(_and_ I could have run many more trials, but the idea that assert() was even capable of reaching that high was alarming)

a little experiment in showing form encoding as a tooltip
by corvid＠lavabit.com Sept. 5, 2008

Sept. 5, 2008

Currently, there's a MSG that tells you what encoding a form was submitted as -- once it's submitting it. Obviously that's of limited usefulness when you want to know beforehand what will happen to any Japanese that you might type in, but on other hand, so many pages have forms that MSGs ahead of time would be annoying, besides the fact that a page may have multiple forms with different accept-charset attrs... Add to that the fact that one has to learn the hard way that you should only paste utf-8 into dillo2 and not, say, windows-1257. (and latin-1 works because fltk assumes it's latin-1 and does the conversion) So my quick little experiment: text/password/textarea form controls display a tooltip that reads enter: UTF-8 when UTF-8 will be submitted, and enter: UTF-8 send as: [some other encoding] otherwise. And it would clear things up for every person who tried to use google.com and wondered why non-latin-1 wasn't working when the oh-so-glorious dillo2 is supposed to be all UTF-8ed up. After all, it works in Firefox, right? (I've read that google pulls this idiocy with all of the little browsers. w3m, elinks, etc. Ignores the Accept-Charset header and does what it wants based on the User-Agent.) A different option might be to have a form popup menu to show info such as submission encoding, hidden inputs, and so on. As for the code, unfortunately I have setTooltip()s all over the place because Style's Tooltip field is for real tooltips, not for char*s to stuff into pre-existing tooltips such as the fltk widgets have.

Keyboard scrolling and focus patch

Currently dillo2 uses window, so Ctrl-N can open a new window. It would have been convenient not to change the current code base, and to reuse that already tested part for both tabs and new windows (with the idea of being able to open tabs or new windows with the same code). It may be possible by switching class UI to derive from Group, and to add an enclosing window only when necessary, and thus arrange for widgets inside Tabs and Window for windows. The problem I foresee with the latter scheme is messing with the event passing between widgets and windows... I'll have to experiment with it, and get some working code. Now, if *somebody* wants to help then, that'd be great! ;-) -- Cheers Jorge.-

Keyboard scrolling and focus patch
by jcid＠dillo.org Sept. 4, 2008

Sept. 4, 2008

Hi there, Finally a patch for fixing keyboard scrolling, and focus change with the keyboard, was committed. I had hopes to be able to commit before the release, and so I'm happy. :) Now switching focus from the viewport to the location bar, using the keyboard, works consistently (Try TAB/Shift-TAB) and also the scrolling keys (Up, Down, Left, Right, PgUp/b, PgDn/space, etc) are kept in a responsive state. It's been a long time, and I almost forgot the nice feeling of scrolling with the keyboard (e.g. try the space bar to skip past the links menu most pages have these days). Please test, and enjoy. -- Cheers Jorge.- PS: I've also made some experiments with tabs, but it seems FLTK2 has problems to handle window widgets inside the tabs...

patch: make image inputs less of a special case
by corvid＠lavabit.com Sept. 1, 2008

Sept. 1, 2008

- have the complex button resource remember its click x,y. - just use the Activate signal instead of Clicked - don't have to carry x,y through so much of the form code. - use appendValues instead of that special case in buildQueryData. (Jorge: I have another version of the form action url display patch, but this jumped ahead of it somehow)

patch: make prefs.c and dillorc2 consistent
by corvid＠lavabit.com Aug. 26, 2008

Aug. 26, 2008

The proposal here is to have everything commented out in the rc by default, and show what the default settings are so that people don't have to spend as much time experimenting when they want to configure their nifty superbrowser. When resolving inconsistencies, I generally picked the rc setting when uncommented, and the prefs one otherwise. Figured it would be a fair approximation of what Jorge might accept... Also, I remember Jorge once saying that maybe it should be named dillo2rc instead of dillorc2. I think so too.

