Let's hope this is correct (I'm not sure why the sys.platform would be
'Darwin1.2' rather than 'darwin1', which seems to be the convention).
Someone with Darwin please test this!
libm result is 0). Cautiously add a few libm exception test cases:
1. That exp(-huge) returns 0 without exception.
2. That exp(+huge) triggers OverflowError.
3. That sqrt(-1) raises ValueError specifically (apparently under glibc linked
with -lieee, it was raising OverflowError due to an accident of the way
mathmodule.c's CHECK() macro happened to deal with Infs and NaNs under gcc).

didn't bother to close the files. This caused the new test_wave test to fail
under Windows, as Windows won't let you delete a file that's open. Fixed
that by ensuring the wave read & write classes' .close() and __del__ methods

Remove the lines that set the variables holding dom objects to None; not

[Note: I'm not sure that this is really the right fix. Surely Darwin
doesn't require you to say "python.exe" everywhere??? Even Windows
doesn't! Or am I misunderstanding the point?]
tokenize.py has always used naive regexps for matching string literals,
and that appears to trigger the sre recursion limit on Skip's platform (he
has very long single-line string literals). Replaced all of tokenize.py's
string regexps with the "unrolled" forms used in IDLE, where they're known to
handle even absurd (multi-megabyte!) string literals without trouble. See
Friedl's book for explanation (at heart, the naive regexps create a backtracking
choice point for each character in the literal, while the unrolled forms create
none).

raise ValueError. Checked in the patch as far as it went, but also changed
all of ints, longs and floats to raise ZeroDivisionError instead when raising
0 to a negative number. This is what 754-inspired stds require, as the "true
result" is an infinity obtained from finite operands, i.e. it's a singularity.
Also changed float pow to not be so timid about using its square-and-multiply
algorithm. Note that what math.pow does is unrelated to what builtin pow
does, and will still vary by platform.
1. repr(license) will no longer print to stdout and read from stdin;
you have to use license(). `license` is a short message explaining
this.
2. Use lazy initialization so that startup isn't slowed down by the
search for the LICENSE file.
3. repr(license) actually returns the desired string, rather than
printing to stdout and returning ''. (Why didn't we think of this
before?)
4. Use the pythonlabs license URL as the license fallback instead of
the CNRI license handle.
apparently not considered a terminal, and so isatty(3) returns false. So we
skip the test for ttyness of the master side and just check the slave side,
which should really be a terminal.
CGI scripts should *not* use /usr/bin/env, since on systems that don't
come standard with Python installed, Python isn't on the default $PATH.
Too bad that this breaks on Linux, where Python is in /usr/bin which
is on the default path -- the point is that you must manually edit
your CGI scripts when you install them.
about how it would be nice to write absolute paths to the temporary
byte-compilation script, but this doesn't work because it screws up the
trailing-slash trickery done to 'prefix' in build_py's 'byte_compile()'
method.
Fixed to use 'execute()' instead of 'os.remove()' to remove the temporary
script: now it doesn't blow up in dry-run mode!
invalid proxy setting.
Minor change to call of unknown_url; always pass data argument

by default (since compiling at install time works just fine). Details:
- added 'compile' and 'optimize' options
- added 'byte_compile()' method
- changed 'get_outputs()' so it includes bytecode files
A lot of the code added is very similar to code in install_lib.py;
would be nice to factor it out further.
choice between (compile, no-compile) * (optimize=0, optimize=1,
optimize=2). Details:
- added --no-compile option to complement --compile, which has
been there for ages
- changed --optimize (which never worked) to a value option, which
expects 0, 1, or 2
- renamed 'bytecompile()' method to 'byte_compile()', and beefed
it up to handle both 'compile' and 'optimize' options
- fix '_bytecode_filenames()' to respect the new options
standard 'py_compile.compile()' function. Laundry list of features:
- handles standard Distutils 'force', 'verbose', 'dry_run' flags
- handles various levels of optimization: can compile directly in
this interpreter process, or write a temporary script that is
then executed by a new interpreter with the appropriate flags
- can rewrite the source filename by stripping an optional prefix
and preprending an optional base dir.
- added 'sub_commands' class attr
- added 'has_*()' predicates referenced by the sub-command list
- rewrote 'run()' so it's a trivial loop over relevant sub-commands
They are unneeded: All this stuff is already done by the
install command which is run by bdist_wininst.
One bug has been fixed:
The root of the fake install tree is install.install_purelib,
not install.install_lib!
They are different if the extra_path option is used in
the setup function.
Rebuild after the changes to wininst.exe.
Removed get_ext_libname() because it is unused.
Fixed get_libraries() to append an '_d' to the python debug
import library. If MSVC is used, do not add 'pythonxx.lib' to
the list of libraries, because this is handled better
by a pragma in config.h.
This should fix bug #115595, but it needs some more testing.
popen2(), popen3(): Reversed order of bufsize and mode parameters to
comply with what was here before (Python 1.5.2).
class Popen3: Factored the __init__() into a more basic initializer and

