fix/lfs.customtransfer.drs.*

[bwalsh]

Proposal: Namespace all git-drs configuration under lfs.customtransfer.drs.*

Summary

Standardize all git-drs configuration so that every config key is namespaced under:

lfs.customtransfer.drs.*

This aligns git-drs with Git LFS custom transfer conventions, avoids global namespace pollution, and makes configuration intent unambiguous.

---

Current State

The current configuration mixes LFS-scoped keys with global drs.* keys:

lfs.standalonetransferagent=drs
lfs.customtransfer.drs.path=git-drs
lfs.customtransfer.drs.upsert=true
lfs.customtransfer.drs.multipart-threshold=10
lfs.customtransfer.drs.args=transfer
lfs.customtransfer.drs.concurrent=true
lfs.customtransfer.drs.enable-data-client-logs=false

drs.default-remote=calypr-dev
drs.remote.calypr-dev.type=gen3
drs.remote.calypr-dev.endpoint=https://calypr-dev.ohsu.edu/
drs.remote.calypr-dev.project=cbds-monorepos
drs.remote.calypr-dev.bucket=cbds

---

Problems With the Current Layout

1. Namespace pollution

Using top-level drs.* keys pollutes the global git config namespace and risks collisions.

2. Ambiguous ownership

These settings are only meaningful to the drs LFS transfer agent.

3. Harder debugging

Users expect LFS-related config under lfs.*.

4. Inconsistent with Git LFS patterns

Git LFS extensions consistently scope under lfs.customtransfer.<name>.*.

---

Proposed Change

All git-drs configuration must live under:

lfs.customtransfer.drs.*

Mapping

Current key	Proposed key
drs.default-remote	lfs.customtransfer.drs.default-remote
drs.remote.<name>.type	lfs.customtransfer.drs.remote.<name>.type
drs.remote.<name>.endpoint	lfs.customtransfer.drs.remote.<name>.endpoint
drs.remote.<name>.project	lfs.customtransfer.drs.remote.<name>.project
drs.remote.<name>.bucket	lfs.customtransfer.drs.remote.<name>.bucket

---

Backward Compatibility

Support both namespaces temporarily and emit a deprecation warning for drs.*.

---

Recommendation

Adopt a strict rule:

All configuration consumed by the drs Git LFS transfer agent must be prefixed with lfs.customtransfer.drs.

Yes I agree
