[Partclone-user] partclone feature requests

Hello,


First, I have to thank for partclone, as it's vital component of my 
volunteer work.


Well, I have a couple of feature requests. Not sure how well 
sourceforge's tickets are cared for so I'm trying to send a mail.


#1 - Flush out the cache while restoring

When I am restoring to USB flash drive, there is a long long long pause 
between "99%" and "100%".

I am looking at the code and I can guess why. "fs_close()" is called 
after restoring and 100% shows up after fs_close() is done.

The machine with a lot of memory these days can hold a lot of dirty 
pages, and fs_close() forces the dirty cache to be flushed to USB flash 
drive, and this writing takes longer than actual restoring process.

For example, I restore 2.7GB disk image to a USB flash drive, last 
progress before 100 shows up at 44 seconds from the start.

100% progress shows up after 225 seconds.

That means, partclone is running but there is about 180 seconds of 
silence between <100 and 100% progress.

If there is a cache flush after each block is written to the device, the 
progress would be far more accurate.


Looking at the code, I can guess it's probably exfat_flush_nodes or 
exfat_flush does the job but I obviously don't have the knowledge.

If you want me to try something, I'm happy to.


#2 - Progress output format.

I'm parsing the output of partclone using Python. It would be great if 
the output is more machine readable.


Thanks and have a nice day.
