parseColonPath split the anchor asymmetrically (root trimmed the delimiter
colon as part of a literal "/root:" prefix, item cut on it), and the root
branch's comment talked about the driveID which isn't this function's
concern. Split once at the first colon into anchor + rest, then classify
the anchor (exactly "/root", or "/items/{id}" with a single-segment id).
Same behavior, easier to follow.
Also add explicit coverage for the rule that a suffix requires a second
colon: "/root:/Documents/children" (no second colon) is the path
"/Documents/children", not the path "/Documents" with a "/children"
suffix. Two tests pin it end-to-end - it must route to the bare item (not
/items/{id}/children) and Stat must receive the full path.
Review feedback: the two colon-syntax regexes were hard to read. Since the
middleware is scoped to /drives/{driveID}, the RoutePath it inspects is just
the sub-path (/root:/... or /items/{id}:/...), so a regex buys nothing.
Replace rootColonRe/itemColonRe (and the matchInto/extract helpers) with a
single parseColonPath that uses plain string operations
(HasPrefix/TrimPrefix/TrimSuffix/Cut), one commented step at a time.
Behavior is unchanged; the existing table tests (trailing colon, no suffix,
deep paths, multi-segment suffixes, item-anchored, encoded paths) still pass
and pin it.
Addresses review feedback: a sub-router middleware can re-route after all,
as long as it rewrites chi.RouteContext().RoutePath instead of r.URL.Path.
Once chi has descended into a sub-router its routeHTTP matches against
rctx.RoutePath and ignores r.URL.Path, which is why the earlier top-level
registration was thought to be required.
Move ResolveGraphPath off the top-level mux.Use and attach it to the
/drives/{driveID} sub-routers (v1.0 + v1beta1). It now reads driveID from
chi.URLParam and matches against RoutePath (the part below the drive), so
the regexes drop the version + drive prefix entirely.
RoutePath carries the percent-encoded wire form (Graph.ServeHTTP sets
RawPath), so the captured driveID/itemID/path are PathUnescape'd exactly
once - reproducing the decoded r.URL.Path a normal handler would see,
without the previous RawPath/EscapedPath workaround. r.URL.Path is now
left untouched; only chi's internal RoutePath is rewritten.
Tests are reworked to drive requests through a chi router mirroring the
production nesting (including the Graph.ServeHTTP RawPath behavior), so
chi's sub-router middleware ordering, RoutePath encoding and param
round-trip are all covered indirectly: a chi upgrade that changes any of
them fails these tests instead of silently breaking colon-path lookups.
Adds explicit coverage for percent-decoding (%20, %252F) and the `$`/`!`
sub-delimiter id round-trip.
Codacy flagged the colon-path middleware comment claiming both `$`
and `!` need percent-encoding for chi's tree match, while the
implementation only calls r.URL.RawPath = r.URL.EscapedPath() which
does not encode either character per the suggestion's reading.
In practice EscapedPath does encode `!` as `%21` (only `?` is the
hardcoded escape, `!` is escaped because Go's net/url treats it as
needing encoding outside specific contexts). It leaves `$` literal,
which chi handles fine. chi.URLParam returns the encoded segment
verbatim, and downstream OpenCloud handlers (parseIDParam,
GetDriveAndItemIDParam) already PathUnescape before parsing IDs, so
the round-trip works end-to-end. The acceptance tests on this
branch already exercise this with real `$`/`!`-containing IDs.
Add a focused unit test that mounts the middleware behind chi,
sends a colon URL, and asserts the actual contract:
- driveID (only `$`): chi.URLParam returns it literal
- itemID (with `!`): PathUnescape(chi.URLParam(...)) == original
Update the misleading comment so future readers (and reviewers) see
what the encoding actually does and which downstream contract it
relies on.
Cover the rewrite shapes the middleware handles end-to-end against a
real OpenCloud server: root-anchored, item-anchored, deep paths,
trailing colon, and the "/<path>:/<suffix>" sub-route form. Also
assert that NOT_FOUND and PERMISSION_DENIED both collapse to 404.
The /permissions sub-route is registered only at /v1beta1, and the
v1beta1 GetDriveItem handler is share-jail-only, so the v1beta1
mount of the middleware is exercised through the permissions
scenario, since there is no other v1beta1 endpoint that works for
regular personal-drive items.
Three more Copilot review nits on the colon-syntax middleware:
- CS3 Stat returning UNAUTHENTICATED now surfaces as HTTP 401 (was 500
via the default-case fallback). Distinct sentinel + handler branch.
