Brett Cannon ed672d6872 Make path manipulation more robust for platforms with alternative path 
separators.
 2012-04-20 21:19:53 -04:00
Brett Cannon 24117a748b Issue #13959: Keep imp.get_magic() in C code, but cache in importlib 
for performance. While get_magic() could move to Lib/imp.py, having to
support PyImport_GetMagicNumber() would lead to equal, if not more, C
code than sticking with the status quo.

Brett Cannon 1b5123aae5 Issue #14628: Document the fact that import always returns the module 
as found in sys.modules and not as what the loader returns (even
though it is required to by PEP 302).

Brett Cannon 1032af95ff Issue #14585: test_import now runs all tests under 
importlib.test.import_ using builtins.__import__() instead of just the
relative import tests.

Brett Cannon 3dfc22cc04 Issue #14599: Support ImportError.path on AIX and HPUX when loading 
extension modules.

Brett Cannon f0434e647a Issue #14599: Generalize a test for ImportError.path and add support 
in Python/dynload_shlibs.c.

This should fix the remaining importlib test failure on Windows.
Support in AIX and HP-UX will be in a separate checkin.

Stefan Krah 9d3a5aeabe Defensive programming: mpd_isspecial(r) already implies mpd_isspecial(q), but 
this is more readable.
 2012-04-20 21:00:31 +02:00
Stefan Krah 3c23a87e58 The divmod function for large numbers now has an ACL2 proof. Related changes: 
1) Rename _mpd_qbarrett_divmod into _mpd_base_ndivmod: The function is
     only marginally related to either Barrett's algorithm or to the version
     in Hasselstrom's paper.

  2) In places where the proof assumes exact operations, use new versions of
     add/sub/multiply that set NaN/Invalid_operation if this condition is
     not met. According to the proof this cannot happen, so this should be
     regarded as an extra safety net.

  3) Raise Division_impossible for operands with a number of digits greater
     than MPD_MAX_PREC. This facilitates the audit of the function and can
     practically only occur in the 32-bit version under conditions where
     a MemoryError is already imminent.

  4) Use _mpd_qmul() in places where the result can exceed MPD_MAX_PREC in
     a well defined manner.

  5) Test for mpd_isspecial(qq) in a place where the addition of one
     can theoretically trigger a Malloc_error.

  6) Remove redundant code in _mpd_qdivmod().

  7) Add many comments.

the file suffix's case into account, even when doing a case-sensitive
import.

Brett Cannon 91900eaf96 Have importlib.test.regrtest clear sys.path_importer_cache to make

Victor Stinner b0b224233e Issue #14385: Support other types than dict for __builtins__ 
It is now possible to use a custom type for the __builtins__ namespace, instead
of a dict. It can be used for sandboxing for example.  Raise also a NameError
instead of ImportError if __build_class__ name if not found in __builtins__.

Stefan Krah c51b7fd65b 1) Simplify comment -- one has to read the complete proof (available in ACL2) 
in order to understand the algorithm anyway.

2) v->exp == -v->digits may be assumed.

3) Fix comment (v always shares data with a).

Stefan Krah 6369f77d20 Support mythical ones' complement machines. 2012-04-18 17:57:56 +02:00
Stefan Krah 140893cbaa The previous code is correct, but hard to verify: The libmpdec documentation 
rightfully states that an mpd_t with a coefficient flagged as MPD_CONST_DATA
must not be in the position of the result operand. In this particular case
several assumptions guarantee that a resize will never occur in all possible
code paths, which was the reason for using MPD_CONST_DATA and saving an
instruction by omitting the initialization of tmp.alloc.

For readability, tmp is now flagged as MPD_STATIC_DATA and tmp.alloc
is initialized.
