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.
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).
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
parsing functions in support of auto-indent weren't expecting Unicode
strings, but text.get() can now return them (although it remains muddy as
to exactly when or why that can happen). Fixed that with a Big Hammer.
- use unidb compression for the unicodectype module. smaller,
faster, and slightly more portable...
- also mention the unicode directory in Tools/README
- fixed attributions
- moved decomposition data to a separate table, in preparation
for step 3 (which won't happen before 2.0 final, promise!)
- use relative paths in the generator script
I have a lot more stuff in the works for 2.1, but let's leave
that for another day...
a bit, sped it a lot primarily by removing the unused assumption that None was
a legit bin entry (the function doesn't really need to assume that there's
anything special about 0), added an optional "trace" argument, and in __debug__
mode added exhaustive verification that the decomposition is both correct and
doesn't overstep any array bounds (which wasn't obvious to me from staring at the
generated C code -- now I feel safe!). Did not commit a new unicodedata_db.h, as
the one produced by this version is identical to the one already checked in.
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.
The cause was that the replace code necessarily used a PCRE internal
function to to template expansion.
The fix changes the code to use an SRE internal if SRE is used, and a
PCRE internal if SRE is used; in a way that should work with 1.5.2.
The solution can be sped up tremendously under the assumption that the
choice between sre and pre is not changed during the execution of the
program; especially replace-all will be slow.
But I'll leave that to someone else.
created. This allows the application-specific Tkinter
initialization to be executed if present. Also pass an explicit
className parameter to the Tk() constructor.
This closes SourceForge bug #110618.
Fix import support to work with import as variant of Python 2.0. The
grammar for import changed, requiring changes in transformer and code
generator, even to handle compilation of imports with as.

typos, and to make command line options compatible with GNU msgfmt
where they overlap.
Closes patch #101295.
