Each upload allocated a fresh chunk-sized buffer (10 MiB by default)
regardless of the file size, so bulk transfers of many files churned
allocations and GC.
Buffer chunks with multipart.NewRW instead so chunk memory is reused
across uploads and is part of rclone's central memory management. The
pool.RW is seekable, so the existing rewind on retry carries over.
The body goes through lib/rest which already wraps it so the transport
can't close the pool buffer. The upload loop closes it after every
chunk, on error paths included. A source which ends before the
declared size is now reported as a short read before the chunk is sent
rather than as an incomplete write afterwards.
The FsPutRetry integration test covers the retry of a failed upload
request and checks the buffers are returned to the pool.
Objects looked up by name used the /folder/itembyname.json endpoint
which does not return the file's MD5 hash, so NewObject returned
objects with no hash. Read the metadata with /file/info.json (which
does return the hash) instead, using itembyname only to find the file
id when it isn't known.
Copy and Move returned objects with only the id and size filled in,
leaving the modtime and hash empty, and SetModTime kept nanosecond
precision in memory while the server stores seconds. These made the
returned objects differ from a fresh listing of the same objects.
This commit modernizes Go usage. This was done with:
go run golang.org/x/tools/gopls/internal/analysis/modernize/cmd/modernize@latest -fix -test ./...
Then files needed to be `go fmt`ed and a few comments needed to be
restored.
The modernizations include replacing
- if/else conditional assignment by a call to the built-in min or max functions added in go1.21
- sort.Slice(x, func(i, j int) bool) { return s[i] < s[j] } by a call to slices.Sort(s), added in go1.21
- interface{} by the 'any' type added in go1.18
- append([]T(nil), s...) by slices.Clone(s) or slices.Concat(s), added in go1.21
- loop around an m[k]=v map update by a call to one of the Collect, Copy, Clone, or Insert functions from the maps package, added in go1.21
- []byte(fmt.Sprintf...) by fmt.Appendf(nil, ...), added in go1.19
- append(s[:i], s[i+1]...) by slices.Delete(s, i, i+1), added in go1.21
- a 3-clause for i := 0; i < n; i++ {} loop by for i := range n {}, added in go1.22
Before this change, moving (renaming) a file or folder to a different name
within the same parent directory would fail, due to using the wrong API
operation ("/file/move_copy.json" and "/folder/move_copy.json", instead of the
separate "/file/rename.json" and "/folder/rename.json" that opendrive has for
this purpose.)
After this change, Move and DirMove check whether the move is within the same
parent dir. If so, "rename" is used. If not, "move_copy" is used, like before.
Sometimes opendrive reports "403 Folder is already deleted" on
directories which should exist.
This might be a bug in opendrive or in rclone however we work-around
here sufficient to get the tests passing.
This introduces a new fs.Option flag, Sensitive and uses this along
with IsPassword to redact the info in the config file for support
purposes.
It adds this flag into backends where appropriate. It was necessary to
add oauthutil.SharedOptions to some backends as they were missing
them.
Fixes#5209
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.
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
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 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.
This type of error is unlikely to be an error that can be resolved by a retry,
and is triggered in #2296 by files with a timestamp before the unix epoch.
- 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 there was lots of duplicated code in all the
dircache using backends to support DirMove.
This change factors this code into the dircache library.
Dircache was changed to:
- Remove special cases for the root directory
- Remove Fatal errors
- Call FindRoot on behalf of the user wherever possible
- Bring up to modern Go standards
Backends were changed to:
- Remove calls to FindRoot
- Change calls to FindRootAndPath to FindPath
- Don't make special cases for the root
This fixes several corner cases, for example removing a non existent
directory if FindRoot hasn't been called.
- 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.
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 the Features() method would return a different Fs
to that the Features() method was called on if the remote was
instantiated on a file.
The practical effect of this is that optional features, eg `rclone
about` wouldn't work properly when called on a file, and likely this
has been causing low level problems for users of these backends for
ages.
Ideally there would be a test for this, but it turns out that this is
really hard, so instead of that all the backends have been converted
to not copy the Fs and a big warning comment inserted for future
readers.
Fixes#2182
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
Previously this was reading a stale hash from the object leading to
broken integration tests.
This fixes these integration tests TestSyncDoesntUpdateModtime,
TestSyncAfterChangingFilesSizeOnly, TestSyncAfterChangingContentsOnly,
TestSyncWithUpdateOlder, TestSyncUTFNorm.
