Changes in github.com/anacrolix/dms changed upnp.ServiceURN to include a
namespace identifier. This identifier was previously hardcoded, but is
now parsed out of the URN. The old SOAP action header parsing logic was
duplicated in rclone and did not handle this field. Resulting responses
included a URN with an empty namespace identifier, breaking clients.
Before this change, rclone serve sftp operating with a new rclone
after the md5sum/sha1sum detection was reworked to just run a plain
`md5sum`/`sha1sum` command in
3ea82032e7 sftp: support md5/sha1 with rsync.net #3254
Failed to signal to the remote that md5sum/sha1sum wasn't supported as
in
71e172a139 serve/sftp: support empty "md5sum" and "sha1sum" commands
We unconditionally return good hashes even if the remote being served
doesn't support the hash type in question.
This fix checks the hash type is supported and returns an error
MD5 hash not supported
When the backend is first contacted this will cause the sftp backend
to detect that the hash type isn't available.
Unfortunately this may have cached the wrong state so editing or
remaking the config may be necessary to fix it.
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.
This change ensures we call the Shutdown method on backends when
they drop out of the fs/cache and at program exit.
Some backends implement the optional fs.Shutdowner interface. Until now,
Shutdown is only checked and called, when a backend is wrapped (e.g.
crypt, compress, ...).
To have a general way to perform operations at the end of the backend
lifecycle with proper error handling, we can call Shutdown at cache
clear time.
We add a finalize hook to the cache which will be called when values
drop out of the cache.

The https://github.com/nsf/termbox-go library is no longer maintained
so this change replaces it with the maintained
github.com/gdamore/tcell library which has a termbox backwards
compatibility layer.
There are a few minor changes from the termbox library:
- Using Clear with fg bg ColorDefault resulted in a white background for some reason.
- Clear with fg ColorWhite bg ColorBlack was used instead.
- tcell's termbox wrapper doesn't support ColorLightYellow.
- ColorYellow + 8 was used instead.
If the remote on the command line is "remote:subdir", when
deleting "filename", the confirmation message shows the path
"remote:subdirfilename".
Using fspath.JoinRootPath() fixes this. Also use this function
and fs.ConfigString() in other parts of the file, since they
are more appropriate.
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.

Some backends may not provide size for all objects, and instead
return -1. Existing version included these in directory sums,
with strange results. With this commit rclone ncdu will consider
negative sizes as zero, but add a new prefix flag '~' with a
description that indicates the shown size is inaccurate.
Fixes#6084
In this commit
f4c40bf79d mount: add --devname to set the device name sent to FUSE for mount display
The --devname parameter was added. However it was soon noticed that
attempting to mount via the rc gave this error:
mount helper error: fusermount: unknown option 'fsname'
mount FAILED: fusermount: exit status 1
This was because the DeviceName (and VolumeName) parameter was never
being initialised when the mount was called via the rc.
The fix for this was to refactor the rc interface so it called the
same Mount method as the command line mount which initialised the
DeviceName and VolumeName parameters properly.
This also fixes the cmd/mount tests which were breaking in the same
way but since they aren't normally run on the CI we didn't notice.
Fixes#6044
Before this change, the device name was always the remote:path rclone
was configured with. However this can contain sensitive information
and it appears in the `mount` output, so `--devname` allows the user
to configure it.

