Vladimir Sementsov-Ogievskiy 8cb17f9c36 util: drop qemu_socket_set_nonblock() Use common qemu_set_blocking() instead. Note that pre-patch the behavior of Win32 and Linux realizations are inconsistent: we ignore failure for Win32, and assert success for Linux. How do we convert the callers? 1. Most of callers call qemu_socket_set_nonblock() on a freshly created socket fd, in conditions when we may simply report an error. Seems correct switching to error handling both for Windows (pre-patch error is ignored) and Linux (pre-patch we assert success). Anyway, we normally don't expect errors in these cases. Still in tests let's use &error_abort for simplicity. What are exclusions? 2. hw/virtio/vhost-user.c - we are inside #ifdef CONFIG_LINUX, so no damage in switching to error handling from assertion. 3. io/channel-socket.c: here we convert both old calls to qemu_socket_set_nonblock() and qemu_socket_set_block() to one new call. Pre-patch we assert success for Linux in qemu_socket_set_nonblock(), and ignore all other errors here. So, for Windows switch is a bit dangerous: we may get new errors or crashes(when error_abort is passed) in cases where we have silently ignored the error before (was it correct in all such cases, if they were?) Still, there is no other way to stricter API than take this risk. 4. util/vhost-user-server - compiled only for Linux (see util/meson.build), so we are safe, switching from assertion to &error_abort. Note: In qga/channel-posix.c we use g_warning(), where g_printerr() would actually be a better choice. Still let's for now follow common style of qga, where g_warning() is commonly used to print such messages, and no call to g_printerr(). Converting everything to use g_printerr() should better be another series. Reviewed-by: Daniel P.
