Martin v. Löwis cdc4451222 Include <unistd.h> in Python.h. Fixes #500924. 2002-01-12 11:05:12 +00:00
Jeremy Hylton 733c8935f9 Fix for SF bug [ #492403 ] exec() segfaults on closure's func_code
Based on the patch from Danny Yoo.  The fix is in exec_statement() in
ceval.c.

There are also changes to introduce use of PyCode_GetNumFree() in
several places.

Guido van Rossum 03290ecbf1 Implement isinstance(x, (A, B, ...)). Note that we only allow tuples,
not other sequences (then we'd have to except strings, and we'd still
be susceptible to recursive attacks).
2001-10-07 20:54:12 +00:00
Tim Peters 742dfd6f17 Get rid of builtin_open() entirely (the C code and docstring, not the
builtin function); Guido pointed out that it could be just another
name in the __builtin__ dict for the file constructor now.

Tim Peters 7eea37e831 At Guido's suggestion, here's a new C API function, PyObject_Dir(), like
__builtin__.dir().  Moved the guts from bltinmodule.c to object.c.
2001-09-04 22:08:56 +00:00
Tim Peters 37a309db70 builtin_dir(): Treat classic classes like types. Use PyDict_Keys instead
of PyMapping_Keys because we know we have a real dict.  Tolerate that
objects may have an attr named "__dict__" that's not a dict (Py_None
popped up during testing).

test_descr.py, test_dir():  Test the new classic-class behavior; beef up
the new-style class test similarly.

test_pyclbr.py, checkModule():  dir(C) is no longer a synonym for
C.__dict__.keys() when C is a classic class (looks like the same thing
that burned distutils! -- should it be *made* a synoym again?  Then it
would be inconsistent with new-style class behavior.).
2001-09-04 01:20:04 +00:00
Tim Peters 5d2b77cf31 Make dir() wordier (see the new docstring). The new behavior is a mixed
bag.  It's clearly wrong for classic classes, at heart because a classic
class doesn't have a __class__ attribute, and I'm unclear on whether
that's feature or bug.  I'll repair this once I find out (in the
meantime, dir() applied to classic classes won't find the base classes,
while dir() applied to a classic-class instance *will* find the base
classes but not *their* base classes).

Please give the new dir() a try and see whether you love it or hate it.
The new dir([]) behavior is something I could come to love.  Here's
something to hate:

>>> class C:
...     pass
...
>>> c = C()
>>> dir(c)
['__doc__', '__module__']
>>>

The idea that an instance has a __doc__ attribute is jarring (of course
it's really c.__class__.__doc__ == C.__doc__; likewise for __module__).

OTOH, the code already has too many special cases, and dir(x) doesn't
have a compelling or clear purpose when x isn't a module.

Tim Peters 9fa96bed6f Fix for bug [#452230] future division isn't propagated.
builtin_eval wasn't merging in the compiler flags from the current frame;
I suppose we never noticed this before because future division is the
first future-feature that can affect expressions (nested_scopes and
generators had only statement-level effects).

Marc-André Lemburg ae21df59c3 Undoing the UCS-4 patch addition which caused unichr() to return
surrogates for Unicode code points outside range(0x10000) on narrow
Python builds.
2001-07-26 16:29:25 +00:00
Tim Peters 5ba5866281 Part way to allowing "from __future__ import generators" to communicate
that info to code dynamically compiled *by* code compiled with generators
enabled.  Doesn't yet work because there's still no way to tell the parser
that "yield" is OK (unlike nested_scopes, the parser has its fingers in
this too).
Replaced PyEval_GetNestedScopes by a more-general
PyEval_MergeCompilerFlags.  Perhaps I should not have?  I doubted it was
*intended* to be part of the public API, so just did.

2001-06-27 18:59:43 +00:00
Guido van Rossum 236d8b7974 Cosmetic changes to MvL's change to unichr():
- the correct range for the error message is range(0x110000);

- put the 4-byte Unicode-size code inside the same else branch as the
  2-byte code, rather generating unreachable code in the 2-byte case.