towards a consistent UI
by Johannes.Hofmann＠gmx.de Aug. 18, 2008

Aug. 18, 2008

Hi, I really like the way Ctrl-l now just selects the current URL in normal mode avoiding a dialog window. In fullscreen mode however, the short switch to normal mode to enter the new URL requires a complete redraw of the page contents. Also the contents "jumps" down for the time the location bar is shown. This can be distracting. Do we really want to kill all uses of dialog windows? We still have "Search the Web" anyway. Also the location of the "IMG ON/OFF" button seems a bit arbitrary. How could a consistent user interface of dillo look like? Here is my proposal - just to start the discussion: * Everything is accessible via the menubar and via keyboard shortcuts. The shortcuts are shown behind the menu entries. * All shortcuts are configurable. * No more img on/off button. One can use a menubar entry or keyboard shortcut instead. * The "Search the Web" button should be just as all the other buttons ("Back", "Forw" ...) and be configurable of course. Perhaps a single config option like: panel_buttons="back, forw, home, reload, save, stop, book" * The "HTML bugs" button in the status bar is ok. It shows the bug-state of the current page. * "Search the Web" opens the start page of the selected search engine (e.g. google.com) and selects the search text field. I'm not sure about that, but it avoids the dialog window and it makes clear to which search engine the query is sent. The additional page load for the empty search page is only required once - then it's cached. * In fullscreen mode "Ctrl-l" opens a dialog window again. Any better solution? Cheers, Johannes

Dillo in OSX

Aug. 15, 2008

Hi again Found the problem... had some old fltk includes in /usr/local and was installing the cvs to /usr ... so dillo was mixing both includes and breaking the compile. its fixed now, thanks for the help, specially Johannes :) higuita -- Naturally the common people don't want war... but after all it is the leaders of a country who determine the policy, and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked, and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same in every country. -- Hermann Goering, Nazi and war criminal, 1883-1946

Please help me on this...
by jcid＠dillo.org Aug. 14, 2008

Aug. 14, 2008

Hi there, Looking to a future dillo2 release for the public, I was wondering about the main drive behind dillo2. I mean, in this years of Facebook, WebKit, Flash, propietary video codecs, etc. what's the main point behind dillo2? From the objectives: 1.- The democratization of internet information access. 2.- Personal security and privacy. 3.- High software efficiency. The first one is interesting to analyze along the lines that dillo allows to search for tons of information spread through the Internet using low HW requirements and low bandwidth as a dialup. This is reassuring as dillo efectively enables information access to any person under such constraints. The second one is partly attained by not writing to HD and by a non-existent scripting support. The third one is the one to brag about. ;-) Since some time, the thought that enabling dillo2 as a help browser could also bring local information (i.e. in HD) closer to the user came as a powerful one. Having an app. that pops-up in a second and that's quick, responsive and easy to use is certainly a strong drive for a person in search of information (that's why I'd like to see it inside Debian as a help system). In the near future, I'd like to have CSS and proper floating text rendering (DIV element), plus an API as a help browser. There're countries where paying Universitary studies is the state's burden. If a citizen doesn't want to study there, it's a choice. I think the same may happen with dillo, once people know about it, they can choose to use it or not. While thinking about it, these comments surprised me: "Slashdot | What Do You Want On Future Browsers?" http://tech.slashdot.org/article.pl?sid=08/06/30/1845201 (yes, give them a read!) (They're talking from a full featured Firefox basis. I don't know how may of them would like to use something like dillo) Behind a project like ours, there're two communities: developers and users. The main factor to push forward the project is developers and their motivations (in a commercial environment what pushes the development is the money invested and the profit margins/strategy sought). That's why I'm asking you to help me with your views, needs visions on the future of dillo2 these days. With regard to the user community, I'd love to have some feedback from them, but I guess we need to release dillo2 first! :-) -- Cheers Jorge.-

selecting multi-byte characters
by Johannes.Hofmann＠gmx.de July 13, 2008

July 13, 2008

Hi, as you may have noticed, there is a problem with selecting multi-byte characters. If you enlarge the selection so that e.g. '?' is at the edge of the selected text, the character changes in weird ways. This is due to the Textblock::sendSelectionEvent() code that simply uses charPos++, and charPos-- whereas it should do something like utf8fwd() or utf8back() from fltk. The problem here is that we can't simply use fltk functions in textblock.cc as it is independent of the GUI toolkit. Any ideas how to solve this? I thought about adding wrappers to fltkmisc.cc but that's also a bit ugly... Cheers, Johannes

iterator related bugs
by Johannes.Hofmann＠gmx.de July 4, 2008

July 4, 2008

Hi, while looking for the reason of the rare selection related crashes I found something that seems like a severe bunch of bugs in the iterator code. It might be related to the crash, but I'm not 100% sure yet. There is this innocent comment in front of the DeepIterator constructor in iterator.cc: If you want to continue using \em it, pass it->cloneIterator(). This means, that the DeepIterator constructor eats up the Iterator it get's passed a pointer to! The evil thing is that every method that passes one of it's arguments to the DeepIterator constructor inherits this property, e.g: DeepIterator::createVariant() and as a consequence also: SelectionState::switchLinkToSelection() and SelectionState::adjustSelection() In Iterator::scrollTo() Iterators that are used after being passed to the DeepIterator constructor. In SelectionState::buttonRelease() an iterator that has been passed to switchLinkToSelection() might be used afterwards as argument to adjustSelection(). I would propose to change the behaviour of the DeepIterator constructor and always clone its input Iterator. Better be safe than sorry and the fact that there is already several bugs related to this shows, that the current behaviour - even if it's documented - is really dangerous. What do you think? Cheers, Johannes

