I've been back from summer vacation for a couple of days.
|
||
|
|
My contract to work on git-annex has expired, at least for now,
|
||
|
|
but I have a lot of Patreon rewards to catch up on anyway. I've been
|
||
|
|
pushing hard for months on that contract and made a lot of progress on
|
||
|
|
long-term goals. Plan for the next little while is to cut back a little
|
||
|
|
bit, and work on easier stuff.
|
||
|
|
|
||
|
|
Today I improved how git-annex uses Copy-On-Write when copying between
|
||
|
|
two repositories on the same drive. It had relied on matching up device
|
||
|
|
numbers, but it turns out that with eg BTRFS subvolumes, CoW is supported
|
||
|
|
even when the device numbers don't match. Also, it was using cp even on
|
||
|
|
filesystems that don't support CoW, which prevented resuming after an
|
||
|
|
interruption. The new approach is to try to make a CoW copy once per remote,
|
||
|
|
and if it fails, fall back to rsync.
