v2.1.6

v2.1.4

Compare Source

🐛 Bug Fixes

• We now keep searching for a real CDE header after read an invalid one from the file comment
• Always search for data start when opening an archive for append, and reject the header if data appears to start after central directory
• deep_copy_file no longer allows overwriting an existing file, to match the behavior of shallow_copy_file
• File start position was wrong when extra data was present
• Abort file if central extra data is too large
• Overflow panic when central directory extra data is too large

• path_to_string now properly handles the case of an empty path
• Implement Debug for ZipWriter even when it's not implemented for the inner writer's type
