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.
