From: Zbigniew Jędrzejewski-Szmek Date: Thu, 4 Sep 2014 02:55:16 +0000 (-0400) Subject: localed: log locale/keymap changes in detail X-Git-Tag: v217~662 X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=502f961425f9dea1a85239766a3189695194da63 localed: log locale/keymap changes in detail Converting X11 to legacy keymaps and back is a fucking mess. Let's make it at least possible to request detailed logs of what is being changed and why (LOG_DEBUG level). At LOG_INFO level, we would log the requested change of X11 or console keymap, but not the resulting change after conversion to console or X11. Make sure that every change of configuration on disk has a matching line in the logs. --- diff --git a/src/locale/localed.c b/src/locale/localed.c index ac8477ad3..777da623f 100644 --- a/src/locale/localed.c +++ b/src/locale/localed.c @@ -265,10 +265,12 @@ static int context_read_data(Context *c) { return r < 0 ?
