Tim Peters 5de9842b34 Repair widespread misuse of _PyString_Resize. Since it's clear people
don't understand how this function works, also beefed up the docs.  The
most common usage error is of this form (often spread out across gotos):

	if (_PyString_Resize(&s, n) < 0) {
		Py_DECREF(s);
		s = NULL;
		goto outtahere;
	}

The error is that if _PyString_Resize runs out of memory, it automatically
decrefs the input string object s (which also deallocates it, since its
refcount must be 1 upon entry), and sets s to NULL.  So if the "if"
branch ever triggers, it's an error to call Py_DECREF(s):  s is already
NULL!  A correct way to write the above is the simpler (and intended)

	if (_PyString_Resize(&s, n) < 0)
		goto outtahere;

Bugfix candidate.

Fred Drake f495ef7466 Warn people away from PyModule_GetDict(), but not too strongly.
(The real issue is whether modules can benefit from an alternate
implementation strategy rather than using a dictionary.  We should migrate
away from direct dictionary manipulation to allow more room for Jeremy to
flex the implementation with changes in globals lookup.)

2002-04-04 04:10:36 +00:00
Fred Drake 7bf9715a8b Introduce two new flag bits that can be set in a PyMethodDef method
descriptor, as used for the tp_methods slot of a type.  These new flag
bits are both optional, and mutually exclusive.  Most methods will not
use either.  These flags are used to create special method types which
exist in the same namespace as normal methods without having to use
tedious construction code to insert the new special method objects in
the type's tp_dict after PyType_Ready() has been called.

If METH_CLASS is specified, the method will represent a class method
like that returned by the classmethod() built-in.

If METH_STATIC is specified, the method will represent a static method
like that returned by the staticmethod() built-in.

These flags may not be used in the PyMethodDef table for modules since
these special method types are not meaningful in that case; a
ValueError will be raised if these flags are found in that context.

Fred Drake c37b65ee10 Clean up some markup cruft. A number of the macros that take no
parameters (like \UNIX) are commonly entered using an empty group to
separate the markup from a following inter-word space; this is not
needed when the next character is punctuation, or the markup is the
last thing in the enclosing group.  These cases were marked
inconsistently; the empty group is now *only* used when needed.

Tim Peters 1fc240e851 Generalize dictionary() to accept a sequence of 2-sequences. At the
outer level, the iterator protocol is used for memory-efficiency (the
outer sequence may be very large if fully materialized); at the inner
level, PySequence_Fast() is used for time-efficiency (these should
always be sequences of length 2).

dictobject.c, new functions PyDict_{Merge,Update}FromSeq2.  These are
wholly analogous to PyDict_{Merge,Update}, but process a sequence-of-2-
sequences argument instead of a mapping object.  For now, I left these
functions file static, so no corresponding doc changes.  It's tempting
to change dict.update() to allow a sequence-of-2-seqs argument too.

Also changed the name of dictionary's keyword argument from "mapping"
to "x".  Got a better name?  "mapping_or_sequence_of_pairs" isn't
attractive, although more so than "mosop" <wink>.

abstract.h, abstract.tex:  Added new PySequence_Fast_GET_SIZE function,
much faster than going thru the all-purpose PySequence_Size.

libfuncs.tex:
- Document dictionary().
- Fiddle tuple() and list() to admit that their argument is optional.
- The long-winded repetitions of "a sequence, a container that supports
  iteration, or an iterator object" is getting to be a PITA.  Many
  months ago I suggested factoring this out into "iterable object",
  where the definition of that could include being explicit about
  generators too (as is, I'm not sure a reader outside of PythonLabs
  could guess that "an iterator object" includes a generator call).
- Please check my curly braces -- I'm going blind <0.9 wink>.

abstract.c, PySequence_Tuple():  When PyObject_GetIter() fails, leave
its error msg alone now (the msg it produces has improved since
PySequence_Tuple was generalized to accept iterable objects, and
PySequence_Tuple was also stomping on the msg in cases it shouldn't
have even before PyObject_GetIter grew a better msg).

Marc-André Lemburg 2d9204199f This patch changes the way the string .encode() method works slightly
and introduces a new method .decode().

The major change is that strg.encode() will no longer try to convert
Unicode returns from the codec into a string, but instead pass along
the Unicode object as-is. The same is now true for all other codec
return types. The underlying C APIs were changed accordingly.

Note that even though this does have the potential of breaking
existing code, the chances are low since conversion from Unicode
previously took place using the default encoding which is normally
set to ASCII rendering this auto-conversion mechanism useless for
most Unicode encodings.

The good news is that you can now use .encode() and .decode() with
much greater ease and that the door was opened for better accessibility
of the builtin codecs.

