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 replaces built-in os.MkdirAll with a patched version that stops the recursion
when reaching the volume part of the path. The original version would continue recursion,
and for extended length paths end up with \\? as the top-level directory, and the error
message would then be something like:
mkdir \\?: The filename, directory name, or volume label syntax is incorrect.
This adds a context.Context parameter to NewFs and related calls.
This is necessary as part of reading config from the context -
backends need to be able to read the global config.
Before this change we didn't calculate any hashes for test files
created in the Run framework.
This means that files were uploaded to S3 without a `Content-MD5`
header. This in turn caused minio to disengage `--compat` mode which
in turn caused the `TestSyncAfterChangingModtimeOnlyWithNoUpdateModTime`
test to fail in `fs/sync`.
After this change we supply all hashes supported by the destination Fs
on the upload object.
This means that the `Content-MD5` is set and minio engages `--compat`
mode to fix the problem. Using `--compat` on the command line also
fixes the problem.
This much better replicates how objects are actually uploaded with
operations.Copy so should improve the integration tests.
The fs cache makes test runs no longer independent and this can cause
a problem with some tests.
Clearing the fs cache between tests runs fixes the problem.
This was spotted by @cenkalti as part of merging #3469
- 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.
Before this change TestPurge would remove a container and subsequent
tests would fail because the container was still being deleted so
couldn't be created.
This was fixed by introducing an fstest.NewRunIndividual() test runner
for TestPurge which causes the test to be run on a new container.
The purpose of this is to make it easier to maintain and eventually to
allow the rclone backends to be re-used in other projects without
having to use the rclone configuration system.
The new code layout is documented in CONTRIBUTING.
