Merge branch 'vd/scalar-enables-fsmonitor'
"scalar" now enables built-in fsmonitor on enlisted repositories, when able. * vd/scalar-enables-fsmonitor: scalar: update technical doc roadmap with FSMonitor support scalar unregister: stop FSMonitor daemon scalar: enable built-in FSMonitor on `register` scalar: move config setting logic into its own function scalar-delete: do not 'die()' in 'delete_enlistment()' scalar-[un]register: clearly indicate source of error scalar-unregister: handle error codes greater than 0 scalar: constrain enlistment search

|

- `scalar-generalize-diagnose`: Move the functionality of `scalar diagnose`
|
||||
into `git diagnose` and `git bugreport --diagnose`.
|

|
||||
- 'scalar-add-fsmonitor: Enable the built-in FSMonitor in Scalar
|
||||
enlistments. At the end of this series, Scalar should be feature-complete
|

from the perspective of a user.
|
||||
|
||||
Roughly speaking (and subject to change), the following series are needed to
|
||||
"finish" this initial version of Scalar:
|
||||
|
||||
- Finish Scalar features: Enable the built-in FSMonitor in Scalar enlistments
|
||||
and implement `scalar help`. At the end of this series, Scalar should be
|
||||
feature-complete from the perspective of a user.
|
||||
|
||||
- Move Scalar to toplevel: Move Scalar out of `contrib/` and into the root of
|
||||
`git`, including updates to build and install it with the rest of Git. This
|
||||
change will incorporate Scalar into the Git CI and test framework, as well as
|
||||
expand regression and performance testing to ensure the tool is stable.
|
||||
`git`. This includes a variety of related updates, including:
|
||||
- building & installing Scalar in the Git root-level 'make [install]'.
|
||||
- builing & testing Scalar as part of CI.
|
||||
- moving and expanding test coverage of Scalar (including perf tests).
|
||||
- implementing 'scalar help'/'git help scalar' to display scalar
|
||||
documentation.
|
||||

Finally, there are two additional patch series that exist in Microsoft's fork of
|
||||
Git, but there is no current plan to upstream them. There are some interesting
