Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
alias file); the encoding lookup was enhanced to use Python's
encoding alias table
As sige-effect, this fixes SF bug [ 1080864 ] locale.py doesn't recognize
valid locale setting.
SF patch #1015989
The basic idea of this patch is to compute lineno attributes for all AST nodes. The actual
implementation lead to a lot of restructing and code cleanup.
The generated AST nodes now have an optional lineno argument to constructor. Remove the
top-level asList(), since it didn't seem to serve any purpose. Add an __iter__ to ast nodes.
Use isinstance() instead of explicit type tests.
Change transformer to use the new lineno attribute, which replaces three lines of code with one.
Use universal newlines so that we can get rid of special-case code for line endings. Use
lookup_node() in a few more frequently called, but simple com_xxx methods(). Change string
exception to class exception.
unicodedata.east_asian_width(). You can still implement your own
simple width() function using it like this:
def width(u):
w = 0
for c in unicodedata.normalize('NFC', u):
cwidth = unicodedata.east_asian_width(c)
if cwidth in ('W', 'F'): w += 2
else: w += 1
return w
The script was originally used to create the initial set of
codecs (and these were (c) CNRI). While the script itself still
is (c) CNRI, the output certainly isn't anymore.
iswide() for east asian width manipulation. (Inspired by David
Goodger, Reviewed by Martin v. Loewis)
- Move _PyUnicode_TypeRecord.flags to the end of the struct so that
no padding is added for UCS-4 builds. (Suggested by Martin v. Loewis)
(Code contributed by Jiwon Seo.)
The documentation portion of the patch is being re-worked and will be
checked-in soon. Likewise, PEP 289 will be updated to reflect Guido's
rationale for the design decisions on binding behavior (as described in
in his patch comments and in discussions on python-dev).
The test file, test_genexps.py, is written in doctest format and is
meant to exercise all aspects of the the patch. Further additions are
welcome from everyone. Please stress test this new feature as much as
possible before the alpha release.

Backport candidate.
* Delimiter mismatch now prints a warning instead of raising an exception.
* Offer style warnings for use of e.g. and i.e.
* Bypass false positive warnings for forward slashes in urls and in /rfc822.
* Put non-LaTex delimiter matching first to make -d option more reliable.
* Added more LaTex cmds from the docs.
* Blocked forward-slash warnings with delimiters-only option.
* Put help message on shorter line to fit an 80 char screen.
I'm finding some pretty baffling output, like reprs consisting entirely
of three left parens. At least this will let us know what type the object
is (it's not str -- there's no quote character in the repr).
New tool combinerefs.py, to combine the two output blocks produced via
PYTHONDUMPREFS.
The Py2.3 updates to the pyclbr module return both Class and Function
objects. The IDLE ClassBrowser module only knew about Class and could
not handle objects which did not define "super".
Fixed by adding a guard.
externally visible name of the module. This is so that type names can be
shown as "Carbon.File.FSSpec" even though the real name of the module is
"_File".
The bug is a reference to co_first_lineno that should be
co_firstlineno. The only other substantial change is to speed up
localtrace_count() by avoiding *costly* calls to inspect module.
It's trivial to get the filename and lineno directly from the frame.
Otherwise, delete commented out debug code and reflow very long lines.
Mark writes in private email:
"Modules listed in the registry was a dumb idea. This whole scheme
can die. AFAIK, no one in the world uses it (including win32all
since the last build)."
(See also SF #643711)
per PEP 291 (although there are currently string methods used).
This patch makes it compatible with 2.2, at least, by detecting
universal newline support.
get PEP-252 style objects in stead of old-fashioned objects.
In stead of defining a GetattrHook you declare a class variable getsetlist,
which contains tuples (name, getcode, setcode, docstring).
Only lightly tested: the code still works if you don't inherit PEP252Mixin
and the code works if you inherit it but don't define any getters
or setters. Also, this will not work together with the "poor mans inheritance"
offered by method chains, so the CF module will remain with old-style
objects until PEP253 is supported too.
contains options, drop them to get the major/minor content type.
