In a fresh interpreter, type.mro(tuple) would segfault, because
PyType_Ready() isn't called for tuple yet. To fix, call
PyType_Ready(type) if type->tp_dict is NULL.
Use a repr() on the subprocess side when fetching dict values for stack.
The various dict entities are not needed by the debugger GUI, only
their representation.
These built-in functions are replaced by their (now callable) type:
slice()
buffer()
and these types can also be called (but have no built-in named
function named after them)
classobj (type name used to be "class")
code
function
instance
instancemethod (type name used to be "instance method")
The module "new" has been replaced with a small backward compatibility
placeholder in Python.
A large portion of the patch simply removes the new module from
various platform-specific build recipes. The following binary Mac
project files still have references to it:
Mac/Build/PythonCore.mcp
Mac/Build/PythonStandSmall.mcp
Mac/Build/PythonStandalone.mcp
[I've tweaked the code layout and the doc strings here and there, and
added a comment to types.py about StringTypes vs. basestring. --Guido]
They still run as standalone scripts, but when used as part of the
regression test suite, they are effectively no-ops.
(This is done by renaming test_main to main.)
473985. Through a subtle rearrangement of some members in the etype
struct (!), mapping methods are now preferred over sequence methods,
which is necessary to support str.__getitem__("hello", slice(4)) etc.
Two new tests are needed:
Don't skip building an extension if any of the depends files are newer
than the target.
Pass ext.depends to compiler.compile() so that it can track individual
files.
Always use _setup_compile() to do the grunt work of processing
arguments, figuring out which files to compile, and emitting debug
messages for files that are up-to-date.
Use _get_cc_args() when possible.
This change is not backwards compatible. If a compiler subclass
exists outside the distutils package, it may get called with the
unexpected keyword arg. It's easy to extend that compiler by having
it ignore the argument, and not much harder to do the right thing. If
this ends up being burdensome, we can change it before 2.3 final to
work harder at compatibility.
Also add _setup_compile() and _get_cc_args() helper functions that
factor out much of the boilerplate for each concrete compiler class.
that retries the connect() call in timeout mode so it can be shared
between connect() and connect_ex(), and needs only a single #ifdef.
The test for this was doing funky stuff I don't approve of,
so I removed it in favor of a simpler test. This allowed me
to implement a simpler, "purer" form of the timeout retry code.
Hopefully that's enough (if you want to be fancy, use non-blocking
mode and decode the errors yourself, like before).
Remove __init__ that just called base class __init__ with same args.
Fold long argument lists into fewer, shorter lines.
Remove parens in tuple unpacks.
Don't put multiple statements on one line with a semicolon.
In find_library_file() compute the library_filename() upfront.
- setblocking(0) and settimeout(0) are now equivalent, and ditto for
setblocking(1) and settimeout(None).
- Don't raise an exception from internal_select(); let the final call
report the error (this means you will get an EAGAIN error instead of
an ETIMEDOUT error -- I don't care).
- Move the select to inside the Py_{BEGIN,END}_ALLOW_THREADS brackets,
so other theads can run (this was a bug in the original code).
- Redid the retry logic in connect() and connect_ex() to avoid masking
errors. This probably doesn't work for Windows yet; I'll fix that
next. It may also fail on other platforms, depending on what
retrying a connect does; I need help with this.
- Get rid of the retry logic in accept(). I don't think it was needed
at all. But I may be wrong.
This was a simple typo. Strange that the compiler didn't catch it!
Instead of WHY_CONTINUE, two tests used CONTINUE_LOOP, which isn't a
why_code at all, but an opcode; but even though 'why' is declared as
an enum, comparing it to an int is apparently not even worth a
warning -- not in gcc, and not in VC++. :-(
Will fix in 2.2 too.
[ 400998 ] experimental support for extended slicing on lists
somewhat spruced up and better tested than it was when I wrote it.
Includes docs & tests. The whatsnew section needs expanding, and arrays
should support extended slices -- later.
transformed them into the initial_indent and subsequent_indent instance
attributes. Now they actually work as advertised, ie. they are
accounted for in the width of each output line. Plus you can use them
with wrap() as well as fill(), and fill() went from simple-and-broken to
trivial-and-working.
metaclasses.
This is essentially the same problem as that reported in bug 494904
for pickle: deepcopy should treat instances of custom metaclasses the
same way it treats instances of type 'type'.
Bugfix candidate.
and fill() methods. Keep interface of existing wrap() and fill()
functions by going back to having them construct a new TextWrapper
instance on each call, with the preferred width passed to the
constructor.
sentences are separated by two spaces.
Improve _fix_sentence_endings() a bit -- look for ".!?" instead of just
".", and factor out the list of sentence-ending punctuation characters
to a class attribute.
I've made considerable changes to Michael's code, specifically to use
the select() system call directly and to store the timeout as a C
double instead of a Python object; internally, -1.0 (or anything
negative) represents the None from the API.
