Tim Peters 26991a7f77 SF [#463737] Add types.CallableIterType
Rather than add umpteen new obscure internal Iter types, got rid of all of
them.  See the new comment.
2001-09-25 22:02:03 +00:00
Barry Warsaw 45653503ec test_iterator(): Don't do a type comparison to see if it's an
iterator, just test to make sure it has the two required iterator
protocol methods __iter__() and next() -- actually just test
hasattr-ness.
2001-09-25 21:40:04 +00:00
Fred Drake cc91ac09ef Factor out the protect-from-exceptions helpers and make capture_events()
use it.  This simplifies the individual tests a little.

Added some new tests related to exception handling.

Tim Peters 8dee809410 Guido points out that sys.__stdout__ is a bit bucket under IDLE. So keep
the local save/modify/restore of sys.stdout, but add machinery so that
regrtest can tell test_support the value of sys.stdout at the time
regrtest.main() started, and test_support can pass that out later to anyone
who needs a "visible" stdout.
2001-09-25 20:05:11 +00:00
Guido van Rossum 698acf98fd _reconstructor(): there's no need for tricks with assignment to
__class__.  The __new__ protocol is up to this.  (Thanks to Tim for
pointing this out.)
2001-09-25 19:46:05 +00:00
Tim Peters d48004f4f0 test_support should be imported directly, not via test.test_support. 2001-09-25 19:29:35 +00:00
Tim Peters 342ca75d95 Get rid of the increasingly convoluted global tricks w/ sys.stdout, in
favor of local save/modify/restore.  The test suite should run fine again.
2001-09-25 19:13:20 +00:00
Guido van Rossum 3926a63d05 - Provisional support for pickling new-style objects. (*)
- Made cls.__module__ writable.

- Ensure that obj.__dict__ is returned as {}, not None, even upon first
  reference; it simply springs into life when you ask for it.

(*) The pickling support is provisional for the following reasons:

- It doesn't support classes with __slots__.

- It relies on additional support in copy_reg.py: the C method
  __reduce__, defined in the object class, really calls calling
  copy_reg._reduce(obj).  Eventually the Python code in copy_reg.py
  needs to be migrated to C, but I'd like to experiment with the
  Python implementation first.  The _reduce() code also relies on an
  additional helper function, _reconstructor(), defined in
  copy_reg.py; this should also be reimplemented in C.
2001-09-25 16:25:58 +00:00
Guido van Rossum ad39aba2f6 Set sys.save_stdout (to sys.stdout), so doctest-using tests can be run
standalone.
2001-09-25 16:21:39 +00:00
Tim Peters f33532cfef + Display property functions in the same order they're specified to
property() (get, set, del; not set, get, del).

+ Change "Data defined/inherited in ..." header lines to
  "Data and non-method functions defined/inherited in ...".  Things like
  the value of __class__, and __new__, and class vrbls like the i in
      class C:
          i = int
  show up in this section too.  I don't think it's worth a separate
  section to distinguish them from non-callable attrs, and there's no
  obvious reliable way to distinguish callable from non-callable attrs
  anyway.
2001-09-25 06:30:51 +00:00
Guido van Rossum a4cb78874c Change repr() of a new-style class to say <class 'ClassName'> rather
than <type 'ClassName'>.  Exception: if it's a built-in type or an
extension type, continue to call it <type 'ClassName>.  Call me a
wimp, but I don't want to break more user code than necessary.
2001-09-25 03:56:29 +00:00
Guido van Rossum 5c294fb0e6 Make __class__ assignment possible, when the object structures are the
same.  I hope the test for structural equivalence is stringent enough.
It only allows the assignment if the old and new types:

- have the same basic size
- have the same item size
- have the same dict offset
- have the same weaklist offset
- have the same GC flag bit
- have a common base that is the same except for maybe the dict and
  weaklist (which may have been added separately at the same offsets
  in both types)
2001-09-25 03:43:42 +00:00
Tim Peters 2306d246e8 + Got rid of all instances of <small>. Under IE5, GUI-mode pydoc has
always been close to useless, because the <small>-ified docstrings
  were too small to read, even after cranking up my default font size
  just for pydoc.  Now it reads fine under my defaults (as does most
  of the web <0.5 wink>).  If it's thought important to play tricks
  with font size, tough, then someone should rework pydoc to use style
  sheets, and (more) predictable percentage-of-default size controls.

