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.

4b0fcaed45 unlock: use proper context for locks cleanup 
The list operation used by RemoveStaleLocks or RemoveAllLocks will
already be canceled by the passed in context. Therefore we can also just
cancel the remove operation as the unlock command won't process all lock
files anyways.

a449450021 init: pass proper context to master key generation 
This is no change in behavior as a canceled context did later on cause
the config file creation to fail. Therefore this change just lets the
repository initialization fail a bit earlier.

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.

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.

673dda77c0 Less repetitive error messages in internal/cache 
Many instances of errors.Wrap in this package would produce messages
like "Open: open <filename>: no such file or directory"; those now omit
the first "Open:" (or "Stat:", or "MkdirAll"). The function readVersion
now appends its own name to the error message, rather than the function
that failed, to make it easier to spot. Other function names (e.g.,
Load) are already added further up in the call chain.

os.FileInfo. Checking first is more obvious and requires less code.

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.

transport to try to reestablish a new connection. As previously this never
should have happened, the connection called panic in that case. This
panic is now replaced with a simple error message, as it no longer
indicates an internal problem.

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.

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.

In the Google Cloud Storage backend, support specifying access tokens
directly, as an alternative to a credentials file. This is useful when
restic is used non-interactively by some other program that is already
authenticated and eliminates the need to store long lived credentials.

The access token is specified in the GOOGLE_ACCESS_TOKEN environment
variable and takes precedence over GOOGLE_APPLICATION_CREDENTIALS.

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.

36c69e3ca7 checker: Unify blobs, processed trees and referenced blobs map 
The blobRefs map and the processedTrees IDSet are merged to reduce the
memory usage. The blobRefs map now uses separate flags to track blob
usage as data or tree blob. This prevents skipping of trees whose
content is identical to an already processed data blob. A third flag
tracks whether a blob exists or not, which removes the need for the
blobs IDSet.

exactly once.

createRandomIndex was using the global RNG, which locks on every call
It was also using twice as many random numbers as necessary and doing
a float division in every iteration of the inner loop.

BenchmarkDecodeIndex was using too short an input, especially for a
parallel version. (It may now be using one that is a bit large.)

1361341c58 don't save duplicate packIDs when using internal/repository/Index.Store 2020-06-14 07:56:24 +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.

- The SaveBlob method now checks for duplicates.
- Moves handling of pending blobs to MasterIndex.
  -> also cleans up pending index entries when they are saved in the index
  -> when using SaveBlob no need to care about index any longer
- Always check for full index and save it when storing packs.
  -> removes the need of an index uploader
  -> also removes the verbose "uploaded intermediate index" messages
- The Flush method now also saves the index
- Fix race condition when checking and saving full/non-finalized indexes

bdf7ba20cb archiver: Fix race condition triggered by TestArchiverAbortEarlyOnError 
The Save methods of the BlobSaver, FileSaver and TreeSaver return early
on when the archiver is stopped due to an error. For that they select on
both the tomb.Dying() and context.Done() channels, which can lead to a
race condition when the tomb is killed due to an error: The tomb first
closes its Dying channel before canceling all child contexts.
Archiver.SaveDir only aborts its execution once the context was
canceled. When the tomb killing is paused between closing its Dying
channel and canceling the child contexts, this lets the
FileSaver/TreeSaver.Save methods return immediately, however, ScanDir
still reads further files causing the test case to fail.

As a killed tomb always cancels all child contexts and as the Savers
always use a context bound to the tomb, it is sufficient to just use
context.Done() as escape hatch in the Save functions. This fixes the
mismatch between SaveDir and Save.

Adjust the tests to use contexts bound to the tomb for all interactions
with the Savers.

90fc639a67 Allow specifying user and host when adding keys 
The username and hostname for new keys can be specified with the new
--user and --host flags, respectively. The flags are used only by the
`key add` command and are otherwise ignored.

This allows adding keys with for a desired user and host without having
to run restic as that particular user on that particular host, making
automated key management easier.

a23e9c86ba Remove closing logic from Packer.Finalize 
The method only ever receives *hashing.Writers, which don't implement
io.Closer. These come from packerManager.findPacker and have their
actual writers closed in Repository.savePacker. Moving the closing logic
to hashing.Writer results in "file already closed" errors.

b46cc6d57e repository: Don't sort one element pack lists 
When loading a blob, restic first looks up pack files containing the
blob. To avoid unnecessary work an already cached pack file is preferred.
However, if there is only a single pack file to choose from (which is
the normal case) sorting the one-element list won't change anything.
Therefore avoid the unnecessary cache check in that case.

2828a9c2b0 Fix running tests on a SELinux enabled system 
Archivers TestMetadataChanged incorrectly clears the Extended Attributes
from the expected metadata of the temporary file. This is incorrect as on
SELinux enabled filesystem, as the kernel will automaticly add a SElinux
label. However, since ExtendedAttributes{} != ExtendedAttributes{nil} we
still need to clear them if there are no attributes found.

e1f722d266 archiver: Fix flaky TestArchiverAbortEarlyOnError 
Each of the random test files was split into the same five blobs. The
test fails once the fifth blob is passed on to `SaveBlob`. That is for
certain interleavings of goroutine execution it would be possible for
the test to trigger the testErr just after storing the first file.

The fixed test uses a different file content for each of the nine files
and fails after writing the fourth blob. The file content is also small
enough to ensure that for each file only a single blob is saved. This
guarantees that the test cannot fail before reading the first four
files. FileReadConcurrency = 2 allows up to two files queued for
processing. Therefore the test can at most open the sixth file before it
has to save the fourth file / blob which triggers the testErr.

da48b925ff remove unnecessary error return 
I was running "golangci-lint" and found this two warnings

internal/checker/checker.go:135:18: (*Checker).LoadIndex$3 - result 0 (error) is always nil (unparam)
        final := func() error {
                        ^
internal/repository/repository.go:457:18: (*Repository).LoadIndex$3 - result 0 (error) is always nil (unparam)
        final := func() error {
                        ^

It turns out that these functions are used only in "RunWorkers(...)",
which is used only two times in whole project right after this "final"
functions.
And because these "final" functions always return "nil", I've
descided, that it would be better to remove requriments for "final" func
to return error to avoid magick "return nil" at their end.
