[Dillo-dev]GTK FLTK and other Render

by shuishuila

Hi, dillo-dev， I want to port dillo to set-top box as menu(OSD). But it don't have X11,GTK. How many work need to do if I have to write widget myself? I think it's a pity that dillo combine tightly with glib/gtk, so it is hard to port to X,FrameBuffer,DirectFB etc. If dillo have it's own widget and event handle, it is a excellent broswer for embedded system.

Hi, Sorry, I just realized that a "pre" tarball is required to test the socklen_t detection (else it depends on the local machine's installed auto* tools). I'm preparing it, stay tuned. Cheers Jorge.-

[Dillo-dev]Test for socklen_t in configure.in

by Jorge Arellano Cid

Hi there, Our configure.in is in need of a test for socklen_t. I thought this one could be a good one: dnl ------------------- dnl Check for socklen_t dnl ------------------- dnl AC_MSG_CHECKING(for socklen_t) AC_TRY_COMPILE([#include <sys/types.h> #include <sys/socket.h> socklen_t x; ], [], [AC_MSG_RESULT(yes)], [ AC_TRY_COMPILE([#include <sys/types.h> #include <sys/socket.h> int accept(int, struct sockaddr *, size_t *); ], [], [ AC_MSG_RESULT(size_t) AC_DEFINE(socklen_t, size_t)], [ AC_MSG_RESULT(int) AC_DEFINE(socklen_t, int)])]) but my autoheader complains... Can someone please complete the patch, I'm currently chasing a segfault bug I found... TIA Jorge.-

Well, they know the bad HTML issue and made a tables version for the directory listing (that was also faulty but that as of the bug entry should be corrected now). > > http://nagoya.apache.org/bugzilla/show_bug.cgi?id=10880 suggests that > the default won't change in the 2.0 series, <q from above URL> Item 1 has been fixed in 2.1 and is proposed for backport. Item 2 ... ehm? what standard? html? agreed. ;-) As said you can use IndexOptions to fix that issues. For backwards compat we should stick with the current defaults. Item 3 doesn't appear in the current tree so I'm assuming it fixed already. </q> The backwards compatibility is a point that was easy to foresee. Although the developer above doesn't seem to be much concerned about the standards, and this surprises me. A simple solution woud be to replace: -<HR> +</PRE><HR><PRE> and replece the <IMG> tag with its alt text, and make _that_ the default in apache. They could provide an option to produce the old directory listing, and thus, leave the responsibility of deciding whether to serve bad HTML to every webmaster, but the default should be valid HTML (IMHO). In brief, the webmaster would have: - Good HTML by default (no images) based on <PRE> - The option to serve bad HTML with images based on <PRE> - The option to serve good HTML with images based on <TABLE> > > > After analizing the produced HTML for directory listings, I > > found that isolating the <HR> outside <PRE> is a trivial fix that > > helps keeping the block element outside. > > > > That is: > > > > - <HR> > > + </PRE><HR><PRE> > > > > Very simple.

I got a bit discouraged to make the patch and submit it because it's a toilsome work that I don't know will have a warm reception ;) If you feel like doing it, please go ahead, but I'd suggest first to contact one of the developers and explain the idea before making a patch. It's reasonable, unless they have to support some scripts that rely on the directory listing source being served exactly the old way... > > Their most recent attempt not to lose patches seems to be described in > http://marc.theaimsgroup.com/?l=apache-httpd-dev&m=108012889313136&w=2 > which suggests that bugzilla may be being watched closely. This is good news. But the whole issue is more a "backwards compatibilty" problem than "valid HTML".

Yes Francis, I think the same as you, but I'd appreciate if someone asks them if serving good HTML without the images for the directory listing is a good default (providing the alternatives described above). For those that read this far: the CVS contains the patch I made for this issue. Cheers Jorge.-

Seeing all these webservers serve up the html incorrectly, do you make them correct the issue or do you have Dillo also 'render incorrectly'? I know there are a lot of sites that are not rendered correctly with Dillo. Whether these issues would be the reason or not I am not educated enough to know.

It then will not render well with Dillo either. The fact is that the html is invalid, and therefore renders funny. Saving the html and serving it from another web server, or fetching it from a file, won't change that it is invalid. The reason it is an apache problem is that the html is generated by apache, not that it is served by apache. > I sense I am still missing part of this discussion but thought I would > add my 2 cents anyways. *;o) Does that fill in the missing bit? As it happens, thttpd (2.25b) has a very similar problem, in that its default directory listing, if enabled, looks like === <H2>Index of /</H2> <PRE> mode links bytes last-changed name <HR>dr-x 2 4096 Mar 23 12:23 <A HREF="/./">.</A>/ === which current dillo will also recognise as invalid, and render not as the server author presumably hoped.

What I think I am reading is that this is an Apache issue as far as why the page isnt rendering well. I am running Thttp for a server. I copied the source and stuck it on my server.
