Description Matthias Clasen 2005-03-24 22:30:51 UTC 
As things are currently, each app mallocs around 50k for the mime data. 
To make things worse, gtk and gnome-vfs have their own copies of the data.
We propose to define a binary cache format (in addition to the text files
which are currently created), and allow apps to mmap that.

I'll attach a proposal for such a cache format, and a patch which makes
update-mime-database generate these files.

combined patch

The new patch is unchanged for update-mime-database.c
It patches the description of the cache file format into the spec 
now.
