When using `--no-traverse` the march routines call NewObject on each
potential object in the destination.
The concurrency limiter was accidentally arranged so that there were
`--checkers` * `--checkers` NewObject calls going on at once.
This became obvious when using the sftp backend which used too many
connections.
Fixes#5824
After the copy refactor:
179f978f75 operations: refactor Copy into methods on an temporary object
There was some confusion in the code about server side copies - should
they or shouldn't they use partials?
This manifested in unit test failures for remotes which supported
server side Copy and PartialUploads. This combination is rare and only
exists in the sftp backend with the --sftp-copy-is-hardlink flag.
This fix makes the choice that backends which set PartialUploads
always use partials even for server side copies.
operations.Copy had become very unwieldy. This refactors it into
methods on a copy object which is created for the duration of the
copy. This makes it much easier to read and reason about.
This almost 100% backwards compatible. The only difference being that
in the rc options/get output DumpMode will be output as strings
instead of integers. This is a lot more convenient for the user. They
still accept integer inputs though so the fallout from this should be
minimal.
This almost 100% backwards compatible. The only difference being that
in the rc options/get output CutoffMode, LogLevel, TerminalColorMode
will be output as strings instead of integers. This is a lot more
convenient for the user. They still accept integer inputs though so
the fallout from this should be minimal.
Before this change backend types were printing incorrectly as the name
of the type, not what was defined by the Type() method.
This was not working due to not calling the Type() method. However
this needed to be defined on a non-pointer type due to the way the
options are handled.
Before this change, the maximum number of connections was set to 10.
This means that b2 could deadlock while uploading multipart uploads
due to a lock being held longer than it should have been.
Before this change the concurrency used for an upload was rather
inconsistent.
- if size below `--backend-upload-cutoff` (default 200M) do single part upload.
- if size below `--multi-thread-cutoff` (default 256M) or using streaming
uploads (eg `rclone rcat) do multipart upload using
`--backend-upload-concurrency` to set the concurrency used by the uploader.
- otherwise do multipart upload using `--multi-thread-streams` to set the
concurrency.
This change makes the default for the concurrency used be the
`--backend-upload-concurrency`. If `--multi-thread-streams` is set and larger
than the `--backend-upload-concurrency` then that will be used instead.
This means that if the user sets `--backend-upload-concurrency` then it will be
obeyed for all multipart/multi-thread transfers and the user can override them
all with `--multi-thread-streams`.
See: #7056
- fix docs and error messages for multithread
- use sync/errgroup built in concurrency limiting
- re-arrange multithread code
- don't continue multi-thread uploads if one part fails
Before this change, when using --cutoff-mode=soft and --max-duration
rclone deadlocked when the cutoff limit was reached.
This was because the sync objects Pipe became full and nothing was
emptying it because the cutoff was reached.
This changes the context for putting items into the pipe to be the one
that gets cancelled when the cutoff is reached.

Currently, the average transfer speed will stop calculating 1 minute
after the last queued transfer completes. This causes the average to
stop calculating when checking is slow and the transfer queue becomes
empty.
This change will require all checks to complete before stopping the
average speed calculation.
In this commit:
432d5d1e20 operations: fix overlapping check on case insensitive file systems
We introduced a test that makes no sense. This happens to pass without --fast-list and fail with it.
This removes the test.
Before this change we showed both server side moves and server side
copies as bytes transferred.
This made a nice easy to use stats display, but also caused confusion
for users who saw unrealistic transfer times. It also caused a problem
with --max-transfer and chunker which renames each chunk after
uploading which was counted as a transfer byte.
This patch instead accounts the server side move and copy statistics
as a seperate lines in the stats display which will only appear if
there are any server side moves / copies. This is also output in the
rc.
This gives users something to look at when transfers are running which
was the point of the original change but it now means that transfer
bytes represents data transfers through this rclone instance only.
Fixes#7183
This adds an additional parameter to the creation of each flag. This
specifies one or more flag groups. This **must** be set for global
flags and **must not** be set for local flags.
This causes flags.md to be built with sections to aid comprehension
and it causes the documentation pages for each command (and the
`--help`) to be built showing the flags groups as specified in the
`groups` annotation on the command.

Some changes about test cases:
Because MiddlewareCORS will return early on OPTIONS request,
this middleware should only be used once at NewServer function.
Test cases should pass AllowOrigin config instead of adding
this middleware again.
A new test case was added to test CORS preflight request with
an authenticator. Preflight request should always return 200 OK
regardless of autentications.

Before this change, the overlapping check could erroneously give this
error on case insensitive file systems:
Failed to sync: destination and parameter to --backup-dir mustn't overlap
The code was fixed and re-worked to be simpler and more reliable.
See: https://forum.rclone.org/t/backup-dir-cannot-be-in-root-even-when-excluded/39844/
Before this change the new partial downloads code was causing symlinks
to be copied as regular files.
This was because the partial isn't named .rclonelink so the local
backend saves it as a normal file and renaming it to .rclonelink
doesn't cause it to become a symlink.
This fixes the problem by not copying .rclonelink files using the
partials mechanism but reverting to the previous --inplace behaviour.
This could potentially be fixed better in the future by changing the
local backend Move to change files to and from symlinks depending on
their name. However this was deemed too complicated for a point
release.
This also adds a test in the local backend. This test should ideally
be in operations but it isn't easy to put it there as operations knows
nothing of symlinks.
Fixes#7101

