Existing version did save username in config, but only when entering the custom
device/mountpoint sequence in config. Regardless of that, it did always look up the
username at startup with an api request.
This commit improves it so that the username will always be stored in config,
and when using standard authentication it picks it from the login token instead of
requesting it from the remote api, and also in fs constructor it picks it from config
instead of requesting it from remote api (again).
The SDK doesn't wrap errors in a Go standard way so they can't be
unwrapped and tested for - eg fatal error.
The code looks for a Serialization or RequestError and returns the
unwrapped underlying error if possible.
This fixes the fs/operations integration tests checking for fatal
errors being returned.
In this commit
e5974ac4b0 s3: use PutObject from the aws SDK to upload single part objects
rclone was made to upload objects to s3 using PUT requests rather than
using signed uploads.
However this change missed the fact that there is a supported way to
do this in the SDK using the SetStreamingBody method on the Request.
This therefore reverts a lot of the previous commit to do with making
an unsigned connection and other complication and uses the SDK
facility.
Before this fix GetFreeSpace returned math.MaxInt64 for remotes which
don't support reading free space, however this is used in various
comparison routines as a too large value, meaning that remotes of size
math.MaxInt64 were never being selected.
This fixes GetFreeSpace to return math.MaxInt64 - 1 so then can be selected.
It also fixes GetUsedSpace the same way however as the default for not
supported was 0 this was very unlikely to have ever caused a problem.
By default, rclone always requests read and write permissions. No matter what settings you configure in the AAD application. This option allows to explicitly request readonly permissions
Migrated read only option to access scope option and set disable_site_permission option to hidden.
Windows shells like cmd and powershell needs to use different quoting/escaping
of strings and paths than the unix shell, and also absolute paths must be fixed
by removing leading slash that the POSIX formatted paths have
(e.g. /C:/Users does not work in shell, it must be converted to C:/Users).
Tries to autodetect shell type (cmd, powershell, unix) on first use.
Implemented default builtin powershell functions for hashsum and about when remote
shell is powershell.

rclone backend drives -o config drive:
So that it also emits a config section called `AllDrives` which uses
the combine backend to make a backend which combines all the shared
drives into one.
It also makes sure that all the shared drive names are valid rclone
config names, deduplicating if necessary.
Fixes#4506
Before this change, if an object compressed with "Content-Encoding:
gzip" was downloaded, a length and hash mismatch would occur since the
as the go runtime automatically decompressed the object on download.
This change erases the length and hash on compressed objects so they
can be downloaded successfully, at the cost of not being able to check
the length or the hash of the downloaded object.
This also adds the --gcs-download-compressed flag to allow the
compressed files to be downloaded as-is providing compressed objects
with intact size and hash information.
Fixes#2658
Before this fix, if uploading to a union consisting of all bucket
based remotes (eg s3), uploads failed with:
Failed to copy: object not found
This was because the union backend was relying on parent directories
being created to work out which files to upload. If all the upstreams
were bucket based backends which can't hold empty directories, no
directories were created and the upload failed.
This fixes the problem by returning the upstreams used when creating
the directory for the upload, rather than searching for them again
after they've been created.
This will also make the union backend a little more efficient.

