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.
Closes #4506

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.
A delayed lock refresh could send a signal on the `refreshed` channel
while the `monitorLockRefresh` goroutine waits for a reply to its
`refreshLockRequest`. As the channels are unbuffered, this resulted in a
deadlock.
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.
