This is meant to be a model for how other functions of this ilk (max,
filter, etc) can be generalized similarly. Feel encouraged to grab your
favorite and convert it!
Note some cute consequences:
list(file) == file.readlines() == list(file.xreadlines())
list(dict) == dict.keys()
list(dict.iteritems()) = dict.items()
list(xrange(i, j, k)) == range(i, j, k)
The new test case demonstrates the bug. Be more careful in
symtable_resolve_free() to add a var to cells or frees only if it
won't be added under some other rule.
XXX Add new assertion that will catch this bug.

Added assignment tests for the ordered_attributes and specified_attributes
values, similar to the checks for the returns_unicode attribute.
Obviously bad regexps, spotted by Jeffery Collins.
HELP! I can't run this on Windows, and the module test() function
probably doesn't work on anyone's box. Could a Unixoid please write
an at least minimal working test and add it to the std test suite?
new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER
new C API PyObject_GetIter(), calls tp_iter

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

I know some people don't like this -- if it's really controversial,
I'll take it out again. (If it's only Alex Martelli who doesn't like
it, that doesn't count as "real controversial" though. :-)
That's why this is a separate checkin from the iterators stuff I'm
about to check in next.
Weak*Dictionary.update(): No longer create a temporary list to hold the
things that will be stuffed into the underlying dictionary. This had
been done so that if any of the objects used as the weakly-held value
was not weakly-referencable, no updates would take place (TypeError
would be raised). With this change, TypeError will still be raised
but a partial update could occur. This is more like other .update()
implementations.
Thoughout, use of the name "ref" as a local variable has been removed. The
original use of the name occurred when the function to create a weak
reference was called "new"; the overloaded use of the name could be
confusing for someone reading the code. "ref" used as a variable name
has been replaced with "wr" (for 'weak reference').
The changes cause compilation failures in any file in the Python
installation lib directory to cause the install to fail. It looks
like compileall.py intended to behave this way, but a change to
py_compile.py and a separate bug defeated it.
Fixes SF bug #412436
This change affects the test suite, which contains several files that
contain intentional errors. The solution is to extend compileall.py
with the ability to skip compilation of selected files.
NB compileall.py is changed so that compile_dir() returns success only
if all recursive calls to compile_dir() also check success.

This used to be the behavior in 1.5.2 and before, but a patch to avoid
making two stat() calls accidentally broke this in 2.0.
Moshe, this would be a good one for 2.0.1 too!
its first return statement returns a single value while its caller
always expects it to return a tuple of two items. Fix this by
returning (s, 0) instead.
This won't make the locale test on Irix succeed, but now it will fail
because of a bug in the platform's en_US locale rather than because of
a bug in the locale module.
than from module pickletester. Using the latter turned out to cause
the test to break when invoked as "import test.test_pickle" or "import
test.autotest".
cut-and-paste copy of the seek() method on the _Subfile class, but it
didn't make one bit of sense: it sets self.pos, which is not used in
this class or its subclasses, and it uses self.start and self.stop,
which aren't defined on this class or its subclasses. This is purely
my own fault -- I added this in rev 1.4 and apparently never tried to
use it. Since it's not documented, and of very questionable use given
that there's no tell(), I'm ripping it out.
This resolves SF bug 416199 by Andrew Dalke: mailbox.py seek problems.
ZipFile.close() method that should be part of the preceding 'if'
block. On some platforms (Mark noticed this on FreeBSD 4.2) doing a
flush() on a file open for reading is not allowed.
now raises NameError instead of UnboundLocalError, because the var in
question is definitely not local. (This affects test_scope.py)
Also update the recent fix by Ping using get_func_name(). Replace
tests of get_func_name() return value with call to get_func_desc() to
match all the other uses.
Make synopsis() load modules as '__temp__' so they don't clobber anything.
Change "constants" section to "data" section.
Don't show __builtins__ or __doc__ in "data" section.
For Bob Weiner: don't boldface text in Emacs shells or dumb terminals.
Remove Helper.__repr__ (it really belongs in site.py, and should be guarded by a check for len(inspect.stack) <= 2).
fixes bug #414940, and redoes the fix for #129417 in a different way.
It also fixes a number of other problems with locale-specific formatting:
If there is leading or trailing spaces, then no grouping should be applied
in the spaces, and the total length of the string should not be changed
due to grouping.
Also added test case which works only if the en_US locale is available.
value for the 'using' parameter of the get() function

