A source reader which returns EOF before supplying as many bytes as it
declared should not cause a backend Put to hang, panic or create an
object claiming the declared size.
The layers above detect a truncated transfer by comparing sizes after
the upload, so a backend may either return an error or create a
shorter object.
See #9704
Every write operation waits for the server's processing tasks which
currently take minutes each, so the full test suite takes much longer
than the timeout. Running with -short skips the FsEncoding subtests
(which are already on the ignore list) and the chunked upload tests,
removing a large number of these waits.
The old rclone-integration-test item has accumulated years of catalog
task churn and IA now deprioritises and periodically holds its tasks,
which makes the tests wait on the server's processing tasks for a
very long time. Start again with a fresh item (created with noindex
set so the test files stay out of IA's search index).
ImageKit can't store zero length files. The test only skips itself
when the failure is reported synchronously, but with --vfs-cache-mode
writes the writeback happens asynchronously and deliberately swallows
the error, so the test fails on the missing files. Other backends
which can't store empty files already ignore this test.
Cloudinary's search API which NewObject uses is eventually
consistent, so the --compare-dest lookup of a just uploaded file
misses it and the test fails. TestCopyFileCompareDest is already
ignored for the same reason.
Layers which wrap backends, such as the hasher backend and the VFS
cache, use fs.Fingerprint to detect whether an object has changed.
This only works if the object a backend hands back from a write
operation is identical to the object a fresh listing returns. If a
backend keeps the source's nanosecond precision modtime in memory
while the server stores milliseconds, or omits a hash the server
knows, every fingerprint comparison fails and cached hashes or files
are silently invalidated.
The existing tests compared modtimes within f.Precision() so they
could not detect these sub-precision divergences.
Add a checkFingerprint helper which asserts the fast and slow
fs.Fingerprint of the object returned from a write operation exactly
match those of the object read back from the remote, and wire it into
all the write paths which return or mutate an object: Put (all
variants), PutStream, large and streamed uploads, Update, SetModTime,
server side Copy and Move, and the metadata mutating Copy/Move
subtests.
Rework the ObjectOpenFingerprint test to use the same helper against
a fully read reference object, with subtests reporting which kind of
read is being checked.
Add TestObjectOpenFingerprint which reads an object's fast and slow
fingerprints, then opens it in several ways - a full read, a seek read
and ranged reads - and after a refresh, checking the fingerprint never
changes.
TestS3Minio brings up a minio container via the fstest/testserver
framework, which exec's bash init.d scripts that shell out to docker.
This is not available on all platforms - Windows has no POSIX shell to
run the scripts, and macOS CI runners have no docker daemon - which
caused the build to fail there.
Add testy.SkipUnlessDocker to detect whether the framework can run and
skip the test when it cannot.
The bisync normalization test relies on uploading distinct NFC and NFD
versions of the same filename and on the backend supporting in-place
modtime updates. Dropbox normalizes unicode server-side (NFD -> NFC)
and can't set modtime in place, so the test inevitably takes a
different code path on Dropbox and the log diverges from the golden
output without any functional difference.

Until now test_all relied entirely on per-goroutine defer finish()
calls in fstest/runs to stop test servers. A Ctrl-C, kill, or panic
aborted those defers and left docker containers running, breaking the
next run.
Register testserver.CleanupAll with lib/atexit so SIGINT/SIGTERM
delivery runs the sweep automatically. Also defer atexit.Run for the
normal exit and unrecovered-panic paths, and call it explicitly
before os.Exit(1) since os.Exit does not fire defers. The fs.Fatalf
call sites above only fire before any server starts so they need no
explicit sweep.
Cleanup today is entirely per-goroutine via the stop closure that Start
returns. If the driver process is killed or panics, those deferred
stops never run and the underlying container keeps running.
Track every remote Start has brought up in a process-local map, and
expose CleanupAll which force-stops each tracked remote via the new
run.bash "force-stop" verb. The returned stop closure is now
sync.Once-wrapped so it and CleanupAll can both fire harmlessly. No
callers yet; wired up in fstest/test_all in a follow-up commit.
run.bash holds a persistent refcount file in the shared state directory
so multiple concurrent tests can share a single container. If a prior
test_all run is killed (e.g. Ctrl-C), the count never reaches zero on
the next run and the container is never stopped - forcing manual
cleanup.
Three fixes, all in fstest/testserver/init.d/run.bash:
- On start, if the refcount is non-zero but no container is running,
treat it as zero. Stops leaking through future runs.
- reset now rm -rfs RUN_ROOT (the per-server state) instead of
RUN_BASE (the shared parent) which was clobbering sibling services.
- New force-stop verb unconditionally stops the container and zeroes
the refcount. This is the primitive that the Go-side cleanup sweep
will call at end-of-run.
This change adds first-class metadata support to the Azure Blob backend,
including headers, user metadata, tags, and modtime overrides, and wires
it through uploads and server-side copies.
There is a behavior change in that rclone will now set the "mtime"
custom metadata when doing server side copies to azure and the
`--metadata` argument is given.
- Map standard headers: cache-control, content-disposition, content-encoding,
content-language, content-type to corresponding x-ms-blob-* HTTP headers.
- Map user metadata: any non-reserved keys (excluding x-ms-*) are sent as
blob user metadata. Keys are normalized to lowercase for consistency.
- Support tags: parse `x-ms-tags` as a comma-separated list of key=value
pairs and apply them on uploads and copies.
- Support mtime override: accept `mtime` in metadata (RFC3339/RFC3339Nano)
to override the stored modtime persisted in user metadata.
Added support for reading and writing zstd-compressed archives in seekable format
using "github.com/klauspost/compress/zstd" and
"github.com/SaveTheRbtz/zstd-seekable-format-go/pkg".
Bumped Go version from 1.24.0 to 1.24.4 due to requirements of
"github.com/SaveTheRbtz/zstd-seekable-format-go/pkg".
Before this fix there were various issues with the test server
framework, most noticeably servers stopping when they shouldn't
causing timeouts. This was caused by the reference counting in the Go
code not being engineered to work in multiple processes so it was not
working at all properly.
This fix moves the reference counting logic to the start scripts and
in turn removes that logic from the Go code. This means that the
reference counting is now global and works correctly over multiple
processes.
The bouncestorage image hasn't been updated for 4 years and has this
message at the top of the docs:
This repository is outdated; please use dockerswiftaio/docker-swift instead.
However, dockerswiftaio/docker-swift hasn't been updated for 2 years.
Switch to openstackswift/saio instead, which is getting regular updates.
This requires some minor changes to one test, and how we start the
container.
On my system there needs to be a slight pause between stopping and
checking to see if SwiftAIO has stopped. Without the pause the tests fail for
a non-obvious reason.
Instead of using a magic sleep, re-use the retry logic that is used for
starting the test server.
