Summary:
This adds a --incremental flag to the hg repack command. This flag causes repack
to look at the distribution of pack files in the repo and performs the most
minimal repack to keep the repo in good shape. Currently it's only implemented
for datapacks.
The new remotefilelog.datagenerations config contains a list of the sizes for
the different generations of pack files. For instance:
[remotefilelog]
datagenerations=1GB
100MB
1MB
Designates 4 generations - packs over 1GB, packs over 100MB, packs over 1MB, and
implicitly packs undex 1MB. The incremental algorithm will try to keep each
generation to less than 3 pack files (prioritizing the larger generations
first). When performing a repack it will grab at least 2 packs, and will grab
more if the total pack size is less than 100MB (since repacking at that level is
pretty cheap).
I have no idea if this is a good algorithm. We'll how to see and iterate.
