Neal Norwitz adb69fcdff Merge from ast-arena. This reduces the code in Python/ast.c by ~300 lines,
simplifies a lot of error handling code, and fixes many memory leaks.

Jeremy Hylton af68c874a6 Add const to several API functions that take char *.
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Michael W. Hudson aee2e2829d the ast-branch changed the stack discipline of MAKE_CLOSURE, so we need to
bump MAGIC.

Jeremy Hylton 3e0055f8c6 Merge ast-branch to head
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

Guido van Rossum 8ee3e5aa93 - Changes donated by Elemental Security to make it work on AIX 5.3
with IBM's 64-bit compiler (SF patch #1284289).  This also closes SF
  bug #105470: test_pwd fails on 64bit system (Opteron).

sys.modules.

Michael W. Hudson df88846ebc This is my patch:
[ 1180995 ] binary formats for marshalling floats

Adds 2 new type codes for marshal (binary floats and binary complexes), a
new marshal version (2), updates MAGIC and fiddles the de-serializing of
code objects to be less likely to clobber the real reason for failing if
it fails.

Jason Tishler 7961aa6135 Patch #1197318: Cygwin case-sensitive import patch
A problem regarding importing symlinked modules was recently reported on the
Cygwin mailing list:

    http://cygwin.com/ml/cygwin/2005-04/msg00257.html

The following test case demonstrates the problem:

$ ls -l
total 1
lrwxrwxrwx    1 jt       None            6 Apr 23 13:32 bar.py -> foo.py
-rw-r--r--    1 jt       None           24 Apr 18 20:13 foo.py

$ python -c 'import bar'
Traceback (most recent call last):
File "<string>", line 1, in ?
ImportError: No module named bar

Since Cygwin's case_ok() uses a modified version of the Windows's version, the
symlinked bar module actually resolves to file foo.py instead of bar.py. This
obviously causes the matching code to fail (regardless of case).

The patch fixes this problem by making Cygwin use the Mac OS X case_ok()
instead of a modified Window's version.

Raymond Hettinger fd2d1f7870 SF Patch #1013667: Cleanup Peepholer Output
* Make a pass to eliminate NOPs.  Produce code that is more readable,
  more compact, and a tiny bit faster.  Makes the peepholer more flexible
  in the scope of allowable transformations.

* With Guido's okay, bumped up the magic number so that this patch gets
  widely exercised before the alpha goes out.
2004-08-23 23:37:48 +00:00
Tim Peters 1cd701732f PyImport_ExecCodeModuleEx(): remove module from sys.modules in error cases.
PyImport_ReloadModule():  restore the module to sys.modules in error cases.
load_package():  semantic-neutral refactoring from an earlier stab at
                 this patch; giving it a common error exit made the code
                 easier to follow, so retaining that part.
_RemoveModule():  new little utility to delete a key from sys.modules.

Jason Tishler 6bc06eca70 Bug #794140: cygwin builds do not embed
The embed2.diff patch solves the user's problem by exporting the missing
symbols from the Python core so Python can be embedded in another Cygwin
application (well, at lest vim).

Fred Drake 1e5fc55c4d - fix typo
- there's a weird variable name here (zimpimport), but I'll leave that
  for someone that's familiar with the ZIP import support
2003-07-11 15:01:02 +00:00
Neil Schemenauer 00b0966f20 Don't use the module object setattr when importing submodules. Instead,
operate on the module dictionary directly.  This prevents spurious
depreciation warnings from being raised if a submodule name shadows
a builtin name.

Guido van Rossum c4f4ca91e1 Provide access to the import lock, fixing SF bug #580952. This is
mostly from SF patch #683257, but I had to change unlock_import() to
return an error value to avoid fatal error.

Should this be backported?  The patch requested this, but it's a new
feature.

Jack Jansen 9363dca3f8 MacPython-OS9 specific fix: If there are non-string items on sys.path don't try to intern them. This has the theoretical problem that resource filenames on sys.path cannot be unicode objects, but in practice that shouldn't matter. 2003-01-24 16:15:45 +00:00
Just van Rossum 52e14d640b PEP 302 + zipimport:
- new import hooks in import.c, exposed in the sys module
- new module called 'zipimport'
- various changes to allow bootstrapping from zip files

I hope I didn't break the Windows build (or anything else for that
matter), but then again, it's been sitting on sf long enough...

Regarding the latest discussions on python-dev: zipimport sets
pkg.__path__ as specified in PEP 273, and likewise, sys.path item such as
/path/to/Archive.zip/subdir/ are supported again.

Just van Rossum 3eb166b49b Slightly improved version of patch #642578: "Expose PyImport_FrozenModules

and set_frozenmodules().

Guido van Rossum f689492070 Because MWH changed the bytecode again, moved the magic number *back*
to 62011.  This should get the snake-farm to throw away its old .pyc

Walter Dörwald 3430d70e03 Apply diff2.txt from SF patch http://www.python.org/sf/566999
This patch enhances Python/import.c/find_module() so
that unicode objects found in sys.path will be treated
as legal directory names (The current code ignores
anything that is not a str). The unicode name is
converted to str using Py_FileSystemDefaultEncoding.

Guido van Rossum 5e2c5fa1bd imp_load_module(): correct and comment the sense of the test for '+'
in the mode (it's forbidden).
2002-05-30 17:33:07 +00:00
Jeremy Hylton 4ae6faed9f Cover a few corners in the 'U' mode integration to make imp work.
get_file() must convert 'U' to "r" PY_STDIOTEXTMODE before calling
fopen().

imp_load_module() must accept 'r' or 'U' or something with '+'.

Also reflow some long lines.
2002-05-30 17:15:25 +00:00
Jack Jansen c88da1faa5 File modes in filedescr entries are also passed to Python, so we now put "U"
in there, and convert it to "rb" (or "r" for non-universal-newline builds)
before passing it to fopen().

Fixes #561326.
2002-05-28 10:58:19 +00:00
Jack Jansen 7b8c7546eb Mass checkin of universal newline support.
Highlights: import and friends will understand any of \r, \n and \r\n
as end of line. Python file input will do the same if you use mode 'U'.
Everything can be disabled by configuring with --without-universal-newlines.

See PEP278 for details.