+ Tried to ensure that all <dt> and <dd> tags are closed.  I've read (but
  don't know) that some browsers get confused if they're not, and esp.
  when style sheets are in use too.
2001-09-25 03:18:32 +00:00
Tim Peters 3e767d19e0 GUI mode now displays useful stuff for properties. This is usually better
than text mode, since here we can hyperlink from the getter etc methods
back to their definitions.
2001-09-25 00:01:06 +00:00
Tim Peters f4aad8eb28 + Text-mode (but not yet GUI mode) pydoc now produces useful stuff for
properties:  the docstring (if any) is displayed, and the getter, setter
  and deleter (if any) functions are named.  All that is shown indented
  after the property name.

+ Text-mode pydoc class display now draws a horizontal line between
  class attribute groups (similar to GUI mode -- while visually more
  intrusive in text mode, it's still an improvement).
2001-09-24 22:40:47 +00:00
Tim Peters 66c1a525e0 Make properties discoverable from Python:
- property() now takes 4 keyword arguments:  fget, fset, fdel, doc.
  Note that the real purpose of the 'f' prefix is to make fdel fit in
  ('del' is a keyword, so can't used as a keyword argument name).

- These map to visible readonly attributes 'fget', 'fset', 'fdel',
  and '__doc__' in the property object.

- fget/fset/fdel weren't discoverable from Python before.

- __doc__ is new, and allows to associate a docstring with a property.
2001-09-24 21:17:50 +00:00
Fred Drake 30c4849169 Added several new tests to check the behavior with respect to doctype
declarations and weird markup that we used to accept & ignore that recent
versions raised an exception for; the original behavior has been restored
and augmented (the user can decide what to do if they care; the default is
to ignore it as done in early versions).
2001-09-24 20:22:09 +00:00
Fred Drake e822049efc Adapt to use the test_main() approach. 2001-09-24 20:19:08 +00:00
Fred Drake a3bae3369c Re-factor the SGMLParser class to use the new markupbase.ParserBase class.
Use a new internal method, error(), consistently to raise parse errors;
the new base class also uses this.
Adjust the parse_comment() method to return the new offset into the buffer
instead of the number of characters scanned; this was the only helper
method that did it this way, so we have better consistency now.  Required
to share the new base class.
This fixes SF bug #448482 and #453706.
2001-09-24 20:15:51 +00:00
Fred Drake bfc8fea1e0 Re-factor the HTMLParser class to use the new markupbase.ParserBase class.
Use a new internal method, error(), consistently to raise parse errors;
the new base class also uses this.
2001-09-24 20:10:28 +00:00
Fred Drake 1cffd5ccff Be consistent about the string module. 2001-09-24 20:04:29 +00:00
Fred Drake 68f8a8061d New base class for the SGMLParser and HTMLParser classes from the sgmllib
and HTMLParser modules (and indirectly for the htmllib.HTMLParser class).

This has all the support for scanning over DOCTYPE declarations; it warrants
having a base class since this is a fair amount of tedious code (since it's
fairly strict), and should be in a separate module to avoid compiling many
REs that are not used (which would happen if this were placed in either then
sgmllib or HTMLParser module).
2001-09-24 20:01:28 +00:00
Guido van Rossum 3d45d8f12e Another comparison patch-up: comparing a type with a dynamic metatype
to one with a static metatype raised an obscure error.
2001-09-24 18:47:40 +00:00
Fred Drake 2d879017b3 Add more tests showing the relationship between exceptions raised & caught
and the information provided to the profiler.  This stuff is a mess!
2001-09-24 18:44:11 +00:00
Guido van Rossum 2205642fe0 Do the same thing to complex that I did to str: the rich comparison
function returns NotImplemented when comparing objects whose
tp_richcompare slot is not itself.
2001-09-24 17:52:04 +00:00
Marc-André Lemburg e47df7a211 StringIO patch #462596: let's [c]StringIO accept read buffers on
input to .write() too.
2001-09-24 17:34:52 +00:00
Guido van Rossum bb77e6801e Change string comparison so that it applies even when one (or both)
arguments are subclasses of str, as long as they don't override rich
comparison.
2001-09-24 16:51:54 +00:00
Guido van Rossum ff0e6d6ef5 Fix the baffler that Tim reported: sometimes the repr() of an object
looks like <X object at ...>, sometimes it says <X instance at ...>.
Make this uniformly say <X object at ...>.

