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.
See #5734
- setup correct path encoding (fixes backend test FsEncoding)
- ignore range option if file is empty (fixes VFS test TestFileReadAtZeroLength)
- cleanup stray files left after failed upload (fixes test FsPutError)
- rebase code on master, adapt backend for rclone context passing
- translate Siad errors to rclone native FS errors in sia errorHandler
- TestSia: return proper backend options from the script
- TestSia: use uptodate AntFarm image, nebulouslabs/siaantfarm is stale
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.

This reverts commit
dc06973796 Revert "s3: use rclone's low level retries instead of AWS SDK to fix listing retries"
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.
Tested on integration test server with:
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
compared to accessing the file directly from S3. So added a download
URL advanced option, which when set downloads the file using it.
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
slow md5 but never reported this fact in features.
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.

Before this change, when uploading to a crypt, the ObjectInfo
accidentally used the encrypted size, not the unencrypted size when
--crypt-no-data-encryption was set.
Fixes#5498
In presence of no_data_encryption the Crypt's Put method used to over-optimize
and returned base object. This patch makes it return Crypt-wrapped object now.
Fixes#5498
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
message would then be something like:
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.
Fixes#5632
This was started in
3626f10f26 pcloud: add sha256 support - fixes#5496
But this support turned out to be incomplete and caused the
integration tests to fail.
After updating rclone's dependencies these tests started failing on
windows/386

The failures look like this. The root cause is unknown. The `Wait(n=1)
would exceed context deadline` errors come from golang.org/x/time/rate
but it isn't clear what is calling them.
