306a29980a Print stacktrace in SIGINT handler if RESTIC_DEBUG_STACKTRACE_SIGINT set
The builtin mechanism to capture a stacktrace in Go is to send a SIGQUIT
to the running process. However, this mechanism is not avaiable on
Windows. Thus, tweak the SIGINT handler to dump a stacktrace if the
environment variable `RESTIC_DEBUG_STACKTRACE_SIGINT` is set.

179e11c2ae Increase timeouts for lock refresh tests
When saving files to the local backend, in some cases the used fsync
calls are slow enough to cause the tests to time out. Thus, increase the
test timeouts as a stopgap measure until we can use the mem backend for
these tests.

8e1e3844aa backend: factor out connection limiting and parameter validation
The SemaphoreBackend now uniformly enforces the limit of concurrent
backend operations. In addition, it unifies the parameter validation.

The List() methods no longer uses a semaphore. Restic already never runs
multiple list operations in parallel.

By managing the semaphore in a wrapper backend, the sections that hold a
semaphore token grow slightly. However, the main bottleneck is IO, so
this shouldn't make much of a difference.

The key insight that enables the SemaphoreBackend is that all of the
complex semaphore handling in `openReader()` still happens within the
original call to `Load()`. Thus, getting and releasing the semaphore
tokens can be refactored to happen directly in `Load()`. This eliminates
the need for wrapping the reader in `openReader()` to release the token.

97274ecabd cmd, restic: Refactor and fix snapshot filtering
This turns snapshotFilterOptions from cmd into a restic.SnapshotFilter
type and makes restic.FindFilteredSnapshot and FindFilteredSnapshots
methods on that type. This fixes #4211 by ensuring that hosts and paths
are named struct fields instead of unnamed function arguments in long
lists of such.

Timestamp limits are also included in the new type. To avoid too much
pointer handling, the convention is that time zero means no limit.
That's January 1st, year 1, 00:00 UTC, which is so unlikely a date that
we can sacrifice it for simpler code.

Add a global option --retry-lock
Fixes restic#719

If the option is passed, restic will wait the specified duration of time
and retry locking the repo every 10 seconds (or more often if the total
timeout is relatively small).

- Play nice with json output
- Reduce wait time in lock tests
- Rework timeout last attempt
- Reduce test wait time to 0.1s
- Use exponential back off for the retry lock
- Don't pass gopts to lockRepo functions
- Use global variable for retry sleep setup
- Exit retry lock on cancel
- Better wording for flag help
- Reorder debug statement
- Refactor tests
- Lower max sleep time to 1m
- Test that we cancel/timeout in time
- Use non blocking sleep function
- Refactor into minDuration func

Reinstate selfupdate tag to make builds without self-update work
Revert what seems to be a typo introduced as part of the fix for #2041
in 2018 7d0f2eaf24.

`xbuild` does not look like a go build/tag keyword to me, I failed to
find documentation for it and using `go install -tags '!selfupdate' ...`
has no effect, i.e. self-update code is still compiled.

`+build` however works;  updating the OpenBSD port/binary package
security/restic to apply this PR works as expected:

```
	$ restic help | grep self
	$ restic self-update
	unknown command "self-update" for "restic"
```

(Using `go:build` now as per restic's style and gofmt.)

Previously, using `restic-0.14.0p1` on OpenBSD/amd64 7.2-current would
check for a newer version and probably attempt replacing the system wide
root-owned executable (on a read-only filesystem) as unprivileged user:

```
	$ restic version
	restic 0.14.0 compiled with go1.19.2 on openbsd/amd64
	$ restic help | grep self
	  self-update   Update the restic binary
	$ restic self-update
	writing restic to /usr/local/bin/restic
	find latest release of restic at GitHub
	restic is up to date
```

(It never tried to actually write besaid path;  doing so would fail, so
the current message can be considered misleading.)

14aa6f2a00 add --disable-scanner to backup command
The scanner process has only cosmetic effect for the progress printer,
and can be disabled without impacting functionality when the user does
not need an estimate of completion.

In many cases the scanner process can provide beneficial priming of
the file system cache, so as general advice it should not be disabled.
However, tests have shown that backup of NFS and fuse based filesystems,
where stat(2) is relatively expensive, can be significantly faster
without the scanner.

38b2e9b42c rewrite: Always set the Original field in a rewritten snapshot
The Original field is meant to remember the original snapshot id if e.g.
changing its tags. It was only set by the `rewrite` command if it was
not set previously. However, a rewritten snapshot is potentially rather
different from the original snapshot. Thus just always set the Original
field. This also makes it easier to later on detect and potentially
remove the original snapshots.