As demonstration of the new feature, the patch includes a few new
codecs which allow string to string encoding and decoding (rot13,
hex, zip, uu, base64).

Marc-André Lemburg 8155e0e541 This patch originated from an idea by Martin v. Loewis who submitted a
patch for sharing single character Unicode objects.

Martin's patch had to be reworked in a number of ways to take Unicode
resizing into consideration as well. Here's what the updated patch
implements:

* Single character Unicode strings in the Latin-1 range are shared
  (not only ASCII chars as in Martin's original patch).

* The ASCII and Latin-1 codecs make use of this optimization,
  providing a noticable speedup for single character strings. Most
  Unicode methods can use the optimization as well (by virtue
  of using PyUnicode_FromUnicode()).

* Some code cleanup was done (replacing memcpy with Py_UNICODE_COPY)

* The PyUnicode_Resize() can now also handle the case of resizing
  unicode_empty which previously resulted in an error.

* Modified the internal API _PyUnicode_Resize() and
  the public PyUnicode_Resize() API to handle references to
  shared objects correctly. The _PyUnicode_Resize() signature
  changed due to this.

* Callers of PyUnicode_FromUnicode() may now only modify the Unicode
  object contents of the returned object in case they called the API
  with NULL as content template.

Note that even though this patch passes the regression tests, there
may still be subtle bugs in the sharing code.

Fred Drake e28d8aef2d Be more clear about the specific rules for supporting the cyclic GC in an
extension object.  Also included an example showing exactly what needs to
be done and nothing else.

This closes SF bug #228591.
2001-03-22 16:30:17 +00:00
Fred Drake c392b570db Integrated an expanded version of some text from Neil Schemenauer about
supporting cyclic garbage collection.  (This is not all of it, but I'm
taking a break!)

Also fixed some markup nits.
2001-03-21 22:15:01 +00:00
Fred Drake 83e01bf6c8 Finally fill in the documentation for the PyDict_Next() function. It is

Fred Drake 6b3f3f2861 In the first discussion showing how to handle exceptions from C, make the
Python equivalent actually equivalent to the C code.  Also, in the C code,
place the "goto" statements on a line by themselves for better visibility
of statements that affect control flow.

Fred Drake 8902442e2f Added exception to the rule that the buffer returned by PyString_AsString()
and PyString_AsStringAndSize() for strings that were just created using
PyString_FromStringAndSize(NULL, n).

Added warning about passing NULL to the concrete object functions; many of
them use the appropriate Py<Type>_Check() test, but do not check for NULL.

Fred Drake 89fb035248 For PyErr_Format(), note that the exception parameter can be a string or

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.

Fix typo in a C code example:  KeyError is spelled PyExc_KeyError in C; the

Some index entries.

On function signatures, always use parameter names.  Make return types match
what's in the header files.  When the return type is a pointer, always omit
the space between te type name and the "*"; leaving it in results in

	type * func(..)

and having two spaces there just looks terrible.

Fred Drake 6659c30b67 Convert LaTeX support to create a new class of documents. HTML generation
now requires LaTeX2HTML 98.1p1 or newer (& and is still in progress).

This means that doing things to change the formatting of the manuals (at the

than in each document file.

Fred Drake e058b4f124 Lots of nitty-gritty stuff:
Use \emph{} when referring to title of any of the Python manuals, like is
done in the other manuals.

In some places, use \emph{} or \dfn{} instead of ``...''.

Use \samp{} instead of \code{} when marking identifier prefixes.

Use logical markup wherever it made sense.

Fixed a bunch of typos.

In several places, use "---" instead of "--" to get the emdash.

Start sentences with capital letters and end them with periods, as needed.

"it's" --> "its" in many places:  "it's" it *always* a contraction of "it is",
and "its" should always be used for the possessive.

"don't" --> "doesn't"

"should discards any" --> "should discard any"

In C function descriptions, use \var{} to mark parameters in the running
text instead of \code{}.  This matches usage in the other manauls better,
and is more consistent with the formatting of the function signatures.
Lots of little changes to implement this.

Lots of fixups needed due to appearant heavy cut-&-paste in the orignal
document.

Mention that the exception objects may be either classes or strings,
depending on the use of -X; they were unequivocally stated to be strings
in the section "Standard Exceptions".

"mkvalue()" --> "Py_BuildValue()"

Description of PyNumber_Power() indicates that the third value is option,
but not how to indicate that it was omitted.  Clarified.

Explain the behavior of PyString_FromStringAndSize() if the buffer is NULL.

Explain the Py_complex structure a little (tell what it's used for) and use
a {verbatim} environment for the structure definition itself.

Fix explanation of PyFile_SoftSpace().

Update the example version string to 1.5.
