Amazon S3 is built to handle different kinds of workloads.
In rare cases where S3 is not able to scale for whatever reason users
will face status 500 errors.
Main mechanism for handling these errors are retries.
Amount of needed retries varies for each different use case.
This change is making retries for s3 backend configurable by using
--low-level-retries option.
Currently each multipart upload allocated his own buffers, which after
file upload was garbaged. Next files couldn't leverage already allocated
memory which resulted in inefficent memory management. This change
introduces backend memory pool keeping memory chunks which can be
used during object operations.
Fixes#3967
The error code 500 Internal Error indicates that Amazon S3 is unable to handle the request at that time. The error code 503 Slow Down typically indicates that the requests to the S3 bucket are very high, exceeding the request rates described in Request Rate and Performance Guidelines.
Because Amazon S3 is a distributed service, a very small percentage of 5xx errors are expected during normal use of the service. All requests that return 5xx errors from Amazon S3 can and should be retried, so we recommend that applications making requests to Amazon S3 have a fault-tolerance mechanism to recover from these errors.

This removes the unused functions run.writeRemoteRandomBytes() run.writeObjectRandomBytes() run.listPath() Directory.parentRemote() and Persistent.dumpRoot().
Before this change, when uploading multipart files, onedrive would
sometimes return an unexpected 416 error and rclone would abort the
transfer.
This is usually after a 500 error which caused rclone to do a retry.
This change checks the upload position on a 416 error and works how
much of the current chunk to skip, then retries (or skips) the current
chunk as appropriate.
If the position is before the current chunk or after the current chunk
then rclone will abort the transfer.

This hides:
- "use_created_date"
- "use_shared_date"
- "size_as_quota"
from the configurator (rclone config) as they interfere with normal
operations and shouldn't be set in a backend config.
They can still be put in the config file by hand and will still work
as variables, etc.
This adds some more docs to "size_as_quota" also.
Fixes#3912
Before this change we used non multipart uploads for files of unknown
size (streaming and uploads in mount). This is slower and less
reliable and is not recommended by Google for files smaller than 5MB.
After this change we use multipart resumable uploads for all files of
unknown length. This will use an extra transaction so is less
efficient for files under the chunk size, however the natural
buffering in the operations.Rcat call specified by
`--streaming-upload-cutoff` will overcome this.