Steven M. Gava c11ccf35f4 start of new config handling stuff 2001-09-24 09:43:17 +00:00
Tim Peters fa26f7cc39 More work on class display:
+ Minor code cleanup, generalization and simplification.

+ "Do something" to make the attribute aggregation more apparent:
    - In text mode, stick a "* " at the front of subgroup header lines.
    - In GUI mode, display a horizontal rule between subgroups.
   For GUI mode, this is a huge improvement, at least under IE.
2001-09-24 08:05:11 +00:00
Tim Peters b47879b239 Try to do for pydoc's GUI mode what the earlier checkin did for text
mode (identify the source class for class attrs; segregate attrs according
to source class, and whether class method, static method, property, plain
method, or data; display data attrs; display docstrings for data attrs
when possible).

Alas, this is mondo ugly, and I'm no HTML guy.  Part of the problem is
that pydoc's GUI mode has always been ugly under IE, largely because
<small> under IE renders docstrings unreadably small (while sometimes
non-docstring text is painfully large).  Another part is that these
segregated listings of attrs would *probably* look much better as bulleted
lists.  Alas, when I tried that, the bullets all ended up on lines by
themselves, before the method names; this is apparently because pydoc
(ab?)uses definition lists for format effects, and at least under IE
if a definition list is the first chunk of a list item, it gets rendered
on a line after the <li> bullet.

An HTML wizard would certainly be welcomed here.
2001-09-24 04:47:19 +00:00
Tim Peters 28355496c1 Part of a partial solution to SF bugs 463378, 463381, 463383, 463384.
This almost entirely replaces how pydoc pumps out class docs, but only
in text mode (like help(whatever) from a Python shell), not in GUI mode.

A class C's attrs are now grouped by the class in which they're defined,
attrs defined by C first, then inherited attrs grouped by alphabetic order
of the defining classes' names.

Within each of those groups, the attrs are subgrouped according to whether
they're plain methods, class methods, static methods, properties, or data.
Note that pydoc never dumped class data attrs before.  If a class data
attr is implemented via a data descriptor, the data docstring (if any)
is also displayed (e.g., file.softspace).

Within a subgroup, the attrs are listed alphabetically.

This is a friggin' mess, and there are bound to be glitches.  Please
beat on it and complain!  Here are three glitches:

1. __new__ gets classifed as 'data', for some reason.  This will
   have to get fixed in inspect.py, but since the latter is already
   looking for any clue that something is a method, pydoc will
   almost certainly not know what to do with it when its classification
   changes.

2. properties are special-cased to death.  Unlike any other kind of
   function or method, they don't have a __name__ attr, so none of
   pydoc's usual code can deal with them.  Worse, the getter and
   setter and del'er methods associated with a property don't appear
   to be discoverable from Python, so there's really nothing I can
   think of to do here beyond just listing their names.

   Note that a property can't be given a docstring, either (or at least
   I've been unable to sneak one in) -- perhaps the property()
   constructor could take an optional doc argument?

3. In a nested-scopes world, pydoc still doesn't know anything about
   nesting, so e.g. classes nested in functions are effectively invisible.

Barry Warsaw d31db7e939 The test data (mostly example messages) for the email package test
suite.  Note that other tests can put input data in this directory.

Barry Warsaw 4107585a67 An extensive test suite for the email package. 2001-09-23 03:18:13 +00:00
Barry Warsaw ba92580f01 The email package version 1.0, prototyped as mimelib
<http://sf.net/projects/mimelib>.  There /are/ API differences between
mimelib and email, but most of the implementations are shared (except
where cool Py2.2 stuff like generators are used).
2001-09-23 03:17:28 +00:00
Tim Peters 13b49d3374 New function classify_class_attrs(). As a number of SF bug reports
point out, pydoc doesn't tell you where class attributes were defined,
gets several new 2.2 features wrong, and isn't aware of some new features
checked in on Thursday <wink>.  pydoc is hampered in part because
inspect.py has the same limitations.  Alas, I can't think of a way to
fix this within the current architecture of inspect/pydoc:  it's simply
not possible in 2.2 to figure out everything needed just from examining
the object you get back from class.attr.  You also need the class
context, and the method resolution order, and tests against various things
that simply didn't exist before.  OTOH, knowledge of how to do that is
getting quite complex, so doesn't belong in pydoc.

