Christian Heimes 81caa790b6 Quick 'n dirty hack: Increase the magic by 2 to force a rebuild of pyc/pyo files on the build bots 2008-03-27 09:02:33 +00:00

Christian Heimes 3c60833e1e Patch #2477: Added from __future__ import unicode_literals
The new PyParser_*Ex() functions are based on Neal's suggestion and initial patch. The new __future__ feature makes all '' and r'' unicode strings. b'' and br'' stay (byte) strings.

Nick Coghlan 7af53be66f Speed up with statements by storing the __exit__ method on the stack instead of in a temp variable (bumps the magic number for pyc files) 2008-03-07 14:13:28 +00:00

Raymond Hettinger effde12f5f Speed-up dictionary constructor by about 10%.
New opcode, STORE_MAP saves the compiler from awkward stack manipulations
and specializes for dicts using PyDict_SetItem instead of PyObject_SetItem.

Georg Brandl 98775dfebc Bug #1550983: emit better error messages for erroneous relative

Neal Norwitz dac090d3e6 Bug #1520864 (again): unpacking singleton tuples in list comprehensions and
generator expressions (x for x, in ... ) works again.

Sigh, I only fixed for loops the first time, not list comps and genexprs too.
I couldn't find any more unpacking cases where there is a similar bug lurking.

This code should be refactored to eliminate the duplication.  I'm sure
the listcomp/genexpr code can be refactored.  I'm not sure if the for loop
can re-use any of the same code though.

Will backport to 2.5 (the only place it matters).

Neal Norwitz 3cb31ac704 cpathname could be NULL if it was longer than MAXPATHLEN. Don't try
to write the .pyc to NULL.

Check results of PyList_GetItem() and PyModule_GetDict() are not NULL.

Neal Norwitz 9a70f95ee8 There were really two issues 2006-08-04 05:12:19 +00:00
Neal Norwitz 4ffedadb10 Bug #1191458: tracing over for loops now produces a line event
on each iteration.  I'm not positive this is the best way to handle
this.  I'm also not sure that there aren't other cases where
the lnotab is generated incorrectly.  It would be great if people
that use pdb or tracing could test heavily.

Also:
 * Remove dead/duplicated code that wasn't used/necessary
   because we already handled the docstring prior to entering the loop.
 * add some debugging code into the compiler (#if 0'd out).

Phillip J. Eby f7575d0cb7 Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
with PEP 302.  This was fixed by adding an ``imp.NullImporter`` type that is
used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
excessive filesystem operations during imports.

Georg Brandl f4ef11659c Need for speed: Patch #921466 : sys.path_importer_cache is now used to cache valid and
invalid file paths for the built-in import machinery which leads to
  fewer open calls on startup.

  Also fix issue with PEP 302 style import hooks which lead to more open()
  calls than necessary.

Georg Brandl 684fd0c8ec Replace PyObject_CallFunction calls with only object args
with PyObject_CallFunctionObjArgs, which is 30% faster.

Thomas Wouters 9df4e6f673 - Add new Warning class, ImportWarning
- Warn-raise ImportWarning when importing would have picked up a directory
   as package, if only it'd had an __init__.py. This swaps two tests (for
   case-ness and __init__-ness), but case-test is not really more expensive,
   and it's not in a speed-critical section.

 - Test for the new warning by importing a common non-package directory on
   sys.path: site-packages

 - In regrtest.py, silence warnings generated by the build-environment
   because Modules/ (which is added to sys.path for Setup-created modules)
   has 'zlib' and '_ctypes' directories without __init__.py's.

Anthony Baxter ac6bd46d5c spread the extern "C" { } magic pixie dust around. Python itself builds now
using a C++ compiler. Still lots and lots of errors in the modules built by
setup.py, and a bunch of warnings from g++ in the core.
