13:31:46 <dminuoso> freerdp crashes when opening .rdp files with the following error: https://gist.github.com/dminuoso/855e233956248052108e8e2ce30719be
13:31:56 <dminuoso> How can I figure out what freerdp is trying to do?
14:01:16 <liskin> dminuoso: maybe ltrace can be asked to print the source location of the library calls
14:02:01 <liskin> If not then I guess you can set a breakpoint to the Xlib error handler in gdb and then print the backtrace
14:33:11 × geekosaur quits (~geekosaur@xmonad/geekosaur) (Remote host closed the connection)

14:52:36 <sfrique[m]> sometimes it cuts the windows size, sometimes the windows kind of "gravitates" to a corner and stick there

20:06:02 → Kobold joins (~koboldchi@12.18.150.83)
20:13:34 → mc47 joins (~mc47@xmonad/TheMC47)
20:14:27 <mc47> liskin I'd be happy to help with some of the tedious paperwor if it comes to that
20:15:28 <mc47> it would be cool to have a financial incentive for (some of) the maintainers, as like you said, the project needs maintenance
20:16:35 <mc47> (I just managed to read the logs, I haven't been spending much time in front of the screen)
20:27:13 → themc47 joins (~mc47@xmonad/TheMC47)
20:27:54 <dminuoso> liskin: Mmm I give up.
20:27:59 <dminuoso> RDP is awful. :(
20:28:52 <dminuoso> freerdp misbehaves in strange ways. it holds permanent keyboard grabs..
20:29:19 <dminuoso> Which is *not* a fun thing in an environment when you dont have window decorations to kill a window
20:29:50 × mc47 quits (~mc47@xmonad/TheMC47) (Ping timeout: 265 seconds)
20:32:39 → mc47 joins (~mc47@xmonad/TheMC47)
20:33:44 <sfrique[m]> dminuoso: have you tried `-grab-keyboard off` ?
20:34:06 × themc47 quits (~mc47@xmonad/TheMC47) (Ping timeout: 252 seconds)
20:41:22 <dminuoso> sfrique[m]: ah mmm, I did not notice
20:42:00 × Kobold quits (~koboldchi@12.18.150.83) (Quit: Leaving)
21:05:55 <liskin> dminuoso: might be a good idea to have one of the layout with decorations then :-)
21:06:23 <dminuoso> Mmm, cant quite make it out where it goes haywire, it seems that x fails at XSync
21:06:46 <dminuoso> Is it correct that x property changes get queued up and flushed on XSync?
21:09:44 <liskin> mc47: actually I don't think there will be too much paperwork (that's the whole point of having a fiscal sponsor as opposed to having our own legal entity), but there may be some stuff that can only be done by people who can in some way prove their affiliation to the project (like admins of github org, but maybe possibly some copyrights, I don't know), and there also may be some stuff that can only
21:09:47 <liskin> be done by US citizens (like setting up github sponsors for the org)
21:10:47 × mc47 quits (~mc47@xmonad/TheMC47) (Ping timeout: 258 seconds)
21:12:08 <liskin> it's quite likely it can all be done in a day if we have all that's needed, it's just that I have no idea what is needed :-)
21:12:09 → mc47 joins (~mc47@xmonad/TheMC47)
21:12:45 <liskin> once we agree that we want to try it we can just do it and see :-)
21:13:21 <liskin> dminuoso: I have no idea about xsync and prop changes; last time I needed to know something like this I just googled and maybe looked it up in xlib sources
21:15:04 <geekosaur> most things queue up for XSync calls, I think
21:16:48 <dminuoso> Well I have pinpointed it down
21:17:21 <dminuoso> XChangeProperty(xfc->display, appWindow->handle, xfc->_NET_WM_WINDOW_TYPE, XA_ATOM, 32, PropModeReplace, (BYTE*)&window_type, 1);
21:17:39 × seschwar quits (~seschwar@user/seschwar) (Quit: :wq)
21:18:15 <dminuoso> https://github.com/FreeRDP/FreeRDP/blob/master/client/X11/xf_window.c#L658-L661
21:18:23 <dminuoso> With this atom mmm
21:20:06 × mc47 quits (~mc47@xmonad/TheMC47) (Ping timeout: 265 seconds)
21:22:17 <liskin> "Atom id in failed request: 0x0" - do we trust this or not?
21:23:26 <dminuoso> oh heh
21:24:03 <dminuoso> liskin: I wouldnt
21:24:17 <dminuoso> Im `p`ing in gdb, and Im seeing different values here
21:24:28 <dminuoso> Although huh
21:24:30 <dminuoso> What the heck
21:24:35 <dminuoso> (gdb) p window_type
21:24:37 <dminuoso> $4 = 0
21:27:05 <liskin> that's weird, all the if branches set a value
21:27:19 <liskin> perhaps xfc is uninitialized?
21:27:35 <liskin> (I'm assuming XInternAtom can't really return a zero normally, can it?)
21:27:58 <dminuoso> nah, if xfc was uninitialized everything would be crashing left and right
21:37:26 <liskin> yeah, so what do you get if you p all the xfc->_NET_WM_WINDOW_TYPE_DROPDOWN_MENU, xfc->_NET_WM_WINDOW_TYPE_NORMAL, xfc->_NET_WM_WINDOW_TYPE_DIALOG ?
