Depending on how long an operation takes to fail, the total retry
duration can currently vary between 1.5 and 15 minutes. In particular
for temporarily interrupted network connections, the former timeout is
too short. Thus always use a limit of 15 minutes.
The StdioWrapper type is really just a pair of io.WriteClosers, so
remove it in favor of a function that returns two of those. Test
coverage increases because the removed code was not tested.
RemoveUnpacked will eventually block removal of all filetypes other than
snapshots. However, getting there requires a major refactor to provide
some components with privileged access.
LoadRaw also includes improved context cancellation handling similar to the
implementation in repository.LoadUnpacked.
The removed cache backend test will be added again later on.
We don't need `error` here: the only existing implementation
of `ErrorHandler` always call `Backup.Error` and all
implementations of `Backup.Error` always return nil.
This commit adds support for specifying the `--host` option via the `RESTIC_HOST` environment variable. This is done by extending option processing in `cmd_backup.go` and for `restic.SnapshotFilter` in `find.go`.
In order to evaluate the keep reasons for snapshots, there should be also the id's
to compare it with snapshots within the keep object. (See also Issue #3117)
In order to avoid output parameters also changed function addJSONSnapshots to asJSONSnapshots
As `ls` reads data from the repository, it must acquire a read lock
unless `--no-lock` was specified. The old behavior is equivalent to `ls
--no-lock`.
The new functions much better convey the intent behind the lock
request. This allows cleanly integrating noLock (for read) and dryRun
(write/exclusive) handling.
There are only minor changes to existing behavior with two exceptions:
- `tag` no longer accepts the `--no-lock` flag. As it replaces files in
the repository, this always requires an exclusive lock.
- `debug examine` now returns an error if both `--extract-pack` and
`--no-lock` are given.
Add new generic_attributes attribute in Node.
Use the generic attributes to add support for creation time and file attributes like hidden, readonly, encrypted in windows. Handle permission errors for readonly files in windows.
Handle backup and restore of encrypted attributes using windows system calls.
The previous code only ran cleanup (lock release for example) on SIGINT. For
anyone running restic in a container, the signal is going to be SIGTERM which
means containerized execution would leave locks behind.
While this could be addressed via interposing dumb-init to translate the signal,
a `kill` invocation is going to default to SIGTERM, so the same problem exists
for non container users.

Other commands like key list and key remove show the key's ID.
Showing the ID here lets users easily reuse the ID as a key hint for subsequent
commands.
In particular, a key hint is needed when the repository has many keys - otherwise
opening the repository may fail with "Fatal: maximum number of keys reached" even
when a proper password is provided.
Fixes#4656
NCDU (NCurses Disk Usage) is a tool to analyse disk usage of directories.
It has an option to save a directory tree and analyse it later.
This patch adds an output option to the ls command.
A snapshot can be seen with
`restic ls latest --ncdu | ncdu -f -`

Currently, the cmd/restic package contains a significant amount of code
that modifies repository internals. This code should in the mid-term
move into the repository package.
LoadBlobsFromPack is now part of the repository struct. This ensures
that users of that method don't have to deal will internals of the
repository implementation.
The filerestorer tests now also contain far fewer pack file
implementation details.
It was only used in two places:
- stats: apparently as a minor performance optimization, which is
unlikely to be important
- find: filtered directories would be ignored. However, this
optimization missed that it is possible that two directories have the
exact same content. Such directories would be incorrectly ignored too.
Example:
```
mkdir test test/a test/b
restic backup test
restic find latest test/b
-> incorrectly does not return anything
```
Thus, remove the functionality as it's apparently too complex to use
correctly.
When using `RESTIC_REPOSITORY_FILE` in combination with `restic init`,
the repository is missing in the output:
```
$ restic init
created restic repository 3c872be20f at
[...]
```
This is due to the code using `gopts.Repo`, which is empty in this case.
This change better resembles the output generated by `Snapshot.String()`,
which includes both username and hostname.

This introduces a new modifier to the output of the diff command. It
appears whenever two files being compared only differ in their content
but not in their metadata. As far as we know, under normal
circumstances, this should only ever happen if some kind of bitrot has
happened in the source file. The prerequisite for this detection to work
is that the right-side snapshot of the comparison has been created with
"backup --force".
Adds
* snapshotMetadataArgs, which holds the new metadata as strings parsed from
the command line
* snapshotMetadata, which holds the new metadata converted to the
correct types
Bug #1681 suggests that restic should not be nice to user and should
refrain from creating a mountpoint if it does not exist. Nevertheless,
it currently opens the repository before checking for the mountpoint's
existence. In the case of large or remote repositories, this process
can be time-consuming, delaying the inevitable outcome.
/restic mount --repo=REMOTE --verbose /tmp/backup
repository 33f14e42 opened (version 2, compression level max)
[0:38] 100.00% 162 / 162 index files loaded
Mountpoint /tmp/backup doesn't exist
stat /tmp/backup: no such file or directory
real 0m39.534s
user 1m53.961s
sys 0m3.044s
In this scenario, 40 seconds could have been saved if the nonexistence
of the path had been verified beforehand.
This patch relocates the mountpoint check to the beginning of the
runMount function, preceding the opening of the repository.
/restic mount --repo=REMOTE --verbose /tmp/backup
Mountpoint /tmp/backup doesn't exist
stat /tmp/backup: no such file or directory

The behavior of the new option should reflect the behavior of normal backups: when the command exit code is zero and there is no output in the stdout, emit a warning but create the snapshot. This commit fixes the integration tests and the ReadCloserCommand struct.
In order to determine whether to save a snapshot, we need to capture the exit code returned by a command. In order to provide a nice error message, we supply stderr as well.

It acts similar to --stdin but reads its data from the stdout of the given command instead of os.Stdin.
Signed-off-by: Sebastian Hoß <seb@xn--ho-hia.de>
In order to run with --stdin-from-command we need to short-circuit some functions similar to how it is handled for the --stdin flag. The only difference here is that --stdin-from-command actually expects that len(args) should be greater 0 whereas --stdin does not expect any args at all.

This new flag is added to the backup subcommand in order to allow restic to control the execution of a command and determine whether to save a snapshot if the given command succeeds.

inodes are only unique within a device. Use the HardlinkIndex from the
restorer instead of the custom (broken) hashmap to correctly account for
both inode and deviceID.
For now, the guide is only shown if the blob content does not match its
hash. The main intended usage is to handle data corruption errors when
using maximum compression in restic 0.16.0
This introduces the inode attribute to the JSON output emitted for nodes
in `ls` and matches in `find`. There doesn't seem to be any discernible
reason to omit the inode and it can be useful in scripting scenarios.