- Don't hide the 'else' behine the '}'.

(I would prefer that in 4-byte mode, any value should be accepted, but
reasonable people can argue about that, so I'll put that off.)

Tim Peters 8572b4fedf Generalize zip() to work with iterators.
NEEDS DOC CHANGES.
More AttributeErrors transmuted into TypeErrors, in test_b2.py, and,
again, this strikes me as a good thing.
This checkin completes the iterator generalization work that obviously
needed to be done.  Can anyone think of others that should be changed?

Tim Peters f4848dac41 Make PyIter_Next() a little smarter (wrt its knowledge of iterator

2001-05-04 04:39:21 +00:00
Tim Peters 4e9afdca39 Generalize map() to work with iterators.
NEEDS DOC CHANGES.
Possibly contentious:  The first time s.next() yields StopIteration (for
a given map argument s) is the last time map() *tries* s.next().  That
is, if other sequence args are longer, s will never again contribute
anything but None values to the result, even if trying s.next() again
could yield another result.  This is the same behavior map() used to have
wrt IndexError, so it's the only way to be wholly backward-compatible.
I'm not a fan of letting StopIteration mean "try again later" anyway.

Tim Peters 748b8bbe02 Fix buglet reported on c.l.py: map(fnc, file.xreadlines()) blows up.
Also a 2.1 bugfix candidate (am I supposed to do something with those?).
Took away map()'s insistence that sequences support __len__, and cleaned
up the convoluted code that made it *look* like it really cared about
__len__ (in fact the old ->len field was only *used* as a flag bit, as
the main loop only looked at its sign bit, setting the field to -1 when
IndexError got raised; renamed the field to ->saw_IndexError instead).

Guido van Rossum 59d1d2b434 Iterators phase 1. This comprises:
new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER
new C API PyObject_GetIter(), calls tp_iter
new builtin iter(), with two forms: iter(obj), and iter(function, sentinel)
new internal object types iterobject and calliterobject
new exception StopIteration
new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py)
new magic number for .pyc files
new special method for instances: __iter__() returns an iterator
iteration over dictionaries: "for x in dict" iterates over the keys
iteration over files: "for x in file" iterates over lines

2001-04-20 19:13:02 +00:00
Tim Peters 388ed08cbf SF patch #413552 - Premature decref on object
Jeffery Collins pointed out that filterstring decrefs a character object
before it's done using it.  This works by accident today because another
module always happens to have an active reference too at the time.  The
accident doesn't work after his Pippy modifications, and since it *is*
an accident even in the mainline Python, it should work by design there too.
The patch accomplishes that.

Jeremy Hylton bc32024769 Extend support for from __future__ import nested_scopes
If a module has a future statement enabling nested scopes, they are
also enable for the exec statement and the functions compile() and
execfile() if they occur in the module.

If Python is run with the -i option, which enters interactive mode
after executing a script, and the script it runs enables nested
scopes, they are also enabled in interactive mode.

XXX The use of -i with -c "from __future__ import nested_scopes" is
not supported.  What's the point?

To support these changes, many function variants have been added to
pythonrun.c.  All the variants names end with Flags and they take an
extra PyCompilerFlags * argument.  It is possible that this complexity
will be eliminated in a future version of the interpreter in which
nested scopes are not optional.

Marc-André Lemburg d1ba443206 This patch adds a new Python C API called PyString_AsStringAndSize()
which implements the automatic conversion from Unicode to a string
object using the default encoding.

The new API is then put to use to have eval() and exec accept
Unicode objects as code parameter. This closes bugs #110924
and #113890.

As side-effect, the traditional C APIs PyString_Size() and
PyString_AsString() will also accept Unicode objects as
parameters.

