SetPolicy and policy check now compile per-dst SSH rules and replay each sshTests entry. The accept assertion treats check-action rules as reachable; the check assertion requires HoldAndDelegate on the matching rule. Boot reload warns and continues.
Adds a data-driven test that loads testdata/nodeattrs_results/*.hujson
and diffs the captured SaaS-rendered netmaps against headscale's
compileNodeAttrs output. Each capture is one scenario the SaaS
control plane has rendered against the same policy headscale is asked
to compile -- the test enforces shape parity per node.
tailnet_state_caps.go enumerates the caps SaaS emits where headscale
has no equivalent concept yet (user-role admin/owner, tailnet lock,
services host, app connectors, internal magicsock and SSH tuning,
tailnet-state metadata) plus the always-on baseline (admin, ssh,
file-sharing) and the taildrive pair. stripUnmodelledTailnetStateCaps
filters both sides of cmp.Diff so the comparison focuses on the
policy-driven caps. PeerCapMap encodes which caps the Tailscale
client reads from the peer view (suggest-exit-node when exit routes
are approved, etc.) for use by the mapper.
testcapture switches to typed tailcfg/netmap/filtertype/apitype
values so schema drift between the capture tool and headscale
becomes a compile error rather than a silent test failure. Existing
compat suites (acl, grants, routes, ssh, issue_3212) move to the
typed shape.
The 53 SelfNode netmap captures and the 7 anonymizer-corrupted
suggest-charmander -> suggest-exit-node restorations in
routes_results / issue_3212 ride along.
The 39 SSH-*.hujson files in hscontrol/policy/v2/testdata/ssh_results/
were legacy hand-written "expected SSH rules" snippets superseded by
the lowercase tscap captures (ssh-*.hujson). The active loader in
TestSSHDataCompat globs ssh-*.hujson; filepath.Glob is case-sensitive
on Linux so the uppercase set was loaded by no test.
The duplication caused permanent dirty git state on case-insensitive
filesystems (APFS, NTFS) where only one of SSH-A1.hujson and
ssh-a1.hujson can physically exist in the working tree.
Add an assertion to TestSSHDataCompat that the loader picks up every
*.hujson under ssh_results/ so future fixture migrations cannot leave
stranded files behind.
Fixes#3240
Rename all 594 test data files from .json to .hujson and add
descriptive header comments to each file documenting what policy
rules are under test and what outcome is expected.
Update test loaders in all 5 _test.go files to parse HuJSON via
hujson.Parse/Standardize/Pack before json.Unmarshal.
Add cross-dependency warning to via_compat_test.go documenting
that GRANT-V29/V30/V31/V36 are shared with TestGrantsCompat.
Add .gitignore exemption for testdata HuJSON files.
Remove unused error variables (ErrGrantViaNotSupported, ErrGrantEmptySources, ErrGrantEmptyDestinations, ErrGrantViaOnlyTag) and the stale TODO for via implementation. Update compat test skip reasons to reflect that user:*@passkey wildcard is a known unsupported feature, not a pending implementation.
Updates #2180
