* azureblob - Add support for Azure Storage Emulator to test things locally.
Testing - Verified changes by testing manually.
* docs: update azureblob docs to reflect support of storage emulator
This bug was introduced as part of adding context to the backends and
slipped through the net because the About call did not have an
interface assertion in the sftp backend.
I checked there were no other missing interface assertions on all the
optional methods on all the backends.
In f544234 we removed the global flags from each command as it was
making each page very big and causing 1000s of lines of duplication in
the man page.
This change adds a new flags page with all the global flags on and
links each command page to it.
Fixes#3273
- 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.
It was discovered after lots of experimentation that the cmd/mount
tests have a tendency to lock up if GOMAXPROCS=1 or 2. Since the
Travis builders only have 2 vCPUs by default, this happens on the
build server very often.
This workaround increases GOMAXPROCS to make the mount test lockup
less likely.
Ideally this should be fixed in the mount tests at some point.
Before this change rclone attempted to set the "updated" field in
uploaded objects to the modification time.
However when this modification time was before 1970, google drive
would return the rather cryptic error:
googleapi: Error 400: Invalid value for UnsignedLong: -42000, invalid
However API docs: https://cloud.google.com/storage/docs/json_api/v1/objects#resource
state the "updated" field is read only and tests confirm that. Even
though the field is read only, it looks like Google parses it.
This change therefore removes the attempt to set the "updated" field
(which was doing nothing anyway) and fixes the problem uploading pre
1970 files.
See #3196 and https://forum.rclone.org/t/invalid-value-for-unsignedlong-file-missing-date-modified/3466
Before this change using --user and --pass was impossible on the rc
from a browser as the browser needed to make the OPTIONS request first
before sending Authorization: headers, but the OPTIONS request
required an Authorization: header.
After this change we allow OPTIONS requests to go through without
checking the Authorization: header.