instead of a short name, examine the available
controllers to see if we can synthesize one based on a
pre-registered controller that shares the same base
name.
get(): If the user specifies a browser we don't know about, use
_synthesize() to attempt to create a usable controller.
Some small adjustments were needed in some of the browser classes to
support this.
Always emit a SET_LINENO 0 at the beginning of the module. The
builtin compiler does this, and it's much easier to compare bytecode
generated by the two compilers if they both do.
Move the SET_LINENO inside the FOR_LOOP block for list
comprehensions. Also for compat. with builtin compiler.
Fix annoying bugs in flow graph layout code. In some cases the
implicit control transfers weren't honored. In other cases,
JUMP_FORWARD instructions jumped backwards.
Remove unused arg from nextBlock().
pycodegen.py
Add optional force kwarg to set_lineno() that will emit a
SET_LINENO even if it is the same as the previous lineno.
Use explicit LOAD_FAST and STORE_FAST to access list comp implicit
variables. (The symbol table doesn't know about them.)
"%#x" % 0
blew up, at heart because C sprintf supplies a base marker if and only if
the value is not 0. I then fixed that, by tolerating C's inconsistency
when it does %#x, and taking away that *Python* produced 0x0 when
formatting 0L (the "long" flavor of 0) under %#x itself. But after talking
with Guido, we agreed it would be better to supply 0x for the short int
case too, despite that it's inconsistent with C, because C is inconsistent
with itself and with Python's hex(0) (plus, while "%#x" % 0 didn't work
before, "%#x" % 0L *did*, and returned "0x0"). Similarly for %#X conversion.
Fix so that docother() doesn't blow up.
Eliminate man() function since doc() and man() did nearly the same thing.
Various other code cleanup and refactoring to reduce duplication.
Simplify and rewrite freshimport() so modules are always up to date,
even within packages (where reload() doesn't work).
Add finalization callback to the server (so that if the server fails to
start for some reason, the main thread isn't left hanging).
http://sourceforge.net/tracker/index.php?func=detail&aid=415514&group_id=5470&atid=105470
For short ints, Python defers to the platform C library to figure out what
%#x should do. The code asserted that the platform C returned a string
beginning with "0x". However, that's not true when-- and only when --the
*value* being formatted is 0. Changed the code to live with C's inconsistency
here. In the meantime, the problem does not arise if you format a long 0 (0L)
instead. However, that's because the code *we* wrote to do %#x conversions on
longs produces a leading "0x" regardless of value. That's probably wrong too:
we should drop leading "0x", for consistency with C, when (& only when) formatting
0L. So I changed the long formatting code to do that too.
catch IOError as well as OverflowError. I found that on Tru64 Unix
this was raised; probably because the OS (or libc) doesn't support
large files but the architecture is 64 bits!
Avoid ever using popen on Windows, since it's broken there.
Factor out the business of getting the summary line into splitdoc().
Use the modulename() routine in inspect.
Show all members of modules and classes rather than filtering on leading '_'.
Small typo and formtating fixes.
Don't show warnings when running "pydoc -k".
pickle.py
The code implicitly assumed that all ints fit in 4 bytes, causing all
sorts of mischief (from nonsense results to corrupted pickles).
Repaired that.
marshal.c
The int marshaling code assumed that right shifts of signed longs
sign-extend. Repaired that.
bugs on sizeof(long)==8 machines. pickle.py has no idea what it's
doing with very large ints, and variously gets things right by accident,
computes nonsense, or generates corrupt pickles. cPickle fails on
cases 2**31 <= i < 2**32: since it *thinks* those are 4-byte ints
(the "high 4 bytes" are all zeroes), it stores them in the (signed!) BININT
format, so they get unpickled as negative values.
integers, but the std tests don't exercise most of them. Repair that.
CAUTION: I expect this to fail on boxes with sizeof(long)==8, in the
part of test_cpickle (but not test_pickle) trying to do a binary mode
(not text mode) load of the embedded BINDATA pickle string. Once that
hypothesized failure is confirmed, I'll fix cPickle.c.
Even though relative redirects are illegal, they are common
urllib treated every relative redirect as though it was to http,
even if the original was https://
As long as we're compensating for server bugs, might as well do
it properly.
Add mangling support
Add get_children() and add_child() methods to Scope
Skip nodes when If test is a false constant
Add test code that checks results against symtable module
Fix com_NEWLINE() so that is accepts arguments, which occurs for lines like:
stmt; # note trailing semicolon
Add XXX about checking for assignment to list comps
http://groups.yahoo.com/group/medusa/message/333
It's clear that Medusa should not be checking for an empty buffer
via "buf is ''". The patch merely changes "is" to "==". However,
there's a mystery here all the same: Python attempts to store null
