Brett Cannon 4c14b5de1c #17115,17116: Have modules initialize the __package__ and __loader__
attributes to None.

The long-term goal is for people to be able to rely on these
attributes existing and checking for None to see if they have been
set. Since import itself sets these attributes when a loader does not
the only instances when the attributes are None are from someone
overloading __import__() and not using a loader or someone creating a
module from scratch.

This patch also unifies module initialization. Before you could have
different attributes with default values depending on how the module
object was created. Now the only way to not get the same default set
of attributes is to circumvent initialization by calling
ModuleType.__new__() directly.

Guido van Rossum 98297ee781 Merging the py3k-pep3137 branch back into the py3k branch.
No detailed change log; just check out the change log for the py3k-pep3137
branch.  The most obvious changes:

  - str8 renamed to bytes (PyString at the C level);
  - bytes renamed to buffer (PyBytes at the C level);
  - PyString and PyUnicode are no longer compatible.

I.e. we now have an immutable bytes type and a mutable bytes type.

The behavior of PyString was modified quite a bit, to make it more
bytes-like.  Some changes are still on the to-do list.

Guido van Rossum 00bc0e0a2d Patch #1272, by Christian Heimes and Alexandre Vassalotti.
Changes to make __file__ a proper Unicode object, using the default
filesystem encoding.
This is a bit tricky because the default filesystem encoding isn't
set by the time we import the first modules; at that point we fudge
things a bit.  This is okay since __file__ isn't really used much
except for error reporting.
Tested on OSX and Linux only so far.

Martin v. Löwis 5b222135f8 Make identifiers str (not str8) objects throughout.
This affects the parser, various object implementations,
and all places that put identifiers into C string literals.

In testing, a number of crashes occurred as code would
fail when the recursion limit was reached (such as the
Unicode interning dictionary having key/value pairs where
key is not value). To solve these, I added an overflowed
flag, which allows for 50 more recursions after the
limit was reached and the exception was raised, and
a recursion_critical flag, which indicates that recursion
absolutely must be allowed, i.e. that a certain call
must not cause a stack overflow exception.

There are still some places where both str and str8 are
accepted as identifiers; these should eventually be
removed.

Walter Dörwald 1ab8330827 Add functions PyUnicode_Append() and PyUnicode_AppendAndDel() that mirror
PyString_Concat() and PyString_ConcatAndDel() (the name PyUnicode_Concat()
was already taken).

Change PyObject_Repr() to always return a unicode object.

Update all repr implementations to return unicode objects.

Add a function PyObject_ReprStr8() that calls PyObject_Repr() and converts
the result to an 8bit string.

Use PyObject_ReprStr8() where using PyObject_Repr() can't be done
straightforward.

Guido van Rossum f15a29f975 More coding by random modification.
Encoding now return bytes instead of str8.
eval(), exec(), compile() now accept unicode or bytes.
2007-05-04 00:41:39 +00:00
Guido van Rossum 572dbf8f13 Checkpoint. Manipulated things so that string literals are always
unicode, and a few other compensating changes, e.g. str <- unicode,
chr <- unichr, and repr() of a unicode string no longer starts
with 'u'.  Lots of unit tests are broken, but some basic things
work, in particular distutils works so the extensions can be built,
and test_builtin.py works.

Thomas Wouters 49fd7fa443 Merge p3yk branch with the trunk up to revision 45595. This breaks a fair
number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html

Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:

test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec

This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.

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 1fd00a1b71 Make the word "module" appear in the error string for calling the
module type with silly arguments.  (The exact name can be quibbled
over, if you care).

This was partially inspired by bug #1014215 and so on, but is also
just a good idea.

Neil Schemenauer 4e3363e884 Warn about creating global variables by __setattr__ that shadow builtin

dictionary can be modified directly.

Guido van Rossum ed3e09f289 Add a docstring to the module type. 2002-06-04 06:02:35 +00:00
Guido van Rossum c3a787e090 Surprising fix for SF bug 563060: module can be used as base class.
Change the module constructor (module_init) to have the signature
__init__(name:str, doc=None); this prevents the call from type_new()
to succeed.  While we're at it, prevent repeated calling of
module_init for the same module from leaking the dict, changing the
semantics so that __dict__ is only initialized if NULL.

Also adding a unittest, test_module.py.

This is an incompatibility with 2.2, if anybody was instantiating the
module class before, their argument list was probably empty; so this
can't be backported to 2.2.x.

Guido van Rossum cd637aae56 Fix for SF bug #529050 - ModuleType.__new__ crash.
There were several places that assumed the md_dict field was always
set, but it needn't be.  Fixed these to be more careful.

I changed PyModule_GetDict() to initialize md_dict to a new dictionary
if it's NULL.

Bugfix candidate.

