Well well well....first of all...Happy New Year...2025.....a little bit late but anyhow, I'm alive and working...
A new version is somewhere around the corner.....I've spent the last days on doing some major rework on the rebuilder. Why? Well, it really performed lousy for "dats out of hell"....
For example, the progetto icons datfile which has 34000 icons where roughly 5000 are dupes....but running such a colleciton through the rebuilder means that it finds ~5000 matches for each of the ~5000 files....the rebuilder in clrmame wasn't well designed for that....and the memory footprint went up very high....and of course the rebuilding time.
The good thing is: The new implementation is way better. Plus it's also faster than the old one.
Just to give an impression: old cmpro rebuilder on the icons: 1m57s
clrmame rebuilder (while being fine on other stuff it totally failed here): not worth mentioning....I quit after an hour ;-)
reworked clrmame rebuilder for the next version: 1m42s
I have some minor stuff on my list before doing a release...but here's already a little sneak peak:
UI:
- added #thread selector
Core:
- misc: major rebuilder update / reworked internal logic, less complex, way smaller memory footprint especially for dats out of hell (dats with thousands of dupes), faster.
- misc: reimplementation of thread pools
- added: you can define a thread pool size which is used for parallel scanning rebuilding/etc. Either you keep auto (default value) or pick the number of threads used for the pool yourself. "auto" picks a high value when you work with compressed files and a low value when using decompressed ones. A low value is better when you run into file seek overhead issues. If you're not happy with auto, you can try to tweak it yourself.
- fixed: scanner and rebuilder ignore output path, mergemode, pattern changes when xml data hasn't changed
- fixed: scanner, accidently getting a crc32 on sub folders showing an error
- fixed: scanner, detection of unnneeded empty sub folders failed
- fixed: scanner, using old archive name when trying to remove some unneeded files causing can't remove files/can't access messages
- misc: updated bit7z to 4.0.9
- misc: use "-" instead of "_" for replacing illegal file chars (cmpro align)
- misc: monitoring hash folder for -listsoftware exports. In case of a change, cached data is ignored and a new export is generated. This is more for users which update their hash folders during the development phase of MAME on a regular basis and don't want to recompile the binary.
- misc: use one version number ;-)
