• 关于minizip-ng无法解压unix下压缩的带有文件夹的zip文件

    1. 什么是minizip-ng

    minizip-ng是继zlib的contribute下的minizip重构而来的。具体详情参考

    2. minizip-ng库提取unix下zip压缩的目录失败

    注意:minizip压缩目录时需要加上-i选项，否则压缩的文件直接时平铺的，没有任何目录在里面 

    1. minizip-ng/minizip-ng-2.3.9/build/test.dir$ tree 
    2. .
    3. ├── a.txt
    4. └── locker

    7. 1 directory, 2 files
    8. minizip-ng/minizip-ng-2.3.9/build/test.dir$ ../minizip ../test.zip ./*

    2.3 分析原因

    minizip获取压缩文件条目时，条目属性和os的文件类型没有匹配好而导致的.

     后面使用新的minizip板本验证，此问题已经得到解决了.目前在minizip-ng-2.10.6.tar.gz和minizip-ng-3.0.0.tar.gz以及minizip-ng-3.0.6.tar.gz验证都是ok的
