feat: REPO_URL=local sentinel to skip git update entirely - #124
Conversation
DTLRepo always ran a clone or a fetch, even when REPO_PATH already held the library contents locally. validate_git_url() rejected the old 'local' value outright, and even a valid URL still triggered a real git fetch against the remote on every run. REPO_URL=local now skips Repo(), clone_from(), and fetch() entirely. REPO_PATH is used as-is and must already contain device-types/, module-types/, and rack-types/ (no .git required, and none is used).

Validate the local repository layout, not only the directory.
The current check accepts an empty or unrelated directory. The early return then skips cloning and pulling, so the import can continue without the required DTL library files. Validate the expected repository layout before logging and returning, and add a regression test for an empty directory.

* fix(repo): add REPO_URL=local sentinel to bypass git entirely (#124) DTLRepo always ran a clone or a fetch, even when REPO_PATH already held the library contents locally. validate_git_url() rejected the old 'local' value outright, and even a valid URL still triggered a real git fetch against the remote on every run. REPO_URL=local now skips Repo(), clone_from(), and fetch() entirely. REPO_PATH is used as-is and must already contain device-types/, module-types/, and rack-types/ (no .git required, and none is used). * fix(repo): validate the local library layout and share the check with export (#126) * fix(repo): validate the local library layout and share the check with export REPO_URL=local only checked that REPO_PATH was a directory. An unrelated or empty path passed that check, and discover_vendors skips type directories that are absent, so the run imported nothing and still exited 0. Export mode already had the check it needed, in Exporter._verify_repo_available. Both sides now read one definition of what makes a checkout a library: LIBRARY_TYPE_DIRS and library_dirs_present() in core/repo.py. The sentinel value moves to LOCAL_REPO_URL in core/config.py, beside the other REPO_* defaults, so config and repo cannot drift on it. Local mode still skips validate_repo_path on purpose: that check demands write access, which a read-only or air-gapped mount cannot give, and no import step writes to REPO_PATH. A test pins the read-only case. REPO_BRANCH is ignored under the sentinel, so a run that sets both now says so through the existing config notice mechanism instead of looking like it checked the branch out. Documents the mode in the README and .env.example, including the read-only Docker mount, which is the case that motivated the sentinel. * fix(import): treat an absent type root as empty instead of crashing The layout check accepts any one of device-types/, module-types/, and rack-types/, matching what export mode already accepted. plan_vendor then called get_devices() on all three regardless, and get_devices() lists the directory, so a local checkout holding only some of them raised FileNotFoundError before importing the types it did hold. A device-types-only library is the likeliest local layout, and it crashed on module-types. _parse_vendor_racks already had the guard this needed. It is now _parse_vendor_files and all three roots go through it, so the guard cannot apply to one root and not the others again. The repo mock in test_nb_dt_import pointed at /tmp/devices, /tmp/modules and /tmp/rack-types, paths that never existed. Nothing stat'd them, so the mock passed for a filesystem that was not there, which is why this went unseen. It now points at a real empty library tree, and the tests that matched on those literal paths match on the directory names instead.

Problem
Import mode always runs a git operation. On a fresh
REPO_PATHit clones. On an existing checkout it fetches from origin. There's no way to just point the tool at a directory that already has the library files and have it read them, nothing else.This used to work by accident with
REPO_URL=local, back beforevalidate_git_url()existed. Once that validator landed,'local'got rejected as an invalid URL, since it matches none ofhttps://,ssh://,git@host:, orfile://. Even fixing the URL string wouldn't fully solve it though:pull_repo()callsself.repo.remotes.origin.fetch(prune=True)unconditionally whenever.gitexists atREPO_PATH, regardless of whatREPO_URLis set to. Anyone running this in an air-gapped environment, or just working from a local copy they manage themselves, has no way to avoid that fetch.Export mode already handles this correctly —
--export-diffnever clones or updates, it just reads whatever's atREPO_PATH. Import mode has no equivalent.Fix
DTLRepo.__init__now checks forREPO_URL=local(case-insensitive) before touching git at all. When set, it verifiesREPO_PATHexists and returns immediately withoutRepo(),clone_from(), orfetch().REPO_PATHis expected to already containdevice-types/,module-types/,rack-types/, and ideallytests/known-*.jsonfor the slug-index fast path, the same layout the tool produces on a normal clone.No
.gitdirectory is required or read in this mode.Behavior change
None for existing users.
