- create_zip from a subdirectory wrote entry names with a leading
'/', so the mounted archive looked empty
- memory_ostream did not support tellp(), so create_zip into a memory
device wrote invalid offsets (-1) to the archive
- ZipFileDevice added missing parent directories for the first entry
only
- ZipFileDevice::exists returned false for the archive root
- MemoryDevice::mkdirs recreated existing directories, dropping their
content (mkdir("a/b") cleared "a"); overwriting a file duplicated its
name in the directory listing
Added dev/tests/zip_files.lua: builds archives with file.create_zip
from memory device root, subdirectories and the real filesystem,
mounts them and checks reading, listing and read-only access.
memory_filesystem.lua got checks for the MemoryDevice issues.
Closes#544