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
The --progress flag overrides operations.SyncPrintf in order to do its
magic on stdout without interfering with other output.
Before this change the syncFprintf routine in operations (which is
used to print all output to stdout) was taking the
operations.StdoutMutex and the printProgress function in the
--progress routine was also attempting to take the same mutex causing
a deadlock.
This patch fixes the problem by moving the locking from the
syncFprintf function to SyncPrintf. It is then up to the function
overriding this to lock the StdoutMutex. This ensures the StdoutMutex
can never cause a deadlock.
Before this change if using --fast-list on a directory with more than
a few thousand directories in it DirTree.CheckParents became very slow
taking up to 24 hours for a directory with 1,000,000 directories in
it.
This is because it becomes an O(N²) operation as DirTree.Find has to
search each directory in a linear fashion as it is stored as a slice.
This patch fixes the problem by scanning the DirTree for directories
before starting the CheckParents process so it never has to call
DirTree.Find.
After the fix calling DirTree.CheckParents on a directory with
1,000,000 directories in it will take about 1 second.
Anything which calls DirTree.Find can potentially have bad performance
so in the future we should redesign the DirTree to use a different
underlying datastructure or have an index.

when multi-thread downloading is enabled, rclone used
to send a write to disk after every read, resulting in a lot
of small writes to different locations of the file.
depending on the underlying filesystem or device, it can be more
efficient to send bigger writes.
This commit
3567a47258 fs: make ConfigString properly reverse suffixed file systems
made fs.ConfigString() return the full config of the backend. Because
mount was using this to make a volume name it started to make volume
names with illegal characters in which couldn't be mounted by macOS.
This fixes the problem by making a separate fs.ConfigStringFull() and
using that where appropriate and leaving the original
fs.ConfigString() function untouched.

The SIGUSR2 signal handler for bandwidth limits currently only starts
if rclone is started at a time when a bandwidth limit applies. This
means that if rclone starts _outside_ such a time, i.e. with no
bandwidth limits, then enters a time where bandwidth limits do apply,
it will not be possible to use SIGUSR2 to toggle it.
This fixes that by always starting the signal handler, but only
toggling the limiter if there is a bandwidth limit configured.
In 04aa6969a4 we updated the displayed speed to be a rolling
average in core/stats and the progress output but we didn't update the
Prometheus metrics.
This patch updates the Prometheus metrics too.
Fixes#7053
Before this change if doing a recursive directory listing with
`--files-from` if more than `--checkers` files errored (other than
file not found) then rclone would deadlock.
This fixes the problem by exiting on the first error.
Before this change partially uploaded files (when --inplace is not in
effect) would be left lying around in the file system if rclone was
killed in the middle of a transfer.
This adds an exit handler to remove the file and removes it when the
file is complete.
Before this change, some parts of operations called the Open method on
objects directly, and some called NewReOpen to make an object which
can re-open itself on errors.
This adds a new function operations.Open which should be called
instead of fs.Object.Open to open a reliable stream of data and
changes all call sites to use that.
This means `rclone check --download` and `rclone cat` will re-open
files on failures.
See: https://forum.rclone.org/t/does-rclone-support-retries-for-check-when-using-download-flag/38641
Before this change we tested special errors for straight equality.
This works for all normal backends, but the union backend may return
wrapped errors which contain the special error types.
In particular if a pcloud backend was part of a union when attempting
to set modification times the fs.ErrorCantSetModTime return wasn't
understood because it was wrapped in a union.Error.
This fixes the problem by using errors.Is instead in all the
comparisons in operations.
See: https://forum.rclone.org/t/failed-to-set-modification-time-1-error-pcloud-cant-set-modified-time/38596
Set this automatically for any backend which implements UnWrap and
manually for combine and union which can't implement UnWrap but do
overlay other backends.
When copying to a backend which has the PartialUploads feature flag
set and can Move files the file is copied into a temporary name first.
Once the copy is complete, the file is renamed to the real
destination.
This prevents other processes from seeing partially downloaded copies
of files being downloaded and prevents overwriting the old file until
the new one is complete.
This also adds --inplace flag that can be used to disable the partial
file copy/rename feature.

Implement a Partialuploads feature flag to mark backends for which
uploads are not atomic.
This is set for the following backends

Before this patch, files or directories with unknown modtime would
appear as the current date.
When mounted some systems look at modification dates of directories to
see if they change and having them change whenever they drop out of
the directory cache is not optimal.
See #6986
Before this change we renamed file systems with overridden config with
{suffix}.
However this meant that ConfigString produced a value which wouldn't
re-create the file system.
This uses an internal hash to keep note of what config goes which
which {suffix} in order to remake the config properly.
When using `rclone cat` to print the contents of several files, the
user may want to inject some separator between the files, such as a
comma or a newline. This patch adds a `--separator` option to the `cat`
command to make that possible. The default value remains an empty
string, `""`, maintaining the prior behavior of `rclone cat`.
Closes#6968
Before this change we weren't outputing a debug log on the start of a
transfer for files which existed on the source but not in the
destination.
This was different to the single file copy routine.
If a file has two (or more) extensions and the second (or subsequent)
extension is recognised as a valid mime type, then the suffix will go
before that extension. So `file.tar.gz` would be backed up to
`file-2019-01-01.tar.gz` whereas `file.badextension.gz` would be
backed up to `file.badextension-2019-01-01.gz`
