Bug 626748 – Use async methods for writing and handle EAGAIN If sending a lot of data and/or the other peer is not reading it, then socket buffers can overflow. This is communicated from the kernel by returning EAGAIN. In GIO, it is modelled by g_output_stream_write() and g_socket_send_message() returning G_IO_ERROR_WOULD_BLOCK. It is also problematic that that we're using synchronous IO in the shared GDBus IO thread. It means that one GDBusConnection can lock up others. It turns out that by porting from g_output_stream_write() to g_output_stream_write_async() we fix the EAGAIN issue. For GSocket, we still need to handle things manually (by creating a GSource) as g_socket_send_message() is used. We check the new behavior in Michael's producer/consumer test case (at /gdbus/overflow in gdbus-peer.c) added in the last commit. Also add a test case that sends and receives a 20 MiB message. Also add a new `transport' G_DBUS_DEBUG option so it is easy to inspect partial writes: $ G_DBUS_DEBUG=transport ./gdbus-connection -p /gdbus/connection/large_message [...] ======================================================================== GDBus-debug:Transport: >>>> WROTE 128000 bytes of message with serial 4 and size 20971669 from offset 0 on a GSocketOutputStream ======================================================================== GDBus-debug:Transport: >>>> WROTE 128000 bytes of message with serial 4 and size 20971669 from offset 128000 on a GSocketOutputStream ======================================================================== GDBus-debug:Transport: >>>> WROTE 128000 bytes of message with serial 4 and size 20971669 from offset 256000 on a GSocketOutputStream [...] ======================================================================== GDBus-debug:Transport: >>>> WROTE 43669 bytes of message with serial 4 and size 20971669 from offset 20928000 on a GSocketOutputStream [...] ======================================================================== GDBus-debug:Transport: <<<< READ 16 bytes of message with serial 3 and size 20971620 to offset 0 from a GSocketInputStream ======================================================================== GDBus-debug:Transport: <<<< READ 15984 bytes of message with serial 3 and size 20971620 to offset 16 from a GSocketInputStream ======================================================================== GDBus-debug:Transport: <<<< READ 16000 bytes of message with serial 3 and size 20971620 to offset 16000 from a GSocketInputStream [...] ======================================================================== GDBus-debug:Transport: <<<< READ 144000 bytes of message with serial 3 and size 20971620 to offset 20720000 from a GSocketInputStream ======================================================================== GDBus-debug:Transport: <<<< READ 107620 bytes of message with serial 3 and size 20971620 to offset 20864000 from a GSocketInputStream OK https://bugzilla.gnome.org/show_bug.cgi?id=626748 Signed-off-by: David Zeuthen <davidz@redhat.com>

GDBusMessage: Fix bug when deserializing a message See https://bugzilla.gnome.org/show_bug.cgi?id=621838 for the whole story. The problem was that we ended up reading data from arrays of arrays when we were just supposed to be aligning the buffers. Also add a host of debug infrastructure that was needed to find the root cause. For now it can be turned on only via defining DEBUG_SERIALIZER. In the future we might want to make it work via G_DBUS_DEBUG. In a nutshell, the added debug info looks like this Parsing blob (blob_len = 0x0084 bytes) 0000: 6c 01 00 01 3c 00 00 00 41 00 00 00 37 00 00 00 l...<...A...7... 0010: 08 01 67 00 08 61 61 79 61 7b 73 76 7d 00 00 00 ..g..aaya{sv}... 0020: 01 01 6f 00 08 00 00 00 2f 66 6f 6f 2f 62 61 72 ..o...../foo/bar 0030: 00 00 00 00 00 00 00 00 03 01 73 00 06 00 00 00 ..........s..... 0040: 4d 65 6d 62 65 72 00 00 00 00 00 00 34 00 00 00 Member......4... 0050: 03 00 00 00 63 77 64 00 01 73 00 00 23 00 00 00 ....cwd..s..#... 0060: 2f 68 6f 6d 65 2f 64 61 76 69 64 7a 2f 48 61 63 /home/davidz/Hac 0070: 6b 69 6e 67 2f 67 6c 69 62 2f 67 69 6f 2f 74 65 king/glib/gio/te 0080: 73 74 73 00 sts.

gdbus, win32: autolaunch bus with gdbus.exe instead of rundll32 This is a bit of breaking change: After this commit the apps relying of win32 dbus autolaunching, need to install gdbus.exe alongside with libgio-2.0-0.dll. A new command for gdbus tool is used for running server: gdbus.exe _win32_run_session_bus To implement it gdbus.exe uses the same exported function g_win32_run_session_bus that earlier was used by rundll. So (private) ABI was not changed. It runs the bus syncronously, exiting after inactivity timeout - all exactly like it was runed earlier with the help of rundll32. While private exported function may have _some_ version compatibility issues between gdbus.exe and libgio-2.0-0.dll compiling dbus server registration logic directly into gdbus.exe can lead to _more hidden and more complex_ compatibility issues since the names and behaviour of syncronization objects used to publish server address would be required compatible between gdbus.exe and libgio-2.0-0.dll. So using "private" exported function to call looks like more safe behaviour. gdbus.exe binary was selected for this task since it has corresponding name and at least for msys2 is shippied in same package with libgio-2.0-0.dll turn_off_the_starting_cursor function is also kept as is, however it is not obvious if it is still needed (by now I failed reproducing original issue). Explicit g_warnings added to help with possible problematic cases for absent or incompatible gdbus.exe Mainloop is created after successful daemon creation Before this change the function leaked mainloop on daemon creation fail

This can be suboptimal or even totally broken, depending on the app and what it tries to do. [...] You can always avoid autolaunch by manually setting DBUS_SESSION_BUS_ADDRESS. Autolaunch happens because the default address if none is set is "autolaunch:", so if any other address is set there will be no autolaunch. You can however include autolaunch in an explicit session bus address as a fallback, for example DBUS_SESSION_BUS_ADDRESS="something:,autolaunch:" - in that case if the first address doesn't work, processes will autolaunch. (The bus address variable contains a comma-separated list of addresses to try.) Signed-off-by: David Zeuthen <davidz@redhat.com>
