    • cmake: Sort source files for reproducible builds · b85eefb4
      We currently use `FILE(GLOB ...)` in most places to find source and
      header files. This is problematic in that the order of files returned
      depends on the operating system's directory iteration order and may thus
      not be deterministic. As a result, we link object files in unspecified
      order, which may cause the linker to emit different code across runs.
      
      Fix this issue by sorting all code used as input to the libgit2 library
      to improve the reliability of reproducible builds.

    • deps: fix implicit fallthrough warning in http-parser · cacbf998
      GCC 7 has introduced new warnings for implicit fallthrough in switch
      statements. Whenever there is no branch in a case block, GCC will watch
      out for some heuristics which indicate that the implicit fallthrough is
      intended, like a "fallthrough" comment. The third-party http-parser code
      manages to trick this heuristic in one case, even though there is a
      "FALLTHROUGH" comment. Fortunately, GCC has also added a strictness
      level to the -Wimplicit-fallthrough diagnostic, such that we can loosen
      this heuristic and make it more lax.
      
      Set -Wimplicit-fallthrough=1 in http-parser's CMake build instructions,
      which is the strictest level that gets rid of the warning. This level
      will treat any kind of comment as a "fallthrough" comment, which
      silences the warning.

    • cmake: fix static linking for bundled deps · 8c19969a
      Our bundled deps are being built as simple static libraries which are
      then linked into the libgit2 library via `TARGET_LINK_LIBRARIES`. While
      this works for a dynamically built libgit2 library, using this function
      to link two static libraries does not have the expected outcome of
      merging those static libraries into one big library. This leads to
      symbols of our bundled deps being undefined in the resulting libgit2
      archive.
      
      As we have bumped our minimum CMake version to 2.8.11, we can now easily
      make use of object libraries for our bundled dependencies. So build
      instructions are still self-contained inside of the dependency
      directories and the resulting object libraries can just be added to the
      LIBGIT2_OBJECTS list, which will cause them to be linked into the final
      resulting static library. This fixes the issue of undefined symbols.
