The updates the authentication to include
- Auth from the environment
1. Environment Variables
2. Managed Service Identity Credentials
3. Azure CLI credentials (as used by the az tool)
- Account and Shared Key
- SAS URL
- Service principal with client secret
- Service principal with certificate
- User with username and password
- Managed Service Identity Credentials
And rationalises the auth order.
Normally rclone will check the container exists before uploading if it
hasn't listed the container yet.
Often rclone will be running with a limited set of permissions which
means rclone can't create the container anyway, so this stops the
check.
This will save a transaction.
This commit switches from using the old Azure go modules
github.com/Azure/azure-pipeline-go/pipeline
github.com/Azure/azure-storage-blob-go/azblob
github.com/Azure/go-autorest/autorest/adal
To the new SDK
github.com/Azure/azure-sdk-for-go/
This stops rclone using deprecated code and enables the full range of
authentication with Azure.
See #6132 and #5284
Before this fix, the chunksize calculator was using the previous size
of the object, not the new size of the object to calculate the chunk
sizes.
This meant that uploading a replacement object which needed a new
chunk size would fail, using too many parts.
This fix fixes the calculator to take the size explicitly.
Before this change attempting NewObject on a SAS URL's root would
crash the Azure SDK.
This change detects that using the code from this previous fix
f7404f52e7 azureblob: fix crash when listing outside a SAS URL's root - fixes#4851
And returns not object not found instead.
It also prevents things being uploaded to the root of the SAS URL
which also crashes the Azure SDK.
After speed testing it was discovered that upload speed goes up pretty
much linearly with upload concurrency. This patch changes the default
from 4 to 16 which means that rclone will use 16 * 4M = 64M per
transfer which is OK even for low memory devices.
This adds a note that performance may be increased by increasing
upload concurrency.

This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.
This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.
In
05f128868f azureblob: add --azureblob-no-head-object
we incorrectly parsed the size of the object as the Content-Length of
the returned header. This is incorrect in the presense of Range
requests.
This fixes the problem by parsing the Content-Range header if
avaialble to read the correct length from if a Range request was
issued.
See: #5734
Includes adding support for additional size input suffix Mi and MiB, treated equivalent to M.
Extends binary suffix output with letter i, e.g. Ki and Mi.
Centralizes creation of bit/byte unit strings.
This change checks the context whenever rclone might retry, and
doesn't retry if the current context has an error.
This fixes the pathological behaviour of `--max-duration` refusing to
exit because all the context deadline exceeded errors were being
retried.
This unfortunately meant changing the shouldRetry logic in every
backend and doing a lot of context propagation.
See: https://forum.rclone.org/t/add-flag-to-exit-immediately-when-max-duration-reached/22723
Before this change, attempting to update an archive tier blob failed
with a 409 error message:
409 This operation is not permitted on an archived blob.
This change detects if we are overwriting a blob and either generates
the error (if `--azureblob-archive-tier-delete` is not set):
can't update archive tier blob without --azureblob-archive-tier-delete
Or deletes the blob first before uploading it again (if
`--azureblob-archive-tier-delete` is set).
Fixes#4819
Before this change if you attempted to list a remote set up with a SAS
URL outside its container then it would crash the Azure SDK.
A check is done to make sure the root is inside the container when
starting the backend which is usually enough, but when two SAS URL
based remotes are mounted in a union, the union backend attempts to
read paths outside the named container. This was causing a mysterious
crash in the Azure SDK.
This fixes the problem by checking to see if the container in the
listing is the one in the SAS URL before listing the directory and
returning directory not found if it isn't.
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.
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.
