Enhancement: Improve handling of ErrDot errors in rclone and sftp backends
|
|
|
|
|
|
|
|
|
|
Since Go 1.19, restic can no longer implicitly run relative executables which
|

|
|
|
are found in the current directory (e.g. `rclone` if found in `.`). This is a
|
|
|
|
|
security feature of Go to prevent against running unintended and possibly
|
2022-09-20 19:26:01 +00:00
|
|
|
harmful executables.
|
|
|
|
|
|
|
|
|
|
The error message for this was just "cannot run executable found relative to
|
|
|
|
|
current directory". This has now been improved to yield a more specific error
|
|
|
|
|
message, informing the user how to explicitly allow running the executable
|
|
|
|
|
using the `-o rclone.program` and `-o sftp.command` extended options with `./`.
