Subject: Port to glib 2.31.x g_thread API
X-Git-Tag: dbus-1.4.20~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=19343fb6a8a4bd3a2008c07b4f13ee2b0bf700d7;p=thirdparty%2Fdbus.git

Port to glib 2.31.x g_thread API

g_thread_init() is deprecated since glib 2.24, call g_type_init() instead.
Bump glib requirement accordingly.

g_thread_create is deprecated since 2.31, use g_thread_new() instead. When
building with a glib earlier than 2.31, provide a backwards compatibility shim.

[Added a comment about why we're using g_type_init() in a test that
doesn't otherwise use GObject -smcv]

[Applied to 1.4 despite just being a deprecation fix because it also fixes
linking with GLib 2.32, in which gthread has been removed from gobject's
Requires and moved to Requires.private, Debian #665665 -smcv]
