This message is a double panic and was actually caused by an assertion
panic in:
vfs/vfscache/downloaders/downloaders.go
This is triggered by the code added relatively recently to fix a bug
with renaming files:
ec72432cec vfs: fix failed to _ensure cache internal error: downloaders is nil error
So it appears that item.o may be nil at this point.
This patch detects item.o being nil and fetches it again with NewObject.

Before this change we ran the tests and the mount in the same process.
This could cause deadlocks and often did, and made the mount tests
very unreliable.
This fixes the problem by running the mount in a seperate process and
commanding it via a pipe over stdin/stdout.
When using filepath.Dir, a difference to path.Dir is that it returns os PathSeparator
instead of slash when the path consists entirely of separators.
Also fixed casing of the function name, use OS in all caps instead of Os
as recommended here: https://github.com/golang/go/wiki/CodeReviewComments#initialisms
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
This error was caused by renaming an open file.
When the file was renamed in the cache, the downloaders were cleared,
however the downloaders were not re-opened when needed again, instead
this error was generated.
This fix re-opens the downloaders if they have been closed by renaming
the file.
Fixes#5984
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.
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.
Before this change file handles could get closed while the truncate
the file handles loop was running.
This would mean that ocassionally an ECLOSED (which is translated into
EBADF by cmd/mount) would spuriously be returned if Release happened
to happen in the middle of a Truncate call (Setattr called with
size=0).
This change ignores the ECLOSED while truncating file handles.

Before this change, if there was an existing file being uploaded when
a file was renamed on top of it, then both would be uploaded. This
causes a duplicate in Google Drive as both files get uploaded at the
same time. This was triggered reliably by LibreOffice saving doc
files.
This fix removes any duplicates in the upload queue on rename.
Before this change but after:
aea8776a43 vfs: fix modtimes not updating when writing via cache #4763
When a file was opened read-only the modtime was read from the cached
file. However this modtime wasn't correct leading to an incorrect
result.
This change fixes the definition of `item.IsDirty` to be true only
when the data is dirty. This fixes the problem as a read only file
isn't considered dirty.
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.
The vfs-cache-max-size parameter is probably confusing to many users.
The cache cleaner checks cache size periodically at the --vfs-cache-poll-interval
(default 60 seconds) interval and remove cache items in the following order.
(1) cache items that are not in use and with age > vfs-cache-max-age
(2) if the cache space used at this time still is larger than
vfs-cache-max-size, the cleaner continues to remove cache items that are
not in use.
The cache cleaning process does not remove cache items that are currently in use.
If the total space consumed by in-use cache items exceeds vfs-cache-max-size, the
periodical cache cleaner thread does not do anything further and leaves the in-use
cache items alone with a total space larger than vfs-cache-max-size.
A cache reset feature was introduced in 1.53 which resets in-use (but not dirty,
i.e., not being updated) cache items when additional cache data incurs an ENOSPC
error. But this code was not activated in the periodical cache cleaning thread.
This patch adds the cache reset step in the cache cleaner thread during cache
poll to reset cache items until the total size of the remaining cache items is
below vfs-cache-max-size.
Before this fix, doing CTRL-C and CTRL-V on a file in Windows explorer
caused the **source** and the the destination to be truncated to 0.
This is because Windows opens the source file with Create with flags
`O_RDWR|O_CREATE|O_EXCL` but doesn't write to it - it only reads from
it. Rclone was taking the call to Create as a signal to always make a
new file, but this is incorrect.
This fix reads an existing file from the directory if it exists when
Create is called rather than always creating a new one. This fixes the
problem.
Fixes#5181
Before this change, if a directory was renamed and it or any children
had virtual entries in it they weren't flushed.
The consequence of this was that the directory path got out sync with
the actual position of the directory in the tree, leading to listings
of the old directory rather than the new one.
The fix renames any directories remaining after the ForgetAll to have
the correct path which fixes the problem.

When using --vfs-cache-mode writes or full if a file was opened for
write intent, the modtime was set and the file was closed without
being modified the modtime would never be written back to storage.
The sequence of events
- app opens file with write intent
- app does set modtime
- rclone sets the modtime on the cache file, but not the remote file
because it is open for write and can't be set yet
- app closes the file without changing it
- rclone doesn't upload the file because the file wasn't changed so
the modtime doesn't get updated
This fixes the problem by making sure any unapplied modtime changes
are applied even if the file is not modified when being closed.
Fixes#4795
Before this change, rclone would return the modification times of the
cache file or the pending modtime which would be more accurate than
the modtime that the backend was capable of.
This meant that the modtime would be change slightly when the item was
actually uploaded.
For example modification times on Google Drive would be rounded to the
nearest millisecond.
This fixes the VFS layer to always return modtimes directly from an
object stored on the remote, or rounded to the precision that the
remote is capable of.
Before this change, rclone would set the modification time of an
object after it had been uploaded. However with --vfs-cache-mode
writes and above, the modification time of the object is already
correct as the cache backing file gets set with the correct
modification time before upload.
Setting the modification time causes another version to be created on
backends such as S3 so it should be avoided if possible.
This change checks to see if the modification time needs changing and
only sets it if necessary.
See: https://forum.rclone.org/t/produce-2-versions-when-overwrite-an-object-in-min-io/19634
Some backends, most notably S3, do not report the amount of bytes used.
This patch introduces a new flag that allows instead of relying on the
backend, use recursive scan similar to `rclone size` to compute the total
used space. However, this is ineffective and should be used as a last resort.

Before this change options were read and set in native format. This
means for example nanoseconds for durations or an integer for
enumerated types, which isn't very convenient for humans.
This change enables these types to be set with a string with the
syntax as used in the command line instead, so `"10s"` rather than
`10000000000` or `"DEBUG"` rather than `8` for log level.
The initial ':' is included in the ad-hoc remote name, but is illegal character
in Windows path. Replacing it with '^', which is legal in filesystems but illegal
in regular remote names, so name conflict is avoided.
Fixes#4544
Before this change using --vfs-cache-mode full and --buffer-size 0
together caused the vfs downloader to open more and more downloaders.
This is fixed by introducing a minimum size of 1M for the window to
look for an existing downloader.
Fixes#4892
