Dear Philip,
The suggestion by Akira-san resolves the problem :
It seems that I was wrong:
By experiments, I found that the renaming,
cachefile.NEW --> cachefile, almost always
fails if executed from the XeTeX binary even
in a user's writable directory.
Thus if you find a delay of time, run
fc-cache -v.
If messages
invalid cache file: ...
are shown, run
fc-cache -v
once more.
--- related function ---
FcBool
FcAtomicReplaceOrig (FcAtomic *atomic)
{
#ifdef _WIN32
unlink ((const char *) atomic->file);
/* fails always if executed from the XeTeX binary */
#endif
if (rename ((char *) atomic->new, (char *) atomic->file) < 0)
return FcFalse;
return FcTrue;
}
Best,
Akira
