  • Support legacy ZIP compression methods (for decompression at least)

    From Rob Swindell@1:103/705 to GitLab issue in main/sbbs on Tuesday, May 06, 2025 17:20:22
    open https://gitlab.synchro.net/main/sbbs/-/issues/928

    libarchive and zlib don't support legacy (pre-DEFLATED) ZIP compression methods. But it can be done:

    https://www.hanshq.net/zip2.html
    https://github.com/jsummers/oldunzip/

    This would allow the extraction and viewing or subsequent download of archived files from legacy ZIP files.

    Whether this is done as a patch to zlib or libarchive or something internal to sbbs, it seems totally doable.

    It looks like the libarchive team would be willing to consider implementing implode/explode if someone were to submit it so maybe that's the place for it?
