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
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 change rclone used a normal SFTP rename if present to
implement Move.
However the normal SFTP rename won't overwrite existing files.
This fixes it to either use the POSIX rename extension
("posix-rename@openssh.com") or to delete the source first before
renaming using the normal SFTP rename.
This isn't normally a problem as rclone always removes any existing
objects first, however to implement non --inplace operations we do
require overwriting an existing file.
When using ssh-agent to hold multiple keys, it is common practice to configure
openssh to use a specific key by setting the corresponding public key as
the `IdentityFile`. This change makes a similar behavior possible in rclone
by having it parse the `key_file` config as the public key when
`key_use_agent` is `true`.
rclone already attempted this behavior before this change, but it assumed that
`key_file` is the private key and that the public key is specified in
`${key_file}.pub`. So for parity with the openssh behavior, this change makes
rclone first attempt to read the public key from `${key_file}.pub` as before
(for the sake of backward compatibility), then fall back to reading it from
`key_file`.

Fish is different from POSIX-based Unix shells such as bash,
and a bracketed variable references like we use for the
auto-detection echo command is not supported. The command
will return with zero exit code but produce no output on
stdout. There is a message on stderr, but we don't log it
due to the zero exit code:
fish: Variables cannot be bracketed. In fish, please use {$ShellId}.
Fixes#6552
If mkdir fails then before this change it would have thrown an
error.
After this change, if the error indicated that the directory
already exists then the error is not returned to the user.
This fixes a race condition when two rclone threads are trying to
create the same directory.
Windows shells like cmd and powershell needs to use different quoting/escaping
of strings and paths than the unix shell, and also absolute paths must be fixed
by removing leading slash that the POSIX formatted paths have
(e.g. /C:/Users does not work in shell, it must be converted to C:/Users).
Tries to autodetect shell type (cmd, powershell, unix) on first use.
Implemented default builtin powershell functions for hashsum and about when remote
shell is powershell.

strings.ReplaceAll(s, old, new) is a wrapper function for
strings.Replace(s, old, new, -1). But strings.ReplaceAll is more
readable and removes the hardcoded -1.

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.
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
Betweeen rclone v1.54 and v1.55 there was an approx 3x performance
regression when transferring to distant SFTP servers (in particular
rsync.net).
This turned out to be due to the library github.com/pkg/sftp rclone
uses. Concurrent writes used to be enabled in this library by default
(for v1.12.0 as used in rclone v1.54) but they are no longer enabled
(for v1.13.0 as used in rclone v1.55) for safety reasons and it is
necessary to enable them specifically.
The safety concerns are due to the uncertainty as to whether writes
come in order and whether a half completed file might have holes in
it. This isn't a problem for rclone since a) it doesn't restart
uploads and b) it has a post-transfer checksum test.
This change introduces a new flag `--sftp-disable-concurrent-writes`
to control the feature which defaults to false, meaning that
concurrent writes are enabled as in v1.54.
However this isn't quite enough to fix the problem as the sftp library
needs to be able to sniff the size of the stream from the reader
passed in, so this also adds a `Size` interface to the reader to
enable this. This involved a patch to the library.
The library was reverted to v1.12.0 for v1.55.1 - this patch installs
v1.13.0+master to fix the Size interface problem.

In
a3fcadddc8 sftp: close idle connections after --sftp-idle-timeout (1m by default)
Idle SFTP connections were closed after 1 minute. However due to the
way SSH multiplexes connections over a single SSH connection this
meant that if uploads or downloads went on for more than one minute
they failed with "EOF errors" as their underlying connection was
closed.
This fixes the problem by not clearing idle connections if there are
any transfers in progress.
Fixes#5197
This reverts the library update done in this commit.
713f8f357d sftp: fix "file not found" errors for read once servers
Reverting this commit triples the performance to a far away sftp server.
See: https://github.com/pkg/sftp/issues/426
Some sftp servers don't allow the user to access the file after upload.
In this case the error message indicates that using
--sftp-set-modtime=false would fix the problem. However it doesn't
because SetModTime does a stat call which can't be disabled.
Update SetModTime failed: SetModTime stat failed: object not found
After upload this patch checks for an `object not found` error if
set_modtime == false and ignores it, returning the expected size of
the object instead.
It also makes SetModTime do nothing if set_modtime = false
https://forum.rclone.org/t/sftp-update-setmodtime-failed/22873
It introduces a new flag --sftp-disable-concurrent-reads to stop the
problematic behaviour in the SFTP library for read-once servers.
This upgrades the sftp library to v1.13.0 which has the fix.
