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.
- add a directory to the optional Purge interface
- fix up all the backends
- add an additional integration test to test for the feature
- use the new feature in operations.Purge
Many of the backends had been prepared in advance for this so the
change was trivial for them.
Before this change, for some operations, eg rcat or copyto (of a file)
rclone would attempt to create the container when using a SAS URL
limited to a container.
After this change we assume the container does not need creating when
using a container SAS URL.

According to Microsoft support this error can be caused by
> A timing/concurrency issue where the PUT operations are happening
> about the same time for a single blob. The Put Block List operation
> writes a blob by specifying the list of block IDs that make up the
> blob. In order to be written as part of a blob, a block must have
> been successfully written to the server in a prior Put Block
> operation.

- change the interface of listBuckets() removing dir parameter and adding context
- add makeBucket() and use in place of Mkdir("")
- this fixes some corner cases in Copy/Update
- mark all the listed buckets OK in ListR
Thanks to @yparitcher for the review.
* 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
- 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.
This enables MD5 checksum calculation and publication when uploading file above the "Cutoff" limit.
It was explictely ignored in case of multi-block (a.k.a. multipart) uploads to Azure Blob Storage.
Make the pacer package more flexible by extracting the pace calculation
functions into a separate interface. This also allows to move features
that require the fs package like logging and custom errors into the fs
package.
Also add a RetryAfterError sentinel error that can be used to signal a
desired retry time to the Calculator.
Before this change azureblob would attempt to create already existing
containers. This causes problems with limited permissions keys.
This change checks the container exists before trying to create it in
the same way the s3 backend does. This uses no more requests in the
usual case of the container existing.
See: https://forum.rclone.org/t/copying-individual-files-to-azure-blob-storage/8397
When a container is deleted, a container with the same name cannot be
created for at least 30 seconds; the container may not be available
for more than 30 seconds if the service is still processing the
request.
We sleep so that we wait at most 60 seconds. This is mostly useful in
the integration tests where containers get deleted and remade
immediately.
Before this change Rmdir would check the root rather than the
directory specified for being empty and return "directory not empty"
when it shouldn't have done.
Until https://github.com/Azure/azure-storage-blob-go/pull/75 is merged
the SDK can't upload a single blob of exactly the chunk size, so
upload files of this size with a multpart upload as a work around.
The previous fix for this 6a773289e7 turned out to cause problems
uploading files with maximum chunk size so needed to be redone.
Fixes#2653
This unifies the 3 methods of reading config
* command line
* environment variable
* config file
And allows them all to be configured in all places. This is done by
making the []fs.Option in the backend registration be the master
source of what the backend options are.
The backend changes are:
* Use the new configmap.Mapper parameter
* Use configstruct to parse it into an Options struct
* Add all config to []fs.Option including defaults and help
* Remove all uses of pflag
* Remove all uses of config.FileGet
This change includes removing older azureblob storage SDK, and getting
parity to existing code with latest blob storage SDK.
This change is also pre-req for addressing #2091
In a typical rclone copy to a bucket/container based remote, before
this change we were doing a list, followed by a HEAD of the bucket to
check it existed before doing the copy. The fact the list succeeded
means the bucket exists so mark it OK at that point.
Issue #1421