The "relative" argument was missing when Put'ing a file. This
sets an incorrect object entry in the cache, leading to the file being
unreadable when using mount functionality.
Fixes#6151
Before this change rclone used presigned requests to upload single
part objects. This was because of a limitation in the SDK which didn't
allow non seekable io.Readers to be passed in.
This is incompatible with some S3 backends, and rclone wasn't adding
the `X-Amz-Content-Sha256: UNSIGNED-PAYLOAD` header which was
incompatible with other S3 backends.
The SDK now allows for this so rclone can use PutObject directly.
This sets the `X-Amz-Content-Sha256: UNSIGNED-PAYLOAD` flag on the PUT
request. However rclone will add a `Content-Md5` header if at all
possible so the body data is still protected.
Note that the old behaviour can still be configured if required with
the `use_presigned_request` config parameter.
Fixes#5422
Uses b2_list_file_versions to retrieve all file versions, and returns
the one that was active at the specified time
This is especially useful in combination with other backup tools, such
as restic, which may use rclone as a backend.
Jottacloud have several different apis and endpoints using a mix of different
timestamp formats. In existing code the list operation (after the recent liststream
implementation) uses format from golang's time.RFC3339 constant. Uploads (using the
allocate api) uses format from a hard coded constant with value identical to golang's
time.RFC3339. And then we have the classic JFS time format, which is similar to RFC3339
but not identical, using a different constant. Also the naming is a bit confusing,
since the term api is used both as a generic term and also as a reference to the
newer format used in the api subdomain where the allocate endpoint is located.
This commit refactors these things a bit.
Now using the utility function for deduplication that was newly implemented to
fix an issue with server-side copy. This function uses the original, and generic,
"jfs" api (and its "cphash" feature), instead of the newer "allocate" api dedicated
for uploads. Both apis support similar deduplication functionaly that we rely on for
the SetModTime operation. One advantage of using the jfs variant is that the allocate
api is specialized for uploads, an initial request performs modtime-only changes and
deduplication if possible but if not possible it creates an incomplete file revision
and returns a special url to be used with a following request to upload missing content.
In the SetModTime function we only sent the first request, using metadata from existing
remote file but different timestamps, which lead to a modtime-only change. If, for some
reason, this should fail it would leave the incomplete revision behind. Probably not
a problem, but the jfs implementation used with this commit is simpler and
a more "standalone" request which either succeeds or fails without expecting additional
requests.
A strange feature (probably bug) in the api used by the server-side copy implementation
in Jottacloud backend is that if the destination file is in trash, the copy request
succeeds but the destination will still be in trash! When this situation occurs in
rclone, the copy command will fail with "Failed to copy: object not found" because
rclone verifies that the file info in the response from the copy request is valid,
and since it is marked as deleted it is treated as invalid.
This commit works around this problem by looking for this situation in the response
from the copy operation, and send an additional request to a built-in deduplication
endpoint that will restore the file from trash.
Fixes#6112
The existing code in rclone set the value "offline_access+openid",
when encoded in body it will become "offline_access%2Bopenid". I think
this is wrong. Probably an artifact of "double urlencoding" mixup -
either in rclone or in the jottacloud cli tool version it was sniffed
from? It does work, though. The token received will have scopes "email
offline_access" in it, and the same is true if I change to only
sending "offline_access" as scope.
If a proper space delimited list of "offline_access openid"
is used in the request, the response also includes openid scope:
"openid email offline_access". I think this is more correct and this
patch implements this.
See: #6107
Adds a configuration option to the GCS backend to allow skipping the
check if a bucket exists before copying an object to it, much like
f406dbb added for S3.
Before this change the cache backend was passing -1 into
rate.NewLimiter to mean unlimited transactions per second.
In a recent update this immediately returns a rate limit error as
might be expected.
This patch uses rate.Inf as indicated by the docs to signal no limits
are required.
Before this change the 206 responses from putio Range requests were being
returned as errors.
This change checks for 200 and 206 in the GET response now.
Before this fix, rclone retries chunks of multipart uploads. However
if they had been partially received dropbox would reply with an
incorrect_offset error which rclone was ignoring.
This patch parses the new offset from the error response and uses it
to adjust the data that rclone sends so it is the same as what dropbox
is expecting.
See: https://forum.rclone.org/t/dropbox-rate-limiting-for-upload/29779
This commit switches Google Cloud Storage from the drive pacer to the
s3 pacer. The main difference between them is that the s3 pacer does
not limit transactions in the non-error case. This is appropriate for
a cloud storage backend where you pay for each transaction.
Before this fix `NewObject` could return a wrapped `fs.Object(nil)`
which caused a crash. This was caused by `wrapObject` returning a
`nil` `*Object` which was cast into an `fs.Object`.
This changes the interface of `wrapObject` so it returns an
`fs.Object` instead of a `*Object` and an error which must be checked.
This forces the callers to return a `nil` object rather than an
`fs.Object(nil)`.

Having a replace directive in go.mod causes "go get

This is apparently how the Go team want go.mod to work, so this commit
hard forks github.com/jlaffaye/ftp into github.com/rclone/ftp so we
can remove the `replace` directive from the go.mod file.

