The GlobalOptions struct now embeds a backend.TransportOptions, so it
doesn't need to construct one in open and create. The upload and
download limits are similarly now a struct in internal/limiter that is
embedded in GlobalOptions.
github.com/pkg/errors is no longer getting updates, because Go 1.13
went with the more flexible errors.{As,Is} function. Use those instead:
errors from pkg/errors already support the Unwrap interface used by 1.13
error handling. Also:
* check for io.EOF with a straight ==. That value should not be wrapped,
and the chunker (whose error is checked in the cases changed) does not
wrap it.
* Give custom Error methods pointer receivers, so there's no ambiguity
when type-switching since the value type will no longer implement error.
* Make restic.ErrAlreadyLocked private, and rename it to
alreadyLockedError to match the stdlib convention that error type
names end in Error.
* Same with rest.ErrIsNotExist => rest.notExistError.
* Make s3.Backend.IsAccessDenied a private function.
cleanup handlers run in the order in which they are added. As Go calls
init() functions in lexical order, the cleanup handler from global.go
was registered before that from lock.go, which is the correct order.
Make this order explicit to ensure that this won't break accidentally.
Closes#3595
Choosing to include `stdoutIsTerminal()` as:
- all other instances with `!opts.JSON` do so
- this likely will not affect anything, especially when autorun
- this seems to not be a meaningful enough summary
to include in auto-backup reports
JSON is still likely not guaranteed to work and this is a suboptimal
solution to this. Ideally, #1804 should refactor all print statements,
and define+document(+handle) when stdoutIsTerminal() should be used.
Else, it may end up more inconsistent and bulky
(duplicate lines, longer files).
* PrintProgress no longer does unnecessary Sprintf calls, and performs
fewer allocations in general
* newProgressMax's callback checks whether the terminal supports
line updates once instead of once per call
* the callback looks up the terminal width once per call instead of
twice (on Windows)
* the status shortening now uses the Unicode-aware version from
internal/ui/termstatus (future-proofing)
Previously the progress bar / status update interval used
stdoutIsTerminal to determine whether it is possible to update the
progress bar or not. However, its implementation differed from the
detection within the backup command which included additional checks to
detect the presence of mintty on Windows. mintty behaves like a terminal
but uses pipes for communication.
This adds stdoutCanUpdateStatus() which calls the same terminal detection
code used by backup. This ensures that all commands consistently switch
between interactive and non-interactive terminal mode.
stdoutIsTerminal() now also returns true whenever stdoutCanUpdateStatus()
does so. This is required to properly handle the special case of mintty.
As an alternative to -r, this allows to read the repository URL
from a file in order to prevent certain types of information leaks,
especially for URLs containing credentials.
Fixes#1458, fixes#2900.
Add a copy command to copy snapshots between repositories. It allows the user
to specify a destination repository, password, password-file, password-command
or key-hint to supply the necessary details to open the destination repository.
You need to supply a list of snapshots to copy, snapshots which already exist
in the destination repository will be skipped.
Note, when using the network this becomes rather slow, as it needs to read the
blocks, decrypt them using the source key, then encrypt them again using the
destination key before finally writing them out to the destination repository.
