Where is Libwww maintained today

[Kristian Spangsege-2]

Hi

According to http://www.w3.org/Library/ the latest version of Libwww
is 5.4.1, however the version on my FedorCore 6 is 5.4.1. This leads
me to suspect that Libwww is maintained elsewhere these days. Is that
correct?

The reson I'm asking is that I found a bug, and wanted to see if it
was fixed in the latest release (or maybe in CVS.)

Please advise as to where I can inspect the latest version and
potentially report a bug.

In case that tourns out negatively, I'll report it right here and right now:

In HTNet.c is the following definition of HTNet_addAfter:

PUBLIC BOOL HTNet_addAfter (HTNetAfter * after, const char * tmplate,
                           void * param, int status, HTFilterOrder order)
{
   if (!HTAfter) HTAfter = HTList_new();
   else HTNet_deleteAfter(after); /* Ensure not listed twice */
   return HTNetCall_addAfter(HTAfter, after, tmplate, param, status, order);
}

It is apparent that that same filter cannot be added twice, but this
is in conflict with the implementation of HTAfterInit in HTInit.c.
Here 'HTRedirectFilter' is added for multiple status codes. The rult
is that the redirection handler only workds for satatus TEMP_REDIRECT,
which obviously is not the intended behaviour:

PUBLIC void HTAfterInit (void)
{
   HTNet_addAfter(HTAuthFilter,        "http://*",        NULL,
HT_NO_ACCESS,         HT_FILTER_MIDDLE);
   HTNet_addAfter(HTAuthFilter,        "http://*",        NULL,
HT_REAUTH,         HT_FILTER_MIDDLE);
   HTNet_addAfter(HTPEP_afterFilter,   "http://*",        NULL,
HT_ALL,                 HT_FILTER_MIDDLE);
   HTNet_addAfter(HTRedirectFilter,    "http://*",        NULL,
HT_PERM_REDIRECT, HT_FILTER_MIDDLE);
   HTNet_addAfter(HTRedirectFilter,    "http://*",        NULL,
HT_FOUND,         HT_FILTER_MIDDLE);
   HTNet_addAfter(HTRedirectFilter,    "http://*",        NULL,
HT_SEE_OTHER,        HT_FILTER_MIDDLE);
   HTNet_addAfter(HTRedirectFilter,    "http://*",        NULL,
HT_TEMP_REDIRECT, HT_FILTER_MIDDLE);
   HTNet_addAfter(HTAuthInfoFilter,    "http://*",        NULL,
HT_ALL,                 HT_FILTER_MIDDLE);
   HTNet_addAfter(HTUseProxyFilter,    "http://*",        NULL,
HT_USE_PROXY,         HT_FILTER_MIDDLE);
   HTNet_addAfter(HTInfoFilter,        NULL,                NULL,
HT_ALL,                HT_FILTER_LATE);
}


Kind regards,

Minor correction: According to http://www.w3.org/Library/ the latest
version of Libwww is 5.4.0 (not 5.4.1).

Yes, the library will show 5.4.1 if you check out and build as per,

   http://www.w3.org/Library/cvs.html

This will include the updates and authors as listed in the change
log[1].  The packaging and build is particularly well done by Andreas
Bierfert for fedora  6 extras [2].

Okay, I will try to check it both places,  (just grabbed a copy of the
SRPMS for FC6).

What is the simplest test case that exhibits the unintended behavior ?

[2] Fedora Core 6, Extras, source package for w3c-libwww

http://download.fedora.redhat.com/pub/fedora/linux/extras/6/SRPMS/repoview/w3c-libwww.html

[Kristian Spangsege-2]

Hi again


So http://www.w3.org/Library/ really is the home of the latest version
of Libwww. In that case I think the website should be updated.
Whereever it says something about the latest release, it says 5.4.0:

http://www.w3.org/Library/#News
http://www.w3.org/Library/User/ReleaseNotes.html


About the bug:

The bug seems to remain in the latest CVS version.

A very simple test case for me is to use w3c command line utility and
request 'http://www.google.com'. This fails because for some reason
Google decides to redirect to "www.google.dk" (Denmark is where I
live.) It responds with status=302 (Found) and a 'Location' header.
This is supposed to make W3C follow the redirect, but it does not.

The fact that it is supposed to follow, is apparent from the
implementation of HTAfterInit (listed in my original mail.)

The fact that it does not work, is apparent from the lack of output
and inspection of 'w3chttp.out' and in fact is also apparent from
inspecting the source I listed in my first post.


I know this test case may be unavailable to you, but maybe you know of
another site that does a similar thing, or whatever. Anyway tell me if
you want me to also produce a minimal source code test program. The
bug, however, should be entirely obvious by inspecting only the source
I listed in my original post.


Regards,
Kristian Spangsege