Modified from the supplied patch to support more whitespace variation.
Closes SF patch #613605.
build(): Fix the logic here for calculating fallbacks if the dbfile
isn't parseable.
main(): Fix the semantics for -d/--database; this should override any
database value found in the .pynche file.
Update some comments, and author contact info.
Bump to v1.4
Whitespace normalization.
(with one small bugfix in bgen/bgen/scantools.py)
This replaces string module functions with string methods
for the stuff in the Tools directory. Several uses of
string.letters etc. are still remaining.
[ 587993 ] SET_LINENO killer
Remove SET_LINENO. Tracing is now supported by inspecting co_lnotab.
Many sundry changes to document and adapt to this change.
where it was: it is really a configuration file, not a normal module.
By moving it into Mac/Lib we can now also store the location of bgen
itself in there, which is needed because bgen isn't installed.
* globaltrace_lt - handle case where inspect.getmodulename doesn't return
anything useful
* localtrace_trace - handle case where inspect.getframeinfo doesn't return
any context info
I think both of the last two are caused by exec'd or eval'd code
defined and the default was "pre" instead of "sre". Give up on 1.5.2
compatibility, hardcode the sre solution. However, this XXX comment
still applies, AFAIK:
# XXX This code depends on internals of the regular expression
# engine! There's no standard API to do a substitution when you
# have already found the match. One should be added.
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure. Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers. (In
fact, we expect that the compilers are all fixed eight years later.)
I'm leaving staticforward and statichere defined in object.h as
static. This is only for backwards compatibility with C extensions
that might still use it.
XXX I haven't updated the documentation.
1. BUGFIX: In function makefile(), strip blanks from the nodename.
This is necesary to match the behavior of parser.makeref() and
parser.do_node().
2. BUGFIX fixed KeyError in end_ifset (well, I may have just made
it go away, rather than fix it)
3. BUGFIX allow @menu and menu items inside @ifset or @ifclear
4. Support added for:
@uref URL reference
@image image file reference (see note below)
@multitable output an HTML table
@vtable
5. Partial support for accents, to match MAKEINFO output
6. I added a new command-line option, '-H basename', to specify
HTML Help output. This will cause three files to be created
in the current directory:
`basename`.hhp HTML Help Workshop project file
`basename`.hhc Contents file for the project
`basename`.hhk Index file for the project
When fed into HTML Help Workshop, the resulting file will be
named `basename`.chm.
7. A new class, HTMLHelp, to accomplish item 6.
8. Various calls to HTMLHelp functions.
A NOTE ON IMAGES: Just as 'outputdirectory' must exist before
running this program, all referenced images must already exist
in outputdirectory.
FLD: wrapped some long lines.
Not sure this is better in all cases.
parse(): Fixed a bug in the output; the dict is referred to in the
code as `countries' not `country'. Also added no-case-fold for the
string "U.S." since the Virgin Islands name no longer wraps those in
parentheses.
main(): Fixed the argument parsing to agree with the docstring, i.e.
--outputdict instead of --output.
In the module docstring:
- updated my email address
- we don't need to explain about Python 1.5 regexps <wink>
We also don't need to wrap the import of re with a try/except.
Other style fixes:
- untabification
- revert back to <> style everywhere (and consistently)
This patch replaces string module functions with string
methods in the Tools/world/world scripts.
It also updates two outdated URLs and the countrycodes
dictionary.
It fixes a bug where result of string.find() was checked
for truth instead of compared with -1.
It also replaces <> with != in two spots.
Assorted crashes on Windows and Linux when trying to display a very
long calltip, most likely a Tk bug. Wormed around by clamping the
calltip display to a maximum of 79 characters (why 79? why not ...).
Bugfix candidate, for all Python releases.
pymalloc, apparently. Fixed, but this means all bgen-generated modules will
have to be re-generated.
I hope (and expect) that the pymalloc fixes aren't bugfix candidates, because
if they are this is one too.
The problem was that an exception can occur in the text.get() call or
in the write() call, when the text buffer contains non-ASCII
characters. This causes the previous contents of the file to be lost.