This error started happening after updating golang/x/crypto which was
done as a side effect of:
3801b8109 vendor: update termbox-go to fix ncdu command on FreeBSD
This turned out to be a deliberate policy of making
ssh.ParsePrivateKeyWithPassphrase fail if the passphrase was empty.
See: https://go-review.googlesource.com/c/crypto/+/207599
This fix calls ssh.ParsePrivateKey if the passphrase is empty and
ssh.ParsePrivateKeyWithPassphrase otherwise which fixes the problem.
If the --drive-stop-on-upload-limit flag is in effect this checks the
error string from Google Drive to see if it is the error you get when
you've breached your 750GB a day limit.
If so then it turns this error into a Fatal error which should stop
the sync.
Fixes#3857
In listings if the ID `appDataFolder` is used to list a directory the
parents of the items returned have the actual ID instead the alias
`appDataFolder`. This confused the ListR routine into ignoring all
these items.
This change makes the listing routine accept all parent IDs returned
if there was only one ID in the query. This fixes the `appDataFolder`
problem. This means we are relying on Google Drive to only return the
items we asked for which is probably OK.
Fixes#3851
The S3 ListObject API returns paginated bucket listings, with
"MaxKeys" items for each GET call.
The default value is 1000 entries, but for buckets with millions of
objects it might make sense to request more elements per request, if
the backend supports it. This commit adds a "list_chunk" option for
the user to specify a lower or higher value.
This commit does not add safe guards around this value - if a user
decides to request a too large list, it might result in connection
timeouts (on the server or client).
In AWS S3, there is a fixed limit of 1000, some other services might
have one too. In Ceph, this can be configured in RadosGW.
Before this patch we were failing to URL decode the NextMarker when
url encoding was used for the listing.
The result of this was duplicated listings entries for directories
with >1000 entries where the NextMarker was a file containing a space.
Before this change we used the same (relatively low limits) for server
side copy as we did for multipart uploads. It doesn't make sense to
use the same limits since no data is being downloaded or uploaded for
a server side copy.
This change introduces a new parameter --s3-copy-cutoff to control
when the switch from single to multipart server size copy happens and
defaults it to the maximum 5GB.
This makes server side copies much more efficient.
It also fixes the erroneous error when trying to set the modification
time of a file bigger than 5GB.
See #3778
Before this change multipart copies were giving the error
Range specified is not valid for source object of size
This was due to an off by one error in the range source introduced in
7b1274e29a "s3: support for multipart copy"
Before this change rclone used "Authorization: BEARER token". However
according the the RFC this should be "Bearer"
https://tools.ietf.org/html/rfc6750#section-2.1
This changes it to "Authorization: Bearer token"
Fixes#3751 and interop with Salesforce Webdav server
When using nextcloud, before this change we only uploaded one of SHA1
or MD5 checksum in the OC-Checksum header with preference to SHA1 if
both were set.
This makes the MD5 checksums read as empty string which makes syncing
with checksums less useful than they should be as all the MD5
checksums are blank.
This change makes it so that we only upload the SHA1 to nextcloud.
The behaviour of owncloud is unchanged as owncloud uses the checksum
as an upload integrity check only and calculates its own checksums.
See: https://forum.rclone.org/t/how-to-specify-hash-method-to-checksum/13055
This also corrects the symlink detection logic to only check symlink
files. Previous to this it was checking all directories too which was
making it do more stat calls than was necessary.
Before this change we forgot to URL decode the X-Object-Manifest in a dynamic large object.
This problem was introduced by 2fe8285f89 "swift: reserve
segments of dynamic large object when delete objects in container what
was enabled versioning."
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 rclone used the team_drive ID as the root if set
even if the root_folder_id was set too.
This change uses the root_folder_id in preference over the team_drive
which restores the functionality.
This problem was introduced by ba7c2ac443Fixes#3742
We attempt to find the ID of the root folder by doing a GET on the
folder ID "root". With scope "drive.files" this fails with a 404
message.
After this change if we get the 404 message, we just carry on using
"root" as the root folder ID and we cache that for future lookups.
This means that changenotify messages will not work correctly in the
root folder but otherwise has minor consequences.

Before this change rclone would allow the user to stream (eg with
rclone mount, rclone rcat or uploading google photos or docs) 5TB
files. This meant that rclone allocated 4 * 525 MB buffers per
transfer which is way too much memory by default.
This change makes rclone use the configured chunk size for streamed
uploads. This is 5MB by default which means that rclone can stream
upload files up to 48GB by default staying below the 10,000 chunks
limit.
This can be increased with --s3-chunk-size if necessary.
If rclone detects that a file is being streamed to s3 it will make a
single NOTICE level log stating the limitation.
This fixes the enormous memory usage.
Fixes#3568
See: https://forum.rclone.org/t/how-much-memory-does-rclone-need/12743
Before this fix we neglected to add the shared drive ID to the request
when asking for an initial change notify token and this caused a lot
more results to be returned than was necessary.
When we changed recursive lists to use --fast-list by default this
broke listing with --drive-shared-with-me from the root.
This turned out to be an unwarranted assumption in the ListR code that
all items would have a parent folder that we had searched for - this
isn't true for shared with me items.
This was fixed when using --drive-shared-with-me to give items that
didn't have any parents a synthetic parent.
Fixes#3639
Before this change we used the id "root" as an alias for the root drive ID.
However this causes problems when we receive IDs back from drive which
are not in this format and have been expanded to their canonical ID.
This change looks up the ID "root" and stores it in the
"drive_folder_id" parameter in the config file.
This helps with
- Notifying changes at the root
- Files shared with me at the root
See #3639
Before this change when rclone was compiled with go1.13 it used HTTP/2
to contact drive by default.
This causes lockups and INTERNAL_ERRORs from the HTTP/2 code.
This is a workaround disabling the HTTP/2 code on an option.
It can be re-enabled with `--drive-disable-http2=false`
See #3631
Before this change we silently skipped uploads to dropbox of
disallowed file names. However this then caused "corrupted on
transfer" errors because the sizes were wrong.
After this change we return an no retry error which will mean that the
sync fails (as it should - not all files were uploaded) but no
unecessary retries happened.