Before this change rclone send pre-1970 timestamps as negative
numbers. pCloud ignores these and sets them as todays date.
This change sends the timestamps as unsigned 64 bit integers (which is
how the binary protocol sends them) and pCloud accepts the (actually
negative) timestamp like this.
Before this change the new multipart upload ETag checking code was
failing in the integration tests with Alibaba OSS.
Apparently Alibaba calculate the ETag in a different way to AWS.
This introduces a new provider quirk with a flag to disable the
checking of the ETag for multipart uploads.
Mulpart Etag checking has been enabled for all providers that we can
test for and work, and left disabled for the others.
Before this rclone ignored the ETag on multipart uploads which missed
an opportunity for a whole file integrity check.
This adds that check which means that we now check even harder that
multipart uploads have arrived properly.
See #5993
Before this change `rclone about swift:container` would show aggregate
info about all the containers, not just the one in use.
This causes a problem if container listing is disabled (for example in
the Blomp service).
This fix makes `rclone about swift:container` show only the info about
the given `container`. If aggregate info about all the containers is
required then use `rclone about swift:`.

Before this change, rclone supported authorizing for remote systems by
going to a URL and cutting and pasting a token from Google. This is
known as the OAuth out-of-band (oob) flow.
This, while very convenient for users, has been shown to be insecure
and has been deprecated by Google.
https://developers.googleblog.com/2022/02/making-oauth-flows-safer.html#disallowed-oob
> OAuth out-of-band (OOB) is a legacy flow developed to support native
> clients which do not have a redirect URI like web apps to accept the
> credentials after a user approves an OAuth consent request. The OOB
> flow poses a remote phishing risk and clients must migrate to an

This change disables that flow, and forces the user to use the
redirect URL flow. (This is the flow used already for local configs.)
In practice this will mean that instead of cutting and pasting a token
for remote config, it will be necessary to run "rclone authorize"
instead. This is how all the other OAuth backends work so it is a well
tested code path.

Before this change a multipart upload with the --no-head flag returned
the MD5SUM as a base64 string rather than a Hex string as the rest of
rclone was expecting.
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

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.
Before this fix if a file was updated, but to the same length and
timestamp then the local backend would return the wrong (cached)
hashes for the object.
This happens regularly on a crypted local disk mount when the VFS
thinks files have been changed but actually their contents are
identical to that written previously. This is because when files are
uploaded their nonce changes so the contents of the file changes but
the timestamp and size remain the same because the file didn't
actually change.
This causes errors like this:
ERROR: file: Failed to copy: corrupted on transfer: md5 crypted
hash differ "X" vs "Y"
This turned out to be because the local backend wasn't clearing its
cache of hashes when the file was updated.
This fix clears the hash cache for Update and Remove.
It also puts a src and destination in the crypt message to make future
debugging easier.

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.
See: https://forum.rclone.org/t/performance-of-rclone-vs-azcopy/27437/9
Previously only the fs being checked on gets passed to
GetModifyWindow(). However, in most tests, the test files are
generated in the local fs and transferred to the remote fs. So the
local fs time precision has to be taken into account.
This meant that on Windows the time tests failed because the
local fs has a time precision of 100ns. Checking remote items uploaded
from local fs on Windows also requires a modify window of 100ns.
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.
This removes the checks against the provider throughout the code and
puts them into a single setQuirks function for easy maintenance when
adding a new provider.
It also updates the quirks with the results of testing against
backends we have access to.
This also adds a list_url_encode parameter so that quirk can be
manually set.
This implements a quirks system for providers and notes which
providers we have tested to support ListObjectsV2.
For those providers which don't support ListObjectsV2 we use the
original ListObjects call.
The API doesn't seem to accept a value of "0" any more for the root

However some object storage systems, notably Ceph, don't return a

However due to this commit from 2014, released in v1.18, the
setMetaData function was not ignoring the size as it should have done.

Before this change the `shared_credentials_file` config option was
being ignored.
The correct value is passed into the SDK but it only sets the
credentials in the default provider. Unfortunately we wipe the default
provider in order to install our own chain if env_auth is true.
This patch restores the shared credentials file in the session
options, exactly the same as how we restore the profile.
Original fix:

This patch reverts this commit
1605f9e14d s3: Fix shared_credentials_file auth
It unfortunately had the side effect of making the s3 SDK ignore the
config in our custom chain and use the default provider. This means
that advanced auth was being ignored such as --s3-profile with
role_arn.

