Hi,
Recently I found that format of fonts.cache-2 file are different on
32bit and 64bit system. It leads big performance issue for 32bit
applications on 32bit/64bit mixed system, like x86_64. Because 32bit
applications must re-create local cache file on startup, almost every
time.
For more information, see https://bugzilla.novell.com/show_bug.cgi?id=160226
Is it possible to unify the cache file format for both 32bit and
64bit system?
That bug is not world readable.
I designed the cache format so that it would contain caches for both
32bit and 64bit systems in the same file. It may not work; I'll look
into it tomorrow.
I think I have fixed it, see also
http://bugzilla.novell.com/show_bug.cgi?id=160226
fc-cache32 would be a fine solution to the dir caches problem, if you
can generate that binary.
Your patch makes things better but doesn't completely fix the problem
yet. I'm looking into it.
The system I'm on here is amd64 with an ia32 chroot. /home is shared
between the amd64 install and the chroot.
1. remove a fonts.cache-2 file (dir cache) from both the install and the
chroot
2. fc-list in the install
3. fc-list in the chroot
4. fc-cat ~/.fonts.cache-2 in the install
You'll see that the install's .fonts.cache-2 gets trampled by the
chroot's .fonts.cache-2.
Note also that the line you patched was a fix to 'severe perf regression
when global fonts.cache-2 files are missing', which you and I tested
back in October 2005. I'm going to test that behaviour as well (put
junk in .fonts.cache-2, see what happens).
