Patch by Case Roole <cjr@bound.xs4all.nl> to fail with a more
explanatory message when the manual directories aren't found.
(I have to say I'm surprised that it actually still works!)
When creating a class, set its __module__ attribute to the module
whose name is in the current globals' __name__ variable. If __name__
is not set, ignore this.
As Paul Prescod pointed out, metaprogramming is really something
different (programs that write programs). We are dealing with
metaclasses here. So change the words slightly.
Update the description and the example to the new functionality, which
is mostly concentrated in a generalized find_module() and the new
load_module(). Added the new module type constants. Declare that
SEARCH_ERROR and a whole bunch of module-type-specific functions are
obsolete.
Crrected a flow control error that caused the wrong error message when
load-module() didn't find a built-in or frozen module. Also got rid
of is_frozen(), which duplicated the functionality of
find_frozen()!=NULL.
Patch submitted by Brad Howes (with one bug fixed by me): allow
arbitrary nested parens in a %(...)X style format.
#Also folded two lines and added more detail to the error message for
#unsupported format character.

Major overhaul: this is now little more than a user interface, the
preference handling code is in modules pythonprefs and preferences.
This should finally make it easier for someone (Just?) to write a
decent interface to preference setting, and it'll allow setting
initial sys.path and such from ConfigurePython.
Initialize self.__tempfiles to [] in the constructor (else it remains
a shared class variable -- but each instance will attempt to clean it
up entirely ob cleanup).
*Semantic change*: when unpickling the instance variables of an
instance, use inst.__dict__.update(value) instead of a for loop with
setattr() over the value.keys(). This is more consistent (the
pickling doesn't use getattr() either but pickles inst.__dict__) and
avoids problems with instances that have a __setattr__ hook.
But it *is* a semantic change (because the setattr hook is no longer
used). So beware!
Change the names of the subdirectories tkinter and stdwin to
lib-tk and lib-stdwin. (BTW this was also done in the previous
checkin of (toplevel)/Makefile.in, though not noted in the checkin
message.)
Look for uuencoded test files in the directory containing this module, too.
(This is necessary because when imported as test.test_rgbimg, the test
directory is not on sys.path.)

Reverse the order in which Setup and Setup.local are passed to the
makesetup script. (Sorry Sjoerd -- I know you proposed this a while
ago and I didn't think it would work then. I looked again and it
does work.)
Fix details in the test:
- traceback should go to stdout!
- don't import ni, import t1!
- nicer support for command line options, only if run as __main__
Significant speedup -- when a submodule imports a global module, add a
dummy entry to sys.modules, marking the absence of a submodule by the
same name.
Thus, if module foo.bar executes the statement "import time",
sys.modules['foo.time'] will be set to None, once the absence of a
module foo.time is confirmed (by looking for it in foo's path).
The next time when foo.bar (or any other submodule of foo) executes
"import time", no I/O is necessary to determine that there is no
module foo.time.
(Justification: It may seem strange to pollute sys.modules. However,
since we're doing the lookup anyway it's definitely the fastest
solution. This is the same convention that 'ni' uses and I haven't
heard any complaints.)
Phase two of package import. "import a.b.c" and all variants now do the
right thing.
Still to do:
- Make reload() of a submodule work.
- Performance tweaks -- currently, a submodule that tries to import a
global module *always* searches the package directory first, even if
the global module was already imported. Not sure how to solve this
one; probably need to record misses per package.
Fixed some details of printing the str() of an exception. This fixes
a core dump when __str__() returns a non-string, and plugs a memory
leak as well: the result of PyObject_Str() was never DECREFed.
This doesn't yet support "import a.b.c" or "from a.b.c import x", but
it does recognize directories. When importing a directory, it
initializes __path__ to a list containing the directory name, and
loads the __init__ module if found.
The (internal) find_module() and load_module() functions are
restructured so that they both also handle built-in and frozen modules
and Mac resources (and directories of course). The imp module's
find_module() and (new) load_module() also have this functionality.
Moreover, imp unconditionally defines constants for all module types,
and has two more new functions: find_module_in_package() and
find_module_in_directory().
There's also a new API function, PyImport_ImportModuleEx(), which
takes all four __import__ arguments (name, globals, locals, fromlist).
The last three may be NULL. This is currently the same as
PyImport_ImportModule() but in the future it will be able to do
relative dotted-path imports.
Other changes:
- bltinmodule.c: in __import__, call PyImport_ImportModuleEx().
- ceval.c: always pass the fromlist to __import__, even if it is a C
function, so PyImport_ImportModuleEx() is useful.
- getmtime.c: the function has a second argument, the FILE*, on which
it applies fstat(). According to Sjoerd this is much faster. The
first (pathname) argument is ignored, but remains for backward
compatibility (so the Mac version still works without changes).
By cleverly combining the new imp functionality, the full support for
dotted names in Python (mini.py, not checked in) is now about 7K,
lavishly commented (vs. 14K for ni plus 11K for ihooks, also lavishly
commented).
Added PyImport_ImportModuleEx(name, globals, locals, fromlist); this
is like PyImport_ImporModule(name) but receives the globals and locals
dict and the fromlist arguments as well. (The name is a char*; the
others are PyObject*s).
Contribution by Hannu Krosing (with some changes).
Added 'p' format character for Pascal string (i.e. leading length
byte). This uses the count prefix line 's' does, except that the
count includes the length byte; i.e. '10p' takes 10 bytes packed but
has space for a length byte and 9 data bytes.

Several changes:
1. Fix bug in (de)compression objects. The final string resize used
zst.total_out to determine the length of the string, but the
(de)compression object will output data a little bit at a time, which
means total_out is not the string size. Fix: save original value of
total_out at the start of the call.
2. Be sure to Py_DECREF the result value if you exit with an
exception.
3. Use PyInt_FromLong instead of Py_BuildValue
4. include more constants from the zlib header file
5. Use PyErr_Format instead of using a local buffer and sprintf.
Added some try-excepts so that it can be imported in restricted mode
(though some type names are undefined in that case, e.g. CodeType
(inaccessible), FileType (not always accessible), and TracebackType
and FrameType (inaccessible).
Sjoerd: add separate administration of temporary files created y
URLopener.retrieve() so cleanup can properly remove them. The old
code removed everything in tempcache which was a bad idea if the user
had passed a non-temp file into it. (I added a line to delete the
tempcache in cleanup() -- it still seems to make sense.)
Jack: in basejoin(), interpret relative paths starting in "../". This
is necessary if the server uses symbolic links.
- use the DLL versions of the C runtime (!)
- change path settings so intermediate files go to Debug/temp or Release/temp
- add resource file to python15.dll (can't remember what this does)
- add a separate project to build the parser module