The API has changed in the directory move call JSON response from

This patch allows the TaskID to be an integer or a string in the JSON
response and keeps it internally as a string like before.
Before this change the backoff for the error_background error was 6
seconds. This means that if it wasn't resolved in 60 seconds (with the
default 10 low level retries) then an error was reported.
This error was being reported frequently in the integration tests, so
is likely affecting real users too.
This patch changes the backoff into an exponential backoff
1,2,4,8...1024 seconds to make sure we wait long enough for the
background operation to complete.

Which in turn reverted
5470d34740 "backend/s3: use low-level-retries as the number of SDK retries"
So we are back where we started.
It then modifies it to set the AWS SDK to `--low-level-retries`
retries, but set the rclone retries to 2 so that directory listings
can be retried.
Before this change the cleanup routine exited on the first deletion
error.
This change counts any errors on deletion and exits when the iteration
is complete with an error showing the number of deletion failures.
Deletion failures will be logged.
Before this change we uses limit/offset paging for directories in the
main directory listing routine and in the trash cleanup listing.
This switches to the new scheme of limit/marker which is more reliable
on a directory which is continuously changing. It has the disadvantage
that it doesn't tell us the total number of items available, however
that wasn't information rclone uses.
This changes the interface to NewObject so that if NewObject is called
on a directory then it should return fs.ErrorIsDir if possible without
doing any extra work, otherwise fs.ErrorObjectNotFound.

go run integration-test.go -tests backend -run TestIntegration/FsMkdir/FsPutFiles/FsNewObjectDir -branch fix-stat -maxtries 1
The egress charges while using a CloudFront CDN url is cheaper when

Before this patch the md5all option would skip creating metadata with
hashsum if base filesystem provided md5, in hope to pass it through.
However, if base hash is slow (for example on local fs), chunker passed

This patch makes chunker snapshot base hashsum in metadata when md5all is
set and base hashsum is slow since chunker was intended to provide only
instant hashsums from the start.

I discovered that `rclone` always upload in chunks of 16MiB whenever
uploading a file smaller than `--drive-upload-cutoff`. This is
undesirable since the purpose of the flag `--drive-upload-cutoff` is
to *prevent* chunking below a certain file size.
I realized that it wasn't `rclone` forcing the 16MiB chunks. The
`google-api-go-client` forces a chunk size default of
[`googleapi.DefaultUploadChunkSize`](32bf29c2e1/googleapi/googleapi.go (L55-L57))
bytes for resumable type uploads. This means that all requests that
use `*drive.Service` directly for upload without specifying a
`googleapi.ChunkSize` will be forced to use a *`resumable`*
`uploadType` (rather than `multipart`) for files less than
`googleapi.DefaultUploadChunkSize`. This is also noted directly in the
Drive API client documentation [here](https://pkg.go.dev/google.golang.org/api/drive/v3@v0.44.0#FilesUpdateCall.Media).
This fixes the problem by passing `googleapi.ChunkSize(0)` to
`Media()` method calls, which is the only way to disable chunking
completely. This is mentioned in the API docs
[here](https://pkg.go.dev/google.golang.org/api/googleapi@v0.44.0#ChunkSize).
The other alternative would be to pass
`googleapi.ChunkSize(f.opt.ChunkSize)` -- however, I'm *strongly* in
favor of *not* doing this for performance reasons. By not explicitly
passing a `googleapi.ChunkSize(0)`, we effectively allow
[`PrepareUpload()`](https://pkg.go.dev/google.golang.org/api/internal/gensupport@v0.44.0#PrepareUpload)
to create a
[`NewMediaBuffer`](https://pkg.go.dev/google.golang.org/api/internal/gensupport@v0.44.0#NewMediaBuffer)
that copies the original `io.Reader` passed to `Media()` in order to
check that its size is less than `ChunkSize`, which will unnecessarily
consume time and memory.
`minChunkSize` is also changed to be `googleapi.MinUploadChunkSize`,
as it is something specified we have no control over.
Google Drive API allows for clauses like "modifiedTime > '2012-06-04T12:00:00'"
in the query param, so the filter flags --max-age and --min-age can be applied
directly at the directory listing phase rather than in a filter.
This is extremely helpful when we want to do an incremental backup of a remote
drive with many files but the number of recently changed file is small.

