This implements the OpenChunkWriter interface for azureblob which
enables multi-thread uploads.
This makes the memory controls of the s3 backend inoperative; they are
replaced with the global ones.
--azureblob-memory-pool-flush-time
--azureblob-memory-pool-use-mmap
By using the buffered reader this fixes excessive memory use when
uploading large files as it will share memory pages between all
readers.
This introduces a new fs.Option flag, Sensitive and uses this along
with IsPassword to redact the info in the config file for support
purposes.
It adds this flag into backends where appropriate. It was necessary to
add oauthutil.SharedOptions to some backends as they were missing
them.
Fixes#5209
Before this change we were incorrectly identifying the root directory
of the listing and adding it into the listing.
This caused higher layers of rclone to emit the error above.
See #7038
This fixes the azureblob backend so it builds again after the SDK
changes.
This doesn't update bazil.org/fuse because it doesn't build on FreeBSD

This error was caused by rclone supplying an empty
`x-ms-blob-public-access:` header when creating a container for
private access, rather than omitting it completely.
This is a valid way of specifying containers should be private, but if
the storage account has the flag "Blob public access" unset then it
gives "409 Public access is not permitted on this storage account".
This patch fixes the problem by only supplying the header if the
access is set.
Fixes#6645
This patch implements --use-server-modtime for the Azureblob backend.
It does this by not reading the time from the metadata if the global
flag is set.
When the SDK was upgraded it started delivering metadata where the
keys were not in lower case as per the old SDK.
Rclone normalises the case of the keys for storage in the Object, but
the directory marker check was being done with the unnormalised keys
as it needs to be done before the Object is created.
This fixes the directory marker check to do a case insensitive compare
of the metadata keys.
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.
