Erica Marigold	ecace02e7f	feat: add ZipEntry:unixMode() to get unix mode values as octals ... Updates tests, and makes the `tour` example display the perms instead of the raw external attributes.	2025-01-09 16:16:38 +00:00
Erica Marigold	6c1f517b75	feat: add compressedSize and :compressionEfficiency() ... Adds a field for getting the compressed size of a zip entry and a method to get the compression efficiency as a percentage.	2025-01-09 15:11:18 +00:00
Erica Marigold	d93f1f2383	feat: add path safety and sanitization methods to ZipEntry ... * Added `ZipEntry:getSafePath` which returns the path of the entry if it was safe, or nil * Added `ZipEntry:sanitizePath` which converts a potentially unsafe path to a safe one, although it can change the meaning of the paths * Updated path utility with functions `isSafe` and `sanitize` * Path utility now always uses `/` as a path separator, converting `\\` to `/` when needed * Included tests for path utility	2025-01-09 07:25:59 +00:00

Erica Marigold	ccc7228278	fix: avoid duplicate directory entries with trailing slash ... Fixed a bug in the directory tree builder where for directories there would be two entries, where one would have a trailing slash, and the other wouldn't. The directory without the trailing slash would get linked to its children in the entries lookup table, while the one with the trailing slash would exist as a "ghost directory" with no children. The fix involved sorting the entries to first handle directories, and linking to the existing parent directory entries for children.	2024-12-31 12:46:45 +00:00