Hi Enrico, Hi Everybody, It took some time to get back to you, but the topics raised are non trivial. Let's start with the simpler one: > [Keyboard shortcuts] > > I believe one of the important things that we could support is > > custom keyboard shortcuts in dillorc. > > ACK. Maybe would should go the way Mutt does: it internally > works with commands, and keystrokes are mapped to commands. Perfect for me. If you can patch dillo to do that, it'd be great. > [C++] > > i. - Increase the development team by adding 6+ new developers. > > ii.- Getting more involved with other projects. > > you can add me, as long as no C++ stuff is involved. > (don't like it's overhead). I also don't like C++ and its complexity! FLTK2 is in C++ so we had to interface with it. The idea was to keep C++ to a minimum set of features. OTOH, windowing systems and widgets are quite well suited for the object oriented approach, and in some places it gets simpler than dealing directly with inheritance in C (as with GTK1). > [Translations] > I'm already working on German translation.

A simple way is to isolate those "certain pages" into a fixed URL scheme (e.g. localhost:8081/admin file:/etc/read_only_directory/) and to check that signature from the dpi. For this to work, you have to send the "requesting URL" to the dpi by using dpip. > [9P] > You might like have a look at Plan9 and how things are done there. > We can learn really much from it :) I gave a read to some docs. and it looks quite interesting. > [...] > I'd prefer a more generic approach: making everything available > via 9P and let separate programs work on that filesystem. > This also allows lot's other funny things, eg. an HTML external > editor which directly operates on an document within an dillo > viewer ;-) The 9P way of interaction is powerful. I like the idea of interfacing to a Javascript VM with 9P, and reusing a proved protocol instead of having to extend/debug dpip. Now, being a 9P newbie, how much (in LOC or KB) does it add to become a 9P server or client? This is my main concern. I'd like to see a sketch of a Dillo help system design using 9P. Currently dpid would provide a Unix socket to command Dillo, and 9P does something quite similar but more generic. The idea of being able to remote-control Dillo from a simple application/script with a 9P interface is more than interesting. For instance: Load URL, Reload, Stop, Open New window, Back, Forward, images on/off, etc. AFAIS, we'd need to make dillo work internally with commands, and then exposing that interface for the external world. If the dillo help system design looks interesting we can start from there. Obviously you have given it some thought in your project so please share your ideas with us. Obviously using 9P to remote-control dillo seems like an overkill, but when it comes to Javascript, or interfacing to external apps. as an HTML viewer, or serving as a GUI, it looks reasonable. Comments are welcomed. -- Cheers Jorge.-

what's next
by Johannes.Hofmann＠gmx.de June 30, 2008

June 30, 2008

Hi, for me dillo-fltk is pretty stable, fast, and generally a joy to use. I still see the following issues: * In rare cases the screen contents is not properly redrawn due to the redraw optimization. I'm looking for a way to reproduce it. Anyone else seeing this? * The cursor is not always updated properly when over a link. This happens while page is rendered and also when drag-scrolling with the middle mouse button. * The bus error I had posted about is still there and I have seen it once as a segafault with similar stack trace on a Linux box. I still don't have a way to reproduce it though. Any other problems or missing features? Jorge, what do you think about officially releasing what we have in the near future? Or do you prefer to wait for the big stuff (like CSS)? Cheers, Johannes

[patch] use prefs.vw_fontname
by Johannes.Hofmann＠gmx.de June 27, 2008

Hi, attached patch uses prefs.vw_fontname instead of hardcoded "Bitstream Charter" in web.cc. Thereby it avoids opening "Bitstream Charter" if it is not selected in dillorc. This saves about 500k in initial startup size with --disable-xft It hardly saves anything in the xft case. I don't know why. I would have expected it the other way round.... Cheers, Johannes

Memory usage

Hi there, I've been reviewing memory usage these days, and found some weird numbers that I'd like to understand. Taking the huge mysql page (13MB), I made the following memory measures (with ps). Load a bare dillo, load the simple directory where the huge page is located, then the huge page, then back, then forward, back, forward and back. I did this for dillo2.19Jun, dillo2.21Jun, dillo-fltk (with zone allocators) and dillo1. All in GNU/Linux with image_off.

