How about this for a concrete proposal (with intent on landing some bits of
sparse in 4.3):
1) Drop a copy of Facebook's sparse.py into hgext/ along with
minimally-modified tests
2) Mark extension as experimental and not subject to any BC guarantees
3) Rename "sparse" command to "debugsparse" until we have a proper UX bikeshed
4) Start moving code from extension into core where appropriate. This will help
flush out what considerations core needs to make for maintaining sparse
checkouts
5) Attempt to stabilize the sparse profiles file format so daring consumers can
use sparse checkouts in 4.3 without major BC concerns from file formats
6) Bikeshed and paint the shed
7) Repeat #6
8) (a few releases later) drop experimental labeling and/or move sparse checkout into
core as a feature that is enabled by default (presumably this is gated on a
"sign-off" from narrow clone)
This works for me, assuming it's okay for the Facebook end of things. I don't
want to hurt them while we're getting this sorted.
Sounds good. My only request would be that if any breaking changes are made,
please include Facebook in the discussion so we can plan ahead for the
breakage (since this is all already in production here).
That sounds eminently reasonable. Do you have any usability gripes
from users today that we should put in the backlog of things to
change?
Most people don't have any issues, since most people don't run any
sparse commands (since a profile is set up for them when they clone).
Certain power users do wish it was easier to pull in more changes. For
instance, it might be nice if instead of running 'cd path/to/foo' a user
could run 'hg cd path/to/foo' and it would material that directory and
take you there. That's somewhat orthogonal to the existing ui and
implementation though.
Better man page style documentation around sparse profiles could be
useful as well.
