A stale lock may be refreshed if it continues to exist until after a
replacement lock has been created. This ensures that a repository was
not unlocked in the meantime.
Conceptually the backend configuration should be validated when creating
or opening the backend, but not when filling in information from
environment variables into the configuration.
This unified construction removes most backend-specific code from
global.go. The backend registry will also enable integration tests to
use custom backends if necessary.
In order to change the backend initialization in `global.go` to be able
to generically call cfg.ApplyEnvironment() for supported backends, the
`interface{}` returned by `ParseConfig` must contain a pointer to the
configuration.
An alternative would be to use reflection to convert the type from
`interface{}(Config)` to `interface{}(*Config)` (from value to pointer
type). However, this would just complicate the type mess further.
The index used by restic consumes a major part of the total memory
usage. This leads to an unnecessarily large amount of memory that
contains ephemeral objects that are only used for a short time.
Modifies format module to add options for human readable storage size formatting, using size parsing already in ui/format.
Cmd flag --human-readable added to ls and find commands.
Additional option added to formatNode to support printing size in regular or new human readable format
The tests are now split into individual files for each command. The
separation isn't perfect as many tests make use of multiple commands. In
particular `init`, `backup`, `check` and `list` are used by a larger
number of test cases.
Most tests now reside in files name cmd_<name>_integration_test.go. This
provides a certain indication which commands have significant test
coverage.
Use the logging methods from testing.TB to make use of tb.Helper(). This
allows the tests to log the filename and line number in which the test
helper was called. Previously the test helper was logged which is rarely
useful.
