Christian Heimes 082c9b0267 Fixed bug #1915: Python compiles with --enable-unicode=no again. However several extension methods and modules do not work without unicode support. 2008-01-23 14:20:50 +00:00
Brett Cannon fa6521b4fd Make the __import__ call in encodings.__init__ absolute with a level 0 call. 2007-02-16 19:33:01 +00:00
Brett Cannon 971a012ce1 Update the encoding package's search function to use absolute imports when
calling __import__.  This helps make the expected search locations for encoding
modules be more explicit.

One could use an explicit value for __path__ when making the call to __import__
to force the exact location searched for encodings.  This would give the most
strict search path possible if one is worried about malicious code being
imported.  The unfortunate side-effect of that is that if __path__ was modified
on 'encodings' on purpose in a safe way it would not be picked up in future
__import__ calls.

Georg Brandl a92979a1db Bug #1446043: correctly raise a LookupError if an encoding name given
to encodings.search_function() contains a dot.

Walter Dörwald abb02e5994 Patch #1436130: codecs.lookup() now returns a CodecInfo object (a subclass
of tuple) that provides incremental decoders and encoders (a way to use
stateful codecs without the stream API). Functions
codecs.getincrementaldecoder() and codecs.getincrementalencoder() have
been added.

Guido van Rossum 87de069e4e Use relative imports in a few places where I noticed the need.
(Ideally, all packages in Python 2.5 will use the relative import
syntax for all their relative import needs.)

Marc-André Lemburg fe4b34cc4b Fix the encodings package codec search function to only search
inside its own package. Fixes problem reported in patch #1433198.

Add codec search function for codec test codec.

Marc-André Lemburg c83dddf7fe Let the default encodings search function lookup aliases before trying the codec import. This allows applications to install codecs which override (non-special-cased) builtin codecs. 2004-01-20 09:40:14 +00:00

Tim Peters 6578dc925f Whitespace normalization. 2002-12-24 18:31:27 +00:00
Guido van Rossum c8c6065231 When looking for an alias, first look for the normalized name (which
still may contain dots), then if that doesn't exist look for the name
with dots replaced by underscores.  This is a little more forgiving.

Martin v. Löwis b9e0764d8b Revert #571603 since it is ok to import codecs that are not subdirectories
of encodings. Skip modules that don't have a getregentry function.

Martin v. Löwis fc4c24c142 Patch #571603: Refer to encodings package explicitly. 2002-07-28 11:31:33 +00:00
Marc-André Lemburg a0af63b242 Corrected import behaviour for codecs which live outside the encodings
package.

Marc-André Lemburg 462004e90a Add IANA character set aliases to the encodings alias dictionary
and make alias lookup lazy.

Note that only those IANA character set aliases were added for which
we actually have codecs in the encodings package.

Marc-André Lemburg 816a1b75b7 Fixed search function error reporting in the encodings package
__init__.py module to raise errors which can be catched as LookupErrors
as well as SystemErrors.

Modified the error messages to include more information about the
failing module.
2001-09-19 11:52:07 +00:00
Marc-André Lemburg 988ad2bdff Changed .getaliases() support to register the new aliases in the
encodings package aliases mapping dictionary rather than in the
internal cache used by the search function.

This enables aliases to take advantage of the full normalization
process applied to encoding names which was previously not available.

The patch restricts alias registration to new aliases. Existing
aliases cannot be overridden anymore.

Guido van Rossum 9e896b37c7 Marc-Andre's third try at this bulk patch seems to work (except that
his copy of test_contains.py seems to be broken -- the lines he
deleted were already absent).  Checkin messages:


New Unicode support for int(), float(), complex() and long().

- new APIs PyInt_FromUnicode() and PyLong_FromUnicode()
- added support for Unicode to PyFloat_FromString()
- new encoding API PyUnicode_EncodeDecimal() which converts
  Unicode to a decimal char* string (used in the above new
  APIs)
- shortcuts for calls like int(<int object>) and float(<float obj>)
- tests for all of the above

Unicode compares and contains checks:
- comparing Unicode and non-string types now works; TypeErrors
  are masked, all other errors such as ValueError during
  Unicode coercion are passed through (note that PyUnicode_Compare
  does not implement the masking -- PyObject_Compare does this)
- contains now works for non-string types too; TypeErrors are
  masked and 0 returned; all other errors are passed through

Better testing support for the standard codecs.

Misc minor enhancements, such as an alias dbcs for the mbcs codec.

Changes:
- PyLong_FromString() now applies the same error checks as
  does PyInt_FromString(): trailing garbage is reported
  as error and not longer silently ignored. The only characters
  which may be trailing the digits are 'L' and 'l' -- these
  are still silently ignored.
- string.ato?() now directly interface to int(), long() and
  float(). The error strings are now a little different, but
  the type still remains the same. These functions are now
  ready to get declared obsolete ;-)
- PyNumber_Int() now also does a check for embedded NULL chars
  in the input string; PyNumber_Long() already did this (and
  still does)

Followed by:

Looks like I've gone a step too far there... (and test_contains.py
seem to have a bug too).

I've changed back to reporting all errors in PyUnicode_Contains()
and added a few more test cases to test_contains.py (plus corrected
the join() NameError).

Attached you find an update of the Unicode implementation.

    The patch is against the current CVS version. I would appreciate
    if someone with CVS checkin permissions could check the changes
    in.

    The patch contains all bugs and patches sent this week and also
    fixes a leak in the codecs code and a bug in the free list code
    for Unicode objects (which only shows up when compiling Python
    with Py_DEBUG; thanks to MarkH for spotting this one).