This link appears to be broken, so here is another reference to (I think) the same file that provides a good example of coba. We could also do the current commit 8312004f41/cli/cobra.go although it might be better to maintain an up to date example.
Previously only the fs being checked on gets passed to
GetModifyWindow(). However, in most tests, the test files are
generated in the local fs and transferred to the remote fs. So the
local fs time precision has to be taken into account.
This meant that on Windows the time tests failed because the
local fs has a time precision of 100ns. Checking remote items uploaded
from local fs on Windows also requires a modify window of 100ns.
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.
Before this fix, rclone only generated an RSA server key when the user
didn't supply a key.
However the RSA server key is being deprecated as it is now insecure.
This patch generates an ECDSA server key too which will be used in
preference over the RSA key, but the RSA key will carry on working.
Fixes#5671
This patch will:
- add --daemon-wait flag to control the time to wait for background mount
- remove dependency on sevlyar/go-daemon and implement backgrounding directly
- avoid setsid during backgrounding as it can result in race under Automount
- provide a fallback PATH to correctly run `fusermount` under systemd as it
runs mount units without standard environment variables
- correctly handle ^C pressed while background process is being setting up
Current way of checking whether mountpoint has been already mounted (directory
list) can result in race if rclone runs under Automount (classic or systemd).
This patch adopts Linux ProcFS for the check. Note that mountpoint is considered
empty if it's tagged as "mounted" by autofs. Also ProcFS is used to check whether
rclone mount was successful (ie. tagged by a string containing "rclone").
On macOS/BSD where ProcFS is unavailable the old method is still used.
This patch also moves a few utility functions unchanged to utils.go:
CheckOverlap, CheckAllowings, SetVolumeName.
This replaces built-in os.MkdirAll with a patched version that stops the recursion
when reaching the volume part of the path. The original version would continue recursion,
and for extended length paths end up with \\? as the top-level directory, and the error
message would then be something like:
mkdir \\?: The filename, directory name, or volume label syntax is incorrect.
Switched from talking about "unchanged" files to "identical" files.
I found out the hard way that the rclone copy will overwrite newer files.
Looking at posts in the rclone forum, this is a common experience.
The docs for copy have referred to "unchanged" files.
This is ambiguous because it intuitively introduces a sense
of chronology, but chronology is irrelevant.
Rclone only "cares" about difference, not change.
Signal handling by the `atexit` package needs acceess to
`exitCodeUncategorizedError`. With this change all exit status values
are moved to a dedicated package so that they can be reused.

Currently rclone check supports matching two file trees by sizes and hashes.
This change adds support for SUM files produced by GNU utilities like sha1sum.
Fixes#1005
Note: checksum by default checks, hashsum by default prints sums.
New flag is named "--checkfile" but carries hash name.
Summary of introduced command forms:
```
rclone check sums.sha1 remote:path --checkfile sha1
rclone checksum sha1 sums.sha1 remote:path
rclone hashsum sha1 remote:path --checkfile sums.sha1
rclone sha1sum remote:path --checkfile sums.sha1
rclone md5sum remote:path --checkfile sums.md5
```
Some environment variables didn’t behave like their corresponding
command line flags. The affected flags were --stats, --log-level,
--separator, --multi-tread-streams, --rc-addr, --rc-user and --rc-pass.
Example:
RCLONE_STATS='10s'
rclone check remote: remote: --progress
# Expected: rclone check remote: remote: --progress –-stats=10s
# Actual: rclone check remote: remote: --progress
Remote specific options set by environment variables was overruled by
less specific backend options set by environment variables. Example:
RCLONE_DRIVE_USE_TRASH='false'
RCLONE_CONFIG_MYDRIVE_USE_TRASH='true'
rclone deletefile myDrive:my-test-file
# Expected: my-test-file is recoverable in the trash folder
# Actual: my-test-file is permanently deleted (not recoverable)
Backend specific options set by environment variables was overruled by
general backend options set by environment variables. Example:
RCLONE_SKIP_LINKS='true'
RCLONE_LOCAL_SKIP_LINKS='false'
rclone lsd local:
# Expected result: Warnings when symlinks are skipped
# Actual result: No warnings when symlinks are skipped
# That is RCLONE_SKIP_LINKS takes precedence
The above issues have been fixed.
The debug logging (-vv) has been enhanced to show when flags are set by
environment variables.
The documentation has been enhanced with details on the precedence of
configuration options.
See pull request #5341 for more information.
- Unify all hash names as lowercase alphanumerics without punctuation.
- Legacy names continue to work but disappear from docs, they can be depreciated or dropped later.

