This removes the requirement on `restic self-update --output` to point
to a path of an existing file, to overwrite. In case the specified
path does exist we still want to verify that it's a regular file,
rather than a directory or a device, which gets overwritten.
We also want to verify that a path to a new file exists within an
existing directory. The alternative being running into that issue
after the actual download, etc has completed.
While at it I also replace `errors.Errorf` with the more appropriately
verbose `errors.Fatalf`.
Resolves #2491
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.
When the backup is interrupted for some reason while the scanner is
still active this could lead to a deadlock. Interruptions are triggered
by canceling the context object used by both the backup progress UI and
the scanner. It is possible that a context is canceled between the
respective check in the scanner and it calling the `ReportTotal` method
of the UI. The latter method sends a message to the UI goroutine.
However, a canceled context will also stop that goroutine, which can
cause the channel send operation to block indefinitely.
This is resolved by adding a `closed` channel which is closed once the
UI goroutine is stopped and serves as an escape hatch for reported UI
updates.
This change covers not just the ReportTotal method but all potentially
affected methods of the progress UI implementation.
This allows creating multiple repositories with identical chunker
parameters which is required for working deduplication when copying
snapshots between different repositories.
Previously the directory stats were reported immediately after calling
`SaveDir`. However, as the latter method saves the tree asynchronously
the stats were still initialized to their nil value. The stats are now
reported via a callback similar to the one used for the fileSaver.
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.
Do not lock the repository if --no-lock global flag is set. This allows
to mount repositories which are archived on a read only system.

- Add Open() functionality to dir
- only access index for blobs when file is read
- Implement NodeOpener and put one-time file stuff there
- Add comment about locking as suggested by bazil.org/fuse
=> Thanks at Michael Eischer for suggesting the last two improvements
In the Google Cloud Storage backend, support specifying access tokens
directly, as an alternative to a credentials file. This is useful when
restic is used non-interactively by some other program that is already
authenticated and eliminates the need to store long lived credentials.
The access token is specified in the GOOGLE_ACCESS_TOKEN environment
variable and takes precedence over GOOGLE_APPLICATION_CREDENTIALS.
The backup command used to return a zero exit code as long as a snapshot
could be created successfully, even if some of the source files could not
be read (in which case the snapshot would contain the rest of the files).
This made it hard for automation/scripts to detect failures/incomplete
backups by looking at the exit code. Restic now returns the following exit
codes for the backup command:
- 0 when the command was successful
- 1 when there was a fatal error (no snapshot created)
- 3 when some source data could not be read (incomplete snapshot created)
- The SaveBlob method now checks for duplicates.
- Moves handling of pending blobs to MasterIndex.
-> also cleans up pending index entries when they are saved in the index
-> when using SaveBlob no need to care about index any longer
- Always check for full index and save it when storing packs.
-> removes the need of an index uploader
-> also removes the verbose "uploaded intermediate index" messages
- The Flush method now also saves the index
- Fix race condition when checking and saving full/non-finalized indexes
In a damaged repository with a missing blob, the error message tried to
dereference the subtreeID field of the current node, which is a file
however. Said field is set to nil for a file thus causing a segfault
when dereferenced.
Fix this by using the actual parentTreeID.
The username and hostname for new keys can be specified with the new
--user and --host flags, respectively. The flags are used only by the
`key add` command and are otherwise ignored.
This allows adding keys with for a desired user and host without having
to run restic as that particular user on that particular host, making
automated key management easier.

The `dump`, `find`, `forget`, `ls`, `mount`, `restore`, `snapshots`,
`stats` and `tag` commands will now take into account multiple
`--host` and `-H` flags.
Much simpler implementation that guarantees each required pack
is downloaded only once (and hence does not need to manage
pack cache). Also improves large file restore performance.

This commit adds support for cross-compiling Restic for ppc64le
as part of the release process.
Add a new file: changelog/unreleased/issue-2277
Modifies: helpers/build-release-binaries/main.go
Modifies: run_integration_tests.go
Restic used to quit if the repository password was typed incorrectly once.
Restic will now ask the user again for the repository password if typed incorrectly.
The user will now get three tries to input the correct password before restic quits.
Return valid directory info from Lstat() for parent directories of the
specified filename. Previously only "/" and "." were valid directories.
Also set directory mode as this is checked by archiver.
Closes #2063
Sometimes restic gets bogus timestamps which cannot be converted to
JSON, because the stdlib JSON encoder returns an error if the year is
not within [0, 9999]. We now make sure that we at least record _some_
timestamp and cap the year either to 0000 or 9999. Before, restic would
refuse to save the file at all, so this improves the status quo.
This fixes #2174 and #1173
With this change it is possible to dump a folder to stdout as a tar. The
It can be used just like the normal dump command:
`./restic dump fa97e6e1 "/data/test/" > test.tar`
Where `/data/test/` is a a folder instead of a file.
Reading the password from non-terminal stdin used io.ReadFull with a
byte slice of length 1000.
We are now using a Scanner to read one line of input, independent of its
length.
Additionally, if stdin is not a terminal, the password is read only
once instead of twice (in an effort to detect typos).
Fixes #2203

This commit changes the logic slightly: checking the permissions in the
fuse mount when nobody else besides the current user can access the fuse
mount does not sense. The current user has access to the repo files in
addition to the password, so they can access all data regardless of what
the fuse mount does.
Enabling `--allow-root` allows the root user to access the files in the
fuse mount, for this user no permission checks will be done anyway.
The code now enables `DefaultPermissions` automatically when
`--allow-other` is set, it can be disabled with
`--no-default-permissions` to restore the old behavior.
