Feature request

by Jens Arm

Hi I love dillo much and I missed a feature which is very nice if you have more Browserwindows: All new browsers like Mozilla/Konquerer/Pheonix have the feature Tabbed-Browsing, would be nice if dillo have this, too. Jens

Segfault using text selection?

by Phil Warner

Hi, I have experienced several segfaults with dillo using the new text selection feature. I include two instances from gdb below. This happens when I select text while some page is loading (typically when I get impatient while dl'ing a site). I hope this is informative enough. Let me know if I can test it more.

Why not have compile time options to include or not include both the built-in http protocol support, and the option to use wget. That way, anybody using Dillo in an embedded application who just needs http support can use the built-in support, but anybody requiring additional functionality can use wget. John.

Such an "external program" already exists -- it's called wget. And if you wrote the dillo<->wget interface flexibly enough, you get https, ftp, and use of http proxies all for the price of one. Cheers, -- Ami Fischman usenet(a)fischman.org

No, the event is (since recently, for selections) sent to the toplevel widget, although its position is outside of the allocation of the latter. (If your assumtion would be correct, a_Selection_button_press would never be called :-) The problem is that the DwIterator, from which a DwExtIterator is constructed, points to a widget (the DwEmbedGtk containing the button), which is the last content in the page. a_Dw_ext_iterator_new tries to move forwards (since it must never point to a DW_CONTENT_WIDGET), and, of course, fails. Obviously, the fix is to move backwards then. Sebastian

It is simpler than 1) and 2) ! As SSL has a high priority on my list, it would be a matter of writing an external program that does https (given the URL), retrieves the resource, performs any other required tasks and reports it results somewhere. That is, I'd make all the necessary bindings/extensions in dillo's core to accomodate the plugin. AFAIU, the most basic communications required between dillo and the https dpi are: 1) -> Send the https URL to retrieve 2) <- Maybe make the user confirm the certificate acceptance 3 <- https resource Please inform me about any other required communications. As for developing the prototype, just as stated in the dpi docs. assume you have the answer from dillo and go on! That's all. Hope this helps Jorge.-

Segfault with newest selection code.

Hard to reproduce, though. Here's how to reproduce it: Load the attached page from the location box, then focus the viewport by clicking past the end of the page. I guess that as there're no widgets in that space, the iterator code gets a NULL and from there comes the segfault. Cheers Jorge.-

Re: [Dillo-dev] A Question and 2 Requests

by Jorge Arellano Cid

On Sun, 16 Mar 2003, William Trenker wrote: > How do I tell exactly which sub-version of Dillo is running? I was running Dillo 0.7.1 and it crashed when I tried to save a bookmark. I wanted to be sure I had the latest Dillo before reporting the problem. I see that Dillo 0.7.1 has two sub-versions, 0.7.1.1 anmd 0.7.1.2. When I downloaded and extracted the latest tarball the resulting executable only shows 0.7.1 for the --version option. If you have the 0.7.1.2 tarball, you have the rigth one! The 0.7.1.2 version fixes the bookmark crash problems. If you still experience crashes with it, you've found a BUG so please report us howto reproduce it in order to fix it. Now, provided that I haven't received complaints in the past days (and there're a few thousand downloads), crashes may be due to a compiler or libraries problem... > My requests are both based on my experience with the Opera browser. First, is it difficult to change Dillo so that I can copy-and-paste text from the browser window? We have a dillo doing copy&paste in the CVS!, but it needs some testing and fixing because it crashes very often. Most probably the next release will have the feature. > I find it very handy to copy text from a web page to paste into a document, or an email, or whatever. Second, I really find Opera's mouse gestures for going forward and back very handy. To go to the previous page (back) you hold down the right mouse button and click the left button. To go forward you hold down the left mouse button and click the right button. With a little practice you can move back and forth between pages very quickly. Currently you can use "," and "." or "Backspace" and "Alt+Backspace" as back and forward shortcuts. Those are in the keyboard, I know, but they may help you in the meanwhile. Finally, the main reason for not incorporating new features is lack of manpower. The main developers are buried under a list with lots of high priority tasks (for instance my list has more than 30 items appart from the area I decided to work now!). Patches would be a lot easier to integrate if their authors took the time to do the toilsome task of checking them against the respective SPECS and RFCs, but most of the time they don't. > Thanks for a great browser! :-) Cheers Jorge.-