- Item-anchored form (/drives/{driveID}/items/{itemID}:/...) now
validates that driveID's storage/space prefix matches the itemID's,
short-circuiting to 400 InvalidRequest on mismatch instead of doing
a CS3 Stat that would only fail at the handler layer.
- ParseID failures on the anchor id now surface as 400 (was 404). In
practice this branch is defensive — storagespace.ParseID is lenient
and only errors on empty input, which the regex already filters out
— but the right semantic for malformed client input is 400, not 404.
Tests: added two new cases (UNAUTHENTICATED → 401, drive/item id
mismatch → 400). The "malformed drive id" case Copilot suggested
isn't reachable in practice given ParseID's leniency, so it's not
covered.
Two follow-up Copilot review nits on the colon-syntax middleware:
- Don't blank r.URL.RawPath after the rewrite. Graph.ServeHTTP sets
RawPath = EscapedPath() as a workaround for chi's parameter-binding
quirks with `$`/`!` in IDs (see go-chi/chi#641). Clearing RawPath
for rewritten requests negates that workaround. Re-establish the
same invariant after the rewrite.
- Tests previously used log.NewLogger(), which mutates global zerolog
state. Switch to log.NopLogger() — order-independent, no global
side effects.
- Drop double-decoding of URL path components. r.URL.Path is already
decoded by net/http; calling url.PathUnescape again would let crafted
inputs like "%252F" become "/", changing path semantics. Path and
anchor-id strings now go straight to utils.MakeRelativePath /
storagespace.ParseID.
- Distinguish operational errors from "not found". Gateway selection
failure, RPC transport errors, and unexpected CS3 status codes now
surface as 500 (don't mask outages); only NOT_FOUND and PERMISSION_DENIED
collapse to 404 (no existence disclosure). Implemented via a sentinel
errPathNotFound + a 500 fall-through.
- Refactor the two regex-handling branches in rewriteColonPath to share a
resolution path via a small colonMatch struct + matchInto/extract helpers.
Removes the SonarCloud duplication finding without changing behavior.
- Update the docstring on ResolveGraphPath to reflect that the rewrite
preserves the requested API version (/{version}/...) rather than
hard-coding /v1beta1/...
- Test cleanup: register t.Cleanup to remove the per-subtest selector
entry from pool's global selectors map after the subtest, and update
the "unexpected status" case to expect 500 (matches the new error
semantics).
Adds a chi middleware that detects MS Graph colon-syntax URLs and rewrites
them to the canonical /items/{itemID}/... form before chi performs route
matching. Existing handlers, routes, and GetDriveAndItemIDParam stay
unchanged.
Two URL shapes are recognized at both /v1.0 and /v1beta1:
/drives/{driveID}/root:/<path>[:/<suffix>][:]
/drives/{driveID}/items/{itemID}:/<relativePath>[:/<suffix>][:]
Path resolution runs as the request user via CS3 Stat. Both NOT_FOUND and
PERMISSION_DENIED collapse to a 404 response so existence isn't disclosed
to unauthorized callers. URLs without colon syntax fast-path through with
a single substring check. The original URL is stashed in request context
under OriginalPathContextKey for downstream tracing/logging.
The middleware is registered as a top-level mux.Use so it runs before any
route matching: chi middleware on a sub-router runs after the prefix is
matched but cannot redirect to a different leaf route. Top-level
middleware lets URL rewriting actually re-route the request.
Tests cover regex matching across versions, all rewrite variants
(root/items anchored, with/without suffix, with/without trailing colon,
deep paths), NOT_FOUND -> 404, PERMISSION_DENIED -> 404 (security: no
existence disclosure), and original-URL preservation in request context.
#1877 reordered the api-test teardown to delete spaces before users, so the
state where a project space's manager has been deleted is no longer exercised.
This adds explicit coverage for it: the only manager of a project space is
deleted, and a space admin can still list and delete (disable + purge) the space.

opencloud-eu/reva#655 changes the TUS create response for an invalid name
from 412 to 400. Update the invalid-name scenario to match.
Each example now carries its own expected status in an <http-status-code>
column. Names that fail ValidateName expect 400. The three folder/file rows
stay 412: filename() applies path.Base first, so "folder/file" becomes the
valid leaf "file" and never reaches the changed branch.
lowLevelCreationExtension.feature is unchanged; its missing-Upload-Length
case still returns 412.
