- Allow setting the destination install directory. If this is set then
it is used for the modules, other items (header files, etc) are not
installed, and warnings are printed if the package would have liked to.
Unfortunaltey binary installs seem broken due to a tarfile bug (#721871)
or my misunderstanding of how tarfile works.

Change test_grp to check that getgrall() and
getgrnam()/getgrgid() return consistent data.
Add error checks similar to test_pwd.py.
Port test___all__.py to PyUnit.

A small fix for bug #545855 and Greg Chapman's
addition of op code SRE_OP_MIN_REPEAT_ONE for
eliminating recursion on simple uses of pattern '*?' on a
long string.
After some more reflection (and no negative feedback), I am reverting the
original patch and applying my version, cygwinccompiler.py-shared.diff,
instead.
My reasons are the following:
1. support for older toolchains is retained
2. support for new toolchains (i.e., ld -shared) is added
The goal of my approach is to avoid breaking older toolchains while adding
better support for newer ones.
to lookup properties declared in base classes. Looking at it I'm not sure
what the official scope if the property codes is, maybe it is only the
(OSA) class in which they are used. But giving them global scope hasn't been
a problem so far.
Regenerated the standard suites, which are now also space-indented.
to iso-8859-1.
GNUTranslations._parse(): Back out the addition of a test for
Project-ID-Version in the metadata. This was deliberately removed in
response to SF patch #700839.
Also, re-organize the code in _parse() so we parse the metadata header
containing the charset parameter before we try to decode any strings
using charset.
- range() now works even if the arguments are longs with magnitude
larger than sys.maxint, as long as the total length of the sequence
fits. E.g., range(2**100, 2**101, 2**100) is the following list:
[1267650600228229401496703205376L]. (SF patch #707427.)
- Expose NullTranslations and GNUTranslations to __all__
- Set the default charset to iso-8859-1. It used to be None, which
would cause problems with .ugettext() if the file had no charset
parameter. Arguably, the po/mo file would be broken, but I still think
iso-8859-1 is a reasonable default.
- Add a "coerce" default argument to GNUTranslations's constructor. The
reason for this is that in Zope, we want all msgids and msgstrs to be
Unicode. For the latter, we could use .ugettext() but there isn't
currently a mechanism for Unicode-ifying msgids.
The plan then is that the charset parameter specifies the encoding for
both the msgids and msgstrs, and both are decoded to Unicode when read.
For example, we might encode po files with utf-8. I think the GNU
gettext tools don't care.
Since this could potentially break code [*] that wants to use the
encoded interface .gettext(), the constructor flag is added, defaulting
to False. Most code I suspect will want to set this to True and use
.ugettext().
- A few other minor changes from the Zope project, including asserting
that a zero-length msgid must have a Project-ID-Version header for it to
be counted as the metadata record.
* Doc - add doc for when functions were added
* UserString
* string object methods
* string module functions
'chars' is used for the last parameter everywhere.
These changes will be backported, since part of the changes
have already been made, but they were inconsistent.
The cygwinccompiler.get_versions() function only handles versions numbers of
the form "x.y.z". The attached patch enhances get_versions() to handle "x.y"
too (i.e., the ".z" is optional).
This change causes the unnecessary "--entry _DllMain@12" link option to be
suppressed for recent Cygwin and Mingw toolchains. Additionally, it directs
recent Mingw toolchains to use gcc instead of dllwrap during linking.
Currently, the cygwinccompiler.py compiler handling in
distutils is invoking the cygwin and mingw compilers
with the -static option.
Logically, this means that the linker should choose to
link to static libraries instead of shared/dynamically
linked libraries.
Current win32 binutils expect import libraries to have
a .dll.a suffix and static libraries to have .a suffix.
If -static is passed, it will skip the .dll.a
libraries. This is pain if one has a tree with both
static and dynamic libraries using this naming
convention, and wish to use the dynamic libraries.
The -static option being passed in distutils is to get
around a bug in old versions of binutils where it would
get confused when it found the DLLs themselves.
The decision to use static or shared libraries is site
or package specific, and should be left to the setup
script or to command line options.
These never failed in 2.3, and the tests confirm it. They still blow up
in the 2.2 branch, despite that all the gc-vs-__del__ fixes from 2.3
have been backported (and this is expected -- 2.2 needs more work than
2.3 needed).
of PyObject_HasAttr(); the former promises never to execute
arbitrary Python code. Undid many of the changes recently made to
worm around the worst consequences of that PyObject_HasAttr() could
execute arbitrary Python code.
Compatibility is hard to discuss, because the dangerous cases are
so perverse, and much of this appears to rely on implementation
accidents.
To start with, using hasattr() to check for __del__ wasn't only
dangerous, in some cases it was wrong: if an instance of an old-
style class didn't have "__del__" in its instance dict or in any
base class dict, but a getattr hook said __del__ existed, then
hasattr() said "yes, this object has a __del__". But
instance_dealloc() ignores the possibility of getattr hooks when
looking for a __del__, so while object.__del__ succeeds, no
__del__ method is called when the object is deleted. gc was
therefore incorrect in believing that the object had a finalizer.
The new method doesn't suffer that problem (like instance_dealloc(),
_PyObject_Lookup() doesn't believe __del__ exists in that case), but
does suffer a somewhat opposite-- and even more obscure --oddity:
if an instance of an old-style class doesn't have "__del__" in its
instance dict, and a base class does have "__del__" in its dict,
and the first base class with a "__del__" associates it with a
descriptor (an object with a __get__ method), *and* if that
descriptor raises an exception when __get__ is called, then
(a) the current method believes the instance does have a __del__,
but (b) hasattr() does not believe the instance has a __del__.
While these disagree, I believe the new method is "more correct":
because the descriptor *will* be called when the object is
destructed, it can execute arbitrary Python code at the time the
object is destructed, and that's really what gc means by "has a
finalizer": not specifically a __del__ method, but more generally
the possibility of executing arbitrary Python code at object
destruction time. Code in a descriptor's __get__() executed at
destruction time can be just as problematic as code in a
__del__() executed then.
So I believe the new method is better on all counts.
Bugfix candidate, but it's unclear to me how all this differs in
the 2.2 branch (e.g., new-style and old-style classes already
took different gc paths in 2.3 before this last round of patches,
but don't in the 2.2 branch).
externally unreachable objects with finalizers, and externally unreachable
objects without finalizers reachable from such objects. This allows us
to call has_finalizer() at most once per object, and so limit the pain of
nasty getattr hooks. This fixes the failing "boom 2" example Jeremy
posted (a non-printing variant of which is now part of test_gc), via never
triggering the nasty part of its __getattr__ method.
