---------------end--------------->8---
For details, this can be reproduced like this:
--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use(web client)
scheme@(guile-user)> (http-get "http://icedtea.wildebeest.org/hg/icepick/archive/15425b469aea.tar.gz")
web/http.scm:854:12: In procedure parse-entity-tag:
web/http.scm:854:12: Bad qstring header component: 1200667312.0
Entering a new prompt. Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]> ,bt
In web/client.scm:
228:8 4 (request "http://icedtea.wildebeest.org/hg/icepick/archive/15425b469aea.tar.gz" #:body #f #:port #<input-output: s…> …)
In web/response.scm:
199:6 3 (read-response #<input-output: socket 13>)
In web/http.scm:
218:33 2 (lp ((server . "Apache/2.2.22 (Debian)") (date . #<date nanosecond: 0 second: 3 minute: 14 hour: 22 day: 26 mont…>)))
188:11 1 (read-header #<input-output: socket 13>)
854:12 0 (parse-entity-tag "1200667312.0")
--8<---------------cut here---------------end--------------->8---
And indeed, Section 14.19 of
<http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html> says that the
‘ETag’ header has type ‘entity-tag’.
‘parse-entity-tag’ is written like this:
--8<---------------cut here---------------start------------->8---
(define (parse-entity-tag val)
(if (string-prefix? "W/" val)
(cons (parse-qstring val 2) #f)
(cons (parse-qstring val) #t)))
--8<---------------cut here---------------end--------------->8---
Section 3.11 at <http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html>
confirms the above definition for ‘entity-tag’.
Lastly, ‘quoted-string’ in
<http://www.w3.org/Protocols/rfc2616/rfc2616-sec2.html> is defined as a
string surrounded by double quotes, basically.
So, in short, I think Apache httpd is returning an invalid ETag header,
and Guile’s HTTP client is right in rejecting it.
Having said that doesn’t help much though. I’m not sure how frequent
this is, and whether/how this could be worked around. Ideas?
Thanks,
Ludo’.

I've encountered the same issue while attempting to upgrade the
python-pillow package. For the newer versions 2.6.2 and 2.7.0, the
following errors are reported when downloading the source::
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

`/gnu/store/i40q1mk9dnkg2mfyvfhjyq8lcywmgvh1-Pillow-2.7.0.tar.gz' from

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I don't have any ideas on how to work around this issue in general. In
this case, we might be able to fetch the source from github rather than
pypi. But this should add to the question of how frequent this problem
is.

FWIW, pypi.python.org has been fixed after reporting the issue to the
webmasters.
Would it be desirable for the HTTP client to be a little more tolerant
in general?
