New ZipArchive release

The following steps should be taken by project maintainers when they create a new release.

  1. Create a new release and tag for the release.

    • Tags should be in the form of Major.Minor.Revision

    (Xcode SPM tools do not pick up vMajor.Minor.Revision used in older releases. After 2.4.2 please do not include the v in the tag name)

    • Release names should be more human readable: Version Major.Minor.Revision

  2. Update the podspec and test it

    • pod lib lint SSZipArchive.podspec

  3. Push the pod to the trunk

    • pod trunk push SSZipArchive.podspec

Note: We are no longer releasing a Carthage release as of 2.2.3. Developers are encouraged to build one themselves.

Minizip-ng (formally minizip) update

The following steps should be taken by project maintainers when they update minizip files.

  1. Source is at https://github.com/zlib-ng/minizip-ng.
  2. Have cmake: brew install cmake
  3. Run cmake on minizip repo with our desired configuration: cmake . -DMZ_BZIP2=OFF -DMZ_LZMA=OFF -DMZ_ZLIB=ON -DMZ_LIBCOMP=OFF
  4. Look at the file ./CMakeFiles/minizip.dir/DependInfo.cmake it will give you the following information:
  • The list of C files that we need to include.
  1. Look at the file ./CMakeFiles/minizip.dir/flags.make it will give you the following information:
  • The list of compiler flags that we need to include (as of minizip 3.0.5 we have to include either zlib-ng OR ZLIB_COMPAT)

Note: These should not be changed unless you have issues compiling or we bump the min os versions.

HAVE_INTTYPES_H HAVE_PKCRYPT HAVE_STDINT_H HAVE_WZAES HAVE_ZLIB ZLIB_COMPAT

With the exception of the last two: "MZ_ZIP_SIGNING" "_POSIX_C_SOURCE=200112L"

  1. Set those flags in SSZipArchive.podspec (for CocoaPods) and in ZipArchive.xcodeproj (for Carthage)

  2. Replace the .h and .c files with the latest ones, except for mz_compat.h, which is customized to expose some struct in SSZipCommon.h and to provide support for optional aes.

Note: we can also use cmake -G Xcode . -DMZ_BZIP2=OFF -DMZ_LZMA=OFF -DMZ_ZLIB=ON -DMZ_LIBCOMP=OFF to get the list of files to include in an xcodeproj of its own, from where we can remove unneeded zip.h and unzip.h.
