Guido van Rossum 6c2f0c73a1 When returning an error from jcompile() (which is passed through by
PyNode_Compile()), make sure that an exception is actually set --
otherwise someone stomped on our error.  [2.0 checkin of this fix.]

Jack Jansen cc22fbe3db Changed H specifier to mean "bitfield", i.e. any value from
-32768..65535 is acceptable. Added B specifier (with values from
-128..255). No L added (which would have completed the set) because l
already accepts any value (and the letter L is taken for quadwords).

Guido van Rossum 413407f103 Add a test that Py_IsInitialized() in Py_InitModule4(). See
python-dev discussion.

This should catch future version incompatibilities on Windows.  Alas,
this doesn't help for 1.5 vs. 1.6; but it will help for 1.6 vs. 2.0.

Marc-André Lemburg bff879cabb This patch finalizes the move from UTF-8 to a default encoding in
the Python Unicode implementation.

The internal buffer used for implementing the buffer protocol
is renamed to defenc to make this change visible. It now holds the
default encoded version of the Unicode object and is calculated
on demand (NULL otherwise).

Since the default encoding defaults to ASCII, this will mean that
Unicode objects which hold non-ASCII characters will no longer
work on C APIs using the "s" or "t" parser markers. C APIs must now
explicitly provide Unicode support via the "u", "U" or "es"/"es#"
parser markers in order to work with non-ASCII Unicode strings.

(Note: this patch will also have to be applied to the 1.6 branch
 of the CVS tree.)

Thomas Wouters 1e0c2f4bee Create a new section of pyport.h to hold all external function declarations
for systems that are missing those declarations from system include files.
Start by moving a pointy-haired ones from their previous locations to the
new section.

(The gethostname() one, for instance, breaks on several systems, because
some define it as (char *, size_t) and some as (char *, int).)

I purposely decided not to include the summary of used #defines like Tim did
in the first section of pyport.h. In my opinion, the number of #defines
likedly to be used by this section would make such an overview unwieldy. I
would suggest documenting the non-obvious ones, though.

Tim Peters 8315ea5790 Included assert.h in Python.h -- it's absurd that this basic tool of
good C practice hasn't been available to everything all along.
Added Py_SAFE_DOWNCAST(VALUE, WIDE, NARROW) macro to pyport.h; this
just casts VALUE from type WIDE to type NARROW, but assert-fails if
Py_DEBUG is defined and info is lost due to casting.
Replaced a line in Fredrik's fix to marshal.c to use the new macro.

Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Fred Drake 615ae55eca Trent Mick <trentm@activestate.com>:
The common technique for printing out a pointer has been to cast to a long
and use the "%lx" printf modifier. This is incorrect on Win64 where casting
to a long truncates the pointer. The "%p" formatter should be used instead.

The problem as stated by Tim:
> Unfortunately, the C committee refused to define what %p conversion "looks
> like" -- they explicitly allowed it to be implementation-defined. Older
> versions of Microsoft C even stuck a colon in the middle of the address (in
> the days of segment+offset addressing)!

The result is that the hex value of a pointer will maybe/maybe not have a 0x
prepended to it.


Notes on the patch:

There are two main classes of changes:
- in the various repr() functions that print out pointers
- debugging printf's in the various thread_*.h files (these are why the
patch is large)


Closes SourceForge patch #100505.

Fred Drake 4c82b2366f Trent Mick <trentm@activestate.com>:
This patch fixes possible overflow in the use of
PyOS_GetLastModificationTime in getmtime.c and Python/import.c.

Currently PyOS_GetLastModificationTime returns a C long. This can
overflow on Win64 where sizeof(time_t) > sizeof(long). Besides it
should logically return a time_t anyway (this patch changes this).

As well, import.c uses PyOS_GetLastModificationTime for .pyc
timestamping.  There has been recent discussion about the .pyc header
format on python-dev.  This patch adds oveflow checking to import.c so
that an exception will be raised if the modification time
overflows. There are a few other minor 64-bit readiness changes made
to the module as well:

- size_t instead of int or long for function-local buffer and string
length variables

- one buffer overflow check was added (raises an exception on possible
overflow, this overflow chance exists on 32-bit platforms as well), no
other possible buffer overflows existed (from my analysis anyway)

Closes SourceForge patch #100509.