This replaces built-in os.MkdirAll with a patched version that stops the recursion
when reaching the volume part of the path. The original version would continue recursion,
and for extended length paths end up with \\? as the top-level directory, and the error

mkdir \\?: The filename, directory name, or volume label syntax is incorrect.
Before this change the union's feature flags were a strict AND of the
underlying remotes. This means that a union of a local disk (which can
Move but not Copy) and a bucket based remote (which can Copy but not
Move) could neither Move nor Copy.
This fix advertises Move in the union if all the remotes can Move or
Copy. It also implements Move as Copy+Delete (like rclone does
normally) if the underlying union does not support Move.
This enables renames to work with unions of local disk and bucket
based remotes expected.

94dbfa4ea fs: change Config callback into state based callback #3455
This passed the password as a temporary config parameter but forgot to
reveal it in the API call.
At some point some google docs files started having sizes returned in
their listing information.
This then caused rclone to treat the docs as files which caused
downloads to fail.
The API docs now state that google docs may have sizes (whereas I'm
pretty sure it didn't earlier).
This fix removes the check for size, so google docs are identified
solely by not having an MD5 checksum.
This change fixes the bug described below:
if a file is removed while the local backend List() runs,
the call will flag an accounting error.
The bug manifests itself if local backend is the Sync target
due to intrinsic concurrency.
The odds to hit this bug depend on --checkers and --transfers.
Chunker over local backend is affected even more because
updating a composite object with a smaller size content
translates into removing chunks on the underlying file system
and involves a number of List() calls.
- 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.

It was discovered on some Android systems, the stat size of a symlink

There are enough exceptions to the size of readlink being different to
the size of stat that this patch now always does readlink to work out
the size of a symlink.
Since symlinks are relatively uncommon this shouldn't affect
performance too much and will mean that the size is always correct.

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.
v1.4.6 of uplink allows us to do a negative offset from the end of the
file. This removes a round trip when requesting the last N bytes of a
file.
Previous to v1.4.6 of uplink it wasn't possible to do a negative offset
on download. This meant that to fulfill the semantics of http range
headers it was necessary to first fetch the size of the object via a
stat call and compute absolute offset and length.
Restructuring of config code in v1.55 resulted in config
file being loaded early at process startup. If configuration
file is encrypted this means user will need to supply the password,
even when running commands that does not use config.
This also lead to an issue where mount with --deamon failed to
decrypt the config file when it had to prompt user for passord.

Including the bucket name as part of the `fileNamePrefix` passed to
`b2_get_download_authorization` results in a link valid for objects that
have the bucket name as part of the object path; e.g.,
rclone link :b2:some-bucket/some-file
would result in a public link valid for the object
`some-bucket/some-file` in the `some-bucket` bucket (in rclone-remote
parlance, `:b2:some-bucket/some-bucket/some-file`). This will almost
certainly result in a broken link.
The B2 docs don't explicitly specify this behavior, but the example
given for `fileNamePrefix` provides some clarification.
See https://www.backblaze.com/b2/docs/b2_get_download_authorization.html.

15d19131bd s3: use aws web identity role provider
This code no longer works because it doesn't initialise the
tokenFetcher - leading to a nil pointer crash.
The proper way to initialise this is with the
NewWebIdentityCredentials but it isn't clear where to get the other
parameters: roleARN, roleSessionName, path.
In the linked issue a user reports rclone working with EKS anyway, so
perhaps this code is no longer needed.
If it is needed, hopefully someone who knows AWS better will come
along and fix it!

Betweeen rclone v1.54 and v1.55 there was an approx 3x performance
regression when transferring to distant SFTP servers (in particular
rsync.net).
This turned out to be due to the library github.com/pkg/sftp rclone
uses. Concurrent writes used to be enabled in this library by default
(for v1.12.0 as used in rclone v1.54) but they are no longer enabled
(for v1.13.0 as used in rclone v1.55) for safety reasons and it is
necessary to enable them specifically.
The safety concerns are due to the uncertainty as to whether writes
come in order and whether a half completed file might have holes in
it. This isn't a problem for rclone since a) it doesn't restart
uploads and b) it has a post-transfer checksum test.
This change introduces a new flag `--sftp-disable-concurrent-writes`
to control the feature which defaults to false, meaning that
concurrent writes are enabled as in v1.54.
However this isn't quite enough to fix the problem as the sftp library
needs to be able to sniff the size of the stream from the reader
passed in, so this also adds a `Size` interface to the reader to
enable this. This involved a patch to the library.
The library was reverted to v1.12.0 for v1.55.1 - this patch installs
v1.13.0+master to fix the Size interface problem.

