patch: binding to add bookmark
by corvid＠dillo.org Sept. 20, 2013

Sept. 20, 2013

Another simple one from the bug tracker. I don't use bookmarks heavily enough to have much need for this, but I can see that it could be convenient.

Not to worry I'll #ifdef my way around the variable length arrays, I guess I didn't look closely enough to realize that was what those were, thanks!

Proposed Patch for Zombies Left by Dpi_start_dpid() in dpi.c
by jgaffney＠lawrenceville.org Sept. 2, 2013

Sept. 2, 2013

It seems that the dpid children forked by Dpi_start_dpid() in dpi.c are not reaped when they terminate themselves after a period of inactivity while the parent dillo process is still running. The patch below is simply to reap these zombies. The SIGCHLD handler should probably do more, but I am not yet familiar enough with Dillo to know what. I believe this patch adheres to the Dillo rules of coding style, but am new to the list and a novice at Dillo patching. And hence also apologies to Jorge for this duplication of a previous communication by private email (although with one small change to get the patch to compile under OpenBSD as well as Linux). ######## BEGIN PATCH ######## --- a/src/IO/dpi.c 2013-01-27 12:26:38.000000000 -0500 +++ b/src/IO/dpi.c 2013-08-27 14:58:07.995235867 -0400 @@ -33,6 +33,8 @@ #include <netinet/tcp.h> #include <arpa/inet.h> #include <netdb.h> +#include <sys/wait.h> +#include <signal.h> #include "../msg.h" #include "../klist.h" @@ -331,16 +333,33 @@ } } +static void Sigchld_handler (int signum) { + int status; + waitpid (-1, &status, WNOHANG); + } + /* * Start dpid. * Return: 0 starting now, 1 Error. */ static int Dpi_start_dpid(void) { + static int install_sigchld_handler_flag = TRUE; pid_t pid; int st_pipe[2], ret = 1; char *answer; + if ( install_sigchld_handler_flag ) { + /* Install SIGCHLD handler. */ + struct sigaction sa; + sa.sa_handler = Sigchld_handler; + sigemptyset(&sa.sa_mask); + sa.sa_flags = SA_RESTART | SA_NOCLDSTOP; + if (sigaction(SIGCHLD, &sa, 0)) + MSG ("Unable to install SIGCHLD handler.\n"); + install_sigchld_handler_flag = FALSE; + } + /* create a pipe to track our child's status */ if (pipe(st_pipe)) return 1; ######## END PATCH ########

compilation error in fltkflatview.cc
by csoren＠isd.net Sept. 2, 2013

Sept. 2, 2013

Greets all, As I've mentioned previously I'm trying to compile dillo-3.0.3 on Silicon Graphics using the SGI MIPSpro compiler. I'm doing this for a large group of SGI users who reside at nekochan.net. The compilation fails in line 884 in fltkflatview.cc: ---------- cc-3168 CC: ERROR File = fltkui.cc, Line = 884 A name followed by "::" must be a class or namespace name. bool FltkToggleButtonResource<I>::FltkToggleButtonResource::isActivated () ^ cc-1443 CC: ERROR File = fltkui.cc, Line = 884 "dw::fltk::ui::FltkToggleButtonResource<I>::FltkToggleButtonResource" is not a class template. bool FltkToggleButtonResource<I>::FltkToggleButtonResource::isActivated () ^ 2 errors detected in the compilation of "fltkflatview.cc". ---------- I suspect it needs a 'using namespace' or somesuch here, thoughts? Thanks a bunch!

It works OK in Debian. [...] 1) OpenBSD is very strict about compliance with standards, so that, whereas on my (and I believe most if not all) Linux systems wait.h occurs redundantly in /usr/include/ and /usr/include/sys, on OpenBSD wait.h is solely in /usr/include/sys and your code will not compile unless the `#include<wait.h>' line is removed. Then `gcc -W -Wall' compiles it without complaint. 2) OpenSBD is not so extravagant with the resources allocated to unprivileged users (max 128 processes). But spawning 64 rather than 256 children the test is passed with the expected behavior on OpenBSD 5.2 GENERIC.MP#368 amd64. The OpenBSD 5.2 ports include Dillo 2.2 and FLTK2, but I just recently compiled FLTK 1.3.2 and Dillo 3.0.3 from their unmodified source on that machine without (IIRC) any errors. If you were curious more generally to see how they are modifying the Dillo source, the OpenBSD patches for Dillo 3.0.3 (the version currently in ports for OpenBSD 5.3) may be found at http://www.openbsd.org/cgi-bin/cvsweb/ports/www/dillo/patches/