Neil Schemenauer f23473f008 Add missing "static" declarations (found by "make smelly"). 2001-10-21 22:28:58 +00:00
Guido van Rossum 9475a2310d Enable GC for new-style instances. This touches lots of files, since
many types were subclassable but had a xxx_dealloc function that
called PyObject_DEL(self) directly instead of deferring to
self->ob_type->tp_free(self).  It is permissible to set tp_free in the
type object directly to _PyObject_Del, for non-GC types, or to
_PyObject_GC_Del, for GC types.  Still, PyObject_DEL was a tad faster,
so I'm fearing that our pystone rating is going down again.  I'm not
sure if doing something like

void xxx_dealloc(PyObject *self)
{
	if (PyXxxCheckExact(self))
		PyObject_DEL(self);
	else
		self->ob_type->tp_free(self);
}

is any faster than always calling the else branch, so I haven't
attempted that -- however those types whose own dealloc is fancier
(int, float, unicode) do use this pattern.
2001-10-05 20:51:39 +00:00
Guido van Rossum 6f7993765a Add optional docstrings to member descriptors. For backwards
compatibility, this required all places where an array of "struct
memberlist" structures was declared that is referenced from a type's
tp_members slot to change the type of the structure to PyMemberDef;
"struct memberlist" is now only used by old code that still calls
PyMember_Get/Set.  The code in PyObject_GenericGetAttr/SetAttr now
calls the new APIs PyMember_GetOne/SetOne, which take a PyMemberDef
argument.

As examples, I added actual docstrings to the attributes of a few
types: file, complex, instance method, super, and xxsubtype.spamlist.

Also converted the symtable to new style getattr.

Barry Warsaw 2907fe6ce7 module_repr(): Instead of fixing the maximum buf size to 400,
calculate it on the fly.  This way even modules with long package
    names get an accurate repr instead of a truncated one.  The extra
    malloc/free cost shouldn't be a problem in a repr function.

Guido van Rossum f1dc0615e9 Add internal routine _PyModule_Clear(), which does approximately what
clear_carefully() used to do in import.c.  Differences: leave only
__builtins__ alone in the 2nd pass; and don't clear the dictionary (on
the theory that as long as there are references left to the
dictionary, those might be destructors that might expect __builtins__
to be alive when they run; and __builtins__ can't normally be part of
a cycle).

Guido van Rossum 1d5735e846 Merge back to main trunk 1994-08-30 08:27:36 +00:00
Guido van Rossum c45611d0e3 * import.c (get_module): total rewrite, to ensure proper search order: for
each dir in sys.path, try each possible extension.  (Note: C extensions
  are loaded before Python modules in the same directory, to allow having
  a C version used when dynamic loading is supported and a Python version
  as a back-up.)
* import.c (reload_module): test for error from getmodulename()
* moduleobject.c: implement module name as dict entry '__name__' instead
  of special-casing it in module_getattr(); this way a module (or
  function!) can access its own module name, and programs that know what
  they are doing can rename modules.
* stdwinmodule.c (initstdwin): strip ".py" suffix of argv[0].
1993-11-17 22:58:56 +00:00
Guido van Rossum eb6b33a837 * classobject.c: in instance_getattr, don't make a method out of a
function found as instance data.
* socketmodule.c: added 'flags' argument sendto/recvfrom, rewrite
  argument parsing in send/recv.
* More changes related to access (terminology change: owner instead of
  class; allow any object as owner; local/global variables are owned
  by their dictionary, only class/instance data is owned by the class;
  "from...import *" now only imports objects with public access; etc.)
1993-05-25 09:38:27 +00:00
Guido van Rossum 81daa32c15 Access checks now work, at least for instance data (not for methods
yet).  The class is now passed to eval_code and stored in the current
frame.  It is also stored in instance method objects.  An "unbound"
instance method is now returned when a function is retrieved through
"classname.funcname", which when called passes the class to eval_code.
1993-05-20 14:24:46 +00:00
Guido van Rossum 25831652fd Several changes in one:
(1) dictionaries/mappings now have attributes values() and items() as
well as keys(); at the C level, use the new function mappinggetnext()
to iterate over a dictionary.

(2) "class C(): ..." is now illegal; you must write "class C: ...".

(3) Class objects now know their own name (finally!); and minor
improvements to the way how classes, functions and methods are
represented as strings.

(4) Added an "access" statement and semantics.  (This is still
experimental -- as long as you don't use the keyword 'access' nothing
should be changed.)
1993-05-19 14:50:45 +00:00
Guido van Rossum 9bfef44d97 * Changed all copyright messages to include 1993.
* Stubs for faster implementation of local variables (not yet finished)
* Added function name to code object.  Print it for code and function
  objects.  THIS MAKES THE .PYC FILE FORMAT INCOMPATIBLE (the version
  number has changed accordingly)
* Print address of self for built-in methods
* New internal functions getattro and setattro (getattr/setattr with
  string object arg)
* Replaced "dictobject" with more powerful "mappingobject"
* New per-type functio tp_hash to implement arbitrary object hashing,
  and hashobject() to interface to it
* Added built-in functions hash(v) and hasattr(v, 'name')
* classobject: made some functions static that accidentally weren't;
  added __hash__ special instance method to implement hash()
* Added proper comparison for built-in methods and functions
1993-03-29 10:43:31 +00:00
Guido van Rossum 7066dd75c5 * Makefile: added IMGFILE; moved some stuff around.
* flmodule.c: added some missing functions; changed readonly flags of
  some data members based upon FORMS documentation.
* listobject.c: fixed int/long arg lint bug (bites PC compilers).
* several: removed redundant print methods (repr is good enough).
* posixmodule.c: added (still experimental) process group functions.
