webdav_patch.hurl and nc_webdav_patch.hurl existed with real coverage
since the original PATCH commits but were never added to
tests/api/run.sh, so just api-test/CI silently skipped them. Wire both
in, fix nc_webdav_patch.hurl's header-after-[BasicAuth] ordering bug
that meant it had never actually passed, and add two new
consistency-focused files chaining PATCH operations with
cross-protocol/cross-surface verification:
- webdav_patch_consistency.hurl: chained overwrites with ETag-change
checks, GET/HEAD/PROPFIND cross-protocol agreement, quota-507
leaving the file byte-for-byte unchanged, direct_put_max_bytes
prefix/suffix regression coverage.
- nc_webdav_patch_consistency.hurl: Editor/Viewer/Outsider permission
matrix, cross-surface lock interop, quota-507 via the NC surface.
Running these surfaced two real bugs in the NC PATCH handler, both
fixed here:
- The write step mapped every error (including a legitimate anti-enum
permission denial) to a raw 500 instead of AppError::from(e), unlike
the plain surface. A Viewer without Update permission got a 500
leak instead of the expected 404.
- nc_to_internal_path() didn't strip the leading '/' that chroot.path
carries from StoragePath::to_string(), so a LOCK taken via /webdav/
silently failed to block PATCH via /remote.php/dav/ on the same
file — the exact-string lock-store lookup never matched. Added a
regression unit test.
RFC 4918 §9.7.1 forbids partial updates on PUT; this adds PATCH as the
supported mechanism instead, via an X-Update-Range header (bytes=<start>-<end>
or append). Reuses the existing CAS/dedup pipeline by splicing the request
body between the file's untouched prefix/suffix byte ranges and re-ingesting
as one continuous stream, so unedited chunks dedup for free.
