inspect.py, and pydoc.py. Specifically, this allows for querying the type of
an object against these built-in C types and more importantly, for getting
their docstrings printed in the interactive interpreter's help() function.
This patch includes a new built-in module called _types which provides
definitions of getset and member descriptors for use by the types.py module.
These types are exposed as types.GetSetDescriptorType and
types.MemberDescriptorType. Query functions are provided as
inspect.isgetsetdescriptor() and inspect.ismemberdescriptor(). The
implementations of these are robust enough to work with Python implementations
other than CPython, which may not have these fundamental types.
The patch also includes documentation and test suite updates.
I commit these changes now under these guiding principles:
1. Silence is assent. The release manager has not said "no", and of the few
people that cared enough to respond to the thread, the worst vote was "0".
2. It's easier to ask for forgiveness than permission.
3. It's so dang easy to revert stuff in svn, that you could view this as a
forcing function. :)
Windows build patches will follow.
points out there are really two types of continued headers defined in this
RFC (i.e. "encoded" parameters with the form "name*0*=" and unencoded
parameters with the form "name*0="), but we were were handling them both the
same way and that isn't correct.
This patch should be much more RFC compliant in that only encoded params are
%-decoded and the charset/language information is only extract if there are
any encoded params in the segments. If there are no encoded params then the
RFC says that there will be no charset/language parts.
Note however that this will change the return value for Message.get_param() in
some cases. For example, whereas before if you had all unencoded param
continuations you would have still gotten a 3-tuple back from this method
(with charset and language == None), you will now get just a string. I don't
believe this is a backward incompatible change though because the
documentation for this method already indicates that either return value is
possible and that you must do an isinstance(val, tuple) check to discriminate
between the two. (Yeah that API kind of sucks but we can't change /that/
without breaking code.)
Test cases, some documentation updates, and a NEWS item accompany this patch.
of values in the time tuple passed in. Unfortunately people came to rely on
undocumented behaviour of setting unneeded values to 0, regardless of if it was
within the valid range. Now those values force the value internally to the
minimum value when 0 is passed in.
/F wrote the text docs, Englebert Gruber massaged it to latex and I
did some more massaging to try and improve the consistency and
fix some name mismatches between the declaration and text.
Fix doctest example.
Mention in the tutorial that 'errcheck' is explained in the ref manual.
Use better wording in some places.
Remoce code examples that shouldn't be in the tutorial.
Remove some XXX notices.
adjacent triples in the result list describe non-adjacent matching
blocks. That's _nice_ to have, and Guido said he wanted it.
Not a bugfix candidate: Guido or not ;-), this changes visible
endcase semantics (note that some tests had to change), and
nothing about this was documented before. Since it was working
as designed, and behavior was consistent with the docs, it wasn't
"a bug".
Heavily revised, comprising revisions:
46640 - original trunk revision (backed out in r46655)
46647 - markup fix (backed out in r46655)
46692:46918 merged from branch aimacintyre-sf1454481
branch tested on buildbots (Windows buildbots had problems
not related to these changes).
46640 Patch #1454481: Make thread stack size runtime tunable.
46647 Markup fix
The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like
svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH
followed by merging rev 46647 to the new branch.
the output required more than one line. "Small" dicts got
displayed in seemingly random order (the hash-induced order
produced by dict.__repr__). None of this was documented.
Now pprint functions always sort dicts by key, and the docs
promise it.
This was proposed and agreed to during the PyCon 2006 core
sprint -- I just didn't have time for it before now.
SimpleXMLRPCServer and DocXMLRPCServer don't look at
the path of the HTTP request at all; you can POST or
GET from / or /RPC2 or /blahblahblah with the same results.
Security scanners that look for /cgi-bin/phf will therefore report
lots of vulnerabilities.
Fix: add a .rpc_paths attribute to the SimpleXMLRPCServer class,
and report a 404 error if the path isn't on the allowed list.
Possibly-controversial aspect of this change: the default makes only
'/' and '/RPC2' legal. Maybe this will break people's applications
(though I doubt it). We could just set the default to an empty tuple,
which would exactly match the current behaviour.
Renames functional extension module to _functools and adds a Python
functools module so that utility functions like update_wrapper can be
added easily.
discussion.
There are two places of documentation that still mention __context__:
Doc/lib/libstdtypes.tex -- I wasn't quite sure how to rewrite that without
spending a whole lot of time thinking about it; and whatsnew, which Andrew
usually likes to change himself.
This may be a useful style question for the docs -- should examples show
the necessary imports, or should it be assumed that the reader will
figure it out? In the What's New, I'm not consistent but usually opt
for omitting the imports.
terminology in the alpha 1 documentation.
- "context manager" reverts to its alpha 1 definition
- the term "context specifier" goes away entirely
- contextlib.GeneratorContextManager is renamed GeneratorContext
There are still a number of changes relative to alpha 1:
- the expression in the with statement is explicitly called the
"context expression" in the language reference
- the terms 'with statement context', 'context object' or 'with
statement context' are used in several places instead of a bare
'context'. The aim of this is to avoid ambiguity in relation to the
runtime context set up when the block is executed, and the context
objects that already exist in various application domains (such as
decimal.Context)
- contextlib.contextmanager is renamed to contextfactory
This best reflects the nature of the function resulting from the
use of that decorator
- decimal.ContextManager is renamed to WithStatementContext
Simple dropping the 'Manager' part wasn't possible due to the
fact that decimal.Context already exists and means something
different. WithStatementContext is ugly but workable.
A technically unrelated change snuck into this commit:
contextlib.closing now avoids the overhead of creating a
generator, since it's trivial to implement that particular
context manager directly.
