# These suppressions address data races and deadlock warnings in external
# libraries that cannot be fixed in KiCad code.

# GLib/GIO internal races
# GLib's DBus implementation and memory allocation have known threading issues
# that are reported by TSan but are considered benign by the GLib maintainers.

# Pango/Fontconfig font caching races
# Pango spawns background threads for font discovery that race with the main
# thread during font caching operations. These are internal to pango/fontconfig.

# GObject type system lock ordering
# The GObject type system initialization can trigger lock order warnings
# that are internal to glib's type registration mechanism. These occur during
# KiCad startup when KICAD_MANAGER_FRAME is created and gio is initialized.