05651d6d4f prune: Correctly count used/duplicate blobs for partially compressed repos
Counting the first occurrence of a duplicate blob as used and counting
all other as duplicates, independent of which instance of the blob is
kept, is only accurate if all copies of the blob have the same size. This
is no longer the case for a repository containing both compressed and
uncompressed blobs.

Thus for duplicated blobs first count all instances as duplicates and
then subtract the actually used instance later on.

As long as only a small fraction of the data in a repository is

As golang maps do not shrink their memory usage, just copy the contents
over to a new map. However, only copy the map if the cleanup removed at

99547518cd lock: fix flaky TestLockFailedRefresh
The comparison of the current time and the last lock refresh were using

second, the associated number truncation can cause the test to take
longer than once second and thus to fail.

Switch to nanoseconds to avoid this problem. This also slightly speeds
up the test.

d92957dd78 lock: Implement strict lock expiry monitoring
Restic continued e.g. a backup task even when it failed to renew the
lock or failed to do so in time. For example if a backup client enters
standby during the backup this can allow other operations like `prune`
to run in the meantime (after calling `unlock`). After leaving standby
the backup client will continue its backup and upload indexes which
refer pack files that were removed in the meantime.

This commit introduces a goroutine explicitly monitoring for locks that
are not refreshed in time. To simplify the implementation there's now a
separate goroutine to refresh the lock and monitor for timeouts for each
lock. The monitoring goroutine would now cause the backup to fail as the
client has lost it's lock in the meantime.

The lock refresh goroutines are bound to the context used to lock the
repository initially. The context returned by `lockRepo` is also
cancelled when any of the goroutines exits. This ensures that the
context is cancelled whenever for any reason the lock is no longer
refreshed.

985722b102 Remove ctx from globalOptions
Previously the global context was either accessed via gopts.ctx,
stored in a local variable and then used within that function or
sometimes both. This makes it very hard to follow which ctx or a wrapped
version of it reaches which method.

Thus just drop the context from the globalOptions struct and pass it
explicitly to every command line handler method.

We can either preallocate storage for a file or sparsify it. This

approximation, hide it behind a `--sparse` parameter.

`init` and `copy` use `--repo2` with two different meaning which has
proven to be confusing for users. `--from-repo` now consistently marks a
source repository from which data is read. `--repo` is now always the
target/destination repository.

6f53ecc1ae adapt workers based on whether an operation is CPU or IO-bound
Use runtime.GOMAXPROCS(0) as worker count for CPU-bound tasks,
repo.Connections() for IO-bound task and a combination if a task can be
both. Streaming packs is treated as IO-bound as adding more worker
cannot provide a speedup.

Typical IO-bound tasks are download / uploading / deleting files.
Decoding / Encoding / Verifying are usually CPU-bound. Several tasks are
a combination of both, e.g. for combined download and decode functions.
In the latter case add both limits together. As the backends have their
own concurrency limits restic still won't download more than
repo.Connections() files in parallel, but the additional workers can
decode already downloaded data in parallel.

120ccc8754 repository: Rework blob saving to use an async pack uploader
Previously, SaveAndEncrypt would assemble blobs into packs and either
return immediately if the pack is not yet full or upload the pack file
otherwise. The upload will block the current goroutine until it
finishes.

Now, the upload is done using separate goroutines. This requires changes
to the error handling. As uploads are no longer tied to a SaveAndEncrypt
call, failed uploads are signaled using an errgroup.

To count the uploaded amount of data, the pack header overhead is no
longer returned by `packer.Finalize` but rather by
`packer.HeaderOverhead`. This helper method is necessary to continue
returning the pack header overhead directly to the responsible call to
`repository.SaveBlob`. Without the method this would not be possible,
as packs are finalized asynchronously.

8bdfcf779f restic prune: Merge three loops over the index
There were three loops over the index in restic prune, to find
duplicates, to determine sizes (in pack.Size) and to generate packInfos.
These three are now one loop. This way, prune doesn't need to construct
a set of duplicate blobs, pack.Size doesn't need to contain special
logic for prune's use case (the onlyHdr argument) and pack.Size doesn't
need to construct a map only to have it immediately transformed into a
different map.

Some quick testing on a 160GiB local repo doesn't show running time or
memory use of restic prune --dry-run changing significantly.

f92ecf13c9 all: Move away from pkg/errors, easy cases
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.

dbbeac7174 prune: Add unsafe option to recover from no free space
The new option allows prune to operate with nearly no scratch space by only removing
no longer necessary pack files and first deleting the index before
rebuilding it. By first deleting the index it becomes safe to just
delete no longer necessary pack files. However, as a downside there's
now the risk that the repository becomes inaccessible if prune fails.

