Here are some things on my to-do list, in no particular order:
|
||
|
|
|
||
|
|
* Automatically switch to a larger block size to reduce the overhead for files
|
||
|
|
that rarely change after being created (like >= 100MB video files :-)
|
||
|
|
|
||
|
|
* Implement the fsync(datasync) API method?
|
||
|
|
if datasync:
|
||
|
|
only flush user data (file contents)
|
||
|
|
else:
|
||
|
|
flush user & meta data (file contents & attributes)
|
||
|
|
|
||
|
|
* Implement rename() independently of link()/unlink() to improve performance?
|
||
|
|
|
||
|
|
* Implement `--verify-reads` option that recalculates hashes when reading to
|
||
|
|
check for data block corruption?
|
||
|
|
|
||
|
|
* `report_disk_usage()` has become way too expensive for regular status
|
||
|
|
reports because it takes more than a minute on a 7.0 GB database. The only
|
||
|
|
way it might work was if the statistics are only retrieved from the database
|
||
|
|
once and from then on kept up to date inside Python, but that seems like an
|
||
|
|
awful lot of work. For now I've removed the call to `report_disk_usage()`
|
||
|
|
from `print_stats()` and added a `--print-stats` command-line option that
|
||
|
|
reports the disk usage and then exits.
|
||
|
|
|
||
|
|
* Tag databases with a version number and implement automatic upgrades because
|
||
|
|
I've grown tired of upgrading my database by hand :-)
|
||
|
|
|
||
|
|
* Change the project name because `DedupFS` is already used by at least two
|
||
|
|
other projects? One is a distributed file system which shouldn't cause too
|
||
|
|
much confusion, but the other is a deduplicating file system as well :-\
|
||
|
|
|
||
|
|
* Support directory hard links without upsetting FUSE and add a command-line
|
||
|
|
option that instructs `dedupfs.py` to search for identical subdirectories
|
||
|
|
and replace them with directory hard links.
|
||
|
|
|
||
|
|
* Support files that don't fit in RAM (virtual machine disk images…)
