This extends the FUSE mount code to work on macOS with libfuse3, which uses different struct types (fuse_darwin_attr instead of stat) and callback signatures. The changes keep existing support for Linux libfuse3 and older libfuse/libosxfuse intact by using conditional compilation.
Implement tolerant mode that allows the filesystem to continue operating when encountering certain errors. When enabled, the mount_fuse tool will skip problematic directory entries instead of failing the entire operation. This adds: - libfsapfs_volume_set_tolerant_mode() function - Tolerant mode flag in libfsapfs_volume_t - Propagation to file system B-tree - Error handling in mount_fuse_readdir() to skip errors in tolerant mode

Thanks for the suggested changes. macfuse related changes in https://github.com/libyal/libfsapfs/actions/runs/27749993681/job/82097769144 I'll keep this open for now to assess the error tolerant mode at a later time |

this implements a tolerant mode feature that allows the filesystem to continue operating even when encountering certain recoverable errors. when enabled, the mount point remains functional by skipping problematic directory entries rather than failing completely. this is particularly useful when dealing with corrupted or partially damaged APFS images where some metadata may be unreadable. the implementation adds a new libfsapfs_volume_set_tolerant_mode() function, introduces a tolerant_mode flag in the volume structure, ensures propagation of this setting to the file system Btree, and modifies the fuse readdir callback to handle errors gracefully based on the mode. it also extends macOS compatibility by adding support for libfuse3 on macOS (tested on 26.3).
* i tested the tolerant mode with -R flag in a directory known to be corrupted.
