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.
The failure is this which is not reproducable locally, only on the CI
servers.
--- FAIL: TestMount/CacheMode=minimal/TestWriteFileOverwrite (1.01s)
fs.go:351:
Error Trace: fs.go:351
write.go:65
Error: Received unexpected error:
open E:testwrite: The request could not be performed because of an I/O device error.
Test: TestMount/CacheMode=minimal/TestWriteFileOverwrite
The corresponding ERROR from the log is this:
ERROR : IO error: truncate C:\Users\runneradmin\AppData\Local\rclone\vfs\local\C\Users\RUNNER~1\AppData\Local\Temp\rclone298719627\testwrite: Access is denied.
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.
Before this change `rclone mount` would give this error on FreeBSD
mount helper error: mount_fusefs: -o timeout=: option not supported
Because the default value for FreeBSD was set to 15m for
--daemon-timeout and that FreeBSD does not support the timeout option.
This change sets the default for --daemon-timeout to 0 on FreeBSD
which fixes the problem.
Fixes#3610
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.
Fixes#3381
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions
Context propagation is needed for stopping transfers and passing other
request-scoped values.
Before this fix rclone didn't wait for the stats to be finished before
exiting, so the final new line was never printed.
After this change rclone will wait for the stats routine to cease
before exiting.
OSX FUSE only supports 32 bit number of blocks which means that block
counts have been wrapping. This causes f_bavail to be 0 which in turn
causes problems with programs like borg backup.
Fixes#2356
By default the timeout is 60s which isn't long enough for long
transactions. The symptoms are rclone just quitting for no reason.
Supplying the --daemon-timeout flag fixes this causing the kernel to
wait longer for rclone.
Before this change we would unconditionally set the OSXFUSE options
noappledouble and noapplexattr.
However the noapplexattr options caused problems with copies in the
Finder.
Now the default for noapplexattr is false so we don't add the option
by default and the user can override the defaults using the
--noappledouble and --noapplexattr flags.
Before this change rclone would set the volume name from the
remote:path normally. However this has `:` and `/` in which make it
difficult to use in macOS.
Now rclone will remove the special characters and replace them with
spaces. It also allows the volume name to be set with the --volname
flag.
This stops the cache cleaner running unnecessarily and saves
resources.
This also helps with issue #2227 which was caused by a second mount
deleting objects in the first mounts cache.
The written out list of tests was replaced with a nested test for
mount and cmount. The tests for each VFS cache mode were also replaced
with nested tests which makes the output and the code much cleaner.
This flag allows the attribute caching in the kernel to be controlled.
The default is 0s - no caching - which is recommended for filesystems
which can change outside the control of the kernel.
Previously this was at the default meaning it was 60s for mount and 1s
for cmount. This showed strange effects when files changed on the
remote not via the kernel. For instance Caddy would serve corrupted
files for a while when serving from an rclone mount when a file
changed on the remote.
The purpose of this is to make it easier to maintain and eventually to
allow the rclone backends to be re-used in other projects without
having to use the rclone configuration system.
The new code layout is documented in CONTRIBUTING.
The filesystem does a certain amount of things asynchronously waiting
for the file to be released after writing it means everything should
be in a consistent state.
* Tests for VFS layer
* Small fixes found during testing
* Fix Close, Flush and Release behaviour for ReadFileHandle and WriteFileHandle
* Fix nil object bugs on File
In certain circumstances if an upload failed then the mount could hang
indefinitely. This was fixed by closing the read pipe after the Put
completed. This will cause the write side to return a pipe closed
error fixing the hang.
Fixes#1498
This is a fix left over from the v2 conversion. Dropbox ignores the
client modification on an incoming file if it was identical to the
existing file. This change deletes the existing file first before
re-uploading the new one.
Normally mount/cmount use `-o ro` to get the kernel to mark the fs as
read only. However this is ignored by WinFsp, so in addition if
`--read-only` is in effect then return EROFS ("Read only File System")
from all methods which attempt to modify something.
