Draft
Conversation
* Use more consistent typing on the C++ side: paths are fs::path, strings are std::string * Implement FUSE open/release and avoid opening/closing the file for each read call (as well as the expensive get_real_path!) * Implement FUS opendir/releasedir * Reduce the number of directories that need to be lstat-ed when using readdir by remembering the real path of the root.

Also: Thanks for this tool! I was a bit concerned how to unfurl my backup (old long-gone computer!) |

There was a problem hiding this comment.
Reading through this, original code was better I think and more explicit:
Suggested change
| int fd = open(real_path.c_str(), fi->flags); | |
| int fd = open(real_path.c_str(), O_RDONLY); |

I needed to use tmfs to extract about 150GiB of data from a time machine backup. While that worked, it was unbearably slow. Looking at the code there were a bunch of "low-hanging fruit".
I'll leave this as a draft for discussion, probably it would be good to clean this up a bit more and split the pure refactorings (such as using fs::path/std::string and the file renamings) from the more functional parts.
