file uploads.
In response to SF bugs 110674 and 119806, and discussions on
python-dev, we are removing the self.lines attribute from the
FieldStorage class. Specifically touched where methods __init__(),
read_lines_to_eof(), and skip_lines().
No one can remember why self.lines was added. Technically, it's part
of the public interface for the class, but it was never documented.
It's possible clever or nosy code will break because of this, but it
was decided to remove it and see who complains.
This resolution also closes the second half of the cgi.py entry in PEP
42. The first half of that PEP concerns specifically binary file
uploads, where there may be no end-of-line marker for a very long
time. This patch does not address that issue.
embedded code objects (e.g. functions) rather than the generated code
object. This change means that the compiler generates code for
everything at the end, rather then generating code for each function
as it finds it. Implementation note: _convert_LOAD_CONST in
pyassem.py must be change to call getCode().
Other changes follow. Several changes creates extra edges between
basic blocks to reflect control flow for loops and exceptions. These
missing edges had gone unnoticed because they do not affect the
current compilation process.
pyassem.py:
Add _enable_debug() and _disable_debug() methods that print
instructions and blocks to stdout as they are generated.
Add edges between blocks for instructions like SETUP_LOOP,
FOR_LOOP, etc.
Add pruneNext to get rid of bogus edges remaining after
unconditional transfer ops (e.g. JUMP_FORWARD)
Change repr of Block to omit block length.
pycodegen.py:
Make sure a new block is started after FOR_LOOP, etc.
Change assert implementation to use RAISE_VARARGS 1 when there is
no user-specified failure output.
misc.py:
Implement __contains__ and copy for Set.
When a method is called with no regular arguments and * args, defer
the first arg is subclass check until after the * args have been
expanded.
N.B. The CALL_FUNCTION implementation is getting really hairy; should
review it to see if it can be simplified.
-- fixed negative lookbehind to work correctly at the beginning
of the target string (bug #117242)
-- improved syntax check; you can no longer refer to a group
inside itself (bug #110866)
Reformatting -- long lines, "[ ]" -> "[]", a few indentation nits.
Replace calls to Node function (which constructed ast nodes) with
calls to actual constructors imported from ast module.
Optimize com_node (most frequently used method) for the common case --
the appropriate method is found in _dispatch.
Fix com_augassign to use class object's rather than node names
(rendered invalid by recent changes to ast)
Remove expensive tests for sequence-ness in com_stmt and
com_append_stmt. These tests should never fail; if they do, something
is really broken and exception will be raised elsewhere.
Fix com_stmt and com_append_stmt to use isinstance rather than
testing's type slot of ast node (this slot disappeared with recent
changes to ast).
Betlehem, verified by Peter Funk. Fixes preservation of language
search order lost due to use of dictionary keys instead of a list.
Closes SF bug #116964.
1.5.2. The compiler generates code for the version of the interpreter
it is run under.
ast.py:
Print and Printnl add dest attr for extended print
new node AugAssign for augmented assignments
new nodes ListComp, ListCompFor, and ListCompIf for list
comprehensions
pyassem.py:
add work around for string-Unicode comparison raising UnicodeError
on comparison of two objects in code object's const table
pycodegen.py:
define VERSION, the Python major version number
get magic number using imp.get_magic() instead of hard coding
implement list comprehensions, extended print, and augmented
assignment; augmented assignment uses Delegator classes (see
doc string)
fix import and tuple unpacking for 1.5.2
transformer.py:
various changes to support new 2.0 grammar and old 1.5 grammar
add debug_tree helper than converts and symbol and token numbers
to their names
First, only report garbage that the GC cannot free. Second, only report
the number of objects found, not their repr(). People can dig deeper on
their own if they find a leak.
- don't close the fp, since that appears to also close the socket
- join the original url with the redirect reponse to deal with
relative redirect URL
wrap two socket ops in try/except to turn them into URLErrors, so that
client code need only catch one exception.
in HTTPError.__del__ only close fp if fp is not None
style changes:
- use f(*args) instead of apply(f, args)
- use __super_init instead of super.__init__(self, ...)
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).
support for extension types, not classes.

This (partially) closes SourceForge patch #101859.
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
close files that were opened by their constructors.
driver code, so that each test gets this; it had been done inconsistently.
Remove the lines that set the variables holding dom objects to None; not
needed since the interpreter cleans up locals on function return.
Lownds. (#101816)
[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
explicitly since data defaults to None.
PEP 42: Add as a feature that urllib handle proxy setting that contain
only the host and port of the proxy.
Linux distributions which provide both KDE and Gnome set this environment

Konquerer if KDE is not running unless the user actually tells us to!
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
a helper method, to allow some re-use by the Popen4 class.
Use os.dup2() instead of os.dup() to create the proper
file descriptors in the child process.
This closes SourceForge bug #115330 and partially closes#115353.
__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.
