a96f1a3c08 Refactor: Remove some code that was obsoleted when this module was
changed to use universal newlines.

           Remove all imports from the compile() function; these are
           now done at the top of the module ("Python normal form"),
           and define a helper based on the platform instead of
           testing the platform in the compile() function.

5b09eeea89 Clarify that even though some of the relevant specifications define the
order in which form variables should be encoded in a request, a CGI script
should not rely on that since a client may not conform to those specs, or
they may not be relevant to the request.
Closes SF bug #596866.

d9c9151a53 Now that __init__ transforms set elements, we know that all of the
elements are hashable, so we can use dict.update() or dict.copy()
for a C speed Set.copy().

80d21af614 Sped ._update() method by factoring try/except out of the inner loop. 2002-08-21 04:12:03 +00:00
Guido van Rossum
9f87293bf5 Ouch. The test suite *really* needs work!!!!! There were several
superficial errors and one deep one that aren't currently caught.  I'm
headed for bed after this checkin.

- Fixed several typos introduced by Raymond Hettinger (through
  cut-n-paste from my template): it's _as_temporarily_immutable, not
  _as_temporary_immutable, and moreover when the element is added, we
  should use _as_immutable.

- Made the seq argument to ImmutableSet.__init__ optional, so we can
  write ImmutableSet() to create an immutable empty set.

- Rename the seq argument to Set and ImmutableSet to iterable.

- Add a Set.__hash__ method that raises a TypeError.  We inherit a
  default __hash__ implementation from object, and we don't want that.
  We can then catch this in update(), so that
  e.g. s.update([Set([1])]) will transform the Set([1]) to
  ImmutableSet([1]).

- Added the dance to catch TypeError and try _as_immutable in the
  constructors too (by calling _update()).  This is needed so that
  Set([Set([1])]) is correctly interpreted as
  Set([ImmutableSet([1])]).  (I was puzzled by a side effect of this
  and the inherited __hash__ when comparing two sets of sets while
  testing different powerset implementations: the Set element passed
  to a Set constructor wasn't transformed to an ImmutableSet, and then
  the dictionary didn't believe the Set found in one dict it was the
  same as ImmutableSet in the other, because the hashes were
  different.)

- Refactored Set.update() and both __init__() methods; moved the body
  of update() into BaseSet as _update(), and call this from __init__()
  and update().

- Changed the NotImplementedError in BaseSet.__init__ to TypeError,
  both for consistency with basestring() and because we have to use
  TypeError when denying Set.__hash__.  Together those provide
  sufficient evidence that an unimplemented method needs to raise
  TypeError.

5033b36c44 Move __init__ from BaseSet into Set and ImmutableSet. This causes a
tiny amount of code duplication, but makes it possible to give BaseSet
an __init__ that raises an exception.

0d2d87d202 long_format(), long_lshift(): Someone on c.l.py is trying to boost
SHIFT and MASK, and widen digit.  One problem is that code of the form

    digit << small_integer

implicitly assumes that the result fits in an int or unsigned int
(platform-dependent, but "int sized" in any case), since digit is
promoted "just" to int or unsigned via the usual integer promotions.
But if digit is typedef'ed as unsigned int, this loses information.
The cure for this is just to cast digit to twodigits first.

Barry Warsaw
f36d804b3b get_content_type(), get_content_maintype(), get_content_subtype(): RFC
2045, section 5.2 states that if the Content-Type: header is
syntactically invalid, the default type should be text/plain.
Implement minimal sanity checking of the header -- it must have
exactly one slash in it.  This closes SF patch #597593 by Skip, but in
a different way.

Note that these methods used to raise ValueError for invalid ctypes,
but now they won't.

45ec02aed1 SF patch 576101, by Oren Tirosh: alternative implementation of
interning.  I modified Oren's patch significantly, but the basic idea
and most of the implementation is unchanged.  Interned strings created
with PyString_InternInPlace() are now mortal, and you must keep a
reference to the resulting string around; use the new function
PyString_InternImmortal() to create immortal interned strings.

d8dbf847b6 Add a warning comment to the LOAD_GLOBAL inline code. 2002-08-19 21:17:53 +00:00
Guido van Rossum
3a4dfc87e6 Another ugly inlining hack, expanding the two PyDict_GetItem() calls
in LOAD_GLOBAL.  Besides saving a C function call, it saves checks
whether f_globals and f_builtins are dicts, and extracting and testing
the string object's hash code is done only once.  We bail out of the
inlining if the name is not exactly a string, or when its hash is -1;
because of interning, neither should ever happen.  I believe interning
guarantees that the hash code is set, and I believe that the 'names'
tuple of a code object always contains interned strings, but I'm not
assuming that -- I'm simply testing hash != -1.

On my home machine, this makes a pystone variant with new-style
classes and slots run at the same speed as classic pystone!  (With
new-style classes but without slots, it is still a lot slower.)

e3a8e7ed1d Call me anal, but there was a particular phrase that was speading to
comments everywhere that bugged me: /* Foo is inlined */ instead of
/* Inline Foo */.  Somehow the "is inlined" phrase always confused me
for half a second (thinking, "No it isn't" until I added the missing
"here").  The new phrase is hopefully unambiguous.

c588e9041a Simple but important optimization for descr_check(): instead of the
expensive and overly general PyObject_IsInstance(), call
PyObject_TypeCheck() which is a macro that often avoids a call, and if
it does make a call, calls the much more efficient PyType_IsSubtype().
This saved 6% on a benchmark for slot lookups.

58ba80a6a6 Refuse to run if the last bit of the destination path contains a # character.
This is a silly workaround for a rather serious bug in MacOSX: if you take
a long filename and convert it to an FSSpec the fsspec gets a magic
cooky (containing a #, indeed). If you then massage the extension of this
fsspec and convert back to a pathname you may end up referring to the
same file. This could destroy your sourcefile. The problem only occcurs
in MacPython-OS9, not MacPython-OSX (I think).

Closes bug #505562.
