cab75e3e1e Issue #19512: PRINT_EXPR bytecode now uses an identifier to get sys.displayhook

95701bdf40 Issue #19512: Add PyRun_InteractiveOneObject() function 
Only decode the filename once. PyRun_InteractiveOneObject() uses an identifier
for "<string>" string, so the byte string is only decoded once.

d02fbb8f71 Issue #19512: sys_displayhook() now uses an identifier for "builtins" 
dictionary key and only decodes "\n" string once to write a newline.

So "builtins" and "\n" are only decoded once from UTF-8, at the first call.

f6901c8baa Issue #19410: Put back in special-casing of '' for 
importlib.machinery.FileFinder.

While originally moved to stop special-casing '' as PathFinder farther
up the typical call chain now uses the cwd in the instance of '', it
was deemed an unnecessary risk to breaking subclasses of FileFinder to
take the special-casing out.

58f5680462 Issue #18810: Be optimistic with stat calls when seeing if a directory 
exists when checking for a package.

Before there was an isdir check and then various isfile checks for
possible __init__ files when looking for a package.
This change drops the isdir check by leaning
on the assumption that a directory will not contain something named
after the module being imported which is not a directory. If the module
is a package then it saves a stat call. If there is nothing in the
directory with the potential package name it also saves a stat call.
Only if there is something in the directory named the same thing as
the potential package will the number of stat calls increase
(due to more wasteful __init__ checks).

Semantically there is no change as the isdir check moved
down so that namespace packages continue to have no chance of
accidentally collecting non-existent directories.

bb9e481efa Issue #18416: Fix various os calls in importlib.machinery.FileFinder 
now that self.path is no longer forced to '.'.
 2013-10-18 12:01:06 -04:00

27e27f7ee1 Issue #18416: Have importlib.machinery.PathFinder treat '' as the cwd 
and stop importlib.machinery.FileFinder treating '' as '.'.

Previous PathFinder transformed '' into '.' which led to __file__ for
modules imported from the cwd to always be relative paths. This meant
the values of the attribute were wrong as soon as the cwd changed.
This change now means that as long as the site module is run (which
makes all entries in sys.path absolute) then all values for __file__
will also be absolute unless it's for __main__ when specified by file
path in a relative way (modules imported by runpy will have an
absolute path).

Now that PathFinder is no longer treating '' as '.' it only makes
sense for FileFinder to stop doing so as well. Now no transformation
is performed for the directory given to the __init__ method.

Thanks to Madison May for the initial patch.

1805a62f1f Issue #16129: Py_SetStandardStreamEncoding cleanups 
- don't call PyErr_NoMemory with interpreter is not initialised
- note that it's OK to call _PyMem_RawStrDup here
- don't include this in the limited API
- capitalise "IO"
- be explicit that a non-zero return indicates an error
- include versionadded marker in docs

7d270ee05d Issue #16129: Add Py_SetStandardStreamEncoding 
This new pre-initialization API allows embedding
applications like Blender to force a particular
encoding and error handler for the standard IO streams.

Also refactors Modules/_testembed.c to let us start
testing multiple embedding scenarios.
