flash-plugin-11.2.202.233 and nspluginwrapper keep crashing under Fedora 16

[ydroneaud]

FlashPlayer pluging keep crashing for one or two week.

I'm getting those messages in .xsession-error

Gdk-ERROR *: The program 'npviewer.bin' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 8415 error_code 8 request_code 140 minor_code 3) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) ** NSPlugin Wrapper *** ERROR: NPP_HandleEvent() wait for reply: Connection closed *** NSPlugin Wrapper *** WARNING:(../src/npw-wrapper.c:2219):invoke_NPP_SetWindow: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(../src/npw-wrapper.c:2848):invoke_NPP_HandleEvent: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(../src/npw-wrapper.c:2655):invoke_NPP_WriteReady: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(../src/npw-wrapper.c:2705):invoke_NPP_Write: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(../src/npw-wrapper.c:2550):invoke_NPP_DestroyStream: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(../src/npw-wrapper.c:2434):invoke_NPP_URLNotify: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(../src/npw-wrapper.c:2848):invoke_NPP_HandleEvent: assertion failed: (rpc_method_invoke_possible(plugin->connection))

When ran under ElectricFence, EF complains about:

When ran with

NPW_DEBUG=1 NPW_LOG=nspluginwrapper.log firefox

nspluginwrapper crash almost immediately ... in a meaningless spot. See bug 819448

[ydroneaud]

When removing NPW_LOG= argument, it's working better.

You will find in gist 2627119 two debug logs, one without valgrind, the the other one with valgrind enabled with NPW_USE_VALGRIND=yes (I have also modified npviewer.sh to add --sync to npviewer.bin arguments).

In the valgrind log, you could find this trace:

Gdk-ERROR **: The program 'npviewer.bin' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 1137 error_code 8 request_code 140 minor_code 3) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) ==18893== ==18893== Process terminating with default action of signal 5 (SIGTRAP) ==18893== at 0x39EE44D783: g_logv (gmessages.c:577) ==18893== by 0x39EE44DB11: g_log (gmessages.c:591) ==18893== by 0x39F1A6AB2A: gdk_x_error (gdkmain-x11.c:486) ==18893== by 0x3138A4810E: _XError (XlibInt.c:1583) ==18893== by 0x3138A44F90: handle_error (xcb_io.c:166) ==18893== by 0x3138A44FD4: handle_response (xcb_io.c:266) ==18893== by 0x3138A45DDF: _XReply (xcb_io.c:566) ==18893== by 0x3138A415A2: XSync (Sync.c:44) ==18893== by 0x3138A4164A: _XSyncFunction (Synchro.c:35) ==18893== by 0x3139209AA9: XShmPutImage (XShm.c:352) ==18893== by 0x39F1A5C40D: gdk_x11_draw_image (gdkdrawable-x11.c:847) ==18893== by 0x564B2F7: ???

So this might not be something nspluginwrapper could fix ...

Wow. Thank you for the incredibly detailed report. I'll see if I can figure it out sometime (it's the end of term, so I'm a little busy these days).

A quick question: It seems from the first log that you're running everything under nspluginwrapper, including even libgnome-shell-browser-plugin.so and libvlcplugin.so. Do you actually need nspluginwrapper? If you're running x86-64, Adobe has an official 64-bit plugin now (in fact you may even be using it... your flash is installed in /usr/lib64). If you don't actually need it, I'd recommend just running the plugins without nspluginwrapper. You don't gain anything in the way of sandboxing, Firefox and Chrome natively push plugins out-of-process, and nspluginwrapper is, and, as you may have noticed, pretty buggy. I'm not sure how Fedora sets it up, but just uninstalling it would probably work.

(I have to admit: I myself have stopped using it for anything since Adobe put out a 64-bit Flash.)

The configuration was working for a while. I can't find what has changed in the past two weeks to break Flash player and/or nspluginwrapper. I was in trouble to figure myself what's happening. And found nothing matching my problem on the Internet.

Regarding wrapper under Fedora, I think it's the default configuration.

Don't spend to much time investigating. If I'm the sole user with this problem, it could be hardware related ... but it would be very nasty.

Regarding wrapper under Fedora, I think it's the default configuration.

I strongly recommend against doing that. There's really no benefit to running nspluginwrapper when both the plugin and the browser are the same architecture. You only expose yourself to more bugs. Because of how NPAPI is set up (it's completely synchronous and relies on the run-to-completion semantics you get from this), you actually can't do a good job of pushing the plugin out-of-process to protect from things like a stuck plugin in something like nspluginwrapper. Firefox and Chrome can (and already do) implement this better because they only need to speak NPAPI on one side. (They could also do a better compatibility layer for running 32-bit plugins but don't.)

In fact, if you are running Chrome, it will detect wrapper plugins of matching architecture and go straight to the original plugin because nspluginwrapper was the source of many crashes. I managed to fix some of them when I adopted the project, but I'm not surprised there are still problems.

Here's my plugin config output. See that flashplayer is reported twice. I have checked it against another Fedora 16 system which report the same thing.