Guido van Rossum 5e08cb8e50 Vladimir Marangozov:
This patch fixes a problem on AIX with the signed int case code in
getargs.c, after Trent Mick's intervention about MIN/MAX overflow
checks. The AIX compiler/optimizer generates bogus code with the
default flags "-g -O" causing test_builtin to fail: int("10", 16) <>
16L. Swapping the two checks in the signed int code makes the problem
go away.

Also, make the error messages fit in 80 char lines in the
source.

Guido van Rossum 98626cd7ac Urmpf. Quality control on this patch lapsed a bit. :-(
The depth field was never decremented inside w_object(), and it was
never initialized in PyMarshal_WriteObjectToFile().

This caused imports from .pyc files to fil mysteriously when the .pyc
file was written by the broken code -- w_object() would bail out
early, but PyMarshal_WriteObjectToFile() doesn't check the error or
return an error code, and apparently the marshalling code doesn't call
PyErr_Check() either.  (That's a separate patch if I feel like it.)
2000-06-28 23:24:19 +00:00
Guido van Rossum 582acece2e Trent Mick's Win64 changes: size_t vs. int or long; also some overflow

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.

Fred Drake 6da0b9148c Michael Hudson <mwh21@cam.ac.uk>:
As I really do not have anything better to do at the moment, I have written
a patch to Python/marshal.c that prevents Python dumping core when trying
to marshal stack bustingly deep (or recursive) data structure.

It just throws an exception; even slightly clever handling of recursive
data is what pickle is for...

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().

Py_Finalize(): Don't call _PyBuiltin_Fini_1().  Instead call
fini_exceptions() but move this to before the thread state is
cleared.

Guido van Rossum 706262bde0 Fast NonRecursiveMutex support by Yakov Markovitch, markovitch@iso.ru,
who wrote:

Here's the new version of thread_nt.h.  More particular, there is a
new version of thread lock that uses kernel object (e.g. semaphore)
only in case of contention; in other case it simply uses interlocked
functions, which are faster by the order of magnitude.  It doesn't
make much difference without threads present, but as soon as thread
machinery initialised and (mostly) the interpreter global lock is on,
difference becomes tremendous.  I've included a small script, which
initialises threads and launches pystone.  With original thread_nt.h,
Pystone results with initialised threads are twofold worse then w/o
threads.  With the new version, only 10% worse.  I have used this
patch for about 6 months (with threaded and non-threaded
applications).  It works remarkably well (though I'd desperately
prefer Python was free-threaded; I hope, it will soon).

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.

saboteur(a=1, **d)

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).

* Changes to a recent patch by Chris Tismer to errors.c.  Chris' patch

from errno - but errno and FormatMessage use a different numbering scheme.
The main reason the patch looked OK was that ENOFILE==ERROR_FILE_NOT_FOUND -
but that is about the only shared error code :-).  The MS CRT docs tell you
to use _sys_errlist()/_sys_nerr.  My patch does also this, and adds a very
similar function specifically for win32 error codes.

Guido van Rossum 933c91ebcf Vladimir Marangozov fixes an AIX-specific problem, writing:
"""
Following up Robin Dunn's troubles with freeze, here's a patch that
fixes an oddity regarding the import logic of shared modules on AIX.

Symbol resolution of shared modules is now handled properly for the cases
when the python library is linked to a binary with an arbitrary name.
This includes the standard python[version] executable, but also applications
that are embedding the python core (i.e. linked with libpython[version].a,
the latter being static or shared).

1999-07-08 17:26:56 +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.]

Guido van Rossum 1d5ad90c1c CRITICAL PATCH!
We occasionally received reports from people getting "invalid tstate"
crashes (this is a fatal error in PyThreadState_Delete()).  Finally
several people were able to reproduce it reliably and Tim Peters
discovered that there is a race condition when multiple threads are
calling this function without holding the global interpreter lock (the
function may be called without holding that).

Solved the race condition by adding a lock around the mutating uses of
interp->tstate_head.  Tim and Jonathan Giddy have run tests that make
it likely that this fixes the crashes -- although Tim hasn't heard
from the person who reported the original problem.

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 ;).