Before this change, rclone checked to see if an object existed before
doing an upload by listing the destination directory. This was very
inefficient, especially with large directories.
After this change rclone uses the pre upload check API call which
checks to see if it is OK to upload an object, and also returns the ID
of an existing object which saves rclone having to do a directory
listing.
OneDrive randomly returns the error message: "InvalidAuthenticationToken: Unable to initialize RPS". These unexpected errors typically caused the entire rclone command to fail.
This work around recognizes these errors and marks them for a low level retry, that mostly succeeds. This will make rclone commands complete without being noticeable affected.
Fixes: #5270
With the file version format standardized in lib/version, `crypt` can
now treat the version strings separately from the encrypted/decrypted
file names. This allows --b2-versions to work with `crypt`.

Before this change rclone would auth over https even when the server
was configured with http.
Authing over http obviously isn't ideal, however this type of server
is on-premise and doesn't work over https.
PR #4266 modified ftpConnection to make ftp library into using
a custom dial function which is QoS aware and takes care of TLS.
However the ServerConn.Login function from the ftp library also needs
TLS config passed explicitly as a trigger for sending PSBZ and PROT
options to FTP server. This was not taken care of resulting in
failure to connect via FTP with implicit TLS.
This PR fixes that.

In
a3fcadddc8 sftp: close idle connections after --sftp-idle-timeout (1m by default)
Idle SFTP connections were closed after 1 minute. However due to the
way SSH multiplexes connections over a single SSH connection this
meant that if uploads or downloads went on for more than one minute
they failed with "EOF errors" as their underlying connection was
closed.
This fixes the problem by not clearing idle connections if there are
any transfers in progress.
Fixes#5197

713f8f357d sftp: fix "file not found" errors for read once servers
Reverting this commit triples the performance to a far away sftp server.

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.
When reading files from B2 via cloudflare using --b2-download-url
cloudflare strips the Content-Length headers (presumably so it can
inject stuff into the body).
This caused rclone to think the file was corrupted as the length
didn't match.
The patch uses the old length read from the listing if there is no
Content-Length.

f17d7c0012 union: refactor to use fspath.SplitFs instead of fs.ParseRemote #4996
This patch fixes it.
Box recently changed their API, changing the case of returned API items
> On May 10th, 2021, as part of our continued infrastructure upgrade,

Rclone was reading the raw headers from the `http.Header` and not
using the `Get` accessor method which meant that it was sensitive to
case changes.
This fixes the problem by using the `Get` accessor method.

If you exceed rate limits, dropbox tells you to wait for 300 seconds -
this is rather a long time for the user to be waiting for rclone to
finish, so emit a NOTICE level log instead of a DEBUG.
Some sftp servers don't allow the user to access the file after upload.
In this case the error message indicates that using
--sftp-set-modtime=false would fix the problem. However it doesn't
because SetModTime does a stat call which can't be disabled.
Update SetModTime failed: SetModTime stat failed: object not found
After upload this patch checks for an `object not found` error if
set_modtime == false and ignores it, returning the expected size of
the object instead.
It also makes SetModTime do nothing if set_modtime = false

These were added by accident in
d9959b0271 drive: pass context on to drive SDK - this will help with cancellation
Which added lots of new Context() calls but duplicated some existing
ones.
Before this we just failed if the ftp connection or login failed.
This change adds a pacer just for the ftp connect and retries if the
connection failed to Dial or the login returns a 421 error.
This is implemented as a state machine parser so it can emit sensible
error messages.
It does not use the connection strings elsewhere in rclone yet - see
subsequent commits.
An optional fuzzer is implemented for the Parse function.
Before this change, when using an all create method with one of the
upstreams being read only, if there was an existing file on the read
only remote, it was impossible to update it.
This change detects that situation and creates the file on a
read/write upstream. This file will shadow the file on the read/only
upstream. If it is deleted the read only upstream file will be visible
again.
Fixes#4929
Before this fix using the epff policy could double close a channel.
The fix refactors the code to make that impossible and cancels any
running queries when the first query is found.