Once back from the huge page, I'd expect memory usage to drop to what it was before plus the 13MB of cached data, plus some KB of overhead, BUT the RSS keeps near 90MB. This happens with dillo1 too. My thoughts: * If this memory is not freed, it'd be great to find the huge leak. * If it's freed but not returned to the OS., dillo would consume as much memory as the biggest page it has loaded. Clearly not a desirable situation. * It may be that the O.S. knows it can claim back this memory when necessary but prefers to keep it assigned to the same process until it finds better use for it. ------------------------------------------- Huge page with different memory allocators: ------------------------------------------- %MEM VSZ RSS TTY STAT START TIME COMMAND 5.4 134912 113740 pts/17 S+ 18:56 0:02 ./dillo-fltk step: 2x 5.4 134916 113752 pts/17 S+ 18:57 0:02 ./dillo-fltk step: 2x 5.4 134828 113660 pts/17 S+ 18:58 0:02 ./dillo-fltk step: 2x 5.0 114940 105432 pts/17 S+ 18:53 0:02 ./dillo-fltk step: 1 5.0 111976 105488 pts/17 S+ 18:54 0:03 ./dillo-fltk step: 1 5.0 114872 105416 pts/17 S+ 18:54 0:02 ./dillo-fltk step: 1 5.1 117796 106436 pts/17 S+ 18:59 0:02 ./dillo-fltk step: cst 5.1 117568 106404 pts/17 S+ 19:00 0:02 ./dillo-fltk step: cst 5.1 117820 106460 pts/17 S+ 19:00 0:02 ./dillo-fltk step: cst This data comes from a memory usage reduction by tunning the simpleVector memory allocator.

back to that SELECT segfault
by corvid＠lavabit.com June 23, 2008

June 23, 2008

In SELECT, if standard_widget_colors is set, color and backgroundColor are set to NULL. This tells FltkResource::setWidgetStyle() to leave the colors on the widget alone. If an inline element inside a SELECT calls style->color->getColor() or style->backgroundColor->getColor(), we get that crash. This currently means FONT and IMG. OBJECT and A would as well if that a_Color_vc code were uncommented. options: - four IN_SELECT tests. - letting Html_stack_cleanup_at_open() be called for inline elements in order to close the SELECT or something if IN_SELECT and the new tag isn't OPTION or OPTGROUP. - generating our own standard widget colors to put into color and backgroundColor. I don't like the first one because someone innocently adding a getColor somewhere in the future will never know about this danger. (a good example would be adding the a_Color_vc to open_frame())

Hi there, - Changed Textblock::addText() to internally allocate its text string, making the memory handling opaque to the caller. Does anybody remmeber the topic of addText() deleting a malloc'ed block of memory? I decided to make the change for API cleanliness/correctness and set the Textblock do the whole memory handling (i.e. now the Textblock is the one that allocates/deallocates the text string). The HTML parser was adjusted a bit to keep its old performance. -- Cheers Jorge.-

Hi is anyone else seeing these rare bus errors? This is not new and happens every now and then. I'm trying to track it down, but it would be helpful to have a method to reliably reproduce it. Cheers, Johannes BTW: It's currently the only type of crash I noticed. Program terminated with signal 10, Bus error. #0 0x28595b1a in ?? () (gdb) bt #0 0x28595b1a in ??

[patch] move highlighting data into Textblock
by Johannes.Hofmann＠gmx.de June 20, 2008

June 20, 2008

Hi, as promised here comes a patch to move highlighting information from struct Word into Textblock to save memory. I had to change the semantics of the highlighting API slightly (see comments) to ensure that the highlighted part is always contiguous. Here are some measurements (with load_images=NO): Page dillo-fltk patched_dillo-fltk dillo1 firefox ============================================================== splash 7240K 7236K xslt [1] 15016K 14220K freebsd [2] 70264K 58084K mysql [3] 186M 148M 232M 200M Obviously the difference is mostly visible on large pages. And firefox is pretty close regarding memory usage. However it needed more than 3 minutes to load the local mysql page compared to 6 seconds for dillo-fltk! Please look out for possible highlight related regressions. Cheers, Johannes [1] http://www.w3.org/TR/xslt [2] http://www.freebsd.org/doc/en/books/handbook/book.html [3] http://downloads.mysql.com/docs/refman-6.0-en.html.tar.gz
