Replace AuthRequired bool with NoAuth bool on the rc.Call struct and
flip the auth check logic. Previously endpoints were unauthenticated
by default and had to opt in with AuthRequired: true, which led to
security vulnerabilities when developers forgot to set the flag.
Now all endpoints require authentication by default. Only explicitly
safe read-only endpoints are marked with NoAuth: true:
- rc/noop
- rc/error
- rc/list
- core/version
- core/stats
- core/group-list
- core/transferred
- core/du
- cache/stats
- vfs/list
- vfs/stats
- vfs/queue
- job/status
- job/list

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.
- 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 implements a remote control protocol activated with the --rc flag
and a new command `rclone rc` to use that interface.
Still to do
* docs - need finishing
* tests