Guido van Rossum 0df002c45b Add three new APIs: PyRun_AnyFileEx(), PyRun_SimpleFileEx(),
PyRun_FileEx().  These are the same as their non-Ex counterparts but
have an extra argument, a flag telling them to close the file when
done.

Then this is used by Py_Main() and execfile() to close the file after
it is parsed but before it is executed.

Adding APIs seems strange given the feature freeze but it's the only
way I see to close the bug report without incompatible changes.

Guido van Rossum 106f2dae86 Trent Mick:
Various small fixes to the builtin module to ensure no buffer
overflows.

- chunk #1:
Proper casting to ensure no truncation, and hence no surprises, in the
comparison.

- chunk #2:
The id() function guarantees a unique return value for different
objects.  It does this by returning the pointer to the object. By
returning a PyInt, on Win64 (sizeof(long) < sizeof(void*)) the pointer
is truncated and the guarantee may be proven false. The appropriate
return function is PyLong_FromVoidPtr, this returns a PyLong if that
is necessary to return the pointer without truncation.

[GvR: note that this means that id() can now return a long on Win32
platforms.  This *might* break some code...]

- chunk #3:
Ensure no overflow in raw_input(). Granted the user would have to pass
in >2GB of data but it *is* a possible buffer overflow condition.

Fix memory leak in initializing __debug__.
2000-06-20 04:54:19 +00:00
Barry Warsaw 78e6c671db All the exception building related stuff has been moved out of this
module and into _exceptions.c.  This includes all the PyExc_* globals,
the bltin_exc table, init_class_exc(), fini_instances(),
finierrors().

Renamed _PyBuiltin_Init_1() to _PyBuiltin_Init() since the two phase
initializations are necessary any more.

Removed as obsolete _PyBuiltin_Init_2(), _PyBuiltin_Fini_1() and
_PyBuiltin_Fini_2().
2000-05-25 23:15:05 +00:00
Barry Warsaw 1226588e57 bltin_exc: Removed the leaf_exc flag in the structure, which was only
used to build the fallback string-based exception.
2000-05-25 03:18:53 +00:00
Fred Drake c640b18d96 M.-A. Lemburg <mal@lemburg.com>:
Fixed docs according to the new behaviour (the Unicode
encoding is no longer fixed to UTF-8).
2000-05-09 19:55:16 +00:00
Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)
2000-05-03 23:44:39 +00:00
Guido van Rossum a7cfca23e1 A bit of cleanup:
- When 'import exceptions' fails, don't suggest to use -v to print the traceback;
  this doesn't actually work.
- Remove comment about fallback to string exceptions.
- Remove a PyErr_Occurred() check after all is said and done that can
  never trigger.
- Remove static function newstdexception() which is no longer called.
2000-05-03 22:03:46 +00:00
Barry Warsaw 48719d3d1f _PyBuiltin_Init_2(): Remove the misleading comment. 2000-05-02 19:24:39 +00:00
Barry Warsaw 47eeb9bdad initerrors(): Remove this function. String-based standard exceptions
are no longer supported (i.e. -X option is removed).

_PyBuiltin_Init_1(): Don't call initerrors().  This does mean that it
is possible to raise an ImportError before that exception has been
initialized, say because exceptions.py can't be found, or contains
bogosity.  See changes to errors.c for how this is handled.

_PyBuiltin_Init_2(): Don't test Py_UseClassExceptionsFlag, just go
ahead and initialize the class-based standard exceptions.  If this
fails, we throw a Py_FatalError.
2000-05-02 19:24:06 +00:00
Fred Drake 078b24f000 When refering to Unicode characters in exception messages and
docstrings, the documentation guidelines call for "Unicode", not
"unicode".  Comply.
2000-04-13 02:42:50 +00:00
Jeremy Hylton 394b54d01a ord: provide better error messages 2000-04-12 21:19:47 +00:00
Guido van Rossum 3afba7644b Marc-Andre Lemburg:
Added special case to unicode(): when being passed a
Unicode object as first argument, return the object as-is.
Raises an exception when given a Unicode object *and* an
encoding name.
2000-04-11 15:38:23 +00:00
Guido van Rossum 9e896b37c7 Marc-Andre's third try at this bulk patch seems to work (except that
his copy of test_contains.py seems to be broken -- the lines he
deleted were already absent).  Checkin messages:


New Unicode support for int(), float(), complex() and long().

