Summary: If a commit or update happens, check if the working copy is clean, and if it is, delete all the temporarily included files. This calls hg status, which may have perf implications, but since we're dealing with sparse checkouts, hopefully it won't be too bad for now. Test Plan: Ran the tests Reviewers: sid0, pyd, lcharignon, rmcelroy Reviewed By: rmcelroy Differential Revision: https://phabricator.fb.com/D1982949 Signature: t1:1982949:1428635990:29ddacdf3f32a38ce0e725ed9db7e13e98e0f21e

The sparse command is used to make the current checkout sparse.

Passing no arguments prints the currently applied sparse rules.
|

|
|
--include and --exclude are used to add and remove files from the sparse
|
|
checkout. The effects of adding an include or exclude rule are applied
|
|
immediately. If applying the new rule would cause a file with pending
|
|
changes to be added or removed, the command will fail. Pass --force to
|
|
force a rule change even with pending changes (the changes on disk will
|
|
be preserved).
|
|

--delete removes an existing include/exclude rule. The effects are

immediate.

|
--refresh refreshes the files on disk based on the sparse rules. This is
|
|
only necessary if .hg/sparse was changed by hand.
|
|
|
|
--enable-profile and --disable-profile accept a path to a .hgsparse file.
|
|
This allows defining sparse checkouts and tracking them inside the
|
|
repository. This is useful for defining commonly used sparse checkouts for
|
|
many people to use. As the profile definition changes over time, the sparse
|
|
checkout will automatically be updated appropriately, depending on which
|
|
commit is checked out. Changes to .hgsparse are not applied until they

have been committed.
