Attached is the current version of my little experiments. The main
changes are:
- I switched to adler32 instead of md5sum
- I added a little index database implementation, rpmidx.[ch]
The index database is using mmap to map the database into memory.
It uses the main rpmpkg database for locking.
Performance and database sizes seem to be promising.
Things I'm not happy about:
- resizing currently works by rebuilding a new database and
calling rename(). I can change this to be inplace, though,
it just makes to code a little bit slower because I don't
want to simply overwrite the old data. I basically want an
"atomic" switch to the new data.
- The generation count in idxdb is currently not used. My goal
is to detect crashed database updates somehow.
Cheers,
Michael.
