537b4c310a copy: Implement by reusing repack
The repack operation copies all selected blobs from a set of pack files
into new pack files. For prune the source and destination repositories
are identical. To implement copy, just use a different source and
destination repository.

cd190bee14 filter: short circuit if no negative patterns 2022-03-20 13:33:08 +01:00

2ee07ded2b filter: ability to use negative patterns
This is quite similar to gitignore. If a pattern is suffixed by an
exclamation mark and match a file that was previously matched by a
regular pattern, the match is cancelled. Notably, this can be used
with `--exclude-file` to cancel the exclusion of some files.

Like for gitignore, once a directory is excluded, it is not possible
to include files inside the directory. For example, a user wanting to
only keep `*.c` in some directory should not use:

    ~/work
    !~/work/*.c

But:

    ~/work/*
    !~/work/*.c

I didn't write documentation or changelog entry. I would like to get
feedback if this is the right approach for excluding/including files
at will for backups. I use something like this as an exclude file to
backup my home:

    $HOME/**/*
    !$HOME/Documents
    !$HOME/code
    !$HOME/.emacs.d
    !$HOME/games
    # [...]
    node_modules
    *~
    *.o
    *.lo
    *.pyc
    # [...]
    $HOME/code/linux/*
    !$HOME/code/linux/.git
    # [...]

There are some limitations for this change:

 - Patterns are not mixed accross methods: patterns from file are
   handled first and if a file is excluded with this method, it's not
   possible to reinclude it with `--exclude !something`.

 - Patterns starting with `!` are now interpreted as a negative
   pattern. I don't think anyone was relying on that.

 - The whole list of patterns is walked for each match. We may
   optimize later by exiting early if we know no pattern is starting
   with `!`.

5ec312ca06 sftp: Implement atomic uploads
Create a temporary file with a sufficiently random name to essentially
avoid any chance of conflicts. Once the upload has finished remove the
temporary suffix. Interrupted upload thus will be ignored by restic.

c6fd13425b remember the refreshed lock file even if removal failed
This ensures that restic won't create lots of new lock files without
deleting them later on.

In some cases a Delete operation on a backend can return a "File does
not exist" error even though the Delete operation succeeded. This can
for example be caused by request retries. This caused restic to forget
about the new lock file and continue trying to remove the old (already
deleted) lock file.

7080fed7ae Set O_NOATIME flag on Linux
Citing Kerrisk, The Linux Programming Interface:

    The O_NOATIME flag is intended for use by indexing and backup
    programs. Its use can significantly reduce the amount of disk
    activity, because repeated disk seeks back and forth across the
    disk are not required to read the contents of a file and to update
    the last access time in the file’s i-node[.]

restic used to do this, but the functionality was removed along with the
fadvise call in #670.

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.

50053a85d3 rest: Adjust http2 missing eof test to golang >= 1.17.3, >= 1.16.10
The missing eof with http2 when a response included a content-length
header but no data, has been fixed in golang 1.17.3/1.16.10. Therefore
just drop the canary test and schedule it for removal once go 1.18 is
required as minimum version by restic.

1b23675f21 cache --cleanup should handle directories created by restic check.
Because there is no guarantee that a cleanup of these directories will occur
after the "restic check", we extend the behavior to detect and manage these
specific cache directories and allow their cleanup too.

257740b0cc b2: Successful delete if file does not exist
When deleting a file, B2 sometimes returns a "500 Service Unavailable"
error but nevertheless correctly deletes the file. Due to retries in
the B2 library blazer, we sometimes also see a "400 File not present"
error. The retries of restic for the delete request then fail with
"404 File with such name does not exist.".

As we have to rely on request retries in a distributed system to handle
temporary errors, also consider a delete request to be successful if the
file is reported as not existing. This should be safe as B2 claims to
provide a strongly consistent bucket listing and thus a missing file
shouldn't mysteriously show up again later on.

634a9c162d Check cap instead of len in bloblru
restic dump uses bloblru.Cache to keep buffers alive, but also reuses
evicted buffers. That means large buffers may be used to store small
blobs, causing the cache to think it's using less memory than it
actually does.

In Go 1.17.1, maphash has become quite a bit faster than siphash, so we
can drop one third-party dependency. maphash is just an interface to the
standard Go map's hash function, which we already trust for other use
cases.

1d3e99f475 azure: check upload using md5 content hash
For files below 256MB this uses the md5 hash calculated while assembling
the pack file. For larger files the hash for each 100MB part is
calculated on the fly. That hash is also reused as temporary filename.
As restic only uploads encrypted data which includes among others a
random initialization vector, the file hash shouldn't be susceptible to
md5 collision attacks (even though the algorithm is broken).

9aa2eff384 Add plumbing to calculate backend specific file hash for upload
This enables the backends to request the calculation of a
backend-specific hash. For the currently supported backends this will
always be MD5. The hash calculation happens as early as possible, for
pack files this is during assembly of the pack file. That way the hash
would even capture corruptions of the temporary pack file on disk.

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

The golang http client does not return an error when a HTTP2 reply

This scenario can occur e.g. when using rclone when a file stored in a

Michael Eischer
80564a9bc9 Properly detect mintty output redirection
mintty on windows always uses pipes to connect stdout between processes
and for the terminal output. The previous implementation always assumed
that stdout connected to a pipe means that stdout is displayed on a
mintty terminal. However, this detection breaks when using pipes to
connect processes and for powershell which uses pipes when redirecting
to a file.