strings uniquely, so it's unclear why "buf is ''" ever returned
false when buf actually was empty. *Some* string operations produce
non-unique null strings, e.g.
>>> "abc"*0 is "abc"*0
0
>>>
but they're rare, and I don't see any such operations in asynchat.
add a self-test using doctest. Results:
- The docstring needs to be a raw string because it uses \"...\".
- The oreo example was broken: the Set-Cookie output doesn't add
quotes around "doublestuff".
- I had to change the example that prints the class of a Cookie.Cookie
instance to avoid incorporating an arbitrary object address in the
test output.
Pretty good score for both doctest and the doc string, I'd say!
define COLORS or COLOR_PAIRS until after start_color() is called,
but they were never added to the curses module. Fixed by adding
a wrapper around start_color(), similar to the wrapper around initscr().
This applies the patch Fred Drake created to fix it.
I'm checking it in since I had to apply the patch anyway in order
to test its behavior on Windows.
used by Jython. The tests in this module expect C locale, so be
explicit about setting that (for CPython). However, in Jython, there
is no C locale, so instead be explicit about setting the US locale.
Closes the patch.
Change 1: Not all 'modules' in sys.modules have a
sensible __file__ attribute. Some of our java package
can have the __file__ attribute set to None.
Change 2: In jython we have the jython license file in
<root> and the CPython license file in <root>/Lib. By
reversing the search sequence jython will find and
show the jython license file before the CPython file.
Closes SF patch #405853.
#403666. Specifically,
In codestr, force `c' to be global. It's unclear what the semantics
should be for a code object compiled at module scope, but bound and
run in a function. In CPython, `c' is global (by accident?) while in
Jython, `c' is local. The intent of the test clearly is to make `c'
global, so let's be explicit about it.
Jython also does not have a __builtins__ name in the module's
namespace, so we use a more portable alternative (though I'm not sure
why the test requires "__builtins__" in the g namespace).
Finally, skip the new.code() test if the new module doesn't have a
`code' attribute. Jython will never have this.
Font adjustment to improve viewing in Windows (the default monospaced font,
Courier New, seems to have no reasonable size in IE!)
Improve error handling. Try very hard to distinguish between failure to
find a module and failure during the module importing process.
Improve reloading behaviour. (Still needs some work.)
Add '.' to sys.path when running as a script at the command-line.
Don't automatically assume '-g' based on the platform. We'll just have
the batch file supply -g.
createAttributeNS(), use the parallel setAttributeNode() or
setAttributeNodeNS() to add the node to the document -- do not assume
that setAttributeNode() will operate properly for both.
Factor description of import errors into DocImportError.__str__.
Add "docother" and "fail" methods to Doc class.
Factor formatting of constants into "docother".
Increase max string repr limit to 100 characters.
Factor page generation into HTMLDoc.page.
Handle aliasing of names (objects appearing under an attribute
name different from their intrinsic __name__) by passing the
attribute name into each doc* method.
Handle methods at top level of modules (e.g. in random).
Try to do reloading efficiently.
Important fixes still to do:
Module reloading is broken by the unfortunate property that
failed imports leave an incomplete module in sys. Still
need to think of a good solution.
Can't document modules in the current directory, due to the
other unfortunate property that sys.path gets '.' when
you run 'python' but it gets the script directory when
you run a script. Need to ponder to find a solution.
The synopsis() routine does not work on .so modules.
Aliases cause duplicate copies of documentation to appear.
This is easy to fix, just more work.
Classes appear as their intrinsic name, not their attribute name,
in the class hierarchy. This should be fixed.
Inherited methods should be listed in class descriptions.
# 409287, ssl fix when using _socketobject, by Robin Dunn.
I took the opportunity to improve the way it deals with reload(socket)
for the socket function as well.
cmd.py uses raw_input(); eats SIGCLD:
I discovered a rather nasty side effect of the standard cmd.py
library today. If it's sitting inside raw_input(), any SIGCLDs that
get sent to your application get silently eaten and ignored. I'm
assuming that this is something that readline is thoughtfully doing
for me.
This patch adds an instance attr that allows the user to select to
not use raw_input(), but instead use sys.stdin.readline()
[Changed slightly to catch EOFError only for raw_input().]
along with options to print them.
Add a finalize_options() method to Distribution to do final processing
on the platform and keyword attributes
Add DistributionMetadata.write_pkg_info() method to write a PKG-INFO file
into the release tree.
This makes verbose-mode output easier to dig thru, and removes an accidental
dependence on the order of dict.items() (made visible by recent changes to
dictobject.c).
