See src/README for the README that ships with snappy.

Mozilla does not modify the actual snappy source with the exception of the

'snappy-stubs-public.h' header and one small patch to resolve implicit

constructor warnings. We have replaced its build system with our own.

Snappy comes from:

  https://github.com/google/snappy

We are currently using revision: 1.2.0

To upgrade to a newer version:

  1. Check out the new code using git.

  2. Update 'snappy-stubs-public.h' in this directory with any changes that were

     made to 'snappy-stubs-public.h.in' in the new source. Note that we don't

     bother trying to detect the availability of sys/uio.h and unconditionally

     define the iovec type instead for all platforms.

  3. Copy the major/minor/patch versions from 'CMakeLists.txt' into

     'snappy-stubs-public.h'.

  4. Copy all source files from the new version into the src subdirectory. The

     following are not needed:

       - 'CMakeLists.txt', 'snappy_benchmark.cc', 'snappy_test_data.cc',

         'snappy_test_data.h', and 'snappy_test_tool.cc' files

       - 'cmake' subdirectory

       - 'docs' subdirectory

       - 'testdata' subdirectory

       - 'third_party' subdirectory

  5. Update the revision stamp in this file.

  6. Apply 01-explicit.patch.
