At least in neovim, `│vi:` is not recognized as a modeline because it
has no preceding whitespace. After fixing this, opening a file yields
an error because `net` is not an option. (`noet`, however, is.)
This change gets GNU grep working. What caused it to not work, is it
wouldn't write to an output file descriptor when its dev/ino equaled
/dev/null's. So now we invent special dev/ino values for these files
This reverts commit b01282e23e. Some tests
are broken. It's not clear how it'll impact metal yet. Let's revisit the
memory optimization benefits of this change again sometime soon.
This reduces the virtual memory usage of Emacs for me by 30%. We now
have a simpler implementation that uses read(), rather mmap()ing the
whole executable.
readdir() will now always yield an inode that's consistent with stat()
on ZipOS and Windows in general. More APIs have been updated to return
the appropriate error code when inappropriately trying to do ops, like
sockets, with a zip file descriptor. The path normalization algorithms
are now fully fleshed out. Some socket APIs have been fixed so they'll
raise EBADF vs. ENOTSOCK appropriately. Lastly seekdir() will now work
properly on NetBSD and FreeBSD (not sure why anyone would even use it)