The provisional fix is to call str(self.text.get(...)) *before*
opening the file, so that if the exception occurs, we never open the
file.
Two orthogonal better solutions have to wait for policy decisions:
1. We could try to encode the data as Latin-1 or as UTF-8; but that
would require IDLE to grow a notion of file encoding which requires
more thought.
2. We could make backups before overwriting a file. This requires
more thought because it needs to be fast and cross-platform and
configurable.
The cause seems to be that when a file URL doesn't exist,
urllib.urlopen() raises OSError instead of IOError. Simply add this
to the except clause. Not elegant, but effective. :-)
(With slight cosmetic improvements to shorten lines and a grammar fix
to a docstring.)
This addes -X and -E options to freeze. From the docstring:
-X module Like -x, except the module can never be imported by
the frozen binary.
-E: Freeze will fail if any modules can't be found (that
were not excluded using -x or -X).
The strerror attribute contained only partial information about the
exception and produced some very confusing error messages. By passing
err (the exception object itself) and letting it convert itself to a
string, the error messages are better.
compile() becomes replacement for builtin compile()
compileFile() generates a .pyc from a .py
both are exported in __init__
compiler.parse() gets optional second argument to specify compilation
mode, e.g. single, eval, exec
Add AbstractCompileMode as parent class and Module, Expression, and
Interactive as concrete subclasses. Each corresponds to a compilation
mode.
THe AbstractCompileMode instances in turn delegate to CodeGeneration
subclasses specialized for their particular functions --
ModuleCodeGenerator, ExpressionCodeGeneration,
InteractiveCodeGenerator.
The argument properties are ordered from easiest to hardest. The
harder the arg, the more complicated that code that must be generated
to return it from getChildren() and/or getChildNodes(). The old
calculation routine was bogus, because it always set hardest_arg to
the hardness of the last argument. Now use max() to always set it to
the hardness of the hardest argument.
Remove the only test in the syntax module. It ends up that the
transformer must handle this error case.
In the transformer, check for a list compression in com_assign_list()
by looking for a list_for node where a comma is expected.
In pycodegen.compile() re-raise the SyntaxError rather than catching
it and exiting
Invoke compiler.syntax.check() after building AST. If a SyntaxError
occurs, print the error and exit without generating a .pyc file.
Refactor code to use compiler.misc.set_filename() rather than passing
filename argument around to each CodeGenerator instance.
introspection incompatibility, but in fact it's just that calltips
always gave up on a docstring that started with a newline (but
didn't realize they were giving up <wink>).
Remove the option to have nested scopes or old LGB scopes. This has a
large impact on the code base, by removing the need for two variants
of each CodeGenerator.
Add a get_module() method to CodeGenerator objects, used to get the
future features for the current module.
Set CO_GENERATOR, CO_GENERATOR_ALLOWED, and CO_FUTURE_DIVISION flags
as appropriate.
Attempt to fix the value of nlocals in newCodeObject(), assuming that
nlocals is 0 if CO_NEWLOCALS is not defined.
operators per line or statement are now on by default, and -m turns
these warnings off.
- Change the way multiple / operators are reported; a regular
recommendation is always emitted after the warning.
- Report ambiguous warnings (both int|long and float|complex used for
the same operator).
- Update the doc string again to clarify all this and describe the
possible messages more precisely.
percolated out, and some general cleanup. The output is still the
same, except it now prints "Index: <file>" instead of "Processing:
<file>", so that the output can be used as input for patch (but only
the diff-style parts of it).
Fix list comp code generation -- emit GET_ITER instead of Const(0)
after the list.
Add CO_GENERATOR flag to generators.
Get CO_xxx flags from the new module
try/except or try/finally.
Previous versions had only track SETUP_LOOP blocks and ignored the
exception part. This meant that it allowed continue inside a
try/except but generated buggy code. Now it does the right thing.
As the doc string for _lookupName() explains:
This routine uses a list instead of a dictionary, because a
dictionary can't store two different keys if the keys have the
same value but different types, e.g. 2 and 2L. The compiler
must treat these two separately, so it does an explicit type
comparison before comparing the values.
