[Vm-dev] Extending primitiveDirectoryEntry

[Alistair Grant]

Hi All,

I'm in the process of making FileReference>>moveTo: work across devices.
To make the implementation a bit cleaner on Linux it would be nice to
know whether the source and destination reside on the same disk
filesystem.  This can be determined by comparing stat.st_dev for the
source file and destination directory.

dir_EntryLookup() in sqUnixFile.c is exposed as primitiveDirectoryEntry
and used by FilePluginPrims>>lookupDirectory:filename:

It basically does a stat() on the supplied file and returns most of the
resulting information.  Unfortunately st_dev isn't returned.

Would there be any objection to me extending the Pharo version of
dir_EntryLookup() to include st_dev?

Thanks,
Alistair