21:37:38 <dminuoso> liskin: Ah I just suck at nix it seems
21:37:57 <liskin> :-D
21:38:14 <dminuoso> nix-shell -p '(pkgs.enableDebugging pkgs.freerdp)'
21:38:18 <dminuoso> Does not do what I think it does
21:38:24 <dminuoso> Bleerg
21:39:05 liskin still knows nothing about nix and after this zurihac, I have even less motivation to learn anything about it then before :-)
21:39:40 <dminuoso> heh, I learned much new stuff today about nixos modules
21:39:58 <dminuoso> its a bit disgusting that you kind of have to understand all the internals in order to not be surprised left and right
21:40:34 <liskin> that's probably true of xmonad too :-)
21:40:57 <geekosaur> true, but a lot less to be understood than of nix
21:40:57 <dminuoso> window_type
21:41:01 <dminuoso> $1 = 393
21:41:40 <dminuoso> geekosaur: with xmonad you can just use whatever is in contrib and never worry about all the X quirks
21:41:51 <dminuoso> You'll probably survive, until you want to use freerdp..
21:41:53 <dminuoso> :-P
21:41:57 <liskin> okay fair enough
21:42:25 <liskin> anyway, window_type=393, but you sure that's the one it crashes with?
21:43:52 <dminuoso> Im not sure of anything, this is still an optimized build..
21:46:08 <liskin> oh
21:46:39 <geekosaur> "If only_if_exists is False, the atom is created if it does not exist. Therefore, XInternAtom() can return None."
21:47:10 <liskin> back when I used to do these things, reading the asm was a good way to tell what the real value might be
21:47:22 <liskin> but gdb would usually tell you if it wasn't sure
21:47:51 <liskin> https://github.com/FreeRDP/FreeRDP/blob/670cf8512ba751054b0e09d5c41e890953fbbb62/client/X11/xf_client.c#L1915
21:48:08 <liskin> only_if_exists seems to be FALSE, so it should be fine
21:53:46 <liskin> heading to bed, good look with the rest of the debugging, good night :-)
21:54:24 <dminuoso> liskin: thanks!
21:54:31 <dminuoso> Found it
21:54:33 <dminuoso> It was something else
21:54:41 <dminuoso> xf_SetWindowUnlisted(xfc, appWindow->handle);
21:55:00 <dminuoso> If I XSync right before it, everything is fine, XSync after and I get the BadAtom error
21:55:12 <dminuoso> Oh
21:57:40 <dminuoso> That function is optimized away :(
21:59:29 <dminuoso> geekosaur: Thank you too.
21:59:32 <dminuoso> I think I figured it out
22:35:20 <dminuoso> If I read this right, this is a weird memory bug. Should _NET_WM_STATE ever be XA_ATOM?
22:36:21 <dminuoso> https://specifications.freedesktop.org/wm-spec/wm-spec-1.3.html
22:36:28 <dminuoso> This suggests it should be an atom list
22:44:25 <geekosaur> there's no difference between a singular value and a list of length 1
22:45:54 <geekosaur> https://tronche.com/gui/x/xlib/window-information/obtain-properties.html
22:46:11 <dminuoso> geekosaur: https://github.com/FreeRDP/FreeRDP/blob/670cf8512ba751054b0e09d5c41e890953fbbb62/client/X11/xf_window.c#L430-L431
22:47:22 <dminuoso> Shouldn't that be a None terminated list?
22:47:42 × kajzer quits (~themainma@user/themainman) (Quit: WeeChat 3.1)
22:48:09 <geekosaur> no, there's a length parameter instead
22:48:44 <geekosaur> it's the 2 following the pointer to the values
22:49:38 <dminuoso> Then its completely beyond me. It's specifically that call that generates the BadAtom.
22:49:48 <dminuoso> I managed to narrow it down in an unoptimized build properly
22:54:23 <geekosaur> you can see from all the non-array ones that just use a pointer to the value and a length of 1, things would have exploded well before then if it weren't length delimited
22:54:50 <geekosaur> so I'd check what the atoms are there if possible
22:57:41 <geekosaur> in particular I could see both those atoms not existing if you aren't running a taskbar or pager, so the app would have to create them (!only_if_exists, but I think liskin verified that?)
22:57:41 × geekosaur quits (~geekosaur@xmonad/geekosaur) (Remote host closed the connection)
22:59:58 → geekosaur joins (~geekosaur@xmonad/geekosaur)
23:01:30 <geekosaur> yeh, they're all False (except the one that's FALSE but it's not one of these)
23:01:39 <dminuoso> Ive double checked, they all exist
23:04:17 <geekosaur> aha
23:05:24 <geekosaur> they all exist but _NET_WM_STATE is wrapped by get_supported_atom() which checks if it's in _NET_SUPPORTED and returns None if not, and I am pretty sure we don't advertise that one because xmonad itself doesn't care
23:07:50 <geekosaur> confirmed on my own desktop, we don't advertise _NET_WM_STATE
23:07:52 <dminuoso> (gdb) p xfc->_NET_WM_STATE
23:07:54 <dminuoso> $13 = 0
23:07:56 <dminuoso> Ahhh
23:08:13 <dminuoso> Does xmonad have some hook to advertise this?
23:08:37 <geekosaur> I'm not sure where we currently are on that, there's some stuff in flight for extensible EWMH hooks
23:08:43 <dminuoso> https://hackage.haskell.org/package/xmonad-contrib-0.16/docs/src/XMonad.Hooks.EwmhDesktops.html#setSupported
23:08:45 <dminuoso> Indeed
23:08:49 <geekosaur> which the current iteration of fullscreen windows should use
23:09:06 <dminuoso> Perhaps _NET_WM_STATE even belongs in there
23:09:46 <dminuoso> Though its still a freerdp bug that it checks for supported, and completely ignores the response it gets..
