Before this change, if writing to a local backend with --metadata and
--links, if the incoming metadata contained mode or ownership
information then rclone would apply the mode/ownership to the
destination of the link not the link itself.
This fixes the problem by using the link safe sycall variants
lchown/fchmodat when --links and --metadata is in use. Note that Linux
does not support setting permissions on symlinks, so rclone emits a
debug message in this case.
This also fixes setting times on symlinks on Windows which wasn't
implemented for atime, mtime and was incorrectly setting the target of
the symlink for btime.

Before this change, --copy-links erroneously behaved like --links when using cloning
on macOS, and cloning was not supported at all when using --links.
After this change, --copy-links does what it's supposed to, and takes advantage of
cloning when possible, by copying the file being linked to instead of the link
itself.
Cloning is now also supported in --links mode for regular files (which benefit
most from cloning). symlinks in --links mode continue to be tossed back to be
handled by rclone's special translation logic.

In this commit we merged an unreliable test
e053c8a1c0 copy: fix nil pointer dereference when corrupted on transfer with nil dst
It is a good idea but very hard to implement so it always works.
Hence this disables it for the moment.
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.

Before this change using /path/to/file.rclonelink would not find the
file when using -l/--links.
This fixes the problem by doing another stat call if the file wasn't
found without the suffix if -l/--links is in use.
It will also give an error if you refer to a symlink without its
suffix which will not work because the limit to a single file
filtering will be using the file name without the .rclonelink suffix.
need ".rclonelink" suffix to refer to symlink when using -l/--links
Before this change it would use the symlink as a directory which then
would fail when listed.

Before this fix, a dangling symlink was erroring the sync. It was
writing an ERROR log and causing rclone to exit with an error. The
List method wasn't returning an error though.
This fix makes sure that we don't log or report a global error on a
file/directory that has been excluded.
This feature was first implemented in:
a61d219bc local: fix -L/--copy-links with filters missing directories
Then fixed in:
8d1fff9a8 local: obey file filters in listing to fix errors on excluded files
This commit also adds test cases for the failure modes of those commits.
See #6376
In this commit
8d1fff9a82 local: obey file filters in listing to fix errors on excluded files
We started using filters in the local backend so the user could short
circuit troublesome files/directories at a low level.
However this caused a number of integration tests to fail. This turned
out to be in backends wrapping the local backend. For example the
combine backend test failed because it changes the paths passed to the
local backend so they no longer match the paths in the current filter.
To fix this, a new feature flag `FilterAware` was added and the
UseFilter context flag is only passed to backends which support it. As
the wrapping backends don't support the flag, this fixes the problems
in the integration tests.
In future the wrapping backends could modify the active filters to
match the path modifications and then they could set the FilterAware
flag.
See #6376
Before this fix if a file was updated, but to the same length and
timestamp then the local backend would return the wrong (cached)
hashes for the object.
This happens regularly on a crypted local disk mount when the VFS
thinks files have been changed but actually their contents are
identical to that written previously. This is because when files are
uploaded their nonce changes so the contents of the file changes but
the timestamp and size remain the same because the file didn't
actually change.
This causes errors like this:
ERROR: file: Failed to copy: corrupted on transfer: md5 crypted
hash differ "X" vs "Y"
This turned out to be because the local backend wasn't clearing its
cache of hashes when the file was updated.
This fix clears the hash cache for Update and Remove.
It also puts a src and destination in the crypt message to make future
debugging easier.
Fixes#4031
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 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.
Before this change rclone returned the size from the Stat call of the
link. On Windows this reads as 0 always, however on unix it reads as
the length of the text in the link. This caused errors like this when
syncing:
Failed to copy: corrupted on transfer: sizes differ 0 vs 13
This change causes Windows platforms to read the link and use that as
the size of the link instead of 0 which fixes the problem.
- 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.
This unifies the 3 methods of reading config
* command line
* environment variable
* config file
And allows them all to be configured in all places. This is done by
making the []fs.Option in the backend registration be the master
source of what the backend options are.
The backend changes are:
* Use the new configmap.Mapper parameter
* Use configstruct to parse it into an Options struct
* Add all config to []fs.Option including defaults and help
* Remove all uses of pflag
* Remove all uses of config.FileGet
