an experiment using mbed TLS

by matlads＠gmail.com

Hi dillo-dev, Dillo builds just fine on mucosa, especially after I `brew install mbedtls` Problem is that, at start up, it reports Trusting 0 TLS certificates. Any idea how I can install some? It's odd browsing about without https these days.

What you'd wish it had. I had been using Firefox (and still do, for trusted sites that require javascript), but looked around for another browser when the option to turn off javascript was removed from the preferences dialog -- when javascript is so often the vulnerability behind exploits, I didn't want a browser hoisting in javascript from all over the Internet at its own discretion. (It is still possible to turn javascript off in Firefox if one starts from a script that invokes a prefs.js with a legacy `user_pref("javascript.enabled", false);', or from the internal about:config page, but:) Dillo was one of the few browsers without javascript, and when I checked it out, I found that I agreed very much with Dillo's stated philosophy. And it has been my principal browser ever since. In fact, along with an xterm and Emacs, it's one of the three apps always running on my machine. Things I like about Dillo: Dillo doesn't even include javascript. (I cringe a bit when there is talk on the list about the possibility of including it -- if it is included at some point, I hope that there will be a #define to exclude that code at compile time.) Dillo is small and fast, which is nice not only for general browsing, but when invoking it through, e.g., Emacs to open a link. Dillo let's me configure things the way I like, and when it doesn't do something I want, the code base is accessible enough that I can modify it to do so. (I had in fact already implemented the suggestions I made, but didn't share any patches because, even beyond being an amateur, my hacks tend to be on the ugly side -- the loading of images per page, for example, required adding #include "html.hh" to ui.cc, indicating that I am certainly violating some logic of organization and encapsulation.) Dillo isn't phoning home or doing anything else behind my back, and it let's me easily block ad and other such sites in domainrc. Dillo doesn't try to do all sorts of exotic things, or invoke external apps to do them, with all of the potential security risks. With other browsers, you have to do a lot of work to try to prevent this sort of automagical behavior, and even if it's possible, you aren't left feeling at all confident about having prevented it. Like you, I like that Dillo caches DNS lookups, but of course IP addresses change from time to time for legitimate reasons, so there does need to be a way to flush the cache. Johannes's patch is a good one, but I also still like the idea of using the cache until I need it to refresh. Of course, one could simply start a new instance of Dillo, but I also like that it caches pages in a way that allows me to open a link to a previously visited page off-line, without trying to reconnect and reload it. And -- possibly a unique personal idiosyncrasy -- I like to see links I have visited displayed as visited. Other than that, there really isn't any reason not to be firing up a fresh instance of Dillo whenever it is needed. And probably a lot of other virtues in Dillo that just aren't coming to mind right now. > Some things may be possible, others not, a few may be solved in different > ways, etc. Just learning about those key tasks, or improving a single one, > would be a big gain for all of us. > > Your feedback as a dillo power-user is not only welcomed, it's asked for! > > >> Thanks again for all your hard work! > > Ack! > > > @all: if you're a dillo power-user, let us know about it!

Wow, it's good to know it can last that long. What you describe here is very interesting, in a way I've come to suspect most users don't have the slightest clue. I mean, everyone of us (as dillo users) have *different* use cases. There's no way we can guess what other people are doing outside of our awareness realm. Now, you're not only a casual user, but one that uses dillo *a lot*, and appreciate it as an everyday tool. That being stated, we are very interested in knowing your use case, and all the details of it. There's potentially a lot we can learn from it, and also improve yours/and-the-generic user experience as a result of this learning. So please elaborate on why you like to have it running for that long time, what do you do with it, how you do it, what problem does it solve that other tools don't, why is it your choice. What you'd wish it had. Some things may be possible, others not, a few may be solved in different ways, etc. Just learning about those key tasks, or improving a single one, would be a big gain for all of us. Your feedback as a dillo power-user is not only welcomed, it's asked for! > Thanks again for all your hard work! Ack! @all: if you're a dillo power-user, let us know about it! -- Cheers Jorge.-

Interesting - here is another example of the issue that I discovered today: https://bz.apache.org/bugzilla/show_bug.cgi?id=59333 Great work going on with Dillo anyhow - thanks to all.

Thanks for the patch Johannes. Under the current workload, I guess I'll look at it in a couple of days. BTW, different use cases are very interesting. We usually asume our use case is generic. Dillo has thaught me several times that's not the case. I for instance, really avoid flushing the DNS cache as it is one of the slowest parts of my web browsing experience. Sometimes the ISP DNS server takes more time to answer than the page to load! I use another DNS but it's very noticeable, and the sites I usually browse seldom change their IPs (I've even thought of caching to disk, go figure! ;) So I'd like to know what's the use case behind this need. There's surely something on it (e.g. some site may want to distribute workload between different servers by changing IP, etc). One thing I know DNS queries are abused for is for tracking users. On the old dialup days, the DNS was very quick to answer, so I suspect something fishy going on when it takes so much time here on broadband... -- Cheers Jorge.-

I was just pointing out the issue; for myself, just commenting out the above line works just fine by reverting to the old behavior and smaller font size in the location bar.

Yes man. That was a quick patch (#4222 in Hg) for a larger font. I'll look at it after I finish a general rendering algorithm bug I'm working in. Please be patient. BTW, do you really need a font size that enlarges the location box? or would it be enough to clamp the font size to fit in? The second case is a much simpler patch. -- Cheers Jorge.-
