kitone 6099f81692 Fix #1212 restore code produces inconsistent timestamps/permissions. 
Keep track of restored child status so parent and root directory not selected by filter will also restore metadata when traversing tree.

Michael Eischer 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.

Michael Eischer 2964d2ad15 Skip unlocking for nil locks 
Now that lockRepo receives a context, it is possible that it is canceled
before a lock was created. Thus `unlockRepo` must be able to handle this
case.

Michael Eischer 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.

Michael Eischer 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.

Michael Eischer 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.
 2020-10-09 16:11:05 +02:00
greatroar 740758a5fa Optimize filter pattern matching 
By replacing "**" with "", checking for this special path component can
be reduced to a length-zero check.

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.

Michael Eischer 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.

Michael Eischer 40ee17167e local: Ignore permission errors on chmod call in Save/Remove operation 
The file is already created with the proper permissions, thus the chmod
call is not critical. However, some file systems have don't allow
modifications of the file permissions. Similarly the chmod call in the Remove
operation should not prevent it from working.