I'm not 100% sure that all corner cases are covered correctly, so
please keep an eye on this. Next I'm going to try it Windows before
Tim complains.
No way is this a bugfix candidate. :-)
Straightforward fix. Will backport to 2.2. If there's ever a new 2.1
release, this could be backported there too (since it's an issue with
anything that's got both a __reduce__ and a __setstate__).

This is a conservative version of SF patch 504889. It uses the log
module instead of calling print in various places, and it ignores the
verbose argument passed to many functions and set as an attribute on
some objects. Instead, it uses the verbosity set on the logger via
the command line.
The log module is now preferred over announce() and warn() methods
that exist only for backwards compatibility.
XXX This checkin changes a lot of modules that have no test suite and
aren't exercised by the Python build process. It will need
substantial testing.
While I was at it, I added a tp_clear handler and changed the
tp_dealloc handler to use the clear_slots helper for the tp_clear
handler.
Also tightened the rules for slot names: they must now be proper
identifiers (ignoring the dirty little fact that <ctype.h> is locale
sensitive).
Also set mp->flags = READONLY for the __weakref__ pseudo-slot.
Most of this is a 2.2 bugfix candidate; I'll apply it there myself.
# XXX this isn't used anywhere, and worse, it has the same name as a method
# in Command with subtly different semantics. (This one just has one
# source -> one dest; that one has many sources -> one dest.) Nuke it?
Yes. Nuke it.
modules, distutils does not understand that the build version of the
source tree is needed.
This patch fixes distutils.sysconfig to understand that the running
Python is part of the build tree and needs to use the appropriate
"shape" of the tree. This does not assume anything about the current
directory, so can be used to build 3rd-party modules using Python's
build tree as well.
This is useful since it allows us to use a non-installed debug-mode
Python with 3rd-party modules for testing. It as the side-effect that
set_python_build() is no longer needed (the hack which was added to
allow distutils to be used to build the "standard" extension modules).
This closes SF patch #547734.
BOM_UTF32, BOM_UTF32_LE and BOM_UTF32_BE that represent the Byte
Order Mark in UTF-8, UTF-16 and UTF-32 encodings for little and
big endian systems.
The old names BOM32_* and BOM64_* were off by a factor of 2.
This closes SF bug http://www.python.org/sf/555360
Change the module constructor (module_init) to have the signature
__init__(name:str, doc=None); this prevents the call from type_new()
to succeed. While we're at it, prevent repeated calling of
module_init for the same module from leaking the dict, changing the
semantics so that __dict__ is only initialized if NULL.
Also adding a unittest, test_module.py.
This is an incompatibility with 2.2, if anybody was instantiating the
module class before, their argument list was probably empty; so this
can't be backported to 2.2.x.
The HTTPError class tries to act as a regular response objects for
HTTP protocol errors that include full responses. If the failure is
more basic, like no valid response, the __init__ choked when it tried
to initialize its superclasses in addinfourl hierarchy that requires a
valid response.
The solution isn't elegant but seems to be effective. Do not
initialize the base classes if there isn't a file object containing
the response. In this case, user code expecting to use the addinfourl
methods will fail; but it was going to fail anyway.
It might be cleaner to factor out HTTPError into two classes, only one
of which inherits from addinfourl. Not sure that the extra complexity
would lead to any improved functionality, though.
Partial fix for SF bug # 563665.
Bug fix candidate for 2.1 and 2.2.
-f/--fromfile <filename>
option. This runs all and only the tests named in the file, in the
order given (although -x may weed that list, and -r may shuffle it).
Lines starting with '#' are ignored.
This goes a long way toward helping to automate the binary-search-like
procedure I keep reinventing by hand when a test fails due to interaction
among tests (no failure in isolation, and some unknown number of
predecessor tests need to run first -- now you can stick all the test
names in a file, and comment/uncomment blocks of lines until finding a
minimal set of predecessors).
__call__() can be 2-3x slower than the equivalent normal method.
_handle_message(): The structure of message/rfc822 message has
changed. Now parent's payload is a list of length 1, and the zeroth
element is the Message sub-object. Adjust the printing of such
message trees to reflect this change.
There's some wierdness here, but the test ran before and not after,
so I'm just hacking the change out. Someone more motivated than
me can work out what's really happening.
Raymond: *PLEASE* run the test suite before checking things like
this in!
subclasses.
MIMENonMultipart: Base class for non-multipart/* content type subclass
specializations, e.g. image/gif. This class overrides attach() which
raises an exception, since it makes no sense to attach a subpart to
e.g. an image/gif message.
MIMEMultipart: Base class for multipart/* content type subclass
specializations, e.g. multipart/mixed. Does little more than provide
a useful constructor.
If a rexec instance allows writing in the current directory (a common
thing to do), there's a way to execute bogus bytecode. Fix this by
not allowing imports from .pyc files (in a way that allows a site to
configure things so that .pyc files *are* allowed, if writing is not
allowed).
I'll apply this to 2.2 and 2.1 too.
