Bug #68877 for Gtk2: FileChooser

Thu Jun 16 15:50:16 2011 peter [...] vereshagin.org - Ticket created

Subject:

FileChooser

trying v1.223 from freebsd ports. Test GtkFileChooser.t skips itself because it's unstable, are there any details about that? Every other t/GtkFileChooser*.t hangs forever after telling '1..N' Same goes with examples/file_chooser.pl But not about examples/filesel_multisel.pl What's the difference? Should I need to have some Gnome helpers daemons like dbus, hal, etc. ? At least I use gam_server from devel/gamin port instead of SGI's fam daemon. It looks very much like waiting for some daemon to respond. gtk-2.22.1_1 and perl-5.14.0 Thank you.

Well, the file chooser is hard to test, so the test results were unreliable. Show quoted text

GtkFileChooser is a modern and completely independent version of GtkFileSelection. It might be that some daemon is being waited for, but it might also be related to threading issues -- we've seen multiple reports of hangs on FreeBSD related to threading: <http://mail.gnome.org/archives/gtk-perl-list/2011-November/msg00038.html>, for example. Please try the attached programs. Does the Perl program hang for you? Does the C program hang as well? Compile with gcc `pkg-config --libs --cflags gtk+-2.0` gtk-file-chooser-test.c -o gtk-file-chooser-test

ok I think I should try with newer FreeBSD some day. Show quoted text

C program works just fine. Every other gtk2 program on a machine can open/save files with this dialog, I try 'asciio' as the only perl-gtk program yet and can't open/save from there. Think I should request a 'current file name' command-line argument feature for App::Asciio. Or implement it myself first.

Sorry I forgot to note: - I upgraded the p5-Gtk2 port to 1.242 and this required to upgrade the p5-Glib2 to p5-Glib2-1.250_1 and several other ports, too, according to the latest ports tree. - I use X11 via TCP from jail(4) environment as xorg-server requires chroot, not jail. x11 server is in the separate chroot. FileChooser behaves the same after upgrade mentioned.

Sorry to chime in, but what version of freebsd was that? Especially older versions had a very low-quality pthreads implementation (malloc wasn't threadsafe for example), and even current versions do not support pthreads enough to make perl work in all cases (calling malloc after fork is not supported for example). perl puts a lot of requirements on pthreads that are not guaranteed by POSIX, but are implemented on e.g. GNU/Linux, causing weird problems on various bsds which limit themselves to a subset of posix. The failures could be caused by something "simple", such as: - using the perl malloc replacement (which relies on sbrk which is not threadsafe on freebsd last I looked, but maybe is nowadays). - a general incompatibility, because old freebsd versions had basically non- working threads (e.g. freebsd 6, freebsd 7 is much better) - having perl not compiled with threads, but linking gtk against threads, which also doesn't work in older versions of freebsd - the main program has to be linked with -pthread. - using -lpthread instead of -pthread. -- The choice of a Deliantra, the free code+content MORPG -----==- _GNU_ http://www.deliantra.net ----==-- _ generation ---==---(_)__ __ ____ __ Marc Lehmann --==---/ / _ \/ // /\ \/ / schmorp@schmorp.de -=====/_/_//_/\_,_/ /_/\_\

We now have lots of evidence that hints at these tests requiring perl be linked with "-pthread" since they use threads under the hood, just as Marc hinted at. So, please try again with this commit: <https://git.gnome.org/browse/perl-Gtk2/commit/?id=4128c861e6650a64b5cf1830248357fb7e9c3284>.
