[Dillo-dev]Test for socklen_t in configure.in
by Jorge Arellano Cid April 30, 2004

April 30, 2004

Hi there, Our configure.in is in need of a test for socklen_t. I thought this one could be a good one: dnl ------------------- dnl Check for socklen_t dnl ------------------- dnl AC_MSG_CHECKING(for socklen_t) AC_TRY_COMPILE([#include <sys/types.h> #include <sys/socket.h> socklen_t x; ], [], [AC_MSG_RESULT(yes)], [ AC_TRY_COMPILE([#include <sys/types.h> #include <sys/socket.h> int accept(int, struct sockaddr *, size_t *); ], [], [ AC_MSG_RESULT(size_t) AC_DEFINE(socklen_t, size_t)], [ AC_MSG_RESULT(int) AC_DEFINE(socklen_t, int)])]) but my autoheader complains... Can someone please complete the patch, I'm currently chasing a segfault bug I found... TIA Jorge.-

[Dillo-dev]Preparing the 0.8.1 release
by Jorge Arellano Cid April 28, 2004

April 28, 2004

Hi guys, 0.8.1 is getting closer every day. It will feature what's currently in the CVS (basically the improved HTML bug detection and rendering). I'd love to be able to switch this dillo version from alpha to beta stable, but for that there's a lot of testing required. That is, the new parser (going to lots of sites and asserting there're no crashes), and the recently found problems with puppy linux and downloading and FTP (has anyone experienced trouble with these dillo plugins on their systems?). Please test our current CVS hardly, and tell us how it did. Thanks to Jim, who was the first one to send some feesback: > Wow! I can see a big improvement, lots of sites that rendered readably, > but 'iffy', are now much clearer and cleaner. Cheers Jorge.-

[Dillo-dev]what should do after the window is scrolled?
by Lei Jin April 27, 2004

April 27, 2004

After the window is scrolled, should the new contents of the window be redrawed by the code written by human? Can we output the whole contents to a place, then when the window is scrolled, we only need to updated the visible rectangle parameter? --------------------------------- Do You Yahoo!? 惠普TT游戏剧，玩游戏，中大奖！

[Dillo-dev]install-dpi-local missing?
by Livio Baldini Soares April 26, 2004

April 26, 2004

Hello everyone, Long time no see, I know, I know... My life has been a (wonderful) big roller-coaster for the last 1 to 2 years, and it seems that the remainder of this year will be the same. Anyways, just wanted to try to report that reading the README file, one gets the impression that an "install-dpi-local" script should exist to install the dpis in your ~/.dillo/ directory for you. I have googled for it, and tried searching in the CVS ATTIC with no success. Things are working for me just fine, because I know how/where to copy the dpi files, but I can imagine that some of our users might be frustated, or require additional assistance. So, before releasing 0.8.1 it might be a good idea to fix the README, explaining what is needed for a "local" install, or even better, resurrect the install-dpi-local script. best regards to all!

[Dillo-dev]About porting Dillo to FLTK.
by Jorge Arellano Cid April 24, 2004

April 24, 2004

Hi there, We've had long email threads (between our core developers and some FLTK core devs.) dicussing about how the port of dillo to FLTK could be done. We've explored different paths (in abstract) and posting all the threads to dillo-dev would add more to confussion than clarity because each one was explored as it were the chosen one. For simplicity and to keep all the developers in dillo-dev well informed (and certainly inviting the interested ones to take part in the process), I prepared this recapitulation about the more relevant issues. It's a long document with a lot of information. Cheers Jorge.- PS: Previous background on this topic can be found at dillo-dev's archives: http://www.dillo.org/search-dillo-dev.html. For instance: search for "FLTK" by "jcid" sorted by "Relevance". This will not only bring my posts but also the ones from Michael Sweet that I forwarded to dillo-dev. ---------------------------------------------------------------- > [Sebastian] > Furthermore, I have plans to extract at least the core of Dw, and make > an own library of it.

> > the problem is dpid won't start in my custom Puppy Linux > > distro. Jorge, Thanks for the feedback. Now that I have dillorc file, dpid does load, but it still isn't working. If I start dillo from the commandline, and enter a url https://www.paypal.com, nothing at all happens in the browser, no error msg even.

[Dillo-dev]FTP

Morning all, Seeing as someone has mentioned 'FTP', I thought I would get in here. I cant seem to FTP with dillo. If I type is ftp://ftp.somewhere.com it will just hang there. If I type in ftp.somewhere.com it will take me to http://ftp.somewhere.com. So tell me, how do you FTP with Dillo? I am using CVS build. Thanks, -- Pete http://milneweb.com http://nomorevirus.com

Dillo has been in Puppy right from the start (which was about one year ago).
