I need to play a bit more to see how it "feels". Yeah, I had also considered that, and agree it might be better to leave the save button. It could result in an unexpected surprise to users upgrading to a new version and saying "Hey, where's the save button!". Regards, Alex

I attach two screenshots, one (zoom.png) with the icon background set to the same color of the menu so the alpha is blended properly (but the icon is not transparent). And another one (zoom-alias.png) with the alpha cutoff at half, so alpha values less than 127 are converted to transparent pixels. This one shows some aliasing in the borders, but it works fine if you change the menu color. Not sure if there is a good solution to this problem, other than manually making the aliasing work well with a sharp border. The other icons cleverly avoid this problem by doing rectangular shapes. I'm also considering leaving the save button by default for now, and moving the zoom button to the right, so we preserve the "muscle memory" of users. I need to play a bit more to see how it "feels". Best, Rodrigo.

By "contains" I mean that $HOME cannot be inside save_dir: bad: save_dir=/ bad: save_dir=/home bad: save_dir=/home/<theuser> ok: save_dir=/home/<theuser>/foo ok: save_dir=/tmp Here is a very simple check (doesn't handle /../ and other problems): const char *home = dGethomedir(); const char *save = prefs.save_dir; int nsave = strlen(save); int nhome = strlen(home); if (nsave <= nhome) { /* Prevent save_dir="/home" and save_dir=$HOME */ if (strncmp(save, home, nsave) == 0) { MSG("save_dir cannot contain home\n"); exit(1); } } Best, Rodrigo.

Sorry, I guess this is the part that confused me: "(or any directory that contains $HOME, like /home)" I agree with it, just not sure how to implement while still allowing a save_dir like '$HOME/Downloads', or '/home/user/Downloads'. Maybe it's a simple thing, but any help would be appreciated! > >Not sure I understand what this achieves. So '/home/user' would be > >blocked, but '/home/user/foo' would be allowed?

I think it's unlikely that a user would explicitly choose $HOME as save_dir, but agree that it would be reasonable to take the precaution just in case. Thanks, Alex

Hmm, I guess that makes more sense. I was thinking we could read the preferences only from Dillo, then unveil accordingly, and then all DPIs would already get the unveiled environment. But as you comment, on the exec() the unveil will reset, so we will need to re-read the dillorc file again. I think this is also a good approach in case someone runs the dpid by hand, so it adheres to what dillorc says. >> Maybe for now we can add a simple implementation of the parser just to >> parse the "save_dir" and the new "enable_unveil" (or similar) option, >> like dpid is doing for dpi_dir. > >Ok thanks, I will try to use that as an example and see if I can get >anywhere with it.

Yeah, but there may be a lot of other unknown directories we don't want Dillo to access to (~/.config, ~/.cache, ...). So I think is a good approach to block all directories in home, except the downloads one. Another attack may involve encrypting ~/Pictures and asking for a ransom, so we should prevent any access to home that is not required. Best, Rodrigo.

Debian package endorsement request

by Rodrigo Arias

Hi all, I've been trying to update the Dillo Debian package from 3.0.5 to the 3.1.1 version of our repository: https://github.com/dillo-browser/dillo As commented on Fediverse by the maintainer of the Debian package, Axel Beckert (in CC), it would help having an endorsement from previous developers, so we can avoid a xz situation due to the change in upstream: https://fosstodon.org/@xtaran@chaos.social/112909239587911469 Here are all the changes among 3.0.5 and 3.1.1, which contain a lot of commits from Sebastian: https://github.com/dillo-browser/dillo/compare/3.0.5...v3.1.1 And here since the last commit from the original mercurial repo: https://github.com/dillo-browser/dillo/compare/c9b817f5bb8ef2060aa36ebb5b08… I'm adding the dillo-dev mailing list, so we can have a public record, in case we have a similar trust problem in the future. Thanks in advance, Rodrigo.

Perhaps it's something configuration specific on your end, it would be helpful to know what kind of operating system and desktop environment you are running. Does the problem ever happen with other programs, or just Dillo? Have you made any changes in dillorc, like custom fonts or other display settings? Regards, Alex
