bpo-39481: PEP 585 for difflib, filecmp, fileinput (#19422) 2020-04-09 21:47:31 -07:00
Pablo Galindo 293dd23477
Remove binding of captured exceptions when not used to reduce the chances of creating cycles (GH-17246)
Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles.

See for example GH-13135

  Make map() and filter() identical to itertools.imap() and .ifilter(),
  respectively.

  I fixed two bootstrap issues, due to the dynamic import of itertools:

  1. Starting python requires that map() and filter() are not used until
     site.py has added build/lib.<arch> to sys.path.
  2. Building python requires that setup.py and distutils and everything
     they use is free of map() and filter() calls.

  Beyond this, I only fixed the tests in test_builtin.py.
  Others, please help fixing the remaining tests that are now broken!
  The fixes are usually simple:
  a. map(None, X) -> list(X)
  b. map(F, X) -> list(map(F, X))
  c. map(lambda x: F(x), X) -> [F(x) for x in X]
  d. filter(F, X) -> list(filter(F, X))
  e. filter(lambda x: P(x), X) -> [x for x in X if P(x)]

  Someone, please also contribute a fixer for 2to3 to do this.
  It can leave map()/filter() calls alone that are already
  inside a list() or sorted() call or for-loop.

  Only in rare cases have I seen code that depends on map() of lists
  of different lengths going to the end of the longest, or on filter()
  of a string or tuple returning an object of the same type; these
  will need more thought to fix.

Guido van Rossum cc2b016125 - PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
and .keys(), .items(), .values() return dict views.

The dict views aren't fully functional yet; in particular, they can't
be compared to sets yet.  but they are useful as "iterator wells".

There are still 27 failing unit tests; I expect that many of these
have fairly trivial fixes, but there are so many, I could use help.

Guido van Rossum be19ed77dd Fix most trivially-findable print statements.
There's one major and one minor category still unfixed:
doctests are the major category (and I hope to be able to augment the
refactoring tool to refactor bona fide doctests soon);
other code generating print statements in strings is the minor category.

(Oh, and I don't know if the compiler package works.)

* Changed variable name from 'list' to 'flist'.

  faster dispatch dictionary that maps attrs to methods.
* Simplified and sped comparison logic by using
  ifilter, ifilterfalse, and dict.fromkeys.
* Used True and False rather than 1 and 0.

Guido van Rossum 63b08ac2f7 Whoops! We just discovered that Gordon's revamp of this module was
accidentally wiped out by Ping's patch (which shouldn't have affected
this file at all, had Ping done a cvs update).

This checkin restores Gordon's version, with Fredrik's change merged
back in.

Guido van Rossum 1916b35f58 Fredrik Lundh:
The new filecmp module has an optional argument called use_statcache
which is documented as a true/false value, but used as an tuple index.

This patches replaces the tuple stuff with a good old if- statement,
and also removes a few other tuple pack/unpack constructs (if not
else, this saves a few bytes in the PYC file, and a few microseconds
when using the module ;-).

Guido van Rossum 54f22ed30b More trivial comment -> docstring transformations by Ka-Ping Yee,
who writes:

Here is batch 2, as a big collection of CVS context diffs.
Along with moving comments into docstrings, i've added a
couple of missing docstrings and attempted to make sure more
module docstrings begin with a one-line summary.

I did not add docstrings to the methods in profile.py for
fear of upsetting any careful optimizations there, though
i did move class documentation into class docstrings.

The convention i'm using is to leave credits/version/copyright
type of stuff in # comments, and move the rest of the descriptive
stuff about module usage into module docstrings.  Hope this is
okay.
