fix(utils): recognize SCP-style SSH remotes without a user in hasSSHProtocol - #12790
If this is a code change: I have written unit tests and/or added dogfooding pages to fully verify the new behavior.
If this is a new API or substantial change: the PR has an accompanying issue (closes #0000) and the maintainers have approved on my working plan.
Motivation
docusaurus deploy sets USE_SSH from the origin URL with hasSSHProtocol() when neither GIT_USER nor USE_SSH is set. Its SCP-style regex already makes the user@ part optional, but that branch only runs when URL.parse() returns null. When the user is left out, URL.parse() succeeds, because a host such as github.com or an SSH config alias such as github-work is a valid URL scheme:
git reads all three as SSH remotes. The alias form is common when one machine uses several GitHub accounts through ~/.ssh/config. For those remotes, deploy stops with "Please set the GIT_USER environment variable, or explicitly specify USE_SSH instead!" instead of deploying over SSH.
The fix runs the existing SCP-style check whenever the URL has no ://, which is the same condition git uses. A Windows drive path like C:/repo also matches that regex, so it is excluded explicitly and stays false, as before. URLs with :// behave as before (ssh: only).
Test Plan
New cases in packages/docusaurus-utils/src/__tests__/urlUtils.test.ts:
github.com:facebook/docusaurus.git and github-work:facebook/docusaurus.git are recognized. This case fails on main (expected false to be true) and passes with the fix.
C:/projects/docusaurus.git and C:\projects\docusaurus.git are not recognized.
All 37 tests in urlUtils.test.ts pass, and oxfmt --check passes on both files. I ran only that test file, not the full suite.
AI assistance: I used an AI coding assistant to help find and write this fix. I reviewed every line and ran the tests above myself.

Bug Fixes
Improved recognition of SSH Git addresses that omit the protocol, including host aliases and home-relative repository paths.
Windows drive paths are no longer mistaken for SSH addresses, while explicit SSH URLs continue to be recognized. This helps repository addresses be interpreted correctly across common formats and avoids treating local Windows paths as remote Git locations.
Included review availability: This review used your included allowance. Your plan provides up to 10 included reviews per hour; 9 remain after this review.
Walkthrough
hasSSHProtocol now detects protocol-less SCP-style addresses with or without a user part. It excludes Windows drive paths. Tests cover SSH host aliases, home-relative paths, and Windows drive paths.
Changes: SSH address detection
Layer / File(s)
Summary
Update SSH detection and tests packages/docusaurus-utils/src/urlUtils.ts, packages/docusaurus-utils/src/__tests__/urlUtils.test.ts
hasSSHProtocol checks SCP-style syntax when parsing fails or the input lacks ://. The pattern accepts ~ in paths and excludes Windows drive paths. Tests cover implied SSH addresses, host aliases, home-relative paths, and Windows drive paths.
The change appears ready to merge after normal checks; no unresolved issue was established in the changed SSH detection behavior.
Security architecture risk: Low · up to 91134
More Git remotes can automatically select SSH deployment, but explicit authentication choices and configured deployment destinations remain unchanged. No introduced security defect was established. Actual SSH key selection depends on the deployment environment.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — For the confirmed deployment consumer, control of the source origin can influence automatic transport selection when authentication overrides are absent. It does not alone select an arbitrary push destination; execution still requires invocation of deploy and uses the configured repository with the invoking environment's SSH authority.
Trust Boundaries and Controls
observed — Origin-based inference remains conditional on GIT_USER being absent and USE_SSH being undefined. Explicit USE_SSH=false prevents inference, while USE_SSH=true already selects SSH. HTTPS credential construction remains confined to the non-SSH branch.

Review comments at @packages/docusaurus-utils/src/urlUtils.ts:
- Line 331: Update the `sourceRepoUrl` Windows-path check to also exclude
drive-relative paths such as `C:projects/repo.git`, preventing local origins
from being treated as SSH URLs; add a test covering this case.
- Line 330: Update the SCP remote check for sourceRepoUrl to accept paths
beginning with `~` after the colon, so remotes such as `host:~git/repo.git` are
inferred as SSH; add a test covering this remote format.

Addressed both review points: SCP paths starting with ~ (host:~user/repo.git) are recognized now, and any single-letter host is treated as a Windows drive (as git does on Windows), so drive-relative C:repo paths no longer count as SSH. Tests added for both; all 11 hasSSHProtocol expectations pass.