Use os.dup2() instead of os.dup() to create the proper

__file__ attributes of already-imported modules to be absolute. This helps
robustify the interpreter against os.chdir() calls from the application.
Only remove setdefaultencoding() from sys if it exists; if this module is
run as a script (since there is a _test() function that gets run), it broke
because the script attempts to remove it again after the import of site
has already done so. This allows the module to be run as a script again.
makepath(): New function, standardizes all pathname normalization in one
place.
cStringIO does not get it right (reported as SF bug #115531).
Added test for ValueError when write() is called on a closed StringIO
object. Commented out because cStringIO does not get it right
(reported as SF bug #115530).
Do not expose the __name__ when reporting the list of options available
for a section since that is for internal use.
This closes SourceForge bug #115357.
Additionally, define InterpolationDepthError and MAX_INTERPOLATION_DEPTH.
The exception is raised by get*() when value interpolation cannot be
completed within the defined recursion limit. The constant is only
informative; changing it will not affect the allowed depth.
Fix the exit from get() so that None is not returned if the depth is met
or exceeded; either return the value of raise InterpolationDepthError.
implementations. Details:
* replace 'link_shared_object()', 'link_shared_lib()', and
'link_executable()' with 'link()', which is (roughly)
the union of the three methods it replaces
* in all implementation classes (UnixCCompiler, MSVCCompiler, etc.),
ditch the old 'link_*()' methods and replace them with 'link()'
* in the abstract base class (CCompiler), add the old 'link_*()'
methods as wrappers around the new 'link()' (they also print
a warning of the deprecated interface)
Also increases consistency between MSVCCompiler and BCPPCompiler,
hopefully to make it easier to factor out the mythical WindowsCCompiler
class. Details:
* use 'self.linker' instead of 'self.link'
* add ability to compile resource files to BCPPCompiler
* added (redundant?) 'object_filename()' method to BCPPCompiler
* only generate a .def file if 'export_symbols' defined
caused the drive letter to cause urlopen() to think it was an unrecognized
URL scheme. This only passes system ids to urlopen() if the file does not
exist. It works on Windows & Unix.
It should work everywhere else as well.
self.optionxform(), which (in the default case) caused options spelled
with opper case letters in their name to be inaccessible. Reported by
"Todd R. Palmer" <t2palmer@bellsouth.net> on
activepython@listserv1.ActiveState.com.
* options can now be spelled "foo-bar" or "foo_bar" (handled in
'parse_config_files()', just after we parse a file)
* added a "[global]" section so there's a place to set global
options like verbose/quiet and dry-run
* respect the "negative alias" dictionary so (eg.) "quiet=1" is
the same as "verbose=0" (this had to be done twice: once in
'parse_config_file()' for global options, and once in
'_set_command_options()' for per-command options)
* the other half of handling boolean options correctly: allow
commands to list their boolean options in a 'boolean_options'
class attribute, and use it to translate strings (like "yes", "1",
"no", "0", etc) to true or false
xml.sax: Fix parse and parseString not to rely on ExpatParser
Greatly simplify import logic by using __import__

