- 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.

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
- local
- ftp
- sftp
See #3770
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`
Fixes#6892
In this commit we accidentally removed the global --rc flags.
0df7466d2b cmd/rcd: Fix command docs to include command specific prefix (#6675)
This re-instates them.
Before this change using operations/stat with a remote pointing to a
dir with a trailing / would return a null output rather than the
correct info.
This was because the directory was not found with a trailing slash in
the directory listing.
Fixes#6817
Before this change if both --progress and --interactive were set then
the screen display could become muddled.
This change makes --progress and --interactive use the same lock so
while rclone is asking for interactive questions, the progress will be
paused.
Fixes#6755
This change addresses two issues with commands that re-used
flags from common packages:
1) cobra.Command definitions did not include the command specific
prefix in doc strings.
2) Command specific flag prefixes were added after generating
command doc strings.
The recent changes to remove race conditions from --max-delete have
made these tests fail on chunker with s3 because they do copy then
delete and the deletes are being counted in the --max-delete(-size)
counts.
If using rclone move and --check-first and --order-by then rclone uses
the transfer routine to delete files to ensure perfect ordering.
This will cause the transfer stats to have a larger than expected
number of items in it so we don't enable this by default.
Fixes#6033
There were some places (e.g. deleting files) where we were using
--transfers instead of --checkers to control the concurrency when
files weren't being transferred.
These have been updated to use --checkers.
Before this change, all types of checkers showed "checking" after the
file name despite the fact that not all of them were checking.
After this change, they can show
- checking
- deleting
- hashing
- importing
- listing
- merging
- moving
- renaming

No need to report hours, minutes, and even seconds when the
ETA is several years, e.g. "292y24w3d23h47m16s". Now only
reports the 3 most significant units, sacrificing precision,
e.g. "292y24w3d", "24w3d23h", "3d23h47m", "23h47m16s".
Fixes#6381
Integer overflow would lead to ETA such as "-255y7w4h11m22s966ms",
as reported in #6381. Now the value will be clipped at the maximum
"292y24w3d23h47m16s", and it will be shown as infinity.
Previously it was limited to plain ASCII (0-9, A-Z, a-z).
Implemented by adding \p{L}\p{N} alongside the \w in the regex,
even though these overlap it means we can be sure it is 100%
backwards compatible.
Fixes#6618
The BSD-style license that Go uses requires the license to be included
with the source distribution; so add it as LICENSE.wasmexec (to avoid
confusion with the other licenses in rclone) and note the location of
the license in wasm_exec.js itself.
* fs: add TerminalColorMode type
* fs: add new config(flags) for TerminalColorMode
* lib/terminal: use TerminalColorMode to determine how to handle colors
* Add documentation for '--terminal-color-mode'
* tree: remove obsolete --color replaced by global --color
This changes the default behaviour of tree. It now displays colors by
default instead of only displaying them when the flag -C/--color was
active. Old behaviour (no color) can be achieved by setting --color to
'never'.
Fixes: #6604
Before this change if we copied files of unknown size, then they lost
their metadata.
This was particularly noticeable using --s3-decompress.
This change adds metadata to Rcat and RcatSized and changes Copy to
pass the metadata in when it calls Rcat for an unknown sized input.
Fixes#6546
Solves link error while running rclone's wasm version. Go's `walltime1` function was renamed to `walltime`. This commit updates wasm_exec.js with the new name.
A very common mistake for new users of rclone is to use a remote name
without a colon. This can be on the command line or in the config when
setting up a crypt backend.
This change checks to see if the user uses a path which matches a
remote name and gives an NOTICE like this if they do
NOTICE: "remote" refers to a local folder, use "remote:" to refer to your remote or "./remote" to hide this warning

8d1fff9a82 local: obey file filters in listing to fix errors on excluded files
We started using filters in the local backend so the user could short
circuit troublesome files/directories at a low level.
However this caused a number of integration tests to fail. This turned
out to be in backends wrapping the local backend. For example the
combine backend test failed because it changes the paths passed to the
local backend so they no longer match the paths in the current filter.
To fix this, a new feature flag `FilterAware` was added and the
UseFilter context flag is only passed to backends which support it. As
the wrapping backends don't support the flag, this fixes the problems
in the integration tests.
In future the wrapping backends could modify the active filters to
match the path modifications and then they could set the FilterAware
flag.
See #6376
Before this change we assumed that github.com/Unknwon/goconfig was
threadsafe as documented.
However it turns out it is not threadsafe and looking at the code it
appears that making it threadsafe might be quite hard.
So this change increases the lock coverage in configfile to cover the
goconfig uses also.
Fixes#6378
Before this fix, the chunksize calculator was using the previous size
of the object, not the new size of the object to calculate the chunk
sizes.
This meant that uploading a replacement object which needed a new
chunk size would fail, using too many parts.
This fix fixes the calculator to take the size explicitly.
Before this fix, the parsing code gave an error like this
parsing "2022-08-02 07:00:00" as fs.Time failed: expected newline
This was due to the Scan call failing to read all the data.
This patch fixes that, and redoes the tests
Before this change --compare-dest and --copy-dest would check to see
if the compare/copy object existed first, before seeing if the
destination object was present.
This is inefficient, because in most --copy-dest syncs the destination
will be present and the compare/copy object need never be tested.
--compare-dest syncs may also be speeded up if they are done to the
same directory repeatedly.
This fixes the problem by re-arranging the logic so if the transfer is
not needed then the compare/copy object is never tested.
See: https://forum.rclone.org/t/union-with-copy-dest-enabled-is-slower-than-expected/32172
strings.Title has been deprecated since Go 1.18 and an alternative has been
available since Go 1.0. The rule Title uses for word boundaries does not handle
Unicode punctuation properly. Use golang.org/x/text/cases instead.
Most of the time this will make no difference to user logs, however
the difference may be visible in JSON logs and on the rare occasions
src and dst are pointing to different file names.