Now the pipe filename is queried and matched against the pattern used by
msys / cygwin when connected to the terminal. In all other cases assume
that a pipe is just a regular pipe.

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.

8a486eafed gs: Don't drop error when finishing upload
The error returned when finishing the upload of an object was dropped.
This could cause silent upload failures and thus data loss in certain
cases. When a MD5 hash for the uploaded blob is specified, a wrong
hash/damaged upload would return its error via the Close() whose error
was dropped.

cdd704920d azure: Pass data length to Azure libray
The azureAdapter was used directly without a pointer, but the Len()
method was only defined with a pointer receiver (which means Len() is
not present on a azureAdapter{}, only on a pointer to it).

c73316a111 backends: add sanity check for the uploaded file size
Bugs in the error handling while uploading a file to the backend could
cause incomplete files, e.g. https://github.com/golang/go/issues/42400
which could affect the local backend.

Proactively add sanity checks which will treat an upload as failed if
the reported upload size does not match the actual file size.

5c617859ab backup/scanner: Fix total size for overlapping targets
Before, the scanner would could files twice if they were included in the
list of backup targets twice, e.g. `restic backup foo foo/bar` would
could the file `foo/bar` twice.

This commit uses the tree structure from the archiver to run the
scanner, so both parts see the same files.

debc4a3a99 archiver: fix race condition during worker startup
When the tomb is created with a canceled context, then the workers
started via `t.Go` exist nearly immediately. Once for the first time all
started goroutines have been stopped, it is not allowed to issue further
calls to `t.Go`. This is a problem when the started goroutines exit
immediately, as for example the first goroutine might already have
stopped before starting the second one, which is not allowed as once the
first goroutines has stopped no goroutines were running.

To fix this race condition the startup and main task of the archiver now
also run within a `t.Go` function. This also allows unifying the error
handling as it is no longer necessary to distinguish between errors
returned by the workers or the saveTree processing. The tomb now just
returns the first error encountered, which should also be the most
descriptive one.

e483b63c40 retrybackend: Fail operations when context is already canceled
Depending on the used backend, operations started with a canceled
context may fail or not. For example the local backend still works in
large parts when called with a canceled context. Backends transfering
data via http don't work. It is also not possible to retry failed
operations in that state as the RetryBackend will abort with a 'context
canceled' error.

Ensure uniform behavior of all backends by checking for a canceled
context by checking for a canceled context as a first step in the
RetryBackend. This ensures uniform behavior across all backends, as
backends are always wrapped in a RetryBackend.

the error reported by the savers. However, in case of a canceled
background context that error is nil, causing restic to loose the
error and save a snapshot with a nil tree.

6c514adb8a ui/progress: Use mutex instead of atomic
The counter value needs to be aligned to 64 bit in memory for the
atomic functions to work on some platform (such as 32 bit ARM).

The atomic package says in its documentation:

> These functions require great care to be used correctly. Except for
> special, low-level applications, synchronization is better done with
> channels or the facilities of the sync package.

This commit replaces the atomic functions with a simple sync.Mutex, so
we don't have to care about alignment.

The canUpdateStatus check was simplified in #2608, but it accidentally flipped

restic probably runs in mintty/cygwin. In that case it's possible to
update the output status. In all other cases it isn't.

This commit inverts to condition again to offer the previous and correct
behavior.

eleith
a24e986b2b do not require gs bucket permissions to init repository
a gs service account may only have object permissions on an existing
bucket but no bucket create/get permissions.

these service accounts currently are blocked from initialization a
restic repository because restic can not determine if the bucket exists.

this PR updates the logic to assume the bucket exists when the bucket
attribute request results in a permissions denied error.

this way, restic can still initialize a repository if the service
account does have object permissions

b8c7543a55 check: Merge 'size could not be found' and 'not found in index' errors
By construction these two errors always show up in pairs: 'size could
not be found' is printed when the blob is not found in the repository
index. That blob is also part of the `blobs` array. Later on, check
iterates over that array and checks whether the blob is marked as
existing. Which cannot be the case as that mark is generated by
iterating over the repository index.

The merged warning no longer reports the blob index within a file. That
information could also be derived by printing the affected tree using
`cat` and searching for the blob.

e638b46a13 Embed context into ReaderAt
The io.Reader interface does not support contexts, such that it is
necessary to embed the context into the backendReaderAt struct. This has
the problem that a reader might suddenly stop working when it's
contained context is canceled. However, this is now problem here as the
reader instances never escape the calling function.

The list operation used by RemoveStaleLocks or RemoveAllLocks will

88c8e903d2 filter: Fix glob matching on absolute path marker on windows
A pattern part containing "/" is used to mark a path or a pattern as
absolute. However, on Windows the path separator is "\" such that glob
patterns like "?" could match the marker. The code now explicitly skips
the marker when the pattern does not represent an absolute path.

740758a5fa Optimize filter pattern matching
By replacing "**" with "", checking for this special path component can
be reduced to a length-zero check.

b79f18209f Upgrade github.com/cenkalti/backoff module
We now use v4 of the module. `backoff.WithMaxRetries` no longer repeats
an operation endlessly when a retry count of 0 is specified. This
required a few fixes for the tests.

bcc3bddcf4 filter: only check whether a child path could match when necessary
When checking excludes there is no need to test whether a child path
could also match the pattern, as it is by definition excluded.
Previously childMayMatch was calculated but then discarded. For simple
absolute paths this can account for half the time spent for checking
pattern matches.
