## [Unreleased]
### New
- Additional tests to increase code coverage ([!141](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/141)).
- GKFS_ENABLE_UNUSED_FUNCTIONS added to disable code to increase code coverage.
### Changed
- Support parallelism for path resolution tests ([!145](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/145)).

- Support parallelism for symlink tests ([!147](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/147)).
### Removed
### Fixed
- Using `unlink` now fails if it is a directory unless the `AT_REMOVEDIR` flag is used (POSIX compliance) ([!139](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/139)).
- Support glibc-2.34 or newer with syscall_intercept [!146](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/146)).
- Additional `#ifdef` to remove unused code ([!141](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/141))
- An CMake issue in `path_util` that caused the compilation to fail was fixed ([!115](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/115)).

they are dispatched to the shared backend parallel file system.
- The `fsync()` system call is now fully supported.
### Improved
- Argobots tasks in the daemon are now wrapped in a dedicated class,
effectively removing the dependency. This lays ground work for future
non-Argobots I/O implementations.
- The `readdir()` implementation has been refactored and improved.
- Improvements on how to the installation scripts manage dependencies.
### Fixed
- The server sometimes crashed due to uncaught system errors in the storage
backend. This has now been fixed.
- Fixed a bug that broke `ls` on some architectures.

### Changed

## [0.6.2] - 2019-10-07
### Added
- Paths inside kernel pseudo filesystems (`/sys`, `/proc`) are forwarded directly to the kernel and internal path resolution will be skipped. Be aware that also paths like `/sys/../tmp/gkfs_mountpoint/asd` will be forwarded to the kernel
- Added new Cmake flag `CREATE_CHECK_PARENTS` to controls if the existance of the parent node needs to be checked during the creation of a child node.

- Updated Margo, Mercury and Libfabric dependencies
### Fixed
- mk_node RPC wasn't propagating errors correctly from daemons
- README has been improoved and got some minor fixes
- fix wrong path in log call for mk_symlink function
## [0.6.1] - 2019-09-17
### Added
- Added new Cmake flag `LOG_SYSCALLS` to enable/disable syscall logging.
- Intercept the 64 bit version of `getdents`.
- Added debian-based docker image.
### Changed
- Disable syscalls logging by default
- Update Mercury, RocksDB and Libfabric dependencies
### Fixed
- Fix read at the end of file.
- Don't create log file when using `--version`/`--help` cli flags.

- Missing definition of `loff_t` on new version of GCC.
## [0.6.0] - 2019-07-26
### Added
- Add compile time option to disable shared memory communication `-DUSE_SHM:BOOL=OFF`
### Changed
- Deamons does not store anymore information about the others deamons.
- Improoved error handling on deamon initialization
- Decreased RPC timeout 3min -> 3sec
- Update 3rd party dependencies
### Removed
- PID file is not used anymore, we use only the new `hosts file` for out of bound communication
- Dropped CCI plugin support
- Dropped hostname-suffix cli option
- Dropped port cli option (use `--listen` instead)
- It is not needed anymore to pass hosts information to deamons, thus the `--hosts` cli have been removed
### Fixed
