Guido van Rossum 40552d0857 Gack. The module doc string is too long for VC++ 5.0.
However two string literals concatenated are fine!
Hope this doesn't break other platforms.

Barry Warsaw 97d951533e PyErr_SetFromErrnoWithFilename(): New function which supports setting
an exception from errno, with a supplied filename (primarily used by
IOError and OSError).  If class exceptions are used then the exception
is instantiated with a 3-tuple: (errno, strerror, filename).  For
backwards compatibility reasons, if string exceptions are used,
filename is ignored.

PyErr_SetFromErrno(): Implement in terms of
PyErr_SetFromErrnoWithFilename().

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.

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.

Guido van Rossum e32d1537f0 Sigh. The hack to enable special treatment for errno on SGI machines
must be enabled here, otherwise the errno we set on overflows is not
the errno that's being read by compile.c.  Wonder how many other files
that do their own "#include config.h" need this too :-(

(Because of the structure of autoconf, it's not so simple to get this
into config.h...)

Guido van Rossum a45cb45965 When unmarshalling, add test for negative lengths on strings, tuples

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().

Guido van Rossum adf0e437cb Trivial little change: when setting a member to an object, hold the
old value in a temporary and XDECREF it only after then new value has
been set.  This prevents the (unlikely) case where the destructor of
the member uses the containing object -- it would find it in an
undefined state.

Guido van Rossum 9c0afe5dc7 Fix a curious bug: statements like "import sys.time" would succeed,
because the path through the code would notice that sys.__path__ did
not exist and it would fall back to the default path (builtins +
sys.path) instead of failing).  No longer.

Subject: getargs bug in 1.2 and 1.3 BETA

We have found a bug in the part of the getargs code that we added
and submitted, and which was incorporated into 1.1.

The parsing of "O?" format specifiers is not handled correctly;
there is no "else" for the "if" and therefore it can never fail.
What's worse, the advancing of the varargs pointer is not
handled properly, so from then on it is out of sync, wreaking
all sorts of havoc. (If it had failed properly, then the out-of-sync
varargs would not have been an issue.)

Below is the context diff for the change.

Note that I have made a few stylistic changes beyond adding the
else case, namely:

1) Making the "O" case follow the convention established by the other
format specifiers of getting all their vararg arguments before
performing the test, rather than getting some before and some after
the test passes.

2) Making the logic of the tests parallel, so the "if" part indicates
that the format is accepted and the "else" part indicates that the
format has failed. They were inconsistent with each other and with the
the other format specifiers.

Guido van Rossum 859b16c847 In debug mode on MS Windows, DLLs are called foo_d.pyd or foo_d.dll. 1998-05-15 20:22:08 +00:00
Guido van Rossum 532246ef55 Improved version of patch for HPUX from David Arnold. 1998-05-14 21:01:27 +00:00
Guido van Rossum 09cae1f8cd New APIs for embedding applications that want to add their own entries
to the table of built-in modules.  This should normally be called
*before* Py_Initialize().  When the malloc() or realloc() call fails,
-1 is returned and the existing table is unchanged.

After a similar function by Just van Rossum.

Guido van Rossum 234e260d5e Since PyDict_GetItem() can't raise an exception any more, there's no
need to call PyErr_Clear() when it returns NULL.

Guido van Rossum a890e68807 New APIs to write to sys.stdout or sys.stderr using a printf-like interface.
Adapted from code submitted by Just van Rossum.

   PySys_WriteStdout(format, ...)
   PySys_WriteStderr(format, ...)

      The first function writes to sys.stdout; the second to sys.stderr.  When
      there is a problem, they write to the real (C level) stdout or stderr;
      no exceptions are raised (but a pending exception may be cleared when a
      new exception is caught).

      Both take a printf-style format string as their first argument followed
      by a variable length argument list determined by the format string.

      *** WARNING ***

      The format should limit the total size of the formatted output string to
      1000 bytes.  In particular, this means that no unrestricted "%s" formats
      should occur; these should be limited using "%.<N>s where <N> is a
      decimal number calculated so that <N> plus the maximum size of other
      formatted text does not exceed 1000 bytes.  Also watch out for "%f",
      which can print hundreds of digits for very large numbers.

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.

will do.
