A Dillo-Win32 update

I meant to reply sooner, and got sidetracked with other things...

It's been a while since I've run Linux, but I vaguely remember dbus's internal security/permissions were a nightmare. I'll admit, I'm not the biggest fan of DPI anyway -- relying on complex interprocess communication even for such simple things as local file browsing seems like more trouble than it's worth. It's better than the other way around, re-implementing operating system functionality inside the browser (as a certain search giant has), but I'm not yet convinced the advantages truly outweigh the implementation hassles. >> On a related note, is there any reason not to cut DPI out of the >> download system, i.e. just invoke a separate downloader process >> directly?

Well, I meant that more in the sense of "since the downloader's a separate process anyway, why go through DPI at all?" >> Or is something more passed through than just a URL? > > Maybe the target directory&savename.

I wrote my own downloader, and patched Dillo so it calls my program directly, bypassing DPI. (It also bypasses the Dillo file dialogs, since my program displays its own.) So far everything seems to be working nicely. I've only implemented the patch for Windows so far, and it needs a bit of cleanup, but if you're curious you can see it here: http://dillo-win32.sourceforge.net/files/dillo-r1705-dlgui-20100930.diff and the downloader itself: http://dillo-win32.sourceforge.net/dlgui.html I'm tempted to port Dillo to libcurl now, since it works so nicely in my own program, and seems like it would be much more portable (and stable, on Windows) than the current implementation. It would also allow for easier implementation of other protocols, like HTTPS and FTP. Any thoughts? ~Benjamin

I haven't used dbus, but it's used in GNU/Linux by some big players so I guess it stabilized [1]. Any inter process message- passing lib will work, but implementing it well is a hard task, that's why I suggested dbus (it has undergone lots of testing). Probably there's a better candidate in the embedded area.

Before it, we used a call to wget from a separate process too. You're welcomed to hook your own preferred application, that's the idea of dpi. > Or is something more passed through than just a URL? Maybe the target directory&savename. I don't remember well... You can make the dpip functions log the messages to a file without much hassle, and see what actually happens. -- Cheers Jorge.-

I'm not sure how cleanly it could be packaged, or whether it would run on Windows 9x (one of my goals is to support all the way back to Windows 95). I also have some personal dislike for it, after dealing with much dbus-related breakage in my Linux development days. I do appreciate the suggestion, though, and if you think it could work, I will certainly look into it. On a related note, is there any reason not to cut DPI out of the download system, i.e. just invoke a separate downloader process directly? I'm considering implementing that at least as a temporary solution, using my own self-contained download tool. Or is something more passed through than just a URL? Thanks again, ~Benjamin

The dpi framework works with isolated processes. A third option could be to make an alternative implementation that works in Win. For instance, is there a dbus port running in Win*? -- Cheers Jorge.-

The browser patch is about as stable as I can get it, so I thought I'd send it in for your consideration. First the patch, then my comments: http://dillo-win32.sourceforge.net/files/dillo-r1705-win32-20100913-merge.d… I'd consider this "merge-ready" in terms of completeness, though I haven't much tested stability, and I'd need your opinion on coding style. This is a long patch (~1740 lines), with a lot of separate but closely-interconnected changes. I'd split it into smaller subpatches, but I'm not really sure how practical (or possible) that would be, so my apologies in advance for the length. I've run into a major impasse with DPI. Simply put, DPI is not portable to non-Unix systems. Specifically, there are two main problems as far as Windows is concerned: (1) lack of Unix signals, and (2) non-interchangeability of file and socket descriptors. Since I'm aiming for a native port, an emulation layer such as Cygwin is absolutely not an option. I'm faced with a bit of a dilemma here. The two options I see are to either redesign DPI, or ditch it altogether; and I don't think anyone is too keen on either idea. I've considered a fork, but I'm opposed to the idea on both practical and philosophical grounds (my goal's to help, not to hurt upstream). Any suggestions? Thanks & cheers, ~Benjamin
