Tell me, if I recall, there is a way to view frames in Dillo...correct? Would love to use it for Squirrelmail. Would actually be willing to use another web based, imap mail client too. -- ~~~Pete~~~ http://milneweb.com http://nomorevirus.com

Yes, that's the right way to do it, but I don't know how yet :) I commited a patch that tests for gcc version 3. Please test it and tell us. Cheers Jorge.-

Yes, probably because rendering is done when idle. Thanks Jorge.-

It does partly! (with the dpi-cache patch I'm developing). I'm planning to develop https.dpi as a dpi server so it can directly link against SSL lib or GNU TLS, instead of using wget. This ends the forking and allows for an easy implemetation of connection caching. BTW, https pages render OK with my tree, it's just the lack of reuse of the same connection what I suspect keeps it from working fully. I need to test a bit more too. Note: is there anybody here interested in working on the https dpi. I can quickly make the base (dpi server instead of filter) and then is a matter of knowing SSL or TLS and start implementing connection caching (no need to know about dillo internals). > [...] > > > The idea is interesting.

It needs polishing but illustrates the idea pretty good. You'd be surprised at how simple it is. BTW, it was developed by a complete newcomer to dillo I was advicing. I'll send it to you and Sebastian (to illustrate part of a response I owe him about preferences). List: I'll review the latest version and decide whether to share it in its current state for polishing. The required knowledge to work on it is minimal: just GTK+ (the server part is already done).

Re: [Dillo-dev] wanted: CPU overhead source.

by Johannes Hofmann

Hi, I just profiled cvs- and 0.7.3 version. I used http://www.w3.org/TR/xslt20/ stored locally on disk (utilities.html rendered too fast here). I could not yet get any reproducible results from profiling, but cvs is obviously slower 5.1 vs. 3.9 seconds. And with cvs the GUI freezes until the whole page is loaded, whereas 0.7.3 displays the GUI while it is rendering the page (you can see the "Kb" counting in the upper right corner).

Thanks. Having said that on the basis of my gcc 2.95 based debian machine at home, I tried it on my work machine. The Redhat box actual uses: $ gcc -v Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release) *sigh* My attempts to read the auto<whatever> docs last week were very depressing, so I just looked at configure.in, and ponied up this fix: ========== --- dillo/configure.in Wed Dec 3 11:48:31 2003 +++ dillo_tweaked/configure.in Wed Dec 3 11:32:18 2003 @@ -201,7 +201,9 @@ if eval "test x$GCC = xyes"; then fi if test "`echo $CFLAGS | grep '\-W[^a]' 2> /dev/null`" = ""; then if test "`$CC -v 2>&1 | grep 'version 2'`" = ""; then - CFLAGS="$CFLAGS -W -Wno-unused-parameter" + if test "`$CC -v 2>&1 | grep 'version egcs-2'`" = ""; then + CFLAGS="$CFLAGS -W -Wno-unused-parameter" + fi fi fi if test "`echo $CFLAGS | grep '\-Waggregate-return' 2> /dev/null`" = ""; then ========== which simply adds anther test to exclude gcc 2.* based egcs releases before sticking in the new flags... Style question: Would it be better to test for the presence of the flag than to try to exclude those compilers without it? Anyway, thanks for the work. -- -- David McKee -- dmckee(a)jlab.org -- (757) 269-7492 (Office)
