d2b37cf61e operations: fix case-insensitive moves in operations.Move #7591
Before this change, operations.moveOrCopyFile had a special section to detect
and handle changing case of a file on a case insensitive remote, but
operations.Move did not. This caused operations.Move to fail for certain
backends that are incapable of renaming a file in-place to an equal-folding name.
(Not all case-insensitive backends have this limitation -- for example, Dropbox
does but macOS local does not.)

After this change, the special two-part-move section from
operations.moveOrCopyFile is factored out to its own function,
moveCaseInsensitive, which is then called from both operations.moveOrCopyFile
and operations.Move.

91b54aafcc rc: add srcFs and dstFs to core/stats and core/transferred stats
Before this change it wasn't possible to see where transfers were
going from and to in core/stats and core/transferred.

When use in rclone mount in particular this made interpreting the
stats very hard.

b4216648e4 bisync: full support for comparing checksum, size, modtime - fixes #5679 fixes #5683 fixes #5684 fixes #5675
Before this change, bisync could only detect changes based on modtime, and
would refuse to run if either path lacked modtime support. This made bisync
unavailable for many of rclone's backends. Additionally, bisync did not account
for the Fs's precision when comparing modtimes, meaning that they could only be
reliably compared within the same side -- not against the opposite side. Size
and checksum (even when available) were ignored completely for deltas.

After this change, bisync now fully supports comparing based on any combination
of size, modtime, and checksum, lifting the prior restriction on backends
without modtime support. The comparison logic considers the backend's
precision, hash types, and other features as appropriate.

The comparison features optionally use a new --compare flag (which takes any
combination of size,modtime,checksum) and even supports some combinations not
otherwise supported in `sync` (like comparing all three at the same time.) By
default (without the --compare flag), bisync inherits the same comparison
options as `sync` (that is: size and modtime by default, unless modified with
flags such as --checksum or --size-only.) If the --compare flag is set, it will
override these defaults.

If --compare includes checksum and both remotes support checksums but have no
hash types in common with each other, checksums will be considered only for
comparisons within the same side (to determine what has changed since the prior
sync), but not for comparisons against the opposite side. If one side supports
checksums and the other does not, checksums will only be considered on the side
that supports them. When comparing with checksum and/or size without modtime,
bisync cannot determine whether a file is newer or older -- only whether it is
changed or unchanged. (If it is changed on both sides, bisync still does the
standard equality-check to avoid declaring a sync conflict unless it absolutely
has to.)

Also included are some new flags to customize the checksum comparison behavior
on backends where hashes are slow or unavailable. --no-slow-hash and
--slow-hash-sync-only allow selectively ignoring checksums on backends such as
local where they are slow. --download-hash allows computing them by downloading
when (and only when) they're otherwise not available. Of course, this option
probably won't be practical with large files, but may be a good option for
syncing small-but-important files with maximum accuracy (for example, a source
code repo on a crypt remote.) An additional advantage over methods like
cryptcheck is that the original file is not required for comparison (for
example, --download-hash can be used to bisync two different crypt remotes with
different passwords.)

Additionally, all of the above are now considered during the final --check-sync
for much-improved accuracy (before this change, it only compared filenames!)

Many other details are explained in the included docs.

7c6f0cc455 operations: fix renaming a file on macOS
Before this change, a file would sometimes be silently deleted instead of
renamed on macOS, due to its unique handling of unicode normalization. Rclone
already had a SameObject check in place for case insensitivity before deleting
the source (for example if "hello.txt" was renamed to "HELLO.txt"), but had no
such check for unicode normalization. After this change, the delete is skipped
on macOS if the src and dst filenames normalize to the same NFC string.

Example of the previous behavior:

88e516adee moveOrCopyFile: avoid panic on --dry-run
Before this change, changing the case of a file on a case insensitive remote
would fatally panic when `--dry-run` was set, due to `moveOrCopyFile`
attempting to access the non-existent `tmpObj` it (would normally have)
created. After this change, the panic is avoided by skipping this step during
a `--dry-run` (with the usual "skipped as --dry-run is set" log message.)

c0968a0987 operations: add logger to log list of sync results -- fixes #7282
Logger instruments the Sync routine with a status report for each file pair,
making it possible to output a list of the synced files, along with their
attributes and sigil categorization (match/differ/missing/etc.)
It is very customizable by passing in a custom LoggerFn, options, and
io.Writers to be written to. Possible uses include:
- allow sync to write path lists to a file, in the same format as rclone check
- allow sync to output a --dest-after file using the same format flags as lsf
- receive results as JSON when calling sync from an internal function
- predict the post-sync state of the destination

For usage examples, see bisync.WriteResults() or sync.SyncLoggerFn()

66929416d4 lsf: add --time-format flag
Before this change, lsf's time format was hard-coded to "2006-01-02 15:04:05",
regardless of the Fs's precision. After this change, a new optional
--time-format flag is added to allow customizing the format (the default is
unchanged).

Examples:
	rclone lsf remote:path --format pt --time-format 'Jan 2, 2006 at 3:04pm (MST)'
	rclone lsf remote:path --format pt --time-format '2006-01-02 15:04:05.000000000'
	rclone lsf remote:path --format pt --time-format '2006-01-02T15:04:05.999999999Z07:00'
	rclone lsf remote:path --format pt --time-format RFC3339
	rclone lsf remote:path --format pt --time-format DateOnly
	rclone lsf remote:path --format pt --time-format max

--time-format max will automatically truncate '2006-01-02 15:04:05.000000000'
to the maximum precision supported by the remote.

fbdf71ab64 operations: fix files moved by rclone move not being counted as transfers
Before this change we were only counting moves as checks. This means
that when using `rclone move` the `Transfers` stat did not count up
like it should do.

This changes introduces a new primitive operations.MoveTransfers which
counts moves as Transfers for use where that is appropriate, such as
rclone move/moveto. Otherwise moves are counted as checks and their
bytes are not accounted.

de185de215 accounting: show server side stats in own lines and not as bytes transferred
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.

07cf5f1d25 operations: fix .rclonelink files not being converted back to symlinks
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

22a14a8c98 operations: fix deadlock when using lsd/ls with --progress - Fixes #7102
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.

1f9c962183 operations: reopen downloads on error when using check --download and cat
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.

279d9ecc56 operations: fix pcloud can't set modified time
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.

5c594fea90 operations: implement uploads to temp name with --inplace to disable
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.

a875320e37 sync,operations: optimise --copy-dest and --compare-dest
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.