The earlier code assumed "protocol=host;protocol=host;..." or "host",
but Windows may also use "protocol=host" (just one entry), as well as
"protocol://host". This code needs some more work, so I'll leave the
bug open for now.
subset of Win32 ShellExecute's functionality. Guido wants this because
IDLE's Help -> Docs function currently crashes his machine because of a
conflict between his version of Norton AntiVirus (6.10.20) and MS's
_popen. Docs for startfile are being mailed to Fred (or just read the
docstring -- it tells the whole story).
Changed webbrowser.py to use os.startfile instead of os.popen on Windows.
Changed IDLE's EditorWindow.py to pass an absolute path for the docs
(hardcoding ShellExecute's "directory" arg to "." as used to be done let
IDLE work, but made the startfile command exceedingly obscure for other
uses -- the MS docs are terrible, of course, & still not sure I
understand it).
Note that Windows Python must link with shell32.lib now! That's where
ShellExecute lives.
'convert_paths()' method to convert them all to the local syntax (backslash
or colon or whatever) at the appropriate time.
Added SCHEME_KEYS to get rid of one hard-coded list of attributes (in
'select_scheme()').
Default 'install_path_file' to true, and never set it false (it's just
there in case some outsider somewhere wants to disable installation of the
.pth file for whatever reason).
Toned down the warning emitted when 'install_path_file' is false, since we
no longer know why it might be false.
Added 'warn_dir' flag to suppress warning when installing to a directory
not in sys.path (again, we never set this false -- it's there for outsiders
to use, specifically the "bdist_*" commands).
Pulled the loop of 'change_root()' calls out to new method 'change_roots()'.
Comment updates/deletions/additions.
flag is true, is set to a StringIO object that silently collects all
debug messages. This is triggered by the Node._debug=1 statement at
the top of test_minidom.py. After the tests, we better delete that
StringIO object to avoid wasting memory. We also reset the _debug
flag. (Note that this is an undetectable memory leak, and the memory
doesn't get collected by the cycle-gc either, because it's all
reachable -- it's just useless.)
Add support for parsing already-opened files. Make sure the parse()
method closes exactly those files that it opens.
Modified by FLD for better conformance to the Python style guide.
This closes SourceForge patch #101512.
Note a curious extension to the std C rules: x, X and o formatting can never produce
a sign character in C, so the '+' and ' ' flags are meaningless for them. But
unbounded ints *can* produce a sign character under these conversions (no fixed-
width bitstring is wide enough to hold all negative values in 2's-comp form). So
these flags become meaningful in Python when formatting a Python long which is too
big to fit in a C long. This required shuffling around existing code, which hacked
x and X conversions to death when both the '#' and '0' flags were specified: the
hacks weren't strong enough to deal with the simultaneous possibility of the ' ' or
'+' flags too, since signs were always meaningless before for x and X conversions.
Isomorphic shuffling was required in unicodeobject.c.
Also added dozens of non-trivial new unbounded-int test cases to test_format.py.
resource files. The gist of the patch is to treat ".rc" and ".mc"
files as source files; ".mc" files are compiled to ".rc" and then
".res", and ".rc" files are compiled to ".res". Wish I knew what
all these things stood for...
which implements the automatic conversion from Unicode to a string
object using the default encoding.
The new API is then put to use to have eval() and exec accept
Unicode objects as code parameter. This closes bugs #110924
and #113890.
As side-effect, the traditional C APIs PyString_Size() and
PyString_AsString() will also accept Unicode objects as
parameters.
style conventions. (Ping has checkin privileges but apparently
ignores them at the moment.)
Ping improves a few doc strings and fixes style violations like foo ( bar ).
An addition of my own: rearrange the printing of various items in
test() so that the (long) environment comes at the end. This avoids
having to scroll if you want to see the current directory or command
line arguments.
interface consistent: The client is responsible for closing the
socket, regardless of the amount of data received.
Restore suport for set_debuglevel call.
default encoding ("ascii") is changed. This safes quite a few cycles
during startup since the first call to .setdefaultencoding() will
initialize the codec registry and the encodings package.
See python-dev for a discussion (Subject: "[Python-Dev] [comp.lang.python] sys.setdefaultencoding (2.0b1)").
in a string (gives you something to do with the dictionary returned
by 'parse_makefile()').
Pulled the regexes in 'parse_makefile()' out -- they're now globals,
as 'expand_makefile_vars()' needs (two of) them.
Cosmetic tweaks to 'parse_makefile()'.
easier for people porting Makefile.pre.in-based extensions to Distutils.
Also loosened argument-checking in Extension constructor to make life
easier for 'read_setup_file()'.
reverse() didn't work at all due to bad arg check.
Fixed that.
Added Brad Chapman to ACKS file, as the proud new owner of two
implicitly copyrighted lines of Python source code <wink>.
Repaired buffer_info's total lack of arg-checking.
Replaced memmove by memcpy in reverse() guts, as memmove is
often slower and the memory areas are guaranteed disjoint.
Replaced poke-and-hope unchecked decl of tmp buffer size by
assert-checked larger tmp buffer.
Got rid of inconsistent spaces before open paren in docstrings.
Added reverse() sanity tests to test_array.py.
are completely skipped, rather than being treated as blank lines
(and then subject to the 'skip_blanks' flag). This allows us
to process old-style Setup files, which rely on
hello \\