- new APIs PyInt_FromUnicode() and PyLong_FromUnicode()
- added support for Unicode to PyFloat_FromString()
- new encoding API PyUnicode_EncodeDecimal() which converts
  Unicode to a decimal char* string (used in the above new
  APIs)
- shortcuts for calls like int(<int object>) and float(<float obj>)
- tests for all of the above

Unicode compares and contains checks:
- comparing Unicode and non-string types now works; TypeErrors
  are masked, all other errors such as ValueError during
  Unicode coercion are passed through (note that PyUnicode_Compare
  does not implement the masking -- PyObject_Compare does this)
- contains now works for non-string types too; TypeErrors are
  masked and 0 returned; all other errors are passed through

Better testing support for the standard codecs.

Misc minor enhancements, such as an alias dbcs for the mbcs codec.

Changes:
- PyLong_FromString() now applies the same error checks as
  does PyInt_FromString(): trailing garbage is reported
  as error and not longer silently ignored. The only characters
  which may be trailing the digits are 'L' and 'l' -- these
  are still silently ignored.
- string.ato?() now directly interface to int(), long() and
  float(). The error strings are now a little different, but
  the type still remains the same. These functions are now
  ready to get declared obsolete ;-)
- PyNumber_Int() now also does a check for embedded NULL chars
  in the input string; PyNumber_Long() already did this (and
  still does)

Followed by:

Looks like I've gone a step too far there... (and test_contains.py
seem to have a bug too).

I've changed back to reporting all errors in PyUnicode_Contains()
and added a few more test cases to test_contains.py (plus corrected
the join() NameError).
2000-04-05 20:11:21 +00:00
Guido van Rossum 09095f3f61 Marc-Andre Lemburg: added new builtin functions unicode() and

2000-03-10 23:00:52 +00:00
Guido van Rossum 43713e5a28 Massive patch by Skip Montanaro to add ":name" to as many

1999-07-19 15:21:16 +00:00
Guido van Rossum 8746082175 Patch by Tim Peters:
Introduce a new builtin exception, UnboundLocalError, raised when ceval.c
tries to retrieve or delete a local name that isn't bound to a value.
Currently raises NameError, which makes this behavior a FAQ since the same
error is raised for "missing" global names too:  when the user has a global
of the same name as the unbound local, NameError makes no sense to them.
Even in the absence of shadowing, knowing whether a bogus name is local or
global is a real aid to quick understanding.

Example:

D:\src\PCbuild>type local.py
x = 42

def f():
    print x
    x = 13
    return x

f()

D:\src\PCbuild>python local.py
Traceback (innermost last):
  File "local.py", line 8, in ?
    f()
  File "local.py", line 4, in f
    print x
UnboundLocalError: x

D:\src\PCbuild>

Note that UnboundLocalError is a subclass of NameError, for compatibility
with existing class-exception code that may be trying to catch this as a
NameError.  Unfortunately, I see no way to make this wholly compatible
with -X (see comments in bltinmodule.c):  under -X, [UnboundLocalError
is an alias for NameError --GvR].

[The ceval.c patch differs slightly from the second version that Tim
submitted; I decided not to raise UnboundLocalError for DELETE_NAME,
only for DELETE_LOCAL.  DELETE_NAME is only generated at the module
level, and since at that level a NameError is raised for referencing
an undefined name, it should also be raised for deleting one.]
1999-06-22 14:47:32 +00:00
Guido van Rossum 7f85186921 # Darn! Local variable l declared but not used in abstract_issubclass(). 1999-06-17 19:12:39 +00:00
Guido van Rossum 668213d3b8 Patch by Jim Fulton (code style tweaked a bit) to support
ExtensionClasses in isinstance() and issubclass().

