Before this change backends which supported more than one hash (eg
pcloud) or backends which wrapped backends supporting more than one
hash (combine) would fail the TestMultithreadCopy and
TestMultithreadCopyAbort with an error like
Failed to make new multi hasher: requested set 000001ff contains unknown hash types
This was caused by the tests limiting the globally available hashes to
the first hash supplied by the backend.
This was added in this commit
d5d28a7513 operations: fix overwrite of destination when multi-thread transfer fails
to overcome the tests taking >100s on the local backend because they
made every single hash that the local backend. It brought this time
down to 20s.
This commit fixes the problem and retains the CPU speedup by only
applying the fix from the original commit if the destination backend
is the local backend. This fixes the common case (testing on the local
backend). This does not fix the problem for a backend which wraps the
local backend (eg combine) but this is run only on the integration
test machine and not on all the CI.
Before this change multipart downloads to the local disk with
--metadata failed to have their metadata set properly.
This was because the OpenWriterAt interface doesn't receive metadata
when creating the object.
This patch fixes the problem by using the recently introduced
Object.SetMetadata method to set the metadata on the object after the
download has completed (when using --metadata). If the backend we are
copying to is using OpenWriterAt but the Object doesn't support
SetMetadata then it will write an ERROR level log but complete
successfully. This should not happen at the moment as only the local
backend supports metadata and OpenWriterAt but it may in the future.
It also adds a test to check metadata is preserved when doing
multipart transfers.
Fixes#7424
Before this change it wasn't possible to see where transfers were
going from and to in core/stats and core/transferred.
When use in rclone mount in particular this made interpreting the
stats very hard.
Before this change, if a multithread upload failed (let's say the
source became unavailable) rclone would finalise the file first before
aborting the transfer.
This caused the partial file to be written which would overwrite any
existing files.
This was fixed by making sure we Abort the transfer before Close-ing
it.
This updates the docs to encourage calling of Abort before Close and
updates writerAtChunkWriter to make sure that works properly.
This also reworks the tests to detect this and to make sure we upload
and download to each multi-thread capable backend (we were only
downloading before which isn't a full test).
Fixes#7071
Previously only the fs being checked on gets passed to
GetModifyWindow(). However, in most tests, the test files are
generated in the local fs and transferred to the remote fs. So the
local fs time precision has to be taken into account.
This meant that on Windows the time tests failed because the
local fs has a time precision of 100ns. Checking remote items uploaded
from local fs on Windows also requires a modify window of 100ns.
This is done by making fs.Config private and attaching it to the
context instead.
The Config should be obtained with fs.GetConfig and fs.AddConfig
should be used to get a new mutable config that can be changed.
In bde0334bd8 "operations: fix setting the timestamp on Windows
for multithread copy" the test for multithread copy failed to take
into account the modify window of the remote under test.
Before this fix we attempted to set the modification time on the file
when it was open. This works fine on Linux but not on Windows. The
test was also incorrect testing the source file rather than the
destination file.
This closes the file before setting the modification time and fixes
the tests.
Fixes#3994
This was factored from fstest as we were including the testing
enviroment into the main binary because of it.
This was causing opening the browser to fail because of 8243ff8bc8.
Introduce stats groups that will isolate accounting for logically
different transferring operations. That way multiple accounting
operations can be done in parallel without interfering with each other
stats.
Using groups is optional. There is dedicated global stats that will be
used by default if no group is specified. This is operating mode for CLI
usage which is just fire and forget operation.
For running rclone as rc http server each request will create it's own
group. Also there is an option to specify your own group.
This is done to make clear ownership over accounting object and prepare
for removing global stats object.
Stats elapsed time calculation has been altered to account for actual
transfer time instead of stats creation time.
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions
Context propagation is needed for stopping transfers and passing other
request-scoped values.
