Michael Eischer	6b17a7110c	backup: Set O_NOATIME in the right place The archiver uses FS.OpenFile, where FS is an instance of the FS interface. This is different from fs.OpenFile, which uses the OpenFile method provided by the fs package.	2022-02-06 15:00:37 +01:00
greatroar	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.	2022-02-06 15:00:34 +01:00

Aneesh Agrawal	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.	2022-01-23 23:55:00 -05:00

Michael Eischer	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.	2021-11-13 21:57:30 +01:00

Michael Eischer	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.	2021-10-09 23:51:12 +02:00

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.	2021-04-11 20:02:09 +02:00
Michael Eischer	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.	2021-04-11 20:02:09 +02:00

Michael Eischer	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.	2020-12-30 17:31:22 +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.	2020-12-28 21:06:47 +01:00

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.	2020-12-06 19:02:42 +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 fixes: https://github.com/restic/restic/issues/3100	2020-11-18 06:14:11 -08:00

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.	2020-11-15 18:41:50 +01:00

Michael Eischer	8d0ba55ecd	backup: Fix possible deadlock of scanner goroutine When the backup is interrupted for some reason while the scanner is still active this could lead to a deadlock. Interruptions are triggered by canceling the context object used by both the backup progress UI and the scanner. It is possible that a context is canceled between the respective check in the scanner and it calling the `ReportTotal` method of the UI. The latter method sends a message to the UI goroutine. However, a canceled context will also stop that goroutine, which can cause the channel send operation to block indefinitely. This is resolved by adding a `closed` channel which is closed once the UI goroutine is stopped and serves as an escape hatch for reported UI updates. This change covers not just the ReportTotal method but all potentially affected methods of the progress UI implementation.	2020-09-30 23:13:10 +02:00

Michael Eischer	3cd927d180	rclone: Give rclone time to finish before closing stdin pipe Calling `Close()` on the rclone backend sometimes failed during test execution with 'signal: Broken pipe'. The stdio connection closed both the stdin and stdout file descriptors at the same moment, therefore giving rclone no chance to properly send any final http2 data frames. Now the stdin connection to rclone is closed first and will only be forcefully closed after a timeout. In case rclone exits before the timeout then the stdio connection will be closed normally.	2020-07-26 00:29:25 +02:00

Michael Eischer	8554332894	rclone: Close rclone side of stdio_conn pipes restic did not notice when the rclone subprocess exited unexpectedly. restic manually created pipes for stdin and stdout and used these for the connection to the rclone subprocess. The process creating a pipe gets file descriptors for the sender and receiver side of a pipe and passes them on to the subprocess. The expected behavior would be that reads or writes in the parent process fail / return once the child process dies as a pipe would now just have a reader or writer but not both. However, this never happened as restic kept the reader and writer file descriptors of the pipes. `cmd.StdinPipe` and `cmd.StdoutPipe` close the subprocess side of pipes once the child process was started and close the parent process side of pipes once wait has finished. We can't use these functions as we need access to the raw `os.File` so just replicate that behavior.	2020-07-26 00:29:25 +02:00

Michael Eischer	7a165f32a9	checker: Traverse trees in depth-first order Backups traverse the file tree in depth-first order and saves trees on the way back up. This results in tree packs filled in a way comparable to the reverse Polish notation. In order to check tree blobs in that order, the treeFilter would have to delay the forwarding of tree nodes until all children of it are processed which would complicate the implementation. Therefore do the next similar thing and traverse the tree in depth-first order, but process trees already on the way down. The tree blob ids are added in reverse order to the backlog, which is once again reverted when removing the ids from the back of the backlog.	2020-07-20 22:51:53 +02:00
Michael Eischer	36c69e3ca7	checker: Unify blobs, processed trees and referenced blobs map The blobRefs map and the processedTrees IDSet are merged to reduce the memory usage.

A third flag tracks whether a blob exists or not, which removes the need for the blobs IDSet.	2020-07-20 22:51:47 +02:00

Alexander Weiss	ce4a2f4ca6	save packIDs and duplicates separately A side remark to the definition of Index.blob: Another possibility would have been to use: blob map[restic.BlobHandle]indexEntry This would have led to the following sizes: key: 32 + 1 = 33 bytes value: 8 bytes indexEntry: 8 + 4 + 4 = 16 bytes each packID: 32 bytes To save N index entries, we would therefore have needed: N OF * (33 + 8) bytes + N * 16 + N * 32 bytes / BP = N * 82 bytes More precicely, using a pointer instead of a direct entry is the better memory choice if: OF * 8 bytes + entrysize < OF * entrysize <=> entrysize > 8 bytes * OF/(OF-1) Under the assumption of OF=1.5, this means using pointers would have been the better choice if sizeof(indexEntry) > 24 bytes.	2020-06-14 07:56:21 +02:00