classify_class_attrs takes a different approach, analyzing all
the class attrs "at once", and returning the most interesting stuff for
each, all in one gulp.  pydoc needs to be reworked to use this for
classes (instead of the current "filter dir(class) umpteen times against
assorted predicates" approach).
2001-09-23 02:00:29 +00:00
Tim Peters 8a9c284437 Make difflib.ndiff() and difflib.Differ.compare() generators. This
restores the 2.1 ability of Tools/scripts/ndiff.py to start producing
output before the entire comparison is complete.
2001-09-22 21:30:22 +00:00
Tim Peters e0b2d7ac9a Add a function to compute a class's method resolution order. This is
easy for 2.2 new-style classes, but trickier for classic classes, and
different approaches are needed "depending".  The function will allow
later code to treat all flavors of classes uniformly.
2001-09-22 06:10:55 +00:00
Tim Peters c377b16d12 Since the most likely failure mode for an expected-output test is a change
somewhere inside a line, use ndiff so that intraline difference marking
can point out what changed within a line.  I don't remember diff-style
abbreviations either (haven't used it since '94, except to produce
patches), so say the rest in English too.
2001-09-22 05:31:03 +00:00
Barry Warsaw bdefa0b3de __iter__(): New method so that StringIO's can participate in the
iterator protocol.
2001-09-22 04:34:54 +00:00
Barry Warsaw 7f8ff471f8 Converted test_StringIO.py to use unittest, so
Lib/test/output/test_StringIO is no longer necessary.

Also, added a test of the iterator protocol that's just been added to
StringIO's and cStringIO's.
2001-09-22 04:33:47 +00:00
Fred Drake 3208d4b387 Start of a test to make sure the profiler/tracer support in the core
interpreter is reporting what we expect to see.
2001-09-22 04:28:19 +00:00
Guido van Rossum 19c1cd5b35 Add the __getattr__ hook back. The rules are now:
- if __getattribute__ exists, it is called first;
  if it doesn't exists, PyObject_GenericGetAttr is called first.
- if the above raises AttributeError, and __getattr__ exists,
  it is called.
2001-09-21 21:24:49 +00:00
Guido van Rossum cf691935bb reportdiff(): print a "plain diff" style diff.
XXX This should really be a unified diff, but I can't be bothered.
2001-09-21 21:06:22 +00:00
Guido van Rossum 0a07639779 Oops. I didn't expect that some tests (test_cookie) have expected
output *and* doctest stuff.  Assuming the doctest stuff comes after the
expected output, this fixes that.
2001-09-21 20:45:44 +00:00
Guido van Rossum 0fcca4e815 Change the way unexpected output is reported: rather than stopping at
the first difference, let the test run till completion, then gather
all the output and compare it to the expected output using difflib.

XXX Still to do: produce diff output that only shows the sections that
differ; currently it produces ndiff-style output because that's the
easiest to produce with difflib, but this becomes a liability when the
output is voluminous and there are only a few differences.
2001-09-21 20:31:52 +00:00
Guido van Rossum 867a8d2e26 Change the name of the __getattr__ special method for new-style
classes to __getattribute__, to make it crystal-clear that it doesn't
have the same semantics as overriding __getattr__ on classic classes.

This is a halfway checkin -- I'll proceed to add a __getattr__ hook
that works the way it works in classic classes.

Marc-André Lemburg 6871f6ac57 Implement the changes proposed in patch #413333. unicode(obj) now

2001-09-20 06:30:41 +00:00
Tim Peters 4bcfa317ee Since inspect.isfunction(obj) is a precondition for calling
inspect.getargspec(obj), test isfunction() directly in pydoc.py instead
of trying to indirectly deduce isfunction() in pydoc by virtue of
failing a combination of other tests.  This shouldn't have any visible
effect, except perhaps to squash a TypeError death if there was some path
thru this code that was inferring isfunction() by mistake.
2001-09-20 06:08:24 +00:00
Tim Peters f1d90b965e Ensure that isfunction(obj) and (the new) ismethoddescriptor(obj) never
both return true.  This restores pydoc's ability to deduce argument lists
for functions and methods coded in Python.
2001-09-20 05:47:55 +00:00
Tim Peters 536d2262f7 After much thrashing, I believe this is a truly minimal patch to teach
pydoc how to do something sensible with 2.2 descriptors.  To see the
difference, browse __builtin__ via pydoc before and after the patch.