  - abstract instance and class protocols are used *only* in those
    cases that would generate errors before the patch.  That is, there's
    no penalty for the normal case.

  - instance protocol: an object smells like an instance if it
    has a __class__ attribute that smells like a class.

  - class protocol: an object smells like a class if it has a
    __bases__ attribute that is a tuple with elements that
    smell like classes (although not all elements may actually get
    sniffed ;).
1999-06-16 17:28:37 +00:00
Guido van Rossum 99fb7c70f4 Remove unused variable from complex_from_string() code. 1999-04-07 16:05:47 +00:00
Guido van Rossum 1195023b89 Patch by Nick and Stephanie Lockwood to implement complex() with a string
argument.  This closes TODO item 2.19.
1999-03-25 21:16:07 +00:00
Guido van Rossum 0daf022225 New builtin buffer() creates a derived read-only buffer from any
object that supports the buffer interface (e.g. strings, arrays).
1999-03-19 19:07:19 +00:00
Barry Warsaw 72b715d979 (initerrors): Make sure that the exception tuples ("base-classes" when
string-based exceptions are used) reflect the real class hierarchy,
i.e. that SystemExit derives from Exception not StandardError.
1999-02-24 00:35:43 +00:00
Guido van Rossum 124eff0225 Patch by Tim Peters to improve the range checks for range() and
xrange(), especially for platforms where int and long are different
sizes (so sys.maxint isn't actually the theoretical limit for the
length of a list, but the largest C int is -- sys.maxint is the
largest Python int, which is actually a C long).
1999-02-23 16:11:01 +00:00
Barry Warsaw 7890203f49 bltin_exc[]: EnvironmentError is not a "leaf exception", so set it's
leaf_exc flag to zero otherwise the name leaks memory.
1999-01-29 20:29:49 +00:00
Barry Warsaw fa77e09dd0 builtin_map(): A better fix for the previous leak plug (remember
PyList_Append steals a reference even if it fails).

builtin_filter(): Had the same leak problem as builtin_map().
1999-01-28 18:49:12 +00:00
Barry Warsaw 2133287c3e builtin_map(): Nailed memory leak. PyList_Append() borrows a
reference, so you have to DECREF the appended value.  This was a fun
one!
1999-01-28 04:21:35 +00:00
Barry Warsaw f988e687a1 builtin_complex(): Nailed memory leak. This one's in the instance
test for classes with a __complex__() method.  The attribute is pulled
out of the instance with PyObject_GetAttr() but this transfers
ownership and the function object was never DECREF'd.
1999-01-27 23:13:59 +00:00
Guido van Rossum e23cde2f8d Avoid overflow if possible in calculations for range(); report
unavoidable overflow as OverflowError.
1999-01-12 05:07:47 +00:00
Barry Warsaw 344864fcfb Added new builtin standard exception: NotImplementedError (its C
counterpart is PyExc_NotImplementedError).
1998-12-01 18:52:06 +00:00
Guido van Rossum df12a59305 Fix cosmetic bug in delattr docstring discovered by JvR. 1998-11-23 22:13:04 +00:00
Barry Warsaw 968f8cbace builtin_apply(): Second argument type check is relaxed to allow any sequence. 1998-10-01 15:33:12 +00:00
Barry Warsaw 98b6246c0c Several changes that Python carry on in the face of errors in the
initialization of class exceptions.  Specifically:

init_class_exc(): This function now returns an integer status of the
class exception initialization.  No fatal errors in this method now.
Also, use PySys_WriteStderr() when writing error messages.  When an
error occurs in this function, 0 is returned, but the partial creation
of the exception classes is not undone (this happens elsewhere).

Things that could trigger the fallback:

    - exceptions.py fails to be imported (due to syntax error, etc.)

