      [test] Disable extends-cache.txt test · 8448ae9a
      Xavier Thompson authored
      This test asserts buildout's behavior with regards to download options,
      and this was changed by the new algorithm for extends. Tests for the
      new behavior have not been written yet.

      [feat] Reimplement the extends algorithm · 7fded038
      Xavier Thompson authored
      The new algorithm avoids fetching the same extended file more than once
      and correctly handles overriding values and += and -=:
      
      The new algorithm starts as if there was a buildout file containing
      
      ```
      [buildout]
      extends =
        user/defaults.cfg # if it exists
        buildout.cfg # if it exists
        command_line_extends.cfg # if passed on the command line
      ```
      
      The files are then fetched in depth-first-search postorder and fetching
      child nodes in the order given by the extends directive, ignoring files
      that have already been fetched.
      
      The buildout dicts are then collected in order, and this linearisation
      is then merged at the end, overriding the first configs collected with
      the later ones. The first dict in the linearisation is not from a file,
      but the dict of buildout's (hardcoded) defaults. This is equivalent to
      acting as though every file that does not extend anything extends these
      defaults.
      
      The first time a file must be downloaded from a url, the linearisation
      is merged with the configs already collected, and the resulting options
      are then used to determine the download options for this download, and
      every subsequent download.
      
      This is a break with buildout's current logic for download options.
      
      By analogy with classes in Python, we are computing a linearisation of
      the class hierarchy to determine the method resolution order (MRO).
      This algorithm is not the same as Python's MRO since Python 2.3 (C3).
      
      It could be good to switch to a C3 linearisation like Python.

      [feat] Install libnetworkcache in bootstrap · d9d46918
      Xavier Thompson authored
      If slapos.libnetworkcache is importable, install it in bootstrap
      as though it were a dependency of zc.buildout.
      
      This is a hack to propagate libnetworkcache as a soft dependency.

      [feat] Respect pinned versions in bootstrap · d2a297c5
      Xavier Thompson authored
      If zc.buildout or its dependencies have pinned versions that do not
      match the currently running versions, they are now installed in the
      local eggs directory from scratch according to the pinned versions.
      
      In offline mode this merely ensures that versions that satisfy the
      requirements are already available. This is the case when the eggs
      are already installed, or when the running versions are a match to
      the pinned versions or the absence of a pinned version.
      
      If after this matching versions of zc.buildout and its dependencies
      are not located in the local eggs or develop-eggs directories, they
      are copied there as was already the case before.

      [bug] Fix accidental changes to PYTHONPATH in os.environ · 03173a09
      Xavier Thompson authored
      When generating an environment dict for subprocess calls to pip,
      os.environ was accidentally modified despite efforts to copy it
      and modify only the copy, as copy.copy(os.environ) is not enough.
