Michael Eischer d0ca8fb0b8 backend: test that a canceled context prevents RetryBackend operations 2020-12-28 21:06:47 +01:00
Michael Eischer 08b7f2b58d archiver: test that context canceled error is not dropped 2020-12-28 21:06:47 +01:00
Michael Eischer 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.

Michael Eischer fc60b560ba archiver: Let saveTree report a canceled context as an error
If the context was canceled then saveTree might receive a treeID or not
depending on the timing. This could cause saveTree to incorrectly return
a nil treeID as valid. Fix this always returning an error when the
context was canceled in the meantime.

Michael Eischer 736e964317 archiver: Don't loose error if background context is canceled
A canceled background context lets the blob/tree/fileSavers exit
without reporting an error. The error handling previously replaced
a 'context canceled' error received by the main backup method with
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.

Alexander Neumann 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.

Michael Eischer b48f579530 termstatus: Fix canUpdateStatus detection for redirected output
The canUpdateStatus check was simplified in #2608, but it accidentally flipped
the condition. The correct check is as follows: If the output is a pipe then
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.

On shutdown the backup commands waits for the terminal output goroutine
to stop. However while running in the background the goroutine ignored
the canceled context.

Michael Eischer d05c88a5d6 fuse: Properly set uid/gid for directories
In #2584 this was changed to use the uid/gid of the root node. This
would be okay for the top-level directory of a snapshot, however, this
change also applied to normal directories within a snapshot. This
change reverts the problematic part and adds a test that directory
attributes are represented correctly.

Merge pull request #3107 from eleith/do-not-require-bucket-permissions-for-init
do not require gs bucket permissions to init repository
2020-11-18 16:53:45 +01:00
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

Michael Eischer 1f43cac12d check: Only track data blobs when unused blobs should be reported
This improves the memory usage of check a lot as it now only has to

Michael Eischer 3500f9490c check: Simplify blob status tracking
UnusedBlobs now directly reads the list of existing blobs from the
repository index. This removes the need for the blobStatusExists flag,
which in turn allows converting the blobRefs map into a BlobSet.

Michael Eischer 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.
