Currently rclone check supports matching two file trees by sizes and hashes.
This change adds support for SUM files produced by GNU utilities like sha1sum.
Fixes#1005
Note: checksum by default checks, hashsum by default prints sums.
New flag is named "--checkfile" but carries hash name.
Summary of introduced command forms:
```
rclone check sums.sha1 remote:path --checkfile sha1
rclone checksum sha1 sums.sha1 remote:path
rclone hashsum sha1 remote:path --checkfile sums.sha1
rclone sha1sum remote:path --checkfile sums.sha1
rclone md5sum remote:path --checkfile sums.md5
```
- Unify all hash names as lowercase alphanumerics without punctuation.
- Legacy names continue to work but disappear from docs, they can be depreciated or dropped later.
- Make rclone hashsum print supported hash list in case of wrong spelling.
- Update documentation.

Before this change when the context was cancelled (due to
--max-duration for example) this could deadlock when uploading
multipart uploads.
This change fixes the problem by introducing another go routine to
monitor the context and close the pipe with an error when the context
errors.
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.

This change makes dedupe recursively count elements in same-named directories
and make the largest one primary. This allows to minimize the amount of data
moved (or at least the amount of API calls) when dedupe merges them.
It also adds a new fs.Object interface `ParentIDer` with function `ParentID` and
implements it for the drive and opendrive backends. This function returns
parent directory ID for objects on filesystems that allow same-named dirs.
We use it to correctly count sizes of same-named directories.
Fixes#2568

This commit modifies the operations.hashSum function by adding an alternate code path. This code path is triggered by passing downloadFlag = True. When activated, rclone will download files from the remote and hash them locally. downloadFlag = False preserves the existing behavior of using the remote to retrieve the hash.
This commit modifies HashLister to support the new hashSum method as well as consolidating the roles of HashLister, HashListerBase64, Md5sum, and Sha1sum. The printing of hashes from the function defined in HashLister has been revised to work with --progress. There are light changes to operations.syncFprintf and cmd.startProgress for this.
The unit test operations_test.TestHashSums is modified to support this change and test the download functionality.
The command functions hashsum, md5sum, sha1sum, and dbhashsum are modified to support this change. A download flag has been added and an output-file flag has been added. The output-file flag writes hashes to a file instead of stdout to avoid the need to redirect stdout.
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.
Fix the copy and move operations that broke in 127f0fc when copying directly
to a remote without a specific destination.

Before this change we counted the final summary error as an error,
producing confusing log messages like:
Failed to check with 54 errors: last error was: 53 differences found
This change marks the summary error as already being counted, so the
error message becomes:
Failed to check with 53 errors: last error was: 53 differences found
This change also returns a listing failure in preference to a summary error.

Before this change rclone would emit the message
--checksum is in use but the source and destination have no hashes in common; falling back to --size-only
When the source or destination hash was missing as well as when the
source and destination had no hashes in common.
This first case is very confusing for users when the source and
destination do have a hash in common.
This change fixes that and makes sure the error message is not emitted
on missing hashes even when there is a hash in common.

Before ths fix --cutoff-mode soft and cautious would emit a Fatal
error which stopped the sync immediately.
This fix introduces a new error which is checked in the sync error
processing which stops the sync gracefully.
Fixes#4576
- 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.
This is preparation for getting the Accounting to check the context,
buf first we need to get it in place. Since this is one of those
changes that makes lots of noise, this is in a seperate commit.
This adds expire and unlink fields to the PublicLink interface.
This fixes up the affected backends and removes unlink parameters
where they are present.
Before this change if you specified --hash MD5 in rclone lsf it would
calculate all the hashes and just return the MD5 hash which was very
slow on the local backend.
Likewise specifying --hash on rclone lsjson was equally slow.
This change introduces the --hash-type flag (and corresponding
internal parameter) so that the hashes required can be selected in
lsjson.
This is used internally in lsf when the --hash parameter is selected
to speed up the hashing by only hashing with the one hash specified.
Fixes#4181
Before this change if there were two files with the same name and the
same ID in the same directory, dedupe would delete one of them but
since these are actually the same file (with the same ID) then both
files would be deleted leading to data loss.
This should never actually happen, however it did happen as part of a
bug introduced in rclone which was fixed by
dfc7215bf9 drive: fix duplicate items when using --drive-shared-with-me #4018
This change checks to see if any of the duplicates have the same ID
and if they do it refuses to delete them.
Before this change backends which introduce overhead (eg crypt) were
failing to upload the first file.
This change increases the threshold to 2k to allow the first file to
go through even with some overhead but the next file to definitely
fail.
Before this change we checked the transfer was out of range only
before the Read call. This means that we returned all the data to the
reader before declaring an error. This means that some backends wrote
the file even though an error was returned.
This fix checks the transfer after the Read as well, and chops the
excess characters off the read data if we are over the limit so that
we don't ever deliver all the data.
This fixes the tests introduced as part of 6f1766dd9e and #2672
on backends other than local.
Before this change the exit code for transfer limit exceeded was
incorrect. This was because the `resolveExitCode` function unwraps the
error thus reading the underlying error which is not the same as the
error it was comparing to (`ErrorMaxTransferLimitReached`).
This change fixes it by splitting the error definition in two so that
when the Fatal error is unwrapped we match against
`ErrorMaxTransferLimitReached` however when we return the error we
return `ErrorMaxTransferLimitReachedFatal`.
In bde0334bd8 "operations: fix setting the timestamp on Windows
for multithread copy" the test for multithread copy failed to take
into account the modify window of the remote under test.
Before this fix we attempted to set the modification time on the file
when it was open. This works fine on Linux but not on Windows. The
test was also incorrect testing the source file rather than the
destination file.
This closes the file before setting the modification time and fixes
the tests.
Fixes#3994
Before this changed we unconditionally fetched the MimeType. On Some
backends like s3 and swift this takes an extra transaction which meant
that `lsf` on those backends was needlessly slow.
This adds an internal option so `lsf` can declare whether it wants
MimeTypes or not depending on whether the user asked for them and an
external flag `--no-mimetype` for `lsjson`.
See: https://forum.rclone.org/t/reliably-setup-incremental-updates/14006/8
Statistics of ransfers which were interrupted are not cleared before
retry iteration. These transfers completed with over 100 percentage.
This change clears transfer accounting before next retry iteration is
done in order to keep numbers in track.
Fixes#3861
For few commands, RClone counts a error multiple times. This was fixed by
creating a new error type which keeps a flag to remember if the error has
already been counted or not. The CountError function now wraps the original
error eith the above new error type and returns it.
Before this change --update would transfer any file which was newer
than the destination regardless of whether it had changed or not.
This is needlessly wasteful of bandwidth.
After this change --update will only transfer files if they are newer
**and** they are different (checked with checksum and size).
