a list of what dillo2 runs on
by corvid＠lavabit.com Nov. 20, 2008

Nov. 20, 2008

I want to get the status of everything in order to update http://www.dillo.org/Compatibility.html for dillo2. Linux x86 - works DragonFlyBSD - works Linux x86-64 - Justus was and is making snapshots, but I don't know whether he uses them much. Solaris 10 - Justus reported that it was running, but I believe it was just a quick test. OSX - Jorge reports that it works but is currently flaky. *BSD - Some of the mailing list traffic in October was devoted to getting them working. Presumably it would have been mentioned here if they had stopped working since, but... other - no idea. Looking back at what I just wrote, let me clarify that I meant that dillo2-on-osx is flaky, not that Jorge is flaky :)

what crashes remain?
by corvid＠lavabit.com Oct. 3, 2008

Oct. 3, 2008

It's still possible to crash dillo if you click on a remote link and quickly click on some images to load them. Doesn't crash every time, but typically within four tries or so. I had assumed it was the same thing as whatever was wrong with the menu crash, so I'd ignored it. If I stick a_Bw_stop_clients(bw, BW_Img); in the DilloHtml destructor, I can no longer get it to crash, but I randomly got a "Cache_process_queue Caught busy!!!" while browsing earlier today, so there's something wrong with just doing that. (Assuming it's related; I'm not in the habit of getting that MSG.) I can't think of any other crashes, but I don't remember whether Johannes still gets bus errors.

an experiment regarding cross site request forgery
by corvid＠lavabit.com Oct. 3, 2008

Oct. 3, 2008

Cross site request forgery is the one where the bad person sticks an image tag or some javascript or whatever on a page, and your privileges are used to do something. So my latest little experiment: out of the image urls your browser sees that have queries (the '?a=b&c=d&e=f'), how many are - just advertisement trash anyway - things you want where the request would work just as well with the query removed (e.g. forum software that likes to stick session ids on everything) - things that wouldn't still work but don't really matter (e.g. user icons) - things you need Here's a little bit of code that tries rejecting them. (If dillo had an option for such a thing someday, I imagine it would have a form more like "don't automatically load, and make it easier to know what the URL is before you load it manually")

segfault -- callback + closed window?
by corvid＠lavabit.com Oct. 1, 2008

Oct. 1, 2008

I hit ',' a few times, going back past a page with a big progressive jpeg webcomic, and hit ^Q to close the window while dillo was thinking its way past that image. Got: Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 16384 (LWP 2782)] 0x080fc708 in fltk::Widget::redraw (this=0x81cb680, flags=8 '\b') at Widget.cxx:575 575 widget->damage_ |= DAMAGE_CHILD; (gdb) bt #0 0x080fc708 in fltk::Widget::redraw (this=0x81cb680, flags=8 '\b') at Widget.cxx:575 #1 0x0804f679 in UI::button_set_sens (this=0x82ce9d8, btn=UI_STOP, sens=0) at ui.cc:1109 #2 0x08054c59 in a_UIcmd_set_buttons_sens_cb (vbw=0x81ad858) at uicmd.cc:835 #3 0x080e47f9 in fltk::wait () at TabGroup.cxx:116 #4 0x080e489d in fltk::run () at TabGroup.cxx:116 #5 0x0804efab in main (argc=1, argv=0xbffffb44) at dillo.cc:127 Maybe that's just a part of life with callbacks...

source window's reluctance to show end of file
by corvid＠lavabit.com Sept. 30, 2008

Sept. 30, 2008

I've been assuming all along that everyone sees this problem, but then I don't think anyone has ever mentioned it, so I wonder whether it only shows up on my slow machine. Thus far it's always been easier for me to resize the window -- thereby causing whatever refiguring is necessary -- than to dig through TextDisplay to find out what goes wrong when line numbers are turned on.

Hi, Can somebody please make the dialog for closing a window with tabs open? -- Cheers Jorge.-

It is assuming that link numbers are always increasing, right? Can we assume this in dw/*? src/html.cc seems to be implemented currently in way that this is true. But perhaps we could/should reuse link numbers for equal destination urls in the future? Or someone might just choose hashes of the url string as link number. BTW. with both implementations I now see issues with this example: <html> <body> <a href="http://www.dillo.org">dillo</a> <a href="http://slashdot.org">slashdot</a> <a href="http://www.dillo.org">dillo</a> </body> </html> When opening the first link in a new window, it doesn't change color in the original one. When opening it in a tab, the first one changes color. After a reload also the second one changes color. Am I missing something? Cheers, Johannes

It helps the child widgets find their bw. e.g. search button, panel buttons, etc. They are nested in different ways depending on the panel shape choice so AFAIS there's no easy way to navigate up to the UI. One way solve it is to store the bw in the window's user_data(), thus a simple wid->window()->user_data() does the trick. Giving it some more thought, the danger of some function not belonging to the current UI geting the wrong bw is real, and it may end sending commands to the wrong bw. IOW: there's only one window for several tabs. When Tabs switch focus, the window()->user_data() is updated accordingly. If a background Tab requests its bw using window()->user_data() it will get the wrong one! (this may cause problems as the one reported by corvid.) If we can find an alternative method to get to a widget's bw (storing it in the CustTabGroup for instance), it'd be much better. -- Cheers Jorge.-

patch: show_msg=NO disable debug messages
by corvid＠lavabit.com Sept. 29, 2008

Sept. 29, 2008

tried turning off show_msg and saw how dillo is still somewhat chatty thanks to DEBUG_MSG. (Or would you prefer a show_debug_messages pref as suggested in dillo2rc? Hmm... thinking about the sentence "Generic messages (mainly for debugging specific parts)", I'd have to say that we use MSG for plenty of debugging messages and DEBUG_MSG for plenty of of-more-general-interest messages.)

Just think about: <html> <body> <a href="http://slashdot.org">slash<b>dot</b></a> </body> </html> After clicking, the dot is no longer bold. Cheers, Johannes