Avoid if/elif/elif/else tests where the final else is supposed to
handle exactly one case instead of all other cases. When the list of
operators is extended, the catchall else treats all new operators as
the last operator in the set of tests. Instead, raise an exception if
an unexpected operator occurs.
Use a dictionary instead of a list to map objects to their offsets in
a const/name tuple of a code object.
XXX The conversion is perhaps incomplete, in that we shouldn't have to
do the list2dict to start.
Add support for floor division (// and //=)
The implementation of getChildren() and getChildNodes() is intended to
be faster, because it avoids calling flatten() on every return value.
But it's not clear that it is a lot faster, because constructing a
tuple with just the right values ends up being slow. (Too many
attribute lookups probably.)
The ast.txt file is much more complicated, with funny characters at
the ends of names (*, &, !) to indicate the types of each child node.
The astgen script is also much more complex, making me wonder if it's
still useful.
varnames should list all the local variables (with arguments first).
The XXX_NAME ops typically occur at the module level and assignment
ops should create locals.
(Hard to believe these were never handled before)
Add misc.mangle() that mangles based on the rules in compile.c.
XXX Need to test the corner cases
Update CodeGenerator with a class_name attribute bound to None. If a
particular instance is created within a class scope, the instance's
class_name is bound to that class's name.
Add mangle() method to CodeGenerator that mangles if the class_name
has a class_name in it.
Modify the FunctionCodeGenerator family to handle an extra argument--
the class_name.
Wrap all name ops and attrnames in calls to self.mangle()
Make nested scopes enabled by default
Add is_constant_false() helper so that compiled code and symbols are
consistent with builtin compiler's handling of "if 0:"
Fix doc string handling to be consistent with recent change that
eliminates the doc string from the Module's node attribute.
Add fix to print handling from Evan & Shane.
Track change to visitor api by making "verbose" explicit.
Comment out setting CO_NESTED flag (it's unnecessary in 2.2).
Evan Simpson's fix. And his explanation:
If you defined two nested functions in a row that refer to the
same non-global variable, the second one will be generated as
though the variable were global.
The use of com_node() introduces a lot of extra stack frames, enough
to cause a stack overflow compiling test.test_parser with the standard
interpreter recursionlimit. The com_node() is a convenience function
that hides the dispatch details, but comes at a very high cost. It is
more efficient to dispatch directly in the callers. In these cases,
use lookup_node() and call the dispatched node directly.
Also handle yield_stmt in a way that will work with Python 2.1
(suggested by Shane Hathaway)
Remove _preorder as alias for dispatch and call dispatch directly.
Add an extra optional argument to walk()
XXX Also comment out some code that does debugging prints.
The tests are run from a copy of the library directory, where
everything has been compiled by the compiler package.
Add a raw_input() call at the end of the script, so that I can check
the output before the temp directory with the compiled code is
removed.
- make the selftests work again (they were apparently not used since
very early in bgen's development), with some minor cleanup by me
- make emacs python mode happier
ChipWidget.__init__(): Added a message area just below the color
name. Both the message and name widgets are now FLAT, DISABLED
Entry widgets instead of Labels. This allows users to
copy-n-paste the color names or color specs. Also, the contents
of both widgets are now driven by StringVars.
set_color(): This only sets the chip color; it does not set the name
widgets.
set_name(): New method which only sets the name widget contents.
set_message(): New method which only sets the message widget contents.
ChipViewer.update_yourself(): Set the color, name, and message for
each chip as follows: the first line always contains the color
spec in #rrggbb format. The second line will contain the color
name, but slightly differently for each widget. For the Selected
widget, if the color exactly matches the Nearest color, the name
is shown, otherwise the message field will be empty. The name
field of the Nearest widget will always contain the color name.
Change several sections to subsections (part of the manual -> howto
transformation).
Flesh out discussion of assignment nodes (and delete statements).
Add an example of manipulating AST objects at a >>> prompt
Remove the module index; there aren't enough modules documented yet
for this to make sense.