This also factors the config questions into a state based mechanism so
a backend can be configured using the same dialog as rclone config but
remotely.
This is a very large change which turns the post Config function in
backends into a state based call and response system so that
alternative user interfaces can be added.
The existing config logic has been converted, but it is quite
complicated and folloup commits will likely be needed to fix it!
Follow up commits will add a command line and API based way of using
this configuration system.
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.
Restructuring of config code in v1.55 resulted in config
file being loaded early at process startup. If configuration
file is encrypted this means user will need to supply the password,
even when running commands that does not use config.
This also lead to an issue where mount with --deamon failed to
decrypt the config file when it had to prompt user for passord.
Fixes#5236Fixes#5228
A new command `rclone config touch` which calls config.SaveConfig().
Useful during testing of configuration location things.
It will ensure the config file exists and test that it is writable.
Before this patch selfupdate detected ANY build with cmount tag as a build
having libFUSE capabilities. However, only dynamic builds really have it.
The official linux builds are static and have the cmount tag as of the time
of this writing. This results in inability to update official linux binaries.
This patch fixes that. The build can be fixed independently.
This patch modifies the output of `rclone version`.
The `os/arch` line is split into `os/type` and `os/arch`.
The `go version` line is now tagged as `go/version` for consistency.
Additionally the `go/linking` line tells whether the rclone
was linked as a static or dynamic executable.
The new `go/tags` line shows a space separated list of build tags.
The info about linking and build tags is also added to the output
of the `core/version` RC endpoint.
It was discovered `rclone mount` (but not `rclone cmount`) cached
directories after rename which it shouldn't have done.
This caused IO errors when trying to access files in renamed
directories on bucket based file systems.
This turned out to be the kernel caching the directories as basil/fuse
sets their expiry time to 60s for some reason.
This fix invalidates the relevant kernel cache entries in the for the
directories which fixes the problem.

If you are using rclone a library you can decide to use the rclone
config file system or not by calling
configfile.LoadConfig(ctx)
If you don't you will need to set `config.Data` to an implementation
of `config.Storage`.
Other changes
- change interface of config.FileGet to remove unused default
- remove MustValue from config.Storage interface
- change GetValue to return string or bool like elsewhere in rclone
- implement a default config file system which panics with helpful error
- implement getWithDefault to replace the removed MustValue
- don't embed goconfig.ConfigFile so we can change the methods
Previously rclone set --daemon-timeout to 15m by default. However
osxfuse seems to be ignoring that value since it is above the maximum
value of 10m. This is conjecture since the source of osxfuse is no
longer available.
Setting the value to 10m seems to resolve the problem.

Before this change, if one connection was authenticating this would
block any others from authenticating.
This was due to ssh.NewServerConn not being called in a go routine

Implemented empty folder flag for ncdu browser interface. If there is
empty folder in the list the flag e is prepended before size. If there
is no empty folder this flag is ommited. It has the same behaviour as
original ncdu browser. (https://dev.yorhel.nl/ncdu/man)
When a directory cannot be walk-ed because of a permissions error
- or any error for that matter -, ncdu mode keeps track of the error
and highlights directories that could not be read.
Previously, the error would cause ncdu to abort.
Now, directories with unreadable sub-directories are displayed in yellow and
a message warns that the total may be underestimated.
Unreadable directories themselves are displayed in red along with the error message
Add --network-mode option to activate mounting as network drive without having to set volume prefix.

