      gpython: Fix pymain to properly setup sys.path (take 2) · fb98e594
      Kirill Smelkov authored
      This continues 6b4990f6 (gpython: Fix pymain to properly setup
      sys.path[0]) - now we add test and verify that gpython actually sets
      sys.path in the same way as underlying python does:
      
      - don't add directory of gpython to sys.path
      - for `gpython file` add to sys.path[0] realpath(dir(file)) instead of
        dir(file)  (see PySys_SetArgvEx for the reference, and else - if we do
        not make this change - added test breaks)
      - for `gpython -m mod` add to sys.path[0] realpath('') instead of ''.
        This exactly matches PY3 behaviour, while PY2 behaviour is to add ''
        However PY3 behaviour
      
          * is more sane, and
          * fixes test_defer_excchain_traceback on py27-gevent
      
        -> so we stick to it.
      
      Now all tests pass again.

      gpython: Preimport golang and gevent from exactly the same place as std python would do · 1f6f31cd
      Kirill Smelkov authored
      GPython preimports golang and gevent, but until now, it was preimporting
      them before adjusting sys.path according to given -c/-m/file/... And
      this was leading to difference in behaviour with standard Python where
      e.g. `import golang` might result in different files loaded if e.g.
      golang/ is there on cwd and -c/-m was given.
      
      -> Rework gpython startup so that golang/gevent preimport happens after
      sys.path initialization.
      
      This fixes `tox -e py27-gevent` which was previously failing on
      test_defer_excchain_dump_pytest / test_defer_excchain_dump_ipython
      because dumped paths were different than expected ones.
      
      It, however, breaks test_defer_excchain_traceback on py27-gevent.  ->
      We'll do more fixups to sys.path handling in the next patch which will
      fix that failure as well.

      gpython: Reorganize options parsing · b47edf42
      Kirill Smelkov authored
      Reorganize parsiong of command line options so that first all options are
      parsed in a loop, and only after that a module/file/command is executed.
      
      This is needed as preparatory step for next patch: there we'll add
      support for -W, and `-W arg` can be given multiple times and has to be
      processed multiple times by creating multiple corresponding warning
      filters. Because those warning filters has to be applied uniformly to
      all 4 codepaths of execution phase (-m/-c/file/interactive console), it
      makes sense to move execution phase to after options parsing and inject
      common runtime preparatory steps right before that.
      
      This logic generally applies not only to -W, but to all other python
      options - e.g. -Q,-u,...

      gpython: Add way to run it with threads runtime · a6b993c8
      Kirill Smelkov authored
      Until now gpython was always activating gevent on startup + adding
      goodness such as "always UTF-8 default encoding"; go, chan, b/u and
      friends available from builtin namespace, etc... While those goodness
      are sometimes useful on their own, it is not always appropriate to force
      a project to switch from threads to gevent.
      
      For this reason add a flag to select which runtime - either gevent
      or threads - gpython should use.
      
      	gpython -Xgpython.runtime=gevent	selects gevent,
      
      while
      
      	gpython -Xgpython.runtime=threads	selects threads.
      
      Gevent remains the default.
      
      It is also possible to specify desired runtime via $GPYTHON_RUNTIME
      environment variable.

      golang: tests: assertDoc: Include ~/... into PYGOLANG normalization · 42ab98a6
      Kirill Smelkov authored
      assertDoc normalizes paths in compared texts with the idea for etalon
      output to contain PYGOLANG instead of whatever actual path there will be
      when testing the package. This already works.
      
      However IPython, when dumping tracebacks, tries to shorten paths and
      abbreviate $HOME with ~ in them. This breaks normalization which misses
      to convert prefix of those paths into PYGOLANG.
      
      -> Fix it by teaching assertDoc to also handle paths that start with ~
      and correctly normalize them.
      
      This will be needed in the next patch where we will add tests for how
      ipython and pytest dump tracebacks for chained exceptions.

      golang: Teach qq to be usable with both bytes and str format whatever type qq argument is · edc7aaab
      Kirill Smelkov authored
      qq is used to quote strings or byte-strings. The following example
      illustrates the problem we are currently hitting in zodbtools with
      Python3:
      
          >>> "hello %s" % qq("мир")
          'hello "мир"'
      
          >>> b"hello %s" % qq("мир")
          Traceback (most recent call last):
            File "<stdin>", line 1, in <module>
          TypeError: %b requires a bytes-like object, or an object that implements __bytes__, not 'str'
      
          >>> "hello %s" % qq(b("мир"))
          'hello "мир"'
      
          >>> b"hello %s" % qq(b("мир"))
          Traceback (most recent call last):
            File "<stdin>", line 1, in <module>
          TypeError: %b requires a bytes-like object, or an object that implements __bytes__, not 'str'
      
      i.e. one way or another if type of format string and what qq returns do not
      match it creates a TypeError.
      
      We want qq(obj) to be useable with both string and bytestring format.
      
      For that let's teach qq to return special str- and bytes- derived types that
      know how to automatically convert to str->bytes and bytes->str via b/u
      correspondingly. This way formatting works whatever types combination it was
      for format and for qq, and the whole result has the same type as format.
      
      For now we teach only qq to use new types and don't generally expose
      _str and _unicode to be returned by b and u yet. However we might do so
      in the future after incrementally gaining a bit more experience.
