* Created AsyncTaskService to build async UI operations which always log
uncaught exceptions
* Changed all executor service invocations in the UI to invocations of
AsyncTaskService
* Improved error handling in some other places, especially
try-with-resources
* Unlocking read/write locks in NioFile when opening of a channel fails
* CryptoWritableFile no longer writes header with zero size if file is
opened for writing
* Refactored FileContentDecryptor: Using Supplier<Mac> instead of
ThreadLocal<Mac>
* Fixed InMemoryWritableFile: No longer open after moveTo
This caused an illegal state where two different directories share the same directory id, making further file operations on these directories virtually impossible.
* Removed from SharedFileChannel and Test
* Refactored Copier#copy(File,File) to sequence of truncated, followed
by looping read and write till EOF
* Changed tests accordingly
* Implemented CryptoWritableFile#truncate to make things work
* Does always copy the full contents
* Does always overwrite all contents in the target file
* Added file invariant test to test write after read returns written
bytes
- Using WeakValuedCache in all filesystem layers to prevent "twin" instances of the same folder
- Merge branch 'layered-io' of https://github.com/cryptomator/cryptomator into layered-io
* Getter and setter for files and folders
* A way to determine if a file system supports creation dates
* WebDav compliant implementation in jackrabbit-adapter
* Tests
* Removed Readable- and WritableBytes
** Replaced with Readable-/WritableByteChannel
** Methods now integrated in Readable- and WritableFile
** Replaced positioned read/write by method to set the position
* Partial implementation of nio filesystem
* Removed timeouts from openReadable and openWritable
* Added convenience methods for copying
* Added utility to support deadlock safe opening of multiple files