Allow full network share unc path as mountpoint, which will also implicitely activate network drive mounting, and the specified path will be used as volume prefix and the remote will be mounted on an automatically assigned drive letter instead.
This commit modifies the operations.hashSum function by adding an alternate code path. This code path is triggered by passing downloadFlag = True. When activated, rclone will download files from the remote and hash them locally. downloadFlag = False preserves the existing behavior of using the remote to retrieve the hash.
This commit modifies HashLister to support the new hashSum method as well as consolidating the roles of HashLister, HashListerBase64, Md5sum, and Sha1sum. The printing of hashes from the function defined in HashLister has been revised to work with --progress. There are light changes to operations.syncFprintf and cmd.startProgress for this.
The unit test operations_test.TestHashSums is modified to support this change and test the download functionality.
The command functions hashsum, md5sum, sha1sum, and dbhashsum are modified to support this change. A download flag has been added and an output-file flag has been added. The output-file flag writes hashes to a file instead of stdout to avoid the need to redirect stdout.
When using `--baseurl` before this patch, if a request was made to the
base URL without a trailing / then rclone would return a 404 error.
Unfortunately GVFS / Nautilus makes the request without the /
regardless of what the user put in.
This patch redirects the request to the base URL with a /. So if the
user was using `--baseurl rclone` then a request to
http://localhost/rclone would be redirected with a 308 response to

Introduce a tentative draft see-link format the end of sections to try
rather than lots of in-para links.
Update about.go incl link to list of backends not supporting about.
In list of backends not supporting about, include link to about command
reference.
I appreciate there may be decisions to make going forward about whether
command links should be code formatted, and using proper pretty url
links, but I have fudged that for now.
Update backend pages that do not support about with wording used
previously for ftp - it is in passive voice but I can live with it. (my
own wording and fault). The note is applied to a limitations section. If
one does not already exist it is created (even if there are other
limitations with their own sections)
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 shouldn't be read as encouraging the use of math/rand instead of
crypto/rand in security sensitive contexts, rather as a safer default
if that does happen by accident.
This caches all the objects returned from the List call. This makes
opening them much quicker so speeds up prune and restores. It also
uses fewer transactions. It can be disabled with
`--cache-objects=false`.
This was discovered when using the B2 backend when the budget was
being blown on list object calls which can avoided with a bit of
caching.
For typical 1 million file backup for a latop or server this will only
use a small amount more memory.
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.
It turns out that NFS calls mknod in FUSE even though we have create
defined. This was causing EIO errors when creating files.
This patch fixes it by implementing mknod. The way it is implemented
means that to write to an NFS file system you'll need --vfs-cache-mode
writes.
Before this change
RCLONE_DRIVE_CHUNK_SIZE=111M rclone help flags | grep drive-chunk-size
Would show the default value, not the setting of RCLONE_DRIVE_CHUNK_SIZE
as the non backend flags do.
This change makes it work as expected by setting the default of the
option to the environment variable.

`rclone obscure` currently only accepts a command line argument of `password` to generate
an obfuscated password. This is an issue since generating obfuscated passwords programatically
requires sending the plain text password as a shell argument, which can cause problems if the
password contains shell characters, or if the password is from an untrusted source.
This patch opens up STDIN which will allow developers to open the STDIN source and print a password
directly to `rclone obscure`, which can increase safety and convenince.
This is preparation for getting the Accounting to check the context,
buf first we need to get it in place. Since this is one of those

Before this change when reading directories we would use the directory
handle and the Readdir(-1) call on the directory handle. This worked
fine for the first read, but if the directory was read again on the
same handle Readdir(-1) returns nothing (as per its design).
It turns out that macOS leaves the directory handle open and just
re-reads the data from it, so this problem causes directories to start
out full then subsequently appear empty.
macOS/OSXFUSE is passing an offset of 0 to the Readdir call telling
rclone to seek in the directory, but we've told FUSE that we can't
seek by always returning ofst=0 in the fill function.
This fix works around the problem by reading the directory from the
path each time, ignoring the actual handle. This should be no less
efficient.
We will return an ESPIPE if offset is ever non 0.
There are possible corner cases reading deleted directories which this
ignores.

It is a source of confusion for users that `rclone mkdir` on a remote

When wrapping a backend that supports Server Side Copy (e.g. `b2`, `s3`)
and configuring the `tmp_upload_path` option, the `cache` backend would
erroneously report that Server Side Copy/Move was not supported, causing
operations such as file moves to fail. This change fixes this issue
under these circumstances such that Server Side Copy will now be used
when the wrapped backend supports it.