    - one of the exception classes is missing (e.g. due to library
      version mismatch)

    - exception class can't be inserted into __builtin__'s dictionary

    - MemoryError instance can't be pre-allocated

    - some other PyErr_Occurred

newstdexception(): Changed the error message.  This is still a fatal
error because if the string based exceptions can't be created, we
really can't continue.

initerrors(): Be sure to xdecref the .exc field, which might be
non-NULL if class exceptions init was aborted.

_PyBuiltin_Init_2(): If class exception init fails, print a warning
message and reinstate the string based exceptions.
1998-09-14 18:51:11 +00:00
Guido van Rossum 746340d989 Should no longer surround PyOS_Readline() call with
Py_{BEGIN,END}_ALLOW_THREADS macros.  Also get rid of the declaration
for it (it's now in pythonrun.h).
1998-09-03 22:25:05 +00:00
Barry Warsaw d086a1a864 Added support for two new standard errors: EnvironmentError and
OSError.  The EnvironmentError serves primarily as the (common
implementation) base class for IOError and OSError.  OSError is used
by posixmodule.c

Also added tuple definition of EnvironmentError when using string
based exceptions.
1998-07-23 15:59:57 +00:00
Guido van Rossum fa4ac71dd6 Small changes to map() and filter():
(1) If a sequence S is shorter than len(S) indicated, don't fail --
just use the shorter size.  (I.e, len(S) is just a hint.)

(2) Implement the special case map(None, S) as list(S) -- it's faster.
1998-07-10 17:37:30 +00:00
Guido van Rossum 8ea9f4d10a Fix a stupid little bug: len() of an unsized returns -1 and leaves an
exception waiting to happen next...
1998-06-29 22:26:50 +00:00
Guido van Rossum 950ff2923a Experimental feature: add default argument to getattr(). 1998-06-29 13:38:57 +00:00
Guido van Rossum f9d9c6c5d2 Added doc strings. 1998-06-26 21:23:49 +00:00
Guido van Rossum d9b5208e90 In raw_input(prompt), make sure that str(prompt) really a string
object before using it.
1998-06-26 18:25:38 +00:00
Guido van Rossum 9396673a58 Remove a few unused locals (I love VC++ for this!). 1998-05-29 02:59:00 +00:00
Guido van Rossum 09df08a105 A bunch of functions are now properly implemented in abstract.c, and
the code here becomes much simpler.  In particular: abs(), divmod(),
pow(), int(), long(), float(), len(), tuple(), list().

Also make sure that no use of a function pointer gotten from a
tp_as_sequence or tp_as_mapping structure is made without checking it
for NULL first.

A few other cosmetic things, such as properly reindenting slice().
1998-05-22 00:51:39 +00:00
Guido van Rossum 1e162d3753 Implement round() slightly different, so that for negative ndigits no
additional errors happen in the last step.  The trick is to avoid
division by 0.1**n -- multiply by 10.0**n instead.
1998-05-09 14:42:25 +00:00
Guido van Rossum a937d14898 Fred's right -- we need PyList_SET_ITEM(). 1998-04-24 18:22:02 +00:00
Guido van Rossum 507338e5ca In-line the code in range() to set the list items; there's really no
need to call PyList_SetItem(v,i,w) when PyList_GET_ITEM(v,i)=w {sic}
will do.
1998-04-23 21:46:19 +00:00
Guido van Rossum 730806d3d9 Make new gcc -Wall happy 1998-04-10 22:27:42 +00:00
Guido van Rossum 8f74571596 Use a faster way to check for null bytes in the string argument for
int(), long(), float().
1998-03-13 21:30:14 +00:00
Guido van Rossum d6af46d4ae Need a cast when comparing type object in isinstance() 1997-12-10 05:51:47 +00:00
Guido van Rossum f5dd914196 Support type objects in isinstance().
E.g. isinstance('',types.StringType) will return true now instead of
raising a TypeError exception.  This is for JPython compatibility.
1997-12-02 19:11:45 +00:00
Guido van Rossum ee81af8977 Release interpreter lock around readline call in [raw_]input(). 1997-09-26 21:47:43 +00:00
Barry Warsaw b01a7fa5f8 initerrors(): Eliminate circular reference which was causing a small
but annoying memory leak.  This was introduced when PyExc_Exception
was added; the loop above populating the PyExc_StandardError exception
tuple started at index 1 in bltin_exc, but PyExc_Exception was added
at index 0, so PyExc_StandardError was getting inserted in itself!
How else can a tuple include itself?!

