dwb - a webkit web browser

Ypnose · 2013-03-30 10:50:20

Yes, dwb starts and displays pages but those messages are spammed in the terminal. With default webkitgtk from repo (1.10.2), everything is fine.
When I opened google.com in the current tab, I had this error too:

** (dwb:3439): CRITICAL **: void webkit_web_view_load_uri(WebKitWebView*, const gchar*): assertion `uri' failed

EDIT: If you need it, I can send you webkitgtk 1.11.92 compiled by me. It could be useful if you want to do tests.
Here the configure options I used: https://github.com/Ypnose/PKGBUILD/blob … t/PKGBUILD

i wasn't ever able to reproduce it but several people confirmed that disabling javascript fixes the issue, so i assume that it is a bug either in JavaScriptCore or in webkitgtk. Anyways, as long as i cannot reproduce it i cannot do anything to fix it.

I'm fairly certain that it's the adblockers and javascript. It happens more with privoxy than the built in adblocker. From http://www.privoxy.org/faq/trouble.html

This is probably a manifestation of the "100% cpu" problem that occurs on pages containing many (thousands upon thousands) of blank lines. The blank lines are in the raw HTML source of the page, and the browser just ignores them. But the pattern matching in Privoxy's page filtering mechanism is trying to match against absurdly long strings and this becomes very CPU-intensive, taking a long, long time to complete.

finally updated today the dwb and navigate search from google , said : google.com blocked domain. What ? before update work all things.

Try it with e.g. surf and see if it works.

Hi folks! I'm used to use this script under firefox to play a flash video with mplayer, but it doesn't work under dwb

mplayer $(lsof -p `ps x | awk '/libflashplayer.so\ /{print $1}'` -n 2>/dev/null | perl -lne '@F = split(/ +/, $_, 9); print "/proc/$F[1]/fd/${\($F[3] =~ /(^\d+)/)[0]}" if $F[4] eq "REG" && $F[8] =~ /\(deleted\)$/')

Do you know why?

No video is downloaded in /proc/***/fd/***

Have you tried the extension with dwbem that handles this?

Which extension? What's dwbem? Sorry but i don't know much about dwb

WonderWoofy · 2013-03-31 20:08:49

Ummmm.... it is mentioned repeatedly throughout this thread, and there is a man page for it... and it is in the "SEE ALSO" section of the dwb man page. Read a bit.

Army · 2013-03-31 21:27:55

I use

#!/bin/bash
for f in $(file /proc/$(pidof dwb)/fd/*|gawk '/\/tmp\/Flash/ {print $1}');do mplayer ${f%:};done

and last time I used it, it worked.

I'm starting to like this browser more and more, but I have only one problem. Whenever, I am logged in to facebook and try to navigate away to another URL, dwb becomes unresponsive. The only way to kill it is with the kill command or through top/htop. This doesn't happen before I log in: if I'm at the sign-in screen and I try to go to a different website, it'll work as expected. Facebook is the only site where this happens.

bloom · 2013-04-01 15:55:00

I've just updated and it seems dwb now has problems with the settings file being a symbolic link:

No settingsfile found: Failed to open file '../../.dotfiles/dwb_config': No such file or directory
Using default values.

However, the symbolic link has not changed and isn't broken.

EDIT
In fact it handles absolute symlinks fine.

I noticed something strange today: dwb is using 1.2GB of resident memory for only 2 tabs (neither of which have javascript or plugins enabled).

I've been opening and closing tabs in this particular dwb instance for about a day and a half, but there's only two tabs open right now.

I'm using the latest Arch package:

$ dwb -v
    This is : dwb
    Version : 2013.03.30
      Built : Mar 30 2013 10:48:20
  Copyright : © 2010-2013 Stefan Bolte
    License : GNU General Public License, version 3 or later

Is this normal? I haven't noticed it until this version.

karol · 2013-04-03 23:24:20

I get high memory usage after a prolonged use, even with just a few tabs. After dwb restart the memory usage is very low and will continue to climb as time goes on.
It has been always the case for me and it hasn't changed recently.

Please link to a post instead of writing 'see page n' because users can use a non-default numbers of posts per page - e.g. I use 75 posts per page and this whole thread has only 21 pages.
Do you mean https://bbs.archlinux.org/viewtopic.php … 1#p1247951 ?

Yep, that's the one. Sorry, I assumed that people who ask for features go to such lengths to read a bit of the other discussions that are going on at the time. I don't ask anybody to read 1500 posts to be up to date, but especially if the answer has just been given 3 posts before their initial post, that's when I get lazy in pointing out where to find it. Bad role model, I know… :-/

I've seen that post. 800mb for 18 tabs just seemed more reasonable than 1.2GB for 2 tabs, and I had never seen it go that high before. Just making sure it's not a problem.

Sorry, I wasn't aware of that. However, not the number of tabs but rather the time the browser was open seems to be the issue here… at least, that's also the pattern on my computer: If dwb was open a few hours and there's only one tab open (even if it has been cleared) it still might consume a few hundred MiBs…

portix · 2013-04-05 17:17:29

One memory leak is fixed in dwb-hg that affects closed tabs, but i guess memory consumption will never be low with webkitgtk.

mkaito · 2013-04-05 17:29:14

You've probably heard this one. Hitting "back" after browsing to certain pages lands you on the very same page again. I believe this has to do something with loading external resources causing double history entries... some pages, I have to 7H before I get back to where I was. This is an issue shared by all browsers based on webkitgtk, as far as I can tell, but is there anything dwb can do about it?

portix · 2013-04-05 17:43:49

You don't get on the same page again, webkit just doesn't render the new page, if you reload the page webkit will render the page correctly in most cases.

mkaito · 2013-04-05 17:55:27

I don't think that's the case. Prepending a count to the back command usually gets me to the right place.

A place where it always happens is when going from reddit to a imgur gallery. Please try it yourself and see if that's what you mean. Note that direct links to images hosted on imgur do not cause this behavior. It needs to land you on the gallery page.

portix · 2013-04-05 18:35:24

Do you have an example? I won't search on reddit for imgur links. I think it's webkit's fault anyway because dwb only modifies webkit's history when it loads content from a string, e.g. when browsing the local filesystem or for dwb:... sites.

mkaito · 2013-04-05 18:59:39

This one should do it: http://www.reddit.com/r/Eve/comments/1b … iness_and/

Click the link to the imgur gallery, then try to go back.

And yes, I'm almost certain it's webkit's fault. I was just wondering whether dwb can do anything about it.

portix · 2013-04-05 19:09:54

Works here as expected.