To recover from that problem a user might have to manually delete the
repository index and then run (a full) `rebuild-index` again.

As an exception prune is still allowed to load the index before
snapshots, as it uses exclusive locks. In case of problems with locking
it is also better to load snapshots created after loading the index, as
this will lead to a prune sanity check failure instead of a broken snapshot.

Nodes in trees were always printed with a `+` in diff, regardless of
whether or not a dir was added or removed. Let's use the mode we were
passed in printDir().

676d5d498c doc: Update forget security considerations and thread model 2022-03-23 23:12:19 +01:00
Luc Gommans
9c1d49e312 Document "forget" security considerations and add references
Removing data based on a policy when the attacker had the opportunity to
add data to your repository comes with some considerations. This is
added to the 060_forget.rst documentation.

That document is also updated to reflect that restic now considers
the current system time while running "forget".

References to the security considerations section are added:
- In `restic forget --help`
- In the threat model (design.rst)
- In the (030) setup section where an append-only setup is referenced

A reference is also to be added to the `rest-server` readme's
append-only paragraph (see my fork).

This commit also resolves a typo (amount->number for countable noun),
changes a password length recommendation into the metric that
actually matters when creating passwords (entropy) since I was editing
these doc files anyway, and updates the outdated copyright year in
`conf.py`.

Some wording in 060_forget (line 21..22) was changed to clarify what
"forget" and "prune" do, to try and avoid the apparent misconception
that "forget" does not remove any data.

058dfc20da Avoid choosing parent snapshot newer than time of current snapshot
Currently, `restic backup` (if a `--parent` is not provided)
will choose the most recent matching snapshot as the parent snapshot.
This makes sense in the usual case,
where we tag the snapshot-being-created with the current time.

However, this doesn't make sense if the user has passed `--time`
and is currently creating a snapshot older than the latest snapshot.
Instead, choose the most recent snapshot
which is not newer than the snapshot-being-created's timestamp,
to avoid any time travel.

Impetus for this change:
I'm using restic for the first time!
I have a number of existing BTRFS snapshots
I am backing up via restic to serve as my initial set of backups.
I initially `restic backup`'d the most recent snapshot to test,
then started backing up each of the other snapshots.
I noticed in `restic cat snapshot <id>` output
that all the remaining snapshots have the most recent as the parent.

Parallelize blob upload/download for restic copy
Currently restic copy will copy each blob from every snapshot serially,
which has performance implications on high-latency backends such as b2.

This commit introduces 8x parallelism for blob downloads/uploads which
can improve restic copy operations up to 8x for repositories with many
small blobs on b2.

This commit also addresses the TODO comment in the copyTree function.

A more thorough improvement of the restic copy performance can be found
in PR #3513

f92130d878 logging: quiet 'removing n old cache dirs'
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).

a144c986f2 backup: Reenable JSON status updates with redirected output
After the refactoring status updates were no longer printed in quiet
mode or when the output is not an interactive terminal. However, the
JSON output is often piped to e.g. another program. Thus, don't set the
update frequency to 0 in that case. The status updates are still
disabled for backup --quiet.

This also reduces the status update frequency to 60fps compared to a
potentially much higher value before the refactoring.

77bf148460 backup: add --dry-run/-n flag to show what would happen.
This can be used to check how large a backup is or validate exclusions.
It does not actually write any data to the underlying backend. This is
implemented as a simple overlay backend that accepts writes without
forwarding them, passes through reads, and generally does the minimal
necessary to pretend that progress is actually happening.

Fixes #1542

6c01078f3d find: support resolving multiple pack ids to blobs
Just passing the list of blobs to packsToBlobs would also work in most
cases, however, it could cause unexpected results when multiple pack
files have the same prefix. Forget found prefixes to prevent this.

fe43f53528 mount: enable fuse readahead
Apparently readahead was disabled by default. Enable readahead with the
Linux default size of 128kB. Larger values seem to have no effect.
This can speed up reading from the fuse mount by at least factor 5.

Speedup for a 1G random file stored in a local repository:
(Only one result shown, but times were quite stable, restarted restic
after each command)

2a92b68e65 cmd/snapshots: Add option to limit snapshots list
This patch adds a `--latest` option to limit snapshots list to the n
last snapshots. It is very similar to the `--last` one but does not
limit to one entry. It also deprecates the `--last` flag usage in
favor of `--latest 1`

Output example:

    $ restic snapshots --latest 2
    repository 0d3eb989 opened successfully, password is correct

5e6af77b7a Unify interactive terminal detection code
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.