Change the loop to start at index 2.

This was a *fun* one! :-)
1997-09-18 03:44:38 +00:00
Barry Warsaw 412cdc2284 [Py_Exc]NumberError => [Py_Exc]ArithmeticError 1997-09-16 21:51:14 +00:00
Guido van Rossum 0474832d9c Introduce PyExc_Exception as the conceptual root class for all exceptions. 1997-09-16 18:43:15 +00:00
Guido van Rossum aee0bad0a5 First part of package support.
This doesn't yet support "import a.b.c" or "from a.b.c import x", but
it does recognize directories.  When importing a directory, it
initializes __path__ to a list containing the directory name, and
loads the __init__ module if found.

The (internal) find_module() and load_module() functions are
restructured so that they both also handle built-in and frozen modules
and Mac resources (and directories of course).  The imp module's
find_module() and (new) load_module() also have this functionality.
Moreover, imp unconditionally defines constants for all module types,
and has two more new functions: find_module_in_package() and
find_module_in_directory().

There's also a new API function, PyImport_ImportModuleEx(), which
takes all four __import__ arguments (name, globals, locals, fromlist).
The last three may be NULL.  This is currently the same as
PyImport_ImportModule() but in the future it will be able to do
relative dotted-path imports.

Other changes:

- bltinmodule.c: in __import__, call PyImport_ImportModuleEx().

- ceval.c: always pass the fromlist to __import__, even if it is a C
function, so PyImport_ImportModuleEx() is useful.

- getmtime.c: the function has a second argument, the FILE*, on which
it applies fstat().  According to Sjoerd this is much faster.  The
first (pathname) argument is ignored, but remains for backward
compatibility (so the Mac version still works without changes).

By cleverly combining the new imp functionality, the full support for
dotted names in Python (mini.py, not checked in) is now about 7K,
lavishly commented (vs. 14K for ni plus 11K for ihooks, also lavishly
commented).

Good night!
1997-09-05 07:33:22 +00:00
Barry Warsaw 757af0e7bb Removed obsolete exception PyExc_AccessError.
Added PyErr_MemoryErrorInst to hold the pre-instantiated instance when
using class based exceptions.

Simplified the creation of all built-in exceptions, both class based
and string based.  Actually, for class based exceptions, the string
ones are still created just in case there's a problem creating the
class based ones (so you still get *some* exception handling!).  Now
the init and fini functions run through a list of structure elements,
creating the strings (and optionally classes) for every entry.

initerrors(): the new base class exceptions StandardError,
LookupError, and NumberError are initialized when using string
exceptions, to tuples containing the list of derived string
exceptions.  This GvR trick enables forward compatibility!  One bit of
nastiness is that the C code has to know the inheritance tree embodied
in exceptions.py.

Added the two phase init and fini functions.
1997-08-29 22:13:51 +00:00
Barry Warsaw cde8b1ba0c Two new built-in functions: issubclass() and isinstance(). Both take
classes as their second arguments.  The former takes a class as the
first argument and returns true iff first is second, or is a subclass
of second.

The latter takes any object as the first argument and returns true iff
first is an instance of the second, or any subclass of second.

Also, change all occurances of pointer compares against
PyExc_IndexError with PyErr_ExceptionMatches() calls.
1997-08-22 21:14:38 +00:00
Guido van Rossum 25ce566661 The last of the mass checkins for separate (sub)interpreters.
