- refactor some code:
- code handling the file cache is now in fuse/filecache.c
- base36 and base16 encoding and decoding moved to utils/hash.c
- mfshell: add "updates" command calling device/get_updates
- add container class to store patch information as mfapi/patch.c
- apicalls: store more info retrieved by file/get_info
- apicalls: add device/get_updates
- apicalls: add device/get_patch
- don't use folder/get_content but rely on parent information
- add many more debugging information and sanity checks
- ignore trash
- correctly update local device revision using device_response
- remove "visited" member and change housekeeping function to check for
consistency of parents and children (and retrieve fix from remote if
necessary)
- print key and parent key in the debugging function
- check for remote updates on every fs function
- introduce global defines for key and filename length
- add parent member, getters and setters to file.h
- utils is the low level library used by the others
- mfapi uses utils and implements the api and some wrappers
- mfshell uses mfapi and utils to provide a shell
