There's no need to do this and not doing so speeds up IMM tremendously when the sparse profile had to be adjusted. (This is the grafted version from the fb-hgext repo) Test Plan: I ran an IMM before and after this change. Both succeeded but the later version was much faster.

"""make the current checkout sparse, or edit the existing checkout
|
|
|
|
The sparse command is used to make the current checkout sparse.
|
|
This means files that don't meet the sparse condition will not be
|
|
written to disk, or show up in any working copy operations. It does
|
|
not affect files in history in any way.
|
|
|
|
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
|
|
changeset is checked out. Changes to .hgsparse are not applied until they
|
|
have been committed.
|
|
|
|
--import-rules accepts a path to a file containing rules in the .hgsparse
|
|
format, allowing you to add --include, --exclude and --enable-profile rules
|
|
in bulk. Like the --include, --exclude and --enable-profile switches, the
|
|
changes are applied immediately.
|
|
|
|
--clear-rules removes all local include and exclude rules, while leaving
|
|
any enabled profiles in place.
|
|
|
|
--cwd-list list all the contents of the current directory. The files that
|
|
are excluded by the current sparse checkout are annotated with a hyphen
|
|
('-') before the name.
|
|
|
|
--list-profiles lists all available profiles, indicating which ones are
|
|
currently active. Activated profiles are marked with a `*`, profiles
|
|
included transitively are marked with a ~.
|
|
|
|
The following config option defines whether sparse treats supplied
|
|
paths as relative to repo root or to the current working dir for
|
|
include and exclude options:
|
|
|
|
[sparse]
|
|
includereporootpaths = off
|

The following config option defines whether sparse treats supplied

enableprofile and disableprofile options:

|
|
enablereporootpaths = on
|
|
|
|
You can configure a path to find sparse profiles in; this path is

used to discover available sparse profiles. Nested directories are
|

reflected in the UI.
