css :visited and security
by corvid＠lavabit.com 05 Apr '10

05 Apr '10

The other day, I saw another of those pages about using :visited and display in order to allow others to learn whether the user has visited a page. (I remember Johannes pointing to a page about this last year, too.) I wonder whether it would be sensible to have a dillorc option defaulting to NO for whether to use :visited.

Starting dpis on FreeBSD: blackhole(4) timeouts
by bf2006a＠yahoo.com 09 Feb '10

09 Feb '10

I'm using dillo on FreeBSD 9-CURRENT, and ever since the dpi framework was converted to use Internet domain sockets, I've been plagued by long delays when starting dpis because I'm using blackhole(4) by setting net.inet.tcp.blackhole to be nonzero. An example of the problem: Nav_open_url: new url='dpi:/bm/' Dpi_check_dpid_ids: Operation timed out [dpid]: a_Misc_mksecret: e1ab7e05 Dpi_blocking_start_dpid: try 1 dpid started where truss -faedD -s

some added measure of security? Regards, b.

dpidc

- Why does install-dpi-local put dpidc in ~/.dillo, anyway? Wouldn't that be unusual for it to be in anyone's path? - Do you think it would be silly to make a little manpage for dpidc? - I'm contemplating making dpidc's exit values distinguish between the cases of: 1) Bad usage. Wrong number of args. 2) I can't find the stuff to communicate with dpid (either because this the first use of dillo, or the dpi system has been changed). 3) Connection refused. I think dpid just isn't running right now. 4) Something is breaking while communicating with dpid.

display: inline

I am currently working on adding CSS support for "display: inline" tags. They are commonly used for navigation menus. As these menus are nothing more than simple unordered lists (<ul>), the items are printed one below the other which wastes lots of space. The patch I came up with does only partially implement support for these tags: The items are correctly displayed within one line but I cannot figure out why there is so much empty space after each item. Perhaps somebody with a better understanding of the dw-code than me might have a look into the issue. If I am correct, the dw/textblock.cc is responsible for calculating the widths. Textblock::wordWrap() looks pretty promising as there is a variable (hasListitemValue) determining whether it is a list item and calculates values for lastLine->leftOffset and words->getRef(0)->effSpace depending on this state. --Tim

Re: even more cookies SECURITY

Hi, I want to start this 2010 year thanking all the people that have contributed to make Dillo what it is. It's been 10 years and a long way lays behind. Lots of people have shared their time/work/advice/help/money/. After all, what we have now is the addition of all those efforts. Thanks to you all!!!

The only problem I recall was the error message you reported with cookies and later seemed to be working somehow. Besides, AFAIS the repo is stable enough to start rolling the release process. BTW, the cookie story is frustrating. Generally speaking: vested interests strive to kill commodity technologies to introduce their own and henceforward profit monopoly-like. This happens everywhere in the area we deal with e.g. HTTP, HTML, SGML, XML, scripting, flash, java, video streams, audio, cookies, AJAX, etc. Remember that not even the big players were able (nor willing) to implement the SPECS they co-designed. Dillo's game so far had been to support a subset with emphasis on efficiency and privacy. The game is never solved, the point is to decide well where to prune (see bottom line). Speaking of technology: Ten years ago it was images and tables, the FTP, then CGI, then cookies (the stateless HTTP, now with state), then frames (which faded 5 years later), then SGML (which was replaced by XML), then XML (which never succeeded over HTML tag soup). Then CSS (which is necessary these days. Despite IE never gave much for it). Somewhere in the middle there was java (and java beans), but it died. Then Flash, then AJAX, then silverlight, the cloud... IMHO, beyond the hyped technologies "du jour", Dillo is relevant as long as it's able to serve as an efficient information gathering tool, with emphasis on privacy. -- Cheers Jorge.-

experimental patch: gnutls for the https dpi
by corvid＠lavabit.com 21 Jan '10

21 Jan '10

A few hours ago, I started to wonder how much trouble it would be to make https.c understand gnutls instead of openssl. The answer is: If you borrow liberally from the public domain code in the gnutls manual, then not very much! So here's a toy for anyone who would like one: http://www.dillo.org/test/gnutls.0.patch Now we'll _have_ to have a release soon, because we're accumulating so many things to play with after release...

Cookies performance
by Johannes.Hofmann＠gmx.de 19 Jan '10

Hi, I noticed that since the recent DPI update pages which use cookies load slower (e.g. fltk.org). Do others also see that? It could also be OS specific. Cheers, Johannes
