* log buffer: wake the interval loop on shutdown instead of sleeping through it
loopInterval parked in time.Sleep(flushInterval) and only re-checked
IsStopping when it woke, so a buffer shut down early kept both loop
goroutines - and the PreviousBufferCount+1 slabs of BufferSize they
reach - alive for up to a full interval afterwards. Select on shutdownCh
against a ticker instead, and give the loops a WaitGroup so a test can
observe that they exit.
* test: release the filers the server tests build
Every helper here left its filer's meta log buffer running, so each test
pinned PreviousBufferCount+1 buffers of BufferSize for the rest of the
run: ~3.5GB of live heap across the package, which overruns the address
space on linux/386 and kills the 32-bit job with an out-of-memory throw.
Thread the test through the helpers so the buffer is shut down on
cleanup, and shut the subscribe harness's filer down outright - its
deletion loop keeps the whole filer reachable otherwise. That harness
quiesces its flush path first, since Filer.Shutdown closes the store a
flush still in flight would write through.
* filer: authorize TUS existing-session verbs against the validated stored target
Scope-check on TUS HEAD/PATCH/DELETE only populated a resource path for POST,
so a prefix-restricted token that learned another tenant's session id could act
on that session and land content at a TargetPath its own AllowedPrefixes forbid.
Split the filer JWT check into authenticateFilerJwt (signature and method) and
authorizeFilerJwtPaths (resource scope), and make the scope check fail closed:
a prefix-restricted token with no resolved resource path is denied instead of
authorized on signature alone. The TUS handler now authenticates first, reads
and validates the session once, authorizes the stored TargetPath, then operates
on that single pinned snapshot. readTusSessionInfo rejects a session whose id,
target or size is unusable, and getTusSession is split so the authorization
lookup no longer lists chunks.
* filer: reject non-canonical TUS upload ids
The uploads route took the first path component as the session id, so a trailing
path or other non-canonical spelling aliased one session under several URLs.
Require the id to be a canonical UUID, the only form the server mints, both at
routing and when reading a session's metadata, so one URL maps to one resource.
* filer: revalidate the pinned TUS session before completing an upload
Completion re-read chunks but not the session identity, so a PATCH finishing
after a concurrent DELETE or metadata replacement could still land at the id's
stored path. Before completing, confirm the session still exists and its target,
size and creation time are unchanged from the authorized snapshot; otherwise the
completion fails instead of writing to a path the request never authorized.
* filer: log TUS session lookup failures before returning not-found
readTusSessionInfo and loadTusSessionChunks failures answered "not found" with
no log line, so a transient filer or listing error was indistinguishable from a
genuinely missing session. Log the lookup at V(1) (a missing session is common
and benign) and the chunk-load error at Errorf (the session already resolved).
* filer: require JWT authorization on TUS upload endpoints
filerHandler and readonlyFilerHandler run every request through
maybeCheckJwtAuthorization, but the TUS routes were registered only
behind filerGuard.WhiteList, which is a pass-through for the filer (its
guard is built with an empty whitelist), and no TUS handler called the
JWT check. So with jwt.filer_signing.key set, normal PUT/POST/DELETE
were authorized while the TUS endpoints were not.
Run the same check in tusHandler before routing: HEAD uses the read key,
POST/PATCH/DELETE use the write key, and creation scopes a
prefix-restricted token against the resolved target path. OPTIONS stays
open for capability discovery.
* filer: enforce read-only and WORM rules on TUS completion
completeTusUpload wrote the final entry with CreateEntry directly,
skipping the read-only and WORM checks the normal write path applies.
Reject completion when the target prefix is read-only or the existing
entry at the target is WORM-enforced.
* filer: align TUS write path with the normal write path
Resolve the create target with a guaranteed leading slash so a
prefix-restricted token and the stored path stay absolute even if
TusBasePath were set with a trailing slash. Reject read-only prefixes at
session creation before any chunk is written, and map read-only and WORM
rejections at completion to 507 and 403 instead of a generic 500.
* filer: cover method-restricted TUS tokens in the auth test