Add a couple more index entries, fixed a few typos, and adjusted a few
more things for consistency.
Cater to that.
+ Major speed boost via not reading more of files than necessary. This
was no slouch before; now it screams.
+ Improve msg when giving up on a goofy future statement.
If multiple header files are processed simultaneously which include each
other, the corresponding modules mport each other. Specifically, if h2py
is invoked with sys/types.h first, later header files won't contain the
complete contents of TYPES.py.
list of files to not extract docstrings from when the -D option is
given. This isn't optimal, but I didn't want to change the semantics
of -D, and it's bad form to allow optional switch arguments.
Bumping __version__ to 1.4.
TokenEater.__init__(): Initialize __curfile to None.
__waiting(): In order to extract docstrings from the module, both the
-D flag should be set, and the __curfile should not be named in
the -X filename (i.e. it isn't in opts.nodocstrings).
set_filename(): Fixed a bug where once the first module docstring is
extracted, no subsequent module docstrings will be extracted. The
bug was that the first extraction set __freshmodule to 0, but that
flag was never reset back to 1. set_filename() is always called
when the next file is being processed, so use it to reset the
__freshmodule flag.
main(): Add support for -X/--no-docstring.
fragile. Now the leading "0x" on hex numbers are displayed as labels
and the type-in entry fields just accept the hex digits. Be sure to
strip off the "0x" string when displaying hex values too.
Also, de-string-module-ification, and other Python 2.x improvements.
found a bug here. Here's the deal:
Class PyShell derives from class OutputWindow. Method PyShell.close()
wants to invoke its parent method, but because PyShell long ago was
inherited from class PyShellEditorWindow, it invokes
PyShelEditorWindow.close(self). Now, class PyShellEditorWindow itself
derives from class OutputWindow, and inherits the close() method from
there without overriding it. Under the old rules,
PyShellEditorWindow.close would return an unbound method restricted to
the class that defined the implementation of close(), which was
OutputWindow.close. Under the new rules, the unbound method is
restricted to the class whose method was requested, that is
PyShellEditorWindow, and this was correctly trapped as an error.
This allows system libs to be weak-linked, thereby allowing us to generate functions that are only available on some OS versions without getting a NULL dereference if the function isn't available.
I published it on the web as http://www.python.org/2.1/md5sum.py
so I thought I might as well check it in.
Works with Python 1.5.2 and later.
Works like the Linux tool ``mdfsum file ...'' except it doesn't take
any options or read stdin.
Armin Rigo pointed out that the way the line-# table got built didn't work
for lines generating more than 255 bytes of bytecode. Fixed as he
suggested, plus corresponding changes to pyassem.py, plus added some
long overdue docs about this subtle table to compile.c.
Bugfix candidate (line numbers may be off in tracebacks under -O).
indicating whether the entry was extracted from a docstring or not.
write(): If any of the locations of a string appearance came from a
docstring, add a comment such as
#. docstring
before the references (after a suggestion by Martin von Loewis).
codec files to codecs.py and added logic so that multi mappings
in the decoding maps now result in mappings to None (undefined mapping)
in the encoding maps.
rather than the idle.py script. This has advantages and
disadvantages; the biggest advantage being that we can more easily
have an alternative main program.
Assertion error message had typos in arguments to string format.
.cover files for modules in packages are now put in the right place.
The code that generate .cover files seemed to prepend a "./" to many
absolute paths, causing them to fail. The code now checks explicitly
for absolute paths and leaves them alone.
In trace/coverage code, recover from case where module has no __name__
attribute, when e.g. it is executed by PyRun_String(). In this case,
assign modulename to None and hope for the best. There isn't anywhere
to write out coverage data for this code anyway.
Also, replace several sys.stderr.writes with print >> sys.stderr.
New features:
-C/--coverdir dir: Generate .cover files in specified directory
instead of in the directory where the .py file is.
-s: Print a short summary of files coverred (# lines, % coverage,
name)
variables reported by PyChecker.
__togglegentype(): PyChecker accurately reported that the variable
__gentypevar was unused -- actually this whole method is currently
unused so comment it out.