Before this change there was some ambiguity about whether passwords

This includes a new directory listing template which was originally
from the Caddy project (used with permission and copyright attribution).
This is used whenever we serve directory listings so `rclone serve
http`, `rclone serve webdav` and `rclone rcd --rc-serve`
This also modifies the tests so they work with the original template which
is easier to debug.
Before this change Windows would read a directory then immedately stat
every item in the directory.
After this change we return the stat information along with the
directory which stops so many callbacks.
Before this change, the current working directory could disappear
according to the Linux kernel.
This was caused by mount returning different nodes with the same
information in.
This change uses vfs.Node.SetSys to cache the information so we always
return the same node.
Before this change if you specified --hash MD5 in rclone lsf it would
calculate all the hashes and just return the MD5 hash which was very
slow on the local backend.
Likewise specifying --hash on rclone lsjson was equally slow.
This change introduces the --hash-type flag (and corresponding
internal parameter) so that the hashes required can be selected in
lsjson.
This is used internally in lsf when the --hash parameter is selected
to speed up the hashing by only hashing with the one hash specified.
Fixes#4181
These commands are for implementing backend specific
functionality. They have documentation which is placed automatically
into the backend doc.
There is a simple test for the feature in the backend tests.
The tests are now run for the mount commands and for the plain VFS.
This makes the tests much easier to debug when running with a VFS than
through a mount.
This allows rclone to exit with a non-zero return code if no files are
transferred. This is useful when calling rclone as part of a workflow/script
pipeline as it allows the end user to stop processing if no files have been
transferred.
NB: Enabling this option will return in rclone exiting non-zero if there are no
transfers. Depending on how your're currently using rclone in your scripts,
this may break existing setups!
--files-from parses input files by ignoring comments starting with # and ;

Basically, solving #3541 with a different approach - bringing in
the upstream upnpav module, and changing ChildCount from int to a
*int to avoid childCount="0" in the XML output when that value is
simply unknown.
Current approach is leading to some recursion issues and according
to the DLNA spec it shouldn't be necessary, anyway.
Before this changed we unconditionally fetched the MimeType. On Some
backends like s3 and swift this takes an extra transaction which meant
that `lsf` on those backends was needlessly slow.
This adds an internal option so `lsf` can declare whether it wants
MimeTypes or not depending on whether the user asked for them and an
external flag `--no-mimetype` for `lsjson`.

Unfortunately bcrypt only hashes the first 72 bytes of a given input
which meant that using it on ssh keys which are longer than 72 bytes
was incorrect.
This swaps over to using sha256 which should be adequate for the
purpose of protecting in memory passwords where the unencrypted
password is likely in memory too.
The failure is this which is not reproducable locally, only on the CI
servers.

Instead of using ioutil.WriteFile this fix uses an equivalent based on
rclone's lib/file which doesn't set the exclusive flag on
Windows. This allows files to be deleted that are open. It also
deletes existing files if an error is received and retries.
For few commands, RClone counts a error multiple times. This was fixed by
creating a new error type which keeps a flag to remember if the error has
already been counted or not. The CountError function now wraps the original
error eith the above new error type and returns it.
Before this change the race tests were taking too long. The bcrypt
function went from about 20ms to 1s under the race detector and this
is called for every transaction on webdav.
This change reduces the bcrypt strength so it takes 1ms non race so
the race tests pass and still has adequate security for in memory only
storage.

Before this change `rclone mount` would give this error on FreeBSD

This change sets the default for --daemon-timeout to 0 on FreeBSD
which fixes the problem.

Before this change the sftp handler returned a nil error for unknown

If a file handle is duplicated with dup() and the duplicate handle is
flushed, rclone will go ahead and close the file, making the original
file handle stale. This change removes the close() call from Flush() and
replaces it with FlushWrites() so that the file only gets closed when
Release() is called. The new FlushWrites method takes care of actually
writing the file back to the underlying storage.