Guido van Rossum 1952e388ca Add additional coercion support for "self subtypes" to int, long,

2001-09-19 01:25:16 +00:00
Guido van Rossum d5d8e4a436 Enable two checks for comparing a complex to a complex subtype
instance.

Split a string comparison test in two halves, replacing "a==b==a" with
separate tests for a==b and b==a.  (Reason: while experimenting, this
test failed, and I wanted to know if it was the first or the second ==
operator that failed.)
2001-09-19 01:16:16 +00:00

2001-09-18 20:55:24 +00:00
Guido van Rossum ab3b0343b8 Hopefully fix 3-way comparisons. This unfortunately adds yet another
hack, and it's even more disgusting than a PyInstance_Check() call.
If the tp_compare slot is the slot used for overrides in Python,
it's always called.

Add some tests that show what should work too.

#462270: sub-tle difference between pre.sub and sre.sub.  PRE ignored
an empty match at the previous location, SRE didn't.

also synced with Secret Labs "sreopen" codebase.

Guido van Rossum 912e56c3ac SF bug #417176 (Martijn Pieters): MultiFile.read() includes CRLF
boundary.

Fixed by keeping a readahead buffer containing the next line.

XXX We have no test suite for this.  Maybe the new email package will
help?

Guido van Rossum 555d12f986 softspace(): be prepared to catch AttributeError as well as TypeError
upon attempted attribute assignment.  Caught by MWH, SF bug #462522.
2001-09-18 13:33:01 +00:00
Tim Peters 22cd768177 This module didn't work at all anymore -- blew up with AttributeError
on file.__methods__.  Since the docs say "This module will become obsolete
in a future release", this is just a quick hack to stop it from blowing
up.  If you care about this module, test it!  It doesn't make much sense
on Windows.

Guido van Rossum db2a902dee Undo some (but not all) of the more lenient acceptance of
(AttributeError, TypeError) -- the leniency wasn't needed everywhere.
2001-09-18 03:55:22 +00:00
Guido van Rossum bd13149711 - Some tests that check that assignments are not allowed expect this
to raise TypeError.  In practice, a disallowed attribute assignment
  can raise either TypeError or AttributeError (and it's unclear which
  is better).  So allow either.  (Yes, this is in anticipation of a
  code change that switches the exception raised. :-)

- Add a utility function, cantset(), which verifies that setting a
  particular attribute to a given value is disallowed, and also that
  deleting that same attribute is disallowed.  Use this in the
  test_func_*() tests.

- Add a new set of tests that test conformance of various instance
  method attributes.  (Also in anticipation of code that changes their
  implementation.)

Guido van Rossum d9d1d4ac6f Rewrite function attributes to use the generic routines properly.

Jeremy Hylton 9dca36432e API change:
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.

Jeremy Hylton 2e4cc7e0d8 Last set of change to get regression tests to pass
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
2001-09-17 19:33:48 +00:00
Jeremy Hylton 37c9351cf6 Handle more syntax errors.
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.

Guido van Rossum 83eeef4b06 SF patch #461781 by Chris Lawrence: os.path.realpath - Resolve symlinks:
Once upon a time, I put together a little function
   that tries to find the canonical filename for a given
   pathname on POSIX. I've finally gotten around to
   turning it into a proper patch with documentation.
   On non-POSIX, I made it an alias for 'abspath', as
   that's the behavior on POSIX when no symlinks are
   encountered in the path.

   Example:
   >>> os.path.realpath('/usr/bin/X11/X')
   '/usr/X11R6/bin/X'

Tim Peters 305b5857f6 PyObject_Dir(): Merge in __members__ and __methods__ too (if they exist,
and are lists, and then just the string elements (if any)).

There are good and bad reasons for this.  The good reason is to support
dir() "like before" on objects of extension types that haven't migrated
to the class introspection API yet.  The bad reason is that Python's own
method objects are such a type, and this is the quickest way to get their
im_self etc attrs to "show up" via dir().  It looks much messier to move
them to the new scheme, as their current getattr implementation presents
a view of their attrs that's a untion of their own attrs plus their
im_func's attrs.  In particular, methodobject.__dict__ actually returns
methodobject.im_func.__dict__, and if that's important to preserve it
doesn't seem to fit the class introspection model at all.

wasn't intended to get checked in.
