      Prepare to unit-test C stuff · cd5646af
      Kirill Smelkov authored
      We'll be testing C code in a similiar-to-python way - keep test_*.c
      files nearby and compile/executing them as needed.
      
      Tests are run several times in several ways - as plainly compiled and
      also with additional error checkers:
      
       - AddressSanitizer
       - ThreadSanitizer
       - and similiar checkers from Valgrind

      lib/mem: Python utilities to zero, set & copy memory · 699b1375
      Kirill Smelkov authored
      Like C bzero / memset & memcopy - but work on python buffers. We
      leverage NumPy for doing actual work, and this way NumPy becomes a
      depenency.
      
      Having NumPy as a dependency is ok - we'll for sure need it later as we
      are trying to build out-of-core ndarrays.

      lib/utils: Small C utilities we'll use · 3e5e78cd
      Kirill Smelkov authored
      Like taking an exact integer log2, upcasting pointers for C-style
      inheritance done in a Plan9 way, and wrappers to functions which should
      never fail.

      Basic setup.py / Makefile to build/install/sdist stuff + bigfile.so skeleton · 5755a6b3
      Kirill Smelkov authored
      It is an early project decision to use gnu99 & Plan9 C extensions, to
      simplify C code.
      
      So far we only build stub wendelin/bigfile/_bigfile.so .
      
      Makefile is introduced because there will be targets which are easier to
      handle at make level. For end users no make knowledge is required -
      usual `python setup.py build|install|...` work, redirecting to make
      where necessary.
      
      As was promised (e870781d "Top-level in-tree import redirector")
      setup.py contains install-time hooks to handle in-tree wendelin.py and
      install it as a module namespace.
      
      For sdist, we just use `git ls-files` info if we are in a checkout.

      Start wendelin.bigfile module · 1e92c921
      Kirill Smelkov authored
      This will be a module to allow users to program custom file-like
      backends and latter memory-map content of files from the backend.
      
      For now just start the module structure.

      Hook in list.h from Linux · a0f940ad
      Kirill Smelkov authored
      Unfortunately in CCAN they made separation of list_head into list_head &
      list_node (for better type safety I suppose), but that leads e.g. to
      inablility to insert element in the middle of the list.
      
      We take the code from util-linux.git (v2.25-165-g9138d6f)[1] which claims
      LGPL license for it, with which we are fine.

      Hook in CCAN · ea890863
      Kirill Smelkov authored
      CCAN[1] is a "Comprehensive C Archive Network" - a collection of useful
      C libraries to use.
      
      Wendelin.core will be a C project in big part, so having CCAN at hand is
      useful.
      
      We hook CCAN as git submodule, without copying it into git repo. Later
      on making source tarball distribution, the code will be injected into
      generated tarball, so there will be no additional dependencies to
      download something from network for end users.

      Top-level in-tree import redirector · e870781d
      Kirill Smelkov authored
      For working copy checkout we would like to work on the source
      right-away, without putting it under additional wendelin/ (and possibly
      /core/) subdirectories.
      
      Add in-tree modules redirector which tweaks plain-python and
      pkg_resources-based imports so that e.g.
      
          import wendelin.bigarray
      
      while in-tree resolves to
      
          bigarray/__init__.py
      
      In installed state, there will be no such redirector, and code will be
      installed with conventional structure.

      Licensing · 66c976ed
      Kirill Smelkov authored
      As a first step we want to make sure the code can be used by open-source
      projects without a problem.
      
      So GPLv3+ with wide exception for all open-source licenses.
