a2d4209322 Don't recurse in local backend's List if not required
Due to the return if !isFile, the IsDir branch in List was never taken
and subdirectories were traversed recursively.

Also replaced isFile by an IsRegular check, which has been equivalent
since Go 1.12 (golang/go@a2a3dd00c9).

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 marker when the pattern does not represent an absolute path.

0acc3c5923 filter: special case patterns without globbing characters
In case a part of a path is a simple string, we can just check for
equality without complex parsing in filepath.Match.

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.

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.

tampered with the backup or indicates hardware problems on the client.

c81b122374 rclone: Don't panic after unexpected subprocess exit
As the connection to the rclone child process is now closed after an
unexpected subprocess exit, later requests will cause the http2
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.

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.

255ba83c4b Parallel index benchmarks + benchmark optimizations
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.)

Results on linux/amd64, -benchtime=3s -count=20:

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.

91906911b0 Fix non-intuitive repository behavior
- 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

649cbec6c5 Simplify build tags for restic mount
This command can only be built on Darwin, FreeBSD and Linux
(and if we upgrade bazil.org/fuse, only FreeBSD and Linux:
https://github.com/bazil/fuse/issues/224).

Listing the few supported operating systems explicitly here makes
porting restic to new platforms easier.

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.

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.

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.

939f3e972c node: Make sure year of all timestamps is valid
Sometimes restic gets bogus timestamps which cannot be converted to
JSON, because the stdlib JSON encoder returns an error if the year is
not within [0, 9999]. We now make sure that we at least record _some_
timestamp and cap the year either to 0000 or 9999. Before, restic would
refuse to save the file at all, so this improves the status quo.

This fixes #2174 and #1173

This commit changes the signatures for repository.LoadAndDecrypt and

buffer is enlarged as needed, and returned back to the caller for
further use.

In later commits, this allows reducing allocations by reusing a buffer
for multiple calls, e.g. in a worker function.

3c112d9cae s3: Add config option to set storage class
The `s3.storage-class` option can be passed to restic (using `-o`) to
specify the storage class to be used for S3 objects created by restic.

The storage class is passed as-is to S3, so it needs to be understood by
the API. On AWS, it can be one of `STANDARD`, `STANDARD_IA`,
`ONEZONE_IA`, `INTELLIGENT_TIERING` and `REDUCED_REDUNDANCY`. If
unspecified, the default storage class is used (`STANDARD` on AWS).

You can mix storage classes in the same bucket, and the setting isn't
stored in the restic repository, so be sure to specify it with each
command that writes to S3.

c4fbf2c779 Return error when reading zero byte from stdin
This commit changes the internal file system implementation for reading
data from stdin, it now returns an error when no bytes could be read. I
think it's worth failing in this case, the user instructed restic to
read some data from stdin, and no data was read at all. Maybe it was in
a pipe and some earlier stage failed.

See #2135 for a short discussion.
2019-01-06 14:52:20 +01:00
Alexander Neumann
7c084014fa Use processed bytes for summary
When restic reads the backup from stdin, the number of bytes processed
was always displayed as zero. The reason is that the UI for the archive
uses the total bytes as returned by the scanner, which is zero for
stdin. So instead we keep track of the real number of bytes processed
and print that at the end.

e42d2d1da8 restore: suppress lchown errors when not running as root
Like "cp -a" and "rsync -a" do, only report lchown errors if we run
as root.

Like cp from GNU coreutils does, we check Geteuid() to determine if
we are running as root
( http://git.savannah.gnu.org/cgit/coreutils.git/tree/src/copy.c#n3012 ).

On Windows, lchown errors are always reported.

1140950d7b scanner: Use context only for cancellation
When the scanner is slower than the actual backup, the tomb cancels the
context passed to Scan(), which then returns ctx.Err(). In the end, the
main function prints an error message that is not helpful ("Context
cancelled") and exits with an error code although no error occurred.

The code now ignores the error in the context and just uses it for
cancellation. The scanner is not supposed to return an error anyway.

Closes #1978

6d53e767d5 cache: Print message when new cache is created
Sometimes, users run restic without retaining the local cache
directories. This was reported several times in the past.

Restic will now print a message whenever a new cache directory is
created from scratch (i.e. it did not exist before), so users have a
chance to recognize when the cache is not kept between different runs of
restic.

6e1a3987b7 Add 'self-update' command
This commit adds a command called `self-update` which downloads the
latest released version of restic from GitHub and replacing the current
binary with it. It does not rely on any external program (so it'll work
everywhere), but still verifies the GPG signature using the embedded GPG
public key.

By default, the `self-update` command is hidden behind the `selfupdate`
built tag, which is only set when restic is built using `build.go`. The
reason for this is that downstream distributions will then not include
the command by default, so users are encouraged to use the
platform-specific distribution mechanism.

b07bb3d8c3 Reject files excluded by name before calling lstat to improve scan speed
Adds a SelectByName method to the archive and scanner which only require
the filename as input, and can thus be run before calling lstat on the
file. Can speed up scanning significantly if a lot of filename excludes
are used.

44924ba043 restorer: Fix traverseTree
traverseTree() was meant to call enterDir() whenever a directory is
selected for restore, either explicitly or implicitly (=contains a file
which is to be restored). After restoring a file, leaveDir() is called
in reverse order for all intermediate directories so that the metadata
can be restored.

When a directory is selected implicitly, the metadata for it is
restored. This is different from the previous restorer behavior, which
created implicitly selected intermediate directories with permissions
0700 (only user can read/write it).

This commit changes the behavior back to the old one. Only a directory
is explicitly selected for restore, enterDir()/leaveDir() are called for
it. Otherwise, only visitNode() is called, so visitNode() needs to make
sure the parent directory exists. If the directory is explicitly
included, leaveDir() will then restore the metadata correctly.

When we decide to change the behavior (restore metadata for all
intermediate directories, even if selected implicitly), we should do
that in the selection functions, not here.

This finally resolves #1870

fc5439a37a cache: Ensure failed downloads are retried
This fixes #1833, which consists of two different bugs:

 * The `defer` in `cacheFile()` may remove a channel from the
   `inProgress` map although it is not responsible for downloading the
   file

 * If the download fails, goroutines waiting for the file to be cached
   assumed that the file was there, there was no way to signal the
   error.
