v2.7

What's new?

• LFS_FUSE_VERSION and a GitHub Action for tests and releases (such as this) (#52).

  As noted by @elpiel, CI on littlefs-fuse has been broken since moving from Travis CI -> GitHub Actions (the org moved but not this repo). Fortunately littlefs-fuse is redundantly tested in littlefs's CI, so the main issue is this meant releases weren't being generated.

  This PR fixes that and also adds a littlefs-fuse specific version number. The current version matches littlefs, but will not necessarily be in-sync moving forwards. This makes it possible to create minor releases for littlefs-fuse without needing a minor release in the core repo, though may make the number of different version strings flying around a bit confusing.

  Since littlefs-fuse doesn't really have a header file, this version is mainly used for the CI, though is included in the CLI version info to help debugging:

  $ ./lfs --version
  littlefs-fuse version: v2.6                   
  littlefs version: v2.6                        
  littlefs disk version: v2.1                   
  FUSE library version: 2.9.9                   
  fusermount3 version: 3.10.5                   
  using FUSE kernel interface version 7.19      

• Adopted on-disk minor version features leveraging the new APIs introduced in littlefs v2.7 (#53):

  • Integrated lfs_fs_stat into statvfs, so statvfs.namemax reports the on-disk name_max correctly.

  • Added ./lfs --stat, which allows you to access littlefs-specific info without needing to mount the filesystem. Currently this includes:

    • on-disk version
    • block_size (from ioctl)
    • block_count (from ioctl)
    • block usage as both used, free, and percentage, for convenience
    • on-disk name_max
    • on-disk file_max
    • on-disk attr_max

    This may be extended in the future

    Example output:

    $ ./lfs --stat /dev/loop9
    disk_version: lfs2.1
    block_size: 512
    block_count: 131072
      used: 2/131072 (0.0%)
      free: 131070/131072 (100.0%)
    name_max: 255
    file_max: 2147483647
    attr_max: 1022

  • Added support for writing previous minor versions of littlefs via the --disk_version (-d) flag. Note because of limitations in FUSE's argument parser, this requires an equal sign:

    $ ./lfs -d=lfs2.0 --format /dev/loop9
    $ ./lfs --stat /dev/loop9
    disk_version: lfs2.0
    ...

• Fixed some bugs thanks to user reports:

  • Fixed incorrect block_count when block_size is >512 bytes due to confusion around BLKGETSIZE, thanks to @taorye (#46).
  • Fixed incorrect handling of partial reads/writes, thanks to @lucckb (#54).