there
coming out as "hello there".
Dropped the 'collapse_ws' option and replaced it with 'collapse_join' --
it's *much* faster (no 're.sub()') and this is the reason I really added
'collapse_ws', ie. to remove leading whitespace from a line being joined
to the previous line.
(eg. "bdist_dumb", to generate both ZIP and tar archives in the same
run), tell all but the last run to keep temp files -- this just gets
rid of the need to pseudo-install the same files multiple times.

we want to be be able to run (eg.) "install" twice in one run, as happens
when generating multiple built distributions in one run.
families" -- eg. install and its brood, build and its brood, and so forth.
Specifically: added the 'sub_commands' class attribute (empty list, sub-
classes must override it) and a comment describing it, and the
'get_sub_commands()' method.
Strings are unpickled by calling eval on the string's repr. This
change makes pickle work like cPickle; it checks if the pickled
string is safe to eval and raises ValueError if it is not.
test suite modifications:
Verify that pickle catches a variety of insecure string pickles
Make test_pickle and test_cpickle use exactly the same test suite
Add test for pickling recursive object
of globals from sysconfig.
Added 'prefix' and 'exec_prefix' to the list of variables that can be
expanded in installation directories (preserving the stupid old names
of 'sys_prefix' and 'sys_exec_prefix, though).
all that work when someone asks for a "configuration variable" from the
Makefile. Details:
- added 'get_config_vars()': responsible for calling one of the
'_init_*()' functions to figure things out for this platform,
and to provide an interface to the resulting dictionary
- added 'get_config_var()' as a simple interface to the dictionary
loaded by 'get_config_vars()'
- changed the '_init_*()' functions so they load the global dictionary
'_config_vars', rather than spewing their findings all over
the module namespace
- don't delete the '_init_*()' functions when done importing
- adjusted 'customize_compiler()' to the new regime
character according to RFC 2396. Add some text to quote doc string
that explains the quoting rules better.
This closes SF Bug #114427.
Add _fast_quote operation that uses a dictionary instead of a list
when the standard set of safe characters is used.
mailbox.py (from the CVS tree) doesn't work with qmail Maildirs:
Filenames are completed when the directories are scanned, and
the directory name is prepended again in the next() method.
Another suggestion: Change the print statement in the _test()
driver to show two more date characters (probably the length
has increased due to the recent Y2K hype ;). Now it shows the
complete date, including the seconds -- at least for me. (I've
also made the sender field left justified, in case it is ever
shorter than the field width).
used to create the distribution and the creation date.
Takes care of the extra_path argument to the setup function,
installs the modules into <prefix>/extra_path and creates
a -pth file (like install_lib does).
Paid more attention to the comments on the report; Martin suggested just
not having a __del__() method, which makes more sense in this case. So
I have removed it.
This closes SourceForge bug #113850. Again.
The posixfile __del__ method attempts to close the file (_file_) it
contains. However, if the open() method fails, then _file_ is never
assigned.
This closes SourceForge bug #113850.
distutils/command/bdist_wininst.py:
- the windows installer is again able to compile after installing
the files. Note: The default has changed, the packager has to
give --no-target-compile/--no-target-optimize to NOT compile
on the target system. (Another note: install_lib's --compile
--optimize options have the same semantics to switch off
the compilation. Shouldn't the names change?)
- All references to specific python versions are gone.
- A small bug:
raise DistutilsPlatformError ("...")
instead of
raise DistutilsPlatformError, ("...")
- When bdist_wininst creates an installer for one specific python
version, this is reflected in the name:
Distutils-0.9.2.win32-py15.exe instead of
Distutils-0.9.2.win32.exe
- bdist_wininst, when run as script, reads the wininst.exe file
and rewrites itself. Previously this was done by hand.
